You have been insulted, your ego is bruised, your
pride is hurt, you have been shown powerless and diminished in some way, and now you are hurt
and mad as hell! You have just
been humiliated, it is unfair, and you don't like feeling foolish. Humiliation often results
in violent retaliation and revenge.
Remember, at the end of the day, the only opinion of yourself that matters is
- Feeling disrespected.
- A loss of stature or image.
- An image change reflecting a decrease in what others believe about your
- Induced shame
- To reduce the pride or fail to recognize the
dignity of another
- An event perceived to cause loss of honor and induce
- Feeling powerless.
- Being unjustly forced into a degrading position.
- Ridicule, scorn, contempt or other treatment at the hands of others.
Root: from Latin humilis, low, lowly, from humus, ground.
Literally, “reducing to dirt”.
Synonyms include losing face, being made to feel like a fool, feeling
foolish, hurt, disgraced, indignity, put-down, debased, dejected, denigrated, dishonored,
disrespected, dis'ed, defamed,
humbled, scorned, slighted, slurred, shamed, mortified, rejected, being laughed
at. While humility is considered a strength, humiliation is hurtful; the
distinction pivots on autonomy.
Appreciation is the opposite of humiliation.
Humiliation involves an event that demonstrates unequal
power in a relationship where you are in
the inferior position and unjustly diminished. Often the painful experience is vividly
remembered for a long time. Your vindictive
passions are aroused and a humiliated fury may
result. There are three involved parties: 1) the perpetrator
exercising power, 2) the victim who is shown powerless and therefore humiliated,
and 3) the witness or observers to the event.
Because of the powerlessness and lack of control that it exposes, humiliation
may lead to anxiety.
Humility is recognizing and accepting our own limitations based on
an accurate and modest estimate of our importance and significance. The humble person
recognizes he is one among the six billion
interdependent people on this earth, earth is one planet circling the sun, and our sun
is one of a billion stars in
the presently known universe. Because of this broad and sound perspective on her
significance, the truly humble person cannot be humiliated.
Humility reduces our need for self-justification
and allows us to admit to and learn from our mistakes. Our ego
Humiliation and Shame
Shame is private, humiliation is public.
The essential distinction between humiliation and shame is this: you agree
with shame and you disagree with humiliation. Humiliation is suffering an insult. If you judge the insult to be credible,
then you feel shame. Others can insult and humiliate
you, but you will only feel shame if your self-image is reduced; and that
requires your own assessment and decision. A person who is insecure about their
genuine stature is more prone to feeling shame as a
result of an insult. This is because they give more credibility to what others
think of them than to what they think of themselves. This can result in
People believe they deserve their shame, they do not believe they deserve
their humiliation. Humiliation is seen as unjust.
Forms of Humiliation
Humans have many ways to slight others and humiliate them. For example:
- Overlooking someone, taking them for granted, ignoring them, giving them
the silent treatment, treating them as invisible, or making them wait unnecessarily for you,
- Rejecting someone, holding them distant, abandoned, or isolated,
- Withholding acknowledgement, denying recognition, manipulating
- Denying someone basic social amenities, needs, or human
- Manipulating people or treating them like objects (it) or animals, rather
than as a person (thou).
- Treating people unfairly,
- Domination, control, manipulation, abandonment,
- Threats or abuse including: verbal (e.g. name calling), physical, psychological, or sexual,
- Assault, attack, or injury
- Reduction in rank, responsibility, role, title, positional power, or
- Betrayal, or being cheated, lied to, defrauded, suckered, or duped,
- Being laughed at, mocked, teased, ridiculed, given a dirty look, spit on, or made
to look stupid or foolish.
- Being the victim of a practical joke, prank, or confidence scheme.
- False accusation or insinuation,
- Public shame, disrespect, or being dis'ed, downgraded, defeated, or
- Forced nakedness,
- Rape or incest,
- Seeing your love interest flirt with another, induced jealousy, violating
your love interest, cuckolding,
- Seeing your wife, girlfriend, sister, or daughter sexually violated,
- Poverty, unemployment, bad investments, debt, bankruptcy, foreclosure, imprisonment, homelessness, punishment,
- Denigration of a person's values,
beliefs, heritage, race, gender,
appearance, characteristics, or affiliations,
- Dependency, especially on weaker people,
- Losing a dominance contest. Being
forced to submit.
- Trespass such as violating privacy or other boundaries,
- Violating, denying, or suppressing
- Losing basic personal freedoms such a mobility, access, or autonomy; being
controlled, dominated, intruded on, exploited, or manipulated,
- Diminished competency resulting from being disabled, immobilized, tricked,
weakened, trapped, mislead, thwarted goals, opposed, sabotage, or let down.
- Diminished resources resulting from being defrauded, robbed, cheated,
evicted, or being deprived of privileges, or rights,
- Having safety or security reduced by intimidation or threat,
- Dismissing, discounting, or silencing your story,
- Being treated as an equal by a lower stature person.
The Paradox of Humiliation
An insult usually hurts, but it is important to resolve in your own
mind, based on evidence, why the insult hurts. What
loss does it represent to you? Decide if the insult:
- is an unjustified attack that does not decrease your stature, diminish your
self-image, nor tarnish your public image or reputation, or
- is justified and has diminished your public image or reputation, or
- is justified and has diminished or revised your self-image.
Begin the analysis by deciding if the insult is based on information
that accurately represents you. Then reflect and consider if your
image accurately represents your stature. If you decide the insult is unjustified
then you can simply ignore it (“don't take the bait”) or you can describe why it
is unfair and ask your offender for an
apology. If your public image exceeds your stature, then
the insult may a justifiable retaliation for your arrogance and
it may contain an important message you can learn from. If the insult is
justified it may cause you to feel
shame and then lead you to revise your
better align it with your stature. The insult is never
justified if it is an attempt to reduce your stature below the threshold of human
Public Image, Self-Image, Stature, and Revenge
For an insult to diminish your public image, the
public has to believe it is true. For an insult to diminish your
self-image or self-esteem, you have to believe it is
true. An insult cannot diminish your stature because
your self-image is not your self. An insult may cause you to reassess your
self-image or self-esteem.
Revenge is often sought as a remedy for
humiliation; perhaps using the phrase “protecting honor” as justification. But
revenge cannot be an effective remedy for humiliation, because it does nothing
to increase your stature.
Humiliation is more demeaning and hurtful than “taking offense” at something.
“Taking offense” is cognitive; you have questioned, disagreed with, or attacked
my beliefs and perhaps my values. We disagree, and I
think you are wrong. Offense is intellectual; it is about what I think.
“Humiliation” is visceral; you have attacked me, my being, my
self, and made me feel foolish about who I am. The attack is personal and
credible enough that you have caused me to doubt my own worth, and thereby
induced my shame. Humiliation is existential; it is
about who I am.
Humiliation has been linked to academic failure, low
self-esteem, social isolation,
conflict, delinquency, abuse, discrimination,
depression, learned helplessness, social
disruption, torture, and even death. People in power use humiliation as a form
of social control; it is a common tool of oppression. The fear of humiliation is
also a powerful motivating force.
Although shame and humiliation are
human universals, the particular circumstances
and events that cause humiliation can vary greatly from one culture to the next.
An event that is benign in one culture may cause great offense, shame, and
humiliation in another. For example:
- Under Islamic law a woman who spends time alone with an unrelated man
brings great shame to her family.
Victims of humiliation may be able to achieve resolution through either of
two paths. The first is to reappraise the
humiliating experience in some way that acknowledges the victim's strength and ability
to cope with a difficult situation. This approach
increases self-confidence and diminishes the fear of humiliation. The second
path is to leave the degrading environment and find a more appreciative

Joseph Farwell Glidden: The Father of Barbed Wire
Joseph Farwell Glidden was born on January 18, 1813, and became known as the "Father of Barbed Wire." In 1874, Glidden was issued patent #157,124 for the first wire technology that was capable of restraining cattle. While his barbed wire was neither the first nor the last, it was ruled the best after a three year legal battle. | <urn:uuid:129ddbc9-ea36-48c5-a7c9-87082d42e4c8> | http://www.mexicoledger.com/article/20130118/blogs/130118772/0/features |

For many people in the United States, food comes from the grocery store. Most Americans would be hard pressed to determine the real origins of much of the food we eat. But residents of the Cayos Cochinos islands off the northern coast of Honduras know exactly where their food comes from: the ocean outside their doors.
Here, it’s not just their stomachs that rely on the bounty of the ocean—it’s almost their entire economy. But overfishing and industrial fishing continues to put pressure on their marine resources. The Nature Conservancy is working with partners and locals to protect their reefs through education, conservation and income-generating projects.
In 2007, the Conservancy and the Cayos Cochinos Foundation identified almost 20 income-generating projects with the goal of increasing income for households that depend heavily on the reef.
One of these projects was the construction of a small tourist complex managed by the East End community. The community hopes to attract tourists with two eco-friendly cabins, which were built with outside funding, and an ocean-view restaurant serving traditional Garifuna meals, funded by the Conservancy. The Conservancy is connecting the community with tourism service providers to promote best practices and ensure the protection of conservation targets.
The Cayos Cochinos Foundation, along with the Conservancy and other groups, has also worked with the communities to establish management plans that encourage no-take zones and the construction of artificial reefs that serve as nurseries for small fish. And through other partnerships, laws have been passed that will eventually prohibit industrial fishing around the marine protected area.
All of these initiatives are important in creating sustainability in the reefs and communities of Cayos Cochinos. According to Francisco Velasquez, a school teacher in East End, if it weren’t for the Conservancy, they wouldn’t still be living on that island.
“Our livelihood depends on fishing, but in the past large ships would come in and sweep the whole ocean clear of fish. There was nothing left for us to eat,” Velasquez said. “But now with the conservation of this area the fish are returning, and through the tourism project we are creating new solutions to increase our income and improve our lives.”
In Cayos Cochinos, these projects would not have been possible without Anthony Ives. A former San Francisco stock trader who at one point was managing 50 billion dollars for the state of California, Ives found his way to Honduras after Sept. 11 through the Peace Corps. He created the Foundation Heart Ventures-Grupo de Apoyo al Desarollo (IHV-GAD) to have a focus on education, conservation and job creation, with the idea that it is not possible to separate the three objectives.
“We have found that an integrated approach is much more sustainable, and we’re very happy that the Conservancy shares our long-term vision to sustainable conservation,” Ives said. “We hope to convince other organizations that through an integrated approach that involves education, we can achieve sustainable development while focusing on the environment.”January 03, 2011 | <urn:uuid:b11ad61b-8c0a-48c9-a3ec-7b45dddc2988> | http://www.nature.org/ourinitiatives/regions/africa/wherewework/cayos-cochinos.xml |

Multiple Sclerosis in Children
Story Updated: Feb 1, 2013
A new study suggests obese girls may be at increased risk for multiple sclerosis.
Researchers in California identified 75 children, aged 2 to 18, who had been diagnosed with MS. Records of body mass index before symptoms appeared were also accessed.
The children with MS were then compared to more than 900-thousand children without the disease.
All were grouped by weight - normal, overweight, moderately obese or extremely obese.
Nearly 51-percent of the children with MS were overweight or obese, compared to 37-percent of the children who did not have MS.
The risk of developing MS was more than 1-and-half times higher for overweight girls compared to normal weight girls nearly 1-point-8 times higher in moderately obese girls- and nearly four times higher in extremely obese girls.
The same association was not found in boys.
Once considered rare in children, multiple sclerosis
has become more common, especially in teenage girls. Researchers say an increase in childhood obesity may be one cause.

1938 Buick Y Job
Concept cars have been a mainstay of automotive design and marketing for more than a century. While Henry Leland's Osceola is considered the world's first concept car that actually made it into production, the 1938 Buick Y Job is another early example of a true concept car.
Built under the direction of General Motors' first design director, Harley Earl, the Y-Job was never intended for production but instead foreshadowed the styling and engineering cues Earl and his team hoped to use on future GM vehicles. In its day, the Y-Job earned praise for its modern style that included integrated fenders, hidden headlamps, and no running boards. The positive reaction helped several of its design cues to make it into production, including the stubby tail fins that would appear on the iconic 1948 Cadillacs and the grille design that continues to influence Buick design.
Although the Y-Job didn't make production, it remains an example of the good a concept car can do for a company and the industry. We can't help but wonder what would have happened, though, if Buick put the Y-Job into production. The company would have been in an even better position postwar. | <urn:uuid:ad4a1d4a-8865-41be-8049-a5e2afc9f982> | http://autos.yahoo.com/news/11-concept-cars-that-should-have-made-it.html?page=11 |
China has worked actively and seriously to tackle global climate change and build capacity to respond to it. We believe that every country has a stake in dealing with climate change and every country has a responsibility for the safety of our planet. China is at a critical stage of building a moderately prosperous society on all fronts, and a key stage of accelerated industrialization and urbanization. Yet, despite the huge task of developing the economy and improving people’s lives, we have joined global actions to tackle climate change with the utmost resolve and a most active attitude, and have acted in line with the principle of common but differentiated responsibilities established by the United Nations. China voluntarily stepped up efforts to eliminate backward capacity in 2007, and has since closed a large number of heavily polluting small coal-fired power plants, small coal mines and enterprises in the steel, cement, paper-making, chemical and printing and dyeing sectors. Moreover, in 2009, China played a positive role in the success of the Copenhagen conference on climate change and the ultimate conclusion of the Copenhagen Accord. In keeping with the requirements of the Copenhagen Accord, we have provided the Secretariat of the United Nations Framework Convention on Climate Change with information on China’s voluntary actions on emissions reduction and joined the list of countries supporting the Copenhagen Accord.
The targets released by China last year for greenhouse gas emissions control require that by 2020, CO2 emissions per unit of GDP should go down by 40% - 45% from the 2005 level, non-fossil energy should make up about 15% of primary energy consumption, and forest coverage should increase by 40 million hectares and forest stock volume by 1.3 billion cubic meters, both from the 2005 level. The measure to lower energy consumption alone will help save 620 million tons of standard coal in energy consumption in the next five years, which will be equivalent to the reduction of 1.5 billion tons of CO2 emissions. This is what China has done to step up the shift in economic development mode and economic restructuring. It contributes positively to Asia’s and the global effort to tackle climate change.
Ladies and Gentlemen,
Green and sustainable development represents the trend of our times. To achieve green and sustainable development in Asia and beyond and ensure the sustainable development of resources and the environment such as the air, fresh water, ocean, land and forest, which are all vital to human survival, we countries in Asia should strive to balance economic growth, social development and environmental protection. To that end, we wish to work with other Asian countries and make further efforts in the following six areas.
First, shift development mode and strive for green development. To accelerate the shift in economic development mode and economic restructuring provides an important precondition for our efforts to actively respond to climate change, achieve green development and secure the sustainable development of the population, resources and the environment. It is the shared responsibility of governments and enterprises of all countries in Asia and around the world. We should actively promote a conservation culture and raise awareness for environmental protection. We need to make sure that the concept of green development, green consumption and a green lifestyle and the commitment to taking good care of Planet Earth, our common home are embedded in the life of every citizen in society.
Second, value the importance of science and technology as the backing of innovation and development. We Asian countries have a long way to go before we reach the advanced level in high-tech-powered energy consumption reduction and improvement of energy and resource efficiency. Yet, this means we have a huge potential to catch up. It is imperative for us to quicken the pace of low-carbon technology development, promote energy efficient technologies and raise the proportion of new and renewable energies in our energy mix so as to provide a strong scientific and technological backing for green and sustainable development of Asian countries. As for developed countries, they should facilitate technology transfer and share technologies with developing countries on the basis of proper protection of intellectual property rights.
Third, open wider to the outside world and realize harmonious development. In such an open world as ours, development of Asian countries and development of the world are simply inseparable. It is important that we open our markets even wider, firmly oppose and resist protectionism in all forms and uphold a fair, free and open global trade and investment system. At the same time, we should give full play to the role of regional and sub-regional dialogue and cooperation mechanisms in Asia to promote harmonious and sustainable development of Asia and the world.
Fourth, strengthen cooperation and sustain common development. Pragmatic, mutually beneficial and win-win cooperation is a sure choice of all Asian countries if we are to realize sustainable development. No country could stay away from or manage to meet on its own severe challenges like the international financial crisis, climate change and energy and resources security. We should continue to strengthen macro-economic policy coordination and vigorously promote international cooperation in emerging industries, especially in energy conservation, emissions reduction, environmental protection and development of new energy sources to jointly promote sustainable development of the Asian economy and the world economy as a whole.
Fifth, work vigorously to eradicate poverty and gradually achieve balanced development. A major root cause for the loss of balance in the world economy is the seriously uneven development between the North and the South. Today, 900 million people in Asia, or roughly one fourth of the entire Asian population, are living below the 1.25 dollars a day poverty line. We call for greater efforts to improve the international mechanisms designed to promote balanced development, and to scale up assistance from developed countries to developing countries, strengthen South-South cooperation, North-South cooperation and facilitate attainment of the UN Millennium Development Goals. This will ensure that sustainable development brings real benefits to poor regions, poor countries and poor peoples.
Sixth, bring forth more talents to promote comprehensive development. The ultimate goal of green and sustainable development is to improve people’s living environment, better their lives and promote their comprehensive development. Success in this regard depends, to a large extent, on the emergence of talents with an innovative spirit. We need to build institutions, mechanisms and a social environment to help people bring out the best of their talents, and to intensify education and training of professionals of various kinds. This will ensure that as Asia achieves green and sustainable development, our people will enjoy comprehensive development.
Ladies and Gentlemen,
We demonstrated solidarity as we rose up together to the international financial crisis in 2009. Let us carry forward this great spirit, build up consensus, strengthen unity and cooperation and explore a path of green and sustainable development. This benefits Asia. It benefits the world, too.
In conclusion, I wish this annual conference of the Boao Forum for Asia a complete success. | <urn:uuid:648ee2b5-f8cd-4273-8ab0-29206d637638> | http://news.xinhuanet.com/english2010/china/2010-04/11/c_13245754_2.htm |
There is new scientific evidence to support the time-honored advice to students cramming for exams to get themselves a good night's sleep after studying.
Researchers who analyzed brain activity in sleeping volunteers who had learned to navigate through a computer-generated virtual town have discovered evidence that spatial memories are consolidated during deep sleep.
Also, the researchers say that they have shown for the first time that the activity level in the brain's learning center, the hippocampus, correlates with the improvement in memory performance when the subjects are tested the next day.
According to Philippe Peigneux and his colleagues, "A growing body of experimental evidence shows the influence of sleep on the consolidation of recent memory traces. The underlying hypothesis posits that the information that is acquired during wakefulness is actively altered, restructured, and strengthened during sleep."
However, they said, exploring this consolidation process was difficult because of the complexities of both sleep and memory. For example, sleep consists of two major stages -- rapid eye movement (REM) sleep and non rapid eye movement (NREM) sleep. Evidence from animal studies of learning and sleep indicated that spatial memories seem to be replayed in the hippocampus during the deep "slow wave sleep" (SWS) during the NREM sleep stage.
Peigneux and his colleagues explored the memory consolidation process by asking volunteers to learn the layout of a virtual town that the researchers adapted from a popular computer game. They then tested the subjects on their knowledge of the town by challenging them to quickly find routes through the town to specific locations.
The researchers divided the subjects into three experimental groups:
- one that underwent training in the virtual town and whose brains were scanned during testing while they were awake;
- one that underwent training and testing and whose brains were then scanned during sleep;
- one that did not undergo any training and whose brains were scanned.
The researchers measured the subjects' brain activity using positron emission tomography (PET) to measure blood flow in the subjects' brain regions. In PET, test subjects receive a harmless dose of radioactive tracer, and their brains are scanned as the tracer infuses through the brain. Blood flow through specific brain structures constitutes a measure of activity in that structure.
The researchers found that the first group -- compared to the non-trained group -- showed greater activity in their hippocampus and an adjacent learning-related region as they took the route tests, with greater activity correlated with better performance. The group scanned during sleep after testing also showed greater hippocampal brain activity during sleep, compared to the non-trained group.
Importantly, when the researchers compared the hippocampal activity during SWS sleep in the trained group and the non-trained group, they found that the first group showed higher activity.
Next, the researchers tested the trained group after their sleep session and compared their performance with the brain activity measured during sleep. They found that the higher the gain in post-sleep performance, the higher had been their NREM brain activity during sleep. No such correlation was found in REM brain activity.
To ensure that they were, indeed, measuring brain activity due to spatial processing, Peigneux and his colleagues also compared brain activity data from the spatially trained group with data from a fourth group that had only taken a reaction time test. In that test, the subjects' brains were scanned as they pressed a key as fast and accurately as possible corresponding to the location of a dot on a computer screen.
Thus, the data from the fourth group allowed the researchers to distinguish brain activity changes due to spatial processing from those due to general mental processing. The researchers' comparisons of the brain activity in the groups confirmed that the hippocampal activity they detected was due to spatial processing.
"Our results provide critical evidence that spatial memory traces are processed during NREM sleep in humans," wrote the scientists. "Moreover, the hippocampal activity during sleep is shown to correlate with the improvement in memory performance on the next day. To the extent of our knowledge, this effect has not yet been reported in the animal hippocampus."

Discovered in 1988, the Roman Hippodrome in Beirut is situated in Wadi Abou Jmil, next to the newly renovated Jewish Synagogue in Downtown Beirut. This monument, dating back for thousands of years, now risks to be destroyed.
The hippodrome is considered, along with the Roman Road and Baths, as one of the most important remaining relics of the Byzantine and Roman era. It spreads over a total area of 3500 m2.
Requests for construction projects in the hippodrome’s location have been ongoing since the monument’s discovery but were constantly refused by former ministers of culture of which we name Tarek Metri, Tamam Salam and Salim Warde. In fact, Tamam Salam had even issued a decree banning any work on the hippodrome’s site, effectively protecting it by law. Salim Warde did not contest the decree. Current minister of culture Gabriel Layoun authorized constructions to commence.
When it comes to ancient sites in cities that have lots of them, such as Beirut, the current adopted approach towards these sites is called a “mitigation approach” which requires that the incorporation of the monuments in modern plans does not affect those monuments in any way whatsoever. The current approval by minister Layoun does not demand such an approach to be adopted. The monument will have one of its main walls dismantled and taken out of location. Why? to build a fancy new high-rise instead. Minister Layoun sees nothing wrong with this. In fact, displacing ruins is never done unless due to some extreme circumstances. I highly believe whatever Solidere has in store for the land is considered an “extreme circumstance.”
The Roman Hippodrome in downtown Beirut is considered as one of the best preserved not only in Lebanon, but in the world. It is also the fifth to be discovered in the Middle East. In fact, a report (Arabic) by the General Director of Ruins in Lebanon, Frederick Al Husseini, spoke about the importance of the monument as one that has been talked about in various ancient books. It has also been correlated with Beirut’s infamous ancient Law School. He speaks about the various structures that are still preserved and only needing some restoration to be fully exposed. He called the monument as a highly important site for Lebanon and the world and is one of Beirut’s main facilities from the Byzantine and Roman eras, suggesting to work on preserving and making this site one of Beirut’s important cultural and touristic locations. His report dates back from 2008.
MP Michel Aoun, the head of the party of which Gabriel Layoun is part, defended his minsiter’s position by saying that: “there are a lot of discrepancies between Solidere and us. Therefore, a minister from our party cannot be subjected to Solidere. Minister Layoun found a way, which is adopted internationally, to incorporate ancient sites with newer ones… So I hope that media outlets do not discuss this issue in a way that would raise suspicion.”
With all due respect to Mr. Aoun and his minister but endangering Beirut’s culture to strip away even more of the identity that makes it Beirut is not something that should concern him or Solidere. What’s happening is a cultural crime to the entirety of the Lebanese population, one where the interests of meaningless politicians becomes irrelevant. Besides, for a party that has been anti-Solidere for years, I find it highly hypocritical that they are allowing Solidere to dismantle the Roman Hippodrome.
The conclusion is: never has a hippodrome been dismantled and displaced in any parts of the world. Beirut’s hippodrome will effectively become part of the parking of the high-rise to be built in its place. No mitigation approach will be adopted here. It is only but a diversion until people forget and plans go well underway in secrecy. But the time for us to be silent about this blatant persecution of our history cannot continue.
If there’s anything that we can do is let the issue propagate as much as we can. There shouldn’t be a Lebanese person in the 10452 km2 that remains clueless about any endangered monument for that matter. Sadly enough, this goes beyond the hippodrome. We have become so accustomed to the reality of it that we’ve become very submissive: the ancient Phoenician port is well behind us, there are constructions around the ancient Phoenician port of Tyre and the city itself risks of being removed off UNESCO’s list for Cultural Heritage Sites.
The land on which ancient monuments are built doesn’t belong to Solidere, to the Ministry of Culture or to any other contractor – no matter how much they’ve paid to buy it. It belongs to the Lebanese people in their entirety. When you realize that of the 200 sites uncovered at Solidere, those that have remained intact can be counted with the fingers of one hand, the reality becomes haunting. It’s about time we rise to our rights. Beirut’s hippodrome will not be destroyed. | <urn:uuid:996b9ec7-7a4b-4f7e-abcf-dc25c231bf57> | http://stateofmind13.com/2012/03/18/save-beiruts-heritage-the-roman-hippodrome-to-be-demolished/ |
The effect of monocular depth cues on the detection of moving objects by a moving observer
As observers move through the environment, they must detect moving objects. Previously, we showed that observers can use 2D image speed to detect moving objects in the radial optic flow field generated by a moving observer. However, a difference in image speed may signal either a moving object or a depth difference between stationary objects. Adding depth information may remove this ambiguity. We tested observers' ability to detect a moving object in scenes that contained increasingly salient monocular depth cues. We simulated observer motion in a straight line at a speed of 3 m/sec toward a scene that consisted of a textured ground plane with 8 objects located 12 m from the observer. In two conditions the objects were featureless red disks (diameter: 0.4 m) located on the horizontal midline that were either separate from the ground plane (condition 1) or connected to it with a thin line, giving a cue to distance (condition 2). In condition 3, the objects were textured blocks (width: 0.55 m; height: 1.6 m) located on the ground plane, giving further cues to depth. In half the trials one object moved faster (or slower) than the other objects in the scene. The speed differences ranged from 10% to 100% of the image speed of non-targets. Each trial lasted 1 sec. Observers indicated with a key press whether or not the scene contained a moving object. Thresholds were computed by fitting the data with a sigmoidal curve and determining the percent speed difference that led to 75% accuracy. For the 6 subjects tested, the results show a significant effect of scene condition, with average threshold speed changes of 43%, 37% and 25% for conditions 1, 2 and 3, respectively. Thus, monocular depth cues aid the detection of moving objects by moving observers. | <urn:uuid:a158182d-fb82-4e81-8a98-e03ba2385ba5> | http://www.citeulike.org/user/nnavarro/article/11287643 |
Basics: What is the GRE®?
The Graduate Record Examination (GRE®) is a standardized test used by graduate programs to help determine who gets in and who receives grants and fellowships. The exam comes in two types: the general exam, which covers a range of non-specific skills developed over a long period of time and years of schooling, and the subject tests, which test depth of knowledge in eight different fields. Worldwide, about half a million people take the general test each year, while a much smaller number takes the subject exams.
The general test is computer-based and consists of three sections, verbal, quantitative, and analytical writing. Verbal and quant are each scored on a scale of 130-170, in 1-point increments, plus a percentile rank. The writing section is scored on a scale of 0-6, in half-point increments. The test does not cover specifics in any field of study, but rather a set of skills thought to be important for prospective grad students.
The subject tests, on the other hand, are paper-based and administered 3 times a year. Unlike the general test, the subject test assumes extensive knowledge. Tests cover the following areas: Biochemistry, Cell and Molecular Biology; Biology; Chemistry; Computer Science; Literature in English; Mathematics; Physics; and Psychology. To determine whether you should take the general test or one of these subject-specific exams, you’ll need to check with the programs where you’re applying. For any field without a subject test, you’ll take the general exam.

Forty years ago, the Navajo Nation and Southern Ute tribes languished side by side, mired in high unemployment and poverty.
Today, worth billions, the Southern Ute Indian Tribe is one of the richest in the United States, while the Navajo still suffer as one of the most impoverished communities in the country.
The difference? Energy.
While the Southern Utes have natural gas, the Navajo Nation has coal, which has for decades been extracted to feed various large-scale power plants, including in the Four Corners. But that revenue has come under threat by tightening air-quality regulations. At the same time, natural gas, a cleaner fuel source for generating electricity, has grown cheaper and more abundant because of hydraulic fracturing.
The shift has left Navajo leaders in a quandary: either continue investing in coal in the hopes it will remain a significant fuel source, or cut their losses and choose another investment.
The tribe is staking its future on coal.
The Navajo Nation is in negotiations to buy the Navajo Mine from BHP Billiton in 2016 when BHP's lease expires.
Opponents say all the deal will do is saddle the tribe with a huge environmental cleanup. Tribal leaders say coal is a viable fuel source, and buying the Navajo Mine will save jobs and provide a foundation for the tribe to build a formidable energy portfolio similar to the Southern Utes.
Tribal leaders' plans will have far-reaching effects, not only for members – some of whom still live without electricity or plumbing – but also for residents throughout the region, who have seen haze cloud their views and threaten their health.
“We see how Southern Ute is using natural resources to advantage the tribe. We think they're doing well as far as adapting with the times,” said Navajo member Dailan Long, whose family lives near the Navajo Mine that is close to Fruitland on Navajo land.
“I definitely see a much older mind-set managing our economy, which has gotten us to the point where we are now. I think they (the Navajo leaders) could take a much more rational and logical approach to energy alternatives,” said Long, who formerly worked for Diné Citizens Against Ruining Our Environment, a Navajo environmental-activist organization.
The fossil fuel of the future
Dust billows at the Navajo Mine as a dragline excavator scoops dirt into its bucket and transfers it into a pile nearby, exposing coal for a bulldozer to grab.
Workers pour an ammonium-nitrate fuel-oil mixture into holes dug into the side of the mine to later blow up sections to reveal more coal in its depths.
The coal mine accounted for $53.6 million in direct revenue in 2012, about $110 million when taking into account lease and royalty revenue.
The 33,000-acre surface mine supplies the Four Corners Power Plant, about nine miles north, with about 8 million tons of coal a year.
BHP and Arizona Public Service approached Navajo Nation this summer about buying the Navajo Mine after the two entities failed to reach an agreement over coal prices, said Erny Zah, spokesman for the Navajo Nation president.
Under the preliminary negotiations, the tribe would give any federal and state tax revenue to BHP until 2016, when BHP's lease ends to pay for the mine, Zah said.
It's unclear who would take on the legal liabilities associated with eventual mandatory cleanup of the mine. The Navajo Nation emphatically says the tribe will not be responsible, and BHP says the issue is still part of the negotiations.
Going against the national energy tide
While global demand for coal remains high, coal production in the United States dropped about 7 percent in 2012, according to the U.S. Department of Energy. Coal still provided 42 percent of the nation's electricity in 2011, but just four years ago, it was providing nearly half.
“If we're talking about coal development and revenue as a major source of funding for the tribe, why didn't they negotiate this (sale) decades ago?” Long said.
He believes BHP wants to walk away from the cleanup responsibilities and leave the tribe with the bill.
“I think that it's definitely an exit strategy on behalf of BHP,” he said.
In contrast, the Southern Utes have focused on energy sources that will likely grow.
In 2008, the Southern Utes formed a separate company to manage its new-energy investments that include wind farms and biofuel projects.
The U.S. Energy Information Administration expects coal power to decline to 35 percent of total American electricity generation by 2040. Natural gas is expected to generate 30 percent of the nation's electricity within three decades.
Navajo Nation tribal officials acknowledge the new energy realities and have invested in alternatives, especially natural gas. Oil and gas contributed $48 million in revenue to the tribe in 2012.
The tribe also has invested in an 850-megawatt wind farm.
But coal will nonetheless remain the centerpiece of Navajo Nation's energy portfolio moving forward.
“We want to make sure coal is part of the picture for at least another couple of decades, if not longer,” Zah said.
But tightening environmental regulations that shutter coal-fired power plants could further strangle coal production.
Mike Eisenfeld and other environmental activists don't anticipate the Four Corners Power Plant will remain open for more than 10 years, as federal scrutiny of its environmental impact increases.
“I don't think they're sustainable now, and the sooner we figure out a transition plan to wean ourselves from big coal plants the better,” said Eisenfeld, New Mexico energy coordinator for the San Juan Citizen's Alliance.
APS is decommissioning its three oldest generating units at the Four Corners Power Plant rather than install new equipment to meet EPA regulations. This will result in a 30 percent reduction in production at Navajo Mine and layoffs at both the mine and power plant.
For a tribe with a roughly 50 percent unemployment rate and more than 50 percent of its members living below the poverty level, the closure will be a painful blow.
“One of the reasons we're exploring the possibility of taking over Navajo Mine is we're looking at saving jobs at the mine and also at the power plant because one cannot exist without the other,” Zah said.
If the power plant closes, Navajo Mine may have to shut its doors. This was the fate of the Black Mesa Mine in 2006 after the Mohave Generating Station, near Laughlin, Nev., which it supplied, shut down.
Navajo Nation's other plans to secure a future for its coal haven't been met with much success.
In 2003, The Navajo Nation proposed a new coal-fired power plant called the Desert Rock Energy Project, which would be supplied by an expanded Navajo Mine.
Under the project, international energy developer Sithe Global Power would have built a new 1,500-megawatt power plant on Navajo land about 25 miles outside Farmington. The plant would have been among the largest in the country, and it would have provided electricity for 1.5 million customers.
The tribe heralded the power plant as an economic victory, saying it would provide 400 jobs at the Desert Rock power plant, 200 additional jobs at Navajo Mine and $50 million in annual revenue – almost half of Navajo Nation's current total coal revenue.
The EPA approved Desert Rock in 2008 and touted it as “state-of-the-art,” but the agency reconsidered the project's air permit after New Mexico joined environmental groups in appealing the EPA's initial approval. In 2009, the EPA reversed its decision and revoked the air permit.
For the Navajos, losing the project was a crushing blow.
“(Navajo Nation) viewed Desert Rock as a huge economic opportunity,” said Tom Shipps, an Indian law lawyer who works for Colorado's Southern Ute tribe. “The technology employed at Desert Rock could have been great improvements. Concerns about the environment drove a lot of the criticism, especially around here.”
The project remains in the back of tribal leader's minds, Zah said. One idea is to convert it to a natural-gas plant.
Still, the question of what to do with the Navajo Mine would remain if a new power plant were to run on natural gas.
In the meantime, coal is the focus of the tribe's energy strategy.
BHP gives a qualified endorsement of that strategy.
“Coal will continue to be an important part of meeting the energy needs of the U.S.,” Norman Benally, spokesperson for BHP, said. “Granted there are mandates coming from the EPA that are limiting the use of coal and in some areas shutting down power plants that generate electricity. But we believe coal will be part of the energy portfolio, though limited, until such time that renewable energies have or will become viable.” | <urn:uuid:99402d3d-84b9-4039-91d3-80d618c9faf3> | http://durangoherald.com/article/20130127/NEWS01/130129627/0/taxonomy/A-path-paved-in-coal-- |
A surprising amount of what we think we know about the brain comes from neuropsychology; famous case studies such as HM have informed theories of memory so that they include short and long term storage, which are separable, and so on. These case studies can have a profound effect on research; my favourite story, though, was about a memory researcher who had a skiing accident and temporarily developed retrograde amnesia - he couldn't remember anything except that there was this guy in Connecticut (HM) who couldn't remember things either!
I always enjoyed classes in neuropsychology; the case studies are always fascinating. But they are deeply limited in what they can actually tell us about the brain. First, they are typically single patient case studies, which restricts how general the conclusions are. Second, they are data from damaged brains; the fairly linear assumption that some localised function has been subtracted out is simply not true, and the damage will have had complex effects on distributed functional networks.Third, the damage is never straight-forward, because these almost all come from accidents or strokes (HM's surgery being a rare example of more detail being known). This has not stopped the field being very excited by these cases, though, and from basing a lot of theory on these patterns of deficits.
In movement research, the most famous neuropsychology case study is Patient DF She suffered bilateral damage along the ventral stream of visual processing (James et al, 2003). The effect was visual form agnosia: she is able to control her actions with respect to objects, but cannot describe or recognise these objects verbally. Crucially, her accident did not damage her parietal lobe; specifically, the dorsal stream of visual processing was left intact. These two streams are well defined anatomical pathways leading out of primary visual cortex, and were first described by Ungerleider & Mishkin, 1982). DF's pattern of deficits led Mel Goodale and David Milner (Goodale & Milner, 1992) to suggest functional roles for these streams. The ventral stream, they suggested, was for perception - things like object and scene recognition. The dorsal stream, in contrast, was for perception-for-action, and used visual information for the online control of action. This perception-action hypothesis has been hugely dominant in the field, and the theory rests heavily on DF's shoulders.
Recently, Thomas Schenk (2012a) published some data which claims to show that DF's visually guided reaching is not normal if she doesn't have access to haptic feedback about the object. His data suggests that the only reason she succeeds at reaching while failing judgment tasks is that haptic information is only normally available in the former case. If correct, this is actually quite a shot across the bow of the perception vs perception-for-action work; naturally Goodale and Milner don't buy it, and have published a reply to which Schenk has then replied.
I like seeing these arguments happen in the literature; but to be honest, the time scale is too slow. Schenk publishes, then Milner et al get to reply and Schenk gets right of reply to that. They may or may not iterate again and it's always left as 'we agree to disagree'. But these critiques have answers, and I think a blog comment feed might be the right place to work through the various cycles of suggestions and rebuttals until the obviously wrong things have been weeded out. It would also provide a place for other interested parties to weigh in. So if Schenk, Milner and Goodale (and anyone else!) feel like using the comments for this post or another made to purpose to bang around ideas until an obvious experiment or analysis pops out, please feel free!
Schenk (2012a): Patient DF and haptic feedback
The classic result from DF that inspired the Goodale and Milner account has two parts (a dissociation). When DF is asked to reach for an object, she can do so well and she shows appropriate pre-shaping of her hand which scales correctly with the size of the object. This suggests she has intact visual perception-for-action. However, if you ask her to judge the size of the object without reaching for it, she cannot do it; she has selectively impaired visual perception. Schenk ran the following experiments on DF and to demonstrate that her unimpaired reaching is not because of intact visual perception-for-action, but rather because of haptic feedback from real objects.
'Perception': these are the tasks DF typically fails due to her visual form agnosia, and she fails them here too.
- Size discrimination: Choose the largest of two objects
- Manual estimation: Judge the size of an object by shaping your hand correctly
- Standard grasping: Reach to grasp an object in the mirror and there is actually an object there (vision + haptic information match)
- Grasping without haptic feedback: Reach for the reflection but there is no actual object there.
- Grasping with intermittent haptic feedback: there was an object present on half the trials; these were scattered randomly throughout the session and a light cued participants when the object would be present.
- Grasping with dissociated positions: participants saw an object in the middle location, were asked to reach for an object at the far position, and there was a real object there.

Milner, Ganel & Goodale (2012)
Unsurprisingly, Milner et al (2012) do not agree that these data cast doubt on the perception-action hypothesis about the function of the dorsal and ventral streams. They make the following criticisms:
- They suggest that "so-called 'haptic feedback'" (to quote the paper) from trial n could only inform a reach on trial n+1 if the objects were the same size in both trials; object size was randomised across trials, however.
- They then claim that Schenk's interpretation means he thinks DF's reaches are prepared on the basis of previous haptic, rather than current visual information. Therefore, they suggest, Schenk must make 'the inescapable prediction' that a reach on trial n+1 should be appropriate for what happened on trial n, regardless of what is presented on trial n+1.They allow that there may be some 'minor intrusion' of haptic information from previous trials.
Again unsurprisingly, Schenk (2012b) does not agree with Milner et al's evaluation.
- He claims that the Milner et al critique assumes that prehension requires the visual computation of an object's size. He then cites recent work by Smeets & Brenner (1999) who claimed to show that prehension involves the independent targeting of the thumb and forefinger, and thus you don't need object size.
- He then suggests that DF is generally able to reach successfully because she has access to the necessary egocentric information (in hand-centred coordinates) about the location of object edges. This information requires regular calibration (Bingham et al, 2007) to remain accurate.
- He therefore predicts that if DF has egocentric information about the object, and this information has been calibrated recently, she can reach successfully, otherwise she fails. His 2012a data then support this pattern.
- Regarding the pantomime problem: Schenk tested this in Task 5 with the trials with no objects. DF knew there would be no object on these trials (the light cue) but still produced normal reaches because of the calibration on other trials.
There is a lot that is weird about the replies. Milner et al make some odd claims, and Schenk goes to strange places in his defence. Let's address those first.
1. "So-called 'haptic feedback'"
Milner et al want to keep claiming that DF reaches on the basis of current visual information, and not on the basis of previous haptic information. But there's a problem for them - this is the claim Schenk's data actually refutes! So they make an odd move, and simply claim that earlier haptic information does not affect reaches, and that even if it could, it won't here because the size changes from trial to trial.
However, Coats, Bingham & Mon-Williams (2008) have demonstrated (using a mirror rig similar to Schenk's) that if you systematically change the size of the grasped object while leaving the visual object the same size, people happily recalibrate their reach actions and change their grip apertures. Bingham et al (2007) have also shown that even occasional calibration allows stable reach behaviour to persist; calibration lasts some time. So even when the visual size remains unchanged, people's grip behaviour reflects the haptic calibration of the visual perception of size and if this calibration changes, so does grip.
Milner et al's second point - that haptic feedback can't help because the object size changes randomly - is actually addressed by Schenk's control data, which shows that neurologically intact people can happily scale their grips appropriately under these conditions (albiet slightly more noisily).
2. Reaching and the need for visual size
Schenk centres his reply on the idea that Milner et al assume you need to compute (or perceive) the size of objects in order to scale your grasp. He then cites Smeets & Brenner (1999) who claim that instead, you simply control your thumb and forefinger independently and bring them into alignment with the edges of the object.
The problem here is that Smeets & Brenner's work is highly controversial, and in fact more recent work from Mon-Williams & Bingham (2011) tested the predictions of this account in great detail and found no support for this claim. Instead, they showed that the unit of control is an opposition axis (Iberall, Bingham & Arbib, 1986). This is the space between the thumb and forefinger, and Mon-Williams & Bingham (2011) demonstrated that prehension is about aligning this space with the object. You do still therefore need to perceive object size, specifically the maximum object extent. I'll blog this paper in more detail sometime, it is a master class in affordance research.
I think Schenk had it basically right in the first paper; the explanation for his data is that in tasks 3 and 5, DF has sufficient access to haptic information about the object's size to allow her to bypass her visual perceptual deficit. She can therefore successfully reach to grasp. In all other tasks, she can't go round the problem and she fails. This suggests that her visual deficit is not simply restricted to 'perception'; the visual system involves both anatomical streams working in concert and these are not functionally independent of each other. What Schenk needs to do is treat haptic information as perceptual information for size in it's own right, not simply feedback or an 'egocentric cue'. DF has unimpaired access to this information and when it's available, she can reach-to-grasp.

Cougar sightings in Louisiana not that long ago were considered figments of the imagination of spooked hunters, hikers and others in the outdoors.
A citizen sent LDWF a trail camera picture taken Aug. 13, 2011. LDWF Large Carnivore Program Manager Maria Davidson and biologist Brandon Wear conducted a site investigation that confirmed the authenticity of the photograph.
“It is quite possible for this animal to be captured on other trail cameras placed at deer bait sites,” Davidson said. “Deer are the primary prey item for cougars; therefore, they are drawn to areas where deer congregate.”
It is unlikely this cougar will remain in any one area longer than it would take to consume a kill. Cougars do not prefer to eat spoiled meat and will move on as soon as the Louisiana heat and humidity take its toll on the kill.
“It is impossible to determine if the animal in the photograph is a wild, free-ranging cougar, or an escaped captive,” Davidson added. “Although it is illegal to own a cougar in Louisiana, it is possible that there are some illegally held ‘pets’ in the state.”
LDWF has documented several occurrences since 2002. The first cougar sighting was in 2002 by an employee at Lake Fausse Point State Park. That sighting was later confirmed with DNA analysis from scat found at the site.
Three trail camera photos were taken of a cougar in Winn, Vernon and Allen parishes in 2008. Subsequently on Nov. 30, 2008, a cougar was shot and killed in a neighborhood by Bossier City Police Department.
The mountain lion, cougar, panther or puma are names that all refer to the same animal. Their color ranges from lighter tan to brownish grey. The only species of big cats that occur as black are the jaguar and leopard. Jaguars are native to South America and leopards are native to Africa. Both species can occur as spotted or black, although in both cases the spotted variety is much more common. Although LDWF receives numerous calls about black panthers, there has never been a documented case of a black cougar anywhere in North America.
The vast majority of these reports received by LDWF cannot be verified due to the very nature of a sighting. Many of the calls are determined to be cases of mistaken identity, with dog tracks making up the majority of the evidence submitted by those reporting cougar sightings. Other animals commonly mistaken for cougars are bobcats and house cats, usually seen from a distance or in varying shades of light.
The significant lack of physical evidence indicates that Louisiana does not have an established, breeding population of cougars. In states that have verified small populations of cougars, physical evidence can readily be found in the form of tracks, cached deer kills, scat and road kills.
The recent sightings of cougars in Louisiana are believed to be young animals dispersing from existing populations. An expanding population in Texas can produce dispersing individual cougars that move into suitable habitat in Louisiana. Young males are known to disperse from their birthplace and travel hundreds of miles seeking their own territories.
Cougars that occur in Louisiana are protected under state and federal law. Penalties for taking a cougar in Louisiana may include up to one year in jail and/or a $100,000 fine. Anyone with any information regarding the taking of a cougar should call the Operation Game Thief hotline at 1-800-442-2511. Callers may remain anonymous and may receive a cash reward. | <urn:uuid:837ed0bb-0bd1-432c-9baf-a4a8b88595fc> | http://stmarynow.com/view/full_story/15264141/article-Images-confirm-cougar-presence-in-Vernon-Parish?instance=secondary_stories_left_column |

St. Louis MO (SPX) Feb 12, 2013
Nominated early this year for recognition on the UNESCO World Heritage List, which includes such famous cultural sites as the Taj Mahal, Machu Picchu and Stonehenge, the earthen works at Poverty Point, La., have been described as one of the world's greatest feats of construction by an archaic civilization of hunters and gatherers.
Now, new research in the current issue of the journal Geoarchaeology, offers compelling evidence that one of the massive earthen mounds at Poverty Point was constructed in less than 90 days, and perhaps as quickly as 30 days - an incredible accomplishment for what was thought to be a loosely organized society consisting of small, widely scattered bands of foragers.
"What's extraordinary about these findings is that it provides some of the first evidence that early American hunter-gatherers were not as simplistic as we've tended to imagine," says study co-author T.R. Kidder, PhD, professor and chair of anthropology in Arts and Sciences at Washington University in St. Louis.
"Our findings go against what has long been considered the academic consensus on hunter-gather societies - that they lack the political organization necessary to bring together so many people to complete a labor-intensive project in such a short period."
Co-authored by Anthony Ortmann, PhD, assistant professor of geosciences at Murray State University in Kentucky, the study offers a detailed analysis of how the massive mound was constructed some 3,200 years ago along a Mississippi River bayou in northeastern Louisiana.
Based on more than a decade of excavations, core samplings and sophisticated sedimentary analysis, the study's key assertion is that Mound A at Poverty Point had to have been built in a very short period because an exhaustive examination reveals no signs of rainfall or erosion during its construction.
"We're talking about an area of northern Louisiana that now tends to receive a great deal of rainfall," Kidder says. "Even in a very dry year, it would seem very unlikely that this location could go more than 90 days without experiencing some significant level of rainfall. Yet, the soil in these mounds shows no sign of erosion taking place during the construction period. There is no evidence from the region of an epic drought at this time, either."
Part of a much larger complex of earthen works at Poverty Point, Mound A is believed to be the final and crowning addition to the sprawling 700-acre site, which includes five smaller mounds and a series of six concentric C-shaped embankments that rise in parallel formation surrounding a small flat plaza along the river. At the time of construction, Poverty Point was the largest earthworks in North America.
Built on the western edge of the complex, Mound A covers about 538,000 square feet [roughly 50,000 square meters] at its base and rises 72 feet above the river. Its construction required an estimated 238,500 cubic meters - about eight million bushel baskets - of soil to be brought in from various locations near the site. Kidder figures it would take a modern, 10-wheel dump truck about 31,217 loads to move that much dirt today.
"The Poverty Point mounds were built by people who had no access to domesticated draft animals, no wheelbarrows, no sophisticated tools for moving earth," Kidder explains. "It's likely that these mounds were built using a simple 'bucket brigade' system, with thousands of people passing soil along from one to another using some form of crude container, such as a woven basket, a hide sack or a wooden platter."
To complete such a task within 90 days, the study estimates it would require the full attention of some 3,000 laborers. Assuming that each worker may have been accompanied by at least two other family members, say a wife and a child, the community gathered for the build must have included as many as 9,000 people, the study suggests.
"Given that a band of 25-30 people is considered quite large for most hunter-gatherer communities, it's truly amazing that this ancient society could bring together a group of nearly 10,000 people, find some way to feed them and get this mound built in a matter of months," Kidder says.
Soil testing indicates that the mound is located on top of land that was once low-lying swamp or marsh land - evidence of ancient tree roots and swamp life still exists in undisturbed soils at the base of the mound. Tests confirm that the site was first cleared for construction by burning and quickly covered with a layer of fine silt soil. A mix of other heavier soils then were brought in and dumped in small adjacent piles, gradually building the mound layer upon layer.
As Kidder notes, previous theories about the construction of most of the world's ancient earthen mounds have suggested that they were laid down slowly over a period of hundreds of years involving small contributions of material from many different people spanning generations of a society. While this may be the case for other earthen structures at Poverty Point, the evidence from Mound A offers a sharp departure from this accretional theory. Kidder's home base in St.
Louis is just across the Mississippi River from one of America's best known ancient earthen structures, the Monk Mound at Cahokia, Ill. He notes that the Monk Mound was built many centuries later than the mounds at Poverty Point by a civilization that was much more reliant on agriculture, a far cry from the hunter-gatherer group that built Poverty Point. Even so, Mound A at Poverty Point is much larger than almost any other mound found in North America; only Monk's Mound at Cahokia is larger.
"We've come to realize that the social fabric of these socieites must have been much stronger and more complex that we might previously have given them credit. These results contradict the popular notion that pre-agricultural people were socially, politically, and economically simple and unable to organize themselves into large groups that could build elaborate architecture or engage in so-called complex social behavior," Kidder says.
"The prevailing model of hunter-gatherers living a life 'nasty, brutish and short' is contradicted and our work indicates these people were practicing a sophisticated ritual/religious life that involved building these monumental mounds."

By Pauline Hammerbeck
It's been a doozy of a wildfire season (Colorado's most destructive ever), leaving homeowners wondering what safety measures they can put in place to stave off flames in the event of a fire in their own neighborhood.
Landscaping, it turns out, can be an important measure in wildfire protection.
But fire-wise landscaping isn't just something for those dwelling on remote Western hilltops. Brush, grass and forest fires occur nearly everywhere in the United States, says the National Fire Protection Association. Here's how your landscaping can help keep you safe.
Create 'defensible' space
Most homes that burn during a wildfire are ignited by embers landing on the roof, gutters, and on decks and porches. So your first point of action should be creating a defensible space, a buffer zone around your home, to reduce sources of fuel.
Start by keeping the first 3 to 5 feet around your home free of all flammable materials and vegetation: plants, shrubs, trees and grasses, as well as bark and other organic mulches should all be eliminated (a neat perimeter of rock mulch or a rock garden can be a beautiful thing). Maintenance is also important:
- Clear leaves, pine needles and other debris from roofs, gutters and eaves
- Cut back tree branches that overhang the roof
- Clear debris from under decks, porches and other structures
Moving farther from the house, you might consider adding hardscaping - driveways, patios, walkways, gravel paths, etc. These features add visual interest, but they also maintain a break between vegetation and your home in the event of a fire. Some additional tasks to consider in the first 100 feet surrounding your home:
- Thin out trees and shrubs (particularly evergreens) within 30 feet
- Trim low tree branches so they're a minimum of 6 feet off the ground
- Mow lawn regularly and dispose of clippings and other debris promptly
- Move woodpiles to a space at least 30 feet from your home
Use fire-resistant plants
Populating your landscape with plants that are resistant to fire can also be an important tactic. Look for low-growing plants that have thick leaves (a sign that they hold water), extensive root systems and the ability to withstand drought.
This isn't as limiting as it sounds. Commonly used hostas, butterfly bushes and roses are all good choices. And there are plenty of fire-resistant plant lists to give you ideas on what to pick.
Where and how you plant can also have a dramatic effect on fire behavior. The plants nearest your home should be smaller and more widely spaced than those farther away.
Be sure to use a variety of plant types, which reduces disease and keeps the landscape healthy and green. Plant in small clusters - create a garden island, for instance, by surrounding a group of plantings with a rock perimeter - and use rock mulch to conserve moisture.
Maintain accessible water sources
Wildfires present a special challenge to local fire departments, so it's in your interest to be able to access or maintain an emergency water supply - particularly if you're in a remote location.
At a minimum, keep 100 feet of garden hose attached to a spigot (if your water comes from a well, consider an emergency generator to operate the pump during a power failure). But better protection can come from the installation of a small pond, cistern or, if budget allows, a swimming pool.
Good planning and a bit of elbow grease have a big hand in wildfire safety. In a year with record heat and drought, looking over your landscape with a firefighter's eye can offer significant peace of mind.

Long Term Player Development
What is LTPD?
Long Term Player Development (LTPD) is a systemic approach being developed and adopted by Golf Canada in partnership with the Canadian Professional Golfers’ Association to maximize a participant's potential and involvement in our sport. The LTPD framework aims to define optimal training, competition and recovery throughout an athlete's career to enable him / her to reach his / her full potential in golf and as an athlete. Tailoring a child's sports development program to suit basic principles of growth and maturation, especially during the 'critical' early years of their development, enables him / her to:
- Reach full potential
- Increase lifelong participation in golf and other physical activities
The LTPD model is split into stages in which a player will move from simple to more complex skills and from general to golf related skills. For example, a beginner may start by learning basic swinging actions and then once this has been mastered he / she will progress onto more advanced skills.
This framework will set out recommended training sequences and skills developments for the participant from the Active Start stage (6 and under) to the Active for Live Stage (adult recreational). It will address the physical, mental, emotional and technical needs of the athlete as they pass through each stage of development.
Where has it come from?
A combination of recent research and the knowledge of coaches from around the world are being used to write the LTPD model. The program will be sport-science supported and based on the best data and research available. Our work will be based on the work of Canadian sport scientists, such as Istvan Bayyi, and focuses on key, common principles of individual development, which many sports organizations consider good practice in long-term planning for athletes.
Many leading sports stars have also attributed part of their success to participating in different sports and activities at a young age by giving them a wider base of sports skills. Our goal will be to develop our players to their maximum potential by training and enhancing all the athletic skills that contribute to their success.
What will this mean for your child?
During your child's first few years of golf, the emphasis will be on physical literacy. Time should be spent learning the ABC's of athleticism (Agility, Balance, Coordination and Speed) to teach them how to control his / her own bodies. For this reason, your child may take part in exercises that do not look relevant to golf but are supporting their development. Games and other sports will teach your child to throw the ball (basic hitting actions), catch it (hand-eye coordination), and run properly. At each stage the child will be trained in the optimal systems and programs to maximize his / her potential as a golfer and as a long-term participant in sport.
What has this got to do with golf?
It is thought that taking part in golf-specific training too early can lead to an early drop out rate, create muscle imbalances and also neglect teaching the fundamental skills needed for most sports. In fact, research shows that early specialization in most late maturing sports results in these outcomes.
Research has also shown that it is during childhood that people are best at learning physical skills. For this reason we are advising coaches and parents to teach transferable skills first that will allow your child to become proficient in a number of different sports and therefore increase their chances of being physically active throughout their lifetime.
Who else is using LTPD?
The Council of Federal, Provincial and Territorial Ministers responsible for Sport have endorsed and established the goal of the implementation of a Long Term Athlete Development program throughout the sport community in Canada. Sport Canada has been working with National Sport Organizations to development sport-specific programs according to an overall framework established by an expert group of sport scientists.
To date, over 57 sports in Canada have started the process of designing and putting into place LTAD programs. There has been a sharing of best practices among resource personnel and National bodies and the overall program is gaining momentum.
Golf Canada is in the second wave of sports to start the LTPD process and is following closely the work of such groups as Rowing Canada, Athletics Canada, Speedskating Canada and Soccer to create the best opportunities for all children.
Various national sporting groups in the UK and Ireland are approximately 18 months ahead of their Canadian counterparts in the development of LTPD programs and we are using their experiences and best practices in process development to ensure we have the most comprehensive and effective system possible.
Where will Golf's LTPD model come from?
We will be consulting with a wide range of coaches, sports scientists and experienced volunteers from across Canada to represent the views of the whole golf community. Their knowledge and expertise will be used as input to form the LTPD framework for golf in Canada. We will be assisted in this process by the LTPD Resource paper and research of the expert group, in particular Stephen Norris (see www.ltad.ca for resource paper).
In developing this model and framework, Golf Canada is currently in the process of reviewing our programs in line with LTPD principles. Our competition program, coach education system, elite play structure and development initiatives will all evolve to be consistent with the principles established within this underpinning model.
One of the principles to be adopted will be a continuous improvement regime where the system will be benchmarked against the most current developmental principles and upgraded regularly. It will be a living document that provides a planning framework to enable us to always deliver the most appropriate training.
Golf Canada LTPD resources
Golf Canada will continually update this section to provide access to the most current materials and programs as they are developed.
We will add a range of LTPD resources designed to help all Coaches, Teachers, Players and Parents understand the stages that each player goes through and also the training principles and activities at each stage.

Upland Bird Regional Forecast
When considering upland game population levels during the fall hunting season, two important factors impact population change. First is the number of adult birds that survived the previous fall and winter and are considered viable breeders in the spring. The second is the reproductive success of this breeding population. Reproductive success consists of nest success (the number of nests that successfully hatched) and chick survival (the number of chicks recruited into the fall population). For pheasant and quail, annual population turnover is relatively high; therefore, the fall population is more dependent on reproductive success than breeding population levels. For grouse (prairie chickens), annual population turnover is not as rapid although reproductive success is still the major population regulator and important for good hunting. In the following forecast, breeding population and reproductive success of pheasants, quail, and prairie chickens will be discussed. Breeding population data were gathered during spring breeding surveys for pheasants (crow counts), quail (whistle counts), and prairie chickens (lek counts). Data for reproductive success were collected during late summer roadside surveys for pheasants and quail. Reproductive success of prairie chickens cannot be easily assessed using the same methods because they generally do not associate with roads like the other game birds.
Kansas experienced extreme drought this past year. Winter weather was mild, but winter precipitation is important for spring vegetation, which can impact reproductive success, and most of Kansas did not get enough winter precipitation. Pheasant breeding populations showed significant reductions in 2012, especially in primary pheasant range in western Kansas. Spring came early and hot this year, but also included fair spring moisture until early May, when the precipitation stopped, and Kansas experienced record heat and drought through the rest of the reproductive season. Early nesting conditions were generally good for prairie chickens and pheasants. However, the primary nesting habitat for pheasants in western Kansas is winter wheat, and in 2012, Kansas had one of the earliest wheat harvests on record. Wheat harvest can destroy nests and very young broods. The early harvest likely lowered pheasant nest and early brood success. The intense heat and lack of rain in June and July resulted in a decrease in brooding cover and insect populations, causing lower chick survival for all upland game birds.
Because of drought, all counties in Kansas were opened to Conservation Reserve Program (CRP) emergency haying or grazing. CRP emergency haying requires fields that are hayed to leave at least 50 percent of the field in standing grass cover. CRP emergency grazing requires 25 percent of the field (or contiguous fields) to be left ungrazed or grazing at 75-percent normal stocking rates across the entire field. Many CRP fields, including Walk In Hunting Areas (WIHA), may be affected across the state. WIHA property is privately-owned land open to the public for hunting access. Kansas has more than one million acres of WIHA. Often, older stands of CRP grass are in need of disturbance, and haying and grazing can improve habitat for the upcoming breeding season, and may ultimately be beneficial if weather is favorable.
Due to continued drought, Kansas will likely experience a below-average upland game season this fall. For those willing to hunt hard, there will still be pockets of decent bird numbers, especially in the northern Flint Hills and northcentral and northwestern parts of the state. Kansas has approximately 1.5 million acres open to public hunting (wildlife areas and WIHA combined). The regular opening date for the pheasant and quail seasons will be Nov. 10 for the entire state. The previous weekend will be designated for the special youth pheasant and quail season. Youth participating in the special season must be 16 years old or younger and accompanied by a non-hunting adult who is 18 or older. All public wildlife areas and WIHA tracts will be open for public access during the special youth season. Please consider taking a young person hunting this fall, so they might have the opportunity to develop a passion for the outdoors that we all enjoy.
PHEASANT – Drought in 2011 and 2012 has taken its toll on pheasant populations in Kansas. Pheasant breeding populations dropped by nearly 50 percent or more across pheasant range from 2011 to 2012 resulting in fewer adult hens in the population to start the 2012 nesting season. The lack of precipitation has resulted in less cover and insects needed for good pheasant reproduction. Additionally, winter wheat serves as a major nesting habitat for pheasants in western Kansas, and a record early wheat harvest this summer likely destroyed many nests and young broods. Then the hot, dry weather set in from May to August, the primary brood-rearing period for pheasants. Pheasant chicks need good grass and weed cover and robust insect populations to survive. Insufficient precipitation and lack of habitat and insects throughout the state’s primary pheasant range resulted in limited production. This will reduce hunting prospects compared to recent years. However, some good opportunities still exist to harvest roosters in the sunflower state, especially for those willing to work for their birds. Though the drought has taken its toll, Kansas still contains a pheasant population that will produce a harvest in the top three or four major pheasant states this year.
The best areas this year will likely be pockets of northwest and northcentral Kansas. Populations in southwest Kansas were hit hardest by the 2011-2012 drought (72 percent decline in breeding population), and a very limited amount of production occurred this season due to continued drought and limited breeding populations.
QUAIL – The bobwhite breeding population in 2012 was generally stable or improved compared to 2011. Areas in the northern Flint Hills and parts of northeast Kansas showed much improved productivity this year. Much of eastern Kansas has seen consistent declines in quail populations in recent decades. After many years of depressed populations, this year’s rebound in quail reproduction in eastern Kansas is welcomed, but overall populations are still below historic averages. The best quail hunting will be found throughout the northern Flint Hills and parts of central Kansas. Prolonged drought undoubtedly impacted production in central and western Kansas.
PRAIRIE CHICKEN – Kansas is home to greater and lesser prairie chickens. Both species require a landscape of predominately native grass. Lesser prairie chickens are found in westcentral and southwestern Kansas in native prairie and nearby stands of native grass within the conservation reserve program (CRP). Greater prairie chickens are found primarily in the tallgrass and mixed-grass prairies in the eastern one-third and northern one-half of the state.
The spring prairie chicken lek survey indicated that most populations remained stable or declined from last year. Declines were likely due to extreme drought throughout 2011. Areas of northcentral and northwest Kansas fared the best, while areas in southcentral and southwest Kansas experienced the sharpest declines where drought was most severe. Many areas in the Flint Hills were not burned this spring due to drought. This resulted in far more residual grass cover for much improved nesting conditions compared to recent years. There have been some reports of prairie chickens broods in these areas, and hunting will likely be somewhat improved compared to recent years.
Because of recent increases in prairie chicken (both species) populations in northwest Kansas, regulations have been revised this year. The early prairie chicken season (Sept. 15-Oct. 15) and two-bird bag limit has been extended into northwest Kansas. The northwest unit boundary has also been revised to include areas north of U.S. Highway 96 and west of U.S. Highway 281. Additionally, all prairie chicken hunters are now required to purchase a $2.50 prairie chicken permit. This permit will allow KDWPT to better track hunters and harvest, which will improve management activities. Both species of prairie chicken are of conservation concern and the lesser prairie chicken is a candidate species for federal listing under the Endangered Species Act.
This region has 11,809 acres of public land and 339,729 acres of WIHA open to hunters this fall.
Pheasant – Spring breeding populations declined almost 50 percent from 2011 to 2012, reducing fall population potential. Early nesting conditions were decent due to good winter wheat growth, but early wheat harvest and severe heat and drought through the summer reduced populations. While this resulted in a significant drop in pheasant numbers, the area will still have the highest densities of pheasants this fall compared to other areas in the state. Some counties — such as Graham, Rawlins, Decatur, and Sherman — showed the relatively-highest densities of pheasants during summer brood surveys. Much of the cover will be reduced compared to previous years due to drought and resulting emergency haying and grazing in CRP fields. Good hunting opportunities will also be reduced compared to recent years, and harvest will likely be below average.
Quail – Populations in this region have been increasing in recent years although the breeding population had a slight decline. This area is at the extreme northwestern edge of bobwhite range in Kansas, and densities are relatively low compared to central Kansas. Some counties — such as Graham, Rawlins, and Decatur — will provide hunting opportunities for quail.
Prairie Chicken – Prairie chicken populations have expanded in both numbers and range within the region over the past 20 years. The better hunting opportunities will be found in the central and southeastern portions of the region in native prairies and nearby CRP grasslands. Spring lek counts in that portion of the region were slightly depressed from last year and nesting conditions were only fair this year. Extreme drought likely impaired chick survival.
This region has 75,576 acres of public land and 311,182 acres of WIHA open to hunters this fall.
Pheasant – The Smoky Hills breeding population dropped about 40 percent from 2011 to 2012, reducing overall fall population potential. While nesting conditions were fair due to good winter wheat growth, the drought and early wheat harvest impacted the number of young recruited into the fall population. Certain areas had decent brood production, including portions of Mitchell, Rush, Rice, and Cloud counties. Across the region, hunting opportunities will likely be below average and definitely reduced from recent years. CRP was opened to emergency haying and grazing, reducing available cover.
Quail – Breeding populations increased nearly 60 percent from 2011 to 2012, increasing fall population potential. However, drought conditions were severe, likely impairing nesting and brood success. There are reports of fair quail numbers in certain areas throughout the region. Quail populations in northcentral Kansas are naturally spotty due to habitat characteristics. Some areas, such as Cloud County, showed good potential while other areas in the more western edges of the region did not fare as well.
Prairie Chicken – Greater prairie chickens occur throughout the Smoky Hills in large areas of native rangeland and some CRP. This region includes some of the highest densities and greatest hunting opportunities in the state for greater prairie chickens. Spring counts indicated that numbers were stable or slightly reduce from last year. Much of the rangeland cover is significantly reduced due to drought, which likely impaired production, resulting in reduced fall hunting opportunities..
This region has 60,559 acres of public land and 54,170 of WIHA open to hunters this fall.
Pheasant – Spring crow counts this year showed a significant increase in breeding populations of pheasants. While this increase is welcome, this region was nearing all-time lows in 2011. Pheasant densities across the region are still low, especially compared to other areas in western Kansas. Good hunting opportunities will exist in only a few pockets of good habitat.
Quail – Breeding populations stayed relatively the same as last year, and some quail were detected during the summer brood survey. The long-term trend for this region has been declining, largely due to unfavorable weather and degrading habitat. This year saw an increase in populations. Hunting opportunities for quail will be improved this fall compared to recent years in this region. The best areas will likely be in Marshall and Jefferson counties.
Prairie Chickens – Very little prairie chicken range occurs in this region, and opportunities are limited. The best areas are in the western edges of the region, in large areas of native rangeland.
This region has 80,759 acres of public land and 28,047 acres of WIHA open to hunters this fall.
Pheasant – This region is outside the primary pheasant range and has very limited hunting. A few birds can be found in the northwestern portion of the region.
Quail – Breeding populations were relatively stable from 2011 to 2012 for this region although long term trends have been declining. In the last couple years, the quail populations throughout much of the region have been on the increase. Specific counties that showed relatively higher numbers are Coffey, Osage, and Wilson. However, populations remain far below historic levels across the bulk of the region due to extreme habitat degradation.
Prairie Chicken – Greater prairie chickens occur in the central and northwest parts of this region in large areas of native rangeland. Breeding population densities were up nearly 40 percent from last year, and opportunities may increase accordingly. However, populations have been in consistent decline over the long term. Infrequent fire frequency has resulted in woody encroachment of native grasslands in the area, gradually reducing the amount of suitable habitat.
This region has 128,371 acres of public land and 63,069 acres of WIHA open to hunters this fall.
Pheasant – This region is on the eastern edge of pheasant range in Kansas and well outside the primary range. Pheasant densities have always been relatively low throughout the Flint Hills. Spring breeding populations were down nearly 50 percent, and reproduction was limited this summer. The best pheasant hunting will be in the northwestern edge of this region in Marion and Dickinson counties.
Quail – This region contains some of the highest densities of bobwhite in Kansas. The breeding population in this region increased 25 percent compared to 2011, and the long-term trend (since 1998) has been stable do to steadily increasing populations over the last four or five years. High reproductive success was reported in the northern half of this region, and some of the best opportunities for quail hunting will be found in the northern Flint Hills this year. In the south, Cowley County showed good numbers of quail this summer.
Prairie Chickens – The Flint Hills is the largest intact tallgrass prairie left in North America. It has served as a core habitat for greater prairie chickens for many years. Since the early 1980s, inadequate range burning frequencies have consistently reduced nest success in the area, and prairie chicken numbers have been declining as a result. Because of the drought this spring, many areas that are normally burned annually were left unburned this year. This left more residual grass cover for nesting and brood rearing. There are some good reports of prairie chicken broods, and hunting opportunities will likely increase throughout the region this year.
This region has 19,534 acres of public land and 73,341 acres of WIHA open to hunters this fall.
Pheasant – The breeding population declined about 40 percent from 2011 to 2012. Prolonged drought for two years now and very poor vegetation conditions resulted in poor reproductive success this year. All summer indices showed a depressed pheasant population in this region, especially compared to other regions. Some of the relatively better counties in this area will be Reno, Pawnee, and Pratt although these counties have not been immune to recent declines. There will likely few good hunting opportunities this fall.
Quail – The breeding population dropped over 30 percent this year from 2011 although long term trends (since 1998) have been stable in this region. This region generally has some of the highest quail densities in Kansas, but prolonged drought and reduced vegetation have caused significant declines in recent years. Counties such as Reno, Pratt, and Stafford will likely have the best opportunities in the region. While populations may be down compared to recent years, this region will continue to provide fair hunting opportunities for quail.
Prairie Chicken – This region is almost entirely occupied by lesser prairie chickens. The breeding population declined nearly 50 percent from 2011 to 2012. Reproductive conditions were not good for the region due to extreme drought and heat for the last two years, and production was limited. The best hunting opportunities will likely be in the sand prairies south of the Arkansas River.
This region has 2,904 acres of public land and 186,943 acres of WIHA open to hunters this fall.
Pheasant – The breeding population plummeted more than 70 percent in this region from 2011 to 2012. Last year was one of the worst on record for pheasant reproduction. However, last fall there was some carry-over rooster (second-year) from a record high season in 2010. Those carry-over birds are mostly gone now, which will hurt hunting opportunities this fall. Although reproduction was slightly improved from 2011, chick recruitment was still fair to below average this summer due to continued extreme drought conditions. Moreover, there were not enough adult hens in the population yet to make a significant rebound. Generally, hunting opportunity will remain well below average in this region. Haskell and Seward counties showed some improved reproductive success, especially compared to other counties in the region.
Quail – The breeding population in this region tends to be highly variable depending on available moisture and resulting vegetation. The region experienced an increase in breeding populations from 2011 to 2012 although 2011 was a record low for the region. While drought likely held back production, the weather was better than last year, and some reproduction occurred. Indices are still well below average for the region. There will be some quail hunting opportunities in the region although good areas will be sparse.
Prairie Chicken – While breeding populations in the eastern parts of this region were generally stable or increasing, areas of extreme western and southwest portions (Cimarron National Grasslands) saw nearly 30-percent declines last year and 65 percent declines this year. Drought remained extreme in this region, and reproductive success was likely very low. Hunting opportunities in this region will be extremely limited this fall. | <urn:uuid:a611d07f-9067-4341-92f3-f62b82e34e98> | http://www.kdwpt.state.ks.us/index.php/news/Hunting/Upland-Birds/Upland-Bird-Regional-Forecast |
Oil & Natural Gas Projects
Transmission, Distribution, & Refining
Multispectral and Hyperspectral Remote Sensing Techniques for Natural Gas Transmission Infrastructure Systems
The goal is to help maintain the nation's natural gas transmission infrastructure through the timely and effective detection of natural gas leaks through evaluation of geobotanical stress signatures.
The remote sensing techniques being developed employ advanced spectrometer systems that produce visible and near infrared reflected light images with spatial resolution of 1 to 3 meters in 128 wavelength bands. This allows for the discrimination of individual species of plants as well as geological and man-made objects, and permits the detection of biological impacts of methane leaks or seepages in large complicated areas. The techniques employed do not require before-and-after imagery because they use the spatial patterns of plant species and health variations present in a single image to distinguish leaks. Also, these techniques should allow discrimination between the effects of small leaks and the damage caused by human incursion or natural factors such as storm run off, landslides and earthquakes. Because plants in an area can accumulate doses of leaked materials, species spatial patterns can record time-integrated effects of leaked methane. This can be important in finding leaks that would otherwise be hard to detect by direct observation of methane concentrations in the air.
This project is developing remote sensing methods of detecting, discriminating, and mapping the effects of natural gas leaks from underground pipelines. The current focus is on the effects that the increased methane soil concentrations, created by the leaks, will have on plants. These effects will be associated with extreme soil CH4 concentrations, plant sickness, and even death. Similar circumstances have been observed and studied in the effects of excessive CO2soil concentrations at Mammoth Mountain near Mammoth Lakes California, USA. At the Mammoth Mountain site, the large CO2 soil concentrations are due to the volcanic rumblings of the magma still active below Mammoth Mountain. At more subtle levels this research has been able to map, using hyperspectral air borne imagery, the tree plant stress over all of the Mammoth Mountain. These plant stress maps match, and greatly extend into surrounding regions, the on-ground CO2 emission mapping done by the USGS in Menlo Park, California.
In addition, vegetation health mapping along with altered mineralization mapping at Mammoth Mountain does reveal subtle hidden faults. These hidden faults are pathways for potential CO2 leaks, at least near the surface, over the entire region. The methods being developed use airborne hyperspectral and multi-spectral high-resolution imagery and very high resolution (0.6 meter) satellite imagery. The team has identified and worked with commercial providers of both airborne hyperspectral imagery acquisitions and high resolution satellite imagery acquisitions. Both offer competent image data post processing, so that eventually, the ongoing surveillance of pipeline corridors can be contracted for commercially. Current work under this project is focused on detecting and quantifying natural gas pipeline leaks using hyperspectral imagery from airborne or satellite based platforms through evaluation of plant stress.

The use of geobotanical plant stress signatures from hyperspectral imagery potential offers a unique means of detecting and quantifying the existence of natural gas leaks from the U.S. pipeline infrastructure. The method holds the potential to cover large expanses of pipeline with minimal man effort thus reducing the potential likelihood that a leak would go undetected. By increasing the effectiveness and efficiency of leak detection, the amount of gas leaked from a site can be reduced resulting in decreased environmental impact from fugitive emissions of gas, increased safety and reliability of gas delivery and increase in overall available gas; as less product is lost from the lines.
The method chosen for testing these techniques was to image the area surrounding known gas pipeline leaks. After receiving notice and location information for a newly discovered leak from research collaborator Pacific Gas and Electric (PG&E), researchers determined the area above the buried pipeline to be scanned, including some surrounding areas thought to be outside the influence of any methane that might percolate to within root depth of the surface. Flight lines were designed for the airborne acquisition program and researchers used a geographic positioning system (GPS) and digital cameras to visually record the soils, plants, minerals, waters, and manmade objects in the area while the airborne imagery was acquired. After the airborne imagery set for all flight lines was received (including raw data, data corrected to reflectance including atmospheric absorptions, and georectification control files), the data was analyzed using commercial computer software (ENVI) by a team of researchers at University of California, Santa Cruz (UCSC), Lawrence Livermore National Laboratory (LLNL), and one of the acquisition contractors.
- Created an advanced Geographic Information System (GIS) that will be able provide dynamic integration of airborne imagery, satellite imagery, and other GIS information to monitor pipelines for geobotanical leak signatures.
- Used the software to integrate hyperspectral imagery, high resolution satellite imagery, and digital elevation models of the area around a known gas leak to determine if evidence of the leak could be resolved.
- Helped develop hyperspectral imagery payload for use on an unmanned aerial vehicle developed by NASA-Ames.
- Participated in DOE-NETL sponsored natural gas pipeline leak detection demonstration in Casper, Wyoming on September 13-17, 2004. Using both the UAV hyperspectral payload (~1000 ft), and Hyvista hyperspectral platform (~5000 ft) to survey for plant stress.
Researchers used several different routines available within the ENVI program suite to produce “maps” of plant species types, plant health within species types, soil types, soil conditions, water bodies, water contents such as algae or sediments, mineralogy of exposed formations, and manmade objects. These maps were then studied for relative plant health patterns, altered mineral distributions, and other categories. The researchers then returned to the field to verify and further understand the mappings, fine-tune the results, and produce more accurate maps. Since the maps are georectified and the pixel size is 3 meters, individual objects can all be located using the maps and a handheld GPS.
These detailed maps show areas of existing anomalous conditions such as plant kills and linear species modifications caused by subtle hidden faults, modifications of the terrain due to pipeline work or encroachment. They are also the “baseline” that can be used to chart any future changes by re-imaging the area routinely to monitor and document any effects caused by significant methane leakage.
The sensors used for image acquisition are hyperspectral scanners, one of which provides 126 bands across the reflective solar wavelength region of 0.45 – 2.5 nm with contiguous spectral coverage (except in the atmospheric water vapor bands) and bandwidths between 15 – 20 nm. This sensor operates on a 3-axis gyro-stabilized platform to minimize image distortion due to aircraft motion and provides a signal to noise ratio >500:1. Geo-location and image geo-coding is achieved with an-on board Differential GPS (DGPS) and an integrated IMU (inertial monitoring unit).
During a DOE – NETL sponsored natural gas leak detection demonstration at the National Petroleum Reserve 3 (NPR3) site of the Rocky Mountain Oilfield Testing Center (RMOTC) outside of Casper, Wyoming, the project utilized hyperspectral imaging of vegetation to sense plant stress related to the presence of natural gas on a simulated pipeline using actual natural gas releases. The spectral signature of sunlight reflected from vegetation was used to determine vegetation health. Two different platforms were used for imaging the virtual pipeline path: a Twin Otter aircraft flying at an altitude of about 5,000 feet above ground level that imaged the entire site in strips, and an unmanned autonomous vehicle (UAV) flying at an altitude of approximately 1,000 feet above ground level that imaged an area surrounding the virtual pipeline.
The manned hyperspectral imaging took place on two days. Wednesday, September 9 and Wednesday, September 15. The underground leaks were started on August 30. This was done to allow time for the methane from the leaks to saturate the soils and produce plant stress by excluding oxygen from the plant root systems. On both days, the entire NPR3-RMOTC site was successfully imaged.
At that time of year, the vegetation at NPR3-RMOTC was largely in hibernation. The exception was in the gullies where there was some moisture. Therefore, the survey looked for unusually stressed plant “patches” in the gullies as possible leak points. Several spots were found in the hyperspectral imagery that had the spectral signature typical of sick vegetation that were several pixels in diameter in locations in the gullies or ravines along the virtual pipeline route. Due to the limited vegetation along the test route the successful detection of natural gas leaks through imaging of plant stress was limited in success. The technique did demonstrate an ability to show plant stress in areas near leak sites but was less successful in determining general leak severity based on those results. In areas with much denser vegetation coverage and less dormant plant life the method still shows promise.

Notes on the Bible, by Albert Barnes, , at sacred-texts.com
Now the word of the Lord - , literally, "And, ..." This is the way in which the several inspired writers of the Old Testament mark that what it was given them to write was united onto those sacred books which God had given to others to write, and it formed with them one continuous whole. The word, "And," implies this. It would do so in any language, and it does so in Hebrew as much as in any other. As neither we, nor any other people, would, without any meaning, use the word, And, so neither did the Hebrews. It joins the four first books of Moses together; it carries on the history through Joshua, Judges, the Books of Samuel and of the Kings. After the captivity, Ezra and Nehemiah begin again where the histories before left off; the break of the captivity is bridged over; and Ezra, going back in mind to the history of God's people before the captivity, resumes the history, as if it had been of yesterday, "And in the first year of Cyrus." It joins in the story of the Book of Ruth before the captivity, and that of Esther afterward. At times, even prophets employ it, in using the narrative form of themselves, as Ezekiel, "and it was in the thirtieth year, in the fourth month, in the fifth day of the month, and I was in the captivity by the river of Chebar, the heavens opened and I saw." If a prophet or historian wishes to detach his prophecy or his history, he does so; as Ezra probably began the Book of Chronicles anew from Adam, or as Daniel makes his prophecy a whole by itself. But then it is the more obvious that a Hebrew prophet or historian, when he does begin with the word, "And," has an object in so beginning; he uses an universal word of all languages in its uniform meaning in all language, to join things together.
And yet more precisely; this form, "and the word of the Lord came to - saying," occurs over and over again, stringing together the pearls of great price of God's revelations, and uniting this new revelation to all those which had preceded it. The word, "And," then joins on histories with histories, revelations with revelations, uniting in one the histories of God's works and words, and blending the books of Holy Scripture into one divine book.
But the form of words must have suggested to the Jews another thought, which is part of our thankfulness and of our being Act 11:18, "then to the Gentiles also hath God given repentance unto life." The words are the self-same familiar words with which some fresh revelation of God's will to His people had so often been announced. Now they are prefixed to God's message to the pagan, and so as to join on that message to all the other messages to Israel. Would then God deal thenceforth with the pagan as with the Jews? Would they have their prophets? Would they be included in the one family of God? The mission of Jonah in itself was an earnest that they would, for God. Who does nothing fitfully or capriciously, in that He had begun, gave an earnest that He would carry on what He had begun. And so thereafter, the great prophets, Isaiah, Jeremiah, Ezekiel, were prophets to the nations also; Daniel was a prophet among them, to them as well as to their captives.
But the mission of Jonah might, so far, have been something exceptional. The enrolling his book, as an integral part of the Scriptures, joining on that prophecy to the other prophecies to Israel, was an earnest that they were to be parts of one system. But then it would be significant also, that the records of God's prophecies to the Jews, all embodied the accounts of their impenitence. Here is inserted among them an account of God's revelation to the pagan, and their repentance. "So many prophets had been sent, so many miracles performed, so often had captivity been foreannounced to them for the multitude of their sins. and they never repented. Not for the reign of one king did they cease from the worship of the calves; not one of the kings of the ten tribes departed from the sins of Jeroboam? Elijah, sent in the Word and Spirit of the Lord, had done many miracles, yet obtained no abandonment of the calves. His miracles effected this only, that the people knew that Baal was no god, and cried out, "the Lord He is the God." Elisha his disciple followed him, who asked for a double portion of the Spirit of Elijah, that he might work more miracles, to bring back the people.
He died, and, after his death as before it, the worship of the calves continued in Israel. The Lord marveled and was weary of Israel, knowing that if He sent to the pagan they would bear, as he saith to Ezekiel. To make trial of this, Jonah was chosen, of whom it is recorded in the Book of Kings that he prophesied the restoration of the border of Israel. When then he begins by saying, "And the word of the Lord came to Jonah," prefixing the word "And," he refers us back to those former things, in this meaning. The children have not hearkened to what the Lord commanded, sending to them by His servants the prophets, but have hardened their necks and given themselves up to do evil before the Lord and provoke Him to anger; "and" therefore "the word of the Lord came to Jonah, saying, Arise and go to Nineveh that great city, and preach unto her," that so Israel may be shewn, in comparison with the pagan, to be the more guilty, when the Ninevites should repent, the children of Israel persevered in unrepentance."
Jonah the son of Amittai - Both names occur here only in the Old Testament, Jonah signifies "Dove," Amittai, "the truth of God." Some of the names of the Hebrew prophets so suit in with their times, that they must either have been given them propheticly, or assumed by themselves, as a sort of watchword, analogous to the prophetic names, given to the sons of Hosea and Isaiah. Such were the names of Elijah and Elisha, "The Lord is my God," "my God is salvation." Such too seems to be that of Jonah. The "dove" is everywhere the symbol of "mourning love." The side of his character which Jonah records is that of his defect, his want of trust in God, and so his unloving zeal against those, who were to be the instruments of God against his people. His name perhaps preserves that character by which he willed to be known among his people, one who moaned or mourned over them.
Arise, go to Nineveh, that great city - The Assyrian history, as far as it has yet been discovered, is very bare of events in regard to this period. We have as yet the names of three kings only for 150 years. But Assyria, as far as we know its history, was in its meridian. Just before the time of Jonah, perhaps ending in it, were the victorious reigns of Shalmanubar and Shamasiva; after him was that of Ivalush or Pul, the first aggressor upon Israel. It is clear that this was a time Of Assyrian greatness: since God calls it "that great city," not in relation to its extent only, but its power. A large weak city would not have been called a "great city unto God" Jon 3:3.
And cry against it - The substance of that cry is recorded afterward, but God told to Jonah now, what message he was to cry aloud to it. For Jonah relates afterward, how he expostulated now with God, and that his expostulation was founded on this, that God was so merciful that He would not fulfill the judgment which He threatened. Faith was strong in Jonah, while, like Apostles "the sons of thunder," before the Day of Pentecost, he knew not" what spirit he was of." Zeal for the people and, as he doubtless thought, for the glory of God, narrowed love in him. He did not, like Moses, pray Exo 32:32, "or else blot me also out of Thy book," or like Paul, desire even to be "an anathema from Christ" Rom 9:3 for his people's sake, so that there might be more to love his Lord. His zeal was directed, like that of the rebuked Apostles, against others, and so it too was rebuked. But his faith was strong. He shrank back from the office, as believing, not as doubting, the might of God. He thought nothing of preaching, amid that multitude of wild warriors, the stern message of God. He was willing, alone, to confront the violence of a city of 600,000, whose characteristic was violence. He was ready, at God's bidding, to enter what Nahum speaks of as a den of lions Nah 2:11-12; "The dwelling of the lions and the feeding-place of the young lions, where the lion did tear in pieces enough for his whelps, and strangled for his lionesses." He feared not the fierceness of their lion-nature, but God's tenderness, and lest that tenderness should be the destruction of his own people.
Their wickedness is come up before Me - So God said to Cain, Gen 4:10. "The voice of thy brother's blood crieth unto Me from the ground:" and of Sodom Gen 18:20 :21, "The cry of Sodom and Gomorrah is great, because their sin is very grievous; the cry of it is come up unto Me." The "wickedness" is not the mere mass of human sin, of which it is said Jo1 5:19, "the whole world lieth in wickedness," but evil-doing toward others. This was the cause of the final sentence on Nineveh, with which Nahum closes his prophecy, "upon whom hath not thy wickedness passed continually?" It bad been assigned as the ground of the judgment on Israel through Nineveh Hos 10:14-15. "So shall Bethel do unto you, on account of the wickedness of your wickedness." It was the ground of the destruction by the flood Gen 6:5. "God saw that the wickedness of man was great upon the earth." God represents Himself, the Great Judge, as sitting on His Throne in heaven, Unseen but All-seeing, to whom the wickedness and oppressiveness of man against man "goes up," appealing for His sentence against the oppressor. The cause seems ofttimes long in pleading. God is long-suffering with the oppressor too, that if so be, he may repent. So would a greater good come to the oppressed also, if the wolf became a lamb. But meanwhile, " every iniquity has its own voice at the hidden judgment seat of God." Mercy itself calls for vengeance on the unmerciful.
But (And) Jonah rose up to flee ... from the presence of the Lord - literally "from being before the Lord." Jonah knew well, that man could not escape from the presence of God, whom he knew as the Self-existing One, He who alone is, the Maker of heaven, earth and sea. He did not "flee" then "from His presence," knowing well what David said Psa 139:7, Psa 139:9-10, "whither shall I go from Thy Spirit, or whither shall I flee from Thy presence? If I take the wings of the morning, and dwell in the uttermost parts of the sea, even there shall Thy hand lead me and Thy right hand shall hold me." Jonah fled, not from God's presence, but from standing before him, as His servant and minister. He refused God's service, because, as he himself tells God afterward Jon 4:2, he knew what it would end in, and he misliked it.
So he acted, as people often do, who dislike God's commands. He set about removing himself as far as possible from being under the influence of God, and from the place where he "could" fulfill them. God commanded him to go to Nineveh, which lay northeast from his home; and he instantly set himself to flee to the then furthermost west. Holy Scripture sets the rebellion before us in its full nakedness. "The word of the Lord came unto Jonah, go to Nineveh, and Jonah rose up;" he did something instantly, as the consequence of God's command. He "rose up," not as other prophets, to obey, but to disobey; and that, not slowly nor irresolutely, but "to flee, from" standing "before the Lord." He renounced his office. So when our Lord came in the flesh, those who found what He said to be "hard sayings," went away from Him, "and walked no more with Him" Joh 6:66. So the rich "young man went away sorrowful Mat 19:22, for he had great possessions."
They were perhaps afraid of trusting themselves in His presence; or they were ashamed of staying there, and not doing what He said. So men, when God secretly calls them to prayer, go and immerse themselves in business; when, in solitude, He says to their souls something which they do not like, they escape His Voice in a throng. If He calls them to make sacrifices for His poor, they order themselves a new dress or some fresh sumptuousness or self-indulgence; if to celibacy, they engage themselves to marry immediately; or, contrariwise, if He calls them not to do a thing, they do it at once, to make an end of their struggle and their obedience; to put obedience out of their power; to enter themselves on a course of disobedience. Jonah, then, in this part of his history, is the image of those who, when God calls them, disobey His call, and how He deals with them, when he does not abandon them. He lets them have their way for a time, encompasses them with difficulties, so that they shall "flee back from God displeased to God appeased."
"The whole wisdom, the whole bliss, the whole of man lies in this, to learn what God wills him to do, in what state of life, calling, duties, profession, employment, He wills him to serve Him." God sent each one of us into the world, to fulfill his own definite duties, and, through His grace, to attain to our own perfection in and through fulfilling them. He did not create us at random, to pass through the world, doing whatever self-will or our own pleasure leads us to, but to fulfill His will. This will of His, if we obey His earlier calls, and seek Him by prayer, in obedience, self-subdual, humility, thoughtfulness, He makes known to each by His own secret drawings, and, in absence of these, at times by His Providence or human means. And then , "to follow Him is a token of predestination." It is to place ourselves in that order of things, that pathway to our eternal mansion, for which God created us, and which God created for us.
So Jesus says Joh 10:27-28, "My sheep hear My voice and I know them, and they follow Me, and I give unto them eternal life, and they shall never perish, neither shall any man pluck them out of My Hand." In these ways, God has foreordained for us all the graces which we need; in these, we shall be free from all temptations which might be too hard for us, in which our own special weakness would be most exposed. Those ways, which people choose out of mere natural taste or fancy, are mostly those which expose them to the greatest peril of sin and damnation. For they choose them, just because such pursuits flatter most their own inclinations, and give scope to their natural strength and their moral weakness. So Jonah, disliking a duty, which God gave him to fulfill, separated himself from His service, forfeited his past calling, lost, as far as in him lay, his place among "the goodly fellowship of the prophets," and, but for God's overtaking grace, would have ended his days among the disobedient. As in Holy Scripture, David stands alone of saints, who had been after their calling, bloodstained; as the penitent robber stands alone converted in death; as Peter stands singly, recalled after denying his Lord; so Jonah stands, the one prophet, who, having obeyed and then rebelled, was constrained by the overpowering providence and love of God, to return and serve Him.
"Being a prophet, Jonah could not be ignorant of the mind of God, that, according to His great Wisdom and His unsearchable judgments and His untraceable and incomprehensible ways, He, through the threat, was providing for the Ninevites that they should not suffer the things threatened. To think that Jonah hoped to hide himself in the sea and elude by flight the great Eye of God, were altogether absurd and ignorant, which should not be believed, I say not of a prophet, but of no other sensible person who had any moderate knowledge of God and His supreme power. Jonah knew all this better than anyone, that, planning his flight, he changed his place, but did not flee God. For this could no man do, either by hiding himself in the bosom of the earth or depths of the sea or ascending (if possible) with wings into the air, or entering the lowest hell, or encircled with thick clouds, or taking any other counsel to secure his flight.
This, above all things and alone, can neither be escaped nor resisted, God. When He willeth to hold and grasp in His Hand, He overtaketh the swift, baffleth the intelligent, overthroweth the strong, boweth the lofty, tameth rashness, subdueth might. He who threatened to others the mighty Hand of God, was not himself ignorant of nor thought to flee, God. Let us not believe this. But since he saw the fall of Israel and perceived that the prophetic grace would pass over to the Gentiles, he withdrew himself from the office of preaching, and put off the command." "The prophet knoweth, the Holy Spirit teaching him, that the repentance of the Gentiles is the ruin of the Jews. A lover then of his country, he does not so much envy the deliverance of Nineveh, as will that his own country should not perish. - Seeing too that his fellow-prophets are sent to the lost sheep of the house of Israel, to excite the people to repentance, and that Balaam the soothsayer too prophesied of the salvation of Israel, he grieveth that he alone is chosen to be sent to the Assyrians, the enemies of Israel, and to that greatest city of the enemies where was idolatry and ignorance of God. Yet more he feared lest they, on occasion of his preaching, being converted to repentance, Israel should be wholly forsaken. For he knew by the same Spirit whereby the preaching to the Gentiles was entrusted to him, that the house of Israel would then perish; and he feared that what was at one time to be, should take place in his own time." "The flight of the prophet may also be referred to that of man in general who, despising the commands of God, departed from Him and gave himself to the world, where subsequently, through the storms of ill and the wreck of the whole world raging against him, he was compelled to feel the presence of God, and to return to Him whom he had fled. Whence we understand, that those things also which men think for their good, when against the will of God, are turned to destruction; and help not only does not benefit those to whom it is given, but those too who give it, are alike crushed. As we read that Egypt was conquered by the Assyrians, because it helped Israel against the will of God. The ship is emperiled which had received the emperiled; a tempest arises in a calm; nothing is secure, when God is against us."
Tarshish - , named after one of the sons of Javan, Gen 10:4. was an ancient merchant city of Spain, once proverbial for its wealth (Psa 72:10. Strabo iii. 2. 14), which supplied Judaea with silver Jer 10:9, Tyre with "all manner of riches," with iron also, tin, lead. Eze 27:12, Eze 27:25. It was known to the Greeks and Romans, as (with a harder pronunciation) Tartessus; but in our first century, it had either ceased to be, or was known under some other name. Ships destined for a voyage, at that time, so long, and built for carrying merchandise, were naturally among the largest then constructed. "Ships of Tarshish" corresponded to the "East-Indiamen" which some of us remember. The breaking of "ships of Tarshish by the East Wind" Psa 48:7 is, on account of their size and general safety, instanced as a special token of the interposition of God.
And went down to Joppa - Joppa, now Jaffa (Haifa), was the one well-known port of Israel on the Mediterranean. There the cedars were brought from Lebanon for both the first and second temple Ch2 3:16; Ezr 2:7. Simon the Maccabee (1 Macc. 14:5) "took it again for a haven, and made an entrance to the isles of the sea." It was subsequently destroyed by the Romans, as a pirate-haven. (Josephus, B. J. iii. 9. 3, and Strabo xvi. 2. 28.) At a later time, all describe it as an unsafe haven. Perhaps the shore changed, since the rings, to which Andromeda was tabled to have been fastened, and which probably were once used to moor vessels, were high above the sea. Perhaps, like the Channel Islands, the navigation was safe to those who knew the coast, unsafe to others. To this port Jonah "went down" from his native country, the mountain district of Zabulon. Perhaps it was not at this time in the hands of Israel. At least, the sailors were pagan. He "went down," as the man who fell among the thieves, is said to "have gone down from Jerusalem to Jericho." Luk 10:30. He "went down" from the place which God honored by His presence and protection.
And he paid the fare thereof - Jonah describes circumstantially, how he took every step to his end. He went down, found a strongly built ship going where he wished, paid his fare, embarked. He seemed now to have done all. He had severed himself from the country where his office lay. He had no further step to take. Winds and waves would do the rest. He had but to be still. He went, only to be brought back again.
"Sin brings our soul into much senselessness. For as those overtaken by heaviness of head and drunkenness, are borne on simply and at random, and, be there pit or precipice or whatever else below them, they fall into it unawares; so too, they who fall into sin, intoxicated by their desire of the object, know not what they do, see nothing before them, present or future. Tell me, Fleest thou the Lord? Wait then a little, and thou shalt learn from the event, that thou canst not escape the hands of His servant, the sea. For as soon as he embarked, it too roused its waves and raised them up on high; and as a faithful servant, finding her fellow-slave stealing some of his master's property, ceases not from giving endless trouble to those who take him in, until she recover him, so too the sea, finding and recognizing her fellow-servant, harasses the sailors unceasingly, raging, roaring, not dragging them to a tribunal but threatening to sink the vessel with all its unless they restore to her, her fellow-servant."
"The sinner "arises," because, will he, nill he, toil he must. If he shrinks from the way of God, because it is hard, he may not yet be idle. There is the way of ambition, of covetousness, of pleasure, to be trodden, which certainly are far harder. 'We wearied ourselves (Wisdom 5:7),' say the wicked, 'in the way of wickedness and destruction, yea, we have gone through deserts where there lay no way; but the way of the Lord we have not known.' Jonah would not arise, to go to Nineveh at God's command; yet he must needs arise, to flee to Tarshish from before the presence of God. What good can he have who fleeth the Good? what light, who willingly forsaketh the Light? "He goes down to Joppa." Wherever thou turnest, if thou depart from the will of God, thou goest down. Whatever glory, riches, power, honors, thou gainest, thou risest not a whit; the more thou advancest, while turned from God, the deeper and deeper thou goest down. Yet all these things are not had, without paying the price. At a price and with toil, he obtains what he desires; he receives nothing gratis, but, at great price purchases to himself storms, griefs, peril. There arises a great tempest in the sea, when various contradictory passions arise in the heart of the sinner, which take from him all tranquility and joy. There is a tempest in the sea, when God sends strong and dangerous disease, whereby the frame is in peril of being broken. There is a tempest in the sea, when, thro' rivals or competitors for the same pleasures, or the injured, or the civil magistrate, his guilt is discovered, he is laden with infamy and odium, punished, withheld from his wonted pleasures. Psa 107:23-27. "They who go down to the sea of this world, and do business in mighty waters - their soul melteth away because of trouble; they reel to and fro and stagger like a drunken man, and all their wisdom is swallowed up."
But (And) the Lord sent out - (literally 'cast along'). Jonah had done his all. Now God's part began. This He expresses by the word, "And." Jonah took "his" measures, "and" now God takes "His." He had let him have his way, as He often deals with those who rebel against Him. He lets them have their way up to a certain point. He waits, in the tranquility of His Almightiness, until they have completed their preparations; and then, when man has ended, He begins, that man may see the more that it is His doing . "He takes those who flee from Him in their flight, the wise in their counsels, sinners in their conceits and sins, and draws them back to Himself and compels them to return. Jonah thought to find rest in the sea, and lo! a tempest." Probably, God summoned back Jonah, as soon as he had completed all on his part, and sent the tempest, soon after he left the shore.
At least, such tempests often swept along that shore, and were known by their own special name, like the Euroclydon off Crete. Jonah too alone had gone down below deck to sleep, and, when the storm came, the mariners thought it possible to put back. Josephus says of that shore, "Joppa having by nature no haven, for it ends in a rough shore, mostly abrupt, but for a short space having projections, i. e., deep rocks and cliffs advancing into the sea, inclining on either side toward each other (where the traces of the chains of Andromeda yet shown accredit the antiquity of the fable,) and the north wind beating right on the shore, and dashing the high waves against the rocks which receive them, makes the station there a harborless sea. As those from Joppa were tossing here, a strong wind (called by those who sail here, the black north wind) falls upon them at daybreak, dashing straightway some of the ships against each other, some against the rocks, and some, forcing their way against the waves to the open sea, (for they fear the rocky shore ...) the breakers towering above them, sank."
The ship was like - (literally 'thought') To be broken Perhaps Jonah means by this very vivid image to exhibit the more his own dullness. He ascribes, as it were, to the ship a sense of its own danger, as she heaved and rolled and creaked and quivered under the weight of the storm which lay on her, and her masts groaned, and her yard-arms shivered. To the awakened conscience everything seems to have been alive to God's displeasure, except itself.
And cried, every man unto his God - They did what they could. "Not knowing the truth, they yet know of a Providence, and, amid religious error, know that there is an Object of reverence." In ignorance they had received one who offended God. And now God, "whom they ignorantly worshiped" Act 17:23, while they cried to the gods, who, they thought, disposed of them, heard them. They escaped with the loss of their wares, but God saved their lives and revealed Himself to them. God hears ignorant prayer, when ignorance is not willful and sin.
To lighten it of them - , literally "to lighten from against them, to lighten" what was so much "against them," what so oppressed them. "They thought that the ship was weighed down by its wonted lading, and they knew not that the whole weight was that of the fugitive prophet." "The sailors cast forth their wares," but the ship was not lightened. For the whole weight still remained, the body of the prophet, that heavy burden, not from the nature of the body, but from the burden of sin. For nothing is so onerous and heavy as sin and disobedience. Whence also Zechariah Zac 5:7 represented it under the image of lead. And David, describing its nature, said Psa 38:4, "my wickednesses are gone over my head; as a heavy burden they are too heavy for me." And Christ cried aloud to those who lived in many sins, Mat 11:28. "Come unto Me, all ye that labor and are heavy-laden, and I will refresh you."
Jonah was gone down - , probably before the beginning of the storm, not simply before the lightening of the vessel. He could hardly have fallen asleep "then." A pagan ship was a strange place for a prophet of God, not as a prophet, but as a fugitive; and so, probably, ashamed of what he had completed, he had withdrawn from sight and notice. He did not embolden himself in his sin, but shrank into himself. The conscience most commonly awakes, when the sin is done. It stands aghast as itself; but Satan, if he can, cuts off its retreat. Jonah had no retreat now, unless God had made one.
And was fast asleep - The journey to Joppa had been long and hurried; he had "fled." Sorrow and remorse completed what fatigue began. Perhaps he had given himself up to sleep, to dull his conscience. For it is said, "he lay down and was fast asleep." Grief produces sleep; from where it is said of the apostles in the night before the Lord's Passion, when Jesus "rose up from prayer and was come to His disciples, He found them sleeping for sorrow" Luk 22:45 . "Jonah slept heavily. Deep was the sleep, but it was not of pleasure but of grief; not of heartlessness, but of heavy-heartedness. For well-disposed servants soon feel their sins, as did he. For when the sin has been done, then he knows its frightfulness. For such is sin. When born, it awakens pangs in the soul which bare it, contrary to the law of our nature. For so soon as we are born, we end the travail-pangs; but sin, so soon as born, rends with pangs the thoughts which conceived it." Jonah was in a deep sleep, a sleep by which he was fast held and bound; a sleep as deep as that from which Sisera never woke. Had God allowed the ship to sink, the memory of Jonah would have been that of the fugitive prophet. As it is, his deep sleep stands as an image of the lethargy of sin . "This most deep sleep of Jonah signifies a man torpid and slumbering in error, to whom it sufficed not to flee from the face of God, but his mind, drowned in a stupor and not knowing the displeasure of God, lies asleep, steeped in security."
What meanest thou? - or rather, "what aileth thee?" (literally "what is to thee?") The shipmaster speaks of it (as it was) as a sort of disease, that he should be thus asleep in the common peril. "The shipmaster," charged, as he by office was, with the common weal of those on board, would, in the common peril, have one common prayer. It was the prophet's office to call the pagan to prayers and to calling upon God. God reproved the Scribes and Pharisees by the mouth of the children who "cried Hosanna" Mat 21:15; Jonah by the shipmaster; David by Abigail; Sa1 25:32-34; Naaman by his servants. Now too he reproves worldly priests by the devotion of laymen, sceptic intellect by the simplicity of faith.
If so be that God will think upon us - , (literally "for us") i. e., for good; as David says, Psa 40:17. "I am poor and needy, the Lord thinketh upon" (literally "for") "me." Their calling upon their own gods had failed them. Perhaps the shipmaster had seen something special about Jonah, his manner, or his prophet's garb. He does not only call Jonah's God, "thy" God, as Darius says to Daniel "thy God" Dan 6:20, but also "the God," acknowledging the God whom Jonah worshiped, to be "the God." It is not any pagan prayer which he asks Jonah to offer. It is the prayer of the creature in its need to God who can help; but knowing its own ill-desert, and the separation between itself and God, it knows not whether He will help it. So David says Psa 25:7, "Remember not the sins of my youth nor my transgressions; according to Thy mercy remember Thou me for Thy goodness' sake, O Lord."
"The shipmaster knew from experience, that it was no common storm, that the surges were an infliction borne down from God, and above human skill, and that there was no good in the master's skill. For the state of things needed another Master who ordereth the heavens, and craved the guidance from on high. So then they too left oars, sails, cables, gave their hands rest from rowing, and stretched them to heaven and called on God."
Come, and let us cast lots - Jonah too had probably prayed, and his prayers too were not heard. Probably, too, the storm had some unusual character about it, the suddenness with which it burst upon them, its violence, the quarter from where it came, its whirlwind force . "They knew the nature of the sea, and, as experienced sailors, were acquainted with the character of wind and storm, and had these waves been such as they had known before, they would never have sought by lot for the author of the threatened wreck, or, by a thing uncertain, sought to escape certain peril." God, who sent the storm to arrest Jonah and to cause him to be cast into the sea, provided that its character should set the mariners on divining, why it came. Even when working great miracles, God brings about, through man, all the forerunning events, all but the last act, in which He puts forth His might. As, in His people, he directed the lot to fall upon Achan or upon Jonathan, so here He overruled the lots of the pagan sailors to accomplish His end. " We must not, on this precedent, immediately trust in lots, or unite with this testimony that from the Acts of the Apostles, when Matthias was by lot elected to the apostolate, since the privileges of individuals cannot form a common law." "Lots," according to the ends for which they were cast, were for:
i) The lot for dividing is not wrong if not used,
1) "without any necessity, for this would be to tempt God:"
2) "if in case of necessity, not without reverence of God, as if Holy Scripture were used for an earthly end," as in determining any secular matter by opening the Bible:
3) for objects which ought to be decided otherwise, (as, an office ought to be given to the fittest:)
4) in dependence upon any other than God Pro 16:33. "The lot is cast into the lap, but the whole disposing of it is the Lord's." So then they are lawful "in secular things which cannot otherwise be conveniently distributed," or when there is no apparent reason why, in any advantage or disadvantage, one should be preferred to another." Augustine even allows that, in a time of plague or persecution, the lot might be cast to decide who should remain to administer the sacraments to the people, lest, on the one side, all should be taken away, or, on the other, the Church be deserted.
ii.) The lot for consulting, i. e., to decide what one should do, is wrong, unless in a matter of mere indifference, or under inspiration of God, or in some extreme necessity where all human means fail.
iii.) The lot for divining, i. e., to learn truth, whether of things present or future, of which we can have no human knowledge, is wrong, except by direct inspiration of God. For it is either to tempt God who has not promised so to reveal things, or, against God, to seek superhuman knowledge by ways unsanctioned by Him. Satan may readily mix himself unknown in such inquiries, as in mesmerism. Forbidden ground is his own province.
God overruled the lot in the case of Jonah, as He did the sign which the Philistines sought . "He made the heifers take the way to Bethshemesh, that the Philistines might know that the plague came to them, not by chance, but from Hilmself" . "The fugitive (Jonah) was taken by lot, not by any virtue of the lots, especially the lots of pagan, but by the will of Him who guided the uncertain lots" "The lot betrayed the culprit. Yet not even thus did they cast him over; but, even while such a tumult and storm lay on them, they held, as it were, a court in the vessel, as though in entire peace, and allowed him a hearing and defense, and sifted everything accurately, as men who were to give account of their judgment. Hear them sifting all as in a court - The roaring sea accused him; the lot convicted and witnessed against him, yet not even thus did they pronounce against him - until the accused should be the accuser of his own sin. The sailors, uneducated, untaught, imitated the good order of courts. When the sea scarcely allowed them to breathe, whence such forethought about the prophet? By the disposal of God. For God by all this instructed the prophet to be humane and mild, all but saying aloud to him; 'Imitate these uninstructed sailors. They think not lightly of one soul, nor are unsparing as to one body, thine own. But thou, for thy part, gavest up a whole city with so many myriads. They, discovering thee to be the cause of the evils which befell them, did not even thus hurry to condemn thee. Thou, having nothing whereof to accuse the Ninevites, didst sink and destroy them. Thou, when I bade thee go and by thy preaching call them to repentance, obeyedst not; these, untaught, do all, compass all, in order to recover thee, already condemned, from punishment.'"
Tell us, for whose cause - Literally "for what to whom." It may be that they thought that Jonah had been guilty toward some other. The lot had pointed him out. The mariners, still fearing to do wrong, ask him thronged questions, to know why the anger of God followed him; "what" hast thou done "to whom?" "what thine occupation?" i. e., either his ordinary occupation, whether it was displeasing to God? or this particular business in which he was engaged, and for which he had come on board. Questions so thronged have been admired in human poetry, Jerome says. For it is true to nature. They think that some one of them will draw forth the answer which they wish. It may be that they thought that his country, or people, or parents, were under the displeasure of God. But perhaps, more naturally, they wished to "know all about him," as people say. These questions must have gone home to Jonah's conscience. "What is thy business?" The office of prophet which he had left. "Whence comest thou?" From standing before God, as His minister. "What thy country? of what people art thou?" The people of God, whom he had quitted for pagan; not to win them to God, as He commanded; but, not knowing what they did, to abet him in his flight.
What is thine occupation? - They should ask themselves, who have Jonah's office to speak in the name of God, and preach repentance . "What should be thy business, who hast consecrated thyself wholly to God, whom God has loaded with daily benefits? who approachest to Him as to a Friend? "What is thy business?" To live for God, to despise the things of earth, to behold the things of heaven," to lead others heavenward.
Jonah answers simply the central point to which all these questions tended:
I am an Hebrew - This was the name by which Israel was known to foreigners. It is used in the Old Testament, only when they are spoken of by foreigners, or speak of themselves to foreigners, or when the sacred writers mention them in contrast with foreigners . So Joseph spoke of his land Gen 40:15, and the Hebrew midwives Exo 1:19, and Moses' sister Exo 2:7, and God in His commission to Moses Exo 3:18; Exo 7:16; Exo 9:1 as to Pharaoh, and Moses in fulfilling it Exo 5:3. They had the name, as having passed the River Euphrates, "emigrants." The title might serve to remind themselves, that they were "strangers" and "pilgrims," Heb 11:13. whose fathers had left their home at God's command and for God , "passers by, through this world to death, and through death to immortality."
And I fear the Lord - , i. e., I am a worshiper of Him, most commonly, one who habitually stands in awe of Him, and so one who stands in awe of sin too. For none really fear God, none fear Him as sons, who do not fear Him in act. To be afraid of God is not to fear Him. To be afraid of God keeps men away from God; to fear God draws them to Him. Here, however, Jonah probably meant to tell them, that the Object of his fear and worship was the One Self-existing God, He who alone is, who made all things, in whose hands are all things. He had told them before, that he had fled "from being before Yahweh." They had not thought anything of this, for they thought of Yahweh, only as the God of the Jews. Now he adds, that He, Whose service he had thus forsaken, was "the God of heaven, Who made the sea and dry land," that sea, whose raging terrified them and threatened their lives. The title, "the God of heaven," asserts the doctrine of the creation of the heavens by God, and His supremacy.
Hence, Abraham uses it to his servant Gen 24:7, and Jonah to the pagan mariners, and Daniel to Nebuchadnezzar Dan 2:37, Dan 2:44; and Cyrus in acknowledging God in his proclamation Ch2 36:23; Ezr 1:2. After his example, it is used in the decrees of Darius Ezr 6:9-10 and Artaxerxes Ezr 7:12, Ezr 7:21, Ezr 7:23, and the returned exiles use it in giving account of their building the temple to the Governor Ezr 5:11-12. Perhaps, from the habit of contact with the pagan, it is used once by Daniel Dan 2:18 and by Nehemiah Neh 1:4-5; Neh 2:4, Neh 2:20. Melchizedek, not perhaps being acquainted with the special name, Yahweh, blessed Abraham in the name of "God, the Possessor" or "Creator of heaven and earth" Gen 14:19, i. e., of all that is. Jonah, by using it, at once taught the sailors that there is One Lord of all, and why this evil had fallen on them, because they had himself with them, the renegade servant of God. "When Jonah said this, he indeed feared God and repented of his sin. If he lost filial fear by fleeing and disobeying, he recovered it by repentance."
Then were the men exceedingly afraid - Before, they had feared the tempest and the loss of their lives. Now they feared God. They feared, not the creature but the Creator. They knew that what they had feared was the doing of His Almightiness. They felt how awesome a thing it was to be in His Hands. Such fear is the beginning of conversion, when people turn from dwelling on the distresses which surround them, to God who sent them.
Why hast thou done this? - They are words of amazement and wonder. Why hast thou not obeyed so great a God, and how thoughtest thou to escape the hand of the Creator ? "What is the mystery of thy flight? Why did one, who feared God and had revelations from God, flee, sooner than go to fulfill them? Why did the worshiper of the One true God depart from his God?" "A servant flee from his Lord, a son from his father, man from his God!" The inconsistency of believers is the marvel of the young Christian, the repulsion of those without, the hardening of the unbeliever. If people really believed in eternity, how could they be thus immersed in things of time? If they believed in hell, how could they so hurry there? If they believed that God died for them, how could they so requite Him? Faith without love, knowledge without obedience, conscious dependence and rebellion, to be favored by God yet to despise His favor, are the strangest marvels of this mysterious world.
All nature seems to cry out to and against the unfaithful Christian, "why hast thou done this?" And what a why it is! A scoffer has recently said so truthfully : "Avowed scepticism cannot do a tenth part of the injury to practical faith, that the constant spectacle of the huge mass of worldly unreal belief does." It is nothing strange, that the world or unsanctified intellect should reject the Gospel. It is a thing of course, unless it be converted. But, to know, to believe, and to DISOBEY! To disobey God, in the name of God. To propose to halve the living Gospel, as the woman who had killed her child Kg1 3:26, and to think that the poor quivering remnants would be the living Gospel anymore! As though the will of God might, like those lower forms of His animal creation, be divided endlessly, and, keep what fragments we will, it would still be a living whole, a vessel of His Spirit! Such unrealities and inconsistencies would be a sore trial of faith, had not Jesus, who (cf. Joh 2:25), "knew what is in man," forewarned us that it should be so. The scandals against the Gospel, so contrary to all human opinion, are only all the more a testimony to the divine knowledge of the Redeemer.
What shall we do unto thee? - They knew him to be a prophet; they ask him the mind of his God. The lots had marked out Jonah as the cause of the storm; Jonah had himself admitted it, and that the storm was for "his" cause, and came from "his" God . "Great was he who fled, greater He who required him. They dare not give him up; they cannot conceal him. They blame the fault; they confess their fear; they ask "him" the remedy, who was the author of the sin. If it was faulty to receive thee, what can we do, that God should not be angered? It is thine to direct; ours, to obey."
The sea wrought and was tempestuous - , literally "was going and whirling." It was not only increasingly tempestuous, but, like a thing alive and obeying its Master's will, it was holding on its course, its wild waves tossing themselves, and marching on like battalions, marshalled, arrayed for the end for which they were sent, pursuing and demanding the runaway slave of God . "It was going, as it was bidden; it was going to avenge its Lord; it was going, pursuing the fugitive prophet. It was swelling every moment, and, as though the sailors were too tardy, was rising in yet greater surges, shewing that the vengeance of the Creator admitted not of delay."
Take me up, and cast me into the sea - Neither might Jonah have said this, nor might the sailors have obeyed it, without the command of God. Jonah might will alone to perish, who had alone offended; but, without the command of God, the Giver of life, neither Jonah nor the sailors might dispose of the life of Jonah. But God willed that Jonah should be cast into the sea - where he had gone for refuge - that (Wisdom 11:16) wherewithal he had "sinned, by the same also he might be punished" as a man; and, as a prophet, that he might, in his three days' burial, prefigure Him who, after His Resurrection, should convert, not Nineveh, but the world, the cry of whose wickedness went up to God.
For I know that for my sake - o "In that he says, "I know," he marks that he had a revelation; in that he says, "this great storm," he marks the need which lay on those who cast him into the sea."
The men rowed hard - , literally "dug." The word, like our "plowed the main," describes the great efforts which they made. Amid the violence of the storm, they had furled their sails. These were worse than useless. The wind was off shore, since by rowing alpine they hoped to get back to it. They put their oars well and firmly in the sea, and turned up the water, as men turn up earth by digging. But in vain! God willed it not. The sea went on its way, as before. In the description of the deluge, it is repeated Gen 7:17-18, "the waters increased and bare up the ark, and it was lifted up above the earth; the waters increased greatly upon the earth; and the ark went upon the face of the waters." The waters raged and swelled, drowned the whole world, yet only bore up the ark, as a steed bears its rider: man was still, the waters obeyed. In this tempest, on the contrary, man strove, but, instead of the peace of the ark, the burden is, the violence of the tempest; "the sea wrought and was tempestuous against them" . "The prophet had pronounced sentence against himself, but they would not lay hands upon him, striving hard to get back to land, and escape the risk of bloodshed, willing to lose life rather than cause its loss. O what a change was there. The people who had served God, said, Crucify Him, Crucify Him! These are bidden to put to death; the sea rageth; the tempest commandeth; and they are careless its to their own safety, while anxious about another's."
Wherefore (And) they cried unto the Lord - "They cried" no more "each man to his god," but to the one God, whom Jonah had made known to them; and to Him they cried with an earnest submissive, cry, repeating the words of beseeching, as men, do in great earnestness; "we beseech Thee, O Lord, let us not, we beseech Thee, perish for the life of this man" (i. e., as a penalty for taking it, as it is said, Sa2 14:7. "we will slay him for the life of his brother," and, Deu 19:21. "life for life.") They seem to have known what is said, Gen 9:5-6. "your blood of your lives will I require; at the hand of every beast will I require it and at the hand of man; at the hand of every man's brother will I require the life of man. Whoso sheddeth man's blood, by man shall his blood be shed, for in the image of God made He man" , "Do not these words of the sailors seem to us to be the confession of Pilate, who washed his hands, and said, 'I am clean from the blood of this Man?' The Gentiles would not that Christ should perish; they protest that His Blood is innocent."
And lay not upon us innocent blood - innocent as to them, although, as to this thing, guilty before God, and yet, as to God also, more innocent, they would think, than they. For, strange as this was, one disobedience, their whole life, they now knew, was disobedience to God; His life was but one act in a life of obedience. If God so punishes one sin of the holy Pe1 4:18, "where shall the ungodly and sinner appear?" Terrible to the awakened conscience are God's chastenings on some (as it seems) single offence of those whom He loves.
For Thou, Lord, (Who knowest the hearts of all men,) hast done, as it pleased Thee - Wonderful, concise, confession of faith in these new converts! Psalmists said it, Psa 135:6; Psa 115:3. "Whatsoever God willeth, that doeth He in heaven and in earth, in the sea and in all deep places." But these had but just known God, and they resolve the whole mystery of man's agency and God's Providence into the three simple words , as (Thou) "willedst" (Thou) "didst." "That we took him aboard, that the storm ariseth, that the winds rage, that the billows lift themselves, that the fugitive is betrayed by the lot, that he points out what is to be done, it is of Thy will, O Lord" . "The tempest itself speaketh, that 'Thou, Lord, hast done as Thou willedst.' Thy will is fulfilled by our hands." "Observe the counsel of God, that, of his own will, not by violence or by necessity, should he be cast into the sea. For the casting of Jonah into the sea signified the entrance of Christ into the bitterness of the Passion, which He took upon Himself of His own will, not of necessity. Isa 53:7. "He was offered up, and He willingly submitted Himself." And as those who sailed with Jonah were delivered, so the faithful in the Passion of Christ. Joh 18:8-9. "If ye seek Me, let these go their way, that the saying might be fulfilled which" Jesus spake, 'Of them which Thou gavest Me, I have lost none. '"
They took up Jonah - o "He does not say, 'laid hold on him', nor 'came upon him' but 'lifted' him; as it were, bearing him with respect and honor, they cast him into the sea, not resisting, but yielding himself to their will."
The sea ceased (literally "stood") from his raging - Ordinarily, the waves still swell, when the wind has ceased. The sea, when it had received Jonah, was hushed at once, to show that God alone raised and quelled it. It "stood" still, like a servant, when it had accomplished its mission. God, who at all times saith to it Job 38:11, "Hitherto shalt thou come and no further, and here shall thy proud waves be stayed," now unseen, as afterward in the flesh Mat 8:26, "rebuked the winds and the sea, and there was a great calm" . "If we consider the errors of the world before the Passion of Christ, and the conflicting blasts of diverse doctrines, and the vessel, and the whole race of man, i. e., the creature of the Lord, imperiled, and, after His Passion, the tranquility of faith and the peace of the world and the security of all things and the conversion to God, we shall see how, after Jonah was cast in, the sea stood from its raging" . "Jonah, in the sea, a fugitive, shipwrecked, dead, sayeth the tempest-tossed vessel; he sayeth the pagan, aforetime tossed to and fro by the error of the world into divers opinions. And Hosea, Amos, Isaiah, Joel, who prophesied at the same time, could not amend the people in Judaea; whence it appeared that the breakers could not be calmed, save by the death of (Him typified by) the fugitive."
And the men feared the Lord with a great fear - because, from the tranquility of the sea and the ceasing of the tempest, they saw that the prophet's words were true. This great miracle completed the conversion of the mariners. God had removed all human cause of fear; and yet, in the same words as before, he says, "they feared a great fear;" but he adds, "the Lord." It was the great fear, with which even the disciples of Jesus feared, when they saw the miracles which He did, which made even Peter say, Luk 5:8. "Depart from me, for I am a sinful man, O Lord." Events full of wonder had thronged upon them; things beyond nature, and contrary to nature; tidings which betokened His presence, Who had all things in His hands. They had seen "wind and storm fulfilling His word" Psa 148:8, and, forerunners of the fishermen of Galilee, knowing full well from their own experience that this was above nature, they felt a great awe of God. So He commanded His people, "Thou shalt fear the Lord thy God Deu 6:13, for thy good always" Deu 6:24.
And offered a sacrifice - Doubtless, as it was a large decked vessel and bound on a long voyage, they had live creatures on board, which they could offer in sacrifice. But this was not enough for their thankfulness; "they vowed vows." They promised that they would do thereafter what they could not do then ; "that they would never depart from Him whom they had begun to worship." This was true love, not to be content with aught which they could do, but to stretch forward in thought to an abiding and enlarged obedience, as God should enable them. And so they were doubtless enrolled among the people of God, firstfruits from among the pagan, won to God Who overrules all things, through the disobedience and repentance of His prophet. Perhaps, they were the first preachers among the pagan, and their account of their own wonderful deliverance prepared the way for Jonah's mission to Nineveh.
Now the Lord had (literally "And the Lord") prepared - Jonah (as appears from his thanksgiving) was not swallowed at once, but sank to the bottom of the sea, God preserving him in life there by miracle, as he did in the fish's belly. Then, when the seaweed was twined around his head, and he seemed to be already buried until the sea should give up her dead, "God prepared the fish to swallow Jonah" . "God could as easily have kept Jonah alive in the sea as in the fish's belly, but, in order to prefigure the burial of the Lord, He willed him to be within the fish whose belly was as a grave." Jonah, does not say what fish it was; and our Lord too used a name, signifying only one of the very largest fish. Yet it was no greater miracle to create a fish which should swallow Jonah, than to preserve him alive when swallowed . "The infant is buried, as it were, in the womb of its mother; it cannot breathe, and yet, thus too, it liveth and is preserved, wonderfully nurtured by the will of God." He who preserves the embryo in its living grave can maintain the life of man as easily without the outward air as with it.
The same Divine Will preserves in being the whole creation, or creates it. The same will of God keeps us in life by breathing this outward air, which preserved Jonah without it. How long will men think of God, as if He were man, of the Creator as if He were a creature, as though creation were but one intricate piece of machinery, which is to go on, ringing its regular changes until it shall be worn out, and God were shut up, as a sort of mainspring within it, who might be allowed to be a primal Force, to set it in motion, but must not be allowed to vary what He has once made? "We must admit of the agency of God," say these men when they would not in name be atheists, "once in the beginning of things, but must allow of His interference as sparingly as may be." Most wise arrangement of the creature, if it were indeed the god of its God! Most considerate provision for the non-interference of its Maker, if it could but secure that He would not interfere with it for ever! Acute physical philosophy, which, by its omnipotent word, would undo the acts of God! Heartless, senseless, sightless world, which exists in God, is upheld by God, whose every breath is an effluence of God's love, and which yet sees Him not, thanks Him not, thinks it a greater thing to hold its own frail existence from some imagined law, than to be the object of the tender personal care of the Infinite God who is Love! Poor hoodwinked souls, which would extinguish for themselves the Light of the world, in order that it may not eclipse the rushlight of their own theory!
And Jonah was in the belly of the fish - The time that Jonah was in the fish's belly was a hidden prophecy. Jonah does not explain nor point it. He tells the fact, as Scripture is accustomed to do so. Then he singles out one, the turning point in it. Doubtless in those three days and nights of darkness, Jonah (like him who after his conversion became Paul), meditated much, repented much, sorrowed much, for the love of God, that he had ever offended God, purposed future obedience, adored God with wondering awe for His judgment and mercy. It was a narrow home, in which Jonah, by miracle, was not consumed; by miracle, breathed; by miracle, retained his senses in that fetid place. Jonah doubtless, repented, marveled, adored, loved God. But, of all, God has singled out this one point, how, out of such a place, Jonah thanked God. As He delivered Paul and Silas from the prison, when they prayed with a loud voice to Him, so when Jonah, by inspiration of His Spirit, thanked Him, He delivered him.
To thank God, only in order to obtain fresh gifts from Him, would be but a refined, hypocritical form of selfishness. Such a formal act would not be thanks at all. We thank God, because we love Him, because He is so infinitely good, and so good to us, unworthy. Thanklessness shuts the door to His personal mercies to us, because it makes them the occasion of fresh sins of our's. Thankfulness sets God's essential goodness free (so to speak) to be good to us. He can do what He delights in doing, be good to us, without our making His Goodness a source of harm to us. Thanking Him through His grace, we become fit vessels for larger graces . "Blessed he who, at every gift of grace, returns to Him in whom is all fullness of graces; to whom when we show ourselves not ungrateful for gifts received, we make room in ourselves for grace, and become meet for receiving yet more." But Jonah's was that special character of thankfulness, which thanks God in the midst of calamities from which there was no human exit; and God set His seal on this sort of thankfulness, by annexing this deliverance, which has consecrated Jonah as an image of our Lord, to his wonderful act of thanksgiving. | <urn:uuid:ea49b7b5-b7ff-41f6-9341-88d6b5bddf22> | http://www.sacred-texts.com/bib/cmt/barnes/jon001.htm |

- A blockage that doesn't allow CSF to drain properly (more commonly)
- Brain tumors
- Cancer in the cerebrospinal fluid (CSF)
- Swelling in the CSF (such as sarcoidosis)
- Cysts in the brain
- Malformations of the brain, such as:
- Brain injuries
- Infections of the brain or the meninges can be caused by a number of agents including bacteria, mycobacteria, fungus, viruses, and parasites, such as:
- Problems with the blood vessel in the brain
- Bleeding into the brain or CSF space
- Headache (often worse when lying down or upon first awakening in the morning or with straining)
- Nausea / Vomiting
- Problems with balance
- Difficulty walking
- Poor coordination
- Personality changes
- Memory problems
- Dementia in the elderly
- Coma and death
- Slow development
- Loss of developmental milestones—no longer able to do activities they once could do
- Bulging fontanelle (soft spot on the head)
- Large head circumference
- Shunt placement (ventriculoperitoneal shunt)—a shunt (a tube placed into the brain) allows excess CSF to drain into another area, usually the abdomen. Sometimes a temporary extraventricular drain (EVD) is placed.
- Third ventriculostomy—a hole is created in an area of the brain. It allows the CSF to flow out of the area where it is building up.
- Removal of the obstruction of CSF flow. For example: removal of tumor or cyst
- Lumbar puncture (spinal tap)—This involves the insertion of a needle between the back bones in the back to remove excess CSF.
- Medicines—In some cases, medicines, such as acetazolamide (Diamox) and furosemide (Lasix), may decrease the production of CSF.
- Other medicines such as steroids or mannitol may decrease swelling around lesions that are causing obstruction of CSF flow.
- Get regular prenatal care.
- Keep your child’s vaccines up to date.
- Protect yourself or your child from head injuries.
Toxoplasmosis—foodborne illness that may be prevented by:
- Carefully cook meat and vegetables.
- Correctly clean contaminated knives and cutting surfaces.
- Avoid handling cat litter, or wear gloves when cleaning the litter box.
- Cytomegalovirus (CMV)—talk to your doctor about identifying CMV in pregnancy
- Lymphocytic choriomeningitis virus (LCV) from pet rodents (mice, rats, hamsters)—avoid rodent contact during pregnancy
- Viruses that cause chickenpox or mumps—can be prevented with vaccinations

Malheur Cave, 13 miles east of Princeton, is 3,000 feet long, and the height varies from 8 feet near the entrance to a maximum of 20 feet far back in the cave. An underground lake fills the lower end of the cave, and fluctuation can cause the water to raise within 1,000 feet of the entrance.
The Masons, Robert Burns Masonic Lodge No. 97, used this cave extensively for ceremonies and other functions. The curious come on a year-round basic, the kids for fun, the scientists for answers to long-time questions, and the cavers, just to meet or visit an old friend. The Masons own the cave, but have left it open to whoever wishes to cool off on a hot summer day, explore its many wonders and paddle its waters, just as it was done decades ago
After passing under the low, arching entrance, the passage opens to a wide expanse of level dirt floor. The walking passage eventually reaches two rows of wooden beachers used by the Masons. After passing the cement platform, the passage begins to get more muddy and filled with boulders of breakdown from the ceiling. The point where the passage turns to water depends on the time of year and the level of the adjacent reservoir. Beneath the waters is a submerged boat and soon the waters reach to the ceiling of the passage. Divers have plumbed to the end of the cave. | <urn:uuid:6f9e56f9-f71d-41b2-b86b-d1f5426e82a6> | http://oregoncaves4u.com/Malheur%20Cave.html |

On September 19, the Cary Institute hosted a one-day conference on the impacts of tropical storms Irene and Lee on the Hudson River. Organized by the Hudson River Environmental Society, with leadership from Cary's Stuart Findlay, the forum examined how the river and estuary responded to the storms, which dropped an estimated 12-18 inches of rainfall throughout the Hudson Valley and Catskill regions. Topics included dredging, sediment transport, water quality, impacts to fish, and future management practices.
In late October, Gary Lovett will present his assessment of the health of the Catskill Forest at the second Catskill Environmental Research & Monitoring Conference (CERM). The forum brings together research on the region, to better understand the effects of extreme weather, air pollution, invasive species, biodiversity loss, and habitat fragmentation. The Catskills provide the majority of New York City's drinking water supply; CERM forums help coordinate research and identify research agendas to protect these resources.
In November, Cary Institute will hold a two-day conference examining the effects of climate change on plant, animal, and microbial species. The invitation-only event is being organized by Richard Ostfeld, Shannon LaDeau, and Amy Angert (University of British Columbia). With more than 50 invited experts, the conference's goal is to identify tools that will help lessen the negative effects of climate change on biodiversity, disease risk, extinction, and ecosystem function. | <urn:uuid:40f6fcd0-48f9-4b94-a078-36492fab999c> | http://www.caryinstitute.org/newsroom/conferences?page=0%2525252C3%25252C2%252C2 |
In our Torah portion this week, it is written that Jacob "came to a certain place and stayed there that night" (Gen. 28:11). The Hebrew text, however, indicates that Jacob did not just happen upon a random place, but rather that "he came to the place" -- vayifga bamakom (וַיִּפְגַּע בַּמָּקוֹם). The sages therefore wondered why the Torah states bamakom, "the place," rather than b'makom, "a place"? Moreover, the verb translated "he came" is yifga (from paga': פָּגַע), which means to encounter or to meet, suggesting that Jacob's stop was a divine appointment.
The Hebrew word makom ("place") comes from the verb kum (קוּם), meaning "to arise," and in Jewish tradition, ha-makom became a Name for God. The early sages therefore interpreted the verse to mean that Jacob actually had his dream while in Jerusalem rather than in Bethel... Indeed, the Talmud identifies "the place" Jacob encountered as Mount Moriah - the location of the Akedah - based on the language used in Genesis 22:4: "On the third day, Abraham raised his eyes and saw the place (הַמָּקוֹם) in the distance" (Sanhedrin 95b, Chulin 91b). If that is the case (i.e., if Jacob had been miraculously transported south from the mountains of Bet El to what would later be called Jerusalem), then Jacob's dream of the ladder would have functioned as a revelation of the coming glory of the resurrected Messiah - the Promised Seed whom Isaac foreshadowed and through whom all the families of the earth would be blessed. It was Yeshua, the Angel of the LORD, who came to "descend" (as the Son of Man) and to "rise" (as the resurrected LORD) to be our mediator before God (see John 1:47-51). Perhaps the Talmud makes the claim that Jacob's vision occurred in Jerusalem because Bethel later became the site for one of two idolatrous shrines (i.e., the golden calves at Bethel and Dan) established by King Jeroboam of the Northern Kingdom which he set up to discourage worship at Solomon's Temple in the City of Jerusalem (see 1 Kings 12:28-29).
At any rate, the Hebrew word for "intercessor" (i.e., mafgia: מַפְגִּיעַ) comes from the same verb (paga') mentioned in our verse. Yeshua is our Intercessor who makes "contact" with God on our behalf. Through His sacrifice for our redemption upon the cross (i.e., his greater Akedah), Yeshua created a meeting place (paga') between God and man. Therefore we see the later use of paga' in Isaiah 53:6, "...the Lord laid on him (i.e., hifgia bo: הִפְגִּיעַ בּוֹ) the iniquity of us all," indicating that our sins "fell" on Yeshua as He made intercession for us (i.e., yafgia: יַפְגִּיעַ) for us (Isa. 53:12). Because of Yeshua, God touches us and we are able to touch God... And today, our resurrected LORD "ever lives to make intercession (paga') for us" (Heb. 7:25). He is still touched by our need and sinful condition (Heb. 4:15).
כֻּלָּנוּ כַּצּאן תָּעִינוּ אִישׁ לְדַרְכּוֹ פָּנִינוּ
וַיהוָה הִפְגִּיעַ בּוֹ אֵת עֲוֹן כֻּלָּנוּ
kul·la·nu katz·on ta·i·nu, ish le·dar·ko pa·ni·nu
vadonai hif·gi·a bo, et a·von kul·la·nu
"All we like sheep have gone astray; we have turned each to his own way;
but the LORD has laid on him the iniquity of us all."
Paga' is also a term for warfare or violent meetings, and this alludes to the collision between the powers of hell and the powers of heaven in the outworking of God's plan of redemption: "... he (i.e., the Savior/Messiah) will crush your head (ראשׁ), and you (i.e., the serpent/Satan) will crush his heel (עָקֵב)." This was the original prophecy of redemption, an encounter with evil that would provide atonement and retribution (see the "Gospel in the Garden"). Rabbi Yechezkel Levenstein, the mashgiach of Ponevezh, points out that the entire future of the Jewish people hinged on the vision given to Jacob - and in Jacob's response to it. Had he been prevented to return (i.e., through Laban's schemes to keep him in Charan), the Jewish people would have become enslaved and assimilated into the people of Aram, and ultimately the Messiah Himself would not have been born. Laban, then, embodied the desire of Satan to thwart the coming of the Promised Seed, and therefore he may be compared to Pharaoh, who likewise tried to enslave Israel in Egypt...
As I mentioned in my additional commentary on parashat Balak, Laban's worship of the serpent (nachash) led him to become one of the first enemies of the Jewish people (see "The Curses of Laban"). He tried to make Jacob a slave from the beginning, later claiming that all his descendants and possessions belonged to him (Gen. 31:43). After Jacob escaped from his clutches, Laban had a son named Beor (בְּעוֹר) who became the father of the wicked prophet Balaam (בִּלְעָם). In other words, the "cursing prophet" Balaam was none other than the grandson of diabolical Laban. Here is a diagram to help you see the relationships:
In Jewish tradition, Laban (the patriarch of Balaam) is regarded as even more wicked than the Pharaoh who enslaved the Jews in Egypt. This enmity is enshrined during the Passover Seder when we recall Laban's treachery as the one who "sought to destroy our father, Jacob." Spiritually understood, Laban's hatred of Jacob (i.e., Israel) was intended to eradicate the Jewish nation at the very beginning. Had Laban succeeded, Israel would have been assimilated and disappeared from history, and more radically, God's plan for the redemption of humanity through the Promised Seed would have been overturned....
Thankfully, Jacob was enabled by God's grace to overcome Laban and to return to the Promised Land, and even more thankfully, the Messiah was able to crush the rule of Satan through His atoning sacrifice and resurrection at Moriah. Yeshua, our ascended LORD, is ha-makom - the place where we encounter the Living God....
The authority and reign of Satan has been gloriously vanquished by Yeshua our Savior, blessed be He, though there is coming a time of judgment for all who dwell upon the earth. The time immediately preceding the appearance of the Messiah will be a time of testing in which the world will undergo various forms of tribulation, called chevlei Mashiach (חֶבְלֵי הַמָּשִׁיחַ) - the "birth pangs of the Messiah" (Sanhedrin 98a; Ketubot, Bereshit Rabbah 42:4, Matt. 24:8). Some say the birth pangs are to last for 70 years, with the last 7 years being the most intense period of tribulation -- called the "Time of Jacob's Trouble" / עֵת־צָרָה הִיא לְיַעֲקב (Jer. 30:7). The climax of the "Great Tribulation" (צָרָה גְדוֹלָה) is called the great "Day of the LORD" (יוֹם־יהוה הַגָּדוֹל) which represents God's wrath poured out upon a rebellious world system. On this fateful day, the LORD will terribly shake the entire earth (Isa. 2:19) and worldwide catastrophes will occur. "For the great day of their wrath has come, and who can stand?" (Rev. 6:17). The prophet Malachi likewise says: "'Surely the day is coming; it will burn like a furnace. All the arrogant and every evildoer will be stubble, and that day that is coming will set them on fire,' says the LORD Almighty. 'Not a root or a branch will be left to them'" (Mal. 4:1). Only after the nations of the world have been judged will the Messianic kingdom (מַלְכוּת הָאֱלהִים) be established upon the earth. Yeshua will return to Jerusalem to establish His glorious kingdom (as foretold by the prophets) and then "all Israel will be saved." The Jewish people will finally understand that Mashiach ben Yosef (the Suffering Servant) and Mashiach ben David (the anointed King of Israel) are one and the same... The 1,000 year reign of King Messiah will then commence (Rev. 20:4).
Presently our responsibility is to come to "the place" (ha-makom) where God's work of redemption was completed - that is, to the Cross of Yeshua. There we turn to God in repentance (teshuvah) and consign our sins to the judgment borne for us through Yeshua's sacrifice as our kapporah (atonement). By faith we understand that the resurrected Savior is forever ha-makom, "the place" where God meets with us, and we learn to abide in His gracious Presence by means of the Holy Spirit. We cease striving to justify ourselves (i.e., by virtue of works), but instead receive God's love and Spirit into our hearts. This means that we will study the Scriptures (truth), obey the Torah of Yeshua and His emissaries, and share the good message of God's redemption with a lost and dying world...
We are fast approaching, however, the prophesied "End of Days" (acharit hayamim), when the LORD will return to earth to "settle accounts" with its inhabitants (including those who profess to obey Him). We do not have much more time, chaverim. We must encourage people to call upon the LORD for salvation before it is too late...

The Appalachian Mountain range is nearly 1,500 miles long stretching from the southeast corner of Canada to Alabama. The Cumberland Gap, a natural break in the range near the eastern borders of Kentucky and Tennessee, is now a paved highway known as US 25E. A section of US 25E that now passes through a tunnel underneath the mountain is called the Cumberland Gap Tunnel.
Cars and trucks have replaced Conestoga wagons, but the route, now a paved highway, still offered challenges to travelers. The steep grade and sharp turns of US 25E were the cause of many traffic accidents. So many, in fact, that the 2.3-mile stretch of highway earned the unfortunate nickname, “Massacre Mountain.”
To make the route safer, a section of US 25E was relocated under the mountain by constructing a tunnel. This also helped restore the appearance of the mountain to the way it looked in the late 1700s, in the days of Daniel Boone.
The Cumberland Gap Tunnel passes through a large limestone formation within the Cumberland Mountain. Limestone, made of the mineral calcite, is slightly soluble in water. When rainwater seeps through cracks and between layers of limestone, it dissolves some of the calcite it contacts. Bit by bit, the flowing water removes calcite and the cracks grow larger, eventually forming caves. The resulting cave system is a natural conduit for underground water flow.
Where the tunnel passed through a cavern, concrete was poured to form an artificial ceiling structure. This, of course, blocked the water flow. The cavern, which runs almost perpendicular to the tunnel, was kept in a nearly natural state by allowing the water flow to continue its normal course through a conduit five feet in diameter built under the roadway. There is also a passageway constructed above the tunnel to allow for air and water movement. Thus, the cave system continues to function as a natural drainage system.
Engineers designed an additional drainage system to collect percolating groundwater that hits the impervious tunnel walls. This system includes a manmade streambed parallel to the tunnel, running beneath the roadbed from end to end.
The streambed is made of limestone gravel, and water flows between and around these gravel particles. When groundwater percolates through limestone rock layers before reaching the gravel bed, that drainage water is already saturated with calcium carbonate (the chemical name for calcite) and does not dissolve calcite from the gravel. Without loss from dissolving, loss of gravel caused by abrasion and erosion occurs at a slow and predictable rate.
However, most of Cumberland Mountain is made of rock other than limestone, such as sandstone, shale, and siltstone. This means that much of the water entering the tunnel’s drainage system is not already saturated with calcium carbonate and does dissolve gravel material. Similar to the way the cave system developed long ago in the limestone formation within Cumberland Mountain, the artificial streambed is gradually washing away. During the first ten years of the tunnel’s existence, enough gravel matter was removed to cause the roadway above to sag and need repair. As of 2009, a long-term solution had not yet been determined.
To learn about the construction of a different kind of tunnel, one that went underwater, check out Building the Channel Tunnel.

Wondering what to do with that dead cow in your backyard or those dead batteries in your flashlight?
The Center for the Development of Recycling—a partnership between San Jose State University’s Environmental Studies Department and Santa Clara County—has an online tool to guide you on how and where to recycle anything from the dead cow and batteries to painted or stained wood waste and everything in between.
Nov. 15 is America Recycles Day so take part in it and use the tool if you find one of the few materials the City of Milpitas does not accept. The tool is easy to use: Scroll the list of materials to find the one you wish to recycle, click on it and it will move to a box on the right. When you have your list complete fill in your ZIP code and click on the “find results” button.
It will return a list of companies that accept the specific material, the company's location and/or phone number, website links, whether the material can be picked up or dropped off, and other useful information.
Batteries, for example, are accepted at several places in and around Milpitas. That dead cow is a little trickier. Four places accept dead cows and two of them have restrictions on the cow’s age.
Recycling is something that can be embraced as a lifetime commitment. Think the three Rs—reduce, reuse and recycle.
One way to reduce is to stop junk mail from being delivered to your home. The Bay Area Outreach Coalition offers a stop junk mail kit (see the attached PDF for more detail or visit www.stopjunkmail.org) to get rid of those annoying catalogs, ads, promotional materials and other unwanted mail that winds up in your recycle bin.
America Recycle Day includes events such as the one at GreenMouse Recycling in San Jose that is hosting a three-day recycle-athon between Nov. 15 and 17 with a goal of recycling 25,000 pounds of electronic waste. Recycle something with a screen, such as a laptop, monitor, television or cell phone, and recieve a Starbucks gift card. Then take that Starbucks gift card and a friend to the nearest store and take advantage of the 2-for-1 offer going on. It's a win-win! | <urn:uuid:0845aa46-36c9-44b3-ab63-507957fc7c7f> | http://milpitas.patch.com/groups/editors-picks/p/nov-15-is-america-recycles-day-so-reduce-reuse-and-re200794663e |

Rainy Side Notes
Allium karataviense is a spunky plant with a large flower globe. It is a dwarf ornamental onion compared to the giant species in the Melanocrommyum group of alliums, in which it belongs. It grows exceptionally well in our Mediterranean climate, as the plants go dormant by the time our annual drought comes around. Some gardeners grow the species and its cultivars because it has the most attractive foliage in the entire genus. Its horizontal, long, leathery, pleated foliage is green with a striking purple cast. As the blossom first opens, it is nestled on top of the attractive foliage; the flowering stems continue to grow. It pushes the large, spherical umbels up and away from the leaves as they begin to look shabby. When you plant bulbs en masse in a garden bed or container, use companion perennials that are late in filling out, or annuals to fill in any bare soil the bulb's dormant state leaves behind.
Sensitive to excess moisture, these alliums are prone to rot, so grow them in well-drained soil in the ground or in deep containers with excellent drainage. Some A. karataviense cultivars available are 'Ivory Queen', 'Lucky' and 'Red Globe'.

Imprint training pioneer Dr. Robert Miller debunks some of the common misconceptions about this useful foal handling technique.
The technique of imprinting has been used to help train foals for more than 50 years, but common misconceptions about what it means to imprint young horses still exist. While recent years have seen more and more owners and trainers fully commit to properly using this valuable foal handling procedure, a few basic misunderstandings still remain that prevent those who attempt to apply imprint training techniques from achieving the results that they desire.

Dr. Robert Miller, one of the pioneering practitioners of equine imprint training, believes that proper implementation of imprint training principles make a horse more trainable and easier to handle, but only if it is done correctly and completely—and only if the person performing the technique is realistic about exactly what the process is meant to achieve.
“You’re not going to change [a foal’s] personality,” Miller says. “Energetic will be energetic. Lazy will be lazy. Highly reactive will be highly reactive. Indifferent will be indifferent. Intelligent will be intelligent. But what [imprinting] does is, if you do it right after they are born, before any other learning goes in—you build a foundation.”
Understanding what that foundation is meant to support is the key to getting the long-term results that proper imprint training can provide.
“You’re not imprint training the body,” Miller says. “You’re imprint training the mind.”
In the wild, horse have always been prey animals and, therefore, a foal must be able to get to its feet within an hour after birth and run with its herd as a means of self defense. This history means that even domesticated horses are born with a healthy paranoia of just about everything. Fear is the natural first response a horse feels to new stimuli. They have to learn not to fear people, objects and even other animals.
It is almost impossible to teach a horse anything if his focus is on self preservation.
“It applies to us, too,” Miller says. “If we are preparing to take a test, and we’re really scared, our learning ability isn’t nearly as great as if we are laid back and relaxed and can think things out.”
Fear and anxiety interfere with the learning procedure because, in any animal, it increases the primary defensive behavior.
“In some species, [the defensive behavior] is to fight, so fear will precipitate an attack,” Miller explains. “But in the horse, fear usually precipitates flight or the desire for flight.
“In the horse—and this is only true in the horse and not dogs, cattle or people—control of the feet controls the mind. When you control the animal’s primary defense, you control the mind. In wolves, it’s control of the muzzle. In the human being, it’s control of the hands. In horses, it’s control of the feet. Every school of horsemanship has relied upon [this concept] even if they didn’t understand why it worked.”
The main goal of all imprint training is to minimize the fear responses that can keep a horse from learning.
“If we don’t have the fear, the horse isn’t thinking about running away,” Miller says. “Instead, the horse is paying attention and subject to quick learning.”
It is important to Miller that people understand that imprinting and training are two different things—a fact that he believes sometimes gets overlooked.
“Imprinting is a visual memorization of what the foal sees moving around it, and it triggers an instinct to trust and to follow,” Miller says. “Training is learning by reinforcement. The only reason I called the process Imprint Training is because it’s training during the imprint period.”
In nature, a foal imprints on its mother and the other members of its herd, serving to protect the foal against predators in the wild. However, foals can also imprint on a variety of other creatures, too.
“In domestication, it can be a human, or a dog or a piece of machinery,” Miller says. “Anything that moves, the foal will be imprinted upon it and tend to want to go to it and be near it and trust it.”
It is this inherent trust that Miller uses to teach the newborn foal that the world isn’t nearly as scary as it would otherwise believe it to be.
“In an hour to hour and a half, I can get so much done with a foal,” he says. “It’s a great time saver.”
Doing It Right
Miller often regrets calling the process Imprint Training because people confuse the meaning of term.
“I often have people come up to me and say, ‘I imprinted my horse when he was 6 months of age,’ or it was an 18 month old,” he says. “They don’t understand that imprinting only occurs in the horse [immediately after birth].
“It’s not that way with all species. Dogs, for example, imprint between 6 and 7 weeks of age. But that is a different species. They are not precocial. They are helpless as babies, just like humans. Whereas in the precocial species like horses, the ones who must be able to run from danger by the time they are one hour of age, the imprinting begins in the hour after birth.”
To Miller, the advantages of imprint training are that it happens very quickly, you don’t have to rely on or undo any previous negative learning, and since the foal is already down and has yet to stand, you can prepare a foal for most of what it needs to know for the rest of its life in about an hour.
During that time, Miller touches literally every part of the foal—from nose to tail and from ears to hooves—with the goal of habituating [making it comfortable with and unafraid of] common loud or frightening sounds or movements that can spook a horse, being touched in the areas that will be handled during farriery and during veterinary examinations of every body opening, as well as pressure in the saddle area. Teaching foals not to fear pressure in the girth area is usually saved for the second session when they are already on their feet.
“You remove the anxiety, the fear,” Miller says, “and they are quicker to learn other things.”
The mistake most people make when imprint training is that they don’t do enough at the right times, either during the first session when the foal has yet to stand, or during subsequent training sessions when the foal is on its feet.
“I poll every audience that I speak to,” Miller says, “and what I’ve learned from doing this over the last four decades is the two most common mistakes are rushing the training and failing to follow up after the first session.”
Miller says it is almost always men who make the mistake of rushing the first session of imprint training.
“They are usually working for a ranch or farm,” he says, “and they show them my video and tell them they want them to do this with their foals, and they rush it.”
For example, when Miller is habituating a foal to having his feet touched, he taps the bottom of each hoof with his hand 100 times to ensure that he’s tapping long enough for the foal’s initial fear response to the touch to wear off and he learns that having his foot touched isn’t something to be afraid of.
“Men will often tap the hoof 5-10 times and quit,” Miller says, “and what they’ve taught the foal to do is to fear that touch. They have failed to habituate by stopping during the fear and flight period in the foal’s mind.”
By doing this, they have actually sensitized the foal to fear of having its feet touched, and the next day, the person can’t get anywhere near them to continue the second phase of the training.
“Whereas the foals I do, you can touch them anywhere on their body the next day,” Miller says. “Women just love this part of the training because of the intimacy of it.”
Conversely, Miller states it is almost always women who fail to complete imprint training after the first session.
“They do the birth session, but they don’t do sessions two through seven when the foal is on its feet, which is where you get their respect,” he says of the sessions where the foal is habituated to a variety of body pressure and movement cues, as well as leading and tying.
“I ask them ‘Why didn’t you do it?’ and the answer is always the same. ‘He didn’t like it, so I didn’t do it.’ They often admit that they got bad results, but claim to know what they did wrong.”
The Lessons Transfer
While one of the major complaints about imprint training is that the foal will only respond to the person he imprinted upon, Miller doesn’t believe this to be the case. The foal may be slightly more responsive to that individual, but if that person imprint trains the foal properly, anyone who handles that horse in the future will have an easier time than if the horse had never received imprint training.
Miller admits that the trust an imprinted animal gains in its imprinter doesn’t transfer directly to all other humans. However, it does prepare them for what other people may do with them and makes the horse’s transition to the new handler’s style easier and faster.
“Say you have an individual sacking out a colt who has never been ridden with a blanket, and he stands perfectly happy while everything happens,” Miller says. “If a stranger comes along with a blanket, he’s going to react with fear to the stranger, but once he’s past that and the blanket begins, the attitude is, ‘Oh, I remember,’ and the horse relaxes.
“As far as their future talent on the racetrack, as a jumping horse, as a roping horse or a barrel horse, imprint training doesn’t interfere. It actually enhances it because you remove most of the fear factors [that can interfere with learning]. If a foal has learned to be unafraid of a human presence and being touched on any part of its body, and now you want to make a rope horse out of it, it’s not going to get all boogered when the rope drags on the ground beside it or you throw it out in front of him. I wouldn’t say it improves performance, but it enhances learning.”
The same basic principle applies to imprint training a young horse to be relaxed in a stall area around other horses, in your training pen and especially when approaching what some horses consider to be a scary object—a barrel. Once a horse is hauled to a show, the environment may be different and cause anxiety temporarily, but the similarity of the situation to what they’ve experienced before will help the horse relax and perform to the best of its ability faster.
Although imprint training doesn’t affect a horse’s personality, it will help more reactive horses become more handlable. A highly reactive individual will still remain flighty, but if you’ve de-sensitized him to the everyday things he might spook at—which interferes with what you’re trying to teach them at any point—it helps him learn what you’re teaching faster.
Respect, Not Fear
Imprint training has gained wide acceptance over the last 25 years, but there are still some trainers who object to the technique. Many object for a one primary reason—they believe that since imprinting lessens a horse’s fears, it makes the horse much harder for anyone who didn’t imprint that horse to control.
“The objective in training horses should be 100 percent respect and zero percent fear,” Miller states. “Some people think you’ve got to show them who’s boss. You’ve got to show a horse who’s the leader, but you don’t have to show them who’s boss, which infers fear of the boss. It’s not necessary to be able to control the horse.”
The idea that fear of humans is necessary to maintain control of a horse and to get it to do what you want it to do ignores a fact that practitioners of natural horsemanship have known for decades—if you really want your horse to want to work for you, fear can’t be part of the equation.
For Miller, the goal of imprint training is to get the horse to see the human as a herd leader and be submissive to his or her requests as a result. You don’t want a horse to fear you, but depend on you for leadership and guidance. When done correctly, imprint training enhances a horse’s relationship with all humans. All it takes is putting in the effort to achieve the results you want instead of looking for a quick, fear-based fix.
According to Miller, in wild mustang herds, the leader is most often the oldest mare, which indicates that physical strength has nothing to do with gaining the respect of the horse or achieving leadership. The stallion, who many would perceive as the natural choice to be the leader, runs in back and chases the stragglers to get them to keep up with the leading mare, serving as more of a guardian for the herd than a leader of it.
“There are still some trainers that object to [imprint training], and there are still trainers who do it improperly and criticize the technique,” Miller says. “Any training technique ever devised, if you don’t do them correctly, you can’t expect good results.
“I hear people say, ‘I did my colt Parelli style,’ or, ‘I did my colt Kurt Pate style, and it didn’t do any good.’ Well, they didn’t do it correctly because they are very good training techniques. They blame the technique rather than themselves.”
But as with any training program, in the end, you and your horse will get out of it what you put into it. After 50 years of teaching and practicing the techniques of imprint training, Miller believes that if it is done properly, it will absolutely make a difference in the teachability and overall confidence and happiness of the horse.
“Simply put, imprint training works,” Miller says emphatically. “It works consistently and very, very effectively.
“The foal respects the mare, but is also bonded to her and trusts her. We can get exactly the same thing, trust combined with respect.”
Dr. Robert Miller graduated from Colorado State University and settled in Thousand Oaks, Calif., where he founded the Conejo Valley Veterinary Clinic. He retired in 1987 after 31 years as a renowned veterinarian and expert in ethology (the study of animal behavior) in order to devote his full time to the teaching of equine behavior and to support the revolution in horsemanship that began in the Western United States in the late 20th Century and is now a worldwide phenomenon.
He is best known for his scientifically based system of training newborn foals, called imprint training, which is now in use all over the world. He has authored several books, including Imprint Training of the Newborn Foal, and has been on the editorial staff of several veterinary practice and horse industry magazines. | <urn:uuid:4901912d-84db-446b-92c3-2710683c63b8> | http://www.barrelhorsenews.com/articles/how-to/3885 |
This article published by Yongyut Trisurat, Anak Pattanavibool, George A. Gale and David H. Reed in CSIRO Publishing. Wildlife Research. 2010, 37, 401-412, demonstrates how the CAP principles helped assess wildlife population viability for multiple species in the Western Forest Complex in Thailand. If you wish to request a copy of the article, please contact Yongyut Trisurat (email@example.com).
Context. Assessing the viability of animal populations in the wild is difficult or impossible, primarily because of limited data. However, there is an urgent need to develop methods for estimating population sizes and improving the viability of target species.
Aims. To define suitable habitat for sambar (Cervus unicolor), banteng (Bos javanicus), gaur (Bos gaurus), Asian elephant (Elephas maximus) and tiger (Panthera tigris) in the Western Forest Complex, Thailand, and to assess their current status as well as estimate how the landscape needs to be managed to maintain viable populations.
Methods. The present paper demonstrates a method for combining a rapid ecological assessment, landscape indices, GIS-based wildlife-habitat models, and knowledge of minimum viable population sizes to guide landscape-management decisions and improve conservation outcomes through habitat restoration.
Key results. The current viabilities for gaur and elephant are fair, whereas they are poor for tiger and banteng. However, landscape quality outside the current distributions was relatively intact for all species, ranging from moderate to high levels of connectivity. In addition, the population viability for sambar is very good under the current and desired conditions.
Conclusions. If managers in this complex wish to upgrade the viabilities of gaur, elephant, tiger and banteng within the next 10 years, park rangers and stakeholders should aim to increase the amount of usable habitat by ~2170 km2 or 17% of existing suitable habitats. The key strategies are to reduce human pressures, enhance ungulate habitats and increase connectivity of suitable habitats outside the current distributions.
Implications. The present paper provides a particularly useful method for managers and forest-policy planners for assessing and managing habitat suitability for target wildlife and their population viability in protected-area networks where knowledge of the demographic attributes (e.g. birth and death rates) of wildlife populations are too limited to perform population viability analysis. | <urn:uuid:88f965df-95a7-4e97-bcdf-27d8ec0cad74> | http://www.conservationgateway.org/ExternalLinks/Pages/improving-viability-large.aspx |

As far as scary-looking fish go, the adult sea lamprey is right up there with the sharks. It’s about 3 feet long, with concentric rings of teeth inside a jawless, suction-cup mouth. After trapping its prey by sucking, the lamprey scrapes off the skin using a tooth at the end of its tongue, and then sucks out the blood. Since the lamprey has good taste in fish – preferring trout, salmon, bass –it’s the target of a federal lampricide program in the Great Lakes region, where it has nearly devoured some of these stocks.
But no creature is all bad. “The lamprey has a really beautiful spinal cord,” says Ona Bloom, an MBL Research Fellow from The Feinstein Institute for Medical Research. Together with Jennifer Morgan (Univ. of Texas at Austin) and David Parker (Univ. of Cambridge), who are recipients of an MBL sponsored Albert and Ellen Grass Faculty Research Grant, Bloom and her colleagues are studying the lamprey’s remarkable ability to recover from severe spinal cord injury. “We have been talking for years about collaborating on these studies,” says Bloom. “ The MBL gives us a wonderful opportunity to do that.”
One of the most primitive of living vertebrates, the sea lamprey is a good animal in which to analyze the acute response to spinal cord injury, which is Bloom’s focus, and how the nervous system functions are restored, which interests Morgan and Parker. “We want to understand the differences between the robust recovery in lampreys and how that contrasts with what happens in humans with spinal cord injury,” says Morgan. “If we can understand processes in the lamprey that contribute to recovery, then we can see if those processes can promote better recovery in higher vertebrates.” | <urn:uuid:d2859141-f376-49a0-b7e8-6ba4308c1c84> | http://blog.mbl.edu/?p=471 |

Here we present a chronological tour of dialysis from the beginning.

The first practical artificial kidney was developed during World War II by the Dutch physician Willem Kolff. The Kolff kidney used a 20-meter long tube of cellophane sausage casing as a dialyzing membrane. The tube was wrapped around a slatted wooden drum. Powered by an electric motor, the drum revolved in a tank filled with dialyzing solution. The patient’s blood was drawn through the cellophane tubing by gravity as the drum revolved. Toxic molecules in the blood diffused through the tubing into the dialyzing solution. Complete dialysis took about six hours. The Kolff kidney effectively removed toxins from the blood, but because it operated at low pressure, it was unable to remove excess fluid from the patient’s blood. Modern dialysis machines are designed to filter out excess fluid while cleansing the blood of wastes.
Blood was drained from the patient into a sterile container. Anticlotting drugs were added, and the filled container was hung on a post above the artificial kidney and connected to the cellulose acetate tubing that was wound around the wooden drum. A motor turned the drum, pulling the blood through the tubing by gravity.
The tank underneath the drum was filled with dialyzing fluid. As the blood-filled tubing passed through this fluid, waste products from the blood diffused through the tubing into the dialyzing fluid. The cleansed blood collected in a second sterile container at the other end of the machine. When all of the blood had passed through the machine, this second container was raised to drain the blood back into the patient.
George Thorn, MD, of the Peter Bent Hospital in Boston, MA, invited Willem Kolff, MD, to meet with Carl Walters, MD, and John Merrill, MD, to redesign and modify the original Kolff Rotating Drum Kidney. The artificial kidney was to be used to support the first proposed transplant program in the United States. This device was built by Edward Olson, an engineer, who would produce over forty of these devices, which were shipped all over the world.
Cellulose acetate tubular membrane, the same type of membrane that is used as sausage casing, was wrapped around the drum and connected to latex tubing that would be attached to the patient’s bloodstream. The drum would be rotating in the dialyzing fluid bath that is located under the drum.
The patient’s blood was propelled through the device by the “Archimedes screw principle” and a pulsatile pump. A split coupling was developed to connect the tubing to the membrane, a component necessary to prevent the tubing and membrane from twisting. This connection is at the inlet and outlet of the rotating drum.
The membrane surface area could be adjusted by increasing or decreasing the number of wraps of tubing. The Plexiglas™ hood was designed to control the temperature of the blood. The cost of this device was $5,600 in 1950.
Murphy WP Jr., Swan RC Jr., Walter CW, Weller JM, Merrill JP. Use of an artificial kidney. III. Current procedures in clinical hemodialysis. J Lab Clin Med. 1952 Sep; 40(3): 436-44.
Leonard Skeggs, PhD, and Jack Leonards, MD, developed the first parallel flow artificial kidney at Case Western Reserve in Cleveland, OH. The artificial kidney was designed to have a low resistance to blood flow and to have an adjustable surface area.
Two sheets of membrane are sandwiched between two rubber pads in order to reduce the blood volume and to ensure uniform distribution of blood across the membrane to maximize efficiency. Multiple layers were utilized. The device required a great deal of time to construct and it often leaked. This was corrected by the use of bone wax to stop the leak.
The device had a very low resistance to blood flow and it could be used without a blood pump. If more than one of these units were used at a time, a blood pump was required. Skeggs was able to remove water from the blood in the artificial kidney by creating a siphon on the effluent of the dialyzing fluid. This appears to be the first reference to negative pressure dialysis.
This technology was later adapted by Leonard Skeggs to do blood chemistries. It was called the SMA 12-60 Autoanalyzer.
This artificial kidney was developed to reduce the amount of blood outside of the body and to eliminate the need for pumping the blood through the device.
Guarino used cellulose acetate tubing. The dialyzing fluid was directed inside the tubing and the blood, entering the device from the top, cascading down the membrane. The metal tubing inside the membrane gave support to the membrane.
The artificial kidney ahd a very low blood volume, but it had limited use because there was concern regarding the possibility of the dialyzing fluid leaking into the blood.
Von Garrelts had constructed a dialyzer in 1948 by wrapping a cellulose acetate membrane around a core. The layers of membrane were separated by rods. It was very bulky and weighed over 100 pounds.
William Inouye, MD, took this concept and miniaturized it by wrapping the cellulose acetate tubing around a beaker and separating the layers with fiberglass screening. He placed this “coil” in a Presto Pressure Cooker in order to enclose it and control the temperature. In addition, he made openings in the pot for the dialyzing fluid. With the use of a vacuum on the dialysate leaving the pot, he was able to draw the excess water out of the patient’s blood. A blood pump was required to overcome resistance within the device.
This device was used clinically and when it was used in a closed circuit, the exact amount of fluid removed could be determined.

History As A Cure
December 1956 | Volume 8, Issue 1
Not long ago two teen-age boys in New York City got into trouble with the law. The police laid hands on them as juvenile delinquents, and in due course the boys appeared in court. Judge J. Randall Creel, of Magistrates’ Court, faced the tough problem that confronts jurists in such cases: should he send the boys off to jail forthwith, or should he see whether they might not be able to straighten themselves out? He decided on the latter course, and in looking for a means of rehabilitation he selected an unusual instrument: American history.
He gave these high school youngsters a historical research job to do.
They should forthwith (he told them) make a study of the Battle of Long Island—an important struggle in the Revolutionary War, in which General Washington’s army narrowly escaped destruction when the British commander, General Howe, landed an overpowering force on Long Island late in August of 1776. They would find, he suggested, that utter disaster for the American cause was averted because of a valiant rear-guard action fought by a regiment of the Maryland line. Let them, therefore, go to the sources and find out all they could about this action; having done this, each boy must submit a paper, describing what had happened, citing his sources, and bringing out what the gallant stand of the embattled Marylanders meant to future generations of Americans. By the jobs they did he would determine whether or not they had reinstated themselves as reliable junior members of their community.
The boys went to work, and eventually they presented their papers. They had done a good deal of hard work. They had traced the movements of the different troops engaged. They had run down the historic markers which (largely ignored by present-day citizens) show where the actions took place. They had found out all they could about the gallant old Maryland battalion, and they had gone to the trouble of listing the names and ranks of all the Marylanders who were killed or captured in the fight. And it seems that this excursion into American history had been a powerful medicine for good. These boys learned something—about their own home city (for they live in Brooklyn, and the battle they investigated had been fought along what are now the familiar streets and squares and parks of their own neighborhood), about the price a former generation had to pay for American freedom and happiness, and about the way in which boys of their own age, long ago, met a profound challenge.
Specifically: in their research into the history of the Battle of Long Island, these boys learned that a spirited rear-guard action by a regiment of Maryland soldiers—the 5th Maryland Infantry, under Colonel William Smallwood—had kept the American defeat from becoming a complete, irremediable disaster. The Marylanders fought a delaying action which enabled the bulk of Washington’s army to get away. Four or five hundred of them charged a British strong point, losing more than half of their numbers and going down at last to bloody defeat, but gaining the important fragments of time that enabled the beaten Continental army to get away clean and live to fight another day.
They found out that the Maryland soldiers who saved the day were simply boys like themselves. They dug out the old muster rolls, which gave each man’s name and age. Down the long columns, in faded archaic script, were the scanty records of boys who dared everything and gave everything more than a century and a half ago—and most of them turned out to be lads of eighteen or nineteen. This probably meant that they were even younger than that; boys usually add a year or two to their ages when they enlist in wartime. The Marylanders, in other words, were early teen-agers, who faced up to something big before they had got out of adolescence simply because youth wants nothing in all the world so much as the chance to respond to a real challenge. Life was good to them; it gave them the challenge, they met it—and today, as a direct result, we have an American nation.
One of the two boys, writing about the battle, expressed himself like this:
“If the youth of today is not conscious of the historical background of Long Island, the battle I will now unfold will make him so. I will, therefore, endeavor to show you what today’s youth could and should be capable of as compared to those who fought to preserve their rights as individuals. … It was merely lads of seventeen and eighteen who fought and died making this supreme sacrifice in defense of the preservation of the American Army and their fight for independence.”
The other boy, carried away by the story of the fight, found himself writing in the best vein of the military historian:
”…Thrice again these brave young Marylanders charged upon the house, once driving the gunners from their pieces within its shadow; but numbers overwhelmed them, and for twenty minutes the fight was terrible. Washington, Putnam and other General Officers who witnessed it … saw the overwhelming force with which their brave compatriots were contending, and held their breath in suspense and fear.… Washington wrung his hands, in the intensity of his emotion, and exclaimed: ‘Good God, what brave fellows I must this day lose!’” | <urn:uuid:ed5b147c-4b25-4679-953c-67169c32d06c> | http://www.americanheritage.com/content/history-cure |
A POTENTIALLY deadly and virulent bug that attacks the gut may soon be treated with the most stomach-churning of remedies.
A study published on Thursday in The New England Journal of Medicine has found transplanting human faeces into people with the superbug Clostridium difficile provided an almost universal cure for the condition - far outperforming traditional antibiotic treatment.
Faecal microbiota transplantation is thought to work by replacing the healthy bacteria in the gut that have been wiped out by antibiotics. For the past 20 years an Australian, Thomas Borody, has pioneered the treatment, although its use has been traced back thousands of years.
''This study is monumental,'' Professor Borody said.
The research found nearly 94 per cent of patients given the transplantation one or two times recovered, compared to only 30 per cent of the group given the antibiotic vancomycin.
The study was then stopped early by an ethics committee on the ground that it would be unethical not to offer all patients the transplants.
Professor Borody said C. difficile, which has ravaged the US, killing 30,000 people each year, was spreading to Australia, although no one could be sure how common it was as health departments did not routinely test for it.
''In Sydney we have had about 15 deaths that we know of … in the past year and a half,'' he said.
Just as people now donate blood, in future donors may be called on to give stools.
At present the faeces is inserted into the recipient using colonoscopy or nasal tube but researchers are developing a less off-putting method.
''The future of this FMT is filtered bacteria, washed, frozen and put in a capsule, which we lovingly call a 'crapsule','' said Professor Borody, from the Centre for Digestive Diseases and the University of Technology, Sydney.
The clinical associate dean at the St George Hospital clinical school at the University of NSW, Michael Grimm, said trying to find appropriate donors could be difficult.
''We are just starting now to grapple with the bacteria in the gut; it's an impossible soup to analyse,'' Professor Grimm said.
''What potential pathogens are in there that might not have been pathogenic to the host but could become pathogenic to the recipient, are really unknown.'' | <urn:uuid:18c1c0fa-c52e-42f8-a6be-2b76a45ab4ff> | http://www.goulburnpost.com.au/story/1242975/faeces-cure-for-deadly-bug/?cs=27 |
2. Physical Activity
Twenty-four RCT articles were reviewed for the effect of physical activity on weight loss, abdominal fat (measured by waist circumference), and changes in cardiorespiratory fitness (VO2 max). Thirteen articles were deemed acceptable (346, 363, 365, 369, 375, 401, 404, 406, 432, 434, 445-447). Only one of these RCTs compared different intensities and format with a control group, although the goal was to increase physical activity and not specifically to produce weight loss (401). Results from this trial were subsequently reported after 2 years, but these no longer included the control group (447). One additional study did not have a no-treatment control group but compared three active treatment groups with each other: diet only, exercise only, and combination exercise plus diet (448).
Most RCTs described the type of physical activity as cardiovascular endurance activities in the form of aerobic exercise such as aerobic dancing, brisk walking, jogging, running, riding a stationary bicycle, swimming, and skiing, preceded and followed by a short session of warmup and cool-down exercises. Some physical activity programs also included unspecified dynamic calisthenic exercises (363, 369, 406, 446).
The intensity of the physical activity was adapted to each individual and varied from 60 to 85 percent of the individual's estimated maximum heart rate, or was adjusted to correspond to approximately 70 percent of maximum aerobic capacity (VO2 max). The measure of physical fitness included VO2 max. The frequency of physical activity varied from three to seven sessions a week and the length of the physical activity session ranged from 30 to 60 minutes. Some physical activity programs were supervised, and some were home-based. Adherence to the prescribed physical activity program was recorded and reported in some studies and not mentioned in others. Most studies did not estimate the caloric expenditure from the physical activity or report calorie intake. The duration of the intervention varied from 16 weeks to 1 year; six articles reported on trials that lasted at least 1 year (346, 363, 375, 401, 406, 432).
Rationale: Twelve RCT articles examined the effects of physical activity, consisting primarily of aerobic exercise, on weight loss compared to controls (346, 363, 365, 369, 375, 401, 404, 406, 432, 434, 445, 446). Ten of the 12 RCT articles reported a mean weight loss of 2.4 kg (5.3 lb) (or 2.4 percent of weight) (363, 369, 375, 406, 419, 432, 434) or a mean reduction in BMI of 0.7 kg/m2 (2.7 percent reduction) (346, 365, 401) in the exercise group compared to the control group. In three of these ten studies, the weight loss was < 2 percent of body weight (< 2 kg) (4.4 lb) (369, 375, 434). In contrast, two RCTs showed no benefit on weight from exercise, reporting weight gain in the exercise group compared to the control group (445, 446). In one of these studies, the control group received only diet advice but nevertheless lost 9 kg (19.8 lb), whereas the exercise group lost only 7 kg (15.4 lb) (445). In the second study, there was a total of only 10 participants, all having noninsulin-dependent diabetes mellitus, and the control group lost 3 kg (6.6 lb) whereas the exercise group lost only 2 kg (4.4 lb) (446). A meta-analysis of 28 publications of the effect on weight loss of exercise compared to diet or control groups showed that aerobic exercise alone produces a modest weight loss of 3 kg (6.6 lb) in men and 1.4 kg (3.1 lb) in women compared to controls (449).
Ten articles reported on RCTs that had a diet-only group in addition to an exercise-only group (346, 363, 365, 369, 375, 406, 432, 434, 445, 448). In every case except one (365),the exercise-only group did not experience as much weight loss as the diet-only group. The diet-only group produced approximately 3 percent, or 3 kg (6.6 lb), greater weight loss than the exercise-only group.
No single study examined the length of the intervention in relation to the weight loss outcome. Only one study compared the effect on maximum oxygen uptake of different intensities and formats of physical activity over a 1-year follow-up (401) and 2-year follow-up period (447). Better adherence over 1 year was found if the exercise was performed at home rather than in a group setting, regardless of the intensity level. Subsequently, the different exercise groups were compared with each other over the longer term (2 years), and better long-term adherence was found in the higher intensity home-based exercise group compared to the lower intensity home-based or higher intensity group-based exercise groups (447).
The question of whether physical activity enhances long-term maintenance of weight loss has not been formally examined in RCTs. Examination of long-term weight loss maintenance produced by physical activity interventions compared with diet-only interventions cannot easily be compared between RCTs because of numerous differences between studies with respect to design, sample size, intervention content and delivery, and characteristics of the study population samples. However, a number of analyses of observational and post hoc analyses of intervention studies have examined whether physical activity has a beneficial effect on weight. Cross-sectional studies have generally shown that physical activity is inversely related to body weight (450-454) and rate of weight gain with age (455). Longitudinal studies with 2 to 10 years of follow-up results have observed that physical activity is related to less weight gain over time (456-459), less weight gain after smoking cessation in women (460), and weight loss over 2 years (461). In addition, post hoc analyses of several weight loss intervention studies reported that physical activity was a predictor of successful weight loss (454, 462, 463). The results of these RCTs showed that physical activity produces only modest weight loss and observational analyses from other studies suggest that physical activity may play a role in long-term weight control and/or maintenance of weight loss.
Rationale: Only three RCTs testing the effect of physical activity on weight loss also had measures of abdominal fat as assessed by waist circumference (365, 369, 375). One study demonstrated that physical activity reduced waist circumference compared with the control group (365), and another study showed a small effect on waist circumference (0.9 cm) in men but not women (375). One study in men showed a small increase in waist circumference (369). Weight loss was modest in all of these studies. These studies were not designed to test the effects of physical activity on abdominal fat independent of weight loss.
However, large studies in Europe (464), Canada (453), and the United States (465-468) reported that physical activity has a favorable effect on body fat distribution. These studies showed an inverse association between energy expenditure through physical activity and several indicators of abdominal obesity, such as waist circumference and waist-to-hip and waist-to-thigh circumference ratios.
Rationale: Eleven RCT articles testing the effect of physical activity alone on weight loss in men and women also included measures of cardiorespiratory fitness, as measured by maximal oxygen uptake (VO2 max) (346, 363, 369, 375, 401, 404, 406, 432, 434, 445, 446). All 11 showed that physical activity increased maximum oxygen uptake in men and women in the exercise groups by an average of 14 percent (ml/kg body weight) to 18 percent (L/min). Even in studies with modest weight loss (< 2 percent), physical activity increased VO2 max by an average of 12 percent (L/min) to 16 percent (ml/kg) (369, 375, 434).
One study that compared different formats and intensities of physical activity on VO2 max reported that improvement in VO2 max was related to adherence to the physical activity regime. In that study, the lower intensity program was equally effective on VO2 max as a higher intensity program, largely as a result of different levels of adherence (401).
The results of the RCTs strongly demonstrate that physical activity increases cardiorespiratory fitness in overweight and obese individuals. | <urn:uuid:512f125a-1c2b-4f1d-a1c5-4ccc50826a80> | http://www.nhlbi.nih.gov/guidelines/obesity/e_txtbk/methtri/3222.htm |

The Philadelphia Lazaretto: A Most Unloved Institution
In mid-July 1800, the U.S.S. Ganges, on the U.S. Navy’s earliest warships, encountered two American schooners, the Phebe and the Prudent, while navigating the Straits of Florida. These schooners held neither sugar cane nor corn but rather human cargo, 134 chained captives from West Africa to be exact, doomed for delivery to a notorious slave trader in Havana, Cuba. Commissioned with enforcing the newly-passed Federal Slave Trade Act that prohibited the transport of slaves by U.S. ships, Ganges Captain John Mullowny seized the Phebe and the Prudent, assigned prize crews to man both ships, and commanded them to sail north for Philadelphia. After a 1,500 mile, month long trip up the eastern coast of the United States, the crews arrived at the confluence of the Schuylkill and Delaware rivers with their recently confiscated cargo. Emaciated, exposed, and, surely disoriented, the scores of African survivors disembarked on Province Island, home to the Marine Hospital, a.k.a. the Philadelphia Lazaretto.
“The Ganges Africans” — the name bestowed upon them after many were given the surname Ganges — were part of one of the first slave trade violation cases confronted by the newly-established Federal judicial system. Their story exemplifies the ideological clashes that were occurring in the young nation and that would eventually boil over into the Civil War. Interestingly enough, at least two of the Ganges Africans would have extended stays in the Philadelphia area. One of them would become an indentured servant to Thomas Egger, the last quarantine master of the “old” Lazaretto on Province Island and the first one of the “new” Lazaretto in Tinicum Township, Delaware County. A second of the slaves was indentured to farmer Thomas Smith who had sold the property for the new facility to the Philadelphia Board of Health.
Moreover, their story reflects in miniature the history of the Philadelphia Lazaretto itself: integral to our nation’s demographic and political landscape and yet often overlooked. Stories like those of the Ganges Africans and the thousands of others who remain little-known or whose tales are untold are the reasons University of Pennsylvania historian David Barnes calls the Philadelphia Lazaretto a place “even rarer and more precious than New York’s [Ellis Island].”
Lazaretto seems an unusual name for a hospital in the American colonies. As it turns out, however, the word would become a common English term for isolation facilities and quarantine hospitals, ceasing to be a proper noun at all. As one might think, the term derives from the Italian, but its exact provenance is not completely clear. One theory holds that in 16th century Venice, the name of a local hospital, the Nazaretto, was combined with the name of Lazarus the Beggar from the New Testament. Professor Barnes notes that this theory is less plausible than the simpler, and generally accepted, thought isolation wards and quarantines came to be named for Lazarus the Beggar, patron saint of lepers. Regardless of its origin, it started to be applied to the “old” facility on Province Island built in 1743, though it was still referred to the Marine Hospital. The “new” Lazaretto, however, would never be called anything else.
At the end of the 18th century, politicians and doctors throughout the United States were passionately debating public health and quarantine issues, much as members of those same two professions debate health care policy today.
Thousands were falling victim to the effects of infectious diseases such as tuberculosis and yellow fever. The issue came to a head in 1793 after futile attempts to quarantine all ships arriving at the port of Philadelphia failed. A yellow fever epidemic of calamitous proportions broke out throughout the city. Within two months, the nation’s largest city and political and economic capital, lost more than a quarter of its population. Approximately 10% perished from yellow fever and another 17% fled the city.
After the 1793 epidemic, the city created a Board of Health to oversee conditions in the city. It found, among other things, that the old quarantine facility had failed terribly in preventing the propagation of yellow fever and other infectious diseases. Many authorities blamed this failure on its location only a few miles from the most densely populated parts of the city and thu, facilitating the interaction between infected patients and residents. Determined to prevent another calamity, The Board of Health constructed a new lazaretto ten miles south of Philadelphia in the isolated, uninhabited marshlands of Tinicum Township, Delaware County.
Construction of the Philadelphia Lazaretto finished in 1801, almost a century before the building of New York’s Ellis Island and San Francisco’s Angel Island. Upon completion, the Lazaretto was the first of its kind. It was a complex — both stately and state of the art — that, as The Philadelphia Public Ledger said in 1879, “might be mistaken for [the grounds of a] wealthy country gentleman....were it not for the yellow Quarantine flag.”
The central figure of the ten acre campus was the main hospital, an august Georgian, double-brick building that could house upwards of 200 patients at a given time. The campus also included the following: the Dutch hospital which was added in 1805 and was primarily used to house German immigrants afflicted with smallpox; the dead-house which was used for incinerating infected patients’ belongings; the barge houses which served as the waiting and sleeping quarters of the bargemen on duty during quarantine season; the residences of the chief physician and the quarantine master; and the government warehouse which stored the goods and merchandise of the quarantined vessels. These facilities and the sheer size of the campus made the Philadelphia Lazaretto a state-of-the-art hospital in comparison to its contemporaries. Remarkably, more than two centuries after their construction, the main hospital building and several other buildings remain intact and are rather well preserved.
During its years of operation from 1801 to 1893, the Philadelphia Lazaretto was certainly neither revered nor loved. As a matter of fact, sailors, merchants, and newly arriving immigrants dreaded and abhorred the sight of its flag — a yellow banner. It was, as University of Pennsylvania professor and the Philadelphia Lazaretto’s de facto historian David Barnes calls it, a most unloved institution. During the hospital’s near century of operation, the Philadelphia Lazaretto’s staff inspected and quarantined hundreds of thousands of merchant ships, much to the chagrin of businessmen and sailors. The hours, days, or even months at the Lazaretto meant the spoiling or confiscation of cargo and, in turn, the loss of significant capital. In addition to the loss of the merchants’ cargo, the Philadelphia Lazaretto was also the site at which sailors and immigrants perished. Many immigrants, much like the “Ganges Africans,” took their first steps on American soil. According to various estimates, a thirst of all Americans have an ancestor whose first contact with the New World was at the Lazaretto.
After closing its doors as a quarantine station in 1893, the site and the buildings went through several transformations. The Philadelphia Athletic Club purchased the site and renamed it the Orchard Club. The Orchard Club was a summer get-away for wealthy Philadelphians who used its prime waterfront location for leisure and recreation. There were several athletic clubs whos sponsored baseball teams during this era, and some even played their games on the grounds of the Lazaretto. These were not, however, the forerunners of the American League’s Philadelphia Athletics. After the closing of the Orchard Club, Colonel Robert Edward Glendinning — a substantial contributor to wartime aviation in the First World War — and George C. Thomas opened the Essington School of Flying in 1913. It was the state’s first water flying school and one of the first in the world.
Sadly, today the Philadelphia Lazaretto lies, mostly forgotten, in the same marshlands of Tinicum Township, Delaware County. Were it not for the tireless lobbying of a group of hard-working activists, the site may well have been destroyed. Though a township firestation was recently build on the northern half of the Lazaretto site, there is still much worthy of preservation. Similar projects, like New York’s restored Ellis Island and San Francisco’s Angel Island (in process), have given voice to the thousands and hundreds of thousands who came to these shores. The Friends of the Lazaretto and others are working hard to ensure that the rest of the site will stand as testament to the immigrants who landed in Philadelphia. | <urn:uuid:1487d9b6-9cee-445a-a4b7-b7784f0282ac> | http://www.ushistory.org/laz/news/pcbsummer10.htm |
Mount Desert Rock
About 20 miles southeast of Mount Desert Island, this is one of the most remote and lonely lights. Even mild storms scour the island, denuding it of anything not firmly secured, and frequently submerge it entirely. Yet each spring keepers transported soil from the mainland, tucking it into crevices on this otherwise barren rock in hopes of cultivating flowers and vegetables. For a few months in summer and early fall, the rock became a colorful garden in the middle of the sea. But late fall and winter storms always washed it all away. It's a challenge to see this lighthouse, even from a boat, but whale-watching cruises from Bar Harbor sometimes pass by.
Mount Desert Rock Lighthouse was built in 1830. | <urn:uuid:475d9a6c-8afd-4371-af7d-8a468e5542eb> | http://www.visitmaine.com/lighthouse/downeast/mount_desert_rock?font-size=10 |

Early Currency in China
With a history of over 3000 years, Chinese currency existed in both Ancient and Imperial China. In 1914, the Silver Dollar was established as the official currency of the Republic of China, with copper, fen, and nickel coins being added in the 1930s. During this time silver appreciated in value, and China could no longer retain the silver standard. In 1935, a new currency known as Fǎbì, was issued.
Introduction of the Gold Yuan and Chinese Yuan Renminbi
The Gold Yuan replaced the Fǎbì in 1948 at a rate of 1 Gold Yuan to 3 million Yuan Fǎbì. That same year, the Yuan Renminbi (often called RMB) was introduced as a way to help stabilize the Communist held areas of mainland China. In 1955, a re-evaluation took place and a new Yuan Renminbi was introduced at a rate of 1 new Yuan to 10,000 old Yuan.
The Renminbi in Foreign Exchange
During the command economy, the Chinese Yuan Renminbi was set to unrealistic exchange values and as a result, severe currency guidelines were put in place. When China's economy opened in 1978, the Yuan Renminbi was only used domestically and foreigners used exchange certificates; this led to a powerful black market. From 1997 to 2005, the Chinese government pegged the Chinese Yuan Renminbi to the US Dollar at approximately 8.3 CNY to 1 USD. In 2005, a flexible mechanism of exchange rates was phased in, with the RMB being re-evaluated to 8.1 Renminbi per US dollar. The Chinese government launched a pilot program in 2009, allowing some businesses in Guangdong and Shanghai to execute business and trade transactions with counterparties in Hong Kong, Macau, and select nations. The program has since expanded to all areas of China and all international counterparties. China has also made agreements with Australia, Japan, Thailand, Russia, and Vietnam to allow for direct currency trade, instead of converting to the US Dollar. As a managed float, the Renminbi's value is determined by a basket of foreign currencies.

Protractors - Innovation
While only one patent model for a protractor survives in the Smithsonian collections—from an inventor with a colorful personal history—several of the other objects also provide examples of technical innovation. For instance, some are manufactured versions of patented inventions. Others were named for the person with whom they were associated, even if that engineer or craftsman laid no claim to designing that protractor.
"Protractors - Innovation" showing 1 items.
- This brass semicircular protractor is divided by single degrees and marked by tens from 10° to 90° to 10°. It is attached with metal screws to a set of brass parallel rules. Brass S-shaped hinges connect the rules to each other. The bottom left screw on the parallel rules does not attach to the bottom piece. A rectangular brass arm is screwed to the center of the protractor. A thin brass piece screwed to the arm is marked with a small arrow for pointing to the angle markings. The protractor is stored in a wooden case, which also contains a pair of metal dividers (5-1/4" long).
- The base of the protractor is signed: L. Dod, Newark. Lebbeus Dod (1739–1816) manufactured mathematical instruments in New Jersey and is credited with inventing the "parallel rule protractor." He served as a captain of artillery during the Revolutionary War, mainly by making muskets. His three sons, Stephen (1770–1855), Abner (1772–1847), and Daniel (1778–1823), were also noted instrument and clock makers. The family was most associated with Mendham, N.J. (where a historic marker on N.J. Route 24 indicates Dod's house), but Dod is known to have also lived at various times in Newark.
- ID number MA*310890 is a similar protractor and parallel rule.

Philippa Ryan, Scientist, British Museum
Archaeobotany is the study of ancient plant remains, and I joined the field team at Amara West in Sudan earlier this year to collect samples for archaeobotanical analysis. Charred plant materials were retrieved on-site from sediments through dry-sieving and flotation. These samples were subsequently brought back to the British Museum for further sorting and identification.
At the moment I am analysing the charred seeds and fruits with Caroline Cartwright, who is also analysing the wood charcoal. The macroscopic plant remains are analysed using both a stereo microscope and a SEM (scanning electron microscope). Charred remains found so far include cereal grains (wheat and barley) and crop-processing waste, fruits such as figs and a wide range of wild plants.
I am also processing sediment samples to extract phytoliths (microscopic plant remains), which are formed when soluble silica taken up in groundwater by plants is deposited within and between certain plant cells. These silicified cells are found within many different plant families such as grasses (which include cereals), sedges and palms.
Phytoliths are difficult to identify, but have the advantage of surviving in both charred and non-charred contexts, so we can learn about the presence and use of plants in areas where seeds and grains don’t survive.
At the moment, I am processing sediments to extract phytoliths, which includes the removal of carbonates, clays, organics, other remaining non-siliceous material through heavy liquid flotation, and finally mounting dried phytoliths onto slides. Phytoliths are then identified and counted using an optical (light) microscope.
Analysis of these different types of plant remains helps us learn about the past uses of plants at Amara West in day-to-day life, such as for food, fuel and animal fodder. I am also looking at the distributions of seeds and phytoliths across the site to examine locations of plant based activities such as food processing, as well as whether there are any differences in diet between poorer and richer households, or across the history of the site.
Plant remains can also help to provide information about the nearby vegetation, for instance the types of grasses, wetland plants and trees that grew near the ancient town. | <urn:uuid:35d563a2-5f98-4723-8212-690077a85293> | http://blog.britishmuseum.org/2011/08/16/back-in-the-lab-archaeobotany-from-amara-west/?like=1&source=post_flair&_wpnonce=4e28c04ab9 |
Many of us are inclined not to talk about things that upset us. We try to put a lid on our feelings and hope that saying nothing will be for the best. But not talking about something doesnt mean we arent communicating. Children are great observers. They read messages on our faces and in the way we walk or hold our hands. We express ourselves by what we do, by what we say, and by what we do not say.
When we avoid talking about something that is obviously upsetting, children often hesitate to bring up the subject or ask questions about it. To a child, avoidance can be a message - If Mummy and Daddy cant talk about it, it really must be bad, so I better not talk about it either. In effect, instead of protecting our children by avoiding talk, we sometimes cause them more worry and also keep them from telling us how they feel.
On the other hand, it also isnt wise to confront children with information that they may not yet understand or want to know. As with any sensitive subject, we must seek a delicate balance that encourages children to communicate - a balance that lies somewhere between avoidance and confrontation, a balance that isnt easy to achieve. It involves:
- trying to be sensitive to their desire to communicate when theyre ready
- trying not to put up barriers that may inhibit their attempts to communicate
- offering them honest explanations when we are obviously upset
- listening to and accepting their feelings
- not putting off their questions by telling them they are too young
- trying to find brief and simple answers that are appropriate to their questions; answers that they can understand and that do not overwhelm them with too many words.
Perhaps most difficult of all, it involves examining our own feelings and beliefs so that we can talk to them as naturally as possible when the opportunities arise.
Not Having All the Answers
When talking with children, many of us feel uncomfortable if we dont have all the answers. Young children, in particular, seem to expect parents to be all knowing - even about death. But death, the one certainty in all life, if lifes greatest uncertainty. Coming to terms with death can be a lifelong process. We may find different answers at different stages of our lives, or we may always feel a sense of uncertainty and fear. If we have unresolved fears and questions, we may wonder how to provide comforting answers for our children.
While not all our answers may be comforting, we can share what we truly believe. Where we have doubts, an honest, I just dont know the answer to that one, may be more comforting than an explanation which we dont quite believe. Children usually sense our doubts. White lies, no matter how well intended, can create uneasiness and distrust. Besides, sooner, or later, our children will learn that we are not all knowing, and maybe we can make that discovery easier for them if we calmly and matter-of-factly tell them we dont have all the answers. Our non-defensive and accepting attitude may help them feel better about not knowing everything also.
It may help to tell our children that different people believe different things and that not everyone believes as we do, e.g., some people believe in an afterlife; some do not. By indicating our acceptance and respect for others beliefs, we may make it easier for our children to choose beliefs different from our own but more comforting to them.

Oct. 3, 2011 -- Children who are overweight compared to their peers are nearly three times more likely to have high blood pressure, a new study shows.
The study, published in the journal Hypertension, followed 1,111 school-aged children in Indiana for an average of four years.
Twice each year, researchers visited schools to take blood pressure measurements and record the kids’ heights and weights.
About 40% of the children in the study were above the 85th percentile on growth charts for their height and weight. When children are above the 85th percentile, doctors consider them to be overweight.
Among the overweight kids, 14% had blood pressure that was higher than normal, while only 5% of normal-weight kids had elevated blood pressure.
The study also found that extra pounds are especially dangerous for kids who are already big.
"For an overweight and obese child, if you increase your BMI [body mass index] percentile a little bit, that would increase your blood pressure strongly,"says researcher Wanzhu Tu, PhD. Tu is a research scientist at Regenstrief Institute and professor of biostatistics at Indiana University School of Medicine, both in Indianapolis.
"In the same way," Tu says, for just a little bit of weight loss "you could benefit greatly in terms of blood pressure."
The risks of overweight were the same, regardless of the child’s sex or race. About 42% of the kids in the study were black.
Pediatricians say the study is wake-up call.
"We’ve tended to look at the overweight category as a lower-risk category," says Stephen R. Daniels, MD, PhD, chairman of the department of pediatrics at the University of Colorado School of Medicine in Denver. He was not involved in the research.
"This suggests to me that we really need to worry about kids who are in that overweight category," says Daniels, who is also pediatrician-in-chief at Colorado Children’s Hospital.
Other experts say the findings are concerning because having high blood pressure has been shown to set kids up for health complications.
Not only are children with high blood pressure much more likely to turn into adults who have high blood pressure, but newer studies have shown that kids can get the same kinds of organ damage -- to the heart, blood vessels, and kidneys -- that doctors once thought was only a problem for adults with the condition.
One study even found that kids with high blood pressure have subtle changes in the brain area that controls attention, problem solving, and working memory.
"For physicians, we have to take much more seriously this concept of the childhood origins of adult diseases and look beyond the weight and beyond the blood pressure level because we’re finding more evidence, subtle evidence, of injury," says Bonita Falkner, MD, professor of medicine and pediatrics at Thomas Jefferson University in Philadelphia.
"So it’s not going to be a risk that’s going to be in the future. It’s a risk that’s now," says Falkner, who wrote an editorial on the study, but was not involved in the research.
"It jacks up the concern about preventing childhood obesity and also not waiting until they are obese," she tells WebMD. "Even overweight can be problematic for children."

Viator,Vol. 37 (2006)
In 772, shortly after annexing his brother’s share of the Frankish kingdom, Charlemagne launched his first campaign against the Saxons. “No war taken up by the Frankish people was ever longer, harder or more dreadful,” wrote Einhard almost half a century later. For more than three decades (from 772 until 804) Charlemagne and his army were occupied with a bloody and protracted attempt to pacify and subdue the Saxons.
A standard textbook narrative of the Saxon wars would go roughly like this: Charlemagne’s successful raid into Saxony in 772 opened the first phase of the Saxon wars. The reasons behind it are not at all clear. The so-called Annales regni Francorum, that is, the supposedly official court-based Frankish history, simply state that from Worms, where Charlemagne had held an assembly, he marched into Saxony. No Saxon rebellion or any other Saxon aggression are mentioned in connection with the Frankish attack, and it seems that once Charlemagne had managed to pacify Aquitaine, he decided to finish the job his father had already started in Saxony. Following the capture of Eresburg, Charlemagne and his army continued northwards, destroying on their way the enigmatic Irminsul. Charlemagne would have liked to continue his campaign in Saxony, but a desperate call for help from the pope forced him to leave Saxony and head southwards. The Saxon reaction was not late in coming. When Charlemagne and the Frankish army were busy in Italy, the Saxons invaded Hesse, plundering and destroying everything on their way. | <urn:uuid:826d4a3e-84a3-4b3d-a732-365388cdd322> | http://www.medievalists.net/2013/01/03/charlemagnes-jihad/ |

Fracking is short for ‘hydraulic fracturing,’ a term used to describe the process of pumping millions of gallons of pressurized water, sand and chemicals down a newly drilled well to blast out the surrounding shale rock and gas.
It’s a relatively new technique that‘s made shale gas more popular in recent years. For a long time, shale gas — a natural gas that’s embedded in ancient rocks known as shale — was deemed as being not worth the trouble by drilling companies because it was so difficult to recover. The gas is embedded in rocks and the best way to get it out is to drill in sideways, which only became possible in the 1980s and 1990s as the gas industry improved its directional drilling technology. Later, technological advances that let drillers use more water pressure made fracking into an economically viable option for obtaining shale gas from the rocks.

Shale is scattered throughout the United States. The two hottest shale sites in America right now are the Barnett Shale in Texas and the Marcellus shale, which is buried beneath seven states and part of Lake Erie. Other large shale deposits are located in Arkansas, Louisiana, New Mexico, Oklahoma and Wyoming.
Despite its potential, though, a movement has welled up lately to block the shale gas boom. Some critics say embracing natural gas so heartily will slow the rise of renewable energy, but the biggest beef with shale isn't as much about its gas — it's about how we get it out of the ground. Shale gas would likely still be a novelty fuel without modern advances in hydraulic fracturing, yet the need for fracking is also starting to seem like it could be shale's fatal flaw. The practice has sparked major environmental and public heath concerns near U.S. gas fields, from diesel fuel and unidentified chemicals in groundwater to methane seeping out of sink faucets and even blowing up houses. | <urn:uuid:75db20fa-e3dc-4304-905b-a8885026ad81> | http://www.mnn.com/eco-glossary/fracking?page=3 |

Swine-origin influenza A H1N1 update
As swine-origin influenza A H1N1 continues to spread through the world, with cases in Asia and Africa, WHO is now debating whether to declare a pandemic.
Since the start of May, the number of H1N1 cases has risen from fewer than 3000 to over 20 000. As of June 8, 25 288 people had been infected, of whom 139 have died.
A key concern was the spread of the virus to developing countries, which will struggle to contain the virus. Africa's first infection was in a young girl travelling back to Egypt fro ...

I am trying to understand what is the difference between TCP Half Open Connection and TCP Half closed connection can any one tell what exactly are they?
When TCP establishes a connection, it is considered guaranteed since there is a handshake that takes place:
At that point the connection is established, and data begins to flow. In contrast, a UDP packet is not guaranteed, and is just sent in the hopes it gets there.
Officially, according to the RFC's, a half-open TCP connection is when one side of the established connection has crashed, and did not send notification that the connection was ending. This is not the common usage today.
Unofficially, if can refer to an embryonic connection, which is a connection in the process of being established.
Half-closed is the opposite of that unofficial definition. It is a state somewhere in the middle where the computers are tearing down the established connection. | <urn:uuid:d3c44a8d-eefb-4ab4-882f-6409ae560258> | http://superuser.com/questions/298919/what-is-tcp-half-open-connection-and-tcp-half-closed-connection |

Our moods change when we hear music, but not all music affects us the same way. Slow, soft, higher-pitched, melodic songs soothe us; upbeat classical music makes us more alert and active; and fast, harsh, lower-pitched, dissonant music can rev us up and stress us out. Why would certain sounds affect us in specific emotional ways? One possibility is because of an overlap between how we perceive music and how we perceive human voice. Across human languages, people talk to their babies in slower, softer, higher-pitched voices than they speak to adults. And when we’re angry, we belt out low-pitched growly tones. The specific vocal attributes that we use in different emotional contexts are specific to our species… So what makes us so egocentric to think that other species might respond to our music in the same ways that we do?

Cotton-top tamarins are squirrel-sized monkeys from northern Colombia that are highly social and vocal. As in humans (and pretty much every other vocalizing species studied), they tend to make higher-pitched tonal sounds when in friendly states and lower-pitched growly sounds when in aggressive states. But tamarin vocalizations have different tempos and pitch ranges than our tempos and pitch ranges.
Chuck and David musically analyzed recorded tamarin calls to determine the common attributes of the sounds they make when they are feeling friendly or when they are aggressive or fearful. Then they composed music based on these attributes, essentially creating tamarin happy-music and tamarin death metal. They also composed original music based on human vocal attributes. They played 30-second clips of these different music types to pairs of tamarins and measured their behavior while the song was being played and for the first 5 minutes after it had finished. They compared these behavioral measures to the tamarins’ behavior during baseline periods (time periods not associated with the music sessions).
An example of happy tamarin music (Copyright by David Teie and available through Biology Letters) can be found here.
An example of aggressive tamarin music (Copyright by David Teie and available through Biology Letters) can be found here.As the researchers had predicted, tamarins were much more affected by tamarin music than by human music. Happy tamarin music seemed to calm them, causing the tamarins to move less and eat and drink more in the 5 minutes after the music stopped. Compared to the happy tamarin music, the aggressive tamarin music seemed to stress them out, causing the tamarins to move more and show more anxious behaviors (like bristling their fur and peeing) after the music stopped.
The tamarins also showed lesser reactions to the human music. They showed less anxious behavior after the happy human music played and moved less after the aggressive human music played. So, human voice-based music also affected the tamarins to some degree, but not as strongly. This may be because there are some aspects of how we communicate emotions with our voice that are the same in tamarins. (How did the tamarin music make you feel?)
Can you imagine what we could do with this idea of species-specific music? Well, David and Chuck did! They have since developed music for cats using similar techniques. Although they're still working on the paper, they have said that the cats prefered and were more calmed by cat music compared to human music. You can find samples and get your own copies here.
We often think of vocal signals conveying messages in particular sounds, like words and sentences. But calls seem to do much more than that, making the emotions and behaviors of those listening resemble the emotions of those calling.

The Edupunks' Guide: How to Do Research Online
It’s the best of times and the worst of times to be a learner. College tuition has doubled in the past decade, while the options for learning online and independently keep expanding. Anya Kamenetz's new free ebook The Edupunks’ Guide is all about the many paths that learners are taking in this new world, and we're running excerpts from the book all week. We're also asking GOOD readers to doodle your learning journey and submit the result by Sunday, September 11.
There’s been a revolution in the way people spread knowledge. Sharing information openly over the Internet is way cheaper than purchasing it commercially in dead-tree format, and often the learning that happens this way is faster, more up-to-date, and more relevant to our immediate needs. A simple example is learning to make pizza. A few years ago, you may have had to take a class or at least buy a cookbook. Today you can put “how to make a pizza” into YouTube and within minutes, you’re watching a video that shows you how to fling the dough!
More and more people around the world are building on this knowledge revolution to explore new modes of learning and to transform what we mean by “education.”
For many, the first step in an online learning journey is a simple Google search.
- Start with Google, the most-used search engine on the web. Put your phrase in quotes to return pages with the exact words, like this: “African-American history”
- Search on Wikipedia to get an overview of the topic. Follow the links to an article’s sources at the bottom of the page.
- Google Scholar will give you scholarly journal articles and other verified sources of information.
- An online archive like The Internet Archive may offer original source material.
- YouTube is good for videos—a quick entry into a topic. Or just Google your phrase and the word “video.”
- For news stories, try Google News
- For links on news, trends, and up-to-the-minute happenings, you can search Twitter with a hashtag, like this: #americanidol.
- Try posting your question to a site like OpenStudy or WikiAnswers.
- Put in your search terms plus the word “forum” or “blog” to see what ideas other people have discussed on message boards or on blogs.
A successful online research session will leave you with 20 open tabs or windows at the top of your screen. Follow your curiosity, but keep track of the links you’re following in an email draft, Word document, or an application like Evernote or Diigo so you can consult them later.

Simple technique appears to be safe and effective, review suggests
By Robert Preidt
MONDAY, Oct. 15 (HealthDay News) -- A technique called the "mother's kiss" is a safe and effective way to remove foreign objects from the nostrils of young children, according to British researchers.
In the mother's kiss, a child's mother or other trusted adult covers the child's mouth with their mouth to form a seal, blocks the clear nostril with their finger, and then blows into the child's mouth. The pressure from the breath may expel the object in the blocked nostril.
Before using it, the adult should explain the technique to the child so that he or she is not frightened. If the first attempt is unsuccessful, the technique can be tried several times, according to a review published in the current issue of the CMAJ (Canadian Medical Association Journal).
For their report, researchers in Australia and the United Kingdom examined eight case studies in which the mother's kiss was used on children aged 1 to 8 years.
"The mother's kiss appears to be a safe and effective technique for first-line treatment in the removal of a foreign body from the nasal cavity," Dr. Stephanie Cook, of the Buxted Medical Centre in England, and colleagues concluded. "In addition, it may prevent the need for general anesthesia in some cases."
Further research is needed to compare various positive-pressure techniques and test how effective they are in different situations where objects are in various locations and have spent different lengths of time in the nasal passages, the researchers noted in a journal news release.
The U.S. National Library of Medicine has more about foreign objects in the nose.

Some unknown terrible person shot a defenseless pilot whale last month, leaving it to swim the Atlantic in agony for weeks before it finally beached itself on the New Jersey shore and died. Authorities are still looking for the shooter. The bullet wound caused a fulminant infection in the whale’s jaw that prevented it from eating, so it basically starved to death. This was determined during a necropsy, an autopsy for animals.
Along with sympathy for the poor creature, this debacle aroused an interesting question: How does one autopsy a whale? With four-ton meat hooks, whaling knives and bone saws, actually. Michael Moore, a veterinarian and whale biologist at the Woods Hole Oceanographic Institution, does it all the time.
Moore spends much of his time studying North Atlantic right whales, an endangered species whose name derives from whalers’ adage that these were the “right whales” to hunt, because they’re easy to spot and float when they die. They’re no longer hunted for their oil, but they are entangled in fishing lines and injured in ship collisions, often suffering for a great while and also succumbing to starvation. “It’s the most egregious animal welfare issue globally at this time,” in Moore’s words. But protecting them requires understanding how they died, and to do this Moore must take them apart, studying their broken bones and lobster net-tangled flukes to determine their exact causes of death.In partnership with the National Oceanic and Atmospheric Administration, Moore deploys on-call, toting a case full of knives to examine right whales that have beached or are floating in the open ocean. Right whales are baleen whales and at least two orders of magnitude bigger than the toothed pilot whale that was shot, so in most cases, they must be examined right where they‘re found — that means on the beach. They either beach themselves and die there, or they’re towed to shore once they have been located at sea.
Moore and other rubber-suited biologists work amid 120,000 pounds of slick black-and-red whale flesh, clambering over and through the carcass to find out what went wrong. Time is of the essence, because the longer they wait, the more the animal’s internal organs break down, making it difficult to determine how it died.
Moore uses a Japanese whaling hook, which is useful for pulling back sheets of blubber to get at the animal’s internal organs. He carries a bone saw — formerly his mother’s — to get through jaws and vertebrae to find the location of a fatal injury. He’s even visited indigenous Alaskan tribes to study their ancestral whale processing techniques.
The pilot whale that died was small, so it was trucked to a necropsy facility at the the Marine Mammal Stranding Center in Brigantine, N.J., down the shore north of Atlantic City. It weighed about 740 pounds when it beached, quite gaunt for an animal that should normally weigh more than a ton. Researchers knew something was seriously wrong, but they had to perform a necropsy to determine what it was.
The creatures are brought in on trucks and hoisted into the facility on chains rigged to the ceiling, attached to four-ton-rated meat hooks. They lay on negative-pressure steel tables, the same types used in human autopsy procedures, which suck out odors and pathogens as the biologists get to work. The lab also contains deep freezers for stringing up deceased animals; it harbors an overwhelming odor of chemical and organic substances. (It’s somewhat legendary at WHOI that Moore lost his sense of smell while in veterinary school, which he says enables him to get literally inside a rotting animal carcass without losing his lunch or his cool.)
The 11-foot-long pilot whale died shortly after authorities reached its side on the beach on Sept. 24. But it wasn’t until a necropsy a couple weeks later that they knew what happened. The bullet entered near its blow hole, but the wound had closed and faded a bit, suggesting it had been shot about a month prior. The .30-caliber round lodged in its jaw, causing the infection.
“This poor animal literally starved to death,” said Bob Schoelkopf, co-director of the Marine Mammal Stranding Center, in an interview with the AP. “It was wandering around and slowly starving to death because of the infection. Who would do that to an innocent animal?”
That question is now in the hands of the authorities. For biologists like Moore and Schoelkopf, necropsies can at least answer the question of how. Why, of course, is something else entirely.

Narrator: This is Science Today. A new air sampler, which can effectively trap and evaluate fine particle pollutants in both their solid and gas phases has been developed by scientist Lara Gundel of the Lawrence Berkeley National Laboratory. This sampler can greatly impact future EPA air quality standards and lead to a definitive understanding of how pollutants such as polycyclic aromatic hydrocarbons and pesticides, affect our health.
Gundel: I guess the innovations we made were a way to separate the gases and particles accurately and then to be able to collective measure particles and the gases separately and accurately.
Narrator: Gundel achieved this by coating an inner tube of roughened glass inside the filter with sticky resin beads, which were finely ground up until their pores were small enough to trap gas particles.
Gundel: We quickly decided that this new technology that we had, these new kinds of sampler designs, could be used in outdoor air, in general atmospheric questions.
Narrator: Gundel is currently collaborating with other scientists and the EPA to test this sampler at various sites across the country. For Science Today, I'm Larissa Branin. | <urn:uuid:8a346dd2-3a3a-47c9-99e2-26e162d036a7> | http://www.ucop.edu/sciencetoday/article/1281 |

Sustainability and Renewable Merino
Wool runs on grass
The primary inputs for wool production are water, sunshine and fertile soils to grow grass – the primary diet of sheep.
As such merino production inherently has the potential of being fully sustainable providing it is operated within the carrying capacity of the ecosystem.
They must operate, or be in the process of implementing, a grazing management strategy based on long term sustainability.
The management system must embrace holistic farming principals with the goal of developing a resilient ecosystem that can regenerate, withstand stress and rebuild itself when necessary.
This goal should be to aim for 100% ground cover all year, with a focus on perennial grasses to regenerate the ecology and increase biodiversity.
Holistic farming principles include:
- Clear goals for the people involved
– Clear goals for the land in use
– Clear goals for the business
- Clear goals for the management of livestock
The management process should involve:
- Reviewing these strategies regularly
– Making decision with these goals in mind
– Monitoring the health of your land, your business and the people involved | <urn:uuid:cac13ba5-da9c-4b7d-a7d7-8bdb919fb48d> | http://newmerino.com.au/wp/land-management/ |

blended with decaf ceylon tea, natural peach flavor, marigold flowers, apple pieces and apricots
Cultivation of peaches began in China as early as 2000BC. The winds of trade brought peaches to Greece and Persia, where they were instantly accepted. The juicy fruit was also a big hit with the Romans, who cultivated it throughout the empire. From Italy, peaches made the leap across the Atlantic, where early settlers planted them throughout the East Coast. Soon they were so plentiful, local botanists thought of them as native fruits. | <urn:uuid:4aada9d1-6c65-4ada-a5fb-ea8a77ace234> | http://www.adagio.com/decaf/decaf_peach.html |
OFF THE CHARTS
Oil supply rising, but demand may more than keep pace
Published: Saturday, November 24, 2012 at 4:36 p.m.
Last Modified: Saturday, November 24, 2012 at 4:36 p.m.
It used to be taken for granted that as economies grew, they would use more oil. That was a major reason cited in warnings that the world would run out of oil, particularly if standards of living rose in developing countries.
Well, standards of living are improving in developing countries, but the dire forecasts now appear to be wrong. In part that is because new discoveries and improving technologies have increased the amount of oil that can be produced. It also reflects conservation, in part, as cars become more efficient and as other steps are taken to reduce oil use.
The International Energy Agency, in its 2012 World Energy Outlook, released last week, forecast that U.S. oil production, which began to rise in 2009 after decades of decline, would continue rising through at least 2020, when it could be about as high as it was in 1970, the year of peak production.
At the same time it forecast that by 2035, U.S. oil consumption, which peaked in 2005, could decline to levels not seen since the 1960s, depending on how much conservation is encouraged.
The IEA report also forecast that by around 2020, the United States could surpass Saudi Arabia as the world's largest oil producer, and that while the country was not likely to become a net exporter of oil, the North American continent as a whole could be by around 2030.
But despite declining demand in some countries that historically were heavy users of oil, the world demand for oil seems likely to continue to rise. The IEA forecast that global energy demand – including demand for energy produced by other sources – is likely to rise by 35 percent by 2035, with a large part of the increase coming from China and India.
In 1969, the United States consumed a third of the oil used in the world, while China used less than 1 percent. Last year the U.S. share was less than 22 percent, while the Chinese accounted for 11 percent. The IEA forecasts that by 2030, the U.S. share could be less than the Chinese one.
By 2035, U.S. consumption of oil is expected to be as much as one-third less than it was last year. In China, oil consumption is expected to be up as much as two-thirds from the 2011 level, and India's is predicted to more than double.

Aswan High Dam on the Nile River
Aswan-- On 15 January 1971, Egypt celebrated the completion of the High Dam, whose funding was the center of a Cold War dispute that led to the 1956 Suez War. Located on the Upper Nile, around 1000km downstream from Cairo, the gigantic mountain of concrete and steel is among the 20th century's most elaborate engineering work. Aswan High Dam on the Nile River is located at the north end of Lake Nasser.
The construction of the High Dam began in 1960, and it was officially inaugurated ten years later, at a cost of US$1 billion, much of which was provided by the former Soviet Union. The dam stores 160 billion cubic meters of water, and the reservoir behind it, named Lake Nasser, stretches some 350km into Egypt and 150km into Sudan. It is a symbol for Egyptians patience and challenge.
The Suez Crisis began on 26 July 1956 when Egyptian President Gamal Abdel Nasser nationalised the Suez Canal. The move was in response to a decision by the United States and Britain to withdraw finance for the Aswan High Dam - a massive project to bring water to the Nile valley and electricity to develop Egypt's industry - because of Egypt's political and military ties to the Soviet Union.
The world-famous High Dam was an engineering miracle when it was built in the 1960s. Today it provides irrigation and electricity for the whole of Egypt and, together with the old Aswan Dam, 6km downriver, wonderful views for visitors. From the top of the two mile-long High Dam you can gaze across Lake Nasser, the huge reservoir created when it was built to Kalabsha temple in the south and the huge power station to the north.
The story of the High Dam was a tale of a nation, hikayit sha‘b, as Abdel Halim Hafiz chanted in an iconic song from the Nasserist period.
This nation lived under the yoke of British colonialism for over 70 years. After gaining independence, Egypt's revolutionary president, Colonel Gamal Abdel Nasser, approached the World Bank to finance the construction of a dam on the Nile, a vital step towards economic development. The World Bank refused. In an audacious challenge to old and new imperialism, Nasser nationalized the Suez Canal in 1956 to acquire funding for the project. The struggling nation heroically endured subsequent military assaults and a trade embargo. The dam was eventually built.
The story of the High Dam at Aswan is indeed the tale of this nation. The stages of its history chronicle critical transformations in Egyptian history at large. During the last half century, the dam moved from being a celebrated monument to Egyptian independence to a forgotten barrage deep in the country's south. It was a state-engineered tool of anti-imperialist propaganda, whose splendor faded away with the downfall and fundamental reversion of the anti-imperial project.
In other words Egypt had monopoly of the waters. On behalf of its colonial possessions - Sudan, Kenya, Tanzania and Uganda - Britain, which was primarily concerned with the Suez Canal and the passage to India, signed away their most precious resource.
Egypt had the right to veto any project along the Nile and full rights of inspection.
In 1959, this deal was overtaken by a new agreement between Egypt and Sudan splitting the waters 75 per cent to 25 per cent and guaranteeing Cairo "full control of the river".
The results of this control are nowhere more clearly seen than at Lake Nasser, a man-made reservoir 550km-long, created when Egypt completed the Aswan high dam. The country's largest engineering project took six years to build and another five years to fill.
Some 55.5 billion cu m of water gush from the Aswan dam into Egypt annually. It has enabled Cairo to regulate the life-giving annual flood, to irrigate its otherwise parched landscape, and at the point it was finished supplied half the country's electricity needs.
Nasser was in need of a success, a success to rival that of the Suez Canal, which is a 190 km-long man-made waterway linking the Mediterranean with the Red Sea. The French dug the Suez Canal 97 years before Nasser took the decision to nationalize it. Nasser took the decision to nationalize the Suez Canal just two years before it was supposed to revert back to Egyptian control. This was used as justification by three countries [Britain, France and Israel] to launch a tripartite strike against Egypt. The President's decision to cancel the contract just two years before its expiry date made it seem like Nasser was seeking a popular confrontation.
The difference is that the Aswan High Dam is a success story, whereas the Suez Canal was a story of conflict. The High Dam is a witness of the history of Egypt's relationship with the Soviet Union, which continued throughout Nasser's rule. The Aswan High Dam is considered to be the most important construction of the Nasser regime.
Abu Simbel, Egypt — In the 1960s, rising waters from a new dam threatened to submerge the temples and monuments of Nubia, the ancient home of black pharaohs in Egypt's far south. To preserve them, the antiquities were dismantled, moved and reconstructed. Today, most of the surviving monuments can be seen only from the lake created by the waters that nearly destroyed them.
A short flight from Aswan is Abu Simbel and the Great Temple of Ramses II, and the gods of creation and light, Ptah, Amen and Heru-khuti is the most iconic Ancient Egyptian sight after the Pyramids. The temple has four massive statues of Ramses II and the gods Ra-Horakhty, Amun and Ptah at its entrance. Beyond lie two pillared halls and the sacred sanctuary. Every wall and ceiling is a storybook art gallery of this extraordinary pharaoh's life. (He lived to 90 and is said to have fathered more than 200 children).

Construction of the high dam was an enormous national project that every Egyptian contributed to. Nubians in particular sacrificed their possessions, including 45 Nubian villages lying on 300 square kilometers of land and one million palm trees. They were moved from a paradise on the banks of the Nile. These treasures are all submerged under water now. Along with the loss of the land, there was also the loss of heritage, values, memories and lifestyle, and, above all proximity to the water, the primary source of life.

|RNA expression pattern|
c-Met (MET or MNNG HOS Transforming gene) is a proto-oncogene that encodes a protein known as hepatocyte growth factor receptor (HGFR). The hepatocyte growth factor receptor protein possesses tyrosine-kinase activity. The primary single chain precursor protein is post-translationally cleaved to produce the alpha and beta subunits, which are disulfide linked to form the mature receptor.
MET is a membrane receptor that is essential for embryonic development and wound healing. Hepatocyte growth factor (HGF) is the only known ligand of the MET receptor. MET is normally expressed by cells of epithelial origin, while expression of HGF is restricted to cells of mesenchymal origin. Upon HGF stimulation, MET induces several biological responses that collectively give rise to a program known as invasive growth.
Abnormal MET activation in cancer correlates with poor prognosis, where aberrantly active MET triggers tumor growth, formation of new blood vessels (angiogenesis) that supply the tumor with nutrients, and cancer spread to other organs (metastasis). MET is deregulated in many types of human malignancies, including cancers of kidney, liver, stomach, breast, and brain. Normally, only stem cells and progenitor cells express MET, which allows these cells to grow invasively in order to generate new tissues in an embryo or regenerate damaged tissues in an adult. However, cancer stem cells are thought to hijack the ability of normal stem cells to express MET, and thus become the cause of cancer persistence and spread to other sites in the body.
MET proto-oncogene (GeneID: 4233) has a total length of 125,982 bp, and it is located in the 7q31 locus of chromosome 7. MET is transcribed into a 6,641 bp mature mRNA, which is then translated into a 1,390 amino-acid MET protein.
MET is a receptor tyrosine kinase (RTK) that is produced as a single-chain precursor. The precursor is proteolytically cleaved at a furin site to yield a highly glycosylated extracellular α-subunit and a transmembrane β-subunit, which are linked together by a disulfide bridge.
- Region of homology to semaphorins (Sema domain), which includes the full α-chain and the N-terminal part of the β-chain
- Cysteine-rich MET-related sequence (MRS domain)
- Glycine-proline-rich repeats (G-P repeats)
- Four immunoglobulin-like structures (Ig domains), a typical protein-protein interaction region.
A Juxtamembrane segment that contains:
- a serine residue (Ser 985), which inhibits the receptor kinase activity upon phosphorylation
- a tyrosine (Tyr 1003), which is responsible for MET polyubiquitination, endocytosis, and degradation upon interaction with the ubiquitin ligase CBL
- Tyrosine kinase domain, which mediates MET biological activity. Following MET activation, transphosphorylation occurs on Tyr 1234 and Tyr 1235
- C-terminal region contains two crucial tyrosines (Tyr 1349 and Tyr 1356), which are inserted into the multisubstrate docking site, capable of recruiting downstream adapter proteins with Src homology-2 (SH2) domains. The two tyrosines of the docking site have been reported to be necessary and sufficient for the signal transduction both in vitro.
MET signaling pathway
MET activation by its ligand HGF induces MET kinase catalytic activity, which triggers transphosphorylation of the tyrosines Tyr 1234 and Tyr 1235. These two tyrosines engage various signal transducers, thus initiating a whole spectrum of biological activities driven by MET, collectively known as the invasive growth program. The transducers interact with the intracellular multisubstrate docking site of MET either directly, such as GRB2, SHC, SRC, and the p85 regulatory subunit of phosphatidylinositol-3 kinase (PI3K), or indirectly through the scaffolding protein Gab1
Tyr 1349 and Tyr 1356 of the multisubstrate docking site are both involved in the interaction with GAB1, SRC, and SHC, while only Tyr 1356 is involved in the recruitment of GRB2, phospholipase C γ (PLC-γ), p85, and SHP2.
GAB1 is a key coordinator of the cellular responses to MET and binds the MET intracellular region with high avidity, but low affinity. Upon interaction with MET, GAB1 becomes phosphorylated on several tyrosine residues which, in turn, recruit a number of signalling effectors, including PI3K, SHP2, and PLC-γ. GAB1 phosphorylation by MET results in a sustained signal that mediates most of the downstream signaling pathways.
Activation of signal transduction
MET engagement activates multiple signal transduction pathways:
- The RAS pathway mediates HGF-induced scattering and proliferation signals, which lead to branching morphogenesis. Of note, HGF, differently from most mitogens, induces sustained RAS activation, and thus prolonged MAPK activity.
- The PI3K pathway is activated in two ways: PI3K can be either downstream of RAS, or it can be recruited directly through the multifunctional docking site. Activation of the PI3K pathway is currently associated with cell motility through remodeling of adhesion to the extracellular matrix as well as localized recruitment of transducers involved in cytoskeletal reorganization, such as RAC1 and PAK. PI3K activation also triggers a survival signal due to activation of the AKT pathway.
- The STAT pathway, together with the sustained MAPK activation, is necessary for the HGF-induced branching morphogenesis. MET activates the STAT3 transcription factor directly, through an SH2 domain.
- The beta-catenin pathway, a key component of the Wnt signaling pathway, translocates into the nucleus following MET activation and participates in transcriptional regulation of numerous genes.
Role in development
During embryonic development, transformation of the flat, two-layer germinal disc into a three-dimensional body depends on transition of some cells from an epithelial phenotype to spindle-shaped cells with motile behaviour, a mesenchymal phenotype. This process is referred to as epithelial-mesenchymal transition (EMT). Later in embryonic development, MET is crucial for gastrulation, angiogenesis, myoblast migration, bone remodeling, and nerve sprouting among others. MET is essential for embryogenesis, because MET -/- mice die in utero due to severe defects in placental development. Furthermore, MET is required for such critical processes as liver regeneration and wound healing during adulthood.
Tissue distribution
MET is normally expressed by epithelial cells. However, MET is also found on endothelial cells, neurons, hepatocytes, hematopoietic cells, and melanocytes. HGF expression is restricted to cells of mesenchymal origin.
Transcriptional control
MET transcription is activated by HGF and several growth factors. MET promoter has four putative binding sites for Ets, a family of transcription factors that control several invasive growth genes. ETS1 activates MET transcription in vitro. MET transcription is activated by hypoxia-inducible factor 1 (HIF1), which is activated by low concentration of intracellular oxygen. HIF1 can bind to one of the several hypoxia response elements (HREs) in the MET promoter. Hypoxia also activates transcription factor AP-1, which is involved in MET transcription.
Role in cancer
MET pathway plays an important role in the development of cancer through:
- angiogenesis (sprouting of new blood vessels from pre-existing ones to supply a tumor with nutrients);
- scatter (cells dissociation due to metalloprotease production), which often leads to metastasis.
Coordinated down-regulation of both MET and its downstream effector extracellular signal-regulated kinase 2 (ERK2) by miR-199a* may be effective in inhibiting not only cell proliferation but also motility and invasive capabilities of tumor cells.
Interaction with tumour suppressor genes
PTEN (phosphatase and tensin homolog) is a tumor suppressor gene encoding a protein PTEN, which possesses lipid and protein phosphatase-dependent as well as phosphatase-independent activities. PTEN protein phosphatase is able to interfere with MET signaling by dephosphorylating either PIP3 generated by PI3K, or the p52 isoform of SHC. SHC dephosphorylation inhibits recruitment of the GRB2 adapter to activated MET.
Cancer therapies targeting HGF/MET
Since tumor invasion and metastasis are the main cause of death in cancer patients, interfering with MET signaling appears to be a promising therapeutic approach. A comprehensive list of HGF and MET targeted experimental therapeutics for oncology now in human clinical trials can be found here.
MET kinase inhibitors
Kinase inhibitors are low molecular weight molecules that prevent ATP binding to MET, thus inhibiting receptor transphosphorylation and recruitment of the downstream effectors. The limitations of kinase inhibitors include the facts that they only inhibit kinase-dependent MET activation, and that none of them is fully specific for MET.
- K252a (Fermentek Biotechnology) is a staurosporine analogue isolated from Nocardiopsis sp. soil fungi, and it is a potent inhibitor of all receptor tyrosine kinases (RTKs). At nanomolar concentrations, K252a inhibits both the wild type and the mutant (M1268T) MET function.
- SU11274 (SUGEN) specifically inhibits MET kinase activity and its subsequent signaling. SU11274 is also an effective inhibitor of the M1268T and H1112Y MET mutants, but not the L1213V and Y1248H mutants. SU11274 has been demonstrated to inhibit HGF-induced motility and invasion of epithelial and carcinoma cells.
- PHA-665752 (Pfizer) specifically inhibits MET kinase activity, and it has been demonstrated to represses both HGF-dependent and constitutive MET phosphorylation. Furthermore, some tumors harboring MET amplifications are highly sensitive to treatment with PHA-665752.
- ARQ197 (ArQule) is a promising selective inhibitor of MET, which entered a phase 2 clinical trial in 2008.
- Foretinib (XL880, Exelixis) targets multiple receptor tyrosine kinases (RTKs) with growth-promoting and angiogenic properties. The primary targets of foretinib are MET, VEGFR2, and KDR. Foretinib has completed a phase 2 clinical trials with indications for papillary renal cell carcinoma, gastric cancer, and head and neck cancer.
- SGX523 (SGX Pharmaceuticals) specifically inhibits MET at low nanomolar concentrations.
- MP470 (SuperGen) is a novel inhibitor of c-KIT, MET, PDGFR, Flt3, and AXL. Phase I clinical trial of MP470 had been announced in 2007.
HGF inhibitors
Since HGF is the only known ligand of MET, formation of a HGF:MET complex blocks MET biological activity. For this purpose, truncated HGF, anti-HGF neutralizing antibodies, and an uncleavable form of HGF have been utilized so far. The major limitation of HGF inhibitors is that they block only HGF-dependent MET activation.
- NK4 competes with HGF as it binds MET without inducing receptor activation, thus behaving as a full antagonist. NK4 is a molecule bearing the N-terminal hairpin and the four kringle domains of HGF. Moreover, NK4 is structurally similar to angiostatins, which is why it possesses anti-angiogenic activity.
- Neutralizing anti-HGF antibodies were initially tested in combination, and it was shown that at least three antibodies, acting on different HGF epitopes, are necessary to prevent MET tyrosine kinase activation. More recently, it has been demonstrated that fully human monoclonal antibodies can individually bind and neutralize human HGF, leading to regression of tumors in mouse models. Two anti-HGF antibodies are currently available: the humanized AV299 (AVEO), and the fully human AMG102 (Amgen).
- Uncleavable HGF is an engineered form of pro-HGF carrying a single amino-acid substitution, which prevents the maturation of the molecule. Uncleavable HGF is capable of blocking MET-induced biological responses by binding MET with high affinity and displacing mature HGF. Moreover, uncleavable HGF competes with the wild-type endogenous pro-HGF for the catalytic domain of proteases that cleave HGF precursors. Local and systemic expression of uncleavable HGF inhibits tumor growth and, more importantly, prevents metastasis.
Decoy MET
Decoy MET refers to a soluble truncated MET receptor. Decoys are able to inhibit MET activation mediated by both HGF-dependent and independent mechanisms, as decoys prevent both the ligand binding and the MET receptor homodimerization. CGEN241 (Compugen) is a decoy MET that is highly efficient in inhibiting tumor growth and preventing metastasis in animal models.
Immunotherapy targeting MET
Drugs used for immunotherapy can act either passively by enhancing the immunologic response to MET-expressing tumor cells, or actively by stimulating immune cells and altering differentiation/growth of tumor cells.
Passive immunotherapy
Administering monoclonal antibodies (mAbs) is a form of passive immunotherapy. MAbs facilitate destruction of tumor cells by complement-dependent cytotoxicity (CDC) and cell-mediated cytotoxicity (ADCC). In CDC, mAbs bind to specific antigen, leading to activation of the complement cascade, which in turn leads to formation of pores in tumor cells. In ADCC, the Fab domain of a mAb binds to a tumor antigen, and Fc domain binds to Fc receptors present on effector cells (phagocytes and NK cells), thus forming a bridge between an effector and a target cells. This induces the effector cell activation, leading to phagocytosis of the tumor cell by neutrophils and macrophages. Furthermore, NK cells release cytotoxic molecules, which lyse tumor cells.
- DN30 is monoclonal anti-MET antibody that recognizes the extracellular portion of MET. DN30 induces both shedding of the MET ectodomain as well as cleavage of the intracellular domain, which is successively degraded by proteasome machinery. As a consequence, on one side MET is inactivated, and on the other side the shed portion of extracellular MET hampers activation of other MET receptors, acting as a decoy. DN30 inhibits tumour growth and prevents metastasis in animal models.
- OA-5D5 is one-armed monoclonal anti-MET antibody that was demonstrated to inhibit orthotopic pancreatic and glioblastoma tumor growth and to improve survival in tumor xenograft models. OA-5D5 is produced as a recombinant protein in Escherichia coli. It is composed of murine variable domains for the heavy and light chains with human IgG1 constant domains. The antibody blocks HGF binding to MET in a competitive fashion.
Active immunotherapy
Active immunotherapy to MET-expressing tumors can be achieved by administering cytokines, such as interferons (IFNs) and interleukins (IL-2), which triggers non-specific stimulation of numerous immune cells. IFNs have been tested as therapies for many types of cancers and have demonstrated therapeutic benefits. IL-2 has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of renal cell carcinoma and metastatic melanoma, which often have deregulated MET activity.

A transportation study by engineering researchers reveals that different speed limits for cars and large trucks on rural, interstate highways can compromise safety.
“We found that speed variation and vehicle interactions have a direct impact on highway safety,” said Steven Johnson, professor of industrial engineering with the Mack Blackwell Transportation Center. “Data from previous studies and simple logic say that a higher number of interactions among vehicles increases the chances that accidents will occur.”
Johnson reported this finding in Cost-Benefit Evaluation of Heavy Truck-Automobile Speed Differentials on Rural Interstate Highways, a study of speed limits and car-versus-large-truck speed differentials on rural, interstate highways. Sponsored by the U.S. Department of Transportation, commercial trucking companies and private fleets, the study will help regulatory agencies and trucking-company decision-makers establish policies regarding speed limits and differentials for both heavy trucks and automobiles.
After examining existing literature on speed limits, Johnson and graduate student Naveen Pawar measured the speeds of heavy trucks and automobiles in five states. Speed-limit configurations ranged from a uniform 75 mph for cars and heavy trucks to 65 mph for automobiles and 55 mph for trucks. The researchers also analyzed speed, accident and maintenance data and interviewed truck drivers, safety and maintenance managers of commercial trucking companies and original equipment manufacturers of trucks, tires and engines.
There is a caveat to their findings: vehicle dynamics, such as braking and maneuvering, improve on slower-moving trucks.
“People argue that heavy trucks require longer braking distances for any given speed, and lower truck speeds help equalize the stopping distance,” Johnson said. “On the other hand, opponents of lower truck speed limits have suggested that the differential speeds increase speed variance and therefore have a negative impact on highway safety. Our research demonstrates that it is likely that both of these arguments are correct.”

Aleutian lowArticle Free Pass
Aleutian low, large atmospheric low-pressure (cyclonic) centre that frequently exists over the Aleutian Islands region in winter and that shifts northward and almost disappears in summer. Although the Aleutian low is associated with smaller eastward-moving low- and high-pressure centres, the region’s average pressure is low. It is the source region of the maritime polar air masses that influence the climate of the western U.S. The low-pressure centres that persist in the higher latitudes of the Northern Hemisphere consist of the Aleutian low and the Icelandic low.

Mersen, Treaty of
Mersen, Treaty of, 870, redivision of the Carolingian empire by the sons of Louis I, Charles the Bald (later Charles II) of the West Franks (France) and Louis the German of the East Franks (Germany), signed at Mersen (Dutch Meersen ), now in the Netherlands. The treaty superseded the tripartite division of the empire in 843 (see Verdun, Treaty of). It divided the kingdom of Lotharingia between Charles and Louis, following the death (869) of their nephew, Lothair, king of Lotharingia. France obtained the territories roughly corresponding to the modern Netherlands, Belgium, and Lorraine and Germany received Alsace and the left bank of the Lower Rhine. The borders established did not last long.

05/10/2012 - Americans love economic mobility. It’s kind of a founding myth for us: We see ourselves as having broken free from rigid, aristocratic Europe to form a meritocracy that guaranteed a chance to move up in the world. Though there has been much talk lately about rising income inequality in the United States, what has worried pundits on both the left and the right has been recent reports that Americans aren’t as economically mobile as citizens in other Western nations.
The Pew Economic Mobility Project has been studying this phenomenon, and is out with a new report examining which regions in America are the most and least mobile. Researchers looked at Americans ages 35 to 39 and then examined their incomes ten years later. The study covered the time period between 1978 and 2007, and tackled three different measures of income mobility: absolute mobility (as measured by inflation-adjusted income growth over time), and relative upward and downward mobility — i.e. movement up or down the socio-economic ladder. In other words, are Americans born poor becoming rich and vice-versa?
Interestingly enough, geographic mobility doesn’t appear have a large effect on economic mobility. That is, it doesn’t matter if you’re born in Maryland or you move there – you’re more likely move up the economic ladder either way. According to Erin Currier, Project Manager of the Pew Economic Mobility Project, individuals who do move states do have better economic mobility, but more than two-thirds of Americans stay in their birth state for the remainder of their lives. Therefore, “Geographic mobility might help an individuals’ economic mobility, [but] it’s not really driving state-level findings as a whole.”
So why are some states more economically mobile than others? This study doesn’t seek to specifically address the causes of relative mobility between states, but there are some important factors that the Economic Mobility Project has found are essential to promoting economic mobility overall, and these include things like like “educational attainment, savings and asset building, and neighborhood poverty during childhood,” according to Currier.

Subfertility, a condition in which a person is less fertile than average but still capable of contributing to a pregnency, affects about one in 20 men. Up to 80 percent of subfertility could be due to sperm damage caused by oxidative stress or harmful particles produced by a person's own body.
While infertility has historically been seen as a woman's problem, male infertility is present in up to half of infertile couples.
Varicocele, a condition in which a man has varicose veins in the scrotum, is the most common cause of male subfertility. Other causes include hormonal disorders, problems with quantity and motility of sperm, infections, obesity, drug use and exposure to radiation and chemotherapy. Depending on the condition, male infertility and subfertility can be treated with surgery, hormone therapy and assisted reproductive technologies.
While, as we've seen, some doctors dismissed the link between antioxidants and fertility, others said they were not surprised by the results because healthy nutrition and lifestyle are already recommended for couples planning to conceive.
Dr. Jeanne O'Brien, associate professor of urology at University of Rochester Medical Center, is one of those doctors. O'Brien said she routinely suggests that her patients take antioxidants if they want a baby. She also recommends decreasing alcohol consumption, smoking cessation, exercising and stress reduction.
"I tell them the antioxidants may help and certainly don't harm them at the recommended dosages," said O'Brien. "I believe it is the lifestyle changes and increased health awareness that accompanies antioxidant consumption that may make a difference in terms of increased fertility."
O'Brien said antioxidants are never her sole recommendations. "There are always additional factors, testing, medication or alternatives offered in conjunction with them," O'Brien said.
"I use antioxidants for select men with impaired semen quality and demonstration of elevated oxidative stress, which is manifest by increased levels of reactive oxygen species," said Kim. "However, I do not assess for oxidative stress if identifiable causes of male infertility are present. In clinical practice, improvements in pregnancy and live birth rates are certainly not as robust as suggested by the Cochrane review."
And Kim warns that, despite the hype around antioxidant supplements, they should not be consumed without a watchful eye. For example, excessive consumption of Vitamin E, or more than 400 units per day, has been shown to have possible negative cardiac and vascular effects.
"Although generally considered safe in moderation, numerous large-scale studies have indicated that many supplemental antioxidants can actually be detrimental to overall health, said Kim. "With an understanding of these caveats, an assessment of the severity of male factor infertility, and very modest expectations of possible benefit, a man could try antioxidants before attempting assisted reproduction." | <urn:uuid:5d1227e2-2f7f-4ad7-b06a-0d8d6d08f4da> | http://abcnews.go.com/Health/antioxidants-increase-male-fertility/story?id=12641649&page=2 |

In the summer of 2007, shoppers at some food co-ops in the upper Midwest encountered a new label on their produce: “Local Fair Trade.” Seasonal staples such as cucumbers, squash, and broccoli were the first to don the label, a large, hard-to-miss sticker symbolizing the union of two approaches to sustainable food: eating food grown locally, and purchasing food traded fairly.
We’ve gotten used to a variety of labels on our food. There’s “organic,” which used to connote ideas like “pure” and “natural” but these days technically means food certified as organic by the USDA (if domestically produced) or by the food’s country of origin. “Local” usually means food grown or produced within a few hundred miles of its selling location. And “fair trade” is seen most commonly on popular imports such as coffee and chocolate; the label means that the food’s growers or producers were paid a decent wage.
So what does “local fair trade” mean? According to Erik Esse, the director of the Minneapolis-based Local Fair Trade Network, the label is an attempt to answer a question: “How can the principles of fair trade, which have effectively moved many farmers and workers in the developing world out of poverty and towards self-sufficiency, work here in the U.S., where our farmworkers are having some of the same problems?”
At the heart of the local or “domestic fair trade” label is the idea of fair and equitable relationships. The label can be applied to food grown in the U.S. under a set of guidelines, including a living wage and an emphasis on fair and healthy living conditions. The product of nearly a decade of careful planning, the domestic fair-trade label is an effort to incorporate social-justice awareness into our burgeoning efforts to eat foods that have been cleanly and sustainably produced.
As the fair-trade movement (both international and domestic) wants everyone to understand, the local people behind the food we eat deserve sustainability, too. The USDA’s national organic standards guarantee that organically certified food is not genetically modified and is grown without petroleum-based fertilizers or synthetic chemicals. But the standards have nothing to say about the people who produce the food. This fact appalls those who work closely with farmworkers, including Richard Mandelbaum of El Comité de Apoyo a los Trabajadores Agrícolas (CATA), a migrant-farmworker organization based in New Jersey.
“Organic standards include all sorts of rules about how livestock needs to be treated, but absolutely none for the human beings that are on the farm,” says Mandelbaum.
The Local Fair Trade Network’s Esse isn’t sure that enough consumers are paying attention to those human beings, either. “The way stores like to put up pictures of happy farmers these days — that’s in some ways great, in that it’s identifying that there’s a person growing their food,” he says. “But in some ways, those smiles mask the fact of how little money they get paid and how hard their lives are.”
Although some organic farms in the U.S. opt to pay their workers a living wage, as well as provide vacation days and access to health care, many do none of those things. Small-scale organic farmers, who often live hand-to-mouth themselves, rarely have the budget to do so. And most large, industrial-sized organic farms rely on hundreds if not thousands of underpaid migrant workers, in much the same way that conventional farms and food processors do.
According to a 2005 survey report from the University of California, Davis, the majority of the 188 California organic farms surveyed did not pay a living wage or provide medical or retirement plans. And despite the nationwide boom in organic food — the industry was worth more than $17 billion by the end of 2006 — the wealth has not trickled down. While the absence of synthetic pesticides (and the health impacts that accompany them) can be a draw to some workers, most employees on organic farms earn no more than those on conventional ones.
Across the country, three to five million people labor every year on farms and in factories, planting, cultivating, harvesting, and processing fresh produce and other agricultural products. Their lives are anything but easy. According to the National Agricultural Workers Survey, 61 percent of farmworkers live in poverty. In recent years, their median income has not kept up with inflation: for individual farmworkers, the median annual income is now $7,500, while for farmworker households, the median annual income is less than $10,000. (The overall U.S. median household income, according to the U.S. Census Bureau, is more than $48,000.) It is also estimated that between 72 and 78 percent of farmworker households have no health insurance.
Today’s domestic fair-trade movement dates back as far as 1999, when CATA, along with Rural Advancement Foundation International-USA (RAFI-USA) and several other partners, argued for an inclusion of labor issues in the federal organic standards.
“When it became clear that the issues of social justice and fairness would not be incorporated into the federal [organic standards],” says RAFI’s Michael Sligh, “that really triggered our work to look at opportunities to make that additional claim to the marketplace.”
The result was something called the Agricultural Justice Project (AJP), a group that set to work devising a separate set of standards that would cover both equity for the small-scale farmer as well as fair working conditions for farmworker. But not everyone was convinced.
“When we first started out, it wasn’t uncommon to get a shrug from those in the organic/sustainable community, with responses like, ‘I’m not sure why you’re focused on this,’” says CATA’s Mandelbaum. “But in the last two years, we’ve seen that consumers are increasingly dissatisfied with anonymous products, and really want to know how their food is made — environmentally of course, but also increasingly socially.”
In 2005, the Agricultural Justice Project, along with the international fair-trade organization Equal Exchange and several domestic farmer cooperatives, held the first meeting of the Domestic Fair Trade Working Group (now renamed the Domestic Fair Trade Association). By 2006, it became clear that the best place to pilot a domestic fair-trade label was the Minnesota/Wisconsin area.
According to Erik Esse, whose Local Fair Trade Network is the Minneapolis-based arm of the movement, there are around 40 food co-ops in Minnesota and more than 25 in Wisconsin. “The fact that consumer cooperatives are so key to the area,” he says, “as opposed to the corporate natural-food-store model, means we have a background that lends to embracing fair trade. [The customers] already believe in democracy and in consumer activism.”
By early 2007, four small farms in the upper Midwest had been chosen to participate in the Domestic Fair Trade Working Group’s pilot project, along with two food co-ops in the Minneapolis area. All the farms involved were closely audited, including their business practices and employee policies. And they pledged to, among other things, “1) Respect workers’ freedom of association and right to collective bargaining, 2) Provide adequate health and safety protections, including access to adequate medical care, information on potential hazards, and using the least toxic methods available, and 3) Pay a living wage.”
Esse points out that although small-scale farmers and farmworkers are often in similar financial situations, there is still some tension between the two groups. “Farmers don’t always want to stir the pot,” he says. “We often hear, ‘Things are going fine; why would I want to bring this up?’”
Rufus Hauke, of Keewaydin Farms in Viola, Wisconsin, does want to stir the pot. He’s a produce farmer participating in the pilot project who, along with his brother, decided to remake the family farm according to a vision for what he calls “the next evolution of food.” Although he has only a few employees, Hauke was excited to offer them the paperwork and training necessary to help get the first Keewaydin Fair Trade growing season off the ground.

Numerous studies, including one released last month by University of Louisville researchers, indicate that learning to play the piano as a preschooler sets a child up for later academic success. And now "Piano For Preschoolers" has introduced a new way for parents to teach their children the piano - complete with a Casio(R) keyboard.
Developed by Angie Crellin, a mother of two who has studied the piano for over 30 years, "Piano For Preschoolers" uses color-coded notes printed on a traditional musical staff to teach songs preschoolers already love, like "Twinkle, Twinkle, Little Star." A corresponding color strip sits behind the piano's keys and guides the child to the correct key for each note.
Crellin came up with the "Piano For Preschoolers" concept when her son, a preschooler at the time, expressed interest in playing the piano. Crellin's daughter had done the same several years before, but she had quickly lost interest once Crellin introduced popular beginning piano books to the lessons. Not wanting the same thing to happen with her son, Crellin decided to create a program that was fun for children and easy for parents to teach. Hundreds of hours of research later, she had "Piano For Preschoolers."
"The results were amazing," said Crellin. "My son loved playing real songs he recognized and couldn't wait to learn more. But the truly remarkable thing was that my preschool son started helping my second-grade daughter with her math homework."
Crellin's results correspond to those obtained by Dr. Frances Rauscher of the University of Wisconsin and Dr. Gordon Shaw of the University of California. The researchers, who have long studied the connection between math and music, compared the effects of musical and nonmusical training on preschoolers' intellectual development. They found that preschoolers who received piano or keyboard training performed 34% higher on tests measuring spatial-temporal ability than did other preschoolers. Those who received piano or keyboard training could think in pictures and see the pictures moving or changing shape over time - a crucial skill for later success in mathematics, science and engineering.
But the pint-sized students of "Piano For Preschoolers" don't care about all that. Most are just having fun playing for rapt audiences of parents and grandparents.
"The 'Piano For Preschoolers' program really seems to be boosting children's self-confidence," said Crellin. "Customers report their preschoolers are practicing the piano with no prompting from the parents. And that's really the key. No four-year-old will stay motivated to learn if she isn't having fun."
The entire "Piano For Preschoolers" system is $129.95 plus shipping. It includes: a music book of 17 familiar songs written in color-coded notes; the durable color strip to set behind the piano keys; a parent/teacher guide with step-by-step instructions for each lesson; and a free Casio(R) SA-75 electronic keyboard.

Big Leap Forward in Understanding Genetics Underlying Prevalent Diseases
The Wellcome Trust Case Control Consortium (WTCCC), a collaboration of 24 leading human geneticists analyzing thousands of DNA samples from patients suffering prevalent human diseases, have announced breakthrough research findings. Hailed as a "...new chapter in medical science...", genetic variants have been found for:
- Crohn's disease
- coronary heart disease
- rheumatoid arthritis
- Type I and Type II diabetes
Some of the fascinating findings:
- Type I Diabetes and Crohn's disease share a common gene, suggesting similar biological pathways!
- An obesity gene as well as three new genes linked to Type II Diabetes
- The WTCCC used gene chip technology, which is not unlike microchip technology, enabling scientists to scan hundreds of thousands of DNA markers at once.

A view can become a page or a block. There is no difference in work between a page and a block. A page needs a path to display the page. A block is assigned to a region to display the page. There might be a few seconds different to set them up. After that, you can blocks in far more ways than usually shown in tutorials.
Blocks have their uses including constructing complex pages. The content of a page is usually the content of a node in the content region. A view replaces the node to display a list or some other small variation of content.
Next you are asked to make the view more complicated. You scratch your head. What you really need is a collection of views displaying different content. You could use panels and a bunch of other complex approaches. Think about the format again.
If you want a list of different views. You can make each one a block then place them one after the other down the page. Consider a shop.
A shop might list the top selling product in each category with a view sorted by category. The marketing manager then asks for the categories in a different order. The CEO wants some categories to list the top three. The product manager wants one category to list only one product but all the colours for the product.
You could make each category a separate view with each view in a block. Each view can have different criteria. You can give your CEO, sales manager, and marketing manager access to the block admin page and let them fight over the sequence of the blocks.
What method do you use to determine when to use multiple views?
Use the one view when you list data one set of data. Use multiple views when people want different data selection. For example, some product categories have colours but not all product categories. Some product categories have multiple packs but not all product categories.
If the one list has to be by category then colour or pack size and all the products use the same content type, you could use one view to sort by category then colour then pack size. There will be no overlap or conflict or missing data.
The same list becomes more complicated when each product category has a different content type and each content type has a different set of attributes. You might be able to product one list in one view but it will be sensitive to change and management will want change. Start with two views or more views stacked as blocks to form one list.
Another example is a book shop where novels have different descriptions and content types compared to other books. Cook books may have a special content type to allow listing by food type, country, major ingredients, and the reality television show paying for the cook book.
If the data is exactly the same for each view but the display is different, consider multiple displays on one view. The technique is described in another page. you make the first view a page to list the data and validate your data selection. You then add some displays to create the blocks. Each display might vary by as little as selecting a different content type.
Top ten lists are popular and soon take up too much space. People start talking about variations. Perhaps the top three items, including teasers, followed by the next seven without teasers. | <urn:uuid:b833e175-0f06-496c-90a2-fc2151545197> | http://www.petermoulding.com/views_development_-_page_or_block |
As a developmental pathway towards autonomy and dexterity in robot in-hand manipulation, HANDLE is a Large Scale IP project coordinated by the university Pierre and Marie Curie of Paris and include a consortium formed by nine partners from six EU countries: France, UK, Spain, Portugal, Sweden, and Germany.
The TACO project aims at enhancing the abilities of service robots by improving the sensing system with real 3D foveation properties and to increase their ability to interact with their natural environment in a more natural and human-like way.
The PV-Servitor project focuses on concepts for a fully autonomous cleaning robot for ground mounted large scale photovoltaic power plants consisting of 100 kW and over.
STIFF-FLOP is researching how to take some of the new capabilities in soft robotics and apply them to the development of tools for endoscopic surgery. This project takes inspiration from octopus tentacles for the design of flexible soft robots.
DEXDEB is researching meat deboning. Taking apart an animal carcass to produce high-quality pieces of meat is a skilled but unpleasant and dangerous task. In DEXDEB we are looking at two designs of robotic hand and using them as the “left hand” that pulls at the meat, while a human operator slices the meat with a knife held in their right hand. This will provide DEXDEB with a baseline for doing more complex human-robot interaction work later.
HYFLAM is investigating the role of robotics in biosafety level 3 and 4 laboratories. Working with a UK Government lab and Hamburg University, HYFLAM is looking at a range of skilled tasks and investigating whether a robotic hand can perform them, and how well it performs them when working with software like that developed in HANDLE. This could lead to a new generation of robotic systems for hazardous lab work. | <urn:uuid:f74a9ce3-5706-4b3e-81a8-1da2cec57638> | http://www.shadowrobot.com/consulting/research-activity/ |
Is it scientific fact that acid stabilizes meringue or is this a fallacy? If so does anyone know actually why and are there any other substances that do this well also?
Acids allow more air to be beaten into a meringue. In order to make meringue, the proteins in egg white must be denatured. In their natural state, the proteins are curled up into tightly packed balls. When the egg is beaten, they uncoil into long strands.
These strands then begin to coagulate, or join together, with the help of the sugar you add. The air you whisk in gets trapped between these joining strands, giving the meringue its characteristic light texture.
Acid delays coagulation, which means that there is more time for air to get trapped in amongst the proteins, resulting in a lighter meringue.
The acids usually added to meringue are white wine vinegar, lemon juice, or cream of tartar. Fresh eggs are more acidic than old ones, so these help too.
Some cooks use copper bowls to make meringue, because copper ions from the bowl bind to a particular protein (conalbumin) and strengthen it.

I have made two separate meringue mixtures side by side: one with vinegar and one without. In my experience it makes no difference to the final outcome provided that you add the sugar really slowly (a tablespoon at a time) and not too early. If this is done correctly then there is no need to add an acid. | <urn:uuid:f800d702-9456-46be-9fab-b3ceed8033d0> | http://cooking.stackexchange.com/questions/23935/does-an-acid-actually-stabilize-meringue-and-if-so-why |
International Women’s Day (IWD) was founded in 1910 in order to confront the great inequalities women faced in the labor force and society as a whole. Unfortunately, one hundred years later, women still make up a majority of the world’s poor.
Women’s wages in the U.S. are only 76% of men’s, but the disparity of long-term earnings between men and women is far worse. A study comparing total earnings between 1983 and 1998 showed women averaging just 38% of men’s wages (Institute for Women’s Policy Research, 2004).
In large part, this is because 80% of American women under 40 are mothers, according to the U.S. census. Without adequate paid maternity leave, mothers are frequently forced to quit stable jobs and disrupt career plans. Add to that $611 in average monthly childcare costs (U.S. Department of Labor), which is more than two weeks pay at the federal minimum wage.
Eighty-seven percent of single parent households are headed by women and of those 37% are in poverty (Association for Women’s Rights and Development). Once a family falls into poverty it is astoundingly hard for them to escape. Sixty percent of families that are in the bottom fifth of income remain there a decade later (Association for Women’s Rights and Development).
The impact of the financial crisis, however, is worldwide. Of the 1.5 million people living on a dollar or less per day, 70% are women (UN.org). Forced into the factories with the worst working conditions, women make up 90% of the world’s sweatshop labor (Women Thrive Worldwide). Often being laid off, these women are accustomed to making 13 cents to one dollar per hour (Powell and Skarbek 2004). Forced to work, women are less likely to attend school or leave the home before marriage. Seventy-seven million girls of primary school age worldwide are out of school, compared to only 55 million boys (The World Bank).
Women around the world are bound together by discrimination and economic servitude created by capitalism. Their work is devalued down to pennies, and often the largest use of their time - household labor - goes unpaid. IWD is a chance to remember and celebrate the struggles of women, which have won huge improvements in our lives. If women united internationally and with the wider struggles of working people to fight for equal rights, better working conditions, wages and stronger social services such as health care, child care and food support, we could collectively improve conditions for all. | <urn:uuid:0681e861-7b72-460f-8ca5-d3e891c9a360> | http://socialistalternative.org/news/article16.php?id=1277 |
Chile's economy is based on the export of minerals, which account for about half of the total value of exports. Copper is the nation's most valuable resource, and Chile is the world's largest producer. Agriculture is the main occupation of about 15% of the population; it accounts for about 6% of the national wealth, and produces less than half of the domestic needs. The Vale of Chile is the country's primary agricultural area; its vineyards are the basis of Chile's wine industry. Grapes, apples, pears, onions, wheat, corn, oats, peaches, garlic, asparagus, and beans are the chief crops. Livestock production includes beef and poultry. Sheep raising is the chief pastoral occupation, providing wool and meat for domestic use and for export. Fishing and lumbering are also important economic activities. Chile's industries largely process its raw materials and manufacture various consumer goods. The major products are copper and other minerals, processed food, fish meal, iron and steel, wood and wood products, transportation equipment, and textiles.
The dependence of the economy on copper prices and the production of an adequate food supply are two of Chile's major economic problems. Chile's main imports are petroleum and petroleum products, chemicals, electrical and telecommunications equipment, industrial machinery, vehicles, and natural gas. In addition to minerals, it also exports fruit, fish and fish products, paper and pulp, chemicals, and wine. The chief trading partners are the United States, China, Brazil, Argentina, and South Korea.

When Striving for Perfection Is a Problem
Last Reviewed by Faculty of Harvard Medical School on May 4, 2012
By Howard LeWine, M.D.
Harvard Medical School
Some people can't live with the slightest imperfection. Their need to appear or be perfect perfectionism is so intense that it's exhausting if not painful.
But striving for perfection, while accepting that perfection rarely can be achieved, can lead to growth and development and a feeling of satisfaction. It can be a powerful motivator as long as it is based on reasonable standards and expectation. For example, the desire to have a perfect golf swing or tennis stroke can enhance the pleasure you take in these pursuits, whether you are an amateur or professional.
Perfectionism is unproductive, however, when it is linked to excessively high standards and is driven by a fear of failure.

Types of Perfectionism
Perfectionism comes in many forms:
- Obsessive concern over mistakes
- Setting excessively high personal standards
- Perceiving parents as overly critical
- Unreasonable doubts about ability to perform tasks
- An over-emphasis on organization
- Trying to live up to high expectations you're convinced other people, such as parents, have of you
- Having high expectations of other people
But whatever form it takes, perfectionism can rob you of life's pleasures.

The Roots of Perfectionism
It may not be so easy to figure out where perfectionism comes from. For some, it is a part of their inborn temperament like perfect skin and teeth. Researchers have linked perfectionism to anxiety, depression and eating disorders. The trait of perfectionism is common among people with obsessive-compulsive disorders. Or it could be a response to having parents who expected too much from you. Maybe they never let you off the hook, even if you got 98 out of 100 on an exam.

The Role of Indirect Aggression
What goes on outside the home is also a big factor in the development of perfectionism. For some women, perfectionism is a way to cope with indirect aggression, a term for the socially manipulative behaviors of the stereotypical "mean girls" that they may have experienced.
A recent study published in the journal Aggressive Behavior supports the idea that perfectionism may develop in a social group and suggests that indirect aggression triggers it. The "aggressor" talks behind a person's back, gives someone the "silent treatment," tells secrets, or is nice in private but rejecting in public to hide her hostility toward another.
Girls and women tend to resort to this kind of social bullying because they are not encouraged or taught how to express aggressive or competitive feelings directly. They become aggressive in ways that can be easily concealed or denied.
For the study, researchers at McMaster University asked two groups of college-age women to fill out surveys about what types of verbal abuse, physical abuse and indirect aggression they had experienced in grades 3 through 12. They also asked the women to answer questions to gauge whether they were perfectionists.
The women who recalled experiencing indirect aggression in childhood were more likely to become perfectionists by the time they reached college. Verbal and physical abuse apparently was not linked to perfectionism.
The authors acknowledge that the study asked subjects to report on old experiences and that women who are perfectionistic might be more likely to recall past events in a negative way, no matter how they were treated in reality.
Even so, the authors say that a victim of indirect aggression may without knowing it come to feel that being "perfect" is the only way to assert herself in social situations or maintain control. Thus, perfectionism becomes a way to cope with a threatening environment.

Making Perfectionism Work for You
There is a fine line between the positive aspects of striving to be perfect and perfectionism that can be detrimental. Striving to be perfect can be very positive as long as it:
- Is realistic
- Moves you forward
- Helps you feel stronger
- Gives you the satisfaction you deserve after all that hard work.
Perfectionism becomes a problem when it makes you feel worse instead of better, or when your inability to be satisfied unless you are perfect realizing that it will always be out of reach causes suffering.
You can make perfectionism work for you. Here's how:
- Look at and change unrealistic and self-destructive thought patterns with cognitive behavior therapy.
- Understand how you became perfectionistic and ease up on unwarranted self-criticism. Psychodynamic therapy can help you do this.
- If you do have one of the underlying disorders linked to perfectionism (obsessive-compulsive disorder, anxiety or depression), then a medication or psychotherapy may help by targeting the pressure coming from that source.
Consult a mental health professional as a first step. The goal is to let go of the excessively high standards and find ways to cope with fears of failure. At the same time, you want to hold on to the positive force of striving for perfection.

BSID-III is the current version and is a standard series of measurements used primarily to assess the motor (fine and gross), language (receptive and expressive), and cognitive development of infants and toddlers, ages 0-3. This measure consists of a series of developmental play tasks and takes between 45 - 60 minutes to administer. Raw scores of successfully completed items are converted to scale scores and to composite scores. These scores are used to determine the child's performance compared with norms taken from typically developing children of their age (in months). The assessment is often used in conjunction with the Social-Emotional Adaptive Behavior Questionnaire. Completed by the parent or caregiver, this questionniare establishes the range of adaptive behaviors that the child can currently achieve and enables comparison with age norms.

Scripture always speaks with absolute authority. It is as authoritative when it instructs us as it is when it commands us. It is as true when it tells the future as it is when it records the past. Although it is not a textbook on science, wherever it intersects with scientific data, it speaks with the same authority as when it gives us moral precepts. Although many have tried to set science against Scripture, science never has disproved one jot or tittle of the Bible--and it never will.
It is therefore a serious mistake to imagine that modern scientists can speak more authoritatively than Scripture on the subject of origins. Scripture is God's own eyewitness account of what happened in the beginning. When it deals with the origin of the universe, all science can offer is conjecture. Science has proven nothing that negates the Genesis record. In fact, the Genesis record answers the mysteries of science.
A clear pattern for interpreting Genesis is given to us in the New Testament. If the language of early Genesis were meant to be interpreted figuratively, we could expect to see Genesis interpreted in the New Testament in a figurative sense. After all, the New Testament is itself inspired Scripture, so it is the Creator's own commentary on the Genesis record.
What do we find in the New Testament? In every New Testament reference to Genesis, the events recorded by Moses are treated as historical events. And in particular, the first three chapters of Genesis are consistently treated as a literal record of historical events. The New Testament affirms, for example, the creation of Adam in the image of God (James 3:9).
Paul wrote to Timothy, "Adam was formed first, then Eve. And Adam was not deceived, but the woman being deceived, fell into transgression" (1 Timothy 2:13-14). In 1 Corinthians 11:8-9, he writes, "Man is not from woman, but woman from man. Nor was man created for the woman, but woman for the man."
Paul's presentation of the doctrine of original sin in Romans 5:12-20 depends on a historical Adam and a literal interpretation of the account in Genesis about how he fell. Furthermore, everything Paul has to say about the doctrine of justification by faith depends on that. "For as in Adam all die, even so in Christ all shall be made alive" (1 Corinthians 15:22). Clearly Paul regarded both the creation and fall of Adam as history, not allegory. Jesus Himself referred to the creation of Adam and Eve as a historical event (Mark 10:6). To question the historicity of these events is to undermine the very essence of Christian doctrine.
Moreover, if Scripture itself treats the creation and fall of Adam as historical events, there is no warrant for treating the rest of the creation account as allegory or literary device. Nowhere in all of Scripture are any of these events handled as merely symbolic.
In fact, when the New Testament refers to creation, (e.g., Mark 13:19; John 1:3; Acts 4:24; 14:15; 2 Corinthians 4:6; Colossians 1:16; Hebrews 1:2, 10; Revelation 4:11; 10:6; 14:7) it always refers to a past, completed event--an immediate work of God, not a still-occurring process of evolution. The promised New Creation, a running theme in both Old and New Testaments, is portrayed as an immediate fiat creation, too--not an eons-long process (Isaiah 65:17). In fact, the model for the New Creation is the original creation (cf. Romans 8:21; Revelation 21:1, 5).
Hebrews 11:3 even makes belief in creation by divine fiat the very essence of faith itself: "By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible." Creation ex nihilo is the clear and consistent teaching of the Bible. | <urn:uuid:dcc0acf3-a142-466a-a87b-f000ef4f76ec> | http://www.gty.org/resources/articles/A160/genesis-1-and-biblical-authority |
The CEI is currently involved in many international space missions and projects.
Gaia: Gaia was adopted within the scientific programme of the European Space Agency (ESA) in October 2000. The mission aims to: measure the positions of ~1 billion stars both in our Galaxy and other members of the Local Group, with an accuracy down to 20 µas, perform spectral and photometric measurements of all objects, derive space velocities of the Galaxy's constituent stars using the stellar distances and motions, and create a three-dimensional structural map of the Galaxy. The gathered large datasets will provide astronomers with a wealth of information covering a wide range of research fields: from solar system studies, galactic astronomy, cosmology to general relativity. The CEI is involved in a number of different projects including modelling the CCDs designed for the Gaia mission to simulate the charge trapping effect of radiation damage, analysis of the BP/RP and RVS radiation campaign datasets and the development of the data processing pipeline.
IXO: The International X-ray Observatory (IXO) is a new X-ray telescope with joint participation from NASA, the European Space Agency (ESA), and Japan's Aerospace Exploration Agency (JAXA). This project supersedes both NASA's Constellation-X and ESA's XEUS mission concepts. IXO is a next-generation facility designed to examine three main areas: black holes and matter under extreme conditions, formation and evolution of galaxies, clusters and large scale structure, and the life cycles of matter and energy. The IXO optics will have 20 times more collecting area at 1 keV than any previous X-ray telescope. The focal plane instruments will deliver up to 100-fold increase in effective area for high resolution spectroscopy from 0.3-10 keV, deep spectral imaging from 0.2-40 keV over a wide field of view, unprecedented polarimetric sensitivity, and microsecond spectroscopic timing with high count rate capability. The CEI is currently developing instrumentation for the X-ray Grating Spectrometer (XGS) readout.
Euclid: Euclid is a medium class mission candidate for launch in 2017 as part of the Cosmic Vision 2015-2025 programme and will spend five years in orbit at L2. The mission is a combination of two missions: the Dark UNiverse Explorer (DUNE) and the SPectroscopic All Sky Cosmic Explorer (SPACE). The primary goal is to study the dark universe by means of two main cosmological probes: the Weak Lensing (WL) technique which maps the distribution of dark matter and measures the properties of dark energy in the universe and the Baryonic Acoustic Oscillations (BAO) technique which uses the scales in the spatial and angular power spectra as "standard rulers" to measure the equation of state and rate of change of dark energy.
The CEI is working with a number of institutes, including ESA and Mullard Space Science Laboratory (MSSL) on the characterisation of the radiation effects to the Euclid CCDs. This work involves pre- and post-irradiation characterisation of the e2v CCD204s provided by ESA, based on the same architecture as the CCD203 which is proposed to be used onboard Euclid. A model of the CCD204 pixel structure is being created to explore the electron density for charge storage as a function of signal size and being used in CTE simulations under a variety of signal conditions to predict CTE effects at the mid and end of mission. The aim is to provide recommendations on CCD design modifications for improved radiation tolerance, device operation and shielding.
Chandrayaan-1 & 2: The Indian Space Research Organisation Chandrayaan-1 spacecraft was launched on the 22nd of October 2008. It spent nine months in a 100 km circular orbit around the Moon before communication was lost. During this time it surveyed the around 15 percent of the lunar surface providing a map of chemical characteristics and 3-dimensional topography. The spacecraft carried a number of instruments including a terrain mapping camera, infrared spectrometers, and the Chandrayaan-1 X-ray Spectrometer (C1XS). The C1XS instrument consisted of 24 e2v technologies CCD54 swept-charge device silicon X-ray detectors arranged in 6 modules that will carried out high quality X-ray spectroscopic mapping of the Moon using the technique of X-ray fluorescence in the energy range 0.5-10 keV.
The CEI was involved in performing the proton radiation damage assessment for the CCD54 devices recommending instrument shielding, operating temperature and operating potentials. The pre-flight characterisation of the 14 modules available for flight selection was also conducted recommending ten modules suitable for use in the instrument. The ESA space environment information system (SPENVIS) software was utilised to estimate the worse case end of life 10 MeV equivalent proton fluence, which was used to irradiate a number of CCD54 devices to investigate their post irradiation performance. The CEI continues to be involved in the instrument in an advisory role on the observed radiation effects to the CCD54 devices.
Chandrayaan-2 is the second Indian lunar mission, to be launched in 2014 into a 200 km polar orbit where is will use and test various new technologies. The spacecraft will include a number of instruments, one being the Chandrayaan-2 Large Area Soft X-ray Spectrometer (CLASS) instrument which is a continuation of the successful C1XS instrument. CLASS will map the abundance of major rock forming elements on the lunar surface, mapping elemental abundances with a nominal spatial resolution of 25 km. The instrument uses the second generation swept charge device, CCD236, and has a geometrical area three times that of C1XS which will allow for data collection at low levels of solar activity.
The CEI will provide assistance with the characterisation of the SCDs and an analysis of the impact of radiation damage on their performance. Initial studies have demonstrated a factor of two improvement in radiation hardness, further optimisation and a more detailed investigation into device performance is currently underway.
UKube-1: The UK Space Agency is planning to launch their first cubesat later this year. The cubesat platform allows fast mission turnaround of small payloads, allowing more groups to be involved with the missions. After launch in late 2011, the satellite will spend 1 year in a low Earth orbit (~400km), with a view to operating for a further 2 years if successful.
The CEI has successfully bid for design and production of a single payload, working in tandem with Clydespace to develop a payload responsible for imaging of the Earth with narrow and wide field imagers. In addition the group plans to include an imager to monitor radiation damage effects on the 0.18µm CMOS sensors, which have been previously characterised on the ground. This is the first such instrument under total development by the group, and will provide ample training and expansion of knowledge of mission development within the group.

Yes, let's start with the basics:
What are the typical mistakes people make with percentages?
What is the margin of error in a poll?
It would be virtually impossible to conduct a poll on the entire voting population in the United States. Pollsters therefore question a sample of a population.
What is the difference between causation and correlation?
One of the most common errors we find in the press is the confusion between correlation and causation in scientific and health-related studies.
What does it mean for a result to be “statistically significant”?
How can we tell whether two events happen at the same time by chance, or for a reason?
What is the difference between absolute and relative risk?
Which one tells you about the actual risk ?
What is the difference between controlled, observational and case controlled studies?
There are advantages and disadvantages to each type, and an awareness of these differences makes for a savvier consumer of public health information.
What are confounding factors and how do they affect studies? | <urn:uuid:b95458ac-04cb-4ade-8e9f-3c0d35a9a1ac> | http://www.stats.org/in_depth/faq/FAQ_intro.htm |

Reemergence of Human and Animal Brucellosis, Bulgaria
Bulgaria had been free from brucellosis since 1958, but during 2005–2007, a reemergence of human and animal disease was recorded. The reemergence of this zoonosis in the country highlights the importance of maintaining an active surveillance system for infectious diseases that will require full cooperation between public health and veterinary authorities.
According to the World Health Organization (1), brucellosis is one of the most common zoonoses worldwide and is considered a reemerging infectious disease in many areas of the world. An estimated 500,000 new human cases occur annually worldwide (2). In Europe, 1,033 human brucellosis cases were reported in 2006 (3); data from a passive surveillance system were based on clinical findings, supported by epidemiologic criteria, and confirmed by serologic tests. Here we report the results of a survey performed in Bulgaria during 2005–2007, which has been considered free from Brucellosis melitensis and B. abortus disease since 1958 (4).
In Bulgaria, until 1998 serologic screening was mandatory for all cattle, sheep, and goats >12 months of age. Afterward, based on risk assessment, animal surveillance activities covered 100% of heads reared in municipalities along the borders with countries endemic for brucellosis such as Turkey, Greece, and the former Yugoslav Republic of Macedonia; 50% of the animals reared in other municipalities of the regions bordering the aforementioned countries; and 25% of animals reared in the inner Bulgarian regions. Currently, an active surveillance system is in place for dairy factory employees and persons considered at risk after outbreaks in ruminants.
During 2005–2007 (Figure 1), a total of 105 human cases of brucellosis were diagnosed among 2,054 persons who were tested on the basis of clinical suspicion or risky exposure. A human case of brucellosis was considered confirmed if results of serologic tests, such as ELISA or complement fixation test, were positive, in accordance with the World Health Organization case definition (5). Bacteria isolation and characterization had not been performed routinely.
The alert started in 2005 (Figure 1, panel A), when a case of brucellosis occurred in a Bulgarian migrant animal keeper working in Greece. Active surveillance of persons at risk was implemented, enabling detection of a total of 34 human cases of brucellosis. All cases were classified as imported cases; therefore, no supplemental active surveillance on animals was implemented. Additionally, during routine screening for at-risk workers, 3 other persons employed in a dairy factory were found to be seropositive. Due to the lack of traceability of the raw material used in the factory, it was not possible to trace the origin of the infection. At that time, there was no evidence of animal cases of brucellosis.
During 2006 (Figure 1, panel B), a total of 10 cases of human brucellosis were reported from different regions of the country. According to anamnestic information, these case-patients had different sources of infection: 3 of the 10 were considered imported infections; 1 case-patient was diagnosed during hospitalization in Sicily (Italy), where the patient reported having eaten ricotta cheese, and 2 occurred in Bulgarian migrant animal keepers working in Greece. Concerning the origin of infection, epidemiologic data suggest that 5 of the 10 cases were related to occupational risk and the remaining to consumption of raw milk and milk derivates. Surveillance activities enabled detection of 10 animals (7 small ruminants and 3 cows) with positive serologic results; these animals were then killed and destroyed. During 2007 (Figure 1, panel C), a total of 58 human cases were identified. Of 58 cases, 54 were classified as autochthonous (i.e., acquired by imported animals found to be infected during regular veterinary surveillance). These cases were identified in a Bulgarian region bordering Greece and Turkey (Haskovo region).
Two other cases, which were also classified as autochthonous, were diagnosed in patients who stated they had consumed a risky product (i.e., raw milk handled without adherence to hygienic standards). The remaining 2 cases were classified as imported because they involved Bulgarian migrant animal keepers working in Greece. Active surveillance in place for animals found a total of 625 heads (618 small ruminants, 7 cows) with positive serologic results; all were killed and destroyed. Analagous with what we observed in humans, most of the infected animals were found in the Haskovo region. All animals found to be infected during surveillance activity were bred at the family farm, and their milk and dairy products were prepared and eaten without adherence to proper hygienic standards.
Our data show that brucellosis is reemerging in Bulgaria (Figure 2). On the basis of information provided in this report, we can make several hypotheses regarding the causes of the resurgence of a previously controlled infection in a transitional, rapidly changing country.
Overall, 105 human cases of human brucellosis were identified over a 3-year period. Of them, 84 cases (80%) were identified in persons at occupational risk. This finding suggests that when brucellosis is introduced into naive territories (i.e., those territories that were considered officially free of brucellosis), the primary source of infection for humans is direct contact with infected animals (i.e., exposure to abortion/delivery products) or domestic consumption of products produced on family farms (milk, raw cheese). However, environmental exposure can also occur, especially in infants and children, who are considered at lower risk for direct contact with potentially infected animals, as recently observed (6). This hypothesis appears to be consistent with the context of a naive setting, where preventive measures are not routinely implemented. Continuous health education and other strategies may contribute to reduce the circulation of human brucellosis in endemic areas (7).
The reemergence of brucellosis is not limited to Bulgaria but involves several countries in the Balkan region and even in the Caucasian region (P. Pasquali, unpub. data). This trend or reemergence has several explanations. First, due to socioeconomic changes, many countries in these regions are experiencing a dramatic increase of animal trade, animal movement, and occupational migration, which in turn may increase the risk for introduction and spread of infectious diseases, such as brucellosis, from other disease-endemic countries like Greece or Turkey (2). Second, the process that has characterized the change of the social and administrative organization since the collapse of the Soviet Union is far from being completed; the public health systems are still flawed in many countries. Finally, part of the increase may simply be that brucellosis is a complex disease, which has different cycles of expansion and regression.
Before drawing conclusions, we should mention 2 possible limitations of the study. First, samples from patients with positive serologic results were used for bacterial culture for brucellosis only if sample collection was properly timed; no culture positive case is available. Second, we cannot exclude the possibility that part of the increase in cases of brucellosis could be due to improved surveillance; in particular, temporal trends and geographic comparison might be, to some extent, affected by the intensity of screening activities. However, this increased surveillance is unlikely to bias the observed shift from imported to locally acquired cases.
In conclusion, this report shows how a disease such as brucellosis may increase its public health impact, particularly in transitional countries such as Bulgaria. Our findings emphasize the importance of the combination of health education and active surveillance systems for controlling infectious diseases and highlight the need for cooperation between public health officials and veterinary officers. Creating and improving capacity building are necessary to properly address issues that pose public health hazards.

Charles Heywood kept his cannon firing even as his ship sank.
Born in Waterville on Oct. 3, 1839, Heywood was commissioned a second lieutenant in the United States Marine Corps at New York City on April 5, 1858. Thirty-five months later he reported aboard the USS Cumberland, a 24-gun sloop of war then assigned to the Gosport Navy Yard in Portsmouth, Va.
Fearing the shipyard’s capture by Confederate militia, senior Navy officers ordered Gosport abandoned on April 20, 1861. After mining key installations with barrels of gunpowder, Heywood and his Marines lit the fuses and hastened aboard the USS Cumberland, already slipping seaward on the ebbing Elizabeth River.
The resulting explosions and fires caused significant damage, but Confederate engineers quickly repaired crucial machinery. They also raised the burned and scuttled USS Merrimac. Upon its hull arose an ironclad, the CSS Virginia. Measuring 263 feet in length and weighing 3,200 tons, the steam-engine ironclad mounted 10 massive cannons. The skipper was Capt. Franklin Buchanan.
He intended to sail into Hampton Roads and sink the Yankee warships stationed there. By the time Buchanan ordered his ship to sail on March 8, 1862, Heywood was a captain commanding the USS Cumberland’s Marine contingent.
Brilliant late-winter sunshine and warm air engulfed Hampton Roads as the CSS Virginia stood downriver that Saturday. Buchanan had already selected his first target. “I am going to ram the Cumberland,” which was equipped with “the new rifled guns, the only ones in their whole fleet we have cause to fear,” he told Chief Engineer H. Ashton Ramsay. “The moment we are out in the Roads, I’m going to make right for her and ram her.”
That morning, the USS Cumberland lay moored some 300 yards off Newport News on the north shore of Hampton Roads. Aboard the Cumberland, Cmdr. William Radford had gone ashore, leaving Lt. George Morris, the executive officer, in command.
At noon, sailors on watch aboard the Cumberland “discovered three vessels under steam, standing down the Elizabeth River toward Sewell’s Point,” Morris wrote on March 9. One ship belched black smoke; Morris, Heywood, and other USS Cumberland officers could see the smoke without using their spyglasses.
Buchanan’s underpowered ironclad steamed ponderously into Hampton Roads. After the CSS Virginia cleared Sewell’s Point about 1:30 p.m., Buchanan steered west to attack the USS Cumberland.
Aboard that ship, crewmen had already “double breeched the guns on the main deck, and cleared [the] ship for action,” Morris reported. He ordered the sloop pivoted on her anchor so that her starboard broadside would face the ironclad.
Assigned to his ship’s after gun division, Heywood stood with his gun crews and watched as the Virginia approached. At 2 p.m. aboard the ironclad, Lt. Charles Simms fired the bow pivot gun, a 7-inch Brooke rifle.
According to William C. Davis writing in “Duel Between the First Ironclads,” Simms’ cannon ball “screamed across the Roads and hit” the USS Cumberland “squarely, passing through the starboard-quarter rail” and hurling wood splinters into nearby Marines. After a Cumberland gun crew fired their ship’s forward 10-inch pivot gun and missed, Simms’ second shot exploded amidst that gun crew and killed all but two men.
“Our firing became at once very rapid from the few guns we could bring to bear” as the ironclad “approached slowly,” recalled Master Moses Stuyvesant, who commanded the sloop’s after gun division. Simms’ pivot gun pounded the Cumberland; as shell fragments and wood splinters struck down sailors and Marines alike, Heywood’s crews fired their cannons through the dense smoke.
At approximately 2:30 p.m., Cumberland pilot A.B. Smith thought the approaching ironclad resembled “a huge half-submerged crocodile” with its “iron ram projecting, straight forward.”
Steaming at 6 knots, the Virginia “stood on and struck us under the starboard fore channels” near the Cumberland’s bow, Morris reported. “She delivered her fire at the same time; the destruction was great. We returned the fire with solid shot with alacrity.”
The ironclad’s ram opened a hole about 7 feet across. Flooding with seawater, the USS Cumberland listed to starboard — and the ship’s weight bore the Virginia downward.
The ironclad was already reversing its engines as the tide pivoted the trapped Virginia alongside the sinking Cumberland. Then the ram broke off, freeing the ironclad from a potential watery grave. Buchanan backed his ship until it lay parallel to the Cumberland and only 20 feet away.
Cannons flashed and boomed for some 30 minutes as Heywood and his comrades heroically fought the Virginia amidst “a scene of carnage and destruction never to be recalled without horror,” Stuyvesant remembered. Blood and gore splattered across the main deck as Heywood shouted at sailors and Marines to drag wounded comrades to the ship’s port side.
Now the sea lapped at the Cumberland’s main deck as the bowsprit disappeared into Hampton Roads. Gun crews kept firing until their cannons submerged. Stationed near the stern, Heywood worked his guns even as another cannon broke loose and lurched across the deck to crush a sailor.
“At 3:35 [p.m.] the water had risen to the main hatchway, and the ship canted to port, and we delivered a parting fire, each man trying to save himself by jumping overboard,” Morris recalled. Acknowledging that severely wounded men taken below decks could only be left to drown, he credited specific officers for their coolness under fire.
“I can only say in conclusion that all did their duty and we sunk with the American flag at the [mast] peak,” Morris closed his report.
Even as the Cumberland’s deck sharply canted, Heywood remained with the aft guns. “The water began to swash over the upper deck, and still every unencumbered gun was hurling defiance at the foe,” wrote John S.C. Abbott in “The History of the Civil War in America, Vol. 1,” published in 1863.
“The ship careened upon one side. The last gunner [Heywood], knee-deep in water, pulled the trigger of the last gun,” Abbott wrote. Then “the majestic frigate, with all her dead and all her wounded, sank like lead.”
And Charles Heywood went overboard into Marine Corps lore.
His heroism went noticed. “I omitted to mention to you the gallant conduct of Lieutenant Charles Heywood … whose bravery upon the occasion of the fight with the Merrimack won my highest applause,” Morris wrote Navy Secretary Gideon Welles on April 12.
Heywood received a brevet promotion to major after the battle. Of the 46 Marines aboard the USS Cumberland, 14 died. Another 107 sailors were killed aboard the sloop on March 8.
The next day, the Monitor fought the Virginia in Hampton Roads in history’s first ironclad-to-ironclad sea battle. Most history books still call the Virginia the “Merrimac.”
Heywood would fight during another famous Civil War battle; he was commanding two gun crews aboard the USS Hartford at Mobile Bay, Ala. as Adm. David Farragut roared, “Damn the torpedoes! Full speed ahead!” on Aug. 5, 1864. Within an hour, Heywood and Farragut traded shot and shell with another Confederate ironclad, the CSS Tennessee — commanded by Adm. Franklin Buchanan.
This time Buchanan lost and Heywood won.
Named the ninth Marine Corps commandant on Jan. 30, 1891, Charles Heywood instituted important changes to the corps’ mission and strength. Promoted to major general a year before his 1903 retirement, he died at Washington, D.C., on Feb. 26, 1915. His wife, Caroline Bacon, outlived him by 12 years.
Heywood lies buried in Section 2, Lot 1115 at Arlington National Cemetery.

"One death is a tragedy. A million deaths is a statistic." -Joseph Stalin
When figuring out how people will respond to a foreign tragedy, it comes down to three things: location, location, location.
And TV cameras too.The September 11, 2001 homicide attacks
killed about 3,000 people yet it's had more impact on American politics and foreign policy than anything since World War II. And to the great extent that American foreign policy impacts the rest of the world, it had a huge impact on international affairs as well.
While 3,000 is pretty big death toll for a single incident, there have been other wars and attacks with greater loss of life that had a relatively miniscule influence on American or international affairs. Why? Because those attacks didn't occur in the heart of New York City. The international response would've been significantly less if the attack had been launched in Kathmandu, Bogota or Algiers (in countries with homegrown terrorist problems).The Asian tsunami of 2004
had a devastating effect and cost an estimated 283,000 lives and over a million displaced. It generated an international response that was probably unprecedented in scale. As someone who regularly reads articles on underfunded international crisis appeals, I was heartened by the response to the tsunami. That it hit easily accessible coastal regions, including many tourist areas, made it easier to TV crews to get images. That Europeans and Americans were amongst the victims, if a tiny fraction, ensured that it got coverage in the western media.
But if I told you there was a conflict that has cost almost 15 times as many lives as the tsunami, could you name that crisis? If I told you there was a crisis that, in mortality terms, was the equivalent of a three 9/11s every week for the last 7 years
, would you know which one I'm talking about?
I bet few westerners could, even though it's by far the deadiest conflict of the last 60 years.
The war in the Democratic Republic of the Congo (formerly Zaire) is killing an estimated 38,000 people each month, according to the British medical journal The Lancet
. And if not for the involvement of humanitarian non-governmental organizations and UN relief agencies, the toll would be much higher.Most of the deaths are not caused by violence but by malnutrition and preventable diseases after the collapse of health services, the study said
, notes the BBC. Since the war began in 1998, some 4m people have died, making it the world's most deadly war since 1945, it said.
A peace deal has ended most of the fighting but armed gangs continue to roam the east, killing and looting.
The political process in the DRC is slowly inching in the right direction. Voters in the country recently approved a new constitution
, to replace the one imposed on it by the outgoing Belgian colonialists. EU officials praised the referendum as free and fair, probably the first truly open poll in the country's history. Elections are scheduled for June of this year.
However, instability reigns in much of the country, particularly the east. And central government throughout the entireity of the country has never been strong in this gigantic country. There are 17,000 UN peacekeepers doing the best they can but the country's the size of Western Europe. (By contrast the Americans and British have ten times as many troops in Iraq, a country that's less than 1/5 the size of the DRC. And we know how many problems they're having there)
And this shows why war should ALWAYS be a last resort. Most of the deaths have not been directly caused by war
(bullet wounds, landmines, etc). Most of the deaths have been caused by factors provoked by war's instability and destruction. The destruction of all infrastructure like roads and medical clinics. The inability to get to sources of clean water. The fear of leaving the house to tend the fields or go to the market.
38,000 people a month. If you get pissed off at Howard Dean or Pat Robertson, spare a little outrage for this.
And maybe a few bucks.

There isn't a huge difference in the way residential homes are built in Japan compared to in the U.S., although the Japanese are more likely to invest in special earthquake engineering, particularly in commercial and higher-end residential buildings.
Home builders in both Japan and the U.S. use a lot of wood-frame construction, which is flexible and tends to ride out a quake fairly well, said Heidi Faison, outreach director at the Pacific Earthquake Engineering Research Center in Berkeley, Calif. But wood frame structures do have potential vulnerabilities in two key areas: the foundation and the wall that supports a crawl space, which is called a cripple wall.
She recommends home buyers hire an engineer to make sure the wood frame is bolted to the foundation. If a house has a crawl space underneath it or you need to climb a few steps to get up to the first floor, it likely is supported by a cripple wall, which can buckle in an earthquake. If you're in an earthquake-prone location, that space needs to be filled in with a solid material.
Gary Ehrlick, a structural engineer and program manager for Structural Codes & Standards at the National Association of Home Builders, outlines some other house features to consider:
• Look at the garage, if the house has one. A large garage door opening or a lot of big windows on the first floor, that can create a soft story -- an open space without enough support to withstand violent shaking.
• Brick veneer can present a major hazard if it's not attached well. Brick was a problem in the 6.3 magnitude temblor that struck New Zealand last month. "It doesn't create as much of a hazard inside, but outside it can injure or kill,'' he said.
• Houses built on a slope are often an issue. They need to be tied back well with footings. Also make sure the slope is stable. Liquefaction -- where saturated soil becomes liquid -- can be a problem and can occur when a building is located near a lake or river. In an earthquake, liquefaction can cause the ground to behave like quicksand, as seen in New Zealand and in the 1989 earthquake in Loma Prieta in the mountains of Santa Cruz, Calif.
In Japan, most of the damage was actually inflicted by the subsequent tsunami, just as most of the destruction in the San Francisco quake of 1906 was caused by fires that ripped through the city after gas lines were ruptured.
A disaster's chain of events makes the preparation scenario a bit more complicated.
There is a growing interest in designing homes better able to survive a tsunami. The basic idea in tsunami design, as in flood-resistant construction is to get some of your structure up above the expected level of water, said Gary Ehrlick.
"In commercial structures they talk about vertical evacuation zones.'' Under this theory, the first floor, built out of concrete or steel, is strong enough to withstand the pressure of the water. The "zone of refuge'' occupies the upper floors.
Another concept that came out of the earthquake/tsunami that leveled Banda Aceh, Indonesia, on Check out our gallery of Day in 2004 is a house where the first floor allows the wave to wash through it, destroying the walls but preserving the foundation. This would be a concrete frame with columns or wall segments in each corner of the house. The walls are panels made out of something light, like bamboo or wood. After a disaster, such panels would be easy to replace.

Tomorrow, in Philadelphia, Queen's University professor Arthur B. McDonald is scheduled to receive a half-share of the Benjamin Franklin Institute's annual physics prize. It is the latest in a long series of honours for Prof. McDonald, who was the director of the Sudbury Neutrino Observatory (SNO). As one of the oldest internationally recognized honours for research achievements, the Franklin Medal puts him on an altogether new plane, amidst what the French call les nobelisables.
The scientific prestige surrounding the SNO, which ceased collecting data in November of last year, is still growing. As an experiment, it performed exactly as promised, and in an environment of institutional cost-cutting, it did so at a cost (about $70-million) much lower than that required by other particle-physics projects around the world. For every plaudit the SNO receives, there are hundreds, perhaps thousands of Canadians eligible for a share of reflected glory. They ranged from the dozens of physicists who worked on the data-crunching, to the federal bureaucrats who recognized SNO's value and steered clear of it with their budget axes, to the executives at Inco who arranged to set aside space for the project a mile and a half down in the company's Creighton Mine. And let's not forget the miners, who went down into the pit with physicists every day, and during a 1997 strike allowed them to cross a picket line in order to continue their work.
All this was done in the name of hunting the elusive neutrino, a subatomic particle that has no electrical charge and that passes through almost all matter without being stopped or deflected. The existence of neutrinos had been predicted in 1930, and they were first detected in nature as early as 1956, but 40 more years of research had left scientists uncertain whether they possessed any mass. Meanwhile, the sun's interior, a naturally occurring fusion reactor, seemed to be producing only about one-half to one-third as many neutrinos as the so-called Standard Model of particle physics predicted.
The "solar neutrino" problem was a big one. It seemed that scientists would either be required to revise their existing inferential images of the sun's interior, or to do away with the Standard Model itself. For a while it seemed possible that the sun was a lot cooler on the inside than anyone had thought, a discovery that would have had consequences for the ultimate fate of the solar system. Fortunately, when physicists began looking for ways the Standard Model could be modified to allow for the mysteriously low rate of solar neutrino emissions, they realized that if neutrinos did have mass, they were capable of flipping freely in space between three different "flavours" --only one of which earlier neutrino observatories had been capable of observing.
On June 18, 2001, the SNO -- basically a giant tank of heavy water surrounded by cameras that could detect the "flash" created by a single neutrino penetrating to the Earth's core -- solved all of these problems with the release of just one batch of results. It turned out that neutrinos do have mass, that Earth is receiving all three types of neutrinos from the sun and that the total number agrees with established models. Nobel laureate John Bahcall described the discovery in 2004 as "epochal", "revolutionary" and the "fingerprints on the smoking gun" of the solar-neutrino problem.
In the future, the discoveries that the SNO made possible may be placed on a par with Ben Franklin's own research into electricity. Already "neutrino astronomy" is an important field; detectors like SNO will give astronomers early warning of the next supernova in our galactic neighbourhood. As the SNO's "smoking gun" showed, neutrino detection is like having an extra sense to work with when it comes to understanding the solar core. And futurists are spinning wild ideas for neutrinobased imaging and telecommunications -- ideas that now seem as far-fetched, but just as tempting, as alternating current would have been to Franklin. | <urn:uuid:622fd98a-2358-496d-a4f9-c05904f2f98c> | http://www.canada.com/nationalpost/news/editorialsletters/story.html?id=985ca9fe-544f-4e4b-9781-8520ee334122 |

European hypersonic civil transport project heats up as three concepts undergo trials
An aircraft capable of flying five times the speed of sound and reaching Sydney in between two and four hours from Brussels is the leading design in a €7 million European research project to find a hypersonic civilian airliner replacement to the supersonic Concorde.
A Mach 5 civil transport aircraft designed by a UK team is leading a pack of three concepts undergoing preliminary studies for the three-year, €7 million ($9 million) European hypersonic research project, Long Term Advanced Propulsion Concepts and Technologies (LAPCAT).
With €4 million from the European Commission and the rest from industry, LAPCAT aims to develop a vehicle capable of travelling from Europe to Australia in 2-4h.
Oxfordshire-based Reaction Engine says its A2 (a Flight artist's impression of which is pictured above), meets take-off noise restrictions and is powered by hydrogen-fuelled turbine-based combine cycle (TBCC) engines.
The other two concepts are an EADS Mach 8 vehicle with rocket-based combined cycle propulsion and German aerospace research centre DLR’s kerosene-fuelled, TBCC-powered Mach 4 craft.
LAPCAT is being co-ordinated by the European Space Agency for the EC. “Results so far show [the Mach 5 vehicle from Reaction Engines] can avoid later [technology] pitfalls and could travel from Brussels to Sydney,” says ESA’s LAPCAT project co-ordinator Johan Steelant. Criteria for vehicle evaluation include safety, ability to reach diversion airports, adaptability to different sonic boom restrictions and technological maturation. Steelant cites the heat exchangers in Reaction Engine’s Scimitar TBCC engine as being more advanced in their development.
Later this month tests of an experimental engine intake will start at a DLR windtunnel facility. These should be followed by nozzle tests in July and eventually combustion chamber and combined intake, chamber and nozzle testing. | <urn:uuid:ad4b1c63-1790-43d9-9298-4305eca41fb6> | http://www.flightglobal.com/news/articles/eu-7m-hypersonic-research-plan-considers-uk-designed-mach-5-aircraft-to-fly-brussels-to-sydney-in-207225/ |
Matisse: Radical Invention, 1913-1917
July 18–October 11, 2010
Matisse conceived this "souvenir of Morocco" in 1912, stretched a canvas for it in 1913, and returned to the composition late in 1915, only to start again on a new canvas in early 1916. Black is the principal agent, at once simplifying, dividing, and joining the three zones of the canvas: the still life of melons and leaves on a gridded pavement, bottom left; the architecture with domed marabout, top left; and the figures, at right. Next to a seated Moroccan shown from behind, the large curving ocher shape and circular form derive from a reclining figure in the sketches. Above the shadowed archway, figures in profile may be discerned in the two windows: at right, the lower part of a seated man; at left, the upper part of a man with raised arms. Matisse built up the surface with thin layers of pigment, the color of the underlying layers modifying those on top. Painter Gino Severini reported that "Matisse said . . . that everything that did not contribute to the balance and rhythm of [this] work, had to be eliminated . . . as you would prune a tree."
Matisse developed this painting of what he described as “the terrace of the little cafe of the casbah” in the years following two visits to Morocco, in 1912 and 1913. As he worked on various studies he eliminated details he felt were extraneous to the painting’s overall balance. A balcony with a flowerpot and a mosque behind it are at upper left, at lower left is a still life of vegetables, and to the right is a man wearing a round turban, seen from behind. Matisse’s generous application of black paint helps unify the three sections of the painting across its abstract expanse.
Matisse: Radical Invention, 1913–1917, July 18–October 11, 2010
Director, Glenn Lowry: Matisse first conceived this painting in 1912, while he was visiting Morocco. But he didn't actually start the canvas until early 1916. Once he did, he continued working on it—with great focus and concentration—through the fall.
Curator, John Elderfield: The forms are difficult to decipher. I know some people who have thought that what Matisse says are melons and leaves are in fact the Moroccans, but Matisse is insistent that they are not. I think one can clearly see the figure whose back is towards us. And if we look at it carefully we can see that that figure's grown in size. To the right of it, that black area does seem to derive from drawings of an arched doorway with light hitting the bottom, but the top part is in shadow, leading into another architectural space. And the two elements at the top are ones which we can trace back to drawings he made in Morocco—the one at the right, of a sort of seated figure, and the one to the left, more puzzling, but somewhat amusingly, in one of the drawings—and he refers to this in his letter—is of a figure who has got his arms raised to look through binoculars. All that remains is the forearms and part of the body, and Matisse is quite happy to have carried it to that point of almost unintelligibility. But I don't think the painting asks us to be specific about these forms.
Curator, Stephanie D’Alessandro: I don't think so either. I think there's a level of memory and recollection, and maybe even nostalgia with this picture.
Glenn Lowry: One aspect of Morocco that stayed with Matisse was the harsh contrast between the midday sun and the shade, evoked here in the black background.
Conservator, Michael Duffy: You can see how it defines certain shapes. Particularly the shape in the middle, this curved shape, which is made up of ochre and white. The black edge on the left is painted over, so he actually defines the form further by overlaying the black paint. When you look closely at the black paint, you'll see that it covers areas of blue and pink underneath, and that gives the black a very warm color. And it's very typical of the way Matisse painted. Rather than blending his colors together, to achieve one color, he would typically layer colors, even black, over several layers, in order to build up a kind of rich, optical surface.
MoMA Audio: Collection, 2008
Curator Emeritus, John Elderfield: This painting was made in 1915–1916 and is a remembrance of visits that Matisse made to Morocco. And while the paintings made in Morocco are beautifully, limpidly colored, obviously the remembrance is rather of the great heat, of contrasts of color in the conditions of very bright light.
The Moroccans themselves are on the right on the terrace with their melons and gourds—the green and yellow forms at the left. We can see a figure with his back to us, and then, with more difficulty, figures in windows at the top. In the background is a mosque with a vase of blue and white flowers standing on the parapet.
Matisse said that he put black in his pictures to simplify the composition. And indeed, through the teens and into the 1920s, he regularly puts in a little dosing of black to hold everything else in place. I think, unquestionably, he was thinking of shadow, and of the kind of stifling midday sun in North Africa. There is that element of renunciation of color and wanting to put in an element of real gravity in the composition. Its hard to imagine any other color doing it in that same way.
The Museum of Modern Art , MoMA Highlights, New York: The Museum of Modern Art, revised 2004, originally published 1999, p. 79
The Moroccans marvelously evokes tropical sun and heat even while its ground is an enveloping black, what Matisse called "a grand black, . . . as luminous as the other colors in the painting." Utterly dense, this black evokes a space as tangible as any object, and allows a gravity and measured drama without the illusion of depth once necessary to achieve this kind of grandeur.
The painting, which Matisse described as picturing "the terrace of the little café of the casbah," is divided into three: at the upper left, an architectural section showing a balcony with flowerpot and the dome of a mosque behind; a still life, of four green-leafed yellow melons at the lower left; and a figural scene in which an Arab sits with his back to us. To his right is an arched doorway, and windows above contain vestigial figures. The form to his left is hard to decipher, but has been interpreted as a man's burnoose and circular turban.
During his visit to Morocco in 1912-13, Matisse had been inspired by African light and color. At the same time, he faced the challenge of Cubism, the leading avant-garde art movement of the period, and The Moroccans summarizes his memories of Morocco while also combining the intellectual rigor of Cubist syntax with the larger scale and richer palette of his own art.
Matisse Picasso, February 13–May 19, 2003
Narrator: In 1911 and again in 1912 Matisse traveled to Morocco. Three years later, he tapped those memories for this big souvenir picture, The Moroccans. By that time he was deeply involved in the Cubist vocabulary of reduced geometric form.
Curator, John Elderfield: What it shows is on the upper left a mosque with a vase of flowers on the right hand side. In the bottom left is a pavement with melons with their green leaves. And at the right, more difficult to figure out, various figures who are presumably sitting on some sort of terrace outside a cafe in Tangier. One can I think clearly understand the figure with his back to us, with a white turban and, blue shirt. And to the right, what looks like the top of an archway in shadow.
Matisse talked about the black as being a way of representing heat and light. And as one gets further south, one gets these very strong black and white contrasts. It's also trying to convey some of the sense of the intense light, and the almost tangible heat of Tangier.
Curator, Kirk Varnedoe: Certainly Picasso must have looked intensely at a major picture like this, and learned from it a new vocabulary of Cubism, more highly abstracted, more monumental. When you compare The Moroccans to Picasso's Three Musicians of 1921...what leaps out at you are certain similarities—the use of black for example. But Picasso unlike Matisse is not a traveler. Picasso often said, "If someone didn't come to the studio in the morning, I wouldn't have anything to paint in the afternoon."
Narrator: The Three Musicians most likely represent the artist and his friends. Picasso himself is at the center, identified by the harlequin costume and guitar he often used as his symbols. To the right, the man dressed as a monk with a stylized beard is probably Picasso's friend the poet Max Jacob, who had entered a monastery after the First World War. And the large white figure with the clarinet may be another poet friend, Guillaume Apollinaire, who had died from war wounds.
Kirk Varnedoe: The picture has a kind of gravity, a kind of sadness or melancholy, which is played off by small and amusing details, like the tiny little zig zags that represent the hand on the notes of music, or the dog that lies under the table to the left. So you imagine the music being played. Is it syncopated like a kind of bright jazz, and on the other hand melancholy like a threnody? And when you compare this in its detail, then you sense how monumental the Matisse is by comparison, and how in a certain sense impersonal it is. | <urn:uuid:2a578a9b-5330-4676-ba04-3ad5f024bf2d> | http://www.moma.org/collection/object.php?criteria=O%3AOD%3AE%3A79588&page_number=1&template_id=1&sort_order=1&background=black |
EARLY SPRING in the Lamar River Valley: several wolves chase elk while an interested grizzly bear awaits the outcome. Grizzlies can drive wolves off a kill; more often they scavenge after the wolves have eaten their fill. Image: DIANE HARGREAVES
Several scrawny cottonwood trees do not usually generate much excitement in the world of ecology. But on a wind-whipped August afternoon in Yellowstone National Park's Lamar Valley, William J. Ripple, a professor of botany at Oregon State University, stands next to a 12-foot-high cottonwood tree and is quietly ecstatic. "You can see the terminal bud scars," the bespectacled Ripple says, bending the limber tree over to show lines that mark a year's growth of a foot or more on the broom-handle-size trunk. "You can see that elk haven't browsed it this year, didn't browse it last year and, in fact, haven't browsed it since 1998."
Ripple gestures at the sprawling mountain valley around us and points out that although numerous other cottonwoods dot the landscape, this knot of saplings comprises the only young ones--the rest of this part of the Lamar is a geriatric ward for trees. The stately specimens that grow in the valley bottom are 70 to 100 years old, and not a newcomer is in sight to take their place. On the hillside, aspen trees present a similar picture. Groves of elderly aspen tremble in the wind, but no sprouts push up in the understory. | <urn:uuid:cdd9b6d4-d9d1-48f3-ad8d-a010794d6115> | http://www.scientificamerican.com/article.cfm?id=lessons-from-the-wolf |
Darfur’s people are a complex mosaic of between 40 and 90 ethnic groups, some of ‘African’ origin (mostly settled farmers), some Arabs. All Darfurians are Muslim. The Arabs began arriving in the 14th century and established themselves as mainly nomadic cattle and camel herders. Peaceful coexistence has been the norm, with inevitable disputes over resources between fixed and migratory communities resolved through the mediation of local leaders. For much of its history, the division between ‘Arab’ and ‘African’ has been blurred at best, with so much intermarriage that all Darfurians can claim mixed ancestry. Identities have been defined in different ways at different times, based on race, speech, appearance or way of life.
An Independent Sultanate
At the heart of Darfur is an extinct volcano in a mountainous area called Jebel Marra. Around it the land is famously fertile, and it was here that the earliest known inhabitants of Darfur lived – the Daju. Very little is known about them. The recorded history of Darfur begins in the 14th century, when the Daju dynasty was superseded by the Tunjur, who brought Islam to the region.
Darfur existed as an independent state for several hundred years. In the mid-17th century, the Keyra Fur Sultanate was established, and Darfur prospered.
In its heyday in the 17th and 18th centuries the Fur Sultanate’s geographical location made it a thriving commercial hub, trading with the Mediterranean in slaves, ivory and ostrich feathers, raiding its neighbours and fighting wars of conquest in the surrounding region.
Darfur under siege
In the mid-19th century, Darfur’s sultan was defeated by notorious slave trader Zubayr Rahma, who was in turn subjugated by the Ottoman Empire. At the time, this included Egypt and what is now northern Sudan. The collapse of the Keyra dynasty plunged Darfur into lawlessness. Roaming bandits and local armies preyed on vulnerable communities, and Islamic ‘Mahdist’ forces fighting British colonial control of the region sought to incorporate Darfur into a much larger Islamic republic. A period of almost constant war followed, until 1899 when the Egyptians – now under British rule – recognized Ali Dinar, grandson of one of the Keyra sultans, as Sultan of Darfur. This marked a de facto return to independence, and Darfur lived in peace for a few years.
Colonial ‘benign neglect’
Ali Dinar refused to submit to the wishes of either the French or the British, who were busy building their empires around his territory. Diplomatic friction turned into open warfare. Ali Dinar defied the British forces for six months, but was ambushed and killed, along with his two sons, in November 1916. In January 1917 Darfur was absorbed into the British Empire and became part of Sudan, making this the largest country in Africa.
The only aim of Darfur’s new colonial rulers was to keep the peace. Entirely uninterested in the region’s development (or lack thereof), no investment was forthcoming. In stark contrast to the north of Sudan, by 1935 Darfur had only four schools, no maternity clinic, no railways or major roads outside the largest towns. Darfur has been treated as an unimportant backwater, a pawn in power games, by its successive rulers ever since.
Independence brings war
The British reluctantly but peacefully granted Sudan independence in 1956. The colonialists had kept North and South Sudan separate, developing the fertile lands around the Nile Valley in the North, whilst neglecting the South, East and Darfur to the west. They handed over political power directly to a minority of northern Arab élites who, in various groupings, have been in power ever since. This caused the South to mutiny in 1955, starting the first North-South war. It lasted until 1972 when peace was signed under President Nimeiry. But the Government continually flouted the peace agreement. This, combined with its shift towards imposing radical political Islam on an unwilling people, and the discovery of oil, reignited conflict in the South in 1983.
Darfur, meanwhile, became embroiled in the various conflicts raging around it: not just internal wars by the centre over its marginalized populations – many of the soldiers who fought for the Government against the South were Darfurian recruits – but also regional struggles. The use of Darfur by Libya’s Colonel Qadafhi as a military base for his Islamist wars in Chad promoted Arab supremacism, inflamed ethnic tensions, flooded the region with weaponry and sparked the Arab-Fur war (1987-89), in which thousands were killed and hundreds of Fur villages burned. The people’s suffering was exacerbated by a devastating famine in the mid-1980s, during which the Government abandoned Darfurians to their fate.
Bashir seizes power
In 1989 the National Islamic Front (NIF), led by General Omar al-Bashir, seized power in Sudan from the democratically elected government of Sadiq al Mahdi, in a bloodless coup. The NIF revoked the constitution, banned opposition parties, unravelled steps towards peace and instead proclaimed jihad against the non-Muslim South, regularly using ethnic militias to do the fighting. Although depending on Muslim Darfur for political support, the NIF’s programme of ‘Arabization’ further marginalized the region’s ‘African’ population.
The regime harboured several Islamic fundamentalist organizations, including providing a home for Osama bin Laden from 1991 until 1996, when the US forced his expulsion. Sudan was implicated in the June 1995 assassination attempt on Egyptian President Mubarak. Its support for terrorists and increasing international isolation culminated in a US cruise-missile attack on a Sudanese pharmaceutical factory in 1998, following terrorist bombings of the US embassies in Nairobi and Dar es Salaam.
The Janjaweed: ‘counterinsurgency on the cheap’
Janjaweed fighters, with their philosophy of violent Arab supremacism, were first active in Darfur in the Arab-Fur war in the late 1980s. Recruited mainly from Arab nomadic tribes, demobilized soldiers and criminal elements, the word janjaweed means ‘hordes’ or ‘ruffians’, but also sounds like ‘devil on horseback’ in Arabic. The ruthlessly opportunistic Sudanese Government first armed, trained and deployed them against the Massalit people of Darfur in 1996-98. This was an established strategy by which the Government used ethnic militias to fight as proxy forces for them. It allowed the Government to fight local wars cheaply, and also to deny it was behind the conflict, despite overwhelming evidence to the contrary.
The Comprehensive Peace Agreement
When President George W Bush came to power in 2000, US policy shifted from isolationism to engagement with Sudan. After 11 September 2001 Bashir ‘fell into line’, started to co-operate with the US in their ‘war on terror’ and a peace process began in earnest in the South. After years of painstaking negotiations, and under substantial pressure from the US, in January 2005 a Comprehensive Peace Agreement (CPA) was signed between the Government and the Sudan People’s Liberation Movement/Army (SPLM/A), ending 21 years of bloody war which killed two million people, displaced another four million and razed southern Sudan to the ground.
A surprisingly favourable deal for the South, the CPA included a power-sharing agreement leading up to a referendum on independence for the South in 2011, a 50-50 share of the profits from its lucrative oilfields, national elections in 2009, and 10,000 UN peacekeepers to oversee the agreement’s implementation. But the ‘comprehensive’ deal completely ignored Darfur, catalyzing the conflict that is currently engulfing the region.
The rebels attack
Rebellion had been brewing in marginalized, poverty-stricken Darfur for years. After decades in the political wilderness, being left out of the peace negotiations was the final straw. Inspired by the SPLA’s success, rebel attacks against Government targets became increasingly frequent as two main rebel groups emerged – the Sudan Liberation Army (SLA) and the Justice and Equality Movement (JEM). By early 2003 they had formed an alliance. Attacks on garrisons, and a joint attack in April on an airbase that reduced several Government planes and helicopters to ashes, were causing serious damage and running rings around the Sudanese army.
Facing the prospect of its control over the entire country unravelling, in 2003 the Government decided to counterattack. Manipulating ethnic tensions that had flared up in Darfur around access to increasingly scarce land and water resources, they unleashed the Janjaweed to attack communities they claimed had links to the rebels.

Evaluating Tagging Methods and Movement Patterns of Round Gobies
The round goby (Neogobius melanostomus) is an invasive fish species introduced in the St. Clair River in 1990 and is now found throughout the Great Lakes basin. Information on round goby movement and behavior is needed to understand their potential impact on the Great Lakes. Research on potential tagging methods and movement of round gobies is scant. We explored the use of marking round gobies with passive integrated transponder (PIT) tags in order to determine the effects of tagging on growth and mortality. In general, we found that the presence of a tag in the fish had no strong effect on growth or mortality. We also conducted a study on the movement patterns of round gobies in Muskegon Lake. Using PIT tagged fish we followed 48 round gobies enclosed in a 20x20-m block net for 22 days. Our goal was to determine the movement patterns of the gobies within the block net and examine the effects of various factors on these patterns. However, during the course the study, we found that the equipment used was not optimal for use with round gobies. Due to a high escape rate and low detection rate of fish, no conclusions could be surmised on round goby movement. Overall, we determined that although PIT tags do not strongly affect the growth or mortality of round gobies, the equipment available currently seems to be inadequate for tracking round gobies in shallow-water, lake habitats.

The Immigration History Research Center is home to thousands of feet of archival records that illuminate the immigrant experience, past and present. While these records are available to students and teachers for research in the University of Minnesota’s Andersen Library, exploring the archive from afar is as simple as connecting to the internet. The IHRC’s collection of digitized archival material provides a plethora of resources suitable for a variety of purposes, including the creation of curriculum for K-12 educators interested in migration history.
What were characteristics of the immigrant experience? How did immigrants and refugees adjust to their new lives in the United States? Inversely, how did American citizens born in the United States react to the increased diversification of their communities, and learn to live with individuals from different ethnic and cultural backgrounds? Minnesota K-12 Academic Standards in Social Studies expect students of all grade levels to consider how immigrants and citizens alike participate in the civic lives of their communities, and to understand the steps that immigrants take to become United States citizens. Incorporating digitized archival material into lesson plans will provide opportunities for students to engage these questions, and prompt young people to begin considering the many types of common experiences that bring together people from all corners of the globe.
In the pages that follow, IHRC staff members have identified digitized images from the collections of the Ukrainian Folk Ballet of the Twin Cities; Immigration and Refugee Services of America; and the International Institute. Founded in 1919, the International Institute was established to provide various services for migrants who recently arrived to the United States. With branches in Minneapolis/Saint Paul, St. Louis, San Francisco, and other major U.S. cities, the International Institute continues to address the needs of the immigrants and refugees who settle in the United States.
The images have been organized thematically in order to initiate student discussion related to Minnesota K-12 Academic Standards and Benchmarks that address the study of migration. By incorporating these archival records into lesson plans, students will be able to think critically about the immigrant experience. Furthermore, working directly with primary sources will enable students to practice and develop research skills that will become increasingly important as they progress in their studies.

The Basics of Home Canning
I never missed the signs of summer coming to a close while I was growing up: shopping for school clothes, getting backpacks and pencils together...and the smell of boiling tomatoes, hot peppers, and pectin permeating the kitchen.
With eleven kids to care for, canning food was not only an event in my household, but a necessity. As soon as we saw the familiar sight of glass mason jars lining the kitchen cupboard, we knew it wouldn’t be long before we were recruited to pick tomatoes, peel peaches, or even pit cherries. Sometimes it seemed mom felt the need to can every living thing in our backyard (with the exception of the dog).
But those long days spent working and canning as a family built stronger relationships, even if it didn’t always build our food storage, like the time a fateful food fight left half our tomatoes on the ground instead of in the bottles.
No matter what produce you plan to stuff away into bottles for the winter, canning can be the ideal way to preserve those fresh foods from your garden or the local market and also provide one last activity to bring your family together before the summer ends.
Canning requires some different utensils that you might not already have in your kitchen. Some of the necessary equipment includes: a boiling-water canner (or a big pot), mason-type jars (different sizes are available, wide-mouth jars are easiest to fill), lids and rings (you can only use the lids once), a jar lifter, and a candy thermometer.
Washing and Sterilizing
This is an important step in the canning process in order to get rid of all bacteria that could contaminate your food. Wash canning jars, new lids, and metal rings in hot, soapy water or the dishwasher, and rinse them thoroughly. To sterilize the jars place them upright in the canner, cover them with hot water, and boil for 10 minutes. Follow the manufacturer’s instructions that come with your lids.
Foods can be processed a number of different ways including: boiling-water, steam-pressure, and freezing. The recipes in this article follow the boiling-water process. To begin the boiling-water method, place a rack on the bottom of the pot to keep jars from touching the canner. Fill the canner half full with hot water and heat to 140º F for raw-packed foods, or 180º F for hot-packed foods. With the jars filled and capped, lower them into the canner with a jar lifter. Add more boiling water, if needed, so the water level is at least one inch above jar tops. Turn the heat to its highest position until water boils vigorously. Set a timer for the minutes required for processing food (according to the recipe).
Add more boiling water, if needed, to keep the water level above the jars. When jars have been boiled for the recommended time, turn off the heat and remove the canner lid. Using a jar lifter, remove the jars and place them on a towel, leaving at least one-inch spaces between the jars during cooling.Start Canning!
If you are trying to can for the first time, it would be best to start with fruit, because most use the boiling-water method. When selecting what fruits to can, select firm, ripe fruit.
Fruits are often canned in light sugar syrups. Depending on your desired taste, the amount of sugar in the syrup varies with fruits. For the recipes here, use a heaping 1/3 cup to 3/4 cup per quart of water. Place the sugar in a quart measuring pitcher and add cold water. Stir until the sugar is dissolved.
These are one of the most successfully canned of all foods. Wash and peel. Halve or quarter and cut out the cores. Boil gently in the syrup liquid for five minutes. Pack the hot pears in hot jars. Add the hot liquid, leaving 1/2-inch headspace. Process for 20 minutes.
Dip peaches in boiling water and remove after a few seconds; slip off the skins. Cut the fruits in half and remove the pits. Place in a pan without crowding, cover with the desired liquid, and bring to a boil. Ladle the hot fruit into hot jars, packing the halves in layers, cut side down. Add the hot liquid, leaving a 1/2-inch headspace. Process for 20 minutes.
TomatoesTomatoes are a canning favorite and can easily be canned using the boiling-water method. To peel tomatoes: Using a small knife, cut a small X in the bottom of the tomatoes; do not cut the flesh. Ease the tomatoes one by one into a pot of boiling water. Leave ripe tomatoes in for about 15 seconds, barely ripe tomatoes for twice as long. Lift them out with a slotted spoon and drop into a bowl of ice water. Pull off the skin with the tip of a knife.
Wash, peel, and cut tomatoes into halves. Put in a pan without crowding, add water to cover, and boil gently for five minutes. Pack the hot tomatoes in hot jars. Add salt to taste. Add the hot cooking liquid, leaving 1/2-inch headspace. Process pints for 40 minutes in canner, quarts for 45 minutes.
Get Yourself into a Jam
Preserving jams can also be a rewarding and easy way to fill your food storage. Jams can be preserved through freezing or canning. For first-timers, frozen jam is generally easier to preserve, but below is also a good canned berry jam recipe for the adventurous.Strawberry Jam (frozen)
2 cups crushed strawberries (1 qt.)
4 cups granulated sugar
1 box fruit pectin
Wash berries, remove stems, and crush. Measure the 2 cups of crushed berries into a large bowl. Measure the sugar into another bowl and then stir it into fruit. Set aside for 10 minutes. Stir occasionally.
Stir 1 box of fruit pectin and 3/4 cup water together in a small saucepan. Bring the mixture to a boil on high heat, stirring constantly. Boil and stir for 1 minute, and remove from the heat. Stir the pectin mixture into the fruit mixture, stirring constantly until the sugar is completely dissolved and no longer grainy.
Pour quickly into clean plastic containers to within 1/2" of the top. Wipe off the top edges of the containers and cover with the lids. Let stand at room temperature for 24 hours to set, and then refrigerate for immediate use or freeze. (Do not double this recipe; make one batch at a time.)
Berry Jam (canned)
Peel, core, and finely grate:
8 ounces tart green apples
- 2 pounds blackberries, blueberries, cranberries, elderberries, or raspberries (stemmed)
- 1 tablespoon orange juice
3 cups sugar
Cook together, crushing one-quarter of the berries that are in the pot, leaving the rest whole (but do not crush raspberries). Boil rapidly, stirring frequently, to the jelling point. This is the point preserves will jell once cooled; a good visual indicator is when, after boiling high and foamy in the pan, the mixture settles, and suddenly its surface is covered with furiously boiling small bubbles. You can also check using a thermometer. Jelling point is 8 to 10 degrees higher than the boiling point of water. Remove from the heat and skim off any foam before ladling into hot jars. Leave 1/4-inch headspace, and process for 10 minutes. | <urn:uuid:710028ea-4dbc-4619-ac69-b371ec871acb> | http://www.ldsliving.com/story/5957-the-basics-of-home-canning |
Winter Around the World:
Whether you observe Yule, Christmas, Sol Invictus, or Hogmanay, the winter season is typically a time of celebration around the world. Traditions vary widely from one country to the next, but one thing they all have in common is the observance of customs around the time of the winter solstice. Here are some ways that residents of different countries observe the season.
Althought Australia is huge geographically, the population sits at under 20 million people. Many of them come from a blend of cultures and ethnic backgrounds, and celebration in December is often a mix of many different elements. Because Australia is in the southern hemisphere, December is part of the warm season. Residents still hhave Christmas trees, Father Christmas, Christmas Carols and gifts which are a familiar Christmas and gifts, as well as being visited by Father Christmas. Because it coincides with school holidays, it's not uncommon for Australians to celebrate the season on vacation away from home.
In China, only about two percent of the population observes Christmas as a religious holiday, although it is gaining in popularity as a commercial event. However, the main winter festival in China is New Year celebration that occurs at the end of January. Recently, it's become known as the Spring Festival, and is a time of gift-giving and feasting. A key aspect of the Chinese New Year is ancestor worship, and painings and portraits are brought out and honored in the family's home.
In Denmark, Christmas Eve dinner is a big cause for celebration. The most anticipated part of the meal is the traditional rice pudding, baked with a single almond inside. Whichever guest gets the almond in his pudding is guaranteed good luck for the coming year. Children leave out glasses of milk for the Juulnisse, which are elves that live in peoples' homes, and for Julemanden, the Danish version of Santa Claus.
The Finns have a tradition of resting and relaxing on Christmas Day. The night before, on Christmas Eve, is really the time of the big feast -- and leftovers are consumed the next day. On December 26, the day of St. Stephen the Martyr, everyone goes out and visits friends and relatives, weather permitting. One fun custom is that of Glogg parties, which involve the drinking of Glogg, a mulled wine made from Madeira, and the eating of lots of baked treats.
Christmas was typically not a huge holiday in Greece, as it is in North America. However, the recognition of St. Nicholas has always been important, because he was the patron saint of sailors, among other things. Hearth fires burn for several days between December 25 and January 6, and a sprig of basil is wrapped around a wooden cross to protect the home from the Killantzaroi, which are negative spirits that only appear during the twelve days after Christmas. Gifts are exchanged on January 1, which is St. Basil's day.
India's Hindu population typically observes this time of year by placing clay oil lamps on the roof in honor of the return of the sun. The country's Christians celebrate by decorating mango and banana trees, and adorning homes with red flowers, such as the poinsettia. Gifts are exchanged with family and friends, and baksheesh, or charity, is given to the poor and needy.
In Italy, there is the legend of La Befana, a kind old witch who travels the earth giving gifts to children. It is said that the three Magi stopped on their way to Bethlehem and asked her for shelter for a night. She rejected them, but later realized she'd been quite rude. However, when she went to call them back, they had gone. Now she travels the world, searching, and delivering gifts to all the children.
In Romania, people still observe an old fertility ritual which probably pre-dates Christianity. A woman bakes a confection called a turta, made of pastry dough and filled with melted sugar and honey. Before baking the cake, as the wife is kneading the dough, she follows her husband outdoors. The man goes from one barren tree to another, threatening to cut each down. Each time, the wife begs him to spare the tree, saying, "Oh no, I am sure this tree will be as heavy with fruit next spring as my fingers are with dough today." The man relents, the wife bakes the turta, and the trees are spared for another year.
In Scotland, the big holiday is that of Hogmanay. On Hogmanay, which is observed on December 31, festivities typically spill over into the first couple of days of January. There's a tradition known as "first-footing", in which the first person to cross a home's threshold brings the residents good luck for the coming year -- as long as the guest is dark-haired and male. The tradition stems from back when a red- or blonde-haired stranger was probably an invading Norseman. | <urn:uuid:22ae9cf3-0877-4766-aa2c-0e14907b8a55> | http://paganwiccan.about.com/od/yulethelongestnight/p/Winter_Customs.htm |
Pricing in the sky
Many policy problems (from road congestion to water and electricity shortages) can be greatly improved through the proper application of a simple concept–pricing. In this USA Today article, Reason's Bob Poole explains how to apply pricing to air traffic control: By charging planes to use the most congested airports and airways, the system would give its customers economic incentives to reschedule flight times or choose less-congested airports without such charges. That easing of demand would provide breathing room to address the looming shortfalls in air-traffic-control capacity. All sorts of new technology can increase this capacity, both cross-country and on the approaches to airport runways. "Synthetic vision" systems can permit pilots to land at socked-in airports at nearly the same rate as in clear weather. So the air-traffic system need not break down just because Chicago has a bad-weather day. Other advanced technologies can reduce the size of the protective bubble needed around planes en route to keep them safely separated. | <urn:uuid:8151331e-4044-4774-a328-c6cf6cc0efd3> | http://reason.org/news/printer/pricing-in-the-sky |

MEMORY WORK (12 minutes)
"You will seek me and find me when you seek me with all your heart" Jeremiah 29:13
Write the verse on the board. Say the verse together as a group several times. Then erase one word. Have the kids say the verse correctly again with the missing word. Then erase another word and say the verse again. Continue erasing words until the kids can say the entire verse without seeing the words.
SCRIPTURE READING AND DISCUSSION (15 minutes)
Today we will learn that prayer is communicating or talking with God. We may not be able to call God on the telephone or send Him a letter, but prayer is just as real as e-mail or newspapers. Why should we pray? Because it makes our relationship with God stronger. Could you imagine trying to have a best friend without communicating with them? Prayer is seeking God and His direction for our lives. Praying also helps keep us out of trouble. Jesus told us to pray, "Watch and pray so that you will not fall into temptation." (Matthew 26:41)
Read James 5:13-16 (The Prayer of Faith)
Have the kids find James 5:13-16 in their Bibles. Ask for a volunteer to read the passage, or if you prefer, read the passage to the children yourself.
1. What is prayer? (Prayer is spiritual communication between ourselves and God.)
2. Can you pray when you are in trouble? (Yes.)
3. Can you pray when you are happy? (Yes.)
4. What is another name for happy prayers? (Praises.)
5. What are some of the examples of why to pray mentioned in James 5:13-16? (When you are in trouble, when you are happy, when you are sick, to show faith, for confession of sin, and to pray for others.)
6. What else can we pray for? (Some examples include: Guidance, Protection, Strength, Wisdom.)
7. Is the prayer of a righteous man powerful? Is it effective? (Yes the Bible tells us in James 5:16b that the prayers of the righteous are both powerful and effective.)

APPLICATION (2 minutes)
Why pray? It's simple, to talk with God and to get His direction for our lives. God is so good and will help us when we are happy, sad, sick or even when we're in trouble. God will give us wisdom, strength and understanding if we only ask Him. In fact God is willing to give us many good things as long as we ask for them in accordance to His Will. God answers our prayers with signs, the Holy Spirit and His Word, the Bible. When we pray our relationship with God grows.

Want to stay on top of all the space news? Follow @universetoday on TwitterSedimentary rock covers 70% of the Earth. Erosion is constantly changing the face of the Earth. Weathering agents…wind, water, and ice…break rock into smaller pieces that flow down waterways until the settle to the bottom permanently. These sediments( pebbles, sand, clay, and gravel) pile up and for new layers. After hundred or thousands of years these rocks become pressed together to form sedimentary rock.
Sedimentary rock can form in two different ways. When layer after layer of sediment forms it puts pressure on the lower layers which then form into a solid piece of rock. The other way is called cementing. Certain minerals in the water interact to form a bond between rocks. This process is similar to making modern cement. Any animal carcasses or organisms that are caught in the layers of sediment will eventually turn into fossils. Sedimentary rock is the source of quite a few of our dinosaur findings.
There are four common types of sedimentary rock: sandstone, limestone, shale, and conglomerate. Each is formed in a different way from different materials. Sandstone is formed when grains of sand are pressed together. Sandstone may be the most common type of rock on the planet. Limestone is formed by the tiny pieces of shell that have been cemented together over the years. Conglomerate rock consists of sand and pebbles that have been cemented together. Shale forms under still waters like those found in bogs or swamps. The mud and clay at the bottom is pressed together to form it.
Sedimentary rock has the following general characteristics:
- it is classified by texture and composition
- it often contains fossils
- occasionally reacts with acid
- has layers that can be flat or curved
- it is usually composed of material that is cemented or pressed together
- a great variety of color
- particle size varies
- there are pores between pieces
- can have cross bedding, worm holes, mud cracks, and raindrop impressions
This is only meant to be a brief introduction to sedimentary rock. There are many more in depth articles and entire books that have been written on the subject. Here is a link to a very interesting introduction to rocks. Here on Universe Today there is a great article on how sedimentary rock show very old signs of life. Astronomy Cast has a good episode on the Earth’s formation. | <urn:uuid:805ab979-777a-4e6d-a60e-66a9c207b774> | http://www.universetoday.com/38537/sedimentary-rock/ |
What can be learned from the post-election crisis in Greece?
The traditional political establishment in Greece buckled under the weight of crippling austerity and a mass people’s movement when the country went to the polls May 6. Now that the voting is over, and attempts to form a government have failed, another election must be held, scheduled for June 17, raising new questions about the way forward for the Greek working class. The crisis deepens as panicking Greeks withdraw their savings from banks on the brink of collapse.
Since the fall of the U.S.-backed military dictatorship that ruled Greece from 1967-1974, two parties, PASOK and New Democracy, have dominated the political scene. However, both parties had their worst showing ever, and combined were only able to muster 32 percent of the vote, down from 77 percent in 2009. Instead, support grew for parties of both the left and the far right. With parliament deadlocked, unable to form a new governing coalition, a new election is pending and there is a distinct possibility of a protracted political crisis and a sharp polarization that provides an opportunity for the working class to decisively assert itself.
Background to the elections
Since the worldwide capitalist economic crisis began in 2007-2008, several countries in the eurozone, which all operate with the common euro currency, have experienced severe debt crises. These national economies are more intimately linked than ever before—which was supposed to be the benefit of the eurozone—so the problems of one immediately threatens the rest.
Germany, the strongest capitalist economy of the eurozone, along with the imperialist U.S., have been working hard to force economic restructuring on the most indebted countries, offering bailouts in exchange for severe cuts to social welfare programs and other austerity measures. They have worked through three main entities: the U.S.-dominated International Monetary Fund, the European Union and the European Central Bank, collectively referred to as the “Troika.” Over the last two years, the Troika has arranged for around €240 billion ($305 billion) in bailout funds for Greece to service its massive debt. In exchange, the Greek ruling class forced through devastating cuts that have led to repeated strikes and militant popular mobilizations.
The Troika has worked hand in hand with the Greek ruling class, which, while claiming to “understand” the opposition of the people, claims that austerity is a difficult but necessary step toward economic revival. The other option, they claim, is complete collapse. It is a story poor and working people across the world are familiar with, including in the United States.
Narrowly winning first place in the elections was New Democracy, a center-right party that was part of the existing government led by Lucas Papademos. An unelected banker, Papademos was appointed to lead the government through its unpopular debt deal. New Democracy campaigned on a platform of supporting the extreme austerity measures imposed by the Troika, and promised only to try to renegotiate some of the more painful terms of the debt deal.
The other pro-austerity party, the misnamed Pan-Hellenic Socialist Movement (PASOK), came in third for the first time in the party’s history. PASOK is led by Evangelos Venizelos, the finance minister under the two previous governments. Venizelos was one of the main architects of the austerity “memorandum” and offered only a pitiful pledge that he would ask the country’s creditors to give them three years, rather than two, to reach absurdly unrealistic economic benchmarks.
Gains on the left
The biggest surprise of the election was the second-place finish of the Coalition of the Radical Left (SYRIZA), with 16.8 percent of the vote. SYRIZA is a collection of small communist tendencies and a larger reformist party that split from the Communist Party of Greece after the fall of the Soviet Union. SYRIZA is led by Alexis Tsipras, a former Communist Youth leader who has received significant international press attention. SYRIZA calls for canceling the bailout deal but keeping Greece inside the eurozone and European Union. This, it says, can be achieved through negotiations with the Troika and through nationalization of the Greek banking sector.
Although there are revolutionary forces within SYRIZA, the dominant line at present is fundamentally social democratic. The “peaceful revolution” they have declared mutes the questions of socialism and working-class power, and raises hopes in a radically reformed capitalism. For example, Tsipras stated in a letter to high-ranking European Union officials, “We must urgently protect the economic and social stability of our country. … It is our duty to re-examine the whole framework of the existing strategy, given that it not only threatens social cohesion and stability in Greece but is a source of instability for the European Union.” While SYRIZA’s leadership wants to reverse austerity, its appeal to “social cohesion and stability” means “stability” under a reformed capitalism.
The second most popular party on the left was the Communist Party of Greece (KKE), which registered a modest increase of 1 percent from their previous election result, ending up with 8.5 percent. This was below the 10-12 percent that most opinion polls predicted. The KKE put forward a platform calling for the socialization of the means of production under a “working class-people’s power” government. Of the left groups in parliament, the Communist Party is the only one to call for Greece to leave the European Union, a bloc of the major imperialist and peripheral capitalist states of Europe.
The KKE has played a major role in the massive fight-back movement waged by the Greek working class and especially in its advocacy for general strikes. It intervenes through mass organizations like the All-Workers Militant Front (PAME) in the labor movement, the Greek Women’s Federation and the Students Struggle Front, among others.
The lowest scoring of the three left parties was Democratic Left, a split to the right from SYRIZA formed in 2010. It only received 6.1 percent of the vote, but its leader Fotis Kouvelis is often ranked as the most popular politician in Greece by opinion polls. Democratic Left rejects the memorandum, but makes sure to balance its criticism of austerity with pledges of absolute loyalty to the eurozone.
Major gains for far right and fascists
Far-right forces experienced major gains in the election as well. The semi-fascist Popular Orthodox Rally suffered as punishment for its participation in the previous government, but new forces emerged. Independent Greeks, a split from New Democracy, came in fourth with 10.6 percent. The party rejects the austerity memorandum on nationalistic grounds and relies on anti-German and anti-Turkish demagogy in place of a specific political program.
The story that has perhaps gotten the most foreign press attention is the entrance of the neo-Nazi Golden Dawn party into parliament with 7 percent of the vote, more than 20 times their score in 2009. Its logo is an ancient Greek symbol similar to a swastika, and until recently Adolf Hitler’s manifesto Mein Kampf was displayed prominently at the party’s headquarters.
Golden Dawn campaigned on a platform of expelling all immigrants from Greece and national chauvinist opposition to the Troika. While some voters were attracted to its racist rhetoric and acts of violence against immigrants, Golden Dawn bought the loyalty of others by operating food banks during a time of growing hunger.
The fascists’ success is a serious threat to the working class and all democratic forces in Greece. While its 7 percent may appear small, it is precisely under these polarized economic and political conditions, when the capitalist class cannot achieve stable rule through democratic means, that fascism has historically grown and taken power.
The main bourgeois parties cynically used the threat of Golden Dawn to present the false dilemma of austerity or a descent into fascism. But in reality, these mainstream parties’ promotion of anti-immigrant racism gave Golden Dawn political space to grow. Moreover, if it appeared that the working class could potentially become the ruling power in Greece, the bourgeoisie could accept, if not turn to, a fascist coup.
That the Greek ruling class has operated under fascist military rule before makes such a scenario all the more plausible.
It is up to the revolutionary left and the working class to develop a program and plan of action to smash fascism politically and in the streets.
A ‘government of the left’?
A central component of the SYRIZA campaign was its appeal for the formation of a “government of the left,” encompassing all the left forces opposed to the Troika. The formation of such a government was impossible given the election results and highly implausible given Greece’s undemocratic electoral laws governing coalitions. But SYRIZA’s call for a government of the left clearly resonated with much of the working class and contributed to its success. If SYRIZA were to emerge in first place in the June election, as presently projected, the left could achieve such a majority.
SYRIZA leader Tsipras and other social-democratic proponents of a government of the left argue that it would be able to cancel the memorandum, reverse the wave of austerity measures, potentially nationalize the banks and rebuild the Greek economy in a way that strengthens the working class. SYRIZA makes the case that the European ruling class would never let Greece default and exit the eurozone because of the economic havoc this would create in other heavily indebted states like Spain and Italy. In short, Tsipras pledges to reverse the balance of forces inside the eurozone; instead of the Troika forcing Greece into deeper austerity, Greece would leverage its power against the Troika.
While the Troika obviously wants to avoid a complete Greek default (lenders have already accepted a 53.5 percent write-down on the debt), they have had the last two years to prepare for this eventuality. The centerpiece of the European ruling class’ preparations is the European Financial Stability Facility, a $976 billion bailout fund, meant to act as a “firewall” to counter the immediate effects of a Greek bankruptcy. With this in place, there is a small but growing tendency of capitalist financiers who believe that if Greece were expelled, the eurozone would “end up stronger once the dust had settled.”
Tsipras insists that Greece can out-negotiate the international capitalists, rather than calling for the socialist reorganization of society. He raises unrealistic expectations among the oppressed in electoral and bourgeois political gamesmanship, rather than raising the possibility of a new class power.
Why revolution is necessary
By contrast, the KKE has called the “government of the left” idea a false hope that will lead to disillusionment. The KKE rejects possible participation in a left government, insisting that such a government will leave the capitalist state and the for-profit economic system intact, keep Greece bound to the imperialist institutions of the EU and NATO, and thus cannot resolve the central contradictions at the heart of the political crisis.
More broadly, they explain that the social-democratic program, which arose in the post-war period of capitalist expansion, cannot be achieved in the context of protracted capitalist crisis and neoliberal financial control. They have called the SYRIZA plan opportunist, betraying the long-term interests and political clarity of the working class in exchange for short-term gains for particular leftist parties.
This raises the age-old but still pivotal question of reform and revolution: Does the working class have the capacity to come to power, and how so? Can the capitalist system be reformed to resolve the exploitation at its center? How far can revolutionary organizations go at this time?
Several organizations in Greece—including the KKE—have made the case that the political crisis of the bourgeois class has matured to the point of a revolutionary situation, opening the possibility for the transfer of power to the working class in alliance with middle-class strata.
Revolutionaries, of course, fight for reforms that improve the conditions of the working class and facilitate the political struggle against the ruling class. But a central responsibility is to assess whether the conditions for revolution are approaching, to hasten their development and prepare for such an opportunity.
The basic contradiction in capitalist society is that the productive process is socialized, involving millions of workers, while ownership is private, concentrated in a tiny ruling class. The capitalists control the means of production and distribution, as well as countless financial mechanisms, to squeeze profits out of workers and maintain their political and economic power. The capitalist state (the police, military and courts) allows them to safeguard this system with force, while the government provides for its administration.
A change in administration, like the ascent of a government of the left, will not alter the fundamental underlying character of the state. This can only be achieved by the overthrow of the capitalist state and its replacement by a worker’s state based on independent organs of working-class power—a socialist revolution.
Elections and the revolutionary process
Some communist tendencies support the formation of a government of the left for this reason—not because it would solve the crisis, but because it would further polarize the country and hasten the development of a revolutionary situation.
There can be no doubt that the formation of a SYRIZA-KKE-Democratic Left coalition would cause considerable panic among the Greek and European ruling class, and new bouts of intense class struggle.
History has shown that revolutions can take many paths and tactical turns. In Venezuela, the election of President Hugo Chávez, a socialist presiding over a fundamentally capitalist state, undoubtedly gave a boost to the class struggle and the regroupment of revolutionary forces in the country.
In Nepal, Maoists waged a triumphant revolutionary war against the feudal king that resulted in a negotiated peace and the Maoists’ subsequent election to lead a bourgeois government. Their decision to dissolve their armed forces remains the subject of considerable debate among revolutionaries. Neither country, despite heroic advances, has established socialism.
But for a Greek left government to be a vehicle of revolution, instead of demobilization, demoralization and disillusionment, a left-wing government would need to have clear programmatic unity around the socialization of the means of production, centralized planning, workers’ political power, and so on. It would need to organize the people to take on the police and the military that their own left-unity government would be associated with and nominally leading.
Otherwise, when a revolutionary situation emerged it would only disorient the movement and contribute to the persistence of reformist illusions.
SYRIZA has been silent or worse on these critical questions. In the run-up to the elections, Tsipras said: “A government of the left is in need of industrialists and investors. It needs a healthy business climate.” In other words, his version of a government of the left would not challenge the capitalists’ right to exploit labor.
The capitalist establishment has reciprocated, and the Federation of Hellenic Enterprises (SEV), the Greek equivalent of the U.S. Chamber of Commerce, has called for the formation of a national unity government including SYRIZA.
Tsipras called the election results a “peaceful revolution,” a slogan that misleadingly suggests the electoral realm, rather than continued mass struggle, can provide a way out of the crisis for working people.
The revolutionary crisis and dual power
While support for SYRIZA is likely to increase in the coming election, it is doubtful the new election will produce a clear winner or workable coalition. In the face of the increased likelihood of exiting the eurozone, which would deepen the economic and political crisis, the class struggle will intensify.
With the bourgeoisie so thoroughly discredited, and the Greek masses so clearly calling for an alternative way, the revolutionary left has an opportunity to offer a program that provides not only short-term relief, but also a longer-term vision of a new economic and political system. The question is how to mobilize the working class and broadly unite the revolutionary forces in a struggle to achieve this.
Historically, a key phase in any revolutionary crisis is that of dual power. By organizing what is essentially a second, rival state built on organs of mass struggle, revolutionaries can show concretely what working-class or people’s power looks like and offers. In the Russian Revolution, this took the form of councils of workers and soldiers (called soviets). In China, the Red Army itself functioned as a government in the areas that it liberated. Revolutionaries have also convened constituent assemblies—to rewrite the constitution—as a way to articulate, and establish the legitimacy of, a new political vision.
Clearly, there are millions in Greece who are still holding out hope that the existing capitalist government and state, perhaps with left-wing leadership, can deliver the goods. To this end, a sophisticated political struggle, backed by a concrete plan of action, must be waged against Tsipras and the social-democratic fantasies he projects. In his “April Theses,” designed to guide the Bolsheviks through Russia’s revolutionary crisis, Lenin called for “patient, systematic, and persistent explanation … especially adapted to the practical needs of the masses.”
Can the struggle in the streets break the deadlock in parliament? Will alternatives to bourgeois state power be built? The Greek working class has found itself on the frontline of the international struggle against capitalism, and the answers to these questions will resonate around the world.
For revolutionaries in the United States, our main role is not to endorse this or that organization and its tactics from afar. Our chief responsibilities are 1) to explain that the Greek crisis is a result of the contradictions of capitalism, not reckless social spending, 2) to defend the unfolding Greek revolution, especially as it could escalate and be slanderously attacked in the imperialist media and even militarily assaulted by U.S.-NATO forces, and 3) to study and learn from the complex revolutionary process that our brothers and sisters are trying to navigate.
While their process is far more advanced than our own, their struggle is ours—and we have much to learn from it. | <urn:uuid:0bb2acb2-bd9e-4c58-b2aa-1fc1d3444f08> | http://crimsonsatellite.wordpress.com/2012/05/17/reform-and-revolution-in-greece/ |
Genital/ perigenital infection caused by the yeast-like fungus Candida albicans or occasionally by other species of Candida. Vulvovaginitis due to Candida presents with an erythema of the vaginal mucous membrane and the vulval skin, itching, soreness, and with a thick, creamy-white discharge. There may be spread on to the perineum and into the groins. In Candida balanitis, tiny papules develop on the glans penis, evolve as white pustules or vesicles and rupture, leaving a peeling edge. Involvement of groins sometimes coexists. Perianal candidiasis presents with erythema, soreness and irritation, and subsequent spread along the natal cleft is common.
