description: Purpose: Suboptimal bowel preparation can result in decreased neoplasia detection, shortened surveillance intervals, and increased costs. We assessed bowel preparation recommendations and the relationship to self-reported proportion of suboptimal bowel preparations in practice; and evaluated the impact of suboptimal bowel preparation on colonoscopy surveillance practices. A random sample of a national organization of gastroenterologists in the U.S. was surveyed.
Methods: Demographic and practice characteristics, bowel preparation regimens, and proportion of suboptimal bowel preparations in practice were ascertained. Recommended follow-up colonoscopy intervals were evaluated for optimal and suboptimal bowel preparation and select clinical scenarios.
Results: We identified 6,777 physicians, of which 1,354 were randomly selected; 999 were eligible, and 288 completed the survey. Higher proportion of suboptimal bowel preparations/week (≥10 %) was associated with hospital/university practice, teaching hospital affiliation, greater than 25 % Medicaid insured patients, recommendation of PEG alone and sulfate-free. Those reporting greater than 25 % Medicare and privately insured patients, split dose recommendation, and use of MoviPrep® were associated with a less than 10 % suboptimal bowel preparations/week. Shorter surveillance intervals for three clinical scenarios were reported for suboptimal preparations and were shortest among participants in the Northeast who more often recommended early follow-up for normal findings and small adenomas. Those who recommended 4-l PEG alone more often advised less than 1 year surveillance interval for a large adenoma.
Conclusions: Our study demonstrates significantly shortened surveillance interval recommendations for suboptimal bowel preparation and that these interval recommendations vary regionally in the United States. Findings suggest an interrelationship between dietary restriction, purgative type, and practice and patient characteristics that warrant additional research.

description: This research study investigated the experiences of two parents whose child was diagnosed with severe-to-profound hearing loss due to the congenital inner ear abnormalities of cochlear nerve deficiency and bilateral common cavity deformity. Despite her diagnoses, the child received a cochlear implant in her second year of life. Parents’ experiences regarding their child’s hearing loss were explored using a narrative approach to qualitative interviewing. Each parent was interviewed separately and the resulting transcripts were analyzed both separately and together as a dyad. Principles of qualitative description were followed in describing results to privilege the voice of the parents. The parents’ experiences are presented first as a chronologically-organized joint narrative; themes that emerged from one or both interviews are then discussed. Results of this study add valuable insight to the research literature regarding cochlear implantation outcomes for children with cochlear nerve deficiency. This study also supports the value of dyadic analysis in qualitative research, particularly for the fields of speech-language pathology and audiology. Finally, the parents’ experiences depicted in this study draw attention to issues that have important clinical implications for audiologists and other professionals who counsel families of children with hearing loss.

description: The conservation value of captive-bred lions is seriously questioned by most conservation minded people - to such an extent that they refuse to admit that these lions can make an enormous contribution towards the enhancement of the lion in the wild. Reasons offered range from alleged genetic contamination to captive-bred lions' alleged inability to adapt to conditions in the wild, including their alleged inability to acquire the social skills to function successfully in a pride. These allegations seem to be inspired by either a lack of understanding of the realities driving the decline of lion populations in Africa or a misunderstanding of the objectives and intentions of the captive-bred lion industry of South Africa or both. Notwithstanding unethical conduct and practices by lion farmers uncovered from time to time the industry at large is functioning on the principle of sustainable use. It exploits, by consumptive as well as non-consumptive use, a very esteemed and iconic game species economically, thereby generating a livelihood for self and for local communities. However, the industry is acutely aware of its responsibility to contribute to the survival and welfare of the lions in the wild. This responsibility is operationalised through various projects, including scientific research, financial support for lion conservation and, ultimately, there-establishment of lions in areas in Africa where they have become extinct.

Προκειμένου, λοιπόν, να υποστηριχθούν αυτές οι λειτουργίες, απαιτούνται γρήγορες, ανθεκτικές και αξιόπιστες συνδέσεις επικοινωνίας. Με την έλευση του Δικτύου Κινητής Τηλεφωνίας Πέμπτης Γενιάς (5G) (και του προκατόχου του 4G LTE Cellular Network) τα UAV θα μπορούν να επεκτείνουν τις δυνατότητές τους στις πραγματικές εφαρμογές. Από αυτή την άποψη, στόχο της παρούσας εργασίας αποτελεί η μελέτη ενσωμάτωσης και να λειτουργίας του δικτύου κινητής τηλεφωνίας 5G στα UAV ως το κύριο κανάλι επικοινωνίας για το C2 (Command &Control) και το ωφέλιμο φορτίο (Payload). Επομένως, τα UAV θα μπορούν να λειτουργούν ελεγχόμενα BVLOS, εντός των περιορισμών του δικτύου κινητής τηλεφωνίας, διασφαλίζοντας απρόσκοπτη και αξιόπιστη επικοινωνία. Αυτή η εφαρμογή πρέπει πάντα να γίνεται σε σχέση με τις τυποποιημένες τυποποιήσεις της 3GPP (3rd Generation Partnership Project). Στο πλαίσιο, λοιπόν, της ερευνάς αυτής παρουσιάζεται το απαραίτητο θεωρητικό υπόβαθρο για την ανάλυσης του μοντέλου διάδοσης των μικροκυμάτων, οι επικοινωνιακές απαιτήσεις που θέτει η 3GPP καθώς και έτερες μελέτες μετά συμπερασμάτων τους στον εν λόγω τομέα. Ιδιαίτερη έμφαση δε, δίνεται στις προκλήσεις που έχουν προκύψει στις έρευνες αυτές καθώς και τρόπους για την αντιμετώπισή τους για την επαύξηση της ποιότητας των υπηρεσιών των UAV από το τηλεπικοινωνιακό δίκτυο. Προς αυτή την κατεύθυνση υλοποιείται ένα 4G LTE/5G UAV ώστε να μελετηθεί και να αναλυθεί αν ένα κυψελοειδές δικτυωμένο drone (με την υπάρχουσα υποδομή) είναι σε θέση να εκπληρώσει τις απαιτήσεις στις σημερινές και μελλοντικές πολιτικές εφαρμογές.

description: We show how the magneto-phonon resonance, particularly pronounced in sp2 carbon allotropes, can be used as a tool to probe the band structure of multilayer graphene specimens. Even when electronic excitations cannot be directly observed, their coupling to the E2g phonon leads to pronounced oscillations of the phonon feature observed through Raman scattering experiments with multiple periods and amplitudes detemined by the electronic excitation spectrum. Such experiment and analysis have been performed up to 28T on an exfoliated 4-layer graphene specimen deposited on SiO2, and the observed oscillations correspond to the specific AB stacked 4-layer graphene electronic excitation spectrum.

Locking Local Oscillator Phase to the Atomic Phase via Weak Measurement

description: We propose a new method to reduce the frequency noise of a Local Oscillator (LO) to the level of white phase noise by maintaining (not destroying by projective measurement) the coherence of the ensemble pseudo-spin of atoms over many measurement cycles. This scheme uses weak measurement to monitor the phase in Ramsey method and repeat the cycle without initialization of phase and we call, "atomic phase lock (APL)" in this paper. APL will achieve white phase noise as long as the noise accumulated during dead time and the decoherence are smaller than the measurement noise. A numerical simulation confirms that with APL, Allan deviation is averaged down at a maximum rate that is proportional to the inverse of total measurement time, tau^-1. In contrast, the current atomic clocks that use projection measurement suppress the noise only down to the level of white frequency, in which case Allan deviation scales as tau^-1/2. Faraday rotation is one of the possible ways to realize weak measurement for APL. We evaluate the strength of Faraday rotation with 171Yb+ ions trapped in a linear rf-trap and discuss the performance of APL. The main source of the decoherence is a spontaneous emission induced by the probe beam for Faraday rotation measurement. One can repeat the Faraday rotation measurement until the decoherence become comparable to the SNR of measurement. We estimate this number of cycles to be ~100 cycles for a realistic experimental parameter.

description: Although this contribution is not intended to be a comprehensive perspective on current knowledge of soil respiration, a brief overview of some pertinent research on global patterns of soil respiration is presented first to establish a context for the subsequent more focused discussion of the role of microbial communities in soil carbon budgets and net respiratory CO2 flux to the atmosphere. Major reviews, and relevant broad research studies of current knowledge about regional and global respiratory flux patterns, are available from other sources. These include reviews of terrestrial respiration in broad geographical regions (e.g. [Luo and Zhou, 2006] , [Peng and Apps, 2000] , [Raich and Schlesinger, 1992] , [Schimel, 1995] and [Schlesinger, 1997] ); in particular geographic regimes and biomes (e.g. [Anderson, 2010a] , [Bekku et al., 2003] , [Bond-Lamberty and Thomson, 2010] and [Townsend et al., 1992] ); and in relation to soil decomposition processes (e.g. [Adl, 2003] and [Tate, 1995] ). Calculated on a global scale, soil respiration releases carbon at a rate that is more than one order of magnitude larger than anthropogenic emissions (Luo and Zhou 2006, p. 24). With increasing evidence of global climate change, including increasing global temperature and likely major changes in patterns of precipitation, effects on soil microbial communities are likely to be significant, especially at higher latitudes where thawing of the permafrost may release substantial quantities of stored-up carbon compounds, thus increasing microbial respiration and efflux of CO2 to the atmosphere. In the final sections, discussion focuses on emerging evidence of the effects of climate change, especially changing precipitation patterns and soil moisture, on the dynamics of microbial communities and respiratory CO2 emissions. Some of the prospects and challenges for future inquiry on the role of soil microbial communities in terrestrial carbon budgets and CO2 efflux are discussed in relation to emerging research themes and new methodological approaches.

description: In the current debate over the constitutionality of voter identification laws, both the Supreme Court and defenders of such laws have justified them, in part, as counteracting a widespread fear of vote fraud that leads citizens to disengage from the democracy. Because actual evidence of voter impersonation fraud is rare and difficult to come by if fraud is successful, reliance on public opinion as to the prevalence of fraud threatens to allow courts to evade the difficult task of balancing the actual constitutional risks involved. In this Essay we employ a unique survey to evaluate the causes and effects of public opinion regarding vote fraud. We find that perceptions of fraud have no relationship to an individual's likelihood of turning out to vote. We also find that voters who were subject to stricter identification requirements believe fraud is just as widespread as do voters subject to less restrictive identification requirements.

description: We use the Chandra unresolved X-ray emission spectrum from a 12'-28' (2.8-6.4 kpc) annular region of the Andromeda galaxy to constrain the radiative decay of sterile neutrino warm dark matter. By excising the most baryon-dominated, central 2.8 kpc of the galaxy, we reduce the uncertainties in our estimate of the dark matter mass within the field of view and improve the signal-to-noise ratio of prospective sterile neutrino decay signatures relative to hot gas and unresolved stellar emission. Our findings impose the most stringent limit on the sterile neutrino mass to date in the context of the Dodelson-Widrow model, m_s < 2.2 keV (95% C.L.). Our results also constrain alternative sterile neutrino production scenarios at very small active-sterile neutrino mixing angles.

description: The US Congress and President unanimously agreed on a national mammalian symbol with the National Bison Legacy Act of 2016. The law is entirely symbolic and could mean nothing to socially and ecologically rewild bison which might have totaled 30-60 million: the last clause of the bill reads "Nothing in this act or the adoption of the North American bison as the national mammal of the United States shall be construed or used as a reason to alter, change, modify, or otherwise affect any plan, policy, management decision, regulation, or other action by the federal government." Approximately 500,000 bison (20,000 plains and 10,000 wood bison) live in 62 conservation herds in the Great Plains and boreal forests of North America. Perhaps 15,000 bison are free-ranging and able to function ecologically. Relic extant populations persisted since near extirpation during the 1800s in Yellowstone National Park (4,900), and were restored on other public lands. Most numbers, 90 percent, were introduced to fenced private and tribal lands, bred for meat, husbanded as novelties and exhibits, or fostered for ecological and social considerations. The rewilding dream is limited by human populations and infrastructures, land uses, fragmented suitable landscapes, and attitudes that are incompatible with free-roaming wild herds of 1/2 to one ton ungulates. Mangers with governments, tribes, organizations, and private lands seek uncertain futures for bison considering legislation, land use alternatives, economics, social perspectives, dreams, and actions that not all can agree. Must we accept symbolic management of relics or ecologically rewild our dreams.

description: We solve the thin-slit diffraction problem for two-dimensional lattice waves. More precisely, for the discrete Helmholtz equation on the semi-infinite square lattice with data prescribed on the left boundary (the aperture), we use lattice Green's functions and a discrete Sommerfeld outgoing radiation condition to derive the exact solution everywhere in the lattice. The solution is a discrete convolution that can be evaluated in closed form for the wave number $k=2$. For other wave numbers, we give a recursive algorithm for computing the convolution kernel.

Greenhouse gases embodied in international trade : an input-output analysis for Canada : 2002
Creators: name: Tran, Julie
Publisher: name: University of British Columbia
Year: 2011

description: Both climate change and actions to fight it are occurring against rapidly expanding international trade flows, which increasingly lead to the separation of production and consumption patterns. Through the trade of goods in a globally interdependent world, the consumption in each country is linked to greenhouse gases (GHG) emissions in other countries because GHGs are emitted throughout the supply chain involved in producing those goods; a phenomenon referred to as ‘embodied GHG’. In this research, taking a consumption-based approach and using an environmental input-output analysis, I explore the amount of GHGs embodied in Canada’s imports and export for the year 2002 and determine that Canada has a negative balance of embodied emissions in trade (BEET). This implies that the GHGs emitted in connection with the production of exported goods surpass those emitted in connection with the production of imported goods. In light of Canada’s large trade surplus in 2002, my finding support the hypothesis that there may be an inherent conflict between a national GHG reduction target for domestic emissions and the aims of improving trade balances or maintaining trade surpluses. While my negative BEET result holds under different model specifications (i.e., single-country or multi-country model), I also show that it is highly dependent on the exchange rate used to convert the value of Canadian imports from the U.S. into the U.S. currency. Thus, my results demonstrate the weakness of using monetary flows of merchandise trade when trying to estimate physical quantities, in this case, the amount of GHGs embodied in the traded goods. Finally, I also discuss some of the key intersections between climate and trade policies, with a particular focus on climate policies that attempt to link the consumption of goods in a country with the amount of GHGs emitted during their production, whether in that country or elsewhere.

description: The Blanco Cosmology Survey (BCS) is a 60 night imaging survey of $\sim$80 deg$^2$ of the southern sky located in two fields: ($α$,$δ$)= (5 hr, $-55^{\circ}$) and (23 hr, $-55^{\circ}$). The survey was carried out between 2005 and 2008 in $griz$ bands with the Mosaic2 imager on the Blanco 4m telescope. The primary aim of the BCS survey is to provide the data required to optically confirm and measure photometric redshifts for Sunyaev-Zel'dovich effect selected galaxy clusters from the South Pole Telescope and the Atacama Cosmology Telescope. We process and calibrate the BCS data, carrying out PSF corrected model fitting photometry for all detected objects. The median 10$σ$ galaxy (point source) depths over the survey in $griz$ are approximately 23.3 (23.9), 23.4 (24.0), 23.0 (23.6) and 21.3 (22.1), respectively. The astrometric accuracy relative to the USNO-B survey is $\sim45$ milli-arcsec. We calibrate our absolute photometry using the stellar locus in $grizJ$ bands, and thus our absolute photometric scale derives from 2MASS which has $\sim2$% accuracy. The scatter of stars about the stellar locus indicates a systematics floor in the relative stellar photometric scatter in $griz$ that is $\sim$1.9%, $\sim$2.2%, $\sim$2.7% and$\sim$2.7%, respectively. A simple cut in the AstrOmatic star-galaxy classifier {\tt spread\_model} produces a star sample with good spatial uniformity. We use the resulting photometric catalogs to calibrate photometric redshifts for the survey and demonstrate scatter $δz/(1+z)=0.054$ with an outlier fraction $η<5$% to $z\sim1$. We highlight some selected science results to date and provide a full description of the released data products.

description: (abridged) We used the wide-field IFU spectrograph PMAS/PPAK at the 3.5m telescope of Calar Alto Observatory to observe six nearby spiral galaxies that hosted SNe Ia. Spatially resolved 2D maps of the properties of the ionized gas and the stellar populations were derived. Five of the observed galaxies have an ongoing star formation rate of 1-5 M_sun/yr and mean stellar population ages ~5 Gyr. The sixth galaxy shows no star formation and has an about 12 Gyr old stellar population. All galaxies have stellar masses larger than 2E+10 M_sun and metallicities above solar. Four galaxies show negative radial metallicity gradients of the ionized gas up to -0.058 dex/kpc and one has nearly uniform metallicity with a possible shallow positive slope. The stellar components show shallower negative metallicity gradients up to -0.03 dex/kpc. We find no clear correlation between the properties of the galaxy and those of the supernovae, which may be because of the small ranges spanned by the galaxy parameters. However, we note that the Hubble residuals are on average positive while negative Hubble residuals are expected for SNe Ia in massive hosts such as the galaxies in our sample. In conclusion, IFU spectroscopy on 4-m telescopes is a viable technique for studying host galaxies of nearby SNe Ia. It allows one to correlate the supernova properties with the properties of their host galaxies at the projected positions of the supernovae. Our current sample of six galaxies is too small to draw conclusions about the SN Ia progenitors or correlations with the galaxy properties, but the ongoing CALIFA IFU survey will provide a solid basis to exploit this technique more and improve our understanding of SNe Ia as cosmological standard candles.

description: International trade in rhino horn was banned in the 1970's and this ban has had the same effect as the prohibition of alcohol did in the US by creating a black market. Banning trade has only contributed to increasing poaching as also evidenced by South Africa's ban of domestic trade in rhino horn being followed by a spike in poaching. Legalising trade will take away control of trade from black markets and let regulated markets take over thus crippling criminal syndicates and curbing rhino poaching. The ban on international trade of rhino horn and all other interventions, including anti-poaching units and awareness campaigns, have failed to effectively protect rhinos. Sustainable utilisation of rhinos is the only logical option left to save rhinos. Sustainable utilisation requires legalizing trade and has been proven in the past to be effective as seen with animals such as ostriches, crocodiles and others. Sustainable use of South America's vicuñahas resulted in the animal being saved from extinction while contributing to conservation and alleviating poverty, the same can be achieved with rhinos through legalisation of trade. For this reason rhino horn can be sustainably utilised by harvesting it regularly through dehorning without killing the animal. When harvesting you get about 30 to 60 kilograms of rhino horn from a single rhino that is kept alive over a period of time. Through poaching or pseudo hunting you only get about 1-3kg and at times even 6kg from a full grown adult and the rhino is killed.

Hobbes and the Congo: Frames, Local Violence, and International Intervention

description: Why do international peacebuilders fail to address the local causes of peace process failures? The existing explanations of peacebuilding failures, which focus on constraints and vested interests, do not explain the international neglect of local conflict. In this article, I show how discursive frames shape international intervention and preclude international action on local violence. Drawing on more than 330 interviews, multi-sited ethnography, and document analysis, I develop a case study of the Democratic Republic of Congo's transition from war to peace and democracy (2003-2006). I demonstrate that local agendas played a decisive role in sustaining local, national, and regional violence. However, a postconflict peacebuilding frame shaped the international understanding of violence and intervention in such a way that local conflict resolution appeared irrelevant and illegitimate. This frame included four key elements: international actors labeled the Congo a "postconflict" situation; they believed that violence there was innate and therefore acceptable even in peacetime; they conceptualized international intervention as exclusively concerned with the national and international realms; and they saw holding elections, as opposed to local conflict resolution, as a workable, appropriate, and effective tool for state- and peacebuilding. This frame authorized and justified specific practices and policies while precluding others, notably local conflict resolution, ultimately dooming the peacebuilding efforts. In conclusion, I contend that analyzing discursive frames is a fruitful approach to the puzzle of international peacebuilding failures beyond the Congo.

Holographic dark matter and dark energy with second order invariants

description: One of the main goals of modern cosmology remains to summon up a self consistent policy, able to explain, in the framework of the Einstein's theory, the cosmic speed up and the presence of Dark Matter in the Universe. Accordingly to the Holographic principle, which postulates the existence of a minimal size of a physical region, we argue, in this paper, that if this size exists for the Universe and it is accrued from the independent geometrical second order invariants, it would be possible to ensure a surprising source for Dark Matter and a viable candidate for explaining the late acceleration of the Universe. Along the work, we develop low redshift tests, such as Supernovae Ia and kinematical analysis complied by the use of Cosmography and we compare the outcomes with higher redshift tests, such as CMB peak and anisotropy of the cosmic power spectrum. All the results indicate that the models presented here can be interpreted as unified models that are capable to describe both the dark matter and the dark energy.

description: We general relativistically calculate the frequency of fundamental torsional oscillations of neutron star crusts, where we focus on the crystalline properties obtained from macroscopic nuclear models in a way depending on the equation of state of nuclear matter. We find that the calculated frequency is sensitive to the density dependence of the symmetry energy, but almost independent of the incompressibility of symmetric nuclear matter. By identifying the lowest-frequency quasi-periodic oscillation in giant flares observed from soft gamma-ray repeaters as the fundamental torsional mode and allowing for the dependence of the calculated frequency on stellar models, we provide a lower limit of the density derivative of the symmetry energy as $L\simeq 50$ MeV.

description: Background: Numerous studies have suggested that emergency medical services (EMS) providers are ill-prepared in the areas of training and equipment for response to events due to weapons of mass destruction (WMD) and other public health emergencies (epidemics, etc.).
Methods: A nationally representative sample of basic and paramedic EMS providers in the United States was surveyed to assess whether they had received training in WMD and/or public health emergencies as part of their initial provider training and as continuing medical education within the past 24 months. Providers also were surveyed as to whether their primary EMS agency had the necessary specialty equipment to respond to these specific events.
Results: More than half of EMS providers had some training in WMD response. Hands-on training was associated with EMS provider comfort in responding to chemical, biological, and/or radiological events and public health emergencies (odds ratio (OR) = 3.2,95% confidence interval (CI) 3.1, 3.3). Only 18.1% of providers surveyed indicated that their agencies had the necessary equipment to respond to a WMD event. Emergency medical service providers who only received WMD training reported higher comfort levels than those who had equipment, but no training.
Conclusions: Lack of training and education as well as the lack of necessary equipment to respond to WMD events is associated with decreased comfort among emergency medical services providers in responding to chemical, biological, and/or radiological incidents. Better training and access to appropriate equipment may increase provider comfort in responding to these types of incidents
The role of tourism in the sustainable use of wildlife

description: The game farming industry has experienced rapid growth over the past 20 years. We have seen an increase in the number of game farms, job opportunities, breeding programmes, auctions, hunting and number and value of game in general. South Africa has also, over the same period, experienced a significant increase in the number of tourist arrivals to the country, with approximately 10 million tourists visiting our shores per annum. Most of these tourists come to experience South Africa's nature and wildlife in one form or another, which links back to the products offered by the game farming industry. One of the key issues facing the future of game farms as well as the tourism industry in general, is sustainability. The complexity of sustainability lies in the fact that it has to do with not only financial, but also environmental, social and economic sustainability. In other words, how can we as a game farming industry achieve sustainability in all its forms and levels? The purpose of this presentation is to highlight the important role of tourism in game farm management. Currently one of the biggest generators of revenue for game farms is hunting, whilst tourism has played a less important role. One of the reasons for this is ignorance in terms of how tourism and tourism trends can be used as a source of revenue, since game farms lent themselves to different forms of tourism activities, which should be exploited. As in the case of agriculture, it would be beneficial for game farm managers to diversify their products and also their sources of revenue. The paper will highlight the change in sources of income for game farms over the past 20 years and in addition, the paper will also highlight threats to not only the game farms, but the industry as a whole, and possible solutions to managing these threats.
