Title:	ASSESSMENT OF ACADEMIC DISHONESTY IN A COMMUNITY COLLEGE: AN APPLICATION OF THE RANDOMIZED RESPONSE TECHNIQUE

Abstract:	The purpose of this study was to estimate the extent to which cheating behaviors occur among mathematic students at a community college. The study was conducted at the Kendall Campus of Miami-Dade Community College, during the Winter term, 1992.

A pilot study compared the reported rate of cheating among 47 upper-level mathematics students and 46 mathematically underprepared students using direct questioning and the randomized response technique. The forced alternative randomized response technique was employed to assess attitudes held about cheating and to estimate reported rates of cheating among 298 community college mathematics students. Factors related to cheating such as age, gender, birthplace, religiosity, membership in a religious organization, involvement in extracurricular activities, and self-perception of honesty were also explored. Hypotheses were tested using chi square tests of independence, frequency distributions, z-tests for significance, and a randomized response formula.

The estimated percent of mathematics students who report that they cheated while attending M-DCC was 31%. The forced alternative randomized response technique was found to have utility in a group setting. Direct questioning underestimated the reported rate of cheating; however, differences were not statistically significant.

Upper-level mathematics students reported they cheated at the same rate as mathematically underprepared students. Calculus students were less likely to report someone for cheating. Males, students under 25 years old, and students born abroad also agreed that reporting cheating was worse than actually cheating. Students who reported they had cheated were more likely to be formally affiliated with a religious organization. Reported rate of cheating was inversely related to self-perception of honesty. Students over 25 years of age were the least likely to cheat.

Recommendations included: further investigation of the randomized response technique, particularly where the actual incidence of the sensitive behavior can be determined and compared with the estimated proportions; a comparison of cheating behaviors and attitudes among younger students and older students; and research to clarify the relationship between cheating and religiosity.
So give them a chance to appeal.
1) The rain is not really random, since only when droplets get large enough do they drop to the earth. To get large they will accumulate whatever is closest around them, meaning a sheet of evenly-spaced vapor (due to the diffusive properties of gas) quickly becomes a sheet of larger droplets evenly spaced. And this even spacing falls to the ground - granted with some intervention by the wind etc but the point is the rain is not all that random.

2) The same thing happens on the surface of the table, right? Smaller droplets converge into larger ones as more rain falls and pushes them together. And there is a maximum size of dot before it turns into a lake and runs off the table. So eventually you get what tends to be a fairly even distribution of dots of a certain size.

Anyway I could be totally off-base with all of this, but let me just say this is a fascinating problem and what a curious mind to have come up with it!
How has Docusign not been mentioned? Speaking from a developer perspective, their API is far and away the most flexible and easiest to get started with. Integrating with Adobe will definitely give EchoSign a bit more visibility (they really focused on consumers vs. enterprise before anyways) but I think consumers will want a separate solution anyways and enterprise will continue to choose the market leader (something like 95+ of the fortune 100 use Docusign already).
Actually, in my area, they have. The job postings lately are as much as 50% higher than a few years ago, for basically the same job.

In fact, I left my last job because they weren't paying me what I felt I was worth. I signed on with a new company for a huge raise, among other things. The old company is now trying to hire 6 people at what I now make. And as far as I know, they're failing to get them. I know my current company has failed to find anyone at a slightly lower salary than mine.

Companies are extremely resistant to changes in salaries. It takes a pressing need to get them to bump the salary up for a position. That's partly because it throws their budget off, but also because that means their existing employees are being underpaid, and they risk losing them as well, should they find out... Unless they also bump their pay up, destroying the aforementioned budget again.
I used to work next door to these guys. Excellent product and sharp team. Congratulations!
I think you are reading, look at what they made me do into a situation better described by look at the impact of my emotional reaction to this course of action.

The first paints you as a helpless victim of circumstances. The second one takes responsibility for ones poor actions, and charts a course to do better in the future.

There is a world of difference between the two.
In a previous life I was a sound engineer. Under controlled conditions, my own listening equipment and lossless source files, with which I am familiar, I can identify 64kbps vs 128kbps (p = .01), 128kbps vs 192kbps (p = .01), 192kbps vs 256kbps (p = .03), and probably 256kbps vs 320kbps (p = .07), n = 30, LAME=3.something for all tests. If you are in Austin, you can come over and watch me do this in person.

I have no doubt that the general population may be (statistically) unable to distinguish 128kbps vs 256kbps, but that says nothing about a minority of individuals, many of whom are large music purchasers.

The problem is that China is just now building those links. Brazil and Turkey have their links already in place (and fairly well cemented in history).

That said, I do see China (or some agglomeration of China + US) being a world power for the next generation – probably at least for the majority of Jim Rogers daughter's lifetime – but their trajectory doesn't look much better than the US's...it's just a bit more delayed. (Though, China's impending demographic crisis, depending on how bad it gets, could really bring all that down much sooner.)
This column-family/column/super-column lingo that Cassandra pulls out just makes it harder to understand its data model. In fact, it's quite simple:

Keyspace: a hash table that holds your application data. Okay, the table is distributed among nodes (i.e.,a DHT), but it's still a hash table;

Row: an entry in the above hash table where each value is composed by a collection of "column-families".

Column Family: a key-value table (I avoid to call it a hash table because I don't remember if it's implemented as such). A better name for this thing would be 'Attribute Set'.

Column: it's a key-value pair (with timestamp). Thinking about it as a column just blurs the concept. Better name: 'Attribute'.

Note: it's possible to have a different set of attributes on a per-row basis (for the same Column Family), so this concept of 'column' breaks quite easily.

Super-column: key-value pair where the value is yet another key-value table! Better(?) name: 'Super-Attribute'.

Then Cassandra data model is in fact a nested set of key-value tables while dynamo's model is flat (just one level hash table). Oh! Last but not least, it's not a column-store. It's on-disk storage is row-oriented.
Obama and Boehner had the outlines of a 10 year, 4 trillion deal that had some pain for everyone. For about 24 hours.

Unfortunately, that would have been a victory for Obama (and the country, incidentally). So it's a no-go as far as the Tea Party is concerned, which meant Boehner had to back out. Nevermind that these are people who've been shrieking about the deficit since January 2009.
I really wish he would not throw away Windows as a platform, considering Apache.org win32 builds make up more than 50% of their downloads. Even MySQL downloads in 2009 where something like 60% win32 and that was 2 years ago.

There is so much potential here that not having good Windows builds basically means you're missing out an extra 30% of production systems and 70% of development system. As in: you could double your numbers easily.

It's extra adaptation and growth.

It's an engineered distraction. We (led by the media) far for it every time.

Just like the nonsense about the "mosque at ground zero" - remember that? Notice how all the nonsense vanished?

Remember the debt is stuff we've already "bought" it's not the future budget and has been raised dozens and dozens of times, under every kind of leadership or lack thereof. This is just a puppet show - one side makes the show and the other side sits memorized and doesn't look at what else is going on.

Just imagine if we actually had this much effort by news outlets into health care reform (not the health insurance fiasco we got instead). We might have gotten an actual progressive solution.
Most modern browsers display Unicode domains only for TLDs that have a character set policy that prevents homograph attacks. Newer IDN TLDs (like .рф) also have restrictions -- .рф only accepts Cyrillic domains, for example.
Yes, I wrote my comment in a bit of a hurry (as evidenced by the ridiculous typo I made). I could be trite and say that "Singapore is where a capitalist moves when that capitalist really wants to move to China." But off-handed insults aside, he is still definitely betting on a period of Chinese ascendency.
one of the real problems in current testing is that it requires very little of the students creativity or originality. right from school you are told there is one answer to a question and one explanation that is better than others. your job as a student ( you are told) is to know that answer or to remember/understand that explanation. how different do you think students answers will be from each other?

Asking students not to open a browser to hunt for information is akin to not opening text books. not going to happen. when you are asking for an proven explanation the best you can expect is modified regurgitation of a know existing explanation. there are times when this is not as straightforward as it seems and there is effort required to do so.

the person really getting the short straw is the student. after paying a hundred grand, to sit in a class, they spend time understanding others opinions, instead of coming up with an original/fresh understanding of the problem.

'studying' or working on problems as a group is not going to go away. working as a group is the best way to stay motivated and focused when you are have 20 + course credits a semester. the best classes i have been in are those where the instructor divides the class into work groups and them adjusts the score by the individual members scores based on their contribution to a group ( much more real word scenario)

the authors efforts to creatively test the students and his success in dong so underscores my point. the system has the wrong incentives. more so for the students by not testing for their ability ,creativity, skills and understanding.

i really do feel for the author. i feel his pain and dissapointment and i hope things get better for him and his class. there are more uncaring/misguided teachers than bad/hopeless students.and i hope this teacher does not turn that dark corner. and we all know , there needs to be just one great teacher to set a student in the right path.
good luck .

As someone who has recently learned C# and known Scala for a while, I am very impressed with what C# has to offer as a language. However, it is not nearly as well-designed as Scala. Microsoft has piled on feature after feature to the point where many C# are features either mostly deprecated and replaced by newer features or else do not mix well with new language features. Some examples include:

-generic vs non-generic types. For instance, when using the Process class, you have to use StringDictionary.

- Actions and delegates vs lambdas. This is made more painful by the fact that C# handles the void return type specially, so that there is no way to create a Func<void>. Also, it means that if you want to support higher order functions that support both a void and a generic return type you have to write two different functions.

- ref and out parameters with lambdas. They just... don't mix!

- out parameters vs 4.0 tuples. Really C# needed syntactic sugar for multiple return types long ago, but the idiomatic way to do this in C# is with a feature that simply does not play well with functional programming.

There are other things that make Scala nicer as well.

-In Scala every statement is also an expression and Scala has the bottom type, which again makes writing functional code much simpler.

-Scala's collection's library is superior. It has functional collections and it's design enables overriding methods to have much more sensible static return types.

-Scala's way of extending class functionality with implicits is more powerful and object-oriented than C#'s extension methods. In fact, Scala in general feels much more OO than C#.

-Scala has a form of controlled multiple implementation inheritance (traits) that I really miss in C#.

These are just the practical things I can think of on top of my head that I miss in C# versus Scala. On the other hand, I get the impression that C# was originally designed to be a more performant Java by hybridizing it with C++. It's richer value type system, the fact that class methods are non-virtual by deafult, and the ease by which one can drop into unsafe code mean that one can port a lot more performant C-style code to C# than on any JVM-originating language, which I think is C#'s greatest strength compared to Scala.

Still, I think if people gave Scala a chance they would find it to be a very clean, productive, and well-designed language compared to C#. That alone may not be enough to convince people to switch to Scala in droves, but enough so that people who want to target both platforms will be willing to consider Scala as a solution rather than to use something like Mono.

Both this and the write-up are curiously short on roadmaps or predictions though, and the Electrolysis page on the Mozilla wiki only talks about work already done (content processes in Fennec, the mobile version of Firefox, and out-of-process plugins). Given the benefits this will bring, I'd love to know when it's likely to arrive!

I know some Mozillans (?) sometimes post here - anyone have any idea what stage Electrolysis for desktop Firefox has got to?
Yup, and if commit to it and suddenly realize you need a little more flexibility than the API provides, you're probably in a worse position than if you rolled it yourself.

So there I was, deadline from the client looming and my publishing piece still wasn't finished because using Scribus takes way longer than using InDesign since it lacks key features, UI polish, and usability. Rather than purchasing InDesign and get the job done so I could get paid, I decided to take several years off work, learn software development, and improve Scribus.

Wait... do people consider that a serious argument? Have they been drinking the open source kool-aid a little too much?
I gave up arguing with creationists long ago, but on the off chance you actually do want to improve your understanding: http://en.wikipedia.org/wiki/Macroevolution#Misuse

Who sets these principles? I ask because FSF has bashed Apple and MS at various points in time. If the FSF is writing the religious-book here, then you're not supposed to work with the cloud, you're not supposed to use to chromeOS notebooks and boy you should really go dump those smartphones since they're either proprietary or open-but-not-quite.

In that same vein, code inside a car's sensors isn't open sourced and Toyota had a rather messy couple of months because of it. So boycott cars too ? Build your own car ?

I really don't get the excuses people come up with to complain about people getting shit done. A "principles based" fight is being fought in politics all the time; fat load of good that's doing.

For comparison's sake, if the Sun were 600au away, it would be as bright as the full moon. This red dwarf is much less luminous as it is, being at 1000au would make it bright, but unremarkable.

To put things more into prespective, this red dwarf at 1000au distance would be as bright as our Sun 50K au away (or 0.8 ly away).

No, no, no! Please don't let GMail and G+'s new look become a new fad. The white space around every element is very wasteful and obnoxious. Not everyone has huge resolutions and those that do don't appreciate having to scroll several times just to see past the first 4 or 5 entries in a list view.
On the other hand, it's not worth it if it takes more than double the effort to maintain Windows support. You can increase your market by 2x and still lose if it requires 3x the effort.
I see new gTLDs as a good thing.

Obviously the registrars are in it for the money but this will be like the new .com domain but with several advantages:

1. The high price will eliminate squatting;

2. The lack of squatting will greatly reduce phishing through real-looking domains;

3. The price is low enough that startups with serious series A/B funding will probably buy their gTLD; and

4. gTLDs may well be out of the jurisdiction of ICE and the US government (unlike .com and .net domains as witnessed by recent seizures).

Bring it on, I say.
but the future career risk is nil

I think that is the biggest part. In SV and other good startup scenes its very well known and understood that startup experience is looked upon positively.

So even if your startup blows up you can always get a great job at Xcorp afterwards

They why did you say:

"Not only is Cassandra’s terminology confusing it’s downright misleading. Row, Column & Key all have existing semantics in the land of databases. To make matters worse, Cassandra’s definitions are not even orthogonal to the existing ones — they exist in a difficult state of quasi-synonymity."

You assumed that the RDB definition of those words was absolute, and didn't bother to question if a different kind of database would use them somewhat differently.
