Abstract
This paper reports that the results of the experiment were consistent with the hypothesis that people who play video games at least 10 hours a week will have improved reaction times over people who do not play video games. The author points out that, for the purposes of this study, gamers were defined as participants who played video games ten hours a week or more, while non-gamers were defined as those who played video games less than ten hours a week. The paper relates that an online survey was created through www.surveymonkey.com and administered to obtain demographics, information about the gaming habits of participants and whether or not they participated in any other activity that could increase their reaction times.

From the Paper
"Laming (1968) found that reaction times for recognition reaction time tests averaged 0.384 seconds. The means obtained from the current experiment are lower than the expected means for a reaction time test. The mean reaction time for gamers was 0.248 seconds, while that of non-gamers was 0.305 seconds. This may be due to the fact that the measures used in the current experiment were more accurate than those used by Laming or because the stimuli presented were simpler."

Abstract
The mitsunobu reaction, discovered in 1967, involves the stereospecific reaction of an alcohol and a carboxylic acid in the presence of triphenylphosphine and diethyl azodicarboxylate (DEAD) to give an ester. This paper provides an overview of this chemical reaction and presents explanations via numerous diagrams and figures.
From the Paper
"In 1976, it was found that the formation of nitriles is also easily reached when cyanide is used as a nucleophile under Mitsunobu conditions.10 Recently, however, acetone cyanohydrin has been used as a source of hydrogen cyanide for this reaction (see figure 7). With a comparable yield and a less toxic reagent, acetone cyanohydrin is a suitable replacement for HCN.11 In this system, similar to other Mitsunobu systems, sterically hindered secondary alcohols tend to give poor yields."

Abstract
Studies of reaction times have been of interest to a wide variety of people for several centuries. Among one of the industries that stands to benefit the most from a more comprehensive understanding of reaction times is the automobile insurance industry, which charges customers premiums based on the risk that they might get into an accident. There is reason to believe that this propensity is directly correlated to reaction time. This paper shows that, whereas, in simple reaction time experiments, there is only one stimulus and one response, in choice reaction time experiments, the user must give a response that corresponds to the stimulus. This system most closely resembles that of driving. The paper shows that insurers have found that reaction time is determined as the time required for a driver to perceive a hazard and apply the brakes or turn the steering wheel. As a result, reaction time tests used to measure driving competency would have to focus on this particular metric.
From the Paper
"Other studies have shown that reaction times improve when there is a sense of anticipation in the subject, which bodes poorly for the method?s use to the automobile insurance industry. Sanders (1998, p. 21) This has two implications to the industry: first, people with higher reaction times will tend to be better drivers and people who engage in reaction-time intensive activities such as video games will have higher reaction times. Secondly, testing will not reveal skills as well as might have been thought. Brebner and Welford (1980) report that reaction times are faster when the subject has been warned that a stimulus will arrive soon."

Abstract
The writer defines the test, discusses the results and analyzes the implications. The dependent variable in the study is behavior, specifically the reaction time (RT) of student?s responses. Two types of reaction times are included in the test: simple and discriminative. The simple reaction time involves a purely physical stimulus while the discriminative reaction time was measured in the same way, but with the addition of an auditory stimulus.
From the Paper
"Within this study, there were several instances of measurement error. One example is that the weight of the rulers between the different reaction time group participants was not standardized. Another example is that in the study of discrimination reaction time, the use of ?beep? and ?boop? was not reversed to determine if both words were equal in regards to the reaction time. A final example is that all groups did the simple reaction time first. This is a possible error in the study because all the figures for the discrimination reaction time study could have been confounded by the fact that the participants were used to the experiment or that it was later in the day."

Abstract
The paper deals with a very detailed investigation into how the kinetics of a reaction changes from alterationss in pH, the concerntration of reactants and the addition of a catlyst in a homogenous solution. Also included is the most effective, yet efficient manner, of determining the rate of the reaction including detailed mathematical calculations. There is a lot of experimental data as evidence included and a detailed practical guide of how the investigation was undertaken and numerous discussions.This paper is essential as a reference for those studying reaction kinetics.
From the Paper
"Investigate the kinetics of the above reaction and thus attempt to find a rate equation for the reaction and also establishing the best method to determine the rate of the reaction. I will do this by varying the concentrations of Iodide ions, H+ ions and Hydrogen Peroxide to generate the rate equation, I will also try to find the effect of a catalyst: Molybdate ion on the rate of reaction and also if the amount of catalyst is relevant in a homogenous reaction. The rate will be found using the iodine clock reaction and also by the use of a pH meter and a colorimeter, and these methods will be assessed to help determine the best method of analysis."

Abstract
In the medical field, a medical professional's first duty is to do no harm to their patients. However, studies have shown that often times the care that injured or ill people received not only occasionally worsened their condition, but also in some instances were proven fatal. In particular adverse drug reactions are one of the most common examples of this tragic scenario. This paper discusses the increased direct-to-consumer marketing efforts of pharmaceutical companies, the types of adverse drug reactions and finally the incidence of drug reactions.
From the Paper
"A major cause of morbidity and mortality, worldwide, is adverse drug reactions, as caused by either immune or non-immune mechanisms. These reactions are the most common iatrogenic illnesses, which complicate between five and fifteen percent of therapeutic drug courses. More than 100,000 deaths, in the United States, are characterized by serious, adverse drug reactions, each year (Riedl & Casillas, 2003, p. 1781)."

Abstract
This paper discusses the concept of postmodernism of resistance and postmodernism of reaction. It explores this concept and use examples of art to illustrate what is meant by this contrast. The paper describes and discusses art works by Hans Hofmann, Damien Hirst and Sherrie Levine and shows how these artists portrayed postmodernism of resistance or postmodernism of reaction.
From the Paper
"Instead, I would argue that the art world needed to wait another ten years to see true examples of "postmodernism of resistance" - in the form of artwork such as Damien Hirst's, which embodied what has been termed a "striking analogue for the relationship between aesthetic and lived experience" (Hopkins 228). Here was something that was utterly different, in that it was not merely a reaction against the formalism of Modernism. Instead, it embodied a sweeping paradigm shift, relocating art within the paradigm of installation. In so doing, it resists Modernism to the extent that it even places new demands upon the viewer of art - for example, often she must move. Indeed, her movement may inform the meaning of the artwork - something scarcely contemplated in the formalism of Modernism. Moreover, rather than form following function, function becomes irrelevant."

From the Paper
"Alternatively, the many friends I had that attended private school had an overwhelmingly more positive experience than I encountered in public school. If a student became depressed or violent in their private school, the issue was noticed immediately due to the small setting and was taken care of swiftly. Of course, cliques, being a product of human nature, existed on a smaller scale in my friends' schools, however, these cliques were less cohesive. This appears to be because the small setting gave everyone the feeling of belonging to the same big group, which allowed them to avoid splintering into smaller ones as is common in the larger public school environment."

Abstract
This paper presents an assessment of the economics of health care costs. The paper argues that the problem is a complex maze of related issues such as funding mechanisms, delivery structures and individual responsibility. Additionally, the paper recommends a national health care system for managing family health care costs that is based on universal access to health care.
From the Paper
"Health care economics is entering another state of turmoil in the United States as the moderating effects of the managed care concept on increasing health care costs appears to have run its course. The Congress and state governments believed the promises of managed care proponents that managed care would lower health care costs dramatically and are resisting rapid increases in health care costs. Managed care companies are responding by dropping governmentally-funded patient groups including Medicare and Medicaid raising charges to..."

Abstract
This paper describes an experiment in which DNA was extracted from the organism Caenorhabditis elegans to be amplified and electrophoresed. The author reports that polymerase chain reaction (PCR) was used in the experiment to amplify the DNA and after electrophoresis was finished, a photograph of the gel was obtained. The author also explains that the migration distance of the bands was measured and a graph of the molecular weight of the bands was created. The paper states that this process allowed the isolation of homeobox genes, which are of great importance in many different organisms for patterning and segmentation.

From the Paper
"When it comes to unlocking the mysteries of organismal development, it all comes down to genes. However when genes are to be analyzed, a little is often not enough. This is where polymerase chain reaction (PCR) comes into play. PCR is a powerful and fast method, for which the ultimate desired outcome is the amplification and quantification of DNA "from a minimal initiating amount in vitro.
In order for PCR to occur, template DNA is first denatured. Annealing primers, or often degenerative primers which use every possible codons for unknown DNA sequences."
