Hey Mom, I know you’re dying to know how my semester is going so I thought I’d share with you some of the assignments I’ve been working on. I just finished my first chemistry lab project involving drugs! Yes, drugs, but not the ones you’re thinking about. We worked with Sulfanilamide, Phenacetin, Acetaminophen, and your favorite, Caffeine. The goal for the experiment was to determine where the drugs may reside according to their properties. We learned that there are parts in the cell that are…

5.What is the purpose and recommended use of the measure? The BDI-II is a self-report questionnaire that measures the severity of depression with 21 items (Bringmann, Lemmens, Huibers, Borsboom & Tuerlinckx, 2015). The highest score that can occur on this measure is 63 (highest severity of depressive symptoms), and the lowest score that can be achieved is 0. The items were designed to identify symptoms of depression as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth…

The Real Results of the Van Boven/Gilovich Study Does experience provide more happiness than material goods? A research study done by Van Boven and Gilovich (2003) explores this question by surveying and performing experiments on different populations. A press article, written by Dr. Dean (2008), presents an argument on this topic using the study as reference. While the press article conveys a message similar to that of the study, its technical inaccuracies, overgeneralizations, and its claim…

The South vs. The South William Freehling, The South vs. The South. (New York, NY: Oxford University, 2001) William W. Freehling is an American historian, and Professor of History and Otis A. Singletary Chair in Humanities at the University of Kentucky, and is the author of The Road to Disunion, Volume I: Disunionists at Bay, 1776 – 1854, which won the Owsley Prize. William Freehling's The South vs. The South book is two hundred and thirty-eight pages and divided into ten chapters. The…

Mind Body Identity The identity theory of mind holds that states and processes of the mind are indistinguishable to states and processes of the brain. it need not hold that the mind is identical to the brain. Idiomatically on a general basis we often say ‘She has a good mind’ and ‘She has a good brain’ interchangeably but we barely say ‘Her mind weighs fifty ounces’. Thus it is about identifying mind and brain as being a matter of identifying processes and maybe states of the mind and brain.…

In the article “The Happiness of Pursuit” by Jeffrey Kluger, multiple tables are provided showing different data and percentages on certain factors of happiness. Looking at the tables on the page title “Got Joy,” there was three in specific that caught my eye. The first being the one labeled “Then and Now” which shows the difference in percentages from 2004 to 2013 in whether people described themselves as optimists or pessimists. The percent of Optimist decreased from 70% to 50%, which can…

Herzberg’s Two-factor Theory The Two-factor Theory was developed by Herzberg, Mausner, and Snyderman (1959), following an investigation into the sources of job satisfaction and dissatisfaction, and included 200 accountants and engineers from Pittsburgh, America. Applying the critical incident technique, the study’s subjects were asked to tell their interviewers about the times that they felt exceptionally good or bad about their present jobs or any previous jobs. They were also requested to…

So, t will be our test statistic. In our case, the computed value of t is .341, which is well within the zone of acceptance. So we can accept the hypothesis that μ = 7. The Independent Samples t-Test can only associate the means for two (and only two) groups. It cannot make comparisons…

RAID level 5 works with any number of disk equal or greater than 3 and places a parity sum on one disks in the set to be able to recover from a disk failure. (Striped blocks with distributed parity.) The parity calculations are done in a RAID 5 set using XOR. We assume a small RAID 5 set of four disks and some data is written to it. On the first three disks we have the binary information 1010, 1100 and 0011, here representing some data, and now calculate the parity information for the…

Dangers of cell-phone use while driving are exhibited in this article. Furthermore, participants completed three driving conditions; driving while conversing, driving while talking on a hands-free device, and driving while the other partner could see a video of both the road and the drivers face. Testing was also done to see if visual information increased awareness and reduced the negative effects accompanied by cell-phone distraction. The authors sufficiently review other research based on…
