Sleep habits around the world

The purpose of this study is to examine a relationship between sleep habits in college students at Clemson University and at The University of Vienna. Using the Pittsburgh Sleep Quality Index (PSQI), we define sleep habits as a) time they go to bed, b) time they wake up, and c) amount they slept at night. 324 Clemson participants and 292 Vienna participants from undergraduate psychology courses were asked to complete surveys regarding their sleep quality (PSQI). An independent sample t-test showed a significant difference in both the average times Clemson and Vienna students went to bed and woke up (p \u3c .001) as well as in the average total hours they slept at night (p \u3c .001). Our data findings suggest that Clemson students went to bed later, woke up earlier, and slept less on average than Vienna students

Effects on transgenic thuringiensis on European corn borer natural enemies and non-target Lepidopteran pests

Field corn, genetically engineered to produce a protein derived from Bacillus thuringiensis, was evaluated for its effects on larvae of black cutworm, stalk borer, armyworm, and corn earworm. No Btcorn effects were observed on larval survival, pupal weight, or days to adult emergence for black cutworm or stalk borer. Armyworms reared on Bt leaf extract were lighter-weight, delayed in development, and showed diminished survival rates. Corn earworm showed reduced survival and delays in development. In field tests of Bt and non-Bt corn, there were no differences between the two varieties in damage from black cutworm. Stalk borer caused less leaf damage to Bt corn. Armyworm and corn earworm did less harm to Bt corn leaves than to non-Bt corn leaves, but corn earworm survived to cause some damage to Bt corn ears

Auditory Attention and Comprehension During a Simulated Night Shift: Effects of Task Characteristics

OBJECTIVE: The current study investigated performance on a dual auditory task during a simulated night shift. BACKGROUND: Night shifts and sleep deprivation negatively affect performance on vigilance-based tasks, but less is known about the effects on complex tasks. Because language processing is necessary for successful work performance, it is important to understand how it is affected by night work and sleep deprivation. METHOD: Sixty-two participants completed a simulated night shift resulting in 28 hr of total sleep deprivation. Performance on a vigilance task and a dual auditory language task was examined across four testing sessions. RESULTS: The results indicate that working at night negatively impacts vigilance, auditory attention, and comprehension. The effects on the auditory task varied based on the content of the auditory material. When the material was interesting and easy, the participants performed better. Night work had a greater negative effect when the auditory material was less interesting and more difficult. CONCLUSION: These findings support research that vigilance decreases during the night. The results suggest that auditory comprehension suffers when individuals are required to work at night. Maintaining attention and controlling effort especially on passages that are less interesting or more difficult could improve performance during night shifts. APPLICATION: The results from the current study apply to many work environments where decision making is necessary in response to complex auditory information. Better predicting the effects of night work on language processing is important for developing improved means of coping with shiftwork

Isotopic Production Cross Sections in Proton-Nucleus Collisions at 200 MeV

Intermediate mass fragments (IMF) from the interaction of $^{27}$Al, $^{59}$Co and $^{197}$Au with 200 MeV protons were measured in an angular range from 20 degree to 120 degree in the laboratory system. The fragments, ranging from isotopes of helium up to isotopes of carbon, were isotopically resolved. Double differential cross sections, energy differential cross sections and total cross sections were extracted.Comment: accepted by Phys. Rev.

Smart & Savvy Students: Year 2

Smart & Savvy Students\u27 (SSS) main goal is to convert scientific psychological articles to understandable pieces of information for general audiences. We have a Twitter feed, Facebook page, and Instagram to spread the information to Clemson\u27s student body and other audiences that we post to 3 to 5 times a week. Each tweet contains a 140-character tip written in a dialogue format. The tweets include links to the Facebook page, which has more information. The Facebook page provides links to scientific sources that support our claims. These links provide students with the opportunity to learn more about the topics. In addition, we post to an Instagram account that links back to Facebook and Twitter, which allows us to spread our information to the largest audience possible. Using popular social media, SSS targets students by including information on topics such as study skills, exercise and diet, and healthy habits, which can be applied in day-to-day life for more positive lifestyles
