"The red zone": temporal risk for unwanted sex among college students

The "red zone" usually refers to the first few weeks of the first semester at college, when female students are believed to be at greatest risk for experiencing unwanted sex. We tested this notion using data from a survey study of 207 first-and second-year students (121 women, 84 men) at a small, liberal arts university. Results demonstrated only one significant elevation in incidence rates of first- and second-year women's unwanted sexual experiences (sexual touching, attempted and completed anal, oral, and vaginal sex), between the end of the first month and fall break (mid-October) during the second year at school. Previous research and local information about the relevant behaviors of sorority and fraternity members is discussed in light of these findings to provide heuristic material for further empirical testing. Because risk may involve both temporal and situational factors, systematic collection and dissemination of local data are recommended.     

Experimental evaluation of rigor mortis IX. The influence of the breaking (mechanical solution) on the development of rigor mortis

In criminal proceedings involving illegally manufactured substances, evidence demonstrating the manufacture is required for successful prosecution. In many circumstances the presence of manufacturing equipment and 'recipes' are clear indicators. However establishing chemical links between starting materials and products would be beneficial additional evidence in such circumstances. Isotope analysis is becoming more commonly employed in disputes over authenticity and provenance of materials such as food stuffs or pharmaceuticals [S. Benson, C. Lennard, P. Maynard, C. Roux, Forensic applications of isotope ratio mass spectrometry--a review, Forensic Sci. Int., 157 (2006) 1-22]. We report here the results of an isotope study investigating a link between hexamine used as a starting material and the product explosive RDX, manufactured using the Woolwich process. Isotopic composition of hexamine and RDX was analysed by stable isotope ratio mass spectrometry. Five different hexamine samples were selected from a group of eleven for use in this study. One of the five hexamine samples was used twice, providing data on the reproducibility of the synthesis. Carbon and nitrogen isotope analysis of the hexamine starting material and RDX products reveals a reproducible relationship between reactant and product.     

A three-year follow-up of the performance of a class of state police academy graduates using the MMPI-2

Research has demonstrated the utility of the MMPI-2 in identifying good and poor performance, dissatisfaction, termination, low performance ratings, unsatisfactory and satisfactory criterion groups, problematic behavior, corruption, and aggression. There is much research to suggest that certain patterns of responding to this measure by officer applicants predict job performance behaviors that supervisors and police executives view unfavorably. This study illustrates the fact that variables which are likely to predict police performance are less obvious and more subtle. Discussion centers on repression and underlying hostility.

New markets,old struggles: Large and small farmers in the export agriculture of coastal Peru

Although the output of high-value crops in Peru has increased during the era of ‘globalization’, producers still tend to contextualize this development in relation to the 1969 agrarian reform. Considered here is how large and small farmers in the Cañete region perceive the changes that have occurred in agriculture since a generation ago, with particular reference to market competition and the implications of the new economic conditions for environmental sustainability. Despite the fact that farmers located at each end of the rural hierarchy experience the economic impact of globalization differently, small cultivators exporting their produce to the international market being particularly vulnerable to its laissez faire regime, they nevertheless share a common belief in the importance of agriculture for the well-being of the nation. The latter, it is suggested, is a discourse that reproduces much of the ideology associated historically with the agrarian and foundation myths.
