Despite recent declines in overall sexual activity, sexual risk-taking remains a substantial danger to US youth. Existing research points to athletic participation as a promising venue for reducing these risks. Linear regressions and multiple analyses of covariance were performed on a longitudinal sample of nearly 600 Western New York adolescents in order to examine gender- and race-specific relationships between jock identity and adolescent sexual risk-taking, including age of sexual onset, past-year and lifetime frequency of sexual intercourse, and number of sexual partners. After controlling for age, race, socioeconomic status, and family cohesion, male jocks reported more frequent dating than nonjocks but female jocks did not. For both genders, athletic activity was associated with lower levels of sexual risk-taking; however, jock identity was associated with higher levels of sexual risk-taking, particularly among African American adolescents. Future research should distinguish between subjective and objective dimensions of athletic involvement as factors in adolescent sexual risk.Research Scientist at the Research Institute on Addictions of the University at Buffalo.

The absorption of the cultural sphere into the commercial sphere signals a fundamental change in human relationships with troubling consequences for the future of society. From the beginning of civilization to now, culture has always preceded markets. People create communities, construct elaborate codes of social conduct, reproduce shared meanings and values, and build social trust in the form of social capital Only when social trust and social exchange are well developed do communities engage in commerce and trade…. When the commercial sphere begins to devour the cultural sphere … it threatens to destroy the very social foundations that give rise to commercial relations. 1 相似文献

Four presumptive blood tests, Hexagon OBTI, Hemastix(R), Leucomalachite green (LMG), and Kastle-Meyer (KM) were compared for their sensitivity in the identification of dried bloodstains. Stains of varying blood dilutions were subjected to each presumptive test and the results compared. The Hexagon OBTI buffer volume was also reduced to ascertain whether this increased the sensitivity of the kit. The study found that Hemastix(R) was the most sensitive test for trace blood detection. Only with the reduced buffer volume was the Hexagon OBTI kit as sensitive as the LMG and KM tests. However, the Hexagon OBTI kit has the advantage of being a primate specific blood detection kit. This study also investigated whether the OBTI buffer within the kit could be utilized for DNA profiling after presumptive testing. The results show that DNA profiles can be obtained from the Hexagon OBTI kit buffer directly. 相似文献

This paper examines the valuation tools available to measure the financial contribution that public affairs activities add to the corporate bottom line. The paper begins with a consideration of the state of quantification in public affairs. Next, theoretical frameworks for broad classes of valuation methodologies are presented. Specific models applied by companies are also examined, outlining their advantages and limitations. The paper concludes with recommendations for implementing quantitative financial measures and opportunities for future research. Copyright © 2003 Henry Stewart Publications 相似文献
