Social, academic, emotional functioning and social support of 99 ninth-grade Asian American students were investigated using standardized measures. When compared to 404 ninth-grade Caucasian adolescents who had attended the same school, Asian American students exhibited less delinquent behavior and performed better academically. However, they were significantly more isolated, more depressed and anxious, less apt to be involved in after school activities or seek help for their problems, and internalized their social problems. Also, they had fewer role models and less social support, underscoring the psychosocial and emotional plight of Asian American adolescents and the dire need to establish proactive outreach programs.This work was supported by NIMH grant #MH41569-07. 相似文献

This paper describes the evaluation of a three year Initiative run by the YMCA. The aim of the Initiative was to set up 30 different projects in YMCA centres in England, to provide help and support to the parents of teenagers. The Initiative was evaluated by the Trust for the Study of Adolescence. Funding was agreed for 29 projects, which included group‐based courses, ‘Dads and Lads’ projects, mediation schemes, transition evenings, and families and computing courses. A variety of outcomes from these projects are identified, both for parents, young people, project workers, and the YMCA as an organisation. Key issues and learning points from the Initiative are also identified. Finally, some general comments are made about strategies to provide support to the parents of teenagers.

Abstract Pregnancy is potentially a stressful period for working women for ergonomic, psychological and organizational reasons, yet the well-being of women is seldom the focus of research on working during pregnancy. This paper reviews the literature on women's experience of being pregnant at work. It concludes that, while working conditions are usually not well suited to pregnant women, the majority of women encounter only minor difficulties and regard working in a positive way. However, for a minority of women working during pregnancy adversely affects their well-being. These are likely to be women working during pregnancy adversely affects their well-being. These are likely to be women who are most at risk from work-related stress at other times. The literature suggests that working during pregnancy has still to be accepted and accommodated by employers and colleagues. 相似文献

Ingestion of contaminated fish can be an important human exposure pathway for dioxins and furans emitted from waste incineration plants. A new method for calculating fish contamination resulting from dioxin and furan emissions has been developed to overcome some of the problems of those currently used. The method is based on evidence that the major determinant of fish dioxin and furan uptake is sediment concentrations. Only two steps are necessary to calculate fish tissue levels. Step 1: Calculation of the concentration of dioxins and furans in particulate matter entering the lake or pond, and hence, the resulting sediment concentration. Step 2: Calculation of fish concentrations utilizing fish-to-sediment ratios for the various dioxin and furan isomers. 相似文献
