Youth who participate in service activities differ from those who do not on a number of key demographic characteristics like socio-economic status and other indicators of risk; and most studies demonstrating positive outcomes among service participants employ small non-representative samples. Thus, there is little evidence as to whether the outcomes associated with service participation are similar among students with varying levels of risk. The National Household Education Survey of 1999, a large nationally representative cross-sectional data set that focused on community service, was analyzed to investigate associations between the risk status of 4,306 adolescent students (50.2% female; 63.3% European American, M age?=?15.9), their participation in community service, and their academic adjustment, behavioral problems, and civic knowledge. Because adolescents who participate in service differ from those who do not with respect to demographic characteristics, propensity score analyses were used to correct for potential selection bias in the examination of these relationships. Analyses tested competing theoretical models of service??protective versus compensatory??among students at varying levels of risk, and suggested that service acts as a compensatory factor with respect to academic, behavioral, and civic outcomes. Propensity score analyses revealed patterns suggesting that, in some cases, students with certain demographic profiles that are themselves related to the likelihood of service participation may benefit from service participation more than others. Findings are discussed in terms of their significance for adolescent development, for planning service programs, and for educational policy.  相似文献

Recent media attention has increased interest in behavioral, mental health, and academic correlates of involvement in bullying. Yet, there has not been much interest in investigating the co-occurrence of other health-risk behaviors, such as gang membership, weapon carrying, and substance use. The potential influence of contextual factors, such as youth ethnicity, urbanicity, and school characteristics, also has been overlooked in previous research. The current study examined different subtypes of involvement in bullying—as primarily a victim, as primarily a bully, as both a victim and bully, and no involvement—and the association with significant health-risk behaviors, including engaging in violence and substance use, as well as academic problems. The analyses use self-report data from 16,302 adolescents (50.3 % female, 62.2 % Caucasian, 37.8 % African American) enrolled in 52 high schools. A series of three-level HLM analyses revealed that bullies and bully/victims were generally at greatest of risk of being involved in violence, engaging in multiple types of substance use, and having academic problems. These findings extend prior research by emphasizing a potential link between involvement in bullying and multiple health-risk behaviors, particularly among urban and African American high school youth.  相似文献

Existing research suggests that sexual minority youth experience lower levels of well-being, in part because they perceive less social support than heterosexual youth. Sexual minority youth with strong family relationships may demonstrate resilience and increased well-being; however, it is also possible that the experience of sexual stigma may make these relationships less protective for sexual minority youth. Using two waves of data from the National Longitudinal Study of Adolescent Health, we explore the links between same-sex attraction, family relationships, and adolescent well-being in a sample of over 13,000 7th–12th grade adolescents (51 % female, 52 % non-Latino/a white, 17 % Latino, 21 % African American, and 7 % Asian). Specifically, we examine whether lower levels of parental closeness, parental involvement, and family support among same-sex attracted youth explain in part why these youth experience increased depressive symptoms and risk behaviors, including binge drinking, illegal drug use, and running away from home, relative to other-sex attracted youth. Second, we ask whether family relationships are equally protective against depressive symptoms and risk behaviors for same-sex attracted and other-sex attracted youth. We find that same-sex attracted youth, particularly girls, report higher levels of depressive symptoms, binge drinking, and drug use in part because they perceive less closeness with parents and less support from their families. Results also suggest that parental closeness and parental involvement may be less protective against risk behaviors for same-sex attracted boys than for their other-sex attracted peers. Findings thus suggest that interventions targeting the families of sexual minority youth should educate parents about the potentially negative effects of heteronormative assumptions and attitudes on positive adolescent development.  相似文献

This article argues that if the introduction of genetically modified crops (GM crops) in developing countries is to be successful, we can and should not evade questions of access and control of technology. It implies probing into the experiences, perceptions and understanding of GM crops by the prime user: the farmer. Exactly in these respects the scholarly literature is remarkably silent. We know little about farmers' experiences and perceptions of GM crops' potential risks and benefits. This is evident when concentrating on a major GM crop – Bt cotton – and studying this in the context of China, its second largest producer in the world. Based on the results of a large survey, we demonstrate that Chinese farmers' awareness (‘having heard of’) and their understanding (‘being able to explain’) of Bt cotton is low. This may lead to ill-informed, distorted risk perceptions and a general inability to relate agricultural production problems to the specific nature of transgenic cotton cultivation. A great majority of the farmers find that the Chinese seed market was liberalised too early, in turn leading to a high incidence of ‘stealth transgenics’ or illegal seeds, the undermining of farmers' trust in private institutions, and a weakened biosafety regime. This finding points to the need for continued state intervention in the seed market, particularly in a developing context. Finally, we have discovered that farmers report a significantly lower reduction in pesticide use by Bt cotton than found in other studies. As suggested by recent research, we suspect that the higher pesticide use is necessary to control secondary pests – i.e. pests other than the cotton bollworm. We present empirical evidence that Chinese farmers perceive a substantive increase in secondary pests after Bt cotton was introduced.  相似文献

Drawing on comparisons with cooperative and competitive non-state health care provision around the world, this article analyses non-state provision of health services in post-Soviet Uzbekistan and Kazakhstan. It explores the conditions in which non-state provisions remain cooperative or become politicised and contrasts the relations between NGOs and the state in Uzbekistan and Kazakhstan and the way they became politicised in the Middle East. In contrast to Western conceptions of NGOs, Central Asia's health NGOs cooperate with state agencies to serve their constituencies. In contrast to the perceptions of Central Asian governments, health-oriented NGOs do not aim to politicise health care. Donor support to Central Asia's health NGOs has created civically oriented actors that fill gaps in the state's capacity and enable governments to better serve their populations.  相似文献
