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

Recent advancements in technology (e.g., social networking, texting) have created new ways for dating youth to relate to one another, including in abusive ways via “cyber dating abuse.” Cyber dating abuse is a form of teen dating violence that overlaps with other types of abuse (e.g., psychological) but also has several unique characteristics. Given the phenomenon’s limited presence in dating violence literature, we focus on identifying how experiencing cyber dating abuse relates to youths’ individual behaviors and experiences (e.g., substance use, sexual activity), psychosocial adjustment, school connection, family relationships, and partner relationships. A total of 3,745 youth (52 % female, 74 % White) in three northeastern states participated in the survey and reported currently being in a dating relationship or having been in one during the prior year. We found that experiences of cyber dating abuse were most significantly correlated with being female, committing a greater variety of delinquent behaviors, having had sexual activity in one’s lifetime, having higher levels of depressive symptoms, and having higher levels of anger/hostility. Further, cyber dating abuse appeared somewhat more strongly related to depressive symptoms and delinquency than did other forms of teen dating violence and abuse.  相似文献
