This study aimed to explore the role of depression as a moderator of sociocultural influences on eating disorder symptoms.
A sample of 509 adolescents (56% female) completed self-report questionnaires assessing depression, body dissatisfaction,
drive for thinness, bulimic symptoms and sociocultural influences on appearance from family, peers and the media. Both girls
and boys displaying high levels of depressive symptoms perceived stronger media and peer influences on appearance. Among girls,
eating disorder symptoms were directly affected by sociocultural influences, in particular media influences, as well as by
depression. However, depression played only a limited role as a moderator of these relationships. Among boys, sociocultural
influences and depression revealed fewer direct effects on eating disorder symptoms. However, depression had a greater moderating
effect on these relationships. Future research into the role of depression may increase the understanding of gender differences
in body dissatisfaction, drive for thinness and bulimic symptoms. 相似文献

Previous work on peer victimization has focused primarily on academic outcomes and negative indicators of youth involved in bullying. Few studies have taken a strength-based approach to examine attributes associated with bullies and victims of bullying. As such, we examined developmental trajectories of moral, performance, and civic character components, and their links to bully status using data from 713 youth (63 % female) who participated in Wave 3 (approximately Grade 7) through Wave 6 (approximately Grade 10) of the 4-H Study of Positive Youth Development. Latent growth curve analyses indicated that moral character was stable across waves, whereas civic character increased slightly by Wave 6. Trajectories for performance character varied; some youth alternatively displayed positive versus negative growth. Youth who reported bullying behavior reported lower initial levels of moral, performance, and civic character as compared to youth not involved in bullying. Bully–victims reported lower initial levels of moral and civic character as compared to youth not involved in bullying. Implications for future work examining character-related components in the context of peer victimization are discussed. 相似文献

Charles Bram Cadsby Rachel Croson Melanie Marks Elizabeth Maynes 《Public Choice》2008,135(3-4):277-289
This research concerns how costs and benefits affect the voluntary provision of threshold public goods. Cadsby and Maynes (J. Public Econ. 71:53–73, 1999) hypothesized that the difference between the value and cost of such a good, its net reward, influences the likelihood of provision. Croson and Marks (Exp. Econ. 2:239–259, 2000) focused on the ratio of group payoff to total cost, the step return. We find that step return is the best predictor overall, although net reward has some impact, negatively affecting the probability of provision with inexperienced participants and positively affecting it with experienced participants. 相似文献

This article examines German national parties' use of the Internet in the 2002 federal election. Its main goals are to determine what the parties were doing in their online campaigns and how far their use of the Internet can be understood in terms of two party-specific variables – organisational size and primary goal. These questions are of significance given the relatively limited study of parties' use of the net in Germany in the comparative literature on this topic. Also, research on parties' use of the Web across countries has suggested that while context does produce differences in approach, partyspecific factors also play a major role in determining online strategy. The article attempts to investigate these questions systematically by examining nine German parties' use of the Internet (specifically websites, e-mail, and intra-nets) using questionnaire data from national party personnel and content analysis of web pages. Our findings show that while the divide between major and minor parties can be seen quite clearly in the German context in terms of website quality and visibility, evidence to support the impact of party outlook in shaping parties' online strategy can also be found. In addition, the study reveals that major parties are now beginning to take the Internet very seriously as a communication tool, particularly in terms of election campaigning. 相似文献
