Prior studies have found inconsistent relationships between measures of self-concept and adolescent alcohol use. The current study explored whether the link between various measures of self-concept and alcohol use depends on gender. In addition, earlier work suggested a focus on negative self-esteem (i.e., self-derogation) might be more useful in predicting alcohol use. Students (N = 1459) attending 22 middle and junior high schools in New York City completed surveys that included measures of efficacy, self-derogation, and alcohol use. Participants completed surveys at baseline, 1-year follow-up, and 2-year follow-up. Data collectors administered the questionnaire following a standardized protocol during a regular 40-min-class period. On the basis of a longitudinal structural equation model, lower efficacy was related to greater self-derogation a year later across gender. Increased self-derogation predicted higher alcohol use for girls but not boys. These findings are congruent with a literature highlighting the importance of negative thoughts about the self in drinking behavior for women but not men. The results suggest that the alcohol prevention approaches should include material to enhance girls' self-esteem.  相似文献

This study examined the nature and correlates of different patterns of perceived control in adolescents' relationships with their best friends. Participants included firstborn adolescents (M = 14.94 years), their younger siblings (M = 12.44 years) and both their mothers and fathers in 163 families as well as a best friend of each adolescent (M = 15 years). Data were collected from family members during home visits regarding adolescents' family relationships, friendships, and psychosocial adjustment; time use data were gathered during a series of 7 nightly phone interviews. Information was obtained from best friends during a brief phone interview. We developed a typology of 3 different patterns of perceived friendship control based on the combination of adolescents' and their best friends' ratings of relational control. Patterns of control in adolescents' friendships were associated with the distribution of control in both parents' marriages and adolescents' sibling relationships. Further analyses, designed to test developmental predictions, revealed connections between friendship control and other qualities of adolescents' friendships (i.e., intimacy, conflict, perspective-taking).  相似文献

The thaw of the Cold War ended the chess game between the superpowers and seemingly gave new momentum to the revival and spread of liberal democracy and its corollary, capitalism. Just as missionaries once offered Christianity to "save" colonised peoples, democracy has become the new gospel promising "salvation". Both donor and recipient countries appeal to democracy, hoping that it will reverse decades of misfortune. Donor nations and multilateral financial institutions preach democratic governance. "Born again democratic" national leaders in the South who are intent on clinging to power attend to their sermons. None appear to have a genuine faith in democracy. While some nations and NGOs do give altruistically, most use foreign aid as another means of pursuing their national interest. Democracy is an elastic concept. Indeed it seems, at least at this point, that the new gospel of democracy is but a convenient tool used by different players for they own selfish reasons.  相似文献

Evidence from a University of Zimbabwe oral history project suggests that many rural women in colonial Rhodesia played an active role in undermining patriarchal customs which they experienced as oppressive. These women defied family norms by choosing their own marriage partners, prioritizing the formal education of their daughters and finding ways to generate income to secure greater degrees of autonomy. This study compliments other research which depicts women's primary form of resistance to be moving from rural to urban areas, by showing what options some women exercised while remaining within rural society.  相似文献

Outsourcing of risk management activities is a well-established practice, involving a range of services from actuarial audits to loss control training to risk financing management to claims administration services. Surprisingly, little work has been done to examine the risks associated with outsourcing risk management activities. This article examines the outsourcing of claims management services by reviewing the research on outsourcing risks and by interviewing leading practitioners. In doing so, the authors draw some provisional observations about risks and risk costs associated with outsourcing claims management services—observations that seem generalizable to all risk management outsourcing.  相似文献

The size of the Pareto set in the issue space of spatialvoting models is a function of the tax prices that voters arecharged. When all voters pay Lindahl prices for all goods, thePareto set collapses to a single point. The Pareto set can beenlarged by altering tax shares so they are further fromLindahl prices, and can be reduced by moving toward Lindahlpricing. A smaller Pareto set moves voters closer to consensuson issues, so reduces political decisionmaking costs and makesthe political system more stable.  相似文献
