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

Policies are implemented in complex networks of organizations and target populations. Effective action often requires managers to deal with an array of actors to procure resources, build support, coproduce results, and overcome obstacles to implementation. Few large-n studies have examined the crucial role that networks and network management can play in the execution of public policy. This study begins to fill this gap by analyzing performance over a five-year period in more than 500 U.S. school districts using a nonlinear, interactive, contingent model of management previously developed by the authors. The core idea is that management matters in policy implementation, but its impact is often nonlinear. One way that public managers can make a difference is by leveraging resources and buffering constraints in the program context. This investigation finds empirical support for key elements of the network-management portion of the model. Implications for public management are sketched. 相似文献

Desperately Seeking Selznick: Cooptation and the Dark Side of Public Management in Networks 总被引:1,自引:0,他引:1
Most literature on public-sector networks focuses on how to build and manage systems and ignores the political problems that networks can create for organizations. This article argues that individual network nodes can work to bias the organization's actions in ways that benefit the organization's more advantaged clientele. The argument is supported by an analysis of performance data from 500 organizations over a five-year period. A classic theoretical point is supported in a systematic empirical investigation. While networks can greatly benefit the organization, they have a dark side that managers and scholars need to consider more seriously. 相似文献

This paper investigates the impact of fiscal institutions on state government borrowing costs. We find that institutions have both a direct and indirect effect on interest costs paid by state governments. Revenue limits are associated directly with higher interest costs; expenditure limits, stricter balanced budget rules, and restrictions on state debt issuance are indirectly associated with lower interest costs because they lead to higher credit ratings. It appears that investors and bond raters incorporate information on fiscal institutions into their assessment of state government credit quality. 相似文献
