Latent-variable confirmatory factor analysis was used to examine the interrelationships of depressive and anxious symptomatology and 13 measures of psychosocial functioning in a community-based sample of adolescents participating in a school-based drug abuse prevention intervention. Measures of psychosocial functioning included: cognitive self-efficacy, self-management, self-reinforcement, decision-making and problem-solving skills, interpersonal skills, social anxiety, behavioral style, risk taking, conventionality, somatic complaints, perceived tangible, and adult support. Simultaneous group comparison and nested hierarchical tests were used to statistically contrast parameters obtained from male and female models. Overall, the hypothetical constructs were statistically reliable and models were psychometrically sound. Partial factorial invariance was obtained, however, the patterns of covariation between distress and psychosocial functioning were dissimilar for male and female youth. Differences clustered around affective distress, cognitive skills, and perceived functional support. More socially anxious females perceived less social support, whereas support and anxiety were positively related among male students. Male youth with high levels of conventional behavior were also socially anxious, whereas for females this relationship was absent and nonsignificant. For both male and female students, distress was moderately and inversely related to cognitive efficacy and personal competence skills. Distressed youth were also less conventional (behavioral control) and less diligent, and were characterized by greater sensation-seeking, poorer competence, and perceived less social support, and were more socially anxious with less interpersonal skills. Findings are discussed in terms of potential contributors to gender differences in distress and psychosocial functioning and their implications for the understanding of adolescent mental health. 相似文献

Bargaining in the international arena is intrinsically positional. Negotiators are often instructed by their governments not to improvise or explore new options when they meet with their counterparts — even though the invention of additional tradeoffs or packages might well produce better results for all sides. This article describes an approach that we call parallel informal negotiation which encourages a collaborative effort between contending groups that were officially not even allowed to interact: international trade and environment policy makers. 相似文献

What should you do if finances--or geography or health plan rules--put a high-ranked hospital out of reach? Good question. Here are some answers, along with other hypothetical questions related to hospital choice, access and cost. The responses, developed with the help of medical and consumer experts, are real. 相似文献

The discussion of presidential mandates is as certain as a presidential election itself. Journalists inevitably discuss whether the president-elect has a popular mandate. Because they see elections as too complex to allow the public to send a unitary signal, political scientists are more skeptical of mandates. Mandates, however, have received new attention by scholars asking whether perceptions of mandate arise and lead representatives to act as if voters sent a policy directive. Two explanations have emerged to account for why elected officials might react to such perceptions. One focuses on the president's strategic decision to declare a mandate, the second on how members of Congress read signals of changing preferences in the electorate from their own election results. We test these competing views to see which more accurately explains how members of Congress act in support of a perceived mandate. The results indicate that members respond more to messages about changing preferences than to the president's mandate declaration . 相似文献

Sections of the cerebrum, cerebellum, and brain stem of a rugby player who died 15 hours after being tackled were stained using an immunoperoxidase technique to detect beta-amyloid protein. The sections of the pons showed axonal spheroids in the base, and those of the cerebellum showed axonal spheroids in deep white matter. The findings demonstrated axonal injury following a fall from the victim's height in a team sporting event. 相似文献

This article defines budget reform perennials at the national level as those that reoccur multiple times, with little chance of passage and little change from one iteration to the next. The literature has seldom examined proposals that do not pass or the staff effort that goes into keeping flawed proposals from passing. The article describes the sources of such proposals and what can conceivably be done to lessen the tension they cause. The research is based primarily on qualitative interviews and legislative testimony. Examples of reform perennials include biennial and capital budgeting. 相似文献
