Two cross-sectional studies investigated media influences on adolescents’ substance use and intentions to use substances in
the context of exposure to parental and peer risk and protective factors. A total of 729 middle school students (n = 351, 59% female in Study 1; n = 378, 43% female in Study 2) completed self-report questionnaires. The sample in Study 1 was primarily African-American
(52%) and the sample in Study 2 was primarily Caucasian (63%). Across the two studies, blocks of media-related cognitions
made unique contributions to the prediction of adolescents’ current substance use and intentions to use substances in the
future above and beyond self-reported peer and parental influences. Specifically, identification with and perceived similarity
to media messages were positively associated with adolescents’ current substance use and intentions to use substances in the
future, and critical thinking about media messages and media message deconstruction skills were negatively associated with
adolescents’ intention to use substances in the future. Further, peer influence variables (e.g., peer pressure, social norms,
peer substance use) acted as risk factors, and for the most part, parental influence variables (e.g., parental pressure to
not use, perceived parental reaction) acted as protective factors. These findings highlight the importance of developing an
increased understanding of the role of media messages and media literacy education in the prevention of substance use behaviors
in adolescence. 相似文献

Principal-agent theory alerts principals to their problematic relationship with agents. The former are encouraged to take deliberate action to counter asymmetries in knowledge, moral hazard etc. To avoid this, principals should determine outcomes and contracts and incentives should be designed to achieve them. This approach has influenced the form of purchaser-provider arrangements, including the Job Network. This article reviews impacts, which include incentives for gaming and increased transaction costs. Another survey highlighted the extent to which innovation in the disability employment sector had depended on collaboration, which competition would end. The article then sketches an alternative pragmatic or experimental approach, which assumes that the centre can never establish outcomes that are other than provisional and corrigible. Program design needs to be built around this fundamental fact. Learning not 'carrots and sticks' is the appropriate form of relationship. The article explores the feasibility of this approach in a Job Network context . 相似文献

Eighty college males were given an expanded identity status interview which included two new interpersonal-sexual areas, “attitudes towards sexual expression” and “sex-role beliefs.” The relative contribution of the new content areas as well as of the standard three areas (occupation, religion, and politics) to overall identity status was assessed by noting the extent of correspondence. Identity status in each content area was also compared with performance on the dependent variable of cognitive complexity. Ideology contributed more than occupation both to overall status rating, as well as to discrimination on the dependent variable. Results on the two new areas supported the view that interpersonal-sexual concerns are important for men's identity development as well as for women's. The finding that all interview areas corresponded well with overall identity status and discriminated significantly on the dependent measure leads to the suggestion that the process variables of crisis and commitment may so overshadow a particular content area that any content of personal relevance for the late adolescent might be used in investigating ego identity development. 相似文献

Despite the hypothesized propensity for shirking to marklegislative institutions, the evidence is rather equivocal;moreover, most of the research has focused exclusively onlegislator voting, thereby constraining whatevergeneralizations might emerge. The purpose of this paper is tocontribute to the debate over the question of politicalshirking by extending the range of phenomena examined toinclude congressional foreign travel. Our analysis providesevidence that opportunism is a problem in Congress. We findthat last-period problems have arisen in the area of foreigntravel, and that increased scrutiny to the problem on the partof Congress only shifted consumption patterns, i.e.,legislators began taking foreign junkets near, but not at theend of, their legislative careers. Not all foreign travelshould be construed as worthless junketing since there isstrong evidence that some foreign travel is related tomembers' responsibilities on congressional committees. 相似文献

The conversion of British trade unions to positive attitudes towards the European Community was a significant feature of British politics in the late 1980s. This article explains the origins of this policy shift and questions the received wisdom that short term opportunism was the primary motivating factor. The British trade union response to '1992' was far from uniform and distinct factions can be identified within a policy coalition. The reasons for the durability and cohesiveness of this coalition are discussed along with the general shifts in thinking on the British Left and the developments in European integration which explain the general change of attitudes. 相似文献

Japan's program for official development assistance (ODA) is a critical tool of foreign policy. However, this program has historically been driven by quantitative goals. Only in the last decade have explicit principles and implementation policies emerged that concentrate on a qualitative, more human-centered approach to ODA. According to Professor Dr. Franz Nuscheler and Ben Warkentin, Director and Research Fellow respectively of the Institute for Development and Peace, Duisburg University, Germany, this reorientation of Japan's ODA has the potential to challenge the overall stature of the country” s foreign relations. It remains to be seen, however, whether Japan's commitments to ODA reforms will be put into practice. Will Japan's ODA Charter be a tiger without teeth? 相似文献

The authors report a fatal case of a Persian leopard (Panthera pardus) attack in an animal sanctuary in Oklahoma. The victim was a 53-year-old Costa Rican woman who was attempting to feed the animal when she was attacked and killed. Autopsy, radiography, fingerprint analysis, microbiologic cultures, and dental impressions were used to evaluate the case. These simple techniques can be applied to similar cases involving wild and domestic animal attacks. 相似文献
