This research examined the “mental health literacy” of adolescents concerning eating-disordered behavior. A vignette describing
a fictional 16-year old female meeting diagnostic criteria for bulimia nervosa was presented to 522 female high school students,
followed by a series of questions concerning treatment of and treatment-seeking for the problem described. Results indicated
that primary care practitioners, mothers and close female friends were most highly regarded as potential sources of help.
Self-help interventions, including the use of vitamins and minerals, were also highly regarded, whereas participants were
less positive about the benefits of mental health specialists and ambivalent about the use of anti-depressant medication.
Most participants believed that the problem described would be difficult to treat, and that relapse was likely even given
appropriate treatment. An additional finding of note was that among participants with a high level of eating disorder symptoms
(n=36, 6.9%), recognition of an eating problem was poor. We conclude that beliefs likely to be conducive to low and/or inappropriate
treatment-seeking for eating problems may be common among adolescent girls. In addition, the findings suggest that prevention
programs for the eating disorders need to target not only at-risk individuals, but also individuals in their immediate social
environment. 相似文献

A minimax procedure for electing committees 总被引:1,自引:0,他引:1
A new voting procedure for electing committees, called the minimax procedure, is described. Based on approval balloting, it chooses the committee that minimizes the maximum Hamming distance to voters’ ballots, where these ballots are weighted by their proximity to other voters’ ballots. This minimax outcome may be diametrically opposed to the outcome obtained by aggregating approval votes in the usual manner, which minimizes the sum of the Hamming distances and is called the minisum outcome. The manipulability of these procedures, and their applicability when election outcomes are restricted in various ways, are also investigated. The minimax procedure is applied to the 2003 Game Theory Society election of a council of 12 new members from a list of 24 candidates. By rendering outlying voters less influential and not antagonizing any voters too much, it arguably would have produced a committee more representative of the interests of all voters than the minisum committee that was elected. 相似文献

Identity Salience, Identity Acceptance, and Racial Policy Attitudes: American National Identity as a Uniting Force 总被引:1,自引:0,他引:1
John E. Transue 《American journal of political science》2007,51(1):78-91
Political science has paid a great deal of attention to sources of intergroup conflict, but the discipline has focused less on forces that bring people together and lead them to transcend group boundaries. This study presents evidence that attachment to a shared superordinate identity can improve intergroup relations by reducing the social distance between people of different racial groups. Using a survey experiment, this research shows that making a superordinate identity salient increased support for a tax increase. The effects of the identity salience treatment are compared to a policy particularism treatment in terms of effect size and their interaction with each other. The size and direction of the identity salience effect is affected by the degree of respondents' acceptance of the proffered identity. Implications for social identity theory, racial policy attitudes, and American national identity are discussed. 相似文献

Almost all legislators are subordinate to party leadership within their assemblies. Institutional factors shape whether, and to what degree, legislators are also subject to pressure from other principals whose demands may conflict with those of party leaders. This article presents a set of hypotheses on the nature of competing pressures driven by formal political institutions and tests the hypotheses against a new dataset of legislative votes from across 19 different countries. Voting unity is lower where legislators are elected under rules that provide for intraparty competition than where party lists are closed, marginally lower in federal than unitary systems, and the effects on party unity of being in government differ in parliamentary versus presidential systems. In the former, governing parties are more unified than the opposition, win more, and suffer fewer losses due to disunity. In systems with elected presidents, governing parties experience no such boosts in floor unity, and their legislative losses are more apt to result from cross-voting. 相似文献

We investigate the sources of an important form of social inequality: the social processes by which men and women acquire participatory resources in organizations. In particular, we investigate the extent to which men and women acquire civic skills and are targets for political recruitment within churches. Integrating theory about social interaction within an organizational structure, we hypothesize that the ways in which women gain politically relevant resources from the church are simply different from those of men. Three factors explain the institutional treatment of women in churches: (1) women's political contributions are devalued; (2) women respond to social cues more than men do; (3) women respond to political cues from clergy—especially female clergy—whereas men do not. Our findings of gender differences in civic resource acquisition provide a more nuanced treatment of the mobilization process and have broad implications for the relationship between political difference and participatory democracy . 相似文献

This essay addresses four questions by comparing the management capacities and challenges of congregations, faith‐based organizations, and secular organizations that provide human services: (1) What role, if any, do congregations and faith‐based organizations currently play in the social service delivery system? (2) Are congregations interested in changing their role in the social service delivery system? (3) Compared to faith‐based and secular organizations, do congregations have the capacity to adapt to new roles in the social service delivery system? Finally, (4) compared to faith‐based and secular organizations, do congregations have similar service capacities and management challenges? The findings indicate that although more than half of congregations already provide some type of health or human services, they provide a narrower range of services, consider these services a lower priority, and seem to encounter more extensive management challenges than faith‐based and secular organizations. 相似文献
