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

We investigate the role of payoff asymmetry in laboratory prisoner’s dilemma games. Symmetric and asymmetric games are examined in simultaneous and sequential settings. In the asymmetric sequential games, we study the impact of having payoff advantaged players moving either first or second. Asymmetry reduces the rates of cooperation in simultaneous games. In sequential games, asymmetry interacts with order of play such that the rate of cooperation is highest when payoff disadvantaged players move first. 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

According to A. O. Hirschman, party members who are dissatisfied with their party's policy have two options: they can either leave the party (exit) or try to change party policy (voice). Research has shown that leadership control over policy is extremely high, leaving membership influence virtually non-existent. On that basis, exit seems the only viable membership reaction to dissatisfaction with party policy. Nevertheless, research has also shown that voice is of great importance to members; hence it is voice that will be the main focus of this article, which examines the circumstances under which party members are likely to opt for voice over exit and what factors are likely to hamper voice. Using a study of the Danish Socialist Peoples Party, the Danish Social Democrats and the British Labour Party, the article shows that despite the odds stacked against them, some party members do make use of the opportunities for voice offered by the party conference, but also that they often face significant obstacles in exercising it. 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

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

A key to the success of public organizations is their ability to identify and build capacity, particularly their distinctive competencies, in order to produce the greatest value for key stakeholders. This article grounds this proposition in the resource-based view of organizations and presents a method for identifying and making use of distinctive competencies in the form of a "livelihood scheme"—a business model appropriate for the public sector—that links distinctive competencies to organizational aspirations and goals. The case of a major public sector training and consultancy unit that is part of the United Kingdom's National Health Service is used as illustration. A number of conclusions are offered in the form of a set of propositions tied to the resource-based view and related research issues. The results contribute to both public strategic management theory and practice. 相似文献
