This article examines the relationship between personal discount rates and sexual behaviors in a sample of teenagers and young
adults. We find that higher discount rates (an indication of less willingness to forego current consumption for future consumption)
are significantly associated with a range of sexual behaviors, including ever having sex, having sex before age 16 years,
and past or current pregnancy. These associations are consistent with previous studies showing a link between discounting
and other, non-sexual health behaviors.

After defining the complementary relation R of a binary relation R on a set X, this paper constructs the binary relation C (is a complementary property of) on the set P of nine well known elementary properties that R might possess. It deduces some theorems about C; especially that symmetry is the only one of these possible properties of R on X that is possessed by C on P. The set P may be enlarged to contain other elementary properties of R on X without changing the truth of these theorems, when the symbols of sets are properly modified. Finally, the paper discusses the desirability of a general theory of elementary properties of binary relations for the further development of statistical decision theory. 相似文献

Risk and its Management in Post-Financial Crisis Hong Kong 总被引:1,自引:0,他引:1
Raymond K. H. Chan 《Social Policy & Administration》2006,40(2):215-229
In the 1970s and up until the financial crisis occurred in the late 1990s, Hong Kong prospered in a relatively stable social, economic and political context. Since the financial crisis, however, its population has been increasingly exposed to risk: there has been job uncertainty and decreasing capacity for self‐reliance, leading to a growing reliance on public welfare and on families at a time when both are under pressure. The old welfare policies, unable to cope with the new risks, have been replaced by neo‐liberal reforms, redistributing the roles and responsibilities of the individual and the state, with a greater burden falling on the former. Individuals are required to be prudent to manage risk. While these reforms have relieved some of the burden on the state, both new social risk groups and ‘net taxpayers’ considered themselves to have borne disproportional costs. Society is facing serious problems resulting from ineffective old welfare policies, new social risks due to new policies, and the political upheavals arising from increased social conflicts and weakened social cohesion and solidarity. A further complication is that there is no acceptable platform or agent to negotiate a compromise between the polarized groups. This article argues that reliance on publicly funded risk coping strategies or on neo‐liberal risk prevention and mitigation strategies is not a desirable and sustainable policy. A commonly accepted political platform is required to negotiate a compromise which emphasizes shared and balanced roles and responsibilities, and a well‐conceived combination of risk prevention, mitigation and coping strategies. 相似文献

古典管理理论主要包括韦伯的科层管理、泰罗的科学管理和法约尔的一般管理原理。其贡献在于 :突出了管理中采用科学方法的重要性 ;指出坚持学习会不断地改善工作方法 ;确定了在组织有效运作中的许多重要原则 ;强调了薪金作为激励因素的潜在重要性。本文同时对古典管理理论进行了批判性的反思 :首先 ,认为高效率的组织都具有类似的、可普遍适用于所有组织的管理原理 ,即存在组织管理的“最佳途径”是脱离现实的 ;其次 ,古典管理理论假设人都是“经济人” ,而忽视了其它使管理有效的因素 ;最后 ,官僚制并非是计划、组织和协调最好的组织结构。 相似文献

In this article, we predict and find that self-perceptions of environmentalism are changed by subtle manipulations of context and, in turn, affect environmental behavior. In Study 1, we found that people exhibit greater positive assessments of their environmental behaviors (1) in the context of denying harm to the environment than in the context of claiming to help the environment, and (2) in situations where behaviors are evaluated subjectively than in situations where behaviors are evaluated more objectively. In Study 2, we explored the relationship between self-perceptions of environmentalism and environmental behaviors. Our data suggest that environmentally friendly behaviors may be promoted by leading people to perceive themselves as good environmentalists. 相似文献

Objectives. Harris and Sim (2002) recently demonstrated the complexity of lived race by exploring patterns of racial self‐identification. They raised important sociological questions about the role of context in racial self‐identification, but offered an incomplete picture of ethnic fluidity by excluding Hispanics from their analyses. We address this limitation with data on Hispanics from the National Longitudinal Study of Adolescent Health (Add Health). Methods. Our social‐psychological approach, using compositional analysis, focuses on the lived experience of race and ethnicity as qualitatively similar conceptual categories. Results. Informed by the cognitive process of social categorization, we find that considerably more individuals show fluidity in racial and ethnic self‐identification across contexts than suggested by Harris and Sim. Conclusions. Harris and Sim's thesis is even more strongly supported by these findings than in their original analysis, and our findings reinforce their challenge to the assumed stability of racial and ethnic measurement in sociology. We conclude by proposing a change in the measurement of race/ethnicity in America. 相似文献

The article presents the beginning of a discussion on how the doctrine of confidentiality may have been misapplied in the area of children's protective services. It asks the reader to consider who the client is in these cases and, having answered that question, asks what is the professional responsibility? The whole discussion is linked to the difficulties in dealing with media attention in these cases and offers some experience in the form of case examples. Woven in to the matrix of the above discussion is a clinical and public educational discussion. Preserving confidentiality in its traditional sense can contribute to a preservation of the family secret, namely, child abuse. In that way, a child protection agency can actually be contributing to the maintenance of abuse patterns in a family. Also, with no capacity to speak professionally about specific abuse, the public education impact is diminished. 相似文献
