This multisite assessment of five, court-affiliated parent education programs incorporates information from 3,000 exit surveys by attendees, 602 telephone interviews with willing parents six months later, comparisons with 145 divorcing parents who did not attend a program, and reviews of court activity. Parents report high levels of satisfaction with the programs and credit them with helping to sensitize them to their children's needs and making visitation more successful and enjoyable. Although attendees report better compliance with divorce decrees, comparable proportions of parents in treatment and comparison groups report conflict over child custody and access, and a review of court files shows identical litigation patterns for both groups over a four-year period of time .  相似文献

This study examines the association of self-perceptions with sixth to eighth graders' exposure to mixed-sex and dating contexts. It contrasts two hypotheses: the stress hypothesis, which suggests that the transition to romantic relationships will be associated with declines in self-esteem, especially for girls, and the leisure hypothesis, which suggests that movement into a desired role in an emotionally positive social context will be associated with positive emotions and higher self-esteem. Results indicate that adolescents experience mixed-sex settings positively, and that comfort with the other sex (for girls) and more time spent with the other sex (for boys) are predictive of more positive self-perceptions. Activity diary data suggest that these differences are due to differences in the emotional climate of same- and mixed-sex settings, rather than to the activities adolescents engage in with same- and mixed-sex groups. Dating boys who are less interested in dating experience lower self-esteem. Results are discussed in light of the transitional nature of mixed-sex relationships in early adolescence and the preparatory role played by same-sex friendships.  相似文献

Ethical challenges in public health can have a significant impact on the health of communities if they impede efficiencies and best practices. Competing needs for resources and a plurality of values can challenge public health policymakers and practitioners to make fair and effective decisions for their communities. In this paper, the authors offer an analytic framework designed to assist policymakers and practitioners in managing the ethical tensions they face in daily practice. Their framework is built upon the following set of six considerations: determining population-level utility of the proposed action; demonstrating evidence of need and effectiveness of actions; establishing fairness of goals and proposed implementation strategies; ensuring accountability; and, assessing expected efficiencies and costs associated with the proposed action. Together, these considerations create a structured guide to assist decision-makers in identifying potential ethical challenges and in assessing the moral considerations that underlie public health practice - and possibly even, if the conditions are met, reduce the creation of ethical tension. Although the authors'empirical experiences provide the basis for the framework advanced here, their approach remains to be tested and evaluated by public health practitioners.  相似文献

This paper examines race-based peremptory challenges. Such challenges occur during the voir dire jury selection process. The process allows both the defense and the prosecution to strike jurors who they believe will not decide cases fairly. However, in the case of Batson v. Kentucky 476 U.S. 79 (1986), the Supreme Court ruled that race could not be used as a factor in eliminating prospective jurors. This paper examines federal litigation for five years in which it was alleged that race was used as a factor in removing a juror. An examination of the cases revealed that most of the cases involved sole male litigants who allege that there were multiple race-based peremptory challenges used in their cases. Moreover, most of the cases that led to the allegations involved violent offenses. Other case characteristics are noted, but of most significance was the finding that most appellants lost their cases. As such, the courts felt that most of the challenges were, in fact, race neutral. The implications of this research are discussed. This study was funded by an undergraduate research grant from Penn State University.  相似文献

Members of married couples rated how ideal communal, exchange, and equality rules were for their marriages. They also reported on whether they and their spouses followed each norm in general in their marriages and in the domains of housework and child care. Both men and women considered a communal norm to be more ideal than the other norms and reported that they and their spouse followed a communal norm to a greater extent than an exchange or equality rule, both in general and in the domains of housework and child care. In addition, links between reports of actual division of labor in each domain, as well as reports of norm use, and perceived fairness of the division of family work were examined. Greater inequalities in the division of labor were linked to decreased perceptions of fairness. Controlling for reports of division of labor, women's reports of the self and of the spouse following a communal norm were linked with increased perceptions of fairness as were women's reports of the spouse following an equality rule. In contrast, and again after controlling for reports of division of labor, women's reports of the self following an exchange rule and men's reports of the self and of the spouse following an exchange rule were associated with greater perceived unfairness of the division of family work.  相似文献
