The authors conducted a 10-year follow-up study using a telephone survey to investigate the availability of emergency contraceptive pills (ECPs) at college health centers in the mid-Atlantic region of the United States. They also examined related issues, such as distribution procedure, existence of a written protocol, personnel involved, contraindications, follow-up procedures, methods of advertising, staff attitudes, changes in distribution over the past 10 years, and availability if ECPs become over-the-counter. Of the 119 completed responses, 58 schools (49%) reported distributing ECPs. The most common reasons schools listed for not distributing ECPs (n = 61, 51%) were religious convictions, understaffing, and lack of funding. Major changes in ECP distribution over the past 10 years related primarily to the number of schools distributing ECPs, protocol in ECP distribution, and advertising for ECP services.  相似文献

The field of positive youth development has expanded focus from articulating and measuring desired manifestations of positive well-being to assembling the environmental conditions known to promote these desired outcomes. Evidence of the effectiveness of community-level efforts promoting positive youth development is still emerging, in particular theory-driven examples of community-driven youth development. This study examined the Community Action Framework, one theory-based community youth development model, through the experiences of the Ready by 21 Austin/Travis County coalition (RB21). The coalition connects youth-serving organizations and also regional coalitions, while promoting the positive development of area youth. Participant observation, interviewing, and archival strategies were integrated to capture information related to the complex and dynamic coalition. Results indicated that RB21 represents a practical and meaningful application of the Community Action Framework. Specific examples and recommendations are provided as guidance for other community level youth development efforts.  相似文献

The decision to dismiss a coach is challenging because poor performance tends to coincide with both bad luck and low coaching ability. We differentiate between dismissals following actual poor performance on the pitch (wise dismissals) and dismissals following seemingly poor performance due to bad luck (unwise dismissals). To categorize dismissals, we use “expected goals,” which are less vulnerable to random variation in match outcomes. Using data from European football, we find that wise dismissals increase subsequent performance compared to a control group of nondismissals with similarly poor performance on the pitch. However, unwise dismissals do not improve subsequent performance compared to a control group with similar strings of bad luck. (JEL D81, J44, L83)  相似文献

This introduction begins with memories of homophobia the editors experienced to remind the reader of the general climate old lesbians faced in their younger years. Rationale for studying old lesbians and the relevance of the articles contained in this issue are described. Some different ways old lesbians identify that may affect policy decision and research analysis are included. Early significant research on the topic of old lesbians is noted and suggestions for future research studies are recommended.  相似文献

The study presented here analyzed the patterns of demands made on 66 middle-aged women by their elderly parents and their adult children who were living at home. Factor analyses of the reports of family interactions revealed the presence of five adult children-middle-aged parents interaction factors and four elderly parents-middle-aged parents interactions. These patterns were considerably more complex than previous studies of the Sandwich Generation suggested. As expected, socioeconomic status and health of the elderly parents were related to these family interaction factors.  相似文献

Prior sensitivity analysis and cross‐validation are important tools in Bayesian statistics. However, due to the computational expense of implementing existing methods, these techniques are rarely used. In this paper, the authors show how it is possible to use sequential Monte Carlo methods to create an efficient and automated algorithm to perform these tasks. They apply the algorithm to the computation of regularization path plots and to assess the sensitivity of the tuning parameter in g‐prior model selection. They then demonstrate the algorithm in a cross‐validation context and use it to select the shrinkage parameter in Bayesian regression.
