Clinic-based distribution of contraceptive commodities is expensive per unit distributed. This situation has fueled the search for alternative means of delivery. Comparing the performance of alternatives is straightforward if the output measure is a count of commodities distributed, but comparing actual fertility impacts is another matter. I use data from the 1991 Indonesia Demographic and Health Survey to assess the extent of difference among the eventual fertility outcomes of users supplied with similar commodities through varying sources. When the “modern” methods of pill, IUD, and injection are grouped together, the fertility of users supplied with these commodities differs markedly according to their source of supply. I find little evidence for self-selecting of users into supply channels. This result implies that fertility differentials by source are likely due to characteristics of the distribution channels.  相似文献

The purpose of this study was to examine outcomes for students enrolled in two teen pregnancy prevention programs: the Youth Asset Development Program (YADP); and the Postponing Sexual Involvement Program (PSIP) and identify possible areas for program refinement. The study design consisted of two sets of comparisons: (a) sixth-grade students who completed the PSIP versus the control school; and (b) the YMCA Success Centers where the YADP was introduced versus the control school. Two hundred thirty-seven students were selected to participate in the study. Students who participated in the prevention programs had significantly (p < .05) higher academic achievement, participation in school related activities, and enjoyed school much more than students from the control school. However, no statistically significant differences were found between program participants and the control group when they were compared on personal orientation and judgments about teenage parenthood. Implications for program modification and program effectiveness are discussed.  相似文献

Although family therapists often include children in therapy sessions, they rarely consider the child's wishes regarding participation or ask children for their impressions of therapy. In this study, 16 children between the ages of 5 and 13 who had participated in at least four family therapy sessions were interviewed to determine their perspectives on the experience. The children made it clear that they wished to be involved in a meaningful way in therapy and that they wanted to come to sessions even when they were not the focus. Feedback from these children is used to suggest ways family therapists might enhance their effectiveness with families with children.  相似文献

I describe how developments over the past 25 years in computing, funding, personnel, purpose, and training have affected academic statistical consulting centers and discuss how these developments and trends point to a range of potential futures. At one extreme, academic statistical consulting centers fail to adapt to competition from other disciplines in an increasingly fragmented market for statistical consulting and spiral downward toward irrelevancy and extinction. At the other extreme, purpose-driven academic statistical consulting centers constantly increase their impact in a virtuous cycle, leading the way toward the profession of statistics having greater positive impact on society. I conclude with actions to take to assure a robust future and increased impact for academic statistical consulting centers.  相似文献

In this paper the use of three kernel-based nonparametric forecasting methods - the conditional mean, the conditional median, and the conditional mode -is explored in detail. Several issues related to the estimation of these methods are discussed, including the choice of the bandwidth and the type of kernel function. The out-of-sample forecasting performance of the three nonparametric methods is investigated using 60 real time series. We find that there is no superior forecast method for series having approximately less than 100 observations. However, when a time series is long or when its conditional density is bimodal there is quite a difference between the forecasting performance of the three kernel-based forecasting methods.  相似文献

Sociologists have done important research documenting the key role that think tanks play in the climate change denialism movement in the United States, which has sought to mislead the American public about the realities of global warming. Sociologists have not, however, assessed the full range of ways that think tanks are responding to – or planning for – global environmental change. This article proposes a typology of elite responses to global warming, which goes beyond denialism to include (i) limited climate mitigation, (ii) climate adaptation/privileged accommodation, and (iii) climate opportunism. Ultimately, this article provides insights on ways to build upon previous research in both environmental and political sociology to study the interface between elite‐driven policy, climate change, and capitalism.  相似文献

Very little is written in the literature by or about clinicians providing psychotherapy in prison. This article will examine psychotherapy in prison through the criteria of Langs’ (Psychotherapy: A basic text. Northvale, NJ: Jason Aronson) therapeutic frame. These criteria include: stability and neutrality of the therapeutic setting, therapist anonymity, fee consideration, and confidentiality. I will use my experiences from various prison settings to examine similarities and differences between psychotherapy inside and outside prison.I wish to thank Drs. Jacqueline Helfgott, David Lovell and Lorna Rhodes for their generous time and suggestions toward making this, originally lengthy article, manageable and readable. I am solely responsible for whatever shortcomings remain.  相似文献
