(We are attempting to inaugurate a different type of questions and answers page in this issue of the American Statistician. Our purpose is to stimulate an interest in conceptual and measurement problems which arise in the course of statistical work and which require discussion apart from purely mathematical considerations. It is hoped that our readers will find this approach of interest and value. We are inviting questions of this type.)  相似文献

The captains of the health care industry are leading a transformation in health care. Increasing numbers of physician executives are acquiring the knowledge, skills, and attitudes essential to both the science and the art of management. If they wish to practice the art of management at a high professional level, however, physician executives must be willing to experiment with their behavior in interactions. Change and growth in this aspect of human nature will also bring them face-to-face with their self-images. More important, attention throughout an organization to behavior toward one another will have a significant bearing on the quality of the organization's services to clients.  相似文献

Paraphilic disorders are psychiatric syndromes primarily characterized by deviant sexual thoughts, cravings, urges, and/or behaviors. Paraphilic men may engage in inappropriate sexual behaviors when cravings for socially unacceptable sexual acts become overpowering. These often chronic disorders may not only cause emotional distress and social embarrassment to the afflicted patient but also to the targets of their paraphilic focus. The primary objective of this article is to examine and review data on the efficacy and tolerability of the testosterone-lowering agents medroxprogesterone acetate, cyproterone acetate, and leuprolide acetate. The secondary goal is to review data on less conventional and more innovative pharmacological treatments, particularly the serotonin-specific reuptake inhibitors.  相似文献

This article describes the Durham Family Initiative (DFI), an innovative effort to bring together child welfare and juvenile justice systems to reach DFI's goal of reducing the child abuse rate in Durham, North Carolina, by 50% within the next 10 years. DFI will follow principles of a preventive system of care (PSoC), which focuses on nurturing the healthy parent-child relationship. A community collaborative of government agency directors has signed a memorandum of agreement to implement the PSoC principles. The researchers will use multiple methods to evaluate DFI's efficacy.  相似文献

The authors provide examples of sports-based youth development programs and offer information about program mission and vision, program design and content, evaluation results, and program sustainability. The four sports-based youth development programs presented are Harlem RBI, Tenacity, Snowsports Outreach Society, and Hoops & Leaders Basketball Camp. These programs serve diverse audiences with diverse missions, but all are focused on using sports to develop life skills and facilitate learning. Harlem RBI serves boys and girls ages seven to eighteen living in East Harlem. The program combines baseball, academic, and enrichment programs with the overall goal that participants who enter the program as vulnerable children graduate as resilient young adults. Tenacity, a nonprofit organization with headquarters in Boston, uses tennis to attract and retain students who particiate in a high-quality academic support and physical fitness program. The mission of Snowsports Outreach Society, based in Vail, Colorado, is building character in at-risk and underprivileged youth to develop their decision-making ability for healthy and successful life experiences. Hoops & Leaders Basketball Camp is a youth mentoring and leadership development program that offers summer camp experiences to improve the lives of at-risk urban youth in New York City. It uses the game of basketball to provide youth with caring mentors, develop leadership skills, and offer exposure to different educational and career paths.  相似文献
