In attempting to manage their practices efficiently, doctors may not allow seriously ill patients enough time to sort out their feelings and raise important questions. What is at stake here is not information about prognosis and treatments but the very survival of the soul.  相似文献

This article describes mortality patterns for nonprofit organizations in a major U.S. metropolitan area between 1980 and 1988. Twenty percent of the nonprofits in a panel ceased operations during this period. Mortality rates were found to vary widely. In some instances, high mortality was found in parts of the sector that were growing rapidly. Overall, nonprofits that ceased to operate were younger and smaller, used fewer strategies to attract funders, and had less diversified income streams than survivors. These patterns also varied substantially. The results point to the drawbacks of using limited or commonsense information and the necessity of theory-based research.  相似文献

Changes occurring in health care demand that physicians expand their professional knowledge and skills beyond the medical and behavioral sciences. Subjects absent from traditional medical education curricula, such as the economics and politics of health care, practice management, and leadership of professional organizations, will become important competencies, particularly for physicians who serve in management roles. Because physicians occupy a central role in planning and allocating medical care services and other health care resources, they must be better prepared to work with other health care professionals to create a new civilization, even if this means leaving the cloistered domain of "physician land" to serve as interface professionals between the delivery of medical services and the management of health care. Our research findings and conclusions strongly suggest that economic, management, and leadership competencies need to be incorporated into the professional development of physicians, especially in postgraduate and continuing education curricula.  相似文献

Outdoor structured activities, such as Ropes Challenge Courses, are typically utilized as interventions for youth coming from urban settings. Evaluation of such programs is scanty at best. In this instance, the course experience is used as a prevention tool for high risk youth in a remote, rural setting of high unemployment, alcohol problems, and low income. The authors discuss the effectiveness of this approach, and the intended and unintended consequences for the rural community at large. The evaluation design relies on extensive qualitative methodology as well as quantitative methods to capture the unique nature of this rural project.  相似文献

The story of Anna O. has loomed large in psychoanalytic history, but few social workers know that the young woman, who was so influential in the development of Freud's thinking, became a pioneer social worker in Germany. The story of the transformation of the troubled young woman, who was actually Joseph Breuer's patient, is the focus of this paper. In addition, some of the facts of the case are discussed as social constructions. Anna O./ Bertha Pappenheim participated in the creation of the talking cure and eventually went on to be a leading feminist, developer of social programs for women, and social reformer.  相似文献

The phrase, the counterfinality of the practico-inert is from Sartre with reference to implications of modern technology as a shorthand for that enormous properly human and anti-natural power of dead human labor stored up in our machinery — an alienated power, which turns back on and against us in unrecognizable forms and can symbolize the massive dystopian horizon of organized crime as well as individual terrorist praxis (Jean-Paul Sartre (1948).Situations II. Paris: Gallimard).  相似文献

Immigration has long been a national and state concern. The 1989 Legalized Population Survey (LPS-1) collected data on illegal immigrants to the US who subsequently became legalized aliens under the provisions of the 1986 Immigration Reform and Control Act. These data are used in a study assessing whether undocumented male and female immigrants improve their earnings and occupational status over time and the extent of variation in occupational status and mobility by gender and region. The data indicate that both undocumented men and women, on average, improved their earnings and occupational status between their first jobs in the US and their jobs just before applying for legalization under the 1986 Immigration Reform and Control Act. However, the earnings, occupational status, and occupational mobility of men were greater than for women.  相似文献

This study examines the impact of mandatory seat belt laws on fatal and incapacitating injury rates in the states. Annual data for all 50 states for the period 1975-1991 are used. Pooled time series analysis is employed. The general conclusion that emerges from this analysis is that seat belt laws significantly impact state fatal injury rates. Primary enforcement and all-seat coverage provisions appear to be particularly effective in reducing fatality rates.  相似文献

The projected increase of people in Japan aged 75 years and older in the years to come implies the increase of the disabled elderly. Thus, the core of societal preparation for the aging of the population is generally considered to be the expansion of services for the disabled elderly. However, gerontological studies on the health status of the elderly conducted in Japan show that the prevalence of disability is quite low and even decreasing. Relative to the services for the disabled elderly, preventive services for the healthy elderly have long been overlooked. In 1994, the Metropolitan Tokyo Government organized a task force to develop a new health education program as the preventive health service for the healthy urban elderly. A preliminary plan outlining the health education program--consisting of propagation with a booklet, on-the-job training of practitioners, and development of new curricula and teaching materials--was proposed by the authors for discussion within the task force. Although the inquiry has just begun and the plan is still nascent, it seems adequate to fit the needs for preventive health services in the near future.  相似文献
