Social work education in both BSW and MSW level courses is missing vital content about end-of-life care, palliative care, and bereavement. End-of-life care training opportunities through continuing education programs have also been limited. This deficit is significant because a vast number of social workers are already confronted with end-of-life issues on a daily basis in a variety of practice settings. Through the Project on Death in America, Social Work Leadership Development Awards initiative, many programs and models for professional social work education and training in end-of-life care have been developed and are presented in this article. These include: end-of-life care courses, symposia, training manuals, certificate programs and fellowships. Although the curricula continue to be refined, many of these programs are available to practitioners to advance their knowledge and skills and their curricular models are available to social work educators for possible replication.  相似文献

While it is not possible to assert that all family treatment follows a universal and sequential pattern, commonalities can be ascertained which can help the therapist maintain objectivity and provide direction for himself and the family. Four major stages are outlined, each with several substages: 1) the preparation stage—mutual acceptance, definition of the problem, formulation of goals; 2) the transition stage—beginning actualization, crisis, reformulation and acceptance; 3) the consolidation stage—investment in the therapeutic work, working through alternatives; 4) the terminal stage—introduction to termination, defining the duration and format of the ending. Universal issues are identified, tasks for the therapist are outlined and common problems are described.  相似文献

The purpose of this paper is to discuss the importance of assessing the impact of infertility on couples/individuals and understanding the relevance of the impact in the context of psychological treatment. The assumption is that infertility can have a significant negative impact which can at least be minimized by therapeutic intervention. Three psychological-behavioral categories are posited as the result of several years work with infertile individuals/couples. Detailed case presentations of couples in each category are given so that the total impact of the crisis of infertility and the role of psychological intervention can best be understood.  相似文献

As part of its periodic re-evaluation of particulate matter (PM) standards, the U.S. Environmental Protection Agency estimated the health risk reductions associated with attainment of alternative PM standards in two locations in the United States with relatively complete air quality data: Philadelphia and Los Angeles. PM standards at the time of the analysis were defined for particles of aerodynamic diameter less than or equal to 10 microm, denoted as PM-10. The risk analyses estimated the risk reductions that would be associated with changing from attainment of the PM-10 standards then in place to attainment of alternative standards using an indicator measuring fine particles, defined as those particles of aerodynamic diameter less than or equal to 2.5 microm and denoted as PM-2.5. Annual average PM-2.5 standards of 12.5, 15, and 20 microg/m3 were considered in various combinations with daily PM-2.5 standards of 50 and 65 microg/m3. Attainment of a standard or set of standards was simulated by a proportional rollback of "as is" daily PM concentrations to daily PM concentrations that would just meet the standard(s). The predicted reductions in the incidence of health effects varied from zero, for those alternative standards already being met, to substantial reductions of over 88% of all PM-associated incidence (e.g., in mortality associated with long-term exposures in Los Angeles, under attainment of an annual standard of 12.5 microg/m3). Sensitivity analyses and integrated uncertainty analyses assessed the multiple-source uncertainty surrounding estimates of risk reduction.  相似文献

This report describes the importance of ethics training for mental health professionals working with persons infected or affected by HIV/AIDS. We first describe three major ethical dilemmas (confidentiality, duty to warn, and suicide) faced by mental health providers serving persons with HIV/AIDS, and the legal and clinical aspects of these dilemmas. We present data from the South Texas AIDS Training Project describing the types of mental health professionals who have attended workshops on ethical issues and HIV/AIDS. Finally, we report observations about the impact of the ethics training sessions on the participants' knowledge and attitudes.  相似文献

As infants form object representations, the patterns viewed on objects' surfaces may be challenging to decipher because these patterns may be created from the surface reflectance of an object (an object property) or from an external source, such as a cast shadow. We tested 7 ½-month-old infants' use of cues that specify the source of patterns seen on the surfaces of real, 3-dimensional objects to individuate those objects. Results suggest that when forming object representations based on patterns, 7½-month-olds rely heavily on temporal and depth cues to distinguish patterns inherent to the object from other types of patterns.  相似文献
