This study examined the associations between exposure to armed conflict, perceived support, work experience, needing help, and post‐traumatic distress among Israeli social workers in foster care agencies based on Conservation of Resources theory. The study used a mixed‐methods design. Six months after the end of an armed conflict, 82 social workers responded to a web‐based questionnaire with closed‐ and open‐ended questions. Results showed that exposure to the armed conflict was moderately associated with post‐traumatic stress symptoms and functional impairment. Only the workers' perceived need for personal help (but not help for professional matters) was positively associated with their psychological distress. The qualitative analysis suggests that social workers showed strengths and wanted help mainly to improve their professional skills. Yet they also elaborated on the complexities involved in conducting their professional work, especially home visits, because such visits put their own lives in danger and meant deserting their own families. Practice implications are as follows: Foster care agencies should make greater efforts to provide knowledge and skills, support, supervision, and a “safe haven” for their workers, in the context of armed conflict.  相似文献

Using data from the college population, Pearson correlations and regression were used to examine three hypotheses. The major hypothesis was that “conformity-oriented” values are associated with college students' traditional living arrangements and family-related attitudes, while “self-directed” values are associated with nontraditional attitudes and behavior. Two other hypotheses focused on interrelationships among demographic variables, values, family-related attitudes, and living arrangements. General support was found for the major value-orientation hypothesis and mixed support for the secondary hypotheses. Comparing these findings with those of several other studies, we propose that there may be a subset of human values associated with general tendencies toward confomity and resistance to change on the one hand, and experimentation and receptivity to change on the other. A typology of such value orientations is put forward for future research in areas of sex roles, social change, sociopolitical conflict, and attitude and/or behavior change.  相似文献

Experience with this parents' group model suggests that there are a number of advantages in using a multifaceted approach when working with parents of severely disturbed adolescents. Basic support and reduction of guilt and blaming are derived from the therapeutic aspect of the group process. This is augmented by having the parents in a leadership role, in the manner of a self-help group. Bringing in educational and advocacy elements allows the group to respond directly to the parents' need for detailed, accurate information about the disorders and treatment resources for dealing with them. This approach is not designed to replace family therapy, but to provide resources and support to parents. Future research will be necessary to substantiate the clinical impression that the group is quite helpful to parents and to elucidate all the factors producing success.  相似文献

Renal disease affects 11% of people in the United States over the age of 65, not including those with diabetes or hypertension. Although glomerular disease is the most common underlying etiology of age-related renal dysfunction, the cause of glomerular disease and whether it is the only contributor to renal failure are not known. Our studies in female mice show that renal disease in the postmenopausal period is associated with progressive glomerular enlargement and scarring, as well as abnormal renal function. To study the underlying causes of aging-related glomerular disease, we isolated and characterized glomerular smooth muscle (mesangial) cells from female mice of various ages. We found that the cells from older mice exhibit a variety of phenotypic changes, including increased concentrations of p27, a protein that serves to inhibit progression from the G1 to the S phase of the cell cycle. Because the bone marrow (BM) contains mesangial cell progenitors that can transfer the donor glomerular phenotype (normal or diseased) to recipients, we exchanged BM between postmenopausal and premenopausal mice and found that aging-related glomerular enlargement and scarring are transferred to young recipient glomeruli. In addition, BM from normal, young donors led to the regression of aging-related glomerular disease in postmenopausal recipients; namely, both glomerular enlargement and scarring were reduced. Thus, aging-related glomerular disease is an entity distinct from all other causes of renal disease, is characterized by phenotypic changes in mesangial cell progenitors, and is reversible when the phenotype of the progenitors is returned to normal.  相似文献

We discuss the management of catastrophe-risks from a theoretical point of view. The concept of a catastrophe is informally and formally defined, and a number of desiderata for catastrophe-averse decision rules are introduced. However, the proposed desiderata turn out to be mutually inconsistent. As a consequence of this result, it is argued that the "rigid" form of catastrophe aversion articulated by, for example, the maximin rule, the maximum probable loss rule, (some versions of) the precautionary principle, and the rule proposed in Ekenberg et al. (1997, 2000) should be given up. An alternative form of "non-rigid" catastrophe aversion is considered.  相似文献
