This qualitative study reports on thirteen assisted living (AL) administrators' perspectives of the role and the importance of the AL social worker in addressing the unmet needs of older adults as they move and transition into AL. Participant interviews were analyzed using the constant comparative method. Administrators described 5 AL social work roles: (a) decision-making and adjustment coordinator; (b) resident advocate; (c) mental health assessor and counselor; (d) family social worker; and (e) care planner. Implications include directly examining AL social workers' views, analyzing costs and benefits of employing AL social workers, and developing social work practicum sites within AL.  相似文献

We present a unified look at myopic stability concepts for hedonic games, and discuss the status of the existence problems of stable coalition structures. In particular, we show that contractual strictly core stable coalition structures always exist, and present a sufficient condition for the existence of contractually Nash stable coalition structures on the class of separable games. We gratefully acknowledge financial support from the Alexander von Humboldt Foundation (D. Dimitrov)“by “D.

Summary Advocacy for promoting user participation in the helping processof social work has been reported in the literature since the1970s, but the practicality of the concept for different clientelesof social work has been rarely explored. This paper presentsa recent qualitative study on exploring the applicability ofuser participation in work with high-risk youth in the streetswho are usually regarded as immature and low in both self-confidenceand the ability to make the ‘right’ decisions. Thefindings of the study support the promotion of the concept ofuser participation in working with high-risk youth. Positivechanges and growth were observed among this group with the applicationof user participation in the helping process. Ways for promotingthe implementation of this concept in work with high-risk youthare suggested.  相似文献

In July 1974 the U.S. Congressional Budget Act was signed into law. This legislation was the result of a heavily fought political confrontation between President Nixon and Congress over who controlled the Federal budget. In addition to the issue of control, the Act was prompted by dissatisfaction with the procedures used by Congress to determine Federal receipts and expenditures. The purpose of this paper is to assess the impact this legislation had on the U.S. economy in its early years.The first section of the paper sets up a simple modeling framework. The model is specified so as to illustrate how a change in the budget process resulting from the Congressional Budget Act could potentially produce changes in the level of total output. This section also explains the derivation of a tax and expenditure series used in the model's empirical testing. The second section addresses some of the theoretical issues, and presents the results of simulations based on the Chase, Wharton, and Data Resources econometric models. Broad conclusions are gathered in the final section.  相似文献

Objective. This article investigates how race/ethnicity is associated with specific types of violent crime such as killings between intimates, robbery homicide, or drug‐related killings. We extend the study of the role of race and ethnicity for violence by examining five ethnic/immigrant groups, including the Mariel Cubans—a group singled out by many as particularly drug‐crime‐prone. Methods. Using 1980 through 1990 homicide data for the City of Miami, we use multinomial logistic regression to examine the association between race/ethnicity, nativity, and several types of homicide motives. Results. Contrary to popular expectations, ethnicity and immigration status rarely play a role in the types of homicide involvement of victims or violators. Incident characteristics, such as multiple offenders, or gender and age, were consistently more important influences in shaping homicide circumstances. Conclusions. The analyses revealed few significant relationships between immigration status and homicide motives, suggesting that immigrant groups like the Marielitos have more in common with native groups' experiences of criminal violence than is commonly assumed.  相似文献

This paper presents the results of a study on the impact of spirituality, religiousness, and social support on the psychological well-being among rural elderly. With a rural community sample of 215 older adults, hierarchical regression analyses found significant associations between dimensions of spirituality/religiousness, social support, and psychological well-being, with spirituality/religiousness inversely related to depression and social support, positively related to life satisfaction. Findings of this study suggest that practitioners need to develop programs or services that are congruent with religious/spiritual beliefs and practices in order to better enhance the psychosocial well-being and improve the quality of life among older persons in rural areas.  相似文献
