This article will demonstrate how schools of social work can collaborate with community agencies to provide a comprehensive and enriching educational experience for both student interns and participating agencies. An innovative partnership of a state school of social work with community agencies leading to a cutting-edge geriatric field education program is described. Case examples are used to illustrate the benefits of these partnerships, as well as challenges partners overcame in forging and sustaining partnerships. Necessary components of partnership development are detailed.  相似文献

Objectives. Many cities in the United States have undergone or are undergoing racial transition from a majority white to a majority black population. Accompanying this is a change in the racial makeup of elections and officeholders. This article seeks to explain racial patterns in voter roll‐off as a city undergoes racial transition. Methods. Using a fixed‐effects regression model, we analyze the level of voter roll‐off (from the top‐of‐the‐ballot mayoral contest) among black and white voters across Memphis City Council elections, from 1967 through 2003. Results. The level of voter roll‐off among racial groups is sensitive to the racial aspect of political change. Black voters are most likely to continue to vote in council contests when there is a racial choice among candidates, when blacks have previously been elected, and when blacks occupy the mayoralty and a majority of council seats. Whites are most likely to vote in racially competitive council contests, as well as when there are a large number of white candidates, and when whites hold a majority of the council seats. Conclusions. In settings such as Memphis, where race has played a pronounced historic role, the racial context of political empowerment has a strong influence on electoral participation. Elections below the top‐of‐the‐ballot become more salient, and political efficacy grows among racial group members when that cohort occupies institutional positions, particularly the majority of positions in a governing institution.  相似文献

This article shows how time works against parents with learningdifficulties in the child protection system and Children Actproceedings. The prevailing wisdom, embedded in policy and theliterature, is that delay in care cases is bad for the childand may jeopardize his or her future. This paper shows how thepressure to avoid delay might itself be harming some families,especially parents with learning difficulties. Drawing on interviewswith social work practitioners undertaken as part of a largerstudy, the authors describe the various forms of temporal discriminationthat impact on this group of disabled parents. They concludethat procedural time limits make it harder for parents withlearning difficulties to meet the standards and expectationsenforced by Children’s Services and the courts.  相似文献

This paper explores the political significance of Asian American campaign finance activity in municipal elections. We examined both the donation patterns of Asian contributors and the fundraising coalitions assembled by Asian candidates. From the contributor perspective, we found that Asians contributed in roughly proportional levels to their population as a whole, and were willing to contribute not only to coethnics but also to Asian candidates of other ethnicities and to non-Asians. As for Asian candidates, we found that they relied heavily on Asian contributors for campaign funds, especially coethnics. Asian candidates’ ability to draw on ethnic networks for campaign funds is an important political resource that enhances their ability to mount competitive campaigns. However, the value of these networks is limited by candidates’ inability or unwillingness to form panethnic fundraising coalitions.  相似文献

Objectives . Property rights are central to debates about natural resource policy. Governments traditionally have been seen as the appropriate custodians of natural resources for their citizens. More recently, many argue the privatization of property rights will ensure that users have incentives to manage their resources well. Common property, to the extent it is discussed at all, is seen as leading to the tragedy of the commons. We evaluate these claims by assessing property rights and forest conditions in two private and three communal forests in Guatemala. Methods . Data on biological and social phenomena from five forests (151 plots) and their associated communities were collected using the International Forestry Resources and Institutions Research Program protocols. Ordinary least squares regression was used to analyze four models. We examined t -scores for differences in coefficients for the different models. Results . The models demonstrate that de jure property rights are not a powerful predictor of variations among the sampled forests. Conclusions . We argue that de facto institutions and their enforcement are much more important than de jure property rights to forest management. Communities holding a forest in common can, under certain circumstances, create institutions to manage their resources as successfully as—or more successfully than—private owners.  相似文献

In order to provide benefits to society, human medical trials must place subjects at risk of harm. This activity is thought to be justified in part by the consent of the subjects involved. But, studies have shown that most such consents are based on a therapeutic misconception (TM); the false belief of subjects that their researchers will act as their personal physicians (seeking their benefit and protecting them from harm), rather than placing them at risk of harm for the good of others. Toleration by researchers of the TM in their subjects is a form of "informational manipulation" that renders consent procedures disrespectful to subject autonomy. Consent obtained from subjects who labor under a TM is neither voluntary nor informed; as long as they have not been disabused of the TM, the action they take in enrolling in a trial is not the one they intend nor is it autonomously chosen. Changes in consent procedures should be adopted to ensure that all subjects are aware inter alia that (a) the health interests of future patients (as well as the researchers' and their sponsors' financial interests) may be more important to researchers than the interest of a subject in his or her health, and (b) normal subjects neither understand nor believe this when told. Close attention to the response of prospective subjects to this information should allow for the exclusion of all but the truly altruistic. However, the result of conscientious implementation of such policies would likely be that human medical research could no longer be conducted on more than a minimal level.  相似文献

Changing Chinese family patterns caused by immigration have contributed to the breakdown of traditional community and familial control in Chinese-American families. As a result, the Chinese-American elderly are faced with unique psychosocial problems that workers must consider when providing services to this population.  相似文献
