The fragmentation of a donor's foreign aid across too many recipient countries is widely believed to be detrimental to aid effectiveness. This article explores the origins of a new norm – recipient concentration – and assesses the extent to which it can be expected to improve aid effectiveness. It also examines 23 donors' actual record of country concentration, and finds that, though there are some potential explanations for donors' behaviour, their collective failure to implement country concentration has very little consequence in theory or in practice.  相似文献

During the 1960s, the new generation changed the American Creed by deemphasizing sensitivity to evidence, emphasizing feelings and deductive thought, while assuming an adversarial position against the sociopolitical order and embracing the American Black's struggle against racism. Driven by pain, fueled by fear and anger and oriented by existential values of being the Civil Rights Movement, sought to actualize political values of justice and equality. As peaceful demonstrations dwindled, violence increased, converting individual anger to social rage. Anger's cognitive structure changed the concept of society into a dichotomy of Black victims and Ulhite oppressors, forming an ethic of sensitivity with victims occupying the moral high ground. Pain and tragedy were banished from view and blamed on oppressors as individual identities divested civil traits and acquired cultural identity, disuniting the civil society. Rubbing against the American Creed, the ethic ofsensitivity produced a feeling of malaise posing a threat to mentaL health.  相似文献

ABSTRACT

Although some HIV prevention programs have been successful in helping gay and bisexual men change their sexual behaviors, rates of HIV infection continue to increase. In an attempt to address this problem, social workers need to move beyond traditional HIV prevention approaches to a psychosocial model of HIV prevention. Based on the work of previous researchers, this approach assumes that a combination of individual, psychological, and social factors contribute to risky sex in gay and bisexual men. Because social workers are trained to view problems from a psychosocial framework, they are already in a position to develop programs incorporating the psychosocial model. This article examines the psychosocial model of HIV prevention and the various psychosocial factors that may contribute to high-risk sexual behavior and concludes with examples of prevention research that have already incorporated the model.  相似文献

The distribution of ant colonies within a community is often well defined, yet this distribution can change due to changing environmental conditions, resource availability, and colony growth. In this study, structure infesting ant communities were sampled for one year within three Puerto Rican housing developments of different ages. These developments represented environments in different stages of recovery after a disturbance (secondary succession). Spatial mapping was used to plot the distribution and abundance of ant communities within these developments. At the beginning of the study, the youngest housing development (1 year since construction), had the fewest number of species present (ave. 1.6 per house). The second housing development (4 years old) had a greater number of species (ave. 2.6 per house), and a greater sampling frequency (the same species collected at multiple houses) than Site 1. The oldest development (8 years old) had both the greatest number of species (ave. 2.7 per house), and sampling frequency of the three sites. In all developments, the number of species, sampling frequency, and ant biomass increased throughout the year as colonies grew and foraging ranges expanded. It was observed in all developments, that species coexistence also increased throughout the year. As colony populations increased, there was a greater occurrence of multiple species being collected at the same sample house. In the youngest development, the two most dominant species increased in numbers during the year and began to be collected from the same sample houses. Spatial diagrams documented that multiple species in the older housing developments (later stages of succession), also shared a common distribution. Even the most dominant species (S. invicta) in all three sites, did not exclude additional species from foraging within its established range.  相似文献

All adoptions, including those facilitated by public agencies, should be evaluated for openness. Although there are no national figures related to openness in public welfare, there are indications that it is not considered in all cases. Adoption myths may be one of the reasons that adoption workers do not always assess a family's ability to maintain a more open adoption arrangement. The following study is the initial validation of a multidimensional psychometric instrument developed to measure myths as they relate to open adoption. Based on a sample of 547 university students, the results indicate very good reliability and acceptable factorial and construct validity. The instrument was designed as a training and research tool to inform child welfare personnel and policy makers of the influence of adoption-related myths on child welfare adoption practice.  相似文献

There is increasing interest in the emergence of a ‘global middle class’ in which high achieving young graduates increasingly look to develop careers that transcend national boundaries. This paper explores this issue through comparing and contrasting the aspirations and orientations of two ‘elite’ cohorts of graduates. Interviews with students at the University of Oxford, England, and Sciences‐Po, France, reveal very different ambitions and allegiances. Our Oxford respondents portray their futures as projects of self‐fulfilment as they build portfolio careers by moving from job to job and from country to country with limited social allegiances – epitomizing the nomadic worker of the transnational elite. Our Parisian respondents, on the other hand, display strong allegiances to the nation, state and civic duty. Their projects of the self involve reconciling their personal aspirations with strong allegiances to France. The paper concludes by discussing the significance of these differences. It argues that the enduring role of education in the formation of national identities should not be overlooked and that more detailed research is needed on the contextual specifity of transnationalism and the (re)production of elites.  相似文献

This paper examines the puzzling status of Buraku people in Japan through the methodological prism of historical sociology. I develop a theoretical approach that emphasizes the concept of racialization to illuminate the historical and social construction of Buraku status. I propose this approach as a complementary alternative to prior analytic perspectives. Two major perspectives have dominated research on the status of Buraku people. First, an earlier approach that focused on the legacy of caste discrimination. The second framework focuses on Buraku people as part of the struggle for universal human rights. This article raises three basic, but interrelated questions about the historical development of Buraku status in Japan. Why did the Buraku people become subject to such overt discrimination in local community life, and through government policy? How was the state involved in the social construction of Buraku people? How did the Buraku liberation struggles challenge formalized discrimination?  相似文献
