The authors examine whether the concept of social capital can facilitate our understanding of online networks in development. Much of the knowledge generation and social learning in development takes place in networks, which increasingly operate online. Although these networks are assumed to be a positive force in development, there are many unknown factors, partly because they are in their infancy. The concept of social capital has traditionally been applied to examine the functioning of groups and societies. More recently, it has also been applied to development and to online networks outside development. Three non-development approaches to examining social capital in online networks and communities are reviewed in the article. Elements of these approaches, combined with development-related aspects, are used to produce a framework to facilitate the analysis of social capital in online networks in a development context. 相似文献

This article reports on an exploratory study of ethical reasoning among public administrators in Russia. Survey interviews and focus group follow-ups with civil servants participating in graduate training programs at the Russian Academy of Public Service provide information about their preferred mode of ethical reasoning; the demographic, attitudinal, organizational, and professional factors associated with that reasoning; and the behavioral choices implied. Using a sample of 113 public officials who represent a broad spectrum of regions in Russia, this study assesses moral reasoning, examines variables associated with alternative models, and compares these responses with findings from studies conducted in Poland and the United States. Based on this exploratory study, we suggest implications for theory, research, and practice. 相似文献

This research tests the possibility that the reasonable woman as compared to the reasonable person test of hostile work environment sexual harassment interacts with hostile and benevolent sexist beliefs and under some conditions triggers protectionist attitudes toward women who complain of sexual harassment, We administered to a sample of undergraduates the ambivalent sexism inventory along with the fact patterns in two harassment cases and asked them to make legally relevant decisions under either the reasonable woman or person standard. We found that those high in hostile sexism, and women, found more evidence of harassment. However, those high in benevolent sexism did not exhibit the hostile sexism effects. Although men were less sensitive to the reasonable woman standard than women, under some conditions the reasonable woman standard enabled both genders to find greater evidence of harassment. The results are discussed from the perspectives of law and psychology. 相似文献

This study describes the Supervised Access Pilot Project, implemented in 14 locations in Ontario, from the perspective of those offering the service and community organizations whose members use the service. Two services were offered: visits and exchanges. The average cost of a visit varied considerably across centers (range $15 to $309), a result that is partly attributable to economies of scale. Centers in large urban centers were more cost-efficient than those situated in small communities. Centers provided neutral and safe circumstances for visiting. Only 1.6 serious rule violations occurred during every 1,000 visits. It was estimated that about 3 out of every 10,000 persons used the service. Intake and safety procedures, essential to the smooth running of the centers, have been outlined. Staff fell that they would benefit from increased training in the areas of conflict resolution and the effects of divorce on family members. 相似文献
