This article presents an overview of the Ojibwa family over the past three centuries, from early European contacts to the present. It emphasizes the extent to which Ojibwa familial relations have long been embedded in extensive networks of kin that played major roles in the family lives of individuals of all ages. The article traces the effects of historical change on the Ojibwa family and examines continuity within Ojibwa kinship relations. The changes of the last century have taken a heavy toll on these relationships, yet, where they persist or are being revived, they are sources of strength and renewal.  相似文献

This paper examines the noncustodial parent earned income tax credit (NCP EITC), a new type of credit recently enacted in New York and Washington, D.C., and proposed by Senator Bayh and then‐Senator Obama in 2007. The NCP EITC offers an earned income tax credit to low‐income noncustodial parents who work and pay their full child support. This paper provides background information about the policy and presents national estimates of eligibility and benefits for an NCP EITC under three alternative policy scenarios. It also discusses several key design and implementation issues. © 2010 by the Association for Public Policy Analysis and Management.  相似文献

Increasingly development theorists and practitioners view NGOs as catalysts of sustainable development. NGOs have been regarded as champions of democratisation and promoters of new ways of engaging in politics, with considerable influence on the development of civil society and new partnerships in environmental and social advocacy. This article analyses the ways in which Costa Rican environmental NGOs (ENGOs) engage in politics, by focusing on their perceptions of their roles in environmental governance and in representation of civil society. The results of this study suggest that the ENGOs' ways of engaging in politics differ little from traditional forms of governance, while their conceptions of engaging in politics without being political are novel. While most ENGOs had no clear conception of the stakeholders whom they were supposed to be representing, the notion of representativeness is complex and should be revisited.  相似文献

Horizontal mergers can be challenged by anti trust authorities under both the US and EU Horizontal Merger Guidelines. More horizontal mergers are unconditionally approved in the US than in the EU. EU merger policy toughened after 1998 but became more in line with US practices after 2004. Differences in merger policies between the US and the EU can be explained by a greater scope of the efficiency argument in the US. The paper argues that firms only want to merge in oligopoly, if they expect to realize substantial merger specific efficiency gains, which counterbalances the price increasing effect of merger.   相似文献
