Lawyers for conservative and libertarian causes are active in organizing and mobilizing interest groups within the conservative coalition, and networks of relationships among those lawyers help to maintain and shape the coalition. Using data gathered in interviews with seventy-two such lawyers, this article analyzes characteristics of the lawyers and the structure of their networks. The findings suggest that the networks are divided into segments or blocks that are identified with particular constituencies, but that a distinct set of actors with extensive relationships serves to bridge the constituencies. Measures of centrality and brokerage confirm the structural importance of these actors in the network, and a search of references in news media confirms their prominence or prestige. This "core" set of actors occupies the "structural hole" in the network that separates the business constituency from religious conservatives. Libertarians, located near the core of the network, also occupy an intermediate position. Regression analysis of ties within the network suggests that the Federalist Society plays an important role in bringing the lawyers together.  相似文献

Criminologists have long debated the issue of how to define crime, and hence, the scope of criminological inquiry. For years, some critical criminologists have argued for expanded definitions of crime that include harmful behaviors of the state that may not be officially defined as criminal. Other critical criminologists have argued that existing legal frameworks may be used to study varieties of state crime, and that defining the harmful actions of the state as criminal is important to help mobilize public support for their control. In this paper, we first trace the historical development of these two perspectives, and then offer a tentative solution to the seeming tension between these two perspectives.  相似文献

This article explores the different and sometimes conflicting explanations of the success of the collective enterprises (town–village-enterprise) in China during the first phase of transition (1979–1995). It is argued that explanations, relying on cultural variables are not sustainable and this for two reasons. First, the importance of the collective enterprise is shrinking while the private sector is clearly on the rise. Second, other factors, referring to characteristics of the local and central political, administrative and economic environment, in which the Chinese enterprise has to (had to?) operate, provide for a sufficient explanation of the peculiar structure of the Chinese collective enterprises. These enterprises are seen as the result of ?bureau-preneurship’ because local bureaucrats were integrated in their management in order to pre-empt predatory behaviour and to facilitate the relationships with the central institutions. The article contributes to the property rights’ theory of the firm as it analyses an empirically very important case in which firms with unclear property rights and structures, apparently not conducive for incentives, might still be the most efficient option.  相似文献

The Rehabilitation Engineering Research Center on Technology Transfer (T2RERC) hosted a “State of the Science” conference in November, 2001. The conference reviewed technology transfer work within the field of assistive technology, and summarized related work in public, private and academic sectors. Invited speakers prepared papers on various topics concerning technology transfer, and related their findings to the field of assistive technology during the ensuing discussion sessions. This paper provides an overview of the material presented by the participants, and explores the implications of their findings for one particular field of application—assistive technology for people with disabilities.  相似文献
