Abstract: This paper is concerned with an analysis of legislation, public administration and government expenditure decisions on policing activities. These three dimensions of government can be used as mechanisms of social control. Whether they are or not is an empirical question that has to be determined in each case. It is shown that there are no strict relationships between the three dimensions of government activity: separate decision-making is undertaken for each of the three dimensions. It is indicated that there are eight possible combinations of the three dimensions, assuming that the three dimensions of government activity are bivariate and discrete. The empirical analysis relates to the state of Queensland and it is concluded that Queensland can be described as a case consisting of authoritarian legislation, public administration contrary to the rule of law, and low policing expenditures.  相似文献

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

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

This article explores the reasons for the introduction of anticorruption agencies of a specific type in Eastern Europe. It is argued that one of the important functions of these agencies—which are stronger on information gathering, coordination and strategy rather than on investigation of concrete cases—is to give to the government some leverage over the anticorruption discourse. Presenting the anticorruption commissions and agencies as (discourse-controlling) instruments gives an answer to the troubling question why governing parties are at all interested in the introduction of such bodies. Apart from instrumentalization in political discourse, anticorruption bodies in Eastern Europe have had other effects as well. As shown in the Baltic case, institutional engineering provides for a brief window of opportunity during which political forces committed to integrity could gain the upper hand. The problem in Eastern Europe, however, is not the lack of such windows of opportunities—it is more the lack of really committed political forces capable of continuous and consistent anticorruption effort.  相似文献

This paper discusses empirical findings and theories about prison higher education and recidivism. The research designs of available evaluations of prison higher education are discussed. Their results in regard to arrest and return to prison after release are presented in tables and figures. Both opportunity theory and moral development theory have been used to justify such prison programs as crime prevention measures. A critical examination of the actual findings of the evaluations carried out up to now suggests that prison higher education may have had only a slight impact on recidivism. One could, therefore, doubt the value of opportunity theory and moral development theory to justify prison higher education as a crime control measure. However, the methods used in the evaluations of this program have been generally weak. Thus, there is a continuing need to carry out well-designed research on this question. The findings of follow-up studies of prison higher education have significance for issues of correctional education policy as well as criminological theory.  相似文献

In recent years, legislators in all fifty states have given grandparents rights to petition for visitation privileges with grandchildren that can be enforced over parental objections. Grandparent visitation rights reflect an effort to protect meaningful relationships children enjoy with nonparental caregivers, enlist the assistance of extended family when the child's nuclear family is disrupted, and defend the interests of grandparents themselves. This psycholegal analysis explores the direct and indirect consequences of grandparent visitation statutes for family functioning. Statutory provisions are summarized, and the effects of these statutes are evaluated in light of what is known about the role of grandparents in child development, how courts evaluate children's "best interests" in grandparent visitation disputes, and how these statutes can alter family functioning in informal ways. The authors conclude that there are risks as well as benefits to children and families in grandparent visitation statutes, and suggest directions for procedural and statutory reform.  相似文献

The main aim of this paper is to advance knowledge and (especially) theories about developmental and life‐course criminology (DLC). First, I review the widely accepted DLC findings that all DLC theories have been designed to explain. Second, I review more contentious and unresolved empirical DLC issues that might present challenges to DLC theories. Third, I describe my own DLC theory and specify how it addresses key empirical and theoretical questions. Fourth, I summarize five important DLC theories, by Catalano and Hawkins, Sampson and Laub, Moffitt, LeBlanc, and Thornberry and Krohn. Fifth, I identify differences in assumptions and predictions between my theory and the other five theories. Finally, I recommend a detailed comparison of the key features of all DLC theories, of their answers to key empirical and theoretical questions, and of their predictions regarding key unresolved empirical DLC issues.  相似文献

Esophageal and tracheal fistulas, which occur in 0.05% of medicolegal autopsies, were demonstrated in three cases by a postmortem radiographic technique using silicone rubber/lead oxide as a contrasting medium that vulcanizes at room temperature. In one 83-year-old male, a tracheoesophageal fistula was detected, which had developed after surgical repair of an esophageal rupture caused by a flexible fiberoptic endoscope. In a second case, carcinoma of the esophagus in a 78-year-old male had eroded the trachea and arcus of the aorta creating a fatal tracheoesophagoaortic fistula. In a third case, 55-year-old female developed a tracheobrachicephalic artery fistula as a result of an infiltrating cystic adenocarcinoma of the trachea, resulting in a fatal hemorrhage into the trachea. The results of this study indicate that diagnostic radiologic methods using a vulcanized contrasting medium are useful in supplementing normal dissection in autopsy cases with suspected fistulas of the esophagus or trachea.  相似文献
