Crime prevention is an activity that, sooner or later, requires the concourse of science. But the dictates of science may not mesh well with the social, institutional and political considerations that are persistent and powerful determinants of collective action. To the extent that they are ignored, crime prevention is less scientific and more pragmatic. Using a marketing metaphor, this paper examines selected aspects of the supply of and demand for scientific crime prevention in Canada and Venezuela from 1949 to the present. In both countries, academic entrepreneurs are revealed to be a necessary factor in the sale of crime prevention to government. On the demand side, governments adopt and adapt crime prevention policies in relation to their broader perspective on social problems and social change. However, rising crime rates and climates of urgency reduce the attractiveness of crime prevention. Scientific crime prevention is easier to sell when crime rates are stable or declining.  相似文献

Legal and practical context. The streamlined procedure is asimplified patent litigation procedure that was introduced overtwo years ago in the English Patents Court and Patents CountyCourt. This article looks at the procedure, the way it has beenapplied since its introduction and the effect it has had onpatent litigation in the UK. Key points. The procedure was designed to deal with simple patentcases quickly and relatively cheaply. It is geared towards aone day trial taking place approximately eight months afterthe commencement of proceedings. Under the procedure there isno automatic disclosure, no experiments and cross-examinationis limited to permitted topics only. Although it was designedwith patents in mind, the procedure is available for all appropriateactions heard in the Patents Court and Patents County Court.It is only suitable, however, for relatively simple actionsin which complex findings of fact are not necessary. Conclusions. Not many actions have come to trial under thisprocedure, but its availability is nonetheless of great significanceto patent litigation in the UK. This is because it providesa new point of departure for directions in certain types ofaction and because its availability has increased access topatent litigation in the UK and has renewed interest in thePatents Court and Patents County Court as forums in which toissue patent proceedings.  相似文献

This article critically appraises the narrative of nationalist resurgence in China in the 1990s that structures much of the secondary literature on Chinese politics since Tiananmen. Adopting a post-structuralist method, Chinese texts from the 1990s are treated as discursive rather than as expressions of a common consensus, emergent ideology or political movement. This makes it possible to bring out the disparate points of view concerning the desirability of nationalism for China and to understand the strategies that are being deployed by authors within the context of everyday Chinese politics. It also reveals the significance of the absence from both the primary and the secondary texts of any mention of the advocacy of nationalism by the political leadership. When this hidden discourse is taken into account, it becomes evident that many of the texts that have been taken as expressions of a nationalist revival are either not particularly interested in nationalism or are highly sceptical concerning its possibilities for solving the problems faced by the Chinese state. Particularly significant is the way in which many of the texts locate themselves in relation to the official discourse on nationalism by appropriating its themes in order to promote and legitimate a wide range of other discourses with which it can be bound up, ranging from democracy to authoritarianism.  相似文献

Telecommunications regulation has experienced a fundamentalshift from rate regulation to increased reliance on compelledaccess, perhaps best exemplified by the Telecommunications Actof 1996's imposition of no fewer than four new access requirements.Unfortunately, each access requirement is governed by a separateset of rules for determining both the scope and the price ofaccess. The resulting ad hoc regime has created difficult definitionalproblems and opportunities for regulatory arbitrage. In thisarticle we propose a system inspired by the discipline of mathematicsknown as graph theory that integrates all of the different formsof access into a single analytical framework. This system separatesdifferent access regimes into five categories: (1) retail access,(2) wholesale access, (3) interconnection access, (4) platformaccess, and (5) unbundled access. It also provides insightsinto how each type of access complicates the already difficultproblems of network configuration and management and introducesinefficient biases into decisions about network capacity anddesign. The approach we propose also provides insights intothe transaction cost implications of the different types ofaccess. Drawing on the Coasean theory of the firm, our approachexamines the tradeoffs between internal governance costs andthe external transaction costs of providing access to offera theory of network boundaries. This framework shows how accessregulation distorts networks' natural boundaries and providesa basis for evaluating whether private ordering through marketswould lead to more efficient network design.  相似文献
