This paper links the policy context regarding S&T parks to the objectives and characteristics of the established parks and incubators in a relatively small, converging European country. S&T parks and incubators in Greece during the past decade and a half have gradually shifted in terms of ownership and management from university/research institute to the private sector and in terms of financing from public to private funds, also involving the provision of seed capital and access to venture capital. This gradual shift toward more private engagement has created a variety of models out of which, it is hoped, successful innovative companies will emerge in larger numbers than in the past.

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

Abstract. The paper replies to Bix and Soper ( Bix 2007 ; Soper 2007 ). Bix's paper raises methodological questions, especially whether a form‐theorist merely needs to reflect on form from the arm‐chair so to speak. A variety of methods is called for, including conceptual analysis, study of usage, “education in the obvious,” general reflection on the nature of specific functional legal units, empirical research on their operation and effects, and still more. Further methodological remarks are made in response to Soper's paper. Soper suggests the possibility of substituting “form v. substance” of a unit as the central contrast here rather than form v. complementary material or other components of a unit. Various reasons are given here for not doing this. Among other things, it is also argued here that form does not, contrary to Soper's suggestion, always follow substance.  相似文献

Whether a law can bring about change has been an important topic of debate in the literatures of law, sociology and education. With reference to the 2006 revision of compulsory schooling legislation in China, this article examines the functions and limits of the use of law to effect educational change. It explores why and how China continues to rely on instrumental use of the law to bring about change and rectify problems that the previous legislation did not. The article shows that law can be used as a tool for social justice that helps defend children's right to access basic quality education. However, the realization of legislative change requires favourable economic, social and/or cultural conditions, the support of extra-legal means and a concerted effort by all actors in interpreting and enforcing the law.  相似文献

This article evaluates the effectiveness of OAS mechanisms for safeguarding democracy through multilateral diplomacy, what some scholars have dubbed the interamerican defense of democracy regime. Drawing on a range of international relations theories, this study derives competing hypotheses about member states' responses to democratic crises in the Americas. It then analyzes all instances in which a collective response—that is, an application of Resolution 1080 or the Inter-American Democratic Charter—was debated in the OAS between 1991 and 2002. Patterns of state behavior suggest that domestic politics, rather than the structural or systemic traits of the interamerican system, best explain foreign policy responses to crises of democracy in the region. The OAS record in confronting such crises is uneven.  相似文献
