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

This article addresses some of the implications of the EU's proposed Marine Strategy Directive for ongoing work in the regional seas conventions and for national work on regional marine strategies. The starting point is the proposed directive's focus on the ecosystem approach to the protection of the marine environment. Key elements within this approach are analysed, such as integration of environmental considerations into other policy areas; introduction of ecological quality objectives; and establishment of holistic monitoring and assessment programmes. Is it possible to transform these concepts into legally binding obligations? What will the implications of the proposed directive be for the rights and obligations of EU Member States under international law? A Management Plan for the Norwegian Part of the Barents Sea ('Barents Plan') was adopted by the Norwegian Government in March 2006 and approved by the Norwegian Storting (Parliament) in June 2006. It provides an example of a concrete application of the concepts in the proposed directive. Based on an analysis of the proposed Marine Strategy Directive and the Barents Plan, some key political and legal challenges are discussed in this article.  相似文献

Based on interviews with facility managers in the electroplating and chemical industries, this study examines regulated firms’ perceptions of how various instrumental, normative, and social factors motivated their firms’ environmental actions. We found that “implicit general deterrence” (the overall effect of sustained inspection and enforcement activity) was far more important than either specific or general deterrence, and that deterrence in any form was of far greater concern to small and medium‐sized enterprises than it was to large ones. Most reputation‐sensitive firms in the environmentally sensitive chemical industry chose to go substantially beyond compliance for reasons that related to risk management and to the perceived need to protect their social license to operate. Almost half our respondents also provided normative explanations for why they complied. Overall, we conclude that there are various, often interwoven, strands that must be taken into account in understanding what motivates corporate environmental behavior, and how they play out depends very much on the size and sophistication of companies themselves and on the characteristics of the industry sector within which they are located.  相似文献

Local government reforms in contemporary Russia are placed in the broader contexts of political reform under Putin and the historical relationship between local administration and the state. Reforms of local government thus help illuminate the architecture of contemporary state building in Russia and the degree to which contemporary Russia perpetuates political traditions. This study reviews the antecedent action in local government prior to the Putin era. It then examines the Kozak Commission and the new law on local government, assessing the strengths and weaknesses of these reforms. Finally, this study examines the challenges of implementing the reforms and what these challenges tell us about devolution and centralisation under Putin.  相似文献

A fatality following ingestion of the drug baclofen (Lioresal) is described. Baclofen was identified in urine by gas chromatography/mass spectrometry. After derivatization with trinitrobenzene sulfonic acid, baclofen was quantitated in serum and urine by high-performance liquid chromatography. The concentration of baclofen was 17 mg/L in serum and 760 mg/L in urine collected approximately 12 h after the overdose. To our knowledge, this is only the second reported fatality involving a baclofen overdose. The previous case did not include quantitation of baclofen in any biological fluid.  相似文献

The dominant theories of delinquency tend to view the delinquent as a deprived individual who engages in delinquency because of forces beyond his or her control. This paper challenges that image, awing that many adolescents possess resources that increase their power and autonomy. This power and autonomy may be used to reduce social control and increase “Illegitimate means,” which in turn increase the likelihood of delinquency. Whether adolescents use their resources for delinquent ends is conditioned by several factors, most notably the adolescent's predisposition for delinquency, the benefits and costs of employing resources for delinquent ends in a particular situation, and the adolescent's perceived self-efficacy. Data from two nationally representative surveys of adolescents are used to analyze the relation between resources and delinquency among adolescents differing in their predisposition for delinquency. In most cases, resources are positively related to delinquency when the predisposition for delinquency is high.  相似文献

The extent to which local life circumstances influence criminal activity has been the focus of much theoretical debate. Although empirical research has been initiated, it remains limited. Herein, we use data on 524 serious offenders from the California Youth Authority for a seven‐year post‐parole period to examine the relationship between changes in local life circumstances and criminal activity. We extend previous research by employing a statistical model that accounts for the joint distribution of violent and nonviolent crime during the late teens and twenties in order to present information on patterns of criminal activity during a newly recognized developmental period of the life course, “emerging adulthood.”  相似文献
