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

COMPSTAT, the latest innovation in American policing, has been widely heralded as a management and technological system whose elements work together to transform police organizations radically. Skeptical observers suggest that COMPSTAT merely reinforces existing structures and practices. However, in trying to assess how much COMPSTAT has altered police organizations, research has failed to provide a broader theoretical basis for explaining how COMPSTAT operates and for understanding the implications of this reform. This article compares two different perspectives on organizations—technical/rational and institutional—to COMPSTAT's adoption and operation in three municipal police departments. Based on fieldwork, our analysis suggests that relative to technical considerations for changing each organization to improve its effectiveness, all three sites adopted COMPSTAT in response to strong institutional pressures to appear progressive and successful. Furthermore, institutional theory better explained the nature of the changes we observed under COMPSTAT than the technical/rational model. The greatest collective emphasis was on those COMPSTAT elements that were most likely to confer legitimacy, and on implementing them in ways that would minimize disruption to existing organizational routines. COMPSTAT was less successful when trying to provide a basis for rigorously assessing organizational performance, and when trying to change those structures and routines widely accepted as being "appropriate." We posit that it will take profound changes in the technical and institutional environments of American police agencies for police departments to restructure in the ways anticipated by a technically efficient COMPSTAT.  相似文献

What is required for sustaining an alliance between union and environmental activists? Applying grounded theory to a case study in the Costa Rican banana sector, this article reveals five historical phases. First, unions and environmentalists identify common opportunity structures for joint action. Second, a preexisting network becomes a resource for mobilization. Third, the new coalition engages in communicative action that leads to shared identity and cultural framing and a foundation for handling exogenous global forces. Market policy changes in the fourth phase stimulate a transnational activist network and framing linkages. Dramatic supply disruptions in the fifth precipitate autonomous organizational approaches that require reframing, identity extension, and flexibility. This study argues that the Costa Rican case can be generalized to other labor‐environmental coalitions if such alliances create simple, open structures that agilely adapt to external opportunity structures and expand frames that encourage collaborative autonomy and dualistic collective definitions.  相似文献

He was only a little monkey, a very little one the first timeI saw him, not more than 9 inches tall; and when he died 3 yearslater, fully grown, he did not measure more than a foot anda half.  相似文献
