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

Although there has been speculation regarding the pervasiveness and nature of judicial decisions regarding life-sustaining medical treatment (LSMT), no attempt has been made to empirically assess their prevalence or the issues they address. An exploratory study utilizing a mail survey of a nationwide random sample (N = 905) of state trial court judges was conducted to provide initial information regarding this decision-making process. Twenty-two percent of the responding judges had heard at least one LSMT case, and judicial review did not appear endemic to particular states. The number of judges hearing LSMT cases dropped from 1975 to 1981 but has increased since then. Three major issues predominate: patient competency, appointment of a surrogate decisionmaker, and resolution of the ultimate issue of forgoing LSMT. Relatively few cases either contested a prior directive's validity or involved imposing sanctions for instituting or forgoing LSMT. Although subject to different interpretations, the results suggest the courts are having a significant impact on certain aspects of the LSMT decision-making process. However, the infrequency with which any one judge is called upon to make an LSMT decision causes concern about the judiciary's ability to respond in a timely and appropriate manner. With their potential for a profound effect on the actions of health care providers, greater attention to this decision-making process is warranted.  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
