环境服务谈判纳入GATS之中以及由此带来的法律适用上的冲突,从一个侧面折射出多边贸易体制下贸易与环境问题的复杂性.平衡与协调贸易与环境问题的难度与多边谈判的曲折,使许多问题已超出WTO体制的承载,通过对环境服务贸易在GATS协定中的法律适用的分析,反映出在WTO体制下处理好贸易与环境议题,尚需在理论与实践上作出进一步的探讨与努力.  相似文献

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method.  相似文献

This article characterizes the ways in which the actors in charge of designing and implementing public policies intervene to promote the emergence of alternatives to problematic technologies. It is based on a case study conducted in Argentina that focuses on initiatives to promote the development of biological agricultural inputs in the context of increasingly controversial chemical inputs. The study spotlights the political, institutional, and semantic efforts made by policy makers and public administrations to ensure these new inputs find their way into organizations and onto their agendas. Their work consists in attenuating the boundaries between chemical and biological inputs, and reducing opposition by creating categories and organizations that downplay potential dissension and highlight the possible coexistence of technological paradigms. Contrary to what the injunctions of technological substitution suggest, we show that putting alternative technologies on the public agenda depends largely on their inclusion in institutional and regulatory infrastructures originally designed for technologies that are likely to decline. More broadly, it relies on the construction of continuity between the two types of technologies.  相似文献

Members of parliament are key actors for the implementation of energy transitions, such as phasing out nuclear power. Before legislators can cast their maybe decisive vote in parliament, they need to run for office and actively strive for election. This paper assesses what political candidates oppose renewable energy transitions and questions whether the energy issue matters in national elections, and thus has consequences for the implementation of new sustainable energy sources. We analyze these questions by first describing the specific characteristics of political candidates. The paper then evaluates the relevance of the energy issue for electoral success in three national elections in Switzerland (2007, 2012, and 2015). Based on candidate data from the voting advice application smartvote.ch, we find that female candidates support ETs more than men do; that especially the French‐speaking part of the country is more in favor of a nuclear phase‐out, and that younger candidates are also more open toward restructuring the energy system than older candidates are. Our models further show that the energy issue does not matter in elections, independently from its salience in the respective election campaigns. Candidates are thus relatively free to choose their position on the issue and do not have to fear consequences at the ballot. However, candidates of center parties, in contrast to the pole parties, are sensitive to the energy issue and reflect public mood in their positions.  相似文献

通过对乐山市三所高校的教师成长环境进行调查研究,结果发现:在自身环境上,教师充分肯定自己的教学能力并有迫切的学习需求;教师的人际关系基本和谐;部分教师学习时间相对匮乏。在外部环境上,组织制度建设有待干完善。主要表现为:奖惩制度科学程度不够,不能充分发挥其重要作用;教学评价的科学性不强,需要加以完善;教师课程教学存在不稳定现象;后勤保障体系服务有待于提高;教师培训体系依然不够完善。因而,促进教师成长,教师环境建设需要加以改善,尤其是外部环境。  相似文献

科学发展观“以人为本、全面协调可持续发展”的要求与环境行政决策的合法化、科学化、民主化的诉求并行不悖、相互促进。环境行政决策应响应科学发展观的要求,进行体系上的重构,顺应环境法治的时代要求。具体因应对策为:环境行政决策应以“以人为本”为核心,进行必要的法律规制(实体规制与程序规制)和行政三分体制(决策、执行、监督)的创新,形成决策的合法、科学、民主与决策效率和谐互动的理想状态。  相似文献

The flow of attention in the policy process is dynamic and disruptive. While we know changes in issue attention often result in policy change, the causal mechanisms underlying the different stages of the attention allocation process remain unclear. This article uses Punctuated Equilibrium Theory to examine an underdeveloped aspect of issue attention within policy‐making institutions: how specific policy indicators influence the entry and exit of issues on policy‐making agendas. Partisan issue attention in the House of Representatives is used to analyze a significant change to U.S. offshore oil and natural gas drilling policy in 2008. The results highlight how historically high gasoline prices precipitated a shift in attention to offshore drilling and subsequent policy change. Moreover, gasoline prices Granger‐cause attention to energy policy in partisan speeches over time. The analysis further reveals how competing policy frames and a salient focusing event shaped congressional and public discourse, leading to subsequent changes in attention. Taken together, the findings broaden our understanding of the policy process by identifying the specific forces behind the entry and exit of issues on the policy‐making agenda.  相似文献

This article examines the role that overlapping committee jurisdictions play in fostering or hindering attention to environmental and energy issues in the U.S. Congress. The Select Energy Independence and Global Warming Committee, created by House Democrats in 2007 , and its chairman Rep. Ed Markey took advantage of opportunities within the existing jurisdictional arrangement to increase attention to these issues despite lacking any legislative authority. Data from the 110th and 111th Congresses show that the Select Committee held more hearings on climate change and alternative energy, and on environmental and energy policy generally, than any other committee. The committee also increased the range of sources informing debate on these issues by calling different witnesses than other committees. These findings have important implications for the relationship between institutional structure and agendas and for Congress' policy‐making role on energy and the environment.  相似文献
