At the time of the election of the European Parliament (EP) in 2014, the European Union (EU) was heavily affected by a multifaceted crisis that had – and still has – far-reaching implications for the political system of its member countries, but also for the European level of governance. Against the background of the strong Eurosceptic vote in the 2014 EP elections, this study aims to investigate in which way Eurosceptic parties of the left and the right respond to the multiple crises of the EU. Using data from the Euromanifesto Project from 2004/2009 and 2014, changes in the party positions towards the EU are analysed in the shadow of the multiple crises and the reasons thereof are explored. The findings show a general anti-European shift among the two types of Eurosceptic parties. Nevertheless, the changes in the EU polity tone are not determined by issue-based repercussions of the multiple crises, but by the EU-related evaluation – the polity mood – of the national citizenry. For far-right Eurosceptic parties, the shift is moderated by the level of public support for EU integration in their national environment. Among far-left Eurosceptic parties, by contrast, it is moderated by the more specific public attitudes about the monetary union policy of the EU. Consequently, political parties when drafting their manifestos for EP elections are not so much guided by the objective severity of political problems or by the evaluations of these problems by the citizenry. What matters in the end is the link that citizens themselves are able to establish between the severity of political problems, on the one hand, and the responsibility of the EU for these problems on the other. This has important consequences for understanding of the nature and substance of political responsiveness within the EU system of multilevel governance.  相似文献

Cyanide is a powerful and rapidly acting poison. In Japan, cyanide poisoning is rare, and regular cyanide testing can be costly and time consuming. In contrast, alcohol analysis is routinely performed in most forensic laboratories. In this study, we attempted to develop a method for the simultaneous quantification of cyanide and alcohols in blood using headspace gas chromatography (HS–GC). As nitrogen-phosphorus detection (NPD) is more sensitive to hydrogen cyanide than mass spectrometry (MS), a Deans switch was used to switch the detectors during a single run. The separation provided by three analytical columns, PoraBOND Q, CP-Sil 5 CB, and HP-INNOWax, was investigated, and PoraBOND Q was selected. The use of HS–GC–MS/NPD with a Deans switch enabled the simple and simultaneous quantification of cyanide, ethanol, and 1-propanol. Eighteen other volatile compounds were detected in the SIM/scan mode of the MS.  相似文献

行政体制改革是一项长期而艰巨的工程。目前的论述更多关注于机构改革,而从系统论的观点来看,只有同时兼顾体制内、外两个层面,才有可能理清改革的原因,从而为体制改革的顺利推行提供保障。  相似文献

The usage of herbal incenses containing synthetic cannabinoids has caused an increase in medical incidents and triggered legislations to ban these products throughout the world. Law enforcement agencies are experiencing sample backlogs due to the variety of the products and the addition of new and still‐legal compounds. In our study, proton nuclear magnetic resonance (NMR) spectroscopy was employed to promptly screen the synthetic cannabinoids after their rapid, direct detection on the herbs and in the powders by direct analysis in real time mass spectrometry (DART‐MS). A simple sample preparation protocol was employed on 50 mg of herbal sample matrices for quick NMR detection. Ten synthetic cannabinoids were discovered in fifteen herbal incenses. The combined DART‐MS and NMR methods can be used to quickly screen synthetic cannabinoids in powder and herbal samples, serving as a complementary approach to conventional GC‐MS or LC‐MS methods.  相似文献

论亚洲经济一体化   总被引:10,自引:0,他引:10  
在市场力量和各国政府的推动下,亚洲的区域合作与经济一体化正在蓬勃开展,不仅是东亚地区,南亚、中亚、西亚地区的经济一体化也出现良好的发展势头,同时还出现了跨次区域经济一体化趋势。本文论述了亚洲经济一体化的发展现状,着重分析了东盟、中国、日本、韩国和印度的区域经济一体化战略,并勾画了“泛亚洲经济共同体”蓝图。目前,亚洲经济一体化的显著特点是各种形式、各种范围的区域合作机制并存,这一局面仍将继续。  相似文献

印俄战略伙伴关系的新发展   总被引:2,自引:0,他引:2  
印俄战略伙伴关系是冷战时期印苏特殊关系的继承和演进。进入21世纪以后,随着俄罗斯的复兴和印度的崛起,双方重新审视对方在各自战略棋盘上的分量,决定建立"战略伙伴关系",加强在政治、经济、军事、科技、能源等领域的合作。由于俄罗斯与中国的"战略协作伙伴关系"不断深化,印度与中国"面向和平与繁荣的战略伙伴关系"正在推进,印俄战略伙伴关系对于中国具有某种积极意义。尽管印俄对中国的态度有一定区别,但是印俄战略伙伴关系对中国的良性作用值得肯定。  相似文献

The article considers the subject of clickstream data from aEuropean/US perspective, taking into account the Data ProtectionFramework (Data Protection Directive 95/46/EC; Directive onPrivacy and Electronic Communications 2002/58/EC) and the USlegal framework and in particular, the Wiretap Act U.S.C. 2701(2004) and related statutes. It examines the extent to whichclickstream data is considered "personal data" within the DataProtection Directive and the implications to consumers and businesses.  相似文献
