Herbal smoking blends, available on the German market were analyzed and several known synthetic cannabinoids were identified (JWH-122 and JWH-018). In addition, we isolated a new active ingredient by silica gel column chromatography and elucidated the structure by nuclear magnetic resonance (NMR) methods. The compound was identified as JWH-307, a synthetic cannabinoid of the phenyl-pyrrole subclass with known in vitro binding affinities for cannabinoid receptors. To date, this is the first appearance of this subclass of cannabimimetics in such products. JWH-307 has been further characterized by gas chromatography accurate mass spectrometry (GC-HRMS), electrospray tandem mass spectrometry (ESI-MS/MS), ultraviolet (UV) and infrared (IR) spectroscopy. JWH-018 was among the first compounds banned by many countries world-wide including Germany. The identification of JWH-018 was striking, since this is the first report where JWH-018 recurred on the German market thus violating existing laws. A generic method was established to quantify synthetic cannabinoids in herbal smoking blends. Quantification was achieved using an isotopically labeled standard (JWH-018-D(3)). JWH-018 was found at a level of 150mg/g while JWH-122 and JWH-307 occurred as a mixture at a total level of 232mg/g.  相似文献

Democracies are, by definition, marked by a strong normative commitment to innovation and change, and all democratic regimes must seek to generate innovations both to keep their fundamental promise and to secure their own survival. In response to the latent crisis of representative democracy, recent political research has devoted eager attention to innovating democratic institutions, yet with conspicuously little regard for the likely effects of such reform proposals on the innovation-related performance and innovation capacity of democratic regimes. Indeed, some reform proposals, if implemented, would appear to reduce rather than increase the innovation capacity of representative democracies. Innovation-focused leadership may be able to fill that gap and provide what even the best institutions alone are unable to accomplish. In contrast to recent research on leadership and innovation in the public sector, which tends to centre on forms of collaborative leadership within networks, this article emphasizes the importance of individual leaders, and more specifically of political chief executives whose status and position in the governance process have been significantly enhanced by a combination of different factors. However, while leadership might be the key to democratic political innovation, innovative leadership and institutional engineering remain closely related to one another.  相似文献

This article analyses the electoral support and parliamentary representation of right‐wing populist parties in Austria (FPO) and Switzerland (SD, AP/FPS, Lega dei Ticinesi). Contrary to the empirical evidence in many other fields of the political systems in these two Alpine republics, the analysis reveals strong differences rather than similiarities in the electoral support of right‐wing populist parties in both countries. This is explained by the differences in political culture and historic circumstances, performance of the established (governing) parties, party political penetration of social institutions, structure of the party system and the contrasting importance of direct‐democratic structures in the two countries. The exceptional skill of the right‐wing populist leader in Austria can also be seen as a significant factor. In contrast, neither social and economic variables, such as the economic situation, the unemployment rate and the overall number of asylum‐seekers, nor the strength and performance of green‐alternative parties seem to be important factors in explaining the differing success of right‐wing populist parties in Austria and Switzerland.  相似文献

This paper argues that the anticipation of protection can have astimulating effect on exports instead of the commonly claimed effect of harassment. If protection serves market cartelization by fixing export quantities or prices, exporters may have an incentive to increase their sales abroad in order to secure a large share of the expected rent, which is brought about by the anticipated import restriction. This may even result in sales below marginal costs or dumping.The effect of the protectionist threat may then be the reverse of what is intended: it can raise the speed of import penetration and it can provoke dumping. A formal model and a supportive institutional analysis of EC trade protection is supplemented by preliminary empirical evidence.  相似文献

The goal of this paper is to evaluate the attribution of policy prerogatives to European Union level institutions and compare them to the implications of normative policy models and to the preferences of European citizens. For this purpose we construct a set of indicators to measure the policy-making intensity of the European Union (European Council, Parliament, Commission, Court of Justice, etc.). We confirm that the extent and the intensity of policy-making by the EU have increased sharply over the last 30 years, but at different speeds, and in different degrees, across policy domains. In recent years the areas that have expanded most are quite remote from the EEC’s original mission of establishing a free market zone with common external trade policy. On the contrary some policy domains that would normally be attributed to the highest level of government remain at national level. We argue that the resulting allocation of prerogatives between the EU and member countries is partly inconsistent with normative criteria concerning the assignment of policies at different government levels, as laid out in the theoretical literature.  相似文献

‘Political leadership’ is one of the classic subjects of political science research on an international scale. Recently, in modern western democracies, ‘leadership’ has gained additional importance as a political function to evaluate governments and political leaders and is seen as rather independent of the policy dimension of leadership. Despite this increased relevance of ‘political leadership’, it has remained among the most neglected major issues in political science, particularly within research in the German-speaking world. This article discusses a wide range of recent approaches to studying ‘political leadership’. It then argues in favour of an ‘interactionist’ approach which takes into account both of the crucial empirical variables which influence the leadership process, the institutional, societal, and personal factors as well as political circumstances, and the normative expectations towards political leadership in modern established democracies.  相似文献
