An impressively large number of clandestinely produced controlled-substance analogues (designer drugs) of amphetamine with high structural variety have been encountered in forensic samples in recent years. The continuous designer drug exploration and their widespread consumption results in an increasing number of reports regarding abuse and intoxication. This study presents the analytical properties of a series of new fluoro-methoxy-substituted controlled-substance analogues of amphetamine. Three ring positional isomeric fluoroamphetamines, two isomeric fluoromethoxyamphetamines, two N-alkyl 4-fluoroamphetamines, and one 4-fluorophenylbutan-2-amine were identified and differentiated by gas chromatography-mass spectrometry (GC-MS), 1H- and 13C-nuclear magnetic resonance (NMR), and gas chromatography-infrared spectroscopy (GC-IR). The regioisomeric 2-, 3-, and 4-fluoroamphetamines and the regioisomeric fluoro-methoxyamphetamines show virtually identical mass spectra so that this method is insufficient to discriminate between these closely related compounds. The mass spectra of the acetylated compounds allowed a differentiation of the 4-fluoroamphetamine from its regioisomeric 2- and 3-fluoroamphetamines. The gas chromatographic properties of the three regioisomeric fluoroamphetamines and their acetylated and trifluoroacetylated derivatives are also so similar that a complete separation of these compounds could not be achieved under GC-MS conditions. The two isomeric compounds 5-fluoro-2-methoxyamphetamine and 3-fluoro-4-methoxyamphetamine on the other hand showed significant different gas chromatographic retention times so that a separation was uncomplicated. The trifluoroacetylation of these compounds proved to be an effective method for their mass spectral differentiation. Gas chromatography-infrared spectroscopy and 1H- and 13C-nuclear magnetic resonance allowed an unequivocal differentiation of all studied regioisomeric fluoroamphetamines and fluoro-methoxyamphetamines. 相似文献

Globalization processes have rendered non-state actors an integral part of global governance. The body of literature that has examined non-state actor involvement in global governance has focused mainly on whether and how non-state actors can influence states. Less attention has been paid to the comparative advantages of non-state actors to answer questions about agency across categories of non-state actors, and more precisely what governance activities non-state actors are perceived to fulfil. Using unique survey material from two climate change conferences, we propose that different categories of non-state actors have distinct governance profiles. We further suggest that the different governance profiles are derived from particular power sources and that agency is a function of these profiles. The study thereby contributes to a strand in the literature focusing on the authority of non-state actors in climate governance and broadens the methodological toolkit for studying the “governors” of global governance. 相似文献

Social Inequality and the Perceived Income Justice Gap 总被引:2,自引:0,他引:2
This paper attempts to answer the question whether justice evaluations of income inequality in a society are determined more by country differences or by the social position an observer occupies. In very general terms what we study is whether, in shaping justice beliefs, cultural factors are more important than social-structural ones, or vice versa. In view of transformation societies, country differences are conflated with differences in the transformation processes the countries are experiencing. This is why we distinguish different types of transmations with regard to the postcommunist countries of Eastern and Central Europe testing empirically whether these transformation types exert influence on the justice beliefs, and how this influence compares to that of positional effects. With International Social Justice Project (ISJP) data of 1991 and 1996, we study the Czech Republic, Hungary, Russia, Bulgaria, East Germany, and—as a western referent society—West Germany. Main results are that in the early phase of transformation the different transformation types as well as social positions matter in shaping justice evaluations, over time, however, the types of transformation clearly lose influence. In 1996, compared to 5 years earlier, the countries have become similar in that most of the variation in the perception of the income justice must now be attributed to the positional differences of individuals. We conclude that the characteristics of the transformation processes decrease in importance for determining public views about social justice. In this respect, the transformation societies of Eastern and Central Europe may well be on the route to becoming more like western societies. 相似文献

The schools of thought that Richard Musgrave and James Buchanan represent in the field of public finance differ a great deal. Musgrave represents the insider-Harvard vision of socio-political reality while Buchanan represents the outsider-Chicago-Virginia-public choice vision. The foundation of different schools of thought by Musgrave and Buchanan is surprising insofar as both Musgraveand Buchanan call Knut Wicksell their intellectual father and claim their own work to stand in the Wicksellian tradition. In this paper, the influence of Wicksell on the works of Musgrave and Buchanan is traced out. The paper comes to the conclusion that it is Buchanan on whose work Wicksell had the strongerinfluence. 相似文献
