The analytical properties for a new street drug, 4-methylthioamphetamine (4-MTA), are presented. This new compound was found in tablets sold on the illicit market in the Netherlands and Switzerland in 1997 and 1998. The intermediate 1-(4-methylthiophenyl)–2-nitropropene was also found in a clandestine laboratory in the Netherlands in January 1997.In this study, reference standards were prepared and characterized. The ultraviolet, infrared and nuclear magnetic resonance spectral properties as well as the chromatographic and mass spectrometric (MS) data are reported.  相似文献

Americans' confidence in government is low by historical standards. We fielded a national telephone survey to examine influences on government confidence and whether public discontent was affected by altering the salience of specific government operations. We used a question order experiment where we alternated between first asking a general question about confidence in government and first asking about confidence in specific government operations. We found that posing the specific policy questions first elevated general confidence more than the reverse. The largest and most noticeable effects were observed for Republicans and those most knowledgeable and attentive to politics. Findings of context effects and the partisan subgroup differences are consistent with existing theories on public opinion change as well as with previous question order experiments. But, evidence that the cognitive elite was especially influenced by question order challenges previous theories that presumed that its sophistication made it immune to influence. We suggest that education and political knowledge expand rather than contract the opportunities for priming.  相似文献

Engaging in comparative lobbying research is a challenging task, because public affairs is complex and highly context-dependent. Thus, qualitative case studies have been researchers' primary choice. However, the case method has been subject to much debate surrounding its rigor, in terms of reliability, internal validity, and generalizability, and particularly its potential for theory building. To propose a framework for researchers conducting lobbying case studies as well as for reviewers receiving such work, we apply a positivistic approach on case study rigor from management studies and expand the framework to tackle the specific challenges of comparative qualitative lobbying research. Thus, we expand the research framework by a set of variables specific to public affairs: We add enrichment for internal validity, contextuality, and comparability for external validity, interdisciplinarity for construct validity, and hypertext-searchable databases for reliability. Thereby, we aim to transfer the lessons learned from management studies in terms of rigorous qualitative case studies to public affairs to help build novel and explanatory theory in the field and to provide guidance to researchers how to design a rigorous case study.  相似文献

This paper focuses on the framing strategies lobbyists apply to influence public policy in a case on nuclear emission data in Switzerland. Framing analysis is at the heart of communication science and has been applied in lobbying settings, but framing theory has not yet been fine‐tuned to the specificities of public affairs research. This qualitative case study gives insights into the dominant frames seven actors ranging from corporations to nongovernmental organizations to public institutions employ to defend a legal court case in the nuclear power industry. The results of the document analysis and the interviews show that frames travel among diverse actors and only some are picked up by the courts, at times stating a position opposite to the one initially intended by the frame sponsor. A public affairs‐specific integrated process model of framing is presented that views the media in the role of a moderator in the framing process and pronounces the lobbying organizations' strategic goals, the different stakeholders as target audiences, and the outcomes of the public affairs process.  相似文献

Historical analyses and contemporary social psychological research demonstrate that prevailing systems, institutions, and practices espouse an ideology of conflict between humans and the natural world. The established paradigm of society espouses domination of and separation from the natural environment, and manifests in environmentally detrimental attitudes and practices. Ecological exploitation appears to stem from the same root socioeconomic processes as social injustice—the hierarchical arrangement of power which places some groups and the environment in a position devoid of power or rights. Accordingly, endorsement of social and environmental injustice is exacerbated by tendencies toward domination and hierarchy, such as social dominance orientation and right-wing authoritarianism. Moreover, injustice is perpetuated by motivation to uphold and justify social structures and the dominant paradigm, which stifles societal change toward intergroup fairness and equality and motivates denial and neglect in the face of environmental problems. Ideological tendencies in service of the system, including political conservatism, belief in a just world, and free market ideology, contribute toward perpetuating injustice as well as anti-environmental sentiment and behavior. Considering the shared psychological and ideological underpinnings of social and environmental injustice point to important interventions, such as cultivating interdependence through contact, fostering inclusive representations, and harnessing ideological motives toward overcoming resistance to change, and carry implications for expanding the scope of justice theory, research, and practice.  相似文献

Using the example of intermediaries in business–state relations, this essay addresses the evolution of corruption in Russia which has been facilitated by the introduction of a neoliberal system of market relations. Based on empirical studies of small and medium-sized enterprises in Russia, the essay demonstrates how intermediaries (which are also present in Western market economies and serve the function of reducing firms' transaction costs) have adapted to the local system in order to serve as providers of both legal and illegal (corrupt) services. Disputing the pervasive claim that neoliberalism and corruption are mutually exclusive phenomena, we argue that in ‘incoherent’ democracies like Russia, where properly functioning democratic institutions and a developed civil society are lacking, neoliberalism has led to the expansion of corruption.  相似文献

The Russian policy on critical infrastructure protection was outlined in the early 2000s and has been consolidated in recent years as a part of the national security strategy. This policy is evolving against a background composed of an uneasy combination of factors: the degeneration of infrastructures critical for the country's economic and social development, and the de-legitimization of political institutions responsible for protecting ‘population’ and ‘territory’. The recent major catastrophes in Russia, the notorious forest fires in 2010 in particular, have become examples of political events that offer a point of reference for the current regime's failure to uphold its promises of ‘order and stability’.  相似文献

Currently, the use of isotopic ratio as corroborative evidence in criminal trials is explored. Beyond the analytical challenges that have been reported elsewhere, the crucial issue of the interpretation of analytical results in a fair and balanced way remains poorly documented. The aim of this paper is to propose a likelihood ratio approach for the evaluation of stable isotope data acquired from semtex samples. It will also lead to recommendations in relation to the acquisition of normalised international data.  相似文献

The suitability of liquid-liquid extraction (LLE) and solid-phase extraction (SPE) for the preparation of impurity extracts intended for gas chromatographic profiling analyses of amphetamine were evaluated. Both techniques were optimised with respect to the extraction of selected target compounds by use of full factorial designs in which the variables affecting the performance were evaluated. Test samples consisted of amphetamine synthesised by the Leuckart reaction, by reductive amination of benzyl methyl ketone and by the nitrostyrene route. The performance of LLE and SPE were comparable in terms of repeatability and recovery of the target compounds. LLE was considered the better choice for the present harmonised amphetamine profiling method due to the lack of information on the long-term stability of SPE columns.  相似文献
