A 42-year-old female drug user who was enrolled in a methadone maintenance program was found dead in her apartment. Cause of death was an intoxication with chloral hydrate and L-methadone. Trichloroethanol (TCE), the primary metabolite of chloral hydrate, was quantified by solid phase microextraction (SPME) and GC/MS in heartblood (27 micrograms/ml) and urine (338 micrograms/ml). D- and L-methadone were differentiated by chiral HPLC, which showed that only L-methadone had been taken. The quantitation of L-methadone and its metabolite EDDP was carried out by GC/MS from heartblood (1300 ng/ml and 86 ng/ml, respectively), urine (5239 ng/ml and 4960 ng/ml, respectively) and gastric contents (159 ng/ml and 122 ng/ml, respectively). The concentrations of both--trichloroethanol and methadone--were in toxic ranges.  相似文献

The paper deals with a segment of the digitization of work: It examines the forms and conditions of work in the so-called sharing economy (SE). Based on the analysis of 67 internet platforms, three segments – the “exchange and gift economy”, the “niche and side job economy” as well as the “platform economy” – are distinguished as separate institutional spheres of the SE. On this basis, five dimensions of work in these segments are comparatively analyzed. It is shown that patterns of work differ among the three segments with view to activity patterns, gratification, qualification requirements, the role of technology and control mechanisms. The paper then discusses a shift in the determinants of work: it is argued that classical factors no longer prevail, but are partly supplemented, partly replaced by “internet communities” and the socio-technical structures and strategies of the platform providers. Not least, the absence of formal employment contracts in platform-user-relationships stands out.  相似文献

For 50 years after World War II, Latvia was incorporated into the former Soviet Union. Although in theory the use of regional languages was not discouraged, in practice knowledge of Russian was obligatory. Since restoration of the country’s independence in 1991, Latvian has again become the official language, and knowledge of Russian is widespread but optional. These political events have created a natural experiment in the possible effects of almost universal bilingualism on a language. In this study, we examine the phonetic characteristics of the Latvian syllable intonations across generations. Native speakers of Latvian, ranging from retirement age to teens, were recorded reading a word list, sentences, and a short narrative. We find that younger speakers who used Latvian only about half of the time showed fading in their pronunciation of the intonations.  相似文献

This article reports the results of a randomized field experiment conducted three weeks before the 2017 federal election in Germany. Four different versions of a letter to the editor were sent to all the German daily newspapers that handle letters to the editor independently. The versions differed in the subject matter of the letter, the chancellor Angela Merkel versus the main challenger Martin Schulz, and in the evaluation of this subject, positive versus negative. The experiment was designed to test for three different types of media bias: political bias, negativity bias, and incumbency dominance. We find no political bias in the decisions to print letters, and no statistically significant negativity bias. We do observe incumbency dominance: letters about the chancellor were 40% more likely to be printed.  相似文献

The recent scholarship on social movement outcomes has called for explanations about how movements influence economic outcomes. This article demonstrates in practice how a dynamic and relational approach, coupled with a Bourdieuian analysis of social, symbolic, and territorial space, can be utilized in explaining the influence of movements in contentious politics around investment projects. Based on participant observation and comparison across the Brazilian Landless Movement (MST) groups in areas of paper industry expansion, I assess the different movement strategies and their influence on pulp project outcomes. I reinterpret the ideal ‘MST model’ as constructed by specific strategies promoting contentious agency: organizing and politicizing, campaigning by heterodox framing, protesting, networking, and embedded autonomy vis-à-vis the state. A Qualitative Comparative Analysis comparing the expansion of 13 pulp holdings between 2004–2008 shows how these strategies influence investment pace. When both contentious and conventional strategies were used, movements managed to slow pulpwood plantation expansion.  相似文献

Conventional wisdom in new institutional economics suggests that property rights become more secure following sovereign commitment. The article tests this axiom in the crucial case of the 2004 Orange Revolution in Ukraine. I show that despite the wide-ranging constraints imposed after the Revolution on the upper executive, the security of property rights declined. Theoretically, the article argues that the link between sovereign commitment and secure ownership hinges on vertical accountability in the state apparatus. While institutionalizing commitment by the presidency, the Revolution simultaneously exacerbated principal-agent dilemmas within the bureaucracy. Methodologically, the article contributes by triangulating available historical narratives and cross-national quantitative studies. Instead, the focus on one contemporary developing country and the use of qualitative process tracing dissects sovereign commitment and shows the mechanisms through which it can be subverted at lower administrative levels. Sixty-four semi-structured interviews with entrepreneurs and government officials from six Ukrainian regions, as well as analysis of the local media, provide the data.  相似文献

In the beginning of the internet age, companies were confronted with sometimes contradictory expectations regarding the use of e-business technologies. Using the concept of decoupling from new institutionalistic organization theory, the article examines under what conditions companies chose a decoupling strategy. In this way, the study aims to expand the empirical knowledge about decoupling processes and contribute to the new institutionalist theory debate on forms and conditions of strategic responses to institutional requirements. On the basis of data collected in 2002, influences on decoupling are analyzed by means of multivariate methods. The findings show that the choice of a decoupling strategy is influenced by external and internal factors as well as by the characteristics of the institutionalized model itself. They support the thesis that institutional constraints are actively processed by actors based on existing structures.  相似文献

This paper addresses the impact of the number and timing of panel waves in campaign panel surveys on findings concerning the prevalence of early, campaign, and late deciding as well as on the determinants of the time of voting decision. Using data from a seven-wave online campaign panel survey conducted during the 2009 German federal election, we demonstrate that the number and timing of panel waves affect results concerning the time of voting decision considerably. Whereas the number and timing of panel waves strongly affect the marginal distribution of decider types they do not impinge heavily upon the determinants of the time of voting decision.  相似文献
