The article describes the case of a 29-year-old woman who was found dead in her apartment on a bar stool with the body being maximally retroflected in the lumbar region, the head hanging down and the feet and hands barely touching the floor. On external inspection of the body the cuff-like distribution of hypostasis on the forearms and lower legs was consistent with the position in which the body was found. There were no signs of foreign intervention. At autopsy massive congestion was found in the internal organs as well as pulmonary and cerebral edema. In the ventral region of the lumbar intervertebral discs superficial hemorrhages were detected. The alcohol content was 3.40 per thousand in the blood and 4.43 per thousand in the urine. As the essential pathogenetic mechanisms responsible for death reduced venous reflux to the heart in combination with postural asphyxia and the influence of alcohol are discussed.  相似文献

If mobile content is going to be a success, it is important that the content provided to the end users is of high quality and that it creates value for the end users. Therefore, it is important that the content producers can protect their copyrights in order to be able to earn money on the production of high value content. Due to “Everything-over-IP” (i.e. a single Internet Protocol platform for both voice and data traffic) and convergence, including the extension of the media sector to the mobile sector, more distribution channels are made available for content. In this situation, DRM can play an important role as it enables the content producers to better control and bill their content although it is distributed over several different distribution channels and networks.This paper looks at the possibilities of DRM for the development of mobile content markets. It will in detail look at the current legal problems and possibilities that are associated with DRM and mobile content, i.e. the national borders due to national legal systems, the harmonisation at EU level, the problems with copies for personal use, the enabling of control over copyrights and the legal protection of DRM systems. Based on the analysis of the legal situation, the outcomes on the development of mobile content markets are analysed.  相似文献

This paper seeks to reveal the institutional interests of the Council of Ministers, the European Parliament and the Commission in the comitology system. This is done by an investigation of the 2006 comitology reform, which introduced the regulatory procedure with scrutiny. This reform was the result of developments in four areas: the Lamfalussy reform in the area of financial regulation; the controversial use of comitology in the area of GMOs, food safety and the environment; the failed Constitutional Treaty; and the amending of the 1999 comitology decision. The analysis shows that the reform was the result of a two‐dimensional constitutional struggle. The first dimension concerns the relative supervisory position of the two legislative actors, the Council and the European Parliament. The second dimension concerns the relationship between the legislative and the executive branch of the EU system. In theoretical terms, the analysis demonstrates an example of T.M. Moe's ‘politics of structural choice’. The paper ends by drawing lessons for the negotiations on the new comitology system following the Lisbon Treaty.  相似文献

In recent years, a widespread consensus has emerged about the necessity of establishing bridges between quantitative and qualitative approaches to empirical research in political science. In this article, we discuss the use of the synthetic control method as a way to bridge the quantitative/qualitative divide in comparative politics. The synthetic control method provides a systematic way to choose comparison units in comparative case studies. This systematization opens the door to precise quantitative inference in small‐sample comparative studies, without precluding the application of qualitative approaches. Borrowing the expression from Sidney Tarrow, the synthetic control method allows researchers to put “qualitative flesh on quantitative bones.” We illustrate the main ideas behind the synthetic control method by estimating the economic impact of the 1990 German reunification on West Germany.  相似文献

The article explores the extent, the institutional mechanisms and economic consequences of economically motivated bribery in the Norwegian (and British) oil industry. It focuses on corruption directed against middle-level management in the oil companies. The empirical part of the study is partly based on public information collected from court cases, mainly from British courts; and partly based on systematic interviews of security experts in Norwegian and international oil companies, and British and Norwegian police.  相似文献

As European majority members are often hostile toward ethnic minorities, it is important to identify sources that reduce opposition to immigrants. First, focusing on Denmark, this article examines whether intergroup contact influences attitudes toward ethnic minority rights (henceforth: ‘ethnic tolerance’). Second, this study tests whether the contact‐tolerance relationship is mediated by self‐disclosure and symbolic threat. Furthermore, contact is measured as workplace contact in order to reduce self‐selection biases. The empirical tests are performed on a Danish high‐quality national probability sample from 2009 (N = 1,929). Analysis shows that intergroup contact generates ethnic tolerance because workplace contact weakens threat perceptions and stimulates disclosure of personal information. Generally, these results suggest that regular intergroup contact can improve ethnic relations in contemporary democracies.  相似文献

Criminal recidivism was studied during 2 years in a Swedish population-based cohort (N = 318) of mentally disordered male offenders who had undergone a pretrial forensic psychiatric investigation, been convicted in subsequent trials, and been sentenced to forensic psychiatric treatment (FPT; n = 152), prison (n = 116), or noncustodial sanctions (n = 50). Recidivism was analysed in relation to index sanctions, levels of supervision, diagnoses, and criminological factors. Significantly lower recidivism in the FPT group was related to lower crime rates during periods at conditional liberty in this group alone, and recidivism was significantly more common among offenders with at least one of the two diagnoses of substance abuse disorder and personality disorder than among those with psychotic or other mental disorders alone. Age at index crime and number of previous crimes emerged as significant predictors of recidivism. The results of this study suggest that the relapse rates depend as much on level of supervision as on individual characteristics.  相似文献

Accidental or deliberate poisoning of food is of great national and international concern. Detecting and identifying potentially toxic agents in food is challenging due to their large chemical diversity and the complexity range of food matrices. A methodology is presented whereby toxic agents are identified and further characterized using a two-step approach. First, generic screening is performed by LC/MS/MS to detect toxins based on a list of selected potential chemical threat agents (CTAs). After identifying the CTAs, a second LC/MS analysis is performed applying accurate mass determination and the generation of an attribution profile. To demonstrate the potential of the methodology, toxins from the mushrooms Amanita phalloides and Amanita virosa were analyzed. These mushrooms are known to produce cyclic peptide toxins, which can be grouped into amatoxins, phallotoxins and virotoxins, where α-amanitin and β-amanitin are regarded as the most potent. To represent a typical complex food sample, mushroom stews containing either A. phalloides or A. virosa were prepared. By combining the screening method with accurate mass analysis, the attribution profile for the identified toxins and related components in each stew was established and used to identify the mushroom species in question. In addition, the analytical data was consistent with the fact that the A. virosa specimens used in this study were of European origin. This adds an important piece of information that enables geographic attribution and strengthens the attribution profile.  相似文献
