Image-guided virtual autopsy findings of gunshot victims performed with multi-slice computed tomography and magnetic resonance imaging and subsequent correlation between radiology and autopsy findings

Because the use of radiology in modern forensic medicine has been, until today, mostly restricted to conventional X-rays, which reduces a 3D body to a 2D projection, a detailed 3D documentation of a gunshot's wound ballistic effects was not possible. The aim of our study was to evaluate whether the progress in imaging techniques over the last years has made it possible to establish an observer-independent and reproducible forensic assessment using multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) technologies for the documentation and analysis of gunshot wounds. The bodies of eight gunshot victims were scanned by MSCT and by MRI; the data of these imaging techniques were post-processed on a workstation, interpreted and subsequently correlated with the findings of classical autopsy. With the spiral CT and MRI examinations and the subsequent 2D multi-planar reformation (MPR) and 3D shaded surface display (SSD) reconstruction, the entire gunshot-created complex skull fractures and brain injuries (such as wound channels and deeply-driven bone splinters) could be documented in complete and graphic detail. CT and MRI also documented vital reaction to the gunshot by demonstrating air emboli in the heart and blood vessels and the classic pattern of blood aspiration to the lung. Gunshot residues deposited within and under the skin were visible. In conclusion, we think that the radiological methods of MSCT and MRI have the potential to become a routine "virtual autopsy" tool in the future. Bullets and relevant histological samples from specific sites then might be won in image-guided minimally invasive fashion via percutaneous biopsy. The rapid application of developing radiological methods may lead to new horizons in forensic documentation and intravital as well as postmortem examination.     

Discounting the benefits and costs of environmental regulations

This paper develops a two-stage procedure for discounting the benefits and costs of environmental regulations that is a variant of the shadow price of capital approach. Under this approach, the capital costs imposed by a regulation are annualized using the marginal rate of return on capital and then both benefits and costs are discounted using the social rate of time preference. This approach yields results that differ significantly from those of conventional discounting when benefits occur with a substantial lag or when benefits are long term.     

The personality of stealth democrats: how traits shape attitudes towards expert-based governments

While some scholars call for mechanisms to give citizens a greater voice in politics, others critically question the demand for more citizen participation. Rather, they find that the people do not want to be involved in politics and prefer independent experts to make political decisions. This perspective is captured by Hibbing and Theiss-Morse in their concept of stealth democracy. They describe stealth democrats as people who think that political debates are unnecessary or who naturally avoid all sorts of conflict. Especially the latter argument points to a potential psychological underpinning of stealth attitudes, which forms the starting point of the investigation here. This article evaluates the personality of stealth democrats and makes use of a well-known concept to capture personality traits, the ‘Big Five’ model. Analysing unique survey data from Switzerland, the results reveal significant relationships between personality traits such as conscientiousness, agreeableness, and neuroticism and stealth attitudes.     

Estimating damages from price-fixing: the value of transaction data

We use a unique private data set of about 340,000 invoice positions from 36 smaller and larger customers of German cement producers to study the value of such transaction data for an estimation of cartel damages. In particular, we investigate, first, how structural break analysis can be used to identify the exact end of the cartel agreement and, second, how an application of before-and-after approaches to estimate the price overcharge can benefit from such rich data sets. We conclude that transaction data allows such a detailed assessment of the cartel and its impact on direct customers that its regular application in private antitrust cases is desired as long as data collection and preparation procedures are not prohibitively expensive.     

“The Good,the Bad and the Ugly” Reconsidered: A Comparison of German,Canadian and Spanish Labour Migration Policies

This article compares three immigration countries that are perceived, both publicly and politically, as being fundamentally different: Canada, which is allegedly one of the most attractive destination countries for labour migrants worldwide; Germany, which is still thought to be sceptical towards immigration; and finally Spain, which is considered institutionally incapable of implementing efficient labour migration policies. Against the backdrop of various political reforms that have been adopted in these countries, however, the article argues that such a distinction is becoming increasingly inaccurate. This observation is backed empirically by analysing the technique of screening labour migrants and the temporal design of labour migration policy.     

The Discursive Construction of Terrorist Group Identity

The media coverage of terrorist acts has been the subject of numerous scientific studies. However, the terrorist groups’ own communication perspectives have not been thoroughly researched. The following article deals with terrorist groups and their use of websites for identity building. We examine the discursive construction of terrorist group identity through critical discourse analysis (CDA). The CDA of online texts from websites of terrorist groups is based on a five macro-strategy scheme. Our sample consists of six terrorist groups, with each group of two sharing different motivations: social-revolutionary, ethno-nationalist, or religious. All the groups analyzed are listed as terrorist organizations by the European Union. The CDA of 27 terrorist websites, purposively sampled, was conducted using two coders per site. Through this analysis, the researchers draw conclusions on strategies employed by terrorist organizations in building identity and how to counter their unregulated propaganda.     

Immunohistochemical proof of amelogenin in teeth--a contribution to the evaluation of the age in the identification of unknown corpses

When a corpse is found that cannot be identified, one of the forensic tasks is to determine how old the person was when she or he died. To solve this frequently asked question in forensic practice, the enamel protein amelogenin was marked immunohistochemically in 249 extracted teeth. Amelogenin is already produced during prenatal development and is gradually used up throughout life into old age. Hence, the demonstrability decreases with age. The extent of the labelling can be quantified by measuring the mean optical density (MOD). While it is not possible to determine the age on the basis of the mean optical density measurements alone, logistic regression of the MOD together with dichotomisation of the teeth according to age allows statements as to whether the person was younger or older than 30 years.
