Gunshot injury caused by a training bullet]

In the course of a scuffle a 50-year old man has been shot by a revolver. The culprit and witnesses state, there has been only one shot, whereas the victim declared having been shot twice. The medico-legal investigation revealed a gunshot wound that passed through the left thigh, a grazing shot of the right hand and a superficial lesion of the skin at the forehead with sprinkled gunshot residue in the epidermis. The investigation confirmed the statement of the victim: the first shot to the forehead was caused by a plastic training cartridge, the second to the right hand and thigh by a cartridge loaded with an ordinary bullet.     

Bite mark documentation and analysis: the forensic 3D/CAD supported photogrammetry approach

Bite mark identification is based on the individuality of a dentition, which is used to match a bite mark to a suspected perpetrator. This matching is based on a tooth-by-tooth and arch-to-arch comparison utilising parameters of size, shape and alignment. The most common method used to analyse bite mark are carried out in 2D space. That means that the 3D information is preserved only two dimensionally with distortions. This paper presents a new 3D documentation, analysis and visualisation approach based on forensic 3D/CAD supported photogrammetry (FPHG) and the use of a 3D surface scanner. Our photogrammetric approach and the used visualisation method is, to the best to our knowledge, the first 3D approach for bite mark analysis in an actual case. The documentation has no distortion artifacts as can be found with standard photography. All the data are documented with a metric 3D measurement, orientation and subsequent analysis in 3D space. Beside the metrical analysis between bite mark and cast, it is possible using our method to utilise the topographical 3D feature of each individual tooth. This means that the 3D features of the biting surfaces and edges of each teeth are respected which is--as shown in our case--very important especially in the front teeth which have the first contact to the skin. Based upon the 3D detailed representation of the cast with the 3D topographic characteristics of the teeth, the interaction with the 3D documented skin can be visualised and analysed on the computer screen.     

Changes in skeletal muscles in death caused by hypothermia

The review of 32 deaths resulting from hypothermia yielded mostly the common pathological findings as bright red livores, haemolytic frost marks of the skin and Wichnewski erosions of the gastric mucosa. In addition the muscle system of the body core (musc. ileopsoas) showed hemorrhages and histologically necrosis of its fibres in form of segmental and discoid sarcoplasmatic alteration. These changes are a quite specific sign of death due to hypothermia, as far as mechanical injury can be excluded. For best result however a special autopsy technique and an appropriate histological staining are advisable.     

Different worlds of contention? Protest in Northwestern,Southern and Eastern Europe

Despite the voluminous literature on the ‘normalisation of protest’, the protest arena is seen as a bastion of left-wing mobilisation. While citizens on the left readily turn to the streets, citizens on the right only settle for it as a ‘second best option’. However, most studies are based on aggregated cross-national comparisons or only include Northwestern Europe. We contend the aggregate-level perspective hides different dynamics of protest across Europe. Based on individual-level data from the European Social Survey (2002–2016), we investigate the relationship between ideology and protest as a key component of the normalisation of protest. Using hierarchical logistic regression models, we show that while protest is becoming more common, citizens with different ideological views are not equal in their protest participation across the three European regions. Instead of a general left predominance, we find that in Eastern European countries, right-wing citizens are more likely to protest than those on the left. In Northwestern and Southern European countries, we find the reverse relationship, left-wing citizens are more likely to protest than their right-wing counterparts. Lessons drawn from the protest experience in Northwestern Europe characterised by historical mobilisation by the New Left are of limited use for explaining the ideological composition of protest in the Southern and Eastern European countries. We identify historical and contemporary regime access as the mechanism underlying regional patterns: citizens with ideological views that were historically in opposition are more likely to protest. In terms of contemporary regime access, we find that partisanship enhances the effect of ideology, while ideological distance from the government has a different effect in the three regions. As protest gains in importance as a form of participation, the paper contributes to our understanding of regional divergence in the extent to which citizens with varying ideological views use this tool.     

Dental CT imaging as a screening tool for dental profiling: advantages and limitations

The use of dental processing software for computed tomography (CT) data (Dentascan) is described on postmortem (pm) CT data for the purpose of pm identification. The software allows reconstructing reformatted images comparable to conventional panoramic dental radiographs by defining a curved reconstruction line along the teeth on oblique images. Three corpses that have been scanned within the virtopsy project were used to test the software for the purpose of dental identification. In every case, dental panoramic images could be reconstructed and compared to antemortem radiographs. The images showed the basic component of teeth (enamel, dentin, and pulp), the anatomic structure of the alveolar bone, missing or unerupted teeth as well as restorations of the teeth that could be used for identification. When streak artifacts due to metal-containing dental work reduced image quality, it was still necessary to perform pm conventional radiographs for comparison of the detailed shape of the restoration. Dental identification or a dental profiling seems to become possible in a noninvasive manner using the Dentascan software.     

Why accommodate minorities asymmetrically? A theory of ideological authority insulation

Tensions between regionalist claimants and state-wide governments remain the primary source of violent conflicts. Existing theories cannot systematically explain why and when state-wide governments accede to such claims. Building on the partisan approaches developed so far, a theory of ideological authority insulation is constructed in this article. It is argued that the willingness of state-wide parties to transfer authority to specific territorial entities is predominantly informed by ideological proximity to those entities. In a nutshell, the dominant conflict dimension in a country superimposes partisan rationales on the territorial dimension. A new dataset has been compiled with roughly 4,300 region-cabinet dyads between 1945 and 2015, including electoral data, party positions and regional ‘centres of gravity’. Using panel rare-events regressions, it is found that ideological proximity systematically explains the accommodation of minority demand controlling for alternative explanations from the partisan and ethnic conflict literature. The empirical evidence therefore supports adding ideological insulation and superimposition to the toolbox of partisan and conflict researchers. Additionally, the findings encourage the application of arguments from the conflict literature in established democracies and the testing of insights from partisan researchers in less democratic environments.     

Homicide-suicide and other violent deaths: an international comparison

Homicides followed by the suicide of the perpetrator constitute a serious form of interpersonal violence. Until now no study has directly compared homicide-suicides to other violent deaths from multiple countries, allowing for a better understanding of the nature of these violent acts. Using country-specific data, this study describes and compares the incidence and patterns of homicide-suicide as well as the relationship between homicide-suicide, homicide, suicide and domestic homicide in the Netherlands, Switzerland and the United States. The results indicate that cross-nationally, homicide-suicides are more likely than other types of lethal violence to involve a female victim, multiple victims, take place in a residential setting and to be committed by a firearm. Although homicide-suicides display many similarities across the different countries, differences exist regarding age and the use of firearms in the offence. This study indicates that homicides followed by suicides differ from both homicides and suicides in similar ways internationally. Cross-national differences in the availability of firearms may explain the international variation of homicide-suicide rates and patterns.     

Accounting for Changing Earnings Inequality in Costa Rica, 1980–99

After declining from the mid-1970s to the mid-1980s, inequality in monthly earnings in Costa Rica stabilised from 1987 to 1992 and then increased from 1992 to 1999. In this article, we use recently developed techniques to measure the extent to which these changes in earnings inequality were the result of changes associated with the distributions of personal and workplace characteristics of workers or the earnings differences associated with those characteristics. We present evidence that the most important cause of the fall in inequality prior to 1987 was a decline in returns to education. Inequality stopped falling in Costa Rica in the 1990s in part because returns to education stopped falling. The most important cause of rising inequality in monthly earnings in the 1990s was an increase in the proportion of workers working a non-standard work week (part-time or over-time).
