Experimental tests for the validation of active numerical human models

The development of numerical human models is a topic of current interdisciplinary research. In the field of automotive safety these models can be applied for the optimization of protection systems. In forensic research human models can be used for the investigation of injury mechanisms and for the prediction and reproduction of injury patterns. However, up to now human models have been validated on the basis of PMHS tests without considering the effects of muscle activity. This paper shows two experimental volunteer test set-ups for the generation of experimental validation data. In a pendulum set-up the influence of muscle activity on the human kinematics was investigated. A drop test set-up was developed for the analysis of the effects of muscle activity on impact response characteristics of muscle tissue. Experimental results, presented in this paper, can be used for the validation and optimization of active numerical human models.     

Zwischen „der Eurokratie“ und „den Leuten“: Zum Problem der professionellen Vermittlung von Europapolitik

EU politics is strongly shaped by the activities of experts and professional actors with special knowledge of EU-specific rules, standards, semantics and institutional procedures. These EU professionals serve as important transmitters and brokers of European affairs in national contexts. They bundle and represent interests, provide information on EU policy proposals or support local and national organizations in their attempts of obtaining EU funding. In this way, these specialized actors have an important intermediary position between the “Eurocracy” and national citizenries as well as local addressees of EU policymaking. Building on classical and contemporary sociological discussions on the problem of professionalization in politics and on interview data the article analyzes the activities of these actors and scrutinizes what particular practices and strategies of interest mediation and policy transfer look like. What types of transmission and mediation can be found? Can EU professionals really be regarded as mediators and transmitters between European and local interests, or should they rather be seen as a relatively closed and self-referential group of specialists using their special competences mainly for their own sake and for positioning themselves within closed expert circles? Which difficulties and limitations can be seen with regard to practices and strategies of mediation in contemporary EU affairs?     

Optimal Dental Age Estimation Practice in United Arab Emirates’ Children

The aim of the study was to detect whether the Willems model, developed on a Belgian reference sample, can be used for age estimations in United Arab Emirates (UAE) children. Furthermore, it was verified that if added third molars development information in children provided more accurate age predictions. On 1900 panoramic radiographs, the development of left mandibular permanent teeth (PT) and third molars (TM) was registered according the Demirjian and the Kohler technique, respectively. The PT data were used to verify the Willems model and to develop a UAE model and to verify it. Multiple regression models with PT, TM, and PT + TM scores as independent and age as dependent factor were developed. Comparing the verified Willems‐ and the UAE model revealed differences in mean error of ?0.01 year, mean absolute error of 0.01 year and root mean squared error of 0.90 year. Neglectable overall decrease in RMSE was detected combining PM and TM developmental information.     

Classifying political regimes revisited: legitimation and durability

This article presents a new typology and a new dataset of political regimes (1946–2010). The classification presented is based, in theoretical terms, on the distinctive patterns of legitimation exhibited by the political regimes. To demonstrate the usefulness of the classification, I explore the extent to which the classification and its theoretical foundation, namely the pattern of legitimation, helps to explain the durability of different political regime types. I compare the results and explanations with those of Geddes and Hadenius and Teorell in order to clarify the differences made by the use of the presented classification.     

Clinically Detectable Dental Identifiers Observed in Intra‐oral Photographs and Extra‐oral Radiographs,Validated for Human Identification Purposes

Screening the prevalence and pattern of dental identifiers contributes toward the process of human identification. This research investigated the uniqueness of clinical dental identifiers in photographs and radiographs. Panoramic and lateral cephalometric radiographs and five intra‐oral photographs of 1727 subjects were used. In a target set, two observers examined different subjects. In a subset, both observers examined the same subjects (source set). The distance between source and target subjects was quantified for each identifier. The percentage of subjects in the target set being at least as close as the correct subject was assessed. The number of molars (34.6%), missing teeth (42%), and displaced teeth (59.9%) were the most unique identifiers in photographs and panoramic and lateral cephalometric radiographs, respectively. The pattern of rotated teeth (14.9%) was the most unique in photographs, while displaced teeth was in panoramic (37.6%) and lateral cephalometric (54.8%) radiographs. Morphological identifiers were the most unique, highlighting their importance for human identifications.     

A comparative analysis of media reports of U.S. parricide cases with officially reported national crime data and the psychiatric and psychological literature

This article is a content analysis of 150 unique cases of children killing parents in the United States as reported in the electronic news media. The accuracy of online coverage of U.S. parricide incidents is assessed using two types of resources: officially reported national statistics on known parricidal incidents and the psychological and psychiatric literature on matricide and patricide. Comparisons of news accounts of media-reported U.S. parricide cases with Supplementary Homicide Report data indicate that electronic media coverage of parricide cases focused on the more sensational and unusual parricides. Analyses of these media accounts by offender age found 13 significant differences between juvenile and adult offenders. Ten of these 13 differences related to motive and Heide's parricide offender types (severely abused, severely mentally ill, and dangerously antisocial) and were consistent with the mental health-related literature in this area. The limitations and directions for future research are discussed at length.
