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.     

The price of non-compliance with the Kyoto Protocol: The remarkable case of Norway

One of the ways to induce compliance is for an international enforcement mechanism to authorize the use of punitive consequences against a non-compliant country. However, such consequences should not cause significant damage to other (compliant) countries. The compliance mechanism of the Kyoto Protocol fails to meet this requirement. The Enforcement Branch of the Compliance Committee is instructed to impose punitive consequences on a non-compliant country that will have considerable adverse welfare effects for compliant countries as well. Using a numerical model, we show that in the case of Norway, the welfare effects can actually be worse if another country is punished than if Norway itself is punished.

Three Faces of Constituency Campaigns in Mixed-Member Electoral Systems. Parties and Candidates in Germany, 2005–13

Constituency campaigns are multidimensional and complex: parties and candidates are deeply entangled, and, at least in mixed-member electoral systems, local constituency campaigns are embedded within national party campaigns. Recent discussions have focused on aspects of campaign change in European democracies, especially disentanglement in terms of individualisation, personalisation, and/or localisation. This study contributes to the discussion both conceptually and empirically. Conceptually, three dimensions (‘faces’) of constituency campaigns are differentiated: organisational partyness, vertical integration, and communicative personalisation. This threefold differentiation allows for a more precise analysis of campaign patterns by differentiating party–candidate (organisation, communication) and intra-party (vertical integration) aspects. Constituency campaigns in the 2005, 2009, and 2013 German federal elections are empirically examined. The analysis explains why candidates decide for one or another campaign pattern. These three faces are empirically distinct as well. Furthermore, we argue that parties remain vital for the organisation of campaigns despite a decline in centralisation. Addressing the communicative face, the analysis shows that candidate-related issues are important, but a mix of party- and candidate-related communication gains importance.     

Participatory community analysis: identifying and addressing challenges to Ethiopian smallholder livelihoods

In 2012, Africa RISING conducted participatory community analysis (PCA) as the first phase of a participatory development approach in the Ethiopian highlands. The PCA identified trends, constraints, and opportunities – and shed light upon how farmers perceive livelihoods to be changing. Inputs, diseases, pests, soil fertility, post-harvest management, and fodder shortages were seen as challenges, while off-farm income has become increasingly important. Gender differences in livestock and crop preferences for food security and income sources were observed. PCA established development priorities in a way that researchers may have approached differently or missed, providing research development priorities for Africa RISING scientists.
