National Identities and Mass Belief Systems on Foreign and Security Policy in Germany

The article analyses how German citizens' national identities are linked to their belief systems regarding foreign and security policy. Previous research has pointed out that citizens' belief systems are not unconstrained, but organised hierarchically. Especially domain-specific predispositions have been shown to structure policy attitudes. Against the backdrop of the prominence national history is granted in public discourse, the article argues that in Germany national identities influence both predispositions and attitudes concerning foreign and security policy. Using data from a representative telephone survey of German adults, a structural equation model is used to test this hypothesis. The results show that different types of national identities have distinct effects on domain-specific predispositions and attitudes towards the German participation in the ISAF mission in Afghanistan.     

Laminated safety glass as an intermediate target: a wound ballistic study

Various 9‐mm ammunitions (A1, A4, A5, ST, GS, GSb, P.E.P., SeCa, HP, PTP/s, VM, McVG, DM41, PTP, SX2, PT, and MEN frangible) were tested regarding their velocity, energy, angle of impact, and potential wound channel after penetrating a car window at 30° and 90°. Test materials were gelatine, soap, and pig cadavers. The velocities of the projectiles were between c. 288 and 430 m/ses, the energy spread between 394 and 564 J. Handgun bullets fired through vehicular side window glass lose substantial energy reducing the effectiveness of the ammunition. This effect is greater when fired at an angle of 30° compared to 90°. At a shooting angle of 90°, none of the different projectiles showed remarkable differences considering its wound ballistic features. Accuracy is maintained at a 90° angle but seriously impaired at 30°. None of the examined ammunition complied with the demanded wound channel effectiveness of 30–60 J/cm.     

Invalid Voting in German Constituencies

This article studies invalid voting, which has received very little attention so far, given the broad interest and substantial relevance of voting behaviour research. Existing evidence is mostly limited to rather specific and hardly representative countries. Yet, the extent of invalid ballots is not negligible. Despite undemanding electoral rules, more invalid votes are cast in German general elections than votes for niche parties. Against this backdrop, the article describes prevalence of invalid voting in the mixed electoral system of Germany and tests explanations of its variation between constituencies. Analysing data from the most recent Bundestag Election, results give clear support to politico-institutional explanations: voters are more willing to waste their vote if second-order elections are held concurrently. Specifically under the plurality rule, more (first) votes are wasted if there are large shares for parties without direct candidates and many competing candidates.     

The Meaning of Students’ Personal Belief in a Just World for Positive and Negative Aspects of School-Specific Well-Being

In two cross-sectional questionnaire studies with N = 1792 German and Indian students, aged between 12 and 17 years, we investigated the relation between personal belief in a just world (BJW) and positive as well as negative dimensions of school-specific well-being. Furthermore, we considered students’ personal experience of teacher justice as possible mediator in this relation and controlled for confounding effects of gender, neuroticism, and locus of control. In Study 1, we used multilevel modeling to analyze the German data and to control for class-level effects. In accordance with our hypotheses, Study 1 showed that the more students believed in a personal just world, the better their positive attitudes toward school, their academic self-esteem, and their enjoyment in school were, and the less somatic complaints in school, social problems in school, and worries toward school they experienced. These associations partly differed between classes, but generally persisted when controlled for sex, neuroticism, and locus of control. Finally, the association between personal BJW and well-being was at least partly mediated by students’ personal experience of teacher justice. In Study 2, we focused on the generalizability of the pattern of results across different cultural contexts. However, we did not aim to carry out comparative research. Results from bootstrap mediation analyses were predominantly the same as in Study 1. The adaptive functions of BJW and implications for future school research are discussed.     

Individual Ambidexterity and Performance in the Public Sector: A Multilevel Analysis

In this study, we examine individual ambidexterity (i.e., individuals’ balanced pursuit of exploitative and explorative activities) in a public management context. In particular, we combine survey data from junior scholars and secondary data from the Center for Higher Education to investigate the role of individual ambidexterity in an academic context. We conduct multilevel analyses and find that individual ambidexterity is positively related to research performance, indicating that individual ambidexterity positively influences individual performance in the public sector. In addition, we observe a negative relationship between the supervisory ratio and research performance, indicating that having a lower number of employees supervised by a single person leads to lower performance in the public sector.     

Security as Socio‐Technical Practice: Predictive Policing and (Non‐)Automation

Predictive policing is among the most prevalent new technological tools for law enforcement. Understanding how the police produce knowledge about crime and society in technologically mediated ways is important vis‐a‐vis practices of social ordering. In this paper, I suggest to draw on literature from Science and Technology Studies (STS) in order to understand the impact of technology not as analytically isolated artefact, but as embedded in socio‐technical relations that define how it comes to matter in everyday practice. In order to demonstrate what it means to think about technology in socio‐technical terms, I engage the discrepancy between the technical capacities of predictive policing applications and the ways in which they actually become part of police work on a daily basis. Specifically, I investigate how claims about the automation of crime analysis in predictive policing are reconfigured through the interplay of social and technical elements in police work.     

Macroscopical estimation of the post mortem interval (PMI) and exclusion of the forensically relevant resting period--a comparison of data presented in the literature with recent osteological findings

The aim of the present study was to determine to what extent macroscopical parameters mentioned in the literature are suitable for the estimation of the post mortem interval (PMI) and particularly for the exclusion of the forensically relevant resting period for recent bone material. The macroscopical examination of recent bone material with a known PMI showed that only one published parameter (relics of adipocere in the cross section of the compacta) was consistent with our findings for this particular resting period (27-28 years). Other macroscopical parameters presented in the literature were contradictory to the results observed in this study. Among those are the rigidity of bones, the adhesion of soft tissue, the filling of the marrow cavity, and the permeation of the epiphyses with adipocere. Concerning the exclusion of the forensically relevant resting period, a similar result was observed. This study identified some diagnostic findings in bones with a resting period of less than 50 years which according to the literature should only be present after a resting period of more than 50 years. These features included the lack of macroscopical traces of adipocere, degradation of the compacta surface, detachment of the cortical substance, the ability of bone to be broken with bare hands, and superficial usures. Moreover, in one-third of our cases we identified some intra-individual differences not previously described in the literature. In addition to the other results, those intra-individual differences make an estimation of the PMI more difficult. However it should be noted that those published parameters were collected from bone material which was stored in a "relatively arid sand-grit-clay soil of the broken stone layer of Munich". The bones in the present study were stored in acidic and clayey-loamy soil, partly with lateral water flow. In conclusion, the present study demonstrates that one should use caution estimating the post mortem interval and excluding the forensically relevant resting period, even when all available results are considered.
