The dark side of the German ‘welcome culture’: investigating the causes behind attacks on refugees in 2015

In 2015, Germany experienced a record high influx of refugees – and received international praise for its ‘welcome culture’. At the same time, however, attacks on refugees rose to an alarming level. This article describes the distribution of these attacks and probes their causes, using detailed socioeconomic and political data while modelling a hierarchical data structure. Controlling for further relevant factors taken from the extant literature, the analysis first tests whether the strength of extreme right political parties plays a role and, second, it models a contagion effect, taking into account spatial as well as temporal proximity. The findings suggest that the strength of right-wing parties in a district considerably boosts the probability of attacks on refugees in that area. They also corroborate the idea of behavioural contagion. The set of social-structural variables employed as controls yielded only limited explanatory power.

Is there anything Left? The politics of social spending in new democracies

The evolution of public social expenditures displays divergent patterns across non‐western countries. This exploratory article argues that in order to understand the domestic sources of this divergence, institutional and structural explanations should be complemented with an actor‐oriented perspective. Analyses of the role of party politics in non‐OECD democracies, through multivariate fixed‐effect regressions using data from 46 countries between 1995 and 2015, reveals a robust positive association between shifts towards Left party government and increases in total public social expenditures, also when controlling for structural and institutional factors. This association however seems potentially conditional on sufficient levels of economic growth. While indicating an impact of partisanship, further research is arguably needed regarding the origins, organization and policy outputs of parties in more recently democratized countries, as well as regarding the conditions under which the ideological orientation of parties in government are actually consequential.     

Sexual dimorphism in human browridge volume measured from 3D models of dry crania: A new digital morphometrics approach

Sex estimation from the human skull is often a necessary step when constructing a biological profile from unidentified human remains. Traditional methods for determining the sex of a skull require observers to rank the expression of sexually dimorphic skeletal traits by subjectively assessing their qualitative differences. One of these traits is the prominence of the glabellar region above the browridge. In this paper, the volume of the browridge region was measured from digital 3D models of 128 dry crania (65 female, 63 male). The 3D models were created with a desktop laser scanner, and the browridge region of each 3D model was isolated using geometric planes defined by cranial landmarks. Statistical analysis of browridge-to-cranium volume ratios revealed significant differences between male and female crania. Differences were also observed between geographically distinct populations, and between temporally distinct populations from the same locale. The results suggest that in the future, sex determination of human crania may be assisted by quantitative computer-based volume calculations from 3D models, which can provide increased objectivity and repeatability when compared to traditional forensic techniques. The method presented in this paper can easily be extended to other volumetric regions of the human cranium.     

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.     

Towards a Measurement of Extreme Left-Wing Attitudes

Previous research on left-wing extremism relied largely on measurements that are unsuitable to detect and track extreme attitudes. In the absence of a clearly defined instrument for left-wing extremism, researchers based their predictions largely on indicators like voting behaviour or the left—right self-placement scale. Building on a large-scale investigation of data from the past 20 years, the paper shows that such indicators do not serve as adequate proxies, since those labelled as ‘extreme’ do not hold extreme attitudes in most cases. Analysing a variety of left-wing extremist attitudes across the past two decades shows that there is indeed a core set of attitudes that seem to resemble what we would call a traditional left-wing extremist identity. The paper suggests an instrument that can serve as a starting point for further developing an index of left-wing extremism. Finally, the potential of the extreme left is assessed using the constructed index. The results show that the estimated potential of the new measure differs substantially from conventional measurements, not in quantity but in its composition. As a result, traditional measurements fail to predict actual left-wing extremism. In particular, anti-pluralist mindsets are heavily neglected. Implications are thus discussed for Germany, and the world at large.     

Are School Committees a Source of Empowerment? Insights from Tanzania

Studies on user committees often critique the claim that membership to these committees empowers people. In this article, we use survey data on empowerment school committees in Tanzania to find out whether school committee membership is a source of empowerment of people at the local levels. Our findings suggest that membership in itself has limited impact on empowerment, while access to information and gender are the major sources of empowerment. However, the role of membership to the school committee is significant insofar as it can expose members to critical information on school issues.     

Justice Sensitivity and Cooperation Dynamics in Repeated Public Good Games

It is frequently observed that despite individual incentives to free ride, humans decide to cooperate with each other to increase social payoffs. In the current research, we address the effects of individual differences in justice sensitivity on cooperation. Using incentivized repeated public good games, we find that individual differences in justice sensitivity—the ease of perceiving, remembering, and reacting to injustice from the perspectives of an observer, beneficiary, or perpetrator, but not victim—substantially predicts cooperation in the absence of a punishment option. In contrast, when costly punishment is allowed for, cooperation becomes strategic as it also aims at avoiding subsequent punishment. If such a sanctioning mechanism is in place, justice sensitivity no longer predicts cooperation. The results regarding the degree of cooperation as reaction to initial non-cooperation of one’s counterparts highlight the role of justice-concerning personality traits for the sufficient provision of public goods, as sanctioning institutions are not always possible, effective, or suitable.
