Lethal Violence: A Global View on Homicide

As the most serious crime, homicide is both relevant and suitable for cross-national comparisons. The global homicide rate of ca. 6 per 100,000 people is an average of hugely diverging national rates ranging from 0.25 in Singapore to ca. 100 in El Salvador. The validity of global homicide statistics suffers from various differences in definitions as well as reporting and registration processes. Both criminal justice and causes of death statistics are used by the World Health Organization to construct rates, yet these are available only for a minority of countries. An overview on homicide in history and non-state societies shows that violence levels were considerably higher compared to those in today’s developed world and have dropped dramatically in Europe and North America during the early modern period. The rates first increased and then declined between ca.1960 and today in most developed nations in a synchronized manner, hinting at common influences. In recent years, homicide trends have shown a polarizing pattern, with increasing rates in Latin America and decreasing rates in most other world regions, especially East Asia and the Pacific, where rates have fallen below the European average concurrent with rising scores on the Human Development Index. Except in Eastern Europe, the frequency of homicide is strongly linked to the use of firearms, which account for 44% of homicide cases worldwide. Longitudinal studies have produced robust evidence for the pivotal role of deprivation and inequality in fostering lethal violence and of social welfare policies in reducing it. Although the transition to democratic political systems seems to increase homicide rates temporarily, the legitimacy of state institutions and the suppression of corruption are connected to lower homicide rates. Because of conceptual and methodological problems, questions concerning the generalizability of effects across space and time remain. Nevertheless, the research findings are sufficiently robust to draw important conclusions for violence prevention: reductions in poverty and income inequality, investments in welfare policies and gender equality, and improvements in the legitimacy of state institutions will help to bring homicide rates down

Old age and fear of crime: cross-national evidence for a decreased impact of neighbourhood disadvantage in older age

Fear of crime among older people has been a frequent topic in ageing research, criminology and urban studies. The ‘environmental docility hypothesis’ assumes that older people are more vulnerable to adverse neighbourhood conditions than younger age groups. Yet, few studies have tested this influential hypothesis using samples of respondents covering the complete adult lifespan. Looking at fear of crime, we investigated the person–environment interaction of age and neighbourhood disadvantage, using two independent surveys comprising 12,620 respondents aged 25–90 years residing in 435 neighbourhoods in four cities in Germany and Australia. We used multi-level analysis and cross-level interactions to model age-differential effects of neighbourhood disadvantage on fear. Contrary to the hypothesis, we found a weakening of neighbourhood effects on fear with age. The strong effect of neighbourhood disadvantage on fear of crime dropped by around half from the youngest (25 years) to the oldest age (90 years) in both countries. Younger people were almost as fearful as older people in the most disadvantaged neighbourhoods, but older people were considerably more fearful than younger ages in better-off neighbourhoods. We found limited empirical support for the assumption that this diminished association between neighbourhood disadvantage and fear can be explained by the stronger neighbourhood attachment of older people. The limitations of the analysis and potential future directions of research are discussed

In Their Own Hands: Young People and Self-Justice Retaliation in Germany

Strong and viable modern states have limited the use of private force to narrowly-defined situations of self-defense. Yet, evidence from crime surveys shows that a significant proportion of violent and property crimes is not reported to police. Instead of calling the police, people either take no action or employ a variety of mechanisms, including retaliation, to settle disputes. Drawing on data from a survey of 2,921 young people in two German cities, we investigate the propensity of adolescents to resort to self-justice retaliation. The results show widespread propensity to engage in retaliatory actions, particularly among adolescent males of low socio-economic status. Further, attitudes to the police, unsupervised routine activities, and delinquency-related variables were the most influential correlates of propensity to engage in retaliatory actions. </jats:p

Kriminalgeographie Baden-Württembergs (2003-2007) : Sozioökonomische und räumliche Determinanten der registrierten Kriminalität

Dieser Arbeitsbericht stellt wesentliche Ergebnisse des Forschungsprojekts "Regionalanalysen der registrierten Kriminalität" vor. Das Projekt nutzt die Daten der Polizeilichen Kriminalstatistik der Jahre 2003 bis 2007 für eine detaillierte Analyse der regionalen Verteilungen der Kriminalität in Baden-Württemberg auf der Ebene der Städte ab 20.000 Einwohner und der Landkreise. Zudem erfolgt eine kleinräumige Analyse der Tatverdächtigenbelastungsziffern in den über 1000 Gemeinden des Landes. Die Regressionsanalysen können detaillierte Aufschlüsse darüber geben, welche strukturellen Faktoren mit Belastungen unterschiedlicher Kriminalitätsformen in Beziehung stehen. Sowohl soziale Benachteiligungen als auch Gelegenheitsstrukturen sowie deren Wechselwirkungen sind für die Erklärung hoher Kriminalitätsbelastungen relevant. Die Untersuchung zeigt die große Bedeutung der Tätermobilität für die hohe Kriminalitätsbelastung in größeren Städten auf. Die Vielzahl der Ergebnisse aus den Modellrechnungen wird in diesem Bericht verständlich beschrieben und durch Karten und Graphiken anschaulich aufbereitet

Nanoparticle–membrane interactions

Engineered nanomaterials have a wide range of applications and as a result, are increasingly present in the environment. While they offer new technological opportunities, there is also the potential for adverse impact, in particular through possible toxicity. In this review, we discuss the current state of the art in the experimental characterisation of nanoparticle-membrane interactions relevant to the prediction of toxicity arising from disruption of biological systems. One key point of discussion is the urgent need for more quantitative studies of nano-bio interactions in experimental models of lipid system that mimic in vivo membranes
