The article reviews findings on neighbourhood effects. First, methodological problems, such as the choice of spatial units, selection bias and social mechanisms are discussed. To overcome the problem of varying lists of neighbourhood effects, I suggest a methodological distinction between characteristics of the neighbourhood and social mechanisms. In the following section, these typologies are applied to analyse findings from empirical studies on topics such as the impact of the physical environment, perceived social capital and income. The complex relationship between neighbourhood characteristics and individual outcomes is then examined using studies on the impact on physical and mental health.Several research problems, such as the impact of different contexts on individuals of the same status are outlined in the following section. In the final chapter major findings are resumed and suggestions for further research are made.     

Grenzen der Meritokratie oder warum Quotenregulierungen sinnvoll sind

Economic theory has shown that economic discrimination can not persist for longer periods due to the intervention of market mechanisms. In contrast to this view, this article will demonstrate by using a theoretical model that in typical selection situations the practice of admitting persons to educational institutions while strongly discriminating against a particular group of applicants does not affect important success indicators of those educational institutions. As this observation also holds true under very general circumstances with respect to test reliabilities and distributional assumptions, it therefore can be used as a theoretical basis for many empirical investigations of persisting discrimination in non-economic spheres and for a general critique of meritocratic selection procedures.     

How Dare to Demand This from Volunteers! The Impact of Illegitimate Tasks

The present study examined the effect of illegitimate tasks (Semmer et al. Appl Psychol Int Rev 59:70–96, 2010) within the volunteer context. A total of 191 Red Cross volunteers were surveyed to reveal the impact of unreasonable and unnecessary tasks on the volunteers’ work engagement and intent to remain at the non-profit organization (NPO). To shed light on the process through which illegitimate tasks affect outcomes, the mediating role of self-determined motivation was explored. Furthermore, the volunteers’ role orientation was assumed to moderate the relationship between illegitimate tasks and outcomes. The results showed that unreasonable tasks directly decreased the volunteers’ intent to remain. Unnecessary tasks, in contrast, had a more subtle effect in that they reduced the self-determined motivation of volunteers. Also, evidence was found for the moderating influence of the volunteers’ role orientation: Whereas unreasonable tasks were equally harmful for both groups, unnecessary tasks more strongly affected those volunteers who expressed more organizational ownership.     

The Implementation of Voting from Abroad: Evidence from the 2014 Turkish Presidential Election

Voting from abroad (VFA) is a complex norm and practice due to the multilevel processes, structures and actors involved. This article explores the reasons behind the eventual adoption of this practice within the context of a long and well‐known history of emigration in Turkey. During the 2014 Turkish presidential election, emigrants from Turkey were finally allowed to participate from abroad even though legislation giving them this right has been in place since 1995. Based on archival research and fieldwork in Germany and the United States, this article discusses the varying relevance of three central explanatory factors to the implementation of VFA: emigrant lobbying, the electoral expectations of potential benefit by the governing party, and the presence of broader, state‐led diaspora engagement policies. The first of these is important but insufficient, whereas the second factor is necessary. Moreover, the presence of broader, state‐led diaspora engagement policies is a mediating factor. This article finds that specific actors like political parties may play the crucial role, highlighting the need for critical examination of their role in the implementation process.     

Das Rätsel der Retraditionalisierung – Zur Verweiblichung von Elternschaft in GeburtsvorbereitungskursenThe feminization of parenthood: about the traditionalizing effects of prenatal classes

Our paper examines the significance of prenatal classes for the formation of a gendered division of labour. We argue that prenatal classes, which have hitherto largely been disregarded in sociological research, stand in the tradition of a substantially older form of institutionalized mother schooling, whose primary goal was the gendered assignment of childcare. Using explorative observations and content analysis as research methods we find that in recent prenatal classes gender differences are highlighted through the class structure, interconnected with gendered attributions of domestic labour, and legitimized through a process of scientifically supported naturalization. Thus, our ethnographic analysis shows that prenatal classes introduce and support the notion of a gendered division of labour and thereby function as institutions of re-traditionalization.     

Tax incentives and family labor supply in Austria

The family policy reform 2009 introduced tax deductibles for children and child care expenditures in Austria. In this paper we evaluate this reform based on a structural labor supply model with unitary households which has been estimated on the European Statistics on Income and Living Conditions cross-sections 2004–2008. We find that the reform had only small employment effects, most of them being generated through the introduction of a child care deductible. However, to illustrate the employment potential of a shift from universal child transfers to tax deductibles we propose additional simulations showing that such a policy shift would yield an increase in full time equivalents of approximately .70 % of overall employment, with married females increasing their labor supply by up to 1.5 %. While the proposed policy shifts have regressive effects in terms of their distributional impact, we show that phasing-out the tax deductible at higher income allows for the compensation of lower-income households without jeopardizing positive employment effects.     

Evolutionarily Stable Co-operative Commitments

If contracts cannot be fully specified Pareto optimal results may be closed off because individuals cannot rationally trust each other's promises. This paper assumes that human individuals can become internally committed not to act opportunistically and that others can detect to a certain extent whether they are dealing with an uncommitted (untrustworthy) or a committed (trustworthy) partner. Adopting an `indirect evolutionary approach' we show that co-operative commitments can survive in evolutionary competition even if conventional mechanisms like repetition, reputation, contract or promising are lacking. If detection of uncommitted individuals is neither too costly nor too unreliable there will in general be a `niche' for both committed and uncommitted actors even in one off large numbers' interactions.     

Reflections Regarding Future Cannabis Use Among High‐Frequency Users in a Canadian University Student Population

Cannabis is the most widely used illicit drug worldwide, and the most commonly used illicit drug in Canada, among postsecondary student populations. This cross‐sectional study qualitatively assessed 112 high‐frequency, cannabis‐using university students in Canada: It examined their subjective expectations regarding what they anticipated their cannabis use would look like in the short‐ and mid‐term future and explored factors they saw potentially contributing to changes in their prospective drug use. Results indicated that participants believe that decisions about future cannabis use will be influenced by several contextual factors, including education and employment responsibilities, intimate relationships, and peer associations. These findings help illuminate the natural evolution of cannabis use and can guide the development of interventions for high‐frequency cannabis users in the future.     

Orphans at risk in sub-Saharan Africa: evidence on educational and health outcomes

Based on comparable data for eleven sub-Saharan African countries with especially high rates of orphanhood, we examine how orphanhood affects children’s educational and health outcomes. Using household fixed-effects to control for influences at the household level, we show that orphans do not only fare worse than non-orphans because they tend to live in poorer households, but that they are also at a disadvantage compared to non-orphans within the same household. They lag behind in education and are more often malnourished and stunted. (The coefficients on the health outcomes are only statistically significant for some of the countries and some of the health measures, however.) Moreover, we show that non-orphaned children not living with a biological parent are also worse off compared to biological children of the same caregivers. Educational gaps are particularly evident for children whose mother is deceased or absent. The additional effect of paternal death or absence is rather modest or insignificant in most countries.     

Alcohol consumption and risky sexual behavior among young adults: evidence from minimum legal drinking age laws

This paper exploits the discrete jump in alcohol consumption at the minimum legal drinking age (MLDA) in the USA and uses a regression discontinuity design to investigate the relationship between drinking and risky sexual behaviors among young adults. Using confidential data from the National Longitudinal Survey of Youth (1997 Cohort), we document that young adults tend to drink up to 2.1 days more once they are granted legal access to alcohol at age 21. Although the discrete jump in alcohol consumption at the MLDA is associated with an increase in the probability of having sex by up to 7.8 percentage points, it does not have a significant impact on the probability of engaging in risky sexual behaviors among young adults. We also document that the effect of the MLDA on the probability of using several different birth control methods is not significant for those who had sex in the past 4 weeks. These results are robust under alternative specifications and imply that although the MLDA law is quite effective in reducing alcohol consumption among young adults, spillover effects of this law on risky sexual behaviors are relatively limited.
