Changes in HIV/AIDS knowledge and testing behavior in Africa: how much and for whom?

Demographic and Health Survey data from nine African countries make it clear that HIV/AIDS prevention knowledge has been increasing. Still, in many cases, fewer than half of adult respondents can identify specific prevention behaviors. Knowledge is lowest in rural areas and among women. HIV testing generally remains rare but is highly variable across countries, likely reflecting differences in the supply of testing services. In most cases, schooling and wealth impacts on prevention knowledge have either been stable or have increased; hence, in the majority of contexts, initial disparities in knowledge by education and wealth levels have persisted or widened.

Welfare analysis of a tax reform for Germany: a comparison of the unitary and collective models of household labour supply

We compare results of a tax reform analysis obtained with the collective and unitary models of household behaviour. We simulate real world micro-data by means of a collective approach, using a compound procedure of estimation and calibration based on the 1998 wave of the German socio-economic panel. We estimate a unitary model on this ‘collective’ data set. Investigating a move from joint to individual taxation on the basis of both models, we obtain important discrepancies between predicted adjustments to labour supply and distortions in the welfare analysis of the reform on the basis of unitary estimates.      

Understanding changes in Māori incomes and income inequality 1997–2003

This paper examines recent changes in weekly income levels and dispersion for Māori, New Zealand’s indigenous ethnic group. Changes in the Māori income distribution between 1997 and 2003 reflect rapid increases in economic growth and employment rate. A reduced proportion of people had zero or benefit-level incomes and a higher proportion had high incomes. Income inequality declined for working-aged Māori and was stable for employed Māori. The average income gap between Māori and Europeans declined. The increased Māori employment rate during this period was the single most important driver of changes in the Māori income distribution.

Family structure and child outcomes in the USA and Sweden

Previous research shows that living in a non-intact family is associated with educational disadvantages. This paper compares the relationships between childhood family structure, schooling, and earnings in Sweden and the USA. This comparison is interesting because both family structure and public policies differ significantly. We find a negative relationship between living in a non-intact family and child outcomes, and the estimates are remarkably similar in both countries. After using sibling-difference models, the correlation with family structure is no longer significant. These results cast doubt on the causal interpretation of the negative relationship between non-intact family structures and child outcomes.

The EU‐Turkey‐'deal': Legal Challenges and Pitfalls

The EU‐Turkey “deal”, based on the Joint Action Plan (JAP) between the European Union (EU) and Turkey, raises fundamental questions on the range of European asylum law as well as on the scope of the safe third country concept, which has turned out to serve as a political master key to “solve” the problems of the so‐called “refugee crisis” in Europe. This article discusses the legal possibilities of the application of the concept as well as its limitations regarding the human rights orientation of European and international law, focusing on the evolvement and legal implementation of the “Merkel Plan”. The legal analysis also focusses on recent ideas to make new “deals” with third states such as Libya. It concludes with a critical but differentiated(?) acclaim of the controversial externalizing policy approach.     

Large-scale commonness is the best predictor of bird species presence in European cities

Training Bodies,Building Status: Negotiating Gender and Age Differences in the U.S. Fitness Industry

What role does the body play in facilitating interaction across status differences? Whereas previous scholarly work has focused on “roles” and “specialized knowledge,” I investigate how bodies, appearances, and physical abilities are also consequential in these exchanges through the concept of “bodily capital.” Coined by Bourdieu, bodily capital provides a way to understand why individuals invest time, energy, and resources into their bodies, and what they expect to receive in return. As a concept, bodily capital is necessarily broad as it encompasses a variety of forms, including athletic prowess, attractiveness, physique, muscle tone/strength, agility, and other modes of embodiment. Because the body is integral to a variety of status distinction-making processes, individuals invest in and exchange bodily capital to increase their relative status in specific fields. Drawing on interviews with 26 personal trainers and 25 clients, as well as more than one year of participant observation, I find that trainers and clients use bodily capital to negotiate gender and age differences, either by re-arranging interactional power dynamics or resisting stereotypes. The type of bodily capital that allows for such negotiations to take place, however, is the hegemonic thin-toned ideal—a classed and largely raced form of bodily capital that has purchase in the U.S. fitness industry. Although individuals in the study were able to use this form of capital to enable successful cross-status interactions, doing so reified the dominance of middle-class, white bodily aesthetics. Thus, while bodily capital may challenge some status hierarchies, it reinforces others.     

Individuals and Communities: the Importance of Neighbors Volunteering

In this analysis, I examine the effects of community-level volunteering on an individual’s choices regarding time – whether to work and whether to volunteer. In order to better explain the decision to volunteer, a classic pure public goods structure is contrasted with a less restrictive impure public goods model that admits other possible private motivations. The results of this study undermine the neoclassical notion that volunteering can be understood solely as a pure public good that is provided less when others are seen to be contributing. In fact, individuals are found to be more, not less, likely to volunteer when others in their communities do so. An innovative instrumental variables strategy is used to account for reflection bias and the possible endogeneity caused by selective sorting of individuals into neighborhoods, which allows for a causal interpretation of these results. Employment regressions provide preliminary evidence that average volunteering relates, to some extent, with the decision of whether to participate in the labor force. Variations in the effect of average volunteering across age and gender are also explored. The present work is unique by virtue of its use of a large and representative dataset, along with rigorous statistical testing. I use United States Census 2000 Summary File 3 and Current Population Survey (CPS) 2004–2007 September Supplement file data and control for various individual and community-level characteristics.     

Winning a Battle but Losing the War? Third Sector and Social Policy in Latin America: The Case of Uruguay

This paper analyzes some aspects of the third sector’s involvement process in the provision of public social services. Using evidence garnered in previous research based on in-depth interviews, I offer elements toward an assessment of the consequences this process has produced not only in terms of the gains and losses it has produced for social policy, but also for the very identity and constitutive characteristics of the third sector. The evidence hereby compiled strengthens skepticism toward the hypothesis that sees a transformative potential in the role of the third sector in social policy in Latin America. This skepticism arises from issues detected by involved actors themselves and that are linked to the weakness of the sector as a whole.
