INCOMPLETE INFORMATION STRENGTHENS THE EFFECTIVENESS OF SOCIAL APPROVAL

We present a theoretical model of a public good game in which the expression of social approval induces pro‐social behavior. Using a laboratory experiment with earned heterogeneous endowments, we test our model. The main hypothesis is that the expression of social approval increases cooperative behavior even if reputation building is impossible. We vary the information available and investigate how this affects the expression of social approval and individual contributions. The expression of social approval significantly increases contributions. However, the increase is smaller if additional information is provided, suggesting that social approval is more effective if subjects receive a noisy signal about others' contributions.

Sustainability—a theoretical idea or a practical recipe?

In this paper, the notion of sustainability as a general regulative idea is distinguished from sustainable development as a more concrete concept leading to practical actions. After that, different economic meanings of sustainable development are discussed, and a concept of critical sustainability is proposed especially with respect to the problem of climate change. Maintaining critical crash barriers and bottlenecks presupposes, however, demanding, continuous improvements in energy efficiency. After discussing problems of decision theory in cases of uncertainty, which is constitutive for climate change, the links between intragenerational and intergenerational justice are analyzed, and by using Barry's notion of justice and Goodin's concept of vulnerability, two possible positions of the general idea of fairness inherent in sustainable development are presented. We conclude by shortly sketching the notion of sufficiency as an additional supplementary sustainability strategy in cases where efficiency improvements based on innovation are less than sufficient for securing the (energetic) fundaments of economic activity and human life.     

Testing noninferiority in three‐armed clinical trials based on likelihood ratio statistics

Clinical noninferiority trials with at least three groups have received much attention recently, perhaps due to the fact that regulatory agencies often require that a placebo group be evaluated along with a new experimental drug and an active control. The authors discuss likelihood ratio tests for binary endpoints and various noninferiority hypotheses. They find that, depending on the particular hypothesis, the test reduces asymptotically either to the intersection‐union test or to a test which follows asymptotically a mixture of generalized chi‐squared distributions. They investigate the performance of this asymptotic test and provide an exact modification. They show that this test considerably outperforms multiple testing methods such as the Bonferroni adjustment with respect to power. They illustrate their methods with a cancer study to compare antiemetic agents. Finally, they discuss the extension of the results to other settings, such as Gaussian endpoints.

Social Entrepreneurship: An exploratory citation analysis

Research on Social Entrepreneurship became a growing field of interest during the past decades. However, as the heterogeneity of investigated topics is rather large the purpose of this contribution is to provide an overview of the current state of research on Social Entrepreneurship. In doing so previous research is structured to identify major contributions and thereby key discussion lines within this field. Based on a bibliometric citation analysis of 129 core papers and 5,228 cited references, five topic clusters are identified within the field of Social Entrepreneurship: 1) Definitions and conceptual approaches, 2) Impetus, 3) Personality, 4) Impact and performance, and 5) Future research agenda. By reflecting the literature of each discussion line, a framework for the advancement of Social Entrepreneurship research is provided.     

The scars of youth: Effects of early‐career unemployment on future unemployment experience

Does early‐career unemployment cause future unemployment? The authors approach this question using German administrative matched employer–employee data that track almost 700,000 individuals over 24 years. Instrumenting early‐career unemployment with firm‐specific labour demand shocks, they find significant and long‐lasting “scarring effects”. In the mean, each additional day of unemployment during the first eight years on the labour market increases unemployment in the following 16 years by half a day. However, quantile regressions show that the scarring effects are much stronger for individuals who already suffer from lengthy and repeated spells of unemployment.     

The Therapeutic Misconception: A Threat to Valid Parental Consent for Pediatric Neuroimaging Research

Neuroimaging research has brought major advances to child health and well-being. However, because of the vulnerabilities associated with neurological and developmental conditions, the parental need for hope, and the expectation of parents that new medical advances can benefit their child, pediatric neuroimaging research presents significant challenges to the general problem of consent in the context of research involving children. A particular challenge in this domain is created by the presence of therapeutic misconception on the part of parents and other key research stakeholders. This article reviews the concept of therapeutic misconception and its role in pediatric neuroimaging research. It argues that this misconception can compromise consent given by parents for the involvement of their children in research as healthy controls or as persons with neurological and developmental conditions. The article further contends that therapeutic misconception can undermine the research ethics review process for proposed and ongoing neuroimaging studies. Against this backdrop, the article concludes with recommendations for mitigating the effects of therapeutic misconception in pediatric neuroimaging research.     

Zwischen Säkularisierung und religiöser Reorganisation – Eine Analyse der Religiosität türkischer und polnischer Neuzuwanderer in Deutschland

This paper addresses the role of religion in the process of immigrant integration in Germany. Based on novel data (SCIP 2010/11) from a survey among new Polish and Turkish migrants, it particularly focuses on the impact of the migratory event upon religious participation and private religious practice as well as on early trends of changing religiosity in the receiving context. The study confirms, first of all, that both groups of newcomers experience a decrease in religious practices after the migratory event. This decrease is more pronounced among Muslim Turks than among Catholic Poles and more pertinent for worship attendance than for prayer, thus attesting to the relevance of religious opportunity structure. Secondly, it can be shown that among new Polish immigrants, religious decrease is more pronounced among individuals with stronger social ties to the secular German mainstream, while this is not the case for Turks. For them, thirdly, it seems that religious practices are being re-captured after the rather disruptive first couple of months in what may a called a process of religious re-organizations. These group-comparative findings attest to limits of classical assimilation theory and to the relevance of symbolic boundary dynamics. Overall, they underline that publicly visible religious diversity will remain a permanent feature of modern immigrant societies.
