Frühkindliche Essstörungen:Der Kampf ums Essen

H?ufigkeit, Risikofaktoren, Symptome - Wenn Babys und Kleinkinder die Nahrungsaufnahme boykottieren, sind die Eltern zurecht besorgt und suchen Hilfe beim Kinderarzt. Als Risikogruppe gelten insbesondere Frühgeborene. Weshalb gerade sie betroffen sind, wurde in einer Studie in Gie?en untersucht.     

The Impact of Corporate Social Responsibility Disclosure on Corporate Reputation: A Non-professional Stakeholder Perspective

This paper examines the impact of corporate social responsibility (CSR) disclosure on corporate reputation as perceived by non-professional stakeholders. Proponents of CSR disclosure argue that CSR disclosure can be considered as a tool for reputation management. We empirically investigate this claim using a reputation index which tracks the general public’s perceptions of corporate reputation over time. In our analysis, we focus on disclosure in stand-alone CSR reports and control for CSR performance. We find that, in contrast to the common belief, stand-alone CSR reports do not influence corporate reputation among non-professional stakeholders. However, we are able to document that stand-alone CSR reports influence corporate reputation among professional stakeholders. We also provide some evidence that transparent CSR disclosure on corporate websites can influence corporate reputation among non-professional stakeholders.     

Focus groups as a tool in the construction of questionnaires: the case of discriminatory attitudes

The aim of the present article is twofold First, it tests and demonstrates the supplementary use of focus groups to construct quantitatively oriented survey on anti-minority sentiment. Second, it clarifies two major theoretical concepts-prejudice versus perceived threat-in the research on discriminatory attitudes towards minority populations. More specifically, by using data from focus group discussions on foreign workers in Israel, the study examines the use of such groups for measurement of prejudice and perceived threat within the social and cultural context of Israeli society. The analysis of focus group discussions provides adapted questionnaire scales for measuring prejudice and perceived threat. The findings support the premise that prejudice and perceived threat are two distinct theoretical concepts.     

An experimental study of democracy breakdown,income and inequality

Many empirical studies investigate the relationships between economic development, inequality, and democracy survival; however, establishing causal links with naturally occurring cross-country data is problematic. We address this question in a laboratory experiment, where in democracy citizens can invest in profitable projects and vote on income taxation. In the alternative regime—autocracy—efficient investment levels and equitable redistribution are implemented exogenously, but there is a risk of resources being partially expropriated. Citizens can voluntarily switch from democracy to autocracy by a majority vote, which mimics recent historical examples, where voters voluntarily delegate political powers to an autocrat in exchange for a promise of high taxation and redistribution. We find that the likelihood of democracy breakdown increases with the degree of inequality but does not vary with productivity. The link between productivity and democracy survival depends critically on the degree of sophistication of the median voter.     

Does conglomeration really reduce credit risk?

I quantify the effects of conglomeration on credit risk by first computing theoretical default probabilities for conglomerates and their hypothetical stand‐alone counterparts and then mapping them into physical probabilities using a comprehensive database of corporate failures. Comparing the credit risk of conglomerates with that of hypothetical stand‐alone firms, I report significant reductions in the annual probability of default for small firms. My results support the proposition that managers can have a strong incentive to engage in conglomeration, even if it reduces shareholder value and show for which firms this is the case.     

A play-the-winner-type urn design with reduced variability

We propose a new adaptive allocation rule, the drop-the-loser, that randomizes subjects in the course of a trial comparing treatments with dichotomous outcomes. The rule tends to assign more patients to better treatments with the same limiting proportion as the randomized play-the-winner rule. The new design has significantly less variable allocation proportion than the randomized play-the-winner rule. Decrease in variability translates into a gain in statistical power. For some values of success probabilities the drop-the-loser rule has a double advantage over conventional equal allocation in that it has better power and assigns more subjects to the better treatment.

Self‐employment among women: Do children matter more than we previously thought?

This paper presents an estimation approach that addresses the problems of sample selection and endogeneity of fertility decisions when estimating the effect of young children on women's self‐employment. Using data from the National Longitudinal Survey of Youth 1979, 1982–2006, we find that ignoring self‐selection and endogeneity leads to underestimating the effect of young children. Once both sources of biases are accounted for, the estimated effect of young children roughly triples when compared to uncorrected results. This finding is robust to several changes in the specification and to the use of a different dataset.
