Der Ebenenwechsel und seine Folgen Eine Gruppe experimentiert

Today, professionality is no longer safeguarded only by a specific professional membership. Particularly in the field of supervision, even organized supervisors have problems with quality safeguarding. For this reason the authors insist on a continuous reflection and development of concepts, and they report on their activities relating to this demand. The shift of level is a method of group dynamics based on the concept ”shift of perspectives“ in phenomenology.     

What is Loss Aversion?

A behavioral definition of loss aversion is proposed and its implications for original and cumulative prospect theory are analyzed. Original prospect theory is in agreement with the new loss aversion condition, and there utility is capturing all effects of loss aversion. In cumulative prospect theory loss aversion is captured by both the weighting functions and the utility function. Further, some restrictions apply for the weighting functions involved in the latter model.We are indebted to Michèle Cohen and Peter Wakker for helpful comments. The suggestions of an anonymous referee have improved the presentation of the paper.

The Development of Students' Mathematics Self‐Concept in Relation to Gender: Different Countries,Different Trajectories?

Gender differences in the development of children's and adolescents' academic self‐perceptions have received increasing attention in recent years. This study extends previous research by examining the development of mathematics self‐concept across grades 7–12 in three cultural settings: Australia (Sydney; N=1,333), the United States (Michigan; N=2,443), and Germany (four federal states; N=4,688). Results of latent growth curve models document very similar patterns of self‐concept development in males and females in the three settings. First, gender differences in favor of boys were observed at the beginning of the observation period (grade 7). Second, gender was not significantly related to self‐concept change in either group, meaning that initial differences persisted across time. Third, the results provided no evidence that the form of the longitudinal change trajectories for mathematics self‐concept differed across the cultural settings. This pattern of results is inconsistent with explanatory models that predict converging or diverging gender differences in mathematics self‐concept. Furthermore, the results indicate that self‐concept development may be highly similar across western cultural settings.     

Insurance demand and social comparison: An experimental analysis

This paper analyzes whether social comparison can explain the low take-up of disaster insurance usually reported in field studies. We argue that risks in the case of disasters are highly correlated between subjects whereas risks for which high insurance take-up can be observed (e.g. extended warranties or cell phone insurance) are typically idiosyncratic. We set up a simple model with social reference points and show that in the presence of inequality aversion social comparison makes insurance indeed less attractive if risks are correlated. In addition we conducted a simple experiment which confirms these theoretical results. The average willingness to pay for insurance is significantly higher for idiosyncratic than for correlated risks.     

Testing transitivity in choice under risk

Recently proposed models of risky choice imply systematic violations of transitivity of preference. This study explored whether people show the predicted intransitivity of the two models proposed to account for the certainty effect in Allais paradoxes. In order to distinguish “true” violations from those produced by “error,” a model was fit in which each choice can have a different error rate and each person can have a different pattern of preferences that need not be transitive. Error rate for a choice is estimated from preference reversals between repeated presentations of the same choice. Results showed that few people repeated intransitive patterns. We can retain the hypothesis that all participants were transitive.     

The role of deliberate and experiential learning in developing capabilities: Insights from technology licensing

We discuss the interdependencies between deliberate and experiential learning in developing a dynamic technology licensing capability, which was termed ‘desorptive capacity’ in earlier conceptual work. We use new three-year lagged data from two surveys of 79 firms to examine the role of dedicated licensing employees and prior licensing experience in developing firms’ sensing, seizing, and transforming capacities in technology out-licensing. The findings emphasize capabilities’ multidimensionality and critical trade-offs due to interdependencies between deliberate and experiential learning in developing capabilities. Besides interdependencies with experiential learning, deliberate learning strengthens sensing and seizing capacity, but it negatively affects transforming capacity based on inertia.     

Ethnic Prejudice and Discrimination in Europe

This article provides an introduction to research on European prejudice and discrimination. First, we list the distinctive characteristics of a European perspective and provide a short sketch of European immigration and ethnic groups. Europe has become a multicultural community. Nevertheless, public opinion and the continent's politics often do not reflect this empirical fact. Prejudice and discrimination directed at immigrants are a widespread phenomena across Europe. Several cross-European surveys support this conclusion, although theoretically driven surveys on prejudice and discrimination in Europe remain rare. Cross-European research studies classical and modern theories of prejudice and discrimination and attempts to uncover the psychological mechanisms that explain individual readiness to exclude ethnic groups. A brief sketch of recent European research is presented. This issue offers both important cross-national perspectives as well as needed comparisons with the more studied case of racial prejudice and discrimination in the United States.
