Sozioökonomischer Status,Deprivation und die Affinität zur <Emphasis Type="Italic">AfD</Emphasis> – Eine Forschungsnotiz

Using three recent data sets (ALLBUS 2016, GLES 2016, ESS 2016), we show that the affinity for the AfD is a socially stratified phenomenon. Actors with minimal education and low income, the unemployed, workers, and actors who feel deprived in socioeconomic terms have a stronger tendency towards supporting the AfD than those actors with a higher socioeconomic status. This finding contrasts with previous research, which describes the rise of right-wing populism in Germany as the result of some kind of clash of idealistic cultures lacking any foundation in the economic basis of society.     

The Value of Environmental Information without Control of Subsequent Decisions

The standard value of information approach of decision analysis assumes that the individual or agency that collects the information is also in control of the subsequent decisions based on the information. We refer to this situation as the “value of information with control (VOI‐C).” This paradigm leads to powerful results, for example, that the value of information cannot be negative and that it is zero, when the information cannot change subsequent decisions. In many real world situations, however, the agency collecting the information is different from the one that makes the decision on the basis of that information. For example, an environmental research group may contemplate to fund a study that can affect an environmental policy decision that is made by a regulatory organization. In this two‐agency formulation, the information‐acquiring agency has to decide, whether an investment in research is worthwhile, while not being in control of the subsequent decision. We refer to this situation as “value of information without control (VOI‐NC).” In this article, we present a framework for the VOI‐NC and illustrate it with an example of a specific problem of determining the value of a research program on the health effects of power‐frequency electromagnetic fields. We first compare the VOI‐C approach with the VOI‐NC approach. We show that the VOI‐NC can be negative, but that with high‐quality research (low probabilities of errors of type I and II) it is positive. We also demonstrate, both in the example and in more general mathematical terms, that the VOI‐NC for environmental studies breaks down into a sum of the VOI‐NC due to the possible reduction of environmental impacts and the VOI‐NC due to the reduction of policy costs, with each component being positive for low environmental impacts and high‐quality research. Interesting results include that the environmental and cost components of the VOI‐NC move in opposite directions as a function of the probability of environmental impacts and that VOI‐NC can be positive, even though the probability of environmental impacts is zero or one.     

Leveraging global sources of knowledge for business model innovation

This article explores the concept of leveraging global knowledge for business model innovation, whereby knowledge is transferred across space and firm boundaries for the reconfiguration of an incumbent firm's business model. Considering the implications of an ever-increasing fragmentation of global value chains and the associated dispersion of global knowledge sources, we propose that supply chain partners at foreign locations can provide valuable knowledge that incumbents can leverage to change their business model. Integrating insights from global supply chain, business model, and organizational learning literature, we theorize and empirically test how different organizational capabilities enable firms to acquire knowledge from foreign partners, integrate external with internal knowledge, transform knowledge through experimentation, and finally apply global knowledge in the form of business model innovation. We conclude with suggestions for future research.     

Linking Maternal Warmth and Responsiveness to Children's Self‐regulation

The present study demonstrated that a more differentiated view of positive parenting practices is necessary in the study of children's acquisition of self‐regulation. Here, the unique contributions of maternal warmth and responsiveness to distress to children's self‐regulation were tested in a sample of 102 German mothers and their kindergarten children (51 girls and 51 boys). Behavior regulation and internalization of rules of conduct were examined as specific components of children's self‐regulation. As expected, maternal warmth was positively related to the child's behavior regulation. Responsiveness to distress was positively linked to the child's internalization of rules of conduct. No significant interactions between maternal parenting and either the child's gender or effortful control were found. The results are discussed with regard to the unique functions that different parenting practices have for children's self‐regulation.

Gewalt als Reaktion auf Anerkennungsdefizite?

Violence between adolescents is primarily a male phenomenon. For this reason, the analysis of violent behavior focuses on 4.213 male adolescents from three different backgrounds: adolescents of Turkish descent, late migrants from Russia and Poland (Aussiedler) and native Germans. They all are attending schools (10th grade) in Northrhine-Westfalia, Germany. The data have been provided by the Youth-Survey 2001 of the Institute for Interdisciplinary Research on Conflict and Violence (IKG). The theoretical framework is provided by the theory of disintegration developed at the IKG. In comparison to Germans, Turkish adolescents show a higher rate of violence. The bivariate effect of Turkish descent on violent behavior can in multivariate logistic regression analysis partly be explained by a lack of recognition at the institutional and at the socio-structural dimensions of integration: In comparison to Germans, Turkish adolescents experience more discrimination, both in their daily life and in their school career. Those German adolescents and late migrants who suffer from a comparable degree of discrimination show similar patterns of violent behavior. Lack of recognition at the socio-emotional dimension (i.e. the relationship with the parents) have a smaller effect on violent behavior. In sum, especially the accumulation of deficits at different dimensions of integration in Germany heightens the risk for violent action.     

Comparing Experimental Designs for Benchmark Dose Calculations for Continuous Endpoints

The BMD (benchmark dose) method that is used in risk assessment of chemical compounds was introduced by Crump (1984) and is based on dose-response modeling. To take uncertainty in the data and model fitting into account, the lower confidence bound of the BMD estimate (BMDL) is suggested to be used as a point of departure in health risk assessments. In this article, we study how to design optimum experiments for applying the BMD method for continuous data. We exemplify our approach by considering the class of Hill models. The main aim is to study whether an increased number of dose groups and at the same time a decreased number of animals in each dose group improves conditions for estimating the benchmark dose. Since Hill models are nonlinear, the optimum design depends on the values of the unknown parameters. That is why we consider Bayesian designs and assume that the parameter vector has a prior distribution. A natural design criterion is to minimize the expected variance of the BMD estimator. We present an example where we calculate the value of the design criterion for several designs and try to find out how the number of dose groups, the number of animals in the dose groups, and the choice of doses affects this value for different Hill curves. It follows from our calculations that to avoid the risk of unfavorable dose placements, it is good to use designs with more than four dose groups. We can also conclude that any additional information about the expected dose-response curve, e.g., information obtained from studies made in the past, should be taken into account when planning a study because it can improve the design.
