The role of ethnic origin and situational information in teachers’ reactions to social exclusion among students

Social Psychology of Education - The current study investigated pre- and in-service teachers' reactions to interethnic exclusion in Germany. Using hypothetical scenarios, we examined a sample...     

Therapy for couples after an affair: A randomized-controlled trial

To examine the efficacy of a couples treatment approach for promoting recovery from a recently disclosed affair, 89 couples that disclosed an affair by one of the partners in the past 6 months were randomly assigned to treatment (n = 46) or to a control group that waited about 3 months for treatment (n = 43). The couples completed self-report measures (Beck Depression Inventory, Impact of Event Scale-Revised, Partnership Questionnaire) at pre- and post-treatment. Since about half of the couples dropped out for various reasons (e.g., ongoing affair, separation), we used multiple imputations to handle the missing data problem. We analyzed the dyadic data with hierarchical linear modeling in a two-level model. Significant improvements on scores of anxiety corresponded with large effect sizes for both partners. Yet significant improvements on depression scores were only found for the unfaithful partner with moderate effect size. Results suggest that the treatment can improve individual complaints, but not relationship satisfaction in a sufficient amount for both partners. Hence, future research should address how this intervention could encourage couples to maintain therapy, and how they might achieve more and sustained improvement in relationship satisfaction.     

Junge ?Mehrfach- und Intensivt?ter“

Reoffending by young persons has led to the introduction of ??persistent offender programs?? in the police forces of most Federal states. In criminological research, too, multiple delinquencies are a phenomenon which receives a lot of attention. However, quite often there is still no connection between the criminological findings and the way these offenders are managed by the police. Therefore, it is the objective of this contribution to show the potential and the need for a closer interlinking of both areas. In this context, special emphasis is placed on the selection of persons to participate in programs for multiple and prolific offenders, in particular on the often used criterion of a negative prognosis on further delinquency. In principle, the inclusion of the findings of prognosis research promises a potential for optimization. However, police framework conditions need to be given special consideration in this connection. The necessity for interaction arises from the desire to use the limited resources of the police as efficiently as possible. On the other hand any police intervention influences the further course of the lives of young people so that the selection of the target group and the further police measures involve a great deal of responsibility.     

Computing Pareto‐optimal Predictor Composites for Complex Selection Decisions

A complex selection situation encompasses vacancies for several different positions and applicants that apply simultaneously for one or several of these positions. This article presents an analytic method for estimating the expected selection quality, as well as the adverse impact ratio of these complex selections, when the decisions are based on a single predictor composite score. In addition, the method is integrated within a broader decision‐making framework for designing complex selection decisions that show a Pareto‐optimal balance between the selection quality and diversity goals. Finally, the decision aid is used to demonstrate the importance of applying the appropriate selection format (either the simple or the complex format) when exploring the front of Pareto‐optimal outcomes of planned selections.     

Self-Report and Observer Ratings of Personality Functioning: A Study of the OPD System

Recent considerations around DSM–5 criteria of personality disorders (PDs) demand new concepts of assessing levels of personality functioning. Of special interest are multiperspective approaches accounting for clinicians’ as well as patients’ points of view. The study investigates observer-rated and self-assessed levels of personality functioning measured by the level of structural integration as defined by the Operationalized Psychodynamic Diagnosis System (OPD). Both perspectives were positively related. The combination of both measures was most efficient in discriminating among 3 diagnostic groups of varying degrees of personality dysfunction. Future studies should take into account expert ratings as well as self-report data.     

Different responses of two strains of chickens to different training procedures for magnetic directions

In previous conditioning experiments training domestic chickens to magnetic directions, a brown strain solved the task, whereas a white strain seemed unable to do so (Freire et al. Anim Cogn 11:547–552, 2008). To test whether this was possibly caused by loss of magnetic compass orientation in the white chickens, we analyzed the distribution of cryptochrome 1a, the candidate receptor molecule mediating magnetic compass information, in the retinae of Lohmann Browns and White Leghorns and found no difference between the two strains. Yet, subsequent training experiments replicated the former findings: Lohmann Browns used the magnetic field to find an imprinting stimulus hidden behind the screen in a specific magnetic direction, whereas White Leghorns did not solve the task. However, when we altered the training method by training also in a magnetic field with North shifted to geographic East and including a punishment for incorrect choices, the performance of White Leghorns improved to a significant preference for the expected directions. The Lohmann Browns, on the other hand, seemed frightened and chose randomly. Our results thus demonstrate the crucial role of the training method for conditioning to magnetic stimuli, with differences found even between strains of the same species.     

Abstract argumentation and explanation applied to scientific debates

Abstract argumentation has been shown to be a powerful tool within many fields such as artificial intelligence, logic and legal reasoning. In this paper we enhance Dung’s well-known abstract argumentation framework with explanatory capabilities. We show that an explanatory argumentation framework (EAF) obtained in this way is a useful tool for the modeling of scientific debates. On the one hand, EAFs allow for the representation of explanatory and justificatory arguments constituting rivaling scientific views. On the other hand, different procedures for selecting arguments, corresponding to different methodological and epistemic requirements of theory evaluation, can be formulated in view of our framework.
