Self-concept clarity and religious orientations: prediction of purpose in life and self-esteem

The present study concerns the relationship between self-concept clarity, religiosity, and well-being, as well as the mediating influence of religiosity on the relationship between self-concept clarity and sense of meaning in life and self-esteem. Self-concept clarity was found to be a significant predictor of sense of meaning in life and self-esteem; intrinsic religious orientation was found to be a predictor of sense of meaning in life, while the quest religious orientation was a predictor for self-esteem. The cross-products of self-concept clarity and intrinsic religious orientation were found to be related to the sense of purpose in life, which would point to religiosity being a mediator of the relationship between self-concept clarity and sense of purpose in life. The cross-products of self-concept clarity and quest religious orientation were found to be a predictor of self-esteem, which indicates a mediating effect of this religious orientation in the relationship of self-concept clarity and self-esteem.     

Collective regret versus collective guilt: Different emotional reactions to historical atrocities

A distinction between guilt and regret in reactions to in‐group atrocities is proposed. Four studies (total N = 1249) support the notion that guilt and regret are distinct emotional reactions. Whereas guilt is a self‐focused, aversive emotional reaction following from appraisals of responsibility and associated with the intention to make amends, regret follows from an empathic victim perspective, is less aversive, and is more strongly associated with positive attitudes towards the victim groups and the intention to engage in intergroup contact. These findings suggest that less aversive emotions like regret are more likely to improve intergroup attitudes after a common history of conflict, but the aversive experience of guilt might be more potent in motivating reparations.

Mechanisms of contextual control when contexts are informative to solve the task

An experiment was conducted using a human instrumental learning task with the goal of evaluating the mechanisms underlying the deleterious effect of context-switching on responding to an unambiguous stimulus when contexts are informative to solve the task. Participants were trained in a context-based reversal discrimination in which two discriminative stimuli (X and Y) interchange their meaning across contexts A and B. In context A, discriminative stimulus Z consistently announced that the relationship between a specific instrumental response (RI) and a specific outcome (O1) was in effect. Performance in the presence of stimulus Z was equally deteriorated when the test was conducted outside the training context, regardless of whether the test context was familiar (context B) or new (context C). This result is consistent with the idea that participants code all the information presented in an informative context as context-specific with the context playing a role akin to an occasion setter.     

Microstructure and superconductivity of bulk BPSCCO/LPMO composite

Bulk superconducting (SC) ceramics containing BPSCCO and LPMO (Lanthanum/Lead – manganite phase) have been produced. The initial components were prepared by a low-temperature Pechini method. The submicron powders in weight ratio 90/10 Bi_1.6Pb_0.4Sr₂Ca₂Cu₃O_z/La_0.6Pb_0.4MnO₃ (nominal composition) were heat treated at 840°C. The duration of the heat treatment effect (60 and 100?h) of the composite on the transformation of the microstructure was studied. The obtained composites were analyzed by scanning electron microscopy (SEM) and by the method of energy-dispersive X-ray spectroscopy (EDX). They contain several phases. It was established that the SC 2212 phase is predominate in the composite. The phase La_0.6Pb_0.4MnO₃ transforms in solid solution with preliminary composition La_0.5(Sr?+?Ca)_0.5Mn_{1? z} Cu _z O₃, which after full replacement of the La and Mn ions leads to the appearance of phases with nominal composition Sr_{1? x} Ca _x CuO _y . AC and DC magnetization measurements were used to study the SC and magnetic properties of the samples. Both samples are SC with critical temperatures 75 and 77?K, respectively. It was concluded that the SC and magnetic phases stably coexist in the composite sintered at 60?h heat treatment at 840°C.
