The churches today are called to confess anew their faith, and to repent for the times when Christians have remained silent in the face of injustice or threats to peace. The biblical vision of peace with justice for all, of wholeness, of unity for all God's people is not one of several options for the followers of Christ. It is an imperative in our time.

We introduce the fundamental tenets of Bayesian inference, which derive from two basic laws of probability theory. We cover the interpretation of probabilities, discrete and continuous versions of Bayes’ rule, parameter estimation, and model comparison. Using seven worked examples, we illustrate these principles and set up some of the technical background for the rest of this special issue of Psychonomic Bulletin & Review. Supplemental material is available via https://osf.io/wskex/. 相似文献

Sensory responsiveness and the effects of equal subjective rewards on tactile learning and memory of honeybees 总被引:9,自引:0,他引:9 下载免费PDF全文

In tactile learning, sucrose is the unconditioned stimulus and reward, which is usually applied to the antenna to elicit proboscis extension and which the bee can drink when it is subsequently applied to the extended proboscis. The conditioned stimulus is a tactile object that the bee can scan with its antennae. In this paper we describe the quantitative relationships between gustatory antennal stimulation, gustatory proboscis stimulation, and tactile learning and memory. Bees are 10-fold more responsive to sucrose solutions when they are applied to the antenna compared to proboscis stimulation. During tactile conditioning, the sucrose solution applied to the proboscis determines the level of acquisition, whereas antennal input is of minor importance. Bees differing in their gustatory responsiveness measured at the antenna differ strongly in their tactile acquisition and memory. We demonstrate how these differences in tactile acquisition and memory can be greatly reduced by calculating equal subjective rewards, based on individual gustatory responsiveness. 相似文献

This study investigates the internal structure and construct validity of Complex Problem Solving (CPS), which is measured by a Multiple-Item-Approach. It is tested, if (a) three facets of CPS - rule identification (adequateness of strategies), rule knowledge (generated knowledge) and rule application (ability to control a system) - can be empirically distinguished, how (b) reasoning is related to these CPS-facets and if (c) CPS shows incremental validity in predicting school grade point average (GPA) beyond reasoning. N = 222 university students completed MicroDYN, a computer-based CPS test and Ravens Advanced Progressive Matrices. Analysis including structural equation models showed that a 2-dimensionsal model of CPS including rule knowledge and rule application fitted the data best. Furthermore, reasoning predicted performance in rule application only indirectly through its influence on rule knowledge indicating that learning during system exploration is a prerequisite for controlling a system successfully. Finally, CPS explained variance in GPA even beyond reasoning, showing incremental validity of CPS. Thus, CPS measures important aspects of academic performance not assessed by reasoning and should be considered when predicting real life criteria such as GPA. 相似文献

Because previous studies examining correlations between perfectionism and social desirability produced inconclusive findings, this study used an experimental approach examining the perceived social desirability of perfectionism. 117 university students were randomly assigned to three conditions (fake-good, standard, and fake-bad instructions) and then completed measures of self-oriented, other-oriented, and socially prescribed perfectionism. Results showed that all three forms of perfectionism were perceived as socially desirable. Self-oriented perfectionism showed a strong linear trend across the conditions: Students reported significantly higher self-oriented perfectionism in the fake-good condition, and significantly lower self-oriented perfectionism in the fake-bad condition compared to standard instructions. Other-oriented perfectionism showed the same linear trend, albeit weaker, and only fake-good and fake-bad conditions differed significantly. Socially prescribed perfectionism too showed a significant linear trend: Students reported higher levels in the fake-good condition compared to standard instructions and fake-bad condition, with no significant difference between the latter conditions. The findings indicate that, in educational settings, students perceive perfectionism—including maladaptive forms such as socially prescribed perfectionism—as socially desirable. 相似文献

Communication research highlights deficiencies in the media’s representation of migrants. The study at hand analyzes these deficiencies from the perspective of the migrants concerned: How do they perceive their representation in the media, especially on television? And how do they assess the perceived situation with regard to immigrant integration? This topic has been examined in a qualitative pilot study based on six group discussions amongst migrants and Swiss citizens with an immigration background in the German-, French-, and Italian-speaking parts of Switzerland. The results show a high discrepancy between the desire for more presence and participation on the one hand, and the wish to stand in the spotlight less often, on the other hand. 相似文献

Recent evidence from choice response time experiments with variable foreperiods (FPs) has shown that temporal expectancy can be event specific. When a certain target appears particularly frequent after one certain FP, participants tend to expect that target after that FP. This typically results in best performance for that target when it appears after that FP. In the present study, we investigated how temporally precise event-specific temporal expectancy is, and in which range of FPs it can be found. Two target stimuli were asymmetrically distributed over two "peak-FPs" and were equally distributed over 13 additional FPs. Event-specific expectancies were found for peak-FP pairs of 500/1,100?ms and 300/500?ms. Furthermore, the event expectancies generalized to a wide range of nonpeak FPs surrounding the peak FPs. 相似文献
