Optimization of Social Structure in Business Networks by Grid-Technique and Polyhedral Analysis

This article deals with the definition and analysis of the social, communicative, and cognitive abilities of managers acting in network contexts. We can tackle the complex relationship of role demands and role adoption by applying grid-technique and polyhedral analysis. We can gather data on context-specific personal constructs with the help of the grid technique. Using these data, polyhedral analysis shows how defined persons are integrated into the relation structures within a network. Beyond this, we show if and how relevant criteria such as holes, connectivity, and eccentricity can be employed for analyzing problems stemming from personnel management. Based upon the applied methods, it is possible to provide information about the relevant structures within networks used in personnel selection and competency development. Decision makers have the task to select among the measures of personnel management. Within the relevant context, these measures should be suited to ensure the stability and efficiency of the network.     

Privileged, Typical, or not even that? – Our Place in the World According to the Copernican and the Cosmological Principles

Summary  If we are to constrain our place in the world, two principles are often appealed to in science. According to the Copernican Principle, we do not occupy a privileged position within the Universe. The Cosmological Principle, on the other hand, says that our observations would roughly be the same, if we were located at any other place in the Universe. In our paper we analyze these principles from a logical and philosophical point of view. We show how they are related, how they can be supported and what use is made of them. Our main results are: 1. There is a logical gap between both principles insofar as the Cosmological Principle is significantly stronger than the Copernican Principle. 2. A step that is often taken for establishing the Cosmological Principle on the base of the Copernican Principle and observations is not incontestable as it stands, but can be supplemented with a different argument. 3. The Cosmological Principle might be crucial for cosmology to the extent it is not supported by empirical evidence.     

Psychological effects of the Euro—experimental research on the perception of salaries and price estimations

In five studies we show that the introduction of the Euro influences price estimations and the perception of salaries among people in Germany. People confronted with wages given in Euros compared to the German Mark (DM) showed a reduced willingness to face long distances to get to work when accepting a job offer. When asked to price various consumer goods appropriately, they estimated higher prices if they used the ‘Euro’ currency compared to price estimations made in DM. This phenomenon only occurred with regard to the Euro, but not in comparison with other currencies (cf. the British Pound and Austrian Schilling). The differing price estimations between the Euro and the German Mark were not influenced by participants' attitude towards the Euro. Moreover, it turned out that they depended on how the judgement context was framed. Only if participants expected to make price estimations for shops in their home country, Germany, did the familiar nominal DM figures serve as an anchor heightening the estimated prices in Euro. The same effect disappeared if participants were instructed to make their price estimations for shops in a foreign country (Ireland). Copyright © 2002 John Wiley & Sons, Ltd.     

Negative Intergroup Contact and Radical Right‐Wing Voting: The Moderating Roles of Personal and Collective Self‐Efficacy

This study examines whether negative contact with immigrants promotes voting for radical right‐wing parties, to what extent this relationship can be explained by feelings of outgroup threat, and whether this relationship depends on perceived personal and collective self‐efficacy. Hypotheses were tested among 630 native Dutch respondents, mainly living in multicultural neighborhoods. The results show that negative contact with immigrants is associated with feelings of personal (egocentric) and group (sociotropic) threat, and both these feelings, in turn, are associated with radical right‐wing voting. However, negative intergroup contact is less strongly related to egocentric threat when individuals feel able to personally address negative situations with other people (personal self‐efficacy). Furthermore, the findings suggest that negative intergroup contact is less strongly related to sociotropic threat when individuals believe that people in their neighborhood are able to collectively address some negative situations (collective self‐efficacy).     

Positive mental health,positive affect and suicide ideation

Background/ObjectivePositive mental health (PMH) has been shown to confer resilience against suicide ideation. However, the mechanisms underlying the positive effect of PMH on suicide ideation/behavior are largely unknown. The current study aimed to determine whether positive affect mediates the association between PMH and suicide ideation.MethodA total of 150 adult outpatients (65.3%; female; age: M(SD)=37.79(13.50), range:18–77) completed measures on PMH, positive and negative affect, as well as suicide ideation. Data were collected using self-report questionnaires. Linear hierarchical regression analysis was used to analyze the data. Positive affect was considered to mediate the association between positive mental health and suicide ideation.ResultsWhile positive affect fully mediated the significant negative association between PMH and suicide ideation, negative affect did not reveal to be a significant mediator of this relationship.ConclusionsThe protective influence of PMH against suicide ideation is due to heightened positive affect: If positive mental health translates into positive affect, then suicide ideation becomes less likely.     

Self-regulation and selective exposure: the impact of depleted self-regulation resources on confirmatory information processing

In the present research, the authors investigated the impact of self-regulation resources on confirmatory information processing, that is, the tendency of individuals to systematically prefer standpoint-consistent information to standpoint-inconsistent information in information evaluation and search. In 4 studies with political and economic decision-making scenarios, it was consistently found that individuals with depleted self-regulation resources exhibited a stronger tendency for confirmatory information processing than did individuals with nondepleted self-regulation resources. Alternative explanations based on processes of ego threat, cognitive load, and mood were ruled out. Mediational analyses suggested that individuals with depleted self-regulation resources experienced increased levels of commitment to their own standpoint, which resulted in increased confirmatory information processing. In sum, the impact of ego depletion on confirmatory information search seems to be more motivational than cognitive in nature.     

What moderates implicit—explicit consistency?

Implicit and explicit indicators of attitudes or personality traits are positively, and variably, related. This review places the question of implicit ‐ explicit consistency into the tradition of attitude/trait ‐ behaviour consistency (e.g., Wicker, 1969). Drawing on dual-process models, such as the recent distinction between associative and propositional representations (Strack & Deutsch, 2004), we identify a working model of implicit ‐ explicit consistency that organises the empirical evidence on implicit ‐ explicit moderation into five factors: translation between implicit and explicit representations (e.g., representational strength, awareness), additional information integration for explicit representations (e.g., need for cognition), properties of explicit assessment (e.g., social desirability concerns), properties of implicit assessment (e.g., situational malleability), and research design factors (e.g., sampling bias, measurement correspondence).     

The Deductive-Nomological Account of Metaphysical Explanation

The paper explores a deductive-nomological account of metaphysical explanation: some truths metaphysically explain, or ground, another truth just in case the laws of metaphysics determine the latter truth on the basis of the former. I develop and motivate a specific conception of metaphysical laws, on which they are general rules that regulate the existence and features of derivative entities. I propose an analysis of the notion of ‘determination via the laws’, based on a restricted form of logical entailment. I argue that the DN-account of ground can be defended against the well-known objections to the DN-approach to scientific explanation. The goal of the paper is to show that the DN-account of metaphysical explanation is a well-motivated and defensible theory.     

Playing prosocial video games increases empathy and decreases schadenfreude

Past research provided abundant evidence that exposure to violent video games increases aggressive tendencies and decreases prosocial tendencies. In contrast, research on the effects of exposure to prosocial video games has been relatively sparse. The present research found support for the hypothesis that exposure to prosocial video games is positively related to prosocial affect and negatively related to antisocial affect. More specifically, two studies revealed that playing a prosocial (relative to a neutral) video game increased interpersonal empathy and decreased reported pleasure at another's misfortune (i.e., schadenfreude). These results lend further credence to the predictive validity of the General Learning Model (Buckley & Anderson, 2006) for the effects of media exposure on social tendencies.
