That’s not my place: The interacting effects of faultlines,subgroup size,and social competence on social loafing behaviour in work groups

Taking a social relations approach to team diversity, we propose that faultlines—hypothetical dividing lines that split a team into relatively homogeneous subgroups—impact the team members’ propensity to exhibit social loafing behaviour. We further propose that this individual-level reaction to the faultline structure of the team can differ among team members, depending on the size of their subgroup and on their individual social competence. We tested the assumptions with a sample of real teams working on an intellective task during which social loafing behaviour was video-coded. In partial support of the hypotheses, generalized mixed models revealed that social loafing behaviour was most common for team members who were part of a team with strong faultlines, who belonged to the larger subgroup in their team, and who exhibited low levels of social competence. The results therefore highlight the benefits of taking a multilevel approach to the effects of faultlines.     

Socio-cognitive processes associated with paruresis and parcopresis symptoms: A proposed bivalent model

Current Psychology - Paruresis has been recognized as a subtype of Social Anxiety Disorder (SAD). A well-established model of SAD is the extended bivalent fear of evaluation model (extended BFOE)...

The sales manager as a unit of analysis: a review and directions for future research

This article analyzes empirical research in which the sales manager is the unit of analysis to determine what knowledge has been generated by sales scholars about sales managers and sales management practice. It examines what we have learned from sales managers about their jobs and themselves with particular emphasis on the managerial relevance of the work. While the sales literature is vast and despite the importance of sales managers being widely recognized and accepted, an extensive search of the sales literature identified only 163 articles in which the sales manager was the focus of empirical research about what they do. To help better understand what has been discovered, these articles are examined and categorized according to the main focus of each article's research. The results show that with respect to sales managers, our knowledge is limited and substantial opportunities exist for additional research to expand our understanding of the nature, roles, and impact of sales managers as well as providing usable advice for the practice of sales management.     

Motivational mindsets versus reasons for action: implications for the dimensionality debate in self-determination theory

Motivation and Emotion - Within self-determination theory, motivation has been treated as a unidimensional (autonomy continuum) and multidimensional (types of motivation) construct. We propose that...

A General Family of Preferential Belief Removal Operators

Most belief change operators in the AGM tradition assume an underlying plausibility ordering over the possible worlds which is transitive and complete. A unifying structure for these operators, based on supplementing the plausibility ordering with a second, guiding, relation over the worlds was presented in Booth et al. (Artif Intell 174:1339–1368, 2010). However it is not always reasonable to assume completeness of the underlying ordering. In this paper we generalise the structure of Booth et al. (Artif Intell 174:1339–1368, 2010) to allow incomparabilities between worlds. We axiomatise the resulting class of belief removal functions, and show that it includes an important family of removal functions based on finite prioritised belief bases.     

The role of sincere amends and perceived partner responsiveness in forgiveness

In a sample of 188 people currently in a romantic relationship, the authors examined the extent to which perceiving a partner as responsive and sincere in making amends relates to participants' forgiveness of a partner after a real‐life hurtful event. Specifically, it was predicted that sincere amends would be associated with greater forgiveness because it conveys that one's partner has understood and validated one's experience of the hurtful event. Results supported this mediational model. Further, exploratory analyses suggested that this meditational model is moderated by event severity and relationship satisfaction. Discussion focuses on understanding how this work might help to inform the dynamic process of forgiveness in couples.     

Dynamic properties of an ultrafine-grained Mg–Zn–Zr alloy

The effect of ultrafine-grained structure formation in Mg–Zn–Zr alloy ZK60 on its mechanical response was investigated at strain rates ranging from quasi-static to dynamic regimes. The study demonstrated that the strength characteristics of the material rise significantly with increasing strain rate, while its ductility is reduced. These effects are particularly pronounced in the dynamic loading regime, at strain rates in the (1?5)?×?10²?s^?1 range. In the ultrafine-grained alloy ZK60, the energy absorption per unit volume, W, is enhanced by grain refinement by a factor as high as eight for the highest strain rate of 5?×?10²?s^?1 investigated. The analysis is focused on the microstructure features that bring about the observed improvement of the tensile characteristics, as well as the deformation and fracture modes prevalent at different strain rates. The results obtained contribute to the exploration and understanding of dynamic behaviour of magnesium alloys.     

Temporal characteristics of the surprise reaction induced by schema-discrepant visual and auditory events

Abstract

Two experiments investigated the effects of a schema-discrepant event on the surprise reaction. Schema-discrepancy concerned a physical feature of irrelevant distractor words that were presented while the subjects performed a choice reaction time task. The stimulus onset asynchrony (SOA) between the distractors and the task-relevant stimuli was manipulated in both experiments. The occurrence of the schema-discrepant event led to subjective feelings of surprise and enhanced recall of the stimulus material. In Experiment 1, the presentation of a schema-discrepant auditory event resulted in a pronounced increase of reaction time (RT) with a 0.2sec SOA but not with a 1.5sec SOA. In Experiment 2, the effects of both fixed and variable SOAs of four different lengths (simultaneous onset, 0.5sec, 1sec, or 2sec SOA) were investigated within a visual task context. The increase of RT was found to be most pronounced with SOAs of 0.5sec and lsec respectively, and more pronounced with variable than with fixed SOAs, especially with a simultaneous onset. These results provide information about the temporal characteristics of the inhibitory component of the surprise reaction, and suggest that the inhibitory effects of surprise depend considerably on the subjects' state of preparation for the experimental task.
