This study addresses the following: (1) does a team leader change along with the quality of the team’s human capital affect post-change team performance?; (2) is functional leadership of the team’s human capital a driver of post-change team performance?; and (3) should interim vs. permanent leaders manage the team’s human capital differently? We analyzed archival data from Major League Baseball teams who had undergone an in-season manager change (N = 129). Team performance improved after a leader change, and the quality of the team’s strategic and non-strategic core human capital were positively related to post-change performance. New leaders who engaged in more active functional leadership of the strategic core human capital enhanced the positive effects of human capital quality. Additionally, active functional leadership enhanced the positive effects of strategic core human capital for interim replacement leaders, but not for permanent replacement leaders. This study extends theory and practice on the importance of functional team leadership and human capital following a leader transition. As such, our results provide actionable knowledge for organizations and managers who are part of leadership transitions. This empirical study leverages a unique sample to provide insights into the implications of team leader transitions. The results of this study shed light on the impact that leader transitions which involve “interim” and “permanent” replacements may have on post-transition team performance and how these different types of leaders should leverage the inherent human capital that exists within the team.  相似文献

The literature contains numerous reports on motivation in blood donors, although none of these are specific to blood donation in Italy and almost all of them focus on altruism and the desire to help others. Altruism is important, but a comprehensive analysis of donor motivation should examine all the factors affecting the decision to donate, including commitment to voluntary blood donor organizations. The aims of this paper are to verify if the motivational factors that influence the choice to donate blood in Italy are generally consistent with the findings from other countries reported in the literature and to focus on commitment to donor organizations as an additional factor. A sample of 895 whole blood donors completed a self-report questionnaire containing questions about: reasons for beginning to donate, people who influenced this choice, and level of commitment to voluntary blood donor organizations. The most frequently reported reasons for giving blood for the first time were "to help others" (56%), "influence of family/friends" (22%), and "social/moral obligation" (11.2%); commitment did not vary as a function of the leading motivation reported. Differences emerged between males, who more frequently reported having been influenced by parents and friends, and females, who referred more often to altruistic motives. The opportunity to check one's own state of health also played an important role (6.9%), especially for male donors. Overall, however, the decision to donate was primarily a personal choice (41.3%), although influence was also attributed to relatives (21.8%), friends (22.3%), and voluntary blood donor organizations (21.8%). The reported level of commitment to the donor organization was positively correlated with the number of total and annual donations made and number of new donors recruited.  相似文献

Although substantial research has examined the conflict that employees experience between their work and family roles, the literature has not investigated the prevalence and antecedents of work–family conflict for individuals who work at different levels of an organization. This study examines differences in work–family conflict (work interference with family and family interference with work) for lower-level and higher-level employees, the factors that might explain these differences, and the differential effect of resources on conflict across job levels. Results indicate that higher-level workers experience greater conflict in both directions than lower-level workers, and that work- and home-based resources are differentially related to the conflict experienced by employees who hold lower-level and higher-level jobs.  相似文献

It is known that number and space representations are connected to one another in numerical and arithmetic abilities. Numbers are represented using the metaphor of a mental number line, oriented along horizontal and vertical space. This number line also seems to be linked to mental arithmetic, which is based partly on arithmetic fact retrieval. It seems that number representation and mental arithmetic are linked together. The present study tested the effect of spatial contextual congruency between stimulus presentation and response key arrangements in arithmetic fact retrieval, using number-matching and addition verification tasks. For both tasks in Experiment 1, a contextual congruency effect was present horizontally (i.e., horizontal presentation of stimuli and horizontal response key alignments) but not vertically (i.e., vertical presentation of stimuli but horizontal response key alignments). In Experiment 2, both tasks showed a contextual congruency effect for both spatial conditions. Experiment 1 showed that the interference and distance effects were found in the horizontal condition, probably because of the spatial congruency between stimulus presentation and response key arrangements. This spatial congruency could be related to the activation of the horizontal number line. Experiment 2 showed similar interference and distance effects for both spatial conditions, suggesting that the congruency between stimulus presentation and response alignment could facilitate the retrieval of arithmetic facts. This facilitation could be related to the activation of both horizontal and vertical number lines. The results are discussed in light of the possible role of a mental number line in arithmetic fact retrieval.  相似文献

It is widely believed that advantages of hemispheric asymmetries originated in better cognitive processing, hence it is often implied that the relationship between hemispheric asymmetry and cognitive performance is linearly positive: the higher the degree of lateralization in a specific cognitive domain, the better the performance in a corresponding task. Yet, the empirical evidence for this notion is mixed and the statistical methods to analyze this relationship have been criticized. The present study therefore investigated the relationship between hemispheric asymmetries and cognitive performance in two behavioral tasks (a left-lateralized word-matching task and a right-lateralized face-decision task) in 230 participants (140 women, 90 men) by using two different approaches. Both methods correspondingly revealed that a relationship between hemispheric asymmetries and cognitive performance does exist. Contrary to a positive (linear) relationship however, the data could be best described by an inverted U-shaped curve. Although the optimal degree of lateralization seemed to be task-specific, a slight or moderate degree of hemispheric asymmetry achieved best cognitive performance in all tasks. Moreover, performances deteriorated towards extreme ends of lateralization (i.e., participants with either extreme left or right hemispheric biases). Taken together, the present study provides evidence against the notion that higher lateralization is related to enhanced cognitive performance.  相似文献

The article attempts to reconsider the relationship between Leibniz’s and Kant’s philosophy of geometry on the one hand and the nineteenth century debate on the foundation of geometry on the other. The author argues that the examples used by Leibniz and Kant to explain the peculiarity of the geometrical way of thinking are actually special cases of what the Jewish-German mathematician Felix Hausdorff called “transformation principle”, the very same principle that thinkers such as Helmholtz or Poincaré applied in a more general form in their celebrated philosophical writings about geometry. The first two parts of the article try to show that Leibniz’s and Kant’s philosophies of geometry, despite their differences, appear to be preoccupied with the common problem of the impossibility to grasp conceptually the intuitive difference between two figures (such as a figure and its scaled, displaced or mirrored copy). In the third part, it is argued that from the perspective of Hausdorff’s philosophical-geometrical reflections, this very same problem seems to find a more radical application in Helmholtz’s or Poincaré’s thought experiments on the impossibility of distinguishing distorted copies of our universe from the original one. I draw the conclusion that in Hausdorff’s philosophical work, which has received scholarly attention only recently, one can find not only an original attempt to frame these classical arguments from a set-theoretical point of view, but also the possibility of considering the history of philosophy of geometry from an uncommon perspective, where especially the significance of Kant’s infamous appeal to “intuition” can be judged by more appropriate standards.  相似文献

In this contribution we aim at anchoring Agent-Based Modeling (ABM) simulations in actual models of human psychology. More specifically, we apply unidirectional ABM to social psychological models using low level agents (i.e., intra-individual) to examine whether they generate better predictions, in comparison to standard statistical approaches, concerning the intentions of performing a behavior and the behavior. Moreover, this contribution tests to what extent the predictive validity of models of attitude such as the Theory of Planned Behavior (TPB) or Model of Goal-directed Behavior (MGB) depends on the assumption that peoples’ decisions and actions are purely rational. Simulations were therefore run by considering different deviations from rationality of the agents with a trembling hand method. Two data sets concerning respectively the consumption of soft drinks and physical activity were used. Three key findings emerged from the simulations. First, compared to standard statistical approach the agent-based simulation generally improves the prediction of behavior from intention. Second, the improvement in prediction is inversely proportional to the complexity of the underlying theoretical model. Finally, the introduction of varying degrees of deviation from rationality in agents’ behavior can lead to an improvement in the goodness of fit of the simulations. By demonstrating the potential of ABM as a complementary perspective to evaluating social psychological models, this contribution underlines the necessity of better defining agents in terms of psychological processes before examining higher levels such as the interactions between individuals.  相似文献

Muslims have never before occupied such a central position in the British media, given their general absence from more ‘normalised’ representational positions such as in popular soaps, literature and reality television. Recent studies reveal the primarily negative ‘hypervisibility’ of Muslims across the media, which has encouraged negative social representations. Drawing upon relevant concepts from intergroup threat theory and identity process theory, this paper argues that British Muslims are increasingly constructed in terms of a hybridised threat to the ethno-national ingroup, consisting of both symbolic and realistic aspects. This account offers a socio-psychological perspective by exploring the potential socio-cognitive and behavioural repercussions of exposure to representations of British Muslims as a hybridised threat. The focus upon identity processes among the non-Muslim British majority elucidates the identity implications of Islamophobic representations in the Press and some of the potential causes of Islamophobic prejudice. It is argued that the principles of continuity, distinctiveness and self-esteem are particularly susceptible to change as a result of such negative media representations. The transition from media representation to dominant social representation is discussed, in addition to the potential implications for intergroup relations.  相似文献

The present study examines the reliability, factor structure, and criterion-related validity of Hare (2003) Revised Psychopathy Checklist [PCL-R] in a Latin American forensic context. Brazilian male inmates (124) were administered the PCL-R, along with relevant subscales of an inventory of normal personality [Personality Factorial Inventory], an intelligence scale [Standard Progressive Matrices], and a semi-structured interview based in DSM IV. Criminal offence records were obtained from prison files. Several theoretical factorial structures for the PCL-R were tested and compared. A bifactor model with three factors, one general factor reflecting the overlap across all items, and two independent subfactors reflecting the unique covariation among particular groups of items, shows the better fit. Overall scores on the PCL-R correlated with the number of criminal offenses committed by participants. No significant correlations were found between PCL-R scores and personality or intelligence measures. It was concluded that the PCL-R is a reliable and valid instrument for the assessment of psychopathy in the Brazilian male forensic population.  相似文献
