This study was a meta-analysis of the relationship between personality and ratings of transformational and transactional leadership behaviors. Using the 5-factor model of personality as an organizing framework, the authors accumulated 384 correlations from 26 independent studies. Personality traits were related to 3 dimensions of transformational leadership—idealized influence–inspirational motivation (charisma), intellectual stimulation, and individualized consideration—and 3 dimensions of transactional leadership—contingent reward, management by exception–active, and passive leadership. Extraversion was the strongest and most consistent correlate of transformational leadership. Although results provided some support for the dispositional basis of transformational leadership—especially with respect to the charisma dimension—generally, weak associations suggested the importance of future research to focus on both narrower personality traits and nondispositional determinants of transformational and transactional leadership. A recent PsycINFO search revealed that 1,738 of the 15,000 articles (12%) published since 1990 on the topic of leadership included the keywords personality and leadership. Clearly, scholars have a strong and continuing interest in the dispositional bases

Yet, moral virtues are also sexually attractive. Darwin suggested that sexual attractiveness may explain many aspects of human morality. This paper updates his argument by integrating recent research on mate choice, person perception, individual differences, costly signaling, and virtue ethics. Many human virtues may have evolved in both sexes through mutual mate choice to advertise good genetic quality, parenting abilities, and/or partner traits. Such virtues may include kindness, fidelity, magnanimity, and heroism, as well as quasi-moral traits like conscientiousness, agreeableness, mental health, and intelligence. This theory leads to many testable predictions about the phenotypic features, genetic bases, and social-cognitive responses to human moral virtues. A

The authors used growth mixture models to study religious development during adulthood (ages 27–80) in a sample of individuals who were identified during childhood as intellectually gifted. The authors identified 3 discrete trajectories of religious development: (a) 40 % of participants belonged to a trajectory class characterized by increases in religiousness until midlife and declines in later adulthood; (b) 41 % of participants belonged to a trajectory class characterized by very low religiousness in early adulthood and age-related decline; and (c) 19 % of participants belonged to a trajectory class characterized by high religiousness in early adulthood and age-related increases. Gender, strength of religious upbringing, number of children, marrying, and agreeableness predicted membership in the trajectory classes. Results were largely consistent with the rational choice theory of religious involvement.

The authors conducted a comprehensive review to understand the relation between personality and aggressive behavior, under provoking and nonprovoking conditions. The qualitative review revealed that some personality variables influenced aggressive behavior under both neutral and provocation conditions, whereas others influenced aggressive behavior only under provocation. Studies that assessed personality variables and that directly measured aggressive behavior were included in the quantitative review. Analyses revealed that trait aggressiveness and trait irritability influenced aggressive behavior under both provoking and neutral conditions but that other personality variables (e.g., trait anger, Type A personality, dissipation–rumination) influenced aggressive behavior only under provoking conditions. The authors discuss possible relations between these patterns of aggressive behavior and the personality dimensions of Agreeableness and Neuroticism and consider implications for theories of aggression.

Practitioners are typically aware that organisational complexity is important to IT project performance however they are unsure of exactly what it comprises and how they should take it into account in their decision-making. This paper contributes to addressing the ‘what’ question by taking a multi-level conflict approach to understanding the relationship between individuals, groups and IT project complexity-an area in the literature so far unexplored and thus the basis of this literature survey and theory development. We first assess existing studies of conflict using semantic analysis to identify the basic components of conflict. We consequently examine the relationship between these components. Lastly we formulate a multilevel model of the phenomena to relate conflict to IT Systems Development Project (ISDP) complexity. The resulting model of conflict in ISDPs suggests that conflicts can occur at three different the levels: individual; intra-group; and inter-group. And that the following can be the objects of conflict: tasks,
