This study examines the relationship between knowledge strategy (exploration or exploitation) and performance, and the possible moderating role of external environment variables. Results from a sample of small manufacturing firms indicate that exploration and exploitation are distinct and complementary constructs. The relationship between exploration and performance is linear and positive, while the relationship between exploitation and performance is concave, indicating that there is a point at which focusing on exploitation leads to reduced returns. Additionally, we find that the competitive environment moderates the relationship between exploitation and performance, such that exploitation has a stronger impact on performance in stable and high-tech environments than in dynamic and low-tech environments. Exploration also has a stronger impact on performance in high-tech environments than in low-tech environments.

The cognitive-affective model of the stress response provides a framework for making inferences about individual differences in stress propensity and levels of resultant strain. A new cognitive-affective conceptualization provides a means of analyzing mediating processes affecting psychological and physiological reactions to stressors. The model also facilitates examination and understanding of a latent cognitive-affective stress propensity construct that moderates the relationships between stressors and strain. Propositions are presented with the intention of stimulating further research.

This study identifies antecedents of two specific dimensions of organizational citizenship behavior, altruism (OCBI) and civic virtue (OCBO), in a sample of Arab employees working in Kuwait. Results indicate that a collectivist orientation is a significant predictor of altruism and that procedural justice and job satisfaction are significant predictors of civic virtue. Additionally, respondents indicate that both altruism and civic virtue behaviors are more likely to be perceived as in-role than extra-role behaviors by study participants. Findings provide additional insight into the relevance of OCB and its antecedents in organizations within an Arab cultural context and the resultant implications for managerial processes and decisions.

This article draws from the current literature to examine problem-based learning (PBL) as a management education tool, and provides an example of how to incorporate PBL into an undergraduate international management course. Also included are an explanation of, and specific guidelines for, a PBL exercise focused on the analysis of "country risk" (political/economic risks) for potential foreign direct investment. Additionally, the benefits and unique challenges of successfully implementing this type of exercise are discussed.
