This twenty-sixth volume of "Research in Organizational Behavior" presents a set of well-crafted and thoughtful essays on a series of research topics. They range from efforts to redirect the study of leadership, to analyses of interpersonal relationships, to considerations of cross-cultural issues in organizing work, to discussions of institutional and environmental forces on organizational outcomes. Each of these essays includes a thorough review of the relevant literature, and more importantly, pushes that literature forward with new conceptual analysis and theory. In short, these essays continue the spirit of 'rigorous eclecticism' that has exemplified the annual publication of ROB. As a collection, this year's set of essays provides a healthy advance for the field of organizational behavior. They are examples of serious scholarship that extend and challenge our current thinking about organizations and the behavior of its participants. Many of these chapters will take their place among the best presented by the "Research in Organizational Behavior" series.
