This twenty-seventh volume of Research in Organizational Behavior carries forward the tradition of high-level scholarship on a broad array of organizational topics. Like many previous volumes, this collection is truly interdisciplinary, with chapters ranging from personality and decision making in organizations, to interpersonal dynamics such as helping and group process, to organizational-level analyses of legitimization and change. Each of the essays is well-reasoned, thoughtful, and provocative-- proving, once again, that the field of organizational behavior is flourishing in both its depth and scope.
