Over the past ten years research in leadership effectiveness has moved towards identifying the leadership competencies and leadership roles. Leadership competencies are knowledge, skills, abilities and behaviors of individuals. Today's global environment is characteristically dynamic, complex and diverse, but there are inadequate leadership skills such as in the academic environment. In this book the competencies include organizational strategy, resource management, communication collaboration, higher education advocacy, and professionalism and leadership roles are three major roles of interpersonal contact, information processing, and decision making. The purpose of this book is to examine the relationship between leadership competencies, roles and Effective Academic Leadership Styles (EALS). Leadership effectiveness is obtained from estimates of standardized regressions weights in Structural Equation Modeling (SEM).
