This book on business psychology—particularly organizational leadership—crosses industries, continents, and business environments: it includes 45 précis on emerging theories of leadership; ethical and cultural considerations; group and team leadership; leadership self-development; management philosophy and practice; organizational diagnosis and cultural dynamics; personality and lifespan in the workplace; professional development; qualitative research methods; psychological, socio-cultural, and political dimensions of organizations; the role of technology in organizations; strategic change management; and systems theory. The material ranges widely but is pithy: each précis offers in easy bites the latest "take" on the subject, drawing from popular textbooks, recommended readings, case studies, group exercises, personal experience, and self-reflection; each was written as a key to understanding and change with an eye to re-imagining leadership in the 21st century. Both rigorously researched and entertaining, this book addresses the fast-changing realities of organizational leadership in domestic and international settings across the private, public, and nonprofit sectors: it will serve as a valuable quick-access resource for practitioners and students.
