As nations become increasingly diverse and globalises, diversity-related issues are posing greater and greater challenges to business managers, non-profit and government officials, and academic administrators world-wide. They require fundamental changes in the way people think and act, or they may end up being divided rather than united. As a consequence, suffering arises from misunderstandings, distrust and serious conflicts not necessarily serving their own interests. This book examines some of the most important issues related to diversity along with various disciplinary perspectives that may help to deal with those issues.
