Book excerpt: An Introduction to Social Policy explores essential welfare topics, themes and issues for students studying social policy or related disciplines such as sociology, social work, or nursing and social care. - Part One examines key concepts including welfare, social justice, diversity and health and well-being. - Part Two explores policy issues in relation to key stages of the lifecourse. - Part Three takes a comparative perspective, discussing the international issues and supranational bodies that impact on British and European social policy today. The concise chapters define the key terms and outline the central debates, giving students a fundamental foundation for their degree. Chapter overviews and summaries guide readers through the book, and questions for reflection conclude each chapter to test readers' knowledge. This book is essential reading for all students of social policy and the social sciences, as well as those taking joint honours programmes in social work, sociology, criminology, politics and social care.
