Geometry Spaces of Constant Curvature: Spaces of Constant Curvature, Hardcover edition

This book contains a systematic and comprehensive exposition of Lobachevskian geometry and the theory of discrete groups of motions in Euclidean space and Lobachevsky space. The authors give a very clear account of their subject describing it from the viewpoints of elementary geometry, Riemannian goemetry and group theory. The result is a book which has no rival in the literature. Part I contains the classification of motions in spaces of constant curvature and non-traditional topics like the theory of acute-angled polyhedra and methods for computing volumes of non-Euclidean polyhedra. Part II includes the theory of cristallographic, Fuchsian, and Kleinian groups and an exposition of Thurston's theory of deformations. The greater part of the book is accessible to first-year students in mathematics. At the same time the book includes very recent results which will be of interest to researchers in this field.

Crises do not occur in cultural vacuums, but help often does. Good intentions are not enough. Lack of cultural understanding, sensitivity, and competencies can hamper and even harm the professional response to disasters. To help and heal, one must know and understand the cultural background of disaster victims. Ethnocultural Perspectives on Disaster and Trauma offers readers substantive knowledge in these three vital areas of disaster response.

In this pioneering volume, experts on individual and collective trauma experience, posttraumatic stress and related syndromes, and emergency and crisis intervention – share knowledge and insights on the cultural context of working with ethnic and racial minority communities during disasters. In each chapter, emotional, psychological, and social needs as well as communal strengths and coping skills that arise in disasters are documented for major minority groups in the United States including specific chapters on African Americans, Native Americans, Arab Americans, Asian Indians, Chinese Americans, Caribbean Americans, Latin Americans, Native Hawaiians, and Vietnamese Americans. Each chapter features information on:

• Demographics, major historical events, and core values of each population
• Important cultural insights, including communication styles, culture-specific disorders, and valid assessment instruments
• Therapeutic and healing traditions versus conventional medicine and therapy
• Perspectives specific to the population’s experience with disaster and trauma
• Authors’ recommendations for improving services to the population
• Practical appendices for readers new to the field

This unique volume is a cultural competency compendium that will increase to the effectiveness of all who respond to disasters. It will also be of interest and value to scholars, policy makers, and health professionals working in the areas of disaster management, crisis intervention, and trauma. Ethnocultural Perspectives on Disaster and Trauma points readers to what the editors call the path "beyond simple assistance to healing and the restoration of hope and meaning."
