This definitive guide encompasses past, present, and future issues of theory, research, and practice in areas of interest and specialization in aging, and represents current trends of thought on gerontology, the science of and associated practices with the elderly. This volume is a collection of articles dealing with the psychological, social, and cultural domains affecting older people and contains general biomedical understandings and practical/clinical applications. The contributors broadly outline some of the most relevant academic issues, including cross-cultural perspectives on age and aging; past and future trends in life expectancy with underlying explanations; innovations and advances in research design and methodology in the study of the aging process and the effects of age as a variable; and past and current theoretical perspectives on the psychology and sociology of aging. Some pertinent concerns for practitioners and clinicians are addressed, such as successful counseling therapies with older adults and changes in social work and rehabilitation practice with the elderly. The thought-provoking chapters provide a wide-sweeping, multidisciplinary review of a rapidly expanding field of interest and represent a definite desire among the contributors to evolve a theoretical apparatus and a related, applied arena of endeavor. This important work on a significant and timely issue of concern will broaden our understanding and awareness of the rising number of positive efforts within gerontological studies now being derived from diverse disciplinary roots. The reader will find articles on subjects of particular interest, such as the Biology of Aging, the Psychology of Adult Development and Aging, Rehabilitation of the Elderly, and Social Work and Aging. An extraordinarily detailed reference, this work will be a valuable resource for gerontologists, social workers, psychologists, and doctors specializing in geriatrics.
