Gerontology
Gerontology is the study of the social, cultural, psychological, cognitive, and biological aspects of ageing. The word was coined by Ilya Ilyich Mechnikov in 1903, from the Greek γέρων, geron, "old man" and -λογία, -logia, "study of". The field is distinguished from geriatrics, which is the branch of medicine that specializes in the treatment of existing disease in older adults. Gerontologists include researchers and practitioners in the fields of biology, nursing, medicine, criminology, dentistry, social work, physical and occupational therapy, psychology, psychiatry, sociology, economics, political science, architecture, geography, pharmacy, public health, housing, and anthropology.
Management
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. The term "management" may also refer to those people who manage an organization.
Management
Management is defined here as the accomplishment of desired objectives by establishing an environment favorable to performance by people operating in organized groups. Each of the managerial functions (planning, organizing, staffing, , directing, and controlling) is analyzed and described in a systematic way. As this is done, both the distilled experience of practicing managers and the findings of scholars are presented. This is approached in such a way that the reader may grasp the relationships between each of the functions, obtain a clear view of the major principles underlying them.
