Everett (1982a) has proposed a graph theoretic technique for analysing social networks. It is not usually possible to apply this method to data which contain a large number of interlocking cycles. We demonstrate a technique which overcomes this problem by referring to the data analysed by MacRae (1960).  相似文献

The Ago General Hospital in Legaspi City of the Philippines was opened in 1965, antedating the national family planning movement by 5 years. The 180 bed hospital integrates family planning into the overall hospital service; sterilization is the main method used. Of the 3600 patients per year, 15% are family planning acceptors. The hospital employs 3 family planning strategies: inhospital, out patient and supportive. Inhospital strategies center on sterilization counseling and motivation. The counseling sessions include patient education. Primary targets include high risk pregnancies and young couples with a lot of children. Outpatient strategies include a referral system involving hospitals and agencies with family planning programs, lectures for community organizations and personal visits to other clinics and rural health units. The hospital's mobile clinic, staffed mainly by students, provides information, deworming, and pediatric services to the community. Supportive program strategies consist of mass communication, and an acceptor's club for previous acceptors of sterilization. These clubs meet regularly to share and discuss experiences.  相似文献

The outreach officials of the National Population Program of the Philippines, with its 4 basic functions of research, training, information-education-communication, and clinic services, are trying to solve pressing problems which have been an outgrowth of developments of the early 1970s when population and family planning concepts were integrated into other government programs. Given the task of attacking these problems and coordinating the whole program was the newly organized Commission on Population (Popcom). The organizations which had their own programs cooperated with the government agencies. Initially thought of as workable, the early strategy was soon found to be inadequate, and in July 1975, Popcom implemented an integrated development approach in population work. The strategy is complex, and as it undergoes refinement, the program may well profit from the experiences or lessions gained by a number of agencies in carrying out population/development activities. The approach used by the Office of Nonformal Education of the Philippines Rural Reconstruction Movement is seen as potentially helpful to the outreach project in developing 3 types of leadership in order to properly integrate or link private and public agencies, and ensure a continuing development program: political, educational, and technical. It is stressed that outsiders can help, but it is the community which must basically do the job themselves. So different government technicians are trained so that they can effectively train other people from the community, and do it in such a way that the program will be continuing and self-releasing.  相似文献

The author assesses the patterns of family extension in Peru by examining variations in family composition over the family life cycle. The amount and type of extension among Peruvian families at successive stages of family development are examined. The relative importance of general overlap and of child and spouse replacement mechanisms as processes that help to ensure the viability of residential family units is studied. The empirical analysis is based on a 1970-1971 survey of a national sample of Peruvian households  相似文献
