The China Family Planning Association was set up in May 1980 as a nongovernmental organization under the leadership of the Communist Party of China. Funds come from the government, international organizations, and individual or community donations. 13 branches have been established so far. The Association has contributed to publicity, education, and research: members have given lectures on family planning, genetics, and population theory, and have helped develop contraceptives. The lectures on population problems have been published. In addition, the Association's periodical "Ren Sheng" is published bimonthly, and has a circulation of 125,000. Meeting have been convened for the exchange of information and experience among family planning workers. The Association organized tripartite seminars with IPPF and JOICFP in June and October, 1983. Under the auspices of the Association, 8 trainees have been sent to the David Owen Center in the United Kingdom for a Year's study, and 1 trainee was sent to the London School of Hygiene and Tropical Medicine. The Association was accepted as a full member of the IPPF at the conference held in Nairobi, Kenya, in November, 1983.  相似文献

Using a sociodemographic model of the determinants of illegitimacy rates, a multivariate regression analysis of annual change in age-specific Swedish illegitimacy rates is applied to the 1911-74 period. The proxy measure of change in sexual activity was significant for all age groups. Legitimation rates for out-of-wedlock conceived births were significant for all ages except teenagers, and the final predictor, women's status, was significant for all ages except women 35-44. Explained variance for annual change was highest among ages 20-24 (66%), 25-29 (66%), and 30-34 (63%) and lower among teens (34%) and women 35-44 (47%). These results support earlier research that used a sociodemographic model to explain post-World War II change in cross-national illegitimacy rates among 23 developed countries.  相似文献

This article examines in depth the strategic implications for those States who have recently declared 200 mile off-shore resource management zones. The authors, in a comprehensive and stimulating paper, examine the implications of so-calling a nation's offshore limit. It is an appropriate name for a nation's offshore limit since the primary reason for many nations declaring a 200 mile limit has been the abundance of resources which have often been found within those limits either in the sea or the sea bed itself. This paper reviews the current background of off-shore resource management and outlines suitable roles for adoption by the coastal States in the management of their off-shore renewable and non-renewable resources. Furthermore, it examines the contentious but nonetheless central issue of the benefits and costs which accrue through coastal state jurisdiction. The authors also examine an appropriate resource management process and the implications of resource use conflicts within the off shore limit as well as defining these conflicts on the basis of ‘stakeholder’ interests and introduces a new concept of the maximization of economic equity amongst competing stakeholders. The problem remains that the measurement of economic equity perhaps leaves the States concerned within a situation of only having defined the problem; the political process has then to deal with any reallocation measures that may be deemed appropriate.  相似文献

As a guide for how to select a new executive director, a family agency adopted the search committee process from higher education. The approach included clarifying agency goals and the director's qualifications, a board-staff screening, and interviews held jointly with public representatives before final board selection.  相似文献

The aim of this paper is to widen the clinician's understanding of a narcissistic type, the solipsist (one alone with the self) who is treatable because he or she is the healthiest of narcissists yet a challenge to psychotherapy because the solipsist allows no one to be with him or her. Countertransference is discussed as a primary factor for the therapist to understand and control. The handling of the transference is seen as the key to therapeutic success and is illustrated by case examples.  相似文献
