A family-based, multi-system intervention is described as a response to three years of an adolescent's school failure. In a case study describing an unmotivated family, unmotivated school, and systems-oriented helpers, an intervention plan is developed that is directed toward improving the adolescent's school behavior and performance. Family therapy occurred concurrently with those interventions. A family-trained psycho educational consultant is employed to mediate between family and school to avoid disturbing the integrity of the therapists relationship with the family. Short-term effects of these procedures are described. 相似文献

The therapeutic relationship is seen as a mutual experiencing of self and other which is growth-promoting for the therapist as well as the patient. Work with a borderline woman during a period of two years evoked strong countertransference reactions in the therapist who, at times, experienced the patient as a mirror. A beginning sense of cohesion in the patient's highly fragmented sense of self found a parallel in this beginning therapist's developing professional identity. 相似文献

Estimation of nonlinear functions of a multinomial parameter vector is necessary in many categorical data problems. The first and second order jackknife are explored for the purpose of reduction of bias. The second order jackknife of a function g(.) of a multinomial parameter is shown to be asymptotically normal if all second order partials ?2g( p )?dpi?pj obey a Hölder condition with exponent α>1/2. Numerical results for the estimation of the log odds ratio in a 2times2 table demonstrate the efficiency of the jackknife method for reduction of mean-square-error and the construction of approximate confidence intervals. 相似文献

The level of labor force participation among Latin American women, when compared with participation rates for other countries, is the lowest in the world. Only 20% or less of women 10 years of age and older are economically active. This level did not change much between 1950 and 1970. Few women work in agriculture. The following factors are considered for their effect on labor force participation of urban women: marital status, education, income, and the structure and stage of development of the society. Married women have a low participation rate. More highly educated women are more likely to work, but there must be demand for their work services. As the economy of various countries has progressed, female participation in domestic services has decreased, in industry has remained constant between 1960 and 1970, and in social services has expanded. It is concluded that work participation for married women will only increase with the following changes: 1) improved educational opportunities for women; 2) structural change and modernization in the economy; and 3) reduced family fertility. Changes in the first 2 factors are more important than reduced fertility. Since 1960, only Chile and Costa Rica have had a 25% decline in fertility rates. 相似文献

Politicians and decision-makers in both developed and developing countries have sought to maximize economic growth on the basis of the belief that this leads to advances in the quality of life. This paper seeks to test whether this belief is well-founded. An application of the Diffusion Index to time-series data collected from a rapidly growing, low income country demonstrates that while higher national income makes for greater welfare the rate of welfare enhancement is almost independent of the rate of national income growth. On the basis of these findings, it is argued that the Gross National Product by itself may not be used as a reliable measure of human welfare. Finally, this paper suggests that in order to provide the maximum quality of life for the members of a given society, its national policy should be based on a much broader conception of welfare than is currently implied by the idea of GNP growthmanship. 相似文献
