The ability to utilize metaphor is presented as the normal stage in the development of the capacity to symbolize that is characteristic of the young adolescent. Symbolization is considered to be the basic structure through which the individual constructs a knowledge of the reality and of the self. Therefore, staying within the framework of the metaphor in treatment with the young adolescent is beginning where the client is but equally as importantly it is assisting the youngster to further develop both his symbolic capacities and himself. A case illustration is utilized to demonstrate both healthy and pathological usage of metaphorical language.  相似文献

Research on the traditionalist movement against abortion needs alignment with currents in historical sociology, the theory of social movements and the sociology of politics. The religious (specifically, Christian) basis of the right-to-life movement has attracted considerable attention in the literature. The movement is seen as a traditionalist bloc claiming to oppose secularization and return to customary restrictions. However the tradition in question appears to be a recent social construction. There is slim warrant in the actual traditions of Western religion for asserting a categorical right to life. As a result, the movement's ideology is best approached as the product of—rather than the antidote to—secularizing processes (including the demographic transition, discourse about rights, markets for symbolic entrepreneurs and the separation of church and state) and possibly as an unintended import from non-Western religion. Implications for traditionalism, the functions of religion, and the study of countermovements are explored. This case illustrates the value of attending to historical sequences and the external cultural environments of social movements.  相似文献

ARIMA (p, d, q) models were fitted to areal annual rainfall of two homogeneous regions in East Africa with rainfall records extending between the period 1922–80. The areal estimates of the regional rainfall were derived from the time series of the first eigenvector, which was significantly dominant at each of the two regions. The first eigenvector accounted for about 80% of the total rainfall variance in each region.

The class of ARIMA (p, d, q) models which best fitted the areal indices of relative wetness/dryness were the A R M A (3, 1) models. Tests of forecasting skill however indicated low skill in the forecasts given by these models. In all cases the models accounted for less than 50% of the total variance.

Spectral analysis of the indices time series indicated dominant quasi-periodic fluctuations around 2.2–2.8 years, 3–3.7 years, 5–6 years and 10–13 years. These spectral bands however accounted for very low proportion of the total rainfall variance.  相似文献

The authors describe a project, begun in 1981, to locate, list, and annotate all the published work based substantially on the census enumerators' books for nineteenth-century censuses for England and Wales. The results are currently available in a computerized file, enabling a variety of searches by topic, geographical area, and type of population. Information is provided on using the data and the computerized bibliography. The authors note that, subsequently, data for censuses of Scotland and Ireland have been added.  相似文献

This article examines interstate migration and labor force participation among White, American Indian, and intermarried Indian/White couples in the US. The results show that endogamous American Indian couples are much less likely to change states of residence than are the other 2 groups of couples. The effect of interstate migration on labor force participation does not vary across the 3 groups of couples. The implications of these results for the assimilation and internal colonial models of race relations and for federal Indian policy are discussed  相似文献

Two questions concerning the location of a single facility by a voting process are investigated for transportation networks:
  • - What is the maximum number of customers located on the network preferring some rival point over a voting solution?
  • - How does the average distance of the customers to the facility increase when a voting location instead of a Weber location is chosen for the facility?
  • Complete answers are given for general networks and for certain planar networks, viz., the so-called generalized cacti.  相似文献

    Abstract Both politicians and voters were asked to predict outcomesof two Oregon ballot measures in 1982. As expected, politicians'predictions always were closer to the mark than voters' were.Further, voters showed stronger signs of wishful thinking (the"Looking-Glass effect") in their predictions than did politicians.Using published preelection polls apparently improved politicians'accuracy in 1982, as well as voters' accuracy in a separate1984 survey. No other sources of data improved predictive accuracy.Findings have implications for theories of representative governmentand are consistent with a new theory of public opinion.  相似文献

    In this one-page statistical summary, data are presented for the USSR as a whole on fertility, mortality, and natural increase. The data are for five-year intervals from 1940 to 1980 and for single years from 1980 and are presented in terms of both totals and rates.  相似文献

    This paper demonstrates the need for a broad array of clinical services in treating the emotionally disturbed, mildly retarded youngster in the foster care system. A hypothesis suggests that cognitive deficits and borderline pathology are interrelated, and that treatment involves modifications of traditional therapeutic techniques. The definition of clinical is expanded to include seemingly concrete and environmental services, in addition to the office therapy session. Finally, some systemic impediments to effective treatment of the population are explored.This paper was completed as a requirement of the Post-Master's Program in Advanced Clinical Social Work of Hunter College School of Social Work.  相似文献
