"The study investigates the departure from Australia of former settlers who arrived during the 1980 calendar year. The 1980 settler arrival cohort [consists] of 75,167 visaed migrants.... The study has three main aims: (i) to analyse departures from Australia of the 1980 settler arrival cohort with a view to gauging the success of Australia's immigration program in retaining settlers; (ii) to examine the retention rates of settlers with respect to characteristics...including age, sex, marital status, country of last residence, and settler eligibility category; and (iii) to consider implications of the findings." Australia's present immigration policy is discussed, previous research on return migration from Australia is summarized, and a detailed analysis of the departure data is presented. "This study found that by August 1984, 12.4 per cent of non-refugee settlers who arrived in Australia during 1980 had departed permanently but that only 0.6 per cent of the 1980 refugee cohort had done so." These figures represent a decline in immigrant departure rates since the 1960s and early 1970s. Small differences in departure rates by place of birth, age, and marital status, which may have demographic consequences if sustained over time, are noted. (SUMMARY IN FRE AND SPA)  相似文献

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 aim of this paper is to describe several methods for quantifying the amount of uncertainty inherent in population forecasts used to assess the impact of demographic processes on social security systems. Each method is briefly outlined, and its advantages and disadvantages are discussed. The primary emphasis is on stochastic population models, and the geographic focus is on the Federal Republic of Germany.  相似文献

This paper describes the major structural and historical dimensions of health ideology and praxis in the Canadian Arctic. It examines the problems that occur when primary care services exclude their clients from meaningful involvement in planning and administration. It argues that the structure of health services in northern Canada reflects an internal colonial political economy which is characteristic of most Fourth World situations.  相似文献

The author examines developments in marriage patterns in Bangladesh in light of social, cultural, and economic conditions. Previous literature on the subject is used to discuss Muslim marriage, Hindu marriage, child marriage, mate selection and social mobility, and the question of a marriage squeeze. "The analysis presents evidence that the society is experiencing a change in its family formation, mating process and family type. This transition is to some extent towards the characteristics of [the] Western World, but in a poor economy. Part of this transition is due to the effect of modernization and part due to increasing poverty."  相似文献

"This paper seeks to (1) identify socioeconomic variables that are expected to generate fertility differentials; (2) hypothesize the direction and magnitude of the effect of each variable by reference to a demand-for-children model; and (3) test empirically the model using evidence from Costa Rica. The estimates are obtained from a ten-percent systematic random sample of all Costa Rican individual-family households. There are 15,924 families in the sample...." The authors specifically seek "to capture the effects of changing relative prices and available income and time constraints on parental preferences for children. Least-squares estimates show statistically significant relationships between household fertility and opportunity cost of time, parental education, occurrence of an extended family, medical care, household sanitation, economic sector of employment, and household stock of nonhuman capital."  相似文献
