Michael A. Cavanaugh 《Sociological Forum》1986,1(2):251-283
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

A fact-gathering, experimental game proved to be an effective instrument in the needs assessment phase of an adolescent sexuality educational program aimed at low-income females. The game ("Family Few"), which covered the topics of menstruation and reproduction, was played by 35 Black, Hispanic, and white females aged 13-16 years recruited from medical and psychiatric clinics in Miami, Florida. The goals of the game were to elicit terminology used by participants, identify and correct misconceptions and misinformation, and determine if learning could occur. Although 57% of participants reported prior exposure to formal sex education, misinformation about the need for activity curtailment during menstruation and the importance of early pregnancy detection was widespread. Group members believed they needed to restrict activities involving physical exercise, sexual relations, water, and cold during menses and were not likely to seek medical or family consultation regarding a missed period until the end of the 1st trimester of pregnancy. Also evident was a need for accurate information on the side effects, risk factors, benefits, and effectiveness of contraceptive methods. The group responses enabled the sex educators to prepare a culturally responsive, developmentally oriented curriculum for further work with disadvantaged female adolescents. The group process was ranked highly on the Likert Scale by these teenagers as an enjoyable, useful means of information dissemination and problem solving. 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

In the introduction to this special issue on temporary worker programs, the author defines the term temporary worker and reviews worldwide research, writings, and policies to date pertaining to temporary workers. Labor market and economic effects, socio-administrative conditions, and effects on the labor-sending societies are discussed. Noting that mutually exclusive arguments are presented within one issue of the journal, the author introduces the authors of the individual articles and their subjects. It is determined that the temporary worker phenomenon is now global and that having an understanding of these workers is increasingly central to understanding key socioeconomic and political processes affecting modern industrial and nonindustrial societies. 相似文献

An analysis of the foreign population in Kuwait shows that foreign nationals make up 60 percent of the population and 78 percent of the labor force in Kuwait. The implications of these figures for the Kuwaiti labor force are discussed by analyzing the occupational structures of Kuwaitis and non-Kuwaitis. "Structural analysis of the labor force indicates that 62 percent of Kuwaiti males are concentrated in administrative and service occupations while their percentage in sales and production work has declined during 1970-80. This demonstrates the need for reorienting educational/training programs and changing Kuwaiti attitudes towards manual work to ensure the realization of the 'Kuwaitization' process, and balance the nationals with foreign nationals." mortality has stabilized at relatively high levels and there is resistance to family planning. The author concludes that the main cause of the stalling of the demographic transition process is to be found in the role of the state and the dynamics of the social structure and that "demographic trends will depend more on the changes in social structure, land reforms, and response of the formal governing system to the needs of the underprivileged sections of the society, rather than on the health and family planning policies." 相似文献

"This article highlights important developments in the character of temporary worker flows to Canada between 1973 and 1985 through the use of unpublished data and new measures for analyzing this data. The number of employment authorizations are converted to person years to indicate the overall labor market impact of temporary worker flows and this measure is employed in an analysis of unpublished data from Employment and Immigration Canada. The analysis reveals that a significant and growing proportion of employment authorizations are exempted from governmental procedures which link the admission of temporary workers to the Canadian labor market." Reasons for these exemptions and policy implications are discussed 相似文献

The authors construct a theoretical framework for analyzing factors influencing international refugee movements. "On the basis of detailed case studies by the authors of the principal refugee flows generated in Asia, Africa, and Latin America from approximately 1960 to the present, it was found that international factors often intrude both directly and indirectly on the major types of social conflict that trigger refugee flows, and tend to exacerbate their effects. Refugees are also produced by conflicts that are manifestly international, but which are themselves often related to internal social conflict among the antagonists." 相似文献

According to recent evidence, adoptive placements that do not work out are increasingly common. This article reviews research on rates of, and contributors to, adoption and "foster-adoption" disruptions and dissolutions. Implications for practice are included. 相似文献
