The author describes topics included in a study of spatial, social, and occupational mobility in Poland. These include rural migration, the effect of the family life cycle on migration, the social impact of migration, the effect of migration on spatial distribution, and migration prospects until the end of this century. 相似文献

G Hekma 《Journal of homosexuality》1986,13(2-3):43-55
Various styles of "male love" occurring in the 19th century are introduced. Locations and public ordinances relating to these styles of love are discussed. The development of the homosexual role is broached along with the question of whether attitudes and laws of the 19th century were responsible in part for the development of normative expectations for homosexuality which might in turn have repressed its growth. 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 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

"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

Puerto Rican migration to the US has been a more or less continuous process since 1917. The perspective of viewing return migration as a circulation process suggests that there are entries, exits, and reintergration into the metropolitan labor market. This study explores the circulatory movements of Puerto Rican families, events that influence the adaptation process when returning to Puerto Rico, and cultural identity aspects. Data collected by means of 2 research instruments that were administered to the respondents simultaneously were used: 1) a life history matrix and 2) an open-ended questionnaire. These interviews outlined the principal problems of adaptation as mentioned by the circulating migrants. The most difficult problems to adjust to were economic and employment (58%), followed by social acceptance (23%), education (17%), and language (15%). Transportation, medical services, and recreational facilities were also problems mentioned as being significant. It is expected that a great majority of migrant laborers will go to live in immigrant residential locations in large US cities. It is also expected that these migrants will meet with certain value conflicts by living in urban ghettos. These families will have serious difficulties finding economic stability and will possibly consider migrating once again as an alternative to their social reality. This study illustrates that: 1) the migrants return in family groups; 2) they face discriminatory problems in employment agencies and schools; 3) they look forward to a formal education as a means of social mobility; 4) they identify themselves with values, habits, and Puerto Rican traditions; and 5) they value the quality of life in Puerto Rico. 相似文献
