In this paper the robustness of Brass's child-survivorship indirect mortality estimation technique is investigated. An analytical method is developed for studying the error or bias caused in indirect mortality estimates by poor data, badly chosen model functions, and specific demographic assumptions that are often violated in practice. The resulting analytical expressions give insight into the rationale of indirect methods, the conditions under which they are robust, and the magnitude of errors that occur when specific assumptions are violated. 相似文献

This article examines child mortality as an indicator of the quality of life among migrants living in Brazilian Amazonia in 1980. I focus on migrants in the frontier states of Pará and RondÔnia, which experienced rapid settlement during the 1970s. The key question here is the effect of settlement location on child mortality rates. While RondÔnia had lower ratios of population per public health establishments and personnel than Pará, RondÔnia nonetheless exhibited a higher malaria prevalence in 1980. I therefore attribute locational differences in child mortality to environmental factors important to malaria transmission rather than to health care infrastructure. The findings from multivariate regression analysis show that net of the effects of human capital, migration history and migrant living standards, settling in Pará rather than RondÔnia resulted in significantly lower rates of child mortality. These findings suggest that environmental factors coinciding with location of frontier settlement had important consequences for the living standards of migrants in the Brazilian Amazon. 相似文献

Attention is given to population and growth and the impact on the environment and resources in China. Policies for managing the environment and instituting population education are also addressed. The first position paper of the National Environmental Protection Agency (NEPAC) on June 2, 1990 is summarized. The population of China was 1.11 billion in 1989. The rate of growth in 1988 was 14.2/1000 in 1988. 91% live in the southeast on 43% of the land. Land area is 9.6 million square miles. 65% can be made arable, and 14% is cultivated. China has 7% of the world's arable land and 20% of the world's population. Population growth has reduced arable land/captia. The impact on forests has been deforestation. 13% of land is currently forested, and timber reserves encompass 9.14 billion cubic meters, or 9 cubic meters/person. The demand for firewood and timber will increase. The impact on grasslands has been overgrazing and desertification at a current rate of 1560 square kilometer/year. The impact on energy resources is a greater demand for coal which will increase and thus increase pollution of the environment. The impact on water resources is greater demand and increased pollution. Water resources are 2700 cubic meters/person or less than the world average. 26.8 billion tons of waste water were industrially discharged out of 36.8 billion tons. 436 of the 532 rivers are polluted. The impact on the environment is a decreased standard of living. NEPAC reported that air pollution was slightly reduced in 4% of the cities in 1988, increased in 4%, and stable in the remaining cities. Water quality improved through the lowering of industrial waste water discharges, but 72% of river segments are still above the standards. Each major river system is discussed. Noise increased, and industrial solid wastes increased. Forest reserve is 9.141 billion cubic meters; the man-made forest has increased. The loss of grasslands is .13 million hectares/year. Cultivated land is 95.72 million hectares, but 100,000 hectares/year are damaged by natural disasters and 6 million are polluted by industrial wastes. 606 nature preserves have been established. In 1989, a complete legal system of environmental protection was established and investment increased. 相似文献

"After introductory comments on the theme of ?ageing east and west', this paper looks at trends in ageing and responses to ageing over time, with particular reference to European experience. The evidence is reviewed in historical, cultural, religious, political and ?social political' perspective. Attention is drawn to the different patterns of experience and of policy responses characteristic of the different countries and regions within Europe both past and present. The paper concludes with a review of [the] latest trends and prospects in ?community care', which could signal a seeming point of convergence between east and west." 相似文献

Based on interviews conducted with eight lesbians, this paper explores how the intersection of gender, sexual identity, race, ethnicity, and class affect lesbians' feelings about their bodies. Their responses suggest that, while being female has a strong effect on lesbians' feelings about their bodies, issues of race, acculturation, and class also affect body image. Lesbian feminism and S/M politics also appear to play a significant role in lesbians' body image. These findings highlight the limitations of existing theories about body image and call for a more complex theory incorporating a more diverse range of experiences. 相似文献

By the mid-nineteenth century, the north east of England was home to the fourth largest Irish settlement in England. The 1851 census makes it possible to identify key features of this post-famine community and provides a basis for the exploration of non-quantitative sources. The Gateshead Irish community was the third largest in the north east, behind Newcastle and Sunderland. The census data can establish such key features as the spatial distribution of the Gateshead Irish, their occupational profile, age distribution, household size, marital status and the extent of intermarriage between the Irish and the host community. It will be shown that the concept of the ghetto does not apply to the Irish; that they were overwhelmingly employed in unskilled work; that they were, in general, older than the host community; and that there were a significant number of cases of intermarriage between the Irish and English. 相似文献

Abstract The present study was based on data collected (separately for husbands and wives) from 365 couples to determine levels of consensus on a series of variables related to the family forming process. Following Scheff (1967), consensus was operationalized as both agreement and coorientation in the marital dyad. The data generally indicated low levels of consensus on such variables as contraceptive efficacy, desired family size, child spacing, unwanted pregnancies, communication with spouse, and levels of alienation. The results are discussed within the framework of family planning and effective fertility control. 相似文献

Abstract This paper assesses the male contribution to contraceptive mismanagement and unwanted pregnancy. The subjects were 109 students at the University of Melbourne. A high incidence of risk-taking was reported, and almost one-fifth of the sexually experienced men stated that they had been involved in an unwanted pregnancy. A small group of these reported more than one such incident. The underlying reasons for poor contraceptive technique seemed to be related to two beliefs: that contraception is a female responsibility, and that sexual intercourse should be entirely spontaneous and unplanned. 相似文献
