Ferraro GP 《International journal of sociology of the family》1991,21(2):89-128
"This paper examines one set of relationships central to the Swazi household--marriage and conjugal roles--and how those relationships have changed over the last half century. Information has been analyzed on such topics as types of marriages contracted, the age at marriage, choice of spouse, attitudes towards and participation in polygyny, the nature of conjugal roles, and the question of divorce. This study has drawn upon a wide range of sources including (1) an analysis of civil records from the office of the District Commissioner in Manzini, Swaziland; (2) data collected previously by other social scientists; and (3) survey data gathered especially for this study. The study concludes that while changes have occurred, many traditional patterns of marriage and family continue to be important in contemporary Swazi society." 相似文献

The challenge of world health 总被引:1,自引:0,他引:1
2 development specialists have expounded on the demands world health has placed on public health. Striking declines in infant and child mortality occurred with the advent of biomedical and technical interventions in developing countries after World War II. At the same time, these interventions promoted longer lives by curing and/or treating chronic diseases in developed countries. In the 1970s, however, it was apparent that the hospital based, curative approach could not meet health needs and was very costly. In developed countries, biomedical and social sciences showed that chronic diseases did not occur due to modernization but from unhealthy behaviors, diet, and lifestyle. In fact, in 1975, the US Centers for Disease Control announced that unhealthy lifestyles contributed to 50% of all deaths while the medical system was responsible for only 11%. The US and other developed countries then began to promote healthy lifestyles, and in the 1980s, considerable improvements in health occurred, especially among adults. Developing countries which depended on the Western medical model did not experience health gains in the 1970s. Yet developing countries where health systems concentrated on carrying essential services to all people and promoted basic hygiene and sound dietary practices continued to achieve considerable health gains. In 1978, WHO an UNICEF hosted the International Conference on Primary Health Care in Alma Ata, the Soviet Union to hold these developing countries with community based health systems as models of primary health care (PHC). The 1980s witnessed the spread of PHC especially in the form of child survival which focused on oral rehydration therapy and breast feeding. The biomedical and social sciences are needed to move this health policy and program strategy forward. Governments must see to policies that promote healthy people. Political will is needed to make human welfare a high priority. 相似文献

Recent trends in the process of stratification 总被引:1,自引:0,他引:1
Using the 14 annual cross-sections from the General Social Survey, we specify a "basic model" of attainment and describe the year-by-year fluctuations in its parameters. The results are partially consistent with theories describing the gradual growth of universalistic patterns of stratification and mobility. Under a linear model of educational achievement, we find that the direct effects of race are weakening and the returns to class-based advantages are declining in tandem. The contours of the socioeconomic "gender gap" are also changing in important ways, with the male intercept declining at a rapid pace and the female term registering small and insignificant year-by-year gains. At the same time, the returns to experience and schooling are increasing for men, whereas the corresponding returns for women have remained stable over the 15-year period. This pattern of interaction effects implies that the size of the gender gap varies over time and across different population groups. 相似文献

Brungardt MP 《Latin American population history bulletin》1990,(18):2-8
The author discusses three of the six national censuses taken during the ninteenth century in Colombia--those for 1835, 1843, and 1851. The focus is on the importance of macro patterns generated by the data, the methods recommended to overcome the problems of the censuses, and ways to make the information useful for historical demography. 相似文献

Subjects imagined situations in which they reported enjoying themselves either alone or with others. Electromyographic (EMG) activity was recorded bilaterally from regions overlying thezygomatic major muscles responsible for smiling. Controlling for equal rated happiness in the two conditions, subjects showed more smiling in high-sociality than low-sociality imagery. In confirming imaginary audience effects during imagery, these data corroborate hypotheses that solitary facial displays are mediated by the presence of imaginary interactants, and suggest caution in employing them as measures of felt emotion.Avery Gilbert and Amy Jaffey had compelling insights throughout the course of study.

Doctors are not health care providers, and medicine is not a commodity. To practice medicine well, the doctor must attend to each patient as a whole person and be faithful in giving care when cure is not possible. 相似文献
