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 effects of regulatory tools on organizational populations 总被引:6,自引:0,他引:6
One of the main activities of regulation is the control of market development by influencing the number of firms in an industry, their entry into an industry, and their exit from an industry. Population ecology is used as a framework for explaining both the direct and indirect effects of regulatory activity on entry, exit, and market structure. This framework is then used to derive specific propositions about regulatory effects on entry, exit, and market structure in the health maintenance organization industry. 相似文献

In the decade from 1950 to 1960, two quality-related processes--medical audit and total quality management--were being developed, one directly in the health care field and the other in the manufacturing sector. These processes remained isolated from each other until the mid-1980s. Each would have a separate but major effect on the health care industry. 相似文献

To change from punitive and legalistic QA to positive and productive CQI, both attitudes and methods must change. This is a difficult challenge, but potential rewards for both the organization and its individual members suggest that the effort is worthwhile and deserves high priority. Members of the executive/management team will likely turn to physician executives for guidance on how to proceed. 相似文献

Common sense has to do with problem solving. In the complexities of everyday human life, we are faced time and again with the need to solve problems. In fact, every situation we face, at least at the first exposure, requires some form of problem solving. When we want food, we have to solve a series of problems from acquisition to preparation to serving and eating. When we deal with organizational needs, problem solving is the daily fare. 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

RACE-OF-INTERVIEWER EFFECTS IN A PREELECTION POLL VIRGINIA 1989 总被引:1,自引:0,他引:1
All published preelection surveys of the 1989 Virginia gubernatorialcontest overestimated the vote share of the black candidateand eventual victor, Douglas Wilder. We offer a "social desirability"interpretation of the polls' inaccuracies and hypothesize thatclaiming support for Wilder was the socially desirable responsefor some whites, especially when the interviewer was black.We show a race-of-interviewer effect on the vote intention ofwhite respondents of 8–11 percentage points in a preelectionsurvey of Virginia voters. The effects were greatest among whiteDemocrats and among whites who were more uncertain of theirvote intention. We discuss the implications of these findingsfor race-of-interviewer research and for improving the accuracyof preelection forecasts in contests with black and white opposingcandidates. 相似文献
