"Errors in disease classification can give misleading inferences for covariate effects when the probability of error is itself related to the covariates. More accurate inferences are possible using supplemental data on both true and fallible disease counts at various covariate levels. We present a method for incorporating such supplemental data into disease rate regression and use it to show that, although observed intercountry differences in European cervical cancer mortality rates are exaggerated by errors in death certification, they are not completely explained by such errors." The data concern Belgium, England and Wales, France, and Italy.  相似文献

"Dissemination and marketing of census products were...major topics at the Thirteenth Population Census Conference of census directors from the Asian-Pacific region, held in Honolulu in December 1990. Drawing upon papers presented at the conference,...this article describes technological developments and marketing techniques being used in the region to increase the demand for census information."  相似文献

74 labor migrant families from various socioeconomic classes in Amman, Jordan were interviewed to examine changes in relationships among family members, extended family, and neighbors and their concerns about economic stability in the host country, Jordan, and the world market. Another purpose was to determine how current migration policies of the Arab oil-producing countries which prohibit labor migrants from bringing their families to the host country affect labor migration among families. The families consisted of either those who did or did not accompany the labor migrant. Overall labor migration affected unaccompanied families more than accompanied families, e.g., only 19% of the unaccompanied families reported increased family unity compared with 56% of accompanied families. Problems within unaccompanied families increased in 43% of the cases but in only 6% of the accompanied families. Many of these problems resulted in children dropping out of school which reflected the control fathers had within the family, separation, or divorce. Yet labor migration reduced family ties with extended family members and neighbors almost equally for both groups. Accompanied families were not as concerned about economic stability in Jordan as unaccompanied families (38% vs. 50%). Perhaps these families tended not to invest remittances received from the labor migrants working in Arab oil-producing countries in Jordan. Both groups were quite concerned about the economic stability in the host countries (66% and 72%, respectively) and the world market (59% and 62%, respectively), however. Since family unity suffers when families do not accompany labor migrants, it is suggested that oil-producing nations that depend on foreign labor should guarantee family unity as a human right.  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

Information about board-and-care homes reported in the media and in federal committee hearings indicates that they are shoddy and exploitative environments that do not provide adequate care. Research done in board-and-care homes in recent years, however, demonstrates that they can provide adequate care and a satisfying environment for some of the people they serve. Policy at the federal, state, and local levels should be guided by both the need to assure the health and safety of board-and-care residents and the needs of residents and operators identified in scientific studies.  相似文献

"A human capital framework is utilized to examine the economic progress of nine nationality groups of foreign workers [in Kuwait] using data from the 1983 national Labor Survey. The sources of earnings' variations of particular interest to us included different degrees of education and experience transferability, occupational affiliation and ethnic background. In general, the results derived from the analysis suggest that 1) foreign workers achieve a discernible economic progress as their residence lengthens; 2) the rate of economic progress varies depending on worker's education, home and Kuwait-specific experience, occupational status and ethnic background; and 3) about one third of the earnings inequality is due to unexplained factors including discrimination."  相似文献
