"The research is based on a study carried out between 1989 and 1991 in the three rural communities in the state of Morelos [Mexico] that included a socio-demographic survey and interviews. The methodological goal of the authors is to view nuptiality from demographic and anthropological standpoints.... The authors seek to pinpoint the elements that account for changes that have taken place in nuptiality, as well as to identify the impact of these changes on [descendants]." (SUMMARY IN ENG)  相似文献

"A bibliographical review serves to analyze the role of urban growth in patterns of international labor-force migration, as well as the effect of this migration on the development of the countries of origin, especially on their cities. While the review confirms the general idea that international migrants are either peasants or highly qualified personnel, it also shows that qualified workers are increasingly involved in international labor movements and that a great part of them come from large cities. It is to be expected that in these circumstances large cities of the countries of origin will become more integrated to international migratory systems." (SUMMARY IN ENG)  相似文献

In adopting the Health Insurance Portability and Accountability Act of 1996 (HIPAA), Congress made a series of small but significant steps toward improving access to health care benefits. The Act's centerpiece is its new requirements for group health plans and for the health insurance industry for assuring portability, access, and renewability of health insurance coverage. Of nearly equal importance is the pilot program established for testing the viability of medical savings accounts. Other health-related changes include adjustments in the rules governing duplication and coordinating of Medicare-related plans, recommendations with respect to privacy of health information of employees, an increase in the deduction for health insurance costs for self-employed individuals, and permission for unemployed persons to make withdrawals from IRAs and other qualified plans for certain medical services' costs. This article summarizes these and other key provisions of HIPAA.  相似文献

Two experiments tested the proposition that postevent questioning can lead to later increases in witness confidence without corresponding changes in witness accuracy. After a staged interruption in a college classroom, participants were questioned about the event 5 times over 5 weeks in Experiment 1 (n=57) and 3 times over 5 days in Experiment 2 (n=79). During the final questioning session, the participant-witnesses consistently reported higher levels of confidence for those items that had been subject to repeated postevent questioning than for those items that were asked for the first time, yet there was no difference in the accuracy of the responses to the two sets of items. Additionally, in all conditions the participant-witnesses were generally overconfident in their responses. These results suggest that repeated postevent questioning can cause eyewitnesses' subsequent confidence estimates to be artificially inflated.  相似文献
