"The aim of this paper is to examine the effects of the work permit today [in the United Kingdom], using official data. It first reviews the operation of the [labor migration] system and describes the main schemes incorporated. Then, it uses data for 1984-88 to describe the general characteristics of labor immigration through the schemes. Finally, by means of a small random sample of applications and issues, it presents details on particular aspects of the immigration. It demonstrates that current labour immigration through the system is selective: most of those entering with long-term permits are highly skilled, well paid, and moving within the internal labor markets of large transnational corporations."

Using data from the 1976 and 1988 censuses, the author notes that the population of Senegal has grown by 37.6 percent over the period and that this growth is concentrated in urban areas. One feature of this trend has been the growing primacy of the capital Dakar and a decline in the relative importance of smaller towns. The need to discourage rural-urban migration by promoting socioeconomic development in rural areas is stressed. (SUMMARY IN ENG) 相似文献

In August 1992, a project team of senior medical and administrative personnel was formed (Housestaff Coverage Project Team) at the Park Ridge Health System, Rochester, N.Y.. The team was given a mandate to address housestaff coverage, primarily from an economic standpoint. Through total quality management (TQM), the project team sought to develop a house coverage plan that was sustainable, efficient, and effective. A plan was developed that includes three layers of service. A minimum "standard hospital coverage" would be available to all physicians and their patients and cover the basic needs of admission, crisis intervention, and issues of length of stay. A complete level of service would be available under the title of "case management" and would consist of total patient management, under the direction of the attending physician, from admission through discharge. The third level of service available to both "standard" and "case managed" patients would be a "consultative service." The latter would function as a traditional in-house medical service and would bill for its services. Park Ridge Hospital believes it has developed a system of housestaff coverage that is sustainable, efficient, and effective. An evaluation mechanism, primarily addressed at length of stay, will tell if we are correct in this assumption. 相似文献

Among the controversies surrounding the provision of health care in a managed care environment is the belief that patients, because they have no particular allegiance to a single physician, are more casual in regard to their keeping appointments. To test this proposition, the authors conducted a study at a California independent practice association, comparing the habits of managed care patients with those of other types of patients. The findings, although based on a limited sample, suggest that managed care patients do indeed have a greater tendency to be appointment no-shows. 相似文献

The frenzy of health care reform activity now led by the Clinton Administration's American Health Security Act of 1993 might end in the worst of all possible outcomes: a new government entitlement program financed by business and a global budget. Unbridled entitlement could drive utilization of benefits to the maximum and, with a budget cap, guarantee rationing. So far, the administration has talked about expanding access and controlling costs--not about the health care product. Given the threat that change poses for vested interests, time will undoubtedly lapse before final implementation of a new system. Unless physicians involved in health management seize the opportunity during this window of opportunity to help shape the future of health care delivery, the likelihood of preserving the U.S. health care delivery system as we know it will be dim indeed. 相似文献

The April 1993 CPS differs from the March 1993 CPS in a number of respects. The April 1993 CPS supplement surveys only workers, whereas the March CPS examines the noncash benefits received by all Americans. The April CPS asks workers about health coverage in the week in which the questions were fielded, whereas the March CPS asks about coverage in the preceding year. In April 1993, there were 112.5 million civilian American workers between the ages of 18 and 64 with jobs. Eighty-two million (73 percent) of them worked for an employer that sponsored a health insurance plan, and 65 million (58 percent of all workers) participated in their employer's health plan. About one-third of workers at firms with fewer than 10 employees had employers who offer health benefits; about one-quarter of all of the workers in these firms participated in their employer's plan. Conversely, 94 percent of workers at firms with more than 1,000 employees had an employer who sponsored health benefits, and over 77 percent of these workers participated in their employer's plan. There are 16.5 million American workers whose employers sponsored health benefits but who did not participate in these benefits. Over one-half of these workers (8.5 million) chose not to be covered. Another 36 percent of these workers (5.9 million) did not participate because they were ineligible or denied coverage. Over 66 percent of the ineligible workers did not participate because they were part-time, contract, or temporary workers. Another 26 percent had not yet completed a probationary period. Among the reasons that those who chose not to participate in their employer's coverage, the vast majority (75 percent) stated they were covered by another health care plan. Twenty-nine percent stated that they chose not to purchase coverage because it was too costly or that they did not need or want the coverage. In 1993, there were 16.7 million workers with no health insurance coverage. The vast majority of these workers (95 percent) were employed by private employers. Sixty-six percent of the workers with no health insurance coverage were self-employed or worked for firms with fewer than 100 employees. 相似文献
