Harris M 《Administration in social work》1994,18(2):1-15
Tensions in the relationship between boards and staff are a common feature of voluntary and nonprofit agencies which deliver services. Many of the difficulties reflect lack of clarity about the power of boards. The author describes three models of governance: traditional, membership, and entrepreneurial. Each model has different implications for the power of a board in relation to staff. Practitioners in nonprofit service delivering agencies in the UK have found the models to be a useful tool for explaining the practical difficulties they experience. 相似文献

When physicians, hospitals, and allied health professionals bill for services they render, their information processing requirements are relatively simple, at least compared to those of capitated organizations. When payers (insurers or employers) accept financial risk for the health care services of beneficiaries, they have usually invested in claims processing, membership tracking, and, under managed care, utilization review and provider profiling systems. But payers, for the most part, have not invested in electronic collection of clinical information about beneficiaries, nor have they tended to keep all claims they have processed in electronic form for study after accounts are settled and payments disbursed. In this article, we will explore why informatics is so important to capitated organizations and why payers that have traditionally taken financial risk for insuring the health care costs of populations are also learning about the importance of informatics. 相似文献

"Teacher, what are we going to do next class?" This is an exciting question which I often hear from my students. As an English conversation teacher, I can make the learning of English either a dull and boring duty, or an exciting adventure. It is very important that I make my students hate missing my class, and keep them guessing just what will happen the next time! Let us consider some important ways that any teacher can help his other students want to do their 相似文献

Ugur M 《The International migration review》1995,29(4):964-999
"This article argues that the question of free movement vs. exclusion within the European Union (EU) can be addressed satisfactorily only if we move away from the narrow state-centrism inherent in the current debate. What is required is to 'open' the state concept and examine the implications of state-society relations for EU policy making. Once this is done, it can be seen that the exclusionist stance of the immigration policy and the essentially intergovernmental nature of the policy making are due to an implicit contract between states and constituents implied by the concepts of nationality and citizenship. According to this perspective, the focus on the state or the political elite alone is too one-sided and misses the more complex factors bearing upon EU policy making in this area." 相似文献

Wingen M 《The International migration review》1995,29(3):710-721
"Addressing the question of immigration to Western Europe and especially to Germany from east and southeast Europe and from developing countries of the South, this article considers whether such immigration can compensate for reductions in population in developed countries. It is argued that the demographic deficits of an aging population can only be corrected to a limited extent through immigration. Any solution, in order to be effective, must include a simultaneous increase in the birthrates of Germany and other European Community countries. With particular regard to future social development in Germany and the EC, it would be advisable for governments to effect measures that will provide both for controlled admissions of immigrants from outside the EC and an increase in local reproductive capabilities." 相似文献

An evaluation of population projection errors for census tracts 总被引:1,自引:0,他引:1
"In this article we evaluate the accuracy and bias of projections of total population and population by age group for census tracts in three counties in Florida. We use [U.S. census] data from 1970 and 1980 and several simple extrapolation techniques to produce projections for 1990; we then compare these projections with 1990 census counts and evaluate the differences. For the total sample, we find mean absolute errors of 17%-20% for the three most accurate techniques for projecting total population and find no indication of overall bias. For individual age groups, mean absolute errors range from 20%-29%." This is a revised version of a paper presented at the 1993 Annual Meeting of the Population Association of America. 相似文献

The key to survival in managed care is management of financial risk. You need to know what is in your contract and what you are obligated to do for which population during which period. Information systems can be an enormous help in managing managed care contracts and the financial risks they entail, but poorly selected and configured information systems will do little good for the organization that licenses them. The most important activity of a physician executive who is moving his or her organization into managed care contracting is to lead the process to define the functional requirements for information the organization will need to manage managed care contracts successfully. 相似文献
