Should physicians really be polishing up their CVs or preparing to enter another line of work? In a word: No. What a recent survey makes clear is that, while managed care is driving physicians from some markets, jobs are still available in other markets traditionally underserved by physicians. This is not to suggest that the physician employment market has gone unchanged. Many physicians, particularly specialists, have taken income hits, and some specialists truly are in need of work. Primary care physicians, however, have seen their stars rise and are now in a position to work wherever they want. Physicians may no longer be able to practice within 50 miles of where they were raised or where they were trained, as has been their wont. Instead, they will have to do what other professionals have long done--go where job opportunities take them. In short, they will have to add a career strategy to their scientific mindset, and that means an aggressive job search, coupled with a strong consumer orientation.  相似文献

This article discusses the current status of research regarding the assessment of attitudes toward euthanasia and other right to die constructs with a focus on conceptual and methodological issues hindering advancement in this area. Two models are presented: a conceptual model for differentiating the various right to die constructs, and a measurement model to guide scale development and refinement. The conceptual model defines the right to die constructs as a function of locus of decision and locus of action. Health status and age are hypothesized as important factors that in some instances are defining attributes in right to die constructs and in other instances are factors influencing people's attitudes toward the right to die. The measurement model considers the importance of construct specificity, individual characteristics, and conviction in the assessment of right to die attributes. An extant euthanasia attitude scale is presented and evaluated in terms of the models to demonstrate how they may be useful for advancing attitude research in this important area.  相似文献

This study examines the impact of mandatory seat belt laws on fatal and incapacitating injury rates in the states. Annual data for all 50 states for the period 1975-1991 are used. Pooled time series analysis is employed. The general conclusion that emerges from this analysis is that seat belt laws significantly impact state fatal injury rates. Primary enforcement and all-seat coverage provisions appear to be particularly effective in reducing fatality rates.  相似文献

Sensitive research issues call for anonymous questionnaires. This makes accurately matching pretests with posttests difficult or impossible. Various subject-generated coding schemes have been developed, but their accuracy has been unknown. This anonymous study, with 745 students, used subject-generated coding to match pretests with posttests. The matching was verified for accuracy with the use of a collateral, anonymous, sticker identification system. The coding system was able to accurately match 75.2% of all the pretest-posttest pairs. An additional 22.1% of the pairs were left unmatched and only 2.7% were matched incorrectly. Subject-generated coding systems can be very effective where confidentiality is important to protect.  相似文献

The way the nation provides for the financing and delivery of long-term care is badly in need of reform. The principal options for change are private insurance, altering Medicaid, and public long-term care insurance. This article uses the Brookings-ICF Long-Term Care Financing Model to evaluate each of these options in terms of affordability, distribution of benefits, and ability to reduce catastrophic out-of-pocket costs. So long as private insurance is aimed at the elderly, its market penetration and ability to finance long-term care will remain severely limited. Affordability is a major problem. Selling to younger persons could solve the affordability problem, but marketing is extremely difficult. Liberalizing Medicaid could help solve the problems of long-term care, but there is little public support for means-tested programs. Finally, universalistic public insurance programs do well in meeting the goals of long-term care reform, but all social insurance programs are expensive and seem politically infeasible in the current political environment.  相似文献

Coming out     
Self-knowledge is the beginning of integrity, of coming out of the closet, and is a prerequisite for dealing well with change. Integrity is not just about not lying. Integrity means as on the inside, so on the outside. The Latin roots of integrity refer to touch. To have integrity is to be untouched, undivided, whole, integrated, integral. There is a tight relationship between integrity and the ability to change, because integrity is about knowing yourself, about being transparent. Integrity allows you to move with tremendous speed when the time comes to move. An organization that wants to learn to dance with change must come to know itself and its environment thoroughly. To do this, it must make use of all the knowledge of every member--and all of their learning capability. It must be built into the culture that new information and different points of view are powerful, are welcomed.  相似文献
