<正> 云南某边检站查获了一车非法偷运的猴子。据说幸亏被查获了,否则将被不法分子卖到南方某市当作一道名菜被人们吃掉。 这事被一个小报记者打听到了,立刻编了一条消息,说这车猴子不论公母全是艾滋病携带者。许多报纸争相转载,反响非同寻常。爱吃猴子的人基本吓得半死,不吃猴子的人对吃猴子的人不但没有表现出起码的同情,还兴灾乐祸。可没过几天,一位有相当责任感的“科学家”专门为猴子作了体检,证实不但没有艾滋病,而且身体比较健康。言下之意:完全符合“食品卫生法”。于是,消息成了谎言,吃猴子的放了心,不吃猴子的白高兴一场。 相似文献

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

Beyond the theoretical basis for integration, three core considerations stand out as the primary reasons for pursuing integration from a physician's perspective. In the authors' experience, the ability to make a case for physician integration stands or falls based on the ability of the integrated delivery system to address these considerations: Gain greater access to capital; develop human resources with talents in managed care and the full spectrum of care services; and sustain an information infrastructure. This article explores the lessons learned in pursuing physician integration. 相似文献

There has been a perceived increase in the number of medical negligence claims in recent years. The modern metropolitan medical examiner is increasingly called upon to deal with numerous medical, legal, social, and ethical issues. Nowhere is the role of the medical examiner more important than in the investigation of deaths related to surgical, diagnostic, anesthetic, or therapeutic procedures. Medical examiners have an important role in the investigative process. Through utilization of the offices and services of the medical examiner, questions raised by families, physicians, and other hospital employees may be satisfactorily answered a priori, and litigation may therefore be averted. 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

城市经济学是经济学中最新和发展最快的学科之一。这门学科的基础,可以追溯到二十世纪二十年代对城市土地经济的研究,在两次世界大战期间,德语系国家对城市问题也进行了大量的研究工作。现代城市经济学与地区经济学有更密切的联系,它在第二次世界大战末期才真正从地区经济学中分离出来。有关城市经济的早 相似文献

产品的出口能力是评价特区、沿海开放地区及区内所设企业外向性能力的重要依据。产品的出口比例是评价产品出口能力的主要指标。所谓产品出口比例是指一定时期内的出口产品占总产品的比重。它既可作为宏观评价指标,也可作为微观评价指标。由于我国对外开放统计工作的历史不长,许多问题的解决办法尚处于探索阶段,因此,实际工作中,关于产品出口比例的计算方法还存在分歧意见。本文就产品出口比例的计算方法作一初步探讨。 相似文献
