Much of the strategic preoccupation of senior managers in the 1990s is focusing on the creation of customer value. Companies are seeking competitive advantage by streamlining the three processes through which they interact with their customers: product creation, order handling and service assurance. 'Micro-strategy' is a term which has been coined for the trade-offs and decisions on where and how to streamline these three processes. The article discusses micro-strategies applied by successful companies.  相似文献

Jane Carmichael's views on Managing Inputs provide a further interesting contribution on a topic, strategic control, that we have covered on several occasions in this column. Carmichael's approach is to dig back behind the results being achieved to the 'inputs' on which they depend. But, while this may unearth causes of performance that can often be missed by a bottom-line orientation, results must ultimately remain vital; a business that is on track with all its input measures, but is missing its output goal is still in trouble. We continue to be interested in hearing from readers with views on strategic control processes, particularly those who have found productive ways of setting input and output targets.  相似文献

Nearly six years after the National Practitioner Data Bank was authorized by Congress in the Health Care Quality Improvement Act of 1986, and more than a year after its actual creation, the device is still only partially operational. What is more, the success of even those limited efforts is being questioned, and the timetable for future developments remains to be firmed up. Also, the costs are much higher than estimated.  相似文献

The day-to-day management of medical practice is so heavily influenced by tactical imperatives that few physicians have the time to think strategically. Traditionally, the difference between tactics and strategy is not a major concern of most physician executives. The realm of tactics is the short run, when managers must make do with the fixed resources at hand. Strategy addresses the long run, when all resources and markets are variable. A tactical focus is understandable, maybe even acceptable, in industries where nothing challenges traditional approaches to production of an established product or service. However, medical care in the 1990s is changing so fast that a physician executive must devote an incredible amount of time and effort just to stay confused about what is going on.  相似文献

"This study compares the fertility patterns of foreign-born and native-born women in Canada and examines whether [the] same set of social characteristics accounts for differential fertility among both the groups. The study also assesses the importance of social characteristics and assimilation on immigrant fertility behavior. Two generations of currently married/cohabiting women with spouse present are analyzed using multiple regressions. The results reveal similar effects on fertility of social characteristics for foreign-born and native-born, while in the case of younger generations the effects are stronger."  相似文献

College newspapers are a powerful but underutilized medium for educating students on health issues, including those related to drug and alcohol use on campus. Editors of these publications are in a position to wield significant influence among their readers. In addition to communicating factual information about the prevalence and impact of substance use among college students, editors can use the press to advocate changes in students' attitudes and behaviors and in college or community policies that affect substance use. A pilot conference was held to help New England college newspaper editors perceive the importance of their role in educating their peers about substance use and other health-related issues, and to offer concrete suggestions as to how they can incorporate these topics into an "activist" campus press.  相似文献

Although the vast majority of deaths occur among terminally ill geriatric patients, little is known about the etiology of these patients' death acknowledgement and ultimate type of treatment. Based on interviews with 76 triads composed of physicians, terminally ill patients, and primary caregivers, this study uses the socialization perspective to identify the actors and actions that most strongly affect the patient's death acknowledgment and receipt of exclusively palliative care (i.e., socialization to the dying role). Whereas patient preferences and sociodemographic characteristics do not influence significantly the patient's odds of death acknowledgment, these odds are increased if their primary caregivers accept death, their physicians are not affiliated with a teaching hospital, and the terminal prognosis is disclosed to them and disclosed "matter-of-factly." Patients who acknowledge death, whose agents value pain alleviation over life-prolongation, and whose physicians are not affiliated with a teaching hospital, are substantially more likely to receive exclusively palliative rather than curative terminal treatment.  相似文献
