This article examines the current trends of proliferation of commercial gaming, especially in the United States, in the context of the third wave of legalization of gambling that has been experienced since the founding of the nation. The author looks at the historic foundations of the spread of casino-style gambling, and notes the types of casino gaming that have led the way in the current expansion. He also points out why it is reasonable to expect that this wave too may come crashing down, as general acceptance of wide-spread casino gaming in America may indeed be short-lived.Gambling and the Law® is a registered trademark of I.

Business success in the 21st century will be based on the widespread mastery of leadership roles, rather than on the directives of a professional or leadership elite. The first step for systematically enacting a leadership development agenda for our nation is to identify the factors, values or qualities most important to leadership effectiveness. Next, we must improve our understanding of how these guiding ideas and insights translate into what successful leaders do. As we perfect this understanding, we will need to operationally define the best practices of successful leaders. These best practices must then become benchmarks for intensive leadership development efforts.This article considers nine methodological challenges of the first agenda item-identification of the factors, values or qualities most important to leadership effectiveness. To illustrate these challenges, the authors use their own business leadership research as a case study. This research surveys 127 chairmen, chief executive officers, and presidents-a cross section of successful U.S.A. business leaders, including men and women from all parts of the nation who have diverse industry, racial, ethnic and religious backgrounds. The authors identify where methodological improvements are needed to cope with the challenges of leadership research. They suggest important directions for methodological development and propose three minimum standards for future leadership research.  相似文献

All over the country, millions of research dollars are being spent to devise an effective way of measuring quality that could be standardized in health care, and hospitals and managed care companies are experimenting with a variety of quality tools, trying to document what they now can only perceive as improvement. Experts are divided on what works best, but all applaud and embrace the efforts. In this special report, several of them discuss their views on what works, and what doesn't work, in the exploding field of health care quality measurement.  相似文献

There is much truth in the adage that "the more things change, the more they stay the same." Nowhere does this seem more apparent than in health care where, amidst monumental reconfiguration, basic foundations of physician-patient relationships and attention to the impact of psychosocial factors on health and health care delivery remain as critical influences. While the importance of the therapeutic relationship and the influence of psychosocial factors in medical care has been clear in traditional systems of delivery, these factors may be even more critical in managed care systems. These emphases must be incorporated by design, however, and not left to default.  相似文献

This paper introduces a drawing technique developed by the author for use in the assessment and treatment of individuals and families. The client is invited to draw a floor plan of his or her home or apartment, or an aerial view of un outdoor area. The drawing is then discussed and considered as a means of understanding critical elements of the experience of life space. The material derived is discussed from the eerspectives of family systems, psychodynamic, and abuse treatment theories, with special reference to notions of family structure, boundary, the self, and memory. Emphasis is placed on the actual physical layout of the home, as well as the subjective experience of it. Applications of the drawing technique for exploring memories are illustrated. Case examples are presented from clinical trials with children and adults in residential treatment, inpatient, and outpatient settings.The Heller Financial Corporation generously supports the development of household and spatial drawings for treatment and prevention. A version of this paper was presented at the 43rd Annual Meeting of the American Association of Psychiatric Services for Children, New Orleans, February 26, 1992. The author wishes to thank Robert B. Bloom, Ph.D., Excutive Director of JCB, for supporting the development of ideas and techniques discribed in this paper.  相似文献

"This article evaluates the consequences of international migration since World War II, with particular reference to Great Britain. It emphasizes the substantial differences between the origins and responses to immigration in the United Kingdom and that of the rest of Western Europe." It is found that "people of non-European origin from Commonwealth countries have predominated in postwar immigration to the United Kingdom. That migration neutralized the previously dominant pattern of emigration and increased U.K. population by about 3 million people through immigration and higher fertility, with only slight effects upon the age distribution."  相似文献

Current developments in the sociotechnical framework address a number of vital issues that failed to occupy the high ground in its formative years. These include: (i) the purpose of the systems, to create customer value under social and resource constraints, (ii) the context or external business environment, and (iii) the dynamics of the sociotechnical system. Due attention to the dominant issues of purpose, context, and their dynamics make it more meaningful to speak of sociotechnical business systems (STBS) and organizational learning instead of sociotechnical systems (STS) and individual learning. In STBS each unit in an organization has business responsibilities and goal-based couplings with its environment and focuses on the creation of customer value. The implications of this shift from STS to STBS are discussed and illustrated with current research and two summary case studies.  相似文献

Data collected before the routine application of prenatal screening are of unique value in estimating the natural live-birth prevalence of Down syndrome. However, much of these data are from births from over 20 years ago and they are of uncertain quality. In particular, they are subject to varying degrees of underascertainment. Published approaches have used ad hoc corrections to deal with this problem or have been restricted to data sets in which ascertainment is assumed to be complete. In this paper we adopt a Bayesian approach to modelling ascertainment and live-birth prevalence. We consider three prior specifications concerning ascertainment and compare predicted maternal-age-specific prevalence under these three different prior specifications. The computations are carried out by using Markov chain Monte Carlo methods in which model parameters and missing data are sampled.  相似文献
