Organizational innovation is now widely seen tobe a major source of competitive advantage for firms,along with product and process innovation. One of themajor intellectual sources for the upheavals, in which firms strive for some formof international best practice, is thesociotechnical systems tradition, which traces its rootsback to innovations such as semi-autonomous work teamsin manufacturing in the 1960s, associated with the work of theTavistock Institute. An international Colloquium wasstaged in Melbourne, Australia, in May 1995, to explorethe current relevance and contributs to organizational innovation. 相似文献

A measure of range of ability is used to profile the 85-years-old-and-older (oldest old) population, including the highly disabled institutional population. This new measure uses two new questions available in the 1990 Decennial Census concerning a self-care limitation and a mobility limitation as well as the usual question concerning a work limitation. In addition to examining the extent of disability among the oldest old, the article examines the extent of care potentially available in the household as well as the economic characteristics of this age group. It is also profiled in terms of relevant personal characteristics, including age, gender, marital status, race, ethnicity, rural residence, education, and employment. A key question addressed is the need for help or care among the oldest old and how various long-term care proposals would meet such needs. A careful analysis of this unique and growing population is necessary to both allay fears of the cost of care or help as well as to dispel stereotypes of this age group as frail and dependent, and in need of institutional care. 相似文献

This study contrasted the experienced quality of life of residents living on one of two nursing home units: a unit for those considered socially intact and a unit combining residents who had moderately impaired cognition or physical function with those requiring skilled nursing or therapy. Qualitative interviews were held with residents of both units. The findings indicate that the social environment of each of the units played a fundamental role in the residents' quality of life. The social environment affected the residents' conceptions of self, their interactions with other residents and their interactions with the nursing staff. The article suggests the processes behind the social environment of each floor that may have resulted in different perceptions of the quality of life. 相似文献

"Designed in 1919-20 by the British mediator Lord Curzon as an armistice proposal between the then warring powers Poland and Soviet Russia, the Curzon Line served to identify the maximum territorial reach of Soviet political influence in Europe....[The author discusses] a program of resettlement which would target communities on both sides of the new border, a policy eventually affecting some 1.4 million individuals...." The implementation and impact of this population exchange are described. 相似文献

Worldviews or Social Groups as the Source of Moral Value Attitudes: Implications for the Culture Wars Thesis 总被引:1,自引:0,他引:1
Individual moral value attitudes are typically explained by reference to social experiences as indicated by social group variables. Contrary to this view, the emergent culture wars perspective claims that two worldviews that transcend social groups are ultimately and fundamentally responsible for moral value attitudes. Although this relationship has been claimed for the general population, it has not been investigated with national representative data. This paper contrasts the worldview and social group explanations by examining the relative importance of the worldviews implicated in the culture wars literature and the social groups found to be important in previous research. I find social groups to be more important than worldviews, but that worldviews also have explanatory power. I conclude with a discussion about possible clarifications of the culture wars thesis. 相似文献

"While a generalized utility maximization approach to migration decisionmaking is not innovative, the principal extensions of this paper involve the search for an instrument capable of measuring changes in utility levels consistent with all preferences (i.e., with all forms of utility functions), requiring only data on observed behaviour. Our approach is to construct a Location-Specific Utility Index (LSUI), whose component variables serve as proxies for the arguments in [U.S.] households' utility functions.... The testable hypothesis is formulated as follows: Assuming constant household preferences and expansion of the household's feasible set over time, the household's utility level is greater following the migration decision.... The results are compared with the households' migration decisions. The empirical evidence shows that migration may reasonably be modelled as a consumption activity by households to maximize utility."

The Community Prevention Trial was 5-year effort to reduce alcohol-involved injuries and death through a comprehensive program of community awareness and policy activities. The three experimental communities were of approximately 100,000 population each (one in Northern California, one in Southern California, and one in South Carolina). Matched comparison communities were used for each experimental community. This article describes the evaluation approach used in a program that sought to change environmental factors not a specific population or target group. This approach demanded unique evaluation approaches for determining overall community aggregate effects, that is, distal outcomes, as well as changes in key mediating variables, that is, process effects. The problem of trending and lagged effects of community prevention programs are discussed. 相似文献

Theory and research have not kept pace with the growing interest in evaluating quality of mental health care, resulting in the use of unvalidated quality indicators. A framework for validating quality indicators is offered by which quality is viewed as the relationship between service structures, processes, and outcomes. Adoption of this framework will facilitate the measurement of quality using valid indicators and should be useful to agencies in their continuous quality improvement efforts. Valid information about the quality of mental health care services will help purchasers and consumers make more informed health care decisions. 相似文献
