This article is a case history of a medium-sized, family-owned business where the corporate planning activity has been taken over by the Executive Board, which is concerned with a careful definition and dissemination of company strategy and with focusing action in the form of long-term planning projects. The organizational learning approach is evolutionary and incremental, involving—as in the Japanese style of management— many levels in project development. 相似文献

This study investigates the relationship of panel accretion to panel attrition and examines its impact on threats to external validity in adolescent substance use research. Panel accretion involves the addition of new participants to a panel design after initial baseline data has been obtained. Accretion occurs in longitudinal studies in which data is routinely gathered on all participants, as is often the case in prevention or epidemiological research on adolescent substance use. Accretion, attrition, and panel findings for three, 2-year panel samples in grades 7 through 9 are examined. The results indicate that accretion and attrition samples have an isomorphic relationship to one another on a range of dependent measures when drawn from the same population. The results are discussed in terms of their implications for adolescent substance use research, the examination of validity threats due to panel bias, and understanding the ecological validity of research findings. 相似文献

"This paper explores the application of a life table approach to the analysis of poverty [in the United States]. After reviewing trends in gender differentials in poverty and mortality, we investigate an indicator of poverty-mortality well-being. The rationale for this approach is that to some extent poverty and mortality are causally interrelated phenomena which are both fundamental to well-being. The empirical results indicate that females are expected to live more years in poverty than are males, but females are expected to live more years in nonpoverty as well. Although the gender differential in poverty rates has increased to the disadvantage of females, and although most of the greater poverty of females cannot be attributed to their greater longevity, the gender differential in poverty-mortality well-being has nonetheless not deteriorated to the disadvantage of women in recent decades." 相似文献

Carbon tetrachloride is a degreasing agent that was used at the Rocky Flats Plant (RFP) in Colorado to clean product components and equipment. The chemical is considered a volatile organic compound and a probable human carcinogen. During the time the plant operated (1953-1989), most of the carbon tetrachloride was released to the atmosphere through building exhaust ducts. A smaller amount was released to the air via evaporation from open-air burn pits and ground-surface discharge points. Airborne releases from the plant were conservatively estimated to be equivalent to the amount of carbon tetrachloride consumed annually by the plant, which was estimated to be between 3.6 and 180 Mg per year. This assumption was supported by calculations that showed that most of the carbon tetrachloride discharged to the ground surface would subsequently be released to the atmosphere. Atmospheric transport of carbon tetrachloride from the plant to the surrounding community was estimated using a Gaussian Puff dispersion model (RATCHET). Time-integrated concentrations were estimated for nine hypothetical but realistic exposure scenarios that considered variation in lifestyle, location, age, and gender. Uncertainty distributions were developed for cancer slope factors and atmospheric dispersion factors. These uncertainties were propagated through to the final risk estimate using Monte Carlo techniques. The geometric mean risk estimates varied from 5.2 x 10(-6) for a hypothetical rancher or laborer working near the RFP to 3.4 x 10(-9) for an infant scenario. The distribution of incremental lifetime cancer incidence risk for the hypothetical rancher was between 1.3 x 10(-6) (5% value) and 2.1 x 10(-5) (95% value). These estimates are similar to or exceed estimated cancer risks posed by releases of radionuclides from the site. 相似文献

This article reports the results of an exploratory study of the organizational characteristics, functions, and roles of intermediary nonprofit organizations selected by the European Union to deliver global grant funding in relation to its Special Support Programme for Peace and Reconciliation in Northern Ireland. The results show that the main factor for determining organizational processes is the need to respond to conflicting pressures from two directions: upward to funding agencies and downward to community groups. This produces contradictory demands that are imported into the organizations as a set of internal tensions. The different structures and capabilities developed by the organizations to maintain unity and integrity in response to these tensions are explored and related to differences in the perceived role of the organizations. 相似文献
