Many early sociologists, particularly in Chicago and both inside and outside of the academy, focused on the relation between
human society, social justice, and the natural environment. Caroline Bartlett Crane (1858-1935), applied sociologist and noted
Progressive Era reformer, was an eminent figure in this work. She linked healthy individuals and social justice to a robust
and balanced environment. In addition to her national leadership in municipal sanitation, Crane labored to protect the natural
environment from the rapid degradation caused by increased industrialization, population growth, and changes in land use and
exploitation during the Progressive Era. As one of the forerunners of the ecology and ecofeminism movements of today, Crane
is part of women’s hidden heritage and her life exemplifies the theory of “ecofeminist pragmatism.” 相似文献

Investigators who manage multicenter clinical trials need to pay careful attention to patterns of subject accrual, and the prediction of activation time for pending centers is potentially crucial for subject accrual prediction. We propose a Bayesian hierarchical model to predict subject accrual for multicenter clinical trials in which center activation times vary. We define center activation time as the time at which a center can begin enrolling patients in the trial. The difference in activation times between centers is assumed to follow an exponential distribution, and the model of subject accrual integrates prior information for the study with actual enrollment progress. We apply our proposed Bayesian multicenter accrual model to two multicenter clinical studies. The first is the PAIN‐CONTRoLS study, a multicenter clinical trial with a goal of activating 40 centers and enrolling 400 patients within 104 weeks. The second is the HOBIT trial, a multicenter clinical trial with a goal of activating 14 centers and enrolling 200 subjects within 36 months. In summary, the Bayesian multicenter accrual model provides a prediction of subject accrual while accounting for both center‐ and individual patient‐level variation. 相似文献

In the area of planning, the literature has been almost entirely concerned with planning in the business (i.e. profit) setting. Some literature does exist on planning in the nonprofit sector, but it usually deals with tactical planning of the short-term character. This is specially true in the area of libraries and many librarians have developed and do administer large, complex organization— where conprehensive, long range planning is almost completely untreated in the literature.The current paper discusses the various steps in the strategic planning process, and relates them to a situation in which comprehensive long range plans for a new health sciences library have been developed, and to a considerable degree, implemented. In this framework, the steps of developing purpose and objecives, forecasting and policy formulation, developing and choosing growth strategy, determining resource requirements and provions, developing an organizational structure, and control system utilization are discussed both in the general framework of comprehensive planning, and with respect to actual experience in the development of a health sciences library. The roles of tactical planning and the implementation of plans are also treated. 相似文献

Assessing Adjustment to Aging: A Validation Study for the Adjustment to Aging Scale (AtAS) 总被引:1,自引:0,他引:1

Adjustment to aging (AtA) is a multifactor adjustment process with implications on aging well among older adults. The aim of this study was to develop and validate a scale to assess the factors that older adults recognized as indicators of their AtA, with a cross-national comparative perspective towards aging well. Convenience sampling was used to gather questionnaire data, including demographics and the proposed scale. Complete data was available for 1,291 older community-dwelling adults, aged between 75 and 102 years (M = 83.9; SD = 6.68), who represented four different nationalities. Exploratory and confirmatory factor analyses were performed for dimension reduction and exploration of the factorial structure. Data gathered with the 22-items AtA five-factor scale showed overall good psychometric properties (in terms of distributional properties, statistical significant factor weights, factorial, convergent, discriminant criterion and external-related validities, as well as reliability). Five factors were selected for the Adjustment to Aging Scale: (a) sense of purpose and ambitions (b) zest and spirituality; (c) body and health; (d) aging in place and stability; and (e) social support. We present a 22-item scale with five factors for AtA estimation in a cross-national elderly population which produced valid and reliable data for elder persons from four different nationalities. Results showed that this scale is an adequate cross-cultural instrument for research, clinical practice and program development in the health care context. These may benefit from clearly understanding AtA as an important component for reducing health disparities and for aging well, across nationalities. 相似文献

The Delta method uses truncated Lagrange expansions of statistics to obtain approximations to their distributions. In this paper, we consider statistics Y=g(μ+X), where X is any random vector. We obtain domains 𝒟 such that, when μ∈𝒟, we may apply the distribution derived from the Delta method. Namely, we will consider an application on the normal case to illustrate our approach. 相似文献

AbstractWe use chi-squared and related pivot variables to induce probability measures for model parameters, obtaining some results that will be useful on the induced densities. As illustration we considered mixed models with balanced cross nesting and used the algebraic structure to derive confidence intervals for the variance components. A numerical application is presented. 相似文献

Abstract There are few empirical tests of the relationship between local resource production and community social systems. This paper reports the results of research on two communities in northern Idaho: one timber-dependent, the other mining-dependent. Data were collected for 13 indicators of resource production and 15 indicators of social change for periods up to 65 years. Regression analysis was used to test if community social change is associated with the production level of local resource systems. The final models support the hypothesis in both communities. The form, lag condition, and strength of the relationship is complex and may vary with the dependent indicator. The original causal image—the rural community with a social order that directly responds to changes in local resource production—is blurred. Suggestions are made for future research. 相似文献

Chloroform Exposure and the Health Risk Associated with Multiple Uses of Chlorinated Tap Water 总被引:9,自引:0,他引:9
Recently, showers have been suspected to be an important source of indoor exposure to volatile organic compounds (VOC). The chloroform dose to an individual from showering was determined based on exhaled breath analysis. The postexposure chloroform breath concentration ranged from 6.0-21 micrograms/m3, while all corresponding background breath concentrations were less than 0.86 micrograms/m3. The internal dose from showering (inhalation plus dermal) was comparable to estimates of the dose from daily water ingestion. The risk associated with a single, 10-min shower was estimated to be 1.22 x 10(-4), while the estimated risk from daily ingestion of tap water ranged from 0.130 x 10(-4) to 1.80 x 10(-4) for 0.15 and 2.0 L, respectively. Since the estimates of chloroform risk from domestic water use for the three exposure routes--ingestion, inhalation, and dermal--are similar, all routes must be used to calculate the total risk when making policy decisions regarding the quality of the municipal water supply. 相似文献
