Objective: To discuss the potential of a café on the premises of an aged-care facility as a vehicle for culture change. Method: Secondary analysis of primary qualitative data that explored the value of a café in an aged-care facility, compared with culture-change principles established from a literature review. Results: Secondary analysis established congruence between culture-change principles and the themes established in the primary qualitative data. A café, in one aged-care facility, has facilitated the following dimensions of culture change for residents: individualized care, facilitation of meaningful relationships, opportunities for participation in life roles, and creation of a sense of belonging. Conclusion: Culture change can be achieved through environmental innovations, such as a café, where food and dining maximize social opportunities and create a homelike environment that facilitates continuation of residents' identity. 相似文献

Inappropriately high weight in children is a persistent problem in the United States, and physical activity is often reduced in schools due to academic demands. Effective after-school programs could positively impact both physical activity and overweight/obesity, however previous reviews and meta-analyses have indicated minimal effects. Both 4- and 3-day/week versions of a social cognitive theory-driven physical activity/nutrition after-school program were evaluated against unstructured care to assess effects in children (overall Mage = 10.00 years, SD = .80). For changes over 9 months in body mass index (BMI), effects sizes (Cohen’s d) were .68, .40, and .07 in the 4-day (n = 70), 3-day (n = 70), and unstructured (n = 50) groups, respectively. Similar patterns of effects were found for changes in free-time physical activity and cardiovascular endurance. Incorporating a theory-based prediction model previously supported in teens through older adults, with and without medical disorders and health-risk factors, improvements in exercise-related self-regulation and self-efficacy, and mood, significantly predicted increased free-time physical activity (R2 = .48). Effects significantly strengthened to R2 = .62 when completion/non-completion of the recommended 300 min/week of physical activity was also accounted for. Change in BMI was inversely related to physical activity change, β=-.14, p < .05. The present evaluation process indicated promising effects, and indicated theory-based targets to foster future program improvements. 相似文献

The two-group discriminant problem has applications in many areas, for example, differentiating between good credit risks and poor ones, between promising new firms and those likely to fail, or between patients with strong prospects for recovery and those highly at risk. To expand our tools for dealing with such problems, we propose a class of nonpara-metric discriminant procedures based on linear programming (LP). Although these procedures have attracted considerable attention recently, only a limited number of computational studies have examined the relative merits of alternative formulations. In this paper we provide a detailed study of three contrasting formulations for the two-group problem. The experimental design provides a variety of test conditions involving both normal and nonnormal populations. Our results establish the LP model which seeks to minimize the sum of deviations beyond the two-group boundary as a promising alternative to more conventional linear discriminant techniques. 相似文献

Recent advances in statistical estimation theory have resulted in the development of new procedures, called robust methods, that can be used to estimate the coefficients of a regression model. Because such methods take into account the impact of discrepant data points during the initial estimation process, they offer a number of advantages over ordinary least squares and other analytical procedures (such as the analysis of outliers or regression diagnostics). This paper describes the robust method of analysis and illustrates its potential usefulness by applying the technique to two data sets. The first application uses artificial data; the second uses a data set analyzed previously by Tufte [15] and, more recently, by Chatterjee and Wiseman [6]. 相似文献

Decision support for managers and policy makers, such as required in planning and evaluation efforts, often requires ad hoc behavioral modeling to account for context-specific phenomena and to handle data limitations. This paper introduces a systematic approach useful for meeting these requirements in which time-varying parameter estimation plays an important role. A case study evaluating the impacts of public policy actions on residential natural gas conservation illustrates the approach. 相似文献

Environmental scanning activities of over 400 top management subunits in 108 European manufacturing firms provided the data base for this research. Four traits (constructs) of scanning using three methods (interest, frequency, and time) were examined. A confirmatory factor analysis approach to multitrait-multimethod (MTMM) data was employed. Verification of the reliability as well as convergent and discriminant validity of the scanning scales are reported and discussed. The viability of confirmatory factor analysis in providing a precise analysis of partitioning variance according to trait, method, and error is demonstrated. 相似文献
