Many utility companies offer their customers the choice of participation in an average payment plan, which enables them to pay a fixed sum for their utility bill each month (with final settlement at the end of the billing year), instead of the conventional “pay as you go” billing procedure. Because customers on average payment plans are protected from paying large bills during peak energy-use seasons and because the information about monthly energy use and its cost is perhaps less salient to them, it was hypothesized that customers on the average payment plan would use more electricity than customers not on the plan. Using a nonequivalent control group design, the electricity consumption of a selection of customers of two utility companies (Ns = 475 and 74) was examined. The results showed that there was no evidence to support the hypothesis. Since the logic of hypothesis testing does not permit the ready acceptance of the null hypothesis, several procedural, methodological, and statistical points were made to buttress the conclusion that the average payment plans had no effect on electricity consumption.  相似文献

Participatory approaches are frequently recommended for international development programs, but few have been evaluated. From 2007 to 2010 the Andean Change Alliance evaluated an agricultural research and development approach known as the “Participatory Market Chain Approach” (PMCA). Based on a study of four cases, this paper examines the fidelity of implementation, the factors that influenced implementation and results, and the PMCA change model. We identify three types of deviation from the intervention protocol (lapses, creative adaptations, and true infidelities) and five groups of variables that influenced PMCA implementation and results (attributes of the macro context, the market chain, the key actors, rules in use, and the capacity development strategy). There was insufficient information to test the validity of the PMCA change model, but results were greatest where the PMCA was implemented with highest fidelity. Our analysis suggests that the single most critical component of the PMCA is engagement of market agents – not just farmers – throughout the exercise. We present four lessons for planning and evaluating participatory approaches related to the use of action and change models, the importance of monitoring implementation fidelity, the limits of baseline survey data for outcome evaluation, and the importance of capacity development for implementers.  相似文献

Abstract

This is a report of the second and final stage of a research project evaluating courses for community activists in Israel. We compared 286 graduates of Schools for Community Activists, of whom 198 were still active in their communities and 98 were not, with 138 activists and 131 non-active residents of the same neighbourhoods who had never participated in courses for activists. We noted no significant socio-economic or demographic differences between the graduates and the non-graduates. However, on a range of variables, we found consistent and generally significant differences between the graduate and non-graduate activists: the former reported higher levels of activism, knowledge and skills, higher community involvement and deeper community roots, and assessed more highly the prestige of community involvement. Few differences were noted on their assessment of the benefits and losses of community activity. Since the graduates and non-graduates come from similar backgrounds, we conclude that the courses made a significant contribution to the development and socialization of those activists who participated in them.  相似文献

Latent growth modeling (LGM) has emerged as a flexible analytic technique for modeling change over time because it can describe developmental processes at both the inter- and intra-individual levels. The LGM method can also provide a means for testing the contribution of other variables in order to explain variability in growth trajectories. This paper didactically illustrates the use of LGM as an analytical tool in program evaluation. Specifically, a hypothetical evaluation of a high school drug prevention program was used to demonstrate: (a) how LGM can be used to assess the longitudinal impact of a prevention program by comparing treatment and control populations with respect to individual differences in initial status and in rate of change; and (b) how predictors of initial status (post-intervention) and growth selected on the basis of a particular program theory can be incorporated in the model to explain program impact. Some advantages and limitations of using LGM in program evaluation are highlighted.  相似文献

The ‘new public health’ has stimulated calls to adopt an ecological approach for action aimed at improving population health. However, the implementation of ecological programs has often remained a challenge. The objective of this study was to identify factors facilitating the implementation of ecological tobacco control programming in two Public Health Departments in Québec (Canada) using Scheirer's model of program implementation as a conceptual framework and an exemplary case study design. Analysis revealed two distinct configurations of environmental, organizational and professional characteristics that were related to equally successful implementations of the framework. Key roles for factors such as provincial ministerial guidelines and financial resources, human resources, and relationships and alliances with other organizations, were highlighted. These results replicate findings from quantitative surveys and allow better understanding of the conditions required for planning ecological programming.  相似文献

Despite documented benefits of remanufacturing, many manufacturers have yet to embrace the idea of tapping into remanufactured‐goods markets. In this article, we explore this dichotomy and analyze the effect of remanufacturable product design on market segmentation and product and trade‐in prices by studying a two‐stage profit‐maximization problem in which a price‐setting manufacturer can choose whether or not to open a remanufactured‐goods market for its product. Our results suggest that it is optimal for a manufacturer to design a remanufacturable product when the value‐added from remanufacturing is relatively high but product durability is relatively low and innovation is nominal. In addition, we find that entering a remanufactured‐goods market in and of itself does not necessarily translate into environmental friendliness. On the one hand, the optimal trade‐in program could result in low return and/or remanufacturing rates. On the other hand, a low price for remanufactured products could attract higher demand and thereby potentially result in more damage to the environment. Meanwhile, external restrictions imposed on total greenhouse gas emissions draw criticism in their own right because they risk stifling growth or reducing overall consumer welfare. Given these trade‐offs, we therefore develop and compare several measures of environmental efficiency and conclude that emissions per revenue can serve as the best proxy for emissions as a metric for measuring overall environmental stewardship.  相似文献

This study explored whether religiously affiliated nonprofit schools participating in Milwaukee's long‐standing school voucher program engage in more fundraising and perform better on academic indicators than nonsectarian nonprofit schools. The analysis of three years of organizational‐level voucher school data reveals that a higher percentage of religious affiliated schools engage in fundraising, and that religious schools affiliated with umbrella organizations have higher test score indicators than nonsectarian schools. The author concludes that the religious advantage is likely in part a result of the broader access to networks and resources available to religious schools associated with umbrella organizations like a Catholic archdiocese or Lutheran synod. The results are relevant to policymakers who are considering implementing a reinvented government approach to the provision of public goods, as well as leaders of nonprofit corporations who seek to maximize performance.  相似文献

Numerous professional fields have an increasing need for individuals trained in statistics and other quantitative analysis techniques. Today there exists great potential to fulfill this need by providing opportunities through online learning. However, to provide a high-quality education for returning adult professionals seeking advanced degrees in applied statistics online, many challenges need to be overcome. Based on our experience developing Penn State University’s online program in applied statistics, we discuss the evolution of the program’s curriculum, recruitment and development of online faculty, and meeting the requirements of students as important areas that require consideration in the development of an online program. We also highlight program evaluation strategies employed to ensure innovation and improvement in online education as cornerstones to a program’s success.  相似文献
