Eric Hirst Linda Berry Kim-Elaine Johnson Richard Tepel John Trimble Benson Bronfman Stephen Wright 《Evaluation and program planning》1983,6(2):103-113
This paper summarizes a detailed plan for evaluation of the residential energy conservation programs offered by the Bonneville Power Administration (BPA). The major purpose of the evaluation is to determine the energy savings attributable to the programs and to identify differences between program participants and nonparticipants. The focus of this paper is on the sampling issues associated with reliable estimates of energy savings. The methodology attempts to correct for the self-selection bias likely to occur in conservation program evaluation by using intentional nonrandom sampling. In addition, the paper suggests a variety of analytical approaches to analyzing the data with respect to energy savings.The proposed design, using four different groups to estimate program effects, is a comprehensive endeavor. This is appropriate for BPA because of the substantial investment it is making in conservation. However, the design is flexible and allows for use offewer groups to reduce evaluation costs. 相似文献

Wright GF 《Physician executive》1995,21(6):21-24
This article is one physician's account of his experiences in managing a large multispecialty group practice. While he was able to accomplish much in his tenure during the latter half of the 1980s, it was, on balance, a negative experience. He describes both the high and the low points of the period and assesses how both contributed to his eventual downfall. While personal, the account has important implications for others involved in the rapidly changing, personally rewarding, and eminently challenging health car system in which physician executives work. 相似文献

The term “intercurrent events” has recently been used to describe events in clinical trials that may complicate the definition and calculation of the treatment effect estimand. This paper focuses on the use of an attributable estimand to address intercurrent events. Those events that are considered to be adversely related to randomized treatment (eg, discontinuation due to adverse events or lack of efficacy) are considered attributable and handled with a composite estimand strategy, while a hypothetical estimand strategy is used for intercurrent events not considered to be related to randomized treatment (eg, unrelated adverse events). We explore several options for how to implement this approach and compare them to hypothetical “efficacy” and treatment policy estimand strategies through a series of simulation studies whose design is inspired by recent trials in chronic obstructive pulmonary disease (COPD), and we illustrate through an analysis of a recently completed COPD trial. 相似文献

Defining and measuring patient satisfaction with medical care 总被引:19,自引:0,他引:19
This paper describes the development of Form II of the Patient Satisfaction Questionnaire (PSQ), a self-administered survey instrument designed for use in general population studies. The PSQ contains 55 Likert-type items that measure attitudes toward the more salient characteristics of doctors and medical care services (technical and interpersonal skills of providers, waiting time for appointments, office waits, emergency care, costs of care, insurance coverage, availability of hospitals, and other resources) and satisfaction with care in general. Scales are balanced to control for acquiescent response set. Scoring rules for 18 multi-item subscales and eight global scales were standardized following replication of item analyses in four field tests. Internal-consistency and test-retest estimates indicate satisfactory reliability for studies involving group comparisons. The PSQ well represents the content of characteristics of providers and services described most often in the literature and in response to open-ended questions. Empirical tests of validity have also produced generally favorable results. 相似文献

R.W. Wright 《Long Range Planning》1976,9(1):12-19
The emphasis of this article is on the need to pay greater attention to the longer-term. It deals particularly with the potential problems and opportunities surrounding the supply of key raw materials. A key question is the potential availability of certain new materials given what are now effectively uneconomic prices to the producer. The author argues for much closer liaison and involvement of Europe organizations in mining (e.g.) and points to some areas of considerable potential. 相似文献

This article examines the performativity of intellectual property in digital gaming environments, with a focus on Massively Multi-Player On Line Games (MMOGs). The analysis centers on the creation and management of goodwill, an intangible asset of considerable value to corporations based on affective bonds between consumers, corporations, and their commodities in the marketplace. Most critical analyses of intellectual property consider neither the centrality of goodwill to corporate management of their intellectual properties in digital environments, nor the significance of the legal conditions that structure activity in such contexts. We develop a theoretical framework based on cultures of circulation involving network sociality, circuits of interactivity and the extensibility of the computer/user interface. This enables us to better understand shifting relations of power and reciprocity between corporations and consumers in digital gaming contexts, where the division between player-consumption and player-production is increasingly blurred. Technological capacities for consumers to become producers of gaming content changes the terrain upon which conflicts between corporations and consumers about intellectual property are negotiated and enhances the value of goodwill. An examination of Linden Lab's Second Life – one of the fastest growing MMOGs and the first to affirm players’ intellectual property rights in their digital creations – provides an illustration of both the limits and possibilities afforded by goodwill as a form of emerging governance in game worlds. 相似文献

Local economic institutions (systems of property rights and rules of land use) influenced the course of economic change in European history, as well as state formation and religious change. In this paper, I outline the theoretical implications of these regional effects. None of our existing macrolevel theories and explanations of the "rise of the West" can adequately incorporate them, so I present an alternative theory, based on rational choice premises. Yet the existence of these regional effects also highlights the deficiencies of a rational choice theoretical approach. First, the approach is unable to explain historical contexts, institutional legacies, or the effects of timing, which were vital for outcomes of social change but that lie outside the model itself. Second, although it can be very useful, the model of the actor motivated by material self-interest often proved inadequate in historical situations. Solutions are suggested. 相似文献
