Electric utility planners and wind energy researchers pose a common question: What is the capacity value of a wind plant? Tentative answers, which can be phrased in a variety of ways, are based on widely varying definitions and methods of calculation. From the utility's point of view, a resource that has no capacity value also has a reduced economic value. Utility planners must be able to quant...

A multiattribute utility approach is adopted to assess the value of an information system. Various economic analyses of the value of information are reviewed and the conceptual problems regarding the definition of this value and some measurement difficulties are discussed. A list of possible utility attributes is proposed for a reporting system value assessment, and for each attribute a measure...

Driven by the increasing demand, grid technology is entering the business market in form of utility computing, grid middleware and grid-enabled application. However, the business market is interested in complete grid solutions. This means that for a successful take up of grid technology on the business market the establishment of grid value networks is required. This again can only be achieved ...

The utility value was compared among 3 surgical interventions, and the validity of the time trade-off (TTO) method was evaluated by analyzing the correlations of the utility value with the results of the Visual Function Questionnaire-14 (VF-14) and other variables. The subjects were 127 patients aged 40-85 years who were surgically treated between January 2008 and March 2010, including 26 patie...

Utility value is associated with positive learning outcomes in science and is often used to motivate engagement in the sciences, but less is known about what influences its development and maintenance, particularly during the critical middle school years. Using multinomial regression applied to longitudinal data from approximately 2600 middle-school students, we test the relationship of science...

In the context of decision under uncertainty, standard gambles are classically used to elicit a utility function on a set X of consequences. The utility of an element x in X is derived from the probability p for which a gamble giving the best outcome in X with probability p and the worst outcome in X otherwise, is indifferent to getting x for sure. In many situations, uncertainty that can be ob...

This article examines within-culture variance in the influence of values on perceptions and use of information technology (IT). Based on cross-cultural research, we suggest that cultural values influence technology acceptance and use. Specifically, we argue that masculinity/femininity and individualism/collectivism directly influence personal innovativeness with IT, computer anxiety, and comput...

We consider the problem of designing perhaps massively distributed collectives of computational processes to maximize a provided world utility function We consider this problem when the behavior of each process in the collective can be cast as striving to maximize its own payo utility function For such cases the central design issue is how to initialize update those payo utility functions of th...
