Two studies considered the interplay between user-perceived usability (i.e., pragmatic attributes), hedonic attributes (e.g., stimulation, identification), goodness (i.e., satisfaction), and beauty of 4 different MP3-player skins. As long as beauty and goodness stress the subjective valuation of a product, both were related to each other. However, the nature of goodness and beauty was found to ...

This paper develops an approach to testing the adequacy of both classical and Bayesian models given sample data. An important feature of the approach is that we are able to test the practical scientiic hypothesis of whether the true underlying model is close to some hypothesized model. The notion of closeness is based on measurement precision and requires the introduction of a metric for which ...

This paper describes a new algorithm, called MDQL, for the solution of multiple objective optimization problems. MDQL is based on a new distributed Q-learning algorithm, called DQL, which is also introduced in this paper. In DQL a family of independent agents, exploring diierent options, nds a common policy in a common environment. Information about action goodness is transmitted using traces o...

This paper describes the deployment of Plone, an Open-Source content management system, to support the activities of CALIBRE, an EU-funded coordination action integrating research into Libre software. The criteria by which Plone was selected are described, and the goodness of fit to these criteria is analysed. As a coordination action, CALIBRE involves 12 partners with different requirements an...

Do people with different kinds of bodies think differently? According to the body-specificity hypothesis (Casasanto 2009), they should. In this paper, I review evidence that rightand left-handers, who perform actions in systematically different ways, use correspondingly different areas of the brain for imagining actions and representing the meanings of action verbs. Beyond the concrete domain o...

Some assert that it is impossible to test preference restrictions against revealed preference. The “goodness” preference restriction simply assumes that one value of a nonmarket good is preferred over another other with any fixed commodity consumption. This paper uses a preference-theoretic methodology to show how goodness can be falsified by revealed preference for compensation-based welfare a...

The influence of sample size on informetric characteristics is examined to determine whether theoretical mathematical models can adequately fit large data sets. Two large data sets of queries submitted to the Excite search service were sampled for search characteristics (term frequencies, terms used per query, pages viewed per query, queries submitted per session) producing data sets of various...
