The credibility of an instructional simulation is the most important issue in distance education, where it may replace hands-on activities. This credibility is based in large part upon verisimilitude, a perception strongly influenced by the simulation’s realism. This paper presents a case study encompassing the design process of a simulation-based virtual laboratory, which was guided by a reali...

Characteristics of persuasive message sources have been extensively studied. However, little attention has been paid to situations when people are motivated to form an evaluation of the communicator rather than the communicated issue. We postulated that these different foci can affect how a source validates message-related cognitions. Participants focused on the source (Studies 1 and 2) or the ...

As in New Classical models. credihiltty is imperfect: the monetary authorrty may not complete a promised disinflation.

We introduce a class of Bayesian infinite mixture models first introduced by Lo (1984) to determine the credibility premium for a non-homogeneous insurance portfolio. The Bayesian infinite mixture models provide us with much flexibility in the specification of the claim distribution. We employ the sampling scheme based on a weighted Chinese restaurant process introduced in Lo et al. (1996) to e...
