Recent research on the self-validation hypothesis suggests that source credibility identiWed after message processing can inXuence the conWdence people have in their own thoughts generated in response to persuasive messages (Briñol, Petty, & Tormala, 2004). The present research explored the implications of this eVect for the possibility that high credibility sources can be associated with more ...

Random fuzzy theory offers an appropriate mechanism to model random fuzzy phenomena, with a random fuzzy variable defined as a function from a credibility space to a collection of random variables. Based on this theory, this paper presents the results of an investigation into the representation of properties of alternating renewal processes that are described by sequences of positive random fuz...

Several credibility models found in published literature have largely been single dimensional in the sense that the observable claims are derived from a single individual risk or a single group of homogeneous risks over a period of time. In the case where the additional dimension of observing different individual risks or different groups of risks are allowed for, the assumption of independence...
