Consider note proposition; it pays off one unit money if proposition is true nothing otherwise. more strongly person believes proposition, higher minimum price would at which sell it. same apply to maximum purchase price. well-known Dutch Book Argument claims that, are ...

These two theories are inter-related as already observed and discussed in many papers (e.g. [DP82,DP88b]). One aspect that is common to the two theories is how to quantitatively measure the degree of conflict (or inconsistency) between pieces of un...

I begin with the question of whether self-locating beliefs can be relevant to beliefs de dicto. Can it ever be rational for an agent to change her degree of belief in a belief de dicto as a result of gaining only self-locating information? To analyze this question, I develop a formal technique for modeling the ideally rational evolution of an agent’s degrees of belief as she learns new informat...

Search in the space of beliefs has been proposed as a convenient framework for tackling planning under uncertainty. Significant improvements have been recently achieved, especially thanks to the use of symbolic model checking techniques such as Binary Decision Diagrams. However, the problem is extremely complex, and the heuristics available so far are unable to provide enough guidance for an in...

OBJECTIVES Grouping patients by self assigned ethnicity may hide intraethnic differences in disease associations and sexual behaviour patterns. The aim of the study was to detect associations between gonorrhoea with differences in ancestry, degree of acculturation, and religious belief in young black Caribbean men, which could subsequently be used to target health promotion interventions.
