Here’s a short blurb from the website:
The Colloquium continues the series of annual international meetings organized in Prague by the Department of Logic of the Institute of Philosophy. This colloquium will be devoted to philosophical problems related to Dutch Books of all types, including synchronic and diachronic, and their relation to the justification of probability theory as a model of rational opinion.
