In this paper, we elaborate on our earlier work on modelling the mental states of PRS-like agents by considering the logical properties of intentions and various rationality postulates for PRS-like agents that are a consequence of this modelling, in particular Bratman’s asymmetry thesis, the side effect problem for intentions and Rao and Georgeff’s nontransference principles. We show that PRS-l...

In this paper we consider the dynamics of abstract argumentation in Baroni and Giacomin’s framework for the evaluation of extension based argumentation semantics. Following Baroni and Giacomin, we do not consider individual approaches, but we define general principles or postulates that individual approaches may satisfy. In particular, we define abstraction principles for the attack relation, a...

In the first part of the article, the author presents elementary postulates of the working model in teenage therapeutic groups in the Neurosis and Eating Disorders Treatment Centre "Dabrówka", in the year...

A minimal approach to modelling belief change is presented, wherein arguably all successful belief change operators are captured. Two assumptions are made: that a notion of similarity between knowledge bases underlies revision, and that the belief change operator being modelled is successful, in that if a knowledge base K is revised by a sentence then will be in the revised knowledge base. The ...
