This thesis focusses on the question how compositional language emerged. Two new models for combinatorial message use are presented. In these models two agents play a Lewis signalling game. The first model is an adaptation of the Barrett-Skyrms model for multiple messages. This adaptation allows ...

This thesis concerns a specific procedure for social choice of a group action under uncertainty. It consists of three main parts. First we investigate formal desiderata for the single agent case. Next the model~s position relative to varying disciplines is considered. Finally we provide an implem...

Would You Believe That?
The Prerogative of Assent and Utility of Disagreement
Jessica Olsen
Abstract:
By basing interpretation on belief, Davidson incurs heavy constraints regarding similarly of belief across speakers. Among these constraints is taking variance of belief to entail error. It is d...

The aim of this thesis is to investigate our experience of anxiety from a Wittgensteinian perspective. I start this investigation by offering a general conception of emotions following Wittgenstein~s conception of language and his remarks in both volumes of his Remarks on the Philosophy of Psycho...

An informational cascade is said to occur when decision-makers ignore their private information, in favor of information inferred from decisions of predecessors in a sequence. Both experimental and formal-theoretical studies have shown that informational cascades (rationally) happen. It has also ...

Compositional distributional models of meaning were introduced by Coecke et al. (2010, 2013) with the aim of reconciling the theory of distributional meaning in terms of vector space semantics with the theory of compositional interpretation as one finds it in typelogical grammars. The particular ...

The thesis aims at providing a categorical model of modified realizability, understood as an interpretation of extensional Heyting arithmetic in all finite types. Two variants of the category of partial equivalence relations are studied, namely, PER~ and PER~~. The former is shown to be not regul...

We revisit fixed-parameter tractability, fixed-parameter reducibility and kernelizability. The standard formulations of their definitions are enhanced for greater correctness from a structural complexity point of view. Doing so makes clear the distinction between fixed-parameter reducibility and...

It is becoming increasingly clear that computing systems should not be viewed as isolated machines performing sequential steps, but instead as cooperating collections of such machines. The work of Milner and others shows that 'classical' models of computation (such as the λ-calculus) are encompas...

Utterances of sentences such as I promise to come can in the right circumstances bring about the act named by the main verb, a promise in this case. They are called explicit performative utterances, and in English they typically appear with the simple present tense (perfective aspect) and not wit...

Modern approaches to human learning suggest that the process of
learning is most effective when the environment is active and
social. Digital techniques of serious games and online social networks
are therefore becoming increasingly popular in today’s educational
system. This thesis contributes t...
