2. Fractures in the Fabric of Democracy? : Change and Continuity in Public Opinion in Contemporary Europe
Abstract : Is representative democracy in Europe becoming undermined by developments in public opinion? This dissertation addresses this overarching question, by studying the development over time of (i) ideological polarization; (ii) the degree to which vote choices are structured by political attitudes; and (iii) the degree to which parties are internally congruent in political opinion across levels. Public opinion is understood as the metaphorical ‘fabric’ of representative democracy, where conjectures to the fact of a fracturing dynamic are plausible and recurrent in academic and public debate.

The two dominant, competing streams of prior work have emphasized either the importance of state power or that of mass opinion in these processes in order to explain why some regimes successfully maintain their grip on power, while others make gradual steps towards democratization.

5. Interacting particle systems for opinion dynamics: the Deffuant model and some generalizations
Abstract : In the field of sociophysics, concepts and techniques taken from statistical physics are used to model and investigate some social and political behavior of a large group of humans: their social network is given by a simple graph and neighboring individuals meet and interact in pairs or small groups. Although most of the established models feature rather simple microscopic interaction rules, the macroscopic long-time behavior of the collective often eludes an analytical treatment due to the complexity, which stems from the interaction of the large system as a whole.
