1. Power politics and peace policies : Intra-state conflict resolution in southern Africa
Sammanfattning : Why do some peace agreements after intra-state war fail, while others succeed? The dissertation focuses this question, with specific attention to intra-state wars in regional security complexes. The aim of this comparative study is theory building. Propositions, indicators and research questions are derived from a typology of explanatory variables. LÄS MER
2. On the breakdown of regularity of invariant curves in quasi-periodically forced systems
Sammanfattning : In this thesis we study the process of torus collisions in one-parameter families of quasi-periodically forced dynamical systems. Specifically, we study the process whereby two invariant curves (homeomorphic to circles), one attracting and one repelling, bifurcate into a strange non-chaotic attractor. LÄS MER
3. Violence in the Midst of Peace Negotiations : Cases from Guatemala, Northern Ireland, South Africa and Sri Lanka
Sammanfattning : Why do peace talks fall apart as a result of violence? The present study addresses the question of why and how violence sometimes changes the dynamics of peace negotiation processes. Incidents of violence may produce friction between and within parties. LÄS MER
4. Dangerous Liaisons : Why Ex-Combatants Return to Violence. Cases from the Republic of Congo and Sierra Leone
Sammanfattning : After disarming and demobilizing, why do some ex-combatants re-engage in organized vio-lence, while others do not? Even though former fighters have been identified as a major source of insecurity in post-civil war societies due to their military know-how, there have been few efforts to systematically examine this puzzle. This study fills this research gap by comparing the presence or absence of organized violence in different ex-combatant communi-ties – all the former fighters that used to belong to the same armed faction and who share a common, horizontal identity based on shared war-and peacetime experiences.

5. Talking Threats : The Social Construction of National Security in Russia and the United States
Sammanfattning : Why are some issues seen as threats? This dissertation attempts to explain the dynamics of threat construction by national decision-makers. The theoretical ambition is twofold: first, the dissertation aims at improving the research on threat construction by suggesting a broad approach that analyzes this process in a structured manner.
