  2. 2. On the breakdown of regularity of invariant curves in quasi-periodically forced systems

    Author : Thomas Ohlson Timoudas; Kristian Bjerklöv; Joaquim Puig; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dynamical systems; strange attractors; Schrödinger cocycles;

    Abstract : 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. READ MORE

  3. 3. Violence in the Midst of Peace Negotiations : Cases from Guatemala, Northern Ireland, South Africa and Sri Lanka

  4. 4. Dangerous Liaisons : Why Ex-Combatants Return to Violence. Cases from the Republic of Congo and Sierra Leone

    Author : R. Anders Nilsson; Thomas Ohlson; Kristine Höglund; Mats Hammarström; Joanna Spear; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ex-combatants; reintegration; demobilization; DDR; conflict resolution; peacebuilding; civil wars; Republic of Congo; Sierra Leone; Peace and conflict research; Freds- och konfliktforskning;

    Abstract : 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.

    Abstract : 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.
