1. Efficient sampling of Bayesian posteriors and predictive distributions in χEFT
Abstract : In this thesis I employ Bayesian statistics to quantify parametric and epistemic uncertainties in chiral effective field theories (χEFT) and propagate these forward to predictions of observables in low-energy nuclear physics. Two primary sources of uncertainty---experimental errors and the theoretical error induced by the truncation of the EFT at up to next-to-next-to-leading-order---are modelled and accounted for in the posterior distributions of the unknown low-energy constants (LECs) that govern interaction strengths in χEFT.

2. Elusive Peacemakers : A Bargaining Perspective on Mediation in Internal Armed Conflicts
Abstract : This composite dissertation explores mediation in internal armed conflicts from a bargaining perspective. Four separate essays investigate why mediation occurs, why it is successful, and why peace guarantors’ commitments are credible. Essay 1 examines the conditions under which mediation takes place.

3. Extending the reach of uncertainty quantification in nuclear theory
Abstract : The theory of the strong interaction—quantum chromodynamics (QCD)—is unsuited to practical calculations of nuclear observables and approximate models for nuclear interaction potentials are required. In contrast to phenomenological models, chiral effective field theories (χEFTs) of QCD grant a handle on the theoretical uncertainty arising from the truncation of the chiral expansion. READ MORE

4. Compliance with Territorial Awards : Territorial Concessions, Domestic Constraints, and International Legal Rulings
Abstract : Under what conditions do states engaged in interstate territorial disputes comply with unfavorable international legal awards? Interstate territorial disputes have proven to be a major threat to international peace and security. Of the available options for the peaceful resolution of territorial claims, legal dispute resolution has proven to be very effective, as states overwhelmingly comply with international awards.

5. International organizations as peacemakers : The evolution and effectiveness of intergovernmental instruments to end civil war
Abstract : Across four self-contained essays, this dissertation seeks to identify which features make international organizations (IOs) effective peacemakers in modern civil wars. The first essay introduces an original dataset on the institutional design of 21 peace-brokering IOs between 1945 and 2010. READ MORE
