My dissertation focuses on methods for working with multilayer network representations of complex interdependent systems. I apply these methods to examine the influence transnational actors have on international cooperation.
Statistical Inference for Multilayer Networks in Political ScienceAbstract Interactions between units in political systems often occur across multiple relational contexts. These relational systems feature interdependencies that result in inferential shortcomings and poorly-fitting models when ignored. General advancements in inferential network analysis have improved our ability to understand relational systems featuring interdependence, but developments specific to working with interdependence that cross relational contexts remain sparse. In this paper, I introduce a multilayer network approach to modeling systems comprising multiple relations using the exponential random graph model (ERGM). In two substantive applications, the first a policy communication network and the second a global conflict network, I demonstrate that the multilayer approach affords inferential leverage and produces models that better fit observed data.
Transnational Scientific Communities Facilitate Cooperation in the International Nuclear Regime: Evidence from the Pugwash MovementAbstract In this paper I show how transnational scientists influence international cooperation on nuclear treaties. I propose a delegation-based theory for how the transnational scientific community can influence state behavior by providing informational resources to help governments overcome hurdles to cooperation. Internationalist-oriented scientists obtain these informational resources by engaging each other through informal diplomacy. At the same time, they are constrained by what states consider to be permissible, which results in the observed bidirectional influence between state and scientist behavior. In the empirical analysis, I create a network data set from archival data on the Pugwash movement, a transnational community of scientists lobbying for increased extranational control over nuclear technology. I jointly model the international nuclear treaties and transnational Pugwash networks as a multilayer network. Results indicate that mutual reinforcement between the two sets of cooperative ties is a generative feature of the network. Additional evidence showing that results are stronger in open political systems, which afford scientists access to state officials, provides support for the proposed informational mechanism behind this relationship.
