Why do individuals engage in violence against the state? This research investigates the biological and environmental determinants of individual-level participation in political violence through the use of a Candidate Gene Association, gene-environment interaction, study. Existing research has demonstrated that variation in a specific gene (called MAO-A) is associated with aggression. However, relatively little scholarly attention has been paid to the interaction with the environment; specifically, the ways in which repressive political environments differentially incite acts of violence. Using original genetic, survey and experimental data collected on participants and non-participants of political violence, I find that under conditions of political repression, individuals with the low MAO-A genetic variant are significantly more likely to engage in acts of political violence. By examining both the genetic and environmental factors influencing political violence, the results make a significant contribution to our understanding of how genetic variation may lead to violence.

| Summary/Abstract |
Self-determination claims have abounded in the international system since the end of World War II. But these claims have not emerged everywhere. About half of the states in the international system face some challenge related to self-determination today. Why do some states face these demands while others do not? We argue that ethno-national self-determination is one of many identities with which individuals can find affinity. While an international norm related to self-determination has developed globally, its use as a basis for political claims has diffused regionally. Diffusion of self-determination occurs through observation of others using self-determination as a basis of organization, generating a sense of legitimacy, sensitivity to related grievance, and perceptions of tangible benefits related to self-determination identification. We test this empirically on global data on self-determination claims from 1960 to 2005 and find evidence of spatial diffusion, suggesting that self-determination is, to some extent, contagious.

| Summary/Abstract |
Many studies highlight the role that international intervention can play in prolonging civil wars. Yet, direct military intervention is just one way that external actors become involved in civil conflicts. In this article, a model is developed and analyzed that shows that when the government is unsure about how external support to the rebels will help rebel war-making capacity, it is the government that will continue fighting rather than settle the dispute. Different types of external support to rebels influence their fighting capacity differently, and some types of support create uncertainty about how new resources will translate into war-making ability. Specifically, more fungible sources of support (such as direct financial support) generate the most uncertainty for states as they attempt to estimate the effect of support to rebels on the conflict. Increased uncertainty inhibits bargained settlement, and disputes characterized by fungible external support are less likely to end than those where rebels receive different kinds of support. Empirical analyses demonstrate strong support for this argument; rebels that receive highly fungible external support (money and guns) are less likely to see conflict termination than rebels that do not.
