On the Fence

Description: Living the vast majority of my life in an area that celebrates diversity but thrives because of illegal cross-border activities (undocumented workers, drug imports) at times the distance between the United States and Mexico is in fact as thin as the width of a fence. Though it is typical for a filmmaker to hope to present a unique take on a subject, given how I have seen the topics of immigration and the perspective of the purpose of homeland security portray, I am confident that there is an op… more

Not All Truth Commissions Are Alike: Understanding Their Limitations and Impact

Description: This dissertation project develops a theoretical understanding of how truth commissions achieve legitimacy and thus contribute to peace and stability in the aftermath of major traumatic events (e.g. civil war, mass killings, regime changes). I identify three components of truth commission legitimacy---authority, fairness, and transparency---that facilitate beneficial outcomes for societies emerging from a period of severe human rights repression or civil war. I theorize and test how institution… more

Why Be Friends? Amicus Curiae Briefs in State Courts of Last Resort

Description: While there has been a substantial body of research on interest group activity in U.S. federal courts, there has been comparatively little analysis of interest group engagement with state courts. Given that state courts adjudicate the vast majority of cases in the American legal system and very few cases are appealed to the Supreme Court, understanding why organized interests participate in these courts is of great importance. The present study analyzes interest group involvement as amicus curi… more

A Contemporary Application of Boris Goldovsky’s Method for Training the Operatic Singer-actor: a Model for Today’s University Opera Workshop Instructor

Description: Throughout the twentieth century, Boris Goldovsky (1908-2001) played a significant role in training the operatic singer-actor. One of his most significant contributions was integrating music and drama. He taught his students how to develop a character, how to find dramatic clues in the music, and to become expressive artists free from monotonous operatic gestures and posturing. As author of the first textbook for training the operatic singer-actor, his curriculum was developed from experience, … more

Electoral Rules, Political Parties, and Peace Duration in Post-conflict States

Description: This dissertation examines the following research question: Which types of electoral rules chosen in post-conflict states best promote peace? And are those effects conditional upon other factors? I argue that the effects are conditional upon the types of political parties that exist in the post-conflict environment. Although this explanation is contrary to scholars that speak of political parties as products of the electoral system, political parties often predate the choice of electoral system… more
