abstract: This research conducts two methods of rhetorical analysis of State of the Union Addresses: 1. Computational linguistic analysis of all State of the Union Addresses from 1790-2007, and 2. Close-readings and rhetorical analyses of two addresses: one by President Truman and one by President Reagan. This research shows the following key findings: 1. I am able to see general shifts in the authors' approaches to the State of the Union Address through historical computational analyses of the content of all speeches, and 2. Through close readings, I can understand the impact of the author's ethos and the historical context on the addresses, something that would not be readily revealed in a computational analysis. This study starts with a historical computational linguistic analysis of all State of the Union Addresses between 1790 and 2007. The study follows with close-readings of two State of the Union Addresses from the early and late Cold War period in-context: 1. Harry Truman's 1951 Address and 2. Ronald Reagan's 1986 Address. The main conclusions drawn from this research are that close-readings of State of the Union Addresses cannot be replaced by computational analyses, but can work in tandem with computerized text analysis to reveal shifts in rhetorical and topical features. This paper argues that there must be more close analyses in coordination with large-scale text analysis in order to understand the complexities of rhetorical situations. / Dissertation/Thesis / Ph.D. English 2013

Nestas redes, os nós agem de maneira cooperativa, encaminhando pacotes uns aos outros, de forma a possibilitar a comunicação entre pares de nós que se encontram fora do alcance direto de transmissão sem fio. Nos últimos anos, as pesquisas direcionadas à MANETs têm recebido grande atenção do governo, academia e indústria. Contudo, ainda existem algumas questões em aberto relativas à implantação de MANETs que impedem o desenvolvimento de aplicações reais e difusão das mesmas. O avanço das pesquisas nesta área poderia melhorar o desempenho atual no uso destas redes, bem como propiciar o surgimento de novos campos de aplicação. Além disso, ainda existe um grande potencial econômico a ser explorado no que se refere ao uso de redes móveis ad hoc. Um dos principais desafios relativos à implantação de MANETs é a configuração adequada dos endereços de rede. Tais endereços precisam ser únicos dentro do mesmo domínio de roteamento, ou em outras palavras, um MANET não deve conter dois dispositivos configurados com o mesmo endereço de rede. A configuração estática dos nós ad hoc não é viável devido à natureza dinâmica destas redes, e esquemas tradicionais desenvolvidos para as redes infraestruturadas não são adequados. Estas questões motivaram algumas pesquisas destinadas à permitir que os nós se configurarem sem intervenção humana, resultando em uma série de métodos para configuração automática de endereços. Estas soluções, no entanto, apresentam uma série de limitações, relacionadas principalmente à aplicabilidade em cenários restritos ou introdução elevada de sobrecarga na rede. Este trabalho apresenta um método escalável e eficiente para alocação e organização do espaço de endereçamento em redes móveis ad hoc. Uma revisão bibliográfica dos trabalhos existentes é apresentada, considerando as vantagens e limitações de cada um. Por fim, o trabalho apresenta uma avaliação preliminar do método proposto, considerando diferentes cenários e métricas

In three papers, I consider two questions of nationalization in American politics, and one question of the methodology necessary to study them. Nationalization is the process by which local politics become more like national politics on the basis of political issues and electoral engagement. It is usually measured using the difference in presidential and state-level electoral returns over time. To expand the study of nationalization, I use automated content analysis to derive new measures for the phenomenon’s study based on political text. In particular, I apply automated content analysis via latent dirichlet allocation to code for salient topics in text from national political agenda speech, local agenda speech, and state laws. The primary source for these local agenda codes is a novel database of State of the State addresses, which are like presidential State of the Union addresses, but are delivered by governors. I developed the database over the past seven years as part of this dissertation; it draws from all 50 States, and the earliest captured addresses date to the year 1893. The secondary sources for these codes are the State of the Union addresses and a corpus of laws passed by state legislatures. I utilize the codes from these naturally distinct text corpora to study the nationalization of the political agenda, and how nationalized elections relate to the production of salient laws. The comparison of naturally distinct texts, however, is problematic and requires further examination. To that end, the first paper, “A Theory and Method for Pooling Naturally Distinct Corpora” concerns the theory and method for why we should be able to use, pool, and compare the computer-generated codes from these naturally distinct text corpora to study nationalization. I propose a theoretical framework with which the researcher may defend the pooling of corpora, and introduce an empirical approach to testing for absolute comparability, the delta-statistic. While statistics like the Akaike Information Criterion (AIC) and penalized log likelihood can help the researcher to determine if a model fits the pooled corpora better than the corpora separately, the delta-statistic relies on a strong theory of latent traits to evaluate the absolute quality of a pooled model. This is especially important when it is impossible to evaluate ground truth fit because some data are unlabeled. The second paper, “Have State Policy Agendas Become More Nationalized?” examines whether the nationalization of state policy agendas is related to the nationalization of gubernatorial elections. The analysis shows that State agendas, as laid out in the State of the State addresses, have become more similar to each other over time. It also shows that State agendas have become more similar to the national agenda, as laid out in the State of the Union addresses. Finally, I demonstrate an increasing relationship between the similarity in the agenda and the nationalization of elections. The findings suggest that the nationalization of the agenda is a significant and related factor to the nationalization of elections. The third paper, “Can States Govern Effectively When Politics Are Nationalized?” considers the question of whether electoral nationalization moderates the relationship between divided government and legislative productivity in the states. I find a null effect of divided government on salient lawmaking ability, and that nationalization of state legislatures has generally decreased the production of salient laws. The result holds even though nationalization is unrelated to the ability of our state governments to take action on salient issues during times of divided government. The findings suggest that behavioral factors driving lawmaker decisions may be more to blame for lawmaking defects than institutional ones. Taken together, the essays demonstrate the value of text analysis to the analysis of nationalization and other research topics in American politics.
