Constructing Taiwan: Taiwanese Literature and National Identity

Description: In this work, I trace and reconstruct Taiwan's nation-formation as it is reflected in literary texts produced primarily during the country's two periods of colonial rule, Japanese (1895-1945) and Kuomintang or Chinese Nationalist Party (KMT) (1945-1987). One of my central arguments is that the idea of a Taiwanese nation has historically emerged from the interstices of several official and formal nationalisms: Japanese, Chinese, and later Taiwanese. In the following chapters, I argue that the co… more

Naming and Shaming Non-State Organizations, Coercive State Capacity, and Its Effects on Human Rights Violations

Description: Scholars generally assume that states are shamed for their own behavior, but they can also be shamed for the lack of investigation for violence perpetrated by domestic non-state actors. I engage this previously-unstudied phenomenon and develop a theory to explain how states will respond to being shamed for failing to control domestic violence. I examine two types of outcomes: the governments' change in behavior, and the accountability efforts against state agents that have abused human rights. … more

Genomic Island Discovery through Enrichment of Statistical Modeling with Biological Information

Description: Horizontal gene transfer enables acquisition and dissemination of novel traits including antibiotic resistance and virulence among bacteria. Frequently such traits are gained through the acquisition of clusters of functionally related genes, often referred to as genomic islands (GIs). Quantifying horizontal flow of GIs and assessing their contributions to the emergence and evolution of novel metabolic traits in bacterial organisms are central to understanding the evolution of bacteria in genera… more

Giving Texas Veterans a Voice: Traumatic Experience and Marijuana Use

Description: Disabled veterans with post-traumatic stress disorder (PTSD) exist in a category separate from many civilians and soldiers. Their experiences land them in a category distinctly marked as atypical. The standard protocol to manage this atypical subject position is prescription drugs- a mark of the ill. In a distorted, post-war American society, what happens when veterans with PTSD refuse to be labeled as ‘sick,' ‘different,' or even ‘disabled'? This thesis explores the actions and intricacies of … more

Microcantilever Based Viscosity Measurement as it Applies to Oscillation Amplitude Response

Description: The goal of this research is to measure viscosity via the analysis of amplitude response of a piezo driven vibrating cantilevers partially immersed in a viscous medium. As a driving frequency is applied to a piezoceramic material, the external forces acting on the system will affect its maximum amplitude. This thesis applies this principle through experimental and analytical analyses of the proportional relationship between viscosity and the amplitude response of the first natural frequency mod… more

A National Idiom Universally Understood: Brazilian Tradition and Personal Evolution in Osvaldo Lacerda's "Variações e Fuga para quinteto de sopros"

Description: The career of Osvaldo Lacerda (1927-2011) spanned a critical time in the development of Brazilian nationalist music. Though he was an outspoken nationalist composer, he was also influenced by European trends and training. Even within his nationalist compositions, evidence of a shift in style that mirrors the European movements of Modernism and Postmodernism is found in his works. Among his thirty-six chamber works, three are wind quintets, written between 1962 and 1997. Although all three works… more

Assessing Perception and Attitude of Pianists toward Ergonomically Scaled Piano Keyboards (ESPK): Raising Awareness about ESPK and Evaluating Changes of Attitude through an Educational Survey

Description: As epidemiologic research demonstrates health concerns for hand problems among pianists, scientists are measuring historic piano keyboards and realizing that much of the piano literature was composed for and played on pianos with smaller keys compared to what is used on the modern piano. Having to play this literature on a larger keyboard is especially difficult for small-handed piano students and professionals. Fortunately, smaller keyboards are now available for use with standard pianos - and… more

Conformal and Stochastic Non-Autonomous Dynamical Systems

Description: In this dissertation we focus on the application of thermodynamic formalism to non-autonomous and random dynamical systems. Specifically we use the thermodynamic formalism to investigate the dimension of various fractal constructions via the, now standard, technique of Bowen which he developed in his 1979 paper on quasi-Fuchsian groups. Bowen showed, roughly speaking, that the dimension of a fractal is equal to the zero of the relevant topological pressure function. We generalize the results of… more

The Predictive Utility of Personality Facets in Examining Risk and Resiliency in Transient and Chronic Stress

Description: Chronic or prolonged stress has been shown to have deleterious impacts on mental health, physical health, and cognitive functioning. However, not all individuals show the negative effects of continued exposure to stress. Past research has identified personality as a contributor to resiliency, while also identifying it as an important predictor of negative outcomes, such as psychopathology. More recently, personality researchers have emphasized the importance of examining personality at the leve… more

Assessment of Caregiver Generalization of Reinforcement to the Natural Environment in a Large Residential Facility and Use of Prompting and Feedback to Improve Performance

Description: Behavioral skills training (BST) is often used to train caregivers to implement various behavior management procedures; however, additional strategies are sometimes required to promote the generalization of skills from a contrived setting to the natural environment. Generalizing skills to the natural environment requires that the caregiver's behavior transfer from control of stimuli in the contrived setting to stimuli in the natural environment, and the skill continues to be performed with high… more

Computational Methods to Optimize High-Consequence Variants of the Vehicle Routing Problem for Relief Networks in Humanitarian Logistics

Description: Optimization of relief networks in humanitarian logistics often exemplifies the need for solutions that are feasible given a hard constraint on time. For instance, the distribution of medical countermeasures immediately following a biological disaster event must be completed within a short time-frame. When these supplies are not distributed within the maximum time allowed, the severity of the disaster is quickly exacerbated. Therefore emergency response plans that fail to facilitate the transpo… more
