Insights into Static Solute Strengthening and Dynamic Strain Aging Behavior of Hexagonal Close Packed Mg Alloys

Mohammed Shabana
The addition of solutes to hexagonal close packed (HCP) Mg has been extensively studied due to interests in the broad applicability of strong and lightweight alloys. However, the use of solute strengthening can pose challenges when manufacturing processes or operating conditions force the material into a range of temperatures and strain rates at which the alloys exhibit a negative strain rate sensitivity, a phenomenon which has come to be known as dynamic strain aging (DSA)....

Psychobehavioral Factors and Cardiovascular Disease Risk in Family Caregivers

Soojung Ahn
Increased cardiovascular disease (CVD) risk in family caregivers is well documented. Caregivers’ vulnerability to declines in cardiovascular health may be attributed to psychological symptoms and alterations in health behavior resulting from caregiving demands. Subclinical CVD markers have shown prognostic significance in various populations, yet caregivers have rarely been assessed for their CVD risk using the surrogate markers. Therefore, the goal of this study is to investigate the relationships among psychological and behavioral factors and CVD...

ViWatch: Harness Vibrations for Fine-Grained On-Body Interfaces with a Commodity IMU Sensor

Wenqiang Chen
Wearable devices like smartwatches and smart wristbands have gained substantial popularity in recent years. While enabling a variety of computing applications, such devices are not always convenient to interact with because of the limited size of the touchscreen. A wide variety of approaches have been considered to improve their user experiences, ranging from using customized RF sensors, to multiple sensors in smartwatches. These solutions all have limitations related to the characteristics of their technology. We...

MORE THAN A MEGAPHONE: THE IMPACT OF SOCIAL MEDIA ON POLITICAL LEADERS' FOREIGN AFFAIRS COMMUNICATION IN THE U.S. AND TAIWAN

Hsuan-Yu Lin
This three-essay dissertation explores the impact of social media on international security, especially whether social media gives political leaders leverage to shape public opinion about foreign policy. The Democratic Peace Theory suggests public opinion is one of the main constraining factors of political leaders’ aggressive foreign policies. If social media empowers political leaders to shape public opinion, then social media may reduce political leaders’ potential costs of seeking a risky foreign policy. However, existing literature...

Adenosine Regulation of Adipose Tissue Lipid Metabolism

Mitchell Granade
Adipose tissue is a critical regulator of energy balance that must rapidly shift its metabolism between fasting and feeding to maintain homeostasis. During feeding, adipose tissue acts as a physiological buffer for excess energy through lipid storage, while adipocyte lipolysis provides the body with a necessary source of energy through fatty acids during fasting. The dysregulation of these processes contributes to the development of metabolic syndrome and type 2 diabetes, so it is essential that...

Interlocking Erasures: U.S. Empire, Whitness, and the Terraforming of Politics

Heidi Nicholls
Many scholars have determined that racism is a structural problem that is continually reproduced through a racialized social system and are able to account for how racism has changed over time, from explicit and overt to seemingly “colorblind” mechanisms (Bonilla-Silva 1997, 2015; Omi and Winant 2015). However, few approaches have addressed how changes in racism over time relate to the territorial expansion of the United States. As a result, scholarship in sociology tends to characterize...

Intimate Editing: Toward a Relational Philological Poetics

Anne Marie Thompson
According to the etymology of “philo-logy,” poets—the most ardent lovers of words—ought to be considered first among philologists. However, philology’s reputation as a dusty, pedantic science has seen it relegated to the back shelf of literary studies. “Intimate Editing” reveals a counterintuitive but symbiotic relationship between innovative poetry and philology: if philology engages with words' material incarnations in documents, manuscripts, and books, a philological poetics calls attention to and intervenes in that process. The contemporary,...

High-Performance Infrared Photodetectors Based on AlInAsSb Digital Alloy Materials System

Dekang Chen
The mid-wave infrared (MWIR) spectrum, typically referring to the wavelength range of 2 - 5 µm, has the potential to enable next-generation breakthroughs in photonics applications. Therefore, high-performance photodetectors that operate in this range are of high interest. However, high signal-to-noise ratio (SNR), a critical figure of merit for photodetectors, is extremely difficult to achieve in the MWIR range. The challenge is twofold, one is the low signal power level, determined by the application scenario...

The Origins of Authoritarian Rule: Three Essays on the Make-up of the Ruling Coalition, Domestic Politics, and International Conflict

Simonas Cepenas
This dissertation explores the origins of authoritarian rule and its effects on the make-up of the ruling class, and consequently, on domestic politics and international conflict. I argue that the origins of authoritarian rule set long-lasting trajectories that continue to shape authoritarian politics for decades. Authoritarian regimes are categorized based on whether the founding leader of authoritarian regime transforms the social and political life of the preexisting state or relies on the social order and...

Exploring Issues of Race and Equity in Early Education: A Closer Look at Teacher Perceptions and Child Exclusionary Discipline Experiences

Maria Accavitti
This dissertation is comprised of three independent studies that each address gaps in the literature around racial discipline inequities in early childhood. Paper 1 investigated differing teacher perceptions of specific subtypes of disruptive behavior between Black and White children at preschool entry. Paper 2 gathered comprehensive and nuanced qualitative information about practices beyond suspension and expulsion that exclude young children from learning opportunities. Finally, Paper 3 examined whether racial discipline inequities extended to soft exclusionary...

Investigating Diacylglycerol Kinase Function and Regulation Using Chemical Proteomics and MassSpectrometry Lipidomics

Roberto Mendez
Diacylglycerol kinases (DGKs) regulate cell metabolism and signaling through poorly defined mechanisms with regards to lipid specificity. My thesis work aims to bridge gaps in our knowledge by investigating isoform-specific functions of DGKs using chemoproteomic and lipidomic methods. We aim to apply novel technologies to explore DGKs to unravel how individual members of this enzyme family can regulate distinct cell biology. We have made progress in determining DGKθ-mediated alterations in the lipidome. These studies have...

A Multi-frequency VLA Continuum Investigation of Starburst & AGN Activity in Local U/LIRGs

Yiqing Song
The rates at which galaxies form stars have been declining since ~ 3 billion years after the Big Bang. Massive stars that drive the chemical enrichment of the Universe are now being produced at much lower rates in the Milky Way and most other galaxies in our local Universe, compared to galaxies at z ~ 1-2, when most stars formed. During this distant era of rapid growth, star formation took place primarily in Luminous and...

Exploring the Southern Vampiresses of Southern Gothic Literature through Kristeva's Abject Theory

Stirling Smith
For the French literary theorist Julia Kristeva, abjection refers to a person’s rejection of an object which blurs the distinction between the self and other. The horror, the shame, the disgrace, the taboo, the perverse – the situations, objects, and thoughts that we inherently separate ourselves from because they are too disgusting, too horrible, too distasteful to associate ourselves with – are the facets of our lives that we repel and reject. They are parts...

The Effect of Social Support on Frontal Asymmetry: Neural Reactivity to Social Support and Longitudinal Outcomes

Nauder Namaky
The perception of adequate social support is associated with an extension of life expectancy of the same magnitude as many recommended health behaviors (Holt-Lunstad et al., 2010). Mechanistic pathways proposed to explain this phenomena include biological (Ozbay et al., 2007; Reblin & Uchino, 2008)⁠, behavioral (Reblin & Uchino, 2008; Umberson, 1987)⁠, and psychological (Uchino et al., 1996, 2012)⁠ pathways. However, the extant literature has not examined the means by which perceived social support exerts benefits...

The gut commensal microbiome remotely regulates mammary tissue mast cells to induce metastatic dissemination of HR+ breast cancer

Tzu-Yu Feng
Metastatic breast cancer is a treatable but uncurable disease. Around 75% of patients with metastatic breast cancer were diagnosed with hormone-receptor positive (HR+) breast tumors, highlighting the need to further define the factors that enable metastatic dissemination of HR+ breast cancer cells. According to the recent epidemiological results, HR+ breast cancer patients experienced heterogeneous outcomes, despite receiving comparable treatments. These data raise the possibility that tumor-independent factors influence metastatic capacity of HR+ tumor cells. Our...

Racism Predicts White Individuals' Tolerance for Wrongful Conviction

Crystal Slane
Previous research indicates that wrongful convictions disproportionately affect Black people. In this dissertation, I investigate whether racism and the desire for hierarchy motivate White individuals’ level of acceptance of wrongful convictions. I tested the following four predictions: Hypothesis 1: White individuals with higher levels of racism will be more tolerant of wrongful convictions in society than those with lower levels of racism. Hypothesis 2: White participants will be more tolerant of wrongful convictions when they...
