Arthropod Resistant Tomatoes

Tomato (Solanum lycopersicum) is one of the most economically important vegetable crops grown around globe but is a host for numerous pests and pathogens. In the future, tomato breeders will have to focus on increasing fruit quantity and on enhancing pest resistance. Many accessions of the wild relative of tomato, S. habrochaites display high levels of resistance towards arthropods such as spider mites. The presence of the sesquiterpene hydrocarbon, 7-epi-zingiberene, found in S. habrochaites type...

A Systematic Review of Mindfulness Interventions’ Impact on Athlete Emotional Distress & Wellbeing

Trevor Nathan Tierney
Mindfulness-based interventions’ (MBIs) effectiveness for improving wellbeing and reducing emotional distress is well-documented in both clinical and non-clinical sections of the general population (McAlarnen & Longshore, 2017). Although mindfulness has been shown to be effective with these populations, less is known about the specific effects for athletes. The effects of MBI’s for athletes may be different given that the intention for MBIs in the sport context is typically to improve performance, where in most other...

EFFECT OF SOCIOECONOMIC AND DEMOGRAPHIC FACTORS OF DRIVER RESIDENCE ON CRASH OCCURRENCE

Shraddha Sagar
In the U.S., road traffic crashes are a leading cause of death. Crash data from the state of Kentucky shows that the per capita crash rates and crash-related fatalities were higher than the national average for over a decade. In effort to explain why the U.S. Southeast experiences higher crash rates than other regions of the country, previous research has argued the region’s unique socioeconomic provide a compelling explanation. Taking this observation as a starting...

TEMPORAL DATA EXTRACTION AND QUERY SYSTEM FOR EPILEPSY SIGNAL ANALYSIS

Yan Huang
The 2016 Epilepsy Innovation Institute (Ei2) community survey reported that unpredictability is the most challenging aspect of seizure management. Effective and precise detection, prediction, and localization of epileptic seizures is a fundamental computational challenge. Utilizing epilepsy data from multiple epilepsy monitoring units can enhance the quantity and diversity of datasets, which can lead to more robust epilepsy data analysis tools. The contributions of this dissertation are two-fold. One is the implementation of a temporal query...

FAULT IDENTIFICATION ON ELECTRICAL TRANSMISSION LINES USING ARTIFICIAL NEURAL NETWORKS

Christopher Asbery
Transmission lines are designed to transport large amounts of electrical power from the point of generation to the point of consumption. Since transmission lines are built to span over long distances, they are frequently exposed to many different situations that can cause abnormal conditions known as electrical faults. Electrical faults, when isolated, can cripple the transmission system as power flows are directed around these faults therefore leading to other numerous potential issues such as thermal...

EFFECT OF SILICA NANOCONFINEMENT OF LIPID BILAYERS ON ITS PHASE TRANSITION AND ON THE COLLOIDAL STABILITY OF SILICA NANOPARTICLES

Aniruddha Shirodkar
In this work, we incorporated 4-(N-Boc-aminometyl) phenylboronic acid (BA), at different concentrations, into 1,2-dipalmitoyl-sn-glycero-3- phosphocholine (DPPC) bilayers confined within nanopores of two different mean pore diameters of 7.4 nm and 11.7 nm of micron sized silica particles. The confinement of DPPC into nanopores resulted in the depression in the main phase transition temperatures compared to the liposomal system. The addition of BA was found to induce disruptions in the acyl chains of the lipid molecules...

Emotional Closeness within Romantic Relationships

McKenna Fey
This study tested the existence of intergenerational transmission of romantic emotional closeness using Galovan and Schramm’s (2018) model of relationship flourishing as a theoretical backbone. Romantic emotional closeness in the present study included intimacy (i.e., self-disclosure), admiration (i.e., appreciation expression), and dyadic coping. Couples among three generations from the Panel of Analysis of Intimate Relationships and Family Dynamics (Brüderl et al., 2013) were examined to test whether romantic emotional closeness in the first generation predicted...

Queering the Carceral Cycle

Ashley Ruderman-Looff
Building upon feminist and queer scholarship that recognizes mass incarceration and the prison-industrial complex as elements of an inherently violent carceral state, Queering the Carceral Cycle excavates and analyzes twentieth-century incidents in which women resisted the state’s criminalization and/or punishment of multiply marginalized women. I argue that the state’s response to women’s acts of resistance prompted the development of new carceral strategies and technologies that expanded the carceral state’s investment in control and punishment. Moreover,...

TWILIGHT OF NEWHAVEN

Asa James Swan
In 1504, King James IV of Scotland founded the village of Newhaven, three miles north of Edinburgh on the shores of the Firth of Forth. Newhaven rose to prominence as the most well-known of Scotland’s fishing villages and reached its zenith in 1928 with the launching of its last ship, the Reliance. It was the beginning of the end of the Newhavener way of life, their twilight. This is the story of decline and domicide...

Algebraic and Geometric Properties of Hierarchical Models

Aida Maraj
In this dissertation filtrations of ideals arising from hierarchical models in statistics related by a group action are are studied. These filtrations lead to ideals in polynomial rings in infinitely many variables, which require innovative tools. Regular languages and finite automata are used to prove and explicitly compute the rationality of some multivariate power series that record important quantitative information about the ideals. Some work regarding Markov bases for non-reducible models is shown, together with...

METADATA MANAGEMENT FOR CLINICAL DATA INTEGRATION

Ningzhou Zeng
Clinical data have been continuously collected and growing with the wide adoption of electronic health records (EHR). Clinical data have provided the foundation to facilitate state-of-art researches such as artificial intelligence in medicine. At the same time, it has become a challenge to integrate, access, and explore study-level patient data from large volumes of data from heterogeneous databases. Effective, fine-grained, cross-cohort data exploration, and semantically enabled approaches and systems are needed. To build semantically enabled...

FIX SOCIETY, PLEASE

Despite their frequent utilization of mental health resources, transgender and gender diverse (TGD) adults are more likely than their cisgender counterparts to attempt suicide. While this phenomenon may inspire a myriad of explanations, the present dissertation is interested in two exploratory ideas: namely, that 1) mental health professionals may be failing their TGD clients, and 2) traditional mental health paradigms may be myopically inadequate. Paper 1 addresses the first issue by considering TGD experiences of...

Harmonizing the Disjointed

Samuel Acheampong
This dissertation consists of three essays examining the role of risk diversification in European markets. At the economy level the first two essays seek to identify whether economic integration efforts among European countries result in sharing risks to consumption with regional neighbors, as opposed to global partners. At the firm level, the third essay seeks to understand whether managers of large companies in the United Kingdom choose less financial leverage if they are specifically compensated...

NEGOTIATING MY CHINESENESS IN COLLEGE

Yan Wang
Chinese Americans are historically perceived as “perpetual foreigners” in the American political, cultural and racial discourses. People of Chinese descent have long been conceived as sharing a same ancestor as those in China. Situated in the global context of China’s rise in the world, culturally, politically and economically, this research looks at how Chinese American college students negotiate their ethnic identity in the Midwest of the United States. The current Coronavirus outbreak brought new waves...

Predicting Positive Attitudes toward Immigrants with Altruism

Kati Elizabeth Stafford
Immigration is one of the most salient and divisive issues in the US and a host of other countries, with public opinion polarized and elites deadlocked on the issue. One limitation of research on immigration attitudes is the tendency for scholars to focus exclusively on dark motivations driving hostility toward immigrants rather than those leading to compassion and support for immigrants. Using 2016 American National Election Studies (ANES) data, I examine the relationship between attitudes...

A Comparative Analysis of Reinforcement Learning Applied to Task-Space Reaching With a Robotic Manipulator With and Without Gravity Compensation

Jonathan Fugal
Advances in computing power in recent years have facilitated developments in autonomous robotic systems. These robotic systems can be used in prosthetic limbs, wearhouse packaging and sorting, assembly line production, as well as many other applications. Designing these autonomous systems typically requires robotic system and world models (for classical control based strategies) or time consuming and computationally expensive training (for learning based strategies). Often these requirements are difficult to fulfill. There are ways to combine...

Three Essays on the Economics of Education Expansion

Xiaozhou Ding
My dissertation consists of three essays that study the unintended consequences of education policies. The first two essays examine the impact of higher education expansion in China on household saving rate and individual migration rate. The third essay looks into the impact of a school redistricting plan and the construction a new school on housing prices in Fayette County, Kentucky. In the first essay, I utilize the large national expansion on higher education in China...

Maladaptive Personality Traits and Health Behaviors, Health Perceptions, and Inflammatory Biomarkers in Older Adults

Joshua Oltmanns
Traits from dimensional models of normal-range personality have been shown to predict physical health outcomes including health behaviors, health perceptions, disease, and mortality. Maladaptive traits of personality disorders may predict even more variance in physical health indicators. Dimensional models of maladaptive personality traits are replacing categorical models of personality disorder, and the five-factor model of personality disorder (FFMPD) has been shown to be a useful dimensional model of maladaptive traits. However, there has been little...

ADVANCING THE MEASUREMENT OF TRAUMA-RELATED SHAME AMONG WOMEN WITH HISTORIES OF INTERPERSONAL VIOLENCE

Alyssa Jones
Shame is a predominant emotion for some trauma-exposed individuals—particularly survivors of interpersonal violence (IPV)—that is associated with more severe symptoms of posttraumatic stress disorder (PTSD; see Saraiya & Lopez-Castro, 2016). Despite growing evidence of shame’s importance in recovery from trauma and PTSD, measurement challenges have played a large role in difficulties understanding and comparing the impact of shame across studies. These challenges include: 1) the use of measures that assess trait shame as opposed to...

AN EXPLORATION OF SMETANA’S Z DOMOVINY (FROM MY HOMELAND), TWO PIECES FOR VIOLIN AND PIANO, JB 1:118

Yeseul Kim
Z domoviny (From My Homeland), by Bedřich Smetana (1824-84), is among the most colorful and effective works for violin and piano of the 19th century, and yet it is not as well-known, nor as often performed, as many other works by Antonín Dvořák, Johannes Brahms, Pablo de Sarasate, Henryk Wieniawski and their contemporaries. This document will attempt to balance the work’s place in the repertoire and provide a performer’s guide. It consists of an historical...

MAST CELLS AS NOVEL EFFECTOR CELLS IN THE PATHOGENESIS OF CHRONIC GRAFT-VERSUS-HOST DISEASE

Ethan Strattan
Hematopoietic stem cell transplantation (HSCT) is most commonly a treatment for inborn defects of hematopoiesis or acute leukemias. Widespread use of HSCT, a potentially curative therapy, is hampered by onset of graft-versus-host-disease (GVHD), a condition wherein the donor cells recognize the patient tissues as non-self. GVHD can manifest anywhere from weeks to decades post-transplant and is classified as either acute or chronic GVHD, both of which are significant causes of transplant-related morbidity and mortality. However,...

Examining the Impact of Social Media Use on Body Dissatisfaction and Eating Disorder Symptomatology Among Adolescents

Ilyssa P. Salomon
Media exposure is often cited as a causal factor in the development of body dissatisfaction, or negative thoughts and feelings toward the body (Grogan, 2017; Thompson, Heinberg, Atlabe, & Tantleff-Dunn, 1999). While eating disorders most commonly emerge during late adolescence (18-21 years), risk factors that predict the later onset of eating disorders emerge much earlier and escalate during adolescence (13-16 years; Hudson, Hiripi, Pope, & Kessler, 2007; Rhode, Stice, & Marti, 2016). Overall, links between...

Algorithms for Achieving Fault-tolerance and Ensuring Security in Cloud Computing Systems

Md Tariqul Islam
Security and fault tolerance are the two major areas in cloud computing systems that need careful attention for its widespread deployment. Unlike supercomputers, cloud clusters are mostly built on low cost, unreliable, commodity hardware. Therefore, large-scale cloud systems often suffer from performance degradation, service outages, and sometimes node and application failures. On the other hand, the multi-tenant shared architecture, dynamism, heterogeneity, and openness of cloud computing make it susceptible to various security threats and vulnerabilities....

EFFECTS OF APERIODICITY AND FRUSTRATION ON THE MAGNETIC PROPERTIES OF ARTIFICIAL QUASICRYSTALS

Barry Farmer
Quasicrystals have been shown to exhibit physical properties that are dramatically different from their periodic counterparts. A limited number of magnetic quasicrystals have been fabricated and measured, and they do not exhibit long-range magnetic order, which is in direct conflict with simulations that indicate such a state should be accessible. This dissertation adopts a metamaterials approach in which artificial quasicrystals are fabricated and studied with the specific goal of identifying how aperiodicity affects magnetic long-range...
