Race And Technology In Southern Literature, Civil War To Civil Rights, Kaitlyn Elizabeth Smith

Theses and Dissertations

This dissertation considers the intersection of technology and race in the literature of the American South from the nineteenth and twentieth centuries. Though narratives about technology in American literature often promise democracy, equality, improvement, and progress, the role of technology in southern literature is more complex and ambivalent. Literature from and about the South from the Civil War to the civil rights era, by Black and white southern authors like Charles Chesnutt, Zora Neale Hurston, William Faulkner, and Eudora Welty reveals technology’s ability to uphold and naturalize southern white supremacy, but also to subvert it. Southern literature traces a pattern …

Alexa, Should I Trust You? A Theory Of Trustworthiness For Artificial Intelligence, Elizabeth K. Stewart

Theses and Dissertations

As people turn to AI driven technologies for help with everything from meal planning to choosing a mate, it is increasingly important for individuals to gauge the trustworthiness of available technologies. However, most philosophical theories of trustworthiness focus on interpersonal trust and are inappropriate for non-agents. What, then, does it mean for non-agents such as AI driven technologies to be trustworthy? I distinguish two different forms of trustworthiness: naive trustworthiness and robust trustworthiness. An agent is naively trustworthy to the extent that it would be likely to meet the truster’s expectations with respect to a given domain. An agent is …

Infertility Education For Men With Cystic Fibrosis And Its Effects: Outlooks On Fertility And Birth Control, Allison Elizabeth Perez Szczepanski

Theses and Dissertations

Many men with Cystic Fibrosis (CF) are infertile; however, few studies have evaluated fertility outlook of men with CF since the advent of modulator therapy. As predicted survival and quality of life improve, family planning is an area of increased interest for the CF community. The current study surveyed men with CF to explore their outlook on fertility, family planning, and birth control use with the option to receive a home fertility test and follow-up interview with study staff.

Seventy-five men with CF completed the survey and 53 (71%) believed they were likely infertile. Most recalled learning about infertility between …

The difficulty of analyzing the injury data set is that the …

Tailored Nanomaterials For Advancing Fast-Charge Research, Wessel Van Den Bergh

Theses and Dissertations

The demand for fast, energy-dense storage has driven research into nanoscale intercalation materials. Nanoscale materials not only accelerate kinetics but also can modify reaction path thermodynamics, intercalant solubility, and diffusivity. Pioneering works have revealed such nanoscale changes, often without the need to separately probe each fundamental transport process. While electrodes can be designed to have one transport processes dominant, there remain opportunities to better understand energy-dense designs with multiple concomitant transport constraints. The contents herein highlight emerging an method using tailored, energy-dense nanomaterials and the process of elimination to clearly correlate architectural features to performance. For example, this method revealed …

Lexical And Syntactic Priming In Dialogue, Sarah Campbell Wilson

Theses and Dissertations

Speakers engaged in dialogue align with one another across multiple linguistic levels to ensure effective communication. The Interactive Alignment Model (Pickering & Garrod, 2004) suggests speakers align due to automatic priming mechanisms at individual linguistic levels. Syntactic priming is the tendency to repeat a syntactic structure that has been recently comprehended or produced. Although syntactic priming is regarded as an automatic, abstract structural phenomenon, other linguistic factors can influence a syntactic structure’s priming strength. Lexical repetition between structures has been shown to enhance syntactic priming, an effect termed “lexical boost” (Branigan et al., 2000; Healey, Purvery, & Howes., 2014). Another …

Adsorption Of Microcystins To Sediment Affects Their Bioavailability And Remediation, Ashley Womer

Theses and Dissertations

The freshwater harmful algae Microcystis spp produces a family of toxins called microcystins1. These species of algae are known to release microcystins from their cells directly into the surrounding water2. This creates an array of human health risks depending on the fate and transport of the toxins in the water column3,4. Risk modelling and previous literature has shown that sediment is a sink for free microcystin, microcystin can be stably adsorbed to sediment for hundreds of years, and its adsorption to sediment is determined by the sediment adsorption partitioning coefficient (Kd)5,6,7. In this work it is hypothesized that the sediment …

How The Level Of Firm Support For Employee Volunteering Affects Employee Work Productivity And Altruistic Behavior Inside The Firm, Xiaomei Xiong

Theses and Dissertations

Employee volunteering refers to employees giving time to volunteer for charitable causes with explicit support from their employer. Offering support for employee volunteering is one of the fastest-growing areas of employee benefits. Using a laboratory experiment, I examine the effectiveness of individual employee volunteering programs in motivating employees’ altruistic behavior outside the firm, as well as their work productivity and altruistic behavior inside the firm. I predict and find that the level of firm support for employee volunteering not only affects employees’ volunteering engagement outside the firm, but also affects employees’ work productivity inside the firm. Moreover, I predict and …

Essays On Delegation Under Migrating Technologies: The Case Of Mobile Network Value Chain, Fan Zou

Theses and Dissertations

The fast expansion of the mobile services market has propelled the growth of MVNOs to reach an expected 7.4% of the global market and, even higher, 8.1% of the North American market by 2022 (Research&Markets 2017), which reaches a total size of 90 billion US dollars. The growth of MVNOs, meanwhile, has complicated implications for MNO market performance because of the fast industry clockspeed, under which new mobile network technologies inevitably overlap with existing technologies (Tilson and Lyytinen 2006). Adding MVNOs to the value chain allows MNOs to develop proper growth strategies by exploring new technologies balanced against exploiting existing …

Rational Synthesis Of Ultra-Small And Durable Platinum-Based Catalysts For Renewable Energy Applications, Fahim Bin Abdur Rahman

Theses and Dissertations

Ultrasmall supported platinum nanoparticles (Pt NPs) are often used in two promising renewable energy production technologies – hybrid-sulfur water splitting for actively catalyzing H2SO4 decomposition and in fuel cells for the oxygen reduction reaction (ORR). However, the stability of Pt NPs under reaction conditions is the ultimate challenge for these processes. Two prevalent ways to overcome this challenge are improving stability by anchoring Pt onto a secondary metal or doping heteroatoms into the support. This dissertation covers the rational design, synthesis, and stabilization of Pt-based catalysts in these two ways to achieve durable catalytic performance with desired activity and selectivity. …

Gonorrhea: Core Areas And State Policies, Jessica Purser

Theses and Dissertations

This research looked at gonorrhea rates both from a community perspective and at the state level. Using hot spot analysis, means differences, and quantile regression, we found that education, specifically the percent of people over the age of 25 with less than a high school education, was the dominant factor at the state level while core areas of gonorrhea exist in the PeeDee and western Lowcountry regions of South Carolina in 2017 and 2018. Risky sexual behaviors are well-defined in the literature for individual persons, but this shows that looking at societal and community factors is important.

This is a …

First-Principles Based Heterogeneous Catalyst Design For Energy Conversion And Plastics Upcycling Processes, Kyung-Eun You

Theses and Dissertations

Replacing scarce and expensive Pt-group metals (Pt, Pd, Ir, Rh, and Ru) commonly used in heterogeneous catalysis with earth-abundant and inexpensive materials is an important challenge to achieve sustainability

The main focus of the first project is to develop highly selective non-precious metal catalysts for the hydrodeoxygenation (HDO) of biomass-derived polyols and we chose to examine the HDO of glycerol and its deoxygenated reaction products (1,2- and 1,3- propanediol) over Cu modified Mo₂C (Cu/Mo₂C) catalysts. In this study, we combined experimental and density functional theory (DFT) results to reveal that the Cu modifier can significantly reduce …

Trajectories And Psychiatric Consequences Of Inhibitory Control In Young Males With Fragile X Syndrome, Erin Hunt

Theses and Dissertations

Inhibitory control (IC), the ability to suppress inappropriate responses, emerges late in the first year of life and improves across typical development, concurrent with brain maturation. The development of IC is critical to various social-emotional and behavioral functions, with IC deficits being linked to numerous psychiatric conditions, including attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Fragile X syndrome (FXS) is a single-gene disorder characterized by IC deficits, and elevated rates of ADHD and ASD, making it a useful model for understanding the early development and consequences of IC. In this longitudinal study, we characterized IC trajectories across multiple time …

Associations Of The Fto Gene And Risk Of Acute Myeloid Leukemia, Avery Ulrich

Theses and Dissertations

Background Acute Myeloid Leukemia (AML) is a blood cancer that affects ~70,000 people each year in the US. The Fat Mass and Obesity (FTO) gene on chromosome 16 has been reported to be associated with obesity, solid tumor cancers (lung, renal, breast, prostate, pancreatic, endometrial), and more recently with hematologic malignancies, like AML. In this thesis, we test the hypothesis that inherited variants within the FTO gene are associated with an increased risk of AML. Methods Using the DISCOVeRY-BMT (Determining the Influence of Susceptibility COnveying Variants Related to one-Year mortality after Blood and Marrow Transplantation), a well-powered genome-wide association study …

American Fury: Catholic Responses To Spanish Anticlericalism (1936-1939), Paul Sanders Linker Jr.

Senior Theses

This thesis examines the roles, ideologies, attitudes, and arguments of American Catholics in debates over the Spanish Civil War from 1936-1939. Although the war only lasted between these years, these debates carried over into WWII as Spain’s neutrality came into question. Specifically, the focus is on how American Catholics grappled with historically unprecedented Spanish anticlericalism, the direct murder of roughly 7000 Catholic clergy and persecution of many more by Spanish Republicans, and why this anticlericalism drove most Catholics into a form of unapologetic pro-Francoism. This research is conducted by careful analysis of both mainstream and Catholic newspapers/journals. Mainstream pro-Republican press …

From An Ambivert's Perspective: The Relationships Between Personality Types, Attachment Styles, And Behavioral Tendencies Of Introverts And Extroverts, Andrew Chang

Senior Theses

Over the years, there has been continuous discussion around the idea that extroverts dominate the business workplace over introverts and vice versa. However, depending on the work setting and skillsets needed, it is imperative to realize how certain business practices, personality styles, and relationship approaches are different in every scenario. For this research thesis, the goal was to compare the personality and attachment styles of students who study in two different cultural environments, seeing if there were any apparent relationships between the two variables and student behavioral tendencies. Previous studies have shown that personality, behaviors, and attachment levels can predict …

Which Motivations Impact The Relation Between Adhd Symptoms And Simultaneous Use Of Alcohol And Marijuana?, Caroline Hough

Senior Theses

Attention-deficit/hyperactivity disorder (ADHD) symptoms are associated with greater risk for substance use and abuse. About one in four adults with ADHD has a comorbid substance use disorder. Polysubstance use, or mixing multiple drugs, is becoming increasingly prevalent on college campuses. The simultaneous use of alcohol and marijuana (SAM) is a particular polysubstance use pattern that is significantly correlated with more risky behaviors (e.g., reckless driving, unprotected sex) and adverse consequences (e.g., blackouts, physical injury) than using one substance alone. An estimated 15% of 18- to 29-year-olds engage in SAM each year, while recorded rates of SAM in college students are …

The Aftereffects Of Corporal Punishment On Adults: Association Of Childhood Spanking With Adult Stress Levels, Marie Sanyang

Senior Theses

Spanking has been an acceptable form of punishment for centuries. Previously thought as effective, studies have now shown the detriments of spanking, including increased aggression, drug abuse, and stress levels. This exploratory study sought to observe the stress levels of adults who experienced childhood spankings. It was hypothesized that those who experienced frequent spankings would report increased anxiety, reduced socialization, and decreased emotional regulation in times of stress. It was also hypothesized that those who reported being spanked would report lower emotional and physical health regulation and higher mental health diagnosis. Fifty-four participants were composed of undergraduate and graduate students …

Determining The Role Of High-Sugar Diets On Ovarian Function In Drosophila Melanogaster, Emma Otey

Senior Theses

The prevalence of obesity in the United States has increased drastically and the effects of obesity on human physiology are not fully known at this point. It has been noted that there is a significant decrease of fertility rates in obese women. In order to study how exactly these high-sugar or high-fat diets are impacting fertility, Drosophila can be used as a model organism. The use of Drosophila as a model organism for humans is due to the many conserved molecular and systematic mechanisms, namely ovarian function, as well as conserved physiological responses to obesity and obesogenic diets. This study …

A Problem-Based Learning Approach To Civics Education: Exploring Citizenship Through Authentic Scenarios In A Middle School Civics Classroom, Rebekah Meri Rowland

Theses and Dissertations

This dissertation focuses on implementing problem-based learning as an instructional intervention in a middle school civics classroom. This action research study responds to the observations of the teacher-researcher who noticed that her students were not make meaningful connections to the practice of citizenship. The problem of practice was developed when the teacher-researcher realized that the students were not engaged in learning with the traditional lecture-style, rote memorization instruction; she needed an intervention that was active, collaborative, and meaningful. To increase the connection to middle school learners, the intervention should emphasize problem solving skills and build empathy for others through a …

The Effects Of Ionizing Radiation On Domestic Dogs: Ancestry And Genetic Structure Of Free-Roaming Dog Populations In Chernobyl, Ukraine, Gabriella Jean Spatola

Theses and Dissertations

This thesis is concerned with the effects of ionizing radiation on domestic dogs (Canis lupus familiaris) which were commonly used as laboratory subjects during the era of atomic bomb testing (1950s - 1980s). Early laboratory studies on radiation effects in dogs provided important foundations of knowledge for research that has more recently shifted to natural populations exposed to ionizing radiation from nuclear accidents. A unique group of free-roaming dogs reside in an environment polluted by radioactive contamination deposited during the Chernobyl nuclear disaster of 1986, providing one such opportunity to study the effects of ionizing radiation on dogs …

The role of antibiotics in human health is of significant importance in the advancement of the medical field. It has contributed to an improvement of the quality of life and the age expectancy of the population. Antibiotic resistance is an expected consequence of the use of antibiotics. Bacteria have developed biological mechanisms that would help them become resistant to antibiotics. The uncontrolled use of antibiotics is significantly contributing to the ability of bacteria to become resistant to those antibiotics. This study, using the model of the Socio-Ecological Coupling of Antibiotic Resistance, explains how social and environmental factors interact and impact …

Possible Studies On Generalized Parton Distributions And Gravitational Form Factors In Neutrino Reactions, Shunzo Kumano, Roberto Petti

Faculty Publications

Spacelike and timelike generalized parton distributions (GPDs) have been investigated in charged-lepton scattering and electron-positron collisions via deeply virtual Compton scattering and two-photon processes, respectively. Furthermore, we expect that hadron-accelerator-facility measurements will be performed in future. The GPDs will play a crucial role in clarifying the origins of hadron spins and masses in terms of quarks and gluons. It is also possible to probe internal pressure within hadrons for understanding their stability. Gravitational form factors of hadrons used to be considered as a purely academic subject because gravitational interactions are too weak to be measured in microscopic systems. However, due …

Walla, Shi-Hui Dong, Xiaoyu Tang, Hexin Chen, Prakash Nagarkatti, Mitzi Nagarkatti, Yong-Xin Li, Jie Li

Faculty Publications

Bacterial natural product biosynthetic genes, canonically clustered, have been increasingly found to rely on hidden enzymes encoded elsewhere in the genome for completion of biosynthesis. The study and application of lanthipeptides are frequently hindered by unclustered protease genes required for final maturation. Here, we establish a global correlation network bridging the gap between lanthipeptide precursors and hidden proteases. Applying our analysis to 161,954 bacterial genomes, we establish 5209 correlations between precursors and hidden proteases, with 91 prioritized. We use network predictions and co-expression analysis to reveal a previously missing protease for the maturation of class I lanthipeptide paenilan. We further …
