Mindset, Stereotype Threat, And The Fear Of Failure: Why Female Students Leave A Secondary High Honors Mathematics Pathway, Annabelle Merg

Theses and Dissertations

The disproportionate attrition of female students in STEM is well documented in higher education but less well understood at the secondary level. In a large, public high school in an affluent, highly educated city, the high honors mathematics pathway is the only math pathway that has not yet achieved gender parity, an implication for future educational and economic equity. Female students leave this pathway at significantly higher rates than male students, especially during and immediately after the first course. Through an explanatory, mixed methods approach, this study found that these female students are not less well prepared than their male …

An Analysis Of Wet Bulb Globe Temperature Estimation Methods And Microclimate Heat Variability In Columbia, South Carolina, Stafford Mullin

Theses and Dissertations

Extreme heat is the leading cause of weather-related deaths in the United States and poses major health risks in the wake of rising global average temperatures. Wet bulb globe temperature (WBGT) is a holistic measure of human heat stress, but is not feasible to implement in most settings because the equipment is expensive and troublesome to operate. This research evaluates the performance of WBGT estimation methods using more standard meteorological variables, measured in-situ and a local National Weather Service Automated Surface Observing Station, and examines how WBGT and its components vary across two distinct microclimates in Columbia, SC. Results indicate …

Understanding The Genomic Influence And Virulence Capabilities Of Environmentally Isolated Vibrios, Shannon Elizabeth Pipes

Theses and Dissertations

The genus Vibrio consists of Gram-negative bacteria that possess a curved rod shape and are routinely isolated from estuarine and coastal salt water. Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus are the major three species that contribute to human disease worldwide, and a variety of other Vibrio species contribute to persistent problems in the aquaculture and fishing industries. The CDC estimates that vibrios cause 80,000 cases of disease each year in the United States alone, however, this number is thought to be underestimated, since some disease is only self-limiting, meaning patients may not seek medical treatment and have …

Predicting Lower Body Soft Tissue Injuries In American Football With Gps Data, Nicholas Tice

Theses and Dissertations

It is of utmost importance to sports organizations that they keep their players as healthy as possible and contributing to the success of the team. Advancements in technology and investments by sports clubs have allowed researchers to better understand the role of load management in high-level athletes to mitigate injury risk. Through GPS tracking data provided by a collaborating Division I American college football team, we seek to predict lower body soft tissue injuries in future training sessions and reduce the number of potentially avoidable injuries within the organization. The difficulty of analyzing the injury data set is that the …

Sex (Work) And The City: Sex Work In Columbia, South Carolina, 1860-1880, Presley Mckalyn Ramey

Theses and Dissertations

Nineteenth-century sex work in the American south has long been neglected in sex work historiography. Formerly Confederate states have red-light districts rich in history, and stories of the South waiting to be told. The city of Columbia has great significance as the capital of the first southern state to secede from the Union, and this thesis acts as a local history of the city’s red-light district. Utilizing city ordinances, court cases, census records, city directories, probate records, and wills, the lives of Columbia’s sex workers and how they interacted with the growing city around them are brought to the forefront. …

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 …

S-Equol: A Novel Therapeutic For Hiv-1 Induced Gut Dysbiosis, Mason T. Rodriguez

Theses and Dissertations

HIV-1 infection affects approximately 38 million people around the world. The advent of cART has greatly improved the quality of life of infected individuals; however, roughly 50% of these individuals will still experience HIV-1 associated neurocognitive disorders (HAND). Additionally, the gut microbiome has been reported to be dysbiotic in HIV-1 infected individuals, regardless of adherence to cART. Current research has pointed to the gut-brain-microbiota axis as a potential target to treat both cognitive deficits and microbial changes. The present study investigated S-equol (SE) as a potential therapeutic for HAND by modulating the gut microbiome. The study included 21 HIV-1 Tg …

Theses and Dissertations

This dissertation includes three essays on behavioral economics with applications in health, strategic thinking, and labor.In the first essay titled ``The Effect of Nudging on the Utilization of Counseling Services and the Implications on College Student Involvement'', I examine the effect of nudging on the utilization of mental health services and the impact on college student involvement. To improve the utilization of mental health services for college students I designed and implemented an intervention promoting a pro-counseling social norm on campus. More specifically I sent campus-wide emails to inform students of the mental health services offered on campus. Randomly selected …

Mining For Progress: Copper, Conflict, And Corporate Social Responsibility, Fritz Culp

Theses and Dissertations

My dissertation examines how transnational mega-mines efface non-Western ways of knowing and being from the Andes. A growing branch of research is questioning the socio-environmental impacts of mining and the influence of regulatory institutions. Despite remarkable scholarship on the ongoing environmentalism of modern-mining, little critical attention has been given to the industry’s pivot to ‘sustainable’ development and its objectives that remain epistemologically centered on the West. My project addresses these gaps by examining Las Bambas—a large-scale copper mine located in South-Central Peru—and its contrasting objectives that emphasize both environmental ‘conservation’ and the ‘modernization’ of non-Western spaces. Building upon the critical …

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 …

The Impact Of Cannabis And Alcohol Use On The Management Of Type 1 Diabetes Mellitus, Joshua Eric Sellner

Theses and Dissertations

This dissertation sought to contribute to the evidence-base of diabetes management and acute complications associated with alcohol and cannabis use among individuals with Type 1 Diabetes (T1DM). Three interconnected studies were initiated to complete this goal. First, existing literature surrounding the potential consequences of cannabis consumption among individuals with T1DM were summarized within a systematic review. Study results were combined to provide a single measure of association through a meta-analysis. Second, identified associations were further investigated through a cross-sectional study using the SEARCH for Diabetes in Youth data on alcohol and cannabis use on diabetes management and acute complications including …

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 …

Interrogating Rosa Montero’S Transition To Consensus: The Literary Interview As Lieu De Mémoire, Adrienne D. Banko

Theses and Dissertations

Looking from our 21st century viewpoint, the collection of interviews España para ti…para siempre (1976) and Cinco años de País (1982) can be seen as artifacts of the Spanish Transition to democracy and should be regarded as collections of “places of memory.” Many scholars chronicling the Transition and its impacts have positioned Rosa Montero as a prominent feminist writer of the period. However, her journalistic writing demonstrates her mediatic role as linchpin between the social and political transitions interwoven into the foundation of Spain’s democratic emergence from Francoism. These works were published at a particular moment of consensus in …

Functional Analysis Of Stn1 Winged-Helix (Wh) Domains, Anna Bazell

Senior Theses

CST (CTC1-STN1-TEN1) is a heterotrimeric RPA-like protein complex that preferentially binds to single-stranded DNA (ssDNA). CST is conserved from yeast to humans and has been found to play a role in telomere maintenance, DNA replication, and DNA repair. Mutations in CST, specifically in the subunits of CTC1 and STN1, have been implicated in the development of the genetic diseases Coats plus and dyskeratosis congenita. Despite the known functions of CST, the mechanistic relationship between its structure and function has yet to be characterized, particularly with respect to its protein-protein interactions and DNA binding. An X-ray crystallography structure of CST revealed …

Birth Outcomes For Hispanic Women In South Carolina, Reilly Leaver

Senior Theses

The United States maintains disproportionately high infant mortality rates compared to other developed countries globally (Arima et al., 2009). High barriers to accessing affordable reproductive health care are key drivers behind this phenomenon, with minority ethnic and racial populations in the Deep South region of the United States facing these barriers at much higher rates than their white counterparts (Davis et al., 2020). Factors such as low levels of education, low use of private health insurance, and low participation in prenatal care generally correlate with adverse birth outcomes. Both Hispanic and Black mothers experience these factors at similarly low levels, …

The Impact Of Plant Cell Wall Lignin On Energy Utilization In Lactating Jersey Cows, Jason D. Stypinski

Department of Animal Science: Dissertations, Theses, and Student Research

Fiber from forages comprises a significant proportion of dairy cattle rations and by extension, it contributes largely to the energy concentration of the diet. While the proportion of fiber in the diet is important, the composition of fiber is probably more important as the different constituents of this fraction vary in their contributions to the nutritive value of the feed. Lignin has been described as an important factor limiting the digestion of NDF, reducing intake, and compromising milk production. Although lignin’s effects on these responses have been well characterized, the literature lacks data on the use of indirect calorimetry to …

Annotating Gene Expression And Regulatory Elements In Tissues From Healthy Thoroughbred Horses And Identifying Candidate Mutations Associated With Perosomus Elumbis In An Angus Calf, Alexa Mckenna Barber

Department of Animal Science: Dissertations, Theses, and Student Research

Genome annotation has a direct impact on the success of genomic studies. Transcriptome analyses and chromatin immunoprecipitation and sequencing (ChIP-seq) have been used to functionally annotate genomes. These methods can identify protein-coding genes, non-coding transcripts, and cis-regulatory elements across the genome. The primary objective of the first study was to functionally annotate the equine genome through the assessment of nine tissues: adipose, brain, heart, lamina, liver, lung, skeletal, muscle, testis, and ovary. In the first project, 150 bp, paired-end RNA sequencing (RNA-seq) libraries were generated in stallion tissues and compared to previously generated mare RNA-seq libraries to quantify variation in …

Accelerating Peripheral Nerve Regeneration Using Electrical Stimulation Of Selected Power Spectral Densities, Wei-Ming Yu, Madelyn Mccullen, Vincent Chiun-Fan Chen

Biology: Faculty Publications and Other Works

Peripheral nerve injuries are common consequences of extremity trauma or chronic compression with a prevalence of 43.8 per 1 million people (on average) reported in the United States annually, accompanied by a yearly increase in cost of care. Patients suffering from these injuries require surgical procedures and rehabilitative strategies to reinforce their extensive recovery. Several studies have found that the application of electrical stimulation can accelerate peripheral nerve regeneration, thus shortening the time of peripheral nerve growth and reducing the cost of care (Willand et al., 2016). The electrical stimulation paradigms that effectively enhanced functional recovery in most studies employed …

Nourishing The Extra-Ordinary Minister, Amante Pulido

LMU Theses and Dissertations

The lay minister of the Eucharist often is a generous volunteer of his or her time, and who is gladly accepted and commissioned by the parish. But the call to ministry comes from two main sources: a “call” from an interior desire to serve sometimes in any capacity but mostly to serve specifically in a particular ministry like the Extraordinary Minister of the Eucharist; another is a “call” from the pulpit when ministries launch appeals for membership among the laity for the different ministries that are wanting of membership, mainly for volunteers. After signing up there would then be the …

Eco Yoga Therapy For Mental Health Related To The Covid-19 Pandemic, Karyn Stein

LMU Theses and Dissertations

Recently the magnitude of the mental health crisis due to the COVID-19 pandemic has been emerging. Reports of anxiety or depression related to COVID-19 have been on the rise globally. Individuals have been living in a perpetual state of the unknown for over two years. Fear of the virus, sickness of oneself or family/friends and social isolation have taken a toll. According to the WHO, anxiety and depression have gone up 25% in the last year (2022). The effects of a rising mental health crisis will be drastic on top of the deaths and sickness related to COVID-19. While governments …

Sex Addiction: A Literary And Yogic Perspective, Adrienne Hope Hite

LMU Theses and Dissertations

First offering insight into the disease of sexual addiction overall and what, in fact, does delineate it from sexual promiscuity, this paper will go on to seek ways to mitigate such behavior by exploring not only symptoms, but the existing underlying issues as well through a yogic whole-body perspective. Furthermore, diving deeper into such an application, specifically under the context of the yamas and niyamas and investigating how both might, not only serve as therapeutic tools for sex addicts, but perhaps allow for a healthier approach overall to sex in the modern world.

First offering insight into the disease of …

In Search Of Divine Liberated Love: A Yoga Memoir, Katie D. Davidson

LMU Theses and Dissertations

I opted to write a memoir about my personal experiences in yoga, rather than a traditional research-based thesis. A key distinction between memoir and autobiography or auto-ethnography is that it’s not linear—much like my yoga journey. Often, experiences, particularly around healing emotional trauma, are more circular in nature, perhaps even more of a spiral. According to Carl Jung, “The spiral in psychology means that when you make a spiral you always come over the same point where you have been before, but never really the same, it is above or below, inside, outside, so it means growth.” (Jung 5, p. …

Accompaniment In Times Of Suffering: Liberating Images Of God, Carmen Ramos Carmona

LMU Theses and Dissertations

Atonement theologies of salvation are problematic for suffering victims, which calls for a change in how we imagine God and view salvation today. A distorted image of God and God's salvation deprives those in distress of finding consolation, healing, and agency through their faith. I apply a feminist critical hermeneutic of liberation that reveals that the application of CDH can accommodate violence and other forms of evil against the marginalized, women, and the natural world. It is necessary to find metaphors for God that can offer spiritual sustenance to those who suffer and reimagine an alternate idea of God's salvation. …

Lamentations For Liberation: A Theological Analysis Of The Miseducation Of Lauryn Hill, Sophia Gilmour

LMU Theses and Dissertations

While exploring the history of liberation theology themes appearing in Black musician’s work (in Dr. Daniel Smith-Christopher’s class Bible and the Blues), it came to my attention that there are many more contemporary artists whose work also touches on these themes, such as Lauryn Hill. My thesis argues with the help of Black and Womanist scholars that the naming of one’s reality through musical lamentations is a healing act. Further, musical lamentation is an act to carry forth communities and provide them with healing because the act of acknowledging and lamenting the suffering of a marginalized community is liberating in …

Determinants Of Hiv Treatment Disparities In The Latino Population Of South Carolina, Elizabeth G. Caulk

Senior Theses

The Latino population in the United States faces a heightened risk in terms of contracting HIV/AIDS and experiencing negative health outcomes from said infection. HIV/AIDS continues to disproportionately impact ethnic/racial minorities, and the Latino population exemplifies this unfortunate trend, with Latino Americans making up around 18.4% of the national population, but nearly 30% of the HIV/AIDS infections (US Office of Minority Health, 2021). More enduring changes to the current resources available to this population will need to be made in order to address this disparity. Thus, the current study examined social determinants, how they increase risk of infection, and how …

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 …

Assessing Satisfaction With Bi-Weekly Produce Deliveries As A Means To Reduce Food Insecurity On College Campuses, Sophie Crosby

Senior Theses

Background: As food insecurity disproportionately affects college students and students are often unable to receive government nutritional assistance, more lasting, sustainable interventions are needed to decrease food insecurity on college campuses. The purpose of this study was to measure the satisfaction of the FoodShare program, a low-cost, biweekly fresh produce delivery, at the University of South Carolina. The purpose of this study was to pilot FoodShare’s program with adaptations to the University of South Carolina and examine participants’ experience with the program. Methods: Forty-three students, faculty, and staff purchased boxes over a three-month period. FoodShare boxes were purchased and delivered …
