Manipulation Or Monetization?: The Rise Of Stock Buybacks And Their Effects On Firm Valuation And Investment, Thomas H. Serrano

Economics Undergraduate Honors Theses

Abstract:

This thesis uses basic econometrics to examine the relationship between stock buybacks, firm valuation, and investment among publicly traded firms from 2000-2024. Using firm-level data pulled from Compustat North America and a fixed-effect multivariate regression, it evaluates whether buybacks are associated with higher valuation and stronger productive investment as defined in the paper. The results show that buybacks are positively associated with firm valuation the first year that they occur, but the relationship disappears when they are lagged for a year. Furthermore, the analysis does not find strong statistical evidence that repurchases are associated with changes in investment, or …

Exploring The Training Experiences Of Adult Taekwondo Practitioners: A Case Study Of A Martial Arts Program In The Southern United States, Nicholas Daniel Ryburn

Graduate Theses and Dissertations

Taekwondo has gained increasing prominence among adult practitioners in the United States, offering both physical and psychological benefits. However, despite its popularity, research on Taekwondo has predominantly emphasized youth populations, competitive contexts, or injury epidemiology, with limited attention to the lived experiences of adult practitioners. Adults present distinct needs and challenges in martial arts training, including variability in physical conditioning, age-related health considerations, and constraints associated with family and professional responsibilities. A deeper understanding of these factors is crucial for developing training programs that are both effective and sustainable for adult populations. This dissertation employs a qualitative case study design …

Across The Pond And Veil: Spiritualists, Female Mediums, And Ghosts In The Nineteenth-Century United States And Britain, Allison Tucker

Graduate Theses and Dissertations

This thesis examines how women mediums in the late nineteenth-century United States and Britain shaped Spiritualism and interpreted their respective social landscapes. Spiritualist mediums claimed the ability to communicate with spirits in the spirit world. These conversations with ghosts allowed mediums to speak on recent events, traverse social boundaries, and assume positions of authority. Drawing on trance writings, spirit-authored books, newspaper articles, and the performances of women mediums, this study compares the development and practices of Spiritualism in both countries. This thesis argues that proximity to violence significantly shaped Spiritualism during its formative years. The Civil War placed Americans in …

Of Dunes And Ice: A Surface-Atmosphere Investigation Of Mars Co2 Sublimation Features And Titan Aeolian Fields, Racine D. Cleveland

Graduate Theses and Dissertations

This dissertation investigates a central question: How do planetary boundary layer processes manifest in observable surface geomorphology, and how can planetary imagery be used to quantify those effects? The planetary boundary layer (PBL) governs near-surface exchanges of momentum, heat, and volatiles, yet direct atmospheric measurements remain spatially and temporally limited on most planetary bodies. By analyzing geomorphic features preserved in high-resolution imagery, this work quantifies how boundary-layer processes leave measurable signatures on planetary surfaces. For Mars, high-resolution images from the Mars Reconnaissance Orbiter (MRO) HiRISE instrument were used to map CO2 sublimation features, or Swiss Cheese Features (SCFs), on the …

Graduate Theses and Dissertations

The slow degradation of natural resources has resulted in the focus of agriculture shifting towards conservation practices, such as reduced/no-tillage, cover crops (CC), and organic amendments (i.e., biochar), that conserve and improve natural resource quality. The objectives of this thesis were to i) quantify the impacts of biochar rate (i.e., 0, 2000, and 4000 kg ha-1) and ii) the combination of CC and tillage practice on carbon dioxide (CO¬2), methane (CH4), and nitrous oxide (N2O) fluxes, growing-season-long emissions, global warming potential (GWP), soil properties, and plant response from a minimally tilled cotton (Gossypium hirsutum)-corn (Zea mays) rotation and a soybean …

Impacts Of Climate-Smart Agriculture On Greenhouse Gas Emissions In Southeast Arkansas Cotton, Cassandra Seuferling

Graduate Theses and Dissertations

Increasing concerns of climate change have led to the evaluation of greenhouse gas (GHG) emissions [i.e., carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)] from agroecosystems, particularly cotton (Gossypium hirsutum) production. Technology improvement and conservation agriculture methods [i.e., reduced-tillage (RT) instead of conventional tillage (CT) and the use of cover crops (CC)] require further evaluation regarding GHG emissions from Arkansas cotton production. The first objective of the study was to evaluate four gas-flux-determination methods [i.e., linear or exponential regression models, with negative fluxes (WNF) included in the dataset or replacing negative fluxes (RNF)] on CO2, CH4, and N2O fluxes …

Searching Harder For The Darter: Evaluating Endangered Yellowcheek Darter (Nothonotus Moorei) Status And Drought Responses, Kearstin Findley

Graduate Theses and Dissertations

Freshwater ecosystems are one of the most imperiled habitats across the world with biodiversity declining rapidly. There are many stressors contributing to freshwater species declines including habitat loss and degradation, land-use changes, anthropogenic water demands, changes in precipitation and weather extremes, and pollution. Current environmental projections predict that these stressors will continue to impact freshwater ecosystems to greater extents moving forward. Stream drying from drought conditions increasing in intensity and frequency is especially concerning in northern Arkansas where seasonal drought is typical in the summer and fall months. With increased drying conditions, the elimination of shallow-water riffle habitats in streams …

Initial studies focused on optimizing viral delivery methods using Tulane virus …

Situational Determinants Of Severity In Bias-Motivated Violence, Sophia Glick

Graduate Theses and Dissertations

Although overall violent crime rates continue to decline, bias-motivated violence, including bias murder, is rising in the United States (United States Department of Justice, 2024). Criminologists have examined how situational factors—such as location, weapon use, and bystander presence—increase the likelihood of violence escalating to murder. However, it remains unclear whether these same factors similarly affect the severity of bias-motivated violence. These gaps are notable given that prior research suggests bias-motivated violence differs situationally from other forms of violence. Guided by the situational crime prevention (SCP) perspective, the current study investigates how situated attributes of factors reflecting the vulnerability and symbolic …

Proud To Be Lao: Examining Lao American Identity Through Transnational Music And Performance, Zechary Phouthavong

Graduate Theses and Dissertations

For some time, Lao popular music has not received the same global recognition as other genres emerging out of Asia, such as K-Pop and Bollywood.

Writing Through The Plague: Memory, Trauma, And Survival In Arabic And English Narrative, Zainab Abbood Jawhar Aldaoseri

Graduate Theses and Dissertations

This thesis examines how Arabic and English literary and intellectual traditions responded to the Black Death as a shared yet differently articulated experience of collective trauma. Drawing on trauma theory, particularly the work of Cathy Caruth and Dominick LaCapra, it analyzes how plague narratives function as cultural mechanisms for processing mass suffering. Through a comparative study of Arabic historiographical, theological, medical, and poetic texts alongside English allegorical, mystical, autobiographical, and satirical writings, this project argues that both traditions developed distinct narrative strategies to render the trauma of plague intelligible. Arabic plague literature, represented by figures such as Ibn Khaldūn, Ibn …

Characterization Of Snrk1 Signaling In Rice Growth, Reproduction, And Stress Responses Using Phenotypic And Omics Analysis, Maria Clara Faria-Bates

Graduate Theses and Dissertations

SnRK1 is an evolutionarily conserved protein kinase belonging to the SNF1/AMPK family that is composed of a catalytic subunit (α) and two regulatory subunits (β and βγ), and it has a major role in adjusting growth in response to the energy status. SnRK1 phosphorylates and alters the activities of enzymes involved in metabolism and regulates gene expression by altering the activity of chromatin-remodeling enzymes or transcription factors. Rice contains three functional paralogs of SnRK1α: OsSnRK1αA (Os05g0530500), OsSnRK1αB (Os8g0484600), and OsSnRK1αC (Os03g0289100). Although SnRK1 is known to play a central role in plant growth and stress responses, the functional specialization of …

Grazed Pasture Effects On Greenhouse Gas Emissions In The Ozark Highlands, Tyler Buchanan

Graduate Theses and Dissertations

In the United States (US), grazinglands serve as the main foundation for the livestock industry, and, in Arkansas specifically, pastures are essential for rotational grazing and dairy operations. Climate change is increasingly becoming a concern in the agriculture industry, largely caused by anthropogenic activities increasing greenhouse gas (GHG) concentrations in the atmosphere, at least partly due to the nutrient recycling that occurs from animal manure additions in grazinglands. Therefore, quantifying GHG emissions from pastures is essential to better understanding the impacts of grazing on the environment. The objective of this study was to quantify and evaluate the potential effects of …

Misusing Mariátegui: The Strategic Use Of José Carlos Mariátegui By Peru’S Sendero Luminoso, Shaylee Luedders

Graduate Theses and Dissertations

The Peruvian Communist Party - Sendero Luminoso (SL) was a violent communist guerrilla group that was active in Peru in the 1980s and early 1990s. SL’s guiding ideology was “Gonzalo Thought,” named for the Party’s leader, Abimael Guzmán, who was known to his followers as Presidente Gonzalo. Greatly inspired by Marxism-Leninism-Maoism, Gonzalo Thought also drew heavily from the work of José Carlos Mariátegui, an early 20th-century socialist Peruvian intellectual. One of Mariategui’s key ideas held that the Inca Empire was communist and that living Indigenous Peruvians retained this pre-modern “communist spirit.” For him, this meant that authentic Peruvian institutions and …

The Line In The Sand: Visual Narratives Of Religious Trauma And Leaving Evangelicalism, Elizabeth Humphrey

Graduate Theses and Dissertations

Widespread abuse within religious institutions has challenged the assumption that religion inherently supports mental health, while rising rates of religious disaffiliation often cite trauma as a key factor. Individuals leaving harmful religious environments report a range of outcomes—from increased autonomy to emotional distress—yet research on post-disaffiliation experiences is limited. As the religious landscape of the U.S. shows decrease in religious affiliation, and stories of abuse and trauma circulate, the experience of leaving a religious community because of harm is a needed area for further inquiry. Using visual narrative inquiry, this qualitative research study explores the lived experiences of those who …

Bats And Bacteria: Infection Dynamics At The Human-Wildlife Interface, Isabella Katherine Deanglis

Graduate Theses and Dissertations

As the second most diverse mammalian order, bats host an array of pathogens, some of which are known to infect humans. Synanthropic bats share spaces with humans, resulting in bat-borne pathogen exposure. While most bat-borne disease research has focused on viral pathogens, bats host numerous bacterial pathogens with zoonotic potential. By integrating a global meta-analysis with field studies in Sub-Saharan Africa, I characterize the structural attributes that facilitate shared interfaces, the bacterial pathogens present in synanthropic bats of rural Kenya, and the physiological and environmental dynamics influencing odds of infection in these synanthropic bats. Finally, I evaluate the clinical relevance …
