Exploring Undergraduate Student’S Perceptions Of Agriculture, Cayden J. Barton

Honors Theses

Americans today, both young and old, face issues with agricultural knowledge regarding the food and fiber industry and production agriculture as a whole (Frick et al., 1995). In a society where consumers are separated from production agriculture, public interaction with agriculture is less prevalent and the importance of agriculture is undervalued. A person’s knowledge of agriculture, or agricultural literacy affects the way that they perceive agricultural commodities and the agricultural industry (Specht, McKim, & Rutherford, 2014). Without adequate knowledge of the agricultural industry consumers cannot make well informed decisions about food safety or processing methods. In addition to consumers, government …

Empowering Futures: Inspiring Young Girls In Stem Through Comics, Angel M. Griggs

Honors Theses

Women have historically been underrepresented in STEM fields. In my analysis, I explored how children’s literature representing historical women role models empower young girls to possibly pursue STEM careers. I applied Vekiri’s et. al (2024) research on attracting girls to STEM through interactive video games displaying STEM role models to comic books. In this project, I review academic literature, historical sources, and research articles to develop an educational comic book about historical women in STEM to help support the idea that creative activities and resources displaying role models can be influential to young children, specifically young girls. I focused on …

The Impact Of Sex Education On College Student’S Perceptions Of Sexual Taboos, Noel Gamon

Honors Theses

The purpose of this research is to explore how college students' differing levels of sex education are associated with their views about sexual behavior, particularly behaviors defined as taboo. In comparison to 25 years ago, adolescents are less likely to receive important sex education today; and are unlikely to receive valuable information until after their first sexual experience. Conventionally, the benefits of a sex education program are linked with its ability to lower STI rates, unplanned pregnancies, unwanted behavior, etc. Sexual taboos are sexual practices excluded from the hegemonic heterosexual monogamous relationship model. Presently, society acknowledges a wider range of …

G1p3 Dysregulates Interferon-Stimulated Gene Expression In Er (+) Breast Cancer Cells, Karina Santana

Honors Theses

Even with advances in diagnosis and treatment, breast cancer remains the second leading cause of cancer-related death in women, with nearly 90% of fatalities linked to drug resistance driven by metastasis and recurrence. G1P3, an anti-apoptotic mitochondrial protein, is upregulated in breast cancer and has been associated with increased metastatic potential and poor prognosis. Recent findings show that G1P3 enhances interactions between Rab5-containing endosomes (RCEs) and mitochondria, and emerging evidence suggests that mitochondria play a critical role in initiating interferon (IFN) responses. Based on this, we hypothesized that G1P3-mediated interactions between RCEs and mitochondria promote interferon-stimulated gene (ISG) expression in …

Behind The Scenes: An Examination Of The Realities, Misconceptions, And Practices Of Graphic Design, Abby Harris

Honors Theses

Graphic design is an often-misunderstood field of work, generally understood through its outcomes, such as logos, posters, and digital interfaces. However, the extensive creative and strategic processes behind these projects remain largely unseen and unappreciated. While it is not a STEM or medical discipline, graphic design is still a rigorous field in its own right. However, people generally consider a degree in graphic design as easy or a waste of time because they view the arts as hobbies. The public only ever sees the finished visuals, not the labor, thinking, and countless hours of revision behind them. The growing wave …

Exploring The Synthesis, Characterization, And Aggregation Properties Of Perylene Diimide Derivatives, Erica Salinas

Honors Theses

Once widely used for its vivid presence in an array of industrial dyes, perylene-3, 4, 9, 10-tetracarboxylic dianhydride (PTCDA) is a known precursor for perylene diimides (PDIs). These compounds are an alternative for sustainable energy within organic solar cells (OSCs) and for improving organic light emitting diodes (OLEDs). PDIs are a great candidate for organic semiconductor applications because of their overall flexibility and low manufacturing cost as an organic photovoltaic. Its extended π-conjugation results in a planar structure promoting strong π- π intermolecular stacking, giving aggregated PDIs high electron mobility, allowing a flow of electrons to move through these stacked …

Nutrition has a significant impact on athletic performance and the development in an athlete’s specialty. To assess the current knowledge of athletes, the track athletes of East Texas A&M University were asked to participate in a nutritional assessment to determine their knowledge of nutrition in regard to their sport. It was hypothesized that the majority of athletes surveyed would not possess adequate knowledge …

Essays In Macroeconomics, Sihyun Kim

Arts & Sciences Graduate Student Theses and Dissertations

The dissertation consists of two research projects in macroeconomics. The first chapter studies a topic in fiscal policy and sovereign debt. I became interested in this topic during my third year of the Ph.D. program while working as a research assistant for Professor Manuelli. He recommended several papers on debt sustainability in the U.S. and Japan. I initially struggled to reconcile the coexistence of low default risk and persistent fiscal deficits in these countries. This led me to think that, in addition to the realized fiscal path, the fiscal capacity---such as the tax base---can also play an important role in …

Space-Time Coded Pcm/Fm For Aeronautical Mobile Telemetry, Zachary B. Hilton

Theses and Dissertations

This thesis describes the application of a space-time block code for the legacy continuous phase modulation called "PCM/FM" in the IRIG 106 standard to solve the "two-antenna problem". This problem arises when two transmit antennas are used for full spatial coverage at the cost of self-interference caused by the different delays between the transmit antennas and the ground-based antenna. The space-time block encoder is described using bit-level operations on the input data stream. The space-time decoder uses coherent combining and maximum likelihood sequence estimation to produce an estimate of the data sequence. Simulation results for zero and various non-zero differential …

Towards Modern Graph Learning: From Graph Neural Networks To Large Language Models, Jiarui Feng

McKelvey School of Engineering Graduate Student Theses & Dissertations

Graph-structured data provides a fundamental representation for modeling complex systems, from social networks to molecular interactions. Learning effective representations from such data is therefore a central problem in machine learning. While Graph Neural Networks (GNNs) have emerged as the dominant paradigm for this task, achieving strong performance across node, edge, and graph-level predictions, they face significant limitations in expressiveness, adaptability, and generalization. Specifically, standard architectures often struggle to capture complex substructures—such as cycles and motifs—that are critical in scientific domains. Moreover, many models are tailored to specific tasks or distributions, limiting their ability to generalize across heterogeneous graph types. In …

Essays On Empirical Research Of Education, Criminal And Decision, Hsuan-Hua Huang

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation consists of three essays in applied microeconomics, examining how subjective beliefs, institutional designs, and policy incentives shape critical life-cycle decisions in education and public safety. The first chapter investigates how students form beliefs about their academic ability and how the misalignment between perceived and benchmark ability shapes high-stakes educational sorting. Using longitudinal data from Taiwan, I show that these ability gaps systematically predict school and track choices. By developing a model of utility maximization under perceived ability, the results highlight that subjective beliefs, rather than objective scores alone, are central to educational outcomes and potential mismatches in school …

Dietary Manipulations Of The Undernourished Infant Microbiome, Cyrus Zhou

Arts & Sciences Graduate Student Theses and Dissertations

Today, undernutrition affects approximately 150 million children worldwide. During the first two years of life, the healthy gut microbial community undergoes a series of predictable developmental transitions. These transitions are delayed in undernourished children resulting in microbiota “immaturity.” In a foundational study, immature gut microbial communities from undernourished children and normally developing communities from chronologically age-matched healthy children living in the same area were transplanted into groups of germ-free mice consuming the same diet – one representative of what consumed by the study population. Compared mice with a mature gut microbiome, mice with an immature gut microbiome had impaired weight …

Spontaneous Blood Oxygen Level Dependent Signals In Glioblastoma-Bearing And Aging Brains, Ki Yun Park

Arts & Sciences Graduate Student Theses and Dissertations

Brain activity fluctuates across timescales from microseconds to decades, reflecting processes ranging from rapid synaptic transmission to slow neuromodulatory and homeostatic changes. Resting-state functional magnetic resonance imaging (rs-fMRI) captures the slow end of this spectrum (spontaneous blood oxygen level-dependent (BOLD) fluctuations over tens to hundreds of seconds), which reflect the integrated output of these underlying processes and are increasingly recognized as sensitive to both pathological and physiological brain states. The core of this thesis examines rs-fMRI as a biomarker for two clinical entities: glioblastoma and aging. Reliable biomarker development requires both methodological rigor and analytic breadth, knowing what the method …

Living shorelines, or nature-based solutions, have emerged as a preferred approach to coastal restoration, but have not been well studied or monitored postimplementation. This project evaluated the efficacy of living shorelines in protecting and stabilizing coastal morphology in Palm Beach County’s Lake Worth Lagoon. The study assessed surface and subsurface sedimentology, short-term water-level variability, and morphological change at two living shoreline areas of Jewell Steinhardt Cove and Snook Islands Natural Area. Each shoreline area has different breakwater designs aimed at stabilizing the shoreline with recruitment of oysters and mangroves in the Lake Worth Lagoon. Overall, seasonal morphology and sediment data …

Saltfish And Seedcake: Examining Fantasy Through Food Studies, Isabella Martins-Simonsen

Electronic Theses and Dissertations 2020 - Present

Although mundane and often overlooked in reality, in fantasy, food, like all other things, is entirely symbolic. Therefore, considering food closely when analyzing a fantasy text offers unique insights into the world being developed, the characters within that world, and the author’s own understanding of both the real and “secondary” world. In this paper, I consider the foods of Earthsea, Narnia, and Middle Earth to offer various perspectives on the worldbuilding and examine the implications of different foods in these well-known settings. For example, the tea served in Narnia creates a fantasy world that is more normal than the strange …

Patriots And Protestant Dissenters: Early Religious Disestablishment In Revolutionary South Carolina, Nathan James Shull

Electronic Theses and Dissertations 2020 - Present

In 1778, the newly independent government of South Carolina broke with more than a century of precedent and disestablished the Church of England by enacting Article XXXVIII of its State Constitution. This thesis weaves together the interconnected stories of Patriots such as William Tennent, Christopher Gadsden, Charles Cotesworth Pinckney, Oliver Hart, Richard Furman, and William Henry Drayton, demonstrating how they converged on disestablishment. While the historiography has focused on one or another religious or political group, this thesis asserts that an array of South Carolinians from across the political spectrum coalesced around disestablishment as a pragmatic solution to a variety …

Fabrication Of Su-8 Electrically Actuating Membranes, Tyler James Adams

Theses and Dissertations

This work investigates SU-8 polymer waveguides as a fabrication platform for integrated optical structures. Surface roughening using oxygen plasma etching is used to induce controlled optical scattering, enabling direct observation of guided modes and providing insight into waveguide behavior. Building on this, waveguide geometry is modified through an elevated scattering region (ESR) design, which reduces transition losses and improves scattering efficiency by preserving optical volume within the guiding region. In parallel, suspended SU-8 membranes are fabricated and evaluated for mechanical stability, providing a platform for integrating optical structures beyond conventional substrate-bound configurations. These membranes are further characterized under electrostatic actuation, …

Language that includes race-evasive frames is used by White individuals to maintain a status quo wherein White individuals hold greater access to societal power and resources than people of color. Race-evasive frames include abstract liberalism, naturalization, cultural racism, and disconnected power-analysis. In higher education, use of race evasive frames has been primarily documented in White college students and White faculty members. This study addressed in a gap in the literature related to race evasion in White student affairs professionals. Student affairs professionals provide direct support to college students. Scholars have suggested that student affairs professionals carry responsibility for advancing equity …

Resource-Aware Cooperative Perception For Autonomous Driving, Matthew Magee

Theses

In recent years, many new vehicles equipped with autonomous driving capabilities have been deployed around the world, but they still have a number of failure cases. One proposed solution to improve performance in these scenarios is cooperative perception, a paradigm in which vehicles communicate with other vehicles and nearby sensors to collect additional perception information about the environment. Prior work has demonstrated that cooperative perception can be accomplished with the high accuracy and low latency needed for autonomous driving. However, state-of-the-art systems rely on unrealistic assumptions about the conditions of the network connections between participating nodes and the compute resources …
