(Human)Ities In The Field Of Business, Emma M. Bitting

Honors Theses

Business is often seen as a field driven by numbers, but it is fundamentally powered by shared narratives, such as branding and mission statements. Increased optimization and efficiency has resulted in industries stripped of their humanity, leaving professionals interpersonally deficient. In an increasingly competitive workforce, one’s humanity has become a primary differentiator from the competition (artificial or otherwise). The division between the humanities and business has become a professional liability apparent to any observer, yet it is rarely addressed as the systemic failure it has become. This very divide increasingly hinders progress, rather than serving as the specialization of fields …

Beat Behind The Bark: Investigating The Effects Of Music Tempo On Canine Physiological And Psychological States, Marley Lanier

Honors Theses

This study explores how the tempo of music, measured in beats per minute (BPM), affects dogs' heart rate and oxytocin levels, adding to past research that shows that music affects physiological and behavioral states in dogs. Being able to understand these effects holds practical implications for improving overall well-being in canines in environments such as homes, shelters, and clinical environments. Using a within-subjects design, the dogs were exposed to slow and fast versions of one instrumental track, along with a white noise baseline condition before each randomized condition. Heart rate was recorded continuously throughout the session, and oxytocin saliva samples …

Bottles, Butterflies, And Biomass: Recycled Glass Sand, Microbial Additions, And Herbivory Effects On Milkweed Growth, Kealey Skinner

Honors Theses

Plant-soil-microbe interactions are integral components of ecological networks and drive ecosystem function from the bottom-up. Whereas herbivores regulate ecosystem function from the top-down, having opposing and potentially complementary effects on ecosystem function. My thesis sought to understand how below-ground microbial communities contribute to herbivore preference and plant biomass across varied soil substrates. My thesis asked: how do substrate and soil microbial communities influence herbivore preference and plant biomass accumulation on swamp milkweed (Asclepias incarnata)? To address this question, seedlings of A. incarnata were sown in 2.5 cm wide × 10 cm deep pots filled with either natural beach sand or …

Comparative Investigation Of Bacterial Adhesion On Medical Device Thermoplastics, Dev V. Mehta

Honors Theses

This project will focus on determining if differences in bacterial cell wall composition influences adhesiveness to thermoplastic materials used to construct patient orthotic splints. Bacteria with decreased adhesion are unable to remain bonded to orthotic splints, increasing its ability to transfer to a patient’s wound, leading to an infection. Antibiotic resistant bacteria used in this investigation included gram-positive cocci vancomycin-resistant (VRE) Enterococcus faecalis, methicillin-resistant Staphylococcus aureus (MRSA), and gram-negative rods extended-spectrum beta-lactamase (ESBL) Escherichia coli and Pseudomonas aeruginosa. Each test bacterium is a major pathogen causing healthcare-associated infections (HAIs). Saline, artificial perspiration, and ascites fluids were used to determine the …

Evaluating Fungal Endophytes Inoculation As A Mechanism For Salt Tolerance In Juncus Roemarianus, Rani Badve

Honors Theses

Salinity stress is increasing in coastal and estuarine ecosystems due to increasing temperatures and the reduction of freshwater inputs via precipitation pattern changes. Elevated salinity can negatively affect plant survival, threatening the stability of coastal wetlands and the ecosystem services they provide. Juncus roemerianus is a common and dominant marsh plant in the Northern Gulf Coast that lives in varying salinities. Growing evidence suggests that root-associated fungal endophytes may contribute to enhanced stress tolerance; however, the response of fungal communities to salinity remains poorly understood.

This study evaluated how salinity influences the abundance and diversity of culturable root-associated fungal communities …

Evaluation Of The Effectiveness Of Antihypertensive Therapy Chosen Through Maternal Hemodynamic Profile Analysis, Margaret Weimer

Honors Theses

Medication choice is tightly regulated in most situations, but in the field of obstetric medicine, the American College of Obstetricians and Gynecologists (ACOG) recommends both labetalol and nifedipine as oral treatments for emergent hypertension, with no preference shown between the two. Studies have suggested that consideration of hemodynamic profile may be an effective way to determine medication, but have not considered the Rule of 55, a simple calculation to predict hemodynamic profile. The goals of this study were to determine whether tailoring the oral hypertensive medication to a patient’s hemodynamic profile is associated with better blood pressure control within 72 …

The Personality Of Place: Physical Geography And The Shaping Of The Nineteenth-Century German Immigrant Ethnic Identity, Abigail Ward

Honors Theses

In the nineteenth century alone, approximately five million German-speaking immigrants arrived in America. However, the motivations of these individuals for moving to America, far from identical, were nearly as numerous as the individuals themselves. The German ethnic identity in America was not uniform, but the expression of many factors having to do with both the Vaterland and the new land. These factors ranged from the timing of emigration, which was largely influence by religious, political, and economic upheaval in Europe, to each German’s system of values, which dictated the kind of future he saw for himself and therefore where he …

Acute Effects Of The Psychoactive Pollutant Fluoxetine On The Antipredator Behavior Of The Gulf Killifish (Fundulus Grandis), Semyra Reus

Honors Theses

Pharmaceutical contaminants are increasingly prevalent in aquatic environments, yet their sublethal effects on ecologically relevant behaviors remain poorly understood, particularly in estuarine systems. Selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine, are of particular concern due to the conserved role of serotonin in regulating behavior across vertebrates. Here, we investigated how acute exposure to environmentally relevant concentrations of fluoxetine influences anti-predator behavior in Gulf killifish (Fundulus grandis), a key estuarine fish commonly found in saltmarsh habitats. Killifish were exposed to control (0 ng/L), low (17.8 ng/L), and high (596 ng/L) fluoxetine concentrations and subsequently tested in the presence …

Choosing Death: The Moral Legitimacy Of Voluntary Active Euthanasia, Emma Rougeou

Honors Theses

During the last three decades, the issue of physician assisted suicide has captivated the interest of private citizens and state legislatures. Thinking about the matter of end-of-life concerns, particularly surrounding euthanasian (practices that hasten the deaths of suffering terminally ill people) have shifted. Views of private citizens and state-level legislation reflects a “slow shift to more permissive attitudes” (Cohen et al., 2012). Meanwhile, as recently as March 2026, state legislators in conjunction with the NY State Governor, passed a bill legalizing medical aid in dying for terminally ill patients. This thesis is intended to thoughtfully contribute to meaningful discourse on …

Navigating The Nicu Without Words: A Case Study Of A Spanish-Speaking Mother’S Healthcare Experience, Emma Norris

Honors Theses

Background: Few studies examine language barriers in the neonatal intensive care unit (NICU). Miscommunication and lack of understanding between the healthcare team and a NICU infant’s parents may easily occur when the relationship is inhibited by a language barrier. Previous studies show that a lack of parent-provider communication creates additional anxiety for parents. The purpose of this study is to explore and describe the experiences and barriers in communication between an English-speaking nurse, an English-Spanish bilingual nurse, and a Spanish-speaking mother of a NICU infant.

Methods: This project was a case study using an exploratory mixed methods qualitative design. Qualitative …

Urea-Based Boronium Salts As Antimicrobial Agents, Gabriel Allen Merchant

Honors Theses

Quaternary ammonium compounds (QACs) are widely used in disinfectants due to their ability to inhibit the growth of and eliminate microbes. The potency, broad-spectrum activity, and low cost of QACs have made them a cornerstone of modem hygiene. In recent years, QACs have garnered many health and safety concerns due to their overuse and subsequent accumulation in the environment. The increased use of QACs has further led to an increase in antimicrobial-resistant bacteria, making the synthesis of novel antibacterial compounds vital to combat this growing threat. Recent advances in boronium salts offer a unique alternative to address these adverse effects. …

Community Perceptions Of A Hospital-Based Doula Program In Mobile, Alabama, Sarah Laney

Honors Theses

Background: The maternal mortality ratio in the United States is much higher than the mortality rate for women who live in other countries with similar Human Development Index scores. Black women are more likely to die than their white counterparts. Most of these deaths are preventable. Patients feel like they are being ignored, or that they are not being seen. Doula care is a possible solution to these problems.

Purpose: The purpose of this study was to assess patient understanding and perception of doulas as well as comparing desire for doulas to demographics and past experiences to search for relationships. …

Spectral Characterization Of Colorectal Cancer Using Excitation-Scanning Hyperspectral Imaging, Natalie Hadad

Honors Theses

Colorectal cancer is one of the most common and deadly cancers worldwide, with a lifetime risk of approximately one in twenty-three for men and one in twenty-five for women. Although early detection significantly improves survival, current diagnostic approaches such as tissue biopsy are invasive, reliant on subjective interpretation, have extended turnaround times, and risk missing flat or depressed lesions that are more difficult to detect than raised polyps. These limitations highlight the need for objective, minimally invasive technologies capable of detecting early tissue changes. This study investigates excitation-scanning hyperspectral imaging (Ex-HSI) as a label-free optical approach for identifying colorectal cancer–associated …

Novel Biomarker Discovery In Multiple Sclerosis, Manisha Gangasani

Honors Theses

Multiple Sclerosis (MS) is a chronic neuroinflammatory disorder affecting the brain, spinal cord, and optic nerve. Patients experience cognitive, motor, autonomic, and emotional symptoms that often overlap with other neurological conditions, making early diagnosis challenging. Current diagnostic criteria require evidence of lesions with dissemination in time and space. Racial disparities in MS outcomes are well documented, with Black individuals often exhibiting greater disease severity, higher relapse rates, and increased disability compared to White individuals. These differences likely reflect a combination of genetic, biological, environmental, and healthcare access factors, underscoring the need to improve early diagnosis and reduce inequities in care. …

Characterization Of Circulating Extracellular Proteome In Plasma Samples Of Triple-Negative Breast Cancer Patients, Brionna Wilson

Honors Theses

Extracellular vesicles (EVs) are membrane-bound vesicles secreted by cells in the body that play an important role in intercellular signaling, immune modulation, and transfer of biomolecules between cells. EV s reflect the physiological state of their cells of origin, so they are being explored as potential noninvasive biomarkers for cancer detection and monitoring. Triple-negative breast cancer (TNBC), an aggressive subtype lacking targeted therapies, is difficult to detect early and currently has no reliable prognostic biomarkers. This study aimed to quantify EV concentrations in the blood serum of TNBC patients (n=40) compared with cancer-free healthy controls (n=35) as well as determine …

Developing A Protocol For Non-Cellular Transplantation Of Donor Mitochondria Into Recipient Cells, Andrew Parton

Honors Theses

Tumor innervation has emerged as a critical feature of cancer progression, with increased nerve density correlating with enhanced aggressiveness, metastatic dissemination, and poor clinical outcome. However, the functional contribution of neurons to tumor biology remains incompletely defined. We recently identified the intercellular transfer of mitochondria from neurons to cancer cells as a mechanism that promotes tumor progression. We therefore hypothesized that disruption of this transfer could attenuate tumor aggressivity. To directly investigate this process, we developed an approach to isolate mitochondria from donor cells and transplant them into recipient cancer cells independently of canonical cell-cell interactions. Transferred mitochondria were tracked …

That Song Sounds Familiar: An Analysis Of U.S. Copyright Considerations In Popular Music, Jessica Johnson

Honors Theses

Much of popular music has started to bear resemblance to songs of the past as artists rely on techniques, including sampling and interpolations, to ensure their song is a guaranteed hit. But what are the legal implications behind that, and is the line between inspiration and copying getting blurred? This thesis aims to consider the precedent of copyright law as applied to modern musical works and how the landscape of popular music has evolved over time to raise more copyright concerns. It also looks at two modern case studies of musical inspiration that have resulted in legal claims: the song …

The Oncoming Light: An Experiential Approach To Psychological Exposition Through Dialogue-Driven Narrative, Benjamin G. Dewitt

Honors Theses

Narrative is a lens through which we understand ourselves, our histories, our futures, and our ties to those around us. Narrative form has undergone vast transformations over time, and in the case of “postmodern” literature, pushes the boundaries of form into the experimental, questioning the truth of knowledge itself. While these experimental works can give rise to uniquely powerful emotional experiences, some components of narrative, when abandoned, may only hinder the immersion of the reader. This thesis evaluates several experimental, dialogue-driven narrative works against these components: linguistic, literal, emotional, and intellectual significance, in a hierarchy of importance as proposed by …

Synthesis Of Novel 1,2,3-Triarylnaphthalenes Via Intermolecular Dehydro-Diels-Alder Reaction, Ethan C. Dailey

Honors Theses

The photo-dehydro-Diels–Alder (PDDA) reaction is a useful method for the construction of substituted naphthalene derivatives from acyclic precursors. While intramolecular variants of this transformation are well established, intermolecular PDDA reactions remain rare due to challenges associated with controlling reactivity under photochemical conditions. Previous studies suggest that electron-withdrawing substituents can promote intermolecular cycloaddition by increasing alkyne polarization and stabilizing reactive intermediates. In this work, the effect of enhanced electron-withdrawing character on intermolecular PDDA reactivity was investigated through the incorporation of a 2,3,5,6-tetrafluoropyridinyl substituent. Corresponding alkyne substrates were synthesized and subjected to photochemical conditions, resulting in the formation of 1,2,3-triarylnaphthalene products. The …
