Minimally Invasive Total Versus Partial Thymectomy For Early-Stage Thymoma, Irene Helenowski, Alex Pohlman, Zaid Abdelsattar

Biostatistics Collaborative Core: Faculty Publications and Other Works

Background/Objectives: Total thymectomy is currently the gold standard operation for treating thymoma. However, recent studies have suggested the potential health consequences of thymus removal in adults, including possible increased autoimmune disease and all-cause mortality. In this context, we assess oncologic outcomes following total vs. partial thymectomy for early-stage thymoma. Methods: We identified patients diagnosed with WHO types A–B3 thymoma between 2010–2021 from a national hospital-based dataset. We excluded patients with stage II or higher disease, open resections and perioperative chemo-/radiation therapy. We stratified patients into total and partial thymectomy cohorts. We used propensity score matching to minimize confounding, …

Form A More Perfect Union: Educational Direction For Teaching Effective Political Discourse, Brian Merchant

School of Education and Leadership Student Capstone Projects

Efforts to strengthen civics education in support of democracy have expanded in recent years. Schools increasingly offer project-based learning, authentic assessments, and rigorous course options. Yet while standards emphasize argument formation, little attention is given to the practical skills required for political discussion. Research shows that public schools, with their diversity of perspectives, are well suited to foster dialogical approaches to civic discourse. Despite this potential, classroom discussions often lack depth, and educators frequently lack the resources and training to engage students in high-quality political dialogue. This literature review identifies the importance of political discourse education, interdisciplinary practices to improve …

Distinguishing Pex2 And Pex16 Gene Variant Severity For Mild, Severe And Atypical Peroxisome Biogenesis Disorders, Vanessa A Gomez, Oguz Kanca, Sharayu V Jangam, Saurabh Srivastav, Jonathan C Andrews, Michael F Wangler

Duncan NRI Faculty and Staff Publications

Peroxisomal biogenesis disorders (PBD) are autosomal recessive diseases caused by mutations in specific PEX genes that impair peroxisome formation, leading to multi-systemic failure. Symptoms vary, even in patients with variants in the same PEX gene. Our goal is to select PEX mutations and use Drosophila to model a severity spectrum based on genotype-phenotype correlations. Utilizing KozakGAL4 (KZ) cassettes, we replaced the coding sequence of Pex with a GAL4 driver, ideal for making 'humanized' flies in which human PEX can replace the fly loss. We generated Pex2KZ and Pex16KZ lines and assessed them in various behavior assays, confirming their severe phenotypes. …

Effects Of Verbal Tasks On Driving Simulator Performance, Jonathan Cheshire Rann

Theses and Dissertations

We report the results from a driving simulator paradigm we developed to test the effects of simple verbal tasks on simultaneous driving performance. A total of 74 undergraduate students participated in two experiments in which they controlled a car using the steering wheel to track a moving target. The dependent measure, overall deviation from target, was continuously recorded. Experiment 1 (E1) tested tracking performance during slow and fast target speeds under conditions involving either no verbal input or output (Absent), passive listening to spoken prompts via headphones (Listen), or responding to the spoken prompts (Respond). Experiment 2 (E2) was similar …

Stimulation Of The Rostromedial Tegmental Nucleus Induces Long-Lasting Avoidance Behavior, Jacob Ryan Watson

Theses and Dissertations

The role of midbrain dopamine (DA) activity in reward seeking and reinforcement learning is well-documented, contrasting the lesser-understood impact of inhibitory signaling on DAergic activity, especially in the context of aversive learning and avoidance. The rostromedial tegmental nucleus (RMTg) is a GABAergic midbrain structure activated by aversive stimuli and exerts inhibitory influence over ventral tegmental area (VTA) DAergic activity in response to aversive consequences. Stimulation of the RMTg decreases the firing rate of VTA DA neurons and direct inhibition of the RMTg – VTA circuit enhances persistent reward seeking despite aversive consequences, a major criterion of substance use disorder (SUD). …

The Impact Of The Flipped Learning Approach On Student Engagement In A High School Chemistry Classroom, Alana Lyn Hicks

Theses and Dissertations

This mixed-methods action research study investigated the impact of the flipped classroom approach on student engagement and attitudes within a science classroom. Data was collected using student-reported responses on the Classroom Engagement Inventory, Motivated Strategies for Learning Questionnaire, student journal entries, teacher reflective journals, and an observation tracking chart kept by the classroom teacher. Findings revealed that the flipped classroom model significantly increased affective and cognitive engagement among students in a larger class size, as well as for medium-achieving students and girls. These results suggest that while the flipped classroom has the potential to enhance engagement, its effectiveness is influenced …

Clinical Correlates: Using Case-Based Learning In The Physician Assistant Classroom, Pamela Schindler Wilson

Theses and Dissertations

Physician Assistant (PA) education is rigorous and comprehensive. In only 27 months, the students must learn medical knowledge and skills for effective patient care. Instruction must be efficient and effective to teach these students how to be safe and functional PAs. Of primary concern is teaching students how to perform like clinicians, which requires critical thinking, self-directed learning, and teamwork.

This convergent, mixed-methods action research explored the impacts of case-based learning (CBL) in the PA classroom. The findings support using CBL to develop clinical reasoning skills, improve comprehension of the material, and develop self-directed learning skills. CBL requires the students …

Lessons In Game Use: Examining Engagement And Content Knowledge With The Use Of Digital Game-Based Learning Lessons In Biology, Rebecca Anne Valencia

Theses and Dissertations

According to both national and local data, students in high school biology classes are disengaged in content learning and do not demonstrate sufficient understanding of the content taught during units focused on the mechanisms of heredity and gene expression. Traditional teaching methods do not hold their interest which leads to disengagement and missed learning opportunities. The purpose of this action research was to evaluate the effect of digital game-based learning lessons on biology 1 students’ engagement and content knowledge application regarding the mechanisms of heredity and gene expression, as well as on the students’ perceptions of their digital game-based learning …

Regression With Atypical Data: Measurement Error, Periodicity, And Non-Normality, Nicholas W. Woolsey

Theses and Dissertations

Regression is a ubiquitous and fundamental method that can be found in any ele- mentary statistics course. The simplicity and self evidently useful nature of linear regression beguiles a non-negligible portion of researchers into disrespecting assump- tions required by these models, namely in terms of accuracy of covariates and the underlying nature of the data. This disregard can at best lead to meaningless results and at worse cause significant misunderstandings in scientific pursuit.

In this dissertation we strive propose remedies to violations of specific assump- tions. Namely the assumptions that covariates are either observed without measure- ment error or they …

Explainable Process Recommendation Through Multi-Contextual Grounding Of Dynamic Multimodal Process Knowledge Graphs, Revathy Venkataramanan

Theses and Dissertations

Can I eat this food or not? Is this food suitable for diabetes and why? Which AI pipeline is best suited for a given task and dataset? How should an end-to-end pipeline be constructed? These questions differ from factual question-answering tasks. Recipes and AI pipelines are processes consisting of several entities interacting with each other. A recipe consists of ingredients, cooking methods, and their interactions, while an AI pipeline includes datasets, preprocessing techniques, models, hyperparameters, tasks, and results. Each entity must be analyzed individually, and collective inferencing is performed to derive the final decision. This decision-making process, known as compositional …

William Hogarth's Portraiture: A Vehicle For Social Commentary, Kaitlyn Elizabeth Hoff

Theses and Dissertations

William Hogarth is often celebrated for the critiques of eighteenth-century England seen throughout his widely reproduced satirical print series and paintings, however his contributions to portraiture offer a compelling extension of his artistic vision and techniques. This research aims to explore Hogarth’s use of portraiture as a vehicle for social commentary and moral messaging, revealing broader themes of morality, nationalism, and identity among all of his works, comparing this approach to that of both his contemporaries and his own prints.

In examining Hogarth’s portraits alongside other formal portraiture, the socio-political landscape of the time, and existing scholarship, methods such as …

Margery's Visions: Sight, Emulation, And Medieval Wall Paintings In The Book Of Margery Kempe, Kristin L. Harrell

Theses and Dissertations

This project puts the history, context, and reception of medieval murals in dialog with The Book of Margery Kempe to identify neglected parallels between Margery’s sense of sight and the visual culture around her. Guided by a method of recovery that draws on interdisciplinary approaches to text and image, this dissertation combines digital tools, close reading, and archival accounts to compare how Margery responded to visions of holiness—both in spiritual revelations and in physical imagery—in murals which would have been on display during and in proximity to her travels. While mapping, close reading, and analysis have been applied to Margery …

Conjuring Realities: Southern Supernaturalism And Race From The Antebellum Era To The Early Twentieth Century, Dylan T. Kobus

Theses and Dissertations

Conjure practices in the nineteenth-century American South, such as “Hoodoo” or “Voodoo,” are commonly portrayed as primarily “black” beliefs or entrenched in “Africanistic” cultures. For the enslaved, their black spiritual systems, including conjure, were a powerful tool of resistance against the white enslaver. Black conjure practitioners established themselves as an affordable and pervasive medical alternative to often ineffective or harmful professional medicines for black and white Southerners, regardless of class. In this way, conjure challenged the authority of racial capitalism and destabilized the perceived moral and intellectual superiority of whiteness. Moreover, by examining legal documents, newspapers, fictional literature, and oral …

“Cruelty, Bloodshed, And Degradation From The Inauspicious Conjunction Of Stars”: “Magic” In The 1857-58 Rebellion In India, Summer Bordon

Theses and Dissertations

During the 1857-58 rebellion in India, British soldiers and civilians saw ample evidence of Indian belief in “magic”. Prophecies about the end of British rule were implicated in inciting rebellion. When a solar eclipse occurred during the British army’s campaign to regain control of Delhi, victory was attributed partially to Indian superstition. Much of the historiography of the 1857-58 rebellion has uncritically accepted British sources’ conceptions of Indian “magic”, dismissing it as superstitious, politically hindering, and divorced from material reality. Yet, British understandings of magic cannot be taken at face value. Instead, they must be located within broader colonial narratives …

Conceptions Of Epic Heroism In Thomas May’S Continutation, Michael Blake Hoehn

Theses and Dissertations

Thomas May’s A Continuation of the Subiect of Lucan's Historicall Poem till the Death of Iulius Cæser, continues Lucan’s creative vision of critiquing heroism. Despite his attempt at maintaining an indifferent world, May’s Continuation implicitly favors the heroism of the Pompeians.

Both Caesar and the Pompeians base their heroic conceptions on ideals found in Greek and Roman marital and national heroism. Caesar and his enemies believe that his victories in battle result from Fortune’s protection and approval, allowing Caesar to justify the ideals of traditional heroism. However, Fortune in the Continuation acts as an independent force, making these misinterpretations …

The Tur Nout Effect: Challenging The Median Voter Theorem, George Thomas Rogers

Theses and Dissertations

The classical Median Voter Theorem (MVT) predicts that, in a two-party system with majority rule, candidates will converge toward the ideological center to capture the median voter. This logic, grounded in spatial models of political competition, assumes full voter participation and fails to account for the growing ideological polarization in modern democracies. This thesis reevaluates the MVT by incorporating probabilistic turnout into a utility-based model of voter behavior. It theorizes that turnout is shaped not only by ideological proximity but also by expressive motivations, including both strong affinity and strong aversion to candidates. A novel measure of turnout utility is …

Between Florida And The World: Young People And The Politics Of Citizenship, Jessica Flach

Theses and Dissertations

This thesis critically examines how American high school students experience and make sense of global citizenship within the context of a commercial educational tour. Drawing on a case study of students from a Title I public high school in Florida, the research interrogates the narratives of civic transformation promoted by educational travel companies and explores how these narratives intersect with students’ lived realities. Combining ethnographic methods, interviews, and critical discourse analysis, the study reveals that global citizenship is not meaningfully realized through such travel experiences; rather, it is fragmented, depoliticized, and often disconnected from the civic education students receive in …

Characterizing The Relationships Between Cranial Geometry, Brain Morphometry, And Brain Mechanical Properties Using Mr Imaging And Elastography, Jessica Restivo

Theses and Dissertations

Traumatic brain injury (TBI) is a global health concern, with over 69 million cases annually. TBI risk depends on subject-specific neuroanatomical variation, yet research often only considers generic finite element (FE) models, based on the geometry and material composition of a 50th percentile male head. Although highly accurate, subject-specific models require expensive magnetic resonance (MR) imaging, elastography, and time-consuming computational resources. There is a need to create subject-specific TBI models that account for subject-specific variations, without neuroimaging. This study aims to create mathematical models to predict brain morphometry (dimensions, volume) [Objective 1] and mechanical properties (shear stiffness, damping ratio, octahedral …
