From The Battlefield To The Asylum: The Social Construction Of Disability In Italy, 1900 - 1950, Brandie Crisp Robb

Graduate Theses/Dissertations

The Italian social construction of disability reflects a complex interplay between social, religious, political, and religious influences present during the first half of the twentieth century. While Western European and American disability discourse remained similar, those influences unique to Italy resulted in the formation of two distinct disability discourses during the early twentieth century: that of the heroic physically disabled veteran who sacrificed everything for the good of Italy, and the eugenically unfit Italian associated with dependency and uselessness. By combining a theoretical framework that includes critical disability theory with historical methodology, the following thesis demonstrates how the emerging disability …

What I Was And Who I Am, And Before And After, Molly K. Del Rossi

Graduate Theses/Dissertations

This thesis begins with a critical introduction which analyzes varying forms—such as the inverted sonnet—the schools of confessional and post-confessional poetry—and how they differ—and inspiration used for my creative work in poetry. I claim to be a poet who writes primarily based on personal memories. I chronicle my initial encounters with poetry as a teenager through the lens of confessionalism, as demonstrated by Eavan Boland and Anne Sexton. To exhibit my gained knowledge, I reference poetic theorists such as Richard Hugo, Charles Olson, Adrienne Rich, Mary Ruefle, and Gertrude Stein when analyzing which theories and dialogues influence my poetic style. …

The Effect Of Polyethylene Glycol Surface Density Of Dense Brush Gold Nanoparticles On Insulin Fibrillation, Ethan Patrick Grier

Graduate Theses/Dissertations

The development of various neurodegenerative diseases such as Parkinson’s disease and Alzheimer’s disease has been linked to the fibrillation of various proteins within the brain. Parkinson’s disease is specifically linked to the fibrillation of α-Synuclein. During the fibrillation process, the proteins take the form of oligomers, and exposure to these oligomers has been linked to various cytotoxic and neurotoxic effects. Once the fibrillation process is complete, the fibrils made have been shown to be much less toxic than the oligomer stage. This fibrillation process is thermodynamically favorable and is largely irreversible, so one course of action for treatment of these …

Bridging The Gap: Fostering Emotional Expression Through Teaching Strategies In The Middle School Choral Classroom, Jacob Brown

Graduate Theses/Dissertations

This study investigates the impact of teacher-elicited expression strategies (i.e. emotionally evocative metaphor, technical elements through modeling, body of the conductor, understanding the emotional content) on the emotional expressivity of my middle school choral students. Using a mixed-method approach, data was collected through surveys of students' self-evaluations of the expression strategies, and their overall value of expression before and after learning processes that emphasized emotional expressivity. I found that each teacher-elicited expression strategies impacted student expressivity positively. Concrete strategies (i.e., body of the conductor and technical elements through modeling) were highly effective, particularly in my beginner and intermediate choirs, while …

Territorial Behavior Of A Terrestrial Salamander: Effect Of Physical Stress, Residency Status, And Sex, Abigail C. Nagl

Graduate Theses/Dissertations

Environmentally induced stressors can include threats from predators and competitors. Individuals in territorial species, including the subject of this study, Southern Red-backed Salamanders, Plethodon serratus, face ongoing competitive threats, and loss of contests may be more consequential to territory owners (losing a territory) than to intruders (continuing to be without a territory). Therefore, when the threat of increased predation risk is added, residents may respond differently than intruders. Here, I tested the impact of physical stress, residency status and sex on the territorial behavior of Southern Red-backed salamanders. Territorial behavior was assessed through staged contests with same-sized and same-sexed individuals, …

Threshold: Stories & Graphic Memoir, Emily Kay Lewandowski

Graduate Theses/Dissertations

Threshold: Stories & Graphic Memoir, a collection of fiction and graphic memoir, explores the in-between stages of loss and grief. Both the fiction and graphic memoir pieces utilize the technique of the “narrative echo,” coined by John Gardner, to stylistically explore and interrogate these stages of in-betweenness. The final piece in this collection, “I Hope You Find Me On Mars,” is a queer expansion of Octavia Butler’s trilogy Lilith’s Brood. Each piece uses unique voice and styling to contribute to the larger literary community by interrogating manifestations of identity, queerness, and grief.

Development Of Cyan And Blue Thermostable Fluorescent Proteins: Characterization And Structural Analysis, Acacia J. Jurkowski

Graduate Theses/Dissertations

Fluorescent proteins are commonly used as cell markers in living organisms. Modifications by mutation can be used to improve the qualities of these proteins including fluorescence, thermostability, pH stability, and chemical stability. The goal of this project is to use mutagenesis to improve the fluorescence of thermostable cyan and blue proteins derived from the thermal green protein (TGP). The first cyan protein developed by the DeVore lab (CTP 0.0) shifted the fluorescence to cyan but decreased the quantum yield (Φ_F) to 0.056. Further mutations were incorporated to increase the quantum yield through incorporating hydrogen bonding interactions to the …

A Study Of Collegiate Equine Team Funding, Expenditures, And Recruitment Strategies, Sydni Marie Nilles

Graduate Theses/Dissertations

Collegiate equine teams (including horse judging, equestrian, ranch horse teams) have been recognized for their contributions to students' personal and professional development for post- graduation success. Teams have been used to provide opportunities, a sense of belonging and allow for experiences students may not have elsewhere. However, there is a notable gap in knowledge as to where funding comes from and how much teams may be able to budget for expenditures. Recruitment tactical knowledge provides other teams with knowledge of potential areas they may be lacking or unaware of. I used an online survey to understand current ranges of support …

Cyber Warfare And The Future Of Conflict, Victor A. Mercado

Graduate Theses/Dissertations

This thesis examines whether cyber warfare now poses a more immediate threat to U.S. national security than weapons of mass destruction (WMD). Cyber operations have become a dominant instrument of contemporary conflict, with malicious actors operating in a persistent “grey zone” that blurs traditional boundaries between war and peace. These operations target military and civilian entities, both directly and often as collateral damage due to the uncontrollable nature of cyber threats. WMDs, despite their catastrophic destructive potential, remain largely constrained by established deterrence frameworks.

The evolving nature of cyber warfare warrants comparison to WMD effects and impact, as cyber capabilities …

Ordinary Signs, Practical Magic, Erin Patricia Tyler

Ordinary Signs, Practical Magic outlines my personal wrestling with belief – in art, in spiritual intervention, in self, and in the quiet forces that guide us through the world. Using the frameworks of ordinary signs – tactile and visual cues that ground and orient me and practical magic – what I define as human intervention and the act of creation – this work examines how attention, care, and materiality shape my understanding of meaning and connection. Through visual data collection –photography, assemblage, collage, drawing, painting and found objects – alongside poetic writing and personal narrative, my thesis navigates the tension …

Responses Of Native And Invasive Aquatic Vegetation To Changes In Water Depth In An Ozark Spring-Fed Pond, Daphne Miles

Graduate Theses/Dissertations

Spring-fed aquatic ecosystems in the Ozark Highlands are characterized by stable water depths, clear water, and diverse aquatic vegetation (filamentous algae, submerged, floating, and emergent plants). Sudden changes in water depth can impact aquatic vegetation dynamics but the impacts of prolonged changes are poorly understood. I investigated seasonal and annual changes to aquatic vegetation abundance in a spring impoundment during and after a two-year period of low water depth that was caused by a broken outlet below an artificial dam. Water depth was significantly lower in 2020 and 2021 (low water years), compared to 2022 and 2023 (high water years). …

Dystopian Politics In The Hunger Games Series, Tristan Hogan

Graduate Theses/Dissertations

Suzanne Collins’s The Hunger Games series takes readers to a fictional country known as Panem that hosts an annual nationwide celebration in which adolescents compete in a battle to the death. In this analysis, I approach this book series with a Marxist lens to argue that the capitalistic system in Panem satirizes American culture in the early 21st century. Every novel in the series, through this theory, can be read as what scholars identify as a “critical dystopia,” a defamiliarized version of our culture, upheld through institutions and social participation in a way that satirizes ours. I argue that the …

Victim-Offender Relationships And Their Influence On Crime Brutality And Sentencing Outcomes In Capital Homicide Cases, Samantha Jane Trowbridge

Graduate Theses/Dissertations

This study examines capital murder cases in Missouri from 1976 to 2022 to explore how victim-offender relationships relate to both the brutality of homicides and sentencing outcomes. It addresses three main questions: What are the different types of victim-offender relationships in these cases, and how frequently does each type occur? How do these relationships influence sentencing outcomes, particularly the likelihood of receiving the death penalty versus life without parole? And which types of relationships are associated with the highest and lowest levels of brutality? The study uses official court records and applies a coding process to analyze relationship type, sentencing …

Constructing Hamiltonians Using A Wannier Basis Set To Study Localized Electronic Interactions Using A Variational Quantum Eigensolver, Matthew D. Bruenning

Graduate Theses/Dissertations

In this study, I demonstrate how Wannier basis sets can be used to construct a tight binding Hamiltonian that is localized in real space. This Hamiltonian can then be studied using the Variational Quantum Eigensolver (VQE), which is able to extract the minimized energy of the system. Unlike Bloch functions, Wannier functions are localized in real space, allowing each Hamiltonian element to represent orbital overlaps between neighboring atomic orbitals. This locality enables a substantial reduction in the Hamiltonian’s size by including only the orbital projections that contribute meaningfully to localized interaction energies, such as those involved in adsorption. As a …
