Utilizing The Spatial Evaluation Of Language And Flexibility For Youth (Self-Y) In Clinical Case Conceptualization, Katelyn Frahm

Graduate Theses/Dissertations

Individuals diagnosed with autism spectrum disorder (ASD) often experience challenges with restricted and repetitive behaviors, relating directly to challenges with psychological flexibility (Hyman et al., 2020; Hayes et al., 2006). Unfortunately, the history of applied behavior analysis has extended harmful implications of treatment that have focused on compliance training and punishment, often worsening psychological flexibility (Sandoval-Norton et al., 2019). Research is calling behavior analysis to combine flexible approaches, such as Acceptance and Commitment Therapy, with technologies exploring the intricacies of individual relational networks (Hayes et al., 1999; Hayes et al., 2022; Hayes & King, 2024). The present study introduced the …

Emerging Technology And U.S. Presidential War Powers, Blaine D. Ravert

Graduate Theses/Dissertations

Autonomous weapons, anti-satellite weapons (ASAT)s, cyber operations, and drones, among other examples of emerging and advanced technologies, have produced changes in how the United States (U.S.) conducts military operations. This thesis argues these technologies are connected by three common features that make U.S. congressional oversight of their usage by U.S. presidents more challenging. First, these systems enable U.S. presidents to act with increased speed, giving the U.S. Congress less time to respond. Second, some legal arguments suggest many uses of these technologies will not implicate war powers related authorities. Third, the legally unsettled nature of these weapons makes it more …

Death Of A Doctrine: The End Of Classical Deterrence In A Complex Multipolar World, Daniel H. Wang

Graduate Theses/Dissertations

Today's deterrence is dramatically different from that during the Cold War. This thesis examines how changes in global geopolitics altered deterrent frameworks and how those changes threaten strategic stability. Traditional nuclear deterrence is built on clear adversaries, established escalation protocols, and predictable outcomes that are increasingly obsolete when facing modern realities. Adversaries employ hybrid strategies below the traditional thresholds of nuclear deterrence while integrating nuclear capabilities into these hybrid tactics, driving a distinct disadvantage for traditional deterrence frameworks. Russia uses nuclear signaling with gray zone operations, China combines multidomain operations with nuclear deterrence to employ a full spectrum of capabilities, …

Applied And Conceptual Implications Of Relational Density Theory In Machine Learning And Behavioral Economics, Bentley J. Elliott

Graduate Theses/Dissertations

Relational Density Theory (Belisle & Dixon, 2020a) is an advanced conceptualization of Stimulus Equivalence (Sidman & Tailby, 1982) and Relational Frame Theory (Hayes et al., 2001) that allows behavior scientists to measure the strength, formation, and malleability of covert behavioral experiences such as attitudes, biases, and probabilities. Relational density combines principles of behavior with the fundamentals of Newtonian classical mechanics to quantify the dimensions of relational framing as a tool for examining behavior. This thesis contains two studies on relational density in context. The first study utilized relational density theory and principles of behavioral economics to measure attitudes and charitable …

Effect Of Reduction Annealing On The Structural And Electrical Properties Of Α-Moo3 Thin Films, Sandipani Ghosh

Graduate Theses/Dissertations

2D layered molybdenum oxide has attracted significant research interest due to its tuneable bandgap and diverse structural, chemical, electrical, and optical properties influenced by growth parameters and synthesis techniques. In this study, the effects of reduction annealing on the structural and electrical properties of few-layer MoO₃ thin films, deposited on Si/SiO₂ substrates via pulsed laser deposition, were investigated. X-ray diffraction revealed nanocrystalline structures with a preferred (020) orientation, reduction annealing produced highly crystalline orthorhombic α-MoO₃ with reduced unit cell volume. FESEM/EDS provided detailed analyses of microstructures and elemental compositions. Raman spectroscopy confirmed the orthorhombic structure, with characteristic peaks at 667, …

Relational Density Theory And Intercultural Interaction: Identifying And Shifting Perceptions Of At-Risk Groups, Ryan T. Moser

Graduate Theses/Dissertations

Intercultural interaction is an important aspect for fostering global engagement and competence, yet we find that despite the numerous opportunities, many don’t engage cross-culturally. The current paper utilizes Relational Density Theory (RDT; Belisle & Dixon, 2020a) to examine and modify perceptions of approachability through two experiments. In experiment 1, a Multidimensional Scaling Procedure (MDS) was utilized to identify at-risk groups for non interaction among college students as well as willingness to engage. In experiment 2, a Stimulus Pairing Observation Procedure (SPOP) was utilized to determine whether exposure to positively valanced stimuli could shift the perceptions of the at-risk groups to …

Activity, Movement, And Reproductive Patterns Of The Northern Giant Musk Turtle (Staurotypus Triporcatus) In Belize, Larissa Sage Saarel

Graduate Theses/Dissertations

The Northern Giant Musk Turtle (Staurotypus triporcatus), a near-threatened species native to southern Mexico, Guatemala, Belize, and western Honduras, faces multiple environmental challenges, yet its activity patterns, movement patterns, and reproductive biology remain poorly understood. This thesis investigates both seasonal activity and reproductive cycles of female S. triporcatus in Belize. To assess diel and seasonal activity, I tracked 12 female turtles and collected data using activity loggers. I also collected movement data through radio-telemetry and acoustic tracking methods. Results indicated that the species is primarily nocturnal, with increased activity during the wet season, particularly during flooding events. Turtles …

The Effects Of Corporal Punishment In Childhood On Early Adulthood Cortisol And Aggression, Tyler Priest

Graduate Theses/Dissertations

The current study aimed to see if experiencing corporal punishment led to more aggressive behaviors as well as higher cortisol levels than in those who did not experience corporal punishment. The study also examined whether self-regulation moderated the relationship between corporal punishment and levels of aggression. Morning cortisol levels were collected from participants, and they completed a demographics survey, an aggression index, a corporal punishment index, and a self-regulatory inventory index. A T-test found that there was not a significant difference in morning cortisol levels between those that experienced corporal punishment and those that had not experienced corporal punishment. A …

Ordinary Signs, Practical Magic, Erin Patricia Tyler

Graduate Theses/Dissertations

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 …

Exploring Power Dynamics In Ghana Through Ceramic Sculpture, Collins Yaw Antwi

Graduate Theses/Dissertations

The works in this thesis explore the implications of power dynamics such as inequality, power struggle, and oppression within Ghana’s society. I abstract specific elements such as coins, and especially cowry shells which honors Ghana’s past through their use as a source of currency in the colonial era and further serves as a metaphor that represents power. Platters and bowls from different cultures serve as a container for these dynamic symbols of power. By incorporating these elements in my sculptures, I bring attention to the struggle and challenges Ghanaians have experienced over the years. In other ways, I find it …

Hair-making, a skill passed down through generations in my family, began as a personal practice and has evolved into a powerful means of exploring and showcasing the cultural significance of hair braiding through creative works. The sculptures included in this thesis, Braiding Culture Through Ceramics & Mixed Media Sculpture, feature hair sculpture, afro combs, stools, adire batik made from materials such as clay, wood, glaze and cotton fabric. These materials are carefully selected for their cultural relevance and …

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 …

Critical Mineral Exploration In The Superior Province Of Northwestern Minnesota - A Geophysical Data Analysis, Michell L. Waterman

Graduate Theses/Dissertations

The Archean basement geology of northwest Minnesota, a region covered by glacial deposits and historically underexplored for minerals, was analyzed using gravity, magnetic, radiometric, and geochemical data. These datasets were integrated to aid in identifying subsurface structures and evaluating the area's potential for economic mineralization within the Wabigoon, Quetico, and Wawa Subprovinces of the Superior Province. Gravity and magnetic datasets, analyzed through upward continuation, derivative maps, and two-dimensional modeling, revealed distinct northeast-to-southwest-trending maxima corresponding to fault-bounded, high-density, and magnetically susceptible bodies. These features were interpreted as mafic to ultramafic intrusions and dikes, several of which align with known Proterozoic fault …

Effects Of Liraglutide On The Gut Bacterial Community, Jami Anne Bull

Graduate Theses/Dissertations

Overweight and obesity are major health concerns associated with metabolic disorders and gut dysbiosis. Treatment options such as GLP-1 receptor agonists, like liraglutide, promote weight loss and improve insulin sensitivity; however, their impact on the gut bacterial community remains unclear. This study investigated the effects of liraglutide on the gut bacterial community of diet-induced obese (DIO) mice using Illumina DNA sequencing of the bacterial 16S rRNA gene. My study used twelve-week-old male C57BL/6J DIO mice. They were placed on a high-fat diet and treated with liraglutide (0.2 mg/kg) via daily subcutaneous injection for 14 Days. High-fat and low-fat diets control …

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). …

The Role Of Host Factor Sptbn1 In Hiv-1 Capsid Uncoating In Human Microglial Cells, Callie Marie Fry

Graduate Theses/Dissertations

HIV-1 is the virus that causes acquired immunodeficiency syndrome (AIDS), and currently, there is no cure once an individual is infected. The development of new drugs targeting HIV-1 replication steps is essential for keeping viral loads low or undetectable to prevent further transmission. An attractive replication step for new drug targets is viral capsid uncoating, where the virus loses the protein structure encapsulating the genome. The exact mechanism of capsid uncoating is unknown; however, several host-factors may be involved including protein SPTBN1. Recent studies have shown a significant decrease in viral infectivity when SPTBN1 is knocked down, yet its role …

Inoculating Soybean Plants At Different Growth Stages: Selecting Bradyrhizobium, Sinorhizobium, Or Both, Matthew R. Knoll

Graduate Theses/Dissertations

Soybean plants rely on nitrogen for growth, however atmospheric nitrogen (N2) is not a usable form and needs to be converted into different forms that are available to the plant. Nitrogen fixing bacteria such as rhizobia form symbiotic relationships with Soybeans in exchange for shelter and excess plant sugars. As a result, the plant can get the nitrogen it needs. There are four main genera of rhizobia that can form root nodules on Soybean including Bradyrhizobium, Sinorhizobium, Mesorhizobium, and Rhizobium. At this point, the effect that age of the host plant has on the selection of …

Learned Helplessness: An Online Replication And Validation, Arshpreet (Sunny) Kandola

Graduate Theses/Dissertations

The current study entails the partial replication of a classic learned helplessness two-phase triadic design experiment within an online learning context and aimed to validate a new attributional style self-report measure designed to identify individual differences in tendencies to develop learned helplessness consistent with the original reformulation of the hypothesis. Further, recent innovations in neuroscientific technology have allowed for a deeper examination of the mechanisms at play, finding support for a major re-interpretation of the theory of learned helplessness - suggesting that helplessness is more so the default passive response, while the active ingredient that is detected or expected (i.e., …

The purpose of this study was to design and implement a unit of instruction based upon three common approaches to teaching rhythm in the beginning band setting and to examine their effect on the rhythmic understanding, confidence, and independence of students in my sixth grade beginning band class. Students received instruction that was traditionally-based, aurally-based, and movement-based for one week each, respectively. An analysis of my teaching was provided by the notes I took that detailed what my students and I did throughout the study. Through my instruction, my students were able to increase their interactions with rhythm. Students were …

Restoration Of Giant River Cane (Arundinaria Gigantea) In Southwest Missouri, Lyndsey D. Rightnowar

Graduate Theses/Dissertations

Giant river cane (Arundinaria gigantea), a native bamboo species, once dominated riparian landscapes across the southeastern United States but has declined to approximately 2% of its historic range. This study evaluated restoration techniques for giant cane in southwest Missouri by examining the influence of rhizome source (putative genotype), planting type, and restoration site on restoration success. I compared two planting types: greenhouse-to-field (G2F) transplanting, where rhizomes were first propagated in the greenhouse before planting, and field-to-field (F2F) transplanting, where rhizomes were directly transplanted from source canebrakes to restoration sites. Rhizomes were collected from four existing canebrakes in Taney …

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 …

Modeling The Impact Of Climate Change On Plant Hardiness Zones Across The Contiguous United States Using Empirical Bayesian Kriging Regression Prediction, Daniel Donkor

Graduate Theses/Dissertations

Mapping plant hardiness zones is crucial to understanding and predicting the spatial distribution of plants in response to climatic conditions. The United States Department of Agriculture (USDA) developed the plant hardiness zones based on the average of annual extreme minimum temperatures using the Parameter elevation Regression on Independent Slope Model (PRISM). While the USDA’s 2012 and 2023 Plant Hardiness Zone maps remain standard references, they offer limited geostatistical transparency that causes more complications in replicating. This study applies Empirical Bayesian Kriging Regression Prediction (EBKRP) method to generate Plant Hardiness Zone maps, analyze spatial and temporal shifts in the plant hardiness …

Cgrp Modulation Of Intracellular Calcium Levels In Trigeminal Ganglion Neurons And Glia, Nicole M. Nalley

Graduate Theses/Dissertations

Elevated levels of calcitonin gene-related peptide (CGRP) are implicated in migraine and TMD pathology, but its effects on the excitability state of Aδ and C-fiber neurons and glia have not been investigated. The goal of this study was to determine changes mediated by CGRP on intracellular calcium levels in trigeminal ganglion neurons and glia in response to depolarizing stimulation. Intracellular calcium levels were determined in Aδ and C-fiber neurons of primary trigeminal ganglion cultures obtained from neonatal Sprague Dawley rats using Fura-2 and fluorescent microscopy. Cells were left untreated or preincubated for 2 hours with CGRP, then incubated with the …

The Influence Of Flower-Microbe Interactions On Bumble Bee Behavior And Gut Microbiome Composition, Success Chiamaka Ekemezie

Graduate Theses/Dissertations

This thesis examines how microbial interactions in floral nectar and environmental variation influence bumble bee (Bombus spp.) foraging behavior and gut microbiome composition. Pollen germination experiments and behavioral assays in the lab tested whether Metschnikowia reukaufii (yeast) and Acinetobacter nectaris (bacteria) induce pollen germination and bursting in nectar and affect bee behavior subsequently. Both microbes reduced intact pollen, but bees did not alter flower preference. Furthermore, the study also assessed how floral and bee community composition shaped gut microbiome composition across six Missouri prairies. Using amplicon-sequenced fungal ITS and bacterial 16S rRNA genes, I found that fungal microbiome composition varied …

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 …

The Mythic Seeds Of Human Rights, Joshua Mackenzie Luna

Graduate Theses/Dissertations

In this thesis, I propose a causal relationship between ancient societies’ mythic corpuses and their law codes. I begin by presenting the histories and historiographies of ancient Israel and Mesopotamia to highlight important themes in their development. Then, I place their creation and flood myths side-by-side for comparison, yielding key differences in the way each group conceptualizes human form, value, and purpose. Once these key differences have been established, I compare each group’s set of slave laws to demonstrate how each law code remains philosophically consistent with its respective set of myths and diametrically opposed to the set from the …

Generational Exposures To Cerium Oxide Nanoparticles And Perfluorooctanesulfonic Acid Affect The Performance Of Daughter Plants, Preston Clubb

Graduate Theses/Dissertations

The effects of parental stress on the performance of next generation exposed to another contaminant were investigated. Wheat was exposed to cerium oxide nanoparticles (CeO2-NPs) in first and second generations and exposed to perfluorooctanesulfonic acid (PFOS) in the third generation. Phenotypic or metabolic responses were assessed at 21-day (short-term exposure) or 90-day (long-term exposure) exposure periods. Biomass production, chlorophyll content, enzyme activity, and membrane damage were measured at short-term exposure, while elemental and PFOS concentrations, and grain metabolites were analyzed in long-term exposure. Results showed that continued exposures to CeO2-NPs and PFOS enhanced chlorophyll content but reduced concentrations of important …

A Novel Deterrence Strategy: Denial Through Space And Cyberspace, Nathan A. Heard

Graduate Theses/Dissertations

The United States faces numerous security threats now and in the coming decades. Authoritarian and revisionist powers such as China and Russia, along with regional proxies, are destabilizing the international order. The ability of the United States to adequately address these present and future threats is constrained by conventional and nuclear forces in need of recapitalization, a rising national deficit, disagreements over the direction of U.S. foreign policy, and a defense industrial enterprise that has its roots in the Cold War. In a multi-peer threat environment, this situation erodes U.S. credibility and is an invitation for aggression. Coercion, coordinated multi-theater …
