Religiosity And Spirituality: The Mental Costs And Benefits Of Belief In A College Setting, Tyler Geis

Masters Theses

The relationship between religiosity and spirituality (R/S) with mental health has been widely discussed in more recent years. This thesis examines factors related to religiosity, spirituality, depression, anxiety, and stress, as well as how various stigmas toward mental health, mental health treatment, and mental health treatment seeking may relate to R/S and mental health. Previous literature has identified religious coping with hardship, positive and negative dimensions of sin and behavior, the structure of different religious groups, and overall spiritual wellbeing as factors related to R/S, mental health, and beliefs about mental health . However, most previous literature come to differing …

The Effects Of Auditory Stimulation On Vocal Stereotypy In An Individual With Autism In A Classroom Setting, Natalie Pastor

Masters Theses

Vocal stereotypy, which includes non-functional vocal behaviors such as babbling, grunting, or repetitive phrases, is often seen in individuals with autism spectrum disorder (ASD). Although this behavior is not harmful, it can interfere with learning and social interaction, especially during leisure time. When engaging in vocal stereotypy is disruptive to those around them, it may limit opportunities for meaningful social engagement with peers. The current study builds on prior research by examining the effects of different types of noncontingent auditory stimuli on vocal stereotypy in a classroom setting. This study seeks to answer the question: What is the impact of …

Robust Broadband Characterization Of Flexible Absorbers, Sheet Material, And Liquids Using A Coaxial Structure, Joseph Christopher Stecher

Masters Theses

Modern high-frequency measurement systems require reliable calibration and sample positioning to ensure measurement fidelity. This thesis presents three studies addressing practical limitations in broadband material parameter extraction and instrumentation.

The first study introduces a modified Nicolson–Ross–Weir (NRW) technique for flexible, compression-sensitive materials from 100 MHz to 18 GHz. Rigid 3D-printed spacers ensure precise sample positioning, and a T-matrix–based de-embedding procedure removes spacer effects. Validation using microstrip measurements and full-wave simulation confirms accurate permittivity extraction across compression levels.

The second study extends NRW to sheet materials enabling accurate material characterization. Independent validation using toroidal inductors with leakage correction and parallel-plate capacitors …

Developing Discharge Estimation Algorithm Using Low-Cost Velocity Sensor And Machine Learning, Barkha Gautam

Masters Theses

Accurate river discharge estimation is essential for flood forecasting, water resources management, and hydraulic decision-making; however, continuous discharge records are unavailable at many river locations. Traditional stage-discharge rating curves are widely used but their reliability may decrease when channel conditions change or flow conditions vary rapidly. This study develops and evaluates Long Short-Term Memory (LSTM) models for discharge prediction using 15-minute time-series data from river monitoring stations in Missouri. Two model configurations, a baseline stage-only model and an enhanced stage-plus-velocity model, are developed and evaluated independently at two river sites to determine whether the inclusion of surface velocity improves discharge …

Wattage- And Composition-Dependent Ocular Surface Toxicity: An In Vitro Study On E-Cigarette Aerosol Exposure In Human Corneal Epithelial Cells, Tzu-Ling Lin

Masters Theses

As electronic cigarette consumption continues to escalate globally, its impact on non-respiratory mucosal surfaces, particularly the ocular surface, remains largely understudied. This study investigated the toxicological effects of e-cigarette aerosols using a human corneal epithelial cell (HCE-2) model. Our findings reveal that aerosol exposure induces a significant, dose-dependent reduction in cell viability, exacerbated by higher device wattage and specific flavor agents such as watermelon. Exposure was found to trigger intracellular oxidative stress and the activation of apoptotic pathways, leading to programmed cell death. Furthermore, the upregulation of proinflammatory cytokines suggests that vaping may predispose users to chronic inflammatory conditions of …

Empirical-Based Model Of Spatio-Temporal Errors, Godwin Naaba Ndaa

Masters Theses

This research develops an empirical model to characterize spatial-temporal InSAR errors and improve the accuracy of deformation time-series analysis. Using standardized Sentinel-1 HyP3 products and MintPy, the study quantifies how correlated noise affects velocity precision and validates the results against continuous GNSS velocities.

Residual velocities are near-Gaussian, with σ ~0.92–2.04 cm/yr and ~1 cm/yr on average. Variograms show power-law spatial structure with a non-zero nugget implicating troposphere and decorrelation while errors drop exponentially with more acquisitions; spatial uncertainty is strongly affected by unwrapping errors, coherence, and tropospheric noise, not simply troposphere.

This research applies a discrete choice experiment to examine individual preferences for proposed battery-critical minerals mining projects in Missouri, Minnesota, and Idaho. 1908 respondents evaluated hypothetical mining projects defined by jobs, state tax revenue, the proportion of tailings reprocessed, groundwater impacts, and surface water impacts, under gold and silver versus battery-critical mineral framings.

Conditional and mixed logit models were used to assess the importance of attributes, demographic …

Autonomous Navigation Development And On-Ground Validation For Satellite Rendezvous And Proximity Operations, Logan Banker

Masters Theses

Spacecraft rendezvous and docking are critical mission phases for various applications of spaceflight, including active debris removal (ADR) and in-orbit servicing, assembly, and manufacturing (ISAM). While previous missions utilized humans to perform rendezvous and docking, this style of mission greatly increases safety risks and cannot be implemented on a large scale. Autonomous servicing satellites provide a path towards scalable rendezvous and proximity operations (RPO) because these autonomous agents do not require human intervention. This work presents a lightweight convolutional neural network (CNN) for the navigation system of an agent which analyzes monocular images and predicts the target's position and orientation …

Validating A Low-Cost Radio Frequency Characterization Framework For Development-Grade Software-Defined Radios In Short-Duration Cubesat Missions, Thomas Wayne Francois

Masters Theses

Software-defined radios (SDRs) and CubeSat platforms have reduced the cost and complexity of space-based communication systems, enabling broader participation in satellite missions. While low-cost radio hardware is increasingly accessible, the ability to characterize and validate its performance remains constrained by the high cost and limited access to traditional RF test equipment. This disparity creates a challenge for small satellite development teams, which must characterize communication-system technical performance with limited access to laboratory-grade instrumentation.

This thesis presents a low-cost RF characterization framework for assessing key radio-frequency performance metrics using readily available hardware and measurement techniques. The approach integrates frequency translation, SDR-based …

Examination Of Laser Microwelding As A Technique For The Repair Of Steel Castings, Allan John Woldow

Masters Theses

"Metal castings have long been plagued with minor defects caused by various process and design conditions. Commonly, minor defects are not seen until after machining operations have been completed, and by the time they are identified, they cannot be salvaged in a manner that is structurally sound and does not have other detrimental effects on the product. Detrimental effects may include warping from high heat input in traditional welding, warping from reheat treatment, oxidation of machined surfaces, microstructural anomalies, and reduced mechanical properties. Micro laser welding has the potential to provide a solution to these issues by providing a low …

Aura-Visionpose: Creating Datasets For Vision-Based Pose Estimation, Mohanad Alameer

Masters Theses

"Spacecraft rendezvous is an integral part of many orbital missions, including active space debris removal (ADR) and in-orbit servicing, assembly, and manufacturing (ISAM). Traditionally, rendezvous missions rely mainly on manual ground-based control to perform rendezvous and docking. While this can be effective on an individual basis, it becomes less practical at scale. Autonomous vision-based methods can reduce reliance on human control, and may improve scalability, response time, and reduce the possibility of human error for both ADR and ISAM. This work lays the necessary groundwork for developing a machine learning (ML) model for autonomous rendezvous by creating a labeled image …

Near-Field Scan Method For Radiated Susceptibility Analysis And The Design And Optimization Of A Miniaturized Spiral Antenna For Ultra-Wideband Applications, Mckennan Edward Starkey

Masters Theses

"The work presented in this thesis consists of two separate topics. The first topic is a new method for the characterization of radiated susceptibility of electronic devices, while the second topic is on antenna design. The first topic proposes an approach to experimentally determine locations within an electronic system that are well coupled to external far-field radiators. This method is performed by using a differential magnetic field probe to sweep across the target device while measuring the total radiated power (TRP) produced by the device in a mode stirred tent. Scan locations where the TRP is larger than the background …

Cervical Ligament Systems In Sauropod Dinosaurs: What Support Is There?, Audrey Rose Williams

Masters Theses

"Sauropod dinosaurs, such as Diplodocus, have been the subject of numerous hypotheses about what ligamentous structures could have lifted and supported their long necks. Because the supportive tissues rarely fossilize, palaeontologists rely on osteological correlates on the bone to infer their nature. Options for supportive cervical ligaments in sauropods are mammal-style nuchal ligaments, avian-style interlaminar elastic ligaments, reptilian-style supraspinal ligaments, or some combination thereof. This study tested for the presence of a mammal-style nuchal ligament via histological and micro-computed tomography of posterior cervical hemispinous processes of Apatosaurus and Diplodocus, in addition to examining gross morphological features of the cervical vertebrae …

The Occurence Of Expansive Clay Soils In Illinois And Their Effects On Shallow Lightly Loaded Foundations, Greg James Gollaher

Masters Theses

"The damage caused to shallow foundations and slabs on grade by the shrink-swell activity of clay soils is well documented across the United States. There are local and national resources available that delineate areas that are problematic and areas that are not. These resources paint Illinois as an undemanding foundation environment. However, our experience differs from this. Our experience tells us that damage related to the shrink-swell activity of clay soils is widespread, and commonly severe causing not only cosmetic damage to structures and hard improvements but also affecting the serviceability and longevity of structures. My goal is to accurately …

Masters Theses

"This research explores the development of advanced steel grades manufactured through Castrip® twin-roll thin strip casting technology, with particular attention to non-grain-oriented electrical Si-Steels (NGOES) and carbide-free bainitic (CFB) steels. The Castrip® process offers a near-net-shape route for producing thin steel strips, which greatly decreases the number of processing stages, lowers energy demand, and reduces carbon dioxide emissions when compared with traditional steel production methods.

In the NGOES part of the study, several industrial Fe–Si steel compositions were cold rolled to final thicknesses ranging from 0.35 mm to 0.15 mm. These materials were then exposed to short-duration continuous annealing at …

Structured Decomposition And Efficient Adaptation For Scientific Data Movement: From Transfer Concurrency To Genomic Data Acquisition, Rasman Mubtasim Swargo

Masters Theses

"The end-to-end performance of scientific data movement is increasingly limited not by raw network capacity but by whichever resource along the path is momentarily slowest, a bottleneck that no single static configuration can track. This thesis argues that the right response is to decompose each problem along the resource or workflow axis where bottlenecks vary, adapt only the genuinely dynamic control variables at runtime, and make that adaptation efficient through utility-guided or offline-learned control rather than expensive online search. The thesis develops this principle through four systems of widening scope. AutoMDT decomposes a transfer by operation, assigning separate concurrency levels …

Moth Assemblages Of Fort Leonard Wood, Missouri, Kimberly Anne Steese

Tracing The "Growth Of The Poet's Mind" In The 1850 Version Of The Prelude, Karen F. King

Masters Theses

This work compares the 1805 and 1850 versions of William Wordsworth's autobiographical epic The Prelude to reveal that the revisions he made evidence his poetic growth. Critical scholarship has long discussed the poet's revisional habits, offering various rationales for his motivation and often dogmatically choosing a preferred version based on those assumptions. This paper first addresses these perspectives, then examines the structural details of Wordsworth's revisions through analysis of significant events in the poet's life that he relates in the epic, his "spots of time". Finally, I discuss the role of imagination as an influencer on the poet's growth. Although …

Beheld To Behold: A Rhetorical Theology Of Otherness In Acts, Hannah E. Gross

Masters Theses

The phenomena of otherness foundationally grounds this work. A micro-concept of Martin Buber’s I and Thou Theory, otherness is central to this study particularly as it is rhetorically situated in the work of Acts. The research draws from ideological criticism to produce a rhetorical theology. Findings uncover two primary relational dynamics of otherness: (1) God to the believer to the unbeliever and (2) God to the believer to the believer. These constructions of dialogical engagement in Acts are donned witness and withness, offering keen insight on a rhetorical theology of otherness.

Examination Of Sportscasters To Understand The Key Overlapping Traits And Skills Exhibited, Jason Prill

Sustainability Without Sacrifice: Rethinking Convenient Eating For Young Professionals, Teresa E. Michael

Masters Theses

Young professionals want to eat more sustainably– but life gets in the way. Between long hours, limited budgets, and an overwhelming stream of content, sustainable choices often fall apart in favor of convenience. This research explores that gap between values and behavior, asking: How do young adults actually make food decisions, and how can we help those decisions become more sustainable without demanding perfection? To answer that, I grounded my work in a literature review focused on food literacy, convenience culture, digital media, and behavioral psychology. I also conducted three case studies of food-tech companies (Too Good To Go, Misfits …

Operation Evil Empire: The Strategic Weaponization Of Rhetoric In Psychological Warfare, Sabrina Marie Smith

Masters Theses

The Cold War redefined warfare around information, ideology, and perception. Victory depended less on territory and more on legitimacy. In 1983, Cold War tensions between the United States and the Soviet Union were extremely high. President Ronald Reagan’s “Evil Empire” speech emerged at a critical juncture, marking a pivotal moment when U.S. foreign policy embraced assertive ideological confrontation. The rhetoric of this speech did more than address the American public; it served as a strategic instrument aimed at weakening Soviet ideological cohesion. It became a turning point in U.S. Cold War rhetoric, targeting both the Soviet leadership and its oppressed …

In response, this thesis presents a research-informed interactive design solution: a two-part installation titled …

The Ultra Dilemma: Understanding The Impact Of Ultra-Processed Food, Cassia Elizabeth Brenning

Masters Theses

Ultra-processed food dominates the market, making up an estimated 73% of the national food supply and costing 52% less than healthier, minimally- processed alternatives (Ravandi et al). With such a large supply, there is a great demand to sell these products to consumers. Major food corporations rely on misleading labels, heavy marketing, and industry-funded research to manipulate consumers into buying more of their products. While these products are cheap, quick, convenient, and delicious, they are not components of a healthy diet.

This thesis argues that the best way to tackle the issue of ultra-processed food is by redirecting focus from …
