Correlations Between The Army Combat Fitness Test (Aft) Events And The 12-Mile Ruck March, Isabella Huner Cruz

Masters Theses

The Army Fitness Test (AFT) consists of maximum deadlift, hand-release push-ups, sprint-drag-carry, plank, and a 2-mile run and is used by the United States Army to assess a soldier’s ability to meet occupational demands. The AFT is designed to ensure soldier readiness and maintain physical and mental well-being. In addition to the AFT, soldiers are often tasked with a loaded ruck march across various distances. Loaded ruck marches are a frequent occurrence in the Army as a mode of testing, training, and combat. Due to the AFT’s role in predicting soldier task performance, it would be valuable to identify any …

From Christology To Ontology: A Diachronic And Exegetical Evaluation Of A Maximalist Sacramental Interpretation Of John 6:51–58, Andrew R. Johnson

Masters Theses

John 6:51–58 occupies a central place in the debate regarding the ontological nature of the Eucharist, frequently serving as a primary scriptural warrant for sacramental realism such as articulated by the Council of Trent as it concerns the dogma of transubstantiation within the Roman Catholic tradition. This thesis conducts both an evaluation of historical reception and a critical exegetical analysis to determine whether the Evangelist’s primary intent was to establish sacramental doctrine in this passage or to further develop already pervasive Johannine soteriological and christological themes.

Methodologically, this study bridges the gap between historical reception and synchronic exegesis. The first …

Trauma, Myth, And Sacred Memory: How Narrative Gives Form To Suffering, Theology, And Meaning, Jacob M. Tannehill

Masters Theses

This thesis explores the relationship between trauma, myth, and narrative meaning through academic and creative works. Drawing upon trauma theory, cultural memory studies, and mythopoeic fantasy, this thesis examines how communities remember catastrophes, preserve identity, and struggle to transform suffering into coherent narratives. The critical portion focuses on J. R. R. Tolkien’s account of Númenor’s destruction in The Silmarillion, reading the Downfall as a model of cultural trauma whose meaning persists through inheritance and contested narration. The creative portion, drawn from excerpts of The Adia, extends these concerns into a mythic world in which language, memory, and theological inheritance shape …

Factors Associated With Vaping Frequency Among University Students, Oluwatosin Marylyn Oduneye

Masters Theses

Electronic cigarette use among university students is a growing public health concern, with approximately 20-25% reporting current use. Despite extensive research on vaping initiation, factors associated with vaping frequency among established users remain understudied. This study examined stress-coping mechanisms, peer influence, and health risk perceptions as predictors of vaping frequency, guided by Bandura's Social Cognitive Theory (SCT). A quantitative cross-sectional survey was administered via Microsoft Forms to 399 university students aged 21-25 with recent vaping experience, recruited nationally through campus flyers and online platforms. Multiple linear regression was conducted in SAS OnDemand for Academics, with stress-coping, peer influence, and health …

The Use Of Tactile Stimulations To Mitigate Somatic Anxiety Responses: A Pilot Study, Abigail C. Robbins

Masters Theses

Anxiety is the body’s response to detected danger or stress. Physiological responses include shallow breathing, increased heart rate, sweating, shaking, and muscle tension. Roughly 33.7% of the population experiences anxiety, with approximately 40 million adults in the United States being affected by the disorder. Anxiety can create severe personal, social, and economic burdens. Traditional treatments of anxiety disorders such as medication and psychotherapy can be effective, but present multiple barriers such as cost, accessibility, and side effects. As a result, there is a growing industry for non-invasive, low-cost solutions that can help individuals regulate their physiological anxiety responses and reduce …

Experimental Measurements Of The Forces Acting On A Submerged Beam Using High-Speed Videography, Madelyn Burrell

Masters Theses

The interaction of structures and fluids is highly relevant in many fields but difficult to accurately and reliably characterize. This study demonstrates a novel method of simplifying such problems by analyzing the structural deformations directly, without needing to explicitly solve for the fluid aspect. Six cantilever beams of varying properties were submerged in still water and released from an initial deflection at the free end: the cases consisted of three beam shapes (one of uniform width, one with a narrower free end, and one with a wider free end), with an end mass attached or detached. High-speed videography was utilized …

In Vitro Modeling Of Macrophage And Cd8+ T Cell Activation: Evaluating Immortalized Cell Lines For Use In Undergraduate Immunology Laboratories, Lucy Groothuis

Masters Theses

The immune system is a complex, highly coordinated network of cells and signaling molecules that protects the body from infection and disease. Immunology is therefore a fundamental component of undergraduate education for students pursuing careers in medicine and biomedical research. Despite its importance, many undergraduate immunology courses lack a laboratory component. To address this gap, we developed an open-access immunology laboratory manual and evaluated its ability to generate meaningful data using primary murine cells and commercially available cell lines. Given the cost and logistical constraints of using mouse models in an undergraduate laboratory setting, we evaluated whether immortalized cell lines …

Glp-1 Receptor Agonists And Disordered Eating: Clinical Indicators And Patient Narratives, Samantha E. Schulz

Masters Theses

Introduction: The use of the medication, GLP-1 receptor agonist (GLP-1 RA), for weight loss has increased exponentially in the United States over the past decade. The continuing rise in demand for the use of GLP-1 RAs for weight loss justifies the need to better understand the physical and psychological effects that can occur with significant weight loss. By combining a standardized screening tool for eating disorder (ED) risk with narratives from patients undergoing GLP-1 RA treatment for weight loss, this study examines associations between GLP-1 RA use patterns and risk of ED and explores patient experiences, including the role of …

Improving Human Visual Search: Enhancing Lung Cancer Nodule Detection In Medical Images, Christopher Khajira

Masters Theses

Human visual search involves the identification of relevant signals within information-rich environments, which is a fundamental problem in visual perception. While detection accuracy and response time are commonly used to evaluate performance in visual search, these measures do not reveal the underlying cognitive and computational structure that produces observable behavior. A key challenge lies in distinguishing between competing processing architectures, particularly in complex visual domains where different models can produce similar behavioral outcomes. This study addresses this challenge by developing a computational experimental framework for analyzing visual search behavior using System Factorial Technology (SFT). The experimental framework integrates naturalistic medical …

Comparative Behavioral Impacts Of Neuroactive Pharmaceuticals On Crayfish Locomotion, Grace Elizabeth Smith

Masters Theses

Pharmaceuticals are increasingly recognized as contaminants of concern in aquatic ecosystems, often entering waterways due to incomplete removal by wastewater treatment plants. Despite frequent detection, the effects of these compounds on non-target, neurochemically sensitive organisms such as crayfish remains underexplored. Gabapentin, an anticonvulsant that binds to presynaptic voltage-gated calcium channels and reduces excitatory neurotransmitter release, is one such emerging contaminant. Given crayfish’s ecological importance and sensitivity to neuroactive substances, exposure to gabapentin may disrupt key behaviors such as locomotion. To place gabapentin’s effects in context, we also examined escitalopram (Lexapro), a selective serotonin reuptake inhibitor that elevates synaptic 5-HT, and …

Two communities, Michigan City and Chesterton, serve as the primary study areas along with the park itself. Qualitative methods, centered …

Haunted By A Cheap Ghost: Objects As Identity, Caitlin Zachow

Masters Theses

I am haunted by a cheap ghost, surrounded by inherited memories that are not my own, preserved in heirlooms that leave little room for me to create souvenirs of my own experience. In response, my practice centers on the personal significance of collections as outward expressions of identity, personality, and lived experience. Rooted in themes of Midwestern Americana, this exhibition presents narrative tableaus and curated collections that examine how personal identity is constructed through objects of memory, and display.

Informed by research into the history of kitsch, Sigmund Freud’s concept of the uncanny, and the “outmoded,” my work considers how …

Capacity Reduction Factors For Steel Beam Ends With Holes, Kevin Saleh Makubuli

Masters Theses

The presence of holes at steel beam ends can decrease the nominal resistance (capacity) of beam ends. Codes such as AASHTO LRFD and AISC include equations for evaluating the nominal resistance of steel beam ends. While these equations are appropriate for as-designed beam ends, they may not apply to deteriorated beam ends, such as those with holes. Thus, this study aims to develop procedures to calculate the capacity of steel beam ends with holes. First, the FEA of an as-designed beam is performed for capacity evaluation (numerical result). The latter is compared with the analytical result (as-designed beam capacity) to …

The Trade-Off Between The Fear Of Judgment (Stigma) And The Intention To Engage With Ai-Driven Hiv/Aids Information: Evidence From Bangladesh And Nigeria, Abdullah Mohaimen

Masters Theses

This study explores the relationship between Fear of Judgment (FOJ), understood as perceived stigma, and Intention to Engage (EI) with an AI-driven chatbot providing HIV/AIDS information. Stigma often discourages individuals from seeking information or discussing sensitive health issues, creating barriers to prevention and education. AI chatbots offer a potential solution by enabling anonymous, accessible, and non-judgmental interactions. This study examines whether FOJ reduces users’ willingness to engage with such technology and whether cultural context shapes this relationship. Data were collected from young adults in Bangladesh and Nigeria (N = 56) through an anonymous online survey using a simulated chatbot, Lifeline. …

Distribution Mapping And Modeling Of The Invasive Japanese Knotweed, Jossalyn Rogalski

Masters Theses

This thesis investigates the distribution of invasive Japanese knotweed across Michigan. This plant poses significant challenges to land management due to its rapid growth, environmental impacts, and difficulty of removal once established. Using geographic information systems (GIS), remotely sensed data, and secondary environmental datasets, this research maps current infestations and analyzes key factors influencing the species’ growth and dispersal, such as soil composition, hydrology, land use, and a range of environmental variables, including climatic (annual mean temperature, temperature seasonality, annual precipitation, precipitation seasonality), elevation, vegetation and hydrological indices (NDVI, EVI, NDWI), percent tree cover, and distance to roads. Spatial analysis …

Coloniality In Blue, Aaron Rosa

Masters Theses

This research explores Puerto Rican identity through a diasporic lens. I investigate thematic underpinnings of colonialism and sovereignty in Puerto Rico, focusing on the intersectionality of colonial history, gender, memory, objectification, identity fragmentation, cultural resilience, narrative reclamation, and the color blue through autobiographical anecdotes. The recounting of these stories is interpreted through a variety of materials linked to my relationship with their colonial histories.

Through these relationships, I have created sculptures that reflect the materials to which these bonds are linked. Through the reflection of 451 years of colonial rule, my goal is to interweave the symbology of these materials …

Transformer Vulnerability To Geomagnetically Induced Currents Using Layered Soil Conductivity Models, Junior A. Sterling

Masters Theses

Geomagnetically induced currents (GICs) pose a significant threat to modern power transformers connected to long high-voltage transmission systems, particularly in regions with low subsurface electrical conductivity. During geomagnetic disturbances (GMDs), time-varying magnetic fields induce surface electric fields that drive quasi-DC currents through grounded transformer neutrals. These currents can bias transformer cores, leading to saturation, waveform distortion, and potential system instability. Despite extensive research, the role of regional Earth conductivity in shaping electric fields and transformer response remains an area requiring deeper investigation.

This study analyzes how contrasting Earth conductivity profiles influence GIC magnitude and transformer saturation risk using two representative …

Does The Party Label Matter? Partisanship, Election Timing, And Ballot Drop-Off In Municipal Elections, Joelle Francis Whitaker

Masters Theses

This project examines if party labels drive participation in municipal elections. Progressive Era reforms removed partisan labels in attempts to weaken party machines and simplify local governance. Many cities continue to implement these reforms today. However, existing research suggests that party labels provide important informational and mobilizing cues that should increase turnout, especially in low-information elections. Using a comparison of four Michigan municipalities, this paper evaluates how partisan and nonpartisan systems shape local election turnout. The results show that the relationship is more complicated than expected. While party labels will still matter for how voters make decisions, election timing emerges …

Transient Mitigation In Dual Active Bridge Converter Using An Auxiliary Converter With High-Frequency Selective Control For Load Step-Down Condition, Sachith Dilshan Wijesooriya

Masters Theses

Dual Active Bridge (DAB) converters are widely utilized in applications such as electric vehicles, renewable energy systems, and solid-state transformers due to their high efficiency, galvanic isolation, and bidirectional power transfer capability. However, during rapid load transitions, DAB converters frequently exhibit significant output voltage overshoot and prolonged settling times, which increase device stress and adversely affect system reliability. This thesis proposes an auxiliary-circuit-based transient mitigation method to address these limitations. The auxiliary circuit, implemented as a bidirectional Buck–Boost stage, operates in Boost mode during load step-down events to absorb excess energy and suppress the resulting voltage overshoot. The design of …

Extremum Seeking Compensation And Quantification Of Position Sensor Offset Error In Speed-Controlled Permanent Magnet Synchronous Motors, Tessa Biondo

Masters Theses

Position sensor offset errors present a persistent challenge in speed-controlled permanent magnet synchronous motor drives operating under field-oriented control. Even small, constant offsets in the measured rotor position can reduce torque effectiveness, requiring increased current and voltage demand to maintain the commanded speed and resulting in degraded speed regulation performance across a range of operating conditions. These effects are particularly problematic in speed-controlled systems, where speed loop dynamics cause increased electrical effort and limit overall performance. Many existing detection and compensation approaches are either dependent on the system model, require offline calibration, or are primarily designed for torque-controlled operation. This …

Trust And Legitimacy In Police Public Encounters: An Analysis Of The 2018–2022 Police Public Contact Survey, Brooke Campbell

Masters Theses

This study examines how interaction-level characteristics in police-public interactions shape perceptions of trust and legitimacy. Using the Police Public Contact Survey (PPCS), interaction characteristics were investigated to see if they shaped perceptions of legitimacy and trust that the public has toward policing. Logistic Regression was used to see if factors such as contact duration, contact type, and time of day were associated with perceptions of police behavior, satisfaction, bias, future willingness to contact the police, and adequacy of the time spent. Drawing on legitimacy as the guiding framework, the PPCS years 2018, 2020, and 2022 (United States Bureau of Justice …

Conventional Vs. Regenerative Apple Orchard Management In Michigan, Anthony Poynter

Masters Theses

This study compares the variables and outcomes of a conventional apple orchard and a regenerative apple orchard production system in Kent County, Michigan. The premise is that conventional agriculture relies on high-input systems characterized by synthetic fertilizers, pesticides, herbicides, and fungicides, while regenerative agriculture focuses on long-term soil health, biodiversity, and ecological processes. These differences are important as soil degradation, nutrient loss, and environmental impacts are becoming too significant to ignore. Most research on alternative ways to farm, such as regenerative practices, is focused on annual crops, while perennial orchard systems, especially in the Great Lakes region, have gained limited …

Evaluating The Effects Of Multi-Functional Stations, Direct, And Motivational Messaging On Paper Cup Recycling, Madisyn Wynter Slater

Masters Theses

According to the Environmental Protection Agency (EPA), within Michigan alone, the municipal solid waste that has been collected in landfills contains approximately 31.5 million dollars in mixed paper and 18.8 million dollars in plastics (U.S. Environmental Protection Agency [EPA], 2016). One important aspect of recycling awareness is the impact that recycling has on the world. Whereas products like paper and plastic are accepted in recycling programs, any lined paper products (e.g., soda cups and to-go hot cups) are typically not accepted and therefore go to a landfill. Recent technology that can separate the lining from the paper, however, enables paper-lined …

Increasing Accuracy Of Mapping Local Climatic Zones Using Building Height And Spectral Unmixing, Ian Douglas Stauffer

Masters Theses

Local climatic zone (LCZ) classifications are traditionally done using reflectance, population data, and often climatic data. The goal of this research is to utilize Google’s new “Open Buildings Temporal v1” building data set as well as “spectral unmixing”. With the objective of testing, assessing, and implementing this data set into the workflow of LCZ mapping. After testing the quality of the data against a validated LiDAR data set from the same year as a given “Open Buildings Temporal v1” band, I implemented it into the Random Forest machine learning process. Secondly, I justified the use of spectral unmixing as a …

Changing Dynamics Of Microbial Communities At A Hydrocarbon Contaminated Site And Methanogenic Interactions With Iron Minerals, Jakob Sell

Masters Theses

Microbial life is not only ubiquitous but also plays a critical role in the geochemical makeup of our planet. While researchers have long studied easily culturable aerobic microbes, the influence of anaerobic life on soils and mineral cycling is less understood. Notably, knowledge about interactions between anaerobic microbes and inorganic elements such as iron has progressed with the discovery that magnetite influences how anaerobic archaea carry out methanogenesis. To better understand anaerobic bacterial metabolisms and how they interact with minerals and subsurface hydrocarbons, we extracted 16S rRNA genes from two adjacent subsurface petroleum plumes, sequenced the DNA, and analyzed it …

Scholarship As A Means For Musical Performance: An Exploration Of Johannes Brahms Violin Sonata In G Major, Op. 78, Josh Zallar

Masters Theses

Developing a quality musical performance is a complicated and time-consuming endeavor. Endless hours are spent learning a musical instrument, developing technique, and growing into a mature sound. Learning the notes, rhythms, dynamics, and basic musical markings of a score compound this task, not to mention the preparation for performing by managing nerves, among other areas of concern. Amidst the undoubtedly enormous amount of work, however, often focus gets lost. Musicians forget that, despite the inherent fact that our inner voice is heard when we perform, that it is ultimately the composer whose voice and musical meaning must be conveyed in …
