Embodied River: Deliberate Unbuilding In Post-Dam Landscapes, Travis Kelley

Masters Theses

This thesis explores the possibilities and challenges that legacy hydro-powered dams and mill complexes offer. Through historical and contemporary analysis of New England’s 14,000 dams and of a particular site in Maynard, Massachusetts, the research delves into the factors that make these interventions so challenging. It begins from an assumption rooted in the ethical and environmental imperative to remove or modify legacy dams, which are those built for a purpose that is no longer being utilized, and rejects the existing binary of “remove” vs “preserve,” which is the dominant narrative in the dam removal conversation as it exists in 2026. …

The Message Within The Show: A Cultivation Study On The Impact Of Children's Television On Perceptions Of The Family, Ashley Bowes Fletcher

Masters Theses

The purpose of this qualitative research study was to explore the impacts of popular early 2000s children’s television shows on now-adult viewers’ perceptions of the nuclear family. The problem is that current scholarly literature had not addressed how early 2000s television shows have impacted the perception of a traditional nuclear family’s role in society. This study sought to identify the views currently held by the participants regarding the importance and roles of the nuclear family. The study also sought to identify the participant’s perceptions of the portrayals of the nuclear family in specific early 2000s children’s sitcoms. Through a variety …

Adam, The First Scientist: Unlocking The True Foundation Of Scientific Thinking, Thomas E. Lohman Jr.

Masters Theses

This thesis investigates the complex relationship between scientific thought and theological perspectives, proposing that God breathing life into Adam symbolizes a full divine inspiration for both scientific and theological understanding. The perceived conflict between science and theology arises from a shift in human thinking at the fall, which altered humanity's ability to rightly grasp both realms. After this crucial event, science shifted to a more naturalistic approach, while theology often downplayed God's sovereign power over creation.

The alterations to the original functions and purposes of science and theology have led to a fragile relationship between the two. According to Scripture, …

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 …

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 …

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 …

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

Masters Theses

This thesis investigates the distribution of invasive Japanese knotweed across Michigan.

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 …

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 …

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 …

Metabolic And Replicative Constraints On Pathogen Virulence: Isoleucine Catabolism In Shigella And Comparative Tanapoxvirus Replication In Cell Cultures, Benecia Angelica

Masters Theses

Pathogens survive by balancing metabolic demands with environmental challenges that shape their virulence and adaptability. Shigella flexneri, a highly infectious human pathogen responsible for severe diarrheal disease worldwide, utilizes branched-chain amino acid (BCAA) metabolism to withstand stress conditions encountered within the host environment. In this study, we explored the Shigella isoleucine catabolism pathway by knocking out four genes in the S. flexneri isoleucine catabolic pathway (ilvE, fadA, fadD, and acnB) and examining their metabolism and virulence. We found that the ilvE and acnB mutants displayed reduced metabolic activity and smaller plaque size, while the fadD mutant showed decreased invasion. In …

The Intermediate State: Scriptural, Philosophical, And Scientific Evidence For Conscious Existence After Death, Timothy R. Perry

Masters Theses

This thesis examines whether Scripture and supporting evidence affirm that believers enter the immediate presence of Christ in a conscious and possibly embodied state prior to the resurrection. It argues that compelling scriptural, scientific, and philosophical evidence supports the doctrine that believers enter the presence of Christ immediately after death, in a conscious and possibly embodied state until the final resurrection. The study employs a multidisciplinary argument drawing upon biblical exegesis, philosophical reasoning, and relevant scientific insights from the emerging field of near-death experiences. This study uniquely frames the intermediate state as an apologetic issue, offering hope to Christians who …

They Write Themselves: Romancing The Vampire Of Lighthouse Landing, Dezi Vaile

Masters Theses

Many fantasy creatures have dark pasts; supernatural, often disturbing, stories that have been tossed in a sauce of romance to appeal to a wider palette. While vampires are typically regarded as creations of nightmares, these creatures of the night have been no exception to this cycle. Although legends of blood suckers far predate the birth of Bram Stoker, Dracula is arguably the most enduring and important example of vampire literature. By beginning with Dracula, alongside earlier works like The Vampyre and Carmilla, we will track what has and has not changed within the genre of vampire literature. With the passage …

The thesis aims to provide insight to create characters that will make a difference in the story and …

Writing From The Rift: Queer Temporality And The Refusal Of Resolution, Daniela Ruiz Perez

Masters Theses

This thesis develops a phenomenological method for reading speculative literature as a site where queer ecological temporality is experienced rather than explained. Working with Annihilation (2014) by Jeff VanderMeer, The Day of the Triffids (1951) by John Wyndham, and Undrowned: Black Feminist Lessons from Marine Mammals (2020) by Alexis Pauline Gumbs, the project treats reading as a bodily practice shaped by forms of attention. Texts are not interpreted for stable meaning and instead I remain with moments where resolution is withheld. The work is informed by a Marxist attention to how capitalist time organizes labor, productivity, and value, and how …

Variances In Power Output Of Female Athletes During The Menstrual Phases, Julia L. Allen

Feeding Performance And Survival Of Louisiana Poeciliid Fishes Exposed To Residential Wastewater Effluent, Jonathan Chapman

Masters Theses

Mosquitoes are a primary transmitter of vector-borne disease, and their larvae can thrive within shallow pools of stagnant water. Rainwater drainage ditches are a common sight in many communities, and in Louisiana, they are dually used as outlets for onsite residential wastewater discharge in neighborhoods disassociated from municipal sewage treatment. However, when discharge systems malfunction, the water becomes uninhabitable to mosquito predators, allowing mosquitoes to thrive. This research examines the predation performance of mosquitofish (Gambusia affinis), sailfin mollies (Poecilia latipinna), and least killifish (Heterandria formosa), the primary biological control agents utilized to combat mosquitoes within ditch communities. Individuals were captured …

The Role Of Isotocin In Female Zebrafish (Danio Rerio) Reproductive Behavior And Its Implication For Intranasal Oxytocin Therapy In Humans, Katelynn M. Benge

Masters Theses

In the past several decades, oxytocin has been colloquially termed the “cuddle hormone,” due to its role in pair-bonding and monogamy (Carter et al., 1992). In addition to being used experimentally for psychological disorder, it has also been used in couple’s counseling settings (Anagnostou et al., 2014; Domes et al., 2016). The outcomes of this research reveal mixed results, creating a need for further research in the topic to understand the exact mechanisms by which oxytocin works in the brain to induce this prosocial response. This study sought to address this deficit through the zebrafish animal model. The zebrafish serves …

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 …

Calcium Based Carbon Negative Fillers And Additives: Effects On Hydration And Performance Of Low-Carbon Cement Systems, Smita Bhowmick Shithi

Masters Theses

Cement production is a major source of global CO₂ emissions creating an urgent need for carbon-negative fillers and functional additives that lower clinker use while maintaining cement performance. This thesis investigates the effects of organic mineral salts as fillers and additives on cement hydration, fresh properties, compressive strength and pore structure. In the first study, ordinary Portland cement (OPC) was partially replaced with calcium carbonate or calcium oxalate to enable a direct comparison under controlled particle size distribution (PSD). Rheology, flowability, hydration kinetics, phase evolution, mechanical performance and water absorption were evaluated. Calcium carbonate promoted early hydration through nucleation and …

Analyzing Sleep Architecture And Brain State Transitions Via Hidden Markov Models On Fmri Data, Brileigh Jay Cates

Masters Theses

Sleep is associated with systematic changes in brain activity and functional connectivity observable in functional magnetic resonance imagining (fMRI) signals. Because subjects often fall asleep during resting-state experiments, the absence of vigilance monitoring can confound the interpretation of resting-state dynamics. Although electroencephalography (EEG) is the gold standard for sleep staging, simultaneous EEG-fMRI acquisition is not always feasible.

This study investigates whether sleep stages can be inferred directly from fMRI using a probabilistic latent-state framework. Hidden Markov Models (HMMs) are applied to blood-oxygen-level-dependent (BOLD) time series to identify latent brain states and their temporal transitions. Inferred states are aligned with EEG-derived …
