Design, Simulation, And Experimentation Of A Box Barge Model Under Asymmetrical Conditions, Kylie Sink

Senior Honors Theses

This study investigates the ability of numerical simulations to predict vessel motion responses under asymmetrical loading conditions. A raked barge model was designed, constructed, and tested in a towing tank to evaluate the response amplitude operators (RAOs) for heave, roll, and pitch under various wave conditions. The model included six internal compartments that allowed different flooding scenarios to be simulated in order to create asymmetric loading conditions. Experimental testing was conducted under head seas (0 degrees) and beam seas (90 degrees) with multiple wave periods.

A numerical model of the vessel was developed using GHS to generate predicted RAOs for …

A Planetary Health Approach To Address Food Insecurities In New Mexico, Mariah Kennell

Doctor of Nursing Practice Scholarly Projects

Food insecurity remains a persistent public health concern throughout New Mexico, impacting both rural and urban populations and contributing to significant health disparities. Limited access to affordable, locally sourced fresh foods exacerbates chronic disease burden and undermines community health. The purpose of this Doctor of Nursing Practice project was to conduct a comprehensive policy analysis to identify feasible state-level strategies to improve food access through strengthening local food systems. Using the Centers for Disease Control and Prevention POLARIS policy analysis framework, a structured evaluation of existing and potential state and community-level policies was conducted. The analysis incorporated stakeholder interviews with …

Popular Accountability And State Constitutional Law, Jonathan L. Marshfield

Vanderbilt Law Review

American constitutionalism operates against the backdrop of democratic processes, but the federal Constitution approaches democracy differently than state constitutions. The federal Constitution is built to fend off rash majoritarianism through checks and balances and siphoning accountability into a few highly mediated representative bottlenecks—elections for President and Congress. State constitutional structure is different. Through processes like judicial elections, the citizen initiative, referendum, recall, popular conventions, and elections for various executive offices, state constitutions reflect skepticism of wholesale representative democracy and trust in extant electoral majorities to participate in governance. This Article argues that state constitutional law should better account for this …

Effects Of Vitamin E Deficiency On Anxiety-Like Behavior In Zebrafish With Distinct Stress Coping Styles, Areem Zahid

Theses/Capstones/Creative Projects

Stress and anxiety disorders affect millions worldwide and represent a significant public health burden. Individual differences in stress coping style and antioxidant regulation contribute to variability in stress responsiveness and anxiety-related behaviors. Oxidative imbalance has been implicated in the neurobiology of anxiety, but its interaction with inherent stress coping phenotypes remains unclear. This study examined whether long-term dietary vitamin E deficiency alters anxiety-like behaviors in zebrafish selectively bred for proactive and reactive stress coping styles. Adult zebrafish were maintained on either a vitamin E–sufficient or vitamin E–deficient diet for five months, followed by behavioral assessment using the novel tank diving …

Immigrants: Neighbors Or Strangers? An Analysis On Christian Thought And Immigration, Mariah G. Rivera

Theses/Capstones/Creative Projects

This thesis examines the relationship between Christian thought and perspectives on immigration in the United States, particularly in the context of the current Trump administration, which is focusing heavily on restrictive immigration policies. It explores the historical relationship between religion and government through government commissions, as well as changes in key immigration policies such as the “sensitive locations” guidelines affecting enforcement at and near places of worship. Drawing on biblical scripture, the thesis identifies key themes of loving the stranger, assisting the vulnerable, and obeying governing authorities, all of which inform Christian interpretations of immigration.

Through analysis of national and …

Insights Into Androgen Receptor Allosteric Modulation By P,P'-Dichlorodiphenyldichloroethylene Binding At The Binding Function-3 Site And Site-Specific Binding Function-3 Mutations, Emanuel Aggeo Flores

Theses and Dissertations

One of DDT’s metabolites, p,p’-dichlorodiphenyldichloroethylene (DDE), has been classified as an endocrine disrupting chemical (EDC) due to its ability to interfere with hormone signaling by binding to nuclear receptors (NR) such as the androgen receptor (AR).

Structurally, the AR contains a ligand-binding domain (LBD) where endogenous steroids bind. Furthermore, the LBD contains a surface binding site known as binding function-3 (BF-3), which studies suggest exerts an allosteric effect on bound DHT when small, hydrophobic molecules bind.

Here, we present a study that examines how specific BF-3 site mutations and DDE binding affect steroid stability within the LBP utilizing computational methods. …

Using Behavioral Monitoring To Assess Activity Patterns And Welfare Indicators In Captive Black Howler Monkeys (Alouatta Caraya), Ramiro Gomez Iii

Theses and Dissertations

This study examined activity patterns and potential welfare indicators in captive black howler monkeys (Alouatta caraya) using behavioral monitoring techniques. A monogamous pair housed indoors at Gladys Porter Zoo was observed using focal sampling methods, and a species specific ethogram was developed to systematically record behavior. A total of 1,750 minutes of data were collected over one year. Observed behaviors were categorized into five groups: affiliative, agonistic, stationary, locomotion, and stereotypic behaviors. Activity budgets were calculated to determine the proportion of time allocated to each behavioral category. Results indicated that affiliative behaviors, particularly physical contact, dominated the activity budget, while …

Exploring The Role Of Video Games In Civil Engineering Education And K-12 Stem Engagement, Jillian S. Codron

Architectural Engineering

Civil engineering education has traditionally emphasized a linear progression from theory to application, with foundational concepts introduced in lecture before being reinforced through laboratory or design experiences. While effective for advanced learners, this approach can limit early engagement for K–12 students who may struggle to connect abstract principles to realworld engineering practice. This project examines the use of video games as interactive, feedback-driven environments for introducing civil engineering concepts and practices to younger learners in more exploratory and accessible ways.

The study pursues four primary objectives: evaluating the educational affordances of selected video games; examining how gaming experiences have influenced …

¿Salvar El Mundo O Las Notas? Mahō Shōjo En El Contexto De La Reforma Educativa Lomloe, Daniel Romero Benguigui

Journal of Roleplaying Studies and STEAM

La década de los 90 supuso la apertura cultural japonesa, pues sería cuando las producciones anime se realizaron para ser visionadas en el extranjero, lo que llevaría a la globalización de unas narrativas asentadas en la sociedad japonesa. Esto queda manifiesto en la distinción shonen/shojo, siendo el primero un producto dirigido, respectivamente, a una audiencia juvenil masculina o femenina, siguiendo la demografía nipona mediante una serie de temas y referencias que, para el resto de países y sus comunidades, no podían interpretarse del mismo modo, fomentando una lectura propia.

Un ejemplo de ello se localiza en Sailor Moon (1991), …

Investigating The Role Of The Fascia In The Development Of Fibrodysplasia Ossificans Progressiva (Fop), Liv Nevo

Honors Scholar Theses

Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder that primarily affects connective and muscle tissues. It is characterized by heterotopic ossification (HO), which is the formation of bone tissue where it does not normally form. HO can be triggered by physical trauma, infection, inflammation, or stress. The formation of HO leads to impaired muscle function and reduced patient quality of life. Concurrently, the loss of muscle function indicates there is an impairment in the ability of the muscle to regenerate effectively. The most common genetic cause of FOP is an arginine-to-histidine substitution within the type I bone morphogenic protein …

Exploring Stem Cell-Based Approaches To Ameloblast-Like Cell Development: Progress And Limitations In Enamel Formation, Ava L. Abruzzese

Honors Scholar Theses

Enamel is one of the most critical structural components of the tooth. As the outermost layer, it serves as a protective barrier, shielding the underlying dentin and dental pulp from physical trauma and mechanical forces. The formation and mineralization of enamel are regulated by specialized cells known as ameloblasts. Once enamel maturation is complete, these cells undergo apoptosis. Consequently, enamel lacks the capacity for natural regeneration after damage or erosion, which can result from various environmental factors. When enamel is compromised, current clinical interventions focus on preventing further deterioration rather than true regeneration. These approaches include the use of remineralizing …

Monastic Design: Recovering The Sacred, Thomas Larkin Derek Crompton

Architecture Theses

Throughout history, transcendental meaning has been woven into the very fabric of architecture to awaken and attune our souls toward a greater understanding of the inherent, unquantifiable aspects of life. Design elements such as light, material, proportion, and mystery were used as communicators of meaning rather than merely tools of utility. However, with the rise of positivism in the modern period, many transcendental elements of design were disregarded in favor of a more functionalist approach. The strategies employed by this approach influenced much of modern religious architecture and have resulted in many churches that lack the fundamental principle they claim …

Building On Memory: Towards A Digital Future Informed By Historical Theory, Lucas Laskow

Architecture Theses

This project synthesizes 2,000 years of architectural theory to establish an ethical framework for integrating artificial intelligence into contemporary design. The research culminates in “The Chandler,” demonstrating how AI can enhance, rather than replace, human-driven spatial and cultural values.

The assertion that human design is inherently superior to artificial intelligence relies on the flawed premise that intuitive leaps outweigh data-driven synthesis. Rather than diminishing the architect’s role, the evolution of AI demands that designers become ethical interpreters who ask the right questions. This project investigates how past architectural theorists, from Vitruvius’s foundational triad to Bruce Allsopp’s humanist return, provide a …

Architecture As A Camera: Utilizing Photographic Principles To Tell Stories Through Design, Ryan Gabriel Scherf

Architecture Theses

This thesis examines the relationship between memory, photography, and architecture as a framework for spatial design, framing memory as a fragmented phenomenon contingent upon light and time. Drawing on the theoretical work of Goffi, Barthes, and Bordeleau, it positions architecture as a temporal montage in which meaning emerges through layered absences, material “puncta,” and the interpretive gaps between fragments. Situated at the Botallack Mines in England, the project explores the intersection of photographic logic and industrial ruin by treating the site’s extractive history as a series of active fragments. Through compressed volumes and curated views, it translates photographic principles into …

From Radiance To Resonance: A Human-Centered City Between Geometry And Humanity: Reconciling Modernist Ideals With Human-Centered Design, Christen Zeetu Doe

Architecture Theses

This thesis investigates how architectural practice can shift from top-down, modernist planning paradigms toward an observational methodology grounded in lived experience. Engaging with the legacy of Le Corbusier’s Radiant City, it critiques the pursuit of universal order and efficiency that often suppresses the nuances of everyday life. Drawing from Georges Perec’s attentive documentation of mundane urban moments, the project develops a process of “moment mapping,” where spatial understanding emerges through observation rather than imposed form. These collected moments are then abstracted into architectural elevations and spatial constructs, translating temporal, sensory experiences into built form. The thesis is situated within a …

Celebrating Scholarship and Creativity Day (2018-)

Extremophiles are organisms that can survive in extreme environmental conditions, and their unique biological adaptations have gained attention for potential applications in cancer research. This paper explores how the molecular characteristics of extremophiles, such as enhanced DNA repair, resistance to oxidative stress, and structural stability, may be useful in improving cancer treatment strategies. A range of studies were examined to understand both direct and indirect roles of extremophile-derived compounds in oncology. Some research shows that compounds from organisms like Deinococcus radiodurans and extremophilic Streptomyces species can inhibit cancer cell growth, increase reactive oxygen species, and trigger apoptosis. Other studies highlight …

Keeping Track Of Time: Does Formal Education Of Temporal Symbols Refine People's Ability To Perceive Time?, Alyssa Gabrielle Smith

Undergraduate Honors Thesis Collection

While many studies find a relation between symbolic and nonsymbolic numerical abilities (e.g., Chen & Li, 2014), whether this relation is causal has been questioned. For example, does learning symbols refine nonsymbolic abilities (i.e., Refinement Hypothesis)? One study found that as children gained proficiency in their verbal counting abilities, their nonsymbolic numerical acuity increased (Shusterman et al., 2016), thus supporting the Refinement Hypothesis. As studies have found similar processing for numerical and temporal abilities (e.g., Walsh, 2003) and a similar relation between symbolic and nonsymbolic timing abilities has been found (e.g., Hamamouche & Cordes, 2020), it begs the question of …

Lipid Deposition In Beef Cattle, Kyra L. Elliott

Department of Animal Science: Dissertations, Theses, and Student Research

Both the amount and types of lipid deposition in beef cattle are key determinants of carcass value and meat quality. Amounts of intramuscular, subcutaneous, and visceral fat influence carcass grading outcomes, palatability, and composition traits that are important to beef producers as well as consumers. The objectives of this thesis were to: 1) compare beef grading camera estimates of intramuscular fat to amounts of chemically extractable lipid, 2) characterize the lipidomes of beef intramuscular fat, subcutaneous fat, and lean muscle using shotgun lipidomics, and 3) identify and characterize a novel genetic variant in cattle that may have important implications for …

Application Of High-Pressure Processing To Improve The Color Of Dark Beef, Kara Ann Reynolds

Department of Animal Science: Dissertations, Theses, and Student Research

Deviation of beef from the bright cherry-red color preferred by consumers is often discounted or discarded at retail, resulting in substantial annual economic loss to the beef industry. One such deviation is dark cutting beef, which is characterized by a darker lean appearance that is undesirable to consumers and often rejected. Similarly, beef from mature cattle tends to exhibit a darker surface color, which can also reduce consumer acceptability. High-Pressure processing (HPP) has been investigated as a strategy to improve the color of dark cutting beef. Previous studies have focused on identifying pressure levels and holding times that optimize color …

Preclinical Animal Modeling To Investigate Redox-Mediated Molecular Dysfunction In Traumatic Brain Injury, Brandon Z. Mcdonald

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Impacts associated with traumatic brain injury (TBI) induce a multitude of neurological morbidities mediated by a spread of biochemical dysfunction. Redox stress is a significant contributor to TBI pathophysiology and several redox stress markers have substantial evidence to support their role in diagnosing preclinical and clinical TBI. However, there is a critical need to verify their translational utility through correlations with behavioral, imaging, and molecular modalities. In chapter two, we examined the therapeutic efficacy of an antioxidant treatment (NPC3) using a controlled cortical impact (CCI) mouse model of TBI. NPC3 alleviated glial expression and reactivity while influencing the expression of …

The "Evil Forest" As Threshold: A Computational Eco-Feminist Study Of The Forest In Nigerian Fantasy, Cynthia O. Mbagwu

Department of English: Dissertations, Theses, and Student Research

This study examines the representation of the “evil forest” in Nnedi Okorafor’s Zahrah the Windseeker and Ukamaka Olisakwe’s Don’t Answer When They Call Your Name, arguing that the forest functions as a liminal threshold that catalyses female transformation. Combining close reading with computational tools like TF-IDF keyword extraction in Ruby and sentiment analysis using VADER, the project investigates how pre-colonial and colonial connotations of the “evil forest” are re-imagined in contemporary Nigerian fantasy fiction. By segmenting each narrative into pre-liminal, liminal, and post-liminal phases, the study tracks shifts in sentiment toward the forest and correlates them with thematic developments …

Factors Affecting The Efficacy Of Free Choice Vitamin & Mineral Supplementation Programs, Tanner K. Wansing

Department of Animal Science: Dissertations, Theses, and Student Research

While free choice vitamin and mineral supplements are widely used within the cow/calf sector, large knowledge gaps exist around the proper management of those supplements. This thesis discusses two factors affecting the efficacy of supplementation. The first interest was the stability of vitamin A when stored with a common free choice mineral supplement. This research addressed a critical data gap by generating information on vitamin A stability within the beef industry, as current data are predominantly based in the swine industry. Vitamin A was discovered to be stable until 4 months of storage regardless of storage conditions, whereas after 4 …
