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 …

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 …

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 …

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 …

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 …

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 …

Consensus Guidelines On Inferior Petrosal Sinus Sampling: A Guideline From The Society Of Vascular And Interventional Neurology Guidelines And Practice Standards Committee, Farhan Siddiq, Hunter Brooks, Esra Demirtas, Ibrahim Ahmad Bhatti, Sami Al Kasab, Adam De Havenon, Robin Novakovic, Ossama Y. Mansour, Cynthia L. Kenmuir, Ameer E. Hassan

School of Medicine Publications

Background: Bilateral inferior petrosal sinus sampling (BIPSS) is the gold-standard test to distinguish Cushing disease (CD) from ectopic adrenocorticotropic hormone (ACTH) secretion when biochemistry confirms ACTH-dependent Cushing syndrome and pituitary magnetic resonance imaging is equivocal. However, practice varies widely between centers, leading to false negatives, misinterpretation, sampling errors, and avoidable risk. Neurointerventionalists performing BIPSS have lacked dedicated, procedure-focused guidance.

Methods: Using the Society of Vascular and Interventional Neurology Guidelines and Practice Standards framework, a multidisciplinary panel (endocrinology, interventional neuroradiology, and endovascular neurosurgery) performed a systematic review through August 2025 and developed recommendations graded by class of recommendation and level of …

Evaluating Modern Neural Network Architectures For Suicide Prediction, Kyle Brown

Master's Theses

Suicide remains a leading cause of death among adolescents despite more access to healthcare information than ever before. Medical professionals struggle to make accurate diagnoses and catch warning signs with the overwhelming amount of data available. Machine learning algorithms, including neural networks, have previously been employed for this task, yet it remains an understudied domain.

This research aims to evaluate the capabilities of Multi-Layer Perceptron (MLP) and a selection of its successors, ResNet and MLP with a category embedding layer, at the task of predicting suicidal ideation among high-school students. This research finds ResNet to be the most capable at …

Redeveloping Mississippi: A Case Study On Brownfields In Central & Southern Mississippi, Sahrah R. Yeroozedek

Master's Theses

Brownfields, or properties that are or possibly are contaminated with dangerous materials, represent a common obstacle for communities in Mississippi. The real or potential presence of contaminants at these sites often deters investors due to costly cleanup requirements (EPA, n.d. -b). The Environmental Protection Agency (EPA), through its Brownfield Revitalization Program, implemented guidelines for covering the costs and labor associated with the remediation of these properties. The EPA is not, however, responsible for redevelopment that supports long-term environmental and economic sustainability. Although the EPA maintains inventories of all Brownfields, there is also no comprehensive database of Brownfields and their current …

A Unified Framework For Distributed And Resource-Aware Plant Disease Detection Using Federated And Adaptive Hybrid Deep Learning, Ticauris S. Stokes

Master's Theses

Plant disease detection in precision agriculture must operate under significant computational constraints, particularly in low-resource (LR) environments such as unmanned aerial vehicles (UAVs) and edge devices. While LR models enable efficient real-time inference, they often lack the representational capacity required to accurately detect complex disease patterns. In contrast, high-resource (HR) models achieve superior detection performance due to their deep architectures but are computationally expensive and unsuitable for direct deployment in resource-constrained settings. This fundamental trade-off between efficiency and accuracy presents a major challenge for practical agricultural monitoring systems.

To address the distributed nature of agricultural data, federated learning (FL) is …

Agency Fact-Making, Haiyun Damon-Feng

Articles

Modern administrative-law scholarship, theory, and doctrine generally conceptualize agencies as engaging in three primary functions: rulemaking, enforcement, and adjudication. This understanding of agencies has informed deep debates surrounding the power, independence, and constitutional legitimacy of the administrative state. But the prevailing account is incomplete. It overlooks a fourth core function of the administrative state: its fact-making, or epistemic, function. Across the administrative state, agencies create and disseminate information in ways that are uniquely comprehensive and uniquely powerful. Agencies’ epistemic outputs include the census generated by the Census Bureau, repositories of public-health information maintained by the Centers for Disease Control and …

Simulated Battles, Real Lessons: Analyzing The Impact Of The U.S. Navy’S Fleet Problems On Battle In The Pacific War, Jackson T. Volkert

Master's Theses

The historiography of the Pacific Theater of World War II is thorough in regard to its coverage of the war itself. The technology, doctrine, and personnel practices of both the Imperial Japanese Navy and the United States Navy are well understood by historians in the field. In addition to this, a less thorough but still healthy understanding exists as to how the belligerents in question adopted the methods and tactics they used on the battlefields of the Pacific. What currently exists in this field of study places more analytical emphasis on the cultural and strategic level impacts of the interwar …

"Ostracized As We Are With God": Mina Loy's Anti-Career And The Search For Originality, Peyton L. Phillips

Master's Theses

Among many modernist artists, Mina Loy remains one of the most complex and allusive. Recent posthumous exposure of Loy's life and work adds to this precarity. A significant piece of Loy's life that is especially complex to contemporaries is her time spent writing. By establishing Loy's subjective relationship with her Victorian upbringing, this paper seeks to show examples of its influence on her search for originality. Mainly, the paper examines Loy's concept of originality, where that concept may have come from, and how it is reflected in her literature. The paper analyzes three of Loy's literary works, her poems "Virgins …

Volunteer Spotlighting: Costly Signaling To Promote Volunteerism, Clyde A. Raible V

Master's Theses

Prosocial behaviors, because they are initially costly and do not guarantee a direct benefit to the actor, can nonetheless increase social status by signaling a willingness to incur cost on behalf of another. Given this signal value, nonprofit organizations may be able to leverage this knowledge to increase donations, such as through the provisioning of attention to, and recognition of, volunteers through social media. I predicted that the costliness of spotlighted behavior and the target signal clarity (i.e., individual vs. group spotlight) would interact with participants’ dispositional dominance and prestige-based status motives to influence volunteerism interest. To explore these associations, …

The Impact Of High-Cadence Cycling On Overground Running Performance In Recreational Runners, Matthew Ott

Master's Theses

Cycling is a commonly used exercise because it provides a controllable cardiovascular and musculoskeletal demand while imposing relatively low impact on the rider. High-cadence cycling (HCC) has been shown to influence subsequent running performance and gait performance by increasing cadence and reducing work rate when cycling prior to running. However, most of this work has focused on triathletes and older adults. Therefore, the purpose of this study was to examine the acute effects of HCC on subsequent 800 m running performance and spatiotemporal parameters in adult recreational runners. Thirty recreational runners completed two testing sessions. On Day 1, participants performed …

A Reconfigurable Architecture For Dense And Sparse Matrix Multiplication In Processing-In-Memory, Timothy Avila

Theses

Traditional Von-Neumann computing architectures suffer from a fundamental limitation known as the memory wall, where performance is constrained by the cost of data movement between memory and processing units rather than by computational capability. This limitation is particularly pronounced in data-intensive workloads such as machine learning (ML) and hyperdimensional computing (HDC), where matrix-vector operations dominate execution and are often memory-bound. Processing-in-Memory (PIM) architectures have emerged as a promising approach to mitigate this bottleneck by enabling computation to occur within or near memory, thereby reducing data movement overhead. However, due to these processors' specialized nature and the limited integration of general-purpose …

Susceptibility To Memory Errors Created By Leading Questions Based On The Perceived Authority Of Interviewer, Clay K. Wollard

Undergraduate Honors Theses

It has been well established that memory of an event can be modified by introducing misinformation through questioning. This study fills a gap in the research literature by testing the potential relationship between perceived authority and susceptibility to misinformation. This was measured through showing participants a video of a traffic accident and asking them questions about the events they witnessed. Participants were also asked to rate their confidence in the correctness of each answer to determine if there are any correlations between authority, correct answers, misinformation, and confidence. Authority was conveyed through the clothing worn by the researcher during each …

Arrest Rates And Police Presence In East Bay Area Counties Of Northern California, Christiana M. Tyler

Electronic Theses, Projects, and Dissertations

In this research study, we discuss the social phenomenon of mass incarceration in the United States. Previous research has evidenced clear racial disparities within this social issue, but has yet to make a connection between high incarceration rates and the sheer volume of police officers in many communities. This descriptive study sets out to discover whether there is a difference in incarceration rates based on the level of police presence in select counties in Northern California. The study will measure police presence by the number of police officers, using secondary data from U.S. government and nonprofit agencies. The researcher hypothesizes …

One evidence-based intervention that can address this problem and improve medication accuracy and continuity of care is pharmacist-led medication reconciliation at discharge. The proposed project will identify the impact of pharmacist involvement in discharge pharmacy reconciliation on patient outcomes and readmission. The present paper is quantitative, descriptive study, where retrospective and prospective information was used to estimate medication discrepancies, readmission, and patient compliance in adult inpatients. The evidence substantiates pharmacist-led medication reconciliation …

Girlhood, Interrupted: An Intersectional Feminist History Of Decolonizing And Reclaiming Womanhood, Ayden Kelly

Electronic Theses, Projects, and Dissertations

In the past few decades, social and political discourse surrounding womanhood and who is considered a "real" woman has led to the execration of transgender women. This work will explore how recent discourse and rhetoric surrounding who is and who is not a “real woman” can be traced to nineteenth century notions of “true womanhood” that excluded women of color. In the late 19th and early 20th centuries, with westward expansion, settler colonialism, residential schools, slavery, and post-emancipation serving as backdrops, this work will also analyze how ideologies of womanhood have interrupted and suppressed women of color throughout Western American …

Seeing And Doing: Disciple-Making And Moral Formation In The Gospel Of John, Stephen Yeagley

Journal of Adventist Youth and Young Adult Ministries

God’s revelation in Jesus Christ both discloses and obligates, presenting an alternate view of reality to be seen and an ethical command to be done. The Gospel of John weaves the motifs of “seeing” and “doing” into a single disciple-making process. It aims to transform a person’s identity, worldview, and understanding of God before inviting ethical emulation. This sequence evokes a moral response, calling disciples to do “just as” Jesus and His Father have done, particularly in love, unity, mission, and otherworldliness. Moral empowerment occurs relationally through a third motif: “dwelling.” Using the metaphors of home, family, and friendship, John …

Discipling Students On Non-Adventist College And University Campuses, Ronald R. Pickell

Journal of Adventist Youth and Young Adult Ministries

Social science has long demonstrated the importance of faith development in the period of college life. An Adventist faith development process is needed for the spiritual life and faith development of students who attend non-Adventist universities. This paper expands on my previous research on this topic and features the Journey—a series of student Bible study small group experiences. Journey introduces students to the mission and message of Jesus, inviting them to believe in Jesus and follow Him in lifelong discipleship. This small group Bible study series contributes to the discipleship process for students in the unique setting of today’s university …

Discipleship Includes Both Acceptance And Change, Steve Case

Journal of Adventist Youth and Young Adult Ministries

Discipleship—following Jesus—includes both acceptance and change. Acceptance from Christ transforms the orientation of humans to follow the God who initiates and completes our acceptance. But discipleship also involves change—sometimes radical and sometimes gradual. The transformation that began with acceptance continues with change. An emphasis of one over the other, or worse, ignoring or denying one of these two dynamics, results in a skewed discipleship. Both acceptance and change remain supernatural actions in the God-human relationship of discipleship.

Generational Interpretations Of Feminism: A Qualitative Study Of Women’S Perspectives, Molly Sabia Msw

All Student Scholarship

The current study gathered information on how women across five generations interpret feminism. Nine women were interviewed: (2 per generation, except the silent generation was 1). Understanding how women across five generations interpret feminism helps determine whether perspectives of feminism are due to a difference in time period or other variables. Based on research that has been conducted, we know that there are different views and interpretations of feminism on a broad scale; this study dove into participants’ perspectives and generational influence.

The preliminary findings of this study suggest there are some areas of the Feminist Movement that exhibit generational …

Kinesio Tape As A Primary Treatment Tool: An Evidence-To-Practice Review, Connor Kelly

All Student Scholarship

Kinesio Tape (KT) is widely used in athletic training as a non‐invasive intervention for pain, swelling, and functional limitations, yet research findings remain inconsistent.1-3,5,7This Evidence‐to‐Practice Review evaluates current literature, including a systematic review and a meta analysis to determine the clinical effectiveness of KT as a primary treatment modality compared to several established modalities. The review synthesizes foundational theory, historical development, unsubstantiated claims, evidence‐based uses, and comparative effectiveness relative to other therapeutic interventions. Findings from the guiding manuscript indicate that KT may provide small, short‐term improvements in pain and function, but it is rarely superior to established treatments such as …

Bat Tracking Metrics As Potential Predictors Of Oblique Injury In Major League Baseball Hitters, Nicholas Deangelis

All Student Scholarship

Epidemiological data shows an increase in oblique injuries in Major League Baseball (MLB) in recent years. Throughout MLB front offices, more emphasis is being placed on bat speed and hitting the ball hard as indicators of success as a hitter. This study aims to investigate whether higher values in these advanced swing metrics are predictors of oblique injury in MLB hitters. Publicly available injury data was sourced to collect a sample of hitters who suffered oblique injuries during the 2024 and 2025 MLB seasons. These injured hitters were matched with a non-injured counterpart, and a multiple regression model was implemented …

From Words To Growth: Exploring Employee Perceptions Of How Organizational Culture Shapes Effective Feedback Experiences, Amanda Neuts Phd

All Student Scholarship

Organizational culture plays an essential role in shaping how employees experience feedback and whether feedback supports professional growth. While feedback processes have been widely studied, less emphasis has been placed on how employees interpret the organizational culture conditions that influence feedback effectiveness. This qualitative phenomenological study explored employee perceptions of how organizational culture shapes feedback experiences and their impact on professional development, satisfaction, and engagement. Grounded in Schein’s Model of Organizational Culture and supported by Social Exchange Theory, this study investigated how values, underlying assumptions, and artifacts interact with relational dynamics such as trust, reciprocity, and fairness. Analysis of eight …
