Board-Level Operating System Infrastructure In Rust, Lydia Klaus

McKelvey School of Engineering Graduate Student Theses & Dissertations

Memory and multi-threading problems are the cause of many exploits and security vulnerabilities, and errors of this nature are easy to cause in programming languages such as C and C++. Despite this, these languages are still heavily used for systems programming and underpin the majority of operating system kernels. This is partially due to a lack of suitable replacements; however, Rust is becoming more prominent as an option for systems programming. This language features a much more stringent approach to memory and multi-threading safety. It also aims to support a wide range of hardware targets, including microcontrollers, which have long …

Establishing Caenorhabditis Elegans As A Platform For Bioaccumulation And Selectivity Screening Of Anthelmintic Compounds, Jiarui Li

McKelvey School of Engineering Graduate Student Theses & Dissertations

To address the cuticular barrier in anthelmintic discovery, this study establishes a bifurcated framework in Caenorhabditis elegans. First, HPLC-based quantification of 14 PIM inhibitors revealed that cuticular penetrance is primarily dictated by phylogenetic lineage (Clade V) rather than ecological niche. Specifically, C. elegans demonstrated a significant pharmacokinetic correlation with the hookworm Ancylostoma ceylanicum (Clade V) but not the whipworm Trichuris muris (Clade I), validating it as a superior surrogate model for hookworm bioaccumulation. Within this small molecule inhibitor library, SGI-12was identified as a lead candidate with superior potency against C. elegans and bioaccumulation. Second, target validation using a C. …

A Different Starting Point: Youth Discipleship For A New Generation, Rogelio Paquini

Journal of Adventist Youth and Young Adult Ministries

The process of discipling youth in contemporary society significantly diverges from the approaches utilized in previous generations. The current landscape is characterized by unique challenges, diverse worldviews, and complex relationship dynamics, which collectively create an environment that may be unfamiliar to traditional church discipleship efforts. This paper aims to elucidate the most pertinent elements of discipleship concerning youth and young adults. The analysis presented herein is grounded in a review of contemporary literature and empirical data derived from a survey of young adults regarding their experiences and perspectives on discipleship.

Smart Medical Support System And Swin Transformer Framework For Breast Cancer Detection And Segmentation In Mammograms, Ahed Abugabah, Prashant Kumar Shukla, Piyush Kumar Shukla, Abhishek Dwivedi

All Works

Accurate and reliable breast cancer detection from mammographic images remains a critical challenge due to subtle lesion appearance, high intra-class variability, and class imbalance inherent in clinical datasets. To address these issues, this study proposes Swin-BreastNet, an explainable and optimization-driven deep learning framework for binary classification of benign and malignant breast lesions from full-field digital mammograms. The proposed approach leverages the hierarchical Swin Transformer model to effectively capture fine-grained local texture patterns and long-range contextual dependencies through Shifted Window Multi-head Self-Attention (SW-MSA). A key novelty of this work lies in the integration of Harris Hawks Optimization (HHO) for automated hyperparameter …

(A)Typicality Of Inclusivity: A Neuro-Inclusive Tourism Workforce, Rigin Sebastian, Noufal Naheem Kottekkadan, Toney K. Thomas, Paolo Mura

All Works

By focusing on the social reality of neurodiversity, an alternative expression of the human condition to sensory perception and social engagement, this research note advocates a collective responsibility for neurodiversity inclusion in the tourism workforce. Specifically, this work introduces and critically discusses a ‘critical neurodiversity paradigm’ to scrutinise the pathologisation of diversely abled individuals working in the tourism industry. As such, this study contributes a neuro-inclusive framework for future research based on macro, meso and micro approaches alongside propositions for workforce equity initiatives.

Public Health Responsible Ai Capability (Ph-Raic) Framework: A Conceptual Model For Integrating Ai Into Public Health Agencies, Arnob Zahid, Ravishankar Sharma, Rezwan Ahmed

All Works

Background: Artificial intelligence (AI) is transitioning from experimental pilots to core public health functions such as disease surveillance, resource planning, and analysis of social and structural determinants of health. Yet, health data collection and stewardship remain fragmented across the globe; some jurisdictions still rely on paper-based systems, while others operate noninteroperable digital systems that can exacerbate inequities. Treating health data as a global good therefore requires governance that enables innovation while protecting rights, safety, and trust. This study aims to develop a conceptual meso-level capability framework that translates responsible AI principles into organizational practices for public health agencies. Methods: We …

Flicking Fibres: Microfibres Act As Sensory Disruptors In A Marine Crustacean, Ari Drummond, Alexander D.M. Wilson, Lucy M. Turner, Mark Briffa

School of Biological and Marine Sciences

Anthropogenic inputs to the environment—including microplastics and microfibres—are global stressors known to impair multiple facets of organismal biology. However, the effects of these pollutants on sensory structures remain critically understudied. Sensory systems mediate organism-environment interactions, and pollution-derived impairment at these interfaces may cascade through bioprocessing, from information acquisition to behaviour and ultimately fitness. Microfibres, in particular, pose an additional threat, potentially physically obstructing sensory organs and chemically interfering with sensory processes. Using an invertebrate model of sensory biology, Pagurus bernhardus, we tested whether dryer lint—a complex, heterogeneous mix of treated microplastic and cellulose fibres, and other anthropogenic contaminants—acts as a …

Federalism, Fragmentation, And The Limits Of Universal Welfare In The United States: A Comparative Analysis Of Germany And Sweden, Jacqueline Arena

Political Science

This paper examines why the United States welfare state struggles to achieve universal social protection, focusing on the role of federalism, political ideology, and public opinion. It argues that the U.S. welfare state is structurally fragmented due to the division of authority between federal and state governments, which produces uneven, inconsistent, and often inadequate access to social benefits. This fragmentation is rooted in historical developments, including New Deal era political compromises, racialized policy exclusions, and resistance from organized interest groups, which embedded decentralization and inequality into the system’s foundation. Using Gøsta Esping-Andersen’s welfare regime typology and T.H. Marshall’s concept of …

Albany City As A Case Study In Language Mapping, Storm Pupina

Linguistics

This thesis uses Albany, NY, as a case study in urban language mapping, following the example of many other language mapping projects, most notably the NYC Language Mapping Project. Albany's languages and linguistic features were analyzed to better understand the area's linguistic ecology and ongoing heritage-language maintenance efforts. Various types of American Census data were compared to reach the conclusions. Despite not being a major city, Albany is bustling with both new and old language communities. Similar efforts with more varied data-gathering tactics would greatly benefit other American urban landscapes.

Low-Cost Rf Exposure Monitoring With Tinyml Prediction, Sanad Sahawneh

Nanoscale Science & Engineering (discontinued with class year 2014)

The proliferation of wireless technologies has produced a dense, increasingly heterogeneous radio-frequency (RF) environment that surrounds modern life. While regulatory bodies such as the Federal Communications Commission (FCC) and the World Health Organization (WHO) maintain exposure guidelines, the tools that ordinary people, educators, and small institutions can use to actually observe RF exposure in their own spaces remain expensive, specialized, and largely confined to professional laboratories. Spectrum analyzers and calibrated field probes routinely cost between five hundred and one hundred thousand dollars per unit, placing continuous local monitoring out of reach for most environments where exposure questions are most natural …

Hdra-Fusion: Hybrid Detection With Routed Architecture For Manipulation-Aware Ai Face Forgery Detection, Omar Ebeid

Theses and Dissertations

With the rapid advancements in artificial intelligence-based image generation and manipulation tools, it is extremely difficult to detect if an image is genuine or artificially crafted. Despite extensive research in this area, existing image detection systems suffer from three major problems: suboptimal cross-dataset generalization due to shortcut learning of dataset-specific patterns, unreliable probability estimates due to domain shift, particularly in cross-manipulation evaluation settings, and an inability to detect images manipulated by multiple types of manipulations within a single detection framework. To address these limitations, we propose HDRA-Fusion (Hybrid Detection with Routed Architecture), a framework built on the conclusion that different …

Design And Simulation Of Anti-Resonant Hollow-Core Fiber For Sensing Applications, Pravallika Kante

Theses and Dissertations

This thesis presents the design and simulation of an 8-tube single-ring anti-resonant hollow-core fiber for sensing applications, with particular emphasis on methane gas detection at the fundamental absorption wavelength of 3.3 µm. Conventional solid-core silica optical fibers exhibit strong multi-phonon material absorption beyond 2.5 µm, rendering them fundamentally unsuitable for efficient light guidance and direct gas sensing at mid-infrared wavelengths. Anti-resonant hollow-core fibers overcome this limitation by guiding light predominantly through an air-filled hollow core via the anti-resonant reflecting optical waveguide mechanism, in which the thin silica glass walls of the cladding tubes act as Fabry-Pérot etalons that confine the …

Host Families’ Perspectives Of The Impact Of The Commodification Of Education On The Student-Host Family Relationship In Study Abroad, Guadalupe Bustamante

Dissertations

The growing commodification of education has reshaped study abroad in ways that extend beyond marketing and program design. While homestays have traditionally been viewed as the ideal format for cultural immersion and language acquisition, research has largely overlooked how these trends affect the student-host family relationship from the family's perspective.

This study examines whether, and, if so, how Spanish host families perceive their roles and relationships with the American students they host have been impacted by these trends. Using a qualitative exploratory case study design, the research focused on representatives from eight families in Madrid, who have hosted U.S. students …

Examining The Relationship Between Active And Passive Screen Media Design, Engagement, And User Motivation And Impacts On Mental Health In Emerging Adults, Susan Richey

Human Development and Family Sciences Undergraduate Honors Theses

Rates of depression among adolescents and emerging adults have increased in recent years, with screen media use identified as a potential contributing factor. Prior research links passive screen use to poorer mental health outcomes, while active engagement shows mixed effects; however, many studies overlook differences between platform design and actual user behavior, as well as the role of notifications. This study examined how screen media habits, platform design, user motivations, and notification settings relate to mental health among emerging adults. A sample of 399 participants (ages 18–29) from a large southeastern U.S. university completed a survey assessing screen use, engagement …

Perceived Campus Safety And Psychological Flexibility As Moderators Of Posttraumatic Stress And Anxiety Following Indirect Exposure To School Gun Violence, Samara Trout

Honors Theses

The growing prevalence of gun violence in school settings within the United States, combined with extensive media coverage of these events, has heightened concerns regarding the psychological impact of indirect trauma exposure among students. The present study examined associations between indirect exposure to gun-based school violence and symptoms of posttraumatic stress and anxiety among undergraduate students at Western Michigan University (WMU). A secondary aim was to explore whether perceived safety and psychological flexibility/inflexibility moderated associations between indirect exposure and psychological distress. Using a cross-sectional correlational design, undergraduate students (N = 33) completed a self-report survey containing screening assessments, attention …

Consumer Willingness To Pay- Mauritius, Addison Guess

Finance Undergraduate Honors Theses

For my thesis, I will be diving into my personal and professional learnings from my summer internship abroad. My group completed a research project in Mauritius, an island off Africa. This island gained independence less than a century ago, and since then, has gone from a low-income farming country to a developing middle-income country with a heavy reliance on rice. Our task was to survey people to determine consumer willingness to pay regarding low glycemic rice. This took place in Mauritius because of the high diabetic rate in this area. Similar to many Asian countries there is a high diabetic …

Timing Of Parental Divorce And Spiritual Behavior In Young Adulthood: A Quantitative Study, Marcus A. North

Phase Equilibria Modeling Constraints On Seismic Velocity And Density For Mafic Granulites In The Athabasca Granulite Terrane, Western Canadian Shield, Olivia Wyllie

Geosciences Undergraduate Honors Theses

Samples of mafic granulite and eclogite from the Athabasca granulite terrane, thought to be representative of the lower continental crust, were analyzed via bulk geochemistry analysis and seismically modelled with Perple_X v.7.1.6. Modeled P-wave speeds, S-wave speeds, and densities for the samples were graphed by region and calculated for wet (1.00 wt.% H2O) versus dry (0.01 wt.% H2O) conditions at 460 °C and 648 °C. The samples were found to have higher median P-wave values than those determined by Rudnick and Fountain (1995; 7.4 km/s to 7.8 km/s, as compared to 6.9 km/s to 7.2 km/s). This indicates both a …

Martha Mitchell: Loud Mouth Of The South, Emma Bernice Kolker

History Undergraduate Honors Theses

In this paper, I will argue how Martha‘s Arkansas identity presents itself as a double edge sword, with her personality attracting the attention of the public with the consent of powerful men in the Republican party, while at the same time her comments and actions were the very reason she was blamed and marginalized by the same men who allowed her to speak in the first place.

A "Felon" In The White House: A Study Of The 2024 Election And The Racialized Violence Of The Word "Felon" In American Politics, Val Arnold

FCRH Honors Program Theses

One of the campaign strategies pursued by the Democratic Party in the 2024 presidential election was the use of a felon-centered discourse when discussing Donald Trump. Through the use of such discursive strategies, the Democratic Party attempted to evoke the sense of fear typically associated with discussions of crime, hoping to make voters associate the “fear” with Trump, a white man. In the media, the language used in speeches and advertising campaigns serves as a powerful tool. The current literature discusses how language operates as a “representational system,” and ultimately, words serve to give meaning. Although many articles separately discuss …

Subzero: Original Music For Piano And Live Electronics, Frank Newton

Honors College Theses

Subzero is a set of three compositions for piano and live electronics inspired by themes of nature and human perception. The term “live electronics” in a musical context refers to the use of technology to generate or trigger sounds in real time during a performance. These pieces were written specifically for use with a computer music program I designed using Max/MSP to respond to and accompany the performer. Subzero combines acoustic and synthesized sounds to examine three subjects of the natural world and how we, as humans, react to them. The compositional process of the set was informed in part …

Gaining Mussel: Evaluating Reintroduction Success Of Native Freshwater Mussels In Nebraska And Eastern Wyoming, Travis A. Moore

School of Natural Resources: Dissertations, Theses, and Student Research

Freshwater mussels are one of the most imperiled groups of organisms in North America, with over two-thirds of species considered threatened, endangered, or of special concern. These long-lived bivalves are essential to stream ecosystems, acting as filter feeders that improve water quality and as indicators of aquatic health. In Nebraska and Wyoming, native mussel populations have declined sharply due to habitat modification, pollution, and reduced connectivity. Two species of particular concern are the Plain Pocketbook Lampsilis cardium, listed as Tier I at-risk in Nebraska, and the Fatmucket Lampsilis siliquoidea, a Tier II at-risk species. In response, state agencies …

The Impact Of Glucose Exposure On Organic Cation Transporters (Oct) Function In A Corneal Epithelial Cell Line, David A. Garza

Theses & Dissertations

Organic cation transporters (OCT) facilitate the movement of neurochemicals and medications, contribute to the removal of cellular waste, and facilitate neuronal communication. Three subtypes of these high-capacity, low-affinity transporters (OCT1, OCT2, and OCT3) are differently expressed in peripheral tissues such as the liver, kidneys, as well as the central nervous system. OCTs are also expressed in ocular tissues. Chronic hyperglycemia is a complication commonly associated with diabetes that can lead to ocular diseases such as diabetic keratopathy, which affects the cornea. In this project, we expose immortalized human corneal epithelial cells (HCE-S) to various glucose concentrations to study their impact …

Moderating Effects Of Defense Mechanisms On The Link Between Dark Triad Traits And Stress: A Replication With Addition Of Early Trauma, Ngayin Cheng

Student Theses

Literature suggested Dark Triad traits, comprised of narcissism, Machiavellianism, and psychopathy, are linked to adverse childhood environment and maladaptive coping that contribute to negative mental health outcomes, but Richardson and Boag's study (Richardson & Boag, 2016) was one of the few studies that first found Dark Triad traits are associated with immature defenses and higher perceived stress simultaneously. This replicated study aims to verify the original findings of their research by examining how defense mechanisms moderate the relationship between Dark Triad traits and perceived stress. A sample of 199 participants completed self-report measures assessing the Dark Triad traits, defense styles, …

A Phenomenological Study: Examining Organizational Change Initiatives Within The U.S. Army To Influence Racial Climate, Reginald Gerald Dash Ii

Electronic Theses and Dissertations

This research study was aimed at examining organizational change initiatives influencing the racial climate among African American soldiers in the United States (U.S.) Army. African Americans comprise a significant portion of the U.S. Army. However, African Americans’ significant contributions do not readily translate into “equal treatment”, which includes proportional representation at the highest levels of leadership. African Americans in the U.S. Army face career navigation challenges rooted in systemic racial division. The goal of this qualitative phenomenological study was to add African American soldiers’ voices to the existing literature by interviewing African American soldiers with at least five years of …
