The Subadults Of Casas Grandes: A Bioarchaeological Study, Holli Kaye Mcdonald

Graduate Student Theses, Dissertations, & Professional Papers

Across the span of nearly eight hundred years, from AD 700-1450, the societies of the Casas Grandes region waxed and waned and left an astounding representation in the archaeological record. Best-known through the temporally older site of Convento (occupied during what is known as the Viejo Period) and the later site of Paquimé (occupied during the Medio Period), gradual cultural expansion and florescence across this period are witnessed through a variety of findings across decades of anthropological investigation.

Along with the artifacts and architecture unveiled during initial excavations at Paquimé and Convento, remains of 654 individuals were catalogued as well. …

The Forensic Implications Of Hydrochloric Acid (Hcl) Exposure On Dna Preservation In Human Teeth, Shaelyn Lee Zimmerman

Graduate Student Theses, Dissertations, & Professional Papers

Identity is a human right, and forensic anthropological methods are often aimed at returning identity to decedents. Three main pathways are used for the identification of human remains: fingerprints, dental records, and DNA analysis. Identification efforts may be hindered when perpetrators attempt to obscure the victim’s identity. In cases where corrosive substances, such as hydrochloric acid (HCl) are used, dental comparison and fingerprinting often fail and genetic analysis becomes the best chance of achieving personal identification.

Previous studies have shown teeth are an excellent source of DNA. Large, multi-rooted teeth, such as molars, are often preferred because they contain the …

ASEAN Journal on Science and Technology for Development

Background: Timely availability of vaccine packaging is critical to pharmaceutical supply chain reliability, as packaging materials play a key role in maintaining cold chain integrity during distribution. Inadequate availability of packaging materials can disrupt vaccine delivery even when finished vaccines are ready for shipment. The case company faces frequent delivery delays, insufficient safety stock, and irregular replenishment of vaccine packaging materials, which have jeopardized the organization’s target of achieving a 90% on-time delivery rate.

Objective: To design and evaluate an Economic Order Quantity (EOQ)–based inventory dashboard for vaccine packaging that standardizes ordering decisions and strengthens stock visibility in pharmaceutical distribution …

Impact Of Childhood Trauma On Perceptions Of Health: Examining The Role Of Religiosity As A Protective Factor Among Black And African American Adults, Patrice Penrose

West Chester University Graduate Theses, Dissertations, and Final Projects

Purpose: Childhood trauma has detrimental immediate and lifelong impacts on health. Black and African Americans experience higher rates of potentially traumatic events (PTEs) than the general population. Religiosity, a common coping mechanism for many who experience trauma, could serve to moderate the impacts. This study examines whether the importance of religion buffers against the impact of childhood exposure to PTEs on adult perceptions of health and assesses whether social support and/or coping mediate the relationship between religiosity and perceived health.

Method: This study analyzed data from 2,537 Black and African American participants in the National Longitudinal Study of Adolescent to …

Reframing Sexual Assault And Intimate Partner Violence Through A Maternal And Child Health Lens: Implications For Integrated Prevention, Policy, And Practice, Daija C. Gibson

Theses and Dissertations

Sexual assault and intimate partner violence remain persistent public health concerns in the United States, with significant consequences for individual health, family stability, and population well-being. Although these forms of violence are frequently addressed through criminal justice and behavioral health frameworks, less attention has been given to their implications within maternal and child health, where relational dynamics, life course development, and intergenerational outcomes are central. This study reframed SA and IPV as core MCH issues to examine how integrated, systems-based approaches can strengthen prevention efforts. A structured literature review and systematic synthesis of peer-reviewed studies published between 2015 and 2026 …

Understanding Maternal Morbidity And Mortality Rates In Georgia, Ebony Hall

Theses and Dissertations

The United States continues to have a significant concern for public health regarding the maternal morbidity and mortality rates. In contrast, women of African American descent and other marginalized populations maintain a disproportionately higher rate of pregnancy-related disparities. More specifically, in Georgia, a persistent number of disparities can correlate to a lack of access to adequate prenatal care, insurance status, and many other social determinants of health that are linked to the contribution of adverse maternal health care outcomes. The purpose of this research study is to evaluate various maternal health experiences during pregnancy, while focusing on the occurrence of …

Child Maltreatment Risk Identification In Complex Caregiving Environments: A Public Health Review Of Split-Custody And Multi-Household Family Contexts, Makenzie Lee

Theses and Dissertations

Child maltreatment remains a significant public health concern with lifelong consequences for children's health, development, and well-being. As children's caregiving environments become increasingly diverse through split-custody arrangements, blended families, kinship care, and other multi-household contexts, recognizing and assessing child safety concerns may become more complex. Although these family structures are not inherently associated with maltreatment, the distribution of caregiving responsibilities and information across multiple households may complicate child maltreatment risk identification.

This capstone presents a scoping review of peer-reviewed literature examining child maltreatment risk identification within complex caregiving environments. The review synthesized evidence related to caregiving environments, caregiver relationships, child …

Caring For Your Heart During Survivorship After Pediatric Cancer: A Visual Education Guide On Chemotherapy-Induced Cardiotoxicity, Bryona Rose Hamilton

Theses

Chemotherapy is an effective weapon in the fight against pediatric cancer. However efficient, treatment can lead to side effects that last long after a patient finishes their last round of chemotherapy. This thesis examines current research on chemotherapy-induced cardiotoxicity, a side effect of chemotherapy treatment caused by a class of chemotherapy drugs called Anthracyclines (such as doxorubicin and daunorubicin). While effective chemotherapy agents, these drugs have been known to cause late long-term heart damage when used to treat pediatric cancers such as Acute Lymphoblastic Leukemia (ALL), Acute Myeloid Leukemia (AML) and Pediatric Sarcoma. A written portion of this thesis project …

A Novel Nephron: 3d Visualization Of Glomerular Filtration In The Kidney, Cassie Young

Theses

Renal physiology, particularly the process of glomerular filtration, remains one of the most conceptually challenging topics in medical education due to its microscopic scale, dynamic pressure relationships, and structural complexity. Understanding how plasma passes through the glomerular filtration barrier requires spatial reasoning across multiple levels—from the gross anatomy of the kidney to the ultrastructure of capillaries, podocytes, and the glomerular basement membrane. This thesis addresses these challenges through the development of a scientifically accurate three-dimensional (3D) animation that illustrates glomerular filtration within its anatomical and physiological context. Designed as a visual teaching aid, the animation aims to improve comprehension of …

Dna Landscape Tool: An Interactive Webpage, Kerstyn Gay

Theses

Deoxyribonucleic acid (DNA) is a molecule that carries genetic information that makes up every organism. DNA is typically introduced into the biology curriculum starting in high school and depending on an individual's educational path can continue through college. Although taught frequently during school, elements of DNA can be difficult for students to grasp, due to the different visual representations of DNA found in various resources. For instance, when comparing an illustration of a chemically accurate nucleotide base to an abstract visualization of a chromosome learners often aren’t given enough scaffolding to see how one representation relates to the other, which …

Impact Of Water Quality And Gear Type On Eastern Oyster (Crassostrea Virginica) Growth In Narragansett Bay, Ri, Jacqueline Rosa

Open Access Master's Theses

Oyster aquaculture is expanding in Rhode Island, yet key farming regions in the lower West Passage of Narragansett Bay (WPNB) lack the in-situ, high-temporal resolution monitoring needed to evaluate emerging stressors and support production. At the same time, the industry is undergoing rapid technological development aimed at improving production while reducing labor and overall costs. In recent years, a low-maintenance, alternative surface gear was introduced in WPNB; however, its impact on oyster performance relative to traditional cultivation methods has not been quantified. This study established a 1.5-year continuous water quality time series in WPNB and paired these observations with …

Enhancing Bay Scallop Monitoring Using Machine Learning And Semantic Segmentation With Benthic Visual Imagery, Waheed Odubayo

Open Access Master's Theses

Effective monitoring of benthic ecosystems requires scalable approaches capable of simultaneously identifying key species and quantifying habitat composition. In Narragansett Bay Rhode Island, bay scallops, Argopecten irradians, serve as important ecological indicators, yet traditional survey methods remain labor-intensive and spatially limited. This study presents an automated deep learning framework for scallop detection and habitat segmentation using underwater benthic imagery.

The proposed system combines three components: (1) YOLO based object detection for identifying live scallops, (2) U-Net semantic segmentation for quantifying benthic habitat classes (eelgrass and sand/silt), and (3) a geospatial contrastive learning framework (GeoCLR) to leverage spatial continuity in …

Investigating Netarts Bay, Oregon Coastal Landscape Change From Tectonic Subsidence Through Isotopic, Stratigraphic Records And Quantifying Dune Influence On Salt Marsh Morphodynamics, Emily Hall

Open Access Master's Theses

Coastal salt marshes on tectonically active margins face dual pressures from episodic seismic events and anthropogenic modifications. This study investigated how the 1700 CE Cascadia Subduction Zone earthquake and the 1900 CE introduction of invasive dune grass influenced back-barrier salt marsh morphodynamics at Netarts Bay, Oregon. It was hypothesized that (1) salt marsh habitats and elevation transitions would be detectable in geochemical proxies preserved in stratigraphy, (2) modern dune stabilization significantly limits mineral sediment delivery to the salt marsh, and (3) this reduction would be preserved in the stratigraphic record. Stratigraphic and isotopic analyses of sediment cores incorporating CT scans, …

Using A Novel Approach To Measure Phonological Working Memory In Parents Of Children With Autism: A Nonword Repetition Study, Giavanna Galati

Open Access Master's Theses

Background: The etiology of Autism Spectrum Disorder (ASD) has been a topic of debate among researchers for many years. Fundamental evidence, especially from twin studies, supports a strong genetic component. This evidence now prompts us to examine first-degree relatives of individuals with ASD. Many first-degree relatives, especially siblings and parents, often exhibit subclinical traits of autism, referred to as the Broad Autism Phenotype (BAP). Several researchers have investigated personality traits and pragmatic language skills; however, few researchers have investigated core language skills, particularly phonological working memory (PWM), in parents of children with ASD (pASD). Purpose: Past research has …

This model is used …

Dynamics Of Single-Walled Carbon Nanotubes In Structured Complex Fluids, Sepehr Yari

Open Access Master's Theses

Cancer survival depends strongly on the stage at which the disease is detected, motivating the development of biosensors capable of identifying early changes in cellular state. Single-walled carbon nanotubes (SWCNTs) are promising intracellular biosensors because their intrinsic near-infrared fluorescence, photostability, and tunable surface chemistry and lenght enable prolonged measurements in living cells. Disease such as cancer can progress and alter intracellular physical properties, suggesting that SWCNT motion may provide a physical readout of changes in cellular state. Interpreting this motion is challenging, however, because the cytoplasm is structurally heterogeneous and contains both passive fluctuations and active transport processes. As a …

Health Truth To Power: Professional Collaboration To Bolster Trust Against Misinformation, William M. Sage, Keegan D. Warren

Faculty Scholarship

This Article is about health, leaving aside more general challenges to shared civic information today. The Article begins by surveying the principal challenges for health information in post-pandemic, arguably post-truth America, and then describes briefly the sources and limits of medical professional authority. Noting the double-edged sword of free speech guarantees under the U.S. Constitution, the Article continues by commenting on speaking truth to government, to industry, and to the crowd. Next, the Article considers the physicians’ role in speaking truth to power from the perspective of standard medical professional ethics and identity, comparing it to that of lawyers. Finally, …

Using Network Models To Understand Biological Signaling Architecture, Russ White, Emily Brown Reeves, Gerald L. Fudge

Faculty Publications

Engineers have developed abstract network models to better understand the recurring problems faced by communication systems. This paper argues that these models can be generalized to describe biological communications systems given that they share many requirements with human-designed systems, including functional requirements and physical constraints. Leveraging collaboration, biologists and engineers can work together to use well-understood communication systems, designed to carry data across a computer network, as a model for analyzing less well-understood biological communication systems in order to make predictions and uncover previously unknown functionalities. To illustrate this approach, we apply the Recursive Internet Network Architecture model (RINA) to …

Trigonometric Continuous-Variable Gates And Hybrid Quantum Simulations Of The Sine-Gordon Model, Tommaso Rainaldi, Victor Ale, Matt Grau, Dmitri Kharzeev, Enrique Rico, Felix Ringer, Pubasha Shome, George Siopsis

Physics Faculty Publications

Hybrid qubit-qumode quantum computing platforms provide a natural setting for simulating interacting bosonic quantum field theories. However, existing continuous-variable gate constructions rely predominantly on polynomial functions of canonical quadratures. In this work, we introduce a complementary universality paradigm based on trigonometric continuous-variable gates, which enable a Fourier-like representation of bosonic operators and are particularly well suited for periodic and non-perturbative interactions. We present an ancilla-based framework for implementing trigonometric gates with arguments given by arbitrary Hermitian functions of qumode quadratures. The protocol yields unitary gates deterministically, and non-unitary gates through probabilistic post-selection. As a concrete application, we develop a hybrid …

Memory Effects In Many-Body Systems, Jeffrey Beckstrand

Master's Projects

This thesis investigates memory effects in many-body systems through the MoriZwanzig Formalism for projected dynamics of a Hamiltonian System which yields the Generalized Langevin Equation (GLE). The GLE is a stochastic differential equation (SDE) that studies the dynamics of observables under the effects of many other observables in the system. Although satisfying, the GLE has a term called the Memory Kernel that encodes the past of the system and introduces a computational challenge by introducing a non-Markovian property to the equation. The kernel is often approximated by introducing a delta function, which simplifies the computation, but at the loss of …

Modeling Sealed Deck Construction In Collectible Card Games Using Learning-To-Rank Approach, Michael Dinh Nguyen

Master's Projects

Artificial intelligence has demonstrated strong performance in complex decision-making domains such as chess and Go, motivating research into its application for games with even richer rules and combinatorial complexity. In collectible card games like Magic: The Gathering, deck construction from a constrained card pool is a critical and challenging task that requires evaluating card strength, synergy, and resource balance. This project explores whether machine learning, specifically learning-to-rank (LTR), can effectively model these human decision processes to construct competitive decks in a sealed format. The results found here can also be applicable to other areas of note, such as sports drafting …

Exploring Parents’ Perspective Of Outdoor Occupational Therapy Sessions, Harold Ho, Michelle Huynh, Christina Le, Amy Morrison

Master's Projects

Introduction: Outdoor play is recognized as critical for supporting children’s development across physical, cognitive, and social-emotional domains (Firby & Raine, 2022; Walker & Ray, 2024; Zhu et al., 2024). The current literature suggests that outdoor play strengthens executive functioning, early learning skills, and enhances social-emotional competency (Dinkel et al., 2019; Walker & Ray, 2024; Zhu et al., 2024). Furthermore, accessibility to outdoor play is shaped by contextual factors, including parental perceptions of safety, environmental barriers, and broader societal influences (Cox et al., 2025; Faulkner et al., 2025; Jelleyman et al., 2019). The research suggests that common parental concerns have emerged …

Searching For Cause Of Unexplained Protein Interaction With Multiple Assembly Methods, Gavin Anderson

Master's Projects

Research into colistin adjuvants has identified interactions between a host of proteins and proteins found within certain strains of bacteria. BLAST, a widely adopted local sequence alignment tool, was used to create a database containing the genomes of relevant bacterial strains, which would then be used to query against the previously identified proteins. Many of these strains do not have publicly available assemblies, which makes database construction difficult. CATwalk, a new naïve fragment extender, is first described in this paper and used to extend fragments of interest. BLAST results first identified short fragments with sufficient similarity, which can then be …

Detection And Characterization Of Cancer Using Cfdna Fragmentomic Analysis, Guneet Bhogal

Master's Projects

Cell-free DNA (cfDNA) fragmentomics has emerged as a promising non-invasive approach for detecting and characterizing cancer by analyzing DNA fragmentation patterns. These fragment patterns are unique and can be used to distinguish between tumor and healthy DNA. This paper uses machine learning models to detect cancer by evaluating Shannon entropy of fragment lengths at the first coding exon 1 regions and correlating them to targeted cancer genes. This approach was applied to two datasets consisting of samples with prostate, breast, and lung cancers. Our results indicated that exon 1 fragmentation entropy captures biologically relevant differences in cancer-specific chromatin organization and …

Combining Crispr And Nanoasv To Uncover The Rare Bacterial Communities Of The Human Oral Microbiome, Gilma Ruth Sevilla Alvarez

Master's Projects

Studying the oral microbiome is vital because its health implications are not contained to the mouth. Cariogenic bacteria cause tooth demineralization and oral microbes that translocate to extra-oral organ systems are linked to conditions like Alzheimer’s disease, heart disease, diabetes, and cancer. Some of these pathogens belong to the most abundant phyla in the oral cavity: Bacillota, Pseudomonadota, Bacteroidota, Actinomycetota, Spirochaetota, and Fusobacteriota, which together comprise 94% of the oral microbiome. This project uses CRISPR-Cas9 to deplete sequences from highly abundant phyla and the Eubacteria domain, enriching the remaining 6% of rarer taxa. Paired with NanoASV for single-nucleotide resolution, this …
