Honeybee Colony Response To Probiotic Supplementation And Grazing Practices, Katya M. Busenitz

Department of Entomology: Dissertations, Theses, and Student Research

Honeybee health is a complicated issue. Studies were conducted to scale honeybee (Apis mellifera) health from the microbiome to the landscape. Colony health parameters were measured in response to probiotic administration. Colony capped brood production, colony summer weight gain, and Varroa mite incidence were measured. I found that applications of over-the-counter probiotics did not improve the measured parameters of honeybee health compared to a control group. Results suggest that probiotic application was not beneficial but positive benefits may depend on application method, brand, or strain of probiotics used. I also examined how colony health metrics responded to different …

A Meta-Analysis On Joinder Effects: Do They All Have The Same Magnitude?, Amelia M. Tisk

Student Theses

The present meta-analysis examined whether different forms of joinder and procedural consolidation produce varying levels of prejudice in adjudicative decision-making. Although joinder procedures improve judicial efficiency, psychological research has suggested that combining charges, defendants, or plaintiffs within a single proceeding may increase conviction likelihood, liability judgments, and broader perceptions of wrongdoing. A random-effects meta-analysis was conducted across 22 independent study effects examining charge joinder, defendant consolidation, plaintiff consolidation, multiple-complainant procedures, and related aggregation paradigms. Effect sizes were converted to Pearson’s r whenever possible. Overall, procedural aggregation produced a moderate effect on adjudicative outcomes, r = .27, 95% CI [.22, .32]. …

Chemical Variability In The Unregulated Opioid Supply In The South Bronx, Yeireline Rodriguez

Student Theses

The unregulated drug supply in the United States has become increasingly unpredictable, contributing to persistently high overdose mortality, particularly in structurally marginalized communities such as the South Bronx. While drug adulteration has long been present in illicit markets, the number and pharmacological diversity of adulterants remained limited for much of the twentieth century. Over the past decade, however, the drug supply has undergone a significant transformation marked by the proliferation of potent synthetic opioids such as fentanyl and its analogues, frequently combined with novel sedatives and chemically diverse adulterants. These shifts have introduced increasing chemical complexity into the street drug …

Charting The Course: The Influence Of Mentorship On Women's Careers In Outdoor Education, Jessica M. Callahan

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

Mentorship is a significant contributor to women’s experiences working in outdoor education, yet it remains underresearched in a formal capacity. This study aims to answer the central research question of “What meanings do women give to mentorship experiences in relation to their career development, retention, and professional identity?” A qualitative, phenomenological approach was chosen to be most appropriate, and both synchronous interviews and an online survey were used to collect data. In total, data was collected from 24 participants, which was analyzed using thematic analysis. Identified themes were categorized by the topics of mentor qualities and impact on self, mentorship …

Spatiotemporal Variability Of Differential Reflectivity (Zdr) Columns Due To Environment In Tornadic And Nontornadic Supercells, Adrianne J. Engel

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Polarimetric signatures have been of interest to researchers and operational forecasters since the completion of the WSR-88D network upgrade in 2013. Differential reflectivity (Z_DR) columns, which are collocated with supercell updrafts, are the focus of this study. Microphysical distributions within these signatures can be used to infer updraft strength and elucidate the processes responsible for updraft intensity and evolution. Z_DR column depth, areal extent, and variability of these metrics through space and time are assessed in a dataset of 114 nontornadic and tornadic supercells. Means of column metrics in nontornadic, non-tornado-producing, and tornado-producing analysis times are evaluated …

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 …

Educational Placemaking: The Radical Power Of Play, Hillary René Spencer

Electronic Theses and Dissertations

Too often, play is dismissed as a simple childhood pastime, but what if it were understood as a radical tool for transformation? This research examines how play-based learning (PBL) interventions can serve as a framework for systemic change. Grounded in Edward Soja’s theory of spatial justice, which holds that socially valued resources and opportunities are unevenly distributed across geographic spaces (Soja, 2010), the study investigates how public spaces can serve as culturally reflective sites of learning and, when co-created with children and their communities, help address historical structural inequities. This research establishes educational placemaking as a framework for understanding play-based, …

The study employed a hermeneutical phenomenological design, sampling six Black graduates that participated in improvisational courses as part of the secondary curriculum. Data collection included a demographic questionnaire, semi-structured interviews, and participant journals. The findings of a thematic analysis indicate that improvisation developed …

Listening To Those Who Stay: Support Systems Influencing Special Education Teacher Retention, Carol Jean Dawson

Electronic Theses and Dissertations

Retention among special education teachers is a constant challenge across the country. Educators in these positions often have heavy workloads, emotionally demanding responsibilities, and complex caseloads leading to burnout and high turnover rates. Despite these challenges, most of them persevere in the field for extended periods, which indicate that robust and effective support systems are essential to aiding their commitment. In examining this phenomenon, this qualitative study focused on the lived experiences of six special education teachers who worked in the same school setting for a minimum of five years with the aim of identifying support structures that affect motivation, …

The Impact Of Career And Technical Education Teacher Certification Preparation Programs On Student Industry-Based Certification Examinations, Kaneesha Chameka Celestin

Electronic Theses and Dissertations

Career and Technical Education (CTE) programs are designed to prepare students for high-wage, high-demand industry jobs. However, there is limited research on Career and Technical Education teacher preparation programs (traditional, alternative, and industry-based) and the impact on student outcomes on industry-based examinations, such as ACT WorkKeys. This quantitative study analyzed Career and Technical Education (CTE) teacher preparation programs (traditional, alternative, and industry-based) and 12th -grade students’ outcomes on the 2023-2024 ACT WorkKeys examination and whether relationships exist between the two. Additionally, the research examined each Career and Technical Education teacher certification preparation program individually to determine the differences among traditional, …

A Phenomenological Study: The Cultural Identity Of Black Transfer Students In Higher Education, Briana Lashon Levi

Electronic Theses and Dissertations

This qualitative phenomenological study explored the lived experiences of Black transfer students from the California Community College system to Southern Historically Black Colleges and Universities (HBCUs). Guided by two theoretical frameworks, Afrocentric Pedagogy and Black Identity Development Theory (BIDT), the study investigated how participants described and interpreted their cultural identity as they transitioned from a community college to a Southern HBCU. In this study, cultural identity was understood as a holistic construct that included students’ sense of belonging and their experiences of cultural affirmation, which functioned as core components rather than separate constructs from cultural identity. This research specifically focused …

Why Do Teachers Leave? Investigating Teacher Attrition In A New Orleans Charter School: A Qualitative Phenomenological Case Study, Carlos J. Machuca Rivera

Electronic Theses and Dissertations

The purpose of this phenomenological case study was to investigate the lived experiences of former teachers who worked at Goodlife Academy (GLA), a charter school in New Orleans, Louisiana, between 2019 and 2025, with particular attention to how teachers experienced job satisfaction and job dissatisfaction and how those experiences influenced their decisions to leave Teacher attrition—defined as educators leaving their school or the profession—has been associated with factors such as burnout, inadequate support, low compensation, and persistent challenges in addressing achievement gaps. Although these factors are well documented in the literature, many existing studies rely on quantitative methods and focus …

Beyond The Switch: Identifying Gli2-Associated Secretory Targets For Igm Regulation In Waldenström’S Macroglobulinemia, Trevor Charles Chapman

Master's Theses and Capstones

Waldenström’s Macroglobulinemia (WM) is a rare non-Hodgkin lymphoma characterized by the increased presence of monoclonal IgM circulating in the blood and the infiltration of lymphoplasmacytic cells into the bone marrow. WM cells are heterogeneous, sharing features of both B-lymphocytes and plasma cells while not being able to terminally differentiate. Our labs’ previous work established that inhibiting and knocking down the GLI2 transcription factor effectively reduces IgM secretion in three different WM cell lines. This observed phenotype was discovered to operate through IL-6Rα signaling but whether IgM was regulated transcriptionally was not assessed. GLI2 was initially hypothesized to regulate IgM production …

Shared And Unique Neural Correlates Of Sign And Spoken Language Production: An Ale Meta-Analysis, Grace Robertson

Master's Theses and Capstones

This coordinate-based meta-analysis aimed to identify brain areas that are uniquely active in sign language production during single word/sign production tasks using Activation Likelihood Estimation (ALE). Evidence from a pooled ALE of all studies revealed a shared network between sign and spoken language for language, specifically lexical, syntactic, and semantic selection and retrieval, motor planning and execution, sensorimotor integration, phonological working memory, and visual and multimodal processing. The ALE subtraction (sign language > spoken language) did not reveal any significant clusters above the corrected threshold. However, visual inspection of an uncorrected map revealed that regions responsible for language, spatial attention and …

Advancing Bathymetric Lidar Nearshore Mapping With Self-Supervised Learning, Joseph Wilder

Master's Theses and Capstones

The application of AI/ML to shallow bathymetric mapping with airborne lidar remains limited by a lack of high-quality labeled datasets, extreme spatial variability, and noise introduced by environmental conditions and hardware limitations. These issues reduce the generalizability of traditional statistical approaches for extracting bathymetric points from lidar point clouds, with additional challenges for supervised neural networks arising due to the amount and quality of labeled data required to properly capture broad seafloor characteristics. Recent advances in point cloud machine learning methods have the potential to improve conventional bathymetric processing workflows. This work examines modern self-supervised learning (SSL) methods for bathymetric …

Is Bruen The New Usery?, Tonja Jacobi, Cory Conley

William & Mary Law Review

In 2022, in New York State Rifle & Pistol Ass’n v. Bruen, the Supreme Court revolutionized the Second Amendment, achieving the long-held conservative goal of limiting gun restrictions by imposing an expansive, originalist view of the right to bear arms. However, within just three years, Bruen is showing cracks. Lower court judges are struggling mightily to apply it and are expressing their frustrations in exceptionally frank ways. And already the Supreme Court, in Rahimi v. United States, was forced to reconsider its approach. The Court has been here before, when it tried to revitalize the Tenth Amendment in …

Digital Deterrence Through Financial Controls: Anti-Money Laundering Laws, Lawfare, And The Prc Cyber Threat, Owen T. Tremblay

William & Mary Law Review

[...] Part I provides an overview of the PRC’s cyber force structure and the national objectives it seeks to achieve through state-sponsored cyber operations. Part II examines the existing legal mechanisms employed to combat PRC MCA [Malicious Cyber Activity], including criminal charges, sanctions, export controls, investment restrictions, civil lawsuits, and other regulatory measures. Part III introduces AML laws as an additional tool in the legal and regulatory toolkit used …

Unconstitutional Cruelty, Michael R. Ulrich

William & Mary Law Review

Despite the long history of transgender people and transgender care, state legislatures suddenly rushed to pass a wave of bans on gender-affirming medical care for trans youth over a three-year period beginning in 2021—an alarming surge within a flurry of legal attacks on the transgender community. In analyzing the constitutionality of these bans, courts and scholars have focused their attention on how to characterize the nature of the rights implicated, and therefore the level of scrutiny warranted. This focus reacts to, and often follows, the current Supreme Court majority’s approach to questions about the rights of historically oppressed and marginalized …

Prefrontal Engagement In Cognitive Flexibility Across Paradigms, Katarina Kalajzic

Honors Scholar Theses

Cognitive flexibility is an executive function that involves dynamically adapting behavior in the face of changing environmental circumstances to achieve a particular goal. Disrupted in numerous psychiatric disorders such as Alzheimer’s disease, schizophrenia, OCD, and depression, the neural correlates of cognitive flexibility are not well understood. However, the prefrontal cortex (PFC) is strongly implicated in executive function and attentional control processes. Thus, we sought to examine the neural circuitry involved in distinct cognitive flexibility tasks – the attentional set-shifting task and the probabilistic 2-armed bandit task. Through optogenetic suppression, we targeted pyramidal neurons of the rodent medial prefrontal cortex, an …
