Beyond The North Star: The Southward Flight Of Enslaved People To Mexico, Kayro Gonzalez

Theses (2016-Present)

When most people think of the Underground Railroad, they often picture brave individuals escaping the slave-owning South, seeking safety in the northern United States or Canada. However, it's essential to recognize that the fight for freedom went far beyond those regions. In 1830, Mexico abolished slavery, leading many escapees from enslaved areas across the United States. With freedom just a few miles away, hundreds of American slaves established several secretive and advanced routes into Mexico’s northern states, settling in newly founded free black colonies like San Lorenzo de los Negros and El Nacimiento de los Negros, among others. Using data …

Assessment Of Genes And Mirnas Expression In Alzheimer's Disease Samples Using Single And/Or Multiplex Preferential Amplification Pcr, Samanda F. Hickman

Theses (2016-Present)

Gene expression is measurable at the RNA and protein levels. It is a process by which genes produce functional products that are either non-coding RNAs or proteins. The non-coding RNAs or proteins of gene expression ultimately affect phenotype. Non-coding RNA (or mRNA) expression is measured by Northern blot or real-time quantitative PCR (RT-qPCR), while Western blot measures protein expression. Both require software to differentiate between the amounts of end products. Statistical analysis is employed to validate any differences among the measured values and to infer a correlation between the end products of various samples. There are several neurodegenerative diseases, including …

An Evaluation Of Reading Proficiency Examination College Completion Among Black Neurodiverse Women, Makayla J. Graham

Theses (2016-Present)

This study establishes the college completion experiences of Black neurodiverse women (n=53), a population historically rendered invisible in higher education research. Grounded in Dis/ability Critical Race Studies (DisCrit), Black Feminist Thought, the Black Feminist Disability Framework, and the Neurodiversity Paradigm, the research documents how intersectional identity, structural barriers, and mental health outcomes shape degree attainment. Data was collected through a mixed-methods online survey targeting this specific demographic. The findings demonstrate that college completion for this population is an act of resistance against racialized sexist ableism. Thematic analysis identified six central themes: Systemic Barriers in Higher Education, Intersectional Identity Burdens, Internal …

Recapitulating The Immune Microenvironment In Pediatric Brain Cancer: Preclinical Modeling Strategies., Adip G. Bhargav, Joseph S. Domino, David Akhavan, Jo Ling Goh

Manuscripts, Articles, Book Chapters and Other Papers

Primary brain and CNS tumors comprise the most common tumors in children and are the most common cause of cancer deaths in this population. Pediatric primary malignant brain tumors including high-grade glioma and medulloblastoma account for a significant proportion of these cancer deaths. Advances in the surgical management and adjuvant treatment paradigms have improved the prognosis of many patients with these tumors, but there remains a subset of treatment-resistant tumors or tumors with unique genetics aberrations and aggressive phenotypes that confer a poor prognosis. Immunotherapeutic strategies have demonstrated promise in pre-clinical studies and early clinical trials. However, high-fidelity evaluation of …

IMPORTANCE: Despite national recommendations, antiviral prescribing in emergency departments (EDs) for children at higher risk of severe influenza, such as those younger than 5 years and those with specific underlying conditions, remains low.

OBJECTIVE: To assess whether there were changes in antiviral prescribing for children at higher risk of severe influenza in academic pediatric EDs before the COVID-19 pandemic (2016-2020) vs the late pandemic period (2021-2023).

DESIGN, SETTING, AND PARTICIPANTS: This multicenter, cross-sectional study included influenza-positive children younger than 18 years presenting to the ED at 1 of 7 US pediatric academic hospitals participating in the Centers for Disease Control …

Emotion Regulation, Distress Tolerance, And Experiential Avoidance In Adults With Trichotillomania (Hair-Pulling Disorder) And Excoriation (Skin-Picking) Disorder, Valerie S. Swisher, Emily J. Ricketts, Tara S. Peris, Grant Jones, Erin Dunning, Stephanie Valle, Elizabeth Cavic, Christine Lochner, Dan J. Stein, Darin D. Dougherty, Joseph O'Neill, Douglas W. Woods, Jon E. Grant, John Piacentini, Nancy J. Keuthen

Psychology Faculty Research and Publications

Trichotillomania (TTM) and skin-picking disorder (SPD) are body-focused repetitive behavior disorders (BFRBDs) associated with deficits in emotion regulation, distress tolerance, and experiential avoidance. Their differential relations to TTM, SPD, and their comorbidity, and relative importance in predicting BFRBD outcomes is unclear. Therefore, this study compared these constructs in adults (n = 311) diagnosed with TTM (n = 112), SPD (n = 87), comorbid TTM and SPD (n = 40), and healthy controls (n = 72), and examined their relative importance in association with BFRBD outcomes. Participants completed questionnaires assessing BFRBD severity and impairment, functional disability, emotion regulation, distress tolerance, experiential …

Volumetric Differences Of Thalamic Nuclei Are Associated With Posttrauma Psychopathology, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Background

Previous investigations of whole thalamus and thalamic nuclei volumes in posttrauma psychopathology have been sparse and limited in scope and have yielded inconsistent results. To address this, volumetric estimates of whole thalamus and thalamic nuclei were obtained from structural brain magnetic resonance imaging scans from 2058 participants across 20 worldwide sites in the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) Posttraumatic Stress Disorder (PTSD) working group.

Methods

Thalamic volumes were compared in trauma-exposed participants with PTSD (n = 238), major depressive disorder (MDD) (n = 184), and comorbid PTSD+MDD (n = 618) and in trauma-exposed …

Warady, Vanessa Shaw, Larry A. Greenbaum

Manuscripts, Articles, Book Chapters and Other Papers

Children and young people with chronic kidney disease (CKD) are at risk for deficiency or excess of magnesium and trace elements. Kidney function, dialysis, medication, and dietary and supplemental intake can affect their biochemical status. There is much uncertainty about the requirements of magnesium and trace elements in CKD, which leads to variation in practice. The Pediatric Renal Nutrition Taskforce is an international team of pediatric kidney dietitians and pediatric nephrologists, formed to develop evidence-based clinical practice points to improve the nutritional care of children with CKD. PICO (patient, intervention, comparator, and outcomes) questions led the literature searches, which were …

Movement- And Posture-Based Measures Of Sedentary Patterns And Associations With Metabolic Syndrome In Hispanic/Latino And Non-Hispanic Adults., Marta M. Jankowska, Calvin P. Tribby, Paul R. Hibbing, Jordan A. Carlson, Mikael Anne Greenwood-Hickman, Dorothy D. Sears, Andrea Z. Lacroix, Loki Natarajan

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Sedentary behavior has been identified as a significant risk factor for Metabolic Syndrome (MetS). However, it is unclear if the sedentary pattern measurement approach (posture vs. movement) impacts observed associations or if associations differ for Hispanic/Latino communities, who have higher risk of MetS.

METHODS: Participants from the Community of Mine (CoM) study (N = 602) wore hip-based accelerometers for 14 days and completed MetS-associated biomarker assessment (triglycerides, blood pressure, fasting glucose, HDL cholesterol, waist circumference). Sedentary patterns were classified using both cutpoints (movement-based) and the Convolutional Neural Network Hip Accelerometer Posture (CHAP) algorithm (posture-based). We used logistic regression to …

Metabolic Acidosis And Cardiovascular Disease Risk In Children With Ckd., Denver D. Brown, Jennifer Roem, Kimberly Reidy, Susan Furth, Bradley A. Warady, Michal Melamed, Tammy Brady, Ckid Study Investigators

Manuscripts, Articles, Book Chapters and Other Papers

KEY POINTS: Metabolic acidosis may be associated with adverse cardiovascular disease risk. Prospective studies of the benefit of alkali therapy on cardiovascular disease risk are needed.

BACKGROUND: The link between metabolic acidosis (MA) and cardiovascular disease (CVD) outcomes has been studied in adults but not in children with CKD where MA is a common and early finding. Using longitudinal BP and cardiac measurement data, we evaluated whether low serum bicarbonate (a surrogate for MA) is associated with adverse CVD risk.

METHODS: This study used data from children age 1 year and older with eGFRs between 30 and 90 ml/min per …

The Impact Of Long-Term Exposure To Lip Cosmetics On The Fertility Of Female Drosophila Melanogaster, Neeka Oghli

Holster Scholar Projects

Are products marketed as safe to use, truly safe to use? Inspired by an article exposing the dangers of Tampax tampons, this study examines potential reproductive risks from consumer lip products marketed as natural and safe18. Drosophila melanogaster, a model organism with genetic and reproductive similarities to humans, was utilized to test the impacts of Rhode and Avène lip cosmetics. Avène’s Cicalfate + Lips Repair Lip Balm is the closest alternative to Rhode’s unscented peptide lip treatment, which was mindfully chosen to test if affordability comes at the expense of safety. Various concentrations of these products will be exposed to …

How Attention Related Brainwaves Vary With Performance On Speech-In-Noise Tasks, Akshat Viswanath

Holster Scholar Projects

Prior studies have found alpha (8-12 Hz) and beta (15-30 Hz) oscillations measured with EEG both increase in power when people are performing speech-in-noise tasks. In theory, variation in speech-in-noise performance could reflect the ability to segregate and neurally encode background versus foreground sounds. Here, we aim to examine how alpha and beta oscillations play a role in ignoring background sounds versus attending to foreground speech sounds. We had thirty-four healthy young adults perform a speech-in-noise task while we recorded brain signals using 64-channel EEG. Subjects were instructed to ignore the randomly varied background “noise” sounds that onset at the …

Effects Of Heat Stress And Depressed Feed Intake On The Cecal And Ileal Microbiota Of Broiler Chickens, Philip M. Campos, Elizabeth S. Greene, Monika Proszkowiec-Weglarz, Sami Dridi

Poultry Science Faculty Publications and Presentations

Chronic heat stress (HS) is known to depress feed intake (FI) and growth in broiler chickens, and may alter the gut microbiota and health, however, the amplitude and duration of each (HS and depressed FI) effect on gut microbiota is still unclear. This study aimed to determine the effects of chronic and acute HS on the cecal and ileal microbiota profiles. Broilers were subjected to thermoneutral (TN, 23 degrees C) or chronic cyclic HS (CHS, 8 h/d, 35 degrees C) condition from d29-42, and one group to acute HS (AHS, 2 h, 35 degrees C) at d42. To distinguish between …

BACKGROUND: Lower extremity amputations (LEAs) are medically, psychologically, and functionally devastating. The objective of our study was to evaluate region- and sex-specific differences of unilateral and bilateral LEAs across the United States (US) from 1990 to 2019.

METHODS: The Global Burden of Disease database was used to analyze years lived with disability (YLDs), prevalence, and incidence rates per 100,000 people for LEAs in the US from 1990 to 2019. Data were stratified into four US Census Bureau-defined regions: Northeast, Midwest, South, and West. Differences between regions and sexes were assessed, with statistical significance defined as p < 0.05.

RESULTS: From 1990 to …

Perioperative Antibiotic Administration Review: An Analysis Of Outpatient Surgeries At Ohiohealth Doctors Hospital., Rayyan Bhutta, Thomas Shneker, Samantha Currier, Alexander Caskey, Vincent Relli-Dempsey, Matthias Franzen, Samir Patel

Surgery Articles

INTRODUCTION: A vital part of preventing surgical site infections (SSIs) is perioperative antibiotic prophylaxis. Antibiotics must be administered within a certain window of time, usually 15 to 60 minutes prior to the surgical incision, for them to be effective. The most frequently utilized medication, cefazolin, can be administered quickly by intravenous push (IVP), but other medications, such as vancomycin and clindamycin, need longer infusion times. Antibiotic efficacy declines, and the risk of SSIs is increased when scheduling requirements are not followed. With special focus on time, dosage, and variation by surgery type, this study evaluates adherence to perioperative antibiotic administration …

Exploring Undergraduate Early Childhood Education Students' Conceptualizations Of Stem In Early Learning Contexts, Melany Spiehs

Educational Leadership Theses, Dissertations, and Student Creative Activity

Early childhood is widely recognized as a critical stage for STEM (science, technology, engineering, and mathematics) learning, yet many teachers feel underprepared to support children’s foundational knowledge and skills. This study examines how undergraduate students in early childhood education conceptualize STEM within early learning environments through an analysis of their coursework and field experiences. The investigation explores both students’ articulated beliefs about STEM (espoused theories) and how they enacted STEM teaching and learning in practice (theories-in-use). Data were drawn from course artifacts including journals, reflections, learning stories, lesson plans, and field observation notes. While much of the existing literature emphasizes …

Charting The Course: Understanding Key Elements, Stakeholder Insights, And Professional Perspectives In Establishing A Community College Court Reporting Program, Sherman P. Willis

Educational Leadership Theses, Dissertations, and Student Creative Activity

There is a national shortage of court reporters. This study investigates which elements and essential factors, according to industry criteria and stakeholder feedback, should form the foundation of a community college court reporting program. The research question was decomposed into two components: examining key elements from existing programs; and identifying best practices from judge surveys and essential program components from court reporter interviews.

A mixed analysis included National Court Reporters Association (NCRA)–approved program document review, quantitative surveys of Nebraska judges, and qualitative interviews with Nebraska court reporters. The survey evaluated judicial perspectives on fundamental program components. Semi-structured interviews gathered information …

Venturing Into Health, Rachel E. Sachs

Fordham Law Review

In recent years, the landscape of venture capital (VC) investment in healthcare technologies has been altered by the introduction of new types of VC firms: those that have emerged from hospital systems and health insurers. However, the legal literature has not yet analyzed these new VC firms, the role they may play in healthcare innovation, and how innovation law and policy ought to consider their involvement. Hospital system and health insurer VC firms operate very differently than traditional VC firms, even those that have historically developed healthcare specializations. Instead of simply investing capital into start-up firms, hospital system and health …

In this study we sought to first analyze the perceived achievement of complex thinking sub-competencies by majors, and we also aimed to investigate mean differences in the group of students coming from computer science and engineering related majors and by gender of the participants in complex thinking subcompetencies. 417 learners were part of this study, of which 65.7% were male and 34.3% were female. It was found that medical students perceived higher achievement in …

Evaluating Topological And Graph‑Theoretical Approaches To Extract Complex Multimodal Brain Connectivity Patterns In Multiple Sclerosis, Toni Lozano‑Bagén, Eloy Martinez‑Heras, Giuseppe Pontillo, Elisabeth Solana, Francesc Vivó, Maria Petracca, Alberto Calvi, Sandra Garrido‑Romero, Albert Solé‑Ribalta, Sara Llufriu, Ferran Prados, Jordi Casas‑Roma

Artículos científicos

Brain networks, or graphs, derived from magnetic resonance imaging (MRI) offer a powerful framework for representing the structural, morphological, and functional organization of the brain. Graph-theoretical metrics have been widely employed to characterize properties such as efficiency, integration, and communication within these networks. More recently, topological data analysis techniques, such as persistent homology and Betti curves, have emerged as complementary approaches for capturing higher-order network patterns. In this study, we present a comparative analysis of these feature-generation methodologies in the context of neurodegenerative disease. Specifically, we evaluate the effectiveness of Betti curves and graph-theoretical metrics in extracting features for distinguishing …

Subsistence As Resistance: Reconceptualizing The Theory Of Progressive Property To Incubate Resistance To Consumerism, D.S. Pensley

William & Mary Environmental Law and Policy Review

This Article reconceptualizes the theory of progressive property by juxtaposing legal theory with the empirical study of a subsistence economy in the U.S. Subarctic. Progressive property holds that owners are bound by obligations to non-owners as a means to achieve human flourishing. The theory is constrained by the primacy of private property in Western thought, and it also lacks the ecological ethic required for sustainability. Drawing from my fieldwork, I suggest that human flourishing must additionally incubate resistance to consumerism.

Federal statute, 16 U.S.C. § 3113, defines subsistence as “the customary and traditional uses by rural Alaska residents of wild, …

Let's Bee Pragmatic: The Economic Case For Neonicotinoid Regulation In Conservative States, Annie Rosenstein

William & Mary Environmental Law and Policy Review

The importance of bees in our ecosystem and to our food system in the United States cannot be overstated. In fact, 35% of global crop production depends on bees and other pollinating insects. Pollinators not only influence the production of many foods that we hold dear and rely on, such as apples, chocolate, potatoes, and coffee, but also influence the quality of these products.

Currently, the most insidious threat against bees in the United States is neonicotinoid pesticides (neonics). While neonics are effective at killing the target populations of beetles, aphids, and flies, they are equally effective at killing pollinators, …

Environmental Bankers: States Are Billing Fossil Fuel Companies For Extreme Weather Disasters, Kelly A. Adam

William & Mary Environmental Law and Policy Review

For decades, common law has been the pathway to remediation for environmental tragedies. Victims of traditional environmental harms can pursue justice through legal challenges like nuisance, negligence, and violations of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). However, climate change–induced natural disasters have led to the normalization of the “Act of God” exception; a policy provision commonly used in insurance law that excludes coverage for damage caused by unforeseeable natural disasters. Even so, real cities suffer the consequences of the real harm, whether insurance accepts it or not; so, who bears the burden of funding the recovery?
