Matching The Stars To A Game Of Aggression, E. Chambers, Kristen Barnard

Electronic Proceedings of Undergraduate Mathematics Day

Region against region and army against army, we chart and battle among the stars! This paper studies the combinatorial game Aggression using graph-theoretic models. We focus on how winning strategies depend on the structure of the game graph, with particular attention to star graphs, matchings, and their disjoint union. The results presented here come from research conducted under the guidance of Dr. Kristen Barnard during the summer of 2025. We begin by introducing the game, describing the rule set used, and explaining how maps can be represented as graphs. From there, we examine how adjacency, placement order, and tie-breaking rules …

Strict Steiner Symmetrization For Polygons, Joseph Chai, Sun-Yung Alice Chang

Electronic Proceedings of Undergraduate Mathematics Day

In this note, we introduce a method called Strict Steiner Symmetrization (see Section 2.2) that is an altered form of Steiner Symmetrization that fixes the number of vertices. The context of this paper will be to prove the Isoperimetric Inequality in R2 via approximation by polygons. Specifically, to establish that among all n-gon domains in the plane, the regular m-gon, m ≥ n, uniquely minimizes the isoperimetric ratio and that the limit of this regular polygon (that is the circle) achieves equality in the isoperimetric inequality. This note is an extracted portion of my junior thesis (A Polygonal Proof of …

Huffman Tree Uniqueness, Elijah Diller, Adam Volk

Electronic Proceedings of Undergraduate Mathematics Day

The Huffman algorithm is a standard algorithm used to generate an optimized binary encoding of a string. Using this algorithm, it may be possible to come up with more than one possible optimized binary encoding for a given string, so the following question arises: what strings have a unique optimized binary encoding? By unique encoding, we mean a unique vertex-labeled binary tree resulting from the Huffman algorithm. We do not worry about edge labels as every binary tree corresponding to a string with n distinct characters has 2n−1 ways of assigning the edge labels and determining the code. This investigation …

Predator-Prey Dynamics: Exploration And Logistic Extension Of The Lotka-Volterra System, Amanda Maylath, Samuel Brensinger

Electronic Proceedings of Undergraduate Mathematics Day

The Lotka-Volterra system is a classic model of predator–prey interactions, capturing the interdependent growth and decline of two species. Using a dynamical systems approach, we identify fixed points, linearize the system via the Jacobian, and analyze phase space trajectories to determine stability and long-term behavior. This analysis provides insight into predator-prey dynamics without requiring explicit solutions. We further extend the model by incorporating a carrying capacity for the prey, reflecting more realistic population dynamics.

The Recovery Of Meaning In A Digital Age: E-Discovery And The Renewal Of Judgment, William F. Hamilton

Journal of Technology Law & Policy

Modern litigation unfolds within a dense and expanding digital environment. Nearly every human activity now leaves behind emails, documents, metadata, collaborative communications, and machine-generated records that together form the factual foundation of contemporary litigation. This Article argues that electronic discovery is not merely a technical, managerial, or compliance process, but a core litigation practice concerned with the recovery, reconstruction, and rehabilitation of the factual world on which judgment depends.

Tracing the evolution of discovery from its twentieth-century roots to the present era of pervasive digital evidence, this Article shows how electronically stored information (ESI) continues to alter the dynamics of …

Who Has "Possession, Custody, Or Control" Of The Employee's Personal Mobile Device? Time For Amendments To The Federal Rules, Xavier Rodriguez

Journal of Technology Law & Policy

As mobile devices have become indispensable tools for professional communication, the distinction between personal and business data has blurred—creating critical challenges for litigators and organizations navigating discovery obligations. This Article explores the evolving jurisprudence surrounding whether and when a corporate defendant has “possession, custody, or control” over data stored on an employee’s personal mobile device. Drawing from a recorded podcast conversation and expanding on the legal foundations, I scrutinize the two primary frameworks courts use to analyze control—the “legal right” test and the “practical ability” test—and question their fitness in the context of modern mobile usage patterns.

This Article evaluates …

Exploring Early Career Public General Education K–6 Teachers’ Experiences With Their Training For Teaching Special Education Students In Inclusive Classrooms, Alexandra E. Ray

Doctor of Education Program Dissertations

Although Canada is often regarded as a leader in inclusive education, reports note that many students’ needs remain unmet and inclusion is typically implemented by placing students in mainstream classrooms with individualized accommodations. This qualitative phenomenological study explored the lived experiences of seven early career K–6 public general education teachers in Ontario (1–4 years of practice) as they engaged in inclusive education and prepared to teach students with special needs. Participants reported that teacher preparation coursework presented inclusive models only superficially, professional development was fragmented and insufficient prompting self-directed learning and structural constraints in schools limited individualized support. Teachers described …

The essay demonstrates how Bridgerton's widespread popularity has renewed interest in Georgian literature and provides an engaging and accessible entry point for undergraduate students to explore Evelina's themes of social anxiety, gender, and coming of age.

Reading Burney’S Mastectomy Letter: Presentist Thinking And Personal Responses In The Classroom, Heather Meek

ABO: Interactive Journal for Women in the Arts, 1640–1830

Frances Burney’s mastectomy letter, in its graphic and detailed depiction of the operation she underwent without anesthetic in 1811, does not always lend itself immediately to standard, scholarly classroom discussion. It tends, rather, to incite unusually intimate responses, as well as conversations about medicine and health today. In my teaching of the letter in literature courses at Université de Montréal over the course of the past 13 years, I have found that students are inclined to seize upon the subject of breast cancer as especially contemporary in its relevance and to share their own anecdotal knowledge of the disease. I …

The Wanderers: Teaching The Literature Of Migration And Exile, Linda Zionkowski

ABO: Interactive Journal for Women in the Arts, 1640–1830

In our current global landscape, exile—or forced, often permanent migration—appears a central rather than tangential experience, being driven by armed conflict, environmental destruction, economic collapse, and political repression. The climate on many university campuses reflects students’ awareness of and concern for the situation of displaced populations, and this awareness has influenced political discourse and political action inside and outside the classroom. My course titled “The Wanderers: Teaching the Literature of Migration and Exile” begins with  Frances Burney’s narration of exilic experiences in her life writings and The Wanderer. Burney’s texts offer a conceptual foundation for exploring instances of physical …

The Secret(S) To Success: Genlis’S Guide To Raising A Foolproof Daughter, Jennifer Law-Sullivan

ABO: Interactive Journal for Women in the Arts, 1640–1830

Abstract: “The Secret(s) to Success: Genlis’s Guide to Raising a Foolproof Daughter”

Stéphanie-Félicité de Genlis’s Adèle et Théodore ou lettres sur l’éducation, first published in 1782, is an epistolary conduct novel that examines the question of how best to educate girls. Attempts to answer the question were exceedingly in vogue in the late 18^th century and can be traced back to Fénelon’s 1681 Traité de l’éducation des filles. Genlis’s novel offers a robust critique of previous education treatises, Rousseau, and a patriarchal society that did little to educate girls and mothers. She couches her critique in a …

The Open Wiki Of Electrochemical Methods (Owem): A Community-Driven Educational Resource, Anderson Fuller, Devin Rappleye

Reviews, Analyses, and Instructional Studies in Electrochemistry (RAISE)

The traditional resources for learning electrochemical methods—textbooks, academic literature, and university coursework—remain essential but are limited in accessibility, update frequency, and practical usability. This paper introduces the Open Wiki of Electrochemical Methods (OWEM), an open-access, community-driven platform designed to complement these resources. OWEM organizes content into equations, definitions, methods, tutorials, and supplementary articles, with a heavy emphasis on experimental relevance. A case study on cyclic voltammetry demonstrates how OWEM consolidates foundational theory, lesser-known results, and practical guidance within a continuously maintainable framework to benefit the broader electrochemistry community.

Assessment And Intervention For Health Behavior Change In Primary Care Across The Lifespan: A Guide For Residents In Primary Care Specialties, Stacy A. Ogbeide, Alexis Ramos, Bridget Murphy, Angel Ogbeide

HCA Healthcare Journal of Medicine

More than 45% of Americans have at least 1 chronic disease, with chronic disease also being a leading cause of death in the United States. In primary care settings, about 75% of visits are for management of multiple chronic diseases. Due to the increasing medical complexity of patients who present to primary care, these numbers make it more challenging for Primary Care Clinicians (PCCs) to manage these conditions alone and point to the need for innovative solutions to chronic disease care. One evidence-based innovation is team-based care to improve the treatment of these conditions. Clinicians such as clinical pharmacists, registered …

Autoimmune Hemolytic Anemia Associated With Leptospirosis: A Rare Complication, Anum Waqar, Furqan Mazhar, Mahrukh Afzal, Sadia Razzaq, Sana Ijaz

HCA Healthcare Journal of Medicine

Introduction

Autoimmune hemolytic anemia (AIHA) is rare but potentially life-threatening complication of leptospirosis, a zoonotic infection caused by the Leptospira species. Autoimmune hemolytic anemia occurs when the immune system targets red blood cells, resulting in hemolysis and anemia. The relationship between leptospirosis and AIHA is uncommon and often under-recognized, which can delay diagnosis and management. This case highlights the importance of considering hematologic complications in leptospirosis.

Case Presentation

A 23-year-old male presented with low-grade fever, productive cough, shortness of breath, jaundice, and pallor for 15 days. On examination, he was pale and icteric with bilateral chest crepitations. Laboratory studies showed …

A Case Report Of Mesalazine-Induced Pulmonary Injury In A Patient With Ulcerative Colitis, Vasileios Paraschou, Vasileios Papavasileiou, Ilektra Voulgareli, Vasilios Tzilas

HCA Healthcare Journal of Medicine

Introduction

Mesalazine (5-aminosalicylic acid) is widely used as a first-line therapy for ulcerative colitis (UC) due to its efficacy and safety profile. Rarely, it can cause pulmonary toxicity with variable clinical and radiologic manifestations, making diagnosis challenging.

Case Presentation

We report the case of a 52-year-old woman with UC who developed persistent fever and progressive exertional dyspnea following escalation of mesalazine dosage. Imaging revealed diffuse bilateral ground-glass opacities, while infectious and UC-related pulmonary causes were excluded. Pulmonary function testing demonstrated restriction and markedly reduced diffusing capacity. Following mesalazine discontinuation and initiation of corticosteroid therapy, the patient experienced rapid symptomatic, functional, …

An Unusual Case Of Bilateral Upper And Lower Oral Cavity Cysts In A Newborn, Frances Rodriguez Lara, Jillian L. Chen, Jennifer N. Shehan, Jessica R. Levi

HCA Healthcare Journal of Medicine

Background

Oral mucosal lesions in newborns have a broad differential diagnosis, ranging from benign, transient conditions to potential early signs of systemic disease. Most of these lesions are resolved without intervention, but delayed recognition can lead to complications, such as airway obstruction. Early identification is crucial for appropriate management. This case report discusses an unusual presentation of multiple oral mucosal cysts in a newborn, emphasizing the challenges of diagnosis and management.

Case Presentation

A 1-day-old male was evaluated at Boston Medical Center for cystic oral lesions identified during newborn screening. The infant was born at 36 weeks and 2 days’ …

Impact Of Pre-Existing Psychiatric Conditions On Trauma Outcomes: A National Analysis, Kelly Mckenney, Marie Ugo, Sindhura Kompella, Clara Alvarez, Ilko Luque

HCA Healthcare Journal of Medicine

Background

Understanding the impact of psychiatric pre-existing conditions (PsyPECs) on trauma outcomes is crucial, as trauma is the leading cause of mortality for Americans aged 1-45. Although previous regional studies have shown higher mortality rates and longer hospital length of stay (H-LOS) for injured patients with PsyPECs, this has not been studied at the national level. The purpose of this study is to identify the PsyPECs associated with mechanism of injury and other outcomes in adult patients admitted for trauma in the United States’ trauma centers.

Methods

Data were extracted from the National Trauma Data Bank (NTDB). There were 5301 …

Time For A New Whole-Person Care Pathway For Chest Pain Admissions, Dana Kajan, Sabbir Mirza, Alexander M. Ruiz, Anthony Degennaro, Mohamad S. Saad

HCA Healthcare Journal of Medicine

Background

Emergency department (ED) visits for chest pain are common and costly, and ED workup often shows no clear cardiac etiology in low-risk patients. Emerging evidence suggests that social determinants of health (SDOH) such as loneliness, social isolation, and food insecurity contribute to cardiovascular outcomes and chest pain presentations.

Methods

We interviewed 114 patients (>18 years) presenting with chest pain and a thrombolysis in myocardial infarction (TIMI) score less than 4 at our community teaching hospital ED. Structured questionnaires assessed the SDOH triad of loneliness, social isolation, and food insecurity. Dependent variables included systolic blood pressure (SBP) at admission, …

Does Staff Education Increase Sequential Compression Device Utilization: A Retrospective Study, Devin Q. John, Vincent Lee, Akshay V. Daji, Hans Lapica, Connor Donley, Matthew J. Mccrosson, Nino Coutelle, Carlos Fernandez, Diego Lima

HCA Healthcare Journal of Medicine

Background

Venous thromboembolism (VTE) is a significant perioperative safety concern among orthopedic patients, with an incidence of 0.4%-1.0% and a substantial risk of chronic complications. Sequential compression devices (SCDs) are recommended for VTE prophylaxis, yet compliance remains suboptimal due to staff misconceptions. This study evaluates the impact of a resident-led educational intervention on SCD utilization among nursing staff in orthopedic postoperative care.

Methods

This retrospective study was conducted at 2 hospitals (HCA Florida JFK Hospital and HCA Florida Palms West Hospital). Nursing staff participated in a single educational session addressing SCD benefits, application techniques, and operational protocols. Data on SCD …

Organizational Psychology Theories In Graduate Medical Education: A Narrative Review, Mohamad S. Saad, Naim El-Aswad, Zeina Ghossoub, Relly Nadler, Serena Wasilewski

HCA Healthcare Journal of Medicine

Physicians and educators tend to be more versed in recognizing disease patterns and medical problems than in identifying malfunctioning patterns in the psychological aspects of their mentees and work environments. Just as hypertension and diabetes are the common soil for many acute medical problems, agency problems and organizational silos can lead to many acute managerial problems in graduate medical education (GME) settings.

Data show that most workers are lonely at work, which leads to negative emotions and undermines performance. Organizational problems seem to stem from an individual’s inability to align one’s motivation with the organization’s shared value. This can cause …

"I Don’T Know That You Can Do That Anywhere Else": The Role Rural College Towns Play In The Formation Of Queer Identity, Amy Mcdowell, Ryan J. Parsons, Julia Kraus

Journal of Queer and Trans Studies in Education

Challenging dominant narratives suggesting that rural spaces are inhospitable to LGBTQ+ identities, this study examines how queer individuals navigate space, rurality, and queerness in Oxford, Mississippi, a historically conservative college town. Drawing on oral histories from the Queer Mississippi digital archive, we argue that rural institutions of higher learning (rural IHLs) and the college towns they are embedded in serve as critical sites of queer identity formation. The rural college town provides a unique space where LGBTQ+ individuals from both within and outside the South navigate self-discovery, social networks, and belonging. We highlight the transformative role of these spaces in …

On- And Off-Field Impacts Of Foreign Players On Peruvian Liga 1 Football Teams, Juan Victor Aranibar, Claudio Rocha

Global Sport Business Journal

Despite the growing globalisation of football, little research has examined how foreign players create competitive advantage in non-traditional leagues. Using the Resource-Based View (RBV), this study explores the on- and off-field impact of foreign players in Peruvian Liga 1 clubs. Semi-structured interviews with 12 sporting directors, commercial managers, scouts, and coaches were analysed thematically, revealing five themes: physical characteristics, leadership and mental strength, cultural barriers, competitive salaries, and commercial blindness. Findings suggest that although foreign players provide valuable physical and psychological attributes, these are rarely sufficient to create sustained competitive advantage. More notably, clubs fail to capitalize on foreign players' …
