Analyzing Fungal Growth Dynamics Under Different Environmental Conditions Using A Lotka–Volterra Competition System, Maria Ordonez, Fabrio Araujo

Discovery Day - Daytona Beach

Fungi play a critical role in ecosystems as decomposers that recycle nutrients and maintain environmental balance. Their populations are influenced by multiple environmental factors such as temperature, humidity, nutrient availability, and interactions with other organisms. In this project, the Lotka–Volterra model is used to analyze how competing fungal species interact and how these interactions influence population dynamics over time. By modeling two fungal populations competing for the same limited resources, the equations illustrate how environmental conditions and competition coefficients determine whether one species dominates; both species coexist, or one species becomes extinct. The model provides insight into how changes in …

Assessing The Impact Of Various Factors On Hypoxic Response, Reese Kim, Allysa Hayden

Discovery Day - Daytona Beach

Hypoxia is a condition in which the body’s tissues are deprived of oxygen and has deleterious effects on cognition, perception, and performance. Hypoxia has a myriad of symptoms such as euphoria, difficulty concentrating, headache, fatigue, nausea, dizziness, tunnel vision, and more. Outward signs of hypoxia include cyanosis (blueing of the fingertips and lips), tremors, loss of coordination, pallor, and complexion change, and can be used to notice the onset of hypoxia in others. Many factors are known to contribute to the manifestation of hypoxia, namely altitude, exposure duration, and certain physiological conditions such as heart problems and low blood flow …

Honeybee-Inspired Swarm Intelligence For Autonomous Adaptability Of Martian Infrastructure, Morgan Kendall

Discovery Day - Daytona Beach

Current research in autonomous space systems primarily relies on centralized control or swarm methods designed for fixed mission scenarios. These approaches lack the flexibility needed for long-duration Mars operations, where infrastructure must adapt to changing conditions, evolving mission goals, and limited human oversight. This creates a critical gap in developing autonomous systems capable of continuous self-organization. This gap is being addressed by developing a biologically inspired, adaptive Martian infrastructure using swarm intelligence. The scope includes key system domains such as power distribution, communication networks, and surface logistics. Agent-based modeling software will simulate infrastructure components as autonomous agents that evaluate local …

Asymptotic Enumeration Of K-Bounded Functions Using Toeplitz Matrices, Tiago Cavalcante Trindade, Pedro Martineli

Rose-Hulman Undergraduate Mathematics Journal

We introduce the concept of $(\alpha, \lambda)$-bounded functions, characterized by limited local variation, which is especially useful in discrete sets. Initially, we formally define these functions and investigate their fundamental properties, highlighting significant differences from continuous functions. The main result obtained is the asymptotic estimate of $a(n, k)$, representing the number of functions from $[n]$ to $[n]$ that are $k$-bounded with respect to the Manhattan distance. The proof of this result combines Toeplitz matrices with a well-known inequality from graph theory.

Beyond The Indicators: Community-Defined Sustainability In Bario, Sarawak, Rhonwyn Hagedorn

Capstone Collection

This study examines how Kelabit community members in Bario, Sarawak, Malaysian Borneo define and practice sustainability within community-based tourism (CBT), and how these local understandings align with or diverge from the United Nations Sustainable Development Goals (SDGs). The study used a thematic analysis drawing on fifteen semi-structured interviews with Kelabit community members, supplemented by tourist questionnaires and document analysis of online tourism materials. Four themes emerged: sustainability as collective stewardship; community decision-making and collaboration; cultural identity as the core of tourism; and equity, participation, and the limits of growth. Findings suggest that Kelabit community members hold a holistic, relational, and …

From Crisis To Reform: How The 1918 Influenza And Covid-19 Pandemics Redefined The Relationship Between Nurses And The American Healthcare System., Anh N V Le

Undergraduate Research and Scholarship Symposium

The 1918 Influenza and COVID- 19 pandemic have become two major public health crises that reshaped the role of nurses in the America healthcare system. Although a hundred years apart, both pandemics revealed how deeply the country depends on nurses during emergencies without proper and efficient strategies. This paper argues that these pandemics acted as turning points that redefined the social contract between nurses and the U.S. healthcare system. By examining historical context, nurses’ responsibilities, public perception, and long-term effects, this research show how pandemics expanded nurses’ authority while also exposing long-term weakness of the systems. In 1918, nurses were …

Bioethics As Seen On Stage: Can Theater Change The World?, Sarah J. Cavanaugh

Undergraduate Research and Scholarship Symposium

This research paper investigates the extent to which theatrical works can influence societal reform through the depiction of bioethical dilemmas through time, analyzing performative theater’s ability to change the world through great societal impact. By examining four plays from distinct historical periods—Philoctetes by Sophocles (409 BCE), Whose Life is it Anyway? by Brian Clark (1972), The Waiting Room by Lisa Loomer (1994), and Next to Normal by Brian Yorkey (2010)—this study analyzes how theater has consistently engaged with evolving issues of medical ethics and patient autonomy. Each play presents ethical conflicts reflective of the medical and social dilemmas of …

Everything I Learned About Teacher Noticing I Learned From Yoga Teacher Training, Grace Giorgio

Communication and Theater Association of Minnesota Journal

The following activity promotes teacher noticing as a pedagogical tool for teachers in training, with a focus on the public speaking classroom. Many students enter the public speaking classroom filled with performance anxiety and fears of how their peers will perceive them. When a teacher can tap into these concerns via by noticing how students are reacting in the moment, they can assuage those anxieties and fears. Hence, teaching instructors effective teacher noticing in teacher training improves the classroom experience for teachers and students alike.

Exploring The Seams Of Performance: Performance Studies & Theater Praxis, Sarah Kozinn

Communication and Theater Association of Minnesota Journal

The exercise aims to use a taxonomy of performance, as theorized by Richard Schechner in his essay “Drama, Script, Theatre, and Performance,” to think analytically about what performance is. (Part of the goal is to “make strange” what students, most often, think they already know by giving then tools to better define and identify the spectrum of what is termed “performance.”)  Students will articulate the porously bounded areas of drama, script, theatre, and performance, teasing apart and developing a definition of what defines theatre as theatre in relation to how they define performance.  Through this, students will develop an analytic …

The Chameleon Experience: Queer Identity, Mental Health, And Transformation, Cameron Penny

Communication and Theater Association of Minnesota Journal

In this autoethnographic piece, I examine the correlation between queer identity and mental health through reflective analysis of my own experiences within a Western socio-cultural setting. I expand external perspectives on the queer experience by highlighting the normalization of queer prejudice and its adverse impact on self-image. I share how the religious praxis of Catholicism enforces binary conformity by promoting dichotomous thinking that simultaneously constricts queer expression and subjugates implicit biases. In tandem, I utilize autoethnography as my medium because it provides a unique outlet to raise awareness for chronically stigmatized identities by centering marginalized voices (Atay, 2011; Chavez, 2013). …

Best Practices And An Agenda For Research In Benefits Communication, Kristi Egbert, Anne Kerber

Communication and Theater Association of Minnesota Journal

Benefits communication is information an employer/organization provides to employees about the types of benefit plans offered and information about them (i.e., health insurance, retirement, vacation time). Despite its importance to jobs across all sectors of the workforce, there is a dearth of current academic research regarding benefits communication. This paper defines benefits communication, examines its impact on organizations and workers, and explores existing research on best practices. Findings underscore the complexity of benefits material and emphasize the need for simpler and clearer language, employee-preferred formats, and adequate time for employees to review information and receive guidance from a knowledgeable source. …

State Of The World: Presidential Rhetoric At The United Nations, Jason A. Edwards, Zoe Hess Carney, Kory Hoyt

Communication and Theater Association of Minnesota Journal

In 1982, President Reagan spoke to the United Nations General Assembly (UNGA) for the first time. In doing so, Reagan established a presidential tradition that, we argue, created a new genre of presidential rhetoric. Like the State of the Union speech, presidents, in this address, outline their vision for U.S. foreign policy and global politics for the coming year. Specifically, presidents mediate on the history and values of the United Nations, assess the current state of global affairs, and offer policy recommendations to deal with those issues. Examining presidential rhetoric at the United Nations offers a heuristic to understand U.S. …

Amplifying Community Voices In Climate Policy: Attitudes On Climate Change And Decarbonization In Cache County, Cristina Chirvasa, Rivkah Haubner, Stacia Ryder

Transforming Communities

Climate change is altering global ecosystems and imperiling human health, but knowledge of these impacts does not always translate into adaptation and mitigation action. Many solutions fall under decarbonization, or the reduction and capture of atmospheric carbon. These actions are increasingly developed at more localized, sub-state levels. Thus, understanding the attitudes of Cache County, Utah, residents, including students and faculty at Utah State University, toward different decarbonization techniques will be important to building successful climate action plans and policies. Here, as part of a large-scale collaborative group of different on-campus departments and community partners, we held focus groups to examine …

Confidence Versus Competence: Addressing Nursing Knowledge Gaps In Catheter Care To Reduce Catheter-Associated Urinary Tract Infections, Leslie Anne Villanueva Bautista

Master's Projects and Capstones

Catheter-associated urinary tract infections (CAUTIs) remain among the most prevalent and preventable healthcare-associated infections (HAIs), contributing substantially to patient morbidity, mortality, prolonged hospitalization, and healthcare expenditures. Most hospital-acquired UTIs are related to urinary catheters, and this burden costs the United States alone an estimated $340 to $450 million annually (Yang et al., 2022). CAUTIs are UTIs that occur in patients with indwelling urinary catheters. This quality improvement project aimed to increase adherence to existing bladder scanning protocols and strengthen urinary catheter care to prevent CAUTI. Baseline staff nurse knowledge was obtained, and reinterpretation of the facility’s existing protocols and bundles …

Bcg Overexpressing Ag85b Reprograms Host Immune Response Through Coordinated Transcriptional Networks, Vivek Chauhan, Rakesh Kumar, Raja Veerapandian, Enrique I. Ramos, Chinnaswamy Jagannath, Shrikanth Gadad, Subramanian Dhandayuthapani

School of Medicine Publications

Antigen 85B (Ag85B), an immunodominant protein secreted by Mycobacterium tuberculosis (Mtb), induces robust T-cell-mediated immunity in host cells. Previous studies have demonstrated that recombinant BCG strains overexpressing Ag85B (BCG85B) confer significant protection against tuberculosis in mouse models. This study hypothesized that enhanced protection by recombinant BCG85B results from modulation of host immune gene expression by the Ag85B antigen. To test this, RNA-seq analysis was performed on splenocytes from mice immunized with the wild-type BCG (BCG-WT) and BCG85B strains. Differentially expressed genes (DEGs) in the splenocytes of BCG85B-immunized mice indicated upregulation of immune-related KEGG pathways, including Th1/Th2 and Th17 differentiation, NF-kappa …

From Prairie To Practice: Environmental Controls And A Forensic Taphonomic Framework In Southeastern Nebraska, Jessica F. L. Gammage

Nebraska Academy of Sciences: Programs and Proceedings

Forensic taphonomy examines the postmortem processes that affect human remains, but much of the existing research has been developed in environments that differ significantly from those encountered in the Central Great Plains. This creates limitations when applying established models to regions like southeastern Nebraska, where decomposition is shaped by tallgrass prairie ecosystems, loess-derived soils, and strong seasonal variability. Addressing this gap is important for improving the accuracy and reliability of medicolegal interpretations.

This study evaluates how environmental conditions influence decomposition in southeastern Nebraska and proposes a regionally grounded framework for forensic taphonomic research. Drawing on existing literature, regional ecological data, …

Draining The Risk, Holding The Line: A Nurse-Driven Approach To Catheter-Associated Urinary Tract Infection Prevention, Thy Nguyen

Master's Projects and Capstones

Catheter-associated urinary tract infections (CAUTIs) remain among the most common preventable healthcare-associated infections, with CMS eliminating reimbursement for hospital-acquired cases since 2008. Within a five-unit, high-acuity microsystem at an urban acute care hospital, four CAUTIs were documented between January and July 2026 despite established prevention protocols. Adherence gaps were identified in catheter necessity assessment, maintenance practices, and nurse-driven removal protocol use. This quality improvement project was guided by the Johns Hopkins Evidence-Based Practice framework and Lewin's Change Theory. A targeted nursing education intervention addressing bladder scanning, dependent loop identification, and catheter care bundle adherence was implemented across the microsystem over …

Improving Adherence To Remote Patient Monitoring (Rpm) For Patients With Hypertension, Chioma Udegbune

Student Scholarly Projects

Practice Problem: Hypertension is a leading contributor to cardiovascular disease, and suboptimal adherence to remote patient monitoring (RPM) limits opportunities for timely intervention and effective blood pressure management in outpatient primary care.

PICOT: The PICOT question that guided this project was: Among outpatient clinic nursing staff responsible for remote patient monitoring (RPM) in adults with hypertension (P), how does implementation of a structured nurse-led education and reminder protocol (I), compared to standard RPM practices consisting of routine onboarding and passive reminder processes (C), influence patient adherence to RPM protocols (O) over a 10-week period (T)?

Evidence: Evidence supports nurse-led education, …
