Training Vs. Reality: The Challenges Of Preventing Heat-Related Illness In Migrant Farmworkers, Sonya Homami

Rowan-Virtua Research Day

Background: Heat‑Related Illness (HRI) is a major occupational hazard for migrant farmworkers, who are 35 times more likely to die from HRI than workers in other industries. Although HRI training aims to improve prevention knowledge, its effect on actual HRI outcomes is unclear.

Methods: Following PRISMA guidelines, a systematic review of PubMed, Embase, and Web of Science identified studies evaluating HRI training and reporting HRI prevalence or related symptoms. Fifteen studies met inclusion criteria.

Results: HRI training did not reduce HRI prevalence or provide protective effects. Training increased reporting of workplace injuries and concern about HRI. Despite high training uptake—over …

Hydration During Emergency Medicine Shifts: An Overlooked Component Of Cognitive Performance, Well-Being, And Systems Design To Fail To Plan For Shift Hydration Is To Plan To Fail With Shift Hydration, James Espinosa, Alan Lucerna, Swet Patel, Robin Lahr, Sergey Medlenov, Adam Kandil, Frank Wheeler, Wayne Tamaska, James Lee, Neel Parikh, Henry Schuitema

Rowan-Virtua Research Day

Emergency Medicine (EM) clinicians work prolonged, cognitively demanding shifts in environments characterized by unpredictability, interruptions, and high decision density. While fatigue, burnout, and circadian disruption have been widely studied, hydration during active clinical shifts has received little focused attention. Evidence from cognitive, military, and sports physiology literature demonstrates that even mild dehydration can impair attention, working memory, mood, and reaction time. Despite these findings, hydration in Emergency Medicine is typically treated as an individual behavior rather than a systems-level design consideration. This review synthesizes relevant physiologic and performance literature, identifies cultural and structural barriers to hydration during EM shifts, and …

Listening To The System: Reframing Emergency Department Noise: The Case For Noise As A Real-Time Operational Signal In A Complex Adaptive System (Cas), James Espinosa, Alan Lucerna, Henry Schuitema

Rowan-Virtua Research Day

Emergency Department (ED) noise has historically been framed as an occupational and environmental hazard requiring mitigation. And this is still true—but not complete. Early work focused on exposure reduction and spike identification. Subsequent mapping studies demonstrated spatial and temporal differentiation in ED acoustic load. We propose an expanded conceptual model: acoustic variability may function not only as a hazard, but also as a real-time signal of operational turbulence within the ED as a complex adaptive system (CAS). Drawing on human factors, alarm fatigue, resilience engineering, and complexity science, we synthesize existing literature and institutional experience to identify a critical gap—noise …

Detecting Early Operational Turbulence In The Emergency Department Using Fourier And Wavelet Analysis: A Conceptual Framework For Signal-Informed Anticipation And Prediction In The Ed Complex Adaptive System, James Espinosa, David Ho, Alan Lucerna

Rowan-Virtua Research Day

Background:

We theorize that Emergency Departments (EDs) function as complex adaptive systems characterized by nonlinear interactions, oscillatory demand patterns, and abrupt phase transitions from stable flow to turbulent states. Traditional dashboards rely on threshold metrics that detect instability after degradation becomes visible. Many ED data streams are significantly retrospective as well as compression-averaged into temporal systems such as days, months, quarters or even years. Signal processing methods—particularly Fourier and wavelet analysis—offer the  framework for detecting latent oscillatory shifts preceding overt operational change from laminar to transitional to turbulent flow states. This could lead to better methods of adaptation.

Conceptual Framework: …

Helping Waldo (The Poster) Be Found: Teaching Search Literacy, Discoverability And Search Engine Optimization As Core Scholarly Skills In Graduate Medical Education, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background: In modern academic medicine, trainees are taught how to search the biomedical literature but rarely taught how to structure their own scholarly work so that it can be discovered.

Objective: To propose a concise educational module that teaches residents the principles of search literacy and scholarly discoverability.

Methods: A conceptual curriculum framework was developed drawing on literature from information science, medical education, and diffusion theory. The module introduces the paired competencies of 'Finding Waldo' (literature …

The Safety Paradox Of Emergency Department Shift Length: Why The Relationship Between Hours Worked And Patient Safety Is More Complex Than It Appears, James A. Espinosa Md, Alan Lucerna

Rowan-Virtua Research Day

Background: Emergency department shift duration has long been debated as a determinant of patient safety. While longer shifts may increase cognitive fatigue, shorter shifts may increase the frequency of patient handoffs, which themselves introduce communication risk. Objective: To conceptualize emergency department shift length as a safety paradox arising from the balance between fatigue and handoff-related communication risks. Conceptual Framework: We propose the Emergency Department Shift Length Safety Paradox model illustrating the nonlinear relationship between shift duration and patient safety. Implications: Optimal shift design may depend on balancing fatigue risk and communication risk within a complex adaptive healthcare system. Conclusion: Emergency …

Do International Alumni Give Differently? A Study On The Alumni Philanthropic Perspective Of Trust And Key Relational Factors Affecting Attitude Towards Giving, John Held

Dissertations

Philanthropy plays a key role in the funding of institutions of higher education. Previous research has focused on domestic populations, exploring the antecedents and elements of philanthropy in higher education. The literature has yet to examine differences in these elements between domestic and international, or distance extremes, amongst alumni populations. This study investigates the perceptions and motivating factors influencing alumni who experience significant geographic separation from their Higher Education Institution (HEI) and their philanthropic support for their alma mater. The conceptual model includes factors at the organization-to-organization, person-to-organization, and person-to-person levels and their moderating effects on the relationship between trust …

Genetic Analysis Of Triplicated Genes Affecting Sex-Specific Skeletal Deficits In Down Syndrome Model Mice, Kourtney Sloan, Kristina M. Piner, Pathum Randunu Nawarathna Kandedura Arachchige, Charles R. Goodlett, Yann Herault, Gayla R. Olbricht, Joseph M. Wallace, Randall J. Roper

Mathematics and Statistics Faculty Research & Creative Works

Down syndrome (DS) is caused by the triplication of human chromosome 21 (Hsa21), resulting in skeletal insufficiency (low bone mineral density) and altered bone development. DS mouse models recapitulate these deficits, including sexual dimorphism in long bone alterations. Historically, Ts65Dn mice provided much of the insight behind DS-related skeletal deficits with ∼100 trisomic orthologous genes, but there are concerns about the genetic fidelity in this model due to the included triplication of genes not homologous to Hsa21. A new DS model, Ts66Yah, subtracted the non-Hsa21 homologous trisomic genes from Ts65Dn but has not been evaluated for long bone deficits. Comparing …

A Remote Sensing Approach To Identifying Zones Of Instability In Mine Tailings Impoundments Using Multi-Sensor Satellite Data, Arden K. Pierce

Honors Theses

Mine tailings impoundments are structures built to contain the chemical and sedimentary byproducts generated by ore extraction activities. In this common method of mining waste storage, the tailings can be pumped into containment ponds and held behind earthen embankments to prevent the release of hazardous substances into the surrounding environment. Monitoring environmental factors that influence the structural integrity of these impoundments is essential for identifying areas vulnerable to instability and failure. Soil moisture is a factor that can affect the stability of mine tailings impoundment structures. This study evaluates the relationship between satellite-derived soil moisture and surface deformation at mine …

Voltage-Sensor–Targeting Modulators Of Iks: Identifying Critical Functional Groups Of C28 Via Electrophysiology And Sar Modeling, Jiacheng Huang

McKelvey School of Engineering Graduate Student Theses & Dissertations

I_Ks (KCNQ1/KCNE1) channels are essential for cardiac repolarization, and their dysfunction contributes to arrhythmogenic disorders such as Long QT Syndrome type 1 (LQT1). Pharmacological activation of I_Ks has therefore emerged as a promising therapeutic strategy. C28, a recently identified voltage-sensor–targeting activator, has been shown to markedly shift KCNQ1/KCNE1 voltage dependence and enhance current amplitude, validating the voltage-sensing domain (VSD) as a druggable site. However, the structural determinants that underlie C28’s activity remain incompletely understood. In this study, we aimed to identify critical functional groups of C28 by screening a structurally diverse set of C28-like analogs and evaluating their …

Toward Vehicle-Agnostic Driving Signatures For Cognitive Impairment Prediction From Naturalistic Driving Data, Aadarsha Gopala Reddy

McKelvey School of Engineering Graduate Student Theses & Dissertations

This thesis studies whether naturalistic driving data can help predict binary Clinical Dementia Rating (CDR) status while accounting for differences across vehicles. The final analytic dataset comprised 26,968 participant-weeks from 304 participants. Weekly driving features were derived from real-world telematics data and combined with four demographic covariates. Primary model comparisons used leave-one-participant-out (LOGO) cross-validation, with one individual held out at a time and pooled participant-level metrics used as the main reporting surface.

The main comparison includes six model families evaluated on the same dataset under a shared LOGO framework. Performance remained modest overall. GRU-DANN had the highest participant-level ROC AUC …

Interaction-Aware Safe Planning For Human-Robot And Multi-Robot Systems, Haoyi Wang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Robots operating in shared environments must interact safely not only with static obstacles but also with other decision-making agents, including humans and other robots. In such settings, both safety and task completion depend on the ability to reason about interaction. Two major challenges arise. In human-robot interaction, future human behavior depends on latent internal factors, such as attentiveness and behavioral style, that are not directly observable to the robot. In multi-robot systems, decentralized reactive navigation can fail in cluttered environments when reciprocal interactions create deadlocks that prevent progress through narrow passages or bottlenecks. This thesis investigates these two challenges from …

Temperature And Environmental Implications On Ti3c2cl2 Mxene Degradation Process, Yang Yang

McKelvey School of Engineering Graduate Student Theses & Dissertations

MXenes, a rapidly emerging class of two-dimensional transition metal carbides and nitrides, have attracted considerable attention owing to their exceptional electrical, mechanical, and chemical properties. However, the inherent thinness of their atomic structure and the reactivity of their functional groups render MXenes susceptible to environmental degradation, whereby the lattice integrity is compromised and desirable material functionalities are dimin- ished. In this work, ex situ electron microscopy characterisation is performed on Ti₃C₂Cl₂ MXene specimens subjected to controlled gas environments — nitrogen gas (N₂) and air — at annealing temperatures of 200°C and 600°C, with …

Statistical Cryogenic Characterization Of Commercial 14nm Finfets For Analog Applications, Wesley Xi, Le Minh Long Nguyen, Vikram Magendar, Hiu Yung Wong

Faculty Research, Scholarly, and Creative Activity

About 100 structures were measured for both NMOS and PMOS. …

Automated Segmentation And Structural Remodeling Analysis Of Ipsc-Derived Cardiomyocyte, Bahareh Bahmani

McKelvey School of Engineering Graduate Student Theses & Dissertations

Cardiomyopathy is a disease of the heart muscle that can change cell structure, protein organization, and overall heart function. Some forms of cardiomyopathy are genetically inherited, including Hypertrophic Cardiomyopathy (HCM), the most common inherited cardiomyopathy affecting nearly 1 in 200 individuals1,2, and Desmin-Related Cardiomyopathy (DRM), a rarer disease that affects approximately 1 in 2000 individuals3. Changes in cardiomyocytes’ cellular structure define cardiomyopathies, and these changes are typically studied with fluorescence microscopy. However, manual image analysis is slow, labor-intensive, and often gives inconsistent results, especially when images are analyzed by non-experts. This thesis presents an automated computational framework for analyzing cardiomyocyte …

Improving Semantic Precision In Text-To-Image Diffusion Models Via Latent-Space Optimization And Semantically-Parsed Evaluation, Mohammad Rouie Miab

McKelvey School of Engineering Graduate Student Theses & Dissertations

Text-to-image diffusion models can produce visually impressive images from natural-language prompts, but they often fail to satisfy the detailed semantic constraints expressed in compositional prompts. Typical failure modes include omitted objects, merged entities, incorrect quantities, incorrect attribute binding, and leakage of one entity's attributes onto another. This thesis studies the problem of semantic precision in text-to-image generation: how faithfully a generated image satisfies the structured meaning of its prompt.   The thesis makes two linked contributions. First, it presents a training-free inference-time refinement method for diffusion-based image generation. The method operates directly in latent space during denoising and uses noun-phrase-aware cross-attention …

Largest 2-Regular Subgraphs In Complete S-Partite Graphs, Yiyang Jiang

McKelvey School of Engineering Graduate Student Theses & Dissertations

In this thesis, we focus on the class of complete $S$-partite graphs, for $S$ an undirected graph possibly with self-loops, and address the problem of finding largest $2$-regular subgraphs of these graphs, which can be formulated as an integer linear program. Roughly speaking, a complete $S$-partite graph is obtained by replacing every single node of $S$ with a number of nodes, preserving the edge/non-edge relations of $S$. Our motivation in studying largest $2$-regular subgraphs is rooted in the structural systems theory, particularly in the problem of finding largest subnetworks that can sustain controllability or asymptotic stability of the corresponding subsystems. …

Predicting And Decoding Allosteric Binding Sites Using Protein Language Models And Structure-Based Machine Learning: An Energy Landscape-Guided Explainable Ai Framework, Kamila Riedlová, Vít Skrhák, William G. Gatlin, Max Ludwick, Lucas Turano, Marian Novotný, David Hoksza, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

Computational prediction of allosteric binding sites in protein structures remains a persistent challenge, as these regulatory pockets evade detection by both sequence-based and structure-based algorithms. Both computational and physical origins of this predictive asymmetry remain insufficiently understood. In this study, we systematically examine the determinants of binding site predictability using a dual framework that integrates a fine-tuned protein language model and the structure-based method P2Rank as complementary tools probing a diverse data set of 453 human kinases, together with a physics-based interpretability layer derived from energy landscape frustration analysis. Both predictors exhibit a sharp and reproducible dichotomy on protein kinases, …
