Faculty, Staff and Student Publications

Objective: Given the rising participation in high school athletics and the concerning trend of underreporting concussions, this study aims to identify and compare factors influencing sports-related concussion (SRC) awareness and reporting among youth athletes to their parents.'

Methods: Surveys were completed by 239 student-athletes (ages 13-19) and their parents, using a modified Rosenbaum Concussion Knowledge and Attitudes Survey-Student Version (RoCKAS-ST) and demographic questionnaires. Statistical analyses, including paired sample t-tests, ANOVAs, and Spearman's correlations, compared knowledge and attitudes between groups and examined demographic influences.

Results: Parents showed significantly higher concussion knowledge (CKI: t(230) = 5.18, p < .001) and safer attitudes (CAI: t(230) = 10.62, p < .001) than their children. Knowledge scores varied significantly by race and socioeconomic status, with White parents scoring higher than Hispanic and African American parents (F(3,224) = 8.97, p < .001). Child knowledge scores also differed by race (F(4,223) = 3.73, p = .006) …

The Moderating Effects Of Community Involvement On The Association Between Witnessed Community Violence And Mental Health Outcomes Among Black Adolescents, Curtisha Tamara Shacklewood

Theses and Dissertations

Black youth and adolescents are at a disproportionately high risk for experiencing community violence exposure (CVE) and the potential influence it may have on psychological functioning. Research posits that Black youth who experience community violence are at a significantly higher risk of experiencing elevated internalizing symptoms (e.g., depression) and externalizing symptoms (e.g., delinquency). Previous research has utilized the ecological model to investigate interpersonal protective factors that potentially buffer the effects of CVE, including parental support and family characteristics. However, there is little research that explores community-level factors, such as community activities (e.g., youth activities and parental perception of collective efficacy) …

Leveraging After School Programs As Resources To Support Adolescent Health And Wellbeing Within Underserved Communities: A Qualitative Study, Olivia Staples

Theses and Dissertations

Over the past decade, youth have shown a consistent rise in stress, major depression, anxiety, and suicide, with underserved youth (low-income, minoritized communities) at greatest risk of exposure to chronic stress, related outcomes, and less access to health services (APA, 2017). Afterschool programs (ASPs), which serve as important resources in underserved communities, can be a critical support for youth health and well-being (Afterschool Alliance, 2019). However, few studies have examined ways in which ASPs address the challenges underserved youth face across their ecosystem to promote youth resilience (Jones & Deutsch, 2011). Using qualitative interview data from staff and youth across …

Stem Integration In The Classroom: An Exploratory Case-Study On Teachers Defining Their Stem Identity And Role As A Stem Educator, Tawana Guillaume

Theses and Dissertations

The push for inclusion of science, technology, engineering, and mathematics (STEM) as a meta-discipline in K-12 education is recognition that the challenges faced by society require technology skills, interdisciplinary problem-solving, and an increased number of people entering STEM professions (Dare et al., 2014; English, 2016; Fan et al., 2021; Holstein & Keene, 2013; Roehrig et al., 2012, 2021; Sanders, 2008). The dissertation in practice explored STEM teacher identity and conceptions of STEM as a function of STEM professional experience outside of the field of education. The exploratory casestudy sought to identify the relationship between STEM career-based experiences – specifically the …

Improved Extraction And Detection Of Disinfection Byproducts, Impacts Of Wildland-Urban Interface Wildfires On Drinking Water, And Change In Disinfection Byproducts Over Time In Chlorinated Vs. Chloraminated Distribution Systems, Patrick Thomas Justen

Theses and Dissertations

Drinking water disinfection is critical to prevent the occurrence of waterborne pathogens in drinking water. However, disinfection causes the unintended formation of disinfection byproducts (DBPs) through the reaction of disinfectants (e.g., chlorine, chloramine) with natural organic matter (NOM), algal matter, or anthropogenic pollutants present in source waters. Exposure to DBPs is associated with increased bladder cancer, colorectal cancer, miscarriage, and birth defects. The U.S. EPA currently regulates eleven DBPs in drinking water—four trihalomethanes, five haloacetic acids, bromate, and chlorite. However, research shows that DBP related toxicity in drinking water is driven mainly by other, non-regulated DBPs, particularly iodinated DBPs and …

Coefficients Of The Characteristic Polynomial Of A Hypergraph And Their Combinatorial Properties, Utku Okur

Theses and Dissertations

We investigate the combinatorial properties of the characteristic polynomial $\phi_\mathcal{H}\ev{t}$ of a hypergraph $\mathcal{H}$, in particular, its coefficients. Due to a classical result of Jacobi, the generating function of closed walks at a vertex $u$ in a graph $G$ is determined by the rational function $\phi_{G-u}(t) / \phi_G(t)$. The connection between closed walks of $G$ and its characteristic polynomial has a known elegant proof via an application of Viennot's Heaps of Pieces framework, where cycles are taken as pieces and the concurrence relation is sharing a vertex. Here, we prove a bijection between heaps with a unique maximal piece containing …

Inspiring Girls To Fill The Blank Space In Stem: The Impact Of An After-School Coding And Robotics Club On Elementary Female Students' Engagement And Self-Efficacy In Computer Science, Lisa Guenther Wilbanks

Theses and Dissertations

The purpose of this action research was to describe how participation in an after-school coding and robotics program influenced elementary female students’ engagement and self-efficacy in computer science. According to a 2023 report from the National Science Foundation, in 2020 women earned only 21% of computer science degrees and 24% of engineering undergraduate degrees in the United States. As two of the fastest growing fields, the lack of female perspectives and experiences will continue to limit innovation in these areas. Studies show that gender gaps in engagement and self-efficacy in STEM begin long before students enter college and the workforce, …

Adipokines Mediate Fat-To-Ovary Communication To Regulate Oogenesis, Adipocyte Size, And Lipid Storage In Drosophila Melanogaster, Chad Herbert Simmons

Theses and Dissertations

Humans have complex signaling pathways that allow them to store and expend energy based on nutritional quality and availability. Inter-organ signaling is used to communicate nutrient availability between organs based on nutritional needs and the rate of cellular division. Our main overarching question is to investigate how fat-derived signals affect adipocyte morphology and the maintenance of stem cells in the ovary. While signaling pathways, like insulin and mTOR, and some adipokines that are involved in inter-organ nutrient sensing have been identified, the exact nutrient reliant mechanisms of stem cell maintenance are not completely understood. Using Drosophila melanogaster as a model, …

Thesis: Comparing Functional And Effective Brain Connectivity Metrics For Eeg, Diksha Srishyla

Theses and Dissertations

Background:Brain connectivity measures have been used to study communication between brain regions using electroencephalography (EEG). Functional and effective connectivity estimate the synchronization and the flow of information between regions, respectively. However, findings from studies using different measures to investigate similar connections do not converge. To guide the selection of functional and effective connectivity measures in future studies, we systematically compared a set of measures in the context of resting state EEG. We examined four functional connectivity metrics (coherence (Coh), the imaginary part of coherence (imCoh), the corrected imaginary part of phase lagged value (ciPLV), the debiased weighted phase-locking index (dwPLI)) …

Ai-Driven Autonomous Manufacturing: A Novel Taxonomy, Vision-Guided Planning, And Diversity-Aware Active Learning Frameworks, Ibrahim Yousif

Theses and Dissertations

Manufacturers face two opposing challenges: the escalating demand for customized products and the pressure to reduce lead times. Current manufacturing equipment, although reliable, operates at the limits of its technology and lacks adaptability to dynamic environments. This trade-off has been described as the optimal degree of automation, a threshold beyond which further automation incurs more cost than benefit. Smart manufacturing has introduced adaptive, data-driven systems, but many deployments still lack the contextual adaptability and autonomous decision-making required to handle unplanned disruptions. This underscores the need for intelligent, autonomous systems capable of real-time adaptation without costly reconfiguration, minimizing human intervention during …

Towards Accurate First-Principles Modeling In Heterogenous Catalysis: Ethane Dehydrogenation And Hydrogenolysis Over Pt Catalysts, Mubarak Ayo Bello

Theses and Dissertations

First-principles modeling has become central to heterogeneous catalysis research, offering mechanistic insight and guiding catalyst design, yet conventional approaches often struggle to accurately describe complex catalytic systems due to methodological uncertainties, simplified assumptions, and the structural diversity of nanoparticle catalysts. This dissertation addresses these challenges using ethane dehydrogenation (EDH) and hydrogenolysis (EH) over platinum catalysts as model systems. The first study benchmarks density functional theory (DFT) functionals against the random phase approximation (RPA) for the EDH network on Pt(111), identifying cost-effective functionals and demonstrating the efficiency of BEEF-vdW ensembles for capturing functional uncertainty. The second study (addressed in prior work) …

Hearing The Difference: Just Intonation Techniques Utilizing Distortion Product Otoacoustic Emissions In Viola Performance, Calj Green Umezono

Theses and Dissertations

Difference tones, also known as distortion product otoacoustic emissions, are the result of active phenomena in the human cochlea during the conversion of sound waves into bioelectrical signals. Difference tones make it possible to explore alternative musical tuning systems beyond the twelve-tone, equally tempered regime. Musicians have investigated difference tones since the 18th Century in Euro-American musical contexts, but their application has so far been limited in scope. Advances in science, technology, and music theory from the late 19th Century through the early 21st Century have given present-day violists the opportunity to more fully understand the virtues of difference tones …

Machine-Learning-Assisted Discovery Of Lattice Dynamics Signatures Of Sodium Superionic Conductors, Ogheneyoma Maxwell Aghoghovbia

Theses and Dissertations

Sodium superionic conductors are key to the development of all-solid-state sodium batteries. Discovery of new superionic conductors has traditionally relied on insights from material defect chemistry and the transition/hopping theory, while the role of lattice vibrations, i.e., phonons, remains underexplored. We identify key lattice dynamics signatures that govern ionic conductivity by analyzing the phonon mean squared displacement (MSD) of Na⁺ ions. By high-throughput screening of a dataset of 3903 Na-containing structures, we establish a strong positive correlation between phonon MSD and diffusion coefficients, providing a quantitative correlation between lattice dynamics and ion transport. To accelerate this discovery, we incorporate …

Multi-Perspective Feature Learning For Facial Expression Recognition In The Wild, Xiangyu Hu

Theses and Dissertations

With the rapid progress of deep learning, Facial Expression Recognition (FER) has seen substantial improvements in performance, particularly “in the wild” meaning real world conditions. Despite these advances, most existing methods extract features from facial images as the sole emotional cues, which limits the model’s ability to capture the full complexity of human emotional expressions.

In reality, facial expressions are composed of diverse and multi-perspective information, including appearance-based cues and geometric structural deformations due to activations of facial muscles. Depending exclusively on one type of representation may fail to exploit the complementary nature of these cues, an issue that becomes …

From Seapower To Shining Seapower, Michael Lee

Publications and Research

The liberal world order is dead: the United States has abandoned both the domestic and international institutional commitments that enabled it to function. How can liberal democracy survive in an increasingly hostile world? How can liberal democracies grow powerful enough to defend themselves without becoming the empires they fear? I argue that seapowers have historically represented a distinct kind of hegemon, that is more amenable to international cooperation, and democracy at home. Moreover, the transition from declining seapowers to rising ones has played a vital role in preserving a space for more liberal states (relative to their historical context), such …

New Approaches On Source Coding For Quantum Stochastic Sources And Implementation Of Quantum Fanout Gate, Rabins Wosti

Theses and Dissertations

The accurate computation of advanced quantum algorithms like Shor’s integer factorization, quantum phase estimation (QPE), and the quantum Fourier transform (QFT) requires quantum circuits of considerable size and depth. It is difficult to achieve reliable computation with deep quantum circuits due to the limited coherence times of the current noisy quantum devices. The quantum fanout gate is known to be a powerful primitive for reducing the depth of many quantum circuits (Høyer and Špalek 2003; Gottesman and Chuang 1999). Shallow or constant-depth quantum circuits are desirable for both near-term and fault-tolerant quantum computations as they reduce noise and allow faster …

Decorin Evokes A Pro-Lysosomal Pathway In Lymphatic Endothelial Cells, Gabriel J. Pascal, Dipon K. Mondal, Sadie Kim, Christopher Xie, Devanarayanan Siva Sankar, Jörn Dengjel, Renato V. Iozzo

Kimmel Cancer Center Faculty Papers

The lymphatic system is critical to the body's immune and circulatory system, and lymphangiogenesis, the development of new lymphatic vessels from pre-existing ones is a significant process capitalized upon by cancer during tumorigenesis. Decorin is a small leucine-rich proteoglycan which we have previously shown to be anti-tumorigenic and a suppressor of lymphangiogenesis. We have also shown that decorin exercises its anticancer properties through its ability to evoke autophagy. Through a comprehensive and unbiased proteomic analysis, we explored the implications of decorin exposure on protein expression within mouse lymphatic endothelial cells. We discovered that decorin enriches several protein pathways, notably proteasomal …

Saudi Medical Journal

ABSTRACT Objectives: To evaluate the association between Inflammatory bowel disease (IBD) and Ischemic heart disease (IHD). Methods: A retrospective cohort analysis included patients with and without IBD seen at the outpatient gastroenterology clinic of a large tertiary care hospital between January 2015 and October 2022. The primary outcome was the association between IBD and IHD, and the secondary outcome was predictors of IHD in patients with IBD. Results: The study included 400 patients; 291 were IBD patients, and 109 had other non-inflammatory GI disorders. The IBD group displayed significantly lower rates of hyperlipidemia (8.6% vs. 30.3%, p <0.001), diabetes mellitus (DM) (10% vs. 24.8%, p <0.001), and hypertension (11.7% vs. 32.1%, p <0.001) compared to the non-IBD group. Only 2.7% (n=8) of IBD patients developed IHD. Logistic regression analysis did not demonstrate a significant association between IBD and IHD ( p =0.932). Among classical risk factors, only hypertension (OR: 26.2, 95% CI: 2.14–661, p =0.016) and hyperlipidemia (OR: 10.5, 95% CI: 1.32–132, p =0.0405) significantly increased the risk of developing IHD among patients with IBD. Conclusion: In this cohort, there is no increased risk of developing IHD in patients with IBD compared to non-IBD patients.
