Improving Blood Pressure Control Through Lifestyle Modification In African Americans Adults With Uncontrolled Hypertension, Tasha Leonard

Doctor of Nursing Practice (DNP) Scholarly Projects

African American adults have the highest incidence of uncontrolled hypertension (HTN), leading to premature cardiovascular death in Texas and worldwide. In a South Texas cardiac clinic, over 90% of African American adults with HTN also have obesity, compared with 55% of their Caucasian counterparts. The most prevalent factor affecting this group is poor understanding of blood pressure management, which leads to nonadherence to dietary and exercise recommendations, medication regimens, and blood pressure monitoring. The objective was to determine whether lifestyle modification using a hypertensive bundle would improve blood pressure management among African American adults in the clinical setting. The initiative …

Landfalling Hurricanes : Impacts Of Urban Growth On Rainfall And Flooding And Advances In Ai-Based Forecasting, Ankur Kumar

Dissertations

Hurricanes remain among the most destructive natural hazards, producing widespread impacts through extreme rainfall, flooding, and damaging winds. Rapid urbanization in coastal regions further amplifies these risks by modifying land surface characteristics and increasing population, while accurately forecasting hurricane evolution remains a major challenge. This dissertation addresses these challenges through three interconnected research objectives focusing on urbanization-induced hurricane modification, hydrological response, and AI-based hurricane forecasting. The first objective investigates how incremental multi-decadal urban growth modifies hurricane rainfall distribution and rainband evolution during Hurricane Harvey (2017). Convection-permitting WRF simulations demonstrate that realistic urban growth alters boundary-layer structure, storm-relative inflow, convective organization, …

Thermodynamics Of Bubble-Through Liquid-Core Nuclear Thermal Rockets, Dakota John Santana

Dissertations

Liquid-Core Nuclear Thermal Rockets (LNTR) were originally investigated in the 1960s. Exploratory efforts have thus far been relegated to preliminary models that illustrate proof-of- concept or identify theoretical limits. Collectively they would report ranges for 𝐼𝑠𝑝 between 1000 −2000 𝑠 and thrust-to-weights between 0.5 −6. This work expands a model for the Bubbler class of LNTRs into an engineering model suitable for design exploration and system model integration. Bubblers use centrifugal force to trap molten fissile fuel while bubbling propellant radially inward to cool structural members and achieve temperatures >4500 𝐾. The Bubbler model detailed herein, dubbed Fornax, expands the …

Improving Patient Adherence To Telehealth Appointments By Implementing A Bundle Intervention, Steve Erimwioghae

Doctor of Nursing Practice (DNP) Scholarly Projects

Background: Missed appointments undermine the benefits of telepsychiatry. An outpatient psychiatric practice in Texas reported a baseline no-show rate of 30.4%, exceeding national average and disrupting continuity of care, clinic efficiency, and revenue.

Purpose: Implement and evaluate a telepsychiatry adherence bundle—tiered automated reminders, structured pre-visit check-ins, and patient education—to reduce the no-show rate among adults receiving outpatient telepsychiatry care.

Methods: A pre- and post-quality improvement project, guided by the Plan-Do-Study-Act (PDSA) framework, delivered the bundle to all scheduled adult patients over eight weeks. De-identified appointment and demographic data were analyzed in SPSS using descriptive statistics and the …

A Guideline To Address Barriers To Mental Health Treatment Experienced By Law Enforcement Officers, Jacqueline Estrella

Doctor of Nursing Practice (DNP) Scholarly Projects

Problem: Law enforcement officers are exposed to repeated trauma on the job that may negatively affect their mental health. Officers may avoid seeking mental health treatment due to police culture, stigma, and other barriers which may increase risks for suicide, absenteeism, and maladaptive coping.

Objectives: Develop an evidenced-based guideline to address barriers law enforcement officers face in seeking mental health treatment.

Methods: The National Quality Measures Clearinghouse (NQMC) Domain Framework was used to guide a literature review to identify best practices suitable for a guideline. Articles were graded for strength based on the John Hopkins Nursing Evidence Based Practice (JHNEBP) …

Diffusion Of Excitons In Thin Films Of Quantum Dots, Dustin Roberts

Dissertations

Quantum dots are heavily used in modern devices, such as consumer television screens, lasers, medical sensors, solar cells, and quantum computing. Their tunability and photo-stability make them candidates for a variety of applications which formerly required either dyes or significant amounts of band structure engineering. Despite all of the current and active applications, there is a gap in the current literature with regards to how energy is transported through thin films of quantum dots, and what methods may be used to control transport direction and range. The goal of this dissertation is to help fill those gaps, towards the end …

Emotional Patterns In Conversational Social Media Using Graph-Based Context, Sai Sanjay Yerunkar

Master's Projects

Most social media datasets for emotion detection have not been constructed to account for conversational structure‚ so we investigate whether it carries signal for emotion prediction. Using Sentiment140 and GoEmotions Reddit threads‚ we construct their thread-based conversation graphs and compute the aggregated features of neighbors as well as the transformer and TF-IDF representations of comments. Connected comments are 4.5× more similar in emotions than expected by chance. Pairwise emotional similarity decays exponentially with geodesic distance (e.g.‚ after 2 hops). Pairs separated by a 30s timestamp difference have the highest emotional similarity. These results suggest that emotion is structured locally and …

Cost-Aware Predictive Routing For Vision-Language Models, Sahil Sait Naveed

Master's Projects

Vision-language models (VLMs) are increasingly used for multimodal tasks, but their inference costs vary widely across model tiers. This work presents a predictive routing framework that assigns each query to the most cost-effective VLM by using multimodal embeddings, clustering, and per-cluster model error estimates. Evaluated on six commercial VLMs, the selected router reduces average cost by about 49 percent relative to the quality-first setting on both validation and test. This comes with accuracy losses of 0.4 percentage points on validation and 0.9 on held-out test data. It also outperforms K-NN and ZeroRouter routing baselines while providing lowercost operating points than …

Adaptive Real-Time Fraud Detection Using Online Learning And Explicit Concept-Drift Detection, Purva Govind Tugaonkar

Master's Projects

Real-time credit card fraud detection faces challenges such as extreme class imbalance, delayed feedback, and concept drift in transaction streams. This project implements and evaluates an adaptive streaming fraud detection framework based on three methodologies: (1) online learning with incremental updates, (2) explicit conceptdrift detection using statistical monitoring, and (3) separate models for immediate and delayed supervision, combined with cost-sensitive learning and anomaly detection. The system processes the credit card fraud dataset in a batched streaming fashion, uses multiple online learners and ensembles. Experiments show that online, driftaware models maintain high recall on frauds while controlling false positives under imbalanced …

Modeling Sealed Deck Construction In Collectible Card Games Using Learning-To-Rank Approach, Michael Dinh Nguyen

Master's Projects

Artificial intelligence has demonstrated strong performance in complex decision-making domains such as chess and Go, motivating research into its application for games with even richer rules and combinatorial complexity. In collectible card games like Magic: The Gathering, deck construction from a constrained card pool is a critical and challenging task that requires evaluating card strength, synergy, and resource balance. This project explores whether machine learning, specifically learning-to-rank (LTR), can effectively model these human decision processes to construct competitive decks in a sealed format. The results found here can also be applicable to other areas of note, such as sports drafting …

Multi-Agent Path Planning And Optimization Using Q-Learning, Chirag Rudresh

Master's Projects

Robot navigation in a multi-agent setting requires a balance between safety and efficiency, especially in dense environments. In these two-dimensional spaces, the scope for geometric errors is much less and could lead to collisions or immobility. This project proposes to address the navigation task using a two-phase path planning pipeline that combines reinforcement learning and convex optimization in a scalable and robust manner. The first phase consists of generating diverse collision-free paths using a Q-learning agent that is trained on a visibility graph representation of the environment. The discretization of the environment using waypoint-based graphs allows the agent to train …

The Effect Of Cover Crop Management Strategies On Nutrient Availability In No-Till Corn, Emily C. Marsh

Theses and Dissertations--Plant and Soil Sciences

Cover crops are reported to have long-term soil health improvements, one of which is reducing erosion. However, popular cereal cover crops, such as rye (Secale cereale L.), have the potential to cause a yield penalty in the following corn (Zea mays L.) crop due to a reduction in available nitrogen. Legumes, such as Austrian winter pea (Pisum sativum L. var. arvense), are thought to reduce this yield penalty due to their capacity to fix nitrogen. Sulfur is another nutrient of interest, especially as rates of atmospheric deposition of sulfur have declined, leading to more deficiencies being …

The Global Privacy Frontier: Bridging User Expectations And Ai In Mental Health Technology, Salauddin Ahmed, Mohammad Asaduzzaman

Student Publications

This study examines privacy concerns in AI-driven mental health apps through the lens of Communication Privacy Management (CPM) theory, utilizing qualitative research of consumer opinions on Google Play Store. It explores how global consumers articulate privacy concerns, experience boundary turbulence in online conversations, and exhibit culturally oriented privacy expectations in this high-stakes emerging tech arena. Results indicate that users are most likely to voice concerns about control and transparency of data, with ambiguous privacy policies raising suspicion. Boundary turbulence narratives, e.g., improper use of data, are most directly related to loss of trust and app abandonment, highlighting critical challenges for …

How Wasteful Is Signaling?, Alex Frankel

Cowles Foundation Discussion Papers

Signaling is wasteful. But how wasteful? We study the fraction of surplus dissipated in a separating equilibrium. For isoelastic environments, this waste ratio has a simple formula: β/(β + σ), where β is the benefit elasticity (reward to higher perception) and σ is the elasticity of higher types’ relative cost advantage. The ratio is constant across types and independent of other parameters, including convexity of cost in the signal. A constant waste ratio characterizes the isoelastic class. In winner-take-all signaling tournaments with N candidates, exactly (N − 1)/N of the surplus dissipates—the same as in Tullock contests.

The Trade-Off Between Quality And Quantity: Evidence From A Field Experiment On Tutoring, Rohen Shaw

Cowles Foundation Discussion Papers

High-dosage tutoring has the potential to substantially raise adolescent academic achievement, but schools may lack the resources to deliver small-group tutoring frequently at scale. This paper studies the relative importance of tutoring group size (quality) versus tutoring frequency (quantity) using a randomized controlled trial in a Midwestern U.S. charter middle school. Students were randomized to a control group, tutoring twice a week in 2-student groups, or tutoring three times a week in 3-student groups, with equal total cost per student across the two treatment arms. The results show that tutoring in 2-student groups led to a statistically significant improvement in …

The First 1000 Days And Beyond: The Process Of Child Development, Orazio Attanasio

Cowles Foundation Discussion Papers

This paper reviews recent developments in the economics of human development, focusing on the early years of life as a critical period for shaping long-term outcomes. Early childhood development is inherently multidimensional: cognitive and socioemotional skills evolve dynamically and interact with health, nutrition, and environmental influences. Economists have contributed to this field by providing a conceptual unifying framework that highlights how key drivers of development reflect the choices of individuals operating under incentives and constraints. Within this framework, the paper emphasizes two central challenges: understanding the interactions among multiple dimensions of development and identifying causal links—particularly the effects of different …

The Asexual Assumption, Faith K. Whatley-Blaine, Michael S. Sinha

All Faculty Scholarship

Inclusion-focused dating shows such as ‘Love on the Spectrum’ feature individuals with developmental or neurological disabilities on a quest for love. Despite the focus on disability representation, these shows perpetuate stigma against the disabled community by fostering an infantilizing portrayal of individuals with disabilities. This portrayal undermines the premise of encouraging meaningful romantic relationships and reinforces the stigmatizing association of asexuality with disability. This framing aligns with the broader societal narrative that individuals with disabilities are incapable of or lack interest in participating in romantic relationships or physical intimacy.

The stigma that associates asexuality with disability extends beyond mere entertainment, …

Background: Functional seizures (FS) are paroxysmal episodes that phenotypically resemble epileptic seizures but are not associated with brain epileptiform discharges; they are also known as psychogenic nonepileptic seizures. The exact etiology and pathophysiology of FS is unknown; however, trauma and stress-related disorders are known risk factors.

Methods: We used a validated algorithm applied to electronic health records to identify individuals with FS in 6 international biobanks and hospital sites. We conducted a multisite FS genome-wide association study (GWAS) meta-analysis, including 10,910 FS cases (9040 predicted European ancestry [EA] and 1870 predicted African ancestry [AA]) and 664,500 (561,150 EA and 103,350 …

Spatial Evolution In Temporal Dynamics Of Hemodynamic Response Function In Human Superior Colliculi With Ultra-High-Resolution Mri At 9.4t, Nooshin J Fesharaki, Artemy Vinogradov, David Ress, Jung Hwan Kim

Faculty, Staff and Student Publications

The superior colliculus (SC) plays a crucial role in multisensory integration, visual information processing, saccadic target selection, visual selective attention, and decision making. In particular, the SC has a key role in oculomotor coordination, following a rostro-caudal organization. The rostral SC, which corresponds to foveal representation, is linked to fixation, microsaccades, smooth pursuit, and vergence adjustments. In contrast, the caudal SC, representing more peripheral visual field, is associated with the large gaze shifts (saccades). However, evidence regarding whether this functional gradient is preserved in the human SC remains limited. In this study, we employed a sequence-following visual-motor task to specifically …

The Confidence-Man Goes To The Moving Panorama: Herman Melville’S Confidence Narrator And United States Imperialism, Bradley J. Lee

Graduate Theses/Dissertations

This thesis argues that Herman Melville fashioned his novel The Confidence-Man; His Masquerade (1857) after the moving panorama, a popular entertainment technology contemporary with the novel. More specifically, the thesis argues that the novel recalls Banvard’s Mississippi Panorama (1846). Using Jay Leyda’s The Melville Log and John Hanners’ record of Banvard’s performances, I establish beyond reasonable doubt the possibility that Melville saw this painting, or, at the very least, was aware of it, its content, and its social position. Tracing the novel’s engagement with this panorama reveals what seems at first to be its imperialist, Manifest Destinarian undertones. The novel’s …

Thrombelastography As A Predictive Tool For Thromboembolic Events After Extremity Trauma: A Secondary Analysis Of Prevent-Clot, Cory K Mayfield, Nathan N O'Hara, Prism S Schneider, Renan C Castillo, Robert V O'Toole, Katherine P Frey, William Obremskey, Deborah M Stein, Reza Firoozabadi, Stephen J Warner, Madhav A Karunakar, Joshua L Gary

Faculty, Staff and Student Publications

Background: Venous thromboembolism (VTE) poses significant risk of morbidity and mortality in orthopaedic trauma patients. Thromboelastography (TEG) analysis has been demonstrated to provide value in demonstrating hypercoagulability and predicting the risk of post-injury VTE. The primary aim was to investigate if TEG analysis at the time of admission following severe extremity trauma predicts thromboembolic events. We hypothesized that previously described elevations in maximal amplitude (MA) on initial TEG would correlate with an increased risk of VTE.

Methods: This was a secondary study of PREVENT CLOT, a multicenter, randomized trial that enrolled adult patients with an extremity fracture (from hip to …

Risk Factors And Outcomes Of Reintubation Following Combined Heart-Lung Transplantation, Ye In Christopher Kwon, Michael Keller, Alan Lai, Brian Bao, Joshua Pei, Matthew Ambrosio, Jay Patel, Motaz Al-Yafi, Zachary Fitch, Josue Chery, Patricia Nicolato, Vigneshwar Kasirajan, Zubair A Hashmi

Faculty, Staff and Student Publications

Background: Unplanned reintubation after combined heart-lung transplantation (HLT) significantly affects morbidity and mortality, yet national data are limited. We evaluated the incidence, predictors, timing, and outcomes associated with reintubation after HLT.

Methods: We retrospectively reviewed adults undergoing primary HLT in the UNOS registry from January 2004 to September 2024. Patients were stratified by reintubation status (defined as re-established mechanical ventilation (MV) after initial extubation). Propensity matching (1:1) balanced recipient and donor characteristics. Multivariable logistic regression models identified independent risk factors.

Results: Among 609 adult HLT recipients, 165 (27.1%) required postoperative reintubation. After 1:1 propensity score matching, 146 patients who were …
