Heart failure is a leading cause of morbidity and hospital readmissions, with limited health literacy contributing to poor self‑management and adherence challenges. The purpose of this Doctor of Nursing Practice project was to evaluate the feasibility and preliminary outcomes of a nurse‑led, virtual education-intervention designed to improve health literacy, self‑care behaviors, and medication adherence among adults with chronic heart failure who participate in an outpatient support group. A quality improvement design was used. Convenience sampling yielded nine adult participants with a documented diagnosis of chronic heart failure who attended at least one virtual support group session. The intervention consisted of …

Whiny Women: How Medical Gaslighting Becomes Medical Trauma, Neena Marcus

Honors Projects

Background: The idea of “medical gaslighting” has been present since 1969, but it has increased in popularity in the recent century. Women in particular are at increased risk of being dismissed by their healthcare providers, as throughout history they have been deemed “hysterical” or untrustworthy when recounting their symptoms.

Methods: Articles were compiled from CINAHL Complete, Google Scholar, and the University of Washington library. A total of 33 articles were chosen and reviewed.

Results: Medical gaslighting results in lasting medical trauma, a decreased quality of life and detachment from standard healthcare. Six themes were recurrent in the papers utilized: sexism, …

Perception, Payment, And Pollution- Examining The Effects Of Air Quality On Health And Healthcare, Colin Sleeper

Economics ETDs

Abstract

This dissertation examines how air quality and public attention to environmental shock affect perceived health status and healthcare utilization. The first chapter uses publicly available survey data from BRFSS and a triple difference framework to analyze the effects of the 2018 wildfire season in Oregon on self-reported mental and physical health. Findings indicate that those in Oregon in 2018, during the period of heightened attention to wildfire smoke, experienced approximately 1.4 additional poor mental health days, on average. The second chapter includes Merative MarketScan commercial insurance claims data to test whether these changes translate into a behavioral response. Results …

Agricultural Water Management, Farmer Decision-Making And Climate Adaptation In Dryland Agriculture: A Case Of The Middle Rio Grande Basin, Oluwatosin A. Olofinsao

Economics ETDs

Agriculture in dryland regions faces mounting pressure from climate change, water scarcity, and shifting land-use demands. The Middle Rio Grande Basin (MRGB) of central New Mexico exemplifies these challenges, where irrigated agriculture relies on increasingly variable surface water supplies. This dissertation examines agricultural water use, farmer decision-making, and adaptation strategies across farm types and climate conditions in the MRGB. The first study presents a spatial descriptive analysis of farm size, crop patterns, groundwater access, evapotranspiration (ET), and effective ET, revealing a landscape numerically dominated by smallholder farms that account for a substantial share of irrigation water use. The second study …

Marine Geophysical Studies Of Coupled Tectonic And Sedimentary Processes At Active Plate Boundaries, Sarah R. Rysanek

Earth and Planetary Sciences ETDs

Deep-sea and convergent margin sedimentary systems preserve critical records of tectonic and climatic processes that shape Earth’s surface. This dissertation investigates source-to-sink sediment routing and forearc deformation to better constrain the interplay between sedimentary and tectonic processes, through investigations of a deep-sea fan system, and the forearc geomorphology offshore Nicaragua. In the Gulf of Alaska, we integrate ultra-long-offset and regional multi-channel seismic reflection data, multi-resolution bathymetry, and plate reconstructions to remap the Baranof Fan system. Results show that the fan is larger than previously recognized and constructed by two primary depocenters linked to distinct glacial sediment pathways, with accommodation space …

Constraining Magmatic Processes In The Central American Arc Using Melt Inclusion Vapor Bubble Analysis And Triple Oxygen Isotope Modeling And Exploration Of Volatile Contributions To The Production Of Continual Radio Frequency (Crf) Lightning Events, John M. Hamilton

Earth and Planetary Sciences ETDs

Magmatic volatiles are key to determining the processes happening in the subsurface that we cannot directly sample. Advances in measuring volatile and isotope contents from erupted volcanic samples have given us the ability to understand magmatic processes, mixing components that produce the bulk magma composition and potentially precursors to eruptive hazards, such as lightning.

Through analysis of melt inclusions that sample the melt at depth and triple oxygen isotope quantification of olivine crystals from multiple volcanic edifices, the three following studies display how I have utilized these analytical techniques to help unravel processes happening in the subsurface that lead volcanic …

Impact Of Third Trimester Alcohol Exposure (Ttae) On Oligodendrocyte Development And Behavior In Mice, Estrella Villicana

Biomedical Sciences ETDs

Prenatal alcohol exposure (PAE) during late gestation can cause cognitive, behavioral, and motor impairments associated with fetal alcohol spectrum disorders (FASDs). The third trimester corresponds to a critical period of brain growth and maturation. This study examined the effects of Third Trimester-equivalent Alcohol Exposure (TTAE) on oligodendrocyte development and adult behavior. Neonatal mice were exposed to ethanol or air vapor from postnatal day (P) 4–8. Immunohistochemical analyses were performed at P8 and P30 to assess myelination, apoptosis, and oligodendrocyte lineage progression. TTAE significantly reduced myelin basic protein (MBP) expression at P8, which was recovered by P30, indicating delayed developmental myelination. …

Design And Optimization Of Epitope Based Malaria Vaccine Targeting Pre-Erythrocytic Stage, Yogesh Nepal

Biomedical Sciences ETDs

Malaria remains a major global health challenge. Currently available vaccines provide only modest and transient protection. In this work, we developed virus like particles (VLPs) based vaccine to target vulnerable epitopes of circumsporozoite protein, a key surface protein of pre-erythrocytic sporozoite stage, across different structural contexts. The immunogenicity of these highly immunogenic vaccines were further enhanced using immune stimulating agents, adjuvants, and the most promising VLP and adjuvant combinations were evaluated in preclinical challenge models to assess efficacy. In parallel, we performed research in an antigen agonistic manner using VLP library immunization that displays different fragments of a target protein …

Exploring Color-Blind Racial Attitudes And Critical Race Theory - Informed Beliefs Among School Social Workers, Faith E. King

Social Work Doctoral Dissertations

Black Americans face unequal rates of psychological distress and misdiagnosis primarily due to systemic racism embedded in institutions. Despite these alarming realities, current mental health frameworks often cling to biased perceptions of wellness facilitated by White, Eurocentric norms that pathologize communal resilience and cultural expressions of healing. In clinical spaces, these realities are too often erased by the biased meanings and individualistic norms that render Black grief pathological and Black resistance dysfunctional. Dominant therapeutic modalities labeled “evidence-based” remain rooted in racially neutral, individualist assumptions that exclude the lived experiences of Black clients, as they were developed for them. The National …

Moving As Mycelium: Dance/Movement Therapy With Nature And Its Potential For Sustainability Transformations: A Literature Review, Abby Polk

Expressive Therapies Theses

Environmental degradation and destruction impact the long-term health and wellbeing of humans and ecosystems alike. Humans require new ways of relating to nature that support sustainable futures for all. This thesis argues that dance/movement therapy (DMT) with nature has the potential to facilitate sustainability transformations and that the embodiment of relationality can support the development of reciprocal human-nature relationships. This literature review is grounded in theories of relationality and reciprocity as conceptualized in various Indigenous knowledge systems and the fields of both sustainability and DMT. Existing research suggests that culturally-responsive, embodied, arts-based practices may increase human-nature connectedness and strengthen reciprocity …

Post-Fire Flood Modeling In Ruidoso, New Mexico: Improving Burn Scar Runoff Predictions, Pramesh Bhaila

Civil Engineering ETDs

Recent large wildfires in New Mexico have demonstrated severe hydrological driven by vegetation loss and the development of hydrophobic soil surfaces. This thesis evaluates the performance of three infiltration models—Curve Number (CN), Linear Constant (LC), and Green–Ampt (GA)— for the watershed impacted by the 2024 South Fork and Salt Fires near Ruidoso, New Mexico. All three models performed comparably during post‑fire simulations, with strong performance in 2024 and notable degradation in 2025, particularly for the CN. Post-fire analyses indicate substantial reductions in infiltration capacity, with CN increasing by 18–24%, LC initial deficit decreasing by 65–77%, effective hydraulic conductivity reduced by …

Identification Of Aortic Centerline Shape Features, Bebel B. Trani

Mechanical Engineering and Materials Science Independent Study

Better predictions of the likelihood of an aortic event in patients are paramount to providing quality care in medicine. Ascending aortic aneurysms (AsAA) are typically asymptomatic until sudden complications, such as rupture or dissection, occur and are often fatal [1]. As a form of preventative care, physicians identify and monitor high-risk patients. Surgical interventions are also performed for high-risk patients, replacing the weakened segment of the ascending aorta before a catastrophic event occurs. Determining which patients require surgical intervention or close monitoring is therefore extremely important. These decisions are largely guided by maximum diameter measurements; for the ascending aorta, a …

Education Dissertations

Early and Middle College High Schools (EMCHS) expand college access for

underrepresented students by integrating high school and college coursework within

community college settings. Despite strong reported outcomes, some EMCHS face

substantial student attrition. Limited research examines how EMCHS organizational

structures influence student persistence. This mixed methods outcome and process

evaluation seeks to address this research gap. Quantitative analysis (paired samples-t-

tests) examined statewide enrollment data (2017-2025) to determine whether significant

differences exist between Year 1 and Year 4 cohort enrollment. Qualitative analysis was

conducted through a deductive discourse analysis of Western Association of Schools and

Colleges (WASC) Self-Study reports …

Evaluation Of Intracavity Electromagnetic Field Probes And Sources: Implications For Shielding Effectiveness, Joseph Anthony Ferreri

Electrical and Computer Engineering ETDs

To measure the electric field in a reverberant cavity, a small, minimally invasive probe is required. Common solutions include electrically small surface mounted monopole antennas, B-dots, and D-dots. To obtain an accurate field measurement with a particular probe, it is necessary to characterize it to compensate for its ability to convert electric field into voltage which requires a gauge factor known as effective height. The characterization process is straight forward in open space on a ground plane but requires more insight when in situ in a reverberant cavity. This work adapts ground plane probe characterization methods for cavity measurements, facilitating …

Alternative Positioning, Navigation, And Timing In Global Navigation Satellite System Denied Environments, Joshua R. Atencio

Electrical and Computer Engineering ETDs

Global Navigation Satellite Systems (GNSS) provide the majority of critical positioning, navigation, and timing (PNT) services for civilian, commercial, and military applications. However, GNSS is vulnerable to service denial from spoofing and jamming from adversaries and environmental obstruction. These vulnerabilities highlight the need for resilient Alternative PNT (APNT) methods. This dissertation investigates APNT frameworks operating in GNSS denied environments. We develop coalition formation and matching theoretic models that allow users APNT services from anchor nodes under resource constraints and in adversarial or emergency conditions. The proposed frameworks optimize positioning accuracy, network utility, and system stability while accounting for geometric dilution …

Calibration Methodology, Diagnostic Performance, And Redesign Of The Current Monitors On The Z Machine At Sandia National Laboratories, Stacie Hernandez

Electrical and Computer Engineering ETDs

A proper evaluation of the current diagnostics fielded in the inner-MITL region of the Z facility in 3D simulation models had not been performed until now. The evaluation of the current monitors has brought insight to their performance in a new view that has led to discoveries. The B-dot probe was the current diagnostic-of-choice since before the refurbishment of the Z facility [1] and until the development of the Inductively Driven Transmission Line (IDTL) current diagnostic [2]. Experimental data has shown that the IDTL can produce cleaner signals and it is more robust than conventional B-dots. Simulation (modeled using COMSOL …

Applications And Comparisons Of Machine Learning Methods In Ultra-Fast Laser Control, Aasma Aslam

Electrical and Computer Engineering ETDs

This dissertation demonstrates the applications and comparative analyses of machine learning methods in ultrafast laser control. By learning the relationship between the system’s input parameters and output pulse characteristics, the performance of a laser can be significantly improved. In this work, the results are presented in two stages by utilizing data from the femtosecond laser system. The first stage concerns two neural networks, named NN1 (fitrnet) and NN2 (feedforwardnet). The second stage, which extended with five different models, namely the linear regression (fitlm), the support vector machine (SVM), the Gaussian process regression (GPR), the boosted tree (fitrensemble), and LASSO (fitrlinear), …

Stochastic Derivative-Free Deep Learning Methods For Solving High Dimensional Partial Differential Equations, Qing He Mr.

Mathematics Theses and Dissertations

Solving high-dimensional partial differential equations (PDEs) is a fundamental challenge in scientific computing, with applications ranging from quantum chemistry and computational finance to statistical physics and stochastic optimal control.  Classical numerical methods such as finite element or finite difference schemes suffer from the curse of dimensionality, rendering them computationally infeasible when the dimension $d$ exceeds a handful. Physics-informed neural network (PINN) methods alleviate this by embedding the PDE residual directly into a loss function, but they require computing derivatives of the network with respect to its spatial inputs---an operation that scales poorly in high dimensions and demands that the approximate …

The Drive Diaries: How Motivation Shapes Work And Performance, Christian D. Diaz

Masters Theses, 2020-current

Employee motivation remains central to organizational research, yet less is known about how employees personally experience the relationship between intrinsic and extrinsic motivation and performance. Grounded in Self-Determination Theory and Expectancy Theory, this qualitative narrative inquiry examined how employees describe their motivational experiences and their influence on workplace effectiveness. Semi-structured interviews were conducted with 3 employees across diverse industries and analyzed using thematic analysis.

Four themes emerged: (1) autonomy as a primary driver of sustained performance, (2) recognition as a reinforcing factor, (3) organizational culture as either amplifying or diminishing motivation, and (4) motivation as evolving across career stages. Findings …

The Motivation Tapes: Employee Narratives Of Leadership That Matters, Jessica Gray

Masters Theses, 2020-current

This qualitative phenomenological study explored how employees describe their lived experiences at work. The purpose of the research was to understand the relational, emotional, and developmental dimensions that shape employees’ day-to-day workplace realities and the meanings they assign to those experiences. Four participants from diverse occupational backgrounds were interviewed using semi-structured protocols designed to elicit rich, descriptive accounts of their work environments, relationships, and sense-making processes. The findings reveal that participants shared experiences of supportive and hands-on leadership, opportunities for autonomy and ownership, and moments of connection, meaning, and long-term growth. Participants also described disruptions to these experiences. The implications …

Lowering Class Size To Improve Teaching And Learning Mathematics In Early Grades, Dianne S. Mccarthy

Journal of Inquiry and Action in Education

Fourth-grade mathematics proficiency in the United States remains low, with only 39–57% of students meeting proficiency standards on NAEP, New York State, and TIMSS assessments. This article argues that reducing class sizes in the early grades (K–3) is an effective strategy to improve teaching and learning in mathematics. Evidence from the Tennessee STAR study and supporting research (Clanet, 2010; Cho et al., 2012) shows that smaller classes yield statistically significant and lasting gains in student achievement. Benefits include stronger teacher-student relationships, increased individualized attention, fewer disruptions, and more active student engagement. These conditions enable high-impact, constructivist approaches such as inquiry-based …
