Developing Nursing Education On The Assessment Of Asthma Patients With Symptoms Of Shortness Of Breath In Urgent Care, Abigail Akorfa Adase

Walden Dissertations and Doctoral Studies

This quality improvement project aimed to enhance the assessment of dyspnea in patients presenting with shortness of breath, particularly those with asthma, through a staff education program. At the practice site, staff primarily relied on SpO₂ readings to evaluate dyspnea, which often led to misassessment and delays in care. The project addressed this gap by providing urgent care staff with training on comprehensive assessment techniques, including evaluation of respiratory rate, work of breathing, ability to speak, patient history, and use of validated tools such as Borg’s scale and peak flow meters. Twenty triage staff members participated, including licensed practical nurses, …

Effective Leadership Strategies For Character Education, Kim Fricke Bilanko

Dissertations

Although character education has been widely studied, limited research has examined the specific leadership strategies building administrators use to implement and sustain comprehensive character initiatives. This qualitative study investigated the leadership practices of building administrators whose schools were designated as National Schools of Character (NSOC) in order to better understand how character education is institutionalized and maintained over time. Guided by an exemplar model and informed by constructivist grounded theory methods, the qualitative study explored (a) the leadership strategies administrators identified as essential to implementation and (b) the challenges they encountered, and the responses used to address them.

The Heart Of Leadership: How Urban High School Principals Enact Integrated, Equity-Centered Leadership, Alisha N. Coleman-Kiner

Electronic Theses and Dissertations Archive

Urban high schools serving historically under-resourced communities continue to experience persistent inequities in academic outcomes, student belonging, and school culture despite decades of reform. Leadership scholarship has identified several domains relevant to addressing these inequities, including instructional leadership, relational trust, care ethics, cultural responsiveness, trauma-responsive practice, and equity-centered decision-making. However, these domains are most often studied in isolation. As a result, the field lacks a coherent explanation of how these leadership practices interact in everyday school leadership and why schools operating under similar conditions often produce markedly different outcomes. The purpose of this qualitative multiple-case study was to examine how …

Targeting Mitochondrial Fitness To Restore Immune Balance In Aging: The Role Of Urolithin A, Rafael Moura Maurmann

Electronic Theses and Dissertations Archive

Aging drives systemic functional decline and represents the primary risk factor for comorbidities and mortality. Immune dysregulation is central to chronic age-related inflammation, with macrophages acting as key mediators of unresolved tissue damage. This functional compromise coincides with metabolic maladaptations including elevated mitochondrial stress and impaired mitophagy, which exacerbate oxidative stress and inflammatory overstimulation. However, the exact mechanistic links driving these phenotypes remain incompletely understood. Urolithin A (UA) has emerged as a promising strategy to enhance mitochondrial health via mitophagy stimulation, yet its immunoregulatory effects in the context of aging remain unexplored. Objectives: This study aimed to characterize mitochondrial dysfunction …

Organismic Encoding Of Geographic Information In Dna, Hema Siva Gayathri Dalavayi

Electronic Theses and Dissertations Archive

Recent evidence suggests that DNA also encodes information that reflects long-term environmental conditions. This work examines whether an organism’s genome encodes specific environmental information, and if so, what is its nature and origin. Genes from three insect groups, Simuliidae (blackflies), Lepidoptera (butterflies), and Formicidae (ants), were analyzed to address the geographic provenance (latitude, longitude) problem. DNA was converted into numerical signatures using noncrosshybridizing DNA bases and used to train machine learning (ML) models. Predictions achieved errors below the baseline, even for models trained on combined data without region-specific labels, indicating that DNA encodes this information and suggesting that the underlying …

Investigation Of Target Detection In Hyperspectral Images For Aided Target Recognition, Mazharul Hossain

Electronic Theses and Dissertations Archive

Aided/Automatic Target Recognition (AiTR/ATR) enhances human decision-making by improving the detection, localization, and interpretation of targets in sensor imagery. Hyperspectral (HS) imaging provides rich spectral information for AiTR that can significantly improve target detection; however, HS detectors often perform unreliably in real-world conditions due to high data dimensionality, limited labeled training data, class imbalance, sensitivity to environmental and sensor variations, and a shortage of pre-trained models. These challenges frequently lead to degraded performance when models trained in one setting are deployed in different scenes, sensors, or operating conditions. The overarching goal of this dissertation is to make hyperspectral target detection …

Advancing Multimodal Distracted Driving Detection: From Systematic Synthesis To Representation Alignment In A Unified Embedding Space, Anthony Dontoh

Electronic Theses and Dissertations Archive

Distracted driving remains a critical road safety challenge, as existing detection methods often rely on single-modality inputs that lack the contextual nuance to distinguish hazardous behavior from normal driving. This research program addresses these limitations through a progressive three-study framework that advances context-aware detection from systematic evidence synthesis to multimodal foundation model adaptation, reframing detection as a representational alignment problem. Study One systematically reviewed 77 peer-reviewed papers (2019–2025) across visual, sensor-based, and emerging modalities. The results confirmed a dominance of visual-only approaches and identified critical gaps in environmental robustness, cognitive distraction detection, and contextual grounding, establishing the empirical necessity for …

Unveiling The Intersection Of Institutional Racial Identity And Student Loan Debt: An Analysis Of The State University System Of Florida’S Higher Education Institutions, Valerie Marie Moore

USF Tampa Graduate Theses and Dissertations

Federal student loan patterns in Florida’s State University System (SUS) from 2013/14 to 2022/23 reflect differences in institutional revenue capacity rather than individual borrowing behavior. Using data from all 12 SUS institutions, this study examined how institutional wealth and revenue composition shape student loan outcomes through both race neutral and race considerate analyses informed by Ray’s (2019) theory of racialized organizations. Overall, the SUS operates as a racialized organizational field in which inequities in funding flows, access to capital, and institutional logics sustain long term disparities in wealth and debt.

Bringing Worlds Together: How Social Studies Teachers Make Content Meaningful, Harley A. Payne

Honors College Theses

Secondary educators in social studies classes face the challenge of maintaining the attention of dozens of students during instruction, often on content that seems irrelevant or unimportant. Educators must find ways to emphasize that the content their students are disinterested in is useful and crucial for their development into adults. Research suggests that bridging the gap between the classroom and the real world improves classroom engagement (Cooper, 2014; Tagliaferro, 2012). Students who are engaged and exert more effort in class derive academic benefits, such as placement in advanced pathways and increased test scores (Carbonaro, 2005). Civics education and the inclusion …
