Bridging The Gap Between Counselor Education And Trauma Treatment In Practice: A Phenomenology Of Trauma-Specialized Counselors, Ariel Hutcheon

Counseling & Human Services Theses & Dissertations

Trauma impacts the life experiences of a sizable portion of the population. Given that so many clients bring trauma into counseling, even when not the presenting issue, knowledge of trauma’s impact and proficiency with trauma treatment are essential topics in counselor education. This study gave voice to counselors in the field to share what they have found effective from working with clients with trauma. The researcher used a phenomenological approach and interviewed six self-identified trauma-specialized counselors who have practiced for five years or longer. The data was explicated, and four major themes were identified. The first theme was Inadequate Training: …

Development Of A Handy Tool For The Selection Of Urban Stormwater Best Management Practices, Aaron T. Kenny

Civil & Environmental Engineering Theses & Dissertations

The City of Norfolk, Virginia faces substantial stormwater management challenges due to shallow groundwater, tidal influence, dense urban development, and limited right-of-way. These constraints limit the applicability of many Best Management Practices (BMPs) and require the early identification of feasible practices before detailed hydrologic modeling. This thesis introduces a decision-support tool that quickly and systematically identifies and prioritizes BMPs that are both feasible and well-suited to Norfolk’s Municipal Separate Storm Sewer System (MS4) program, streamlining early-stage selection and saving time and resources.

The tool implements a two-stage methodology. First, feasibility gates are applied using catalog attributes derived from the Virginia …

Two Essays On Customer Loyalty, Arjang Attar Shoushtari

Theses and Dissertations in Business Administration

Customer loyalty is vital for business success, yet most research treats loyal customers as a uniform group. This essay challenges that assumption by proposing that attitudinally loyal customers are psychologically heterogeneous. Drawing on Construal Level Theory (CLT), I introduce the construct of Consumer-Brand Construal Level (CBCL) to distinguish loyal customers based on how abstractly or concretely they construe their brand relationships. I conceptualize two loyalty mindsets, macro-loyalty (abstract, big-picture) and micro-loyalty (concrete, detail-focused), and argue that even highly loyal consumers differ meaningfully in their CBCL. I develop and validate a new CBCL scale (Studies 1–2) and then test how these …

A Systematic Review Of Corporate Ethics Program Training Strategies To Improve Ethical Workplace Cultures, Robin Raye Altice

Educational Leadership & Workforce Development Theses & Dissertations

The demand for corporations to practice more ethically responsible conduct and decision making is growing with every news report of another corporate scandal, lawsuit, fine, or high-visibility C-suite firing. To develop an ethical workplace culture, organizations should implement a comprehensive ethics program that fosters and encourages ethical decision making, especially among current and future leaders. However, there is little research and few guidelines for how ethics program administrators should design corporate ethics training to effectively practice and master the skill of ethical decision-making in efforts to continually grow a more ethical work environment. This study aims to identify corporate ethics …

Exploring Bonding Through Outdoor Recreation In Foster Care Utilizing Attachment Theory, Casandra L. Barnes

Communication & Theatre Arts Theses

As of 2024, there are over 328,000 children in foster care in the United States (AFCARS, 2024), many of whom experience disrupted attachments and trauma that hinder their ability to form healthy relationships. Drawing from attachment theory, this study explores how outdoor recreational activities can facilitate bonding between foster parents and their foster children. Using a mixed method approach this explorative research project consisted of two phases: a pilot study at the Virginia zoo involving foster families participating in a cooperative outdoor activity and completing post event surveys, and semi-structured interviews with foster parents to examine lived experiences of bonding …

Schema, Stigma, And The “We-Them” Divide: Perspectives On Ageism From Everyday Life To Healthcare, Temple D. West

English Theses & Dissertations

Ageism remains a pervasive and often underexamined form of discrimination, affecting older adults across both everyday and clinical contexts. This paper explores how cognitive schemas—mental frameworks that shape perception and experience—and stigma interact to reinforce a “we–them” divide between and older patients and healthcare providers, as well as between older and younger individuals in broader society. Through focus groups and listening to the voices of older patients, this study examines how assumptions of age-based decline are embedded in society and inform schemas of ageism. It considers how those schemas shape the spoiled identity of older people as a stigmatized group, …

Large Language Models (Llms) For Clinical Note Generation: International Classification Of Disease (Icd) Code, Knowledge Graph (Kg) And Prompt Evaluation, Ivan P. Makohon

Computer Science Theses & Dissertations

In the past decade, a surge in the amount of electronic health record (EHR) data in the United States occurred, driven by a favorable policy environment created by the Health Information Technology for Economic and Clinical Health (HITECH) Act of 2009 and the 21st Century Cures Act of 2016. Clinical notes for patients’ assessments, diagnoses, and treatments are captured in these EHRs in free-form text by physicians, who spend a considerable amount of time entering them. Manually writing these notes is time-consuming, increasing patient waiting times and potentially delaying diagnoses. Large language models (LLMs), such as GPT-4o, possess the ability …

On The Scalability Of Anisotropic Mesh Adaptation On Distributed And Shared Memory Architectures For Numerical Approximations, Kevin Mark Garner Jr.

Computer Science Theses & Dissertations

Mesh generation is a critical component in numerical approximations of Partial Differential Equations (PDEs). One such example includes Computational Fluid Dynamics (CFD), as CFD simulations in turn are crucial for applications in many industries, such as personalized healthcare and the design of aerospace vehicles. Generating high quality meshes for large-scale CFD problems presents a significant bottleneck in the CFD workflow. This dissertation proposes “fast,” parallel 3D mesh generation methodologies that are designed to leverage the concurrency offered by emerging High-Performance Computing (HPC) architectures. First, a distributed memory method is presented that integrates a sequential state-of-the-art isotropic, advancing front local reconnection-based …

Marginalized Pre-Service Teachers’ Digital Competence: An Exploration Of Epistemic Beliefs And Lived Experiences, Jerolyn Rose Brown

STEMPS Theses & Dissertations

Amid growing calls for equity in teacher education, this dissertation investigates how digital competence and epistemological beliefs interact within the lived experiences of marginalized pre-service teachers (mPSTs), also referenced as teacher candidates, whose racial and ethnic identities often position them at the periphery of dominant educational narratives. Anchored in critical narrative inquiry (Pino Gavidia & Adu, 2022) and framed by the DigCompEdu digital competence model (Redecker & Punie, 2017), the study employs a multimethod approach, integrating quantitative data from the SELFIEforTEACHERS self-assessment tool (Economou, 2023) with qualitative insights drawn from in-depth narrative interviews. The participant cohort consists of 50 marginalized …

Un-Tempering The Tempered Radical: A Phenomenological Study Of Black Female Superintendents In Neoliberal Education Systems, Melanie Fitzgerald Daniel

Educational Leadership & Workforce Development Theses & Dissertations

The persistent and severe underrepresentation of Black women in K-12 educational leadership (just 1.4% of superintendencies) is a critical manifestation of Epistemic Injustice (Fricker, 2007) and the Architecture of Hostility. Dominant managerial paradigms in education structurally suppress the voices and devalue the expertise of Black women, leading to both testimonial injustice (credibility deficits) and hermeneutical injustice (misinterpretation of experience). This context forces them to pursue advancement within systems fundamentally structured to exclude them. This phenomenological study utilizes a nested theoretical framework, comprising Neoliberalism (macro-context), Epistemic Injustice (meso-critique), and Tempered Radicalism (Meyerson & Scully, 1995; Ngunjiri, 2012) (micro-agency), to illuminate the …

In this dissertation, titled “A Voice to Remember: Recovering the Rhetoric of Mordecai Wyatt Johnson,” I perform and analyze the rhetoric associated with him. Johnson was well known for being the president of Howard University; the goal of this project is to recover the rhetoric and identify the common themes. The two themes identified in Johnson’s rhetoric are religion and education. Personal traits and associations with religion are traced …

Understanding Executive Order 13583’S Impact To Federal Workforce Diversity & Employee Perception Of Federal Policies And Programs, Michael Robert Arenella

School of Public Service Theses & Dissertations

Creating a more diverse, equitable, and inclusive (DE&I) workforce produces beneficial organizational outcomes, such as decreased turnover, improved creativity and innovation, and improved organizational performance (Diaz-Garcia et al., 2013; Gomez & Bernet, 2019; McLeod et al., 1996; Singh & Selvarjan, 2013). While the private sector has placed much emphasis on improving DE&I in their hiring practices, whether the federal government has achieved comparable outcomes remains unclear. Guided by the punctuated equilibrium theory (PET), this dissertation examines the impact of Executive Order 13583 on both change in workforce composition, and employee sentiment towards diversity policies and programs.

Using a multi-level, multi-method, …

Violence As An Ecology: Women Making Safety In Khayelitsha, Melissa J. Miller-Felton

Graduate Program in International Studies Theses & Dissertations

This dissertation asks how women in Khayelitsha make safety in a place where danger has become ordinary and where the afterlives of colonialism and apartheid still determine who waits, who walks, and who arrives home. What began as a study of risk and protection grew into an inquiry about time, dignity, and responsibility. I call the framework that emerged an ecology of violence—a way of seeing how harm gathers across generations and infrastructures, and how care, exhaustion, and survival intertwine within it.

In this ecology, violence is not a single act but a confluence of registers—slow, structural, colonial, and …

Taming The Wicked Problem: Transparency, Civic Apathy, And The Challenge Of Rebuilding Trust In Local Government, Austin N. Kaiser

School of Public Service Theses & Dissertations

Since the 1960s, the United States has experienced a persistent decline in public trust in government. The Founders believed that government could only function with the consent of the governed, making this erosion of trust a significant concern for democratic legitimacy. In response, many scholars and practitioners have championed transparency as a pillar of sound governance and a potential remedy for rebuilding trust. However, the solution may not be as simple as improving openness. Public officials increasingly recognize that transparency alone may have limited or even unintended consequences, especially when public participation is low or administrative resources are strained.

This …

Evaluation Of Ocean Lidar Enhancement Through Miniaturization And Gated Pmt-Based Range Extension, Chandler Austin Slater

OES Theses and Dissertations

Oceanographic lidar systems remotely characterize the vertical structure of the upper ocean by recording the light backscattered from a laser pulse as it propagates through the water column. Historically these systems have been constrained by limited detection ranges, often capturing only a portion of the illuminated water column, typically fading to noise around the 10% isolume. A primary constraint has been the limited dynamic range of digitizers, which inhibits the ability to resolve both intense near-field and faint far-field backscatter signals within a single acquisition. To address this, we developed a novel optical lidar system incorporating gated photomultiplier tubes (PMTs) …

Aluminum As A Tracer Of Dust Deposition To The Ocean: A Case Study From The Bermuda Region, Tara Elizabeth Williams

OES Theses and Dissertations

Aluminum (Al), a major component of mineral aerosol (dust), partially dissolves in seawater and is widely used as a tracer for estimating time‐averaged dust fluxes to the ocean. Such estimates rely on dissolved Al (DAl) inventories in the surface mixed layer (SML), an assumed SML residence time of DAl (_TDAl), the fractional solubility of Al in dust (Al_S), and the mass fraction of Al in dust. In this study, dust flux estimated from seasonal, water-column DAl data from the Bermuda Atlantic Time-series Study (BATS) region are compared with direct dust flux estimated from contemporaneous measurements of …

Observed Parenting, Parent-Child Aggression, And Intimate Partner Violence As Predictive Of Family Dysfunction, Paige Munshell

Psychology Theses & Dissertations

Family systems theories contextualize violence as occurring across multiple levels of the family, yet much of the existing literature focuses on a single family member’s outcome (i.e., the child) and neglects to include data collected from fathers. This study examined the associations between indicators of functioning at the dyadic-level in the family system—observed parenting, Intimate Partner Violence (IPV) perpetration, and Parent-Child Aggression (PCA) risk—and later overall family dysfunction. Participants were 180 mothers and 144 of their male partners evaluated when their child was 18 months old and re-evaluated at 4 years old. Measures of observed parenting, IPV perpetration, and PCA …

Identifying Alcohol Intervention-Relevant Constructs For Greek Life: Examining Across Greek Membership And Gender Among College Students, Emily Susan Renzoni

Psychology Theses & Dissertations

Among college populations, students who are members of social Greek life organizations (i.e., social fraternities and sororities) drink more and experience higher rates of negative alcohol-related consequences than their non-affiliated peers. Although there has been success of alcohol interventions in general college populations, research has shown that college drinking interventions that are delivered to students in Greek life are not efficacious in reducing alcohol consumption or related consequences. It is meaningful to investigate if the content commonly addressed in these interventions, although well-documented as being linked to drinking in the general college population, has the same associations for students who …

Machine Learning For Anomaly Detection In Neural Network Security And Srf Cavities, Hal Ferguson

Electrical & Computer Engineering Theses & Dissertations

Anomaly detection identifies deviations from expected patterns, safeguarding systems in cybersecurity, industry, and research against malicious activities and failures. This dissertation demonstrates how our machine learning approaches enhance detection accuracy and efficiency in both neural network security and industrial applications.

First, we investigate vulnerabilities in deep neural networks deployed in federated learning. Although federated learning preserves …

Identity Salience Of Organizational Culture: The Intersection Of Racial And Occupational Identities In High-Risk Professions, Sarah Espinosa

School of Public Service Theses & Dissertations

Despite decades of effort, issues of race and color in organizations remain unresolved. Representative Bureaucracy (RB) has been a necessary but insufficient response to these challenges. While RB promotes diversity and inclusion, it struggles to address deeper issues of equity and justice, which are seen in the persistence of police brutality, even with increased representation of officers of color. This dissertation will propose a new theoretical approach to address the shortcomings of RB, a framework for the Identity Salience of Organizational Culture (ISOC). The ISOC framework seeks to build beyond RB to explain how the culture of high-risk professions with …

The Presentation Of Self In Everyday Digital Life: A Study Of Self- Disclosure And Work Environments, Mackenzie Michelle Skiff

Communication & Theatre Arts Theses

The digital age impacts individuals’ lives in many ways. One impact is how and where work is completed across many careers. The work-from-home strategy enables individuals to complete work that is not within a shared space, such as an office. With the absence of this shared space, communication practices within workplaces could be changing. Specifically, self-disclosure while working from home may differ from self-disclosure within the office or hybrid (both in office and remote) work environments. This thesis investigates whether there are differences in self-disclosure practices across three different types of contemporary work environments and offers a digital update to …

Reflections In The Mirror: An Examination Of Racially Congruent Mentoring Of Black Teacher Candidates In A Teacher Education Program, Mary Louise Gregory

Teaching & Learning Theses & Dissertations

The high demand for Black educators in K-12 schools across the United States has caused several teacher training programs to rethink how they prepare Black teacher candidates for the teaching workforce (Andrews et al., 2019; Blazar, 2024; Milner & Howard, 2004). Improving teacher candidate training, especially for Black teacher candidates can boost K-12 Black teacher representation. Literature on Black teacher candidate’s experiences while being mentored identifies several challenges that include issues with implicit bias, microaggressions, stereotyping and other occurrences of racial discrimination (Daly et al., 2024; Hampton et al., 2008; Kardos & Johnson-Moore, 2010; Rodriguez et al., 2020). The process …

Making Explanations Make Sense: Xai For Smishing Detection, Eleni Alexandra Katsarakes

Psychology Theses & Dissertations

Explainable Artificial Intelligence (XAI) is a key component of effective human-AI collaboration, particularly in high-stakes domains such as cybersecurity. While AI tools hold promise for mitigating threats such as SMS-based phishing (SMiShing), their real-world effectiveness may hinge not just on detection accuracy, but on whether users can make sense of the system’s outputs. As SMiShing attacks grow in both frequency and sophistication, so does the urgency of designing human-centered AI systems that support user decision-making under uncertainty. This study examined how four distinct AI explanation types - Normative (rule-based), Attributive (feature-based), Exemplar (case-based), and Recommendation-Only - influence user performance, confidence, …

Reading The Romance Reader: Booktok, Algorithmic Subjugation, And The Fight For Cultural Legitimacy, Emily Maranto Hill

Communication & Theatre Arts Theses

This thesis examines the transformation of romance reader identity through the lens of BookTok, investigating how digital platforms grant cultural legitimacy while simultaneously subjugating community practices to algorithmic control. Romance readers historically developed emotional labor practices, counter-public formation strategies, and fan-driven meaning-making to resist decades of cultural marginalization. Through analysis of TikTok's platform attributes, user behaviors, and the viral Tillie Cole controversy, this study traces how BookTok converts these resistant practices into behavioral data optimized for engagement rather than authentic discourse. The research employs theoretical frameworks including Janice Radway's ethnographic analysis, Shoshana Zuboff's surveillance capitalism, Nick Srnicek's platform capitalism, and …

This study explores the correlation between organizational structure and social justice reform in American public schools. The study specifically aims to answer the following research questions: What are the lived experiences of school leaders as they navigate and enact social justice reform? How do school leaders experience the ways organizational structures shape their opportunities and challenges in implementing social justice reform? How do school leaders experience and make sense of the influence of local, state, and national policy on their efforts toward social justice reform in American public schools? The literature review examined organizational structure through the lens of Ecological …

Leading With All The Feels: Exploring The Perceptions Of Middle School Administrators' Implementation Of School-Wide Social-Emotional Learning Programming, Sabrina Smith Richardson

Teaching & Learning Theses & Dissertations

Middle school administrators have multiple responsibilities that range from ensuring the safety and security of staff and students to overseeing the curriculum and instructional foci of their buildings. At the same time, middle school students are experiencing the early stages of adolescence. Because it is a complex time for students to navigate, it creates anxiety, a decline in academic achievement and motivation, and peer and academic pressures (London, 2022; Schlund, 2021). Middle school students have social-emotional needs that are not typically met in secondary schools, which means programming is not typically a part of the instructional day. This study examined …

Proactive Onboarding Services Model As An Academic And Social Integration Strategy For First-Time In College Students At A Virginia Community College, Jhansi V. Eturu

Educational Leadership & Workforce Development Theses & Dissertations

A recent survey by the Education Advisory Board (EAB) found that of the 1000 community college students surveyed, 56% nearly quit before classes started due to challenges during college onboarding. Similarly, admissions data from the Virginia Community Colleges System (VCCS) indicated that more than half of the students who apply do not enroll in classes, highlighting a need to closely examine the onboarding process and support services provided to understand what is effective and what is not. The purpose of this study is to understand the predictive utility of certain student onboarding services, such as an appointment with an admissions …

Examining Social And Intrapersonal Factors Among Youth Crisis Line Volunteers, Sunday Hull

Psychology Theses & Dissertations

Crisis lines provide a free crisis response service that is highly accessible to individuals who are at elevated risk of suicide and may not be otherwise connected with care. In order to best tailor crisis line interventions to youth populations, a number of youth-to-youth crisis lines invite youth callers to connect with trained youth volunteers. While prior research has examined adult crisis lines workers’ experience and well-being and identified key factors that predict positive and negative volunteering outcomes, far less is known about similar determinants of experience and well-being among adolescent volunteers on youth-to-youth crisis lines. The purpose of this …

Comparative Analysis Of Emergent Behaviors Of Three Drone Swarm System Models For Targeting Using Agent-Based Modeling And Simulation, Arsenio T. Gumahad Ii

Engineering Management & Systems Engineering Theses & Dissertations

This dissertation introduces a novel computational simulation framework for evaluating the emergent behaviors of three swarm drone models using Agent-Based Modeling and Simulation (ABMS). The three swarm models are a Leader-Follower swarm model based on Bruckstein's antline theory, a Flocking model based on a simplified Reynolds 'Boids’ model, and a Stigmergic model with pheromone-based coordination. The primary objective of the simulation is to evaluate the performance of these models in delivering a user-defined number of drones of each type to a target area of interest in four separate scenarios, resulting in 50,000 separate simulation trials. Each scenario was structured to …
