Examining Explicit Professional Development As A Means To Change Inclusive Mindsets, Mitchell E. Elatkin

Theses and Dissertations

Inclusive education requires educators to hold beliefs that support the participation and success of students with disabilities in general education settings. Although federal policy mandates access to the least restrictive environment, educator attitudes toward inclusion continue to influence the implementation of inclusive practices. The purpose of this mixed-methods study was to examine whether explicit professional development (PD) focused on inclusive mindsets influenced school stakeholders’ attitudes toward inclusion across a school year. Participants included representatives from various roles within a charter school organization in the Midwest. The researcher collected data through two administrations of the Adapted Teacher Attitudes Toward Inclusion Survey …

Dining Experiences Across Hearing Profiles: The Influence Of Noise And Environmental Factors In Restaurants, Lorin M. Kmieciak

Dining out is a popular activity worldwide that is rooted in sensory and emotional engagement. How an individual experiences the sensory conditions in restaurants varies widely, highlighting the importance of designing dining environments that accommodate diverse perceptual needs and abilities. The purpose of this study is to address how existing dining environments overlook inclusive and accessibility-centered design by examining how hearing loss intersects with the acoustic, sensory, and social dimensions of dining environments. This study employed a mixed method, exploratory approach by gathering quantitative data through a survey and qualitative data through follow-up interviews to generate a holistic and data-driven …

"I Didn't Teach It Again Because It Wasn't Worth It": How Grades 6-12 English Language Arts Teachers Select Texts And Navigate The Obstacles That Impede Them, Steve Poggendorf

Theses and Dissertations

Classroom texts not only function as tools through which teachers can build curricula, but they can also engage and empower learners. Despite the importance of engaging texts in the classroom, teachers encounter obstacles, both social and institutional, that impede their ability to select the texts they believe will best foster student engagement and empowerment. The purpose of this qualitative study was to investigate how teachers make text selections, as well as the nature of the obstacles that stand in the way of teachers who hope to inspire and engage their students through lessons built around texts of their choosing. The …

Assessing Decision Making Of United States Arboreta: A Survey Of The Main Drivers Behind New Planting Selections, Sophia Reavley

Theses and Dissertations

When an arboretum needs to replace fallen specimens, what are they looking for in the new plant that will be added to the collection? Arboreta are locations where trees and shrubs can be studied in an area where the public can also enjoy them. This study looks to see what aspects of scientific value (conservation status, diversification, ornamental value, etc.) and what external factors (budgets, public opinion, research articles, etc.) of new species selections become the main driver in decision making. An anonymous online survey was used to collect data from arboreta and botanical gardens of the United States that …

This thesis focuses on college level and aged students who are the most likely demographic for beginning stage combat students. The completion of this thesis does not represent an endpoint in …

Development Of A Practical Lu-177 Activity Calibration Protocol For Clinical Nuclear Medicine: Dosimetric Impact Analysis And Implementation Tools, Azam Almolaiki

Theses and Dissertations

Lutetium-177 (Lu-177) is widely used in radionuclide therapy, where accurate activity measurement prior to administration is essential for safe and effective treatment delivery. However, variability in dose calibrator response due to measurement conditions and source geometry remains a practical challenge in routine clinical settings. This study presents a practical clinical calibration strategy under real-world constraints for Lu-177 activity measurement using standard nuclear medicine instrumentation. A vial-based approach was implemented using a well-type ionization chamber (Capintec CRC-15R) to evaluate measurement repeatability, temporal stability, and geometry dependence. All measurements were performed under consistent conditions with appropriate decay correction applied using the physical …

Plumbed 3-Manifolds And Neumann Moves, Noah J. Pope

Theses and Dissertations

We give a constructive proof that every weakly negative definite plumbing tree can be transformed into a negative definite one by a finite sequence of Neumann moves. The argument combines Neumann’s plumbing calculus with the diagonalization algorithm of Duchon, Eisenbud, and Neumann, which extracts the eigenvalues of the framing matrix directly from the combinatorics of the tree. We show that any positive eigenvalues are supported on linear branches and can be eliminated systematically via controlled applications of Neumann moves. This provides an explicit algorithm reducing weakly negative definite plumbing trees to negative definite ones.

The Transition From School To Work For Students With Emotional And Behavioral Disorders: Examining The Lived Experiences Of Students In Private Day Schools, Gabrielle S. Pickover

Theses and Dissertations

This qualitative phenomenological study examined the lived experiences of young adults with Emotional and Behavioral Disorders (EBD) as they transitioned from private day school settings into sustained employment. Guided by Schlossberg’s Transition Theory, the study explored participants’ perceptions of the barriers, supports, and strategies that shaped their transition experiences. Data were collected through twelve semi-structured interviews with six participants who maintained at least one year of continuous employment following high school. Analysis revealed four primary themes: structure as a stabilizing force, resilience developed through adversity, experiential learning as a pathway to employment, and employment as identity and independence. Findings suggest …

Waxing And Waning: Hidden Interiors Of Grassroots Expression, Asmita Baskar

Theses and Dissertations

Concealed interiors historically emerged from necessity in response to dominant systems around surveillance, control, and visibility. These hidden spaces carefully regulated access, cultivated intimacy, and enabled self-expression within grassroots groups and marginalized communities. Operating free from surveillance and in contrast to surrounding architectural and urban systems, these concealed spaces were not formally “interior designed”, yet they reveal how communities activate the interiors they encounter to retain agency.

Scholarship on grassroots resistance is largely examined through sociology, anthropology, psychology, or political science, with limited literature directly linking interiority, interior design, and resistance within covert spaces. This thesis addresses the gap in …

Musings Of A Dyke: Reimagining A Lesbian Past To Support A Lesbian Future, Tori Mitchell

Theses and Dissertations

This thesis interrogates the heterosexist bias inherent in historical narratives by recontextualizing myth, biblical accounts, folklore, and art history through a dedicated lesbian lens. Utilizing oil painting as my primary medium,  I construct a metafictional world–a pseudo-historical space where the foundational assumption is that every figure is a lesbian until proven otherwise. This inversion serves as a direct counter-narrative to the default lens of cis heteronormativity typically applied to the past. Within this world, I “lesbianize” the traditional icons of Western culture: the heroes, the symbols, and the deities.

My practice navigates the tension between reinvention and extinction, viewing both …

"It's The People, Not The Place:" Queering Shared Space In Richmond, Virginia, Kathleen Brown

Theses and Dissertations

The intersection of queerness and planning is an understudied subject area that has implications for equity and access. Queer communities face real barriers to equitable access of resources that stem from a long history of legal, cultural, and economic marginalization. Experiences of shared spaces for queer groups and organizations is important to understand, as outward expressions of queerness are not always welcome in shared spaces, depending on sociopolitical context. Richmond, Virginia has a rich queer history both filled with challenges as well as examples of queer success and joy that makes it a prime case study selection.

This thesis utilizes …

Exploring, Understanding, And Supporting Academic Help-Seeking In Context, Molly L. Taylor

Theses and Dissertations

Conceptualized as a self-regulated learning (SRL) strategy, academic help-seeking is a fascinating behavior because it is self-directed while also reliant on social interactions with help-givers (Karabenick, 2004). What is known about help-seeking in academic settings largely revolves around individual traits, strategies, motivations, beliefs, and identities, and how each of these constructs influence help-seeking outcomes (Bornschlegl et al., 2020; Fong et al., 2023; Karabenick & Gonida, 2018). What is underexplored in these areas, however, is how features of the learning context interact with student-level factors to shape academic help-seeking behaviors and beliefs. This dissertation attempts to address some of these gaps …

Tuberculosis In Jim Crow Virginia, 1900-1972, Elizabeth Dooley

Theses and Dissertations

Tuberculosis (TB) was a major public health concern in the United States, especially in the first half of the twentieth century. Transmission and treatment of the disease, which is spread between humans through close contact, was complicated by racial segregation laws in the South known as Jim Crow laws. Virginia subscribed to these laws, which played a role in how and where Black Virginians with TB could be treated. Segregated treatment facilities with an inadequate number of beds for the number of infected people and deaths in the state added to these complications of disease control and plan for eradication. …

Early Math Readiness And Later Achievement: A Longitudinal Study, Bailey Bontrager

Theses and Dissertations

The current body of literature provides much evidence that mathematics skills at the start of kindergarten are predictive of later mathematics achievement, and that students enrolled in early childhood education (ECE) programs are better prepared for mathematics at the start of kindergarten. However, the potential for children to develop mathematical skills prior to entering kindergarten relies on access to ECE programs and resources in families’ surrounding communities. Recent use of geospatial data collection techniques and measures of community resource availability have enabled researchers to examine specific localities for the ways in which community organizations and institutions support residents in particular …

Endodontic Access Through Zirconia Crowns: A Comparative Evaluation Of 3d Guided Versus Free-Handed Techniques, Maryam Alrughaib

Theses and Dissertations

Objective:

Accessing canals through full-coverage zirconia crowns is challenging and may increase the risk of misdirection, excessive dentin removal, and prolonged chair time. Guided endodontic access has been proposed to improve efficiency and precision. This study compared the accuracy and time efficiency of guided versus free-hand endodontic access through zirconia restorations. The hypothesis was that guided access would enhance canal localization precision and significantly reduce access time.

Methods:

Thirty-two extracted maxillary premolars were restored with 1-mm–reduced monolithic zirconia crowns (3Y-TZP, Katana HTML, Kuraray, Japan) and mounted in Modupro models. Teeth were assigned to two groups (n = 16 each): guided …

Climate, Biogeography, And Dispersal: A Unifying Framework For Ameri-Caribbean Dry Forests, Pablo Lopez Bustamante

Theses and Dissertations

Seed dispersal is a crucial ecological function that enables plants to alter their distributional range, avoid intense competition and natural enemies near the parent plant, and recover from disturbances. These processes shape species and functional composition of forests. Wind has traditionally been considered the dominant dispersal mechanism in Ameri-Caribbean dry forests, yet growing evidence suggests that other dispersal mechanisms also play significant roles in this ecosystem, responding differently to biotic and abiotic conditions. Still, how dispersal syndrome composition influences plant communities, the ecological drivers underlying these patterns, and the effects of climate change on dispersal syndrome dominance remain poorly understood. …

Positive Body Image In Postpartum Women: A Psychometric Evaluation Of The Body Appreciation Scale-2 And A Phenomenological Exploration, Taylor Vashro

Theses and Dissertations

Postpartum women appear particularly vulnerable to body dissatisfaction due to the rapid physiological, emotional, and environmental changes that occur across the perinatal experience (Baskin et al., 2021; Nippert et al., 2021). Recent studies have demonstrated the experience of both negative and positive body image during postpartum (Rodgers et al., 2024; Watson et al., 2016). However, there is limited research regarding the measurement and exploration of positive body image in postpartum women. The current study aimed to: 1) evaluate the factor structure and psychometric properties of the Body Appreciation Scale-2 (BAS-2), a widely used measure of positive body image in postpartum …

The Long Shadow Of The Boys In Blue: Civil War Memory & The Evolution Of Veteran Identity In Twentieth Century Pennsylvania, Alexander L. Barbolish

Theses and Dissertations

This thesis presents a case study of the transformation of veteran identity and civic culture in Northeastern Pennsylvania, tracing the profound shifts in the way Americans remembered war, commemorated sacrifice, and defined what it meant to be a veteran, from the turn of the twentieth century to the dawn of World War II. By examining the complex interactions and relationships between three distinct and overlapping generations of veterans—those of the Civil War, the Spanish-American War, and World War I—this study argues that veteran identity was neither static nor monolithic, but was continually renegotiated through commemorative practice, organizational culture, and public …

Film for Jeanette is an experimental documentary concerning grief, memory, and what remains of those who have left this physical plane. The film paints the portrait of my late sister, Jeanette Lee Goldberg, who died in a car accident when she was 19. What begins as a memorial becomes a celebration of her life and an exploration into the complexities of her character that led to her death. Jeanette’s story is told through interviews with family members, while the visuals, created with various alternative 16mm film techniques, depict my own journey through the filmmaking process. I was only 3 when …

Examining Mental Healthcare Underutilization Among Latino Immigrants: Healthcare Providers’ And Community Health Workers' Perspectives, Geovani Muñoz

Theses and Dissertations

Latinos continue to experience many logistical and systemic barriers to professional mental health services (Derr, 2016) despite being the second-largest racial-ethnic group in the United States (U.S.). With a community of 65 million people (U.S. Census Bureau, 2024), Latinos experience mental healthcare inequalities (Cook et al., 2019) due to structural, cultural, and systemic barriers. Although prior research has emphasized culturally responsive care as a pathway to reducing disparities (Nagy et al., 2025), much of the literature has focused on Western medical models, with limited attention to community-based perspective. Guided by the Knowledge, Attitude, and Practices (KAP) framework, the present study …

Mathematical Models With Clinical Applications For Improving Health Outcomes, Helen Harris

Theses and Dissertations

In clinical settings, patients are exposed to many risks and stressors that could result in adverse health outcomes. Here we present mathematical models that seek to address these risks. First, we present a Markov Chain model to investigate the effect of medication reconciliation (MR) completion on patient health outcomes in the intensive care unit. Using this model, we simulate the annual incidence of adverse drug events (ADEs) for three different ADE rates. Based on the simulated results, we conduct a cost-benefit analysis for various levels of compliance to determine the financial implications of increasing MR completion depending on the baseline …

Re-Sense, Nneoma Njoku

Theses and Dissertations

Re-Sense examines artist’s books as perceptual tools capable of reshaping how readers encounter history, memory, and archival absence. Beginning with the idea that books teach us how to know and how to see, the text argues that conventional book structures often reinforce Western knowledge systems through overemphasis of linearity, coherence, and containment. In contrast, artist’s books' experimental structures support novel modes of knowing and relation to ourselves and the world of humans and non-humans. The author describes this process of exhuming perception from Western constraints as re-sensing.

Through re-sensing, the historical past becomes less like a fixed record and more …

Nanomagnet Based Reservoir Computing And Quantum Control, Fahim F. Chowdhury

Theses and Dissertations

Conventional CMOS scaling has driven remarkable advances in computing but faces increasing physical and energy constraints, motivating alternative computing paradigms that integrate memory and computation while improving energy efficiency. Nanoscale magnetic systems offer a promising platform for such approaches because their intrinsic nonlinear dynamics and localized magnetic fields can support both classical and quantum information processing. This thesis investigates nanomagnetic systems for physical reservoir computing and, with primary emphasis, for localized quantum control of spin qubits.

The first part explores dipole-coupled nanomagnet arrays as physical reservoirs. Micromagnetic simulations demonstrate nonlinear dynamical behavior with high short-term memory and parity-check capacity, enabling …

Managing Identity, Claiming Expertise, And Emotional Labor: A Constructivist Grounded Theory Of The Experience Of People With Serious Mental Illnesses In Primary Care, Jeffrey Ciak

Theses and Dissertations

People with serious mental illnesses (SMI) die 15 to 20 years before their peers without mental illness primarily due to chronic physical health conditions. Preventative care and treatment for chronic physical health conditions primarily occurs through primary care, but the experience of people with SMI in primary care is understudied. This constructivist grounded theory dissertation explored the experiences of people with SMI in primary care. Theoretical sampling resulted in 19 participants who were adults with SMI and long-term anti-psychotic use. Data was collected through one-to-two-hour long intensive interviews. The analytical process occurred concurrently with data collection. The abductive analytical process …

Modeling Of Laser-Produced Plasma Plumes: Expansion, Chemistry, And Thin-Film Deposition, Edmund Tsiri Semaha, Edmund Tsiri Semaha

Theses and Dissertations

Abstract

Laser-assisted material processing involves coupled plasma expansion, chemical reactions, and particle transport that govern the quality of thin-film deposition. This dissertation presents a comprehensive computational investigation of these processes using the OpenFOAM framework. First, the performance of the twoPhaseEulerFoam (tPEF), rhoCentralFoam (rCF), and sonicFoam (sF) solvers is evaluated for modeling laser-produced plasma plume expansion under atmospheric conditions, demonstrating that tPEF accurately captures shock-wave propagation, hydrodynamic behavior, and multispecies interactions. Building on this validation, the reactingFoam (rF) solver is employed to investigate the chemistry of aluminum plasma expanding into an air environment (Al–N₂–O₂). The model incorporates appropriate thermodynamic, transport, and …

The Influence Of Metacognition On College Readiness And Persistence, Michael L. Fitzgerald

Theses and Dissertations

This applied dissertation examined the influence that metacognition has on college readiness and its most traditionally used metrics: performance-based outcomes and persistence. Specifically, this study addressed to what degree underlying metacognitive structures differ between college students’ successful metrics of performance and persistence compared to a more general sample of college students.

The research characterized metacognition along three domains of analysis: (a) selfefficacy/ motivation, (b) soft skills/psychological capital (Psycap), and (c) expected value of control (EVC). The quantitative study included 54 college students and a crosssectional design. Participants completed a four-part Likert-style survey, where their responses were measured along the three …

The study examined how organized small-group direct instruction can elevate students’ reading achievement in phonics, vocabulary, and reading comprehension. Over a six week instructional period, a mixed-methods research design was used to collect quantitative and qualitative data.

Pretest and posttest students’ reading assessments were collected using quantitative data, while teachers' weekly reflections and surveys were collected using qualitative data. A total of 30 students identified as struggling readers, and three second-grade teachers who implemented small-group direct instruction participated in …

Student Centered Approaches To Analyzing Engagement And Discourse, Kamil Hankour

Theses and Dissertations

Student engagement and participation in classroom discourse are widely recognized as powerful predictors of meaningful science learning, yet students’ own perspectives on the factors that shape their engagement and participation are currently underexamined. Prior research has established strong links between engagement, discourse and outcomes such as academic achievement (Bae & DeBusk-Lane, 2019; Fredricks et al., 2004; Sedova et al., 2019), but less is known about how students understand and interpret their experiences across individual, group-level and classroom contexts, particularly within historically marginalized populations (Cook-Sather, 2013; Schaefer et al., 2024). This three paper dissertation advances a line of inquiry integrating a …

Tangled Up In Blues, Clara B. Deweese

Theses and Dissertations

Martin Buber’s philosophy teaches us that when our masks fall and our armor’s unveiled, we discover humanity shared. Tangled Up in Blues unpacks the snapshot photographic practice I’ve had for years, which documents my mutually uplifting relationships, and is presented for my thesis exhibit through a painterly technique that deconstructs and reconstructs  the images onto wood panels using laser transfer. As we navigate a distracted and fragmented society made of greed and bigotry, cherishing the deep connections and shared memories brings us optimism.
