I Will Defend My Self, Emily Ward Hawkins

Theses and Dissertations

This thesis examines caregiving and motherhood as forms of load-bearing infrastructure. Cultural narratives often portray motherhood through sentimental images of joy, tenderness, and devotion, obscuring the structural labor that sustains family life. This project examines maternal labor as a largely unseen system of support that organizes family life while often remaining backgrounded. Caregiving reorganizes time, space, ambition, embodiment, and future orientation within maternal life. Through sculptural works using architectural materials and construction systems, such as oriented strand board, blueprint racks, metal armatures, and graph paper, the project visualizes caregiving as a structural condition. These materials reference the language of architecture …

Theses and Dissertations

This study examined the effects of Timed Repeated Reading (TRR) on reading fluency, comprehension, and reading attitudes among second grade students in a French Dual Language Immersion (DLI) program in Utah. Forty-one students from two pre-existing classroom groups participated over 11 weeks, with one class receiving TRR and the other serving as a control. Fluency was measured in correct words per minute (CWPM), comprehension through cloze tests, and attitudes using a seven-item affective survey with a four-point visual scale. A mixed between-within subjects ANOVA analysed pre- and post-test data across four intervals. Results showed significant fluency gains over time for …

Beyond The Bell Curve: Understanding Native American Academic Placements, Sarah-Margaret Clark

Theses and Dissertations

This study examined biases regarding the referrals that teachers make regarding student placement recommendations for Native American students. Special education teachers (n = 97) from around the United States completed a digital card sort task involving 24 fictitious student record cards. The student record cards contained subtle information about the ethnicity of the student, as indicated through the use of racial identification (Native American, Asian, or White) on the student records and the use of student names that may be associated with these three categories. Academic information was equal among each of these three groups. Each group contained identical male …

Calibration And Validation Of An Ogden Material Model For Thermoplastic Polyurethane In 3d-Printed Tensegrity Structures, Caleb C. Swain

Theses and Dissertations

This work is motivated by ongoing efforts within the Smart Materials, Adaptronics, and Shock Laboratory (SMASH Lab) at Brigham Young University (BYU) to develop variable-stiffness, external fixators using 3D-printed tensegrity structures. In the process of designing and evaluating these systems, the need arose to accurately model the nonlinear mechanical behavior of thermoplastic polyurethane (TPU), the primary material used in prototype fabrication. This thesis investigates how accurately a calibrated Ogden material model can predict the nonlinear mechanical response of TPU in 3D-printed tensegrity structures. Experimental data were used to calibrate the parameters of the hyperelastic constitutive model through nonlinear optimization. An …

Exploring Generative Artificial Intelligence Perceptions And Information Retrieval Behaviors Among Students: An Investigation Of Google Search And Chatgpt Queries, Annie Kiele Brown

Theses and Dissertations

Generative AI tools are rapidly reshaping how undergraduate students seek and engage with academic information, yet empirical understanding of what drives adoption and how students behave when using these tools relative to traditional search engines remains limited. This study examined undergraduate students’ information-retrieval behaviors and perceptions when using ChatGPT compared to Google Search, using the technology acceptance model (TAM; Davis, 1989) extended to include trust (Gefen et al., 2003) as the guiding framework. An embedded mixed-methods design was employed, in which Likert-scale perception ratings provided a structured quantitative signal and thematic analysis of semi-structured interviews, structured information-retrieval tasks, and concurrent …

Unlocking Potential: Teachers' Perspectives On 504 Accommodations For Students With Adhd, Haley Stubbs

Theses and Dissertations

This study examined high school teachers' perspectives on the development, implementation, and effectiveness of Section 504 accommodations for students with ADHD. Five secondary teachers from a public high school participated in a focus group, and data were analyzed using inductive thematic analysis. Findings indicate that teachers report limited understanding of the 504 process, minimal involvement in eligibility decisions, and little training on how to implement accommodations. Teachers describe accommodations as vague and difficult to apply consistently within the constraints of secondary classrooms, often relying on universal classroom practices and student self-advocacy to meet student needs. Teachers also question whether accommodations …

Engineering 3d Optical Interconnects And Low-Power Radio Frequency Gaze Tracking, Blake P. Crosby

Theses and Dissertations

This thesis presents two independent research works in optical in- terconnects and radio-frequency (RF)-based gaze tracking. The first work demonstrates a silicon optical waveguide fabricated from four through-silicon vias (TSVs) produced using two-photon-absorption- assisted photo-electrochemical etching. Unlike conventional TSV fabrica- tion methods, this approach enables highly localized, non-line-of-sight etching in silicon using a focused femtosecond laser. Four approximately 5 μm diameter TSVs were etched through a 200 μm silicon wafer in a 7 μm by 7 μm pattern, leaving a central silicon region that functions as a waveguide. The fabricated structure achieved an aspect ratio of approxi- mately 40:1 with …

Effects Of A Peer Mentoring Program For Adolescent Newcomers On Feelings Of Peer Connectedness And School Belonging, Eden Elizabeth Moon Barnhill

Theses and Dissertations

There is a significant lack of empirical evidence regarding the effectiveness of peer mentoring to support newcomer students, particularly for refugee populations. This study evaluated the effects of a peer mentor program for newcomer students on their feelings of peer connectedness and school belonging in a high school setting. Participants were made up of 15 newcomer student mentees across three high schools. Measures were administered pre- and post-intervention, and participants were also interviewed about their experience. Results indicated no quantitative findings of significance but did yield a small positive effect size for peer connectedness. According to qualitative data, many participants …

Hierarchical Parcel Swapping: A Novel Model In Turbulence, Masoomeh Behrang

Theses and Dissertations

Turbulent mixing plays a central role in a wide range of engineering and natural systems, particularly in reactive flows where turbulence--chemistry interactions strongly influence reaction rates, flame structure, and emissions. Accurately modeling these interactions remains a major challenge due to the multiscale and stochastic nature of turbulence, as well as the nonlinear coupling between transport and chemical kinetics. This dissertation develops and evaluates the Hierarchical Parcel Swapping (HiPS) model, a fully stochastic framework designed to represent turbulence-driven transport and scalar mixing without relying on traditional gradient-based closures. HiPS is investigated both as a standalone turbulence model and as a subgrid …

Service Providers' Descriptions Of Survivors' Experiences With Mental Health Treatment, Melanie Gonzales Puente

Theses and Dissertations

Human trafficking survivors experience significant mental health challenges and barriers that limit their engagement towards treatment. A qualitative study was conducted that included semi-structured interviews of 33 professionals working with survivors of human trafficking in the United States. Findings indicate that survivors' engagement in treatment is limited by mistrust of providers, stigma, and a lack of access to services. Providers emphasize that addressing basic needs (e.g., safety and housing) must occur before engaging in trauma-focused therapy. Positive outcomes are associated with strong therapeutic relationships, autonomy, trauma-informed, individualized care, and offering comprehensive services. Furthermore, mental health providers should have certain abilities …

Empirical Analysis On Multi-Agent Reinforcement Learning Frameworks, Jordan Jiosi

Theses and Dissertations

Increasingly, automated agents operating in the physical world are expected to perform previously unseen tasks at levels comparable to human experts. Solutions to these challenges typically fall along a spectrum between model-based and model-free reinforcement learning (RL) approaches. Encouraging expert-like behavior in reinforcement learning is often difficult because reward functions can be challenging to specify accurately. Inverse reinforcement learning addresses this problem by inferring reward functions directly from expert demonstrations rather than relying on manually engineered objectives. This thesis examines the performance of both on-policy and off-policy model-free reinforcement learning algorithms, including Proximal Policy Optimization (PPO) and Deep Deterministic Policy …

A Rho5-Cnc1-Dnm1 Signalling Module Coordinates Multi-Organelle Execution Of Regulated Cell Death In Yeast, Justin Bauer

Theses and Dissertations

Regulated cell death is a conserved process with major implications for health and disease, yet how yeast cells integrate stress signals to determine survival versus death remains unclear. This thesis investigates Cyclin C (Cnc1), a conserved Mediator kinase module component with both transcriptional and mitochondrial roles. Together with Cdk8 Cnc1 primarily represses stress response genes, while upon stress it translocates to the mitochondria to induce mitochondrial fragmentation with the dynamin-related GTPase Dnm1. Using structure-guided separation-of-function mutants, I demonstrate that Cnc1-dependent death requires its mitochondrial function rather than its transcriptional role, and that its effector Dnm1 acts as a signaling node …

Anatomy And Function Of Vasopressin Receptor 1a-Expressing Neurons In The Limbic Thalamus, David Joseph Kahn

Theses and Dissertations

The vasopressin (Avp) system modulates social behavior through region-specific and sex-dependent mechanisms, yet the role of Avp receptor 1a (Avpr1a) signaling in the thalamus has remained largely unexplored. This dissertation examined the distribution and functional contributions of Avpr1a-expressing neurons across the mouse thalamus using a combination of genetic labeling, anatomical quantification, and chemogenetic manipulation. Mapping of Avpr1a-expressing neurons revealed a presence in most thalamic nuclei, with highest densities in the anterior thalamic nuclei and midline nuclei. Notably, Avpr1a-expressing neuron densities did not mirror previously described patterns of Avp innervation, and no sex differences in Avpr1a-expressing neuron density were observed. Chemogenetic …

Development And Standardization Of Teds Actuator Templates Under Ieee 1451 Framework, Jim Kang

Theses and Dissertations

The IEEE 1451 standard is a family of standards that defines a framework for smart transducers, including both sensors and actuators, to support consistent, interoperable, and cost-effective integration across diverse applications. However, the current IEEE 1451.4 standard templates only define the method for encoding Transducer Electronic Data Sheet (TEDS) information for a broad range of sensor types and applications; they do not address actuator TEDS. Specific types of sensors and actuators are being developed to assess underground environmental conditions in cold regions with widespread permafrost. Evaluating subsurface conditions before construction can help prevent high construction expenses for structures built on …

Engagement With Tailored Physical Activity Interventions Among Women In Midlife With Elevated Risk For Cardiovascular Disease, Kiri Baga

Theses and Dissertations

Women in midlife (ages 40-65) with risk factors for cardiovascular disease (CVD) need physical activity (PA) interventions that are informed by and address their daily challenges and life circumstances, to reduce their chances of premature mortality from CVD. Sustaining engagement with PA interventions remains a substantial challenge for women in midlife. The aims of the proposed study were to describe participants’ PA-relevant characteristics and intervention preferences and to identify their patterns of engagement with different PA support tools (tailored PA website, intervention involving pairing women as PA partners). With respect to engagement, there was limited between-person stability in engagement outcomes …

This historical study investigated the role and experiences of the ten women in the Camden 28, which was a group of Catholic Leftists who raided the draft board in Camden, NJ in 1971 to protest the Vietnam War. In utilizing a myriad of sources from archival collections through scarcely seen personal ephemera to correspondence with individuals connected to this case, this thesis demonstrated the importance of these women to the planning and execution of the raid as well as their significance to the outcome of the trial in 1973. It also showed the need for targeted scholarship on them. Furthermore, …

The Human Side Of Humanitarian Work: Well-Being And Performance Among Aid Workers In Egypt, Mai Osama Kenawy

Theses and Dissertations

Well-being and productivity are widely recognized as central to the work performance of humanitarian aid workers. Despite increasing attention to staff well-being, performance within the humanitarian sector in Egypt remains stagnant or, in some cases, declining. This study examines why expanded well-being initiatives have not yielded sustained performance improvements by examining how actors' external roles, organizational factors, and individual factors affect humanitarian workers’ well-being and work performance. A mixed-methods approach was adopted, combining ten in-depth interviews with humanitarian workers from international organizations, INGOs, and local NGOs, as well as a survey of eighty workers operating in the same context. The …

“Between Cultural Norms And Economic Survival: Navigating Egyptian Lower And Middle Income Women’S Challenges In The Informal Versus The Formal Work: “A Case Study From Cairo”, Rowan Mahmoud Abdelnazer

Theses and Dissertations

This study investigates the ongoing gender inequities experienced by low and middle-income women in Egypt’s formal and informal labor economy, specifically it is based in Cairo. Although there are many advances made globally on women's rights, yet women still face great challenges such as discrepancies in salary, fewer leadership roles and cultural expectations which put child-bearing duties before professional growth. On the one hand, flexible work for women in developing countries is through informal sector, which makes them vulnerable and serves as a source of their exploitation and insecurity (e.g., lack of social security; workplace hazards), on the other hand, …

Work Precarity, Mental Health, And Performance Among Humanitarian Aid Workers In Egypt Post-2025 U.S. Funding Reduction, Mariam Allam

Theses and Dissertations

The humanitarian sector is increasingly characterized by precarious employment conditions and work precarity, including short-term contracts, unclear renewal terms, inadequate compensation, heavy workloads, and job insecurity, exacerbated by volatile donor funding. The 2025 U.S. funding cuts have intensified these vulnerabilities, particularly in countries like Egypt, with massive humanitarian operations because of being a significant destination for asylum applications and one of the largest refugee host countries. Despite the prevalence of precarious work in the humanitarian sector, limited research examines its effects on workers' mental health and work performance, especially during funding crises. This qualitative study explores the perceived effect of …

Integrative Assessment Of Body Composition And Micronutrient Status In An Adult Egyptian Population, Roua Aref Nouh

Theses and Dissertations

Integrative Assessment of Body Composition and Micronutrient Status in an Adult Egyptian Population: A Functional and Biochemical Approach

Obesity and metabolic dysfunction are increasingly recognized as heterogeneous conditions that cannot be sufficiently characterized by body mass index (BMI) alone. Alterations in body composition, particularly central adiposity and skeletal muscle mass, may coexist with micronutrient imbalances even among individuals who fall outside conventional BMI-based obesity classifications. In clinical settings, such metabolic vulnerability is frequently accompanied by non-specific functional symptoms, highlighting the need for integrative assessment approaches that extend beyond weight-centered metrics. This cross-sectional study aimed to investigate the associations between micronutrient …

Philosophia From Dialectic To Dying Before Death: Traces Of Plato’S Spirit In The Encounters Between The Falāsifa, Mutakallimūn, And Sūfiyya, Fadhil Yunus Alsagoff

Theses and Dissertations

This thesis offers a fresh approach to the question “What is philosophy?” by reconsidering Plato’s vision of philosophiaand seeking its traces in the encounters between the Falāsifa, the Mutakallimūn, and the Sūfiyya of the classical Muslim world. I argue that Plato’s true legacy lies in a vision of philosophia as dialectical inquiry that ultimately leads – due to the inextricable limitations of propositional language – to aporia and what he called “practicing for dying and death.” I then argue that this vision of philosophia finds resonance in the classical Muslim world in the embodied encounters between …

The Experience Of Newly Formed Syrian Female-Headed Households Refugees In Egypt: Challenges And Opportunities, Wasim Dia

Theses and Dissertations

This thesis examines the lived experience of Newly Formed Syrian Female-Headed Households in Egypt. It focuses on how the extended displacement reshapes gender roles, decision-making, and survival strategies. Since the beginning of the Syrian conflict in 2011, extensive family separation, death, disappearance, and male migration have occurred, leading to a significant rise in female-headed Syrian refugee households. As a result, displacement has intensified women’s vulnerability, generating new responsibilities and limited spaces for agency, especially within restrictive legal and socio-economic environments.

Based on in-depth qualitative interviews conducted in 2023, this research explores how Syrian refugee women navigate everyday life in Egypt …

Sense Of Belonging Among Undergraduate Students At The American University In Cairo: Demographic Trends, Barriers And Facilitators, Lamiaa M. Mohamed

Theses and Dissertations

A sense of belonging is widely recognized as a key determinant of undergraduate students’ academic success, well-being, and persistence in higher education. However, existing research is largely grounded in Western contexts and often emphasizes institution-level measures, with limited attention to how belonging is experienced and constructed by students in non-Western settings. This study examines undergraduate students’ sense of belonging at the American University in Cairo, focusing on factors that shape belonging and institutional practices that may strengthen it. Using a sequential mixed-methods design, the study examined 87 responses from a quantitative survey adapted from the University Belonging Questionnaire, followed by …

Scruples Before Religion: Muslim Waraʿ Of The Formative Period, Omar Laaroussi

Theses and Dissertations

This thesis studies the conceptual history of waraʿ and its role as a normative paradigm existing in the formative centuries of the Islamic world. To do so, I consider the Hellenic concepts that ground Near Eastern understandings of virtue and piety before the rise of Islam. This, I then use to contextualise a focused discussion on the textual history of waraʿ before moving on to discuss its properties in a ascetic social-world through the analysis of those very texts. I attempt to place those properties in conversation with modern philosophers’ work on disciplinary regimes and their impacts upon the self. …

Parental Gender Bias In Youth Employment Standards: Evidence From Upper Egypt, Mahmoud Saeed

Theses and Dissertations

Youth unemployment remains a critical challenge in Egypt, with female labor force participation among the lowest globally. While structural factors such as limited job creation and public sector contraction are well-documented, the role of family-level decision-making in constraining women's labor market entry has received limited quantitative attention. This thesis examines parental gender bias in employment standards in Upper Egypt, investigating whether and how parents impose systematically different job requirements for daughters compared to sons. Using primary survey data from 17,284 unemployed youth aged 18-35 across six governorates, paired with responses from their parents, this study analyzes parental preferences across six …

Tuning Ion Mobility And Molecular Confinement In High-Performance Polymer Electrolytes For Energy Storage, Ezzeldien Yousef Muhammed Yousef

Theses and Dissertations

This research addresses the critical energy density limitations of aqueous supercapacitors, which are traditionally constrained by the narrow electrochemical stability window (ESW) of water 1.23 V. By employing two distinct molecular engineering strategies, this study developed high-performance electrolyte systems that significantly extend voltage stability and thermal resilience.

The first system, CsBr@PAM/HA, utilizes a polyacrylamide and hyaluronic acid hydrogel matrix. This system exploits the chaotropic nature of Cs⁺ ions to disrupt the aqueous hydrogen-bonding network, enhancing ionic conductivity to 104 mS cm^-1. Through systematic salt screening, CsBr was identified as the optimal electrolyte, enabling a stable 2.0 V …

Social Identity And Language Learning/Teaching Trajectories: Egyptian English Teachers’ Reflections On Being Taught By Native English- Speaking Instructors, Asmaa Mohamed Badawy

Theses and Dissertations

This study explores how teacher social identity is shaped by Egyptian English teachers’ past learning experiences, particularly in relation to native and non-native English-speaking teachers. It seeks to understand how these experiences influence teachers’ perceptions of themselves within English-speaking contexts and how they make sense of dominant language ideologies surrounding nativeness. The study is guided by the following research questions: how participants perceive their sense of social belonging within English-speaking contexts; how ‘native’ and ‘non-native’ English teachers understand and interpret nativeness; and how past educational and social experiences shape teachers’ sense of ownership and legitimacy. Situated within the framework of …

How Disability Inclusion Shapes Student Experiences In Egyptian Public Universities, Ramez Maher

Theses and Dissertations

The inclusion of students with disabilities in higher education is a critical aspect of equity, social justice, and human rights, particularly in Egypt, where systemic barriers continue to hinder access to education for this demographic. Despite the enrollment of approximately 19.4 million students in 2018, only 38,135 students with disabilities were admitted, highlighting the significant challenges they face in accessing higher education.   Through a qualitative approach employing reflexive thematic analysis, this study explores the interplay of institutional policies, cultural attitudes, and accessibility challenges that affect the educational experiences of students with disabilities in Egyptian public universities.
