Building A Cell Specific System For In Vivo Rna Imaging Of The Endogenous Actin Gene In C. Elegans, Jasmine A. Huerta Canete

Theses and Dissertations

Messenger RNA (mRNA) plays a crucial role in protein synthesis and cellular processes, important for the development of cells such as neurons. When dysregulation occurs, it can lead to outcomes such as aberrant translation, causing neurodegenerative conditions to arise. Unfortunately, the localization of mRNA in an in vivo cell specific manner is still not understood. To address this, we decided to develop a cell-specific system to image RNA in vivo, within the organism known as C. elegans with a focus on the actin gene. The Actin gene encodes for an important cytoskeleton protein expressed ubiquitously, vital for the cell …

Graduate Student Retention: Examining Why Master’S Students Leave And What Motivates Their Return In A Large Public University System, Sonja Prophete

Theses and Dissertations

Graduate student persistence is a relatively unexplored area in the literature of higher education studies; specifically, at a multi-institutional scale at the master's level. This research study examines the factors which cause students to discontinue their master's degrees, and what conditions could possibly support them returning to their program at a large urban public university system. The current study was guided by Hoyt and Winn's (2004) distinction between non-returning students, and Bean & Metzner's (1985) theoretical model of student attrition. A sequential mixed-methods study was conducted to examine the institutional and environmental influences on students' decision-making processes.

The quantitative data …

Generating Synthetic Ct From Mri Data, Foysal Ahmed

Theses and Dissertations

Magnetic resonance imaging (MRI) provides excellent soft tissue contrast without ionizing radiation, making it a strong alternative to computed tomography (CT) in medical imaging workflows. However, CT remains essential for applications requiring electron density information, such as radiation therapy treatment planning.

A two-dimensional U-Net was trained on paired MRI-CT data from the SynthRAD 2025 dataset, consisting of 120 T1-weighted (T1W) and 60 T2-weighted (T2W) axial cases, including deformed CT (dCT) aligned to MRI. Model testing used an independent dataset of 30 …

Use Of Transcranial Magnetic Stimulation As An Assessment Of Corticospinal Excitability In Individuals With Persistent Postural Perceptual Dizziness, Elizabeth Cornforth

Theses and Dissertations

Persistent postural-perceptual dizziness (PPPD) is a common, disabling, chronic vestibular disorder whereby individuals experience symptoms of non-vertiginous dizziness, unsteadiness, and sway or rocking that are present most hours of the day, most days of the week. Individuals with PPPD have been noted to have an increased burden of dizziness and reduced quality of life compared to other dizziness diagnoses. The cause of PPPD is not well understood which can lead to years of diagnostic testing, failed therapies, and poor symptom management. It is important to understand PPPD pathophysiology so that optimal treatment interventions can be developed for this disorder to …

Walking And Wondering, Helen T. Tran

Theses and Dissertations

My thesis approaches walking as a form of inquiry and the Flood Wall as a site open to reinterpretation. I believe that the way we walk changes the way we observe and experience the world around us. This contrast between purposeful and leisurely walking reveals how time and intention shape our awareness of space. When walking is no longer dictated by urgency, it invites observations and questions. Slowing our pace allows curiosity to emerge, which aligns with my design ethos of asking questions as a foundation for understanding and creating meaningful experiences.

The Flood Wall’s emphasis on uninterrupted movement prioritizes …

Both stationary (hovering) and trajectory-following experiments are conducted to evaluate system performance. Communication delays in …

In Search Of The Soul Of Creativity: Authorship, Agency, And Meaning In Refractive Collaboration With Generative Ai, Fatima Nazir

Theses and Dissertations

When images can be generated in seconds, what remains uniquely human in the act of creation? In Search of the Soul of Creativity: Authorship, Agency, and Meaning in Refractive Collaboration with Generative AI investigates where authorship, agency, and meaning reside within design practices mediated by generative AI. Rather than using AI to produce predictable results, this research deliberately relinquishes control to observe how generative systems interpret language through their own learned associations. Through a practice-led investigation across four generative models within the Higgsfield platform, user prompts were progressively shortened from full sentences to single words, revealing recurring patterns and cultural …

Thinking Machines: Cybernetics, Artificial Intelligence, And Technological Anxiety In The American Cold War, Erin Mae Wilcox

Theses and Dissertations

Following the Second World War, cybernetics emerged as a cross-disciplinary study in philosophy, neurophysiology, electrical engineering, and mathematics. Cyberneticists proposed the formal study of the man-machine analogy; that is, to equate biological structures to a complex mechanical system. Drawing from this analogy, cyberneticists used programmable digital computers to emulate the functions of the human brain. The study of artificial intelligence emerged within this cybernetic discourse in the early 1950s; yet, by the mid-1960s, the two disciplines suffered a methodological fracture. Drawing from a tradition generated by this fracture, historians have traditionally examined cybernetics and artificial intelligence in isolation from one …

Data Defines Success: Algorithm For Dataset Quality Assessment In Deep Learning For Malware Detection, Matei Ionescu

Theses and Dissertations

The field of artificial intelligence is based upon the premise of constructing architectures through which to propagate training data. However, the majority of existing research literature is focused on architecture. While necessary, the attention devoted to the architecture should not so precipitously exceed that of the data. It should be noted that this disparity is not without reasonable cause. Data quality is often exceedingly difficult to verify due to particularities of the field or subfield; LLM repositories of text are distinct from image recognition pictures of dog breeds which are distinct from EEG waveforms of human brains which are distinct …

From Deference To Dialogue: How International Gtas From High Power Distance Cultures Adapt To U.S. Classroom Dynamics, Deborah Akua Afi Appiah

Theses and Dissertations

International graduate teaching assistants (GTAs) from high power distance cultures play a significant role in undergraduate education at U.S. universities, yet they face challenges that go well beyond language proficiency. Coming from educational backgrounds where teacher authority is unquestioned and hierarchical, these GTAs must navigate American classrooms that operate on fundamentally different assumptions, where authority is earned rather than assumed, informality is the norm, and students expect to question, negotiate, and be personally known by their instructors. The present study examined how eighteen (18) international GTAs from seven (7) high power distance countries perceived and adapted to these differences while …

Data-Driven Partitioning In Distributed Optimization For Networked Systems, Prosper Azameti

Theses and Dissertations

The convergence behavior of distributed optimal power flow (OPF) depends strongly on how the power network is partitioned into regions. Classical graph-based methods such as METIS are widely used, but they rely mainly on static topological criteria and do not explicitly incorporate operating-point-dependent information that may affect distributed optimization performance. This thesis develops a data-driven partitioning framework for distributed OPF using graph neural networks (GNNs). Each OPF scenario is represented as a graph in which buses are nodes and transmission lines are edges. Node and edge features capture both structural and operational characteristics of the network. Partition prediction is formulated …

Enhancing Hospital Length Of Stay Using Ai Agent Modular Capabilities, Dami Fred

Theses and Dissertations

Hospital Length of Stay (LOS) analysis is essential for managing hospital efficiency and financial performance, yet the analytical depth required remains inaccessible to many organizations due to technical and resource constraints. This thesis introduces the AI Agent Modular Capabilities (AIAM) framework, which decomposes LOS analysis into discrete, codifiable capabilities integrated into a single skill activatable with one prompt. Seven AI Agent Modular Capabilities were developed using a Work Breakdown Structure and tested against a simulated hospital scenario across three successive skill versions. Results demonstrate that the packaged AIAM skill produces comprehensive, consistent, multi-section LOS analyses from a single interaction, outperforming …

Abject And Uncanny Manifestations Of Sexuality And Sexual Desire In Nineteenth-Century Gothic Literature, Varvara Kuznetsova

Theses and Dissertations

This thesis explores the ways in which psychoanalytic concepts of the abjection and the uncanny were used to depict monsters and monstrous bodies in nineteenth-century Gothic literature as a site of social, cultural, and sexual transgression. Through the intersections of queer theory, monster theory, and psychoanalytic theory, I examine and analyze depictions of women as monstrous figures in Samuel Taylor Coleridge’s Christabel (1816), Mary Shelley’s Frankenstein; or, The Modern Prometheus (1818), and Sheridan Joseph Le Fanu’s Carmilla (1872). In particular, I aim to detail how language and descriptions of women monsters become coded elements that reveal monstrosity and transgression.

Fostering A Growth Mindset In Mathematics: Faculty And Student Experiences, Yolanda G. Rush

Theses and Dissertations

According to the Center for Community College Student Engagement (2019), many students attending two-year institutions need productive persistence strategies, including the development of a growth mindset. Although some growth mindset interventions have been effective in improving academic achievement among students (Boaler, 2016; Canning et al., 2024) and persistence (Lewis, 2019) among students, especially those with developmental needs (Suh et al., 2019) and those in mathematics, little is known about the experiences of students and teachers (i.e., students’ perceptions of teachers’ intentions and implementation) as teachers work to foster a growth mindset culture (Murphy et al., 2021). In this dissertation, I …

The Role Of Non-Academic Staff In First-Year Retention At Regional, Comprehensive Universities, Marco A. Krcatovich Ii

Theses and Dissertations

Regional comprehensive universities (RCUs) serve a large share of U.S. undergraduates, yet the role of non‑academic staff in shaping first‑year retention remains understudied. This dissertation examines how staff diversity and staffing structures relate to student persistence using seven years of IPEDS panel data and Linear Mixed‑Effects Models. Analyses were conducted separately for residential and commuter RCUs to reflect their distinct engagement environments. Findings show that staff diversity is significantly associated with retention, though the direction and magnitude vary by campus type and staff role. Staffing structure also matters as higher proportions of full‑time staff are positively associated with retention at …

The findings indicate that staff had moderately negative attitudes toward AI while also expressing some concerns. The results suggest that more resources and support for AI are needed for staff to address concerns. It also suggests that construct-level analysis …

First- And Second-Generation Immigrant Emerging Adults’ Career Aspirations, Laura A. Botros

Theses and Dissertations

Despite first- and second-generation immigrants making up 19.6% of the U.S. workforce (U.S. Bureau of Labor Statistics, 2024), research exploring their career aspirations is scarce. Studies show that individuals’ cultural backgrounds significantly shape first- and second-generation immigrants' career aspirations, values, and professional goals (Kao, 2004; Polenova et al., 2017). The purpose of the study is to examine how first- and second-generation immigrant emerging adults' cultural backgrounds inform their career aspirations. I utilized a qualitative approach by asking participants about their cultural background, career aspirations, and what influenced their career aspirations. Interviews and a cognitive map activity were conducted to investigate …
