Bayesian Spatiotemporal Model For Counterfactual Estimation In Socioeconomic Studies, Duwani W. Gonzalez

Statistical Science Theses and Dissertations

Impact evaluations of regional development programs often require estimating counterfactual outcomes for a small number of treated regions using survey-based areal data. In practice, evaluators typically rely on two-group quasi-experimental methods such as propensity score matching (PSM) and Difference-in-Differences (DiD). These approaches perform poorly when only a few regions receive treatment, and when the set of observed covariates is limited or only partially relevant. Moreover, they typically do not explicitly exploit the spatial and temporal dependence present in survey-based areal data such as in ACS (American Community Survey). This dissertation develops a family of Bayesian spatial predictive models for directly …

Advanced Finite Element Modeling And Design Enhancement Of Slender Square Concrete-Filled Double-Skin Steel Tubular Columns, Mahmoud T. Nawar, Ayman El-Zohairy, Mohamed Emara, Raghda I. Halima

Faculty Publications

Limited research exists on the behavior of square CFDST slender columns, especially under the consideration of the relation global buckling and confinement effect. This study evaluates square concrete-filled double-skin steel tubular (CFDST) columns using nonlinear finite element analysis (FEA) to simulate structural behavior under axial and eccentric loads until failure. Parametric analyses of extensive specimens of square CFDST pinended columns evaluate various parameters, providing design insights for engineering applications. The study was conducted over a wide range of slenderness ratios. Four concrete varieties with compressive strengths were tested: normal concrete (NC), engineered cementitious composites (ECCs), high-strength concrete (HSC), and ultra-high-strength …

Characterizing A Potential Cbp/P300 Histone Acetyltransferase Homolog In Tardigrade Germline Specification And Development, Brittney Michelle Hartshorn

Honors Projects

Germline specification is a fundamental process that ensures the proper development of germ cells. Germline specification occurs either through germ cell determinants maternally inherited through the mechanism of preformation or through induction, where cell interaction and epigenetic modifications direct specification. Determining how these mechanisms evolved and diverged remains an important question in developmental biology. Despite research on germline regulation in model organisms such as Caenorhabditis elegans or Drosophila melanogaster, such regulation remains poorly understood in many other animal groups. Tardigrades are an emerging model system for investigating developmental mechanisms due to their phylogenetic placement and experimentally tractable embryos. CBP/P300 is …

Hybrid Densenet-U-Net Framework For Automated Grading Of Renal Cell Carcinoma, Rohini Jadhav, Banani Mohapatra, Bhavnish Walia, Sital Dash, Kailas Patil, Shrikant Jadhav, Ishwari Rohit Raskar

Faculty Research, Scholarly, and Creative Activity

Introduction: Precisely grading renal cell carcinoma (RCC) through histopathology slides is a requisite to predict the cancer prognosis and select treatments, however, there is a considerable variability in the assessment between observers. While some AI systems mainly rely on transformer-based and nuclei-centric models, they are computationally very demanding so their clinical use is thus limited. Hence, there is a need for practical and easy-to-understand solutions that can be integrated into digital pathology workflows. Methods: We built a hybrid framework that integrates U-Net-based tumor segmentation, convolutional feature extraction, nuclei-aware descriptors, stain normalization, and attention-based multiple instance learning for slide-level RCC grading. …

Performance was measured through both accuracy of correct responding and response latency across conditions. The participants of this study were recruited from Pittsburg State University and participated in a series of computerized tests while receiving various feedback types using a multielement design. The findings of this study aligned with some previous studies indicating the feedback types did not produce meaningful changes task performance in …

Mapping Homogeneous Configuration States For Learning Based Motion Planners, Yazied Hasan

Computer Science ETDs

Reinforcement learning (RL) excels at solving complex tasks, but training times can become prohibitively large for challenging motion-planning problems. Methods that address this cost often require additional training or tuning, counteracting the goal of reducing training time. A more effective approach is to exploit inherent task equivalences: many elements of the state space, dynamics, or structure are functionally interchangeable, enabling simplification or knowledge reuse. We present learning solutions that leverage these equivalences to enhance the RL process. First, we leverage the symmetry of homogeneous multi-agent teams to simplify the task to a single strategy. Second, we map correspondences between distinct …

From Sparse To Precise: Modeling Beam Profiles Using Wavelet-Based Implicit Neural Network (Winn) For Linear Accelerator Commissioning And Quality Assurance, Maryam Ali Albuainin

Computer Science ETDs

Commissioning and routine quality assurance (QA) in radiotherapy require extensive measurements using bulky water tank systems, making the process time-consuming and costly. This research proposes an efficient framework for radiotherapy commissioning and QA by generating complete LINAC physics data from sparse measurements and developing a portable solid-water detector with embedded diodes for high-resolution dosimetry.

At the core of the framework is a Wavelet-based Implicit Neural Network (WINN) that reconstructs full measurement datasets from limited inputs while maintaining clinical accuracy. The model achieves gamma passing rates above 95% (1%/1 mm) and mean absolute errors below 0.5%, while reducing parameters by 99.46% …

Computing Certificates Of Members In Archimedean Quadratic Modules In A[X] And Certifying The Emptiness In Inconsistent Monogenic Archimedean Quadratic Modules In A[X_1, ..., X_N], Jose A. Castellanos Joo

Computer Science ETDs

Polynomials have been found to be a powerful tool over hundreds of years for modeling problems in numerous applications in science, engineering, medicine, and other domains. In the context of formal methods, polynomials arise in modeling in aerospace software and robotics, cyber-physical and hybrid systems, autonomous vehicles and controllers based on neural networks.

A quadratic module is a linear combination of polynomials in a set of generators (including the constant 1) with sum of squares polynomials as multipliers. The membership problem for a finitely generated quadratic module can be decided; however, computing a certificate exhibiting why it is nonnegative under …

Where Is Home: Finding Belonging In God Through Expressive And Drama Therapy Processes Among Chinese Diaspora International Students, Minmin Pan

Expressive Therapies Theses

Being an international student for 12 years in the United States, this research engages with personal reflection and literature around international student identity formation situated in the current social and political context of increasing visa and employment uncertainty. International students’ ongoing movement across cultural spaces, limited representation of cross-cultural narratives and supportive spaces in academic settings, can contribute to fragmentation in experiences and identity that are shaped by dominant narratives and social positioning, thus further leading to disconnection from self and surroundings.

Relational spirituality literature suggests that one’s relational experience with God can deeply impact their interpretation of experiences, social …

What Is Mine, Yours And Ours: Bodily Metaphor And Neuropsychology, Alicia K.E Parham

Art Theses and Dissertations

Mapping the landscape of the brain has taken human lifetimes to navigate, both structurally to understand how our biological functions interact and functionally as our thoughts and emotions shape our existence. Neurological stimulus and response inform our reality, shape our thinking, and affect our bodies in profound physiological ways. Our nervous system acts as a bridge from what we experience physically to what we feel emotionally, through the sending of electrical signals to all parts of our body.

My art practice explores the interactions of neuroscience with outside stimuli. It is rooted in the personal: learning that a neurological condition …

Synecdoche: Archiving Violence In Schools, Jillian Whitney

Art Theses and Dissertations

K-12 Educators often find themselves thrust into a swamp of politics they never asked to enter. It is in this swamp that educators strive to meet students’ social, emotional, and educational needs. However, issues such as school shootings, racism, and gender inequality all make it difficult for schools to be what they should be: an equalizing, safe place where children can learn. These problems weaken the school system and harm public interest while leading to teacher burnout.

Synecdoche: Archiving Violence in Schools is a body of paintings and experimental artist books that responds to the everyday experiences of the educators …

Symbolists Beyond The Magic: Appropriation In The Art Of Elihu Vedder And Gustave Moreau, Rebecca B. Shalliker

Art & Art History ETDs

This thesis examines the paintings of Elihu Vedder and Gustave Moreau as examples of how the late nineteenth-century Symbolist movement drew on Eastern regions as aesthetic sources for representing the spiritual. Considering the iconographic and conceptual overlap with the Spiritualist movement, it explores how these groups contributed to constructing an image of the “East” as inherently mystical. While existing scholarship analyzes the Symbolist movement’s engagement with psychoanalytical concepts such as the subconscious and dream state, the role of cultural appropriation in shaping the Symbolist aesthetic has been largely overlooked.

The depiction of Eastern iconography as fantastical will be explored through …

The Effect Of Acute Hypoxia Exposure, With Exercise, On Bone Metabolic Biomarkers, Alyssa Bailly

Health, Exercise, and Sports Sciences ETDs

Hypoxic environments, resulting from decreased atmospheric partial pressure of oxygen, reduce oxygen availability in the blood and tissues, leading to a mismatch between supply and demand. This elicits several physiological adaptations and may influence bone metabolism. Although evidence suggests that hypoxia can modulate bone remodeling through hypoxia-inducible pathways, findings remain mixed, with most data derived from chronic hypoxic exposures in animal and cell culture models. Exercise, an essential stimulus for bone health, may exacerbate hypoxic stress; however, the skeletal response to acute hypoxic exposure combined with exercise remains unclear. We propose that intermittent exercise in hypoxia may increase negative markers …

Shaping Emergent Competitive And Cooperative Behaviors In Multi-Agent General-Sum Games, Ethan F. Erickson

Honors Projects

Reinforcement learning (RL) algorithms can train agents to solve problems in environments using complex behaviors that are not explicitly programmed, known as emergent behaviors. The goal of our research is to investigate how different RL reward values influence the emergence of competitive and cooperative behaviors in games with teams of multiple agents. Specifically, we focus on general-sum games, in which the sum of gains and losses of each team may be non-zero, allowing situations for agents to mutually benefit or mutually fail. Using Unity’s ML-Agents Toolkit to train agents with RL self-play in bounded 2D environments, we identify high-level behaviors …

Ab Initio Method Development For Electronic Structure Response And Symmetry Quantification, Duc Anh Lai

Chemistry Theses and Dissertations

Electronic structure provides a fundamental framework for understanding molecular properties and reactivity, as it encodes the spatial distribution of electrons and their response to external and internal perturbations. This dissertation develops theoretical and computational frameworks to characterize and manipulate electronic structure through two complementary directions: the response to oriented external electric fields and the quantification of symmetry regulation in electron density.

First, a rigorous theoretical and computational framework is established for treating electric fields with arbitrary orientations relative to molecular structure. The concept of the rotational potential energy surface is introduced to characterize the dependence of molecular energy on field …

Beyond Brain Drain: H-1b Visas, Innovation, And Human Flourishing, Joel Wong

Honors Projects

High-skilled migration has become one of the defining features of the modern global economy, especially in technology, engineering, and research-intensive industries. While public debate surrounding the H-1B visa program often centers on its effects within the United States, less attention has been given to how these migration flows affect the countries from which workers originate. This question is important because many sending countries invest heavily in the education and development of highly skilled workers while also seeking long-term economic growth and innovation. This study examines whether increases in H-1B visa migration are associated with changes in innovation outcomes in major …

Fluid Identities: Using Seattle's Diverse Water Narratives To Shape Cultural Values And Adaptive Conservation Strategies, Brooke J. Vanden Berg

Honors Projects

This paper explores human interactions with the environment in and around Seattle, Washington, following its trajectory from the Vashon glacial episode to its present standing as a city on the frontier of future urban climate resilience. By examining the shift from indigenous stewardship to a twentieth-century settler-led industrial “taming” paradigm, ecological vulnerabilities are considered through the lens of ill-advised hydraulic regrading and the centralization and privatization of water infrastructure and rights. This history is contextualized in the 21st century as climate projections indicate that Seattle's reliance on mountain snowpack, increasing thermal extremes, sea-level rise, and hydraulic instability caused by climate …
