Towards A Multi-Framework Approach To Explainable Artificial Intelligence, Henry Salgado

Open Access Theses & Dissertations

Artificial Intelligence (AI) and machine learning (ML) models are increasingly being deployed to support decision-making in high-stakes domains such as healthcare, criminal justice, and education, where trust, accountability, and transparency are critical. However, increasing model complexity has made many modern systems insufficiently transparent. Existing approaches to explainable AI (XAI) typically emphasize either intrinsic model simplicity or post-hoc attribution methods that estimate feature importance for predictions. While these approaches provide valuable insights into model behavior, they do not necessarily establish whether the identified importance is grounded in the underlying data patterns or in the structural relationships that generate model behavior. Many …

Mija, Yes You Can: Faith And Motherhood In The Making Of A Scholar, Alejandra Salgado-Hernandez

Open Access Theses & Dissertations

This autoethnographic study examines how motherhood, faith, and borderlands identity shaped persistence throughout my journey as a Chicana mother-scholar in the U.S.-Mexico borderlands. Grounded in Borderlands Theory and Chicana Feminist Epistemology, the study centers lived experience, testimonio, spirituality, emotion, and embodied knowledge as legitimate forms of inquiry. Data included reflective journals, personal memory work, and selected family contributions. Through iterative narrative and thematic analysis, I organized experiences chronologically, coded recurring patterns and critical incidents, tested candidate themes across sources, and interpreted the resulting themes through the study's theoretical and scholarly literature. Four interconnected themes emerged: living in nepantla through borderlands …

Behavioral And Dietary Associations Of Vitamin D Deficiency Among Landscaping Workers: An Analytical Cross-Sectional Study In El Paso, Texas., Cristela Anahi Avila

Open Access Theses & Dissertations

Background: Vitamin D deficiency is a persistent public health concern, even among outdoor workers who receive substantial sunlight exposure. Landscaping workers may still be at risk because sun-protective clothing, early work hours, behavioral practices, and low dietary intake can reduce effective vitamin D synthesis. Purpose: This pilot study examined dietary vitamin D intake, sun exposure behaviors, and serum 25-hydroxyvitamin D status among male landscaping workers in El Paso, Texas, to identify behavioral and nutritional factors associated with deficiency. Methods: Twenty participants completed a culturally adapted food frequency questionnaire and behavioral assessment and underwent capillary point-of-care testing for serum 25(OH)D. Descriptive …

Daily Consumer Expenditures And Income: New Evidence From A Payment Diary, Shaun Gilyard, Scott Schuh

Economics Faculty Working Papers Series

This paper demonstrates that unique daily consumption and income transactions data derived from the Diary of Consumer Payment Choice (DCPC) produced unplanned benefits: they cover high percentages of U.S. data, forecast well in real time, offer new insights to payday and pay-cycle effects, and suggest selection effects in convenience samples of transactions data. Relative to other transactions data, DCPC data are more representative, publicly available, and offers other advantages. Daily data more clearly exhibit three explicit features largely absent from lower frequencies: 1) discrepancy between consumption and expenditures; 2) discrete expenditures and income; and 3) asynchronous consumer expenditures (daily) and …

Quantitative and qualitative data were collected to explore the questions posed. Quantitative data included usage reports from GALILEO and descriptive statistics. Qualitative data were coded to determine themes and opinions of faculty/students. Quantitative reports showed the databases students prefer and how they prefer to use them. The qualitative findings showed that faculty may not …

An Exploration Of The Psychological Impacts Of Code-Switching, Cristina Culler

Electronic Theses and Dissertations

This dissertation is an interpretative phenomenological analysis of the lived experiences of four Black American adults who have frequently engaged in code-switching. Historically, code-switching has been perceived as a necessary skill that helps marginalized folx adopt the norms and practices of the dominant culture. As a result, code-switching has become a routine practice specifically for Black Americans who often occupy white spaces. Since code-switching has been perceived as a skill, the oppressive origins of code-switching often go unnoticed. Therefore, this dissertation examines code-switching through a critical lens that deems this practice a product of racist ideologies that prioritize whiteness. Through …

Development And Evaluation Of Alternative Mandrel Materials For The Fabrication Of In-House Silicone Vascular Models, Cole Capitani

Master's Theses

Dr. Kristen Cardinal’s Tissue Engineering Laboratory at California Polytechnic State University, San Luis Obispo develops tissue-engineered blood vessel mimics (BVMs) for preclinical testing of neurovascular devices. These BVMs are reliant on silicone vascular models that define the vessel geometry, support endothelial cell attachment, and allow devices to be evaluated in a controlled in vitro environment. Previous work in the lab established injection molding as a viable method for fabricating silicone vascular models and utilized acrylonitrile butadiene styrene (ABS) for sacrificial mandrels. However, this workflow relied on the use of acetone for mandrel dissolution, required single-use mandrels, had extended post-processing times, …

When Does Emigration Reduce Domestic Economic Activities? Evidence On The Loss Of Management Capacity From A Visa Lottery, Marup Hossain, Ahmed Mushfiq Mobarak

Discussion Papers

Economic development is often conceived as structural transformation and migration out of rural agriculture (Lewis, 1954; Fei & Ranis, 1964). Understanding development therefore requires us to identify how rural economies transform in response to emigration. We study how international migration reshapes domestic economic activity in origin households using a randomized visa lottery that gave Bangladeshi men job opportunities in Malaysia. Winning the lottery raises total household income through remittances, but income earned in Bangladesh declines due to contractions in nonfarm business activity. In contrast, crop income remains stable despite large reductions in agricultural input expenditures, because farming gets delegated through …

The Information Content Of The Implied Volatility Term Structure Slope For Forecasting Commodity Market Volatility, Lawrence E. Mckenzie

Doctoral Dissertations (DBA)

This study evaluates the implied volatility term structure (IVTS) slope (𝜅) for forecasting 21-day realized volatility against traditional time-series benchmarks and a 3-month continuous futures baseline. Using a matched sample of eight energy and agricultural commodities spanning 2007 to 2019, the study explicitly tests whether the option-implied slope contains unique predictive information beyond deferred price histories. The empirical findings yield three primary insights. First, redundancy testing indicates that the slope parameter delivers a statistically significant, independent risk signal even when controlling for deferred continuous futures paths. Second, an integrated joint encompassing framework that combines near-term historical volatility, generalized autoregressive conditional …

Mission Parkinson Possible: Building Confidence In Parkinson’S Disease Care In Skilled Nursing, Theresa Tran

Master's Projects and Capstones

Objective: Parkinson’s disease (PD) is a progressive neurological disease that requires specialized, interdisciplinary care. Despite this, staff in the skilled nursing setting often receive limited PD-specific education. This contributes to inconsistencies in care, improper medication administration, and reduced confidence in disease management. Aim: This project aimed to improve staff self-reported confidence, competence, and workflow in Parkinson’s disease care and disease management by 15%, from a baseline of 60% to 75%. Methods: The project implemented a PD-specific educational program that consists of an hour-long PowerPoint presentation and distribution of physical brochures to staff, residents, and their families. Pre- and post-surveys were …

The Effect Of Childcare On Female Labor Supply And Child Development In Low And Middle Income Countries, Serena Goldberg, Costas Meghir

Discussion Papers

Childcare services can offer an opportunity for women to develop their careers and increase household income. At the same time, it can affect the development of children, depending on the quality of care. We first develop a collective model of the household as a conceptual framework to show how improving the availability of childcare can affect mothers’ labor market opportunities and earnings and how it can affect child development. We then review the literature on the effects of childcare on the employment and earnings of women and on child development. Childcare can increase mothers’ employment. However, limited work opportunities or …

Secure And Compassionate Dementia Care: Non-Intrusive Remote Monitoring Of Falls, Wandering, And Agitation, Awan-Ur- Rahman

Master's Theses

Alzheimer’s disease and related dementias (ADRD) present significant safety challenges, as affected individuals may experience falls, wandering, agitation, and a progressive decline in independence. Although continuous monitoring can enable timely intervention, many existing systems rely on cameras or wearable devices, which may introduce concerns related to privacy, comfort, and sustained use. This thesis explores privacy-preserving and non-intrusive remote monitoring through two complementary studies. The first study presents an ambient Wi-Fi channel state information framework for recognizing agitation and eight daily activities. The proposed approach translates behavioral and physiological markers commonly captured by wearable sensors into the Wi-Fi sensing domain. The …

Pseudo-Riesz Bases, Deborpita Biswas

All Dissertations

In this dissertation, we will introduce the concept of pseudo-Riesz bases, extending the influential notion of near-Riesz bases first proposed by J. Holub in the 1990s. Our goal is to develop an analogous theory for pseudo-Riesz bases, obtaining results parallel to those known for near-Riesz bases, with suitable modifications.

We will develop the foundational theory of pseudo-Riesz bases. Unlike classical Riesz bases, these sequences need not be complete or independent; however, they still retain meaningful expansion properties. We will investigate the conditions under which a Bessel sequence can be transformed into a Riesz basis through finite modifications. In particular, we …

Exploring Public Perceptions Of Genetic Risk In Substance Use Disorders, Brooke A. Goodenow

All Dissertations

This dissertation examines genetic risk perception, with specific emphasis on substance use disorders (SUDs), through a collection of three manuscripts. The dissertation examines genetic risk perception for hereditary diseases in existing literature, describes a methodological framework for capturing genetic risk perception across social media discourse, and identifies themes and emotional tone associated with genetic risk perception for SUDs across two major social media platforms (X and Reddit).

Combined, these three manuscripts expand and support previous findings about genetic risk perception and its role in shaping health beliefs and associated behaviors. The dissertation findings reveal numerous similarities in genetic risk perception …

Student Motivation In Social Studies Classes At The Public Museum High School: A Dissertation, Benjamin Kruid

All Dissertations

Students tend to behave differently in different classroom settings. Many factors contribute to the change in behavior, including motivation. Research suggests a tendency for student motivation to decrease as students move from elementary to middle to high school. However, motivation in students is not uniform and is dependent on factors like the subject, and time of day, for example. This dissertation examines student motivation in social studies classes at a public high school in Michigan using Situated Expectancy-Value Theory (SEVT) as a framework for understanding motivation, and student impulsiveness as understood through the lens of Delay Discounting (DD). This research …

When Your Neighbours Are A Reminder Of Your Ageing, Cynthia Tan, Yi Wen (Chen Yiwen) Tan

ROSA Journal Articles and Publications

In a commentary, Cynthia Tan, a retired senior corporate leader, and Tan Yi Wen, a Senior Research Fellow at SMU’s Centre for Research on Successful Ageing (ROSA), questioned whether the low demand for community care apartments is because seniors do not want only other seniors for company. They noted that most older people do not spend their days dwelling on ageing until everyone around them reminds them that they are growing old. They added that prolonged exposure to such an environment may carry subtle emotional and psychological consequences. Citing a national survey by ROSA, the writers mentioned that eight in …

Causal Discovery Methods For Single Cell Rna-Seq Data, Melanie Lambert

All Dissertations

The advancement of single cell RNA sequencing (scRNA-seq) has enabled the study of causal relationships between genes at single cell resolution. Although many causal discovery methods have been applied to scRNA-seq perturbation data, they are not well-suited to capture the characteristics of scRNA-seq data. The overall goal of this dissertation is to enhance researchers' ability to gain insight into genetic relationships.

The scRNA-seq data is high-dimensional, typically containing thousands of genes, and is sparse and zero-inflated due to dropout events, as well as noisy and subject to biological variability. Traditional causal discovery methods, such as constraint or score-based approaches, do …

Distributed Coordination And Optimization Of Utility-Scale Battery Energy Storage Systems Via Multi-Agent Reinforcement Learning, Parthiv Debnath

All Theses

The increasing integration of renewable energies into modern power systems has created significant operational challenges, including transmission congestion, renewable energy curtailment, and increased real-time supply-demand variability, which makes effective coordination and optimization of multiple distributed Battery Energy Storage Systems (BESS) across power systems a critical problem, a useful solution, yet an unresolved challenge. Existing centralized optimization methods require perfect future information and are incompatible with the confidentiality constraints of deregulated electricity markets, while rule-based approaches fail to capture the multi-objective complexity of real-world power grid operations. This thesis proposed a Multi-Agent Proximal Policy Optimization (MAPPO) framework with Centralized Training and …

Scope: Deep Learning-Based Side-Channel Evaluation Across Classical And Post-Quantum Cryptographic Implementations, Nouf Nur Nabilah

All Theses

A cryptographic algorithm that is mathematically secure can still be broken since its hardware implementation leaks secret information through power consumption or electromagnetic emissions. These vulnerabilities are applicable to widely deployed classical encryption schemes as well as emerging post-quantum schemes which are standardized to provide quantum resistance. This thesis evaluated how deep learning changes such side-channel attacks across both through a unified study of four attacks, spanning a classical block cipher and two protected post-quantum schemes, and tested learned methods against the conditions that separated a laboratory result from a practical attack. Profiled deep-learning attacks recovered keys efficiently under favorable …

Llm-Assisted Task-Adaptive Semantic Communication Over Non-Ideal Channels For Vision–Language Systems, Oluwagbenga Oluwapelumi Orimoogunje

All Theses

The growth of intelligent wireless systems and bandwidth-limited edge devices has created a need for communication methods that move beyond bit-level data transmission. Semantic communication addresses this by transmitting task-relevant meaning, which reduces bandwidth usage while preserving task performance. However, existing approaches often rely on frozen encoders without task feedback and are trained under fixed or ideal signal-to-noise ratio (SNR) conditions. These limitations lead to poor generalization in realistic noisy channels.

This thesis proposed a task-adaptive semantic communication framework for Visual Question Answering (VQA) over bandwidth-constrained Additive White Gaussian Noise (AWGN) channels. The system transmits a compact 16,384-dimensional semantic feature …
