Pattern-Aware Graph Neural Networks For Handling Missing Data, Minett Tran, Taehee Jeong

Faculty Research, Scholarly, and Creative Activity

Missing data is ubiquitous in real-world datasets. Traditional methods either discard incomplete samples or apply imputation techniques that ignore potentially informative missingness patterns, implicitly assuming that missingness occurs randomly. However, missingness patterns might provide additional information. We propose pattern-aware graph neural networks that explicitly encode which features are missing alongside observed values. We used four encoding strategies-learned embeddings, frozen random embeddings, statistical features, and hierarchical representations-across seven UCI datasets with naturally occurring missingness. Our Pattern-aware methods achieve substantial improvements over baselines, with an average improvement of 17% in balanced accuracy and 22% in F1-macro across all datasets. Our code and …

Phenomenological Philosophy Of Psychedelics: Psychedelic Experience In The Modes Of Saturation And Flesh, Michael V. Kramer

Electronic Theses and Dissertations

This work seeks to develop the nascent sub-field of the phenomenological philosophy of psychedelics. Beginning with a general overview of key aspects pertinent to psychedelic studies, the focus then turns to a general disciplinary discussion of current approaches within the philosophy of psychedelics, as well as psychedelic philosophy—a distinction which is technically deployed. Special consideration is given to the specific approach known as the “natural philosophy of psychedelics,” which is taken as the philosophical foil to the preferred approach of phenomenological philosophy. A survey of the extant literature regarding the implementation of phenomenology within psychedelic discourse is then provided …

All Decisions

In this breach of lease holdover, petitioner alleged that respondent breached her lease by committing a nuisance. The court grants respondent's motion to dismiss, finding the allegations insufficient as a matter of law: the breach of lease allegations did not specify which term of the lease was breached, nor did they specify any dates or times for the alleged conduct.

Road To Brexit: History Of Euroscepticism In The United Kingdom, Jake M. Flowers

2026 Spring Honors Capstones Projects

Scholars in recent years have attempted to understand why citizens of the United Kingdom voted to leave the European Union in 2016, with many taking interest in the history of Euroscepticism in the country. Previous research on the topic has considered the impacts of geopolitical trends after World War II, Eurosceptical political activity in the 1980s, and longer-term historical attitudes. This paper examines the long history of Brexit to consider these events as a whole instead of as separate parts. As this is a history research project, the primary methodology is an analysis of speeches and primary sources from across …

Systematic Reviews Across Disciplines: Comparing Quality And Publication Practices, Megan Bresnahan, Eugenia Opuda

Faculty Publications

As the publication of systematic reviews has proliferated across the sciences in the past decade, librarians have a role in helping researchers select the appropriate type of review, providing best practice guidelines, and under-standing variations in disciplinary practices for evidence synthesis. Using a title-abstract search filtered by 10 research areas in the Web of Science, we collected a sample of 100 systematic reviews from a range of disciplines, including “Fisheries,” “Forestry,” “Health Care Sciences & Services,” and “Veterinary Sciences.” Our analysis of this data explores to what extent these articles include the basic components of a systematic review and adhere …

Statistical Cryogenic Characterization Of Commercial 14nm Finfets For Analog Applications, Wesley Xi, Le Minh Long Nguyen, Vikram Magendar, Hiu Yung Wong

Faculty Research, Scholarly, and Creative Activity

Cryogenic devices at 4.2K are indispensable in the control electronics for large-scale quantum computers. Due to its small manufacturing volume, a standard commercial foundry process is likely to be used in the near and medium terms. Moreover, 77K electronics are promising for high-speed server applications. Besides digital circuits, analog circuits with non-minimal channel length are particularly important in quantum computing control. In this paper, special structures are designed to characterize the device properties of medium- and long-channel length devices at 292K, 77K, and 4.2K in a commercial 14nm FinFET process. About 100 structures were measured for both NMOS and PMOS. …

Multi-Resolution Feature Stem For Diabetic Retinopathy Lesion Segmentation, Indranil Dutta, Taehee Jeong

Faculty Research, Scholarly, and Creative Activity

Diabetic Retinopathy (DR) is a leading cause of preventable blindness worldwide, requiring automated lesion segmentation using deep learning models for early detection and monitoring. However, DR lesions vary dramatically in size from tiny microaneurysms to large hemorrhages and exudates. This variability creates conflicting demands on the model architecture and input resolution, posing a challenge for effective design. This work investigates the impact of input resolution on different lesion types. Through systematic experimentation with multiple architectures (U-Net, UNet++, Vision Transformers, DeepLabV3+) at 512 × 512 and 1024 × 1024 resolutions, we identify a critical, counter-intuitive phenomenon where increasing input resolution has …

Leadership Styles And Information Security Policy Compliance Intentions: The Mediating Role Of Psychological Empowerment, David Sikolia, Andy Luse

Faculty Submissions

This study extends prior research on psychological empowerment and information security policy (ISP) compliance by examining whether transformational and transactional leadership influence employees' compliance intentions indirectly through psychological empowerment.

Data were collected from a convenience sample of 119 employed individuals enrolled in a US MBA program. The model was estimated using partial least squares structural equation modeling (PLS-SEM). Psychological empowerment was modeled as a second-order construct comprising meaning, competence, self-determination, and impact. Indirect effects were assessed with 5,000 bootstrap resamples and 95% bootstrap confidence intervals.

Both transformational and transactional leadership were positively associated with psychological empowerment, and psychological empowerment strongly …

Lineup Construction Strategies In The Presence Of Within-Person Variability, Abbey M. Greenfield

Student Theses

Photographic lineups are used more frequently than live lineups, but photographs are not always reliable representations of a person’s appearance. Oftentimes, images used in lineups are drawn from mug books, passports, and driver’s license photographs—which may be outdated. As a result, even when a culprit is correctly identified for inclusion in a lineup, the photograph used may differ significantly from their appearance during the event due to natural changes in appearance (Jenkins et al., 2011). Further, the degree of suspect-filler similarity sufficient to achieve optimal discriminability remains a topic of debate (Fitzgerald et al., 2013). We examined the impact differing …

Trauma, Memory, And Decision-Making: How Covid-19 Shaped Autobiographical Memories And Risky Decision-Making In Young Adults, Rachel Seo

Student Theses

Autobiographical memory is a critical component of the memory process that guides future behaviors by relying on past personal experiences connected to major public events. This decision-making process is heavily influenced by trauma exposure and post-traumatic stress disorder (PTSD) symptoms, as they may guide individuals to riskier behaviors. The COVID-19 pandemic represents a global traumatic stressor that contributed to shifts in behavioral outcomes post-pandemic. Despite research showing associations between memory accessibility, traumatic symptoms, and decision-making, there is limited research on health-related behaviors and post-pandemic behavioral outcomes in individuals with high trauma exposure specifically from the pandemic. The present study investigates …

Somewhere Between Tool And Teammate:A Construct-Level Framework For Ai-Assisted Coding Reliability, Amanda N. Moeller, Abi K. Leyden, Joey Welles, Isaac J. Moelter, Erin E. Johnson, Samuel Hunter, Gina Scott Ligon

Reports, Projects, and Research

Federal Artificial Intelligence (AI) initiatives have increasingly emphasized accelerating AI adoption across government operations while maintaining appropriate governance and oversight mechanisms (Office of Management and Budget [OMB], 2025; The White House, 2025). AI systems are increasingly being integrated into research and operational workflows to support the large-scale analysis of unstructured information. Across high-impact environments, AI-enabled systems are being used to accelerate document review, organize information repositories, extract structured indicators, and support operational and analytic decisionmaking. However, despite rapid adoption, many organizations still lack practical frameworks for determining when AI-generated outputs are sufficiently reliable to support operational use and when human …

The Priene Synagogue Community And Jewish Diaspora Prominence In Late Antique Cities, Amari Pavati

Undergraduate Honors Theses

The late antique synagogue of Priene, like other synagogues in the region and potentially beyond, acted as an “urban center” for the community it served. I argue that the urban context of diaspora synagogues like the Priene synagogue has been under explored, and that analysis of Jewish communities within their changing urban contexts reveals the place of Jewish communities within late antique society. Synagogues served multiple functions for their communities, some visible from archaeological evidence and other known from textual evidence. The Priene synagogue, for example, was laid out and artistically decorated to mark the central, sacred nave as separate …

Seasonal Variation And Size Distribution Of Particulate Matter In The Mississippi Delta: Implications For Source Attribution, Abigail E. Barnett

Honors Theses

This study examines seasonal patterns of particulate matter in the Mississippi Delta using data from PurpleAir sensors, with a focus on particle size distributions across PM₁.₀, PM₂.₅, and PM₁₀. The purpose of this research is to evaluate whether particulate trends in the region reflect signatures consistent with wildfire smoke or are better explained by local environmental and agricultural factors.

Daily average concentrations were analyzed and grouped by season to compare spring and summer conditions. Results show that all particle size fractions increased from spring to summer. However, PM₁₀ concentrations remained consistently higher than PM₂.₅ in both seasons. The PM₂.₅/PM₁₀ ratio …

A Remote Sensing Approach To Identifying Zones Of Instability In Mine Tailings Impoundments Using Multi-Sensor Satellite Data, Arden K. Pierce

Honors Theses

Mine tailings impoundments are structures built to contain the chemical and sedimentary byproducts generated by ore extraction activities. In this common method of mining waste storage, the tailings can be pumped into containment ponds and held behind earthen embankments to prevent the release of hazardous substances into the surrounding environment. Monitoring environmental factors that influence the structural integrity of these impoundments is essential for identifying areas vulnerable to instability and failure. Soil moisture is a factor that can affect the stability of mine tailings impoundment structures. This study evaluates the relationship between satellite-derived soil moisture and surface deformation at mine …

Quantifying Genetic Diversity In Nematode Feeding Rate, Jacob King

Honors Theses

Understanding how populations persist under changing environmental conditions is a central question in ecology and evolutionary biology. Variation in traits related to resource acquisition may play a key role in determining population survival when resources are limited or fluctuate over time. In this study, I investigated how variation in feeding-related traits influences population persistence using a combination of computational modeling and laboratory experiments. I developed a stochastic, individual-based consumer–resource model to simulate population dynamics across varying levels of trait variance and resource regimes. Across 60,000 simulated populations, increased trait variation consistently reduced extinction risk and extended persistence time, although the …

The Effects Of Mississippi Mandated Testing On Students And Teachers, Christopher I. Goss

Honors Theses

This thesis concerns the direct impacts of the Mississippi mandated standardized testing, used for graduation, on Mississippi public school teachers and students. To collect appropriate data, I used the Qualtrics survey platform to fit in the parameters needed for IRB approval. This survey provided individuals an opportunity to express their opinions on certain statements, ideas, and beliefs about the current mandated standardized testing system, while also collecting background information for comparing data such as differences between how much someone from a D ranked school would support standardized testing compared to someone from an A ranked school. Most teachers and faculty …

Lunar Manufacturing Systems And The Role Of Additive Recycling Technologies, Camille A. Newman

Honors Theses

Renewed international interest in sustained lunar exploration has created a growing demand for technologies to support long-duration space exploration. Part of the recent Artemis missions and the Moon to Mars initiative is to improve key mission capabilities and fill critical gaps necessary to sustain lunar habitation. Waste management, recycling systems, and manufacturing systems have been identified as critical technologies that need further development before a sustained mission is possible. This thesis explores the feasibility of an additive manufacturing and recycling system designed to process plastic waste generated during extended lunar habitation. Initial research focused on existing manufacturing and recycling technologies …
