Hiding In Plain Sight, Evan Seeling

Theses

This thesis considers how perceptual, emotional, and behavioral patterns—often inherited, unnoticed, or obscured—can be revealed through the optical phenomena of glass. It connects visual experience with themes of grief, memory, and identity, using glass to explore the boundary between what is seen and what is felt. Through material investigations in refraction, reflection, and spatial arrangement, the studio research examines how glass can both obscure and reveal, echoing the instability of perception itself. These investigations, paired with a focus on viewer interaction, suggest that patterns hiding in plain sight become visible through intentional acts of perception and reflection.

Understanding Behavioral Patterns: A Case Study Of Emirati Ex-Offenders In United Arab Emirates, Salim Ali Al Naqbi

Theses

Research on desistance has helped criminologists to better understand how people change their criminal identity and exercise personal choice. Yet in the UAE, these ideas has not often been applied to prisoners serving one or multiple offenses, even though incarceration and reoffending remain important social concerns. Because of this, desistance theory has not been fully used to study how rehabilitation is managed in UAE prisons, which means that some useful lessons may be missed. This study begins to close that gap by looking at the personal stories of 15 Emirati participants that were formerly incarcerated by adapting a qualitative and …

The Mystical Kitchen: Feminist Magic And Alchemical Transformation In The Work Of Lenora Carrington, Theresa Burwell

Theses

This thesis analyzes the inherent feminism in alchemical and magical symbolism, particularly in representations of kitchens in the art and writing of Leonora Carrington. The kitchen has historically been viewed as a gendered space for domestic work. By subverting cultural and religious conventions, Carrington’s kitchen becomes a site for transmutation and feminine ritual. Using feminist discourse, formal art historical analysis, and the history of alchemical symbolism, this thesis asserts that Carrington’s imagery transforms the kitchen from an oppressive domestic space to a mystical laboratory of feminine power. A thorough analysis of Grandmother Moorhead’s Aromatic Kitchen (1975) and The House Opposite …

Democratizing Community Discourse Analysis In Computational Social Science, Md Towhidul Absar Chowdhury

Theses

Community resource inequities and undetected infrastructure vulnerabilities cost municipalities billions annually, with disproportionate impacts on marginalized communities. Current computational approaches to community needs assessment suffer from two critical limitations: they rely on aggregate-level analysis that obscures granular community expressions, and they implement sophisticated computational tools that remain inaccessible to stakeholders without technical expertise. This creates what we term the Community-Computational Gap—a persistent divide where domain experts with vital contextual knowledge cannot access the analytical tools they need, while computational experts develop models without sufficient community context. This dissertation addresses these challenges through a novel methodological framework for fine-grained utterance-level classification …

People’S Plate: The Recipe For Equitable Food Distribution, Bayleigh Nicole Thurston

Theses

Food insecurity remains a pressing issue in the United States that disproportionately affects vulnerable populations, leaving millions without access to nutritious meals. In 2023 alone, over 50 million people turned to food assistance programs for additional support1. While traditional nutrition programs like food banks and soup kitchens provide a vital service to many communities, they often lack the capacity to address the multifaceted nature of hunger. The social stigma and alienation associated with seeking food assistance become of little concern when organizations are grappling with daunting challenges of limited resources, logistical hurdles, and the need to provide quality, nutritious meals. …

Cognitive Reserve In The Deaf/Hard Of Hearing Community: An Exploration Of Contributing Factors, Olivia B. Allaby

Theses

Cognitive reserve (CR) refers to the individual differences in how people execute tasks, allowing some to cope with cognitive challenges more effectively than others. Additionally, previous studies have established a link between age-related hearing loss and cognitive decline. However, CR and cognitive aging have not been explored extensively in those who might identify as Deaf/hard of hearing (HH). There are four features potentially unique to this community that could shape one’s CR: use of hearing technology (e.g., hearing aid), bimodal bilingualism, and social connectedness and social support. One hundred fifty-nine Deaf/hard of hearing participants completed an online survey study assessing …

Enhancing Adversarial Robustness In Convolutional Neural Networks By Integrating Human Viewing Strategies, Diana Velychko

Theses

Adversarial examples pose a serious threat to the reliability of deep neural networks by subtly manipulating inputs to induce incorrect outputs. Despite progress in the field, convolutional neural networks (CNNs) remain vulnerable to such perturbations. This research proposes a novel approach to improve adversarial robustness of CNNs by incorporating human viewing behavior into both training and testing processes. To establish a baseline for comparison with models trained from scratch, an eye-tracking dataset—collected during experiments involving novel objects from the Greeble dataset—was used to capture how humans learn to classify previously unseen object categories.

Dyadic And Multiparty Turn-Taking In Two Deaf Preschool Classrooms, Savannah Tellander

Theses

Conversational turn-taking skills are needed to succeed in most conversational interactions. Timing of turn-taking is crucial for young deaf signers, who need early, accessible, and consistent input in a signed and/or spoken language. For deaf children who acquire a language in either modality, they must acquire appropriate turn-taking skills. Without these abilities, children may miss critical language input, and in a cascading effect–they may miss opportunities both for input (and thus new knowledge) and expressive language. In addition to documenting deaf children’s turn-taking skills across development, it is important to also document timing data for further understanding of cognitive language …
