The Symphony Of Justice: An Intertextual Study Of Social Justice Material Between The Torah And The Psalms, Daniel Gordan

Dissertations

Do passages dealing with social justice in the Torah and the Psalms together comprise an intentionally composed grand symphony, or do they merely form an ad hoc patchwork quilt in which their echoes of similarity are mere coincidences?1 Literary interactions between the Torah and the Prophets of the Hebrew Bible have been a focus of biblical scholarship, but the intertextual connections between the legal corpus of the Torah and poetry in Psalms have not received sufficient attention. Scholars have noticed some thematic similarities, but there are no systematic studies that analyze these interactions to determine whether they involve reuse and, …

Human Perceptions Of Social Intelligence In Large Language Models, Derek Koehl

Dissertations

This dissertation investigates how users form perceptions of social intelligence and trust when interacting with large language model chatbots. Three experimental studies manipulated chatbot agreeableness, goal orientation, and simulated short-term memory, measuring perceived social intelligence and trust. The primary finding is an asymmetric effect of personality: disagreeable chatbot behavior produced large reductions in perceived social intelligence and trust, whereas agreeable behavior produced negligible gains above a warm baseline, consistent with negativity bias in social cognition. Goal orientation did not independently enhance perceptions but functioned as a contextual moderator. Simulated memory produced medium-to-large increases in perceived social intelligence without reliably increasing …

Quantitative Metabolomics And ¹³C-Enrichment Analysis Of The Effects Of Fat10 Overexpression On Serum And Hepatocytes, Emily C. Hunt

Dissertations

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease, is associated with obesity and type 2 diabetes, and as the prevalence of these conditions increases, the incidence of MASLD is expected to rise. However, the mechanisms that underlie the development of MASLD are complex and incompletely understood. Previous work from our group has indicated that the human leukocyte antigen-F adjacent transcript (Fat10) is overexpressed in the LEW.1WR1 rat model, which develops features of MASLD. The objective of this work was to quantify metabolites associated with MASLD in response to Fat10 overexpression. To achieve this end, we …

Sharing Patient-Generated Health Data With Electronic Health Record: A Standardised Provenance And Context-Rich Information Model And Clinician Evaluation, Abdullahi Abubakar Kawu

Dissertations

With the advent of Patient-Generated Health Data (PGHD) through wearable, mobile, and home monitoring systems, there is immense potential for ongoing monitoring and patient engagement. But integrating PGHD with Electronic Health Record (EHR) is challenged by sub-optimal support for contextual metadata and its relevant elements, lack of semantic interoperability among disparate systems, poor knowledge regarding the factors that impact clinician acceptance, and absence of globally agreed standards for data exchange.

A Qualitative Case Study Exploring The Processes And Criteria For Presidential Leadership Selection In Three United States Higher Institutions Of Learning, Gabriel Kofi Boahen Nsiah

Dissertations

Background of the Problem

Today, research on U.S. higher education presidential search processes is limited, and existing literature characterizes these searches as reactive postures that are secretive, closed-door practices that have not adapted to the early signals of external seismic change. According to Quincy Martin (2021), “the world has evolved (p. 99).” Therein lies the problem. Quincy Martin insists, “Higher education has entered a period of upheaval, aided by new technologies, but hampered by political and cultural shifts. These are only amplified by modern, warp-speed information-sharing practices. All of this has exacerbated the consequences of scandals that threaten the stability …

Semi-Supervised Learning For Annotation And Representation Of Single-Cell Rna Sequencing And Spatial Transcriptomics Data, Haoran Liu

Dissertations

Semi-supervised learning has emerged as a powerful paradigm for analyzing single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) data, where full annotation is often costly or impractical. scRNA-seq technologies measure the expression of thousands of genes across tens of thousands of cells, whereas ST additionally captures the spatial coordinates of gene expression within intact tissue sections. Annotation is a key step in both scRNA-seq and ST analysis pipelines, aiming to identify cell types, spatial domains, and latent biological structures. However, most existing annotation approaches rely on separate clustering methods that are typically fully unsupervised and fail to leverage side information …

Beyond Words: A Systematic Multimodal Framework For Text, Images, And Extreme Helpfulness In Online Reviews, Alvaro J. Aguado Marin

Dissertations

Online product reviews have become increasingly multimodal, combining text with media-rich elements such as images. However, academic research has largely examined textual features in isolation, overlooking how visual content and its interaction with text shape perceived helpfulness. This dissertation addresses that gap by developing and empirically validating a comprehensive framework capturing how textual, visual, and contextual features collectively influence review evaluation. Grounded in the Elaboration Likelihood Model (ELM) and extended through the Text-Image Elaboration Likelihood Model (TI-ELM), the framework advances understanding of how consumers process content from both user- and business-generated sources. It also lays the foundation for examining emerging …

Computational Design Of Nanoporous Materials For The Adsorption Of Per- And Polyfluoroalkyl Substances, Daniel D. Mottern

Dissertations

Per- and polyfluoroalkyl substances (PFAS) are a large family of chemicals that have seen wide usage due to their fluorinated carbon backbone. The presence of strong C-F bonds in the backbone lends PFAS molecules high thermal and chemical stability, as well as strong hydrophobicity and lipophobicity. This combination of properties has led to heavy use of PFAS as surfactants, non-stick coatings, and aqueous foam forming films and flame retardants. However, these properties bring their own consequences. The high chemical and thermal stability of PFAS renders them persistent, with the C-F bonds resisting naturally occurring forms of degradation. Existing forms of …
