Emotion Analysis And Neural Language Models For Classification, Andrew Mackey

Graduate Theses and Dissertations

Emotion analysis is a branch of artificial intelligence and natural language processing focused on recognizing emotions hidden throughout various forms of digital data, including text, images, and multi-modal representations. In this dissertation, we present four published and planned works that investigate different methodologies for natural language analysis tasks using deep learning techniques. The first published work we present considers the task of identifying fake news using various text and emotion representations. We demonstrate that emotion representations combined with word embedding techniques can improve the accuracy of fake news classification.

Reading Between Lines: Mapping El Orinoco Ilustrado, Guillermo Pupo Pernet

Graduate Theses and Dissertations

This dissertation examines El Orinoco Ilustrado (EOI) by Joseph Gumilla as a layered textual and cartographic artifact central to the production of colonial knowledge in the Orinoco River basin. Moving beyond surface narratives of evangelization and exploration, it interrogates the sombras and silencios implanted in the Jesuit chronicle. Through an intradisciplinary approach combining literary analysis, archival research, and visual studies, the study reveals how EOI helped construct imperial visions of space, race, and resource extraction in eighteenth-century Spanish America. The dissertation is structured around six chapters. Chapter One outlines a theoretical framework. Chapter Two provides a longue durée historical context, …

The Role Of Procedural Due Process In Equal Protection And Affirmative Action Analysis: The Narrowly Tailored Prong, Simona Grossi

UC Law Constitutional Quarterly

The Supreme Court’s decision in Students for Fair Admissions v. Harvard College marked the end of affirmative action as traditionally practiced in higher education admissions, forcing universities to seek alternative legal pathways for fostering diversity. At the same time, the Trump administration’s executive orders targeting DEI initiatives have exacerbated the legal uncertainty, raising critical questions about how institutions can preserve fairness in admissions while withstanding both judicial and political scrutiny.

This article argues that Procedural Due Process—when read in conjunction with Equal Protection—provides a constitutionally sound and structurally fair framework for admissions policies that align with strict scrutiny while preserving …

Beyond The Surface: Exploring The Experiences Of Black Female Athletes At Power 4 Institutions, Michonné Leatrice Gamble-Rivers

Electronic Theses and Dissertations

Black female athletes, have a long history of fighting for visibility and inclusion. They are celebrated and hyper-visible as performers on the court yet deemed invisible in the institutional decision making that shapes their holistic development and success. This Dissertation in Practice (DiP) challenges this structural problem looking to amplify voices that have been historically silenced by systems that reduce these individuals to mere athletic capital.

Beginning with Manuscript I, this three-manuscript dissertation is built on a conceptual framework anchored in Womanist Theory, Intersectionality, and Athletic Identity, providing the necessary critical lens to investigate challenges like double jeopardy and limiting …

Reading Teacher Perceptions: The Impact Of Educator Preparation Program Literacy Coursework And Clinical Experiences On Teacher Efficacy In Historically Underrepresented Populations, Emily Taubken

Electronic Theses and Dissertations

Despite research that indicates the critical importance and lifelong impact of early reading proficiency for students, national reading proficiency trends demonstrate most students in the United States are not yet reading at grade level, with disparities existing among historically underrepresented subgroups. Additionally, research shows that preservice and in-service teachers have documented limited feelings of self-efficacy in teaching reading specifically, suggesting limitations in preservice training for educators. To better understand how reading teachers perceive the efficacy of their preservice teacher academic and clinical experiences, especially for those who serve historically underrepresented student populations, this study seeks to document the perspectives of …

Knowledge Acquisition On Mass-Shooting Events Via Llms For Ai-Driven Justice, Benign Ihugba

All Theses

The system used entity recognition to detect vital information, which included offenders, victims, locations, and criminal instruments that support legal investigations. An experimental study conducted on actual mass-shooting datasets showed GPT-4o performs best for mass-shooting NER. The o1-mini delivered competitive performance while …

Distributed Agency And Posthuman Rhetoric In Genai-Assisted First-Year Composition Writing, Bianca E. Guzman

English Department Theses

This thesis explores the dynamic interaction between human and non-human agents in the process and production of writing. In particular, theories on the co-constitutive nature of the human-technological relationship, posthumanist theory, and rhetorical theory are used to reframe first-year writing as an act of distributive agency that always involves people, objects, and their material environments. In recognizing the essential role of “things” in first-year writing, this thesis considers how Generative Artificial Intelligence (GenAI) can be critically conceptualized and utilized as a pedagogical tool by instructors in the college writing classroom. Additionally, this thesis details an IRB-approved research study done at …

Assessing The Language And Reading Abilities Of Students With Mosaic Down Syndrome, Emma G. Conradi

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Language and reading are important skills for academic and social success, yet individuals with Down syndrome often face significant challenges developing these skills (Abbeduto et al., 2007; Martin et al., 2009). However, almost all the available research on the language and reading abilities of individuals with Down syndrome comes from research focused on individuals with Full Trisomy 21. To date, there has been virtually no research specifically examining the language and reading skills of individuals with mosaic Down syndrome (Buckley & Bird, 2002), a rare karyotype of Down syndrome. Therefore, the purpose of this study is to describe the language …

Public Perceptions Of Leadership Effectiveness In Ethiopia Over The Last Decade, Fikadu Reta Alemayehu

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Ethiopia is one of the largest countries in Africa, with a fast-growing economy, rich history, diverse agroecology, more than 70 languages, and a population exceeding 130 million. However, the country continues to face serious internal conflict, high malnutrition, and economic hardship, while the study of leadership effectiveness remains limited and lacks consistent longitudinal research. To help fill this gap, this study examined how public perceptions of leadership effectiveness and development outcomes changed in Ethiopia between 2013 and 2023, using Afrobarometer survey data. The analysis explored how citizens’ views about governance, wellbeing, and access to services evolved during a decade of …

Losing Control: Evaluative Access And The Limits Of Attributability In Angela Smith’S Theory Of Moral Responsibility, Henry Kissam

Honors Theses

The unwilling addict agent archetype–who wholeheartedly resolves to abstain from taking a drug but takes it regardless–is important to moral responsibility theorists for many reasons, but two in particular stand head-and-shoulders above the rest. The first is the frequency with which the archetype must be reckoned with through our everyday practices of moral assessment. It is not an idle thought experiment, pushing nothing but the theoretical limits of a particular theory. It is a near-ubiquitous presence in real, practical moral assessment. The second reason is a consequence of the first. Because we deal with the archetype frequently, we morally assess …

Exploring The Relationship Between Social Media And Anxiety In Deaf Community Students: A Mixed-Methods Approach., Gigi Zheng

Theses

The mental health of Deaf individuals, particularly in relation to social media engagement, is an understudied area amid growing global concerns about anxiety disorders. Deaf individuals face unique challenges, including communication barriers, social isolation, and stigma, all of which can heighten anxiety levels. Although social media offers valuable opportunities for connection and self-expression, it may also amplify stress and feelings of inadequacy when accessibility barriers persist. This mixed-methods study examined anxiety among Deaf college students and explored the cultural validity of two widely used anxiety measures—the State-Trait Anxiety Inventory (STAI) and the Beck Anxiety Inventory (BAI). Quantitative data were collected …

Mindreading And Embodiment: Beyond Mirror Neurons., Sanad Al Khatib

College of Arts & Sciences Senior Theses

This paper examines the question: how do we figure out what other people are thinking and why they act as they do, or put differently, how is it that we can read minds in daily life? For decades, the dominant view held that we explain and predict other people’s behavior by attributing to them mental states such as beliefs, desires, and intentions, represented symbolically in the brain. The embodied simulation model challenges this view, proposing that understanding others primarily relies on mirror neurons that activate both when we perform an action and when we observe someone else performing it. This …

Conceptual Gerrymandering In Sffa And Some Thoughts On How It Enables The Case’S Weaponization, David Simson

Buffalo Law Review

This Article makes two main contributions at the intersection of Constitutional Law and critical analyses of race and racial (in)equality. First, and more narrowly, the Article provides an in-depth analysis and critique of the Supreme Court’s most recent affirmative action decision in Students for Fair Admission v. Harvard (SFFA), specifically with respect to a crucial aspect of the case that has not been addressed in depth in other scholarship on the decision: how key opinions conceptualize “race” in their reasoning. The Article shows how the SFFA majority opinion and a concurring opinion by Justice Gorsuch incorporate multiple, and inconsistent, understandings …

Eligible participants were English or Spanish speakers and received TBI care between February 2023 and June 2024 at one level I trauma center emergency department (ED) and inpatient unit, two level III …

Llm-Assisted Cwe Identification, Severity Assessment, And Vulnerability Description Generation, Mohammad Jalili Torkamani

School of Computing: Dissertations, Theses, and Student Research

Identifying the underlying weakness types and assessing their severity using CWE and CVSS standards are critical steps in software vulnerability management. While timely assessment of vulnerabilities mitigates the impact of severe security incidents, automating joint CWE identification and severity assessment remains challenging due to the heterogeneity of vulnerabilities across different code granularities and programming languages. In addition, generating vulnerability descriptions is often time-consuming, as it requires extensive manual review, validation, and writing by security experts.

In this thesis, we leverage the capabilities of Large Language Models (LLMs) to automate the identification of CWE identifiers and the assessment of their severity …

Autoethnography, Poetic Performance Narratives, And Pláticas As Dialogues Of Radical Love, Miryam Espinosa-Dulanto

Bilingual and Literacy Studies Faculty Publications

This piece examines Autoethnography, Poetic Performance Narratives, and Pláticas as decolonial methodologies that challenge the coloniality of knowledge and center voices historically excluded from academic discourse. These approaches honor traditions rooted in community, solidarity, and radical love, presenting lived realities without oversimplification while inviting readers to inhabit contradictions and imagine ethical possibilities for equity. Grounded in Latin American and Chicana/Latina/Indígena feminist scholarship, this work situates these practices within a legacy of decolonial epistemologies that resist dominant Western paradigms and affirm lived experience as a site of theory-making. Through this lens, the piece seeks to: (1) bear witness to shared experiences, …

Augmenting Large Language Models To Predict Social Determinants Of Mental Health In Opioid Use Disorder Using Patient Clinical Notes, Madhavi Pagare, Deva Sai Kumar Bheesetti, Inyene E. Essien-Aleksi, Mohammad Arif Ul Alam

Health Sciences Faculty Publications

Objective

Identifying social determinants of mental health (SDOMH) in patients with opioid use disorder (OUD) is crucial for estimating risk and enabling early intervention. Extracting such data from unstructured clinical notes is challenging due to annotation complexity and requires advanced natural language processing (NLP) techniques. We propose the Human-in-the-Loop Large Language Model Interaction for Annotation (HLLIA) framework, combined with a Multilevel Hierarchical Clinical-Longformer Embedding (MHCLE) algorithm, to annotate and predict SDOMH variables. Materials and Methods

We utilized 2636 annotated discharge summaries from the Medical Information Mart for Intensive Care (MIMIC-IV) dataset. High-quality annotations were ensured via a human-in-the-loop approach, refined …

Naamkaran At The Border: Reflections On Naming, Identity, And Belonging, Vejoya Viren

Human Development and School Services Faculty Publications

Names serve as primary anchors of identity, carrying histories, cultural markers, and personal significance. Yet individuals with non-Western names frequently encounter mispronunciation, abbreviation, or simplification— practices that subtly diminish or erase aspects of identity. This article employs an autoethnographic lens to explore the complex terrain of naming across personal and professional contexts. Drawing on lived experience from India to the U.S.–Mexico border, the essay examines the emotional and social labor associated with names, the negotiation of linguistic difference, and the ethical imperative of respectful pronunciation. It situates personal narrative within scholarship on microaggressions, identity construction, and linguistic justice, demonstrating how …

Topic Modeling And Culturomic Analysis Of 30,000 Books Over 100 Years Using Gensim, Michael A. Freeman

Electronic Theses and Dissertations

This thesis explores the cultural influence of historical events on English-language fiction published between 1820 and 1929. Using a corpus of 30,256 digitized books from Project Gutenberg, Latent Dirichlet Allocation (LDA) topic modeling was applied to identify recurring themes across eleven decades. The study sought to determine whether historically significant events could be detected within fictional narratives. One clear instance emerged: Napoleon Bonaparte and the Napoleonic Wars appeared explicitly in the 1820s corpus. Beyond this, several thematic patterns were observed—such as maritime language in the 1840s, national identity in the 1880s, and youth-oriented dialogue in the early 20th century—that plausibly …
