Beyond Detection: A Batch-Based Ai Framework For Temporal And Event-Correlated Trend Analysis Of Misinformation On Social Media, Vishnu Tejas Vijayaraghavan

Theses

The rapid spread of misleading information on social media influences public behaviour and complicates crisis communication. Although transformer models such as BERT accurately detect misinformation at the post level, most studies analyse posts in isolation and overlook howmisinformation fluctuates over time or responds to major events. This study addresses that gap by developing an end-to-end analytical workflow that integrates BERT-based classification with temporal aggregation, topic clustering, anomaly detection, and event alignment. The analysis uses 10,700 COVID-19–related tweets (6,420 training, 2,140 validation, and 2,140 testing). Because timestamps were unavailable, synthetic timestamps were assigned using an evenly spaced date range between 1 …

This qualitative study explored the relationship between secondary students’ perceptions of teacher involvement and their academic success in asynchronous online social studies courses. Participants included 22 students from two accredited high schools in Mississippi, one fully online and one traditional brick-and-mortar school, both of which offered asynchronous social studies courses approved by the state …

Knowing One's Place At The Table: Taste As A Means Of Othering In The American Colonies, 1700-1775, Nicholas Harp

Master's Theses or Doctor of Nursing Practice

This thesis began as an inquiry into a simple question. How did people in the American colonies talk about the food that they ate? This question led to a fascinating look into the social dynamics of the people living in eighteenth century America. Their own personal writings demonstrate how they understood their place in society through the food that they ate. Moreover, they often wrote about the way that other people ate in ways that alienated or discriminated against different ethnic groups. A look into the secondary historiography revealed that other historians had noticed this trend. However, very few addressed …

The Relationship Between Exercise And Prospective Memory: A Meta-Analysis, Shaykhah Salman Alqahtani

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 …

Interpreting, Implementing, And Imagining Transfer Policy In South Carolina: A Transformative Institutional Ethnography, Lori Allen Heafner

Electronic Theses and Dissertations

This institutional ethnography explores the implementation of vertical transfer policies in South Carolina, where community and technical college students face persistent barriers in transferring credits to four-year institutions. Despite the growing population of students who begin their academic careers at two-year colleges with aspirations for a bachelor’s degree, South Carolina lacked a formal, statewide transfer policy until 2023. This dissertation investigates how front-line professionals, such as transfer coordinators, transfer advisors, registrars, and other transfer personnel, interpret and implement new transfer policies in practice. The study centers their experiences to illuminate the disjuncture between policy design and institutional realities.

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 …

Forage Preference In Two Geographically Co-Occurring Fungus Gardening Ants: A Dietary Dna Approach, Matthew Richards-Perhatch V, Elizabeth Boshers, Matthew Greenwold, Jon N. Seal

Biology Faculty Publications and Presentations

Traditional methods of forage identification are impractical with non-leafcutting fungus gardening ants, making diet-related ecological and life history questions difficult to study. To address this limitation, we utilized dietary DNA metabarcoding on excavated ant fungus gardens to generate forage diversity metrics for the two co-occurring species Trachymyrmex septentrionalis and Mycetomoellerius turrifex. Ten fungus garden samples from each species were collected from a 60x70 m plot in East Texas. Each of the colonies we sampled was paired with a colony from the other species within 3 m of it. Plant forage diversity was assessed with chloroplast trnL primers, and insect frass …

An Analysis Of Portuguese Colonial Representations Of Sinhalese Women, Chandra R. De Silva, Ramani Hettiarchchi

History Faculty Publications

The history of Sri Lanka until recently has been written mostly as the history of men in the country. This has been particularly true of the early modern period, for which existing records are mostly those of visiting colonizers who were mostly men, writing about their dealings with those in power or with those from whom they could gain profit. This article is an attempt to collect and analyze the admittedly limited data on how the Portuguese who gained political authority over parts of the coastal areas saw local women. It is limited to the women of the majority community …

Ethnic Identity, Parental Involvement, And Academic Outcomes: A Qualitative Study Of African International Students' Experiences, Kenanile Olivia Marie-France Bigba

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

This qualitative study explored how parental involvement intersected with cultural backgrounds and values through ethnic identity formation among African international students, and how these interactions influenced students' self-concept clarity, self-esteem, and subsequent academic attitudes and performance.

How Presidents Shift Ideological Stances In Legislative Elections: Evidence From South Korean Presidential Speeches, Doyeon Park

Department of Political Science: Dissertations, Theses, and Student Research

Presidents have a strong desire to lead their parties to victory in elections. However, relatively little attention has been paid to their ideological stances in legislative elections. This contrasts with extensive research on the ideological strategies of parties and candidates who directly compete for office. How do presidents adjust their ideological positions in legislative elections? This study examines the institutional dynamics surrounding presidents, focusing on their dual responsibilities and the role of legislative elections as a referendum on the presidency. It also considers presidential popularity as a factor that influences these dynamics. I argue that presidents are more likely to …

The Partsongs Of Samuel Coleridge-Taylor, Alan Davis

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

This document examines the complete set of thirteen partsongs by Samuel Coleridge-Taylor (1875-1912) a body of choral works underrepresented in both scholarship and performance. Before the twentieth century, English partsongs had already developed a rich lineage through composers such as Charles Hubert Hastings Parry, Charles Villiers Stanford, Edward Elgar, and Charles Wood. Around 1900, the genre flourished further in the works of Gustav Holst, Ralph Vaughan Williams, Gerald Finzi, and Herbert Howells, whose partsongs were published by Novello & Co. and featured in The Musical Times. Within this broader context, Coleridge-Taylor’s contributions stand apart: his partsongs reveal a distinctive harmonic …

Soil Characterization With Proximal Geophysics, Sophia M. Becker

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

High quality soil data is crucial for addressing numerous threats to human well-being such as water scarcity, food insecurity, and intensified natural disasters. True soil property values are determined by analyzing soil samples in a laboratory, but soil sampling is often expensive and time-consuming. Some in-field point sensors and remote sensing products are available to measure soil properties, but they have inherent limitations in measurement extent and resolution. Geophysical methods can fill the measurement scale gap between point measurements and remote sensing products, but various research questions remain open. This dissertation aims to advance understanding of geophysics-derived soil property measurements …

The Long Arc Of Love: A Humanizing Meditation On Enduring Former Student–Teacher Relationships, Cara Morgenson

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

As the title suggests, this is a humanizing meditation on enduring relationships beyond the classroom construct of student-teacher, with a theoretical framing that braids strands of critical theories and pedagogies to consider critical love, authentic caring, and humanization as a liberatory and justice-oriented framework (see del Carmen Salazar, 2013; Freire, 1970/2020; hooks, 1994; Sealey-Ruiz, 2020, 2021; Valenzuela, 1999). In the spirit of multiple and eclectic methods (Nader, 1972), the methodological framing braids (1) critical autoethnography as feminist method (Adams et. al, 2015; Boylorn & Orbe, 2014; Ettorre, 2017), (2) portraiture (Lawrence-Lightfoot & Hoffman Davis, 1997), and (3) narrative epistemology in …

Efficient Algorithms For Mitigating Uncertainty And Risk In Reinforcement Learning, Xihong Su

Doctoral Dissertations

Reinforcement learning~(RL) studies the methodologies of improving the performance of sequential decision-making for autonomous agents and has achieved remarkable success in domains such as games, robotics, autonomous systems, finance, and healthcare. The Markov Decision Process~(MDP) is a mathematical framework for modeling agent-environment interactions in sequential decision-making problems. There are two primary sources of uncertainty in RL: epistemic uncertainty and aleatoric uncertainty. In RL, risk refers to the potential for an agent's policy to lead to undesirable outcomes, especially when the environment is uncertain. In many domains, researchers seek policies that maximize the objectives while mitigating the uncertainty and risk in …

Imatinib mesylate (IM) and other BCR-ABL tyrosine kinase inhibitors (BCR-ABLi) are the mainstay of chronic myelogenous leukemia (CML) treatment. However, activation of circumventing signaling pathways and quiescence may limit BCR-ABLi efficacy. CDK8/19 Mediator kinases have been implicated in the emergence of non-genetic drug resistance. Dissecting the effects of pharmacological CDK8/19 inhibition on CML survival in response to BCR-ABLi, we found that a selective, non-toxic CDK8/19 inhibitor (CDK8/19i) Senexin B (SenB) and other CDK8/19i sensitized K562 cells to different BCR-ABLi via attenuation of cell cycle arrest. In particular, SenB prevented IM-induced upregulation of genes that negatively regulate cell cycle progression. SenB …
