News Mediated Reporting And Governmental Narratives About The Enforcement Of Elite Criminality: Exploring The Social Construction Of Financial Frauds And Discrepancies In Punishment, Dominic J. Zicari

Theses and Dissertations

This study examines how financial crime enforcement decisions are socially constructed through a qualitative content analysis of news articles and government communications pertaining to two specific cases: the Enron scandal of 2001 and the subprime mortgage crisis of 2008. The study was guided by a theoretical framework that utilizes Barak’s (2017) theory of state-routinized crime control. The rigorous analysis of 394 news articles and government communication documents revealed that the media and the state rarely framed the subprime mortgage crisis as a criminal issue. Although the Enron scandal was frequently described as financial crime, journalists and government communicators were often …

Radical Hope Amid Generational Oppression And Puerto Rican Well-Being, Natalia Gomez Giuliani

Theses and Dissertations

Oppressive systems (e.g., colonialism, racism, capitalism) create a disparate distribution of power that, through various mechanisms, negatively impacts the health and well-being of members of the oppressed group. Boricuas have experienced over 500 years of oppression, with the island currently maintaining a colonial relationship with the United States. As these adverse effects of oppression are identified, the need for protective factors (e.g., hope) has emerged. This study explored how islander Boricuas practice radical hope, understand their history of oppression and resistance, and how they perceived it to impact their overall well-being. Utilizing a phenomenological qualitative approach, I conducted 15 semi-structured …

Verbs Are Tricky: Does Orthography Support Verb Identification In Typically Developing Children Ages 3–8?, Grace T. Clark, Gabriella Pesantes, Madison Skibicki

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Purpose:
This study examined whether orthographic representations—seeing a printed word while hearing it—facilitate verb identification accuracy in typically developing children and whether developmental or literacy factors modulate this effect.

Method:
One hundred eight English-speaking children ages 3–8 years (M = 5.86) completed a web-based verb learning task through Children Helping Science. Participants were randomly assigned to an orthography-present or orthography-absent condition while learning six novel verbs paired with dynamic action videos. Accuracy during a two-alternative forced-choice test was coded from parent-verified pointing responses. Caregivers completed a literacy interest questionnaire, and children completed a letter–sound correspondence task. Multilevel logistic regression …

Leveraging Large Language Models To Create Learner Personas For Training Design, N. Lovett, M. Yang, K. Herman, B. Li, M. Sosonkina, W. Purwanto, P. Jiang, M. H. Wu

Electrical & Computer Engineering Faculty Publications

This case examines the innovative use of Large Language Models (LLMs) to generate learner personas for developing learner-centered cybersecurity training materials when direct access to initial learner data is not available. The team developed a nine-stage iterative process for creating and refining AI-generated personas to address this constraint, integrating ethical review, stakeholder feedback, and action research principles. The process expanded upon Kouprie and Visser’s (2009) empathic design framework to ensure cultural responsiveness and mitigate potential biases in LLM outputs. Through multiple refinement cycles, initial generic personas evolved into detailed, context-rich archetypes which informed the development of effective and context-responsive training …

The Forms Of Representation: How To Be A Kantian Realist, Willem A. Devries

Faculty Publications

Sellars argued that Kant did not make certain distinctions concerning space and time, and because of this adopted his transcendental idealism. Once these distinctions are made, the path to realism remains open. Sellars' argument is not entirely clear. This essay attempts to clarify the argument, showing why Sellars believed he could remain a scientific realist while also adopting a Kantian style epistemology.

Retention Rate Of The Human Performance Course In Flight Training, Ahmet Uğur Avcı, Erdinç Ercan

“Lost-In-The-Later”: Framework For Quantifying Contextual Grounding In Large Language Models, Yufei Tao, Adam Hiatt, Rahul Seetharaman, Ameeta Agrawal

Computer Science Faculty Publications and Presentations

Large language models (LLMs) are capable of leveraging both contextual and parametric knowledge but how they prioritize and integrate these sources remains underexplored. We introduce CoPE, a novel framework for systematically quantifying contextual grounding in LLMs. CoPE distinguishes between contextual knowledge (CK) and parametric knowledge (PK), enabling fine-grained attribution across languages and tasks. Using our newly created MultiWikiAtomic dataset in English, Spanish, and Danish, we analyze how LLMs integrate context, prioritize information, and incorporate PK in open-ended question answering. We find that across models and languages, only around 50 to 76 percent of outputs are grounded in the given context, …

Computer Science Faculty Publications and Presentations

Topic discovery in scientific literature provides valuable insights for researchers to identify emerging trends and explore new avenues for investigation, facilitating easier scientific information retrieval. Many machine learning methods, particularly deep embedding techniques, have been applied to discover research topics. However, most existing topic discovery methods rely on word embedding to capture the semantics and lack a comprehensive understanding of scientific publications, struggling with complex, high-dimensional text relationships. Inspired by the exceptional comprehension of textual information by large language models (LLMs), we propose an advanced topic discovery method enhanced by LLMs to improve scientific topic identification, namely SciTopic. Specifically, we …

Minds, Made Up Or Malleable? Covert Commands At The Eclipse Of Vaccine Communications, David H. Lee

Publications and Research

Abstract: Although millions have died from SARS-CoV-2 illness, COVID vaccines are credited with stemming the tide. Vaccinations and boosters significantly decrease the incidence of severe illness and death (even if they don’t usually prevent COVID-19 infection). Despite the success of global vaccination efforts, frequent reports of vaccine hesitance and refusal suggest that public health communications need improvement.

The chapter begins by acknowledging adverse events associated with COVID vaccination, including rare cases of anaphylaxis, GBS, and myocarditis. An inoculation-theoretic rationale is offered for this admission of vaccine risks: just as immune defenses mount when organisms are exposed to pathogens, so too …
