Timelines Over Tokens: Summarization, Prompting, And Explainable Fine-Tuning For User-Level Suicide Risk Detection, Aditya Tekale

Master's Theses

This research presents a two-stage pipeline for user-level suicide risk detection from Reddit: first, inference-only prompting with summarization; second, fine-tuned encoder classification with explainability and expert validation. The data are user-level: each of the 500 C-SSRS Reddit items is one user’s chronologically concatenated posts and comments (a user timeline), annotated by psychiatrists. Stage one: six prompting strategies zero-shot, few-shot, chain-of-thought, tree-of-thought, least-to-most, and self-consistency are evaluated across six LLMs on multi-class and binary formulations; simple zero-shot achieves the highest balanced accuracy (0.53 multi-class). Error analysis shows longer inputs associate with misclassification (p = 0.002); domain-specific summarization (timelines >2,000 tokens) reduces …

The Relationship Between Strength Training And Burnout, Maddie R. Barrientos

Master's Theses

The purpose of this study was to comprehensively examine the relationship between strength training and burnout to assess whether consistent engagement in strength training would be associated with lower levels of burnout. Results of an online survey administered to 119 participants revealed that those who did strength train versus those who did not did not significantly differ in their levels of burnout, but among those who did strength training, there were significant differences in levels of burnout with how they engaged in strength training. The greater frequency of strength training participation and the greater number of muscle groups trained were …

The Mediating Role Of Moral Disengagement In The Relationship Between Facets Of Empathy And Aggression, Romiere J. Horace

Theses

Aggression is a major social and public health concern with economic, psychological, and interpersonal implications. Extensive research has examined the potential antecedents for aggressive behavior, with many different environmental, biological, and intrapsychic factors being significantly associated with aggression. Researchers have also focused on cognitive mechanisms, like empathy, as a protective factor for aggression. More specifically, research has linked lower levels of empathy to higher levels of aggression; however, the underlying mechanisms of this relationship remain underexplored. A potential explanatory mechanism is moral disengagement, which allows individuals to justify harmful behaviors and avoid self-sanctions. However, limited research has examined these constructs …

Strategies Managers Used To Mitigate Constraints For Project Success, Teela Washington

Walden Dissertations and Doctoral Studies

Persistent project failures result in significant financial losses and reduced project management efficacy. Project managers who struggle to complete projects to scope, on time, and on budget risk reducing business performance and organizational value. Grounded in change management theory and theory of constraints, the purpose of this qualitative pragmatic inquiry research project was to identify and explore effective strategies project managers employ to mitigate constraints and improve project success. Participants were 10 project managers who effectively mitigated constraints. Data were collected using semistructured interviews and publicly available documents. Thematic analysis yielded four key themes: leadership, resource management, stakeholder engagement, and …

Inoculation Interventions, Prebunking, And Media Literacy Education Are Not The Same, Author Information Removed

JMLE Submissions Open for Review

Inoculation theory-based interventions, prebunking, and media literacy education are often discussed together because all three can help people resist harmful information. Their overlap, however, does not make them interchangeable. This essay argues that clearer distinctions are needed, especially between inoculation and prebunking. Inoculation theory centers on threat-motivated resistance to influence, whereas prebunking is more accurately understood as refutational preemption. Media literacy education is a broader educational context in which either approach may be used. I focus in particular on the difference between forewarning and threat, arguing that forewarning may reasonably support inferences about threat in some contexts but should not …

How Misinformation Literacy Relates To Political Participation: An Extended Communication Mediation Model, Author Information Removed

JMLE Submissions Open for Review

This study examines how misinformation literacy is associated with political participation in digital environments through psychological and behavioral pathways. We extend the Communication Mediation Model (CMM) by integrating it with media literacy scholarship and locus of control theory. Rather than treating media literacy as a single formal theory, we conceptualize it as a scholarly framework that specifies the competencies through which individuals access, analyze, evaluate, create, and act on media messages. Within this framework, misinformation literacy refers to applied competence in recognizing, evaluating, resisting, and responding to false or misleading information. Using survey data from 499 U.S. adults, the analysis …

Beyond Technical Proficiency: A Multidimensional Analysis Of Digital Citizenship And Civic Engagement Among South Korean College Students, Author Information Removed

JMLE Submissions Open for Review

This study investigates how specific sub-dimensions of digital citizenship predict civic engagement among South Korean college students (N=497). Using hierarchical multiple regression with gender and SNS usage time as covariates, this research analyzes four subdimensions of digital citizenship—digital literacy, participation, critical perspective, and ethics—alongside three layers of civic engagement: sense of community, social responsibility, and sociopolitical participation. Hierarchical regression analyses revealed that while digital literacy functions as a baseline competency, digital participation and digital ethics serve as the most consistent predictors of civic engagement. Notably, digital participation was strongly associated with sociopolitical action, suggesting a meaningful spillover effect, while a …

Civilian Threat Reduces Distance Perceptions And Officer Punishment In Police Use-Of-Force Encounters, Stephanie A. Cárdenas, Kristyn A. Jones, Yael Granot, Emily Balcetis

Psychology: Faculty Publications

People turn to video evidence to make judgments about the justifiability of an officer’s actions in use-of-force incidents. Despite beliefs that video offers an objective account of events, use-of-force footage elicits different judgments among those watching it. Across four experiments (Ntotal = 2615), we investigated whether discrepant punishment judgments arise in part because of differences in perceptions of the physical space that separates an officer and civilian. We focus on third-party observers’ subjective perceptions, as they shape public discourse and justice outcomes, influence institutional accountability, and fuel public response. Despite watching the same video, civilians appeared physically closer to officers …

Enhancing Nursing Self-Efficacy In Advance Care Planning Conversations Through Role-Play Education: A Quality Improvement Project, Rachel Williams

DNP Projects

Background:
Advance care planning (ACP) conversations are essential for ensuring that patient healthcare preferences are understood and respected; however, nurses often report limited confidence and self-efficacy when initiating these discussions. Educational interventions that emphasize communication skills may improve nurses' preparedness to engage in ACP conversations.

Methods:
A quality improvement project utilizing a pre-post intervention design was conducted on three adult inpatient medical units within a regional Midwestern hospital. Registered nurses participated in an educational intervention consisting of ACP education, role-playing case scenarios, guided discussion, and debriefing. A modified 22-item Advance Care Planning Self-Efficacy Questionnaire was administered before and after the …

Genocide By Algorithm In Gaza: Artificial Intelligence, Countervailing Responsibility, And The Corruption Of Public Discourse, Branislav Radeljić

Genocide Studies and Prevention: An International Journal

The accelerating militarization of artificial intelligence (AI) has transformed the ethics, politics, and governance of warfare. This article interrogates how AI-driven targeting systems function as epistemic infrastructures that classify, legitimize, and execute violence, using Israel’s conduct in Gaza as a paradigmatic case. Building on interdisciplinary debates in security studies, critical technology studies, and international law, the paper advances the concept of "genocide by algorithm"—a mode of technologically mediated extermination in which opaque computational systems automate and rationalize mass violence. The study argues that these systems collapse distinctions between military and civilian targets, and between intentional and accidental harm, thereby eroding …

U.S. Public Opinion During The Rwandan Genocide And The Power Of Executive Detachment, Carly Schmitt, Matthew L. Bergbower

Genocide Studies and Prevention: An International Journal

We examine U.S. public opinion during the Rwandan genocide in the spring and early summer of 1994. Drawing on more than a dozen public opinion polls fielded during this period, we analyze Americans’ levels of knowledge about the violence in Rwanda, their views on United Nations involvement, support for U.S. military intervention, and evaluations of President Bill Clinton’s handling of the crisis. Longstanding theory recognizes public opinion as an important variable in explaining foreign policy choices during international crises. In the case of U.S. policy toward the Rwandan genocide, our analysis reveals widespread public unfamiliarity with a distant African conflict …

This study investigates the mediating effects of burnout and job satisfaction on the relationship between professional identity, occupational stress, and nurses' turnover intentions. Additionally, it explores the impact of socio-demographic factors on these relationships in the post-pandemic era.

Methods: A cross-sectional study of 338 nurses across four hospitals in Israel was conducted between June 2023 and January 2024. Self-reported questionnaires were utilized to measure turnover intentions, with professional identity and occupational stress as predictors …

Technology Platform (Peer Plus) Supporting The Work Of Peer Recovery Coaches And The Communication Needs Of Individuals In Recovery From Substance Use Disorder: Protocol For An R21 Development And Usability Trial., Amanda Coupe, Jessica Pater, Rachel Pfafman, Victor P Cornet, Elisabeth Andrews, Mindy Flanagan, Dana Albright, Abhinay Balasani, Christopher Becker, Brian Parise, Erik Hess, Tammy Toscos

Health Services and Informatics Research

BACKGROUND: Substance use disorder (SUD) represents a significant public health concern in the United States. SUD recovery is complex and individualized, and support provided by peer recovery coaches (PRCs) can improve outcomes. The PRC-client relationship requires bidirectional mediated communication that is often informal but should be trackable, efficient, and aligned with health care privacy and security regulations. Current workflows and available apps do not meet these needs, illustrating the opportunity for client-centered technology tools. We have developed Peer PLUS (People Leveraging Urgent Support; Parkview Health System, Inc), a HIPAA (Health Insurance Portability and Accountability Act)-compliant mobile app and client management …

Tracking Daily Coparenting Quality: Validation And Utility Of The Polish D‐Cop, Dorota M. Jankowska, Boguslawa Lachowska, Brandon T. Mcdaniel

Health Services and Informatics Research

Objective: To adapt and validate the Polish Daily Coparenting Scale (D- Cop PL) and to test its utility for modeling day-to-day coparenting quality.

Background: Daily coparenting quality varies across daily contexts; brief, ecologically valid tools to capture within-person change are scarce.

Methods: A 7-day diary study with 178 dual-income Polish parents of young children was conducted. Confirmatory factor analysis tested the two-factor structure (positive and negative daily coparenting dimensions), reliability, and convergent validity; measurement invariance examined factorial equivalence across mothers and fathers. Generalized Additive Models for Location, Scale, and Shape (GAMLSS) estimated same-day daily associations between coparenting quality: parental negative …

Essays On Environmental, Social, And Governance Strategy, Samuel Kim

Olin Business School Graduate Student Theses and Dissertations

The strategic consequences of an organization's Environmental, Social, and Governance (ESG) efforts are driven largely by the specific information stakeholders observe and evaluate. As firms project a growing volume of public claims and observable social outcomes, stakeholders must navigate a complex informational environment to decide how much weight to assign to what organizations say, what they do, and whether their words are consistent with their actions. Clarifying how stakeholders interpret these varied signals is therefore vital to understanding the strategic implications of ESG efforts. To that end, this dissertation asks: how are different pieces of organizational information related to stakeholder …

Constructing Heroes In The Classroom: A Rhetorical Analysis Of Abeka’S Evangelical K-12 Curriculum, Jeff S. Miller

Electronic Theses and Dissertations Archive

This study critically analyzes the rhetoric of four textbooks published by Abeka, Inc., a popular producer of curriculum for both American evangelical Christian K-12 school and homeschoolers through the lens of heroic rhetoric and anthropologist Ernest Becker’s hero systems, examining institutions’ and communities’ rhetorical construction of hero systems that provide or claim to provide relief to members’ mortality anxiety. Hero systems for each of the four textbooks are identified and examined for the ways that they function to build and maintain power hierarchies. Additionally three significant thematic threads of what constitutes heroism are identified in the textbook: biblicism, unidirectional influence, …

A Multi-Method Investigation Of Social Media Use In Adolescent Girls: Examining Emotion, Emotion Regulation, And Effects By Depression, Alison Tuck

Arts & Sciences Graduate Student Theses and Dissertations

Adolescents experience emotional instability, challenges in emotion regulation, and increased risk for the onset of psychopathology, including depression. Adolescents also engage in more social media use (SMU) than any other age group. There is significant interest inside and out of the scientific community regarding how SMU is implicated in healthy versus unhealthy adolescent emotional well-being during this developmental shift in emotional experiences, particularly among girls, who may be most vulnerable. Although research on how adolescent girls’ emotional well-being may be associated with their SMU has increased over the past decade, findings have been largely mixed and inconclusive. This may be …

Synergizing Crowd Collaboration: Enhancing Crowdsourcing Matching Via Integration Of Matching Theory And Coalition Games, Rowan Aengus Kinney

Electrical and Computer Engineering ETDs

This paper tackles the challenges inherent in crowdsourcing dynamics by introducing the CROWDMATCH mechanism. Aimed at enabling crowdworkers to strategically select suitable crowdsourcers while contributing information to crowdsourcing tasks, CROWDMATCH considers incentives, information availability and cost, and the decisions of fellow crowdworkers to model the utility functions for both the crowdworkers and the crowdsourcers. Specifically, the paper presents an initial Approximate CROWDMATCH mechanism grounded in matching theory principles, eliminating externalities from crowdworkers’ decisions and enabling each entity to maximize its utility. Subsequently, the Accurate CROWDMATCH mechanism is introduced, being initiated by the outcome of the Approximate CROWDMATCH mechanism, and employing …

Neural And Computational Mechanisms Of Effort Under The Pressure Of A Deadline, M. Andrea Pisauro, Daniele Pollicino, Lucy Fisher, Matthew A. J. Apps

School of Psychology

Deadlines fundamentally shape motivation. Research examining effort-based choices finds effort is an avoided cost. However, this overlooks how making progress on longer-term goals to be reached before deadlines motivate people to exert high effort for little immediate reward. Here, we test a framework where motivation depends on deadline pressure (work remaining / time remaining). Across four studies we use computational modelling examining decisions when physical effort makes progress on goals with deadlines. In support of the hypotheses, deadline pressure significantly impacts decision-making, shifting people from avoiding effort, to seeking the progress it makes. Using ultra-high-field fMRI, we show that functionally …

A Contextual And Sonic Analysis Of John Coltrane’S First Meditations, Matt Lind

Music ETDs

This thesis presents a contextual and sonic analysis of John Coltrane’s album First Meditations recorded in 1965. I use methods based on Dora Hanninen’s A Theory of Music Analysis to examine sonic and contextual aspects of Coltrane’s playing, including varying timbres, rhythmic tendencies, and contextual relationships in musical material. I consider pitch material from the perspective of “outside” playing, rather than traditional harmonic analysis. Considering areas of pitch, rhythm, and timbre allows the visualization of these features across each track in the album in five musical “plots.”

Regenerative Writing: The Rhetorics Of Indigenous Futurisms As Pedagogical Praxis, Madeline R. Mendoza

English Language and Literature ETDs

This dissertation explores how land-based writing and Indigenous Futurisms can reshape writing pedagogy in higher education, focusing on English courses at the University of New Mexico. At the center of this project is the Land Memoirs assignment, which I designed to encourage students to engage land as a living relative and active participant in the learning process. Through the frameworks of Indigenous Futurisms, Land as Pedagogy, Rhetorical Sovereignty, and Pueblo understandings of marking, I analyze the rhetorical choices across student multimodal narratives, reflections, and interviews to examine the assignment’s pedagogical impact. My findings reveal epistemic differences in how Indigenous …

Surveyception: An Exploration Of Deceptive Survey Forms, Muhammad Danish

Computer Science ETDs

Survey platforms such as Google Forms and Microsoft Forms are widely used for feedback, data collection, and engagement, but scammers increasingly exploit them to distribute phishing and deceptive attacks. This thesis presents a large-scale study of survey-form abuse across ten major providers. We collected 140,000 forms from three sources: public posts on X, search-engine results, and web pages from the top 10 million DomCop-ranked domains. Using automated filtering and manual qualitative review, we identified 2,645 forms requesting sensitive information and classified 566 as scams. These forms used techniques including phishing, private-secret theft, account and personal-data harvesting, financial deception, and psychological …

Examining Conditional Indirect Media Effects Through Normative Perceptions: The Role Of Traditional Family Gender Role Expectations And Stigmatizing Beliefs In Human Papillomavirus Vaccination, Moonsun Choi

Communication ETDs

This dissertation examines how indirect media effects operate through normative perceptions within a gendered and stigmatized health context of HPV vaccination. Specifically, this study investigates how these normative mediation processes are conditioned by traditional family gender role expectations at the norm formation stage and stigmatizing beliefs about HPV vaccination at the normative influence stage. A cross-sectional survey was conducted with mothers of children aged 9 – 12 in the United States in June 2025. The key findings show that while gendered perceptions of HPV vaccination persist, the underlying normative mechanism operated in similar ways across gender-referent contexts. Injunctive norms were …

Making Meaning Of Gendered Experiences: A Mixed Methods Analysis Among U.S. College Students, Andrea Bancroft

Individual, Family, and Community Education ETDs

Gender inequities rooted in patriarchal norms shape the experiences of college-going emerging adults across many domains, often to the detriment of young women. In this study, we applied a mixed-methods approach to analyzing how college students interpret and make meaning from gendered experiences, and how the meaning making process relates to these emerging adults’ sense of university belonging. Participants provided written narratives of a gendered experience and completed a survey about university belonging. Through our qualitative analyses of the narrative responses, we identified four themes that represent cultural socialization messages that these participants engaged with in their narratives: bioessentialism, expectations …

Prenatal Alcohol Exposure Induces Vulnerability To Mild Stress Through Heightened Limbic Glial Activation And Cytokine Release, Justine R. Zimmerly

Biomedical Sciences ETDs

Fetal alcohol spectrum disorder (FASD) results from prenatal alcohol exposure (PAE) and is linked to development of mood disorders, which in turn are driven by dysregulation of the sympathetic nervous system, the neuroendocrine hypothalamic-pituitary-adrenal (HPA) axis, and the central nervous system (CNS) neuroimmune response to stressors. PAE alters brain glial activation and proinflammatory cytokine expression through secondary challenges such as psychological stressors. The goals of the experiments presented in this dissertation were to 1) examine peripheral glucocorticoid receptor function following mild acute stress in adult PAE offspring, 2) characterize a sensitized cytokine stress response in the hippocampus, medial prefrontal cortex, …

Interpretable Case-Control Inference Through Log-Linear General Location Models, Zacharia Stuart

Mathematics & Statistics ETDs

This dissertation analyzes one of the few publicly available NFL injury datasets to study field type and non-contact lower-limb injuries. Field type is studied jointly with other risk factors to understand how these factors interact to affect injury risk. The data were gathered through a case-control sampling scheme, which limits direct inference on absolute injury probabilities. While not the most common approach for case-control data, this dissertation models the retrospective distribution directly through Log-Linear General Location Models (Log-Linear GLOMs). Through a log-linear structure placed on a log-odds-ratio reparameterization, the model provides directly interpretable marginal and interaction contributions to injury log-odds …
