Data Augmentation And Imputation For Sparse Learner Performance Data In Intelligent Tutoring Systems, Liang Zhang

Electronic Theses and Dissertations Archive

Intelligent Tutoring Systems (ITSs) leverage computer-aided technologies to provide dynamically adaptive instruction tailored to individual learners. Recent advancements in Artificial Intelligence (AI) have further enhanced their capacity to deliver responsive, personalized learning experiences. As learners interact with ITSs by responding to questions, their performance data, such as correct and incorrect answers, become essential for assessing and predicting latent knowledge states through analysis and modeling. However, real-world learner data frequently suffer from sparsity due to incomplete interactions, unanswered questions, and missed attempts. Such missing information poses significant challenges, undermining the accuracy of learner modeling and the effectiveness of personalized instruction. To …

The Impact Of High-Fidelity Urinary Catheterization Simulation On Occupational Therapy Students In A Graduate Curriculum: A Pilot Study, Haley Blaney, Reagan Schonhard, Maddie Spring, Rachael Eads, Claire Donahue

Masters Projects

The most recent estimate of the annual incidence of spinal cord injury (SCI) in the United States is approximately 54 cases per one million people. Occupational therapy (OT) students may not feel adequately prepared to treat and educate clients with SCIs about bladder management if they are not exposed to real-life scenarios during their graduate curriculum. Using high-fidelity simulations (HFS) offers a high level of interactivity and realism for the learner, often using human patient simulators and taking place in realistic, mock clinical settings. This study aims to examine the effects of a HFS on OT student's confidence with urinary …

Drug Recognition Experts’ Perspectives On The State Of Maryland’S Legalization Of Cannabis And Its Impact On Impaired Driving, Raymond D. Brooks

Walden Dissertations and Doctoral Studies

Motor vehicles have become both affordable and practical to own. As a result, law enforcement has been tasked with enforcing laws related to safe vehicular operation on the roadways nationwide. Further, much like alcohol, drug influence causes concern for motorists, and with the introduction of cannabis legalization, there is a clash between use, public interaction and vehicle operation. Cannabis consumption in public, the perception that use is allowed anywhere, and the impact that impairment has while driving can be a concern for those tasked with enforcing laws that some perceive to be allowed. This study introduces cannabis legalization within the …

Implementation through the AI Writing Guide website provides practical tools including prompt templates, annotated examples, and instructional materials that demonstrate …

Under Pressure: Performance Loads And Recovery In Ncaa Division I Women’S Soccer During Fixture Congestion, Jade X. Dawson, Fabiano T. Amorim

Health, Exercise, and Sports Sciences ETDs

Soccer places high physiological demands on athletes, and match congestion—playing more than two games per week—is a growing concern at the NCAA Division I level. Limited recovery time between matches can impair performance and increase injury risk, prompting widespread use of recovery strategies. However, research on their effectiveness remains inconclusive, and most existing studies focus on male athletes, leaving a gap in evidence specific to female players. This review and observational study aim to evaluate non-nutritional recovery strategies in NCAA Division I women’s soccer and examine how recovery duration influences performance.

Match load data were collected from eleven female athletes …

Mitigation Behaviors Of Homeowners And Renters In The Wildland Urban Interface, Aishwarya Borate, Omar Pérez Figueroa, Douglas Houston, Christopher Ihinegbu, Ariane Jong-Levinger, Jochen E. Schubert, Brett F. Sanders

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Residential development within the wildland-urban interface (WUI) has greatly expanded in the United States since the 1990s, amplifying wildfire risk by placing people and structures in greater proximity to flammable vegetation. Household wildfire mitigation actions can vary substantially by cost, knowledge required, and perceived effectiveness, but few studies have examined them separately and how their adoption varies by housing tenure in the context of wildfires. To address this gap, we surveyed residents living in WUI areas within Southern California near recent burn scars in the Santa Ana and San Bernardino Mountain ranges. Drawing on the Protection Motivation Theory and the …

Psilocybin Treatment Extends Cellular Lifespan And Improves Survival Of Aged Mice, Kosuke Kato, Jennifer M Kleinhenz, Yoon-Joo Shin, Cristian Coarfa, Ali J Zarrabi, Louise Hecker

Faculty, Staff and Students Publications

Psilocybin, the naturally occurring psychedelic compound produced by hallucinogenic mushrooms, has received attention due to considerable clinical evidence for its therapeutic potential to treat various psychiatric and neurodegenerative indications. However, the underlying molecular mechanisms remain enigmatic, and few studies have explored its systemic impacts. We provide the first experimental evidence that psilocin (the active metabolite of psilocybin) treatment extends cellular lifespan and psilocybin treatment promotes increased longevity in aged mice, suggesting that psilocybin may be a potent geroprotective agent.

Mediating The Exquisite: Aesthetic Affordances Of The Network Arts, Seth Adams

Journal of Network Music and Arts

This paper argues that the Network Arts afford uniquely nuanced aesthetic interactions among humans and between humans and machines. After defining these moments under a new concept I call exquisite musicking, I investigate how distributed networks of human and nonhuman actors create experiences that challenge or complicate traditional notions of agency, ensemble, aesthetics, and synchrony. Using Actor-Network Theory as a lens of inquiry, I explore the exquisite affordances of network-based musicking, discussing how pitch, timbre, and texture are co-created in networked performances. I also examine how exquisite musicking could serve as a fruitful concept in music education, particularly in pedagogical …

Tumult, Terror, And Tripping: The Roles Of Psychedelics And Radical Politics In The Counterculture, Daniel J. Melbert

The Purdue Historian

From the immense political upheaval of the Civil Rights Movement and anti-war protests to the advent of the hippie counterculture and its psychedelic aesthetic, the 1960s is commonly conceptualized as a significantly transformative period in American history, socially, culturally, and politically. While this is certainly an accurate observation, the political and cultural shifts that occurred within this period are typically approached as separate, if not disparate, segments within the development of the period. The counterculture is often approached solely within the confines of its art, aesthetics, bohemian lifestyle, and perhaps most ubiquitously, the use of psychedelic drugs. As a result, …

Xyy: Why? Science For The People And The Xyy Controversy, Fern Rice

The Purdue Historian

The mid-20th century saw a boom of scientific discoveries in genetics as people sought to understand the American political landscape through genomes. The desire to understand criminality through genetics rose as counterculture surged. The genetic defect known as “XYY syndrome” became connected to criminality through biased medical studies and sensationalized criminal cases worldwide. When the National Institute of Mental Health began to fund studies attempting to prove a link between XYY syndrome and criminality, organizations concerned with scientific justice took notice. The leftist organization Science for the People campaigned against an XYY study in Boston, deeming it unethical and biologically …

Co-Design Of A Program For Medical Students’ Experiential Learning In Community-Engaged Research, Daenique H. A. Jengelley, Tess D. Weathers, Dustin O. Lynch, Morgan E. Ness, Luis Garcia, Gina E. Claxton, J. Dennis Fortenberry, Tamara S. Hannon

Journal of Community Engagement and Higher Education

Medical education may lack experiential training on authentic community engagement (CE). Employing a human-centered design approach with medical faculty and students to identify goals, opportunities, needs, and barriers to implementing CE research, we developed an Experiential Community Engagement Learning Series (EXCELS) pilot program. EXCELS supported both our community partners and medical students as a platform from which to learn from each other. EXCELS can be accomplished virtually, incorporated in medical training, and disseminated broadly.

Journal of Community Engagement and Higher Education

Many social innovation efforts are aimed at meeting social challenges presented by the aging of the population, yet older adults are often excluded from such efforts. The purpose of this case study was to examine an approach used in a midsized university in southeast North Carolina to create intergenerational opportunities for students, local community organizations, and older adult residents of the surrounding area to collaboratively develop suggestions for addressing challenges facing the older adult population.

First-Year Intersections: Professional Preparation And Civic Engagement Across Four New American Colleges And Universities (Nacu) Campuses, Shereen Ilahi, Chastity Blankenship, Andy Morris, Jeffrey Thomas

Journal of Community Engagement and Higher Education

Four institutions hypothesized that civic engagement in first-year courses reinforces career readiness by helping students think critically, communicate effectively, and work well with diversity. We measured teamwork skills, the ability to synthesize and apply different perspectives, and the ability to express, listen to, and adapt ideas based on the perspective of others. We compared self-assessments to direct assessment of student-created artifacts and found a positive correlation that encourages further enquiry.

Feasibility Of A Peer-Facilitated Video-Based Mental Health And Substance Use Service-Learning Program, Mara Carmina A. Tamayo, King Filart, Maria Regina Hechanova

Journal of Community Engagement and Higher Education

This study examined the feasibility of implementing a peer-facilitated mental health and substance use video-based program delivered by psychology students as part of service learning. The program was delivered on-site and online. Findings reveal improvements in knowledge, attitudes, refusal self-efficacy, and adaptive coping among on-site participants. However, there was no effect on online participants given many implementation challenges. Recommendations include delivering the program on-site, strengthening training for facilitators, increasing program duration, and shortening the videos.

Community-Based Art Education In Early Field Experiences: Facilitating Opportunities For Preservice Art Education Students To Support Students With Disabilities, Kristin Vanderlip Taylor

Journal of Community Engagement and Higher Education

Preservice art education students are often required to engage in Early Field Experience (EFE) observation hours before entering a credential program. Community-based art education (CBAE) projects may provide them with EFE opportunities to apply what they are learning in art education environments beyond the traditional classroom. This article describes one such CBAE project with a nonprofit organization providing arts instruction to students with different abilities and needs, primarily those with autism spectrum disorder (ASD).

Teaching About Substance Use Recovery: The Pedagogical Power Of Community-Based Learning, Jumi Hayaki, Isabelle Jenkins

Journal of Community Engagement and Higher Education

Community-based learning (CBL) is a form of experiential learning that integrates academic theory and content with active service in an applied setting. CBL is especially well suited for teaching about complex social issues. We present the case study of a psychology course on substance use recovery that leverages CBL to dismantle stereotypes, humanize a highly stigmatized mental health problem facing society, and afford students the opportunity to consider their own privilege and positionality.

The Association Between Callous-Unemotional (Cu) Traits And Suicidal Behavior In A Psychiatric Inpatient Adolescent Sample, Emily C. Kemp Phd, Paige Picou Phd, Erin P. Vaughan Ma, Emily L. Robertson Phd, Toni M. Walker Phd, Paul J. Frick Phd, Ryan M. Hill Phd, John De Back Md

Journal of Applied Research on Children: Informing Policy for Children at Risk

Introduction: Suicide in adolescents poses a major public health crisis as the second leading cause of death in youth. Suicidal thoughts and behaviors (STBs) are a principal reason for psychiatric hospitalization among adolescents. Numerous studies across development have identified risk factors (e.g., depression, borderline personality (BPD) features, family history of suicide) associated with STBs, while research in adults largely reports that the affective component of psychopathy, captured by callous-unemotional (CU) traits, is negatively associated with STBs. However, the relationship between CU traits and STB risk among adolescents remains unclear.

Methods: The present study tested associations between self-reported CU …

The State Of The Field On Popular Culture Themed (Pct) Courses: Introducing The Journal Of Thematic Instruction, Kathy R. Doody Ph.D., Pamela Schuetze Ph.D., Jill M. Swirsky Ph.D.

Journal of Thematic Instruction

As universities adapt to meet evolving student needs, popular culture themed (PCT) courses have emerged as an innovative approach that integrates media with academic theory to foster engagement, critical thinking, and interdisciplinary connections. PCTs use popular culture themes that are not directly related to the course content to teach the course content. Despite their growing use across diverse disciplines, from STEM to the humanities, there is a lack of cohesive understanding, consistent terminology, and empirical research on the impacts of PCT courses in higher education.

This paper reviews existing literature on PCT courses organized by discipline, highlighting representative pedagogical strategies, …

Unraveling The Scarf: How Dimensions Of The Scarf Model Influence The Relationship Between Workplace Exclusion And Turnover Intentions, Matthew Aplin-Houtz

Ed G. Smith College of Business Graduate Works

Workplace exclusion – often subtle and difficult to detect – significantly contributes to employee disengagement and turnover, costing US organizations over $1 trillion annually. This study examines how exclusionary behaviors (EBs) influence turnover intentions (TOIs) through disruption of psychological needs, using Rock’s SCARF model (Status, Certainty, Autonomy, Relatedness, Fairness) and self-determination theory. A two-wave survey of full-time US employees (N = 277) assessed EB, SCARF-based need satisfaction, and TOI. Partial least squares structural equation modeling revealed that EB significantly undermines all five SCARF domains, but only fairness and status mediated the EB–TOI link. Certainty, autonomy, and relatedness did not have …
