Context Matters: Evaluating Llm-Generated Knowledge Graph Schemas, Ritvik Garimella, Riju Marwah, Atishay Jain, Khusham Bansal, Amit Sheth

Publications

Knowledge graph (KG) schema engineering is labor-intensive and resists automation at scale. We investigate whether LLMs can generate domain-specific KG schemas of sufficient quality for downstream symbolic reasoning. We propose a tiered contextual framework that varies domain context richness across four levels: zero context, domain scope, task requirements, and data distribution. Generated schemas are evaluated intrinsically on BioRED (600 PubMed abstracts, multi-type entities and relations), where automated tiered schemas match an established KG construction baseline at 79.9% EC, with edge conformance rising from 47.5% at L1 to a stable 78–80% from L2 onward. Extrinsic evaluation on a 50-record MedHop controlled …

Equal Goals, Unequal Standards: The Policy Debate On Goalpost Dimensions In Women’S Football, Tarlan Chahardovali, Johan Rewilak Ph.D.

Faculty Publications

This study critically examines proposals to reduce goalpost sizes in women’s football; a debate often framed as a practical adjustment to accommodate physiological differences between male and female goalkeepers. Using data from men’s and women’s professional English football within two distinct periods (1951–1975 and 2011–2025), we investigate whether differences in goalkeepers’ height, gender and training are associated with variations in goals conceded. Our findings reveal that taller goalkeepers concede fewer goals; however, this relationship is U-shaped and this benefit diminishes beyond a certain point. We also find that improved coaching and investment, proxied by additional training via national team selection, …

Doing Less With More: A First-Principles Exploration Of The Suitability Of Agentic Computing Over Alternative Architectural Choices, Ritvik Garimella, Biplav Srivastava, Amit Sheth

Publications

There is growing interest in automating business activities with Agentic Artificial Intelligence (AI) due to latter's seeming ease of use. Never has it been easier, or costlier, to do less with more. However, little is known about when agents are preferable to established alternatives such as local computation, Representational State Transfer (REST), the Simple Object Access Protocol (SOAP), and the Model Context Protocol (MCP), particularly when development speed, performance, and operational cost are considered. We investigate this question using a controlled mathematical task that compares seven methods on a benchmark of 1,000 arithmetic expressions where semantics of operator precedence has …

Association Between Athletic Trainers And Frequency Of Pediatric Orthopedic Visits, Abaigeal Field, James M. Mensch, Courtney Meyer, Susan W. Yeargin

Clinical Practice in Athletic Training

Context: There is sparse research on the relationship between athletic trainer (AT) employment and the number of athletes presenting to orthopedic clinics with sports-related injuries. The purpose of this study is to determine if athletic training services are associated with the frequency of first-time orthopedic office visits for sports-related injuries.

Methods: A retrospective chart review collected injuries between January 1, 2018 and December 31, 2020 from the electronic health records system for a hospital network in the Southeast United States with 6 orthopedic clinics and included 48 high schools hosting 20 sports with at least 1 AT per school.

One Size Does Not Fit All: Revisiting World Models And Neurosymbolic Ai, Amit P. Sheth, Madhur Thareja, Anushka Pawar, Niyati Rawal

Publications

World models are being built twice, from opposite ends, without a shared theory of how the two halves should meet. One lineage grounds the world model in perception: a self-supervised, latent-predictive encoder – exemplified by Joint Embedding Predictive Architectures (JEPA) – that learns the structure of sensory experi-ence. A second, older lineage grounds the world model in cognition: an explicit, inspectable structure of entities, rules, and constraints, ranging from knowledge graphs to formal logic to physical law. Neither lineage alone has produced a world model that is simultane-ously adaptive and auditable. We argue this is not solved by picking a …

“It’S Its Own Toxic”: Occupational Opportunities And Barriers For Lgbq+ Collegiate Athletic Administrators, Colleen S. O'Connell, Michelle E. Moosbrugger, Jill Kochanek, Elizabeth M. Mullin

Journal of Issues in Intercollegiate Athletics

Athletic administrators hold positions of influence within intercollegiate sport, yet their experiences, especially in relation to sexual identity, remain underexamined. The purpose of this study was to explore the occupational experiences and environments of LGBQ+ intercollegiate athletic administrators using a narrative inquiry qualitative design. Sixteen administrators, who occupied various positions across all NCAA levels, were interviewed. Guided by Sexual Stigma and Prejudice Theory and Poststructuralism Theory, collected data were analyzed at the semantic and latent levels using reflexive thematic analysis. Two distinct themes were generated: LGBQ+ administrators described both positive and negative aspects of their workplaces. Inclusive environments were committed …

Relationships Between Shared Group Properties: Theory, Measurement, Estimation, And Adjustment, Mark A. Maltarich, Paul D. Biese, Nichelle C. Carpenter

Faculty Publications

Teams researchers, meta-analysts, and others often study relationships between group-level constructs measured by aggregating individual-level variables, but it is well-known that group-mean correlations are influenced by individual-level relationships. We review multilevel issues and current practices in estimating and adjusting group-mean associations. We give special attention to comparisons across levels of analysis, and to adjustments for estimating population parameters. A Monte Carlo simulation study indicates that the two most commonly used adjustments in meta-analysis are ineffective in estimating population-based effect sizes. They frequently overestimate true relationships, sometimes severely. Indeed, simulations show that common adjustments move estimates away from population values in …

Patients Willingness To Seek Help From Pharmacists In The Management Of Rheumatoid Arthritis: A Qualitative Study, Omkar Ghodke, Erin Holmes, Meagen Rosenthal, Yinan Huang, Marie Barnard

Podiums

Background: This study explored the willingness of rheumatoid arthritis (RA) patients to seek help from pharmacists for their disease management. While pharmacist interventions are known to enhance medication adherence and health outcomes, patient engagement with pharmacists remains low. Understanding the factors that influence RA patients' willingness to use pharmacy services is essential for improving patient outcomes and optimizing the role of pharmacists in RA management. Using the Integrative Model of Behavioral Prediction (IMBP), this study identified the factors influencing willingness to use pharmacists and pharmacy services among patients with RA. Methods: This study utilized semi-structured interviews targeting individuals 26 years …

Multilevel Drivers Of Missed Opportunities For Hiv Prevention: A Qualitative Synthesis Within A Systematic Review, Ismaeel Yunusa, Tarilate Temedie-Asogwa, Osaro Mgbere, Julie Atta, Moosa Tatar, Susan Abughosh, Ekere Essien

Posters

Background: Despite the availability of effective HIV prevention strategies, including pre-exposure prophylaxis (PrEP), gaps in prevention delivery persist across healthcare settings. Missed opportunities for HIV prevention remain common, yet multilevel factors driving these gaps are not fully understood. Understanding these drivers is essential to inform effective interventions at the individual, interpersonal, provider, and system levels. Objectives: To identify and synthesize multilevel determinants of missed opportunities for HIV prevention and PrEP delivery. Methods: We conducted a qualitative synthesis within a systematic review of U.S.-based studies (2012-2025) on missed opportunities for HIV prevention. Articles were identified through database searches (PubMed, Embase, and …

Comparative Effectiveness Of Augmentation, Switching, And Dose Escalation After Inadequate Antidepressant Response In Medicare Beneficiaries, Chih-Ting (Tim) Lai, Jingjing Qian, Cherry Jackson, Kimberly Garza, Jingyi Zheng, Richard Chapman, Surachat Ngorsuraches

Podiums

Objective: To evaluate the comparative effectiveness of treatment augmentation, switching, or dose escalation for inadequate treatment response among patients living with depression. Methods: We conducted a retrospective cohort study using data from the Medicare Current Beneficiary Survey(MCBS; 2016-2022). We identified beneficiaries with depression who had both survey responses and had at least one antidepressant claim record 6 months before the outcome assessment. We excluded patients diagnosed with bipolar disorder, schizophrenia, and other psychotic disorders. Patients with evidence of treatment resistance, determined by using 3 or more antidepressants, or any antipsychotics at baseline, were also excluded. The primary outcome was the …

Main-Chain Ion-Pair Polybenzimidazole Membranes Enabling Reduced-Temperature Ht-Pemfc Operation (Down To 120°C), Brian C. Benicewicz, Huina Lin

Faculty Publications

Proton exchange membrane (PEM) fuel cells are promising for clean and efficient energy conversion across diverse applications. High-temperature PEM fuel cells (HT-PEMFCs) using phosphoric acid (PA)-doped polybenzimidazole (PBI) can operate up to 200°C, but at lower temperatures, water-induced PA loss often leads to performance degradation and reduced durability. In this work, we present a new class of main-chain ion-pair PBI membranes by integrating the imidazolium-biphosphate ion-pair units directly into the PBI backbone. This design results in membranes with high acid content, stronger acid-polymer interactions and stabilized acid retention. In single-cell tests, the Im+-PBI15-3 wt.% exhibits peak power densities of 0.79 …

Understanding Parents Perceptions Concerning Division I Student-Athlete Mental Health, Jonathan M. Casper, Jason Bocarro, Marie Amidon

Journal of Issues in Intercollegiate Athletics

Collegiate student-athletes (SAs) frequently underreport mental health concerns and are less likely to seek professional support compared to their non-athlete peers. Given the substantial emotional and academic support parents provide, this study examined NCAA Division I parents’ perceptions of their student-athletes’ mental health and overall well-being, as well as their awareness and perceptions of available mental health services. An online survey (N = 178) was administered across two Division I universities. Parents reported considerable concern regarding mental exhaustion, anxiety, academic pressures, and future planning. They also identified sport-specific stressors, including relationships with coaches, playing time, team dynamics, and injuries. Although …

The 2026 Sc Administrator Working Conditions Survey, Angela Starrett, Brian Cartiff, Svetlana Dmitrieva

Reports

The SC Administrator Working Conditions Survey (SCAWCS) was developed to systematically examine the work environments of school leaders. Grounded in the job demands-resources (JD-R) model, the survey conceptualizes administrator working conditions as a balance between the demands of the role and the resources available to support it. The JD-R framework emphasizes that high job demands, such as workload and accountability pressures, can contribute to stress and burnout when not sufficiently offset by job resources. In contrast, robust resources can buffer these demands and promote engagement, resilience, and long-term commitment to the profession. Designed by SC TEACHER, the SCAWCS measures 13 …

White Matter Microstructure Of Sensorimotor Projection Fibers In Chronic Low Back Pain, John R. White, Jennifer M.C. Vendemia, Zachary Baty, Sheri Silfies, Stephen A. Coombes

Faculty Publications

Introduction: 

Chronic low back pain (cLBP) is linked to altered cortical sensorimotor structure and function, yet white matter microstructure in sensorimotor projection fibers remains poorly characterized. Objective: To address this gap, we used diffusion MRI to comprehensively characterize sensorimotor projection fibers in 44 patients with cLBP and 41 matched healthy controls.

Methods: 

We estimated an array of microstructural measures, including fractional anisotropy (FA), extracellular free water fraction (FW), free water–corrected FA (fwcFA), and neurite orientation dispersion and density imaging (NODDI) metrics.

Results: 

General linear models identified significantly higher FA and fwcFA and lower orientation dispersion index (ODI) in cLBP vs …

SNP-disease associations were assessed within each cohort, followed by meta-analysis and false discovery rate (FDR) correction to identify significant disease-risk variants. P2RX7 mRNA and protein expression across tissues or cells …

Saag: Structured Agent Assessment And Grounding, Ritvik Garimella, Vedant Khandelwal, Anvi Kohli, Amit Sheth

Publications

Exact-match evaluation of agent-calling obscures qualitatively different failure modes: a model may select the right function yet hallucinate argument values, or satisfy a schema while choosing a agent for the wrong reason. Existing benchmarks collapse these distinctions into a single binary score, leaving practitioners unable to diagnose where agent calls fail. We propose SAAG a cascaded diagnostic framework that decomposes agent-calling evaluation into three sequential stages: registry conformance, structural completeness, and argument grounding, each producing interpretable stage-specific diagnostics. These diagnostics additionally enable iterative self-repair: on prediction failure, the stage-specific signal guides targeted correction without leaking ground-truth values. We evaluate this …

A Qualitative Analysis Of Reddit Posts Made By Formerly Incarcerated Women, Madison R. Diaz

Graduate Student Thesis

Women with felony convictions who serve prison sentences encounter significant barriers during reentry, making it difficult to achieve stability. These barriers are shaped by stigma, background check policies, and limited access to supportive resources, often leading to feelings of hopelessness and isolation. The current study analyzes Reddit posts made by self-identified women in the r/Felons subreddit to understand how they describe these barriers and how they use online spaces for support. A qualitative content analysis was used to identify common themes related to employment, education, housing, and stigma. Many posts reflect frustration, discouragement, and anger toward the criminal justice system …

Rgfc: Registry Grounded Function Calling With Stage-Decomposed Evaluation, Ritvik Garimella, Vedant Khandelwal, Anvi Kohli, Amit Sheth

Publications

Tool-calling evaluations often report whether the final call matches a reference answer, but this single outcome merges different failures: choosing a function outside the available registry, violating the selected schema, or filling arguments with values not supported by the user request. These failures matter more when models must choose from larger tool registries. We introduce RFCD, a registry-scaled function-calling benchmark built from BFCL, Glaive Function Calling v2, and Tool-Call-Data, with standardized JSON-schema registries ranging from 5 to 3,000 functions. We also introduce TAAG, a deterministic stage-decomposed evaluator for registry conformance, structural completeness, and argument grounding. Across six locally served sub-4B …

Searching For A Connection Between Intellectual Humility And Decision-Making Ability, Mansi Verma, Kristin Kirchner

Caravel Undergraduate Research Journal

The present study investigated whether there was a relationship between intellectual humility and decision-making. The participants were 32 undergraduate students recruited from the University of South Carolina. Data was collected through self-reported measures of intellectual humility from the participants and their answers to questions testing for decision-making ability in a single survey. Results indicate that there is a correlation between the scores on the Intellectual Humility Scale and CRT scores. Overall, there does appear to be a relationship between intellectual humility and decision-making.

Examining Biobehavioral Indicators Of Adhd In Children With Fxs, Hannah Pressler, Kayla Smith, Ramsey Coyle, Elizabeth Will, Jane E. Roberts

Caravel Undergraduate Research Journal

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention and hyperactivity/impulsivity behaviors that are inconsistent with developmental age. Children with fragile X syndrome (FXS), a genetic neurodevelopmental disorder, are often diagnosed with comorbid ADHD (53–59% of males with FXS). Despite the prevalence of ADHD in FXS, little is known about the early manifestation of ADHD. The current project aims to explore group differences in play behaviors between children with FXS and typically developing (TD) children as well as the relationship between infant play behavior and heart activity to future ADHD attention outcomes. Participants included male children with FXS and …

Optimizing Expression Conditions For The Overexpression Of Iron Regulatory Protein Bol2 From C. Glabrata, Jade Ikahihifo-Bender, Dr. Caryn Outten, Mrs. Evan Talib

Caravel Undergraduate Research Journal

Due to its unique ability to serve as both an electron donor and acceptor, iron is utilized as a co-factor for many biological processes, including electron transfer, oxygen binding, and vitamin synthesis. Iron is also a key factor during fungal infections as the human host and invading pathogens battle over limited iron pools. The primary iron-responsive transcription factor Aft1 in the opportunistic pathogenic yeast Candida glabrata responds to iron deficiency by activating expression of iron acquisition genes. However, the mechanisms for sensing intracellular iron levels and regulating Aft1 activity in response to iron are unknown. The C. glabrata iron regulation …

The Effects Of Eating Disorder Knowledge On Dieting Beliefs, Kaitlyn Finn, Melanie Palomares, Kristin Kirchner

Caravel Undergraduate Research Journal

The study at hand was designed to look into the issues of eating disorder awareness and dieting attitudes. Specifically, it was hypothesized that individuals with more knowledge of eating disorders would be less likely to believe in dieting. It was additionally hypothesized that there would be a difference in amount of eating disorder knowledge seen between pre-determined age groupings. This was hypothesized due to the nature of the inception of eating disorders as a clinical diagnosis. Eating disorders did not begin to be added as a category into the Diagnostic and Statistical Manual until the 80’s, suggesting that participants of …

Dominance Linearity And Steepness In Captive Western Lowland Gorillas, Nate Wichmann

Caravel Undergraduate Research Journal

Many animals live in social groups for a variety of reasons, whether it is for hunting strategies, predator avoidance, or enhanced resource acquisition. These groups often develop a social network and/or dominance hierarchy within the population, with certain individuals gaining advantages or disadvantages based upon one’s rank within a group. Dominance hierarchies can be assessed on the grounds of structure, and, more recently, steepness.  Structure can be assessed by determining and comparing the rank of each individual (quantified by David’s scores). These scores can then be plotted and analyzed to determine the steepness of the dominance hierarchy. A dominance hierarchy …

Early Behavioral And Physiological Predictors Of Autism In 12-Month-Old Siblings Of Children With Autism, Nicolas Poupore, Kayla Smith, Abigail L. Hogan, Jane E. Roberts Ph.D.

Caravel Undergraduate Research Journal

Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined by social-communicative deficits and repetitive behaviors. Complementing behavioral (i.e., The Autism Observation Scale for Infants (AOSI) scores) and physiological markers (i.e., respiratory sinus arrhythmia (RSA), heart rate (HR)) may improve early identification of ASD and provide insights into the neurobiological mechanisms contributing to early ASD symptoms. Younger siblings of a child with ASD (ASIBs) had significantly higher AOSI Total Scores and AOSI Marker Scores in comparison to Low Risk Controls (LRCs). RSA significantly decreased from a Baseline to AOSI for both groups, but only for the ASIB group was a negative …

Extending The “Pepsi Paradox” To Diet Cola, Charlotte Schallenberg, Melanie Palomares

Caravel Undergraduate Research Journal

Since the invention of cola, the rivalry between Pepsi and Coca-Cola (i.e., Coke) has been in existence. Coke has been the preferred brand over all other colas, despite the preference for Pepsi in blind taste tests. This has been coined as the “Pepsi Paradox.” In the current study, we evaluated the “Pepsi Paradox” in both regular and diet cola. We entertained the possibility that preferences for cola brands would be roughly equivalent in South Carolina since it borders North Carolina and Georgia, the state of origin of Pepsi and Coke, respectively. The data showed that most people stated they preferred …
