Maximum Spread Of KS,T - Minor-Free Graphs, William Linz, Linyuan Li, Zhiyu Wang

Faculty Publications

The spread of a graph G is the difference between the largest and smallest eigenvalue of the adjacency matrix of G. In this paper, we consider the family of graphs which contain no K_s,t-minor. We show that for any t ≥ s ≥ 2 and sufficiently large n, there is an integer ξ_t such that the extremal n-vertex K_s,t-minor-free graph attaining the maximum spread is the graph obtained by joining a graph L on (s − 1) vertices to the disjoint union of ⌊(2n + ξ …

How Agency From Precollege Experiences Empowers Black Student-Athletes To Succeed And Find Belonging At Pwis: A Phenomenological Study, Deborah V. Hogan

Journal of Issues in Intercollegiate Athletics

In the ever-changing college football landscape, Division I (DI) student-athletes seek to maximize their athletic and financial potential while navigating the academic and social challenges of college life. For Black student-athletes (BSAs) at predominantly White institutions (PWIs), the campus racial climate shapes their college experience and sense of belonging. The current phenomenological study explores how DI Black football student-athletes (BFSAs) use agency from precollege experiences to navigate racial climates and find belonging at PWIs. Using Critical Race Theory (CRT) and sense of belonging frameworks, semi-structured interviews were conducted with 13 former BFSAs from DI PWIs. The study revealed three main …

Co-Development Of A Gamified Physical Education Movement Competence Intervention With School Stakeholders, Jenna Rice, Lawrence Foweather, Jonathan Foulkes, Ceriann Magill, An V. De Meester, David F. Stodden Ph.D., Matthieu Lenoir, Katie Fitton Davies

Faculty Publications

Movement competence (MC) and emotional intelligence (EI) are positively associated and important for child development. Intervention research is needed to determine causal relationships between these outcomes. Gamification is a pedagogical model that may enhance MC and EI, but implementing interventions in schools is complex and requires multi-stakeholder involvement to ensure feasibility, acceptability and sustainability. However, methodological evidence to inform co-development work within physical education (PE) is lacking and further research is required. This study describes the process of co-developing a gamified PE intervention with school stakeholders to increase MC and EI among primary-aged children. A total of 91 children and …

A Survey On Food Ingredient Substitutions, Hyunwook Kim, Revathy Venkataramanan, Amit P. Sheth

Publications

Diet plays a crucial role in managing chronic conditions and overall well-being. As people become more selective about their food choices, finding recipes that meet dietary needs is important. Ingredient substitution is key to adapting recipes for dietary restrictions, allergies, and availability constraints. However, identifying suitable substitutions is challenging as it requires analyzing the flavor, functionality, and health suitability of ingredients. With the advancement of AI, researchers have explored computational approaches to address ingredient substitution. This survey paper provides a comprehensive overview of the research in this area, focusing on five key aspects: (i) datasets and data sources used to …

Budvari, Heather L. Mcdaniel, Antonio A. Morgan-López, Rashelle J. Musci, Jason T. Downer, Nicholas S. Isalongo, Catherine P. Bradshaw

Faculty Publications

Retention of early career teachers is a critical issue in education, with burnout and self-efficacy serving as important precursors to teachers leaving the field. An integration of the PAX Good Behavior Game (GBG; Barrish et al., 1969) and MyTeachingPartner (MTP; Allen et al., 2015) was tested in a randomized controlled trial (RCT) to investigate whether the combined programs would improve long-term outcomes for early career teachers. However, due to the COVID-19 pandemic, there was a higher proportion of missing data and attrition in follow-up data collection than otherwise would have been expected. The current paper focused specifically on …

Metabolism Of Co And H2 By Pioneer Bacteria In Volcanic Soils And The Phyllosphere, Nicola Fantom, Robin A. Dawson Phd, Rn, Cpnp-Pc, Edina Prondvai, Philippe Constant, Gary M. King, Hendrik Schäfer, Marcela Hernández

Publications

Trace gas degradation is a widespread metabolic adaptation in microbial communities, driving chemosynthesis and providing auxiliary energy that enhances persistence during nutrient starvation. In particular, carbon monoxide and hydrogen degradation can be of crucial importance for pioneering microbial communities colonising new, oligotrophic environmental niches, such as fresh volcanic deposits or the aerial interface of the phyllosphere. After volcanic eruptions, trace gas metabolism helps pioneer colonisers to initiate soil formation in ash deposits and on recently solidified lava, a vital ecosystem service. Similarly, in the phyllosphere, bacteria colonising newly emerging leaves and shoots, and/or persisting on the oligotrophic surface of plants, …

Exploring The Potential Of Large Language Models For Assisting With Mental Health Diagnostic Assessments: The Depression And Anxiety Case, Kaushik Roy, Harshul Surana, Darssan Eswaramoorthi, Yuxin Zi, Vedant Palit, Ritvik Garimella, Amit Sheth

Publications

Large language models (LLMs) are increasingly attracting the attention of healthcare professionals for their potential to assist in diagnostic assessments, which could alleviate the strain on the healthcare system caused by a high patient load and a shortage of providers. For LLMs to be effective in supporting diagnostic assessments, it is essential that they closely replicate the standard diagnostic procedures used by clinicians. In this paper, we specifically examine the diagnostic assessment processes described in the Patient Health Questionnaire-9 (PHQ-9) for major depressive disorder (MDD) and the Generalized Anxiety Disorder-7 (GAD-7) questionnaire for generalized anxiety disorder (GAD). We investigate various …

Faculty Publications

Objective

To compare healthcare services utilization across the healthcare system between frequent and non-frequent emergency department (ED) users among Medicaid enrollees in South Carolina.

Study Setting and Design

We conducted a retrospective, longitudinal study of individuals with at least one ED visit in 2017 in South Carolina and identified their healthcare services visits over 730 days (2 years) after their first ED visit. We classified individuals based on intensity of ED use: superfrequent (≥9 ED visits/year), frequent (4–8 ED visits/year), and non-frequent ED users (≤3 visits/year). We estimated differences between the three groups of ED users and non-ED hospital and …

The Blue Economy Comes To Green Creek, Ursula Ramsey

South Carolina Journal of International Law and Business

Oceans, touted as the “next great economic frontier,” are projected to contribute three trillion dollars to the global economy. Beyond their economic potential, oceans provide a host of environmental benefits: oceans supply over half of the planet’s oxygen and contain nearly all of the Earth’s water and biosphere. Especially because the high seas represent one of the few remaining global commons, oceans present a governance challenge. Meeting this challenge is the concept of the blue economy, a form of governance that combines environmental stewardship, economic development, and social equity. This article, in discussing Mulvihill v. South Carolina Department of Health …

The Efficacy And Usability Of Motivational Interviewing Just-In-Time Trainings For Youth Mentors, Mackenzie J. Hart, Samuel D. Mcquillin, Aidyn Iachini Ph.D., Msw, Lsw, Daniel K. Cooper, Mark D. Weist

Faculty Publications

Using youth mentors to deliver evidence-based psychosocial services has been proposed to increase the reach of treatments, in part given the affordability and ubiquity of mentors in youth settings. Further, tests of mentor-delivered motivational interviewing (MI) have shown increases in youth mentees' academic performance and wellbeing. Yet, traditional methods of training mentors to use MI can be costly and time-consuming. Previous work has suggested the value of asynchronous, brief, just-in-time training (JITT) to help offset these challenges; however, MI JITT for mentors has not yet been formally evaluated. As such, here, we report on a preliminary study of MI JITT …

Research Manuscript Series

This report covers the archaeological investigations at site 38BU1834, which falls within the boundary of the Charlesfort/Santa Elena National Historic Landmark on Parris Island, South Carolina. Initial investigations involved a search for activity areas associated with the Spanish pottery kiln discovered in 1993 near the golf course clubhouse. Later work on the site focused on a pond or sinkhole containing a deposit of World War I era U. S. Marine Corps trash and the prehistoric period earth and shell mounds that line the periphery of the pond/sinkhole.

Indirect Earnings Management, Scott B. Jackson, Jason T. Rasso, Aaron F. Zimbleman

Faculty Publications

We hypothesize that managers use their hierarchical role as reviewers of accounting judgments and estimates to manage earnings, which we call indirect earnings management (IEM). Across a series of experiments using highly experienced financial executives as participants, we provide evidence that IEM (1) is likely used by managers to achieve current and future earnings targets, (2) reduces both cognitive dissonance associated with managing earnings and the extent to which managers think that their behaviors constitute earnings management, and (3) is more likely to be used when corporate governance is strong than when corporate governance is weak. The results of this …

Permutations Minimizing The Number Of Collinear Triples, Joshua Cooper, Jack Hyatt

Faculty Publications

We characterize the permutations of Fq whose graph minimizes the number of collinear triples and describe the lexicographically-least one, confirming a conjecture of Cooper-Solymosi. This question is connected to Dudeney’s No-3-in-a-Line problem, the Heilbronn triangle problem, and the structure of finite plane Kakeya sets. We discuss a connection with complete sets of mutually orthogonal latin squares and state a few open problems primarily about general finite affine planes.

Media Effects On Political Confidence In Autocratic Regimes, Makayla M. Stokes, Matthew Placek

University of South Carolina Upstate Student Research Journal

In established autocracies, political control and support are integral to maintaining the regime. In an effort to do this, autocracies use media as a tool to persuade and manipulate public opinion in a favorable light. Negative media and messages are not tolerated as it threatens the legitimacy and continuation of the regime. The purpose of this study is to empirically evaluate the effects of social media and online news consumption on support for political institutions and overall satisfaction. This study will use hierarchical linear modeling to analyze data from the World Values Survey to test the hypothesis that social media …

Psychological Contract Breach And Institutional Trust In Higher Education: Extending The Triadic Framework, Hannah E. Blodget, Katelyn R. Raborn, Justin Travis, Susan Ruppel

University of South Carolina Upstate Student Research Journal

Psychological Contract (PC) theory, originally developed in organizational contexts, has increasingly been applied to higher education to understand the expectations and obligations that students perceive in their relationships with institutions. In this context, the PC refers to the unwritten set of mutual expectations and perceived obligations that shape the student-university relationship (Rousseau, 1998). Psychological contract breaches (PCB), or perceived failures to fulfill promised obligations, can undermine student trust, engagement, and institutional commitment. Despite growing interest, research on PCBs in higher education remains sporadic, often limited to cross-sectional designs, single relational targets, and inconsistent measurement approaches. Moreover, most studies focus on …
