ABO3 perovskite oxides are a versatile class of materials whose surfaces and interfaces play essential roles in sustainable energy technologies, including catalysis, solid oxide fuel and electrolysis cells, thermoelectrics, and energy-relevant oxide electronics. The interplay between point defects and surface reconstructions strongly affects interfacial stability, charge transport, and catalytic activity under operating conditions. This review summarizes recent progress in understanding how oxygen vacancies, cation nonstoichiometry, and electronic defects couple to atomic-scale surface rearrangements in representative perovskite systems. We first revisit Tasker’s classification of ionic surfaces and clarify how defect chemistry provides compensation mechanisms that stabilize otherwise polar or metastable …

What's That Sound?, Leslie Lemus
What's That Sound?, Leslie Lemus
Athena: Undergraduate Research and Literary Journal
"What’s That Sound?" is a metaphorical short story that explores racism through the lens of a mysterious, ever-growing sound. The protagonist begins to hear a strange noise, subtle at first, then increasingly deafening as they navigate daily life. Despite their confusion and efforts to understand the source, those around them, particularly white individuals, dismiss or deny the sound’s existence. Only other people of color acknowledge it, sharing a collective understanding. Through symbolism, the story illustrates how racism operates as an ever-present force felt deeply by marginalized communities, yet often ignored or unheard by those not directly affected.

Protecting The Debtor Across The Atlantic: A Comparative Analysis Of The United States And European Union Regulatory Frameworks Against Debt Collection Abuse And Harassment, Terin Michelle Tyson
South Carolina Journal of International Law and Business
Consumer debt is a long-standing global phenomenon, yet the regulation of debt collection practices remains fragmented across international borders. This lack of uniform standards leaves consumers vulnerable to debt collectors who exploit weak legal frameworks, resorting to abusive, harassing, and deceptive tactics to pressure repayment. Such practices not only undermine consumer trust in the financial services industry but also prove self-defeating; aggressive collection methods can destabilize a consumer’s financial footing and daily livelihood, ultimately impairing their capacity to repay.
This article provides a comparative evaluation of consumer protections against abusive and harassing debt collection practices in the United States and …

Black women in the United States face disproportionately high rates of maternal mortality, driven by structural racism, patient-provider mistreatment, and gendered and racial discrimination. However, little research has explored Black mothers’ perceptions of maternal health care services and structural racism in the Southeastern U.S. This study aims to address this gap by examining Black mothers’ maternal health care experiences in South Carolina. Using semi-structured interviews conducted during the summer of 2023 with Black mothers who had given birth within the previous five years, this qualitative study employed grounded theory to analyze recurring themes in their maternal health care experiences.

Perceived Use Of Web-Based Videoconferencing For Social Connectedness Among Older Adults Living In Long-Term Care: Qualitative Study, Anna Garnett, Halyna Yurkiv, Denise M. Connelly, Richard Booth, Lorie Donelle Phd, Rn, Fcan, Faan
Publications
Background:
The COVID-19 pandemic highlighted how restrictions on in-person interactions within long-term care homes (LTCHs) severely compromised social connectedness among older adults and their families. Post pandemic, despite policy changes supporting greater in-person family engagement, frequent outbreaks continue to disrupt face-to-face interactions, and factors such as geography, life circumstances, and health can constrain family members’ ability to make regular in-person visits. Research suggests that web-based videoconferencing technology (WVT) may be a practical solution to help older adults within LTCHs to maintain social connection in the absence of physical gathering. However, increased understanding of end user experience is lacking, and more …

Benefits And Harms Of Copyright Restrictions And Conditions On Burnout And Other Psychometric Assessment Scales, Robert G. Badgett, Sudha Xirasagar, Hayrettin Okut
Publications
INTRODUCTION: Copyright conditions can hinder the scientific and usage impact of essential assessment tools in healthcare, organizational psychology, and other fields. The stories of the Maslach Burnout Inventory (MBI) and the Mini-Mental Status Examination (MMSE) are well-documented. Despite decades-old recommendations to blend copyright restrictions of intellectual property when used for commercial purposes with permissive but distinct copyright terms for non-commercial and scholarly use, few authors of assessment tools do so.
OBJECTIVE
To assess whether restrictive copyrights limit the long-term scientific impact of copyright holders (often medical schools/faculty), by inhibiting downstream use, research, and improvement of measurement tools by other researchers. …

Mental And Physical Humanlikeness In Artificial Intelligence Influencers: Effects On Humanness, Eeriness, And Consumer Responses, Terry Kim Ph.D., Hyunjoo Im
Faculty Publications
Artificial intelligence (AI) influencers, nonhuman characters powered by AI, have garnered a significant following on social media in recent years. Through two between-subjects online experiments (n = 957), this study investigates the impact of AI influencers' appearance realism and self-disclosure on consumer perceptions (humanness and eeriness) and their downstream responses (intention to self-disclose, intention to follow the advice, and brand attitude). Drawing from anthropomorphism and theory of mind, this study emphasizes the distinction of two dimensions of AI influencers' humanlikeness (physical and mental) which differently affect the humanness and eeriness of the AI influencer. Results indicate that the AI …

Mineral-associated organic matter (MAOM) contains a substantial portion of soil nitrogen (N). MAOM-N could serve as an important N source for crops, but its availability and response to agricultural management across different soil types remains largely unknown. We characterized MAOM-N isolated from nine paired soils spanning a range of geochemical characteristics and maintained under two land uses—more intensively managed annual cropping systems or less intensively managed grasslands. On average, we found that MAOM contained approximately two-thirds of total soil N. Across all soil types, more intensive agricultural management resulted in a 50% decline in MAOM-N stocks, as well as a …

Background:
This study investigated the influence of belongingness, self-efficacy, and clinical learning support on readiness for nursing practice and explored the role of demographic factors and nursing program differences.Method:
A quantitative, descriptive approach was used to explore undergraduate prelicensure senior nursing students' perceptions across the United States.Results:
Descriptive statistics, Pearson correlation, and multiple linear regression demonstrated students in traditional Bachelor of Science in Nursing programs reported significantly higher scores across all domains compared with those in associate degree programs (p < .01). Similarly, students in programs with ≤400 clinical hours and those assigned only one preceptor scored significantly higher on all measures (p < .01 and p < .05, respectively). Regression analysis indicated self-efficacy and learning support explained 47.9% of the variance in practice readiness (p < .05).Conclusion:
These findings share how clinical experiences shape students' readiness for nursing practice. Recommendations …Toward Neurosymbolic Reinforcement Learning Via Editable Specifications, Vedant Khandelwal, Hong Yung Yip, Amit Sheth
Toward Neurosymbolic Reinforcement Learning Via Editable Specifications, Vedant Khandelwal, Hong Yung Yip, Amit Sheth
Publications
Reinforcement learning systems are commonly adapted to new settings by retraining or fine-tuning policies. This default is costly, difficult to audit, and poorly aligned with structured requirement changes such as revised safety rules, new operational constraints, or updated user preferences. We argue for an alternative abstraction: adaptation via edits to an external, human-readable specification that the agent consults at execution time. We propose conditioning decision-making on an editable knowledge graph encoding (i) rules capturing action applicability and high-level effects, (ii) hard constraints defining feasibility, and (iii) soft preferences shaping tradeoffs among feasible behaviors. Requirement changes become graph edits, not policy …

Cisheterosexism in LGBTQIA+ Health Resource Guides Vanessa Kitzie, Amirezza Kalantari, Olivia Reed University of South Carolina, School of Information Science [email protected] Limited healthcare resources lead many LGBTQIA+ people to peer networks, often accessed via search engines to find community-created health resource websites [1–3]. Academic library guides benefit privileged LGBTQIA+ identities [4], but little is known about community guides, which may reinforce cisheterosexist narratives, causing stigma and stress [5, 6]. This study addresses this gap by scraping Google results for LGBTQIA+ health resources across US states, examining how cisheterosexism shapes health topics, geography, and representation of LGBTQIA+ populations. We hypothesize that …

Governing By Fragments: Soviet Ruins And The Architecture Of Unaccountability In Kazakhstan, Robert A. Kopack, Magdalena E. Stawkoski
Faculty Publications
This article examines two case studies in Kazakhstan with research into how Soviet institutional legacies underwrite extractive economies that render toxic costs invisible in post-Soviet setting. Through ethnographic work in Stepnogorsk (uranium processing) and the Semipalatinsk Test Site (nuclear weapons testing), we extend Gabrielle Hecht’s residual governance framework to demonstrate how inherited bureaucratic compartmentalization now serves market rather than state interests. We introduce the concept of functional nonreform to describe how distributed actors maintain Soviet-era boundaries that prevent accountability: Agencies monitor but don’t enforce, health authorities lack jurisdiction over contaminated sites, and environmental agencies measure radiation but cannot restrict land …

Despite Malaysia's low leprosy prevalence, new cases continue to emerge in rural and Indigenous communities. National strategies often prioritise elimination and surveillance, while overlooking the needs and challenges of individuals affected by leprosy and those managing their care. This study employed a transdisciplinary research approach, guided by the Dialogue Model, to co-develop context-specific strategies to improve the lives of those affected through participatory engagement with both groups. Conducted across three high-burden states in Peninsular Malaysia, the research involved a desk review and stakeholder mapping, followed by 40 in-depth interviews with affected individuals and other stakeholders. These were complemented by a …
Nurses' Implicit Bias Toward Older Adults: A Mid-Range Nursing Theory, Jennifer T. May Phd, Rn, Anp-Bc, Hanne Dolan, Jessica G. Rainbow
Nurses' Implicit Bias Toward Older Adults: A Mid-Range Nursing Theory, Jennifer T. May Phd, Rn, Anp-Bc, Hanne Dolan, Jessica G. Rainbow
Publications
This article describes the development of the Nurses' Implicit Bias Toward Older Adults Mid-Range Nursing Theory, which explains how biased care arises and affects older adults. Drawing from Pepper's contextual-development worldview, Parse's Humanbecoming Paradigm, and an emancipatory perspective, the theory integrates implicit social cognition to explain how nurses' backgrounds and unconscious processes influence clinical practice. Key "mitigation points" are identified for targeted interventions to address bias. This framework provides a foundation for future research on implicit bias in nursing, with implications for equitable health care delivery and improved older adult patient outcomes, supporting the advancement of nursing science and professional …

Background:
Heavy metals, like lead, arsenic, and cadmium, are linked to increased inflammation even in early life; however, anti-inflammatory diets may offset these effects.
Methods:
We evaluated associations between heavy metals and inflammatory biomarkers, and potential effect modification by diet in 399 adolescents aged 10 to 18 at baseline who attended two study visits 2 years apart (773 observations). At baseline, blood lead, urinary arsenic, and cadmium concentrations were measured, and the Children’s Dietary Inflammatory Index (C-DII) was calculated. Fasting serum interleukin (IL)-4, IL-10, IL-1β, IL-6, IL-8, high-sensitivity C-reactive protein, and tumor necrosis factor-alpha were measured for both visits. Generalized …

We employ density functional theory calculations to investigate the energetics and diffusion mechanisms of alkali metal ions (Na+, K+, Rb+, and Cs+) within the analcime framework. While Na+preferentially adsorbs at the center of the 8-member ring, DFT calculations show that larger ions, such as Cs+, occupy the center of the cage due to steric constraints. The computed exchange energies indicate that exchange of Na+by Cs+is thermodynamically favorable. Migration energy barriers, determined using the climbing image nudged elastic band method, show that Na+is …

Mechanistic Roles And Design Criteria For Catalysts In Lithium–Sulfur Batteries, Saheed Lateef, Golareh Jalilvand
Faculty Publications
Catalysis is widely explored in lithium–sulfur (Li–S) batteries to address challenges related to limited capacity and cycle durability. Despite extensive research, catalyst development has often focused on materials without a clear understanding of the mechanistic landscape underlying the complex, multi-step, multi-electron sulfur redox pathway. In fact, our understanding of the thermodynamic, kinetic, and mass transport framework in Li–S systems is still evolving, particularly with respect to the reaction pathways during charge and discharge, and the dynamic evolution of materials in both liquid and solid phases. These evolving insights may fundamentally shift the requirements for catalyst design and future research priorities. …

Despite the wide application and benefits of the degree of rate control (DRC) analysis, several details remain argued, particularly about the conservation of DRCs at transient (TR) and steady-state (SS) conditions, especially for complex reaction networks. This work argues that previous proofs about the conservation properties of DRCs have been incomplete, and we provide new mathematical proofs at TR and SS conditions. In addition, we use both analytical (automatic differentiation) and numerical (finite difference) approaches to compute DRCs for the case study of ethane hydrogenolysis (EH) over Pt(111). This work confirms that at both TR and SS conditions, the sum …

Faculty Publications
A series of calcium rare earth silicate chlorides, CaLnSiO4Cl (Ln = Pr, Nd, Sm, Eu, Gd, and Tb), was obtained as single crystals from flux crystal growth. The structures were determined by single crystal X-ray diffraction and were found to be related to the spodiosite/Wagnerite mineral structure, Ca2PO4F. The obtained compositions are variations of the spodiosite structure that result from two simultaneous elemental substitutions. Replacing one calcium for one rare earth element and the simultaneous replacement of one VO43− or PO43− with one SiO44−. CaEuSiO4Cl was found to luminesce, and its photoluminescence spectrum is reported.

Water quality has traditionally been measured via in situ sensors and satellites. The latter has limited applicability for smaller inland water bodies, while the former requires significant logistics, labor, and expense for routine sampling, and reactive/spurious sampling is often not feasible as a result (e.g., sampling pre-/post-storm). Consequently, small uncrewed aircraft system-based (sUAS-based) sampling has emerged as a potential solution to bridge these sampling gaps and challenges. But sampling from an sUAS is complicated by the need to pump water from depth, rather than suspending a sensor from the sUAS, due to concern over sampling sUAS-impacted waters. Here, we measure …

Gibbs energy models necessary to describe the thermochemical behavior of cesium and iodine in molten FLiNaK (46.5LiF-11.5NaF-42KF mol%), a proposed molten salt reactor coolant and fuel solvent, have been developed as they are of concern due to their high radiotoxicity and volatility. The six constituent pseudo-binary systems LiI-CsI, LiI-KI, LiI-NaI, NaI-KI, KI-CsI and NaI-CsI were evaluated using available phase equilibria and mixing enthalpy measurements. The models for the ternary reciprocal salt systems Li,Cs|F,I, Li,K|F,I, Li,Na|F,I, Na,K|F,I, Na,Cs|F,I and K,Cs|F,I were obtained by interpolation of the optimized pseudo-binary systems and parameters fit as necessary based on observed behavior.

Consumers are increasingly conscientious of societal and environmental impacts of their purchases, prompting companies to make environmental, social, and governance (ESG) claims and engage in voluntary ESG assurance. However, prior literature lacks insight into whether consumers consider negative accounting news events (e.g., error/irregularity restatements) and their effects on purchasing intentions. Using real world consumers of sustainable goods, we investigate how varying levels of negative accounting news events (i.e., error or irregularity restatements), the presence of ESG product-quality assurance (e.g., cage free egg certification), and the type of assurance provider (e.g., an accounting firm that also audits the financial statements, an …
