The Devil Is In The Det[Ai]Ls: Ai Agents, Ghost Students, And The Crisis Of Verified Presence In An Agentic Ai World, Aras Bozkurt, Helen Crompton, Caroline Fell Kurban

STEMPS Faculty Publications

The transition from reactive Generative Artificial Intelligence (GenAI) to agentic AI systems marks a categorical shift in digital education, moving beyond simple content generation to goal-oriented, autonomous execution. This paper explores the emergence of the “ghost student”: a digital surrogate created by the coupling of Large Language Models (the “mind”) and agentic AI browsers (the “body”). These entities are capable of navigating Learning Management Systems (LMS), engaging with content, and completing assessments with human-like mimicry, often rendering the actual learner’s presence optional. We argue that this phenomenon creates a verification gap that traditional proctoring and detection tools are structurally unable …

Instructional Designers' Reflections On Generative Ai Use For Scenario-Based And Performance-Centered Learning: A Collective Autoethnography, Nour El Houda Maache, Dan V. Dao, Jiyoon Jung, Jayanth Nadheri, Nari Kim, Chikezie Ozuzu, Xinyue Ren

STEMPS Faculty Publications

This study examines how instructional designer-instructors (IDIs) use and evaluate generative artificial intelligence (GenAI) when designing scenario-based and performance-centered authentic learning in higher education. Using a collective autoethnography (CAE) approach, the study draws on semi-structured interviews and reflective narratives from five IDIs with varied professional experience. Findings indicate that GenAI enhanced design capacity by accelerating scenario development, translating complex content, and supporting scenario-based and performance-based task construction. At the same time, participants reported limitations related to contextual misalignment, output unreliability, and the cognitive demands of prompt refinement. Across cases, effective integration depended on sustained human oversight, disciplinary judgment, and ethical …

Chatgpt In Secondary English Language Learning: Educators' And Students' Literacy, Perceptions, And Experiences, Victoria Brenes, Sierra Outerbridge, Xinyue Ren

STEMPS Faculty Publications

The increasing use of generative artificial intelligence (GenAI) has shown the potential of transforming teaching and learning practices in various educational settings, such as in English language learning (ELL). As English language learners (ELLs) often experience many challenges and barriers in schools in the United States, it is urgent to leverage the educational affordances of GenAI in fostering the effectiveness of ELL. Given the limited research investigating GenAI adoption, especially ChatGPT literacy within K-12 ELL, this convergent mixed methods research aims to investigate students' and teachers’ perceptions of using ChatGPT and their ChatGPT literacy in secondary ELL contexts. We will …

A Two-Stage Changepoint-Copula Framework For Non-Stationary Count Time Series: Application To Tropical Cyclones, Md Iqbal Hossain, Norou Diawara

Mathematics & Statistics Faculty Publications

Cross-basin tropical cyclone variability may exhibit complex, non-linear dependence structures influenced by large-scale climate modes and potential regime shifts. Reliance on traditional linear correlation measures without accounting for structural changes can therefore lead to misleading interpretations of global storm relationships. This study investigates the regional dependence structures of tropical cyclone counts across six major ocean basins (NA, ENP, WNP, NI, SI, and SP) from 1980 to 2024. We adopt a two-stage analytical framework integrating changepoint detection and copula modeling to address non-stationarity in both marginal distributions and dependence structures. First, we identify a significant structural break in the year 2000 …

Climate Change Impacts On Hydrology In The Upper James Watershed, Imiya Mudiyanselage Chathuranika, Dalya Ismael

Engineering Technology Faculty Publications

Hydrological modeling of the Upper James Watershed (UJW), Virginia, is critical for predicting water availability, flood management, agriculture, ecosystem protection, and hydropower production under increasing climate change. The Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) is applied to evaluate climate change impacts on key hydrological components within the watershed. Future climate conditions were assessed for the near (NF: 2026-2050), mid (MF: 2051-2075), and far (FF: 2076-2100) periods using three Global Climate Models (GCMs) under Shared Socioeconomic Pathways SSP 2-4.5 and SSP 5-8.5. Climate data were bias-corrected using the Linear Scaling Method (LSM) and used to drive the HEC-HMS model. Results project …

Assessing Climate Change Impacts On Wildfire Risk In Central Appalachian Forests Of The Eastern United States, Imiya Mudiyanselage Chathuranika, Dalya Ismael

Engineering Technology Faculty Publications

Wildfire risk is increasing in the eastern U.S., yet spatial and climate-driven assessments remain limited. This study evaluates climate change impacts on wildfire risk in the Upper James Watershed (UJW) using baseline (2000–2019), near-future (2021–2040), and far-future (2061–2080) projections from a 12-model CMIP6 global climate model (GCM) ensemble under SSP2–4.5 and SSP5–8.5. A wildfire risk model was developed in ArcGIS Pro using nine key factors and validated with MODIS hotspot data, showing good agreement between modeled risk patterns and observed fire occurrences (NOF = 0.21, RMSE = 4.20, MAE = 3.37). Baseline risk was primarily driven by land cover, fire-lookout …

Improving Medical Diagnostics With Vision-Language Models: Convex Hull-Based Uncertainty Analysis, Ferhat Ozgur Catak, Murat Kuzlu, Taylor Patrick, Michel Audette

Engineering Technology Faculty Publications

In recent years, vision-language models (VLMs) have been applied to various fields, including healthcare, education, finance, and manufacturing, with remarkable performance. However, concerns remain regarding VLMs’ consistency and uncertainty, particularly in critical applications such as healthcare, which demand a high level of trust and reliability. This paper proposes a novel approach to evaluate uncertainty in VLMs’ responses using a convex hull approach on a healthcare application for visual question answering (VQA). For any VLM, temperature refers to a sampling parameter used in probabilistic generation, which controls the randomness of the model’s output. The LLM-CXR model is selected as the medical …

Nanosecond Pulsed Electric Fields For Extracellular Vesicle Engineering: From Electro-Exocytosis To Cargo Modulation, Art Neal, Teresa Graham, Mohamadmahdi Samandari, Arash Ghorbannia, Anca Dobrian, Stephen J. Beebe, Ruben M. L. Colunga-Biancatelli

Bioelectrics Publications

Extracellular vesicles (EVs), including small extracellular vesicles (sEVs) and medium/large extracellular vesicles (MVs), have emerged as promising therapeutic vectors and diagnostic biomarkers across various branches of biomedicine. However, the clinical translation of EV-based technologies remains constrained by persistent challenges in manufacturing: insufficient yield from primary cell sources, limited control over cargo composition, and the absence of scalable, standardized production platforms. Nanosecond pulsed electric fields (nsPEF) represent an emerging biophysical approach that can address several of these limitations. Unlike conventional electroporation, which targets the plasma membrane using microsecond-to-millisecond pulses, nsPEF delivers ultrashort (1–300 ns), high-amplitude (10–300 kV/cm) pulses that penetrate intracellularly …

Mg-Spair: Multi-Grade Sparse-Guided Implicit Representation For Training-Data-Free Image Restoration, Jianmin Liao, Lei Huang, Ronglong Fang, Ashley Prater-Bennette, Lixin Shen, Yuesheng Xu

Mathematics & Statistics Faculty Publications

MG-SpaIR is a training-data-free framework for restoring a clean image from a single observation corrupted by a mixture of blur, downsampling, noise, and missing pixels. Building on implicit neural representations (INRs), we introduce a multi-grade residual hierarchy that progressively refines the reconstruction from low to high spatial frequencies across grades, improving representational fidelity and mitigating spectral limitations. To stabilize reconstruction optimization and suppress INR-induced artifacts, we further propose an explicit sparse proximal regularization (e.g., ℓ0 type) applied directly in the high-resolution image domain, which discourages spurious high-frequency patterns while preserving sharp structures. The resulting optimization is solved efficiently via a …

High-Energy Η(′)Π Photoproduction And The Nature Of Exotic Waves, Glòria Montaña, Vincent Mathieu, Vanamali Shastry, Łukasz Bibrzycki, César Fernández-Ramírez, Nadine Hammoud, Robert J. Perry, Alessandro Pilloni, Arkaitz Rodas, Wyatt A. Smith, Adam P. Szczepaniak, Daniel Winney

Physics Faculty Publications

The observation of hybrid mesons in photoproduction experiments can provide essential insight into the inner workings of quantum chromodynamics in the strong coupling regime. In particular, the study of final η^(′)π states is of great interest due to the presence of the lowest lying hybrid candidate with manifestly exotic quantum numbers, the π₁ (1600). In this work, a double-vector exchange model with Reggeized ρ and ω trajectories is developed to describe the photoproduction of η^(′)π in the high-mass region. Results are presented for the differential cross sections and forward-backward asymmetries in the energy region of interest …

The electroproduction of η′ mesons from a ¹H target at W = 2.13GeV, Q² = 0.46(GeV/c)² and cos θ^CM_𝛾*η ≈ -1 has been experimentally measured. The differential cross section of virtual-photoproduction has been obtained as 4.4 ± 0.8(stat.) ± 0.4(sys.)nb/sr in the One-Photon-Exchange Approximation. This value is one-sixth of that of real-photoproduction at backward angles. A comparison with newly-developed isobar model calculations not only shows validity of the theoretical framewark employed, but also imposes new constraints on coupling strength between the η′p final state and nucleon resonances.

Measurements of semi-inclusive deep-inelastic scattering multiplicities for 𝜋⁺ and 𝜋⁻ from proton and deuteron targets are reported on a grid of hadron kinematic variables 𝑧, 𝑃𝑇, and 𝜙* for leptonic kinematic variables in the range 0.3< 𝑥< 0.6 and 3< 𝑄²< 5GeV². Data were acquired in 2018 and 2019 at Jefferson Lab Hall C with a 10.6 GeV electron beam impinging on 10-cm-long liquid hydrogen and deuterium targets. Scattered electrons and charged pions were detected in the High Momentum Spectrometer and Super High Momentum Spectrometer, respectively. The multiplicities were fitted for each bin in (𝑥,𝑄²,𝑧,𝑃_𝑡) to extract the 𝜙*—independent 𝑀₀ and the azimuthal modulations ⟨cos⁡(𝜙*)⟩ and ⟨cos⁡(2⁢𝜙*)⟩. The 𝑃_𝑡 dependence of the 𝑀₀ results was found to be remarkably consistent for the four cases studied: 𝑒⁢𝑝→𝑒⁢𝜋⁺⁢𝑋, 𝑒⁢𝑝→𝑒⁢𝜋^−⁢𝑋, 𝑒⁢𝑑→𝑒⁢𝜋⁺⁢𝑋, 𝑒⁢𝑑→𝑒⁢𝜋^−⁢𝑋 over the range 0GeV< 𝑃_𝑡< 0.4GeV, as were the multiplicities evaluated near 𝜙*=180∘ over the extended range 0GeV< 𝑃_𝑡< 0.7GeV. The Gaussian widths of the 𝑃𝑡 dependence exhibit a quadratic increase with 𝑧. The cos⁡(𝜙*) modulations were found to be consistent with zero for 𝜋⁺, in agreement with previous world data, while the 𝜋⁻ moments were, in many cases, significantly greater than zero. The cos⁡(2⁢𝜙*) modulations …

Unpolarized Gpds At Small X And Non-Zero Skewness, Yuri V. Kovchegov, M. Gabriel Santiago, Huachen Sun

Physics Faculty Publications

We study the small-x asymptotics of unpolarized generalized parton distributions (GPDs) and generalized transverse momentum distributions (GTMDs). Unlike the previous works in the literature, we consider the case of non-zero (but small) skewness while allowing for non-linear contributions to the evolution equations. We first show that unpolarized GPDs and GTMDs at small x are related to the eikonal dipole amplitude N, whose small-x evolution is given by the BK/JIMWLK evolution equations, and to the odderon amplitude 𝒪, whose evolution is also known in the literature. We then show that the effect of non-zero skewness ξ ≠ 0 is to modify …

Extracting accurate results from neutrino oscillation and cross section experiments requires accurate simulation of the neutrino-nucleus interaction. The rescattering of outgoing hadrons (final state interactions) by the rest of the nucleus is an important component of these interactions. We present a new measurement of proton transparency (defined as the fraction of outgoing protons that emerge without significant rescattering) using electron-nucleus scattering data recorded by the CLAS detector at Jefferson Laboratory on helium, carbon, and iron targets. This analysis uses a new data-driven method to extract the transparency. It defines transparency as the ratio of electron-scattering events with a detected proton …

Studying Electroweak Few-Body Observables In Chiral Effective Field Theory, Alex Gnech

Physics Faculty Publications

The use of nuclei to study electroweak probes is becoming increasingly relevant experimentally. The success of dark matter and neutrino experiments strongly depends on the ability to control nuclear effects in order to extract the fundamental parameters associated with external probes. Therefore, reliable theoretical calculations of nuclear structure and reactions, with well-controlled errors, are crucial for the success of experimental efforts. Currently, chiral effective field theory (χEFT) coupled with {\it ab-initio} methods represents one of the best approaches that fulfills these requirements. To use this approach as a tool for studying fundamental physics, it is essential to validate it against …

How To Create Accessible Osce Exams For Learners With Disabilities, Lisa M. Meeks, Jordan Juliao, Emily Langham, Anne Lewis, Judith Brenner

University Administration Publications

[Introduction] Objective structured clinical examinations (OSCEs) are widely used across health professions education to assess learners' clinical skills through structured encounters with standardised patients [1]. OSCEs also present a known barrier to disability access for medical students with disabilities [2-6], a rapidly growing population. Using trained actors, also known as standardised patients who portray the same clinical scenario for all learners, these examinations allow for assessment of medical knowledge, clinical reasoning, communication skills and elements of the physical examination in a controlled and standardised setting [1]. They may be used for formative feedback, summative assessment or progression decisions, and they …

Lgbtq People's Experiences With Crime, Victimization, And The Criminal Legal System, Vanessa R. Panfil

Sociology & Criminal Justice Faculty Publications

The ebb and flow of social control efforts aimed at LGBTQ people necessitate a thorough investigation into their experiences. This review of the literature is organized around four key themes that characterize LGBTQ people's experiences with crime, criminalization, victimization, and the criminal legal system—including police, courts, and carceral facilities. LGBTQ people experience excessive rates of arrest and incarceration and have higher rates of victimization, which illustrate disproportionality. Their experiences differ from those of their cisgender and heterosexual counterparts and are conditioned by age, race, class, gender, and sexual orientation, illustrating intersectionality. The two primary, interrelated mechanisms driving LGBTQ criminalization and …

Revisiting The Rural Folk Devil: Rural 'Othering' And The Connections Between Media Stereotypes And Rural Issues, Brooke Baker, Ida L. Oesteraas, Stephen T. Young, Elizabeth Monk-Turner

Sociology & Criminal Justice Faculty Publications

The current study is a discourse analysis investigating anti-idyllic cinematic representations, specifically in the horror genre, of rural people, places, and cultures. Findings reveal that anti-idyllic images and discourses are prominent within recently released horror films, which rely heavily on framing rural people as the deviant “other.” Special attention is given to the cultural work of these stereotypical depictions and the associated social harms for rural communities. Specifically, we argue that (1) corporations, particularly film companies, contribute to social harm in rural areas by disseminating negative and anti-idyllic representations; (2) these portrayals have tangible and detrimental effects on both people …

Understanding Homicide Dynamics: The Role Of Victim-Offender Relationships And The Event Circumstances Across Demographic Groups, Avdi S. Avdija, Christian W. Gallagher, Devere D. Woods Jr., Arif Akgul

Sociology & Criminal Justice Faculty Publications

This study investigates how the victim-offender relationship relates to the circumstances under which homicides occur, with the main focus on variations within gender, race, and age categories. To achieve these research objectives, we analyzed over forty years of data from the FBI's Supplementary Homicide Reports (1976-2017), reported by the U.S. Law Enforcement Agencies. The findings that emerged in this study show that offenders are more likely to kill victims of the same gender when taking into account the victim-offender relationships. Furthermore, this study shows that black offenders are more likely to kill acquaintances and intimate partners whereas white offender demonstrated …

Lost In The Language: Data Breaches And The Strategic Fog Of Risk Disclosures, Ling Tuo, Shipeng Han

Accounting Faculty Publications

This study examines whether firms strategically adjust the readability of Item 1A (“Risk Factors”) disclosures following data breaches. Using U.S. firm-year observations from 2006 to 2023, we find that data breaches are associated with a significant decline in Item 1A readability. This decline is not accompanied by a meaningful increase in informational content; instead, post-breach disclosures exhibit higher syntactic complexity, more positive tone, and lower textual similarity to prior and industry peers' filings, consistent with strategic obfuscation rather than transparent reporting. The readability decline is amplified among firms facing higher litigation risk but attenuated among firms with stronger reputations for …

Maternal Child Maltreatment And Intimate Partner Violence: Effects On Perceptions Of Infant Temperment And The Mediating Role Of Emotion Regulation And Responsiveness, Jewelian N. Fairchild, G. Anne Bogat, Amy K. Nuttall, Alytia A. Levendosky, Joseph S. Lonstein, Maria Muzik

Psychology Faculty Publications

Purpose

Maternal adverse experiences, such as maltreatment in childhood and later intimate partner violence (IPV) during pregnancy, can disrupt the mother-child relationship and influence maternal perceptions of infant temperament. The present study explored how these adversities influence mothers’ views of their infants’ temperaments and examined the role of maternal emotion regulation and responsiveness to their infants as mediators of these relationships.

Methods

Using data from a longitudinal study of highly stressed, vulnerable women, 355 mothers retrospectively reported on their own childhood maltreatment, as well as their experiences of IPV and emotion regulation during pregnancy. Maternal responsiveness was coded using mother-infant …

Psychology Faculty Publications

Background: Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD), which are moderately heritable, frequently co-occur and contribute to significant public health burdens, particularly among economically disadvantaged urban communities. There are noted sex differences in PTSD and AUD outcomes, with evidence suggesting women have heightened susceptibility to stress-related alcohol use. Preliminary PTSD-AUD ecological momentary assessment (EMA) findings support bidirectional associations across clinical outcomes. However, no studies to date have used PTSD-AUD comorbidity models as organizing frameworks to examine the temporal ordering and stability of within-person symptom dynamics underlying the maintenance or exacerbation of PTSD and AUD symptoms, including bidirectional and …

Examining The Factor Structure And Subgroup Invariance Of The Deliberate Denial Of Disordered Eating Behaviors Scale, Lindsay Howard, Sage Hawn, Kayla D. Pitchford, Riley Mcgrath, Aubri Farniok, Arturo Sesma, Kristin E. Heron

Psychology Faculty Publications

The denial, concealment, or omission of disordered eating behaviors has received limited attention in the eating disorder literature, partly due to the lack of reliable and valid measures. This study re-examined the factor structure of the Denial of Disordered Eating Behaviors Scale (DDEBS-12) and tested measurement invariance across gender identity, racial identity, and levels of disordered eating in a non-clinical undergraduate sample (N = 3285). Confirmatory factor analyses did not support the original unidimensional structure. Instead, a seven-item model assessing denial of dietary restriction demonstrated the best fit and was renamed the DDEBS-restriction. The revised scale showed good internal consistency …

Early Parenting Stress And Later Abuse Risk: Dyadic Analysis Of Mediation By Maternal And Paternal Negative Attributions, Jewelian N. Fairchild, Christina M. Rodriguez

Psychology Faculty Publications

Predicting the likelihood parents will become physically abusive towards their children remains a high priority.
