Understanding Human Arm Stiffness Modulation In Overground Phri: The Roles Of Kinematics, Perturbation, And Trunk Sway, Mohsen Mohammadi Beirami, Sambad Regmi, Devin Michael Burns, Yun Seong Song

Psychological Science Faculty Research & Creative Works

This study examines human arm kinematics during overground physical human-robot interaction (pHRI). Previous work showed humans adjust arm stiffness with changing trajectory uncertainty, but the roles of arm kinematics and muscle activation remained unclear. Building on a preliminary study, we analyzed arm movements with more participants (10 individuals) to achieve more reliable findings and examined two potential influences that arose in the preliminary study: the robot's perturbation effect (a brief hand push) and left-to-right trunk sway. Using a linear mixed-effects model, we evaluated the effects of participant, block, and trajectory condition on arm angles. Results showed minimal kinematic contribution to …

Building Beyond The Classroom: A Qualitative Case Study On Enduring School-Community Partnerships In Deep East Texas, Christa Lacey

Electronic Theses and Dissertations

Schools across the United States face increasing challenges related to student achievement, equity, and engagement that extend beyond the classroom. School–community partnerships are frequently used to expand support systems for students; however, many collaborations remain short-lived or fragmented. The purpose of this qualitative collective case study was to explore the characteristics and conditions that contribute to successful and enduring school–community partnerships between public schools and the Boys & Girls Clubs of America (BGCA) in the Educational Service Center Region 7 of Texas. Guided by Social Capital Theory, Epstein’s Overlapping Spheres of Influence, and Distributed Leadership, this study examined how campus …

Expanding Public Health Insurance To Parents: Effect On Parents' And Children’S Well-Being, Michelle Marcus, Xuan Zhang

Research Collection School Of Economics

Expanding public health insurance to parents may not only improve parental outcomes but also have spillover effects on their children. This paper leverages the natural experiment of the Affordable Care Act (ACA) to estimate the causal effects of expanding public health insurance to low-income parents on their well-being and that of their children. Using a difference-in-differences model and data from the 2010–2017 National Health Interview Surveys, we observe significant improvements in health care access, increased health care utilization, reduced financial burdens, and slight improvements in health status among low-income parents. For children in Medicaid expansion states, we find reductions in …

China And International Economic Dispute Settlement: Disaggregating The State, Gregory Shaffer, Ji Li, Henry S. Gao

Research Collection Yong Pung How School Of Law

Most studies take a unitary state-centric approach to assessing China’s relationship with international economic law. In contrast, we provide a more nuanced approach that assesses variation in China’s engagement. We examine the role of different Chinese state and non-state actors, considering their interests, ideological frames, institutional contexts, and relation to state power. We illustrate our analytic framework by examining China’s response to and engagement with international dispute settlement systems in three areas: international commercial arbitration, international trade dispute settlement, and investor–state arbitration. Our approach is important for global cooperation in discrete policy areas so that the West does not ‘other’ …

Introducing The Aasspectq Framework: A New Typology For Assessing Quality, Pedagogy, Outcomes, And Learning In Micro-Credentials, Felix Quayson

Journal of Research Initiatives

Micro-credentials have gained increasing attention as a flexible and competency-based approach to bridging the gap between formal education and workforce demands. Unlike traditional qualifications and degrees, micro-credentials focus on discrete, demonstrable skills that can be rapidly developed, assessed, and recognized across industries. I proposed the Auditing, Avoidance, Specificity, Skills, Personalization, Efficiency, Competency, Technology, and Quality Assurance (AASSPECTQ) conceptual framework to examine the current state of micro-credential implementation, highlighting the tools, learning outcomes, and assessment instruments necessary for effective program design. The challenges of quality assurance, portability, and recognition that continue to limit widespread adoption were also explored. By …

Bespoke Realized Volatility: Tailored Measures Of Risk For Volatility Prediction, Andrew John Patton, Haozhe Zhang

Research Collection School Of Economics

Standard realized volatility (RV) measures estimate the latent volatility of an asset price using high frequency data with no reference to how or where the estimate will subsequently be used. This paper presents methods for “tailoring” the estimate of volatility to the application in which it will be used. For example, if the volatility measure will be used in a specific parametric forecasting model, it may be possible to exploit that knowledge to construct a better measure of volatility. We use methods from machine learning to estimate optimal “bespoke” RVs for heterogeneous autoregressive (HAR) and GARCH-X forecasting applications. We apply …

The Smu Trade Dashboard: Tracking And Quantifying The Trump Ii Tariffs, Pao-Li Chang, Ruoqing Chen, Lin Ma

Research Collection School Of Economics

The SMU Trade Dashboard (https://economics.smu.edu.sg/soetrade/tr ade-dashboard), developed by the SMU Center for Research on International Trade, consists of Tariff Tracker and Trade Simulation functions. The Tariff Tracker allows users to track the tariff applicable to an HS 6-digit product or an ISIC 2-digit sector bymarkets and country origins. The Trade Simulation presents quantitative simulation results of the effects of Trump II tariffs (and the associated tariff responses by its trading partners) on trade flows, welfare, and wages. This companion paper documents the methodologies underlying the tariff data collection protocol and the structuralsimulation designs.

Bridging 2d And 3d Computational Modeling Of Vacuum Arc Remelting: Capturing Rotating Arc Dynamics In Axisymmetric Simulations, Zilong Zhang, Elaheh Dorari, Ramesh Minisandram, Shakarjee Krishnamoorthi, Lang Yuan

Faculty Publications

Computational modeling of the Vacuum Arc Remelting (VAR) process has been developed to provide a deeper physical and metallurgical understanding and assist in the manufacture of defect-free ingots. While fully 3D, time-resolved arc models capture arc–melt interactions with high fidelity, their high computational cost makes 2D steady arc models still the preferred option in industrial applications. In this study, a multi-physics VAR model, which accounts for magnetohydrodynamics, heat transfer, fluid dynamics, and melting/solidification, was established in ANSYS Fluent for Alloy 718 in 3D with a rotating arc. It was validated against measured melt pool morphology. A new 2D axisymmetric oscillating …

Language Analysis Of "Gaslight" And "Narcissist" As Seen On Tiktok, Aaren Fernandez

Journal of Research Initiatives

TikTok is a popular social media platform from which users frequently obtain information. Specifically, psychological concepts such as anxiety, depression, and related conditions are becoming popular vernacular on TikTok through trends such as "story times." However, the accuracy of these terms' usage requires examination. In this qualitative analysis of TikTok posts and comments under the hashtags #gaslight and #narcissist, it was found that videos under these hashtags often originated from users attempting to warn viewers about psychological traits that align with common diagnostic language. However, comments under these videos tended to use these terms in a more casual sense than …

Methods: This retrospective cohort study included pediatric cancer patients (up to 18.99 years) presenting to the center over a 33.5-month period. Variables that could influence referrals to OT/PT were extracted from the electronic medical record (EMR) including OT and PT referrals (inpatient and outpatient), OT and PT consult completion, age at diagnosis, cancer type, sex, race/ethnicity, insurance, cancer treatment, …

Optimizing Feasibility And Acceptability Of An Online Expressive Writing Intervention For Survivors Of Adolescent And Young Adult Cancer: A Pilot Randomized Trial Of Iterative Modifications And Outcomes, Eunju Choi, Yusi Aveva Xu, Celia Cy Wong-Meli, Michael E Roth, Yisheng Li, Qian Lu

Faculty, Staff and Student Publications

Objective: To evaluate the feasibility of an online expressive writing (EW) intervention for survivors of adolescent and young adult (AYA) cancer and determine whether iterative, theory-driven modifications can enhance response, adherence, and completion rates.

Methods: In this randomized pilot trial, survivors of AYA cancer were recruited through a hospital-based AYA oncology clinic and an online community. Forty participants were randomly assigned to the EW intervention or control group. To improve on lower-than-expected adherence and completion rates in a previous cohort, the protocol was iteratively revised using the Framework for Reporting Adaptations and Modifications to Evidence-based Implementation Strategies (FRAME-IS). Modifications included …

Faculty, Staff and Student Publications

Breast surgery for aesthetic purposes, such as breast augmentation or breast reduction, and breast reconstruction after cancer treatment require an accurate structural (anatomical) and mechanical (functional) understanding of the breast components, including the fascial-ligamentous support system of the breast, to achieve optimal results. This paper aims to provide a comprehensive description of the mechanical behavior of the ligamentous and fascial connective tissues of the human female breast. Fasciae and ligaments obtained from 17 patients between 35 and 85 years of age who were undergoing mastectomy and three female cadavers were tested. Uniaxial tensile tests were conducted, and three constitutive models …

Faculty, Staff and Student Publications

Background and objectives: Preoperative imaging provides surgeons with an initial estimate of tumor infiltration and the likelihood of achieving an en-bloc resection in spinal cord ependymomas, yet the definitive decision is made intraoperatively. This study characterizes the intraoperative ultrasound (iUS) features that guide real-time surgical strategy and are associated with successful en-bloc removal.

Methods: A retrospective review of iUS images obtained during resection of spinal cord ependymomas was performed. The presence of a peritumoral halo representing the transition zone between the tumor and the spinal cord, the dorsal sagittal area of the spinal cord overlying the tumoral poles, the presence …

Pharmacokinetic Modeling Strategies For Dynamic Hyperpolarized Urea Imaging, Keith A Michel, Collin J Harlan, Christopher M Walker, Matthew E Merritt, Yunyun Chen, Stephen Y Lai, James A Bankson

Faculty, Staff and Student Publications

Purpose: To evaluate pharmacokinetic modeling methods for quantification of tissue perfusion/permeability with hyperpolarized 13C urea.

Methods: Three models for quantitative analysis of dynamic HP urea imaging data were proposed and evaluated in numerical simulations and a thyroid cancer mouse model. A multicompartment model resembling the extended Tofts model for DCE-MRI (Model I) and two simplified models were used. The simplified models each eliminate a volume parameter representing vascular (Model II) or impermeable cellular space (Model III). Signal curves were generated from Model I, and models were fit to these synthetic data to quantify the effects of acquisition settings, bias in …

Impact Of Cyp2d6 Metabolizer Status On Ondansetron Efficacy In Early Pregnancy Induced Nausea And Vomiting: A Case Control Study., Michelle Liu, Megan M. Shuey, Sabrina E. Holley, Darlene F. Fountain, James Jaworski, Carol Griffin, Jeewoo Kim, Melissa Stec, Sudeep D. Sunthankar, Henry H. Ong, Srushti Gangireddy, Wei-Qi Wei, Andrea Gaedigk, Digna R. Velez Edwards, Vivian K. Kawai

Manuscripts, Articles, Book Chapters and Other Papers

Real-world data investigating CYP2D6 on the efficacy of ondansetron for nausea and vomiting in pregnancy (NVP) is lacking. Evidence shows CYP2D6 ultrarapid metabolizers are at risk of ondansetron nonresponse due to increased metabolism. We conducted a retrospective cohort study of early pregnant patients on ondansetron for NVP. Genotype data for 11 CYP2D6 variants and copy number variations were translated into activity score (AS) and metabolizer status: poor (PM), intermediate (IM), normal (NM), and ultrarapid (UM) metabolizers. A total of 264 women met inclusion/exclusion criteria (99 cases and 165 controls). Multivariate regression analyses of metabolizer status and AS were adjusted for …

Derebail, David L. Feldman, Gia J. Oh, John W. Sleasman, Kristina A. Bryant, Improving Vaccination In Ckd Working Group

Department of Surgery Faculty Papers

People with chronic kidney disease (CKD) are particularly vulnerable to vaccine-preventable infections. Therefore, the National Kidney Foundation organized a multidisciplinary working group, including people with CKD and family care partners, to develop recommendations to improve vaccination rates, vaccination effectiveness, and health care for the CKD population. A modified Delphi process was used to achieve consensus on the recommendations. Recommendations on vaccination in CKD patients were organized into these categories: (1) patient preferences; (2) assessing the vaccination status of patients with CKD; (3) assessing vaccine response in patients with CKD; (4) vaccination of immunocompromised patients; (5) vaccination in posttransplant patients; (6) …

Determinants Of Agroecological Practices Adoption In Mango-Based Farming Systems: Evidence From Southern Ethiopia, Fasikaw Belay Mihretu, Melkamu Alemayehu, Mengistie Mossie, Yayeh Bitew, Tadele Tefera

All Peer-Reviewed Publications

Agroecological practices are a promising strategy for improving the productivity of mango-based farming systems sustainably. However, their adoptions among farmers in Ethiopia remain low and inconsistent. Despite their potential benefits, little is known about the extent of adoption, the interdependent nature of these practices, and the determinants associated with the farmers' decisions to adopt multiple agroecological practices. Hence, this investigation explores the determinants associated with the adoption of agroecological practices in mango-based farming systems in southern Ethiopia. The study employed a mixed-methods design using 395 randomly selected households. The multivariate probit and Poisson regression models were used for data analysis. …

Hybrid Deep Learning For Anti-Money Laundering: Unsupervised Detection Of Emerging Schemes Via Feature Fusion And Explainable Artificial Intelligence, Cosmas Ochieng Kungu, Kennedy Senagi, Evans Omondi

All Peer-Reviewed Publications

Traditional rule-based anti-money laundering (AML) transaction monitoring systems suffer from high false-positive rates and rigidity in detecting complex emerging risk. This limitation has prompted changes to the Financial Action Task Force (FATF) recommendation 16, mandating the use of advanced systems for detecting money laundering schemes in cross-border payments. This study developed a hybrid framework integrating VAE-learned behavioural latent factors, GNN-captured relational network signals, and rule-based heuristics for enhanced anomaly detection. The model was evaluated on 54,258 real-world cross-border transaction records from an East African commercial bank. The One-Class SVM, optimised via a rigorous grid search proved superior compared to Isolation …

Adapting Lessons From The Indian Subcontinent To Accelerate Elimination Of Visceral Leishmaniasis As A Public Health Problem In East Africa, Eva Iniguez, Daniel Masiga, Caryn Bern, Sridhar Srikantiah

All Peer-Reviewed Publications

This viewpoint draws lessons from the elimination of visceral leishmaniasis (VL) as a public health problem in the Southeast Asia region (SEAR) to inform efforts in East Africa (EA), now the global epicenter of Leishmania donovani transmission. VL is fatal and there is no licensed vaccine. Success in India relied on robust surveillance, rapid diagnosis, single-dose treatment, vector control, and multi-partner coordination. EA faces additional challenges than SEAR with multiple sand fly vectors, sensitive diagnostics and longer treatment regimens, high population mobility, and gaps in ecological and epidemiological knowledge. We highlight how strategies from South Asia could be adapted while …

From Relic To Relevance, The Resurgence Of Tariffs, Reuven S. Avi-Yonah, Doron Narotzki, Tamir Shanan

UC Law Journal

Modern legal scholarship has largely relegated tariffs to economic analysis, overlooking their legal and policy significance. This Article challenges that view by examining tariffs as a potential pillar of fiscal policy, exploring their viability as a revenue source alongside or in place of traditional income and corporate taxation. While historically central to U.S. government funding, tariffs’ importance diminished with the rise of income taxation and trade liberalization. However, their recent resurgence as a tool for trade protection raises broader questions about their role in national economic strategy.

This Article critically assesses the feasibility of a tariff-based tax system, drawing on …

The Gospel Of Glamour: A Christian Woman's Style Blueprint, Osaromwenyeke Osemwota

Theses

The Gospel of Glamour: The Christian Woman’s Style Blueprint was a luxury-branded, sustainability-focused, faith-based style guide that addressed a gap in fashion, theology, and sustainability scholarship. Existing literature had either systematized fashion, explored the spiritual significance of dress, or examined sustainable and luxury practices—but none had integrated these dimensions into a prescriptive, actionable guide for Christian women. Drawing on Scripture as the foundational authority, including passages from Genesis, Exodus, Psalms, and Proverbs, the guide framed clothing as both practical provision and visible expression of covenantal identity. The style guide synthesized secular fashion methodology, modest-fashion scholarship, and sustainable luxury principles to …

Artemisia Gentileschi's Judith And Her Maidservant Serves As A Message Of Hope, Holly Kyseth

Theses

This thesis argues that through iconography and specific artistic techniques, Artemisia Gentileschi’s Judith and Her Maidservant utilizes the biblical story of Judith and Holofernes to relay a distinctly female-centered narrative, reflective of the ideals of her seventeenth century Italian community. This piece stands apart from other representations of this narrative in that Judith was commonly shown as either dainty yet violent in the act of decapitating Holofernes, or as a saintly victor proudly displaying his head to her people. With Judith and Her Maidservant, Artemisia displays an obvious sororal alliance between Judith and her servant Abra, while cleverly implementing Caravaggesque …
