Motivating Physical Activity With Fitness Tracking And The Interpersonal Context, Sapphire H. Lin, Sonny Rosenthal, Rich Ling

Research Collection College of Integrative Studies

Many societies have aging populations. Getting older people to exercise can help them achieve a higher quality of life. Fitness tracking and social support can buttress that goal. This study tested the effects of fitness tracking and spousal influence on the physical activity of older adults. In a 2 (blinded vs. feedback) × 2 (individual vs. dyad) between-group experiment, 240 participants received a fitness tracker with a visible or blinded display. They participated in the three-month experiment either individually or with their spouses. Participants who received feedback met daily step counts of 7500 and 10,000 more frequently than those without …

Performance Of Artificial Neural Network Compared To Multi-Linear Regression In Prediction Of Countermovement Jump Height, Amirhossein Emamian, Alireza Hashemi Oskouei, Kristof Kipp, Rasoul Azreh

Exercise Science Faculty Research and Publications

Previous research has used primarily linear regression models to predict jump height and establish contributors of performance. The purpose of this study was to compare the performance of artificial neural network (ANN) and multi-linear regression (MLR) in prediction of countermovement jump (CMJ) height and investigating the contribution of kinematic variables to CMJ performance. Thirty-four healthy young male athletes performed a total of 204 CMJ while eight kinematic variables (the hip, knee, and ankle angles at the begging of the concentric phase of CMJ, the hip and knee take-off angles, and the shoulder, hip, and knee maximum angular velocities) were used …

Subsyndromes And Symptom Clusters: Multilevel Factor Analysis Of Behavioral And Psychological Symptoms Of Dementia With Intensive Longitudinal Data, Carolyn E Z Pickering, Vicki Winstead, Mustafa Yildiz, Danny Wang, Maria Yefimova, Andrew M Pickering

Faculty, Staff and Student Publications

Introduction: Behavioral and psychological symptoms in dementia (BPSD) are dynamic phenomena with a high amount of intraindividual variability. We applied a multilevel framework to identify subsyndromes (between-person factors) that represent clinically relevant profiles of BPSD and identify symptom clusters (within-person factors) that represent contextually driven daily symptom experiences.

Methods: This study used an intensive longitudinal design in which 68 co-residing family caregivers to persons living with dementia were recruited to proxy report on their care recipient's daily symptom experiences of 23 different BPSD for eight consecutive days (n = 443 diaries). A multilevel exploratory/confirmatory factor analysis was used to account …

Vessel-Targeted Compensation Of Deformable Motion In Interventional Cone-Beam Ct, Alexander Lu, Heyuan Huang, Yicheng Hu, Wojciech Zbijewski, Mathias Unberath, Jeffrey H Siewerdsen, Clifford R Weiss, Alejandro Sisniega

Faculty, Staff and Student Publications

The present standard of care for unresectable liver cancer is transarterial chemoembolization (TACE), which involves using chemotherapeutic particles to selectively embolize the arteries supplying hepatic tumors. Accurate volumetric identification of intricate fine vascularity is crucial for selective embolization. Three-dimensional imaging, particularly cone-beam CT (CBCT), aids in visualization and targeting of small vessels in such highly variable anatomy, but long image acquisition time results in intra-scan patient motion, which distorts vascular structures and tissue boundaries. To improve clarity of vascular anatomy and intra-procedural utility, this work proposes a targeted motion estimation and compensation framework that removes the need for any prior …

Hardware Control Unit For Trusted Program Verification System, Jake Owen Alt

Master's Theses

Trust in the underlying hardware is the foundational step towards trusting the correctness and integrity of a software application. However, verifying that today's extremely complex processors work exactly as intended has not been feasible, as evidenced by several recent hardware bugs. Trustworthy, formally verified processors currently forego intricate performance enhancements such as out-of-order execution, hampering them substantially versus their less secure counterparts.

The Containment Architecture with Verified Output (CAVO) system solves this problem by isolating the host system and requiring the result of each instruction to be validated by a small, trusted hardware module called the Sentry. Any transmissions to …

Towards An Extended Resource Theory Of Marital Power: Parental Education And Household Decision-Making In Rural China, Cheng Cheng, Yu Xie

Research Collection School of Social Sciences

Existing literature on the resource theory of marital power has focused on the relative resources of spouses and overlooked the resource contributions of spouses’ extended families. We propose an extended resource theory that considers how the comparative resources of a couple’s natal families are directly associated with marital power, net of the comparative resources of the couple. Using data from the China Panel Family Studies, we examine how the relative education of a couple’s respective parents affects the wife’s decision-making power, net of the relative education of the couple. Results suggest that the higher the wife’s parental education relative to …

Does Relationship Conflict Reduce Novel Idea Communication Through Perceived Leader Openness? Power Distance Orientation As A Moderator, Ming-Hong Tsai

Research Collection School of Social Sciences

Purpose: This paper aims to investigate why followers have low perceptions of leader openness and thus feel reluctant to communicate novel ideas by examining leader–follower relationship conflict (i.e. interpersonal incompatibility) and a follower’s power distance orientation (i.e. an acceptance of uneven power distribution in organizations) as antecedents. Design/methodology/approach: The research administrators conducted a three-wave work behavior survey in Study 1, a laboratory experiment in Study 2, and an online experiment in Study 3. Findings: The results demonstrated that leader–follower relationship conflict reduced followers’ perceptions of leader openness. However, the negative impact of relationship conflict became non-significant when followers have high …

Registered Replication Report: A Large Multilab Cross-Cultural Conceptual Replication Of Turri Et Al. (2015), Braeden Hall, Kathleen Schmidt, Jordan Wagge, Savannah C. Lewis, Sophia C. Weissgerber, Felix Kiunke, ..., Andree Hartanto

Research Collection School of Social Sciences

According to the justified true belief (JTB) account of knowledge, people can truly know something only if they have a belief that is both justified and true (i.e., knowledge is JTB). This account was challenged by Gettier, who argued that JTB does not explain knowledge attributions in certain situations, later called “Gettier-type cases,” wherein protagonists are justified in believing something to be true, but their belief was correct only because of luck. Laypeople may not attribute knowledge to protagonists with justified but only luckily true beliefs. Although some research has found evidence for these so-called Gettier intuitions, Turri et al. …

Deliberately Making And Correcting Errors In Mathematical Problem-Solving Practice Improves Procedural Transfer To More Complex Problems, Janson Boon Khang Yap, Sarah Shi Hui Wong

Research Collection School of Social Sciences

How can students effectively learn and transfer mathematical procedures to solve new problems? Here, we tested the effects of deliberately committing and correcting errors during mathematical problem-solving practice on transfer of the learned procedures. In two experiments, university students were instructed on mathematical algorithms (synthetic division and matrix multiplication) and solved practice problems during open-book study. Learners were then tested on flexibly adapting the algorithms to solve novel problems that were structurally more complex or embedded in “real-life” scenarios (i.e., mathematical word problems). Deliberately committing and correcting procedural errors during problem-solving practice yielded better transfer than errorless repeated practice (Experiment …

Regulating Crypto Intermediaries, Eric D. Chason

Faculty Publications

Early 2024 produced a dramatic rebound in cryptocurrency markets as Bitcoin hit an all-time high price in March 2024. This surge was fueled in large part by judicial and regulatory action. After years of denials and a high-profile defeat in court, the U.S. Securities and Exchange Commission (SEC) finally approved the first exchange-traded funds (ETFs) for Bitcoin in January 2024. Many believe that these approvals will lead to a greater shift of investment funds into crypto. Crypto regulation is not, however, ready for this shift. While ETFs have clear treatment under current law, other institutions lack the same clarity or …

Extraterritoriality's Empire: How Self-Determination Limits Extraterritorial Lawmaking, Evan J. Criddle

Faculty Publications

In recent years, a growing number of countries have courted controversy by regulating activities outside their borders. They have used extraterritorial lawmaking to cultivate competitive global markets, strengthen or weaken data privacy, combat foreign terrorism and military aggression, promote human rights abroad, and suppress political dissent at home. This Article explores whether extraterritorial lawmaking can be reconciled with the right to self-determination under international law. I argue that the right to self-determination entitles each national polity to determine the laws and institutions by which it is governed within its territory. Extraterritorial lawmaking violates the right to self-determination when it subjects …

Emergency Powers For Good, Elena Chachko, Katerina Linos

William & Mary Law Review

Emergency powers are widely, and justly, criticized as threats to the rule of law. In the United States, forty-three declared emergencies give the executive vast authority to exercise power unencumbered by standard legal and procedural requirements. A long tradition of executive use of emergency powers to erode civil liberties amplifies fears of executive overreach.

Yet this, we argue, is only part of the picture. We examine how emergency powers can be used for good. We argue that under certain limited conditions, political actors can legitimately invoke emergency powers to transform public policy. In addition to widely accepted requirements of crisis …

Sackett V. Epa And The Future Of Wetland Protections, Dulaney Marsh

William & Mary Law Review

This Note will analyze prior CWA [Clean Water Act] jurisprudence to formulate a test that remains steadfast to Congress’s purpose in originally including “adjacent” wetlands and acknowledges the scientific understanding of wetlands’ relation to and impact on waters. Part I will provide an overview of the CWA legislation and its application in courts. Part II will specifically analyze the Sackett v. EPA decision in order to find a balance between the “significant nexus” and “continuous surface connection” tests. Part III will address criticisms surrounding the overreach of the CWA. Part IV will conversely address criticism concerning the Court’s decision to …

A Content Analysis Of Counseling Psychology Literature: Resilience Against Oppression Among People Of Color, David C. Stanley Jr., Rawan H. Atari-Khan

Psychology Faculty Research and Publications

The researchers analyzed articles from two flagship counseling psychology journals (i.e., Journal of Counseling Psychology and The Counseling Psychologist) to examine current understandings of resilience. There were 54 articles included in the final analysis that spanned the years 1997–2022. The researchers conducted a content analysis to identify, analyze, and report patterns across counseling psychology journals with regard to how resilience has been defined, the racial/ethnic groups that were of focus, and the forms of oppression that were studied or addressed. Five themes were generated that are a direct representation of the topics within previous literature on resilience in the field …

Evaluating The Efficacy Of And Preference For Interactive Computer Training With Student-Generated Examples, Sylvia C. Aquino, Stephanie Hood, Tara A. Fahmie, Richard Tanis

Psychology Faculty Research and Publications

Designing effective and preferred teaching practices for undergraduate students are common goals in behavior analytic training programs. A preliminary study by Nava et al. (2019) showed that undergraduate students generally rated peer-generated examples of the principles of behavior analysis as more preferred, relatable, and culturally responsive than traditional textbook examples. However, peer-generated examples did not result in any improvement in performance on concept knowledge assessments. The current study extended the study by Nava et al. by embedding peer-generated examples within interactive computer training (ICT) to provide opportunities for active responding, prompt fading, automated feedback, and practice with examples and nonexamples. …

Oxyfluorfen Use In Combination With Clomazone Or Quinclorac, Jason K. Norsworthy, Casey H. Arnold, Thomas R. Butts, Chad W. Shelton

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Oxyfluorfen is a herbicide that inhibits protoporphyrinogen IX oxidase and has shown significant potential in its ability to control barnyardgrass. Oxyfluorfen is categorized as a Group 14 herbicide by the Herbicide Resistance Action Committee (HRAC)/Weed Science Society of America (WSSA). Despite its current lack of labeling for use on rice in the mid-southern United States due to its potential to cause crop injury, the introduction of a trait in rice that confers resistance to oxyfluorfen could provide producers with an effective alternative site of action for weed control. Field experiments were conducted during the 2021 and 2022 growing seasons near …

Clomazone And Oxyfluorfen Combinations In A Flooded Rice System, Jason K. Norsworthy, Casey H. Arnold, Thomas R. Butts, Trenton L. Roberts, Chad W. Shelton

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Rice producers battle herbicide-resistant weeds worldwide while producing rice for ≥50% of the world’s population. Oxyfluorfen can provide rice producers with an alternative site of action for barnyardgrass control, as there are no documented cases of grass weeds being resistant to the herbicide in the mid-southern United States. Oxyfluorfen is anticipated to be labeled in the Roxy Rice Production System and may be sold as a clomazone/oxyfluorfen premixture; hence, experiments were conducted in 2021 and 2022 to evaluate preemergence-applied clomazone/oxyfluorfen ratios compared to clomazone alone on silt loam and clay soils. All ratios of the herbicides caused less than 7% …

Realtime And Noninvasive Assessment Of Endotracheal Tube Displacement Using Near-Infrared And Visible Cameras, Tongtong Lu, Pawjai Khampang, Ahmed Beydoun, Rebecca Rodhe, Wenzhou Hong, Joseph E. Kerschner, Bing Yu

Biomedical Engineering Faculty Research and Publications

Endotracheal tube (ETT) intubation is a medical procedure routinely used for achieving mechanical ventilation in critically ill patients. Appropriate ETT placement is crucial as undetected tube migration may cause multiple complications or even fatalities. Therefore, prompt detection of unplanned movement of the ETT and immediate action to restore proper placement are essential to ensure patient safety. Despite this necessity, there is not a widely adopted tool for real-time assessment of ETT displacement. We have developed a device, a dual-camera endotracheal tube or DC-ETT, to address this unmet clinical need. This device uses a near-infrared (NIR) LED and a side-firing optical …

Morphology Of The Normative Human Cone Photoreceptor Mosaic And A Publicly Available Adaptive Optics Montage Repository, Robert F. Cooper, Snega Kalaparambath, Geoffrey K. Aguirre, Jessica I. W. Morgan

Biomedical Engineering Faculty Research and Publications

Adaptive optics ophthalmoscopy has enabled visualization of the in vivo human photoreceptor mosaic in health, disease and its treatment. Despite this, the clinical utility of the imaging technology has been limited by a lack of automated analysis techniques capable of accurately quantifying photoreceptor structure and a lack of an available normative image database. Here, we present a fully automated algorithm for estimating cone spacing and density over a complete adaptive optics montage along with a database of normative images and cone densities. We imaged the cone mosaics surrounding the fovea and along the horizontal and vertical meridians of fifty normal-sighted …

Talar And Calcaneal Coordinate Axes Definitions Across Foot Pathologies, Kassidy Knutson, Erika P. Muhlrad, Andrew C. Peterson, Thomas Leonard, Abigail M. Anderson, Katelyn C. Aragon, Zachary J. Eatough, Bruce A. Macwilliams, Karen M. Kruger, Amy L. Lenz

Biomedical Engineering Faculty Research and Publications

The understanding of foot and ankle biomechanics is improving as new technology provides more detailed information about the motion of foot and ankle bones with biplane fluoroscopy, as well as the ability to analyze the hindfoot under weightbearing conditions with weightbearing computed tomography. Three-dimensional anatomical coordinate systems are necessary to describe the 3D alignment and kinematics of the foot and ankle. The lack of standard coordinate systems across research study sites can significantly alter experimental data analyses used for pre-surgical evaluation and post-operative outcome assessments. Clinical treatment paradigms are changing based on the expanding knowledge of complex pes planovalgus morphologies …

Lumbar Spine Orientation Affects Compressive Fracture Outcome, Rachel Cutlan, Muhammaed Khokhar, Nader Shammout, Alok Shah, Lance Frazer, Narayan Yoganandan, Barry S. Shender, James Sheehy, Glenn Paskoff, Daniel Nicolella, Timothy B. Bentley, Saman Shabani, Brian D. Stemper

Biomedical Engineering Faculty Research and Publications

Purpose

Understanding how spinal orientation affects injury outcome is essential to understand lumbar injury biomechanics associated with high-rate vertical loading.

Methods

Whole-column human lumbar spines (T12–L5) were dynamically loaded using a drop tower to simulate peak axial forces associated with high-speed aircraft ejections and helicopter crashes. Spines were allowed to maintain natural lordotic curvature for loading, resulting in a range of orientations. Pre-test X-rays were used to quantify specimen orientation at the time of loading. Primary fracture types were identified (wedge, n = 6; burst, n = 4; hyperextension, n = 4) and compared for loading parameters and lumbar orientation. …

The Framework Is The Message: Legal And Ethical Implications Of Chatgpt, Amanda Turnbull

Canadian Journal of Law and Technology

The rapid rise of generative AI represents a palpable paradigm shift: models like GPT-3 (and its subsequent iterations), DALL-E, and AlphaCode are becoming foundation models for many other AI-based applications. Foundation models may be used for many different tasks with minimal modification and are positioned to replace task-specific models of AI. This holds tremendous promise in society such as advancing scientific research, rethinking education and training, and creating new types of art and expression. At the same time, however, generative AI has its dark side such as accuracy risk, the threat of large-scale unemployment, potential security vulnerabilities, and AI misbehaviour …

Theistic Illiberal Constitutionalism: A Review Of Adrian Vermeule’S Common Good Constitutionalism, Kyron J. Huigens

Articles

Adrian Vermeule’s Common Good Constitutionalism drew a remarkable amount of attention from constitutional law scholars when it was published in 2020. About eighteen months later, Vermeule published a piece complaining that the critics had missed the point, that they had ignored the natural law jurisprudence that grounds the work. He was correct. This Review addresses Vermeule’s natural law jurisprudence, emphasizing the fact that it is a religious natural law jurisprudence. His arguments are in the tradition of ScholasticismAristotelian logic incorporated into Christian theology by St. Thomas Aquinas. Scholasticism is a remarkably weak foundation for constitutional jurisprudence. It is a vast …

Multi-Generation Queer Families: Foregrounding The Lgbtqia+ Children Of Lgbtqia+ People, Bella Mancini Pori, Edward Stein

Articles

In the last several years, state legislatures have passed a disturbing array of anti-queer laws that target queer (especially trans) children. The basic fear animating these laws is that exposure to LGBTQ people or LGBTQ supportive ideas will somehow turn straight children queer. LGBTQ activists have responded to the concern that exposure to queer people or ideas will make children queer by arguing that sexual orientations are innate or immutable. This immutability argument is problematic, first, because it avoids confronting the normative judgment at the heart of the fear of a queer child by failing to say that there is …
