Comparing The Sensitivity And Specificity Of Novel Motor Assessments For Traumatic Brain Injury, Paula K. Johnson, Ariana M. Hedges-Muncy, Erin D. Bigler, Lorie Richards, Steven Knight Charles

Faculty Publications

Background: Portable technology that records movements with high accuracy provides potential for sensitive clinical movement tests for individuals who experienced a traumatic brain injury (TBI). Objective: (1)To present impairments assessed using markerless motion capture (MMC) and (2) to compare the sensitivity and specificity of the MMCmediated tests to each other and to common clinical tests. Design: Screening study, using as criterion standard the ability to classify participant with TBI versus control participant. Setting: Research laboratory. Participants: The study included 30 individuals with TBI and 101 control participants. Entry criteria included most recent head injury < 5 years old, no history of movement issues prior to injury, no movement-affecting medications, and sufficient cognitive ability to follow instructions. Interventions: Not applicable. Main Outcome Measures: Performance on MMC-mediated tests and existing clinical analogs. MMC-mediated tests included finger oscillation, simple reaction time, and visually guided movement tasks. For comparison, participants also completed the following clinical tests: Halstead–Reitan finger tapping, simple reaction time test, and Beery Visuomotor Integration test. Impairments were identified as test scores of participants with TBI that fell outside of the 95% interval of control participants’ test scores. Random forest analysis was used to calculate the sensitivity and specificity of MMC and clinical tests according to their ability to correctly classify participants with TBI and control participants. Results: MMC-mediated tests revealed impairments in more participants with TBI than clinical tests in all three TBI groups (mild, repeated, and moderate to severe). Similarly, MMC-mediated tests revealed a higher percentage of scores as impairments than clinical tests in all three groups with TBI. Furthermore, MMC-mediated tests proved more sensitive and more specific than clinical tests (70% versus 50% and 98% versus 93%, respectively). Conclusion: MMC-mediated tests are sensitive and specific (compared to traditional clinical tests) and have potential to fill a gap in clinical care of TBI.

Dictyostelids: The Second Major Group Of Slime Molds, P. Liu, Z.J. Zhang, J.H. Ge, Y. Zou, Z. Li, S. Li, Y. Li, S.L. Stephenson

Biological Sciences Faculty Publications and Presentations

The dictyostelids (also called cellular slime molds or social amoebae) are among the more abundant and widespread groups of microorganisms in terrestrial ecosystems. Despite this fact, they are totally unknown to most people, who sometimes confuse the dictyostelids with myxomycetes (or plasmodial slime molds). The first dictyostelid (Dictyostelium mucoroides) was described by the German Oskar Brefeld in 1869. More than 180 species are now known, and these organisms have been recorded from the high arctic to the subantarctic. The primary microhabitat for dictyostelids is the soil/humus layer on a forest floor, but they also occur in a number of other …

The Impact Of Covid-19 Pandemic On Economic Convergence Between Developed And Developing Nations, Lucile Sabas, Williams Kwasi Peprah [email protected], Carmelita Troy, Quentin Sahly

Faculty Publications

This study investigates convergence between developed and developing countries’ GDP during the pre-COVID-19 era (1960-2019) and post-COVID-19 era (2020-2023) using World Bank data and the Augmented Dickey-Fuller (ADF) test. For the pre-COVID period, results show no significant convergence, with an ADF statistic of −1.78 and a P = 0.39, likely due to disparities in industrialization and governance. Similarly, post-COVID results (ADF statistic −1.2, P = 0.67) also suggest no convergence, possibly exacerbated by pandemic-related challenges. The study highlights that structural barriers and the pandemic have hindered economic convergence.

Actuator Disk Model For Aeropropulsive Coupling Effects In Vortex Particle Method, Eduardo Alvarez, Vineet Ahuja, Vinod Lakshminarayan, Aaron Perry, Ryan Anderson, Andrew Ning

Faculty Publications

Blown lift and distributed electric propulsion aircraft pose strong aeropropulsive coupling effects that cannot be ignored during the early stages of design. In this study, we develop an advanced actuator disk model (ADM) for aeropropulsive coupling effects of ducted fans with the vortex particle method (VPM). The advanced ADM consists of (1) an actuator disk at the rotor plane, (2) a surface vortex sheet modeling the mixing and convection of blade tip vorticity along walls, and (3) a powered wake at the exhaust. With these three components, a propulsion jet with an arbitrary velocity profile is formed and interactions with …

Designing For Relational Ethics In Online And Blended Learning: Levinas, Buber, And Teaching Interfaith Ethics, Michael Hubbard Mackay, Jason K. Mcdonald, Andrew C. Reed

Faculty Publications

Online and blended learning (OBL) overemphasize the process of creating artifacts, producing strategies, or otherwise utilizing a “making” orientation in education. As an alternative to this making-orientation, we offer a model for relational course design founded in the philosophies of Emmanuel Levinas and Martin Buber. We examine an OBL course design focused on interfaith leadership and ethics that lends itself to the need for relational pedagogy. The focus on asymmetrical and symmetrical relationships that separate Levinas and Buber’s philosophies enable rich ways of designing relational pedagogies and for resisting the making orientation. By focusing on human relationships, we demonstrate design …

Creating And Implementing An Inclusive Metadata Policy, Nicole Lewis, Jeremy Myntti

Faculty Publications

The BYU Library developed an Inclusive Metadata Policy for metadata creators to use when creating and remediating descriptions to be more inclusive. Accompanying the policy is a companion document with recommendations and examples, including links to many external resources. In addition to working with stakeholders in the library to develop the policy, we consulted with the University’s Office of Belonging. This presentation will describe the process we used to create the library policy and recommendations document and share information about how the policy has been implemented.

Rice Plants Response To Modulation Of The Erecta Signaling, Yasmin Vasques Berchembrock, Flavia Barbos Silva Botelho, Bhuvan Pathak, Shan Zhao, Vibha Srivastava

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

The ERECTA family of receptors (ERfs), encoding leucine-rich repeat receptor-like kinases (LRR-RLKs), can regulate multiple aspects of plant development and abiotic stress responses. The rice (Oryza sativa) genome contains three ERfs, namely ERECTA 1 (OsER1), ERECTA 2 (OsER2), and ERECTA-LIKE (OsERL). However, there is limited information currently available on their expression pattern during the plant developmental stages. The expression pattern of OsERfs genes at reproductive stages from the booting (R2) to milk (R6) stage in Nipponbare cultivar and the transgenic plants expressing a truncated Arabidopsis ERECTA (ER) lacking the kinase domain (triangle Kinase) were studied. The triangle Kinase functions as …

Fear Of Balancing, William Baude

Public Law and Legal Theory Working Papers

As a new Supreme Court majority settles into a new era of constitutional adjudication, the Justices will confront important methodological questions. How are they to go about interpreting the Constitution? In the Second Amendment case of United States v. Rahimi,1 many of the Justices wrote separately to debate broader methodological questions about constitutional interpretation. They expressed a shared desire to turn away from judicial “balancing” of interests in adjudicating constitutional rights in favor of founding-era understandings. That is a healthy instinct, but founding-era understandings may in truth lead to balancing, so maintaining an originalist approach and an opposition to balancing …

Do Constitutional Unamendability Rules Make A Difference?, Adam Chilton, Mila Vertseeg

Public Law and Legal Theory Working Papers

Leaders often try to amend constitutions to remove checks on their powers. To help protect against such democratic erosion, constitutional drafters and jurists sometimes restrict constitutional amendments by: (1) specifying in the constitutional text that certain clauses or principles can never be changed (“Eternity Clauses”); (2) granting apex courts the power to review the procedural validity of amendment processes (“Amendment Review”); or (3) developing judicial doctrines that block amendments that change the constitution’s nature (“Unamendability Doctrines”). But are unamendability rules actually associated with differences in countries’ levels of democracy? We argue that Eternity Clauses are likely to emerge in conditions …

Remedies In The Officer Removal Cases, Samuel L. Bray

Public Law and Legal Theory Working Papers

When an officer challenges her removal by the president, what relief is available? This Article shows that the appropriate remedy will typically be a declaratory judgment. The interim relief question is harder. The suggestion here is that if an officer sues immediately to challenge her removal, there should be a presumption that the federal courts will prevent her removal during the pendency of the litigation. Otherwise, the presumption should be against interim relief. This approach is grounded in the principles of equity, and it prevents “flipping” back and forth in who occupies the office during the litigation.

Stubhub For Courts? Technology, Markets, And New Solutions To Court Congestion, Ronen Avraham, William H. J. Hubbard

Public Law and Legal Theory Working Papers

Rescheduling of court hearings is ubiquitous but virtually ignored by academic scholarship. This is so, despite its contributions to court congestion, a perennial problem for courts that has been the subject of repeated, and repeatedly unsuccessful, efforts at reform. In this Article, we aim to show that rescheduling merits scholarly attention, and by diagnosing why and how it contributes to court congestion and delay, we both explain why most efforts at reducing delay fail and identify new possibilities for speeding up dockets. We draw inspiration from online platforms such as StubHub and SpareFare, technologies that have facilitated rescheduling through easy-to-use …

Comparative Effectiveness Of Conservative Versus Early Surgical Treatments On Wound Healing Outcomes Of Diabetic Foot Ulcers: A Literature Review, Paul Tran, Yasim Zafar, Andrea Piña, Stephanie N. Campbell

School of Podiatric Medicine Publications

Diabetic foot ulcers (DFUs) are a severe complication of diabetes mellitus and the leading cause of lower extremity amputations worldwide. Peripheral neuropathy and peripheral arterial disease secondary to complications of diabetes mellitus may result in ulcers going unnoticed, increasing the risk of severe osteomyelitis, necrotizing infection, hospitalization, amputation, and sepsis. While conservative management of DFUs remains the first-line approach—emphasizing wound care, infection control, glycemic management, and offloading—there is growing debate about whether delaying simple surgical interventions worsens long-term outcomes. Surgeries such as tenotomy, digital amputation, and tendo-Achilles lengthening are minimally invasive options that can correct deformities, prevent recurrence, and promote …

Turbo Fladry Fencing To Mitigate Short-Term Agricultural Damage Caused By Wild Pigs, Michael P. Glow, Jesse A. Tussing, Johnathan G. Walls, Robert B. Hyle, Joseph M. Halseth, Nathan P. Snow, Kurt C. Vercauteren

Human–Wildlife Interactions

Wild pigs (Sus scrofa) are a destructive invasive species that damage agricultural crops in many regions of the world. Lethal techniques to reduce populations are most often used to mitigate damage, but additional techniques are also needed in conjunction with lethal tools to protect resources in some settings (e.g., where lethal control is not practical or possible to achieve population elimination). While additional tools such as deterrents or temporary fencing may provide short-term relief, few effective options are currently available because habituation by wild pigs often reduces long-term effectiveness. Turbo fladry, a type of electric fence, is an …

Heart Rate Variability And Personality Traits As Predictors Of Arabic Language Proficiency And Gains During Study Abroad In Jordan, Kirk Belnap, Dan P. Dewey, Patrick Steffan, Annika Barrick Bickmore, Khalil Yousef

Faculty Publications

High stress predicts mood and anxiety disorders and can necessitate clinical intervention (Steffen et al., 2014). Language learners often experience high stress during intensive study abroad (SA) programs (Dewey et al., 2018), which can hinder communication (Buttaro, 2004; Peck, 1974). Acculturative stress is common among second language (L2) speakers and can coincide with stress related to the inability to communicate one’s thoughts and ideas (Savicki, 2010), further complicating communication. Therefore, reducing stress in immersive settings can be crucial due to the link between stress, L2 use, and psychological wellbeing (Dewaele & Dewaele, 2021). We report an exploratory investigation of the …

Origami Folding Pattern Development For Gossamer 18 Structures, Larry L. Howell, Ivy Running, Carolina Wright, Robert J. Lang, Spencer Magleby

Faculty Publications

Gossamer structures for satellites are large, thin deployable structures that are attractive for space applications because they can be stowed compactly for transportation and deployed to have large functional surface areas. Reflectarray antennas, in particular, are candidates for gossamer structures because they can be realized on thin membranes. However, the efficiency of reflectarray antennas decreases with any deviations from a flat plane, including those induced by plastically deformed creases. Rolling membranes can prevent some plastic deformation, but requires relative slipping between layers that are rolled together. In this work, we describe, analyze, and demonstrate two rolled configurations for deployable gossamer …

Internally Stowed, Radially Deployed Radiator Panels For Passive Cubesat Thermal Control, Josh R. Cannon, Kyle N. Havey, Noah S. Housley, Rydge B. Mulford, Brian D. Iverson

Faculty Publications

CubeSats experience significant thermal loads due to solar irradiation and the dissipation from electrical components. The high heat dissipation per unit volume can lead to mission failure if not properly managed. Deployable radiators that are externally stowed and passively actuated in response to changes in CubeSat temperature have been explored as a viable solution. This work describes a radially deployed fin array that is stowed within the CubeSat body when the required heat dissipation is low and passively deploys when the required heat dissipation is high. Internal stowage improves thermal transport to the deployable fins and minimizes heat loss when …

Drop Dynamics During Condensation On Superhydrophobic Surfaces In Vapor Shear Flow, Shaur Humayun, R. Daniel Maynes, Julie Crockett, Brian D. Iverson

Faculty Publications

Accurate models for predicting drop dynamics, such as maximum drop departure sizes, are crucial for estimating heat transfer rates during condensation on superhydrophobic (SH) surfaces. Previous studies have focused on examining the heat transfer rates for SH surfaces under the influence of gravity or vapor flowing over the surface. This study investigates the impact of surface solid fraction and texture scale on drop mobility in a condensing environment with a humid air flow. Experiments recorded condensation with varying surface feature sizes from micro- to nano scale under different flow rates. Video analysis detected the drop-size distribution and maximum drop departure …

Respiratory Monitoring With Textile Inductive Electrodes In Driving Applications: Effect Of Electrode's Positioning And Form Factor On Signal Quality, James Elber Duverger, Victor Bellemin, Geordi-Gabriel Renaud Dumoulin, Patricia Forcier, Justine Decaens, Ghyslain Gagnon, Alireza Saidi

Études primaires

This paper provides insights into where and how to integrate textile inductive electrodes into a car to record optimal-quality respiratory signals. Electrodes of various shapes and sizes were integrated into the seat belt and the seat back of a driving simulator car seat. The electrodes covered various parts of the body: upper back, middle back, lower back, chest, and waist. Three subjects completed driving circuits with their breathing signals being recorded. In general, signal quality while driving versus sitting still was similar, compared to a previous study of ours with no body movements. In terms of positioning, electrodes on seat …

Tackling Paradoxes And Double Binds For A Healthier Workplace: Insights From The Early Covid-19 Responses In Quebec And Ontario, Daniel Côté, Amelia León, Ai-Thuy Huynh, Jessica Dubé, Ellen Maceachen, Pamela Hopwood, Marie Laberge, Samantha Meyer, Meghan K. Crouch, Joyceline Amoako

Études primaires

The urgency of managing the COVID-19 health crisis in workplaces led to tensions, work overload, and confusion about preventive measures. This study presents a secondary analysis of qualitative data on paradoxes and double binds (PDBs) experienced by precarious essential workers in Canada who interacted with the public and their supervisors. Based on 13 interviews from a larger qualitative dataset, we examine how workers navigated public health recommendations and organisational demands during the pandemic. Findings reveal multiple organisational and managerial PDBs—both COVID-19-related and pre-existing—that contributed to psychological distress and compromised well-being. We argue that PDBs represent a significant occupational health hazard …

Do Urinary Metabolites Reflect Occupational Exposure To Organophosphate Flame Retardants? A Case Study In Electronic Waste Recycling Workers, Sabrina Gravel, Inna Tata Traore, Miriam Diamond, Liisa Jantunen, Joseph Zayed, France Labrèche, Marc-André Verner

Études primaires

Organophosphate esters (OPEs) are commonly used in electronic devices to meet safety standards, but electronicwaste recycling (e-recycling) workers may face significant exposure to those potentially hazardous compounds in their workplace. We examined the relationship between urinary OPE metabolites and their parent compounds in the air, in Canadian e-recycling facilities. We collected personal air samples and end-of-shift urine samples from workers at six e-recycling facilities. We employed linear and Tobit regression models to assess associations between air concentrations of triphenyl phosphate (TPhP) and three metabolites, of tris (2-chloroethyl) phosphate (TCEP) and two metabolites, of tris (2-chloroisopropyl) phosphate (TCPP) and two metabolites, …

Data were explored through inductive thematic analysis. The COREQ checklist was followed. Results: The analysis revealed five themes: adapting and self-managing in daily life, handling and carrying information, building trust and continuity, acting in a flexible and transparent dialogue and sharing the way forward. The participants described …

The Effect Of Deferring Feedback On Rule-Based And Information-Integration Category Learning, Charlotte E.R. Edmunds, Kathryn Carpenter, Andy J. Wills, Fraser Milton

School of Psychology

Previous work has shown that deferring feedback significantly impairs two-dimensional information-integration category learning, often thought to recruit an implicit learning system, but leaves intact unidimensional rule-based learning, commonly assumed to engage an explicit system. These results were taken to support the influential COmpetition between Verbal and Implicit Systems (COVIS) dual-process theory. This conclusion has subsequently been challenged by the finding that this dissociation disappears when the number of relevant dimensions is matched between tasks. However, as well as replacing a unidimensional rule-based task with a two-dimensional conjunction task, a different set of stimuli were used making it unclear which of …

School of Psychology

Cross-cultural studies are crucial for investigating the cultural variability and universality of cognitive developmental processes. However, cross-cultural assessment tools in cognition across languages and communities are limited. In this article, we describe a gaze-following task designed to measure basic social cognition across individuals, ages, and communities (the Task for Assessing iNdividual differences in Gaze understanding-Open-Cross-Cultural; TANGO-CC). The task was developed and psychometrically assessed in one cultural setting and, with input of local collaborators, adapted for cross-cultural data collection. Minimal language demands and the web-app implementation allow fast and easy contextual adaptations to each community. TANGO-CC captures individual- and community-level variation …

What Can Conjuring Tell Us About Cognition? The Future Of The Science Of Magic, Geoff G. Cole, Gustav Kuhn

School of Psychology

During the past 20 years a number of articles have appeared within a field that has become known as the “science of magic.” This subdiscipline of psychology posits that the ancient art of conjuring can be used to develop psychological theories and knowledge, and more than 150 peer-reviewed articles have now been published. In the current article, we critically evaluate what can be considered as the three central tenets of the discipline: that the methods used in magic can be incorporated within experimental research, that magicians have particular insight into human cognition and behavior, and that the deconstruction of magic …

Cross-Cultural Data On Romantic Love And Mate Preferences From 117,293 Participants Across 175 Countries, Marta Kowal, Piotr Sorokowski, Biljana Gjoneska, Katarzyna Pisanski, Gerit Pfuhl, Leonardo Aguilar, Steve M.J.

School of Psychology

Psychological studies on close relationships have often overlooked cultural diversity, dynamic processes, and potentially universal principles that shape intimate partnerships. To address the limited generalizability of previous research and advance our understanding of romantic love experiences, mate preferences, and physical attractiveness, we conducted a large-scale cross-cultural survey study on these topics. A total of 404 researchers collected data in 45 languages from April to August 2021, involving 117,293 participants from 175 countries. Aside from standard demographic questions, the survey included valuable information on variables relevant to romantic relationships: intimate, passionate, and committed love within romantic relationships, physical-attractiveness enhancing behaviors, gender …

Strabismus And Amblyopia Disrupt Spatial Perception But Not The Fidelity Of Cortical Maps In Human Primary Visual Cortex, D. Schluppeck, D. Arnoldussen, Z. Hussain, J. Besle, S. T. Francis, P. V. Mcgraw

School of Psychology

Amblyopia is a common disorder of spatial vision and is frequently associated with the presence of anisometropia, strabismus, or both, during visual development. For highly visible stimuli, subjects with strabismic amblyopia often report marked spatial distortions, but the neural basis of this supra-threshold deficit is not well understood. Here, we used a combination of behavioural measurements and visual field mapping with high spatial-resolution functional magnetic resonance imaging (fMRI) at 7 T to assess perceptual distortions in 12 participants with strabismic amblyopia and 9 control subjects. We measured both behavioural and cortical visual field maps monocularly through each eye. Although amblyopic …

More Than Just A Magic Trick? Exploring An Audience's Supernatural Attributions For Magicians' Performances, Paul J. Silvia, Sara J. Crasson, Gil Greengross, Gustav Kuhn

School of Psychology

Performing magicians have long believed that some audience members attribute their magical effects to supernatural methods—to their use of “real magic”. In two samples of adults (n = 412 and 292), we explored personality traits and broader beliefs that might predict supernatural attributions for performance magic. Supernatural attributions were uncommon—many respondents wholly rejected the possibility that magicians' magic was sometimes real—but nevertheless highly variable. In Study 1, a greater belief that magic tricks at least sometimes involve supernatural powers was associated with relatively higher extraversion, higher neuroticism, and lower openness to experience. In Study 2, random forests suggested that supernatural …

Clinical Decision Making And Risk Appraisal Using Electronic Risk Assessment Tools For Cancer Diagnosis: A Qualitative Study Of Gp Experiences, Alex Burns, Emily Fletcher, Elizabeth Shephard, Raff Calitri, Mark Tarrant, Adrian Mercer, William Hamilton, Sarah Dean

School of Psychology

Background: Electronic risk assessment tools (eRATs) are intended to improve early primary care cancer diagnosis. eRATs, which interrupt a consultation to suggest a possibility of a cancer diagnosis, could impact clinical appraisal and the experience of the consultation. This study explores this issue using data collected within the context of the Electronic RIsk-assessment for CAncer (ERICA) trial. Aim: To explore views and experiences of GPs who used the ERICA eRATs, how the tools impacted their perception of risk and diagnostic thinking, and how this was communicated to patients. Design & setting: Qualitative interviews with GPs from English general practices undertaking …
