Background: The importance of assessing family satisfaction in paediatric intensive care units (PICUs) is becoming increasingly recognised. The survey, EMpowerment of Parents in THe Intensive Care “EMPATHIC-30”, was designed to assess family satisfaction and has been translated and implemented in several countries but not yet in Japan. Objectives: The objective of this study was to translate, culturally adapt, and validate the EMPATHIC-30 questionnaire in Japanese and to identify potential factors for family-centred care satisfaction. Methods: We translated and adapted for patient-reported outcome measures via a 10-step process outlined by the Principles of Good Practice. Four paediatric PICUs in Japan participated …

Metal Contamination In Sediments Of An Estuary Impacted By Discharges Of Antifouling Waste (Yealm, Southwest England), Oliver Bradley, Gillian A. Glegg, Geoffrey E. Millward, Andrew Turner

School of Geography, Earth and Environmental Sciences

The Yealm is a small, protected estuary in southwest England. A paint-testing laboratory on the estuary operated from the 1920s until 2011 but sometime in 2015 or 2016, an unauthorised discharge of antifouling waste occurred. In this study, concentrations of metals and forms thereof associated with contemporary and historical antifouling formulations (As, Cu, Hg, Pb, Sn, Zn, organic Hg, organic Sn), along with other elements of geochemical or anthropogenic interest, were measured in fractionated (<180 μm) surface sediments at different distances from the discharge. Close to the discharge, concentrations of organic-Sn, representative of tributyltin, exceeded a level that requires material disposal in landfill; here and upestuary, concentrations of Cu and Hg exceeded respective predicted effect levels for estuarine sediments. Analysis of paint flakes isolated from sediments outside the laboratory revealed similar chemical signatures (high concentrations of Cu in most flakes and high levels of Hg and Sn in several cases), consistent with antifouling paint being the cause of contamination. Concentrations of Cu, Hg and organic Sn in sections of a dated core sampled close to the discharge exhibited enrichment since the opening of the laboratory nearly 100 years ago, with distinctive peaks for Hg and organic Sn coincident with periods shortly after these biocidal metals began to be phased out or restricted. These observations suggest that historical waste discharges may have been important and that any remediation measures will be challenging. The general observations might also be applicable to other facilities where contemporary and legacy antifouling waste is commonly discharged to sediments (e.g., boatyards).

Field Learning And Employability In Geography, Earth, And Environmental Sciences, Jacqueline Dohaney, Alison Stokes

School of Geography, Earth and Environmental Sciences

Society needs talented Geography, Earth and Environmental Sciences (GEES) graduates to help address global challenges, but the pathway to professional employment is seldom easy. After graduation, most GEES graduates enter professions requiring broad transferable skills and 'value-added' experiences to thrive in the modern workforce. GEES educators can therefore enhance employability by using field experiences to introduce and develop transferable skills valued by employers. Here, we define employability for our context, explore GEES graduate skills and describe the ways that communication, project management and personal and professional skills can be embedded in field experiences guided by the available literature. We identify …

Analytical Inconsistencies In The Measurement And Reporting Of Ip25, Ipso25 And Related Biomarkers For Paleo Sea Ice Reconstruction, Simon T. Belt, Lukas Smik

School of Geography, Earth and Environmental Sciences

IP₂₅ and related biomarkers are commonly used for Arctic and Antarctic sea ice reconstruction. With a growing number of laboratories performing their measurement, we reviewed many publications spanning the period 2007–2024 in order to assess analytical rigour. We found a number of common shortfalls in analytical protocols, or at least how they are reported, which may have important implications for future synthesis studies and meta-data analyses. Here, we outline some of these shortcomings and provide suggestions of how to improve both data acquisition and reporting.

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.

Cfl Learners’ Real-Time Processing Of Chinese Radicals: An Eye-Tracking Study, Yihsuan Wood, Jeffrey Jack Green, Ellen Knell, Yu Liu

Faculty Publications

This study used eye-tracking to investigate the real-time processing of phonetic and semantic radicals (components of Chinese characters that give clues to their pronunciation and meaning) by intermediate-level university Chinese foreign language (CFL) learners. Additionally, the study examined how knowledge and awareness of radicals affect real time character processing. Real-time radical processing involves identifying radicals and understanding their phonetic or semantic roles, while real-time character processing includes recognizing radicals and instantly comprehending entire characters’ meanings and pronunciations. This study’s first task focuses on radical processing, where CFL learners use radical knowledge to interpret multiple characters simultaneously. The second task extends …

Timing Is Everything: Congruence, Controllability, And Performance Measure Weighting, Hayden T. Gunnell, Gary Hecht, William B. Tayler, Kristy L. Towry

Faculty Publications

We investigate whether the weights managers place on performance measures for performancebased compensation depend on whether weights are determined at the beginning or end of the performance period. We propose that managers frame the weighting decision differently depending on timing. Specifically, prior to employee effort, managers frame the decision as intended to align employee effort to firm objectives, whereas after employees have exerted effort, managers frame the weighting decision as intended to evaluate employee effort. Thus, we expect, and find, that managers weight measures that are more congruent with firm objectives more heavily when weightings are determined ex ante (before …

Customer Service Operations: A Gatekeeper Framework, Maqbool Dada, Brett A. Hathaway, Evgeny Kagan

Faculty Publications

Customer service has evolved beyond in-person visits and phone calls to include live chat, AI chatbots and social media, among other contact options. Service providers typically refer to these contact modalities as “channels”. Within each channel, customer service agents are tasked with managing and resolving a stream of inbound service requests. Each request involves milestones where the agent must decide whether to keep assisting the customer or to transfer them to a more skilled – and often costlier – provider. To understand how this request resolution process should be managed, we develop a model in which each channel is represented …

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 …

Browsing Within An Academic Library, Holt Zaugg, Jillian Bunderson

Faculty Publications

Purpose – Browsing library resources is a method long used by researchers to expand their understanding of ill-defined projects and to have serendipitous research discoveries. This study sought to understand the browsing activities of students in an academic library. Design/methodology/approach – The study used two methods. First, a link to an online survey was posted on posters throughout the library inviting students to share their browsing experience. Second, library security officers (student employees) were asked to count the number of people browsing within the stacks as they conducted their hourly walk-throughs of the library. Browsing was broadly defined as anyone …

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.

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 …

Instructional Designer Perspectives On The Pursuit Of Quality In Online Course Design, Jason K. Mcdonald, Stephen C. Yanchar

Faculty Publications

In this qualitative study we investigated the experiences of instructional designers as they sought to build quality into online courses. Through semi-structured interviews, we explored what enabled and hindered their pursuit of quality, how they experienced their efforts in this regard, what mattered to them, and complexities that accompanied this pursuit. Our analysis of participant experiences suggested four themes: (1) connections between quality and designers’ ability to act autonomously; (2) connections between quality and collaborative, team-based relationships; (3) ambivalence due to tensions between autonomy and collaboration; and (4) ways of coping with limits on autonomy and collaboration. We conclude our …

Artificial Intelligence In Educational Research And Scholarship: Seven Framings, Eamon Costello, Giselle Ferreira, Stefan Hrastinski, Jason K. Mcdonald, Ahmed Tlili, George Veletsianos, Victoria I. Marin, Henk Huijser, Sharon Altena

Faculty Publications

In a recent interview (Bender et al., 2025), Professor Emily M. Bender discussed the limitations of technical solutions in addressing harmful Artificial Intelligence (AI) bias. She described a particular point we may reach at which technical solutions stop working, and when we should then widen the lens to ask about the problem framing itself. This is a crucial step in any inquiry that is of concern to both novice and experienced researchers alike: moving from problem-solving to problematisation. This commentary aims to provide educational researchers with a glimpse into the wide array of research problems and problematisation of AI in …

Disclosure Benchmarking By Lawyers: Evidence Fromthe Ipo Setting, Michael S. Drake, Jeff Mcmullin, Kenneth Merkley, Chase Potter, John Treu

Faculty Publications

Lawyers play an important advisory role in drafting financial reports, yet empirical evidence documenting the influence of external legal counsel on this process remains sparse. This study focuses on a specific aspect of lawyers’ drafting process: the practice of reviewing disclosures previously filed by other issuers—a practice termed “disclosure benchmarking.” Using initial public offering (IPO) disclosures as the setting, we find that disclosure benchmarking is associated with amore efficient Securities and Exchange Commission (SEC) review process. We further find that it is associated with several measures of disclosure quality, including disclosures that are less likely to be revised in subsequent …

The Information Content Of Private Information Acquisition: Evidence From Foia Requests To The Sec, Dichu Bao, Janja Brendel, Michael S. Drake, Lixin (Nancy) Su

Faculty Publications

We analyze Freedom of Information Act (FOIA) requests submitted to the Securities and Exchange Commission (SEC), focusing on the value-relevance hypothesis and the directtrading hypothesis. Our empirical analysis reveals nuanced value relevance associated with different types of requests: Requests related to ongoing investigations and submitted by anonymous requesters are negatively correlated with future returns, while requests from investment firms and intellectual property firms predict positive future returns. Our findings also provide some support to the direct-trading hypothesis, showing that investment firms increase holdings of stocks for which they have filed FOIA requests, and short sellers exhibit heightened activity following requests …

Signaling Innovation: The Nontax Benefits Of Claiming R&D Tax Credits, Bradford F. Hepfer, Hannah W. Judd, Sarah C. Rice

Faculty Publications

Using the IPO setting, we test whether firms signal the quality of their investments in innovation activities by claiming R&D tax credits. We find the presence and amount of the R&D credit are each associated with lower information asymmetry and with higher investor demand at IPO. Conservatively, we estimate that sample firms realize additional IPO proceeds of 32–45 percent of their creditable R&D expenditures, indicating economically significant non-tax benefits associated with the R&D credit. We verify the R&D credit signal by showing its positive association with firms’ future patenting activity, patent citations, and post-IPO stock returns. Results from these tests …

The Future Performance Implications Of Non-Gaap Motivated Investment, Minkwan Ahn, Theodore E. Christensen, Ryan G. Johnson, Melissa F. Lewis-Western

Faculty Publications

We investigate whether consistent non-GAAP reporting is associated with investment efficiency. Prior research finds a positive association between non-GAAP reporting and investment levels, concluding that it represents overinvestment. We corroborate this positive association, but additional tests are not consistent with the conclusion of inefficient overinvestment. Specifically, we explore the relation between investment and future cash flows as a proxy for the realization of investments in positive net present value projects. We find that the investments of firms that consistently report non-GAAP metrics are associated with similar or higher future cash flows than the investments of firms reporting only GAAP earnings, …

Price Transparency And Patient Engagement: Social Messaging Matters, Jace B. Garrett, Keaton C. Helquist, Steven D. Smith, William B. Tayler

Faculty Publications

OBJECTIVES: To examine the effects of price transparency and prosocial messaging on price-protected consumers’ health care choices as a potential cost-saving strategy to manage rising US health care expenditures.

STUDY DESIGN: Cross-sectional study. Participants were recruited to complete a basic questionnaire via Amazon’s Mechanical Turk program. Participants’ selections were subsequently collected and analyzed.

METHODS: Participants (N = 567) selected a sleep study provider from 5 options, with manipulations including financial responsibility, provision of price information, and a prosocial message encouraging high-value options.

RESULTS: Price transparency increased the selection of lower-cost options among participants who were solely responsible for paying for …

The Signaling Value Of Input Information: Performance Effects Of Task Difficulty And Effort Sensitivity, Steven D. Smith, William B. Tayler, Tyler F. Thomas, Todd A. Thornock

Faculty Publications

We investigate how the reporting of input information to managers affects employee performance, and how the signaling value of inputs for impression management moderates this effect. We develop theory to predict that the information content of input information (incremental to output measures), and thus its potential for impression management, will depend separately on both the difficulty of the task and the sensitivity of performance to effort. Across three experiments, we predict and find the reporting of input information significantly increases employee effort and performance in difficult relative to easy tasks and in low relative to high effort sensitivity tasks. Our …

Foreign Tax Holiday Participation And U.S. Job And Investment Loss, Zackery D. Fox, Linda Krull, Scott G. Rane

Faculty Publications

We investigate whether foreign tax holiday participation among U.S. multinational companies is associated with offshoring U.S. jobs and other domestic investment activities. We find that foreign tax holiday participation is associated with (1) an increase in offshoring U.S. jobs and (2) a decrease in domestic investment, as proxied by changes in the number of employees, capital expenditures, and R&D activity. Furthermore, we find evidence suggesting that the association between targeted, temporary tax incentives provided by foreign tax holidays and firms’ domestic activities is stronger among firms with a smaller foreign presence and is distinct from the impact of foreign statutory …

Redesigning Executive Incentives: The Rising Role Of Subjective Performance Measures, Zackery D. Fox

Faculty Publications

Despite the growing use of subjective performance incentives used in executive bonuses, empirical evidence on their effectiveness remains inconclusive. This study explores three aspects of subjective metrics in bonus plan design: their prevalence, the goals they target, and their impact on managerial behavior and firm outcomes. First, I document 53.8 percent of CEO bonus plans include at least one subjective performance measure, and among these plans, an average of 38.9 percent of total bonus weight is allocated to these measures. Using machine learning, I show subjective metrics target incentives related to employees, firm culture, and executive performance. Second, using the …

The Marginal Value Of Public Pension Wealth: Evidence From Border House Prices, Darren Aiello, Asaf Bernstein, Mahyar Kargar, Ryan Lewis, Michael Schwert

Faculty Publications

We study how state pension windfalls affect property prices near state borders, where theory suggests real estate reflects the value of additional public resources. Windfalls, representing a source of state revenue about half the size of total taxes, provide economically significant and plausibly exogenous variation in fiscal conditions. We find that each dollar of pension asset returns increases border house prices by approximately two dollars, suggesting that governments allocate additional funds towards high-value projects or tax abatement rather than wasting incremental resources. Evidence of larger effects in financially constrained municipalities highlights how fiscal resources amplify welfare effects of economic shocks.

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 …

Mill Power Consumption And Fuel Particle Size Distribution While Co-Milling Bituminous Coal With Steam-Exploded Woody Biomass In A Conventional Bowl Mill, Brian Schoof, Rajarshi Roy, Regan Kuttler, Parker Latour, Scott Montgomery, Jacob Tuttle, Gwendolyn Bennett Bennett, Brian D. Iverson, Andrew Fry

Faculty Publications

The mill behavior of a 312 Combustion Engineering Raymond Bowl Mill was studied with five blends of Utah bituminous coal and steam-exploded woody biomass, ranging from 100 % coal to 100 % biomass. Mill power consumption increased with biomass content, peaking at 187 % of the power required for 100 % coal before the mill faulted at 100 % biomass. After repositioning the rollers, power consumption for 100 % biomass decreased by 13 % compared to 100 % coal. SEM images revealed that milled biomass particles were non-spherical, indicating some fibrous structure remained post steam-explosion. The particle size distribution (PSD) …

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 …

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 …

Theses and Dissertations

The rapid expansion of oil and gas production in North Dakota’s Bakken Formation has heightened environmental concerns, particularly groundwater contamination from brine spills. Brine, a highly saline byproduct of oil extraction, poses a serious threat to water quality due to its chemical composition. This study examines brine spill impacts from 2013 to 2024 across Williams, Mountrail, McKenzie, and Dunn counties using GIS and the DRASTIC model, enhanced with Analytical Hierarchy Process (AHP) and Fuzzy Overlay techniques. Essential hydrogeological factors were analyzed to produce vulnerability index maps. Furthermore, spatial autocorrelation (Moran’s I), Optimized Hot Spot Analysis, and Emerging Hot Spot Analysis …

Comparative Analysis Of Lstm-Based And Traditional Hydrologic Models For River Discharge Prediction: A Case Study Of The Goose River, Adewale Ajao

Theses and Dissertations

Streamflow predictions are important in planning water resources and effective hydrological management. Physically based models such as the Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) have been used in the past for this purpose. Still, the use of machine learning models such as Long Short-Term Memory (LSTM) has been proven to complement the use of traditional models. This study compares the reliability performances of HEC-HMS and LSTM models to predict the streamflow of Goose River Watershed in North Dakota. The objective of the research is to perform a comprehensive comparative analysis between the performance of HEC-HMS and LSTM models to predict …
