Addressing The Challenges Of Cognitive Decline In The Physician Workforce, Sharona Hoffman Jan 2027

Addressing The Challenges Of Cognitive Decline In The Physician Workforce, Sharona Hoffman

Faculty Publications

This book chapter examines the growing challenge of cognitive decline among aging physicians and analyzes various approaches to addressing it. In 2024, twenty percent of working physicians were sixty-five or older, and evidence suggests that 12-14% of older clinicians have cognitive deficits that may affect job performance. The chapter evaluates two primary approaches to cognitive assessment: employer-initiated programs and programs operated by state medical boards. Employer "late career practitioner policies" (LCPP) that require older physicians to undergo testing are becoming increasingly popular among health care organizations. But they are vulnerable to challenge under disability and age discrimination laws, as evidenced …

A Square Peg In A Round Hole: Academic Review And Exhibitions, Cory L. Nimer, Megan E. Frost Sep 2026

A Square Peg In A Round Hole: Academic Review And Exhibitions, Cory L. Nimer, Megan E. Frost

Faculty Publications

Academic libraries increasingly use exhibitions as scholarly communication, yet conventional peer-review models rarely account for their collaborative, interdisciplinary nature. Museums and other GLAM institutions have developed standards addressing exhibition goals, audiences, interpretation, attribution, access, and visitor engagement, offering a useful foundation for academic library practice. At Brigham Young University, a library task force examined peer-review models across disciplines and adapted museum standards into a policy for evaluating exhibitions as scholarship in retention and promotion processes. Approved in January 2025, the policy was first applied to By Study and By Faith: 150 Years of BYU, an exhibition developed for the …


Methodological Variations In Environmental Justice Screening Tools And Their Impact On Disadvantaged Community Designations, Thomas Robbins, Qingran Li, Stephen Bird Sep 2026

Methodological Variations In Environmental Justice Screening Tools And Their Impact On Disadvantaged Community Designations, Thomas Robbins, Qingran Li, Stephen Bird

Faculty Publications

Government agencies in the United States have developed environmental justice screening tools (EJSTs) and designations to promote equitable distribution of benefits from environmental policies to disadvantaged communities (DACs). However, the methodological choices embedded in these tools, including the selection, weighting, and aggregation of environmental justice indicators, vary across EJSTs, and their implications for DAC designation outcomes are poorly understood. Here we systematically compare four EJSTs at the federal and state levels and show that these tools produce substantial variation in the DAC census tracts, with some tools emphasizing socioeconomic burdens while others prioritize environmental risks. Using quantitative regression models, we …


Uneven Surfaces, Chipped Plates And Hiding Spaces: Pedagogical Practices In The Nordic Outdoor Model Of Education, Karen Walker Sep 2026

This article shares insights from a professional study tour of Danish early childhood education programmes, examining how social pedagogical principles are embedded in outdoor learning environments. During June 2024, a group of early childhood teacher educators from the United States visited forest kindergartens, adventure playgrounds and natural playscapes in Denmark as participants in the Nordic Outdoor Model of Education study tour. Through guided visits and observations, we documented pedagogical practices that demonstrate the application of social pedagogy– particularly the integration of head, heart and hands in supporting children’s holistic development. This article connects observed practices to social pedagogical theory, highlighting …


Evaluating A Dual-Beacon Hartmann Turbulence Profiling Technique Using Wave Optics Simulations, Benjamin C. Wilson, Matthew Kalensky, Santasri Bose-Pillai, Jack E. Mccrae Aug 2026

Evaluating A Dual-Beacon Hartmann Turbulence Profiling Technique Using Wave Optics Simulations, Benjamin C. Wilson, Matthew Kalensky, Santasri Bose-Pillai, Jack E. Mccrae

Faculty Publications

Resolving how optical turbulence varies along a propagation path remains a key challenge for designers of free-space optical propagation systems. Instruments such as scintillometers and differential image motion monitors are commonly used, but only provide path-integrated turbulence estimates. Point sensors provide localized estimates of turbulence strength and can be used to generate path-resolved profiles when an array of point sensors are distributed along the optical path. However, this approach can be costly and complex to deploy in certain environments. Alternatively, a single point sensor can be mounted on a mobile platform that collects data while traversing the optical path, although …

Deporting Disability, Tania Valdez Aug 2026

Deporting Disability, Tania Valdez

Faculty Publications

Since the enactment of the earliest migration laws in the United States, people with disabilities have been targeted for exclusion and expulsion based on stereotypes that they are either dangerous or not productive. Although some of the pejorative language regarding disability in the Immigration and Nationality Act (INA) has changed over time, certain statutory provisions and the very structure of the INA still allow ableism to operate broadly in immigration adjudications. This Article focuses on the subtle, but pervasive, ways that immigration law disfavors noncitizens with disabilities. In particular, this Article examines ableism in the context of removal (commonly known …


An Atmospheric Optical Turbulence Structure Parameter Measurements System Based On Direct Ri Sensing Using High-Resolution Fiber-Optic Sensors, Matej Njegovec, Simon Pevec, Vedran Budinski, Boris Macuh, Melissa K. Beason, Denis Onlagic Aug 2026

An Atmospheric Optical Turbulence Structure Parameter Measurements System Based On Direct Ri Sensing Using High-Resolution Fiber-Optic Sensors, Matej Njegovec, Simon Pevec, Vedran Budinski, Boris Macuh, Melissa K. Beason, Denis Onlagic

Faculty Publications

The paper presents a method to characterize the refractive index structure parameter (Cn2) associated with optical turbulence directly. The characterization system is based on miniature, high‑resolution, all‑fiber refractive index (RI) sensors. The refractive index sensors employ open‑path, low‑finesse Fabry–Perot interferometers that are approximately 8 mm long and 200 μm in diameter. The active part of the interferometers is made of ultra‑low‑expansion glass, which eliminates the influence of thermal expansion on the refractive index measurements. The proposed refractive index sensor, operating in a differential configuration, achieved a resolution of 2×10-9 RIU using a custom‑designed spectral interrogation system …


Enhancing A Mid-Wave Infrared Fourier Transform Hyperspectral Imager For Explosions, James T. Stofel, Kody A. Wilson, Martin Larivière-Bastien, Anthony L. Franz, Michael L. Dexter Aug 2026

Enhancing A Mid-Wave Infrared Fourier Transform Hyperspectral Imager For Explosions, James T. Stofel, Kody A. Wilson, Martin Larivière-Bastien, Anthony L. Franz, Michael L. Dexter

Faculty Publications

Capturing reliable hyperspectral imager data at a meaningful frame rate for explosions and other fast-changing scenes is not possible in the mid-wave infrared region under traditional sensor operating configurations and processing techniques, which typically have frame rates on the order of 0.5–2.0 Hz. To combat these shortcomings, the scene acquisition parameters were tailored for explosions and a new method for processing optical signatures of fast transient scenes with Fourier-transform infrared hyperspectral imagers was developed. For this technique, the instrument was first configured to collect asymmetric interferograms while optimizing the number of measurement points on the short side of the interferogram. …


Terahertz Electromagnetic Effects And Chirality-Induced Spin Selectivity In Dna, F. Matthew Mihelic Md Aug 2026

Terahertz Electromagnetic Effects And Chirality-Induced Spin Selectivity In Dna, F. Matthew Mihelic Md

Faculty Publications

The effects of terahertz electromagnetic stimulation of the DNA molecule can be understood through modeling of the quantum logical mechanics of the DNA molecule.  Coherent conduction of electron spin states along the aromatic nucleotide base pairs and chirality-induced spin selectivity are two characteristics of the DNA molecule that are involved in the precise separation of the double-stranded DNA molecule at a specific location.  Such modeling can inform predictions of DNA strand separation and has significant implications for understanding DNA transcription bubble formation.

Modeling Formation Of Turbulent Sporadic-E Clouds Using Realistic Wind Data, Aaron M. Schinder, Kenneth S. Obenberger, Jorge L. Chau, Juan M. Urco, Matthias Clahsen, Benjamin F. Akers, Daniel J. Emmons

Faculty Publications

A high resolution two-dimensional multi-fluid model of sporadic-E layers was developed and driven with physically realistic mesosphere, lower thermosphere (MLT) winds measured over Albuquerque, New Mexico. The realistic E-region winds are produced by the HYdrodynamic Point-wise Environment Reconstructor (HYPER) model that ingests meteor derived wind observations from a Spread-spectrum Interferometric Multistatic meteor radar Observing Network (SIMONe) system combined with the Navier-Stokes equations to provide high resolution three-dimensional wind fields over time. Sporadic-E dynamics are simulated using both realistic winds from HYPER as well as idealized hyperbolic tangent windshears to compare and contrast. Overall, the model shows greater inhomogeneity and irregularity …

The Long Arc Of Global Citizenship: Historical Foundations, Modern Challenges, And Institutional Innovation At Rollins College, Wenxian Zhang

Faculty Publications

The concept of global citizenship can be traced back to the Greek and Roman periods in Western civilization, as well as to ancient Eastern philosophies. Representing both a prescriptive ideal and an aspirational faith in humanity, the notion is closely linked to the historical development of cosmopolitanism, transnationalism, and transnationality. This study first reviews the rich historical roots and core values of global citizenship, along with the growing need for global citizenship education in the modern era. It then highlights several influential individuals who strongly championed its principles, including theoretical physicist and Nobel Prize winner Albert Einstein and internationalist and …

Nitrate Levels In The Tap Water Of Several Northeast Iowa Communities In 2026, Kamyar Enshayan Aug 2026

Nitrate Levels In The Tap Water Of Several Northeast Iowa Communities In 2026, Kamyar Enshayan

Faculty Publications

Tap water samples were taken from numerous sites in several northeast Iowa communities along the Cedar River to learn what levels of nitrate people are actually drinking over a several-months period in 2026, with the hope of inspiring public conversations, understanding and action. Samples were taken from February to June 2026.  None of the tap water samples violated the current outdated nitrate limit of 10 mg/l set 35 years ago. However, published public health studies in the past 15 years reveal that consuming nitrate in drinking water at levels as low as 5mg/l for a long time can increase the …


Healer Or Human? How Online Physician Reviews Guide Patient Choice, Shabnam Azimi, Sina Ansari, Ignacio Luri, Atefeh Yazdanparast Jul 2026

Healer Or Human? How Online Physician Reviews Guide Patient Choice, Shabnam Azimi, Sina Ansari, Ignacio Luri, Atefeh Yazdanparast

Faculty Publications

Online reviews increasingly guide physician choice, yet it remains unclear whether content emphasizing a physician's competence (technical skills) or benevolence (prioritizing patients' welfare over self‐interest) more strongly influences patients' decisions. Integrating a field study of 12,351 physician reviews with two online experiments, we distinguish two dimensions of review effectiveness: how helpful readers find a review, and how confident they feel about the choice it informs. We show that competence‐ and benevolence‐focused content influences these outcomes through distinct mechanisms. Benevolence‐focused reviews receive higher helpfulness evaluations because caring behaviors are easier to describe in concrete, vivid language and because naturalistic review platforms …


Ai-Powered Resume Screening, Sang Suh, Numery Zaber Jul 2026

Ai-Powered Resume Screening, Sang Suh, Numery Zaber

Faculty Publications

Traditional resume screening is manual, slow, and susceptible to bias, and it struggles to keep pace with today’s application volumes. This paper presents a dual-engine, AI-powered resume screening system designed for transparency and reproducibility. The primary (classical) pipeline encodes resumes and job descriptions using Sentence-BERT (SBERT), computes a resume–job match score via cosine similarity, classifies candidates into 25 job categories using XGBoost, and provides model interpretability through SHAP. In parallel, a prompted large language model (LLM) baseline (GPT-4o/4o-mini) outputs a match score and predicted category for comparative analysis. A Streamlit-based interface integrates both engines to support recruiter workflows and human-in-the-loop …

Regulating Manipulative Design Is Not Preempted By Cda 230 Or The First Amendment, Brett Frischmann, Peter Ormerod Jul 2026

Regulating Manipulative Design Is Not Preempted By Cda 230 Or The First Amendment, Brett Frischmann, Peter Ormerod

Faculty Publications

For over two decades, there has been a heated debate among legal scholars, activists, judges, and others about the scope of Section 230 of the Communications Decency Act. A persistent theme in those debates has been hyperbolic claims about the necessity of immunity from state laws for digital tech platforms and fearmongering that anything less than maximum immunity will destroy the Internet.

This Article argues that states retain considerable discretion to regulate digital platforms’ design and engineering decisions. We argue that manipulation, engineered behavior, and even habituation and normalization of engineered behavior by digital platforms are content-agnostic harms attributable to …

Comparative Analysis Of Task Scheduling In Multi-Tier Fog-Cloud Computing: From Classical Approaches To Greedy Multi-Objective Optimization, Zafril Rizal M. Azmi, Najmul Haque, Saydul Akbar Murad Jul 2026

Comparative Analysis Of Task Scheduling In Multi-Tier Fog-Cloud Computing: From Classical Approaches To Greedy Multi-Objective Optimization, Zafril Rizal M. Azmi, Najmul Haque, Saydul Akbar Murad

Faculty Publications

Fog computing extends cloud services to the network edge, enabling low-latency processing for time-sensitive applications. However, scheduling complexity significantly increases due to heterogeneous resources, dynamic workloads, and strict Quality-of-Service (QoS) constraints. Although numerous scheduling techniques have been proposed, existing studies often assess only a narrow subset of algorithms or rely on offline metaheuristics unsuitable for real-time environments. This paper presents a comprehensive comparative evaluation of twelve scheduling algorithms, including five classical, one heuristic, and six metaheuristic-inspired approaches, within a realistic 20-node multi-tier fog-cloud topology. Across 1,365 experiments spanning seven utilization levels, we analyze each algorithm’s deadline adherence, load distribution, and …

This study examines how mothers raising children with disabilities in American Samoa experience the processes of seeking diagnosis, navigating special education, and advocating for services within an insular rural context. American Samoa, an unincorporated U.S. territory located 2600 miles from Hawaiʻi with a population under 50,000, represents a case of what we term insular rurality—a condition in which the structural disadvantages of rurality are intensified by oceanic isolation, territorial governance, and colonial history. Data were collected through three focus groups with fifteen mothers whose children hold a range of disability diagnoses, with a card sort activity at the outset of …


Institutional Influences And The Governance And Administration Of The Programa Produtor De Água Payment For Ecosystem Services Program In Brazil, Thomas G. Safford Jun 2026

Institutional Influences And The Governance And Administration Of The Programa Produtor De Água Payment For Ecosystem Services Program In Brazil, Thomas G. Safford

Faculty Publications

Payment-for-Ecosystem-Services (PES) has been promoted as an innovative approach to environmental governance capable of simultaneously advancing conservation and sustainable development objectives. While studies commonly assess the ecological and economic performance of PES schemes, less attention has been given to their organizational and administrative effectiveness. This study examines these governance dimensions of one of Latin America’s most prominent PES initiatives—the Water Producer Program (WPP) in Brazil. Drawing on a meta-synthesis of 125 publications, the analysis investigates how regulative, normative, and cultural-cognitive institutional forces shaped WPP implementation. Guided by neo-institutional theory and institutional bricolage, findings show that WPP governance operated through hybrid …


From Centrality To Sustainability: How Connected Boards Shape Waste Management Outcomes, Irfan Haider Shakri, Anh Tuan Nguyen, Fnu Pratima Jun 2026

From Centrality To Sustainability: How Connected Boards Shape Waste Management Outcomes, Irfan Haider Shakri, Anh Tuan Nguyen, Fnu Pratima

Faculty Publications

The escalating climate crisis has elevated waste management from an operational concern to a critical issue of corporate governance. However, the role of board connectedness in shaping firms' waste practices remains largely unexplored. Drawing on resource dependency and social capital theories, this study examines how board network centrality influences waste management practices. Employing pooled OLS on 4948 firm- year observations from US- listed firms during 2004–2023, we find that higher board connectedness leads to a significant reduction in waste generation. Economically, a one standard deviation increase in DEGREE centrality is associated with a 3.4% decrease in total waste generation. Our …

Assessing Planetiq Gnss-Ro Ionospheric Electron Density And Tecusing Ground-Based Ionosondes And Cosmic-2, Mohammed Alheyf, Mohamed S. Yamany, Ibrahim F. Ahmed

Faculty Publications

Radio occultation (RO) has become a key technique for monitoring the ionosphere by deriving electron density (Ne) profiles and total electron content (TEC) from GNSS signals. This study assesses the newly deployed PlanetiQ GNOMES constellation by validating its ionospheric Ne profiles and profile-based TEC against collocated measurements from ionosondes and the COSMIC-2 mission under both quiet and disturbed geomagnetic conditions. Data matching for the statistical validation uses conservative spatial thresholds of less than 1◦ in latitude and longitude and temporal limits of 30 min for ionosondes and 1 hfor COSMIC-2, supported by a dedicated sensitivity analysis, whereas storm-time case studies …


Dodosolsollalasol: Theme And Variations, Myrna J. Layton Jun 2026

Dodosolsollalasol: Theme And Variations, Myrna J. Layton

Faculty Publications

The 2020 Korean Drama DoDoSolSolLaLaSol takes its name from, and makes substantial use of, the tune otherwise known as “Ah, vous dirai-je, Maman,” the French Folk Song whose tune Mozart used in his twelve variations, and in English as “Twinkle, Twinkle Little Star.”

The text of “Ah, vous dirai-je, Maman,” focuses on the relationship between parent and child, which is one of the thematic applications of the music in the Korean drama. However, the French children’s song’s tune is taken from an earlier French song intended for adults, “La Confidence Naïve,” which is about a romantic relationship. This is another …


Matching Two Long Interferometric Pathlengths Using Low Temporal Coherence Light For Finding Hong–Ou–Mandel Dip, Keith A. Wyman, Noah S. Everett, Anil K. Patnaik Jun 2026

Matching Two Long Interferometric Pathlengths Using Low Temporal Coherence Light For Finding Hong–Ou–Mandel Dip, Keith A. Wyman, Noah S. Everett, Anil K. Patnaik

Faculty Publications

Hong–Ou–Mandel (HOM) dip from a biphoton source in a two-photon interferometer provides a myriad of quantum tools for quantum communication and sensing. But the stringent requirements for spatial coherence between the photon pair makes it prohibitively difficult to observe high-fidelity HOM dip in long-distance free-space implementations, e.g., for the photon pairs involved in quantum communication need to match the two path lengths within a few 10 s of micron because of the short coherence width of the two-photon wave-packet. While many techniques for the pathlength balancing of two interferometric arms have been studied and applied extensively, such balancing is further …

News Media Coverage Of Measure Ula: How The Story Of La’S Big Project To Address Homelessness And Affordable Housing Got Sidetracked By The Story Of Big Real Estate, Christopher R. Martin

Faculty Publications

“Measure ULA,” named after United to House LA, was approved by voters in Los Angeles in 2022 to create a dedicated, long-term funding source for solutions to homelessness in LA, including funding the construction of affordable homes and preventing homelessness by helping tenants stay in their homes. The funding would come from a new tax on the most expensive real estate transactions in L.A. (i.e., mansion tax), and would affect fewer than 4% of all property transactions. At the end of three years of local news coverage about Measure ULA from the Los Angeles Times and LAist, the news audience …


Backscattering By Particles Of Sizes <0.2 Μm In Seawater, Xiaodong Zhang, Yuanheng Xiong May 2026

Backscattering By Particles Of Sizes <0.2 Μm In Seawater, Xiaodong Zhang, Yuanheng Xiong

Faculty Publications

We measured the angular scattering functions at 517 nm in different size fractions, including bulk and very small particles (VSP for diameters <0.2 μm), in a variety of waters ranging from coasts to open oceans and from surface to depths as deep as 3,000 m. The measurements revealed a strong covariation in backscattering between VSP and bulk particle populations. The fractional contribution by VSP decreases from 60% in clear oceanic water where bulk particle backscattering coefficient bbp is on the order of 0.001 m−1 to <2% in turbid coastal water where bbp ∼0.1 m−1. An empirical model is developed (r2 = 0.89) to estimate bbp for VSP from the bulk bbp, which can now be routinely obtained from satellite observations.
