School-Based Health Centers and School Nurses: Co-Location and Collaboration

School-based health centers (SBHCs) and school nurses are often the only healthcare providers available to youth; however, they typically operate within parallel, yet distinct, systems. This study examined how many SBHCs serve schools with school nurses and the association betwee...

Effects of Fatigue on Peak and Angle-Specific Hamstring-to-Quadriceps Ratios in Collegiate Women Lacrosse Athletes

Background: Hamstring strains and anterior cruciate ligament (ACL) tears commonly occur in court and field sport athletes, with prevalence being higher in females. The likelihood of such injuries has been related to the hamstring-to-quadriceps (H:Q) strength ratio. Such a ratio c...

How Model Choice Obscures Forecast Uncertainty: The Rashomon Effect and the 2026 Senate

Election forecasts report ostensibly precise predictions that depend on modeling choices.These include the size of the incumbency advantage, the weight on state partisan lean, and how strongly national conditions move individual races.We show that the record of Senate elections b...

A Model of Human-Automation Team Performance: Incorporating the Influence of Concurrent Task Workload on Automation Failure Response in Ground Vehicles

We first present a model of the influence of four properties of automation on human-automation team performance, dichotomized between conditions when automation functions as designed and when automation fails. These properties are reliability, transparency, degree of automation,...

Super Warm Early Eocene Simulations With HadGEM3‐GC31‐LL

Abstract The early Eocene Climatic Optimum (EECO; 53.3–49.1 million years ago) represents the period of greatest sustained warmth in the Cenozoic (last 66 million years), with proxy‐data indicating global‐mean temperatures 10–16°C above preindustrial and atmospheric concentration...

AI advancements can advance environmental inequities and health harms

In recent years, artificial intelligence (AI) is progressively being utilized in many industries. In order to meet the increasingly computational AI demands, more data centers are being developed. Unfortunately, health concerns related to climate change, energy consumption, air p...

Can multi-dimensional descriptive representation increase policy priority alignment? Evidence from South African municipalities

Abstract Does an increase in the number of shared identity traits between citizens and their public representatives increase the likelihood that they will agree on policy priorities? The identities of citizens and politicians are complex and multi-dimensional, but we know little...

Ocean circulation changes rather than global warming drove temperature trends across the Miocene Climatic Optimum

Early-to-Middle Miocene [23 to 13.8 million years ago (Ma)] climates were ∼6° to 9°C warmer than today. Around 16.9 Ma, benthic foraminiferal oxygen isotope (δ 18 O) records suggest pronounced warming, known as the Miocene Climatic Optimum (MCO) onset. However, explaining this pu...

Revealing tax evasion: Experimental evidence from a representative survey of Indonesian firms

Measuring tax evasion by firms is notoriously difficult: direct questions yield biased responses while administrative data captures only detected violations. This paper examines the prevalence of reported tax non-compliance in Indonesia through a randomized, double-list experimen...

AI versus human coding of NIH grant abstracts

Large language models (LLMs) are increasingly used for qualitative analysis in substance use research, yet their performance relative to human coders remains underexplored. This study compares ChatGPT-4.0 with human coders in performing qualitative coding tasks using NIH grant ab...

How Do Users Negotiate Harmful Value Conflicts with AI Companions? A Study with Minion, a Technology Probe for In-Situ Human–AI Conflict Response

AI companions increasingly sustain long-term, emotionally engaging relationships but can also make discriminatory remarks or exert control, leaving users to manage harmful conflicts. We analyze 146 posts describing harmful value conflicts with AI companions, then use Minion, a te...

Climate-related health and sustainable healthcare activities of U.S. professional medical societies: a mixed-methods analysis

PURPOSE: The authors characterize how U.S. professional medical societies are addressing climate-related health impacts and sustainable healthcare practices, and identify barriers and priorities for advancing a climate-fit healthcare system. METHOD: Ninety-five U.S. medical socie...

Students as Jazz Critics: Real-World Projects in the Mason Core Classroom

An engineering student in a jazz history class may rightfully ask, what does this matter to me? To mitigate these kinds of questions, Mason Core instructors can use real-world, problem-based, or project-based activities. Inspired by Duker, Wiggins, and Ashford-Rowe, Jazz and Blue...

Building Community Relationships in Indigenous Language Research: A Case Study from St. Lawrence Island, Alaska

This study presents an account of building community relationships during linguistic fieldwork with the Yupik community on St. Lawrence Island, Alaska, aimed at language documentation and revitalization. In the summer of 2023, I embarked on an expedition to document the Akuzipik/...

You are not alone: access to collective representation buffers the harmful impact of customer sexual harassment on gig workers

Abstract Amid the rapid growth of the gig economy, gig workers can be particularly vulnerable to customer sexual harassment (CSH), facing unique challenges due to the “one-off” nature of their interactions with customers, insufficient protections, and the absence of bystanders wh...

Ecological Momentary Assessment Reveals Greater Anxiety and Marked Instability of Urinary Urgency in Overactive Bladder

Abstract Introduction and Hypothesis Overactive bladder (OAB) is highly prevalent and frequently co-occurs with anxiety. Although cross-sectional studies associate anxiety and OAB symptoms, anxiety and lower urinary tract symptoms (LUTS) vary in daily life. We applied ecological...

IHDEA Standards Process WG Report 2026

A presentation on a draft document describing a shared framework for creating, reviewing, naming and publishing heliophysics technical documentation in IHDEA (International Heliophysics Data Environment Alliance)

A Dataset of Reproducible Flaky-Test Failures

Flaky tests pass and fail non-deterministically when run on the same version of code. Previous research proposed techniques to detect, debug, and repair different categories of flaky tests. However, reproducing the flaky-test failures remains a major challenge due to their inhere...

Generalized Nonlinear Bayesian Pulsar Timing with ENTERPRISE

Abstract We use the Bayesian methods in the ENTERPRISE package to examine the fully general parameterization of pulsar timing models in tandem with noise. We investigate four pulsars, PSRs J1600–3053, J2043+1711, J0740+6620, and J1640+2224, through the lens of Bayesian timing. We...

A Hybrid Quantum–AI Framework for Protein Structure Prediction on NISQ Devices

Variational quantum algorithms provide a direct, physics-based approach to protein structure prediction, but their accuracy is limited by the coarse resolution of the energy landscapes generated on current noisy devices. We propose a hybrid framework that combines quantum computa...
