Context “Matters”: Issues of Personal Values, Local Politics, and the Superintendency

Superintendents are asked to make decisions that are in the best interest of K–12 public school children, families, and communities, all while considering the involvement of internal and external influences. This often requires leadership that challenges superintendents’ professi...

Star Wars at Fifty

This symposium celebrates the 50th anniversary of Star Wars (1977) with nineteen short essays from scholars who discuss its meaning, impact, and legacy. The essays examine the migrations and manifestations of the Star Wars universe across media, including animation, video games,...

Adaptive Tracking Control for Underactuated Lunar Hopping Vehicles

This paper develops two different adaptive control solutions for a propulsive exploration lunar hopping vehicle along with their performance characterization. Full six-degree-of-freedom error dynamics relative to an a priori defined reference trajectory are outlined for controlle...

An open-source, physics-aware, data-driven tool for automated particle image velocimetry post-processing

Particle image velocimetry (PIV) is a powerful diagnostic tool for analyzing the properties and structures of laminar and turbulent flows. Modern PIV systems provide high spatial and temporal resolution measurements, often generating hundreds of gigabytes of raw data. Before thes...

Point/Counterpoint on the Controversial 2025–2030 Dietary Guidelines for Americans

The 2025-2030 Dietary Guidelines for Americans (DGAs) issued nutrition recommendations, some of which have been praised by the nutrition community while others have been questioned based on the lack of supporting evidence. The recommendations about calorie control, emphasis on nu...

Handling within-study variability in moderators and dependence in correlation coefficients: Meta-analytic structural equation modeling

Meta-analytic structural equation modeling (MASEM) is a flexible modeling framework that combines the strengths of meta-analysis and structural equation modeling. Despite the increasing popularity of the MASEM technique, its usage and scope are limited to relatively simple meta-a...

Nouns and nominalization as choices of style

John Eric Bellquist examines nominalization and noun strings as choices of style in professional writing. Through examples from nursing literature, he shows how nouns can name useful concepts while verbs, possessives, and prepositions can clarify actions and relationships. The be...

The Evolution of Low-ionization Electron Densities in Galaxies across Cosmic Epochs

Abstract We investigate the low-ionization electron density in the interstellar medium (ISM) of galaxies across 0 < z < 8, derived with the [O ii ] λλ 3727, 3730 and [S ii ] λλ 6718, 6733 doublets, using both deep JWST/NIRCam/grism and NIRSpec/MSA spectroscopy. Along with ancilla...

Innovation adoption across regions: psychological openness and the early diffusion of digital platforms

Early regional adoption is crucial for platform-enabled innovations because their viability depends on enough people within a region adopting them to generate network effects. Existing research on regional innovation diffusion explains early adoption largely through demographic,...

Constraining Dust Formation in the Superluminous Supernova 2017gci with JWST Observations

Abstract We present JWST/MIRI observations of the Type I superluminous supernova (SLSN) 2017gci obtained over 2000 rest-frame days after the supernova (SN) exploded, which represent the latest phase images taken of any known SLSN to date. We find that archival Wide-field Infrared...

Harnessing Photoexcited-State Pathways in Boron Dipyrromethene for Phototheranostics and Photopolymerization

Abstract Boron dipyrromethene (BODIPY) dyes are widely recognized for their strong visible-light absorption, high fluorescence, and structural modularity. Beyond fluorescence, molecular engineering can redirect their photoexcited states toward distinct photochemical pathways, exp...

Bayesian local clustering of functional data via semi-Markovian random partitions

We introduce a Bayesian framework for indirect local clustering of functional data, leveraging B-spline basis expansions and a novel dependent random partition model. By exploiting the local support properties of B-splines, our approach allows partially coincident functional beha...

Practitioner-Researcher Positionality: Beyond Statements in Educational Leadership Doctoral Research

Researcher positionality is widely acknowledged in qualitative research but is often reduced to identity disclosures with limited insight into how research decisions shaped the inquiry process. This article conceptualizes practitioner-researcher positionality in educational leade...

Preparation for bias conversations among Black/African American, Latinx, and Asian parent‐adolescent dyads: A qualitative content analysis of observational data

Abstract Preparation for bias conversations may be critical in raising youth awareness of racial‐ethnic discrimination, fostering a strong racial‐ethnic identity, and teaching them how to cope or respond to racialized stressors. However, the literature relies almost exclusively o...

Fluorinated Aromatic Diluent Enabling Stable and Non–flammable Phosphate Electrolytes for Sodium Metal Batteries

ABSTRACT The development of non–flammable electrolytes for sodium metal batteries (SMBs) presents a promising path toward enhancing energy density and safety, especially for large–scale grid storage applications. While high–concentration phosphate electrolytes have been reported...

Real-World Versus Centers for Medicare and Medicaid Services Estimates of Pediatric Retinal Detachment Repair Times

Purpose: To compare real-world pediatric retinal detachment (RD) repair times with the Centers for Medicare and Medicaid Services (CMS) estimates for complex RD surgeries. Methods: A cross-sectional survey was performed of complex pediatric RD perioperative times from pediatric r...

Multicomponent PFCAs Capture, Detection, Differentiation, and Aqueous-Phase Removal with Adaptive Luminescent Organic Cages

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are persistent, nonbiodegradable pollutants that accumulate in water, posing threats to human health and aqueous ecosystems. There is currently a need for technologies capable of both multicomponent detection and removal of PFA...

Sustainable solar water purification: Exploring the structural advantages of higher plants

Solar vapor generation is a promising technique for water purification, although the development of efficient and sustainable systems for practical use remains challenging. Here, we introduce a higher plant–derived evaporator, leveraging the structural advantages of plants and th...

Unveiling Hidden Patterns in Electrode‐Electrolyte Interphase Chemistry and Architecture Through Machine Learning‐Assisted Mass Spectrometry Analysis

Electrode-electrolyte interphases (EEIs) govern battery performance, yet the interplay between their chemical composition and spatial organization remains challenging to resolve. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) provides rich 3D chemical depth profiles of...

Data-Driven Prediction of Speech-in-Noise Performance: A Systematic Review and Meta-analysis of Machine Learning Models

PURPOSE: Difficulty understanding speech in noise (SIN) is a major determinant of communication ability and quality of life, affecting individuals with hearing loss as well as some with normal hearing. Data-driven prediction methods offer a promising approach for modeling complex...
