Students' Emotional Responses to Mistakes: An Ecological Momentary Assessment Study in University Chemistry Laboratory

Science Education, Volume 110, Issue 6, Page 1613-1633, November 2026.
ABSTRACT This study explores students' emotions in the undergraduate chemistry laboratory, focusing particularly on emotional responses to making mistakes. Using an ecological momentary assessment design, we collected on‐task data from 240 students and 1635 learning situations during the laboratory sessions.

Beyond the Border Wars: Representation, Scale, and Multi‐Member Districts

Geographical Analysis, Volume 58, Issue 4, October 2026.
ABSTRACT Proposed redistricting reforms often focus on fixing gerrymandered maps or restructuring elections to boost proportionality. Recent work shows that, averaged across all 50 states, multi‐member districts paired with proportional ranked‐choice voting can deliver near‐proportional outcomes while curbing the gains available to a partisan map ...

Comprehensive review of short-term voltage stability evaluation methods in modern power systems

, 2021
The possibility to monitor and evaluate power system stability in real-time is in growing demand. Whilst most stability-related studies focus on long-term voltage stability and frequency stability, very little attention is given to the issue of short ...

Effects of Balance Training Combined With Either Transcranial Direct Current Stimulation or Stroboscopic Vision Training on Balance Performance in Individuals With Chronic Ankle Instability: A Systematic Review and Meta‐Analysis

Journal of Foot and Ankle Research, Volume 19, Issue 3, September 2026.
ABSTRACT Introduction Despite the benefits of balance training, persistent postural deficits remain common in individuals with Chronic Ankle Instability (CAI). The aim of this study investigates the efficacy of Stroboscopic Vision Training (SVT) and transcranial Direct Current Stimulation (tDCS) as adjunct modalities to improve balance in this ...

Projections of Climate‐Driven Changes in Fire Regimes and Implications for Boreal Landscapes in Alaska and Northwest Canada

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Boreal fire regimes in Alaska are expected to change with climate. Recent fire activity increased regional deciduous boreal forest fraction and decreased spruce, potentially foreshadowing landscape transformations that would affect habitat, ecohydrologic function, ecosystem services, and contribute to global climate feedbacks.

Effects of Dietary Activated Charcoal Supplementation on Performance, Egg Quality, and Bone Calcification in Laying Hens Exposed to High Fluoride

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 624-641, September 2026.
ABSTRACT The aim of the present study was to determine the effects of high dietary fluoride intake on performance, egg quality, serum biochemical parameters, bone tissue, mineral accumulation, and the expression of selected mineralisation‐related genes in laying hens, and to evaluate whether these effects could be alleviated by dietary activated ...
