Consequences of Individual‐, Organizational‐, and Societal‐Level Allyship: An Integrative Review and Recommendations for Policymakers and Practitioners

open access: yesSocial Issues and Policy Review, Volume 20, Issue 1, December 2026.
ABSTRACT Although allyship has the potential to foster inclusivity and bring about social change, its consequences have received too little attention in the literature. In the current contribution, we aim to review the allyship literature by focusing on the consequences of (1) individual‐, (2) organizational‐, and (3) societal‐level allyship.

Humpback Highs and Lows Amid Shifting Seas and a Northeast Pacific Marine Heatwave: Whale Demographics in the Main Hawaiian Islands, 2002–2023

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT North Pacific humpback whales are a celebrated conservation success, rebounding from extensive commercial whaling. Yet they remain vulnerable to the impacts of climate change, a multifaceted stressor that can exacerbate existing threats. During 2013–2016, a Northeast Pacific marine heatwave severely reduced forage availability in their feeding

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Inter‐Set Blood‐Flow Restriction Increases Peripheral Physiological Stress While Preserving Repeated‐Sprint Mechanical Output in Trained Athletes

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 9, September 2026.
ABSTRACT Inter‐set blood‐flow restriction (BFR) may increase the physiological stimulus of repeated‐sprint exercise without compromising mechanical output, but evidence in trained athletes is limited. In a randomized crossover design, 26 national‐level male badminton players completed three 5 × 5‐s cycling sprints (25‐s intra‐set rest, 3.5‐min inter ...

Preprocessing Procedure for Propagation Measurements on MEO Satellite Links

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 560-572, September/October 2026.
ABSTRACT This paper presents a software tool designed for preprocessing data from an experimental campaign aimed at characterizing the tropospheric propagation channel using Medium Earth Orbit (MEO) satellites. The collected data provide critical insights into the channel in scenarios involving continuous variations in azimuth and elevation, along with
