Survival Remains High in Griffon Vultures 40 Years After Reintroduction

open access: yesAnimal Conservation, Volume 29, Issue 3, Page 307-320, June 2026.
The reintroduction of the Griffon vulture (Gyps fulvus) in French Grands Causses in 1981 is largely regarded as a significant translocation success. 40 years of quality data from intensive monitoring allows us to investigate the survival rates in this long‐lived population on the long term, but also to reflect on the crucial role of adaptive management

Interactive Visualization of Diode Physics: Bridging the Fidelity‐Accessibility Gap in Web‐Based Engineering Education

open access: yesComputer Applications in Engineering Education, Volume 34, Issue 3, May 2026.
ABSTRACT In engineering education, a “fidelity‐accessibility trade‐off” persists: accessible web simulations often lack physical accuracy, while complex industrial tools impose heavy cognitive loads. This hinders effective instruction in semiconductor physics in remote, hardware‐constrained environments.

Norm Contestation in EU Foreign Policy: The Case of Sexual and Reproductive Health and Rights

open access: yesJCMS: Journal of Common Market Studies, Volume 64, Issue 3, Page 1190-1203, May 2026.
Abstract The EU considers gender equality fundamental to its identity, with Sexual and Reproductive Health and Rights (SRHR) playing a crucial role. This article delves into the contested aspects of EU foreign policy concerning SRHR from 1997 to 2021. Through document analysis and 18 semi‐structured interviews, it discerns three phases of contestation.
