Identifying Factors Influencing the Implementation of Early Intervention Services for Psychosis in Quebec, Canada: A Qualitative Study of Health Care Providers' Perspectives

open access: yesEarly Intervention in Psychiatry, Volume 19, Issue 10, October 2025.
ABSTRACT Introduction Early intervention services for psychosis are clinically and cost‐effective. Despite the availability of national and international guidelines and well‐identified essential components of high‐quality services, the implementation of early intervention services varies greatly. However, factors underpinning this are poorly understood

Terrestrial Spatial Distribution and Summer Abundance of Antarctic Fur Seals (Arctocephalus gazella) Near Palmer Station, Antarctica, From Drone Surveys

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
A summer population of nonbreeding Antarctic fur seals arrives each year at the west Antarctic Peninsula, but remains poorly characterized amid the rapid climatic and ecological changes that are restructuring the region's environment and food web. We carried out a campaign of drone surveys to map the occurrences of Antarctic fur seals across a variety ...

Impact of Ionospheric Scintillations on GNSS Availability and Precise Positioning

open access: yesSpace Weather, Volume 23, Issue 2, February 2025.
Abstract For many applications where accuracy, availability, and integrity are essential, such as geodetic positioning and civil aviation, Global Navigation Satellite Systems (GNSS) are indispensable. However, GNSS signal dependability is severely hampered by ionospheric disturbances, especially equatorial plasma bubbles (EPBs), particularly in ...
