Time Out: A Scoping Review of Non‐Duration Based Social Media Use Measures and Adolescent Mental Health

open access: yesJournal of Adolescence, Volume 98, Issue 3, Page 659-677, April 2026.
ABSTRACT Introduction Research to understand the role of social media use (SMU) in explaining deteriorating adolescent mental health has been limited by broad, nonspecific measures of social media use, specifically ‘time spent on social media’. These measures provide insufficient detail to capture specific risk and protective factors to users.

Approach of the T-CONT Allocation to Increase the Bandwidth in Passive Optical Networks [PDF]

open access: yesRadioengineering, 2017
This paper works with the simulation of T-CONT allocation and delay analysis in passive optical networks PON. Building our networks with the PON technology we can achieve increased data rates, however we need to ensure that the idle gaps between the ...

Experience‐Sensitive Effects on Temporal Profiles of Social Attention in Early Childhood

open access: yesInfancy, Volume 31, Issue 2, March/April 2026.
ABSTRACT Bilinguals show differences in face processing compared to monolinguals, automatically orienting more rapidly to faces and dwelling longer on faces and mouths than monolinguals. However, it is difficult to identify specific visual strategies from average‐level data.
