The prevalence of food insecurity and its relationship with wellbeing in a large, cross‐sectional study of children and young people in England

JCPP Advances, Volume 6, Issue 2, June 2026.
Abstract Background We aimed to assess the prevalence of food insecurity reported by children and young people in four areas of England in 2023 and examine its association with mental health and wellbeing. Methods We used data from the OxWell student survey, a large, diverse, cross‐sectional study of 38,430 students aged 8–19 years, conducted primarily

A Machine‐Learning Classification for Torlesse Composite Terrane Petrofacies and its Application to Sediment Provenance

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The Torlesse Composite Terrane (TCT) forms many of the mountain ranges in Aotearoa New Zealand and has provided enormous quantities of coarse‐grained sediment to Te Riu‐a‐Maui/Zealandia's basins since the mid‐Cretaceous. Tracing the provenance of these sediments to certain regions of the TCT can indirectly reconstruct exhumation patterns associated ...

Enhancing Precision in PISA's 2022 Creative Thinking Assessment: Toward Aim‐Directed Item‐ and Factor‐Level Analyses

The Journal of Creative Behavior, Volume 60, Issue 2, June 2026.
ABSTRACT Large‐scale assessments often involve measurements with missing data where for a given student all items of a construct can be missing by design. In such circumstances, researchers are required to make methodological decisions in secondary analysis.

From Stability to Chaos: A Complete Classification of the Damped Klein‐Gordon Dynamics

Mathematical Methods in the Applied Sciences, Volume 49, Issue 9, Page 9696-9708, June 2026.
ABSTRACT We investigate the transition between stability and chaos in the damped Klein‐Gordon equation, a fundamental model for wave propagation and energy dissipation. Using semigroup methods and spectral criteria, we derive explicit thresholds that determine when the system exhibits asymptotic stability and when it displays strong chaotic dynamics ...
