Witt rings of global function fields

open access: yesFunctiones et Approximatio Commentarii Mathematici, 2000
\textit{F. DeMeyer}, \textit{D. Harrison} and \textit{R. Miranda} [Mem. Am. Math. Soc. 394, 1--42 (1989; Zbl 0668.10028)] described the Witt ring \(W({\mathbb Q})\) of the rational number field \(\mathbb Q\) by defining the ring structure on an explicitly constructed set \(V(\mathbb Q)\) and showing that the rings \(W({\mathbb Q})\) and \(V(\mathbb Q)\)

Floral resource strips enhance parasitoid abundance and diversity in apple orchards and promote agroecological advances in a South African biosphere reserve

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 559-572, May 2026.
Floral resource strips within apple orchards increased parasitoid abundance and influenced community composition, enhancing local biodiversity in the Kogelberg Biosphere Reserve's transition zone. Ruderal and natural fynbos habitats supported higher parasitoid richness and abundance, emphasising the importance of conserving semi‐natural habitats ...

Adaptive and Maladaptive Behaviours and Their Cognitive Correlates in Aging Adults With Down Syndrome

open access: yesJournal of Applied Research in Intellectual Disabilities, Volume 39, Issue 3, May 2026.
ABSTRACT Background Longer life expectancy in Down syndrome (DS) has shifted concern to age‐related declines in everyday functioning. Adaptive and maladaptive behaviours are pivotal to quality of life, yet little is known about their patterns in older adults with DS.

Remittance Income and Crime in Mexico

open access: yesReview of Development Economics, Volume 30, Issue 2, Page 1299-1316, May 2026.
ABSTRACT This study examines the relationship between remittance inflows and criminal activity in Mexico, a country with persistently high crime rates and among the world's top remittance recipients. Using a 41‐quarter panel dataset of municipalities covering 2013–2023, the analysis estimates elasticity parameters linking remittance income to different
