Advanced Science, EarlyView.Circulating polyethylene microplastic burden is positively associated with heightened ADHD symptom severity and systemic redox‐inflammatory imbalance in children. Mechanistic investigation in a developmental co‐exposure mouse model further demonstrates that microplastics aggravate ADHD‐like behaviors, dopaminergic dysregulation, and oxidative ...

The Anatomical Record, EarlyView.Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how digital strategic orientation (DSO) and environmental practices (EP) interact to shape innovation and performance among Chilean SMEs. Using survey data from 271 firms (February–May 2022), we estimate a generalized structured component analysis (GSCA) model that accommodates a nonrecursive relationship between DSO and EP.
