Roots of resilience: Assessing child and adolescent nature connectivity in the Mediterranean Region of Murcia (Spain)

People and Nature, Volume 8, Issue 2, Page 378-391, February 2026.
Abstract Children today spend less time outdoors than previous generations, with potential consequences for health, learning and pro‐environmental attitudes. We assessed children's connection with and exposure to nature in a Mediterranean setting using the Nature Connection and Experience Index (NCEI), a composite measure that integrates an affective ...

Fury and the antitheatrical prejudice: The violent power of play‐acting in the Cervantine picaresque

Orbis Litterarum, Volume 81, Issue 1, Page 11-26, February 2026.
Abstract The article studies a cross‐generic relation between theatrical performance and the outbreak of violence in picaresque contexts across works by Miguel de Cervantes. It then proceeds to contextualize these persistent incidents within the philosophical history of antitheatricality.

Heterobimetallic Pt(II) Complexes Supported by 1,8‐Naphthyridine Ligands Confirm the Rotation of C6F5 Groups about the Pt−C Bond

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
You Spin Me Round. The ligand 1,8‐naphthyridine is able to stabilize heterobimetallic complexes containing Pt(II)→M (M = Ag, Cu) donor–acceptor bonds, in which the rotation of the C6F5 ligands in solution can be stopped at low temperature. The ligand 1,8‐naphthyridine (napy) exhibits a rich coordination chemistry arising from the disposition of its two

Differentiating between F and OH Ligands in Homologous Gold(III) Complexes beyond X‐Ray Crystallography

European Journal of Inorganic Chemistry, Volume 28, Issue 34, December 1, 2025.
A subtle hydrogen‐bonding lock enables the unequivocal structural differentiation between fluoride and hydroxide in the unusual couple of homologous organogold(III) complexes [PPh4][(CF3)3AuF] and [PPh4][(CF3)3Au(OH)] (see adjacent figure). The homologous fluoride and hydroxide complexes of gold(III) [PPh4][(CF3)3AuX] [X = F (1), OH (2)] have been ...
