ABSTRACT This research examines how the language of a charitable appeal influences bilingual consumers' prosocial intention and behavior. Drawing on the dual‐process model of sympathy and deliberation, we propose that native‐ and nonnative‐language appeals jointly activate emotive and cognitive routes to prosocial behavior.

A systematic review of avian influenza virus transmission models: Gaps and opportunities
Abstract Highly pathogenic avian influenza virus (HPAIV) increasingly threatens wild birds, poultry, non‐human mammals and humans, yet gaps and opportunities in avian influenza virus (AIV) transmission modelling have not been comprehensively synthesized.

Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

Overdischarge Induced Porous Graphite for Upcycling of Spent Lithium‐Ion Batteries
ABSTRACT The upcycling of spent lithium‐ion batteries (LIBs) into high‐performance materials offers both economic and environmental benefits. In this study, the principle of battery discharge‐induced copper dissolution and deposition is applied to fabricate a graphite/nanocopper composite anode.

ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

Evaluating the use of taxonomy in the IUCN Red List
Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk
