Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

Chemistry – A European Journal, EarlyView.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.

Product‐Related CSR in the Digital Era: Communication Patterns That Drive Consumer Interactions on Social Media

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT To meet rising sustainability demands, companies increasingly use social media to communicate product‐related CSR initiatives. Consumers' interactions with these messages largely depend on the messages' perceived credibility. However, there remains limited understanding of how firms combine communication characteristics into distinct patterns ...

Humanlike AI for Corporate Social Responsibility Communication: How Perceived Anthropomorphism Shapes Stakeholder Acceptance of Chatbots

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Despite increasing interest in leveraging AI to improve CSR communication, there is limited understanding of consumers' reactions to chatbots in CSR communication. Building upon the HAII‐TIME model, this study proposes a theoretical model from the users' psychological perspective to explain facilitative pathways through which anthropomorphic ...

How to Milk a Yak: Embodied Learning with Yaks in Practice

Suomen Antropologi: Journal of the Finnish Anthropological Society
This essay is based on an ethnographic study at a self-subsistence-oriented yak herding village in Tibet (Tibetan Autonomous Region, China). I demonstrate how the social-biophysical profile and the life history of the researcher influences the research process–that is, how the individuality of the researcher’s body (e.g., gender, physical fitness ...
