Grounding spatial language in perception: an empirical and computational investigation.

The present paper grounds the linguistic cdategorization of space in aspects of visual perception; specifically, the structure of projective spatial terms such as above are grounded in the process of attention and in vector-sum coding of overall direction. This is formalized in the attentional vector-sum (AVS) model. This computational model accurately predicts linguistic acceptability judgments for spatial terms, under a variety of spatial configurations. In 7 experiments, the predictions of the AVS model are tested against those of 3 competing models. The results support the AVS model and disconfirm its competitors. The authors conclude that the structure of linguistic spatial categories can be partially explained in terms of independently motivated perceptual processes.     

Global ethics: a short reflection on then and now

Ten years on from the first issue of the Journal of Global Ethics, Darrel Moellendorf and Heather Widdows reflect on the current state of research in global ethics. To do this, they summarise a recent comprehensive road map of the field and provide a map of research by delineating the topics and approaches of leading scholars of global ethics collected together in the recently published Routledge Handbook of Global Ethics which they have co-edited. Topics fall under issues of war, conflict and violence; poverty and development; economic justice; bioethics and health justice; and environmental and climate justice. In all these areas, ethicists are becoming ever more engaged in the details and mechanisms of actually delivering justice in the real world.
