The latest issue of Dialogues in Human Geography is now online (requires subscription). It includes a piece from John Allen entitled ‘Topological twists: Power’s shifting geographies’ with responses from Anssi Paasi, me, Mat Coleman and Alan Latham. There is also a piece by Wendy Larner with responses; and a couple of book review forums, one of which is on Jane Bennett’s Vibrant Matter: A Political Ecology of Things.
