Os Joelhos! Os Joelhos! Protective Embodiment and Occasional Injury in .

, the African-Brazilian dance and martial art has enthusiastic devotees in Britain. Most practitioners are acutely aware of their embodiment, and have strategies to protect themselves from injury, and ways to seek treatment for any injuries they get. Drawing on data from a long-term ethnography and a set of 32 open-ended interviews with advanced students, the paper explores student strategies to prevent injuries, and their discoveries of effective remedies to recover from them, before it presents an analysis of their injury narratives using Frank's three-fold typology of illness narratives.

Bringing tacit knowledge back to contributory and interactional expertise: A reply to Goddiksen.

We analyse a recent paper by Goddiksen (2014) where the author raises questions about the relationship between authorship, attribution and Collins & Evans' concept of contributory and interactional expertise. We then highlight recent empirical work in the sociology of climate change science that has made similar points in order to clarify how authorship, division of labour and contribution are handled in real scientific settings. Despite this, Goddiksen's critique of both contributory and interactional expertise is ultimately ineffective because it rests on a misguided attempt to de-socialise these concepts.
