I have been reading an influential essay by Arjun Appadurai, ‘Introduction: commodities and the politics of value’ from Appadurai, A. (ed.) (1986) The Social Life of Things: Commodities in Cultural Perspective. Cambridge: CUP, pp. 3–63.
Although focused on ‘commodities’ which implies an economic context that is missing (overly at least) from the NHS context, points in the essay have made me think about how one might frame a critical study of gratitude and the giving of gifts to healthcare professionals.
It is not customary to give gifts in the NHS (although this needs further research). Most anthropological studies of gift-giving are focused on the trajectory of gifts within relatively isolated, small-scale societies.
