We propose that corporations should be subject to a legal obligation to identify and internalise their social costs or negative externalities. Our proposal reframes corporate social responsibility as obligated internalisation of social costs, and relies on reflexive governance through mandated hybrid fora. We argue that our approach advances theory, as well as practice and policy, by building on and going beyond prior attempts to address social costs, such as prescriptive government regulation, Coasian bargaining and political CSR.

This article examines the Dobsonian Telescope as an object of material culture, showing how starting with the materiality of a scientific instrument opens up new perspectives that are lost by focusing purely on its instrumentality. It argues that the simple design and homely materials of the Dobsonian telescope, as well as the gestures that it requires from its users, are at the core of its significance to the popularization of amateur astronomy and amateur telescope making.
