This paper explores the nature and centrality of maintenance and repair ('M&R') work in the extension and sustainability of ICT infrastructure in the global South. Drawing from pragmatist traditions in CSCW and the social sciences at large, we develop a concept of 'repair worlds' intended to map the varieties and effects of such maintenance and repair(More)
The interstitialcy theory is used to calculate the kinetics of shear modulus relaxation induced by structural relaxation of metallic glasses. A continuous distribution of activation energies is shown to be a salient feature of the relaxation. High precision in situ contactless electromagnetic acoustic-transformation shear modulus (600- kHz) measurements(More)
Museums and other out-of-school settings, are ideal contexts for children to engage in authentic scientific inquiry. However, students need support to successfully do inquiry outside of the classroom, and to make connections between what they are learning in and outside of school. Zydeco is a new system that aims to support students in seamlessly conducting(More)
Repair and maintenance haunt the margins of ICT and development ('ICTD') and broader information school scholarship, but have rarely received central theoretical or empirical attention in the field. This paper attempts to fill this gap. Theoretically, it explores ideas from the growing but scattered body of social science work around infrastructure,(More)
