Sharma, Nikhil (2011): Role of available and provided resources in sensemaking. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1807-1816. http://dx.doi.org/10.1145/1978942.1979204

Making sense of a topic often involves appropriating information and organizing themes from various existing resources. We studied how sensemakers appropriated from available online resources as well as artifacts provided by another person directly. We found that both available and provided resources affect sensemaking activities. Sensemakers added more structure in their work when online resources were easily available, but added less structure and information when they were provided relevant sensemaking artifacts from another person. We also studied how early and mature artifacts provided by another person were appropriated differently and found that mature artifacts were rated better and used more but resulted in lesser structure and information being added by the recipient. These findings have implications for the support of sensemaking activities using resources available online as well as artifacts provided by others including co-workers and friends.

Sharma, Nikhil and Butler, Brian (2011): Supercourse: a case study of knowledge mobilization by a virtual organization. In: Proceedings of the 2011 iConference 2011. pp. 770-771. http://dx.doi.org/10.1145/1940761.1940900

Information and knowledge are often stored not in databases repositories, but within highly distributed communities of experts. Leveraging these resources requires identifying needs and gathering, contextualizing and making information available. While this can happen in one-on-one interaction with experts, there are significant limitations to the dyadic approach. In this paper, we present our case study in progress which examines how Supercourse, a virtual organization focused on public health supports large-scale knowledge mobilization. Preliminary examination of this case suggests that social capital creation and genre usage play an important part in knowledge mobilization.

Huh, Jina, Nam, Kevin and Sharma, Nikhil (2010): Finding the lost treasure: understanding reuse of used computing devices. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 1875-1878. http://doi.acm.org/10.1145/1753326.1753607

In this paper, we report our findings on the adoption practices of used personal digital assistants (PDAs) to inform reuse of outdated computing products. Our interviews with 12 eBay users who bought used PDAs showed a variety of ways in which users indirectly supported sustainability. This allowed us to re-examine sustainability as something that is dynamically and arbitrarily shaped by the users and not just dependent on the sustainable feature of the product. We end with design implications for supporting users' shaping of sustainability.
