"Conceptions of Work and the Materiality of the Classroom"

Daniel Carter

Infrastructure studies have focused attention on invisible work as a topic of concern for system design, pointing to the ways important roles may be lost if they are not recognized. This paper extends this engagement with invisible work by describing how conceptions of work in the classroom are influenced by material configurations. Based on ethnographic observations and a design intervention, I consider tensions between this invisible work and a group?s shared competence, arguing that altering material configurations can reveal invisible work and challenge existing conceptions and values. In the context of the collaborative work of the classroom this can result in the surfacing of individual perspectives that must be negotiated.

"Thematic Analysis of Words that Invoke Values in the Net Neutrality Debate."

Ken Fleischmann (joint work with Yasuhiro Takayama, An-Shou Cheng, Yoichi Tomiura, Doug Oard, and Emi Ishita)

This paper describes an initial analysis of the association of specific vocabulary choices with the invocation of human values in testimonies prepared for public hearings about Net neutrality in the United States. Motivation for this work comes from an interest in understanding what people value and how they express those values in writing. Related work includes research on human values from fields ranging from social psychology to advertising to human-computer interaction. First, human annotators used closed coding to identify human values in testimonies based on a prior meta-analysis of human values. Next, a ?values dictionary? was automatically learned that identifies words that are strongly associated with sentences that human annotators coded as being related to specific values. Finally, an open-ended thematic analysis was conducted. The contribution of the paper is to enhance our understanding of how human values are expressed, as well as to introduce and evaluate a new automated tool for facilitating social science research.

"Sustaining scientific infrastructures: transitioning from grants to peer production" (work-in-progress)

James Howison

Science now relies on mid-level infrastructure, including shared instruments, cell lines, supercomputing resources, data sets, and software components. These are beyond the facilities and services traditionally provided by individual universities; funding agencies such as the NSF often support their initial creation but their long-term sustainability is a challenge and commercialization is only rarely an option. A promising model, though, is broad-based community support through peer production, often inspired by the organization of open source software projects. Such transitions, though, are not automatic or easy, just as commercialization is not. In this research I am studying successful and unsuccessful attempts to transition, building theory and practical guidance for scientists and funding agencies. In this work-in- progress paper, I present the motivation and background for the study and provide motivation through preliminary description of my first case study.
