Congratulations to LUCI grad student Lynn Dombrowski on passing her advancement to candidacy exam!

The Role of e-Government Intermediaries in Access and Use of Government Nutrition Assistance Programs

“E-Government technologies are assumed to transform the relationship between citizens and their governments through creating new forms of interactions provided by the Internet, but there are few empirical examinations on how this transformation might take place for low-resource populations. In this work, I detail the social, informational, and technical practices of nonprofit workers, who I call “e-Government intermediaries”, in their work of assisting their clients with gaining access to and use of government nutrition assistance programs. I explore the four mediation activities these workers engage in to make the online application and government program a viable option for their communities: outreach, technological assistance, providing knowledge, and ongoing engagement. I then examine two major challenges that occur in their work of mediating government programs: access and trust. These two challenges directly relate to the mediation activities. The challenge of access relates the mediation activity of technical assistance. I detail the practical accomplishment of access, which enables outreach workers to perform technical assistance. The other challenge of the mediation activities is trust, which pervades all of the mediation activities, as it must be continually negotiated, but is most strongly associated with the mediation activity of outreach. Lastly, I articulate design implications to support these e-Government intermediaries’ and their practices that facilitate digital and social inclusion.”

Congratulations to Informatics faculty and researchers, Bill Tomlinson, Bonnie Nardi, Don Patterson and Six Silberman on having their paper, “Collapse Informatics and Practice: Theory, Method, and Design” accepted to a special issue of ToCHI focussed on ‘Sustainable HCI through Everyday Practices’

“What happens if efforts to achieve sustainability fail? Research in many fields argues that contemporary global industrial civilization will not persist indefinitely in its current form, and may, like many past human societies, eventually collapse. Arguments in environmental studies, anthropology, and other fields indicate that this transformation could begin within the next half-century. While imminent collapse is far from certain, it is prudent to consider now how to develop sociotechnical systems for use in these scenarios. We introduce the notion of collapse informatics—the study, design, and development of sociotechnical systems in the abundant present for use in a future of scarcity. We sketch the design space of collapse informatics and a variety of example projects. We ask how notions of practice—theorized as collective activity in the “here and now”—can shift to the future since collapse has yet to occur. ”

A new tech report has been posted to the LUCI tech report repository:

Playing with Genre: UserGenerated Game Design in LittleBigPlanet 2
by Joel Ross, Oliver Holmes, Bill Tomlinson

“Although computer and video games are traditionally understood as interactive experiences designed by professional developers, the increasingly social nature of these interactions means that players often become involved in the design process as well. In particular, games that include developer kits and level editors enable a form of participatory culture in which players directly perform usergenerated game design—creating their own game rules and challenges for other players—by means of “modding” or other design activities. We explore how players perform user-generated game design by analyzing player-designed levels in the popular game LittleBigPlanet 2, using game analysis to consider the design of selected levels and how those levels are presented to and viewed by other players. We describe how players create levels that build on the game’s existing genre, but also manipulate this genre to emphasize their own interpretations of what it means to play a video game. This study contributes an initial exploration of a form of end-user design that is of growing importance in video games, with potential implications for the design of future games and other participatory systems.”

Cultivating Environmental Systems Thinking with Karunatree - August 24th, 2012

A new tech report has been posted to the LUCI tech report repository:

Cultivating Environmental Systems Thinking with Karunatree
by Derek E. Lyons, Jennifer J. Long, Raminder Goraya, Jason Lu, Bill Tomlinson

“Understanding environmental issues requires an ability to see how concepts from many different STEM domains— biology, Earth science, physical science and more—fit together and interact as components of a larger whole. This integrative cognitive skill is sometimes called systems thinking (Doyle, 1997; Sweeney & Sterman, 2000). Unfortunately, though systems thinking is critical for understanding the state of the world we live in, it is also a challenging, counterintuitive skill to learn (Hmelo-Silver & Azevedo, 2006). This paper describes Karunatree: a web application designed to cultivate children’s scientific understanding of environmental issues. Karunatree seeks to support systems thinking in early- and pre-adolescent children (10-15 years old) by providing an intuitive means of visualizing how distributed webs of environmental cause and effect geographically intersect. Here we present a conceptual and technical overview of the Karunatree system, and evaluate its performance as part of a summer learning program for middle-school girls. By providing an example of how computational systems can support systems thinking, we hope to bolster future efforts to help children engage with complex environmental topics”

Computing Research for Sustainability - June 29th, 2012


Computing Research for Sustainability

LUCI friend, UCLA Prof. Deborah Estrin, chairs The National Academies’ Computer Science and Telecommunications Board. They just released a new report titled, “Computing Research for Sustainability”. From the press release:

“The report stresses that computer science research in sustainability must be an interdisciplinary effort, with experts in the various fields of sustainability being equal partners in research. To further that end, undergraduate and graduate education in computer sciences should provide experience across disciplinary boundaries. Programs should include tracks that offer course work in areas such as life-cycle analysis, agriculture, ecology, natural resource management, economics, and urban planning.” [citation]

Then in the report itself:

“This report emphasizes opportunities for research, in addition to the data and privacy challenges mentioned earlier, on human-centered systems both at the individual level and beyond (at the organizational and societal levels). Examples of such research areas include visualization and user-interaction design for comprehensibility, transparency, legitimation, deliberation, and participation; devices and dashboards for individuals and institutions; expanding the understanding of human behaviors, empowering people to measure, argue for, and change what is happening; and education.” [page 79 of the report]

It sounds like Informatics to me!

An interesting LUCI trivia point is that this report directly references a LUCI Tech Report, “Print This Paper, Kill A Tree: Environmental Sustainability as a Research Topic for Human-Computer Interaction” by it’s number LUCI-2009-004. I would guess that this is the highest profile publication to ever do that. Woot!

Update:  It turns out that Bill Tomlinson was a panelist during the information gathering stage for this report at the  Workshop on Innovation in Computing and Information Technology for Sustainability held at the National Academies in 2010.  He was also a reviewer of the document.

Interchange: An Analysis of Auction Mechanics for Intersections - June 18th, 2012

Congratulations to Nitin Shantharam who passed his M.S. advancement to candidacy exam with the paper:

“Interchange: An Analysis of Auction Mechanics for Intersections”

Abstract: In urban environments a large amount of effort is directed toward alleviating mo- tor vehicle congestion including the design and implementation of complex software and hardware infrastructure. We propose a conceptually simple infrastructure that has promise for increasing performance and responsiveness of intersections to dynamic traffic conditions. The proposed system uses an auction-based mechanism at intersections to alleviate traffic congestion. We discuss the reasoning and goals of implementing auction mechanics into intersections and set empirical expectations as to how such intersections should perform. Second, we compare our simulation of a traditional intersection and an auction-based intersection and propose metrics to track and evaluate such intersections. We demonstrate that auction-based intersections perform well in single and multi-grid configurations. Finally, we present our mesoscopic simulator capable of simulating real-world topographies and show that auction-based intersections show promise in more realistic systems as well.

Committee:

  1. Prof. Donald Patterson (chair)
  2. Prof. Bill Tomlinson
  3. Prof. Ramesh Jain

Computational Metaphor Identification - July 2nd, 2010

Moleskins and Pens

Assistant Project Scientist Eric Baumer, David Hubin, and Informatics Faculty Member Bill Tomlinson just released a tech report entitled
‘Computational Metaphor Identification’ which you can grab from here LUCI Tech Reports.

Abstract: Conceptual metaphors are pivotal to human cognition, but most previous computational linguistics treatments of metaphor focus on discerning a metaphor ’s literal meaning. Instead, this article presents computational metaphor identification (CMI), a technique for identifying potential conceptual metaphors in written text. This technique draws on and extends previous related work in cognitive linguistics and computational linguistics. CMI hinges on mapping selectional preferences from a source corpus to a target corpus in order to identify metaphorical mappings. Example results are presented and then evaluated via two methods: comparison with expert linguistic analysis, and assessment by non-expert human subjects. The results show that CMI is an effective means for identifying conceptual metaphors; computationally identified metaphors are shown to be conceptually similar to those identified in previous expert linguistic analysis, and confidence scores assigned by the system to identified metaphors correlate significantly with non-expert subjects’ assessments. This work represents a novel direction, both for computational linguistics research on metaphor, and for artificial intelligence research more broadly.

Congratulations Eric, David and Bill!
