We used a theoretical conception of metaphor from cognitive linguistics to design an interactive system for viewing the citation network of the corpora of literature in the JSTOR database, a highly connected...
Qualitative coding offers the potential to obtain deep insights into social media, but the technique can be inconsistent and hard to scale.

Given the strong link between energy and behavior, sensing and metering per-user energy consumption is critical for understanding individual energy behavior and for customizing personalized feedback to promote energy-saving behavior. This paper explores the feasibility of per-user energy metering by proposing a per-user energy metering system that uses thermal-imaging and thermal-identification to...
