We differentiate between these user types and analyze patterns of sourcing and routing information among them.

Often these live performances, even with a solid foundation in vocal pedagogy, can be very taxing to the vocal mechanism, causing strain and injury. Working without a drummer largely solves this problem, but introduces other difficulties regarding maintaining rhythmical energy. Research was undertaken in the areas of composition, new interpretations and arrangements of existing works (including a broad literature search for supporting works), personal technical development, and development of rhythm section strategies. Research Contribution: On Impulse comprises ten tracks, three of them original compositions, that set new benchmarks for the discipline through improvisation, impromptu interplay and interconnection within live musical performance, and arranging strategies for rhythm sect...

By synchronizing light and vibrations with users' personal heartbeats, these devices create intimacy across distance.

This paper examines the practice of retweeting as a way by which participants can be "in a conversation." While retweeting has become a convention inside Twitter, participants embrace it for diverse reasons and using varying styles. Our data and analysis reveal the messiness of retweeting by highlighting how issues of authorship, attribution, and communicative fidelity are negotiated in diverse ways. Using a series of case studies and empirical data, this paper maps out different conversational aspects of retweeting. This paper is currently in review. For citation information, contact danah. We are making it public for commentary/critique. All feedback welcome!!

We study and characterize diurnal patterns in social media data for different urban areas, with the goal of providing context and framing for reasoning about such patterns at different scales. Using one of the largest datasets to date of Twitter content associated with different locations, we examine within-day variability and across-day variability of diurnal keyword patterns for different locations. We show that only a few cities ...

We differentiate between these user types and analyze patterns of sourcing and routing information among them. We describe the symbiotic relationship between media outlets and individuals and the distinct roles particular user types appear to play. Using this analysis, we discuss how Twitter plays a key role in amplifying and spreading timely information across the globe.
