I just filed the final project report for my Career Award yesterday, so I’d like to give my personal thanks to the good folks of the Human-Centered Computing group at the Computing, Information Systems & Engineering (CISE) Directorate of the National Science Foundation. The materials in my book and my ongoing research agenda are possible thanks to their support under Grant No. IIS-0347595. (Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation.) Many thanks, NSF!
