The goal of the Joint Conference of ICPCA7 and SWS4 is to further explore both theoretical and practical issues in and around the emerging computing paradigms, e.g. pervasive collaboration, collaborative business, networked societies. We encourage theoretical, methodological, empirical, and applications papers. The proceedings of this conference will be published in Springer's Lecture Notes in Computer Science series (LNCS). Deadline for Submission: June 30, 2012. For more information, please visit: http://uais.lzu.edu.cn/icpca-sws2012/index.html
