• Sommario/riassunto: The explosion of data arising from rapid advances in communication, sensing and computational power has concentrated research effort on more advanced techniques for the representation, processing, analysis and interpretation of data sets. In view of these exciting developments, the program "Mathematics and Computation in Imaging Science and Information Processing" was held at the Institute for Mathematical Sciences, National University of Singapore, from July to December 2003 and in August 2004 to promote and facilitate multidisciplinary research in the area. As part of the program, a series

• Sommario/riassunto: Global Secularisms addresses the state of and prospects for secularism globally. Drawing from multiple fields, it brings together theoretical discussion and empirical case studies that illustrate "on-the-ground," extant secularisms as they interact with various religious, political, social, and economic contexts. Its point of departure is the fact that secularism is plural and that various secularisms have developed in various contexts and from various traditions around the world. Secularism takes on different social meanings and political valences wherever it is expressed. The essays collected here provide numerous points of contact between empirical case studies and theoretical reflection. This multiplicity informs and challenges the conceptual theorization of secularism as a universal doctrine. Analyses of different regions enrich our understanding of the meanings of secularism, providing comparative range to our notions of secularity. Theoretical treatments help to inform our understanding of secularism in context, enabling readers to discern what is at stake in the various regional expressions of secularity globally. While the bulk of the essays are case-based research, the current thinking of leading theorists and scholars is also included.
