Although conflict is a normal aspect of human life, mass media technologies are changing the dynamics of conflict and shaping strategies for deploying rituals. Rituals can provoke or escalate conflict; they can also mediate it. Media representations have long been instrumental in establishing, maintaining, and challenging political and economic power, as well as in determining the nature of religious practice. This collection of essays emerged from a two-year project based on collaboration between the Faculty of Religious Studies at Radboud University Nijmegen in the Netherlands and the Ritual Dynamics Collaborative Research Center at the University of Heidelberg in Germany. Here, an interdisciplinary team of twenty-four scholars locates, describes, and explores cases in which media-driven rituals or ritually saturated media instigate, disseminate, or escalate conflict. Each chapter, built around global and local examples of ritualized, mediatized conflict, is multi-authored. The book's central question is: "When ritual and media interact (either by the mediatizing of ritual or by the ritualizing of media), how do the patterns of conflict change?"

This book draws a colorful and widespread picture of global affine hypersurface theory up to the most recent state. Moreover, the recent development revealed that affine differential geometry – as differential geometry in general – has an exciting intersection area with other fields of interest, like partial differential equations, global analysis, convex geometry and Riemann surfaces.The second edition of this monograph leads the reader from introductory concepts to recent research. Since the publication of the first edition in 1993 there appeared important new contributions, like the solutions of two different affine Bernstein conjectures, due to Chern and Calabi, respectively. Moreover, a large subclass of hyperbolic affine spheres were classified in recent years, namely the locally strongly convex Blaschke hypersurfaces that have parallel cubic form with respect to the Levi-Civita connection of the Blaschke metric. The authors of this book present such results and new methods of proof.

This volume on pure and applied differential geometry, includes topics on submanifold theory, affine differential geometry and applications of geometry in engineering sciences. The conference was dedicated to the 70th birthday of Prof Katsumi Nomizu. Papers on the scientific work and life of Katsumi Nomizu are also included.

This proceedings consists of papers presented at the international meeting of Differential Geometry and Computer Vision held in Norway and of international meetings on Pure and Applied Differential Geometry held in Belgium. This volume is dedicated to Prof Dr Tom Willmore for his contribution to the development of the domain of differential geometry. Furthermore, it contains a survey on recent developments on affine differential geometry, including a list of publications and a problem list.

This collection of papers on the geometry and topology of submanifolds is taken from meetings held in honour of Professor S.S. Chern. Topics covered include: the classification of timelike Bonnet surfaces; parallel pure spinors on pseudo-Riemannian manifolds; harmonic maps; and more.
