"Visions in Mathematics - Towards 2000" was one of the most remarkable mathematical meetings in recent years. It was held in Tel Aviv from August 25th to September 3rd, 1999, and united some of the leading mathematicians worldwide. The goals of the conference were to discuss the importance, the methods, the past and the future of mathematics as we enter the 21st century and to consider the connection between mathematics and related areas. The aims of the conference are reflected in the present set of survey articles, documenting the state of art and future prospects in many branches of mathematics of current interest. This is the first part of a two-volume set that will serve any research mathematician or advanced student as an overview and guideline through the multifaceted body of mathematical research in the present and near future.

Irregular Connections traces the anthropological study of sex from the eighteenth century to the present, focusing primarily on social and cultural anthropology and the work done by researchers in North America and Great Britain. Andrew P. and Harriet D. Lyons argue that the sexuality of those whom anthropologists studied has been conscripted into Western discourses about sex, including debates about prostitution, homosexuality, divorce, premarital relations, and hierarchies of gender, class, and race. Because sex is the most private of activities and often carries a high emotional charge, it is peculiarly difficult to investigate. At times, such as the late 1920s and the last decade of the twentieth century, sexuality has been a central concern of anthropologists and focal in their theoretical formulations. At other times the study of sexuality has been marginalized. The anthropology of sex has sometimes been one of the main faces that anthropology presented to the public, often causing resentment within the discipline. Andrew P. Lyons is an associate professor of anthropology at Wilfrid Laurier University. Harriet D. Lyons is an associate professor of anthropology at the University of Waterloo.

Clusters of workstations/PCs connected by o?-the-shelf networks have become popular as a platform for cost-e?ective parallel computing. Hardware and so- ware technological advances have made this network-based parallel computing platform feasible. A large number of research groups from academia and industry are working to enhance the capabilities of such a platform, thereby improving its cost-e?ectiveness and usability. These developments are facilitating the mig- tion of many existing applications as well as the development of new applications on this platform. Continuing in the tradition of the two previously successful workshops, this 3rd Workshop on Communication, Architecture and Applications for Netwo- based Parallel Computing (CANPC’99) has brought together researchers and practitioners working in architecture, system software, applications and perf- mance evaluation to discuss state-of-the-art solutions for network-based parallel computing systems. This workshop has become an excellent forum for timely dissemination of ideas and healthy interaction on topics at the cutting edge in cluster computing technology. Each submitted paper underwent a rigorous review process, and was assigned to at least 3 reviewers, including at least 2 program committee members. Each paper received at least 2 reviews, most received 3 and some even had 4 reviews.

"...A nice feature of the book [is] that at various points the authors provide examples, or rather counterexamples, that clearly show what can go wrong...This is a nicely-written book [that] studies algebraic differential modules in several variables." --Mathematical Reviews
