Over the past five years, through a continually increasing wave of activity in the physics community, supergravity has come to be regarded as one of the most promising ways of unifying gravity with other particle interaction as a finite gauge theory to explain the spectrum of elementary particles. Concurrently im portant mathematical works on the arena of supergravity has taken place, starting with Kostant's theory of graded manifolds and continuing with Batchelor's work linking this with the superspace formalism. There remains, however, a gap between the mathematical and physical approaches expressed by such unanswered questions as, does there exist a superspace having all the properties that physicists require of it? Does it make sense to perform path integral in such a space? It is hoped that these proceedings will begin a dialogue between mathematicians and physicists on such questions as the plan of renormalisation in supergravity. The contributors to the proceedings consist both of mathe maticians and relativists who bring their experience in differen tial geometry, classical gravitation and algebra and also quantum field theorists specialized in supersymmetry and supergravity. One of the most important problems associated with super symmetry is its relationship to the elementary particle spectrum."

As the editors of the first book on the squirrel monkey prophesied in 1968, * there has been an incredible expansion in primate research during the past 16 years. Their projection that the squirrel monkey would play an increasingly important role in this research effort has also come to be true during the ensuing years. One inadvertent result of the rapid growth, however, is that it has become more and more difficult for investigators to keep track of new information, both in their own disciplines and in related fields. For scientists who study and use the squirrel monkey in research, this problem is particularly pronounced, because articles are often published in specialized and disparate journals. We felt that a new synthesis of the vast amount of information on Saimiri would resolve this problem and would provide an extremely valuable com panion volume to the first book. The idea grew out of a small symposium held at the IX Congress of the International Primatological Society in Atlanta, Geor gia, during August, 1982. Following the format of The Squirrel Monkey, ad ditional authors were invited to discuss advances in areas which had experi enced exceptional growth or to review basic information that would be of practical value to future researchers. Even with focused topics and synthetic reviews, the wealth of new data resulted in many long manuscripts. In response to the continuing problems with Saimiri nomenclature, Richard Thorington has provided us with a definitive statement on squirrel monkey taxonomy."

From August 21 through August 27, 1989 the Nato Advanced Research Workshop Probabilistic Methods in Quantum Field Theory and Quantum Gravity" was held at l'Institut d'Etudes Scientifiques, Cargese, France. This publication is the Proceedings of this workshop. The purpose of the workshop was to bring together a group of scientists who have been at the forefront of the development of probabilistic methods in Quantum Field Theory and Quantum Gravity. The original thought was to put emphasis on the introduction of stochastic processes in the understanding of Euclidean Quantum Field Theory, with also some discussion of recent progress in the field of stochastic numerical methods. During the final preparation of the meeting we broadened the scope to include all those Euclidean Quantum Field Theory descriptions that make direct reference to concepts from probability theory and statistical mechanics. Several of the main contributions centered around a more rigorous discussion of stochastic processes for the formulation of Euclidean Quantum Field Theory. These rather stringent mathematical approaches were contrasted with the more heuristic stochastic quantization scheme developed in 1981 by Parisi and Wu: Stochastic quan tization, its intrinsic BRST -structure and stochastic regularization appeared in many disguises and in connection with several different problems throughout the workshop.

The first international conference on. relativity physics and parallel computing took place February 24-28, 1986, at the International Institute of Theoretical Physics at Utah State University in Logan, Utah. Before proceeding to summarize some of the main points of the conference I would like to make a few remarks about the goals of the International Institute of Theoretical Physics. The Institute undertakes frontier research in both pure and applied physics and is housed in the new physics building at Utah State University. The applied research is in solar energy and optical parallel computing. We are in the midst of building four very efficient solar collectors and, in the very near future, parts of an optical parallel computer in the Institute. The pure research is concerned with relativity physics, particle physics, condensed matter physics, quantum systems, etc. On the macroscop ic level, we are concerned with possible experimental tests of Einstein's General Relativity. On the microscopic level, we are interested in the unification of gravitation with the other interactions. In addition to research, the International Institute sponsors visiting scientists and en courages collaborations, etc."

How are we to understand the complex forces that shape human behavior? A variety of diverse perspectives, drawing upon studies of human behavioral ontogeny, as well as humanity's evolutionary heri tage, seem to provide the best likelihood of success. It is in the attempt to synthesize such potentially disparate approaches to human devel opment into an integrated whole that we undertake this series on the Genesis of Behavior. In many respects, the incredible burgeoning of research in child development over the last decade or two seems like a thousand lines of inquiry spreading outward in an incoherent starburst of effort. The need exists to provide, on an ongoing basis, an arena of discourse within which the threads of continuity between those diverse lines of research on human development can be woven into a fabric of meaning and understanding. Scientists, scholars, and those who attempt to translate their efforts into the practical realities of the care and guidance of infants and children are the audience that we seek to reach. Each requires the opportunity to see-to the degree that our knowledge in given areas permits-various aspects of development in a coherent, integrated fashion. It is hoped that this series, which will bring together research on infant biology, developing infant capacities, animal models, the impact of social, cultural, and familial forces on development, and the distorted products of such forces under certain circumstances, will serve these important social and scientific needs."
