William Norton – författare

An innovative contribution to the literature of cultural geography, this book explores the evolution of landscape--both material and symbolic--from the standpoint of the populations, cultures, and human decision-making processes that shape and give it meaning. Focusing on evolution, behavior, symbolism, and ecology, Norton offers a critique of the literature of cultural and social geography and articulates a framework of central issues that connect a wide range of theoretical approaches.In the first four chapters, Norton gives detailed consideration to both traditional and contemporary literature and methodologies and to the links between cultural geography and other social science concepts and analytical methods. The remaining chapters are concerned with the causes and consequences of cultural landscape evolution and the variables affecting it, including language, religion, politics, society, economy, and the physical environment. In addressing these areas of cultural geography, Norton promotes an approach that integrates the contributions of geography with those of anthropology, sociology, psychology, and history. His analysis provides a useful synthesis of the conceptual and empirical content of cultural geography and suggests promising new directions for research in the field. Norton's work will prove a valuable classroom and library resource for students and scholars in cultural and social geography and related areas of sociology and anthropology.

This series has addressed a constituency of scientists possessing biochemical background with the goal of providing them with specialized reviews of neu­ robiological interest. Since its initiation, neurochemistry and neuroscience have come of age, and the editors initiate with this volume the concept of a central theme. It is planned that each subsequent volume will also be topical. We note with sadness the passing of Dr. Henry Mahler who served as an advisory editor since the initiation of this series. He played a major role in building the bridge between biochemistry and neurochemistry and will be missed. Weare pleased to welcome two new editors, Drs. William Norton and Bruce McEwen. B. W. Agranoff M. H. Aprison vii FOREWORD Oligodendroglia constitute one of the three principal cell types of the central nervous system. These cells, together with their elaborated membranes, account for at least 25 percent of the dry mass of an adult rat brain and an even greater percentage of the central nervous system of larger animals.
