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."

This book presents a little-known aspect of America's aircraft development of World War II in emphasizing unique and non-production aircraft or modifications for the purpose of research and experimentation in support of aircraft development, advancing technology, or meeting narrow combat needs. It describes some important areas of American aviation weapons maturation under the pressure of war with emphasis on advanced technology and experimental aircraft configurations. The great value of the work is illumination of little known or minimally documented projects that significantly advanced the science of aeronautics, propulsion, aircraft systems, and ordnance, but did not go into production. Each chapter introduces another topic by examining the state-of-the-art at the beginning of the war, advantages pursued, and results achieved during the conflict. This last is the vehicle to examine the secret modifications or experiments that are little known. Consequently, this is an important single-source for a fascinating and diverse collection of wartime efforts never before brought together under a single cover. The "war stories" are those of military staffs, engineering teams, and test pilots struggling against short schedules and tight resource constraints to push the bounds of technology. These epic and sometimes life-threatening endeavors were as vital as actual combat operations.
