This third volume in Advances in Environment, Behavior, and Design fol lows the conceptual framework adopted in the previous two volumes (see the Preface to Volume 1, 1987). It is organized into five sections advances in theory, advances in place, user group, and sociobehavioral research, and advances in research utilization. The authors of this volume represent a wide spectrum of the multi disciplinary environment-behavior and design field including architec ture, environmental psychology, facility management, geography, human factors, sociology, and urban design. The volume offers interna tional perspectives from North America (Carole Despres from Canada, several authors from the U.S.), Europe (Martin Krampen from Germany, Martin Symes from England), and New Zealand (David Kernohan). More so than any of the previous volumes, they are drawn from both academia and professional practice. While there continues to be a continuity in format in the series, we are actively exploring new directions that are on the cutting edges of the field and bode well for a more integrated future. This volume will fur ther develop the themes of design and professional practice to comple ment the earlier emphases on theory, research, and methods.

This second volume in the Advances in Environment, Behavior, and Design series follows the pattern of Volume 1. It is organized into six sections user group research, consisting of advances in theory, place research, sociobehavioral research, research and design methods, and research utilization. The authors of the chapters in this volume represent a range of disciplines, including architecture, geography, psychology, social ecology, and urban planning. They also offer international perspectives: Tommy Garling from Sweden, Graeme Hardie from South Africa (re cently relocated to North Carolina), Gerhard Kaminski from the Federal Republic of Germany, and Roderick Lawrence from Switzerland (for merly from Australia). Although most chapters address topics or issues that are likely to be familiar to readers (environmental perception and cognition, facility pro gramming, and environmental evaluation), four chapters address what the editors perceive to be new topics for environment, behavior, and design research. Herbert Schroeder reports on advances in research on urban for estry. For most of us the term forest probably conjures up visions of dense woodlands in rural or wild settings. Nevertheless, in many parts of the country, urban areas have higher densities of tree coverage than can be found in surrounding rural landscapes. Schroeder reviews re search that addresses the perceived and actual benefits and costs associ ated with these urban forests.

The papers comprising this second volume of Human Behavior and the Environment represent, as do their predecessors, a cross section of current work in the broad area of problems dealing with interrelation ships between the physical environment and human behavior, at both the individual and the aggregate levels. Considering the two volumes as a unit, we have included papers covering a broad spectrum of problems ranging from the theoretical to the applied, and from the disciplinary-based to the interdisciplinary and professional. Approxi mately half of the papers are written by psychologists, with the remainder coming, in part, from such other disciplines as sociology, geography, and from such diverse applied and professional fields as natural recreation, landscape architecture, urban planning, and opera tions research. The volumes thus provide an overview of work on current topical problems. Yet, as the field is developing, specialization is inevitably increasing apace, and the editors as well as the publisher have become convinced of the desirability for futu're volumes in this series to be organized along topical lines, with successive volumes devoted to different aspects of this rather sprawling field. Thus, Volume 3, currently in the planning stage, will be devoted exclusively to the interaction of children with the physical environment, considered from diverse viewpoints, again including authors from diverse fields of specialization.
