Mathematical models have long been used by geographers and regional scientists to explore the working of urban and regional systems, via a system where the equilibrium point changes slowly and smoothly as the parameters change slowly and smoothly. However, this all changed with the advent of catastrophe theory and bifurcation, which enabled the development of models where a quite sudden change in the position of the equilibrium point results from a slow, small, smooth change in one or more parameters. First published in 1981, this reissue of Professor Wilson’s classic study outlines the implications of these mathematical models for geography and regional science, by way of a survey of contemporary applications.

This edited collection, first published in 1987, provides a comparative analysis of different approaches to urban modelling, and lays the foundations for the possibility of integration and a more unified field. The first part contextualises the development of the field of urban systems modelling, focusing on the variety of approaches and possible implications of this on the future of research and methodology. Next, the editors consider economic and ‘non-economic’ approaches, followed by an analysis of spatial-interaction-based approaches. Providing an overview to the field and research literature, the overarching argument is that there should be an integrated methodological approach to urban system modelling.

Geography and Geographers continues to be the most comprehensive and up-to-date overview of human geography available. It provides a survey of the major debates, key thinkers and schools of thought in the English-speaking world, setting them within the context of economic, social, cultural, political and intellectual changes. It is essential reading for all undergraduate geography students. It draws on a wide reading of the geographical literature and addresses the ways geography and its history are understood and the debates among geographers regarding what the discipline should study and how. This extensively updated seventh edition offers a thoroughly contemporary perspective on human geography for new and more experienced students alike.

Originally published in 1990, this work analyses the use of contemporary computer models to simulate urban systems. The work deals with the two significant traditions of model-building: firstly the building of integrated models following the seminal research of Lowry first published in 1964, but with relatively simple submodels; and secondly, intensive research on particular submodels with a variety of techniques. This volume constructs a model-building exercise which integrates the two traditions: an integrated model (in a modular form with alternative components) using the most advanced submodels. The book concludes with a presentation of an example of an operational model of this type.

Urban and Regional Agriculture: Building Resilient Food Systems explores the sustainable integration of food provision, distribution and consumption through urban farms, agricultural systems, user communities and structural facilities designed to optimize food production and consumption. The book addresses the fundamental and pressing challenges of urban planning problems, waste minimization, food sourcing, access and equity issues, and multiple land use optimization. Sections cover the need and opportunities of urban agriculture, discuss tradition and transition, space and regulatory topics, explore the range of urban agriculture options (aquaculture to urban permaculture), discuss support structures and constructs of physically creating urban agricultural areas, and much more. Edited and authored by leading experts in the field, this volume will be valuable for those working to address issues of food security in urban environments. - Integrates agriculture and urban settings to improve food security - Examines relevant considerations, from development to the regulation of food system architectures - Provides regionally specific considerations to guide effective and efficient implementation

This Handbook of Cities and Networks provides a cutting-edge overview of research on how economic, social and transportation networks affect processes both in and between cities. Exploring the ways in which cities connect and intertwine, it offers a varied set of collaborations, highlighting different theoretical, historical and methodological perspectives.

Alan Wilson surveys the range of applications currently devised that have been developed from new advances in mathematics enabling the development of models where sudden changes in equilibrium can be accounted for.

A highlight of Volume 18 is two developmental studies that attempt to situation psychoanalysis within the landscape of contemporary science: R. Galatzer-Levy and B. Cohler's examination of the developmental psychology of the self and F. Levin's consideration of psychological development and the changing organization of the Brain. Clinical studies focus on analytic stalemate (J.G. Maguire); the dream screen transference (D. Edelstein); and varieties of therapeutic alliance (B. Brandchaft and R. Stolorow).

What is the difference between a wink and a blink? The answer is important not only to philosophers of mind, for significant moral and legal consequences rest on the distinction between voluntary and involuntary behavior. However, "action theory"—the branch of philosophy that has traditionally articulated the boundaries between action and non-action, and between voluntary and involuntary behavior—has been unable to account for the difference. Alicia Juarrero argues that a mistaken, 350-year-old model of cause and explanation—one that takes all causes to be of the push-pull, efficient cause sort, and all explanation to be prooflike—underlies contemporary theories of action. Juarrero then proposes a new framework for conceptualizing causes based on complex adaptive systems. Thinking of causes as dynamical constraints makes bottom-up and top-down causal relations, including those involving intentional causes, suddenly tractable. A different logic for explaining actions—as historical narrative, not inference—follows if one adopts this novel approach to long-standing questions of action and responsibility.
