An exploration of the geography by which measles has repeatedly passed through a series of communities in Iceland during the 20th century. Demonstrates the general principles which underlie person-to-person spatial diffusion processes.

In this concise, clear introduction, the authors describe the theory of spatial diffusion, its method of measurement and many of its applications. The seminal work of Torsten Hagerstrand, who introduced the original spatial model of diffusion, is outlined. The authors then summarise the developments that have been made to Hagerstrand's formulation, and make suggestions for future research.

This title provides a broad overview of the different types of models used in advanced spatial analysis. The models concern spatial organization, location factors and spatial interaction patterns from both static and dynamic perspectives. Each chapter gives a broad overview of the subject, covering both theoretical developments and practical applications. The advantages of an interdisciplinary approach are illustrated in the way that the viewpoint of each of the individual disciplines are brought together when considering questions relevant to spatial analysis. The authors of the chapters come from a range of different disciplines (geography, economy, hydrology, ecology, etc.) and are specialists in their field. They use a range of methods and modeling tools developed in mathematics, statistics, artificial intelligence and physics.

In addition to presenting the latest work in the field, Artificial Life V includes a retrospective and prospective look at both artificial and natural life with the aim of refining the methods and approaches discovered so far into viable, practical tools for the pursuit of science and engineering goals. May 16-18, 1996 · Nara, Japan Despite all the successes in computer engineering, adaptive computation, bottom-up AI, and robotics, Artificial Life must not become simply a one-way bridge, borrowing biological principles to enhance our engineering efforts in the construction of life-as-it-could-be. We must ensure that we give back to biology in kind, by developing tools and methods that will be of real value in the effort to understand life-as-it-is. Artificial Life V marks a decade since Christopher Langton organized the first workshop on artificial life--a decade characterized by the exploration of new possibilities and techniques as researchers have sought to understand, through synthetic experiments, the organizing principles underlying the dynamics (usually the nonlinear dynamics) of living systems. In addition to presenting the latest work in the field, Artificial Life V includes a retrospective and prospective look at both artificial and natural life with the aim of refining the methods and approaches discovered so far into viable, practical tools for the pursuit of science and engineering goals.

Spatial Modeling in GIS and R for Earth and Environmental Sciences offers an integrated approach to spatial modelling using both GIS and R. Given the importance of Geographical Information Systems and geostatistics across a variety of applications in Earth and Environmental Science, a clear link between GIS and open source software is essential for the study of spatial objects or phenomena that occur in the real world and facilitate problem-solving. Organized into clear sections on applications and using case studies, the book helps researchers to more quickly understand GIS data and formulate more complex conclusions. The book is the first reference to provide methods and applications for combining the use of R and GIS in modeling spatial processes. It is an essential tool for students and researchers in earth and environmental science, especially those looking to better utilize GIS and spatial modeling. - Offers a clear, interdisciplinary guide to serve researchers in a variety of fields, including hazards, land surveying, remote sensing, cartography, geophysics, geology, natural resources, environment and geography - Provides an overview, methods and case studies for each application - Expresses concepts and methods at an appropriate level for both students and new users to learn by example

Colonial governments, institutions and companies recognised that in many ways the effective operation of the Empire depended upon sexual arrangements. For example, nuclear families serving agricultural colonization, and prostitutes working for single men who powered armies and plantations, mines and bureaucracies. For this reason they devised elaborate systems of sexual governance, such as attending to marriage and the family. However, they also devoted disproportionate energy to marking and policing the sexual margins. In Sex, Politics and Empire, Richard Phillips investigates controversies surrounding prostitution, homosexuality and the age of consent in the British Empire, and revolutionises our notions about the importance of sex as a nexus of imperial power relations.

In the past decade there has been growing recognition that economic development is not mainly exogenously determined but, to a large extent, is a transformation process induced and governed by economic actors who respond to competitive, institutional and political challenge. This 'challenge and response' model is increasingly accepted as a valid analytical framework in modem growth theory and also explains the popularity of endogenous growth approaches to technological innovation issues. However, a major and as yet largely under-researched topic is the question of the diffusion and adoption of new technological changes in the context of space-time dynamics. This diffusion and adoption pattern has obviously clear spatial and temporal variations connected with behavioural responses which may vary over time and different locations. This means that a closer analysis of spatio-temporal opportunities and impediments is necessary in order to fully map the complex interactions of technology and economy in space and time. This volume sets out to bring together a collection of original contributions commissioned by the editors to highlight the spatio-temporal patterns and backgrounds of the diffusion and adoption of new technologies. Some are in the nature of a survey, others.have a modelling background and again others are case studies. The contributions originate from different countries and different disciplines. This book is complementary to a previously published volume on technological innovation, Technological Change, Economic Development and Space, edited by C.S. Bertuglia, M.M. Fischer and G. Preto, and also published by Springer-Verlag (1995).
