Concurrent constraint programming (ccp) is a recent development in programming language design. Its central contribution is the notion of partial information provided by a shared constraint store. This constraint store serves as a communication medium between concurrent threads of control and as a vehicle for their synchronization. Objects for Concurrent Constraint Programming analyzes the possibility of supporting object-oriented programming in ccp. Starting from established approaches, the book covers various object models and discusses their properties. Small Oz, a sublanguage of the ccp language Oz, is used as a model language for this analysis. This book presents a general-purpose object system for Small Oz and describes its implementation and expressivity for concurrent computation. Objects for Concurrent Constraint Programming is written for programming language researchers with an interest in programming language aspects of concurrency, object-oriented programming, or constraint programming. Programming language implementors will benefit from the rigorous treatment of the efficient implementation of Small Oz. Oz programmers will get a first-hand view of the design decisions that lie behind the Oz object system.

Regional issues are increasingly debated across the social sciences. In an age of globalization, the region has come to matter perhaps more than before. In business, companies orient themselves to engage in regional environments to build capabilities and create critical mass in their vicinity. In the world of policy, almost one-third of the EU budget is spent on regional policy. Yet in spite of this the differences between regions that do well and those that do not are increasing in both Europe and the United States. In recent years, evolutionary economic geography has done much to create a framework to inform regional policy and academic work. Using its insights, Martin Henning explores why economic growth and transformation is an essentially regionally based and spatially dependent process. The book offers an accessible introduction to the core ideas involved in understanding the dynamics of regional economies and draws on case studies to illuminate these ideas in practice.
