This book is intended as a textbook for a first-year Ph. D. course in mathematics for economists and as a reference for graduate students in economics. It provides a self-contained, rigorous treatment of most of the concepts and techniques required to follow the standard first-year theory sequence in micro and macroeconomics. The topics covered include an introduction to analysis in metric spaces, differential calculus, comparative statics, convexity, static optimization, dynamical systems and dynamic optimization. The book includes a large number of applications to standard economic models and over two hundred fully worked-out problems.

This book suggests how high levels of corruption limit investment and growth can lead to ineffective government. Developing countries and those making a transition from socialism are particularly at risk, but corruption is a worldwide phenomenon. Corruption creates economic inefficiencies and inequities, but reforms are possible to reduce the material benefits from payoffs. Corruption is not just an economic problem, however; it is also intertwined with politics. Reform may require changes in both constitutional structures and the underlying relationship of the market and the state. Effective reform cannot occur unless both the international community and domestic political leaders support change. No single 'blueprint' is possible, but the primary goal should be to reduce the gains from paying and receiving bribes, not simply to remove 'bad apples'.

Devoted specifically to modern field theory, this is an indispensable book for graduate students and researchers in theoretical physics. It emphasizes nonperturbative phenomena and supersymmetry, and discusses various phases of gauge theories, extended objects and their quantization, and global supersymmetry from a modern perspective.

Models and Methods in Social Network Analysis presents the most important developments in quantitative models and methods for analyzing social network data that have appeared during the 1990s. Intended as a complement to Wasserman and Faust's Social Network Analysis: Methods and Applications, it is a collection of articles by leading methodologists reviewing advances in their particular areas of network methods. Reviewed are advances in network measurement, network sampling, the analysis of centrality, positional analysis or blockmodelling, the analysis of diffusion through networks, the analysis of affiliation or 'two-mode' networks, the theory of random graphs, dependence graphs, exponential families of random graphs, the analysis of longitudinal network data, graphical techniques for exploring network data, and software for the analysis of social networks.

Ferdinand Tonnies' Gemeinschaft und Gesellschaft (first published in 1887) is a classic of social and political theory, which explores the clash between small-scale neighbourhood-based 'communities' and large-scale competitive market 'societies'. Tonnies considers all aspects of life - political, economic, legal and family; art, religion and culture; the construction of 'selfhood' and 'personhood'; and modes of cognition, language and understanding. Often recognised as one of the founding texts of sociology, Gemeinschaft und Gesellschaft is also a highly significant contribution to European political thought and philosophy, with particular relevance to the legacies of Hobbes and Kant. It is at once a response to modernity, a theoretical exercise in social, political and moral science, and an unusual commentary on the inner character of 'democratic socialism'. This new English rendition will introduce Tonnies' work to a fresh generation of English-speaking readers with interests in social and political theory and the history of European ideas.

Learning sciences is an interdisciplinary field that studies teaching and learning. The sciences of learning include cognitive science, educational psychology, computer science, anthropology, sociology, neuroscience, and other fields. The Cambridge Handbook of the Learning Sciences shows how educators can use the learning sciences to design more effective learning environments - including school classrooms and also informal settings such as science centers or after-school clubs, on-line distance learning, and computer-based tutoring software. The chapters in this handbook each describe exciting new classroom environments, based on the latest science about how children learn. CHLS is a true handbook in that readers can use it to design the schools of the future - schools that will prepare graduates to participate in a global society that is increasingly based on knowledge and innovation.

This is the first full-length biography in more than fifty years of Immanuel Kant, one of the giants among the pantheon of Western philosophers, and one of the most powerful and influential in contemporary philosophy. Taking account of the most recent scholarship, Manfred Kuehn allows the reader to follow the same journey that Kant himself took in emerging as a central figure in modern philosophy. Manfred Kuehn was formerly Professor of Philosophy at Purdue University. A specialist on German philosophy of the period, he is the author of numerous articles and papers on Immanuel Kant.

A mechanism is a mathematical structure that models institutions through which economic activity is guided and coordinated. There are many such institutions; markets are the most familiar ones. Lawmakers, administrators and officers of private companies create institutions in order to achieve desired goals. They seek to do so in ways that economize on the resources needed to operate the institutions, and that provide incentives that induce the required behaviors. This book presents systematic procedures for designing mechanisms that achieve specified performance, and economize on the resources required to operate the mechanism. The systematic design procedures are algorithms for designing informationally efficient mechanisms. Most of the book deals with these procedures of design. When there are finitely many environments to be dealt with, and there is a Nash-implementing mechanism, our algorithms can be used to make that mechanism into an informationally efficient one. Informationally efficient dominant strategy implementation is also studied.

We live in a new age for statistical inference, where modern scientific technology such as microarrays and fMRI machines routinely produce thousands and sometimes millions of parallel data sets, each with its own estimation or testing problem. Doing thousands of problems at once is more than repeated application of classical methods. Taking an empirical Bayes approach, Bradley Efron, inventor of the bootstrap, shows how information accrues across problems in a way that combines Bayesian and frequentist ideas. Estimation, testing and prediction blend in this framework, producing opportunities for new methodologies of increased power. New difficulties also arise, easily leading to flawed inferences. This book takes a careful look at both the promise and pitfalls of large-scale statistical inference, with particular attention to false discovery rates, the most successful of the new statistical techniques. Emphasis is on the inferential ideas underlying technical developments, illustrated using a large number of real examples.

This classic account shows how the fall of Constantinople in May 1453, after a siege of several weeks, came as a bitter shock to Western Christendom. The city's plight had been neglected and negligible help was sent in this crisis. To the Turks, victory not only brought a new imperial capital, but guaranteed that their empire would last. To the Greeks, the conquest meant the end of the civilisation of Byzantium and led to the exodus of scholars stimulating the tremendous expansion of Greek studies in the European Renaissance.

Now available to an English-speaking audience, this book presents a groundbreaking theoretical analysis of memory, identity and culture. It investigates how cultures remember, arguing that human memory exists and is communicated in two ways, namely inter-human interaction and in external systems of notation, such as writing, which can span generations. Dr Assmann defines two theoretical concepts of cultural memory, differentiating between the long-term memory of societies, which can span up to 3,000 years, and communicative memory, which is typically restricted to 80 to 100 years. He applies this theoretical framework to case studies of four specific cultures, illustrating the function contexts and specific achievements, including the state, international law, religion and science. Ultimately, his research demonstrates that memory is not simply a means of retaining information, but rather a force that can shape cultural identity and allow cultures to respond creatively to both daily challenges and catastrophic changes.
