This collection of essays proposes that climate change means serious peril. Our argument, however, is not about the science per se. It is about us, our deep and more recent history, and how we arrived at this calamitous impasse. With contributions from academic activists and independent researchers, History at the End of the World challenges advocates of 'business as usual' to think again. But in its wide-ranging assessment of how we transcend the current crisis, it also proposes that the human past could be our most powerful resource in the struggle for survival. Our approaches begin from archaeology, literature, religion, psychology, sociology, philosophy of science, engineering and sustainable development, as well as 'straight' history. Mark Levene is Reader in Comparative History at the University of Southampton, Rob Johnson is a historian at All Souls College, Oxford, and Penny Roberts is Associate Professor in History at the University of Warwick.

Database theory is now in a mature state, and this book addresses important extensions of the relational database model such as deductive, temporal and object-oriented databases. It provides an overview of database modelling with the Entity-Relationship (ER) model and the relational model providing the pivot on which the material revolves. The main body of the book focuses on the primary achievements of relational database theory, including query languages, integrity constraints, database design, comput able queries and concurrency control. The most important extensions of the relational model are covered in separate chapters. This book will be useful to third year computer science undergraduates and postgraduates studying database theory, and will also be of interest to researchers and database practitioners who would like to know more about the ideas underlying relational dat abase management systems and the problems that confront database researchers.

The role of massacre in history has been given little focused attention either by historians or academics in related fields. This is surprising as its prevalence and persistence surely demands that it should be a subject of serious and systematic exploration. What exactly is a massacre? When - and why - does it happen?
