It is different from others in that the author presents the subject in the framework of constraint databases which provide a natural and powerful generalization of relational databases. An important theme running through the text is to show how relational databases can smoothly develop into constraint databses and so relational database users can easily become constraint databaseusers. Switching to constraint databases requires sacrificing none of the benefits of relational databses whilst new advantages may be realised. Peter Revesz begins by discussing data models and how queries may be addressed to these models. From this, he develops the theory of relational and constraint databases including Datalog and the relational calculus. The book then discusses three sample constraint database systems, DISCO, DINGO, and RATHER. Advanced undergraduate students and graduate students in computer science will find this a clear introduction to the subject. Professionals and researchers will appreciate this novel perspective on their subject. 394 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book describes the turbulent political history of Afghanistan from the communist upheaval of the 1970s through to the aftermath of the events of 11 September 2001. It reviews the importance of the region to external powers and explains why warfare and instability have been endemic. The author analyses in detail the birth of the Taliban and the bloody rise to power of fanatic Islamists, including Osama bin Laden, in the power vacuum following the withdrawal of US aid. Looking forward, Nojumi explores the ongoing quest for a third political movement in Afghanistan - an alternative to radical communists or fanatical Islamists and suggests the support that will be neccessary from the international community in order for such a movement to survive. 260 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This extensively documented work explores the historic site of Charles Towne, South Carolina. In his excavation, Stanley South discovered the artifacts from not only the European occupation of the late 1600's but also the earlier remains of Native American settlements. In this work, South criticizes archaeologists who 'discover' artifacts only from the historic period they are focusing on and ignore the evidence from other equally important periods. This excavation and research from one of the foremost historical archaeologists in America is a valuable resource to historical archaeologists, historians and anthropologists, especially those involved in the southeastern United States. 342 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Cancer is one of the major health problems of our time and liver cancer is responsible for over one million deaths per year world-wide, making it the fourth most common cause of death from cancer. Surgical resection of the tumour(s) is the treatment of choice and offers the only chance of prolonged survival. Yet the best attempts are often frustrated by either advanced or co-existent disease that renders the patient non-resectable. This book tackles the many options available to doctors and patients in an attempt to combat this desperate disease. 372 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -At the end of the twentieth century, tourism is the world's largest single industry. Tourism, however, is not only an economic and social phenomenon but can be 'read' in semiotic terms centred around dreams of alternatives to everyday life. The images, which today dominate advertisements for tourist products, had to be constructed and sustained, invented and remoulded over a long historical process. It seems that without this distinctive historical and cultural 'baggage' the remarkable social practice of taking holidays would not have evolved. Even if tourism saw its most spectacular development in the nineteenth and twentieth centuries in terms of the numbers involved, it rests on a cultural foundation inaugurated in the early modern period. The Making of Modern Tourism was a long-term process, deeply rooted in the cultural and intellectual, economic and social history of Britain. 310 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book presents 14 case studies of lobbying campaigns recently directed towards influencing policy and decisions in the EU, and illustrates the effects of recent wideranging change. Treaty revisions have modified the decision-making process and balance of power between the EU institutions. Company lobbying has changed as cross-border mergers have concentrated their activity. The balance of power between member state governments and their devolved regions has shifted, and the regions are increasingly active players. The ability of NGOs to take a recognised part in policy formulation has increased and this change is accelerating. The included cases have been selected to illustrate the range of interest groups who lobby, and to broaden the coverage of lobbying cases in Europe. 331 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book presents a re-examination of classical issues in the relationship between different forms of democratization, civil, political and social, and examines Chile's transition to democracy during the 1990s as a typical case of the modern sequence. It highlights the lasting institutional limits to social democratization in countries that are democratizing in the context of radical market reforms and provides an account of the politics of limiting social deepening in the crucial early years of Chile's transition, including a detailed examination of the influence of local union history and labour relations. 291 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is at least a decade since scientists turned their imaginations to creating new compact, portable test instruments and self-contained test kits that could be used to analyze urine and saliva for alcohol, drugs, and their metabolites. Although the potential applications for such tests at the site of specimen collection, now called 'on-site' or 'point-of-care' testing, range far beyond hospital emergency rooms and law enforcement needs, it was catalyzed by the requirements of workplace drug testing and other drugs-of-abuse testing programs. These programs are now a minor national industry in the United States and in some western European countries, and cover populations as diverse as the military, incarcerated criminals, people suspected of driving under the influence of alcohol and other drugs, all athletes from college to professional ranks, and of course the general employed population, which is monitored for illegal drug use and numbers in the millions. It is not surprising, then, that the need for rapid and precise tests, conducted economically by trained professionals, has become a major goal. Current government approved and peer reviewed laboratory methods for urine analysis serve present needs very well and have become remarkably robust over the past twenty years, but the logistics of testing some moving populations, such as the military, the Coast Guard, workers on off-shore oil platforms, and athletes-perhaps the most mobile of these groups-are unacceptably cumbersome. 270 pp. Englisch.
