This book arose from a course of lectures given by the first author during the winter term 1977/1978 at the University of Munster (West Germany). The course was primarily addressed to future high school teachers of mathematics; it was not meant as a systematic introduction to number theory but rather as a historically motivated invitation to the subject, designed to interest the audience in number-theoretical questions and developments. This is also the objective of this book, which is certainly not meant to replace any of the existing excellent texts in number theory. Our selection of topics and examples tries to show how, in the historical development, the investigation of obvious or natural questions has led to more and more comprehensive and profound theories, how again and again, surprising connections between seemingly unrelated problems were discovered, and how the introduction of new methods and concepts led to the solution of hitherto unassailable questions. All this means that we do not present the student with polished proofs (which in turn are the fruit of a long historical development); rather, we try to show how these theorems are the necessary consequences of natural questions. Two examples might illustrate our objectives."

This book is the result of a conference on arithmetic geometry, held July 30 through August 10, 1984 at the University of Connecticut at Storrs, the purpose of which was to provide a coherent overview of the subject. This subject has enjoyed a resurgence in popularity due in part to Faltings' proof of Mordell's conjecture. Included are extended versions of almost all of the instructional lectures and, in addition, a translation into English of Faltings' ground-breaking paper. ARITHMETIC GEOMETRY should be of great use to students wishing to enter this field, as well as those already working in it. This revised second printing now includes a comprehensive index.

This book focuses on public health and epidemiologic aspects of cancer, and explores the sources of information concerning the frequency of occurrence of human cancer. It describes statistical methods useful in studying problems arising in the field of cancer and its concurrent development.

This volume is the result of a (mainly) instructional conference on arithmetic geometry, held from July 30 through August 10, 1984 at the University of Connecticut in Storrs. This volume contains expanded versions of almost all the instructional lectures given during the conference. In addition to these expository lectures, this volume contains a translation into English of Falt ings' seminal paper which provided the inspiration for the conference. We thank Professor Faltings for his permission to publish the translation and Edward Shipz who did the translation. We thank all the people who spoke at the Storrs conference, both for helping to make it a successful meeting and enabling us to publish this volume. We would especially like to thank David Rohrlich, who delivered the lectures on height functions (Chapter VI) when the second editor was unavoidably detained. In addition to the editors, Michael Artin and John Tate served on the organizing committee for the conference and much of the success of the conference was due to them-our thanks go to them for their assistance. Finally, the conference was only made possible through generous grants from the Vaughn Foundation and the National Science Foundation."

Illustrated with numerous case studies-many drawn from the author's work as a forensic psychologist-this book identifies 19 myths and misconceptions about youth violence, from ordinary bullying to rampage shootings. It covers controversial topics such as gun control and the effects of entertainment violence on children. The author demonstrates how fear of school violence has resulted in misguided, counterproductive educational policies and practices ranging from boot camps to zero tolerance. He reviews evidence from hundreds of controlled studies showing that school-based school violence prevention programs and mental health services, which are largely effective, are often overlooked in favor of politically popular yet ineffective programs such as school uniforms, Drug Abuse Resistance Education, and Scared Straight. He concludes by reviewing some of his own research on student threat assessment as a more flexible and less punitive alternative to zero tolerance, and presents a wide ranging series of recommendations for improving and expanding the use of school-based violence prevention programs and mental health services for troubled students. Key features include the following: Contrarian Approach-This book identifies and refutes 19 basic misconceptions about trends in youth violence and school safety, and shows how the fear of school violence has been exaggerated through inaccurate statistics, erroneous conclusions about youth violence, and over-emphasis on atypical, sensational cases. Readability-The book translates scientific, evidence-based research into language that educators, parents, law enforcement officers, and policymakers can readily understand and shows what can be done to improve things. Expertise-Dewey Cornell is a forensic psychologist and Professor of Education at the University of Virginia, where he holds an endowed chair in Education. He is Director of the UVA Youth Violence Project and is a faculty associate of the Institute of Law, Psychiatry, and Public Policy. The author of more than 100 publications in psychology and education, he frequently testifies in criminal proceedings and at legislative hearings involving violence prevention efforts. This book is appropriate for courses or seminars dealing wholly or partly with school violence and school safety. It is also an indispensable volume for school administrators and safety officers; local, state, and national policymakers; involved parents; and academic libraries serving these groups.
