The concept of fragmentation is explored in this book as it applies to arid, pastoral systems throughout the world. Global significance of the world's vast rangelands is large. Arid and semiarid rangelands make up almost 25% of the earth's landscapes and support more than 20 million people whose livelihoods depend on these lands. It is the home of the planet's last remaining megafauna and many other important species. The case is developed that fragmentation arises from different natural, social and economic conditions worldwide but creates similar outcomes for human and natural systems. With information from nine sites around the world the authors examine how fragmentation occurs, the patterns that result, and the consequences of fragmentation for ecosystems and the people who depend on them for their livelihoods.

The idea that multiple personalities can exist within the same body has long captured the Western imagination. From Three Faces of Eve to Sybil, from Pyscho to Raising Caine, from 60 Minutes to Oprah to One Life to Live, we are captivated by the fate of multiples who, divided against themselves, wreak havoc in the lives of others.

Why do we find multiple personality disorder (MPD) so fascinating? Perhaps because each of us is aware of a dividedness within ourselves: we often feel as if we are one person on the job, another with our families, another with our friends and lovers. We may fantasize that these inner discrepancies will someday break free, that within us lie other personalities--genius, lover, criminal--that will take us over and render us strangers to our very selves.

What happens when such a transformation literally occurs, when an alter personality surfaces and commits some heinous deed? What do we do when a Billy Milligan is arrested for a series of rapes and robberies, of which the original personality, Billy, is utterly oblivious? What happens when a Juanita Maxwell, taken over by her alter personality, Wanda, becomes enraged and commits a murder which would horrify Juanita? Who really committed these deeds? Are alter personalities people? Are they centers of consciousness which are akin to people? Mere parts of a deeply divided person? Who should held accountable for the crimes? Which is more appropriate--punishment or treatment?

In Jekyll on Trial, Elyn R. Saks carefully delineates how MPD forces us to re-examine our central concepts of personhood, responsibility, and punishment. Drawing on law, psychiatry, and philosophy, Saks explores the nature of alter personalities, and shows how different conceptualizations bear on criminal responsibility. A wide-ranging and deeply informed book, Jekyll on Trial is must reading for anyone interested in law, criminal justice, psychiatry, or human behavior.

"A thoughtful and thought-provoking exploration of how our criminal justice system should handle an increasingly common mental illness known as multiple personality disorder."
"--Georgetown Law Journal"

"A provocative study of a controversial topic. . . . Saks' analyses are always clear and incisive, comprehensible even when their premises and reasoning are unfamiliar and their conclusions surprising."
"--Psychiatric Services"

"Saks focuses exclusively on multiple personality, a controversial and only recently recognized mental disorder. The philosophical underpinnings that frame the legal questions of culpability, punishment, and competence to stand trial are examined and provide the background for the author's proposals for applicable legal rules. Highly recommended."
"--Library Journal"

With detailed data from nine sites around the world, the authors examine how the so-called 'fragmentation' of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. 'Rangelands' make up a quarter of the world's landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.

Die Funktionentheorie mehrerer komplexer Veranderlichen war in den letzten J ahren in zahlreichen Landern Gegenstand mathematischer Forschung. Die groBe Zahl wissenschaftlicher Untersuchungen auf diesem Gebiete - in wenigen Jahren mehr als vorher in Jahrzehnten macht es den interessierten Gelehrten schwer, sich in der Spezialliteratur zurechtzufinden. Hinzu kommt, daB der Ausgangspunkt und die Vor aussetzungen - vor aHem die unausgesprochenen - bei den verschiede nen Autoren mehr oder minder voneinander abweichen. Das veran laBte den Herausgeber, uns zu einem Bericht tiber das gesamte Gebiet aufzufordern. Nun darf keineswegs tibersehen werden, daB mehrere allgemein ver breitete GesamtdarsteHungen vorliegen. Als altestes Lehrbuch ist hier zu nennen: FORSYTH: Theorie of functions of two variables. Cambridge 1914, sodann der Enzyklopadieartikel von BIEBERBACH, abgeschlossen im Jahre 1922. Wenige Jahre spater (1924, in zweiter Auflage 1929) erschien dann das Werk von OSGOOD: Lehrbuch der Funktionentheorie Band Ill' eine Darstellung, der wohl die meisten von uns ihre EinfUhrung in diesen Stoff verdanken. SchlieBlich hat F. SEVERI 1931 einen Bericht verfaBt, der die rasche Entwicklung der Untersuchungen lebhaft wider spiegelt. Die vorliegende Schrift steht in ihrem Aufbau zwischen einem Lehr buch und einem enzyklopadischen Bericht. Wir waren bestrebt, unter Verarbeitung der neuen Veroffentlichungen eine einheitliche Darstellung zu geben, in der die zugrunde liegenden Voraussetzungen klar herausgearbeitet sind. Bei diesem Ziel konnten wir uns im Aufbau nicht nach historischen Gesichtspunkten richten."

Perhaps the least studied of Hildegard of Bingen's writings, "Solutions to Thirty-Eight Questions" is translated in this volume into English for the first time from the original Latin.
In this work of exegesis, Hildegard (1098-1179) resolves thorny passages of Scripture, theological questions, and two issues in hagiographic texts. "Solutions to Thirty-Eight Questions" joins Hildegard's "Homilies on the Gospels," which were directed to her nuns, as evidence of the seer's exegetical writing as well as her authority as an exegete. The twelfth-century saint wrote in standard genres of exegesis--homilies and "solutiones"--and her interpretations of Scripture were widely sought, including by male audiences.

Fundamentals of Mathematics represents a new kind of mathematical publication. While excellent technical treatises have been written about specialized fields, they provide little help for the nonspecialist; and other books, some of them semipopular in nature, give an overview of mathematics while omitting some necessary details. Fundamentals of Mathematics strikes a unique balance, presenting an irreproachable treatment of specialized fields and at the same time providing a very clear view of their interrelations, a feature of great value to students, instructors, and those who use mathematics in applied and scientific endeavors. Moreover, as noted in a review of the German edition in Mathematical Reviews, the work is "designed to acquaint the student] with modern viewpoints and developments. The articles are well illustrated and supplied with references to the literature, both current and 'classical.'"The outstanding pedagogical quality of this work was made possible only by the unique method by which it was written. There are, in general, two authors for each chapter: one a university researcher, the other a teacher of long experience in the German educational system. (In a few cases, more than two authors have collaborated.) And the whole book has been coordinated in repeated conferences, involving altogether about 150 authors and coordinators.Volume I opens with a section on mathematical foundations. It covers such topics as axiomatization, the concept of an algorithm, proofs, the theory of sets, the theory of relations, Boolean algebra, and antinomies. The closing section, on the real number system and algebra, takes up natural numbers, groups, linear algebra, polynomials, rings and ideals, the theory of numbers, algebraic extensions of a fields, complex numbers and quaternions, lattices, the theory of structure, and Zorn's lemma.Volume II begins with eight chapters on the foundations of geometry, followed by eight others on its analytic treatment. The latter include discussions of affine and Euclidean geometry, algebraic geometry, the Erlanger Program and higher geometry, group theory approaches, differential geometry, convex figures, and aspects of topology.Volume III, on analysis, covers convergence, functions, integral and measure, fundamental concepts of probability theory, alternating differential forms, complex numbers and variables, points at infinity, ordinary and partial differential equations, difference equations and definite integrals, functional analysis, real functions, and analytic number theory. An important concluding chapter examines "The Changing Structure of Modern Mathematics."

Trainees consistently mentioned how helpful it was to have laws relevant to their clinical practice explained in a way that removed the mystery and anxiety associated with lawyers, courts, and judges. Each volume in the series sets forth, in a clear, straightforward, and user-friendly manner, pertinent legislation and court cases, covering why the law was written, what the law says, and how the law affects clinical practice.
