Taschenbuch. Condizione: Neu. Neuware -Since World War I scholars and practitioners alike have addressed themselves to defining and assessing the 'new diplomacy,' which the British diplomatist Harold Nicolson has branded the 'American method.' He distinguishes contemporary practice from earlier forms of diplomacy which, in The Evolution of Diplomatic Method (1954), on the basis of historical orientation, he designates the Greek, Roman, Italian, and French 'systems' of diplo macy, in this order. Intensified multilaterial, as differentiated from bilateral, diplomacy - or what Lord Maurice Hankey treats as Diplomacy by Con ference (1946) - has become one of the principal qualities characterizing twentieth century diplomatic usage. 'Conference diplomacy,' in turn, consists of both ad hoc and regularized components. The latter, sometimes designated 'parliamentary diplomacy,' is essentially a form of institutionalized conferencing permeating the func tioning of permanent mechanisms called international organizations. Within them member states pursue national and collective interests and espouse national policies, confer and negotiate respecting mutual problems, engage in forensic and often public exposition, and reduce decision making, but usually only ostensibly, to a formalized voting process.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 272 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -lowe the present book to the encouragement and guidance of my friends, for which I am moSll: indebted to them. This applies in the first place to Dr. P. Middelkoop, who worked in Timor for more than thirty years as a missionary and bible translator. My gratitude for all the help he has given can hardly be expressed in words, and I can do no more than simply say that this book is to a large extent also his book - the writing of it could not have been accomplished without his valued assistance. He has given up many an evening to the an swering of my countless questions with his inexhaustible knowledge of the language and culture of the Atoni. am also deeply grateful to Professor L. Onvlee, who acted as my I supervisor during the preparation of the D1.lII:ch version of this book for submission as a doctoral thesis (H et Politieke Systeem van de A toni van Timor, Driebergen, 1966, 278 pp.). But for the many stimulating conversations I was able to enjoy with him I would never have acquired the approach to our subject which lies at the basis of this book, namely that the essential point is the study of man in his culture, and that even in the analysis of one particular aspect of a cul.ture we are dealing with the culture as a whole and with man as the bearer of that cuLture.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 560 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The present attempt to introduce the general philosophical reader to the Phenomenological Movement by way of its history has itself a history which is pertinent to its objective. It may suitably be opened by the following excerpts from a review which Herbert W. Schneider of Columbia University, the Head of the Division for Internc. . tional Cultural Cooperation, Department of Cultural Activities of Unesco from 1953 to 56, wrote in 1950 from France: The influence of Husser! has revolutionized continental philosophies, not because his philosophy has become dominant, but because any philosophy now seeks to accommodate itself to, and express itself in, phenomenological method. It is the sine qua non of critical respectability. In America, on the contrary, phenomenology is in its infancy. The aver age American student of philosophy, when he picks up a recent volume of philosophy published on the continent of Europe, must first learn the 'tricks' of the phenomenological trade and then translate as best he can the real import of what is said into the kind of analysis with which he is familiar. . . . . . . No doubt, American education will gradually take account of the spread of phenomenological method and terminology, but until it does, American readers of European philosophy have a severe handicap; and this applies not only to existentialism but to almost all current philosophicalliterature.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 456 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -In znodern pharznacognosy chemical and physical-cheznical methods are being used znore and more for the investigation of medicinal plants. This important fact and the increasing involvement of chemistry, biocheznistry and botany in pllarmaceuti cal, znedicinal and general biological questions usher in a new epoch in the disco very of medicinal substances and the development of drugs derived from the plant kingdom. One of the guiding ideas of the first 'Syznposiuzn on Pharznacognosy and Phytocheznistry' was to promote these developments, to provide an additional sti znulus and to establish a basis for better coordination and cooperation. The organizers intended that most of the modern branches of research into natural products should be represented, including analysis, structural chemistry, chemi cal synthesis and biosynthesis, as well as pharmacology. Since the plenary lectures also reflect the present level of knowledge in some iznportant areas of natural products research, this volume will constitute an important source of information for an scientists interested in natural substances. Its usefulness is much enhanced by the fact, that the voluzne will appear only four znonths after the Symposiuzn, thanks to the kind assistance of Dr. K. F. Springer of Springer-Verlag. The organizers extend cordial thanks to an the participants for their interesting contributions and herewith invite them to attend the second Syznposium in 1973. We want to express our special thanks to Miss Seitz and Miss Hagendorn for their rapid and conscientious preparation of the manuscripts for offset-printing.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 396 pp. Englisch.

Buch. Condizione: Neu. Neuware -Now a common tool and object of study, stacks were introduced in this book as a framework for the study of non-abelian cohomology classes in degrees 1 and 2 on an arbitrary topos. The book shows that these cohomology classes can be represented by geometric objects called torsors and gerbes, and provides a detailed study of their basic properties. Since their introduction in this book, gerbes have become a widespread tool in geometry and topology. A timeless classic, this French language book remains to this day a key reference for fibred categories, stacks, torsors, gerbes and topos.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 484 pp. Französisch.

Taschenbuch. Condizione: Neu. Neuware -Der vorliegende zweite Tell behandelt die Statik der deformierbaren Korper und damit zugleich die Grundlagen der Festigkeitslehre. Der Inhalt entspricht im wesentlichen der Mechanikvorlesung fiir die Stu dierenden des zweiten Semesters an den Technischen Universitaten. Wie beim ersten Teil war das didaktische Ziel eine systematische und klar verstandliche Darstellung, bereichert durch aktuelle und instruk tive Anwendungsbeispiele. Angesichts der Erfolge der wissenschaftlich technischen Forschung und des dadurch ermoglichten rasanten tech nischen Fortschrittes, der den Ingenieur der Zukunft vor Aufgaben ungeahnten AusmaBes stellen wird, erschien eine vertiefte Darstellung der Grundlagen unumganglich. Dennoch wurde darauf geachtet, daB die mathematischen Anforderungen nicht iiber das Niveau hinausgehen. das in den gleichzeitig laufenden Mathematikvorlesungen jeweils ge rade erreicht ist. Die fiir Tensoren bereits im ersten Tell eingefiihrte Indexschreibweise setzt - trotz ihrer groBen Tragweite - ohnehin nur die Grundrechnungsarten und die einfachsten projektiven Regeln voraus. Sie findet nunmehr eine besonders instruktive Anwendung bei der Beschreibung des Vorganges der inneren Kraftiibertragung und Formanderung, die zur Einfiihrung der Spannungs- und Verzerrungs tensoren fiihrt.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 348 pp. Deutsch.

Taschenbuch. Condizione: Neu. Neuware -In jüngerer Zeit sind eine Reihe theoretischer Arbeiten ver öffentlicht worden, in denen die Auswirkung nicht-konservativer Kräfte auf die Stabilität von mechanischen Systemen untersucht wurde. In der vorliegenden als Dissertation ausgearbeiteten Studie (Referent: Prof. Dr. eh. Wehrli, Korreferent Prof. Dr. B. Thürlimann) untersucht Herr Pozzi diesen Problemkreis im Hinblick auf die Stabilität von Bauwerken. Zur Beruhigung der Bauingenieure stellt er abschliessend fest, dass zur Beurteilung der Stabilität von Bauwerken das bisher allgemein übliche statische Kriterium meistens genügt. Nur in Fällen, wo Kräfte vorhanden sind, die dem System Energie zuführen, muss das kinetische Kriterium in Betracht gezogen werden. Für diese Systeme wurden Bedingungen entwickelt, aus denen untere Schranken für die kleinste kritische Last auf ein fache Art berechnet werden können. Sind die nicht-konserva tiven Kräfte relativ klein gegenüber den Schwerelasten, so ist eine kinetische Analyse nur notwendig, wenn die Dämpfung des Systems schwach ist.

Es zeigte sich ferner, daB Fragen aus sehr verschie den en Teilen der numerischen Mathematik sich dem Problemkreis der Optimierung unterordnen; so fiihren viele Typen von Anfangswert-und Randwertaufgaben bei gewohnlichen und partiellen Differentialgleichun gen, Approximationsaufgaben, spieltheoretische Fragen und vieles andere auf Optimierungsaufgaben. Der wachsenden Bedeutung dieses Gebietes entsprechend, sind in letzter Zeit eine Anzahl Lehrbiicher erschienen, so daB man nach der Berechtigung eines weiteren Buches fragen wird. Nun beschaftigen sich die meisten der vorhandenen Lehrbiicher mit Teilgebie ten, z. B. mit linearer oder mit nichtlinearer Optimierung (oder 'Pro gramming'), mit Spieltheorie usw. So war es die Absicht dieses Buches, einen gewissen Oberblick tiber das gesamte Gebiet zu vermitteln und dabei besonders auch die Zusammenhange und Querverbindungen zwi schen den verschiedenen oben bereits genannten Gebieten darzustellen. Da wir auBerdem den Eindruck haben, daB selbst in Mathematiker Kreisen diese neuen Gebiete, z. B. die schon en allgemeinen Satze tiber Systeme von Gleichungen und Ungleichungen, noch nicht allgemein bekannt geworden sind, wollten wir mit diesem Buche eine allgemeine, leichtfaBliche und auch dem Praktiker verstandliche Einftihrung in dieses vielgestaltige Gebiet mit vollstandigen Herleitungen geben, ohne jedoch allzusehr auf die Einzelheiten der rechnerischen Durchftihrung einzu gehen. Auch konnten verschiedene weitergehende Fragen, wie z. B. die Theorie der optimalen Prozesse (nach PONTRJAGIN) und die dynamische Optimierung (nach BELLMAN) nicht besprochen werden. Das Buch ist aus verschiedenen Vorlesungen der Verfasser an der Universitat Hamburg entstanden.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Deutsch.
