While magnetic fields permeate the universe on all scales, the present book is dedicated to their investigation on the largest scales and affords a balanced account of both theoretical and observational aspects. Written as a set of advanced lectures and tutorial reviews that lead up to the forefront of research, this book offers both a modern source of reference for the experienced researchers as well as a high-level introductory text for postgraduate students and nonspecialist researchers working in related areas.

A collection of sixteen coordinated reviews on the origins of large-scale magnetic fields in the Universe, this book discusses magnetic fields in all relevant astrophysical contexts, from the interstellar medium to the scales of galaxies and clusters of galaxies. Magnetic fields are described in their very diverse environments, from stellar winds to galactic haloes and astrophysical jets; together with the roles they play in forming the structures and shaping the dynamics of these objects. Both observational evidence and its theoretical interpretations are covered up to the largest scales in the Universe. The authors are all leading scientists in their fields, making this book an authoritative, up-to-date and enduring contribution to astrophysics. This volume is aimed at graduate students and researchers in astrophysics. Previously published in Space Science Reviews journal, Vol. 166/1-4 and Vol. 169/1-4, 2012.

The subject of interstellar magnetic fields is of increasing interest to both observational and theoretical astronomers. Consequently, it was opportune for both groups to convene and discuss the current state of research and future prospects. For this purpose, the Max-Planck-Gesellschaft zur Forderung der Wissenschaften e.V. generously provided its unique conference centre SchloB Ringberg. The scientific organising committee consisted of Profs. W. Hillebrandt (Max-Planck-Institut fUr Physik und Astrophysik, Munchen) and R. Wielebinski (Max-Planck-Institut fUr Radioastronomie, Bonn). The lo- cal organising committee comprised Gabriele Breuer (conference secretary) and the Editors. ' These proceedings summarise the lectures and short contributions pre- sented at the workshop. Although extremely productive, the discussions could not, unfortunately, be included. We thank the staff of the castle, and especially its administrator, Mr. Hormann, for providing the excellent environment conducive to smooth run- ning of the conference. We acknowledge the Max-Planck-Gesellschaft for its support in financing the workshop. Thanks are also due to all participants for their enthusiasm and (generally!) prompt submission of manuscripts. Last but not least, we thank Gabriele Breuer for her invaluable help before, dur- ing and after the days at SchloB Ringberg. She skillfully typed and retyped many of the manuscripts for these proceedings and unstintingly performed last minute corrections. We hope that some of the ideas presented here will stimulate further discussion and research in this area. R.Beck Bonn, December 1986 R.

Dieses Handbuch soll dem astronomisch interessierten Laien, dem Amateurastronomen ebenso wie dem Lehrer in der Schule Anleitungen fur die praktische astronomische Betatigung geben. Die sturmische Entwicklung der technischen und organisatorischen Voraussetzungen fur die Amateurbeobachtungen hat in der 4. Auflage in allen Kapiteln, einschliesslich einiger neuer Kapitel, ihren Niederschlag gefunden und zu einer deutlichen Erweiterung des Umfangs auf nunmehr 2 Bande, die einzeln erhaltlich sind. Aus den Besprechungen: ..". Die auf hochwertigem Papier gedruckten Beitrage sind ... im astronomischen Bereich einmalig. ... mustergultiges Fachbuch ... ersetzt muhelos eine sehr gute Bucherzusammenstellung, ... und ist dabei dennoch preiswerter als diese." "Rudolf-Romer-Sternwarte Mitteilungen" #1 Band 2 "Beobachtung und Praxis" stellt die Objekte der astronomischen Beobachtung (Sonnensystem, Fixsternwelt, Milchstrassensystem, extragalaktische Systeme) vor und gibt Anleitungen fur Beobachtungen, Messungen und Auswertungen im einzelnen. Band 1 "Technik und Theorie" informiert uber das grosser und leistungsfahiger gewordene instrumentelle Angebot fur Amateurastronomen, z.B. neuartige Strahlungsempfanger, moderne Halbleitertechnologie und elektronische Datenverarbeitung. Wichtige Methoden der Beobachtung und Datengewinnung (z.B. Photographie, Spektroskopie, Photometrie) werden ausfuhrlich in eigenen Kapiteln behandelt."

The book examines seven speeches by Hitler from the period 1933 to 1944 (including a first edition in the Appendix). Political speech-making is understood as an instance of communicative interplay between speaker and audience. Its dialogic structure is foregrounded with reference to the guiding concept of Emphase (emphatic oratory) and by means of interrelated, quantifying rhetorical analysis (style, prosody, semantics) and the links between those factors and active audience response. In the referential relationship between the speeches and their historical context we see the way in which the degree of political rhetoric employed and its 'success' or 'failure' are conditioned by situational factors. The insights gained from linguistic interaction analysis reflect the course taken by historical events.

Im Zentrum der Handlung steht die kleine Familie Westphal, die aus der DDR den Weg in die Freiheit sucht. Zahlreiche Ruckblenden arbeiten die Vergangenheit und damit ein Stuck DDR-Geschichte auf. An vielen Beispielen wird ein Abbild der Gesellschaft gegeben und der ganze Verwandten-, Freundes- und Bekanntenkreis auf den Prufstand gestellt. Nur wenige dieser Beziehungen halten, dafur gibt es neue Freunde und ermutigende Beispiele von Zivilcourage. Durch die Auswertung von Stasiakten wurde es dem Autor moglich, in parallelen Handlungsstragen das Verhalten der Behorden, der Stasi und der Protagonisten mit zu verfolgen. Zahlreiche Zitate aus diesen Akten lassen den Leser hautnah am Geschehen teilnehmen und machen den Roman zu einem Dokument der Zeitgeschichte.
