This book deals with the way that the auditory system processes acoustic signals. The current edition has been revised in all areas to reflect the progress that has been made since the 3rd edition. As well as dealing with the basic anatomy and physiology of all stages of the auditory system, the book relates basic physiological processes to the performance of the auditory system as a whole, in the perception of acoustic signals including speech. The chapter on sensorineural hearing loss not only describes the physiological and anatomical changes that are associated with hearing loss, but includes latest information on treatments including cochlear implants, and work being undertaken on stem cell and other cellular therapies for deafness. A reading scheme has been provided to guide readers to the section most appropriate for their interests. The book is written so that those entering auditory research from very little background in auditory neuroscience are able to understand the current research issues and the current research literature. It is also intended to be a source book and reference work for advanced undergraduates studying the special senses, and for clinicians in the specialty of Otorhinolaryngology.

Signals and Systems for Speech and Hearing (2nd edition) provides the reader with a thorough introduction to the concepts of signals and systems analysis that play a role in the speech and hearing sciences. Few equations are used, and an informal, friendly and informative style is maintained throughout. Because much of the story is told through figures, the authors have gone to great lengths to provide clear and truthful figures that show what the text says they do. It is hoped the reader will come away with a strong visual understanding of the concepts involved. This book can be used at many levels, from the student who hasn't heard of a spectrum before, to the experienced worker who has only a fuzzy understanding of the notion of an impulse response. The authors have tried to keep the underlying conceptual structure of signals and systems analysis explicit, in the hope that even some readers with advanced technical training might find clarification of the basic principles. Notable features include over 300 figures integrated closely with the text, all drawn specifically. Exercises are provided at the end of most chapters.

Patente am Leben?

Ethische, rechtliche und politische Aspekte der Biopatentierung

Edited by Christoph Baumgartner and Dietmar Mieth

Im Zuge der Entwicklung der modernen Biotechnologie zu einer Schlüsseltechnologie des 21. Jahrhunderts wurde das Patentrecht als wirtschafts- und forschungspolitisches Instrument auch auf den Bereich der belebten Natur ausgedehnt. Diese Entwicklung stößt unter ethischen Aspekten jedoch vielfach auf Bedenken – zahlreiche Fragen werden kontrovers diskutiert: • Bedeutet die Patentierung von Genen eine Kommerzialisierung des menschlichen Körpers? • Kann im Bereich des Lebendigen überhaupt sinnvoll von “Erfindung” gesprochen werden, was für die Erteilung von Patenten erforderlich ist? • Sind die Privilegien (der Forscher, der Züchter) ausreichend, um Monopolisierungen zu verhindern? Derartige Fragen wurden auch durch die EU-Richtlinie über den rechtlichen Schutz biotechnologischer Erfindungen aus dem Jahr 1998 nicht abschließend geklärt. Die Tatsache, dass diese Richtlinie in verschiedenen europäischen Ländern bislang nicht umgesetzt wurde, zeigt zudem, dass auch auf rechtlicher Ebene noch ein erheblicher Klärungsbedarf besteht. In vorliegendem Buch kommen Befürworter der Biopatentierung ebenso wie deren Kritiker zu Wort: Die Beiträger stammen u.a. aus Disziplinen wie Ethik, Politik- und Rechtswissenschaft, der pharmazeutischen Industrie und der Pflanzenzüchtung. Die angefügten Dokumente, die EU-Biopatentierungsrichtlinie und zwei Stellungnahmen der Ethik-Beratergruppe der Europäischen Kommission von 1996 und 2002 sowie ein Glossar vertiefen und erweitern die angestrebte Übersicht
