Buch. Zustand: Neu. Neuware - A thorough analysis of insider trading requires the integration of law and finance, and this book presents a theoretical and empirical examination of insider trading by incorporating a synthesis of securities law with that of financial theory. The book begins with a conceptual framework that explores the theoretical roles of markets, firms and publicly held corporations, including a discussion of corporate governance to determine both who may have access to nonpublic information, and their legal rights and responsibilities. The book then examines different aspects of the securities laws, including the Securities Act of 1933, the Securities Exchange Act of 1934, and a critique of the SEC disclosure rules and their ramifications for market efficiency. This is followed by a detailed chronology of insider trading regulations enacted in the U.S. since 1934 and an overview of the existing empirical literature on insider trading. Empirical evidence is presented on insider trading activities and the merit of anti-insider trading laws is evaluated on theoretical arguments and recent empirical developments. The authors conclude by arguing that insider trading laws and enforcement activities have failed and propose the decriminalization of insider trading.

Buch. Zustand: Neu. Neuware - This volume comprises over fifty contributions resulting from the Ocean Reverberation Symposium, held 25--29 May 1992 in La Spezia, Italy. The contributions are presented in eight sections: Scattering Mechanisms, High Frequency Measurements and Mechanisms, Reverberation Modelling, ARSRP Mid-Atlantic Ridge Experiment, Low Frequency Measurements, Volume Scattering, Signal Processing Issues, and Applications respectively. This book addresses the emerging trends in ocean reverberation research. The availability of high-power, low-frequency sources and highly directional arrays has brought with it the tools, and the need, to study long-range reverberation. The use of projector sources and various waveforms rather than explosives allows the use of signal processing techniques to enhance the extraction of information about the reverberation and scattering processes.

The book features a diskette containing programs for iron ERP spectral simulation and ENDOR analyses.

Buch. Zustand: Neu. Neuware - Highlighting the importance to ecological studies of incorporating humans and their effects on ecosystems, leading experts from a variety of disciplines address a number of important issues, including:\* the prominent role of humans in the function of ecosystems on Earth\* why humans have been ignored in ecological studies\* approaches taken by social scientists, historians, geographers, economists, and anthropologists in the study of human activities\* the emergence of a new ecological paradigm accommodating human activities\* methods for studying subtle human effects, and human- populated ecosystems \* future research and training required to include humans effectively as components of ecological systems. Of interest to students and researchers in ecology, and to policy-makers and environmental managers. In addition, it makes social scientists aware of new opportunties for integrating their ideas with those of ecologists.

Buch. Zustand: Neu. Neuware - Main Economic Policy Areas of the EC: After 1992 is a completely rewritten version of past editions. It examines successes and problems associated with the EC's main economic policy areas and makes proposals for the future. For the first time, a chapter on the very important policy area of transport is included.This volume is an indispensable course book and handbook for all individuals interested in the European Community's main policy areas at the beginning of the coming into effect of the Single European Market.

Buch. Zustand: Neu. Neuware - The common bean (Phaseolus vulgaris L.) is the most important pulse crop in Latin America, as well as in large parts of Asia and Africa. It is particularly important due to its ability, in symbiosis with Rhizobium bacteria, to fix atmospheric nitrogen and due to its high nutrient value.Incorporating contributions from plant breeders, microbiologists, plant physiologists and soil scientists, this volume reports the results of an FAO/IAEA Coordinated Research Programme (1985--1991), whose main objective was to enhance yield and biological nitrogen fixation in common bean by reducing its reliance on soil and fertilizer nitrogen.The volume will be invaluable to scientists working on biological nitrogen fixation and legume production.

Buch. Zustand: Neu. Neuware - Nature is totally amoral! There are at least 3-4 million people in France alone who suffer from arterial hypertension, and whose cardiovascular system is submitted day and night to both a haemodynamic and hormonal stress. In all cases, the vasculature hypertrophies as does the myocardium. This growth process is obviously mainly detrimental at the outset since it lowers compliance of the arteries and makes them stiffer. In contrast, myocardial hypertrophy is initially beneficial since the growth process multiplies the number of contractile units and by so doing improves external work. In addition, according to Starling's law, wall stress is lowered. Growth factors playa major role in this amoral process as a trigger for hypertrophy at the vascular level, and very likely at the level of the myocardium. Another major point of interest is the role of growth factors as determinants of restenosis after angioplasty and also of atherogenesis. Several chapters in this book are directly or indirectly concerned with this problem which is far from being purely academic since several groups are currently trying to control these processes by gene transfer. Certainly, one of the major clinical questions arising from such studies is why restenosis is not more frequent in clinical practice. After de-endotheliazation, the biologist would predict on the basis of recent studies on growth factors, and in contrast with current clinical opinion, that hypertrophy would occur in all cases with more or less complete restenosis.

Taschenbuch. Zustand: Neu. Neuware - In der Antike mythisch verklärt, später als Rohstoffquelle verbraucht, sind Wale und Delphine mittlerweile zu Publikumslieblingen und Symboltieren des Naturschutzes geworden. Wolfgang Gewalt pflegt seit mehr als einem Vierteljahrhundert fast täglichen Umgang mit diesen faszinierenden Tieren - im Zoo und draußen im freien Meer. Er erzählt von der Herkunft der Wale und Delphine, ihrem Lernvermögen, ihrer Sprache und ihrem Verhalten. Locker und verständlich erhält der Leser damit einen unmittelbaren Einblick in den heutigen Stand der Walkunde.

Taschenbuch. Zustand: Neu. Neuware - Das Buch gibt einen umfassenden Überblick über die Hardware- und Software-Konzepte, auf denen moderne Rechnersysteme beruhen, von den Arbeitsplatzrechnern bis zu den Supercomputern und den zukünftigen massiv-parallelen Rechnern. Im Anschluß an die Betrachtung der Architektur sequentieller Rechner, ihrer Prozessoren und ihrer Speicherhierarchien werden die Grundlagen für die Parallelarbeit dargelegt. Zunächst werden die Prinzipien der Parallelarbeit im Prozessor behandelt, was zu den VLIW-Maschinen und den superskalaren Prozessoren führt, und die damit verbundenen Compilerprobleme erörtert. Ein Kapitel ist den SIMD-Architekturen in Form der Vektormaschinen oder der Anordnungen gleichartiger Rechnerelemente gewidmet. Ein eigenes Kapitel stellt ausführlich und mit Beispielen die Prinzipien der Datenstruktur-Architekturen und der Sprach-Architekturen dar. Datenstruktur-Architekturen sind dahingehend optimiert, datenparallele Anwendungen mit komplexen Datenstrukturtypen möglichst effizient zu bearbeiten. Sprach-Architekturen dienen der Unterstützung von Sprachen wie Lisp und Prolog. Datenflußarchitekturen werden in einem eigenen Kapitel ausführlich behandelt. Die letzten drei Kapitel sind den Parallelrechnern gewidmet: Aus den Programmiermodellen für massiv-parallele Architekturen werden die verschiedenen Architekturformen abgeleitet. Die Eigenschaften der einzelnen Architekturformen, die zentrale Frage der Kommunikationslatenz und die spezifischen Softwarefragen werden gründlich behandelt. Das Buch zeichnet sich durch eine sehr systematische Darstellung aus sowie auch dadurch, daß nicht nur auf die Hardware-Architekturen eingegangen wird, sondern ebenso sehr auf die relevanten Fragen der Systemsoftware und Programmierung.
