Euripides’ Ion is a highly complex and elusive play and thus poses considerable difficulties to any interpreter. On the basis of a new recension of the text, this commentary offers explanations of the language, literary technique, and realia of the play and discusses the main issues of interpretation. In this way the reader is provided with the material required for an appreciation of this entertaining as well as provocative dramatic composition.
Worldwide concern in scientific, industrial, and governmental com munities over traces of toxic chemicals in foodstuffs and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are integrated and scheduled to provide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. Until now there has been no journal or other publication series reserved exclusively for the diversified literature on «toxic" chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wild life, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, . fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authorita tive publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancillary legislation.
This textbook introduces readers to the basic concepts of quasi-Monte Carlo methods for numerical integration and to the theory behind them. The comprehensive treatment of the subject with detailed explanations comprises, for example, lattice rules, digital nets and sequences and discrepancy theory. It also presents methods currently used in research and discusses practical applications with an emphasis on finance-related problems. Each chapter closes with suggestions for further reading and with exercises which help students to arrive at a deeper understanding of the material presented. The book is based on a one-semester, two-hour undergraduate course and is well-suited for readers with a basic grasp of algebra, calculus, linear algebra and basic probability theory. It provides an accessible introduction for undergraduate students in mathematics or computer science.
That residues of pesticide and other "foreign" chemicals in food stuffs are of concern to everyone everywhere is amply attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, sincerity, and efforts shown by all the in dividuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being dis placed by newly developed ones more acceptable to food tech nologists, pharmacologists, toxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals per sisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.
English summary: Written between 2009 and 2011 the ten essays in this volume deal with problems of economic diagnosis and with forecasting, in particular forecasting of global economic developments in the first two decades of the 21st century. Based on a wide-ranging survey of the literature, Gunther Tichy's three essays show that both academic and practising economists in large numbers pointed out the unmistakable signs of a looming crash, but their warnings were ignored for political reasons, above all in the USA, where the quest for profit was not to be damped. Therefore Tichy inquires if stricter regulation of the finance sector could make its activities more transparent and development trends easier to control. In seven essays Erich Streissler analyses the financial crisis of 2008 and deals with forecasting problems. Since the late 1990s the world economy has had to register a "savings glut". In great parts, excess savings went to the USA where most of them were destroyed either by way of private and public consumption or by mis-investment. Streissler investigates several influential financial market models by US economists, some of Nobel prize fame, and shows that and why they were wrong and inapplicable. He discusses the question of an optimal probability distribution for analysing "rare events" like economic crises and ends the volume with an attempt at forecasting global economic developments. German description: Entstanden zwischen 2009 und 2011 befassen sich die hier vereinigten zehn Aufsatze mit den Themen langfristiger Wirtschaftsdiagnose und Prognose, speziell mit der Prognose globaler wirtschaftlicher Entwicklungen in den ersten zwei Jahrzehnten des 21. Jahrhunderts. In den ersten drei Aufsatzen zeigt Gunther Tichy anhand grundlicher Literaturstudien, wie es in den USA fast unmoglich war, die Augen vor der drohenden Finanzmarktkatastrophe zu verschliessen. Doch wurden alle Warnungen als zerstorerischer Defaitismus abgetan. Eine massenpsychologische Hoffnung auf Gewinne lasst sich selbst bei auffalliger Haufung drohender Symptome nicht so leicht truben. Konnte eine Regulierung des Finanz- und Bankensektors Entwicklungen auf diesem uberschaubarer und leichter vorhersagbar machen? In den folgenden sieben Aufsatzen analysiert Erich Streissler die Finanzkrise von 2008 und widmet sich vor allem Prognoseproblemen. Seit Ende der 1990er Jahre leidet die Welt unter einem Uberschuss beabsichtigter Ersparnisse. Uberschussige Weltersparnisse wurden zumal in den USA durch privaten und offentlichen Konsum vernichtet oder fuhrten zu Fehlinvestitionen. Streissler analysiert finanzmarkttheoretische Fehlurteile US-amerikanischer Nobelpreistrager und fragt nach der bestmoglichen Wahrscheinlichkeitsverteilung fur die Analyse "seltener Ereignisse" wie Wirtschaftskrisen. Sein Versuch einer Vorhersage zukunftiger Entwicklungen der Weltwirtschaft beschliesst den Band.
