Das Wort "Ereignis" (evenement) figuriert in den Texten Derridas von Husserls Wegin die Geschichte am Leitfaden der Geometrie (Derrida 1987; frz. Orig.: 1962) bis hin zu seinen jüngsten Texten (vgl. z.B. Derrida 2001a) in sehr unterschiedlicher Weise, mal beiläufig, mal mit Gewicht, mal als attackierte, mal als heranzitierte oder auch deutlich in Anspruch genommene Kategorie. Nichts liegt näher als der Versuch, das eigentliche Ereignis-Denken Derridas auf eine bestimmte Gruppe von Texten, eine bestimmte Phase seines Werkes zu beschränken. Schon die Form (...) der besonderen textuellen Konfiguration, die die Signatur Derridas trägt, spricht allerdings gegen ein solches Vorgehen: Es handelt sich um eine Konfiguration von Texten, die durch Insistenz und Rekurrenz gekennzeichnet ist, in diesem Sinne eher eine "durchlaufende" Kette bildet und dabei zugleich durch das laufende auf sich Zurückkommen die früheren Glieder der Kette in ein jeweils neues Licht setzt. Jenseits dieses allgemeinen Arguments spricht gegen eine Beschränkung auf einen vermeintlich homogenen Ausschnitt aus Derridas Werk zudem die spezifische Hypothese, dass die Besonderheit des Ereignisses bei Derrida darin liegt, dass es eine Reihe von Oppositionen auf spezifische Weise durchstreicht, die zum Teil eher zwischen Texten als in einer frontalen Aussage Derridas durchquert werden. Daher nehme ich in diesem Beitrag, in der textuellen Kette Derridas zurück- und vorlaufend, eine Reihe von Bestimmungsmomenten des Ereignisses auf, ohne mich auf eine Phase oder ein vorab begrenztes Feld bezogener Begriffe zu beschränken.

The paper illustrates how organic chemists dramatically altered their practices in the middle part of the twentieth century through the adoption of analytical instrumentation - such as ultraviolet and infrared absorption spectroscopy and nuclear magnetic resonance spectroscopy - through which the difficult process of structure determination for small molecules became routine. Changes in practice were manifested in two ways: in the use of these instruments in the development of 'rule-based' theories; and in an increased focus on synthesis, at the expense (...) of chemical analysis. These rule-based theories took the form of generalizations relating structure to chemical and physical properties, as measured by instrumentation. This 'Instrumental Revolution' in organic chemistry was two-fold: encompassing an embrace of new tools that provided unprecedented access to structures, and a new way of thinking about molecules and their reactivity in terms of shape and structure. These practices suggest the possibility of a change in the ontological status of chemical structures, brought about by the regular use of instruments. The career of Robert Burns Woodward (1917-1979) provides the central historical examples for the paper. Woodward was an organic chemist at Harvard from 1937 until the time of his death. In 1965, he won the Nobel Prize in Chemistry. (shrink)

This major intellectual response to the leading theologian of liberal Judaism provides a significant indication of future directions in Jewish religious thought.

A major distinction in the social organization of ant societies is the number of reproductive queens that reside in a single colony. The fire ant Solenopsis invicta exists in two distinct social forms, one with colonies headed by a single reproductive queen and the other containing several to hundreds of egg‐laying queens. This variation in social organization has been shown to be associated with genotypes at the gene Gp‐9. Specifically, single‐queen colonies have only the B allelic variant of this gene, (...) whereas multiple‐queen colonies always have the b variant as well. Subsequent studies revealed that Gp‐9 shares the highest sequence similarity with genes encoding pheromone‐binding proteins (PBPs). In other insects, PBPs serve as central molecular components in the process of chemical recognition of conspecifics. Fire ant workers regulate the number of egg‐laying queens in a colony by accepting queens that produce appropriate chemical signals and destroying those that do not. The likely role of GP‐9 in chemoreception suggests that the essential distinction in colony queen number between the single and multiple‐queen form originates from differences in workers' abilities to recognize queens. Other, closely related fire ant species seem to regulate colony social organization in a similar fashion. BioEssays 27:91–99, 2005. © 2004 Wiley Periodicals, Inc. (shrink)

Illustrations: 13 B/w & 1 Colour Illustrations Description: The frontiers of Traditional Knowledge and Science have long attracted the minds of scientists, theologians, intellectuals and students, who have been arguing both their similarities and dissimilarities, apparent contradictions, and the possibility of an ultimate harmony between the two. In ancient and medieval India - as in much of the Non-Western world - there was only one word for tradition and science, namely, vidya. Vidya encompassed what in the modern historically-sensitive inquiries is (...) called 'knowledge-systems.' However, in the modern West, placing Science and Tradition side-by-side has become something of an anathema, for many in the post-Enlightenment era regard Tradition to be a leftover from the Dark Ages. Science, in contrast, with its systematic approach to studying and understanding of all there is, has been considered to be unassailable. But even this impenetrable divide may be showing signs of rupture in the twenty-first century : there is now growing evidence of a line of continuity and creative engagement in a 'third space' between Science and Traditional Knowledge. Individuals and learned organizations are making enormous contributions in this interactive exploration. The Sir John Templeton Foundation, based in Philadelphia, USA, is one such international organization. Professor B.V. Subbarayappa is one such eminent scholar who has relentlessly pursued, and in his quiet way stimulated, the fusion of disparate minds in this area. He is hailed as a pioneer in the History and Philosophy of Science movement in India. His contributions in this field are without match and have earned him a name among scientists, science historians, philosophers and intellectuals all over the world. His monumental work and his sheer humanity have inspired the Editors of this volume to find a way to honour him. Scholars of various persuasions from around the world have contributed exploratory, specialist and dialogic essays toward this conversation of Science and Tradition. A biographical sketch with a comprehensive Bibliography (first-ever) of Prof Subbarayappa is also featured in the Introductory essay. Professor--D.P. Chattopadhyaya and J.N. Mohanty have offered prefatory comments of their own. Given the extensive range of topics discussed, both specialists and lay readers will doubtless gain a deeper understanding of the relationship between Science and Tradition in a cross-cultural context, and hopefully be inspired to develop respect for knowledge across these two frontiers.
