Book Description
CETTE THESE PORTE SUR LA PARALLELISATION DES OPERATIONS DE L'ALGEBRE RELATIONNELLE DANS LES SYSTEMES DE GESTION DE BASES DE DONNEES ETENDUES. ELLE SE PROPOSE DONC D'ETUDIER DEUX ASPECTS DES NOUVELLES APPROCHES DANS LE DOMAINE DES BASES DE DONNEES. LE PREMIER ASPECT EST LA PARALLELISATION DES OPERATIONS DE L'ALGEBRE RELATIONNELLE ET PLUS PARTICULIEREMENT DE L'OPERATION DE JOINTURE. CETTE OPERATION EST TRES LARGEMENT UTILISEE DANS LES SYSTEMES RELATIONNELS ET ELLE FAIT INTERVENIR DE GRANDS VOLUMES DE DONNEES. L'OBJECTIF DE L'APPROCHE EST D'AMELIORER LES PERFORMANCES DES SYSTEMES EN PARALLELISANT CETTE OPERATION. LA PREMIERE ETAPE CONCERNE LE CHOIX D'UNE ARCHITECTURE. ENSUITE SE POSE LE PROBLEME DE CONCEPTION D'UN ALGORITHME EFFICACE DANS LE CADRE DE CETTE ARCHITECTURE. L'ALGORITHME RESULTANT DE CETTE DEMARCHE EST UNE ADAPTATION DES ALGORITHMES CLASSIQUES. L'APPROCHE CHOISIE EST INNOVATRICE PUISQU'ELLE FAIT INTERVENIR DES IDENTIFICATEURS DANS LES PHASES INTERMEDIAIRES DE L'ALGORITHME. L'INTERET DE CE MECANISME EST LA DIMINUTION DES QUANTITES DE DONNEES ECHANGEES ENTRE LES DIFFERENTES PHASES DE L'ALGORITHME. LE SECOND ASPECT CONCERNE L'EXTENSION DES BASES DE DONNEES AUX OBJETS. EN EFFET, LES SYSTEMES RELATIONNELS CLASSIQUES NE TRAVAILLENT QUE SUR DES TYPES DE DONNEES SIMPLES. OR LES NOUVELLES APPLICATIONS ONT BESOIN DE PRENDRE EN COMPTE DES STRUCTURES DE DONNEES PLUS COMPLEXES. CES DONNEES SE CARACTERISENT AUSSI PAR LEUR COMPORTEMENT. POUR PRENDRE EN COMPTE TOUTE LA SEMANTIQUE DE CES DONNEES, LES SYSTEMES CLASSIQUES SONT INSUFFISANTS. CETTE THESE PRESENTE UNE APPROCHE POSSIBLE PERMETTANT D'ETENDRE LES SYSTEMES RELATIONNELS POUR REPONDRE A CES OBJECTIFS. UNE PARTIE DU TRAVAIL EFFECTUE S'EST INSCRIT DANS LE CADRE DU PROJET ESPRIT EDS. LES DIFFERENTES ETUDES SE SONT CONCRETISEES PAR LA REALISATION DE PROTOTYPES DECRITS DANS LA THESE

Book Description
How have we thought “the body”? How can we think it anew? The body of mortal creatures, the body politic, the body of letters and of laws, the “mystical body of Christ”—all these (and others) are incorporated in the word Corpus, the title and topic of Jean-Luc Nancy’s masterwork. Corpus is a work of literary force at once phenomenological, sociological, theological, and philosophical in its multiple orientations and approaches. In thirty-six brief sections, Nancy offers us at once an encyclopedia and a polemical program—reviewing classical takes on the “corpus” from Plato, Aristotle, and Saint Paul to Descartes, Hegel, Husserl, and Freud, while demonstrating that the mutations (technological, biological, and political) of our own culture have given rise to the need for a new understanding of the body. He not only tells the story of this cultural change but also explores the promise and responsibilities that such a new understanding entails. The long-awaited English translation is a bold, bravura rendering. To the title essay are added five closely related recent pieces—including a commentary by Antonia Birnbaum—dedicated in large part to the legacy of the “mind-body problem” formulated by Descartes and the challenge it poses to rethinking the ancient problems of the corpus. The last and most poignant of these essays is “The Intruder,” Nancy’s philosophical meditation on his heart transplant. The book also serves as the opening move in Nancy’s larger project called “The deconstruction of Christianity.”

Book Description
The creation of new lexical units and patterns has been studied in different research frameworks, focusing on either system-internal or system-external aspects, from which no comprehensive view has emerged. The volume aims to fill this gap by studying dynamic processes in the lexicon – understood in a wide sense as not being necessarily limited to the word level – by bringing together approaches directed to morphological productivity as well as approaches analyzing general types of lexical innovation and the role of discourse-related factors. The papers deal with ongoing changes as well as with historical processes of change in different languages and reflect on patterns and specific subtypes of lexical innovation as well as on their external conditions and the speakers’ motivations for innovating. Moreover, the diffusion and conventionalization of innovations will be addressed. In this way, the volume contributes to understanding the complex interplay of structural, cognitive and functional factors in the lexicon as a highly dynamic domain.

Book Description
This volume provides an unparalleled exploration of ethics and museum practice, considering the controversies and debates which surround key issues such as provenance, ownership, cultural identity, environmental sustainability and social engagement. Using a variety of case studies which reflect the internal realities and daily activities of museums as they address these issues, from exhibition content and museum research to education, accountability and new technologies, Museums, Ethics and Cultural Heritage enables a greater understanding of the role of museums as complex and multifaceted institutions of cultural production, identity-formation and heritage preservation. Benefitting from ICOM’s unique position in the museum world, this collection brings a global range of academics and professionals together to examine museums ethics from multiple perspectives. Providing a more complete picture of the diverse activities now carried out by museums, Museums, Ethics and Cultural Heritage will appeal to practitioners, academics and students alike.

Book Description
Seventeenth-century Dutch and Flemish paintings were aesthetic, intellectual, and economic touchstones in the Parisian art world of the Revolutionary era, but their importance within this framework, while frequently acknowledged, never attracted much subsequent attention. Darius A. Spieth’s inquiry into Revolutionary Paris and the Market for Netherlandish Art reveals the dominance of “Golden Age” pictures in the artistic discourse and sales transactions before, during, and after the French Revolution. A broadly based statistical investigation, undertaken as part of this study, shows that the upheaval reduced prices for Netherlandish paintings by about 55% compared to the Old Regime, and that it took until after the July Revolution of 1830 for art prices to return where they stood before 1789.
