Download or read book The Ungovernable Society written by Grégoire Chamayou and published by Polity. This book was released on 2021-05-03 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rebellion was in the air. Workers were on strike, students were demonstrating on campuses, discipline was breaking down. No relation of domination was left untouched – the relation between the sexes, the racial order, the hierarchies of class, relationships in families, workplaces and colleges. The upheavals of the late 1960s and early 1970s quickly spread through all sectors of social and economic life, threatening to make society ungovernable in the eyes of ruling elites. This crisis was also the birthplace of the authoritarian liberalism which continues to cast its shadow across the world in which we now live. To ward off the threat, new arts of government were devised in business-related circles, which included a war against the trade unions, the primacy of shareholder value and a dethroning of politics. The neoliberalism that thus began its triumphal march was not, however, determined by a simple ‘state phobia’ and a desire to free up the economy from government interference. On the contrary, the strategy for overcoming the crisis of governability consisted in an authoritarian liberalism in which the liberalization of society went hand-in-hand with new forms of power imposed from above: a ‘strong state’ for a ‘free economy’ became the new magic formula of our capitalist societies. Grégoire Chamayou analyses this crisis as it was perceived and theorized in the 1970s by those who strove to defend the interests of business – that is, the ruling elites, especially in the United States, from which a far-reaching intellectual and political movement spread. The new arts of government they devised are still with us today and we can understand their nature and lasting influence only by re-examining the history of the conflicts that brought them into being.

This book was released on 1981-01-01T00:00:00+01:00 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Au cours des prochaines années, l'utilisation des systèmes informatiques répartis deviendra une des composantes essentielles de notre société. Le succès de leurs applications dépendra, étroitement, de la conception des systèmes de gestion des bases de données, réparties (SGBDR) en vue de leur bonne adaptation aux besoins des utilisateurs. C'est pourquoi les utilisateurs et les informaticiens doivent réfléchir, dès maintenant, aux problèmes que pose la conception de ces nouveaux systèmes. Le but de ce livre, actuellement unique en son genre en langue française, est d'aider les uns et les autres dans cette tâche. Il propose une analyse détaillée et progressive, en vue d'identifier les problèmes et de choisir les solutions, qui jalonnent le processus de la conception d'un SGBDR. Il permet de comprendre les principes de base de ces systèmes, et d'en connaître, précisément et complètement, les possibilités fonctionnelles. Cette analyse privilégie, en effet, l'étude des interactions entre les besoins des utilisateurs et les spécifications du système : c'est dans la conformité de celles-ci à ceux-là, plus que dans les processus techniques, que se joue l'avenir de cette informatique. L'ouvrage s'adresse donc à la fois aux utilisateurs, auxquels la clarté de la rédaction le rend facilement accessible, aux ingénieurs qui ont à évaluer l'apport de ces nouvelles techniques, aux informaticiens, qui auront à concevoir des systèmes répartis, et aux chercheurs qui veulent s'initier à ce domaine de l'informatique. Les principaux points abordés par l'auteur sont les suivants : - pourquoi recourir à l'informatique répartie ? - qu'est-ce qu'un système de gestion de bases de données réparties ? - définition de l'environnement réparti et de l'environnement local ; - définition du schéma global d'un SGBDR ; - la répartition des données ; - l'architecture du système, les différentes fonctions ; - les utilisateurs face à la répartition. L'ouvrage est complété par deux chapitres, l'un sur les tendances actuelles de la recherche, l'autre sur les conséquences de l'informatique répartie sur la vie des entreprises, sur les libertés individuelles et sur le développement de l'informatique.

Download or read book Parallel Scientific Computing written by Frédéric Magoules and published by John Wiley & Sons. This book was released on 2016-01-26 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific computing has become an indispensable tool in numerous fields, such as physics, mechanics, biology, finance and industry. For example, it enables us, thanks to efficient algorithms adapted to current computers, to simulate, without the help of models or experimentations, the deflection of beams in bending, the sound level in a theater room or a fluid flowing around an aircraft wing. This book presents the scientific computing techniques applied to parallel computing for the numerical simulation of large-scale problems; these problems result from systems modeled by partial differential equations. Computing concepts will be tackled via examples. Implementation and programming techniques resulting from the finite element method will be presented for direct solvers, iterative solvers and domain decomposition methods, along with an introduction to MPI and OpenMP.

Book excerpt: Conception de bases de données : la fin de l'ère Merise. Conçu au départ pour modéliser des applications orientées objet (écrites par exemple en C++ ou en Java), UML s'est peu à peu imposé sur le terrain de la conception de bases de données relationnelles, au détriment du vénérable modèle entité-association, qui fut popularisé en France par la méthode Merise. Des diagrammes UML au code SQL. Destiné aussi bien aux étudiants qu'aux professionnels qui souhaitent évoluer vers UML, cet ouvrage explique comment construire un modèle conceptuel sous forme de diagramme de classes, comment transformer ce dernier en modèle de données relationnel ou objet-relationnel, pour générer au final le code SQL2 ou SQL3 souhaité. Panorama des outils de modélisation. Le dernier chapitre présente cinq outils du marché, Win'Design, PowerAMC, Rational Rose, Oracle Designer et JDeveloper, à l'aide desquels sont illustrées de manière concrète les différentes phases de la conception d'une base de données, de la modélisation Merise ou UML à la génération de code SQL. Chaque chapitre est accompagné d'exercices dont le corrigé est fourni en fin d'ouvrage. A qui s'adresse ce livre ? • Aux étudiants en IUT, IUP, DEUG ou écoles d'ingénieur, ayant à leur programme des cours sur les bases de données. • Aux professionnels souhaitant s'initier à la modélisation de bases de données avec UML. • A tout concepteur de bases de données souhaitant migrer de Merise à UML.
