Book excerpt: La problématique du transport de la donnée médicale, de surcroît nominative, comporte de nombreuses contraintes, qu'elles soient d'ordre technique, légale ou encore relationnelle. Les nouvelles technologies, issues particulièrement des grilles informatiques, permettent d'offrir une nouvelle approche au partage de l'information. En effet, le développement des intergiciels de grilles, notamment ceux issus du projet européen EGEE, ont permis d'ouvrir de nouvelles perspectives pour l'accès distribué aux données. Les principales contraintes d'un système de partage de données médicales, outre les besoins en termes de sécurité, proviennent de la façon de recueillir et d'accéder à l'information. En effet, la collecte, le déplacement, la concentration et la gestion de la donnée, se fait habituellement sur le modèle client-serveur traditionnel et se heurte à de nombreuses problématiques de propriété, de contrôle, de mise à jour, de disponibilité ou encore de dimensionnement des systèmes. La méthodologie proposée dans cette thèse utilise une autre philosophie dans la façon d'accéder à l'information. En utilisant toute la couche de contrôle d'accès et de sécurité des grilles informatiques, couplée aux méthodes d'authentification robuste des utilisateurs, un accès décentralisé aux données médicales est proposé. Ainsi, le principal avantage est de permettre aux fournisseurs de données de garder le contrôle sur leurs informations et ainsi de s'affranchir de la gestion des données médicales, le système étant capable d'aller directement chercher la donnée à la source.L'utilisation de cette approche n'est cependant pas complètement transparente et tous les mécanismes d'identification des patients et de rapprochement d'identités (data linkage) doivent être complètement repensés et réécris afin d'être compatibles avec un système distribué de gestion de bases de données. Le projet RSCA (Réseau Sentinelle Cancer Auvergne - www.e-sentinelle.org) constitue le cadre d'application de ce travail. Il a pour objectif de mutualiser les sources de données auvergnates sur le dépistage organisé des cancers du sein et du côlon. Les objectifs sont multiples : permettre, tout en respectant les lois en vigueur, d'échanger des données cancer entre acteurs médicaux et, dans un second temps, offrir un support à l'analyse statistique et épidémiologique.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Business is like war: The best combatant wins while the worst loses, right? Not necessarily. Companies can succeed spectacularly without destroying others. And they can lose miserably after competing well. Exceptional businesses win by actively shaping the game they're playing, not playing the game they find. The Right Game shows you how to do this—by altering who's competing, what value each player brings to the table, and which rules and tactics players use. Since 1922, Harvard Business Review has been a leading source of breakthrough ideas in management practice. The Harvard Business Review Classics series now offers you the opportunity to make these seminal pieces a part of your permanent management library. Each highly readable volume contains a groundbreaking idea that continues to shape best practices and inspire countless managers around the world.

Book excerpt: This book is a significant contribution to the subject of mining time-changing data streams and addresses the design of learning algorithms for this purpose. It introduces new contributions on several different aspects of the problem, identifying research opportunities and increasing the scope for applications. It also includes an in-depth study of stream mining and a theoretical analysis of proposed methods and algorithms. The first section is concerned with the use of an adaptive sliding window algorithm (ADWIN). Since this has rigorous performance guarantees, using it in place of counters or accumulators, it offers the possibility of extending such guarantees to learning and mining algorithms not initially designed for drifting data. Testing with several methods, including Naïve Bayes, clustering, decision trees and ensemble methods, is discussed as well. The second part of the book describes a formal study of connected acyclic graphs, or 'trees', from the point of view of closure-based mining, presenting efficient algorithms for subtree testing and for mining ordered and unordered frequent closed trees. Lastly, a general methodology to identify closed patterns in a data stream is outlined. This is applied to develop an incremental method, a sliding-window based method, and a method that mines closed trees adaptively from data streams. These are used to introduce classification methods for tree data streams.

Available in PDF, EPUB and Kindle. Book excerpt: The prize-winning book Organizational Intelligence focuses on the structural and ideological roots of intelligence (informational and analytical) failures in government, industry, and other institutions. It provides groundbreaking theory and structure to the analysis of decision-making processes and their breakdowns, as well as the interactions among experts and the organizations they inform. In this book, both "organization" and "intelligence" are taken to their larger meanings, not just focused on the military meaning of intelligence or on one set of institutions in society. Astute illustrations of intelligence failures abound from real-world cases, such as foreign policy (the Bay of Pigs, Soviet predictions in the Cuban missile crisis), military (civilian bombing of Germany, Pearl Harbor), financial (AmEx's investment in a vegetable oil guru), economics (the Council of Economic Advisers) and industrial production (Ford's Edsel), as well as many other telling arenas and disciplines. Economic, cultural, legal, and political contexts are considered, as well as the more known institutions of government and commerce. The new Classics of the Social Sciences edition from Quid Pro Books features a 2015 Foreword from Neil J. Smelser, University Professor Emeritus at Berkeley and former chair of its sociology department. He writes that the book remains "one of the classics in organizational studies, and—in ways I will indicate—it is still directly relevant to current and future problems of organizational life. ... What makes this book a classic? It is a disciplined, intelligent, and elegant model of applied social science. ... The text itself, richly documented empirically, yields an informed and balanced account of the decision-making process as this is shaped by the quality of information available (and unavailable) to and used (and not used) by organizational leaders." Reviews of the book at the time it was written similarly attest to the originality and breadth of its interdisciplinary analysis. Amitai Etzioni wrote in the American Sociological Review: "This book opens a whole new field — the macrosociology of knowledge. It is as different from the traditional sociology of knowledge as the study of interaction is from that of the structure of total societies." He adds, "The power of Wilensky's contribution is further magnified by his historical perspective. He studies structures and processes, but not in a vacuum." Gordon Craig wrote in The Reporter that the book's examples from organizations "show a similar tendency to believe what they want to believe, to become the victims of their own slogans and propaganda, and to resist or to silence warning voices that challenge their assumptions.... In his fascinating analysis of intelligence failures and their causes ... in the public and private sectors, Wilensky finds that the most disastrous miscalculations are those which have occurred in the field of governmental operations, especially foreign policy and national security." The book explains how such highly institutionalized actors are vulnerable to informational pathologies. The new digital edition features active Contents, a fully linked Index, linked notes, and proper ebook formatting. It is a modern, quality, and authorized re-presentation of a classic work in social science and organizational studies.
