Practical and easy to understand, DATABASE SYSTEMS: DESIGN, IMPLEMENTATION, AND MANAGEMENT, Tenth Edition, gives readers a solid foundation in database design and implementation. Filled with visual aids such as diagrams, illustrations, and tables, this market-leading book provides in-depth coverage of database design, demonstrating that the key to successful database implementation is in proper design of databases to fit within a larger strategic view of the data environment. Renowned for its clear, straightforward writing style, the tenth edition has been thoroughly updated to include hot topics such as green computing/sustainability for modern data centers, the role of redundant relationships, and examples of web-database connectivity and code security. In addition, new review questions, problem sets, and cases have been added throughout the book so that readers have multiple opportunities to test their understanding and develop real and useful design skills.
La République démocratique du Congo). Il dresse d’abord un état des lieux du paysage médiatique et du contexte politique post-conflit, où une paix fragile favorise une certaine ouverture démocratique mais où les médias restent confrontés à de nombreuses contraintes professionnelles, économiques, politiques et juridiques. L’ouvrage montre que malgré une augmentation du nombre d’organes de presse et une forme de pluralisme, les médias ont du mal à jouer pleinement leur rôle citoyen notamment en raison de pressions politiques, de cadres réglementaires insuffisants, de dépendances financières et de faible professionnalisation. Enfin, il propose des recommandations pour renforcer le professionnalisme, l’indépendance et la responsabilité des médias, afin qu’ils puissent contribuer efficacement à l’accès du public à une information diversifiée, au contrôle de l’action publique et, plus largement, au développement démocratique dans la région
L’ouvrage dresse un diagnostic détaillé du secteur médiatique en République démocratique du Congo (RDC) à la fin des années 2000, en examinant comment les médias congolais se sont développés, les défis qu’ils rencontrent et leurs possibles contributions à la démocratie et à la vie publique.
L’ouvrage se penche sur le rôle des médias pendant les conflits armés en Afrique centrale et s’interroge sur leur capacité à être neutres, destructeurs ou constructeurs de paix. Il rappelle notamment l’impact dramatique que peuvent avoir des médias comme la Radio des Mille Collines dans le génocide rwandais, tout en explorant des expériences de médias « humanitaires » et de paix dans divers pays de la région.

Database System Concepts by Silberschatz, Korth and Sudarshan is now in its 7th edition and is one of the cornerstone texts of database education. It presents the fundamental concepts of database management in an intuitive manner geared toward allowing students to begin working with databases as quickly as possible. The text is designed for a first course in databases at the junior/senior undergraduate level or the first year graduate level. It also contains additional material that can be used as supplements or as introductory material for an advanced course. Because the authors present concepts as intuitive descriptions, a familiarity with basic data structures, computer organization, and a high-level programming language are the only prerequisites. Important theoretical results are covered, but formal proofs are omitted. In place of proofs, figures and examples are used to suggest why a result is true.
Welcome to the eighth edition of Computer Networking: A Top-Down Approach. Since the publication of the first edition 20 years ago, our book has been adopted for use at many hundreds of colleges and universities, translated into 14 languages, and used by over one hundred thousand students and practitioners worldwide. We ve heard from many of these readers and have been overwhelmed by the positive response. The 8th Edition of the popular Computer Networking: A Top Down Approach builds on the authors’ long tradition of teaching this complex subject through a layered approach in a “top-down manner.” The text works its way from the application layer down toward the physical layer, motivating students by exposing them to important concepts early in their study of networking. Focusing on the Internet and the fundamentally important issues of networking, this text provides an excellent foundation for students in computer science and electrical engineering, without requiring extensive knowledge of programming or mathematics. The 8th Edition has been updated to reflect the most important and exciting recent advances in networking, including software-defined networking (SDN) and the rapid adoption of 4G/5G networks and the mobile applications they enable.
OSTEP ("oh step"), or the "the comet book," represents the culmination of years of teaching intro to operating systems to both undergraduates and graduates at the University of Wisconsin-Madison Computer Sciences department for nearly 20 years. The book is organized around three concepts fundamental to OS construction: virtualization (of CPU and memory), concurrency (locks and condition variables), and persistence (disks, RAIDS, and file systems). The material, if combined with serious project work and homeworks, will lead students to a deeper understanding and appreciation of modern OSes. The authors, Remzi and Andrea Arpaci-Dusseau, are both professors of Computer Sciences at the University of Wisconsin-Madison. They have been doing research in computer systems for over 20 years, working together since their first graduate operating systems class at U.C. Berkeley in 1993. Since that time, they have published over 100 papers on the performance and reliability of many aspects of modern computer systems, with a special focus on file and storage systems. Their work has been recognized with numerous best-paper awards, and some of their innovations can be found in the Linux and BSD operating systems today.
L’ouvrage Notions de Droit Civil de Jean Christophe Wérenne est un manuel pédagogique qui expose les principes fondamentaux du droit civil, destiné principalement aux étudiants de première année. Il commence par définir les grandes notions juridiques comme le droit objectif (ensemble des règles qui organisent la vie en société) et les droits subjectifs (prérogatives reconnues à une personne individuelle) ainsi que les différentes branches du droit (privé, public, international). La première partie traite des personnes et de la personnalité juridique, c’est à dire de ce qui fait qu’une personne (physique ou morale) est titulaire de droits et d’obligations, ainsi que des notions de domicile, état civil, nationalité, capacité juridique et des exemples d’actes juridiques. Ensuite, l’ouvrage aborde les obligations en droit civil : lien juridique par lequel une personne (le débiteur) est tenue envers une autre (le créancier) d’accomplir une prestation (faire, donner ou ne pas faire quelque chose), puis les espèces de contrats, les conditions de validité et les effets des conventions.
