Book Description
Dans cette thèse, on considère la problématique de la stabilité et de la stabilité robuste d'une classe de systèmes linéaires / à retards distribués. Notre travail est motivé par le nombre croissant de modèles en allant de la biologie vers les réseaux de communication et de transport, modèles qui peuvent être inclus dans la classe générale considérée dans la thèse. Nous développons deux approches complémentaires, géométriques et algébriques. Ces approches nous permettent de dériver les régions de stabilité dans l'espace de paramètres défini par (délai moyen, retard de propagation). En d'autres termes, nous obtenons des conditions nécessaires et suffisantes pour la stabilité des systèmes appartenant à la classe considérée. Dans la thèse, diverses applications sont présentées. D'abord, nous précisons quelques propriétés qualitatives au sujet de la stabilité de quelques modèles en biologie et en communication dans des réseaux. Ensuite, nous développons une méthode afin d'étudier un modèle récent de la dynamique du réseau de transport qui inclut un effet de mémoire. Des exemples numériques illustratifs complètent la présentation.

Book Description
Synthesizes the empirical literature on organizationalstructuring to answer the question of how organizations structure themselves --how they resolve needed coordination and division of labor. Organizationalstructuring is defined as the sum total of the ways in which an organizationdivides and coordinates its labor into distinct tasks. Further analysis of theresearch literature is neededin order to builda conceptualframework that will fill in the significant gap left by not connecting adescription of structure to its context: how an organization actuallyfunctions. The results of the synthesis are five basic configurations (the SimpleStructure, the Machine Bureaucracy, the Professional Bureaucracy, theDivisionalized Form, and the Adhocracy) that serve as the fundamental elementsof structure in an organization. Five basic parts of the contemporaryorganization (the operating core, the strategic apex, the middle line, thetechnostructure, and the support staff), and five theories of how it functions(i.e., as a system characterized by formal authority, regulated flows, informalcommunication, work constellations, and ad hoc decision processes) aretheorized. Organizations function in complex and varying ways, due to differing flows -including flows of authority, work material, information, and decisionprocesses. These flows depend on the age, size, and environment of theorganization; additionally, technology plays a key role because of itsimportance in structuring the operating core. Finally, design parameters aredescribed - based on the above five basic parts and five theories - that areused as a means of coordination and division of labor in designingorganizational structures, in order to establish stable patterns of behavior.(CJC).

Book Description
The systems of innovation approach is considered by many to be a useful analytical approach for better understanding innovation processes as well as the production and distribution of knowledge in the economy. It is an appropriate framework for the empirical study of innovations in their contexts and is relevant for policy makers. This text is the result of the work within an international inter-disciplinary network or "working seminar" with the task of building a more solid and sophisticated conceptual and theoretical foundation for the continued study of innovations in a systemic context. The book has three parts. The first presents an overview and tries to work out some conceptual problems. In the second, the systems of innovation approach is related to innovation theory. Part three is devoted to increasing understanding of the functioning and dynamics of systems of innovation. There is also an introduction where the genesis and anatomy of different systems of innovation approaches are discussed and where the systems of innovation approach is characterized in nine dimensions.

Book Description
'The Road to Results: Designing and Conducting Effective Development Evaluations' presents concepts and procedures for evaluation in a development context. It provides procedures and examples on how to set up a monitoring and evaluation system, how to conduct participatory evaluations and do social mapping, and how to construct a "rigorous" quasi-experimental design to answer an impact question. The text begins with the context of development evaluation and how it arrived where it is today. It then discusses current issues driving development evaluation, such as the Millennium Development Goals and the move from simple project evaluations to the broader understandings of complex evaluations. The topics of implementing 'Results-based Measurement and Evaluation' and constructing a 'Theory of Change' are emphasized throughout the text. Next, the authors take the reader down 'the road to results, ' presenting procedures for evaluating projects, programs, and policies by using a 'Design Matrix' to help map the process. This road includes: determining the overall approach, formulating questions, selecting designs, developing data collection instruments, choosing a sampling strategy, and planning data analysis for qualitative, quantitative, and mixed method evaluations. The book also includes discussions on conducting complex evaluations, how to manage evaluations, how to present results, and ethical behavior--including principles, standards, and guidelines. The final chapter discusses the future of development evaluation. This comprehensive text is an essential tool for those involved in development evaluation.

Book Description
The challenge of communication in planetary exploration has been unusual. The guidance and control of spacecraft depend on reliable communication. Scientific data returned to earth are irreplaceable, or replaceable only at the cost of another mission. In deep space, communications propagation is good, relative to terrestrial communications, and there is an opportunity to press toward the mathematical limit of microwave communication. Yet the limits must be approached warily, with reliability as well as channel capacity in mind. Further, the effects of small changes in the earth's atmosphere and the interplanetary plasma have small but important effects on propagation time and hence on the measurement of distance. Advances are almost incredible. Communication capability measured in 18 bits per second at a given range rose by a factor of 10 in the 19 years from Explorer I of 1958 to Voyager of 1977. This improvement was attained through ingenious design based on the sort of penetrating analysis set forth in this book by engineers who took part in a highly detailed and amazingly successful pro gram. Careful observation and analysis have told us much about limitations on the accurate measurement of distance. It is not easy to get busy people to tell others clearly and in detail how they have solved important problems. Joseph H. Yuen and the other contribu tors to this book are to be commended for the time and care they have devoted to explicating one vital aspect of a great adventure of mankind.

Book Description
James Charlton has produced a ringing indictment of disability oppression, which, he says, is rooted in degradation, dependency, and powerlessness and is experienced in some form by five hundred million persons throughout the world who have physical, sensory, cognitive, or developmental disabilities. Nothing About Us Without Us is the first book in the literature on disability to provide a theoretical overview of disability oppression that shows its similarities to, and differences from, racism, sexism, and colonialism. Charlton's analysis is illuminated by interviews he conducted over a ten-year period with disability rights activists throughout the Third World, Europe, and the United States. Charlton finds an antidote for dependency and powerlessness in the resistance to disability oppression that is emerging worldwide. His interviews contain striking stories of self-reliance and empowerment evoking the new consciousness of disability rights activists. As a latecomer among the world's liberation movements, the disability rights movement will gain visibility and momentum from Charlton's elucidation of its history and its political philosophy of self-determination, which is captured in the title of his book. Nothing About Us Without Us expresses the conviction of people with disabilities that they know what is best for them. Charlton's combination of personal involvement and theoretical awareness assures greater understanding of the disability rights movement.

Book Description
Madness, sexuality, power, knowledge—are these facts of life or simply parts of speech? In a series of works of astonishing brilliance, historian Michel Foucault excavated the hidden assumptions that govern the way we live and the way we think. The Archaeology of Knowledge begins at the level of "things aid" and moves quickly to illuminate the connections between knowledge, language, and action in a style at once profound and personal. A summing up of Foucault's own methadological assumptions, this book is also a first step toward a genealogy of the way we live now. Challenging, at times infuriating, it is an absolutey indispensable guide to one of the most innovative thinkers of our time.
