Dialogic Education and Technology : Expanding the Space of Learning
Dialogic Education and Technology is about using new technology to draw people into the kind of dialogues which take them beyond themselves into learning, thinking and creativity. The program of research reported in this book reveals key characteristics of learning dialogues and demonstrates ways in which computers and networks can deepen, enrich and expand such dialogues. A dialogic perspective is developed drawing upon recent work in communications theory, psychology, computer science and philosophy. The central argument of the book is that there is a convergence between this dialogic perspective in education and the affordances of new information and communications technology. A genuinely dialogic perspective is relatively new to the field of educational technology and there is a considerable amount of interest in this topic amongst researchers who wish to see what extra insights, if any, a dialogical approach can offer them.
Dependence in Probability and Statistics
This book gives a detailed account of some recent developments in the field of probability and statistics for dependent data. The book covers a wide range of topics from Markov chain theory and weak dependence with an emphasis on some recent developments on dynamical systems, to strong dependence in times series and random fields. A special section is devoted to statistical estimation problems and specific applications. The book is written as a succession of papers by some specialists of the field, alternating general surveys, mostly at a level accessible to graduate students in probability and statistics, and more general research papers mainly suitable to researchers in the field. The first part of the book considers some recent developments on weak dependent time series, including some new results for Markov chains as well as some developments on new notions of weak dependence. This part also intends to fill a gap between the probability and statistical literature and the dynamical system literature. The second part presents some new results on strong dependence with a special emphasis on non-linear processes and random fields currently encountered in applications. Finally, in the last part, some general estimation problems are investigated, ranging from rate of convergence of maximum likelihood estimators to efficient estimation in parametric or non-parametric time series models, with an emphasis on applications with non-stationary data.

Cultural Convergence : The Dublin Gate Theatre, 1928–1960
Based on extensive archival research, this book examines the poetics and politics of the Dublin Gate Theatre (est. 1928) over the first three decades of its existence, discussing some of its remarkable productions in the comparative contexts of avant-garde theatre, Hollywood cinema, popular culture, and the development of Irish-language theatre, respectively. The overarching objective is to consider the output of the Gate in terms of cultural convergence – the dynamics of exchange, interaction, and acculturation that reveal the workings of transnational infrastructures.
Crossroads of Entrepreneurship
Crossroads of Entrepreneurship presents works from scholars belonging to a number of different disciplines - business history, economics, sociology and management - and addresses a cross section of issues in the entrepreneurship field. Contributions are arranged in different sections, emphasizing dialogue across disciplines and paradigms, rather than boundaries between them. The first section of the work is a compilation of papers that trace the historical roots of study in entrepreneurship in different disciplinary domains, and highlight the fundamental issues addressed by past research. A second section gathers empirical studies adopting various methods and investigating different aspects of entrepreneurial action. The third section collects contributions investigating the development of entrepreneurship in different national settings. The work reveals a convergence of issues and interests, despite paradigmatic differences, and the potential benefits of more intense conversation across disciplines.
Courbes algébriques planes = Plane Algebraic Curves
Resulting from a master's course at the University of Paris VII, this text is re-edited as it appeared in 1978. Various tools are introduced in connection with Bézout's theorem necessary for the development of the notion of the multiplicity of intersection of two algebraic curves in the complex projective plane. Starting from elementary notions on affine and projective algebraic subsets, we define the intersection multiplicities and interpret their sum in terms of the resultant of two polynomials. The local study is a pretext for the introduction of formal or convergent series rings; it culminates in Puiseux's theorem, the convergence of which is reduced by splits to that of the theorem of implicit functions. Various figures illuminate the text: we "see" in particular that the homogeneous equation x3 + y3 + z3 = 0 defines a torus in the complex projective plane.
Cortical Deficits In Schizophrenia : From Genes to Function
Opens with a chapter by Paul Harrison highlighting the several convergence points among the diverse schizophrenia-related genes. This is followed by chapters reviewing several different specific genes, including Neuregulin, DISC-1, dysbindin, and Homer, among others, and by several chapters presenting information on physiological cortical processes that could be affected by those genes. These include glutamatergic, GABAergic and cholinergic neurotransmission.Current hot topics in schizophrenia research are also highlighted in the book. A concept that is gaining strength in the field, the chapters in this book summarize the current state of affairs in schizophrenia pathophysiology, with a consideration of genetic elements that may contribute to it. Cortical Deficits in Schizophrenia: From Genes to Function will prove a useful tool for those interested in a better understanding of schizophrenia. Even if more predisposing genes (not included in this book) become identified, the work laid out here will prove critical for assigning a functional (or dysfunctional) role to those genes. Although this is a fast-evolving field, the information and concepts covered in this book will likely be useful for years to come.
Convergence or Divergence in Europe? : Growth and Business Cycles in France, Germany and Italy
The book analyses the latest developments in three largest European economies in a broad perspective, using modern econometric techniques. One of the conclusions is that, while business cycles are more strongly correlated across the three countries, as evidenced by the common reaction to the 2001 slowdown, the three countries still exhibit differences in terms of long term growth.
Convergence and Applications of Newton-type Iterations
Recent results in local convergence and semi-local convergence analysis constitute a natural framework for the theoretical study of iterative methods. This monograph provides a comprehensive study of both basic theory and new results in the area. Each chapter contains new theoretical results and important applications in engineering, modeling dynamic economic systems, input-output systems, optimization problems, and nonlinear and linear differential equations. Several classes of operators are considered, including operators without Lipschitz continuous derivatives, operators with high order derivatives, and analytic operators. Each section is self-contained. Examples are used to illustrate the theory and exercises are included at the end of each chapter.
Computational Methods in Transport : Verification and Validation
The focus of this book deals with a cross cutting issue affecting all particle transport algorithms and applications; verification and validation (V&V). In other words, are the equations being solved correctly and are the correct equations being solved? Verification and validation assures a scientist, engineer or mathematician that a simulation code is a mirror of reality and not just an expensive computer game. In this book, we will learn what the astrophysicist, atmospheric scientist, mathematician or nuclear engineer do to assess the accuracy of their code. What convergence studies, what error analysis, what problems do each field use to benchmark and ascertain the accuracy of their transport simulations.
Computational Electromagnetics
Computational Electromagnetics is a young and growing discipline, expanding as a result of the steadily increasing demand for software for the design and analysis of electrical devices. This book introduces three of the most popular numerical methods for simulating electromagnetic fields: the finite difference method, the finite element method and the method of moments. In particular it focuses on how these methods are used to obtain valid approximations to the solutions of Maxwell's equations, using, for example, "staggered grids" and "edge elements." The main goal of the book is to make the reader aware of different sources of errors in numerical computations, and also to provide the tools for assessing the accuracy of numerical methods and their solutions. To reach this goal, convergence analysis, extrapolation, von Neumann stability analysis, and dispersion analysis are introduced and used frequently throughout the book. Another major goal of the book is to provide students with enough practical understanding of the methods so they are able to write simple programs on their own. To achieve this, the book contains several MATLAB programs and detailed description of practical issues such as assembly of finite element matrices and handling of unstructured meshes.
Cognitive engineering : A distributed approach to machine intelligence
Cognitive Engineering: A Distributed Approach to Machine Intelligence explores the design issues of intelligent engineering systems. Beginning with the foundations of psychological modeling of the human mind, the main emphasis is given to parallel and distributed realization of intelligent models for application in reasoning, learning, planning and multi-agent co-ordination problems. The last two chapters provide case studies on human-mood detection and control, and behavioral co-operation of mobile robots. This is the first comprehensive text of its kind, bridging the gap between Cognitive Science and Cognitive Systems Engineering. Each chapter includes plenty of numerical examples and exercises with sufficient hints, so that the reader can solve the exercises on their own. Computer simulations are also included in most chapters to give a clear idea about the application of the algorithms undertaken in the book. In addition, mathematical analysis on convergence and stability of the neuro-fuzzy models will enable the reader to pursue their research career in cognitive engineering.

Management of Convergence in Innovation : Strategies and Capabilities for Value Creation Beyond Blurring Industry Boundaries
Throughout the past decade, the phenomenon of technological convergence has increasingly gained managerial attention. In this special form of technological change, the coming-together of previously distinct knowledge bases gives rise to the creation of new applications and business models. When such innovations emerge at the intersection of industries, the resulting creative destruction may exceed previously established industry boundaries. As a consequence, convergence does not only promise the creation of new value, but may imply significant disruptions to established industries. Based on investigating 26 firms within the ICT industry, this book highlights implications of the convergence phenomenon on firms’ innovation management practices, and derives strategic guidelines for building and sustaining business models beyond blurring industry boundaries.
Linear Differential Equations and Group Theory from Riemann to Poincaré
A study of how a particular vision of the unity of mathematics, often called geometric function theory, was created in the 19th century. The central focus is on the convergence of three mathematical topics: the hypergeometric and related linear differential equations, group theory, and on-Euclidean geometry. The text for this second edition has been greatly expanded and revised, and the existing appendices enriched with historical accounts of the Riemann–Hilbert problem, the uniformization theorem, Picard–Vessiot theory, and the hypergeometric equation in higher dimensions. The exercises have been retained, making it possible to use the book as a companion to mathematics courses at the graduate level.
Iterative Learning Control : Robustness and Monotonic Convergence for Interval Systems
This monograph studies the design of robust, monotonically-convergent iterative learning controllers for discrete-time systems. Two key problems with the fundamentals of iterative learning control (ILC) design as treated by existing work are: first, many ILC design strategies assume nominal knowledge of the system to be controlled and; second, it is well-known that many ILC algorithms do not produce monotonic convergence, though in applications monotonic convergence is often essential. Iterative Learning Control takes account of the recently-developed comprehensive approach to robust ILC analysis and design established to handle the situation where the plant model is uncertain. Considering ILC in the iteration domain, it presents a unified analysis and design framework that enables designers to consider both robustness and monotonic convergence for typical uncertainty models, including parametric interval uncertainties, iteration-domain frequency uncertainty, and iteration-domain stochastic uncertainty.
