The concentration of private power over media has been the subject of intense public debate around the world. Critics have long feared waves of mergers creating a handful of large media firms that would hold sway over public opinion and endanger democracy and innovation. But others believe with equal fervor that the Internet and deregulation have opened the media landscape significantly. How concentrated has the American information sector really become? What are the facts about American media ownership? In this contentious environment, Eli Noam provides a comprehensive and balanced survey of media concentration with a methodical, scientific approach. He assembles a wealth of data from the last 25 years about mass media such as radio, television, film, music, and print publishing, as well as the Internet, telecommunications, and media-related information technology. After examining 100 separate media and network industries in detail, Noam provides a powerful summary and analysis of concentration trends across industries and major media sectors. He also looks at local media power, vertical concentration, and the changing nature of media ownership through financial institutions and private equity. The results reveal a reality much more complex than the one painted by advocates on either side of the debate. They show a dynamic system that fluctuates around long-term concentration trends driven by changing economics and technology. Media Ownership and Concentration in America will be essential reading and a trove of information for scholars and students in media, telecommunications, IT, economics, and the history of business, as well as media industry professionals, business researchers, and policy makers around the world. Critics and defenders of media trends alike will find much that confirms and refutes their world view. But the next round of their debate will be shaped by the facts presented in this book.

Emerging scientific and industrial applications in today's world require significant computing power. Modern software tools are available for such platforms but are relatively complex and require the use of innovative programming models. One promising area in modern software design is the development, analysis, and implementation of algorithms and adaptive methods. These advancements in programming are promising but lack relevant research and understanding. Formal and Adaptive Methods for Automation of Parallel Programs Construction: Emerging Research and Opportunities is an essential reference source that solves the problem of the development of efficient models, methods, and tools for parallel programming automation based on the algebra of algorithms, term rewriting, and auto-tuning paradigms. The results of this book will help to further develop and improve existing research on design, synthesis, and optimization of sequential and parallel algorithms and programs. Featuring research on topics such as auto-tuning methods, graphics processing, and algorithmic language, this book is ideally designed for mathematicians, software engineers, data scientists, researchers, academicians, and students seeking coverage on developing tools for automated design and parallel programs.

Advances in Computers, the latest volume in the series published since 1960, presents detailed coverage of innovations in computer hardware, software, theory, design, and applications. In addition, it provides contributors with a medium in which they can explore their subjects in greater depth and breadth than journal articles usually allow. As a result, many articles have become standard references that continue to be of significant, lasting value in this rapidly expanding field.

Topics in Parallel and Distributed Computing provides resources and guidance for those learning PDC as well as those teaching students new to the discipline. The pervasiveness of computing devices containing multicore CPUs and GPUs, including home and office PCs, laptops, and mobile devices, is making even common users dependent on parallel processing. Certainly, it is no longer sufficient for even basic programmers to acquire only the traditional sequential programming skills. The preceding trends point to the need for imparting a broad-based skill set in PDC technology. However, the rapid changes in computing hardware platforms and devices, languages, supporting programming environments, and research advances, poses a challenge both for newcomers and seasoned computer scientists. This edited collection has been developed over the past several years in conjunction with the IEEE technical committee on parallel processing (TCPP), which held several workshops and discussions on learning parallel computing and integrating parallel concepts into courses throughout computer science curricula.

Model-driven Development for Embedded Software: Application to Communications for Drone Swarm describes the principles of model-oriented design used in the aeronautical field, specifically for the UAV (Unmanned Aerial Vehicle). The book focuses on designing an embedded system for drones to carry out ad hoc communication within a drone fleet. In this context, an original methodology for rapid prototyping of embedded systems is presented. This approach saves time for the verification and formal validation phases, contributing to certification of the Unmanned Aerial System (UAS). The book also addresses the more traditional verification phases that must be performed to verify accuracy of the system. This evaluation is carried out in simulation and by real experimentation. The various tools necessary for the implementation of this methodology are described to allow the reader to be able to implement independently. Finally, to illustrate the contribution of this original methodology, an example of embedded system development is presented in which the different phases of the methodology are explained to conceive, validate and test a new secure routing protocol developed for communications within a fleet of drones.
