Voice over Internet Protocol (VoIP) has recently evolved from a simple capability for transporting voice communications into a much more powerful technology capable of changing the way voice applications are constructed, delivered, marketed and sold. Whilst VoIP has clearly provided a focus for much debate within the telecommunications industry, there has been a clear gulf between hype and reality. However the questions now being asked have migrated from 'Will it work?' to 'What will the industry look like when it is delivered at scale?' In Voice over IP: systems and solutions, Richard Swale has brought together key contributors from within the BT Group and externally, to cover all of the important issues surrounding telephony over IP networks. This authoritative book examines VoIP as a technology and its consideration within the industry, the motivations for VoIP networks, a review of the status of the major components of a VoIP network and their development, and both current and emerging applications. VoIP technology blurs the boundaries between fixed, mobile and multimedia communications and the implications are explored and discussed. The primary market for this comprehensive book is telecommunications engineers and developers, service providers and regulators. However, all those with a technical or business interest in this rapidly developing area of communications technology will also find this book highly relevant.

As this comprehensive and multi-disciplinary anthology makes clear, virtuality has a pedigree that pre-dates the computer age and modern virtual worlds, a pedigree that can be traced back to classical mythology and beyond. Equally, the concept of virtuality is not the province of one field of study alone but is the foundation and driving force of many, both theoretical and applied. Our conceptualizations and applications of virtuality are multiple, as is shown across the nine sections of the book that move from philosophy to technologies and applications before returning to philosophy again for a discussion of the utopias and dystopias of virtuality. The almost 50 essays contained within range freely across subjects that include the potential of virtuality, ethics, virtuality and self, presence and immersion, virtual emotions, image, sound and literature, computer games, AI and A-Life, Augmented Reality and Real Virtuality, law and economics, medical and military applications, religion, and cybersex. Throughout, contributors discuss differences between virtuality, reality, and actuality, in debates filtered through the lenses of the disciplines represented here, and speculate on future directions. It is not at all clear that there are differences and, if such distinctions are to be found, the boundaries between virtuality, reality, and actuality continually shift as ideas, modes of organization, and behaviors constantly flow from one to the other regardless of direction. The Handbook presents no unified definition of virtuality to comfort the reader, rather a multiplicity of questions and approaches underpinned by provocative statements that should further fuel the debates surrounding our notions of virtuality.

Virtual texts have emerged within the realm of the Internet as the predominant means of global communication. As both technological and cultural artifacts, they embody and challenge cultural assumptions and invite new ways of conceptualizing knowledge, community, identity, and meaning. But despite the pervasiveness of the Internet in nearly all aspects of contemporary life, no single resource has cataloged the ways in which numerous disciplines have investigated and critiqued virtual texts. This bibliography includes more than 1500 annotated entries for books, articles, dissertations, and electronic resources on virtual texts published between 1988 and 1999.

Because of the multiple contexts in which virtual texts are studied, the bibliography addresses virtual communication across a broad range of disciplines and philosophies. It encompasses studies of the historical development of virtual texts; investigations of the many interdisciplinary applications of virtual texts and discussions of such legal issues as privacy and intellectual property. Entries are arranged alphabetically within topical chapters, and extensive indexes facilitate easy access.

With the advent of new technologies and governmental regulation, notably the Telecommunications Act of 1996, not only has the broadcast industry changed dramatically, but also the laws covering the management and its human resources. Executives must know and understand these changes to operate within the law and to make best use of their people. With careful attention to scholarly accuracy and the latest thinking, Scott's book approaches the crucial human resource problems in broadcasting with a hands-on awareness of what really goes on among broadcasting industry people and the organizations that depend on them. Scott writes for practitioners and provides the information they can use daily, supplying academic professionals and students of broadcasting management with an important resource.

Chapter 1 briefly describes the broadcast industry, with special attention to significant technological changes and regulations. Chapter 2 examines the standard regulatory challenges faced by broadcasters. Chapters 3 and 4 review the major management and motivational theories over the past 150 years. These theories are then critiqued and applied to current personnel problems. The section on broadcast ethics discusses moral and ethical frameworks to help managers make the right decisions. In Chapter 5, the duties of the human resource director are noted along with pertinent EEOC laws banning discrimination. Chapter 6 reviews the employment process, including interviewing, training, performance reviews, progressive discipline, and the proper, legal method to terminate an employee. Chapter 7 enumerates the duties and responsibilities of the programming area including the operations manager, chief engineer, program director, and other department heads. Types of radio and television programming are discussed along with effective scheduling strategies. The book concludes with Chapter 8, Sales, which includes discussions of the Arbitron and Nielsen ratings organizations, sales proposals, and duties of the sales personnel.

Towards a Digital Renaissance traces the excitement and optimism of the early internet, the outsider cyberpunk ethic and open access. But it also monitors the more complex but ultimately more commercialised online world of today, a world dominated by corporate business in which many feel that surveillance has become overwhelming. Jeremy Silver's involvement in various start-ups, both as CEO and investor, led to his leadership of Digital Catapult. Towards a Digital Renaissance examines the interplay between state and private financing in the digital sector. It also argues for the internet's potential to transition from a 'medieval' world of the GAFA big four (Google, Amazon, Facebook and Apple), closed and walled up like medieval city states, to a 'digital renaissance' based on the free exchange of ideas and an enabling metaverse made up of virtual reality and artificial intelligence that deepens our experience of reality rather than restricting or monitoring it.

Middleware Networks: Concept, Design and Deployment of Internet Infrastructure describes a framework for developing IP Service Platforms and emerging managed IP networks with a reference architecture from the AT&T Labs GeoPlex project. The main goal is to present basic principles that both the telecommunications industry and the Internet community can see as providing benefits for service-related network issues. As this is an emerging technology, the solutions presented are timely and significant. Middleware Networks: Concept, Design and Deployment of Internet Infrastructure illustrates the principles of middleware networks, including Application Program Interfaces (APIs), reference architecture, and a model implementation. Part I begins with fundamentals of transport, and quickly transitions to modern transport and technology. Part II elucidates essential requirements and unifying design principles for the Internet. These fundamental principles establish the basis for consistent behavior in view of the explosive growth underway in large-scale heterogeneous networks. Part III demonstrates and explains the resulting architecture and implementation. Particular emphasis is placed upon the control of resources and behavior. Reference is made to open APIs and sample deployments. Middleware Networks: Concept, Design and Deployment of Internet Infrastructure is intended for a technical audience consisting of students, researchers, network professionals, software developers, system architects and technically-oriented managers involved in the definition and deployment of modern Internet platforms or services. Although the book assumes a basic technical competency, as it does not provide remedial essentials, any practitioner will find this useful, particularly those requiring an overview of the newest software architectures in the field.

Hypertext/hypermedia systems and user-model-based adaptive systems in the areas of learning and information retrieval have for a long time been considered as two mutually exclusive approaches to information access. Adaptive systems tailor information to the user and may guide the user in the information space to present the most relevant material, taking into account a model of the user's goals, interests and preferences. Hypermedia systems, on the other hand, are `user neutral': they provide the user with the tools and the freedom to explore an information space by browsing through a complex network of information nodes. Adaptive hypertext and hypermedia systems attempt to bridge the gap between these two approaches. Adaptation of hypermedia systems to each individual user is increasingly needed. With the growing size, complexity and heterogeneity of current hypermedia systems, such as the World Wide Web, it becomes virtually impossible to impose guidelines on authors concerning the overall organization of hypermedia information. The networks therefore become so complex and unstructured that the existing navigational tools are no longer powerful enough to provide orientation on where to search for the needed information. It is also not possible to identify appropriate pre-defined paths or subnets for users with certain goals and knowledge backgrounds since the user community of hypermedia systems is usually quite inhomogeneous. This is particularly true for Web-based applications which are expected to be used by a much greater variety of users than any earlier standalone application. A possible remedy for the negative effects of the traditional `one-size-fits-all' approach in the development of hypermedia systems is to equip them with the ability to adapt to the needs of their individual users. A possible way of achieving adaptivity is by modeling the users and tailoring the system's interactions to their goals, tasks and interests. In this sense, the notion of adaptive hypertext/hypermedia comes naturally to denote a hypertext or hypermedia system which reflects some features of the user and/or characteristics of his system usage in a user model, and utilizes this model in order to adapt various behavioral aspects of the system to the user. This book is the first comprehensive publication on adaptive hypertext and hypermedia. It is oriented towards researchers and practitioners in the fields of hypertext and hypermedia, information systems, and personalized systems. It is also an important resource for the numerous developers of Web-based applications. The design decisions, adaptation methods, and experience presented in this book are a unique source of ideas and techniques for developing more usable and more intelligent Web-based systems suitable for a great variety of users. The practitioners will find it important that many of the adaptation techniques presented in this book have proved to be efficient and are ready to be used in various applications.

Databases have been designed to store large volumes of data and to provide efficient query interfaces. Semantic Web formats are geared towards capturing domain knowledge, interlinking annotations, and offering a high-level, machine-processable view of information. However, the gigantic amount of such useful information makes efficient management of it increasingly difficult, undermining the possibility of transforming it into useful knowledge.

The research presented by De Virgilio, Giunchiglia and Tanca tries to bridge the two worlds in order to leverage the efficiency and scalability of database-oriented technologies to support an ontological high-level view of data and metadata. The contributions present and analyze techniques for semantic information management, by taking advantage of the synergies between the logical basis of the Semantic Web and the logical foundations of data management. The book's leitmotif is to propose models and methods especially tailored to represent and manage data that is appropriately structured for easier machine processing on the Web.

After two introductory chapters on data management and the Semantic Web in general, the remaining contributions are grouped into five parts on Semantic Web Data Storage, Reasoning in the Semantic Web, Semantic Web Data Querying, Semantic Web Applications, and Engineering Semantic Web Systems. The handbook-like presentation makes this volume an important reference on current work and a source of inspiration for future development, targeting academic and industrial researchers as well as graduate students in Semantic Web technologies or database design.

With contributions by leading scientists in the field, this book gives the first comprehensive overview of the results of the seminal SmartKom project - one of the most advanced multimodal dialogue systems worldwide.

This volume explores the nature of the Internet's impact on civil society, addressing the following central questions: is the Internet qualitatively different from the more traditional forms of the media? has the Internet demonstrated real potential to improve civil society through a wider provision of information, an enhancement of communication between government and citizen, or via better state transparency? does the Internet pose a threat to the coherence of civil society as people are encouraged to abandon shared media experiences and pursue narrow interests? in authoritarian states, does the Internet function as a beacon for free speech or as another tool for propaganda?

The Internet has redefined how maps are used. No longer restricted to paper, maps are now transmitted almost instantly and delivered to the user in a fraction of the time required to distribute maps on paper. They are viewed in a more timely fashion. The Internet presents the map user with both a faster method of map distribution and different forms of mapping. This book provides an international perspective on this growing area of information dissemination.

Web search engines are not just indispensable tools for finding and accessing information online, but have become a defining component of the human condition and can be conceptualized as a complex behavior embedded within an individual's everyday social, cultural, political, and information-seeking activities. This book investigates Web search from the non-technical perspective, bringing together chapters that represent a range of multidisciplinary theories, models, and ideas.
