Book Description
Computer-Mediated Communication Systems: Status and Evaluation synthesizes current knowledge about computerized conferencing systems, electronic mail, and office information-communication systems. It should be of interest both to students and researchers studying this new form of electronic communication and to organizations that are planning the installation of electronic mail or other computer-mediated communication systems and that need to be aware of the information gleaned from the studies presented here. The book is organized into four main sections, focusing on the following issues: (1) What are the important considerations in designing software or choosing a system from the many available options and capabilities? (2) What factors determine whether such systems are likely to be accepted or rejected? (3) What are the likely impacts of such systems upon the individuals, groups, and organizations which use them? It is not the economic costs and benefits, but the social problems and ""payoffs"" in the form of enhanced performance and organizational efficiency that should be the main considerations in deciding whether or not to use a computer-mediated communication system. (4) Given the conditional nature of many of the possible impacts, no system should be implemented without formal evaluation and feedback from users to guide the implementation. The major kinds of evaluational strategies that have been successfully employed are described in this book.

Book Description
There is acceptance of the need to understand the relationship between social factors, system design and system usage in the field of computer-mediated communication systems. This book shows how the social context is presented intentionally and unintentionally in the design of such systems.

Book Description
We depend on information and information technology (IT) to make many of our day-to-day tasks easier and more convenient. Computers play key roles in transportation, health care, banking, and energy. Businesses use IT for payroll and accounting, inventory and sales, and research and development. Modern military forces use weapons that are increasingly coordinated through computer-based networks. Cybersecurity is vital to protecting all of these functions. Cyberspace is vulnerable to a broad spectrum of hackers, criminals, terrorists, and state actors. Working in cyberspace, these malevolent actors can steal money, intellectual property, or classified information; impersonate law-abiding parties for their own purposes; damage important data; or deny the availability of normally accessible services. Cybersecurity issues arise because of three factors taken together - the presence of malevolent actors in cyberspace, societal reliance on IT for many important functions, and the presence of vulnerabilities in IT systems. What steps can policy makers take to protect our government, businesses, and the public from those would take advantage of system vulnerabilities? At the Nexus of Cybersecurity and Public Policy offers a wealth of information on practical measures, technical and nontechnical challenges, and potential policy responses. According to this report, cybersecurity is a never-ending battle; threats will evolve as adversaries adopt new tools and techniques to compromise security. Cybersecurity is therefore an ongoing process that needs to evolve as new threats are identified. At the Nexus of Cybersecurity and Public Policy is a call for action to make cybersecurity a public safety priority. For a number of years, the cybersecurity issue has received increasing public attention; however, most policy focus has been on the short-term costs of improving systems. In its explanation of the fundamentals of cybersecurity and the discussion of potential policy responses, this book will be a resource for policy makers, cybersecurity and IT professionals, and anyone who wants to understand threats to cyberspace.

Book Description
Computer and Communication Networks, Second Edition first establishes a solid foundation in basic networking concepts, TCP/IP schemes, wireless networking, Internet applications, and network security. Next, Mir delves into the mathematical analysis of networks, as well as advanced networking protocols. This fully-updated text thoroughly explains the modern technologies of networking and communications among computers, servers, routers, and other smart communication devices, helping readers design cost-effective networks that meet emerging requirements. Offering uniquely balanced coverage of all key basic and advanced topics, it teaches through extensive, up-to-date case studies, 400 examples and exercises, and 250+ illustrative figures. Nader F. Mir provides the practical, scenario-based information many networking books lack, and offers a uniquely effective blend of theory and implementation. Drawing on extensive experience in the field, he introduces a wide spectrum of contemporary applications, and covers several key topics that competitive texts skim past or ignore completely, such as Software-Defined Networking (SDN) and Information-Centric Networking.

Book Description
Computers, Commmunication, and Mental Models is a far-ranging, focused treatment of the cognitive and behavioural issues in computer-mediated communication, knowledge representation and computer-supported co- operative work. It is also an argued development of the theoretical bases for treating computerized tools as intermediaries in the communication of mental maps between tool builders and users. Empirical trails are reported in detail sufficient for representation, in computer-based instruction, fractal dimensions of cognitive mapping and group decision support. The book is a collection of multidisciplinary papers which each shed light on the complex interactions between users and systems architects, via a common medium: computerized tools.
