Convergence proposes the enhancement of the Internet with a novel, content-centric, publish-subscribe service model based on the versatile digital item (VDI): a common container for all kinds of digital content, including digital representations of real-world resources. VDIs will serve the needs of the future Internet, providing a homogeneous method for handling structured information, incorporating security and privacy mechanisms. CONVERGENCE subsumes the following areas of research:
· definition of the VDI as a new fundamental unit of distribution and transaction;
· content-centric networking functionality to complement or replace IP-address-based routing;
· security and privacy protection mechanisms;
· open-source middleware, including a community dictionary service to enable rich semantic searches;
· applications, tested under real-life conditions.
This book shows how CONVERGENCE allows publishing, searching and subscribing to any content. Creators can publish their content by wrapping it and its descriptions into a VDI, setting rights for other users to access this content, monitor its use, and communicate with people using it; they may even update or revoke content previously published. Access to content is more efficient, as search engines exploit VDI metadata for indexing, and the network uses the content name to ensure users always access the copy closest to them. Every node in the network is a content cache; handover is easy; multicast is natural; peer-to-peer is built-in; time/space-decoupling is possible. Application developers can exploit CONVERGENCE's middleware and network without having to resort to proprietary/ad hoc solutions for common/supporting functionality. Operators can use the network more efficiently, better controlling information transfer and related revenues flows. Network design, operation and management are simplified by integrating diverse functions and avoiding patches and stopgap solutions.
Whether as a text for graduate students working on the future of the Internet, or a resource for practitioners providing e-commerce or multimedia services, or scientists defining new technologies, CONVERGENCE will make a valuable contribution to the future shape of the Internet.
'"Internet Communication and Qualitative Research" is a trailblazing introduction to data sources that will come to the fore in the new millennium. Its cogent discussion of the techniques, ethics and methods of analysis of Internet data should be read by every qualitative researcher' - David Silverman, Goldsmiths College. 'The internet is exploding with possibilities for conducting social research. Mann and Stewart offer the first in-depth consideration of the prospects and potentials for doing qualitative research on-line. This wide ranging, clearly-written book is essential reading for researchers working at the cutting edge of qualitative methodology' - James A. Holstein, Marquette University. 'This is e-scholarship. The book is a transformative project which brings the best skills of the old print scholarship to the cyberworld. The authors are no mere theoreticians - but hands-on net-users, who have made the imaginative leap to the dot.com world, and who have mapped the way for net research and researchers. The authors are pioneers in the realm of digit-crit - opening the way with their critical evaluation of the digital media and net research. They profile the skills required by the online researcher and evaluate the context in which they are used - in relation to privacy, security, ethics and legal considerations. They also take up issues of power; they explore the social and political implications of the digital media, (with specific reference to gender) and the role of the online researcher. An absolute must for cybercitizens and an indispensable guide for students, researchers, and knowledge workers in the dot.com world' - Dale Spender. 'Mann and Stewart have prized open the mysteries of on-line qualitative research. For those new to this methodology the technology review demystifies; the social science research ethics issues are re-addressed with reference to the on-line situation; methods of conducting online focus groups and interviews, in particular, are detailed. The tone is both analytical and practical with a host of techniques suggested. I recommend this accessible text for all qualitative researchers, both academic and practitioner' - Rehan Ul-Haq, University of Birmingham Business School. 'Here is the clear, useful guide to the Internet research needed by all of us interested in on-line relationships and research. The authors address such issues as ethics, confidentiality, the theory and practice of on-line research, and on-line power relationships (which will be of concern in distance learning plans and programs). A very valuable book' - Cheris Kramarae, Center for the Study of Women in Society, University of Oregon. 'Wonderful - 'beyond the software' and into on-line interaction to aid and abet our qualitative research. This book shines the light. Mann and Stewart are to be congratulated in offering qualitative researchers effective and authentic ways forward through electronic communication. I'll use and recommend it!' - Gilly Salmon, Centre for Information and Innovation, Open University Business School. 'Opens to view a whole new avenue for social research. Internet communication is the wave of the future. Mann and Stewart capture its potential with insight, caution, and consummate procedural skill. Pathbreaking in its area of research methodology! Students and researchers will be very pleased with its clarity and usefulness' - Jaber F Gubrium, Department of Sociology, University of Florida. 'The authors have produced a timely and stimulating publication with handy explanations of Internet terms and qualitative research applications. This work should be made readily available not only for reference to academics and practitioners of marketing, but also to those with a lay interest in it' - Professor Len Tiu Wright, De Montfort University. "Internet Communication and Qualitative Research" is the first textbook to examine the impact of Internet technology on qualitative research methods. Drawing on many pioneering studies using computer-mediated communication (CMC), the authors show how online researchers can employ Internet-based qualitative methods to collect rich, descriptive, contextually-situated data. They discuss the methodological, practical and theoretical considerations associated with such methods as: in-depth online interviewing, virtual focus groups, and participant observation in virtual communities. This is a comprehensive and practical guide that: reviews online research practice and basic Internet technology; looks in detail at the skills required by the online researcher; examines the ethical, confidentiality, security and legal issues involved in online research; considers the theoretical challenges surrounding data collected in a 'virtual venue'; and, addresses the social and cultural impact of researching online through a discussion of power, gender and identity issues in the virtual world. "Internet Communication and Qualitative Research" will be an indispensable guide for all students and researchers working in the digital age.
24/7 access to all kinds of material is one of the great benefits of the Internet .or is it? With the floodgates of the Web wide open, pornography is now readily available, literally at one's fingertips. While there have been studies conducted on internet pornography users, there have none until now on those that are exposed to the "second-hand" impact. This unprecedented book is daring study that provides a psychodynamic understanding of women's experiences of husbands who use Internet pornography. It examines the relationship between wives' issues of self-esteem and their lack of efficacy; it also explores the female psychosexual development and its impact on wives' experiences with their husbands. This book is the first to explore the impact on women married to Internet pornography users. As one of the first studies daring enough to address and explore this darker side of society, this book should be on the shelves of all scholars in cultural anthropology, psychology, sociology, and women's studies.
