Web-enabled communication technologies are at the forefront of rapid change in education from the K-12 level through postgraduate education. The ascendancy of online learning environments has opened an array of opportunities and challenges, and has raised a formidable set of implications-in the pedagogical, economic, political, and other realms-that we have only begun to grasp, let alone fully manage.Online and Distance Learning: Concepts, Methodologies, Tools and Applications provides a comprehensive collection of case studies, empirical research, conceptual demonstrations, and best practices on Web-enabled learning technologies. This comprehensive, six-volume collection addresses all prominent aspects of online and distance learning, including information communication technologies applied to education, virtual classrooms, pedagogical systems, Web-based learning communities, library information systems, virtual universities, and numerous other topics. Collecting defining research in over 300 chapters from some 800 contributors representing more than 100 countries, Online and Distance Learning: Concepts, Methodologies, Tools and Applications enables libraries to provide a foundational reference to meet the information needs of researchers, educators, practitioners, administrators, and all other stakeholders in the online and distance learning context.

'A very practical text that provides professionals new to this arena with a good introduction to what they can expect to encounter in online work. The book contains numerous thought-provoking examples and exercises for those contemplating work in virtual arenas' - Terry Hanley, Lecturer in Counselling, University of Manchester. 'It's tempting to think that face-to-face experience translates straightforwardly to online work. But it doesn't. Jane Evans shows how many different aspects there are to counselling on-line! My advice would be, don't attempt it until you have worked through this book' - Professor Michael Jacobs, author of "Psychodynamic Counselling in Action". Counsellors - and other professionals who provide emotional support and guidance - are increasingly working online. The difference between online and face-to-face interaction with clients is vast and practitioners need to equip themselves with specialist knowledge and skills to ensure that they are being effective. "Online Counselling and Guidance Skills" is the first book to deal with the practicalities of this mode of working. It looks at how practitioners need to adapt their basic counselling skills to the online environment and guides them through the process of setting up, defining and maintaining a working relationship with a client within professional, ethical and legal boundaries. Case studies and extracts from online sessions show how the skills are put into practice, while practical exercises and points for further consideration help readers to develop their own knowledge and skills. Until now, books and articles have generally focused on the therapeutic work done by counsellors online. However, this book addresses people who use counselling skills in a wide range of contexts; including counselling, education, mental health, social care and careers guidance.
Since most of the problems arising in science and engineering are nonlinear, they are inherently difficult to solve. Traditional analytical approximations are valid only for weakly nonlinear problems and often fail when used for problems with strong nonlinearity. "Nonlinear Flow Phenomena and Homotopy Analysis: Fluid Flow and Heat Transfer" presents the current theoretical developments of the analytical method of homotopy analysis. This book not only addresses the theoretical framework for the method, but also gives a number of examples of nonlinear problems that have been solved by means of the homotopy analysis method. The particular focus lies on fluid flow problems governed by nonlinear differential equations. This book is intended for researchers in applied mathematics, physics, mechanics and engineering. Both Kuppalapalle Vajravelu and Robert A. Van Gorder work at the University of Central Florida, USA.
Henry Drummond (1851 -1897) was a Scottish evangelist, writer and lecturer. In 1877 he became lecturer on natural science in the Free Church College, which enabled him to combine all the pursuits for which he felt a vocation. His studies resulted in his writing Natural Law in the Spiritual World, the argument of which is that the scientific principle of continuity extends from the physical world to the spiritual. Before the book was published in 1883, an invitation from the African Lakes Company drew Drummond away to Central Africa. His character was full of charm. His writings were too nicely adapted to the needs of his own day to justify the expectation that they would long survive it, but only few men have exercised more religious influence in their own generation.
The function of a filter is to transform a signal into another one more suit- able for a given purpose. As such, filters find applications in telecommunica- tions, radar, sonar, remote sensing, geophysical signal processing, image pro- cessing, and computer vision. Numerous authors have considered deterministic and statistical approaches for the study of passive, active, digital, multidimen- sional, and adaptive filters. Most of the filters considered were linear although the theory of nonlinear filters is developing rapidly, as it is evident by the numerous research papers and a few specialized monographs now available. Our research interests in this area created opportunity for cooperation and co- authored publications during the past few years in many nonlinear filter families described in this book. As a result of this cooperation and a visit from John Pitas on a research leave at the University of Toronto in September 1988, the idea for this book was first conceived. The difficulty in writing such a mono- graph was that the area seemed fragmented and no general theory was available to encompass the many different kinds of filters presented in the literature. However, the similarities of some families of nonlinear filters and the need for such a monograph providing a broad overview of the whole area made the pro- ject worthwhile. The result is the book now in your hands, typeset at the Department of Electrical Engineering of the University of Toronto during the summer of 1989.
