This book proposes a new high level approach to programming that addresses the pragmatic issue of how a computation is distributed across a machine. Recent progress in VLSI provides massive parallelism but general purpose parallel computers remain elusive due to limited communications performance. This book proposes a new high level approach to programming that addresses the pragmatic issue of how a computation is distributed across a machine. The book's approach is based on functional programming and has significant advantages over existing comparable approaches, extending the domain of functional programming to include computer architectures in which communication costs are not negligible. It looks at how high-level functional programming languages can be used to specify, reason about, and implement parallel programs for a variety of multiprocessor systems, but in particular a class of loosely coupled multiprocessors whose operation can be described by a process network In these networks the nodes correspond to processes and the arcs to communications channels. A simple language called Caliban is described in which the functional program text is augmented with a declarative description of how processes are partitioned and mapped onto a network of processing elements. The notation gains expressive power by allowing these annotations to be generated by predicates defined in the functional language. Thus, common communications structures have simple and concise definitions as "network forming operators." The main objective of these annotations is to provide an abstract description of the process network specified by the program so that an efficient mapping of processes to processors can be carried out by the compiler. Functional Programming for Loosely Coupled Multiprocessors is included in the series Research Monographs in Parallel and Distributed Computing, copublished with Pitman Publishing.

The first collection in the area of mentoring that applies theory to real-world practice, research, programs, and recommendations from an international perspective In today’s networked world society, mentoring is a crucial area for study that requires a deep international understanding for effective implementation. Despite the immense benefits of mentoring, current literature on this subject is surprisingly sparse. The Wiley International Handbook of Mentoring fills the need for a comprehensive volume of in-depth information on the different types of mentoring programs, effective mentoring practices, and emerging practical and applicable theories. Based on sound research methodologies, this unique text presents original essays by experts from over ten different countries, demonstrating the ways mentoring can make a difference in the workplace and in the classroom; these experts have an understanding of mentoring worldwide having worked in mentoring in over forty countries. Each of the Handbook’s four sections—mentoring paradigms, practices, programs, and possibilities—include a final synthesis chapter authored by the section editors that captures the essence of the lessons learned, applies a global context, and recommends research avenues for further exploration. This innovative volume demonstrates how mentoring in any culture can help employees to complete tasks and advance in their positions, aid in socialization and assimilation in various settings, provide diverse groups access to resources and information, navigate through personalities, politics, policies, and procedures, and much more. Offers an inclusive, international perspective that supports moving mentoring into a discipline of its own and lays a theoretical foundation for further research Shows how emerging practical theories can be implemented in actual programs and various scenarios Examines a wide range of contemporary paradigms, practices, and programs in the field of mentoring, including a panorama of introspections on mentoring from international scholars and practitioners Includes historical and epistemological content, background information and definitions, and overviews of fundamental aspects of mentoring The Wiley International Handbook of Mentoring is an essential volume for a global readership, particularly teachers of mentoring courses, trainers, and researchers and practitioners in a variety of fields such as business, education, government, politics, sciences, industry, or sports.

The software development ecosystem is constantly changing, providing a constant stream of new tools, frameworks, techniques, and paradigms. Over the past few years, incremental developments in core engineering practices for software development have created the foundations for rethinking how architecture changes over time, along with ways to protect important architectural characteristics as it evolves. This practical guide ties those parts together with a new way to think about architecture and time.

The Web has not been hyped enough. That's the startling thesis of this one-of-a-kind book that's sure to become a classic work of social commentary. Just as Marshall McLuhan forever altered our view of broadcast media, Weinberger shows that the new medium of the Web is not only altering social institutions such as business and government but, more important, is transforming bedrock concepts of our culture such as space, time, the public, and even reality itself. Weinberger introduces us to denizens of this new world, among them Zannah, whose online diary turns self-revelation into play; Tim Bray, whose map of the Web reveals what's at the heart of the new Web space; and Danny Yee and Claudiu Popa, part of the new breed of Web experts we trust despite their lack of qualifications. Through stories of life on the Web, an insightful take on some familiar (and some unfamiliar) Web sites, and a wicked sense of humor, Weinberger puts the Web into the social and intellectual context we need to begin assessing its true impact on our lives. The irony, according to Weinberger, is that this new technology is more in tune with our authentic selves than is the modern world. Funny, provocative, and ultimately hopeful, Small Pieces Loosely Joined makes us look at the Web -- and at life -- in a new light. From Small Pieces Loosely Joined: The Web has sent a jolt through our culture, zapping our economy, our ideas about the sharing of creative works, and possibly even institutions such as religion and government. Why? How do we explain the lightning charge of the Web? If it has fallen short of our initial hopes and fears about its transformational powers, why did it excite those hopes and fears in the first place? Why did this technology hit our culture like a bolt from Zeus? Suppose -- just suppose -- that the Web is a new world we're just beginning to inhabit . . . If the Web is changing bedrock concepts such as space, matter, time, perfection, public, knowledge, and morality -- each a chapter of this book -- no wonder we're so damn confused. That's as it should be. The Web is enabling us to rediscover what we've always known about being human: we are connected creatures in a connected world about which we care passionately . . . If this is true, then for all of the over-heated, exaggerated, manic-depressive coverage of the Web, we'd have to conclude that the Web in fact has not been hyped enough.
