The international New Math developments between about 1950 through 1980, are regarded by many mathematics educators and education historians as the most historically important development in curricula of the twentieth century. It attracted the attention of local and international politicians, of teachers, and of parents, and influenced the teaching and learning of mathematics at all levels—kindergarten to college graduate—in many nations. After garnering much initial support it began to attract criticism. But, as Bill Jacob and the late Jerry Becker show in Chapter 17, some of the effects became entrenched. This volume, edited by Professor Dirk De Bock, of Belgium, provides an outstandin...
Speech coding has been an ongoing area of research for several decades, yet the level of activity and interest in this area has expanded dramatically in the last several years. Important advances in algorithmic techniques for speech coding have recently emerged and excellent progress has been achieved in producing high quality speech at bit rates as low as 4.8 kb/s. Although the complexity of the newer more sophisticated algorithms greatly exceeds that of older methods (such as ADPCM), today's powerful programmable signal processor chips allow rapid technology transfer from research to product development and permit many new cost-effective applications of speech coding. In particular, low bit rate voice technology is converging with the needs of the rapidly evolving digital telecom munication networks. The IEEE Workshop on Speech Coding for Telecommunications was held in Vancouver, British Columbia, Canada, from September 5 to 8, 1989. The objective of the workshop was to provide a forum for discussion of recent developments and future directions in speech coding. The workshop attracted over 130 researchers from several countries and its technical program included 51 papers.

Sure, everyone gets sick sometimes, but do you realize that plenty of those folks also die slow, unpleasant deaths from diseases that stumped even the experts at top-notch (still privately run) hospitals? That’s right: There are plenty of illnesses that even physicians have never heard about. Nodding Disease, Alice in Wonderland Syndrome, and Cutaneous Horn (yes, you grow a horn) are all featured here in pithy, energetic entries. You won’t have to worry about socialized medicine if you have this book—even if your doc could see you within a month, you might die due to his ignorance. Lucky for you and your loved ones, Ian Landau (who has no medical training but is a hell of a researcher) includes: Descriptions of each disease Background and history How to diagnose yourself and others Suggested treatments Prevention methods The book is not for the faint of heart, as it probably could cause cardiac arrest. (And you ain’t coming back from that without Ian’s help.)
The New Geographies of Energy: Assessment and Analysis of Critical Landscapes is a pioneering collection of new geographic scholarship. It examines such vitally important research topics as energy dilemmas of the United States, large trends and patterns of energy consumption including China’s role, "peak oil", energy poverty, and ethanol and other renewable energy sourcing. The book offers advances in key emerging areas of energy research, each distinguished in the following sections: (i) geographic approaches to energy modeling and assessment; (ii) fossil fuel landscapes; (iii) the landscapes of renewable energy; (iv) landscapes of energy consumption; and (v) an overview of the new geographies of energy (Karl Zimmerer, Annals Nature-Society and Energy issue editor) and an essay on America’s oil dependency (Vaclav Smil, renowned energy geographer). In addition there is a specially commissioned book review. This book was published as a special issue of the Annals of the Association of American Geographers.
The 10th edition of the World Directory of Crystallographers and of Other Scientists Employing Crystallographic Methods is a revised and up-to-date edition of the World Directory and contains the current addresses, academic status and research interests of over 8000 scientists in 74 countries. It is produced directly from the regularly updated electronic World Directory database, which is accessible via the World-Wide Web. Full details of the database are given in an Annex to the printed edition.
The importance of small-scale fisheries for sustainable livelihoods and communities, food security, and poverty eradication is indisputable. With the endorsement of the ‘Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries’, FAO member states recognize that governments, civil society organizations, and research communities all have a role to play in helping small-scale fisheries achieve these goals. This book argues that policies targeting small-scale fisheries need to be based on a solid and holistic knowledge foundation, and support the building of governance capacity at local, national, and global levels. The book provides rich illustrations from around the world of why...
