Sommario/riassunto

This text provides an overview of bi- and multilingualism as a worldwide phenomenon. It features comprehensive discussions of many of the linguistic, social, political, and educational issues found in an increasingly multilingual nation and world. To this end, the book takes the Chicano-Latino community of Southern California, where Spanish-English bilingualism has over a century and a half of history, and presents a detailed case study, thereby situating the community in a much broader social context. Spanish is the second most-widely spoken language in the U.S. after English, yet, for the mo

Sommario/riassunto

Optical Fiber Telecommunications VI (A&B) is the sixth in a series that has chronicled the progress in the R&D of lightwave communications since the early 1970's. Written by active authorities from academia and industry, this edition brings a fresh look to many essential topics, including devices, subsystems, systems and networks. A central theme is the enabling of high-bandwidth communications in a cost-effective manner for the development of customer applications. These volumes are an ideal reference for R&D engineers and managers, optical systems implementers, university researchers and...
