Sommario/riassunto

This book is a MUST for everyone in and around the optics community!Fiber Optic Essentials provides professionals and students new to the field of fiber optics with a high-level knowledge of principles, theories and applications. This primer can also be used as a succinct overview of optics for those with some engineering and physics background. Individuals involved with optics in non-traditional capacities such as in marketing and legal departments will find this volume introduces basic concepts completely in an easy to read format.  Casimer and Carolyn DeCusatis

Sommario/riassunto

Much theorizing in language change research is made without taking into account dialect data. Yet, dialects seem to be superior data to build a theory of linguistic change on, since dialects are relatively free of standardization and therefore more tolerant of variant competition in grammar. In addition, as compared to most cross-linguistic and diachronic data, dialect data are unusually high in resolution. This book shows that the study of dialect variation has indeed the potential, perhaps even the duty, to play a central role in the process of finding answers to fundamental questions of the
