Publisher's Synopsis
First Published in 1986. This book has two basic goals. The first goal is to present how information is formed, used, channelled, and delivered in a number of different contexts and systems with varying impacts. The second goal is to present these diverse applications within one framework so that there is continuity between the different subjects and chapters. The framework is behavioral systems, and so this book is also an attempt to further evolve and show the viability of this framework.
