The implementation of an Enterprise Portal is more of an art than a science. This is true due to the fact that each organization is different with respect to priorities, fiscal issues, culture, etc. To this end, implementing an Enterprise Portal in an organization is a highly customized process that cannot be churned out in a mass-production fashion. That being said, this book will highlight some of the core processes that are similar throughout companies; how they are implemented is where the customization part comes in.

The study of the genetic basis for evolution has flourished in this century, as well as our understanding of the evolvability and programmability of biological systems. Genetic algorithms meanwhile grew out of the realization that a computer program could use the biologically-inspired processes of mutation, recombination, and selection to solve hard optimization problems. Genetic and evolutionary programming provide further approaches to a wide variety of computational problems. A synthesis of these experiences reveals fundamental insights into both the computational nature of biological evolution and processes of importance to computer science. Topics include biological models of nucleic acid information processing and genome evolution; molecules, cells, and metabolic circuits that compute logical relationships; the origin and evolution of the genetic code; and the interface with genetic algorithms and genetic and evolutionary programming.

A Web portal is a special web site designed to act as a gateway giving convenient access to other related sites. This book investigates the various types of portals and describes how they can be used in business applications. After considering the nature of portals, the book describes the first general portals like Yahoo, and how they came into being. Portals are used in businesses of all types and sizes and this book discusses how portals can be used in large business corporations as well as small to medium enterprises. Web portals have increasing importance to marketers as, by their nature, they retain their users who must return to them frequently. They also provide a useful means of making information and knowledge readily available in a convenient form to authorised users. This book covers a wide range of issues relating to the use of portals in business.

This book, written for the general reader, explores the fundamental issues concerning the nature of time and space, and quantum mechanics. It shows how physics and philosophy work together to answer some of the deepest questions ever asked about the world.

"This volume will appeal to a wide array of readers, from novices to those already working in the field. Recommended for all collections." --CHOICE "Reference literature has been hard put to keep pace with its (distance learning) changes so the appearance of an Encyclopedia is most welcome. Recommended for academic and public libraries." --LIBRARY JOURNAL In today′s fast-paced world, with multiple demands on time and resources as well as pressures for career advancement and productivity, self-directed learning is an increasingly popular and practical alternative in continuing education. The Encyclopedia of Distributed Learning defines and applies the best practices of contemporary continuing education designed for adults in corporate settings, Open University settings, graduate coursework, and in similar learning environments. Written for a wide audience in the distance and continuing education field, the Encyclopedia is a valuable resource for deans and administrators at universities and colleges, reference librarians in academic and public institutions, HR officials involved with continuing education/training programs in corporate settings, and those involved in the academic disciplines of Education, Psychology, Information Technology, and Library Science. Sponsored by The Fielding Graduate Institute, this extensive reference work is edited by long-time institute members, bringing with them the philosophy and authoritative background of this premier institution. The Fielding Graduate Institute is well known for offering mid-career professionals opportunities for self-directed, mentored study with the flexibility of time and location that enables students to maintain commitments to family, work, and community. The Encyclopedia of Distributed Learning includes over 275 entries, each written by a specialist in that area, giving the reader comprehensive coverage of all aspects of distributed learning, including use of group processes, self-assessment, the life line experience, and developing a learning contract.
