In 1959, John L. Holland introduced a theory of vocational choices, which is still used today. It embraces a personality typology involving six models (widely known as the Holland Code, or RIASEC). Here in this new publication, readers will finally see Holland's previously unpublished autobiography and appreciate this antidote for imperfect secondary accounts of the theory.This long-awaited book provides counseling practitioners, counselor educators, researchers, vocational psychologists and students with: 1) a clear and concise understanding of the Holland Theory and its implications for practice, 2) a snapshot of John Holland's life-long effort to establish the efficacy of the theory, and 3) an appreciation for the life of an accomplished theoretician and researcher and his impact on the counseling profession.
We are confronted with emergent systems everywhere and Holland shows how a theory of emergence can predict many complex behaviours in art and science. This book will appeal to scientists and anyone interested in scientific theory.
Genetic algorithms are playing an increasingly important role in studies of complex adaptive systems, ranging from adaptive agents in economic theory to the use of machine learning techniques in the design of complex devices such as aircraft turbines and integrated circuits. Adaptation in Natural and Artificial Systems is the book that initiated this field of study, presenting the theoretical foundations and exploring applications. In its most familiar form, adaptation is a biological process, whereby organisms evolve by rearranging genetic material to survive in environments confronting them. In this now classic work, Holland presents a mathematical model that allows for the nonlinearity of...
In this very short introduction, John Holland presents an introduction to the science of complexity. Using examples from biology and economics, he shows how complexity science models the behaviour of complex systems.
There’s a special language that transcends time and space—a language that’s not constrained by the limitations of just words—but one that consists of signs, symbols, energy, and thought. A language that can only be heard when one truly listens. It’s the language of The Spirit Whisperer. In John Holland’s past books, he explained how he came to terms with, and learned to accept and embrace, his spiritual gifts as a psychic medium; and how "readers" could develop their own intuitive psychic abilities. In this book, John picks up the fascinating story of his personal journey of growth and development as one of the most respected practicing mediums today. This work chronicles his car...
New viral diseases are emerging continuously. Viruses adapt to new environments at astounding rates. Genetic variability of viruses jeopardizes vaccine efficacy. For many viruses mutants resistant to antiviral agents or host immune responses arise readily, for example, with HIV and influenza. These variations are all of utmost importance for human and animal health as they have prevented us from controlling these epidemic pathogens. This book focuses on the mechanisms that viruses use to evolve, survive and cause disease in their hosts. Covering human, animal, plant and bacterial viruses, it provides both the basic foundations for the evolutionary dynamics of viruses and specific examples of emerging diseases. - NEW - methods to establish relationships among viruses and the mechanisms that affect virus evolution - UNIQUE - combines theoretical concepts in evolution with detailed analyses of the evolution of important virus groups - SPECIFIC - Bacterial, plant, animal and human viruses are compared regarding their interation with their hosts
Provides a typology of six personality types: the realistic, investigative, artistic, social, enterprising and conventional; assesses their interactions within the working environment, including likely performance, and social and educational behaviour, and shows how they are likely to act in different environments. Affirms the usefulness of the classification when applied to specific occupations and suggests practical applications.
