Living Control Systems


Book Description

Selected papers of William T. Powers: 22 articles and papers published here for the first time. This second in the Living Control Systems series underscores the potential of control theory to revolutionize the life sciences, in particular psychology... where, indeed, the theory found its most responsive audience. Powers makes the case for testable models in the tradition of scientific integrity, as the means for developing a genuine science of living control systems. Also included, selected published works on Living Control Systems, 1989-1991.




The Interdisciplinary Handbook of Perceptual Control Theory


Book Description

Interdisciplinary Handbook of Perceptual Control Theory Volume II: Living in the Loop brings together the latest research, theory, and applications from W. T. Powers' Perceptual Control Theory (PCT) that proposes that the behavior of a living organism lies in the control of perceived aspects of both itself and its environment. Sections cover theory, the application of PCT to a broad range of disciplines, why perceptual control is fundamental to understanding human nature, a new way to do research on brain processes and behavior, how the role of natural selection in behavior can be demystified, how engineers can emulate human purposeful behavior in robots, and much more. Each chapter includes an author biography to set the context of their work within the development of PCT. - Presents case studies that show how PCT can be applied in different disciplines - Illustrates the Test for the Controlled Variable (TCV) and the construction of functional models as fruitful alternatives to mainstream experimental design when studying behavior - Shows how theory illuminates structure and functions in brain anatomy - Compares and contrasts PCT with other contemporary, interdisciplinary theories

Control Systems Theory with Engineering Applications


Book Description

Dynamics systems (living organisms, electromechanical and industrial systems, chemical and technological processes, market and ecology, and so forth) can be considered and analyzed using information and systems theories. For example, adaptive human behavior can be studied using automatic feedback control. As an illustrative example, the driver controls a car changing the speed and steer ing wheels using incoming information, such as traffic and road conditions. This book focuses on the most important and manageable topics in applied multivariable control with application to a wide class of electromechanical dynamic systems. A large spectrum of systems, familiar to electrical, mechanical, and aerospace stu dents, engineers, and scholars, are thoroughly studied to build the bridge between theory and practice as well as to illustrate the practical application of control theory through illustrative examples. It is the author's goal to write a book that can be used to teach undergraduate and graduate classes in automatic control and nonlin ear control at electrical, mechanical, and aerospace engineering departments. The book is also addressed to engineers and scholars, and the examples considered allow one to implement the theory in a great variety of industrial systems. The main purpose of this book is to help the reader grasp the nature and significance of multivariable control.




Living Systems


Book Description

The use of innovative new materials is an important trend in landscape architecture today. These materials include biodegradable geotextiles, super-absorbent polymers, and plants that react to changing soil conditions. This book presents the available materials and technologies in the context of practical applications.




Engineering and Living Systems


Book Description

This book outlines for the first time a sound plan for interrelating the physical and engineering sciences and mathematics with biology and medicine. The walls of narrowing specialization that have kept these disciplines apart are broken down. The proposed program points up the need for an administrative structure to aid the flow of concepts, ideas, knowledge, and technology among those concerned, both within and without the university. The kinds of experts needed to bridge the existing gap between the two groups of disciplines are defined. Educational programs are outlined for full-time specialists, research participants, and practitioners in both engineering and medicine. A careful description is given of the stepwise process, including interaction with industry to apply development in the engineering sense to biology and medicine. A detailed example of the application of systems analysis and operations research to the development of a specific medical care program is also included. This book is a distillate of the general principles learned during the exploration of a joint program between Harvard University and the Massachusetts Institute of Technology, which was summarized by the authors in a Report to the National Academy of Engineering. The authors recognize the impossibility of providing on their own the authoritative grasp necessary to provide specific recommendations for the future in the many field comprised by engineering and living systems. Cooperation was obtained of outstanding experts on the two faculties, who prepared sixteen task group reports under the following headings: artificial internal organs; bioengineering curricula; biological control systems; continuing education; diagnostic instrumentation; diagnostic processes; image processing and visualization techniques; medical care microsystems; neurophysiology; organ and cell culture and storage; physiological monitoring; physiological systems analysis; regionalization of health services (macrosystems); sensory aids; skeletal prostheses; and subcellular engineering. The task group reports, included in this book, provide the documentation for the general conclusions of the authors. This book supplements existing medical programs with a new research approach to increase fundamental knowledge, and points the way to better medical care through more efficient application of engineering, technology, and systems development.




A Living Systems Theory of Vocational Behavior and Development


Book Description

The Living Systems Theory of Vocational Behavior and Development (LSVD) explains and illustrates the processes by which individuals construct their work experiences, vocational pathways and career patterns through episodes of interaction with affordances they recognize within their contexts, and how counseling can facilitate those processes. The LSVD was created by combining the scientifically based systems theory that explicates the dynamics of all aspects of human functioning and development, called Humans as Self-Constructing Living Systems, with important ideas about vocational behavior and development. The resulting integrative theory represents the individual person as a dynamic, self-directing and self-constructing entity, i.e., a living system. Behavior Episodes (BEs) are the fundamental, person-in-context, dynamic units of analysis that serve as the “building blocks” by which individuals construct and retain their experiences in patterns that can be reactivated to facilitate future BEs. The book describes how individuals’ history of satisfying BEs and their current activities provide the means by which vocational and career counselors can assist them to create satisfying vocational pathways. It also describes for researchers how new, non-linear, person-centered, quantitative and qualitative research methods can be used to analyze BE patterns to advance understanding of person-level processes that play key roles in individuals’ vocational behavior and development. The LSVD was designed to be not just an integrative framework for the field of career development, but also to reconnect the field to related areas such as human resources and industrial-organizational psychology and to the range of human sciences that have already embraced a living systems theoretical model.




Making Sense of Behavior


Book Description

Making Sense of Behavior is the long-anticipated work on Perceptual Control Theory (PCT) by the originator written for the general reader in nontechnical language. From the author: "This is a book about human nature, as we try to guess about it by watching human behavior. It's about a particular theory that seems to fit a great deal of what we see people doing and a great deal of our own private experience. A lot of people think that this is a pretty good theory. But my object in this book is not to persuade you that the theory is right, either by itself or by comparison with other theories. My main objective is to tell you what the theory is and why it has been constructed as it is. I will tell you of the observations that I have thought needed an explanation, and of how this theory appears to explain them. You can decide for yourself whether the theory and the observations go together, and are important."




Biological Processes in Living Systems


Book Description

Biological Processes in Living Systems is the fourth and final volume of the Toward a Theoretical Biology series. It contains essays that deal in detail with particular biological processes: morphogenesis of pattern, the development of neuronal networks, evolutionary processes, and others. The main thrust of this volume brings relevance to the general underlying nature of living systems. Faced with trying to understand how the complexity of molecular microstates leads to the relative simplicity of phenome structures, Waddington-on behalf of his colleagues-stresses on the structure of language as a paradigm for a theory of general biology. This is language in an imperative mood: a set of symbols, organized by some form of generative grammar, making possible the conveyance of commands for action to produce effects on the surroundings of the emitting and the receiving entities. "Biology," he writes, "is concerned with algorithm and program." Among the contributions in this volume are: "The Riemann-Hugoniot Catastrophe and van der Waals Equation," David H. Fowler; "Differential Equations for the Heartbeat and Nerve Impulse," E. Christopher Zeeman; "Structuralism and Biology," Rene Thom; "The Concept of Positional Information and Pattern Formation," Lewis Wolpert; "Pattern Formation in Fibroblast Cultures," Tom Elsdale; "Form and Information," C. H. Waddington; "Organizational Principles for Theoretical Neurophysiology," Michael A. Arbib; "Stochastic Models of Neuroelectric Activity," Jack D. Cowan. Biological Processes in Living Systems is a pioneering volume by recognized leaders in an ever-growing field.
