  • 1 Umpleby Stuart Reconsidering Cybernetics
    UMPLEBY STUART RECONSIDERING CYBERNETICS The field of cybernetics attracted great attention in the 1950s and 1960s with its prediction of a Second Industrial Revolution due to computer technology. In recent years few people in the US have heard of cybernetics (Umpleby, 2015a, see Figures 1 and 2 at the end of Paper). But a wave of recent books suggests that interest in cybernetics is returning (Umpleby and Hughes, 2016, see Figure at the end of Paper). This white paper reviews some basic ideas in cybernetics. I recommend these and other ideas as a resource for better understanding and modeling of social systems, including threat and response dynamics. Some may claim that whatever was useful has already been incorporated in current work generally falling under the complexity label, but that is not the case. Work in cybernetics has continued with notable contributions in recent years. Systems science, complex systems, and cybernetics are three largely independent fields with their own associations, journals and conferences (Umpleby, 2017). Four types of descriptions used in social science After working in social science and systems science for many years I realized that different academic disciplines use different basic elements. Economists use measurable variables such as price, savings, GDP, imports and exports. Psychologists focus on ideas, concepts and attitudes. Sociologists and political scientists focus on groups, organizations, and coalitions. Historians and legal scholars emphasize events and procedures. People trained in different disciplines construct different narratives using these basic elements. One way to reveal more of the variety in a social system is to create at least four descriptions – one each using variables, ideas, groups, and events (See the figures and tables in Medvedeva & Umpleby, 2015).

  • 1 © Stafford Beer December 1992 WORLD in TORMENT a TIME
    ã Stafford Beer December 1992 WORLD IN TORMENT A TIME WHOSE IDEA MUST COME You will remember the beginning of humankind. Our first parents were quick to get themselves into trouble. They were expelled from the garden of Eden. I understand that Adam took Eve's hand, and said: 'My dear, we are living in a time of transition'. Perhaps people have always felt like that. We certainly do today. Have you ever tried to list the components of contemporary change? It is easy enough to cite the marvels of modern science and technology - how the computer, and television, and medical science have changed our lives. If you start with such matters, it becomes a 'profound insight' to observe that there has been a change in the rate of change. But that was obvious twenty to thirty years ago, for I was writing books about it then. Components of Contemporary Change Today, my list is different. At the top is the spectacular advance in human misery. I estimate that more human beings are enduring agony today than ever before; the number could be greater than the sum of sufferers throughout history. I speak of starvation and epidemic; war and terrorism; deprivation, exploitation, and physical torture. I repeat the word agony; I am not talking about 'hard times'. Second on my list is the collapse of the civilisation we have known in our lifetime. We are looking at the rubble that remains of two competing empires. Soviet communism has accepted its own demise; Western capitalism has not accepted it yet. But I am not making a forecast.

  • What Is a Complex System?
    What is a Complex System? James Ladyman, James Lambert Department of Philosophy, University of Bristol, U.K. Karoline Wiesner Department of Mathematics and Centre for Complexity Sciences, University of Bristol, U.K. (Dated: March 8, 2012) Complex systems research is becoming ever more important in both the natural and social sciences. It is commonly implied that there is such a thing as a complex system, different examples of which are studied across many disciplines. However, there is no concise definition of a complex system, let alone a definition on which all scientists agree. We review various attempts to characterize a complex system, and consider a core set of features that are widely associated with complex systems in the literature and by those in the field. We argue that some of these features are neither necessary nor sufficient for complexity, and that some of them are too vague or confused to be of any analytical use. In order to bring mathematical rigour to the issue we then review some standard measures of complexity from the scientific literature, and offer a taxonomy for them, before arguing that the one that best captures the qualitative notion of the order produced by complex systems is that of the Statistical Complexity. Finally, we offer our own list of necessary conditions as a characterization of complexity. These conditions are qualitative and may not be jointly sufficient for complexity. We close with some suggestions for future work. I. INTRODUCTION The idea of complexity is sometimes said to be part of a new unifying framework for science, and a revolution in our understanding of systems the behaviour of which has proved difficult to predict and control thus far, such as the human brain and the world economy.

  • Cybernetica-The Law of Requisite Variety
    The Law of Requisite Variety “The Principles of Cybernetica Web” at http://pespmc1.vub.ac.be/REQVAR.HTML The larger the variety of actions available to a control system, the larger the variety of perturbations it is able to compensate. Control or regulation is most fundamentally formulated as a reduction of variety: perturbations with high variety affect the system's internal state, which should be kept as close as possible to the goal state, and therefore exhibit a low variety. So in a sense control prevents the transmission of variety from environment to system. This is the opposite of information transmission, where the purpose is to maximally conserve variety. In active (feedforward and/or feedback) regulation, each disturbance D will have to be compensated by an appropriate counteraction from the regulator R. If R would react in the same way to two different disturbances, then the result would be two different values for the essential variables, and thus imperfect regulation. This means that if we wish to completely block the effect of D, the regulator must be able to produce at least as many counteractions as there are disturbances in D. Therefore, the variety of R must be at least as great as the variety of D. If we moreover take into account the constant reduction of variety K due to buffering, the principle can be stated more precisely as: V(E) ³ V(D) - V(R) - K Ashby has called this principle the law of requisite variety: in active regulation only variety can destroy variety. It leads to the somewhat counterintuitive observation that the regulator must have a sufficiently large variety of actions in order to ensure a sufficiently small variety of outcomes in the essential variables E.

Future of Cybernetics Appendix Glossary Bibliography Biographical Sketch Summary The most important initiator of cybernetics was Norbert Wiener (l894–1964) with his book “Cybernetics or Control and Communication in the Animal and the Machine”. The contribution of Warren S. McCulloch (1898–1969) may be compared to that of Wiener. Cybernetics UNESCOhas also had precursors such as– A. M.EOLSS Ampère who introduced the word cybernétique as well as B. Trentowski who did the same in Polish. H. Schmidt, S. Odobleja in the 1930s, and P. Postelnicu in the early 1940s recognized the general importance of the idea of negative feedback. SAMPLE CHAPTERS The basic concepts of cybernetics are negative feedback and information. A famous example of negative feedback is given by Watt’s governor, the purpose of which is to maintain the speed of the wheel of a steam engine, at a given value, despite perturbations. The theory of information, mainly due to Claude E. Shannon, gives a measure of the unexpectedness of a message carried by a signal. Other traits of cybernetics must be noted, such as the “principle of requisite variety” introduced by W.

  • Allostasis, Homeostats, and the Nature of Stress
    Stress, 2002 Vol. 5 (1), pp. 55–58 Allostasis, Homeostats, and the Nature of Stress DAVID S. GOLDSTEINa,* and BRUCE MCEWENb aClinical Neurocardiology Section, National Institute of Neurological Disorders and Stroke, NIH, 10/6N252, 10 Center Drive MSC-1620, Bethesda, MD 20892-1620, USA; bRockefeller University, New York, NY, USA (Received 2 February 2001; Revised 12 July 2001; In final form 22 August 2001) This essay continues discussion of a new formulation of homeostasis that uses the concepts of allostasis and homeostats. The new formulation moves beyond Cannon’s concept of “homeostasis,” which posits an ideal set of conditions for maintenance of the internal environment. The notion of allostasis recognizes that there is no single ideal set of steady-state conditions in life, and different stressors elicit different patterns of activation of the sympathetic nervous and adrenomedullary hormonal systems. Allostasis reflects active, adaptive processes that maintain apparent steady states, via multiple, interacting effectors regulated by homeostatic comparators—“homeostats.” “Allostatic load” refers to the consequences of sustained or repeated activation of mediators of allostasis. From the analogy of a home temperature control system, the temperature can be maintained at any of a variety of levels (allostatic states) by multiple means (effectors), regulated by the thermostat (homeostat). Allostatic load and risks of system breakdown increase when, for example, the front door is left open in the winter. Applying these notions can aid in understanding how acute and chronic stress can exert adverse health consequences via allostatic load. Keywords: Stress; Distress; Allostasis; Homeostasis; Homeostat CANNON AND “HOMEOSTASIS” of emergencies, activation of the sympathico-adrenal system would enhance survival.

  • Viable System Model As a Framework for Understanding
    The Viable System Model as a Framework for Understanding Organizations by Raúl Espejo and Antonia Gill Introducing the Model The Viable System Model (VSM) is not a new idea. Created by Stafford Beer over twenty years ago, it has been used extensively as a conceptual tool for understanding organizations, redesigning them (where appropriate) and supporting the management of change. Despite its successful application within numerous private and public sector organizations, however, the VSM is not yet widely known among the general management population. There are two main reasons for this. Firstly, the ideas behind the model are not intuitively easy to grasp; secondly, they run counter to the great legacy of thinking about organizations dating from the Industrial Revolution - a legacy that is only now starting to be questioned. To deal with the second point in more detail, organizations have been viewed traditionally as hierarchical institutions that operate according to a top-down command structure: strategic plans are formulated at the top and implemented by a cascade of instructions through the tiered ranks. It is now widely acknowledged that this modus operandi is too slow and inflexible to cope with the increasing rate of change and complexity surrounding most organizations. Technology developments have helped to usher in a new concept of a flatter, networked-type organization with a wider distribution of data to reach all those who actually perform the work - in real time. The ground is now fertile for viewing the organization in a new light. However, there is also much confusion about the nature of this new-style organization.

  • VARIETY in DESIGN
    VARIETY in DESIGN Ranulph Glanville Portsmouth School of Architecture King Henry I St Portsmouth PO1 2DY Hampshire, UK ABSTRACT It is argued that creativity might be amplified through the co-operative sharing of brain power (in contrast to Ashby’s amplification of intelligence by restricting attention to the problem). This argument is extended to the act of design (seen as the making of the new), where it is proposed that the nature of the computer is to encourage co-operative sharing because, by making perfect copies, it denies ownership. This, in turn, underpins the processes of collaging and transformation that so suit the computer. A means of using the computer is proposed in which both sharing and distortion are encouraged, so that the new may be made while the individual’s sense of creation and of origination is respected. Possible questions and difficulties are raised. Some are resolved.1 VARIETY Ross Ashby (1) invented the concept of Variety to help discriminate the number of states that a system takes from those that it might take. He showed that a control(ling) system, if it were to control the controlled system properly (ie, without inhibiting the potential of its activities) had to have at least as much variety as the system to be controlled (2). More recently, I have shown that the controlled and the controlling systems must in fact have the same variety (8). Ashby applied his understanding of variety to the amplification of intelligence (1). Since, he argued, the brain has limited (albeit large) variety, its effectiveness in solving problems (for that is how Ashby discussed behaving intelligently) can only be improved by restricting the problem area.

    Organization: Viable Systems Model The Viable System Model Trevor Hilder Cavendish Software Ltd. (Presentation v1.03 12-Jun-1995) © Cavendish Software Ltd. 1995, portions © Stafford Beer 1985 This presentation provides a brief introduction to Stafford Beer’s Viable System Model (VSM). Stafford Beer is one of the leading figures in the science of cybernetics, which concerns itself with the underlying laws which govern how organisms, machines and organizations maintain their identity, and fulfill their purposes within their environment. Cybernetics claims that there are underlying laws which apply equally to the manner in which the nervous system of an animal maintains control over its actions, to the way in which a species maintains itself within its ecosystem, and to how a corporation maintains its existence in its marketplace. The VSM provides a notation which can be applied by non- mathematicians to help them understand and apply these general laws. © Cavendish Software Ltd. 1995, portions © Stafford Beer 1985 1 Organization: Viable Systems Model Objective nTo provide a brief introduction to Stafford Beer’s Viable System Model uIts purpose uHow it can be used © Cavendish Software Ltd. 1995, portions © Stafford Beer 1985 Stafford Beer developed the VSM over a period of over thirty years as an aid to the practical process of diagnosing problems in human organizations, and helping to improve their functioning.

He believes that the science of cybernetics can be used to design organizations which fulfill these objectives.

Huge majestic waves roll into the bay and crash magnificently over the rocks, sparkling white against the green sea under a winter sun. It is for me a time of peace, a time to clear the head, a time to treasure. For after all, such times are rare events for today’s civilized man. We spend our days boxed in our houses, swarming in and out of office blocks like tribes of ants, crammed into trains, canned in aeroplanes, locked solid in traffic jams on the freeway. Our unbiblical concern for what we shall eat, what we shall drink, and what we shall put on is amplified and made obsessional by the pressure to consume—way, way beyond the natural need.
