Cybernetics Approach to Virtual Emotional Spaces Cybernetics Approach to Virtual Emotional Spaces An electrodermal activity actuated adaptive space Sayyed Amir Hossain Maghool1, Mitra Homolja2, Marc Aurel Schnabel3 1,2,3Victoria University of Wellington 1,3{sayyedamirhossain.maghool|marcaurel.schnabel}@vuw.ac.nz 2mitra.homolja@gmail. com In contrast to reductionist investigating of interrelation between emotion and architecture, we have proposed a new concept for creating an adaptive architecture system that employs biosensors and virtual reality (VR). We have generated a dynamic audio-visual Virtual Environment (VE) that has the potential of manipulating the emotional arousal level of the users measured via electrodermal activity (EDA) of skin. Much like the second-order cybernetics system, our simulations have actuators, sensors, and an adaptation mechanism, whereby participant's real-time biofeedback is interpreted and loops back into the simulation to moderate the user experience. The results of our preliminary test show that our system is capable of manipulating the emotional arousal level of the participants by using its dynamic VE.

  • What Is a Complex Adaptive System?
    PROJECT GUTS What is a Complex Adaptive System? Introduction During the last three decades a leap has been made from the application of computing to help scientists ‘do’ science to the integration of computer science concepts, tools and theorems into the very fabric of science. The modeling of complex adaptive systems (CAS) is an example of such an integration of computer science into the very fabric of science; models of complex systems are used to understand, predict and prevent the most daunting problems we face today; issues such as climate change, loss of biodiversity, energy consumption and virulent disease affect us all. The study of complex adaptive systems, has come to be seen as a scientific frontier, and an increasing ability to interact systematically with highly complex systems that transcend separate disciplines will have a profound affect on future science, engineering and industry as well as in the management of our planet’s resources (Emmott et al., 2006). The name itself, “complex adaptive systems” conjures up images of complicated ideas that might be too difficult for a novice to understand. Instead, the study of CAS does exactly the opposite; it creates a unified method of studying disparate systems that elucidates the processes by which they operate. A complex system is simply a system in which many independent elements or agents interact, leading to emergent outcomes that are often difficult (or impossible) to predict simply by looking at the individual interactions. The “complex” part of CAS refers in fact to the vast interconnectedness of these systems. Using the principles of CAS to study these topics as related disciplines that can be better understood through the application of models, rather than a disparate collection of facts can strengthen learners’ understanding of these topics and prepare them to understand other systems by applying similar methods of analysis (Emmott et al., 2006).

  • Adaptive Capacity and Traps

[online] URL: http://www.ecologyandsociety.org/vol13/iss2/art40/ Insight Adaptive Capacity and Traps Stephen R. Carpenter 1 and William A. Brock 1 ABSTRACT. Adaptive capacity is the ability of a living system, such as a social–ecological system, to adjust responses to changing internal demands and external drivers. Although adaptive capacity is a frequent topic of study in the resilience literature, there are few formal models. This paper introduces such a model and uses it to explore adaptive capacity by contrast with the opposite condition, or traps. In a social– ecological rigidity trap, strong self-reinforcing controls prevent the flexibility needed for adaptation. In the model, too much control erodes adaptive capacity and thereby increases the risk of catastrophic breakdown. In a social–ecological poverty trap, loose connections prevent the mobilization of ideas and resources to solve problems. In the model, too little control impedes the focus needed for adaptation. Fluctuations of internal demand or external shocks generate pulses of adaptive capacity, which may gain traction and pull the system out of the poverty trap. The model suggests some general properties of traps in social–ecological systems. It is general and flexible, so it can be used as a building block in more specific and detailed models of adaptive capacity for a particular region. Key Words: adaptation; allostasis; model; poverty trap; resilience; rigidity trap; transformation INTRODUCTION it seems empty of ideas, it will be abandoned or transformed into something else.

Dana Center at The University of Texas at Austin. Available at www.dcmathpathways.org/learn-about/emerging-issues-mathematics-pathways Copyright 2019 Chapter 6 Higher Education as a Complex Adaptive System: Considerations for Leadership and Scale Jeremy Martin The Charles A. Dana Center The University of Texas at Austin Abstract As state policies, economic pressures, and enrollment declines increase pressure on higher education systems to rapidly improve student outcomes in mathematics, many institutions have transformed the way they do business and have adopted mathematics pathways at scale. At the same time, many systems of higher education have struggled to move from piloting mathematics pathways to implementing reforms at a scale that supports every student’s success in postsecondary mathematics. Drawing on complexity science, this chapter presents a conceptual framework for leaders at all levels of higher education systems to design change strategies to adopt mathematics pathways principles at scale. How leaders think about the systems that they work in has material consequences for designing, implementing, and sustaining scaling strategies. The chapter offers a framework and recommendations for understanding higher education as a complex adaptive system and the role of strategic leadership in designing, implementing, and sustaining reforms at scale.

Christiansen Diane Larsen-Freeman Cornell University University of Michigan William Croft Tom Schoenemann University of New Mexico Indiana University Language has a fundamentally social function. Processes of human interaction along with domain-general cognitive processes shape the structure and knowledge of lan- guage. Recent research in the cognitive sciences has demonstrated that patterns of use strongly affect how language is acquired, is used, and changes. These processes are not independent of one another but are facets of the same complex adaptive system (CAS). Language as a CAS involves the following key features: The system consists of multiple agents (the speakers in the speech community) interacting with one another. This paper, our agreed position statement, was circulated to invited participants before a conference celebrating the 60th Anniversary of Language Learning, held at the University of Michigan, on the theme Language is a Complex Adaptive System. Presenters were asked to focus on the issues presented here when considering their particular areas of language in the conference and in their articles in this special issue of Language Learning.

  • The Immune System As a Complex System Eric Leadbetter [email protected] CMSC 491H Dr
    The Immune System as a Complex System Eric Leadbetter [email protected] CMSC 491H Dr. Marie desJardins Introduction The immune system is one of the most critical support systems in a living organism. The immune system serves to protect the body from harmful external agents. In order to accomplish its goal, the immune system requires both a detection mechanism that will discern harmful agents (pathogens) from self and neutral agents and an elimination mechanism to deal with discovered pathogens. Different levels of organismic complexity have increasingly complex detection and elimination mechanisms. The human immune system has a particular attribute that lends itself well to the study of complex systems: that of adaptation. The human immune system is able to “remember” which malicious agents have been encountered and subsequently respond more quickly when these agents are encountered again. In this way, the body can defend against infection much more efficiently. The problem with acquired immunity is that infectious agents are constantly evolving; thus, the immunological memory will lack a record for any newly evolved strains of disease. In addition to acquired immunity, humans have an innate immunity, which is the form of immune system that is also present in lower levels of organismic complexity such as simple eukaryotes, plants, and insects. The innate immune system serves as a primary response to infection by responding to pathogens in a non-specific manner. It promotes a rapid influx of healing agents to infected or injured tissues and serves to activate the adaptive immune system, among other things. A complex adaptive system is defined as such by the fact that the behavior of its agents change with experience as opposed to following the same rules ad infinitum.

  • Complex Adaptive Systems: Exploring the Known, the Unknown and the Unknowable
    BULLETIN (New Series) OF THE AMERICAN MATHEMATICAL SOCIETY Volume 40, Number 1, Pages 3{19 S 0273-0979(02)00965-5 Article electronically published on October 9, 2002 COMPLEX ADAPTIVE SYSTEMS: EXPLORING THE KNOWN, THE UNKNOWN AND THE UNKNOWABLE SIMON A. LEVIN Abstract. The study of complex adaptive systems, from cells to societies, is a study of the interplay among processes operating at diverse scales of space, time and organizational complexity. The key to such a study is an under- standing of the interrelationships between microscopic processes and macro- scopic patterns, and the evolutionary forces that shape systems. In particular, for ecosystems and socioeconomic systems, much interest is focused on broad scale features such as diversity and resiliency, while evolution operates most powerfully at the level of individual agents. Understanding the evolution and development of complex adaptive systems thus involves understanding how cooperation, coalitions and networks of interaction emerge from individual be- haviors and feed back to influence those behaviors. In this paper, some of the mathematical challenges are discussed. 1. Introduction The notion of complex adaptive systems has found expression in everything from cells to societies, in general with reference to the self-organization of complex enti- ties, across scales of space, time and organizational complexity. Much of our under- standing of complex adaptive systems comes from observations of Nature, or from simulations, and a daunting challenge is to summarize these observations mathe- matically. In essence, we need a statistical mechanics of heterogeneous populations, in which new types are continuously appearing through a variety of mechanisms, mostly unpredictable in their details.

The focus is on linear plants to facilitate understanding, but we also provide the tools necessary for many classes of nonlinear systems. We discuss practical issues encountered in making these systems stable and robust with respect to additive and multiplicative uncertainties. We discuss various perspectives on adaptive systems and their role in various fields. Finally, we present some of the ongoing research and expose problems in the field of adaptive control.

  • Managing Schools As Complex Adaptive Systems / Fidan & Balcı

Complex adaptive systems approach, introduced by the complexity theory, requires school administrators to develop new skills and strategies to realize their agendas in an ever-changing and complexifying environment without any expectations of stability and predictability. The results indicated that in this period administrators need to have basic skills such as (a) diagnosing patterns emerging from complexity, (b) manipulating the environment by anticipating potential patterns organizations may evolve into, (c) choosing organizational structures compatible with an ever-changing and complexifying environment and (d) promoting innovation to create and manage organizational changes. Although these skills enable administrators to reduce complexity into a manageable form to some extent, stakeholders’ having a common perspective regarding their schools and environments, and executing their activities in accordance with a shared vision are required to turn these skills into complexity management strategies. Keywords: Schools, complexity, complex adaptive systems, complexity management Introduction In the uncertain and constantly changing organizational Even scientists have not agreed on the definition of the environment of the information society, assumptions of term as complexity is a phenomenon arising from the order and predictability have gradually had a less part in interaction among numerous things (Johnson, 2007).
