  • 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).

  • Environmental Influences: Family Systems Theory
    Environmental Influences: Family Systems Theory Family Systems Theory provides a broad and comprehensive mechanism for understanding the core aspects of the Performance Competence Lifespan Framework — quality of life, member- ship, and a personal sense of competence. It also focuses on the most important component of environmental influences—home and family. From birth, a child’s Quality of Life is directly influ- enced by the kind of care, support, stimulation and education he or she receives from family mem- bers in the home. As infants begin to develop secure attachments with significant others, particu- larly family members, they begin to establish themselves as members of the first and most basic unit of society—the family, which forms the foundation for secure Membership in other groups throughout life. The infant begins to develop a Personal Sense of Competence when his mother responds consistently to his distress, when he takes his first step or says his first word, or when his father praises him for using the toilet. These early beginnings, then, are at the core of what each individual child will come to know and be able to do. As the PC Framework indicates, there are multiple environmental influences on performance and competence, but the family is the first and most important. The influence of family members on one another is not simple, but complex; it is not one-way, but reciprocal. The family, like a mechanical system, is made up of multiple parts that are interdependent. When one part does not function well, all other parts are impacted. Further, the family interacts with other systems, includ- ing those that provide direct services to the child—child care/preschools, schools and community agencies—and each system affects the other.

  • Emergence in Psychology: Lessons from the History of Non-Reductionist Science
    Paper Human Development 2002;45:2-28 Human Development Emergence in Psychology: Lessons from the History of Non-Reductionist Science R. Keith Sawyer Washington University, St.louis, Mo., USA KeyWords Cognitive science. Emergence. History. Reductionism. Socioculturalism Abstract Theories of emergence have had a longstanding influence on psychological thought. Emergentism rejects both reductionism and holism; emergentists are scientific materialists, and yet argue that reductionist explanation may not always be scientifically feasible. I begin by summarizing the history of emergence in psy- chology and sociology, from the mid-19th century through the mid-20th century. I then demonstrate several parallels between this history and contemporary psy- chology, focusing on two recent psychological movements: socioculturalism and connectionist cognitive science. Placed in historical context, both sociocultural ism and connectionism are seen to be revivals of 19th and early 20th century emergen- tism. I then draw on this history to identify several unresolved issues facing socio- culturalists and connectionists, and to suggest several promising paths for future theory. Copyright @ 2002 S. Karger AG, Base! 1. Introduction Emergentism is a form of materialism which holds that some complex natural phe- nomena cannot be studied using reductionist methods.

  • Adaptation of Elaborated Feedback in E-Learning
    Adaptation of Elaborated Feedback in e-Learning Ekaterina Vasilyeva1,2, Mykola Pechenizkiy2, and Paul De Bra2 1 Department of Computer Science and Information Systems, University of Jyväskylä, P.O. Box 35, 40351 Jyväskylä, Finland 2 Department of Mathematics and Computer Science, Eindhoven University of Technology, P.O. Box 513, 5600MB Eindhoven, the Netherlands {e.vasilyeva,m.pechenizkiy}@tue.nl, [email protected] Abstract. Design of feedback is a critical issue of online assessment develop- ment within Web-based Learning Systems (WBLSs). In our work we demon- strate the possibilities of tailoring the feedback to the students’ learning style (LS), certitude in response and its correctness. We observe in the experimental studies that these factors have a significant influence on the feedback prefer- ences of students and the effectiveness of elaborated feedback (EF), i.e. stu- dents’ performance improvement during the test. These observations helped us to develop a simple EF recommendation approach. Our experimental study shows that (1) many students are eager to follow the recommendations on ne- cessity to read certain EF in the majority of cases; (2) the students more often find the recommended EF to be useful, and (3) the recommended EF helped to answer related questions better. Keywords: feedback authoring, feedback personalization, online assessment. 1 Introduction Online assessment is an important component of modern education. Nowadays it is used not only in e-learning for (self-)evaluation, but also tends to replace or comple- ment traditional methods of formal evaluation of the student’s performance in blended learning. Feedback is usually a significant part of the assessment as students need to be in- formed about the results of their (current and/or overall) performance.

  • 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.

    Massachusetts Institute of Technology Department of Electrical Engineering and Computer Science 6.243j (Fall 2003): DYNAMICS OF NONLINEAR SYSTEMS by A. Megretski Lecture 13: Feedback Linearization1 Using control authority to transform nonlinear models into linear ones is one of the most commonly used ideas of practical nonlinear control design. Generally, the trick helps one to recognize “simple” nonlinear feedback design tasks. 13.1 Motivation and objectives In this section, we give a motivating example and state technical objectives of theory of feedback linearization. 13.1.1 Example: fully actuated mechanical systems Equations of rather general mechanical systems can be written in the form M (q(t))¨q(t) + F (q(t); q˙(t)) = u(t); (13.1) where q(t) 2 Rk is the position vector, u(t) is the vector of actuation forces and torques, F : Rk £ Rk 7! Rk is a given vector-valued function, and M : Rk 7! Rk£k is a given function taking positive definite symmetric matrix values (the inertia matrix). When u = u(t) is fixed (for example, when u(t) = u0 cos(t) is a harmonic excitation), analysis of (13.1) is usually an extremely difficult task. However, when u(t) is an unrestricted control effort to be chosen, a simple change of control variable u(t) = M (q(t))(v(t) + F (q(t); q˙(t))) (13.2) transforms (13.1) into a linear double integrator model q¨(t) = v(t): (13.3) 1Version of October 29, 2003 2 The transformation from (13.1) to (13.3) is a typical example of feedback linearization, which uses a strong control authority to simplify system equations.

  • Scalability, Resilience, and Complexity Management in Laminar Control of Ultra-Large Scale Systems
    Scalability, Resilience, and Complexity Management in Laminar Control of Ultra-Large Scale Systems Jeffrey Taft, PhD Paul De Martini Connected Energy Networks Resnick Institute Cisco Systems, Inc. California Institute of Technology Abstract Ultra-large scale control systems that are based on layered optimization decomposition and Network Utility Maximization (NUM) have structural properties and operational modes that givesuch control systems useful scalabilityand anti-fragile properties. We denote control architectures based on these principles as Laminar Control and we suggest that the structure so defined has properties such as layer-by-layer segmentation of control signal traffic, abstraction of local state into scalar signal flows, self-similarity of data flow patterns at each layer, and support for islanded operation and re-connection. While the underlying physical networks (such as power systems) and associated communication networks are not necessarily self-similar, the imposition of the Laminar Control paradigm allows the creation such a structure at the application node level. Consequently, instead of having a set of agents with randomly structured logical connections, the optimization nodes become hubs and furthermore,it may be possible to restrict peer-to-peer communication at any level in the hierarchy to delimited specifiable domains. State determination can be similarly partitioned so that domain state need not be shared globally. In combination, these properties can invest distributed control networks with three valuable characteristics: scalability of control system real time network communications, resilience of the logical control network, and complexity bounds. Introduction: Laminar Control Architecture and Data Flows Distributed and hierarchical control methods have been available for decades. In the case of electric power systems, some of these concepts have been used in portions of the grid, but not as an Ultra-Large Scale (ULS) control.
