2.
cybernetics •The science of effective government •Communication and Control •Relations modelling •Autonomy •Self-organization •Cognition •The role of the observer systems •Artificial and Natural second-order cybernetics

3.
second-order cybernetics is about •Relational Concepts •Circular Processes •Goal-Directedness and Control •Cognition

4.
relational concepts variety constraint entropy information dynamics

5.
circular processes self-application self-organization •Attractors closure feedback cycles •Negative •Positive

6.
goal-directedness and control goal- mechanisms law of directedness of control requisite •Autopoietic & Allopoietic •Buffering variety Systems •V(E) >= V(D) - V(R) - K •Feedforward •Essential Variables •Feedback components control of control hierarchies systems

7.
Components of Control Systems system goal representation decision information processing perception action observed dynamics affected variables variables disturbances environment

8.
cognition requisite modelling knowledge relation •Increasing constraint •Endo-models •Selectivity on choosing •Observation, the world, the appropriate action and inaccurate predictions •Heuristic Knowledge learning and constructivist model building epistemology •Constructivism •Coherence •Learning •Invariance •Homeostasis •Social construction of reality

9.
insights •Modelling systems is a complicated activity when treated with rigor. But conceptually, it’s fascinating. •Second-order Cybernetics engages transdisciplinary approaches. •Informatics is derived in part from Cybernetics.inquiry & reflection •What is the cybernetic approach for HCI Design? •Does it make sense?
