In this discussion paper we argue that category theory may play a useful role in formulating, and perhaps proving, results in ergodic theory, topogical dynamics and open systems theory (control theory). As examples, we show how to characterize Kolmogorov–Sinai, Shannon entropy and topological entropy as the unique functors to the nonnegative reals satisfying some natural conditions. We also provide a purely categorical proof of the existence of the maximal equicontinuous factor in topological dynamics. We then show how to define open systems (that can interact with their environment), interconnect them, and define control problems for them in a unified way.

This article develops some novel extensions of the classical Tavistock model of organisational psychodynamics. The classical model privileges the emotion of anxiety as the primary trigger for psychosocial experiences in organisations. While this approach has been very generative, it has also been limiting, since there are several other important emotions that shape how people take up their work and their roles in organisations. The article shows how open systems theory and sociotechnical thinking emerge logically from the anxiety model by highlighting how organisations become functional, and work becomes satisfying. The article goes on to explore how desire as a feeling for the future, stimulates such feelings as danger, dread, and excitement. When these feelings become dispositive, they generate experiences associated with anxiety, and the primary risk, as well as the potential for developmental politics. Politics can be developmental rather than defensive when executives create settings where conflict is seen as transaction and rationality as an achievement. This article explores these issues through the use of case vignettes in the public domain, including a skunk works project in Data General, and leadership struggles and strategy dilemmas in Apple, IBM, and Polaroid.
