The Cybersyn project has lately received increased attention. In this article, we study the local technical antecedents of Stafford Beer's Cybersyn project in Chile, particularly regarding Cybernetics and Systems ideas and local computing and networking developments. We show that the Cybersyn project in Chile was hosted by a rich intellectual environment that understood Cybernetics and Systems ideas; that it found a mature computer community and infrastructure whose high point was the State Computing Enterprise EMCO/ECOM, and an advanced networking experience whose (...) flagship was the automation of the State Bank that involved a pioneering network of teleprocess. In summary, this paper attempts to unveil the deep historical background over which the globally unique cybernetic experiment called Cybersyn flourished. (shrink)

The aim of this paper is to identify, given certain democratic normative standards regarding deliberation, some pros as well as cons of possible online deliberation designs due to variations in two key design dimensions: namely, asynchronicity and anonymity. In particular, we consider one crucial aspect of deliberative argumentation: namely, its reciprocity, which puts interaction centre stage to capture the back-and-forth of reasons. More precisely, we focus on two essential features of the deliberative interaction: namely, its listening widely and listening carefully. (...) We conclude that one sort of online deliberation that combines the two design features of anonymity and asynchronicity is likely to better promote the reciprocity required for democratic deliberation than both natural and designed offline deliberations and online simulations of them.

The paper gives a simple result on the existence of normal forms for the following equivalence relation between objects of a category: A∼B if and only if there are maps A→B and B→A , under the hypothesis that the category has epi-mono factorizations and each object has finitely many sub-objects and quotient-objects. Applications to algebra, logic, automata theory, databases are presented.

We review and discuss A. H. Louie’s book “More than Life Itself: A Reflexion on Formal Systems and Biology” from an interdisciplinary viewpoint, involving both biology and mathematics, taking into account new developments and related theories.
