Peirce’s system of philosophy can be applied to environmental communication issues. Prior to this he was a founding member of the Good Wood Advisory Centre, and a contributor to the Australian Good Wood Guide, now in its ni...

Recent advances in the study of networked systems have highlighted that our interconnected world is composed of networks that are coupled to each other through different “layers” that each represent one of many possible subsystems or types of interactions. Nevertheless, it is traditional to aggregate multilayer networks into a single weighted network in order to take advantage of existing tools...

In practical logic design circuits are built by composing certain types of gates. Each gate itself is a simple circuits with one, two or three inputs and one output, which implements an elementary logic function. These functions are called the generators. For the general purpose the set of generators is considered to be functionally complete, i.e., it is able to express any logic function under...

This paper combines aspects of formal concept analysis, Barwise & Seligman’s information flow theory and a Peircean notion of triadic signs. The goal of the paper is to formalize a model of communication that includes explicit, formal representations of signs, conceptual entities that are denoted by the signs and contexts in which the signs are used. Each triad of signs, conceptual entities and...

In Study 1, 54 3-, 6- and 9-month-old infants interacted with an adult stranger who engaged in a face-to-face (dyadic) exchange. Dyadic interaction was halted when the adult turned away to look at an object. In a Joint Attention condition, the adult alternated visual attention between the infant and the object, and in a Look Away condition she looked away at the object only. Infants gazed and s...

Triadic concept analysis (TCA) is an extension of formal concept analysis (dyadic case) which takes into account modi (e.g. time instances, conditions, etc.) in addition to objects and attributes. Thus instead of 2-dimensional binary tables TCA concerns with 3-dimensional binary tables. In our previous work we generalized TCA to work with grades instead of binary data; in the present paper we s...
