This paper explores the mutual implication of critical realism and semiosis. Three key questions can be posed in this regard. 1 The first (discussed in Section II) concerns how far critical realism needs to include semiosis, provisionally defined as the intersubjective production of meaning, 2 in its more general approach to social relations, their reproduction and transformation. In exploring ...

Niche construction theory is a relatively new approach in evolutionary biology that seeks to integrate an ecological dimension into the Darwinian theory of evolution by natural selection. It is regarded by many evolutionary biologists as providing a significant revision of the Neo-Darwinian modern synthesis that unified Darwin's theory of natural and sexual selection with 20th century populatio...

This paper introduces a new approach dedicated to the Ontology Personalization. Inspired by works in Cognitive Psychology, our work is based on a process which aims at capturing the user-sensitive relevance of the categorization process, that is the one which is really perceived by the end-user. Practically, this process consists in decorating the Specialization/Generalization links (i.e. the i...

Design-based research studies are conducted as iterative implementationanalysis-modification cycles, in which emerging theoretical models and pedagogically plausible activities are reciprocally tuned toward each other as a means of investigating conjectures pertaining to mechanisms underlying content teaching and learning. Yet this approach, even when resulting in empirically effective educatio...

Collaborative tagging has been quickly gaining ground because of its ability to recruit the activity of web users into effectively organizing and sharing vast amounts of information. Here we collect data from a popular system and investigate the statistical properties of tag co-occurrence. We introduce a stochastic model of user behavior embodying two main aspects of collaborative tagging: (i) ...

The revolution will not be televised. But The Coming Insurrection (2009) was. Originally published in France in 2007, the small booklet, written by the anonymous Comité Invisible (Invisible Committee), was denounced as a manual for terrorism by the French government and became a key piece of evidence against nine activists arrested in a raid in the small commune of Tarnac who were allegedly pla...

Design principles are semiotic by nature. To design means to structure systems of signs in such a way as to make possible the achievement of human goals: communication (as a form of social interaction), engineering (as a form of applied technical rationality), business (as a form of shared efficiency), architecture, art, education, etcetera. Design comes about in an environment traditionally ca...

Already in the 1950s some were proclaiming the twentieth century the " psychoanalytic century. " As it happened, they were right. But to which psychoanalysis were they referring? For clearly there has never been one psychoanalysis, as scholars of various persuasions have noted. Even during Freud's life as a psychoanalyst, from 1896-1939, we find a multitude of possible psychoanalyses at work. F...
