ABSTRACT

The environments of work and occupational activity should be attracted by praxiology and by the structural analysis of action. The notions of diversity in the nature of the components, of variety and praxiological fruitfiilness are all included in that of heterogeneity. Praxiogram brings out the laws which govern the assembling of acts or constitutive units. The fulfillment of the act would be prepared by the elaboration of a determining diagram projecting the proposed or acceptable rate of structural complexity. Both common and learned acceptations of the word "intricacy" relate to entanglement, structural complexity that is connections between elements which will only become apparent after close analysis, and for which proximity is not a determining criterion. The notion of frequent act seems to provide a good operative interpretation of the social-psychological notions of status and role. Grasping and Releasing have a strong capacity of implication. But Grasping is both a social-psychological and an ergonomic act.
