RISK AS SYSTEM ORGANIZATION INDEPENDENT COMPONENT OF AN INDIVIDUAL PURPOSEFUL ACTIVITY

An attempt to define purposeful activity.

An initial look at the term PU1-poseful activity suggests it would be difficult to define except in terms of the individual. Because purposeful activities are unique constructions for individuals, the term eludes definition as a conceptual whole. Elude, however, does not mean defy. To elude is to hide, to evade exposure. That the profession of occupational therapy has only recently attempted to...

‘‘Organization’’ as Setting Boundaries of Individual Development

‘Development’’ suggests that there is something that is developing, or changing over time. We can ask about temporal boundaries of that developmental process, asking when development begins or ends and whether it has defined stages along the way, for example. We can ask about spatial boundaries as well: where does the developing object start and end? For this article, I ask about the boundary d...

Topographic independent component analysis as a model of V1 organization and receptive fields

Independent component analysis (ICA) has been recently used as a model of natural image statistics and V1 simple cell receptive "elds. Here we show how to extend the ICA model to explain V1 topography as well. This is done by relaxing the independence assumption and ordering the basis vectors so that vectors with strong higher-order correlations are near each other. This is a new principle of t...
