Could you post the citation for the Still and Costall article?
I've just recently started thinking about the relationship between Gibson's
notion of affordances as ecological relations between organisms and the
world, notions of activity as relational configurations of persons, tools,
and the world, and notions of the world as sociohistorically objectified
(e.g., Ilyenkov, Lektorsky). In my own work, I've been considering ways
that semiotic artifacts (like published texts and research data), the
existence of particular institutional forums for future publication, and
certain literate practices may work in conjuction to form semiotic
affordances that help constitute disciplinary genres. I'd be interested in
hearing from others thinking about these relationships.
