Kevin,
I don't know if these specifically address your conception of
"sociocultural theory," but two excellent collections on Giddens' work are:
Clark, J., Modgil, C., & Modgil, S. (Eds.). (1990). _Anthony Giddens:
Consensus and controversy_. London: Falmer.
Held, D., & Thompson, J. B. (Eds.). (1989). _Social theory of modern
societies: Anthony Giddens and his critics_. Cambridge: Cambridge
University Press.
Hope these help out.
