Perhaps you should try some spelling variations:
structural regionalization » structural marginalization, structural realization, structural regularization
"structural functionalism" » "structural functional", "structural functions", "structure functionality"
structural functionality » structure functionality, structural functional, structural conditionality
"structure functional" » "structural functional", "structure function", "structure functions"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("structural functionalism") OR ("structure functional"))) OR ("((structural regionalization) or (structural functionality))")).
• Removing quotes may allow a broader search: (((( structural functionalism ) or ( structure functional ))) or ( ((structural regionalization) or (structural functionality)) )).
• Adding a wildcard symbol may retrieve word variants: (((("structural functionalism") or ("structure functional"))) or ("((structural regionalization) or (structural functionality))"))*.
