Perhaps you should try some spelling variations:
structural functionalization » structure functionalization, structural regionalization, structural marginalization
structural conditionality » structural conditions
structural functionalized » structural functional, structure functionality, structure functional
"structural functionalism" » "structural functional", "structural functions", "structure functionality"
structural functionality » structure functionality, structural functional, structural rationality
natural functionalized » natural functional, dual functionalized, future functionalized

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 ("((((((structural functionalized) or (natural functionalized))) or (((structural functionality) OR (structural conditionality))))) or (structural functionalization))")).
• Removing quotes may allow a broader search: (( structural functionalism ) or ( ((((((structural functionalized) or (natural functionalized))) or (((structural functionality) OR (structural conditionality))))) or (structural functionalization)) )).
• Adding a wildcard symbol may retrieve word variants: (("structural functionalism") or ("((((((structural functionalized) or (natural functionalized))) or (((structural functionality) OR (structural conditionality))))) or (structural functionalization))"))*.
