Perhaps you should try some spelling variations:
"structural conditionality" » "structural conditions"
"structural functionalism" » "structural functional", "structure functional", "structured functional"
"structural functions" » "structural functional", "structure functions", "structures 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 ("structural functions"))) OR ("structural conditionality")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"structural functionalism\") OR (\"structural functions\"))) or (\"structural conditionality\"))".
• Removing quotes may allow a broader search: (((( structural functionalism ) OR ( structural functions ))) or ( structural conditionality )).
• Adding a wildcard symbol may retrieve word variants: (((("structural functionalism") OR ("structural functions"))) or ("structural conditionality"))*.
