Perhaps you should try some spelling variations:
"social reproduction" » "sexual reproduction"
"social regulation" » "social relations", "social simulation", "capital regulation"
"local regulation" » "global regulation", "legal regulation", "neural regulation"

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: (("social reproduction") OR ((("social regulation") OR ("local regulation")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"social reproduction\") or (((\"social regulation\") OR (\"local regulation\"))))".
• Removing quotes may allow a broader search: (( social reproduction ) or ((( social regulation ) OR ( local regulation )))).
• Adding a wildcard symbol may retrieve word variants: (("social reproduction") or ((("social regulation") OR ("local regulation"))))*.
