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