Perhaps you should try some spelling variations:
social etats » social ethics
social agent » social agents, social agency, social agenda
etats model » etas model, rats model, beats model
social jet » social je, social jetlag
social act » social acts, social acl, social actor

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 etats model ) OR ( ((((social jet) OR (social agent))) OR (social act)) model )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( social etats model ) or ( ((((social jet) OR (social agent))) or (social act)) model ))".
• Adding a wildcard symbol may retrieve word variants: (( social etats model ) or ( ((((social jet) OR (social agent))) or (social act)) model ))*.
