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

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