Perhaps you should try some spelling variations:
"organization studies, economics sociology" » "organizational studies, economics sociology", "organization studies, economic sociology", "organization studies, economics ecology", "organization studies, economics sociological"
"organization studies, economics psychology" » "organizational studies, economics psychology", "organization studies, economic psychology", "organization studies, economics psychological", "organization studies, ecological psychology"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"organization studies, economics sociology\") OR (\"organization studies, economics psychology\"))".
• Removing quotes may allow a broader search: (( organization studies, economics sociology ) OR ( organization studies, economics psychology )).
• Adding a wildcard symbol may retrieve word variants: (("organization studies, economics sociology") OR ("organization studies, economics psychology"))*.
