"urban development studies." » "urban development services.", "urban development strategies.", "urban development strategy."
"human development studies." » "human development services.", "human development strategies.", "human development strategy."
"_ development series." » "_ development services.", "_ development agencies.", "_ development africa."

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("urban development studies.") OR ("human development studies."))) or ("_ development series."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("urban development studies.") OR ("human development studies."))) OR ("_ development series.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"urban development studies.\") OR (\"human development studies.\"))) or (\"_ development series.\"))".
• Removing quotes may allow a broader search: (((( urban development studies. ) OR ( human development studies. ))) or ( _ development series. )).
• Adding a wildcard symbol may retrieve word variants: (((("urban development studies.") OR ("human development studies."))) or ("_ development series."))*.
