Perhaps you should try some spelling variations:
"supply chain integration theories." » "supply chain integration theorems.", "supply chain integrationstheorie 2.", "supply chain integration theory."
"supply crowd integration efforts." » "supply crowd international efforts.", "supply crowd conservation efforts.", "supply grid integration efforts.", "supply rfid integration efforts.", "supply beyond integration efforts.", "supply growth integration efforts.", "supply cost integration efforts.", "supply from integration efforts."

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: "((\"supply chain integration theories.\") OR (\"supply crowd integration efforts.\"))~".
• Removing quotes may allow a broader search: (( supply chain integration theories. ) OR ( supply crowd integration efforts. ))~.
• Adding a wildcard symbol may retrieve word variants: (("supply chain integration theories.") OR ("supply crowd integration efforts."))*.
