Perhaps you should try some spelling variations:
integration theories » integration theory, integration through, integration efforts
crowd integration » grid integration, trade integration, chain integration
creation effects » generation effects, treatment effects, selection effects
side creation » trade creation, firm creation
supply crowd » supply growth, supply cost, supply how

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 side creation effects. ) OR ( supply crowd integration theories. ))~".
• Adding a wildcard symbol may retrieve word variants: (( supply side creation effects. ) OR ( supply crowd integration theories. ))*.
