Reference citations are needed for any statement in your proposal which is not of common knowledge and that requires information on the source. Focus on the few most relevant and most recent references, preferably those of international research journals. Avoid “grey” literature, text books and online or web references.
Some rules when citing references in the proposal text document:
- Single author publications: “author (year)” or “(author, year)”.
