Perhaps you should try some spelling variations:
associated operators » associated factors, dominated operators
associate editors » associated factors
associate editor » associate director, associated vector, associated factor
associate factor » associated factors, associated vector, associate director

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((associate editor) OR (associate editors))) OR (((associate factor) OR (associated operators)))).
• Adding a wildcard symbol may retrieve word variants: ((((associate editor) or (associate editors))) or (((associate factor) or (associated operators))))*.
