Chartered Association of Business Schools ('ABS'), United Kingdom: journal rankings range from 4* (highest) to 1* (lowest) (lowest). Many UK universities actively push researchers to publish exclusively in journals ranked 3 or above. Journal rankings range from A* (highest) to C (lowest) (lowest).
This implies that abstracts and business reports, for example, do not qualify as scientific publications. It should be noted that review articles do, of course, count, despite the fact that the definition's phrasing may not make this evident at first.
