‘Nu’ citation index may bridge gap between productivity and impact metrics

Researchers propose a new citation index that balances productivity and impact in academic publishing. The h-index of citations was introduced in 2005 by physicist Jorge E. Hirsch. This index is defined simply as the maximum number h of an author’s published papers with at least h citations each. For example, h = 3 means that there are three papers with 3 or more citations, but if a fourth paper exists, it has fewer than four citations.
