Attention Researchers!
A warning from the University of Hong Kong:
"According to the latest research results, the presence of simple hyphens in the titles of academic papers adversely affects the citation statistics, regardless of the quality of the articles. The phenomenon applies to all major subject areas. Thus, citation counts and journal impact factors, commonly used for professorial evaluations in universities worldwide, are unreliable."
