Namazi MR, Fallahzadeh MK. n-index: A novel and easily-calculable parameter for comparison of researchers working in different scientific fields. Indian Journal of Dermatology, Venereology and Leprology 2010;76(3):229-230
A very simple and easily calculable index for comparison of researchers working in different fields is suggested. This is the n-index = researcher's h-index divided by the highest h-index of the journals of his/her major field of study (n is the first letter of Namazi, co-author of this article). This novel index can overcome the problem of unequal citations in different fields, as publications in certain disciplines are typically cited much more or much less than in others.
