scientist's level

The scientist's level (Mitropoulos 2009) is an attempt to quantitatively break scientist's into broad categories of advancement based on a combination of their total citations and publications. It is expressed as Lv, where v represent the overall level and L the progress within v. Functionally, these values are logarithmic decompositions of the sum of citations and publications, such that v represents the integer value of the (base 10) logarithm of the sum (i.e., v = 0 when the sum is less than 10, v = 1 when the sum is between 10 and 99, v = 2 when the sum is between 100 and 999, etc.), and L is the integer value of the sum divided by 10v (i.e., if v = 2, L = 1 if the sum is between 100 and 199, L = 2 if the sum is between 200 and 299, etc.).

$$v=\text{floor}\left[\log\left(C^P + P\right)\right]$$$$L^v=\text{floor}\left(\frac{C^P + P}{10^v}\right)$$

L can be any integer from 1 to 9, while v will generally be an integer between 0 and 5 (a v of 6 would require > 1 million combined citations and publications).

Because of this structure and the limited possible values of these measures, one could readily combine these into a single value as,

$$\text{level}=v.L=v + \frac{L}{10}.$$
