Thanks Jeff!
The authors of this paper seem answering the question posed in another paper about the same topic:
“The disaster of the impact factor” where we can read the question:
“…Why such a biased tool continues to exist in Science?…”:
http://link.springer.com/article/10.1007%2Fs11948-014-9517-0
but Casadevall and Fang do not cite the source paper!
This is unethical!
Other information is also overlapping with this paper without proper citation!
Unethical and patronizing behavior from Casadevall and Fang?
