Our findings have policy implications, because current measures of citation-based impact, from IF to Hirsch index (4, 17), are frequently integrated in reward procedures, the assignment of research grants, awards, and even salaries and bonuses (30), despite their well-known lack of predictive power.
The ratio of institutional h over In, Q = h/In, may be used as a measure of citation impact adjusting for the effective networking size.
On the one hand, journals' scientific influence or prestige as computed by the SJR indicator tended to be concentrated in fewer journals than the quantity of citation measured by JIF 3y).
In the leading newspaper, The Globe and Mail (Toronto, March 27 , 2012 Page B7 et seq)., Professor Srivastava was listed in the second place among Canada's top researchers in the discipline of Mathematics and Statistics in terms of productivity and impact based upon a measure of citations of their published works.
We hypothesised that journals which are of high quality are likely to have few articles that are never cited and measures of non-citation in individual journals may therefore provide an alternative and perhaps more appropriate way of comparing journals.
Using field-weighted citation impact (a recognized measure of mean citations per article, normalized for subject field), Wales' citation impact increased from 39% above the world average in 2004 to 68% in 2014.
As such, C ˜ i j ( y ) is a robust measure of cumulative citation impact.
The strength of the h-index is that it provides a single number that describes a researcher's publication performance by combining the number of publications with a measure of their citation frequencies.
The Impact Factor is a measure of the citation frequency of the articles published in a journal and is often used as a proxy to reflect the standing of a journal in its field.
While the impact of a scientific publication is traditionally measured by frequency of citation in subsequent publications, this narrowly defined calculation increasingly fails to capture the true reach of a paper.
