The h-index is an author-level metric that measures both the productivity and citation impact of the publications, initially used for an individual scientist or scholar. The h-index correlates with success indicators such as winning the Nobel Prize, being accepted for research fellowships and holding positions at top universities. [1]
Alternatively, the index can be expressed per 10,000 "points". For example, an index of .25 is the same as 2,500 points. The major benefit of the Herfindahl index in relation to measures such as the concentration ratio is that the HHI gives more weight to larger firms. Other advantages of the HHI include its simple calculation method and the ...
In general, the parameters that are taken into account and eventually determine the new composite-index (c-score) are the following ones: the total number of citations received (NC), the Hirsch index for the citations received (H), the Schreiber co-authorship adjusted Hm index for the citations received (Hm).
The o-index corresponds to the geometric mean of the h-index and the most cited paper of a researcher. [30] RA-index: The RA-index accommodates improving the sensitivity of the h-index on the number of highly cited papers and has many cited paper and uncited paper under the h-core. This improvement can enhance the measurement sensitivity of the ...
A journal's SJR indicator is a numeric value representing the average number of weighted citations received during a selected year per document published in that journal during the previous three years, as indexed by Scopus.
Researchers have used Cohen's h as follows. Describe the differences in proportions using the rule of thumb criteria set out by Cohen. [1] Namely, h = 0.2 is a "small" difference, h = 0.5 is a "medium" difference, and h = 0.8 is a "large" difference. [2] [3] Only discuss differences that have h greater than some threshold value, such as 0.2. [4]
H/h index may refer to: Herfindahl index, a measure of the quantity and competition of firms in an industry; h-index, a measure of scientific research impact
For the nano-scientists that are mentioned on Twitter, their interactions with reporters and non-scientists positively and significantly predicted higher h-index, whereas the non-mentioned group failed. [43] Altmetrics expands the measurement of scholar impact for containing a rapid uptake, a broader range of audiences and diverse research outputs.
