ResearchGate. ResearchGate is a European commercial social networking site for scientists and researchers [2] to share papers, ask and answer questions, and find collaborators. [3] According to a 2014 study by Nature and a 2016 article in Times Higher Education, it is the largest academic social network in terms of active users, [4][5] although ...
RG Score ResearchGate Score or RG Score is an author-level metric introduced by ResearchGate in 2012. [ 13 ] According to ResearchGate's CEO Dr. Ijad Madisch , “[t]he RG Score allows real-time feedback from the people who matter: the scientists themselves.” [ 14 ] RG Score has been reported to be correlated with existing author-level ...
Heckman James J. 2000 RG score 29,77 percentile rank 87,50% Scholes, Myron S. 1997 RG score 17,95percentile rank 65,00% ResearchGate changed their procedures to calculate the RG score, but as of September 1, 2021, Joseph Stiglitz is still listed on ResearchGate with a score of only 8.56 [2] , and ResearchGate remarks as well that
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science. As a journal-level metric, it is frequently used as a proxy for ...
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]
The correlation reflects the noisiness and direction of a linear relationship (top row), but not the slope of that relationship (middle), nor many aspects of nonlinear relationships (bottom). N.B.: the figure in the center has a slope of 0 but in that case, the correlation coefficient is undefined because the variance of Y is zero.
Sensitivity (true positive rate) is the probability of a positive test result, conditioned on the individual truly being positive. Specificity (true negative rate) is the probability of a negative test result, conditioned on the individual truly being negative. If the true status of the condition cannot be known, sensitivity and specificity can ...
Negative consequences of rankings are generally well-documented and relate to the performativity of using journal rankings for performance measurement purposes. [20] [21] Studies of methodological quality and reliability have found that "reliability of published research works in several fields may be decreasing with increasing journal rank", [22] contrary to widespread expectations.
