Abstract
This study examines the foremost concerns related to most noted research performance index. The most popular and widely acceptable h-index underestimates the highly visible scientist, the middle order group, due to citation distribution issues. The study addresses this issue and uses 'Corrected Quality Ratio' (CQ) to check the implicit underpinnings as evident in h-index. CQ helps to incorporate the aspects of a good research performance indicator. This simple revision performs more intimately and logically to gauge the broader research impact for all groups and highly visible scientists with less statistical error.
Highlights
Metrics/indices play a crucial role for peer-based, metrics-based, or hybrid research evaluation approaches
A whole set of h-type indices are considered for the first case (Table 5); the results indicate that all indices show a high correlation with the traditional metrics, but this relation is stronger with the Observed Impact Indicator (OII)
** Pearson Correlation is significant at the 0.01 level (2-tailed) * Pearson Correlation is significant at the 0.05 level (2-tailed) h-index .591** .888** .802**
Summary
Metrics/indices play a crucial role for peer-based, metrics-based, or hybrid research evaluation approaches. These parameters are measured by Activity Indicator (AI), Observed Impact Indicator (OII), journal related indices, and/or other newly introduced global indices (h and h-type indices) These indicators stand for the quantity, impact, influence, or quality of the scholarly communication. AI measures the quantity of the productivity core (publication) while OII stands for impact of productivity core (citation and its subsequent metrics). The said index aims to measure the impact of scholarly communication in terms of quality (citation) and productivity (publication) in an objective manner. It represents the most productive core of an author’s output in terms of the most cited papers (Burrell, 2007). The publications and citations, which define h-index, are called h-core; whereas publications with citations more/less than h-core are defined as head and core, respectively
