“…The new indicators which emerge from social network considerations may measure different dimensions of the citation networks, or may be highly correlated among themselves 7 . Leydesdorff 7 distinguishes two main dimensions -size and impact -and argues that together they shape a property called 'influence' 13,18 . The dimensions for non-recursive indicators like P, C and i are easily assigned: P has the dimensions of size/quantity and i has the dimensions of impact/quality.…”

The use of conventional journal impact factors (JIFs) for isolated journal ecosystems which belong to what is called science on the periphery has limitations. We propose the power : weakness ratio as an alternative size-independent recursive metric for journal evaluation for such ecosystems. It is based on the idea of recursive citation weighting using graph theoretic tools from social network analysis. The two highly localized ecosystems (i.e. subgraphs isolated from the global graph) chosen are the chemistry journals from India and those from China which are found in the JCR. When the local ecosystems are isolated from the larger global scientific network, the cross-citation behaviour within the local ecosystem reveals different features. This indicator is a more meaningful measure of the standing of each journal in the cross-citation activity within the ecosystem than the well-known JIF which is a global measure.

“…There is a vast body of literature on the JIF (see for example [23][24][25][26][27]). Yang and Zhang proposed a new JIF, calculated with the h-index as one of the variables, as an alternative to the traditional JIF published by ISI-Thomson Reuters [28].…”

Abstract:We used the Journal Impact Factor (JIF) to develop the hjif-index, calculated in a similar way to h-like indices. To this end, we mapped the JIFs of one JCR group to natural numbers, and evaluated the degree of correspondence between the interval from zero to the highest JIF in the group and a set of natural numbers. Next, we plotted the straight line y = x to obtain the group's hjif-index as the JIF corresponding to the journal immediately above the straight line. We call the set of journals above the straight line the hjif-core. We calculated hjif-indices corresponding to the 2-year JIF (hjif2-index) and 5-year JIF (hjif5-index) windows for all 176 JCR groups listed in the 2014 Science edition. We also studied derived indicators such as the distribution of journals in JCR groups according to their hjif-indices, the distribution of journals and JIFs in the hjif-core, and other variables and indicators. We found that the hjif2-and hjif5-index behaved in a similar way, and that in general their distribution showed a peak followed by a relatively long tail. The hjif-index can be used as a tool to rank journals in a manner that better reflects the variable number of journals within a given JCR group and in each group's hjif-core as an alternative to the more arbitrary JCR-based percentile ranking.
