This article applies an alternative approach to the measurement of scholarly quality, namely the use of TOP-curves, in order to rank journals in the field of environmental and resource economics. This measure summarizes the incidence, intensity, and inequality of these journals' highly cited...

This paper investigates directional returns to scale (RTS) and illustrates this approach by studying biological institutes of the Chinese Academy of Sciences (CAS). Using the following input–output indicators are proposed: senior professional and technical staffs, middle level and junior...

Purpose – The paper aims to propose the use of spline functions for the description and visualization of discrete informetric data. Design/methodology/approach – Interpolating cubic splines: are interpolating functions (they pass through the given data points); are cubic, i.e. are...

We show that usually the influence on the Hirsch index of missing highly cited articles is much smaller than the number of missing articles. This statement is shown by a combinatorial argument. We further show, by using a continuous power law model, that the influence of missing articles is...

Q-measures are network indicators that gauge a node's brokerage role between different groups in the network. Previous studies have focused on their definition for different network types and their practical application. Little attention has, however, been paid to their theoretical and...
