The generalized e-bundle

TL;DR

This paper extends the concept of impact bundles in bibliometrics by introducing a new impact bundle based on the Zhang e-index, and analyzes the conditions under which various definitions form impact bundles.

Contribution

It introduces a new impact bundle based on the Zhang e-index and evaluates the impact of different definitions on forming impact bundles.

Findings

The Zhang e-index can form an impact bundle.

Some plausible definitions do not lead to impact bundles.

Extension of impact bundle concept to new indices.

Abstract

In previous work, we introduced the notion of an impact bundle, showing how e.g., the h-index and the g-index can lead to such a bundle. Here we extend the set of impact bundles by a new impact bundle, based on the Zhang e-index. It is, moreover, shown that some other plausible definitions do not lead to an impact bundle.
