We provide a comprehensive and critical review of the h-index and its most important modifications proposed in the literature, as well as of other similar indicators measuring research output and impact. Extensions of some of these indices are presented and illustrated.

The aim of this study is to examine the effect of Information and Communication Technology (ICT) development on country’s scientific ranking as measured by H-index. Moreover, this study applies ICT development sub-indices including ICT Use, ICT Access and ICT skill to find the distinct effect...

Nowadays, the world’s scientific community has been publishing an enormous number of papers in different scientific fields. In such environment, it is essential to know which databases are equally efficient and objective for literature searches. It seems that two most extensive databases are...

The capacity of research has increased enormously with number of working and published research papers, research journals, research repositories, indexing and abstracting agencies and research scholars/authors proffering varied knowledge. Every field has its own way of monitoring and evaluation...

Due to the effect of citation impact on The Higher Education (THE) world university ranking system, most of the researchers are looking for some helpful techniques to increase their citation record. This paper by reviewing the relevant articles extracts 33 different ways for increasing the...

h-index retrieved by citation indexes (Scopus, Google scholar, and Web of Science) is used to measure the scientific performance and the research impact studies based on the number of publications and citations of a scientist. It also is easily available and may be used for performance measures...

Citation indexes have attracted the interest of many researchers in the recent years. In this paper we propose a new class of citation indexes which is shown to generalize most of the citation indexes in the existing literature (h-, g-, f-, t-index). The class of indexes is obtained borrowing...

Based on the bibliographical data available with the RePEc (Research Papers in Economics), the Internet Documents in Economics Access Service (IDEAS) publishes every month the up-dated academic rankings of different geographic regions (countries/states in the US). This paper raises the question...

The paper investigates the importance of territorial characteristics/assets (i.e. agglomeration economies, urban infrastructure, factors of labor and cost, development policies, qualitative factors, inter alia) on small- and medium-sized firms’ competitiveness. The analysis uses primary data...
