Publication statistics are ubiquitous in the ratings of scientific achievement, with citation counts and paper tallies factoring into an individual's consideration for postdoctoral positions, junior faculty, and tenure. Citation statistics are designed to quantify individual career achievement, both at the level of a single publication, and over an individual's entire career. While some academi...

In this paper,wedefine a First-Citation-Speed-Index (FCSI) for a set of papers, based on their times of publication and of first citation. The index is based on the definition of a h-index for increasing sequences. We show that the index has several good properties in the sense that the shorter the times are between publication and first citation (in a global manner) the higher the FCSI is. We ...

BACKGROUND Due to constantly rising air pollution levels as well as an increasing awareness of the hazardousness of air pollutants, new laws and rules have recently been passed. Although there has been a large amount of research on this topic, bibliometric data is still to be collected. Thus this study provides a scientometric approach to the material published on this subject so far. METHODS...

Research projects can be evaluated through evaluating the research publications produced through those projects. Research publications are evaluation using impact factors and citation indices. There are several citation indices that are proposed and existed to assess the value of a research publication or the research impact of an author or a journal. In this paper, an extensive survey is condu...

BACKGROUND This study was carried out to evaluate activities in different branches of science in Iran compared to other countries over the past 35 years. MATERIALS AND METHODS Essential Science Indicators (ESI) and Web of Science from (Thomson Reuters ISI) and SCImago Journal & Country Rank (SJR) were searched for scientometrics data. ESI indicated place of Iran among other countries in all 2...
