In this study, development of a new index named as Hos index recommended to eliminate h-index's disadvantages, has been aimed. Hos index, considers all publications of scientist. It has been calculated, according to number of citations to publications, by weighting increasingly and removing the effect of publishing start date. In Hos index development, by examining number of citations, number of publications and h-index values, with the help of stratified sampling, a sample selected from 5 counties from 5 continents has been created. Number of citations and effect of publishing start date has been calculated by multiplying and adding number of publications within designated citation intervals with the highest level of percentile value. By dividing this value by the difference between the first and last publication year of scientist, performance value adjusted according to publishing start date (Hos index) has been obtained. In calculation of this index, different weightings are given to researcher's all publications that are cited and uncited.

“…It is this last part that can make interpretation so difficult since a 452 well over-cited core can lead to very large increases in subsequent values of H j . While the rational h-index gives a fractional value to those citations necessary to reach 461 the next value of h, the tapered h-index (Anderson et al 2008) is designed to give every citation 462 for every publication some fractional value. The best way to understand this index is to first 463 consider the contribution of every citation to the h-index.…”

6Personal impact factors (e.g., the h-index) are becoming more and more important in evaluations 7 of faculty with respect to job hiring, promotion, and tenure, but they are largely poorly 8 understood by the community at large. The purpose of this study is to educate biologist and other 9 scientists about some of the wide literature about impact factors, including highlighting their 10 strengths and weaknesses. This includes a thorough exploration of dozens of such indices by 11 comparing how they perform through repeated calculation of data representing 15 years of 12 scientific output of a single individual from beginning through mid-career. Indices are examined 13 with respect to factors such as interpretability, consistency, and stability. 14 15 16PeerJ PrePrints | http://dx.doi.org/10.7287/peerj.preprints.477v1 | CC-BY 4.0 Open Access |

“…The use of this type of diagram in the field of bibliometrics was introduced for the first time by Anderson et al (2008), to generalize the h-index. Considering the PY distribution, each row of the diagram represents a partition of the publications amongst years (see the example in Fig.…”

“…In this sense, this tool complements the information of h PY (which is simply referable to H PY ), giving an instant overview of a scientist's publication output over time. Another indicator to summarize the contents of a Ferrers diagram is given by the tapered h-index, proposed by Anderson et al (2008). A structured comparison between this indicator and the triad indicators is presented in (Franceschini and Maisano 2010b).…”

Evaluating the career of individual scientists according to their scientific output is a common bibliometric problem. Two aspects are classically taken into account: overall productivity and overall diffusion/impact, which can be measured by a plethora of indicators that consider publications and/or citations separately or synthesise these two quantities into a single number (e.g. h-index). A secondary aspect, which is sometimes mentioned in the rules of competitive examinations for research position/promotion, is time regularity of one researcher's scientific output. Despite the fact that it is sometimes invoked, a clear definition of regularity is still lacking. We define it as the ability of generating an active and stable research output over time, in terms of both publications/ quantity and citations/diffusion. The goal of this paper is introducing three analysis tools to perform qualitative/quantitative evaluations on the regularity of one scientist's output in a simple and organic way. These tools are respectively (1) the PY/CY diagram, (2) the publication/citation Ferrers diagram and (3) a simplified procedure for comparing the research output of several scientists according to their publication and citation temporal distributions (Borda's ranking). Description of these tools is supported by several examples.
