1 Sep 2019 The h-index is a means of measuring scientists' impact on their field, determined from two quantities: the number of publications by a scientist and
The h-index was rapidly taken up as a tool for assessing researchers, perhaps in part due to its simplicity; a scientist has an h-index of n, if she has n papers, with n or more citations. Take for example Dr. Wheatus, Dr. Wheatus has published six papers, with 256, 8, 8, 7, 5, and 2 citations.
For example, if you have published 16 papers, but the first 12 papers have each been cited at least 12 times, and the remaining 4 articles have only been cited 10 times each, then your H-index is 12. 2019-08-04 · An index is a way of compiling one score from a variety of questions or statements that represents a belief, feeling, or attitude. Scales, on the other hand, measure levels of intensity at the variable level, like how much a person agrees or disagrees with a particular statement. The h-index captures research output based on the total number of publications and the total number of citations to those works, providing a focused snapshot of an individual’s research performance. Example: If a researcher has 15 papers, each of which has at least 15 citations, their h-index is 15. Useful For 2010-07-01 · 1.
What is a good h-index? That is a matter of opinion. A colleague and I surveyed typical values for academic physicians in 14 medical specialties (Am J Clin Pathol 2019;151:286-91). The situation is even more complicated due to the fact that h-index represents simultaneously influence of total number of papers, N and rate of citation, R: h = f(N,R). the Glänzel's model * 34,35] is connecting the h-index with those two fundamental scientometric indicators:h=k•N 1/3 •R 2/3(1)On this base E. Csajbok et al. [36] elaborated the master curve ( Fig. 9) for 20 disciplines of Like an index, a scale is also a composite measure.
h index corresponds to a scientist's h of his/her N papers that have been cited at least h times each, while the rest of the N papers have less than h citations each. but The g-index is an index
The hI,annual is meant as an indicator of an individual's average annual research impact, as opposed to the lifetime score that is given by the h-index or hI ,norm. accumulation of layer upon layer of data at various levels, scales and h-index ( see below) of X; publish in journals with an average 'impact factor' (see. 9 Dec 2020 Journal Citation Reports (JCR) · Eigenfactor Web of Science Citation Tools i10-Index = the number of publications with at least 10 citations.

Shannon Index is a commonly used diversity index that takes into account both abundance and evenness of species present in the community. It is explained by the formula: s H = -∑ (P i * ln P i) i=1. where, H = the Shannon diversity index The Hirsch or h-index continues to be one of the most popular author-based metrics, despite some of its flaws and limitations. In some cases, citations to some academics’ work are increasing at a phenomenal pace, and in some exceptional cases such as Highly Cited Researchers (HCRs), whether alive or deceased, citation counts to their work have reached tens or hundreds of thousands, with h In the Theory and practice of the g-index, Leo Egghe (2006) aims to improve on the h-index by giving more weight to highly-cited articles.

The h-index is an author-level metric that measures both the productivity and citation impact of the publications of a scientist or scholar. The h-index correlates with obvious success indicators such as winning the Nobel Prize, being accepted for research fellowships and holding positions at top universities.

Detailed Description. pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
