It is calculated by dividing a scientist's h-index by the number of years that have passed since the first publication, with a score of 1 being very good indeed, 2 being outstanding and 3 truly exceptional. This means that if you have published at least one well-cited document each year since your first publication - a decent textual output by any measure - you are among a successful group of scholars, and if you have published two or three times that number of well-cited. Let's talk numbers: what h-index is good? According to Hirsch, a person with 20 years of research experience with an h-index of 20 is good, 40 is great, and 60 is remarkable. But let's go more into details and have a look what a good h-index means in terms of your field of research and stage of career. What is a good h-index for a Phd student What is considered a good h index? H-index scores between 3 and 5 seem common for new assistant professors, scores between 8 and 12 fairly standard for promotion to the position of tenured associate professor, and scores between 15 and 20 about right for becoming a full professor. What is a good h index for [ What is considered a good h index? Hirsch reckons that after 20 years of research, an h index of 20 is good, 40 is outstanding, and 60 is truly exceptional. The advantage of the h-index is that it combines productivity (i.e., number of papers produced) and impact (number of citations) in a single number. How do you find the H index of a paper What is a Good h-Index? Hirsch reckons that after 20 years of research, an h-index of 20 is good, 40 is outstanding, and 60 is truly exceptional. In his paper, Hirsch shows that successful scientists do, indeed, have high h-indices: 84% of Nobel prize winners in physics, for example, had an h-index of at least 30
The H-index varies among disciplines and depends on the field's citation dynamics. H-index of 40 is considered to be a very good one and H-index of 60 and above is in the level of excellence. I. h index of 40 after 20 years of scientific activity, characterizes outstanding scientists, likely to be found only at the top universities or major research laboratories. h index of 60 after 20 years, or 90 after 30 years, characterizes truly unique individuals. h index of 15-20, fellowship in the National Physical Society Order the publications from highest to lowest number of citations. Then, go down the list until the number of citations for a paper is less than the number of papers you have counted. The h-index is equal to the number of papers (h) that have been cited at least that many times each. 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). We found that, on average. A simple definition of the h-index The h-index was originally defined by J. E. Hirsch in a Proceedings of the National Academy of Sciences article as the number of papers with citation number ≥ h. An h-index of 3 hence means that the author has published at least three articles, of which each has been cited at least three times The h-index is defined as the maximum value of h such that the given author/journal has published at least h papers that have each been cited at least h times. The index is designed to improve upon simpler measures such as the total number of citations or publications. The index works best when comparing scholars working in the same field, since citation conventions differ widely among different fields
Claude Shannon, h-index of 7, commemorised with grafitti. Improving your h-index: black hat techniques. As in every field of human activity, there are some black hat (not accepted or illegal) techniques for academics, which can help you succeed for a short time (i.e, it may increase your h-index, citation score, etc. and help you to gain some academic position or funding), but eventually it. Disciplines differ in their authorship and citation practices, thus discipline-specific h-index norms are desirable. Thus the goal of this study was to examine the relationship between the h-index and academic rank in the field of medical education, and the differences in the h-index between MD's and PhD's in this field. Due to the absence of a formalized registry of medical educators, we. The h-index doesn't take impact factor into account - rather, it is only concerned with the number of citations to your papers. This is a good thing, as we've previously discussed why impact factor is an inadequate measure
Created by Google Scholar and used in Google's My Citations feature. i10-Index = the number of publications with at least 10 citations. This very simple measure is only used by Google Scholar, and is another way to help gauge the productivity of a scholar H-Index = number of papers (h) with a citation number ≥ h. Example: a scientist with an H-Index of 37 has 37 papers cited at least 37 times. Advantages of the H-Index: Allows for direct comparisons within disciplines; Measures quantity and impact by a single value. Disadvantages of the H-Index: Does not give an accurate measure for early-career researchers; Calculated by using only articles.

This translates, collectively, into a dp-index of 1. Values above this are characteristic of leading research departments and this is exactly what is revealed b
Top 5% Authors, h-index, as of March 2021. Explanations; Ranking; More; What this page is about. This page is part of a larger set of rankings for research items, serials, authors and institutions made available on this site. A FAQ is available. Only authors registered with the RePEc Author Service are considered. Only works listed on RePEc and claimed as theirs by registered authors are. h-index is the highest number of papers they have published which have each amassed at least that number of citations: George Whitesides, with an h of 169, has published 169 papers which have each received at least 169 citations, for example
The H-index is an attempt at measuring the productivity and impact of researchers. This is an illustration of the universities' shift from trusting researchers towards micromanagement, efficiency and competition. Charlotte Wien Professor, OPEN Open Patient data Explorative Network, University of Southern denmar A high h-index for somebody who has never been first or corresponding author on any paper is not unusual. Possibly a more realistic example is of a scientist who is very well-known, but whose name I won't mention
Hence an academic with an h-index of 20 has 20 papers with at least 20 citations each. Our ten professors differ substantially in their h-index, with the Pharmacist having an h-index that is more than three times as high as the Cinema Studies academic. On average the professors in the Sciences have a higher h-index (28) than the professors in the Social Sciences and Humanities (21). However, there are individual Social Sciences academics that have h-indices that are equal to or. The h-index of 56 might seem large, but there's been about 70 years of citations (23,000 of them) You raise a good point about citation culture changing, but 10 citations/paper is still quite low in my opinion considering that 50 years of papers were published from 1905-1955, and I'm sure many of them cited relativity, the photo-electric effect, and brownian motion, leaving very little. Background: H-index serves as an alternative to measure academic achievement. Our objective is to study the h-index as a measure of academic attainment in general surgery and surgical specialties. Methods: A database of all surgical programs in the United States was created. Publish or Perish software was used to determine surgeons h-index The h-index is an index that attempts to measure both the productivity and impact of the published work of a scientist or scholar. In Scopus, the h-index is not a static value; it is calculated live on a set of results each time you look it up.The calculation was suggested by Hirsch and it can be summed up as:. A scientist has an index h if h of his/her Np papers has at least h citations each.
We start promoting to full at 1500 citations and h-index of 15 (even for white males). That said, it's a necessary and not a sufficient condition. Yep. 25 in the better UK universities for promoting whyte men to Full. Lower numbers apply to women and PoC. 1 month ago # QUOTE 1 YEA 7 NAY . So that sounds about ballpark. This is strange coming from a Dutch person because there the number of fulls is pretty much fixed. You can't just get promoted. They get tenured as assistant, then if they do well they can hope to make associate (many don't), but very few ever make it to full. It's a weird system and their English. There is no such thing as the precise h-index. The h-index is defined as the largest integer h such that at least h of the author's publications have at least h citations each. But what's a publication? Do first-author publications carry more weight H-index is used to measure a researcher's productivity and the impact of their published documents. H-index. The h-index is an author-level metric that was invented in 2005 by Jorge Eduardo Hirsch, an Argentine-American professor of physics at the University of California, San Diego
The h-index, or Hirsch index, measures the impact of a particular scientist rather than a journal. It is defined as the highest number of publications of a scientist that received h or more citations each while the other publications have not more than h citations each. 1 For example, a scholar with an h-index of 5 had published 5 papers, each of. The h-index is intended to measure simultaneously the quality and sustainability of scientific output, as well as, to some extent, the diversity of scientific research. The h -index is much less affected by methodological papers proposing successful new techniques, methods or approximations, which can be extremely highly cited . He further states that although the H-index is a good measure of scientific ranking, it has some unintended negative consequences: A young researcher may not question the concepts taught by someone with a high H-index, since they assume a high score makes them an expert in their.
That's a very interesting question. The journal impact factor and h index are different in their fundamental design: The former is used to measure journal prestige, while the latter is used to measure researcher impact.Therefore, the two cannot be compared. Let me explain. The journal impact factor measures the average number of citations received by articles published within a journal over. The h-index is a number assigned to individual scholars that measures both their scholarly output and scholarly impact. It is a calculation based on the number of papers a scholar has published, and how often those publications have been cited. The h stands for Dr. Jorge E. Hirsch, a physicist from UCSD, who, in 2005, recommended using this calculation to measure impact. This is the. The h-index threshold for accepting a scientist to be examined is set to 40 provided that most of their publications are in the area of computer science and indexed in DBLP. The threshold was chosen based on the recommendation by J. E. Hirsch, PhD in his An index to quantify an individual's scientific research output paper that an h-index of 40 characterizes outstanding scientists. We. The h-index of a publication is the largest number h such that at least h articles in that publication were cited at least h times each. For example, a publication with five articles cited by, respectively, 17, 9, 6, 3, and 2, has the h-index of 3
The h-index is an index to quantify an individual's scientific research output (J.E. Hirsch) The h-index is an index that attempts to measure both the scientific productivity and the apparent scientific impact of a scientist. The index is based on the set of the researcher's most cited papers and the number of citations that they have received in other people's publications. The h-index also increases according to academic rank (in neurosurgery about five points per rank). 3 In neurosurgery, the persons with the highest h-indices are the Chairs. This may be due to the fact that the h-index is also related to the amount of time spent in a discipline. (The longer the time, the more citations one's papers will get.) H-indices may be obtained by using information.
Science signaling has an h-index of 134.It means 134 articles of this journal have more than 134 number of citations. The h-index is a way of measuring the productivity and citation impact of the publications. The h-index is defined as the maximum value of h such that the given journal/author has published h papers that have each been cited at least h number of times The h-index, developed by UCSD physicist Jorge Hirsch, is one such metric. It ranks the research impact of an author (or group of authors) rather than ranking the impact of their publications. The scale is a sliding ratio of the number of publications that are each cited by more than that same number of other publications. For example, an h-index of 5 would indicate that an author has 5 publications each cited more than 5 times by other publications. This approach pays no regard to. The good qualities of the h-index, compared with IF, are its stability and its balanced combining of quantity and quality, which reduces the over-valuing of journals that publish review articles . Accounts for quantity (number of articles) and quality (defined as number of citations). Journal ranking lists and databases Australian Business Deans Council. Master journal list - registration required to view. Australian Political Science. What is a good h-index when applying for TT positions? I'll be applying for positions in either Psych or Bio and am wondering what I should be aiming for in terms of h-index, which I've heard repeatedly has become the primary metric for evaluating new hires
What is the h Index?<br />Proposed by Hirsch (2005)<br />Quantifies scientific output of a single researcher as a single number:<br />An h index of 40 means that a scientist has published 40 papers that each had at least 40 citations.<br /> original and simple new measure incorporating both quantity and visibility of publications<br /> . First, climbing the h-index ladder is something worth celebrating. If it's worth opening a bottle of champagne or just getting a cafe latte that's up to you, but seriously take your time to celebrate this achievement (there aren't that many in academia). But more importantly, the h-index is one of the measure The h-index measures both productivity and citation impact. To calculate your h-index, list your papers based on the number of their citations, from most to least. The number of citations for each paper must be equal to or greater than its rank in order to be counted. Thus, if your first paper has at least 1 citation, your h index is at least one
The h-index can be calculated by searching for an author's name and creating a citation report in Web of Science. (In the Marked List, you will find the option to Create Citation Report.) Here are a few caveats about use of the h-index: The h-index is intended to be comparable within the same field. For example, it is not accurate to compare the h-index for an author in physics to one in. In most fields of study a JIF of 10 or greater is excellent and in many anything over a JIF of 3 is considered good, but it is essential to remember that JCR impact factors for journals vary markedly across disciplines . My h-index would've been 5 if I were to have 5 numbers bigger than 5, and etc
In this paper, J. E. Hirsch, Dept of Physics, UCSD, proposes the index h, defined as the number of papers with citation number higher or equal to h, as a useful index to characterize the scientific output of a researcher. Here is a partial list of computer science researchers who each has an h index of 40 or higher according to Google Scholar The notion that your h-index matching your age needs to be the new bar is absurd. Good for the author that his does. But dear author, did you have a h-index of 20 when you were 20? Don't generalize your individual experience to all of science • The h-index varies according to the field of study, since the number of scientists working in each discipline (eg, medicine vs physics) is different. • It can never decrease and is therefore not a good measure of recent scientific achievement. h-Index Values by Academic Rank. To put the h-index in context, it is useful to look at typical values for faculty members at North American. The h-index is part of a wider trend in science to rely on metrics - numbers rather than opinions - for assessment. For some, that's like assuming that book sales measure literary merit. It can..
The total sum for the H-index values for top scientists in Canada is 17027 with a mean value for the h-index of 55.28. The total sum for the DBLP publications for leading scientists in Canada is 64485 with a mean value for DBLP publications is 209.37. The highest number of scientists is affiliated with University of Toronto (48 scientists) h-index. Although originally conceived as an author-level metric, the h-index (and some of its numerous variants) have come to be applied to higher-order aggregations of research publications, including journals. A composite of productivity and citation impact, h-index is defined as the greatest number of publications h for which the count of lifetime citations is greater than or equal to h.
The h-index attempts to measure both the productivity and impact of an author.H is the number of articles published by an author which have each been cited at least h times.(E.g., an author published 4 papers that are cited 10, 6 ,5 and 2 times respectively; that author's h-index is 3.) Recently, some databases (e.g. Google Scholar) use an h-index for the journal The H-index, a good indicator of the impact of infectious diseases : The H-index, an indicator commonly used in the world of research, is of relevance in determining the relative impact of infectious diseases. This is the first result obtained by the EU ENHanCe pr..
Having more than one researcher profile is usually a good idea. Why? The reality is that different databases: Use different identification numbers for the same author; Have different publications and different citing articles within them; This creates the opportunity for missed citations! Missed citations can negatively impact the value of your h-index. << Previous: Get Started; Next: Find. How to judge the quality of that research article which was published online after a few months or year. There are few metrics which was taken into consideration for the evaluation of online published articles. Few of them are I10-Index, H-Index & finally Impact Factor of that journal The overall h index of a group will generally be larger than that of each of the members of the group but smaller than the sum of the individual h indices, because some of the papers that contribute to each individual's h will no longer contribute to the group's h. For example, the overall h index of the condensed matter group at the University of California at San Diego physics department is.
Degree, H-index and coreness seem to be independent but are actually interrelated. We construct an operator on a group of reals that returns a node's H-index when acting on its neighbours. Costas and Bordons (2007) mentioned other good properties of the h-index. For example, it is an objective indicator and therefore, it may play an important role when making decisions about promotions, fund allocation and awarding prizes. Moreover, it performs better than other single-number criteria commonly used to evaluate the scienti c output of a researcher (impact factor, total number of. If we calculate a person's true h index (that is, including citations to books and book chapters), 95, 84, and 70 citations (which is quite good), whereas for the other person the corresponding numbers could be 1,650, 1,508, 1,433, 1,226, and 947 (much, much higher). The general point is that h has a property similar to the mode, in that it is not sensitive to extreme values. Yet in. Author-level metrics are citation metrics that measure the bibliometric impact of individual authors. H-index is the best known author-level metric.Since it was proposed by JE Hirsch in 2005 it has gained a lot of popularity amongst researchers while bibliometics scholars proposed a few variants to account for its weaknesses (g-index, m-index are good examples) Her h-index is 25. Is that good? Well, good depends on several variables. First, what is her field of study? What's considered good in Clinical Medicine (84) is different than what is considered good in Mathematics (19). Some fields simply publish and cite more than others. Next, how far along is Anna in her career? Junior researchers have a h-index disadvantage. Their h.
What is a good diversity index? As species richness and evenness increase, so diversity increases. n = the total number of organisms of a particular species. N = the total number of organisms of all species. The value of D ranges between 0 and 1. With this index, 1 represents infinite diversity and 0, no diversity Guides: Metrics and Impact: Journal h-index (Google Scholar, Scopus, Web of Science Jorge Hirsch (2005a, 2005b) recently proposed the h index to quantify the research output of individual scientists. The new index has attracted a lot of attention in the scientific community. The claim that the h index in a single number provides a good representation of the scientific lifetime achievement of a scientist as well as the (supposed) simple calculation of the h index using common. The h-index is skewed by factors other than bias as well. For example, citations of guidelines, reviews, and major clinical studies will be much higher than even important and innovative studies in narrow fields, and middle authors who contributed little to a high-impact publication will none-the-less benefit from its citations. In addition to bias against women's accomplishments, women.
