What is an h-index for a scientist?

The h-index is calculated by counting the number of publications for which an author has been cited by other authors at least that same number of times. For instance, an h-index of 17 means that the scientist has published at least 17 papers that have each been cited at least 17 times.

What is a good h-index for a scientist?

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.

Is an h-index of 7 good?

On average and good H-index for a PhD student is between 1 and 5, a postdoc between 2 and 17, an assistant professor between 4 – 35 and a full professor typically about 30+.

What does it mean when a scientist has h-index 3?

The h-index is the largest number h such that h articles have at least h citations each. For example, if an author has five publications, with 9, 7, 6, 2, and 1 citations (ordered from greatest to least), then the author's h-index is 3, because the author has three publications with 3 or more citations.

What is a good h-index by age?

It is simple to calculate. But what should be a good h-index? Hirsch2 was of the opinion that 20 h-index is Good,40 is Outstanding and 60 is Exceptional but after 20 years of research life.

What is an H-index? | How To Research

What is the h-index of 5 after PhD?

An h-index between 1 and 5 might be typical for students nearing the end of their PhD. This means you have 1 to 5 publications that have been cited at least 1 to 5 times, respectively. Your h-index can be calculated using tools like Google Scholar or Web of Science.

What is h-index after Phd?

That said, a good H-index can be considered one that is above the average for their field and discipline. According to a 2019 study of H-indices in the social sciences, the median H-index for PhDs in social sciences is around 8, with a range of 2 to 21 depending on the specific field of study.

Is 3 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.

How good is an h-index of 2?

It's calculated by dividing a scientist's h-index by the number of times that have passed since the first publication, with a score of 1 being veritably good indeed, 2 being outstanding and 3 truly exceptional.

Is 1,000 citations a lot?

Most authors of highly cited papers have fewer than 1000 citations, which is very little in comparison with the highest numbers indicated in the top part of Table S1. Table S1 shows a high degree of rank–rank correlation between the number of citations, h-index, and scientific degree, which are over 0.9 (citations vs.

Who has the highest h-index in the world?

Scientists with High H-Indexes

At the time of writing, the highest score recorded by Google Scholar is 300, by researcher Ronald C Kessler from Harvard University. JoAnn E Manson from Brigham and Women's Hospital takes second place with a score of 294.

What is the average h-index for a full professor?

“A typical h-index for full professors ranges from 12 to 24.” Or, as Hirsch put it: 84 per cent of Nobel prize winners in physics had an h-index of at least 30, which is outstanding (Hirsch, 2005b).

How many citations does Albert Einstein have?

For his 147 articles, Einstein has received 1,564 citations during his lifetime.

What is a good h-index after 20 years?

Per Hirsch: h index of 20 after 20 years of scientific activity, characterizes a successful scientist.

What are the disadvantages of the h-index?

The limitations of the h-index include: 1. It does not take into account the total number of citations. For example, imagine that another scholar also has 15 publications, and also 8 of them have more than 8 citations, but each of the first five were cited more than a thousand times.

What is the h-index of Nobel laureates?

2; the median is at h_m = 35, lower than the mean due to the tail for high h values. It is interesting that Nobel prize winners have substantial h indices (84% had an h of at least 30), indicating that Nobel prizes do not originate in one stroke of luck but in a body of scientific work.

Does h-index really matter?

It can be useful for identifying the centrality of certain researchers as researchers with a higher h-index will, in general, have produced more work that is considered important by their peers.

Is 70 a good h-index?

The statistical variance in the data set was quite large so the averages should be taken with a grain of salt. The same study found that if you are aiming for a Nobel Prize, your h-index needs to be at least 35 and preferably much closer to 70.

Is there a rank higher than PhD?

The higher doctoral degree, D.Sc, is earned 6-8 years after the post Ph. D. The candidates with higher academic titles, professional skills, and innovative research could compete and achieve top-ranked positions worldwide.

What degree is greater than a PhD?

Doctorate degrees are the highest level of education you can achieve in many countries. However, there are some countries that have qualifications considered higher than a PhD such as professional degrees, habilitation degrees, doctor of science and doctor of technology.

Does PhD ranking matter?

When it comes to selecting a PhD program, rankings are only one of many factors to consider when looking at graduate schools. It's important to be realistic and understand that ranking alone should not carry the most weight in your decision-making process when choosing a PhD.

Can you do a PhD with a level 7?

Level 7 (13-180 credits) = Master's Degree, Level 7 Cert/Diploma = Highly Developed Knowledge & Skills. Level 8 (120-540 credits) = Doctorate, DBA, DPhil, PhD, Level 8 Diploma = Research New Knowledge & Skills.

What is the level of a PhD?

Level 8. Level 8 qualifications are: doctorate, for example doctor of philosophy ( PhD or DPhil )

What are the PhD grades?

For most substantial courses students receive one of the following grades: A+, A, A-, B+, B, B-, C+, C, C-, D+, D, or F. The points awarded for each credit of a plus/minus grade are: A+=4.00, A= 4.00, A-=3.84, B+=3.33, B=3.00, B-=2.67, C+=2.33, C=2.00, C-=1.67, D+=1.33, D=1.00, F=0.00.
