The full list of journals ranked by H index --- but not the list of highlycited papers :(

Mike Ciavarella's picture

After some conversation with Roozbeh which are "irritatingly useful" :) I found that this site has done already all the calculations we need http://www.scimagojr.com/  except the list of highlycited papers which remains for me the most interesting aspect and which we seem to need to do manually as we did yesterday with IJSS and JMPS at Most cited papers and H-factor of some mechanics journals -- IJSS

Some results are attached as a big PDF file.

First, let start with the general ranking. No surprises in the Top positions, Nature and Science. H=531 and 521, respectively. Very high, very much higher than any engineering / why is it so?  We need to think about this. Then PNAS is fifth at H=339.  Some very good people in mechanics start to publish there, Gao, Freund, to name but a few. That is a good move to get high "H-impact".

Then, a lot of biology immunology and medicine of course, with some physics. We need to go down to rank 227 to find a proper mechanics or materials journal, with Acta Materialia, then 274th,Nature materials with H=235. At 512th, Mat Sci and Eng A.  Later we find all our journals, JMPS and IJSS, but all below H=100!    ;(

Actually you can search from the web site. So Engineering miscellaneous is a much smaller file, also attached.  I think the results are quite different from Impact Factor, so if you want to increase H factor, you should follow this list.  Later I further specify the search for Mech Eng.  JMPS is second with H=62, IJSS 8th with H=52!

Nanotechnology and MEMS are by now much better than plasticity subjects and this is reflected by H.

I am also glad to see WEAR and Tribology in general to be quite high.

Who does the comparisons with impact factors?  Roozbeh instead of replying immediately do please some work for a change!   :)

Finally if we make the TOP H papers for each of our journals, then we can make a book out of them / we can ask Gladwell for example to do it, like he did recently the Eshelby collection. See my comment on this at On Eshelby's two classics

I need however help from Imechanica to complete all this list of DREAM PAPERS.

These lists above are based on SCOPUS.  They also seem to be affected by the same problems we found with our friend Chad yesterday with Google Scholar.

In fact, notice that IJSS is higher than WEAR in the Mech Eng list, but is lower in the Gen Eng list!  How can that be?  It seems when dealing with big lists, these databases start to have problems....  I haven't checked SCOPUS.  I would hope however that the lists are 90% or so reliable.....

I searched (with PoP and GS) using mechanics keyword , and I found quite a few results, what is interesting by removing a few physics papers which are not of interest to us is the following

 1) we find many books, which is nice as normally we rank only papers

 2) we find that books are more cited than papers, and this is informative for students who should always try to read books first

 3) I find my fellow mechanician Ken Johnson extremely good book, extremely high -- and this I like since I have 3 personal copies of that Bible for every office I use!

 4) mechanics as a field seems to be not too bad, with H=300 or so.

 5) I find surprisingly many geomechanics books, not sure why

 6) I find many fracture mechanics textbooks including those from people who are normally not ranked extremely high in papers, but who have a crucial role in our teaching (Broek and Hertzberg for example) since some people prefer to write very few papers, but they should also deserve medals....

 7) the highest papers as usual, Jim Rice --- but this we knew [while we are still waiting for a book from Jim :) sometimes!]

Enjoy the list, if you like it.

I did look for some papers in my bookshelf to provide some better reasons for my claims. You might not see other side of the coin. i have no any reason to opposition to you. i just tried to make the judgements two sided. anyway i try to work on "Methodology based" solutions instead of "Result based" solutions for "Scientific quality improvements".getting feedback from industry may be better solution.

At last some references, although they look all OLD, and BEFORE H-index, in fact these references seem to be on "impact factor", which is the system H-index wants to replace!!!

Of course there is a lot of discussion.  Like in any subject.

These papers look old.

Now UK wants to evaluate everything on citation, because number of "product" was even worse!

There is a lot of discussion in UK about this.  But the truth is that you need to find a BETTER system to replace a system i.e. you need to find a system even LESS questionable.  When you find it, let me know :)

I received these comments from Anne-Wil Harzing, who is an authority in the field, partly in favour of Roozbeh.

 

Mike,

    I know SCIMAGO, but as you indicated their results
are based on Scopus, which has its own limitations, the most notable of
which being that for many journals it only covers the period from 1996
onwards. For those of you interested in citation analysis, you might
want to read up on the work published in information sciences and
library sciences. The most important journals here are Online
Information Review (which has several articles on Google Scholar and
Scopus in comparison with ISI), Scientometrics and JASIST (Journal of
the American Society for Information Science and Technology).

     Of course there is lots of debate about the use of citation analysis,
many more papers similar to those that Roozbeh mentioned are referenced
and discussed in my various papers (white or published) on this topic.
See my research programme Quality and Impact of Academic Research for
more information (http://www.harzing.com/program6.htm). You and Roozbeh
might also be interested in a recent theme issue on "The use and misuse
of bibliometric indices in evaluating scholarly performance" (http://www.int-res.com/abstracts/esep/v8/n1/).

    I thought it was useful to provide some background information.

Best wishes,
Anne-Wil

P.S. You are welcome to publish these comments on your blog and attribute them to me.

Mike,

   I am not sure if this is you or the imechanica page but your text scrolls

way to the right when I view it with FIrefox.  If it is you could you please try and hit the carriage

return a couple more times when you type? It will make reading your informative posts

much easier. Thanks. 

 

@ Peter,

Drupal doesn't insert carriage returns into long html links. Mike's posts had become unreadable because of the long links that he had added.  I've gone and edited the messages and replaced the html with the word "link".  Things should be more readable now.

@ Mike,  

Please try to be considerate to non Microsoft product users and avoid including long html links.  You can go to tinyurl and get smaller urls if the links are long.

It looks fine on my computer, and indeed there were carriage returns. Since you are the first to complain it may be your setup?  Sorry anyway we can ask the imechanica people when they have to check this maybe they can answer you.  Regards, m

Measure for Measure is a play by William Shakespeare,
which deals with the issues of mercy, justice, truth and their relationship
to pride and humility: "Some rise by sin, and some by virtue fall".

Measures for measures is also a Commentary in Nature 444, 1003-1004 (21 December 2006). It proves the following interesting results:

1) impact factor as defined by ISI-Thompson (average number of citations acquired during the past two years for papers published in the same period) is "determined by a small fraction of highly cited papers, so the citation rate for individual papers is largely uncorrelated to the impact factor of the journal in which it was published".

2) The H-index does better than publication frequency, although (as in my comment to Roozbeh) Hirsch choice to define H-index is to equate h=C(h) where C(i) is number of citation of paper i, and so this is a special choice of more general h=A C(h)^K, where A=K=1 decided by Hirsch is not supported by any data and requires further study.

3) the probability for papers with large citations is indeed a power law (at least for the SPIRES database) a/k^gamma, where gamma=2.8 --- therefore, about 50% of all papers have 2 or less citations, top 4.3% of papers produces 50% of all citations

4) "Institutions have a misguided sense of the fairness of decisions reached by algorithm; unable to measure what they want to maximize (quality), they will maximize what they can measure".

5) compared to H-index, mean number of citations per paper is a much better indicator, and simple statistics shows this is especially reliable for large number of papers (like for esthablished researchers).  So we should try that, perhaps on the isihighlycited.com
scientists.

Hence we seem to be able to restart discussion with Roozbeh, Bijwait, Chad and others based on this.  Also, please consider that if we use Google Scholar, we are able to avoid in the long term the ISI-database, which means we will avoid the ISI journals, and hence we can open to open access.  Therefore, there is a huge business and lobby to stop (US$ 9 bn) which presently is not doing its job with accuracy (see the poor representativity of impact factor which has for example Int J Plasticity very high whereas it has very low H index in fact), and which we will change for newer and more scientifically based (non-profit) systems.

I attach below a list of papers which cite the 2006 "Measures for Measures" Nature commentary. 

You will see that the discussion is very active, Hirsch proposed in 2007 to use his index to "predict" the future performances of researchers, some correct for self-citations, some are correlating this with proposal evalutation, some others suggest to use it in peer review.  Some start to judge universities.

So the matter is certainly alive...

I wish to point out that this strong citation influence actually has many negative side effects on scientific research and publication. Main problem is ,Authors who make large part of bibliometrics are not as careful as people who analyze themLaughing. ,Secondly, it has created an extreme situation where many good research papers are congested in the narrow pipelines of a few “top” journals. This congestion may cause delay in publication or, even worse, wasted time as a result of rejection which, as proudly claimed by some “top” journals, happened to over 90% of the submitted manuscripts. Thirdlly, it has helped to form an opinion that articles published in the “top” journals are, without doubt, the most important research and the most significant findings. Therefore, many readers have developed a habit of reading just, if not only, a few “top” journals. Fourthly, it actually encouraged authors to intentionally cite later follow-up articles published in journals with “high” impact factors instead of give due credit to the earlier pioneering works appeared in journals with “low” impact factors. This is because the reference to “top” journals may give a “strong” appearance of the manuscript and, when previous authors favorably cited are actually the board members of the “top” journals (for example NATURE!), the likelihood of acceptance may greatly increased. The drawbacks of citation-driven research may contain many other aspects which I simply have no time and space to write here. But a harsh reality may tell the actual consequence of this practice. Many people actually complain about seeing decrease in the quality of discovery and innovation. Why? I believe part of the reason may be many scientists  are actually chasing for citation and not really looking for best methods.

I remain convinced that we need measurements!

This about measurements in science sounds like the new battle from middle age to renaissance, when there was a tolemaic/aristotelic/catholic system, and we said in science we need a scientific method.

Of course also measurements in science were and are sometimes flawed, however criticisms can be put forward about any theory in economics!

See the Easterlin paradox in economy which suggests since 1974 that economic growth is inversely correlated to country happiness! So we should all look forward to recession... yet this is seen as bad.... We are all unhappy about energy crisis, I am very happy! It will finally increase our conscience about the real needs in society. Of course the energy consumption in US will go down, but the ratio with said, India, will remain the same. Or maybe not? I hope it will go down faster in US because a lot of the US consumption is a waste and not primary need.

Another interesting starting point is that the economic growth by definition is computed as increase of GNP, what is the world total? And how it related to the total of global warming or of total ecological damage on earth? These are parameters to measure. Who said that we need technological progress? Maybe for health, ok. But even there, not to increase huge profits of some companies which then do NOT sell medicines to poor countries.

So we cannot measure anything or we need to start somewhere?

Sumio Iijima
From Wikipedia, the free encyclopedia

Jump to: navigation, search

Sumio Iijima (飯島 澄男 Iijima Sumio, born May 2, 1939) is a Japanese physicist, often cited as the discoverer of carbon nanotubes. Although carbon nanotubes had been observed prior to his "discovery"1,
Iijima's 1991 paper generated unprecedented interest in the carbon
nanostructures and has since fueled intense research in the area of
nanotechnology.

Born in Saitama Prefecture in 1939, Iijima graduated with a Bachelor of Engineering degree in 1963 from the University of Electro-Communications, Tokyo. He received a Master's degree in 1965 and completed his Ph.D. in solid-state physics in 1968, both at Tohoku University in Sendai.

Between 1970 and 1982 he performed research with crystalline materials and high-resolution electron microscopy at Arizona State University. He visited the University of Cambridge during 1979 to perform studies on carbon materials.

He worked for the Research Development Corporation of Japan from 1982 to 1987, studying ultra-fine particles, after which he joined NEC Corporation where he is still employed. He discovered carbon nanotubes in 1991 while working with NEC. He is also a professor at Meijo University since 1999. Furthermore, he is the director of the Research Center for Advanced Carbon Materials, National Institute of Advanced Industrial Science and Technology.

He was awarded the Benjamin Franklin Medal in Physics in 2002,
"for the discovery and elucidation of the atomic structure and helical
character of multi-wall and single-wall carbon nanotubes, which have
had an enormous impact on the rapidly growing condensed matter and
materials science field of nanoscale science and electronics."

He is currently the dean of SKK Advanced Institute of Nanotechnology (SAINT).

Of course here too there is a long history about who has been first:

But I challenges the imechanica people to do better than 11000!  Anyone can compute the H index for this guy?

Mike Ciavarella's picture

and the 2 papers are both from Nature......  does it ring any bell?

Interestingly, the GS H-index for "Sumio Iijima" seems to be 51, which is not extraordinary high, when you consider the huge impact he made, the number of single author Nature papers, and the 3 papers with 1000+ citations.

Certainly this is one of the limitations of H-index --- Hirsch himself said that there is little point in using H-index for, say, Nobel prize winners (they have only an average of 45 in the last 20 years in physics, which means that Iijima could be a winner, with some as low as H=20).

However, maybe interesting to see the full list of the 51 top papers by "Sumio Iijima".

Roozbeh Sanaei's picture

A 2006 editorial written by Marc Monthioux and Vladimir Kuznetsov in the journal Carbon has described the interesting and often misstated origin of the carbon nanotube. A large percentage of academic and popular literature attributes the discovery of hollow, nanometer sized tubes composed of graphitic carbon to Sumio Iijima of NEC in 1991.[1]


In 1952 L. V. Radushkevich and V. M. Lukyanovich published clear images of 50 nanometer diameter tubes made of carbon in the Soviet Journal of Physical Chemistry.
[2] This discovery was largely unnoticed, as the article was published in the Russian language, and Western scientists' access to Soviet press was limited during the Cold War. It is likely that carbon nanotubes were produced before this date, but the invention of the transmission electron microscope allowed the direct visualization of these structures.
Carbon nanotubes have been produced and observed under a variety of conditions prior to 1991. A paper by Oberlin, Endo, and Koyama published in 1976 clearly showed hollow carbon fibres with nanometer-scale diameters using a vapour-growth technique.[3] Additionally, the authors show a TEM image of a nanotube consisting of a single wall of graphene. Later, Endo has referred to this image as a single-walled nanotube.[4]
Furthermore, in 1979, John Abrahamson presented evidence of carbon nanotubes at the 14th Biennial Conference of Carbon at Penn State University. The conference paper described carbon nanotubes as carbon fibers which were produced on carbon anodes during arc discharge. A characterization of these fibres was given as well as hypotheses for their growth in a nitrogen atmosphere at low pressures.[5]
In 1981 a group of Soviet scientists published the results of chemical and structural characterization of carbon nanoparticles produced by a thermocatalytical disproportionation of carbon monoxide. Using TEM images and XRD patterns, the authors suggested that their “carbon multi-layer tubular crystals” were formed by rolling graphene layers into cylinders. Additionally, they speculated that during rolling graphene layers into a cylinder, many different arrangements of graphene hexagonal nets are possible. They suggested two possibilities of such arrangements: circular arrangement (armchair nanotube) and a spiral, helical arrangement (chiral tube).[6]
In 1987, Howard G. Tennent of Hyperion Catalysis was issued a U.S. patent for the production of "cylindrical discrete carbon fibrils" with a "constant diameter between about 3.5 and about 70 nanometers…, length 10² times the diameter, and an outer region of multiple essentially continuous layers of ordered carbon atoms and a distinct inner core…."[7]
Iijima's discovery of carbon nanotubes in the insoluble material of arc-burned graphite rods[8] created the buzz that is now associated with carbon nanotubes. Nanotube research accelerated greatly following the independent discoveries[9][10] by Bethune at IBM[11] and Iijima at NEC of single-walled carbon nanotubes and methods to specifically produce them by adding transition-metal catalysts to the carbon in an arc discharge. The arc discharge technique was well-known to produce the famed Buckminster fullerene on a preparative scale,[12] and these results appeared to extend the run of accidental discoveries relating to fullerenes. The original observation of fullerenes in mass spectrometry was not anticipated,[13] and the first mass-production technique by Krätschmer and Huffman was used for several years before realising that it produced fullerenes.[12]
The discovery of nanotubes remains a contentious issue, especially because several scientists involved in the research could be likely candidates for the Nobel Prize. Many believe that Iijima's report in 1991 is of particular importance because it brought carbon nanotubes into the awareness of the scientific community as a whole. See the reference for a review of the history of the discovery of carbon nanotubes.[1]
In 2000, Professor Tang Zikang and Wang Ning successfully created the smallest stable carbon nanotubes in the world, measuring at just 0.4 nanometres in diameter. [14]

but  Who should be given the credit for the discovery of nanotube?

Henry Small also promoted the idea that citations function as *concept symbols*, essentially a shorthand for an idea expressed by another author.

For instance, if I cite Watson and Crick (Nature, 1953), most scientists will know that I’m referring to the concept of the double-helix of DNA, and I don’t need to go any further to describe the work.

By analyzing the words around a citation, it is possible to create a collective interpretation of what that document stands for. The act of authorship and citation-making can therefore be viewed as a communal dialog.

I must say I disagree with this, at least in my experience, I read a lot more and more broadly because of web, google reader, rss, blogs... but anyway here is this Economist's author opinion.... The expertise for me is narrowing for other reasons.  This, rather, is a good reason for citations to go in crowd like Roozbeh says....  Mike

Great minds think (too much) alike

Jul 17th 2008
From The Economist print edition

Is the web narrowing scientists’ expertise?

Jupiter Images Give me the broader prospective, please

ONLINE databases of scientific journals have made life easier for
scientists as well as publishers. No more ambling down to the library,
searching through the musty stacks and queuing up for the photocopier.
Instead, a few clicks of a mouse can bring forth the desired papers and
maybe others that the reader did not know of—the “long tail” of
information that the web makes available.

Well, that is how it is supposed to work, but does it? James Evans,
a sociologist at the University of Chicago, decided to investigate. His
conclusion, published in this week’s Science, is that the
opposite is happening. He has found that as more journals become
available online, fewer articles are being cited in the reference lists
of the research papers published within them. Moreover, those articles
that do get a mention tend to have been recently published themselves.
Far from growing longer, the long tail is being docked.

Dr Evans based his analysis on data from citation indexes compiled by Thomson Scientific (part of Thomson Reuters).

Mandelbrot, the great genius of fractals (I have my home page with a photo with him, so it is not mistery that I like him being also an "ancien eleve" of Ecole Polytechnique...), has quite a impressive record, he was always anti-conformist and he had hard time to get his first papers in many diverse areas.  It is not entirely true that he is "self-educated" as he seems to suggest, although he had his first job in academia very late, more than 60 years old, still he has an outstanding record for studies in the best schools of the world (Polytechnique, Caltech, Princeton non-linear Institute etc.). 

His most cited "item" is of course the book with a huge 12000 citations.

Then come 2 quite impressive papers at 1000+ citations, both of widespread application: the fractional brownian motion of 1968 with Van Ness, and the application to finance from 1963, a field which lately he has devoted entirely to, with some books.

Then, at about 700 citations, two well known a little divulgative papers, in Science and Nature, respectively.  "How long is the coast of Britain", which is regarded as one of the clear introduction to the concept of fractal in real world geometry.

The other, perhaps one of the immediate interest for imechanica, is the introduction of fractals in fracture [which is why I took the picture with him in Torino few years ago at a special dinner after the ICF conference where he delivered the general lecture on fractals and fracture.]

Last, but not least, comes a very highlycited paper since it is only 2 years old, and already has 5000+ citation.  We should keep an eye on this, although it is in fluids -- intermittent turbulence.  It must be a quite innovative or polemic or breakthrough paper. .  .. . .
