What's the Matter with Harvard?

When the first global ranking was published by Shanghai Jiao Tong University back in 2003, the top place was taken by Harvard. It was the same for the rankings that followed in 2004, Webometrics and the THES - QS World University Rankings.  Indeed, at that time any international ranking that did not put Harvard at the top would have  been regarded as faulty.

Is Harvard Declining?

But since then Harvard has been dethroned by a few rankings. Now MIT leads in the QS world rankings, while Oxford is first in THE's  and the Chinese Academy of Sciences in Nature Index. Recently Caltech deposed Harvard at the top of the Round University Rankings, now published in Georgia.

It is difficult to get excited about Oxford leading Harvard in the THE rankings. A table that purports to show Macau University of Science and Technology as the world's most international university, Asia University Taiwan as the most innovative, and An Najah National University as the best for research impact, need not be taken too seriously.

Losing out to MIT in the QS world rankings probably does not mean very much either. Harvard is at a serious disadvantage here for international students and international faculty.

Harvard and Leiden Ranking

On the other hand, the performance of Harvard in CWTS Leiden Ranking, which is generally respected in the global research community,  might tell us that something is going on. Take a look at the total number of publications for the period 2017-20 (using the default settings and parameters). There we can see Harvard at the top with 35,050 publications followed by Zhejiang and Shanghai Jiao Tong Universities.

But it is rather different for publications in the broad subject fields. Harvard is still in the lead for Biomedical Sciences and for Social Sciences and Humanities. For Mathematics and Computer Science, however, the top twenty consists entirely of Mainland Chinese universities. The best non - Mainland institution is Nanyang Technological University in Singapore. Harvard is 128th.

You could argue whether this is just a matter of quantity rather than quality. So, let's turn to another Leiden indicator, the percentage of publications in the top 10% of journals for Mathematics and Computer Science. Even here China is in the lead, although somewhat precariously. Changsha University of Science and Technology tops the table and  Harvard is in fifth place.

The pattern for Physical Sciences and Engineering is similar. The top 19 for publications are Chinese with the University of Tokyo in 20th place. However, for those in the top 10% Harvard still leads. It seems then that Harvard is still ahead for upmarket publications in physics and engineering but a growing and substantial amount of  research is done by China, a few other parts of Asia, and perhaps some American outposts of scientific excellence such as MIT and Caltech.

The Rise of China

The trend seems clear. China is heading towards industrial and scientific hegemony and eventually Peking, Tsinghua, Fudan and Zhejiang and a few others will, if nothing changes, surpass the Ivy league, the Group of Eight, and Oxbridge, although it will take longer for the more expensive and demanding fields of research. Perhaps the opportunity will be lost in the next few years if there is another proletarian cultural revolution in China or if Western universities change course.

What Happened to Harvard's Money?

It is standard to claim that the success or failure of universities is dependent on the amount of money they receive. The latest edition of the annual Nature Index tables was accompanied by headlines proclaiming that that China's recent success in high impact research was the result of a long term investment program. 

Money surely had a lot to do with it but there needs to be a bit of caution here. The higher education establishment has a clear vested interest in getting as much money from the public purse as it can and is inclined to claiming that any decline in the rankings is a result of hostility to higher education..

Tracing the causes of Harvard's decline, we should consult the latest edition of the Round University Rankings, now based in Georgia,  which provides ranks for 20 indicators. In 2021 Harvard was first but this year it was second, replaced by Caltech. So what happened?  Looking more closely we see that in 2021 Harvard was 2nd for financial sustainability and in 2022 it was 357th, That suggests a catastrophic financial collapse. So maybe there has been a financial disaster over at Harvard and the media simply have not noticed bankrupt professors jumping out of their offices, Nobel laureates hawking their medals, or mendicant students wandering the streets with tin cups. 

Zooming in a bit, it seems that, if the data is accurate, there has been a terrible collapse in Harvard's financial fortunes. For institutional income per academic staff Harvard's rank has gone from 21st to 891st.

Exiting sarcasm mode for a moment, it is of course impossible that there has actually been such a catastrophic fall in income. I suspect that what we have here is something similar to what happened  to Trinity College Dublin  a few years ago when someone forgot the last six zeros when filling out the form for the THE world rankings.

So let me borrow a flick knife from my good friend Occam and propose that what happened to Harvard in the Round University Rankings was simply that somebody left off the zeros at the end of the institutional income number when submitting data to Clarivate Analytics, who do the statistics for RUR. I expect next year the error will be corrected, perhaps without anybody admitting that anything was wrong.

So, there was no substantial reason why Harvard lost ground to Caltech in the Round Rankings this year. Still it does say something that such a mistake could occur and that nobody in the administration noticed or had the honesty to say anything. That is perhaps symptomatic of deeper problems within American academia. We can then expect the relative decline of Harvard and the rise of Chinese universities and a few others in Asia to continue.

The Remarkable Revival of Oxford and Cambridge


There is nearly always a theme for the publication of global rankings. Often it is the rise of Asia, or parts of it. For a while it was the malign grasp of Brexit which was crushing the life out of British research or the resilience of American science in the face of the frenzied hostility of the great orange beast. This year it seems that the latest QS world rankings are about the triumph of Oxford and other elite UK institutions and their leapfrogging their US rivals. Around the world, quite a few other places are also showcasing their splendid achievements.

In the recent QS rankings Oxford has moved up from overall fifth to second place and Cambridge from seventh to third while University College London, Imperial College London, and Edinburgh have also advanced. No doubt we will soon hear that this is because of transformative leadership, the strength that diversity brings, working together as a team or a family, although I doubt whether any actual teachers or researchers will get a bonus or a promotion for their contributions to these achievements.

But was it leadership or team spirit that pushed Oxford and Cambridge into the top five? That is very improbable. Whenever there is a big fuss about universities rising or falling significantly in the rankings in a single year it is a safe bet that it is the result of an error, the correction of an error, or a methodological flaw or tweak of some kind.

Anyway, this year's Oxbridge advances had as much to do with leadership,  internationalization, or reputation as goodness had with Mae West's diamonds. It was entirely due to a remarkable rise for both places in the score for citations per faculty, Oxford from 81.3 to 96, and Cambridge from 69.2 to 92.1. There was no such change for any of the other indicators.

Normally, there are three ways in which a university can rise in QS's citations indicator. One is to increase the number of publications while maintaining the citation rate. Another is to improve the citation rate while keeping output constant. The third is to reduce the number of faculty physically or statistically.

None of these seem to have happened at Oxford and Cambridge. The number of publications and citations has been increasing but not sufficiently to cause such a big jump. Nor does there appear to have been a drastic reduction of faculty in either place.

In any case it seems that Oxbridge is not alone in its remarkable progress this year. For citations, ETH Zurich rose from 96.4 to 99.8, University of Melbourne from 75 to 89.7, National University of Singapore from 72.9 to 90.6, Michigan from 58 to 70.5. It seems that at the top levels of these rankings nearly everybody is rising except for MIT which has the top score of 100 but it is noticeable that as we get near the top the increase gets smaller.

It is theoretically possible that this might be the result of a collapse of the raw scores of citations front runner MIT which would raise everybody else's scores if it still remained at the top but there is no evidence of either a massive collapse in citations or a massive expansion of research and teaching staff.

But then as we go to the other end of the ranking we find universities' citations scores falling, University College Cork from 23.4 to 21.8, Universitas Gadjah Mada from 1.7 to 1.5, UCSI University Malaysia from 4.4 to 3.6, American University  in Cairo from 5.7 to 4.2.

It seems there is a bug in the QS methodology. The indicator scores that are published by QS are not raw data but standardized scores based on standard deviations from the mean The mean score is set at fifty and the top score at one hundred. Over the last few years the number of ranked universities has been increasing and the new ones tend to perform less well than the the established ones, especially for citations. In consequence, the  mean number of citations per faculty has declined and therefore universities scoring above the mean will increase their standardized scores which is derived from the standard deviation from the mean. If this interpretation is incorrect I'm very willing to be corrected.

This has an impact on the relative positions of Oxbridge and leading American universities. Oxford and Cambridge rely on their  scores in the academic and employer survey and international faculty and staff to keep in the top ten. Compared to Harvard, Stanford and MIT they are do not perform well for quantity or quality of research. So the general inflation of citations scores gives them more of a boost than the US leaders and so their total score rises.

It is likely that Oxford and Cambridge's moment of glory will be brief since QS in the next couple of years will have to do some recentering in order to prevent citation indicator scores bunching up in the high nineties. The two universities will fall again although  it that will probably not be attributed to a sudden collapse of leadership or failure to work as a team.

It will be interesting to see if any of this year's rising universities will make an announcement that they don't really deserve any praise for their illusory success in the rankings.

Comparing the THE and QS Reputation Rankings

This year's Times Higher Education (THE) Reputation Rankings were  a bit boring, at least at the top, and that is just what they should be.

The top ten are almost the same as last year. Harvard is still first and MIT is second. Tokyo has dropped out of the top ten to 11th place and has been replaced by Caltech. Stanford is up three places and is now third. Cambridge and Oxford are both down one place. Further down, there is some churning but it is difficult to see any clear and consistent trends, although the media have done their best to find stories, UK universities falling or sliding or slipping, no Indian or Irish or African universities in the top 100.

These rankings may be more interesting for who is not there than for who is. There are some notable absentees from the top 100. Last year Tokyo Metropolitan University was, according to THE and data providers Thomson Reuters (TR), first in the world, along with MIT, for research impact. Yet it fails to appear in the top 100 in a reputation  survey in which research has a two thirds weighting. Rice University, joint first in the world for research impact with Moscow State Engineering Physics Institute  in 2012 is also absent. How is this possible? Am I missing something?

In general, the THE-TR reputation survey, the data collection for which was contracted out  to the pollsters Ipsos Mori CT, appears to be quite rigorous and reliable. Survey forms were sent out to a clearly defined group, researchers with papers in the ISI indexes. THE claim that this means that their respondents must therefore be active producers of academic research. That is stretching it a bit. Getting your name on a article published in a reputable journal might mean a high degree of academic competence or it could  just mean having some sort of influence over the research process. I have heard a report about an Asian university where researchers were urged to put their heads of  department on the list of co-authors. Still, on balance it seems that the respondents to the THE survey are mostly from a stable group, namely those who have usually made some sort of contribution to a research paper of sufficient merit to be included in an academic journal .

TR also appear to have used a systematic approach in sending out the survey forms. When the first survey was being prepared in 2010 they announced that the forms would be emailed according to the number of researchers recorded by UNESCO in 2007. It is not clear if this procedure has been followed strictly over the last four years. Oceania, presumably Australia and New  Zealand, appears to have a very large  number of responses this year, 10%, although TR reported in 2010 that UNESCO found only 2.1 % of the world's researchers in that region.

The number of responses received appears reasonably large although it has declined recently.  In 2013 TR collected 10, 536 responses, considerably less than in 2012 when it was 16,639. Again, it is not clear what happened.

The number of responses from the various subject areas has changed somewhat. Since 2012 the proportion from the social sciences has gone from 19% to 22% as has engineering and technology while life sciences has gone from 16% to 22%.

QS do not publish reputation surveys but it is possible to filter their ranking scores to find out how universities performed on their academic survey.

The QS approach is less systematic. They started out using the subscription lists of World Scientific, a Singapore based academic publishing company with links to Imperial College London. Then they added respondents from  Mardev, a publisher of academic lists, to beef up the number of names in the humanities. Since then the balance has shifted with more names coming from Mardev with some topping up from World Scientific. QS have also added a sign up facility where people are allowed to apply to receive survey forms. That was suspended in April 2013 but has recently been revived. They have also asked universities to submit lists of potential respondents and respondents to suggest further names. The  exact number of responses coming from all these different sources is not known.

Over the last few years QS have made their survey rather more rigorous. First, respondents were not allowed to vote for the universities where they were currently employed. They were restricted to one response per computer and universities were not allowed to solicit votes or instruct staff who to vote for or who not to vote for. Then they were told not to promote any form of participation in the surveys.

In addition to methodological changes, the proportion of responses from different countries has changed significantly since 2007 with a large increase from Latin America, especially Brazil and Mexico, the USA and larger European countries and a fall in those from India, China and the Asia-Pacific region. All of this means that it is very difficult to figure out whether the rise or fall of a university reflects a change in methodology or distribution of responses or a genuine shift in international reputation

Comparing the THE-TR and QS surveys there is some overlap at the top. The top five are the same in both although in a different order: Harvard, MIT, Stanford, Oxford and Cambridge.

After that, we find that the QS academic survey favours universities in Asia-Pacific and  Latin America. Tokyo is seventh according to QS but THE-TR have it in 11th place. Peking is 19th for QS and 41st for THE -TR. Sao Paulo is 51st in the QS indicator but is in the 81-90 band in the THE-TR rankings. The Autonomous National University of Mexico (UNAM) is not even in THE-TR's top 100 but QS put it 48th.

On the other hand Caltech, Moscow State University, Seoul National University and Middle Eastern Technical University do much better with THE-TR than with QS .

I suspect that the QS survey is tapping a younger less experienced pool of respondents from less regarded universities and from countries with high aspirations but so far limited achievements.

Comparing Engineering Rankings

Times Higher Education (THE) have just come out with another subject ranking, this time for Engineering and Technology. Here are the top five.

1.   Stanford
2.   Caltech
3.   MIT
4.   Cambridge
5.   Berkeley

Nanyang Technological University is 20th, Tsinghua University 26th, and Zhejiang University 47th.

These rankings are very different from the US News ranking for Engineering.

There the top five are:

1.   Tsinghua
2.   MIT
3.   Berkeley
4.   Zhejiang
5.   Nanyang Technological University.

Stanford is 8th, Cambridge 35th and Caltech 62nd.

So what could possibly explain such a huge difference?

Basically, the two rankings are measuring rather different things. THE give a third of their weighting to reputation. Supposedly there are two indicators -- postgraduate teaching reputation and research reputation -- but it is likely that they are so closely correlated that they are really measuring the same thing. Another chunk goes to income in three flavors, institutional, research, and industry. Another 30% goes to citations normalised by field and year.

The US News ranking puts more emphasis on measures of quantity rather quality and output rather than input, and ignores teaching reputation, international faculty and  students and faculty student ratio. In these rankings Tsinghua is first for publications and Caltech 165th while Caltech is 46th for normalised citation impact and Tsinghua 186th.

On balance, I suspect that it is more likely that there will be a transition from quantity to quality than the other way round so we can expect Tsinghua and Zhejiang to close the gap in the THE rankings if they continue in their present form.

The View from Leiden

Ranking experts are constantly warning about the grim fate that awaits the universities of the West if they are not provided with all the money that they want and given complete freedom to hire staff and recruit students from anywhere that they want. If this does not happen they will be swamped by those famously international Asian universities dripping with funds from indulgent patrons.

The threat, if we are to believe the prominent rankers of Times Higher Education (THE), QS and Shanghai Ranking Consultancy, is always looming but somehow never quite arrives. The best Asian performer in the THE world rankings  is the National University of Singapore (NUS) in 24th place followed by Peking University in 29th. The QS World University Rankings have NUS 12th, Nanyang Technological University 13th and Tsinghua University 24th.  The Academic Ranking of World Universities published in Shanghai puts the University of Tokyo in 20th place and Peking University in 71st.

These rankings are in one way or another significantly biased towards Western European and North American institutions and against Asia. THE has three separate indicators that measure income, adding up to a combined weighting of 10.75% . Both QS and THE have reputations surveys. ARWU gives a 30 % weighting to Nobel and Fields awards winners, some of them from several decades ago.

Let's take a look at a set of rankings that is technically excellent, namely the Leiden Ranking. The producers do not provide an overall score. Instead it is possible to create a variety of rankings, total publications, publications by subject groups, publications in the top 50%, 10% and 1% of journals. Users can also select fractional or absolute counting and  change the minimum threshold of number of publications.

Here is the top ten, using  the default settings, publications 2012-15, fractional counting, minimum threshold of 100 papers. Publications in 2006-09 are in brackets.

1. Harvard  (1)
2. Toronto  (2)
3. Zhejiang  (14)
4. Michigan (3)
5. Shanghai Jiao Tong (37)
6. Johns Hopkins (5)
7  Sao Paulo (8)
8. Stanford (9)
9  Seoul National University (23)
10.  Tokyo (4).

Tsinghua University is 11th, up from 32nd in 2006-09 and Peking University is 15th, up from 54th. What is interesting about this is not just that East Asian universities are moving into the highest level of research universities but how rapidly they are doing so.

No doubt there are many who will say that this is a matter of quantity and that what really counts is not the number of papers but their reception by other researchers. There is something to this. If we look at publications in the top 1 % of journals (by frequency of citation) the top ten include six US universities headed by Harvard, three British and one Canadian.

Tsinghua is 28th, Zhejiang is 50th, Peking 62nd, Shanghai Jiao Tong 80th, Seoul National University 85th . Right now it looks like publication in the most reputed journals is dominated by English-speaking universities. But in the last few years Chinese and Korean universities have advanced rapidly, Peking 119th to 62nd, Zhejiang 118th to 50th, Shanghai Jiao Tong 112th to 80th, Tsinghua 101st to 28th, Seoul National University 107th to 85th.

It seems that in a few years East Asia will dominate the elite journals and will take the lead for quality as well as quantity.

Moving on to subject group rankings, Tsinghua University is in first place for mathematics and computer sciences. The top ten consists of nine Chinese and one Singaporean university. The best US performer is MIT in 16th place, the best British Imperial College London in 48th.

When we look at the top 1 % of journals, Tsinghua is still on top, although MIT moves up to 4th place and Stanford is 5th. 

The Asian tsunami has already arrived. East Asian, mainly Chinese and Chinese diaspora, universities, are dominant or becoming dominant in the STEM subjects, leaving the humanities and social sciences to the US.

There will of course be debate about what happened. Maybe money had something to do with it. But it also seems that western universities are becoming much less selective about student admissions and faculty appointments. If you admit students who write #BlackLivesMatter 100 times on their application forms or impose ideological tests for faculty appointment and promotion you may have succeed in imposing political uniformity but you will have serious problems trying to compete with the Gaokao hardened students and researchers of Chinese universities.

MIT and TMU are the most influential research universities in the world

I hope to comment extensively on the new Times Higher Education - Thomson Reuters rankings in a while but for the moment here is a comment on the citations indicator.

Last year Times Higher Education and Thomson Reuters solemnly informed the world that the two most influential places for research were Rice University in Texas and the Moscow State Engineering Physics Institute (MEPhI).

Now, the top two for Citations: research influence are MIT, which sounds a bit more sensible than Rice, and Tokyo Metropolitan University. Rice has slipped very slightly and MEPhI has disappeared from the general rankings because it was realised that it is a single-subject institution. I wonder how they worked that out.

That may be a bit unfair. What about that paper on opposition politics in central Russia in the 1920s?

Tokyo Metropolitan University's success at first seems rather odd because it also has a very low score for Research, which probably means that it has a poor reputation for research, does not receive much funding, has few graduate students and/or publishes few papers. So how could its research be so influential?

The answer is that it was one of scores of contributors to a couple of multi-authored publications on particle physics and a handful of widely cited papers in genetics and also produced few papers overall. I will let Thomson Reuters explain how that makes it into a pocket or a mountain of excellence.

The THE Reputation Rankings

Times Higher Education has produced its third reputation ranking based on a survey of researchers published in ISI indexed journals. The top ten are:

1.  Harvard
2.  MIT
3.  Cambridge
4.  Stanford
5.  UC Berkeley
6.  Oxford
7.  Princeton
8.  Tokyo
9.  UCLA
10. Yale

This does not look all that dissimilar to the academic survey indicator in the  2011 QS World University Rankings. The top ten there is as follows:

1.  Harvard
2.  Cambridge
3.  Oxford
4.  UC Berkeley
5.  Stanford
6.  MIT
7.  Tokyo
8.  UCLA
9. Princeton
10. Yale

Once we step outside the top ten there are some differences. The National University of Singapore is 23rd in these rankings but 11th in the QS academic survey, possibly because QS still has respondents on its list from the time when it used World scientific, a Singapore based publishing company.

The Middle East Technical University in Ankara is in the top 100 (In the QS academic survey it is not even in the top 300), sharing the 90-100 band with Ecole Polytechnique, Bristol and Rutgers. At first glance this seems surprising since its research output is exceeded by other universities in the Middle East. But the technical excellence of its University Ranking by Academic Performance suggests that its research might be of a high quality.

QS Engineering Rankings

QS have started to published detailed subject rankings based on citations per paper over five years and their surveys of academics and employers. The first of these is engineering. There are five subfields: Computer Science and Information Systems, Chemical Engineering, Civil and Structural Engineering, Electrical and Electronic Engineering and Mechanical, Aeronautical and Manufacturing.

For Civil and Structural Engineering the weighting is 50% for the academic survey, 30% for the employers' survey and 20 % for citations per paper. For the others it is 40%, 30% and 30%.

MIT, not surprisingly, is top in each of the five engineering fields that are ranked. In general, the upper levels of these rankings seem reasonable. However, a look at the details, especially in the bottom half, 100-200 places, raises some questions.

One basic problem is that as QS make finer distinctions, they have to rely on smaller sets of data. There were 285 respondents to the academic survey for chemical engineering and 394 for civil and structural engineering. For the employer survey there were 836 for computer science. Each respondent to the academic survey was allowed to nominate up to 40 universities but usually the number was much lower than this. Around the 151-200 level the number of responses would surely have been very low. Similarly, the number of papers counted in each field varied considerably from 43,222 in civil and structural engineering to 514,95 in electrical and electronic engineering. We should therefore be rather sceptical about these rankings.

Something that is noticeable is that there is a reasonably high correlation between the scores for the academic survey and the employer survey. For electrical engineering it is .682, chemical engineering .695, civil engineering .695, computer science .722.

But there is no correlation at all between the citations per paper indicator and the surveys. For electrical engineering it is .064 between citations and academic survey and -.004 between citations and the employer survey. It is the same for the other subfields. None of the correlations are statistically significant.

Looking at the top universities for the three indicators, we see the same familiar places in each of the subfields according to the surveys: MIT, Stanford, Cambridge, Berkeley, Oxford, Harvard, Imperial College London, Melbourne, Caltech.

But looking at the top scorers for citations per paper, we find a much more varied and unfamiliar array of institutions: New York University, Wageningen, Dartmouth College, Notre Dame, Aalborg, Athens, Lund, Uppsala, Drexel, Tufts, IIT Roorkee, University of Washington, Rice, University of Massachusetts.

The agreement of employers and academic about the quality of engineering programs, even though they refer to different aspects, research and graduate employability, suggests that the surveys are moderately accurate, at least for the top hundred or so.

However, the lack of any correlation  at all between the citations indicator and the surveys needs to be raised. It could be that citations have identified up and coming superstars. Perhaps  the number of papers is so low in the various subfields that the indicator does not mean very much. Perhaps citations have been so manipulated in recent years -- see the case of Alexandria University -- that they are no longer a robust indicator of quality.

Which universities have the greatest research influence?

Times Higher Education (THE) claims that its Citations:Research Influence indicator, prepared by Thomson Reuters (TR), is the flagship of its World University Rankings, It is strange then that the magazine has never published a research influence ranking although that ought to be just as interesting as its Young Universities Ranking, Reputation Rankings or gender index.

So let's have a look at the top 25  universities in the world this year ranked for research influence,  measured by field- and year- normalised citations, by Thomson Reuters.

Santa Cruz and Tokyo Metropolitan have the same impact as MIT. Federico Santa MariaTechnical University is ahead of Princeton. Florida Institute of Technology beats Harvard. Bogazici University and Scuola Normale Superiore do better than Oxford and Cambridge.

Are they serious?

Apparently. There will be an explanation in the next post. Meanwhile go and check if you don't believe me. And let me know if there's any dancing in the streets of Valparaiso, Pisa, Golden or Istanbul.

MIT is Number One

The new QS Rankings are out.

MIT has replaced Cambridge in first place.

Thursday, March 10, 2011

The THE Reputation Rankings

Times Higher Education have constructed a reputation ranking from the data collected for last year's World University Rankings. There is a weighting of two thirds for research and one third for postgraduate teaching. The top five are:

1.  Harvard
2.  MIT
3.  Cambridge
4.  UC Berkeley
5.  Stanford

Scores are given only for the top fifty universities. Then another fifty are sorted in bands of ten without scores. Evidently, the number of responses favouring universities outside the top 100 was so small that it was not worth listing.

This means that the THE reputational survey reveals significant differences between Harvard and MIT or between Cambridge and Oxford but it would be of no help to those wondering whether to study or work at the University of Cape Town or the University of Kwazulu-Natal or Trinity College Dublin or University College Dublin.

The scores for research reputation (top fifty for total reputation scores only) show a moderate correlation with the THE citations indicator (.422) and, perhaps surprisingly, a higher correlation with the citations per faculty score on the QS World University Rankings of 2010 (.538).

looking at the QS academic survey, which asked only about research, we can see that there was an insignificant correlation of .213 between the QS scores and the score for citations per faculty in the QS rankings (THE reputation ranking top 50 only). However, there was a higher correlation between the QS survey and the THE citations indicator of .422, the same as that between the THE research reputation scores and the the THE citations indicator.

Comparing the two research surveys with a third party, the citations indicator in the Scimago 2010 rankings, the THE research reputation survey did better with a correlation of .438 compared to an insignificant .188 for the QS academic survey.

This seems to suggest that the THE reputational survey does a better job at differentiating between the world's elite universities. But once we leave the top 100 it is perhaps less helpful and there may still be a role for the QS rankings

What was the greatest ranking insight of 2016?

It is now difficult to imagine a world without university rankings. If they did not exist we would have to make judgements and decisions based on the self-serving announcements of bureaucrats and politicians, reputations derived from the achievements of past decades and popular and elite prejudices.

Rankings sometimes tell us things that are worth hearing. The first edition of the Shanghai rankings revealed emphatically that venerable European universities such as Bologna, the Sorbonne and Heidelberg were lagging behind their Anglo-Saxon competitors. More recently, the rise of research based universities in South Korea and Hong Kong and the relative stagnation of Japan has been documented by global rankings. The Shanghai ARWU also show the steady decline in the relative research capacity of a variety of US institutions including Wake Forest University, Dartmouth College, Wayne State University, the University of Oregon and Washington State University .

International university rankings have developed a lot in recent years and, with their large databases and sophisticated methodology, they can now provide us with an expanding wealth of "great insights into the strengths and shifting fortunes" of major universities.

So what was the greatest ranking insight of 2016?  Here are the first three on my shortlist. I hope to add a few more over the next couple of weeks. If anybody has suggestions I would be happy to publish them.

One. Cambridge University isn't even the best research university in Cambridge.
You may have thought that Cambridge University was one of the best research universities in the UK or Europe, perhaps even the best. But when it comes to research impact, as measured by field and year normalised citations with a 50% regional modification it isn't even the best in Cambridge. That honour, according to THE goes to Anglia Ruskin University, a former art school. Even more remarkable is that this achievement was due to the work of a single researcher. I shall keep the name a secret  in case his or her office becomes a stopping point for bus tours.

Two. The University of Buenos Aires and the Pontifical Catholic University of Chile rival the top European, American and Australian universities for graduate employability. 
The top universities for graduate employability according to the Quacquarelli Symonds (QS) employer survey are pretty obvious: Harvard, Oxford, Cambridge, MIT, Stanford. But it seems that there are quite a few Latin American universities in the world top 100 for employability. The University of Buenos Aires is 25th and the Pontifical Catholic University of Chile 28th in last year's QS world rankings employer survey indicator. Melbourne is 23rd, ETH 26th, Princeton 32nd and New York University 36th.

Three. King Abdulaziz University is one of the world's  leading universities for engineering.
The conventional wisdom seems settled, pick three or four from MIT, Harvard, Stanford, Berkeley, perhaps even a  star rising in the East like Tsinghua or the National University of Singapore. But in the Shanghai field rankings for Engineering last year the fifth place went to King Abdulaziz University in Jeddah. For highly cited researchers in engineering it is second in the world surpassed only by Stanford.

QS Subject Rankings for the Social Sciences

QS have released their subject rankings for the social sciences based on data gathered during last year's rankings.

3.  Oxford

Statistics and Operational Research
1.  Stanford
2.  Harvard
3.  UC Berkeley

Politics and International Studies
1.  Harvard
2.  Oxford
3.  Cambridge

Law

2.  MIT
3. Stanford

Accounting and Finance
1.  Harvard
2.  Oxford
3.  MIT

The top three in the citations per paper indicator is, in most cases, rather different. Are these pockets of excellence or something else?

Sociology

Round University Rankings


The latest Round University Rankings have been released by the Russian company, RUR Rankings Agency. These are essentially holistic rankings that attempt to go beyond the measurement of research output and quality. There are twenty indicators, although some of them such as Teaching Reputation, International Teaching Reputation and Research Reputation and International Students and International Bachelors are so similar that the information they provide is limited.

Basically these rankings cover much the same ground as the Times Higher Education (THE) World University Rankings. The income from industry indicator is not included but there are an additional eight indicators. The data is taken from Thomson Reuters' Global Institutional Profiles Project (GIPP) which was used by THE for their rankings from 2010 to 2014.

Unlike THE, which lumps its indicators together into groups,  the scores in the RUR are listed separately in the profiles. In addition, the rankings provide data for seven continuous years from 2010 to 2016. This provides an unusual opportunity to examine in detail the development of universities over a period of seven years, measured by 20 indicators. This is not the case with other rankings which have fewer indicators or which have changed their methodology.

It should be noted that participation in the GIPP is voluntary and therefore the universities in each edition could be different. For example, in 2015 100 universities dropped out of the project and 62 joined.

It is, however,  possible to examine a number of claims that have been made about changes in university quality over the last few years. I will  take a look at these in the next few posts.

For the moment, here are the top five in the overall rankings and the dimension rankings.

Overall
1.   Caltech
2.   Harvard
3.   Stanford
4.   MIT
5.   Chicago


Teaching
1.   Caltech
2.   Harvard
3.   Stanford
4.   MIT
5.   Duke

Research
1.   Caltech
2.   Harvard
3.   Stanford
4.   Northwestern University
5.   Erasmus University Rotterdam

International Diversity
1.   EPF Lausanne
2.   Imperial College London
3.   National University of Singapore
4.   University College London
5.   Oxford

Financial Sustainability
1.   Caltech
2.   Harvard
3.   Scuola Normale Superiore Pisa
4.   Pohang University of Science and Technology
5.   Karolinska Institute

Unfortunately these rankings have received little or no recognition outside Russia. Here are some examples.

The Shanghai Rankings 3

Two of the indicators in the Shanghai rankings measure research achievement at the highest level. The highly cited researchers indicator is based on a list of those scientists who have been cited most frequently by other researchers. Since ARWU counts current but not past affiliations of researchers, it is possible for a university to boost its score by recruiting researchers. This indicator might then  be seen as signalling a willingness to invest in and to retain international talent and hence a sign of future excellence. 

The top five for this indicator are

1,  Harvard
2.  Stanford
3.  UC Berkeley
4.  MIT
5.  Princeton

This indicator shows that there are a lot of US state universities and non-Ivy League schools that are doing well on this indicator. There is the University of Michigan (6th), University of Washington (13th), University of Minnesota (19th), Penn State (23rd), and Rutgers  (42nd).

Before this year, the methodology for this indicator was simple. If a highly cited researcher had two affiliations then there was a straightforward fifty-fifty division. Things were complicated when King Abdulaziz University (KAU) in Jeddah signed up scores of researchers on part time contracts, a story recounted in Science. ARWU has responded deftly by asking researchers to indicate how their time was divided if they had joint affiliations and this seems to have deflated KAU's score considerably but has had no or minimal effect for anyone else.

The top five universities for papers in Nature and Science are:

1.  Harvard
2.  Stanford
3.  MIT
4.  UC Berkeley
5.  Cambridge

High fliers on this indicator include several specialised science and medical institutions such as Imperial College London, Rockefeller University, Karolinka Institutet and the University of Texas Southwestern Medical Center.

The THE Life Sciences Ranking (subscription required)

First is MIT, then Harvard, then Stanford. Nothing to argue about there.

For research impact (i.e. citations) the order is:

1.. MIT
2. University of Barcelona
3. Harvard
4. Princeton
5. Stanford
6. Oxford
7. Dundee
8. Hong Kong
9. Monash
10. Berkeley

In this subject group, the citations indicator gets 37.5%.

The Shanghai Rankings 2

The Shanghai Rankings get more interesting when we look at the individual indicators. Here are the 2012 top five for Almuni who have won Nobel and Fields awards.

1. Harvard
2. Cambridge
3. MIT
4. Berkeley
5. Columbia

In the top fifty for this indicator there are the Ecole Normale Superieure, Moscow State University, the Technical University of Munich, Goettingen, Strasbourg and the City University of New York City College.

Essentially, this indicator allows universities that have seen better decades to gain a few points from an academic excellence that has long been in decline. City College of New York is an especially obvious victim of politics and bureaucracy.

The top five in the Awards indicator, faculty who have won Nobel prizes and Fields medals, are:

1.. Harvard
2.  Cambridge
3.  Princeton
4.  Chicago
5.  MIT

The top fifty includes the Universities of Buenos Aires, Heidelberg, Paris Dauphine, Bonn, Munich and Freiburg. Again, this indicator may be a pale reflection of past glory rather than a sign of future accomplishments.
