The Twitter Rankings

Coldlime, an Internet marketing company has produced rankings of British and American universities according to Twitter activity.

The five most influential universities in the UK are:

1.   Plymouth
2.   Glasgow
3.   Birmingham
4.   East Anglia
5.   Swansea

The top five in the US are:

1.   Texas at Austin
2.   Wisconsin at Madison
3.   Indiana at Bloomington
4.   Harvard
5.   Florida

Update on Alexandria University

I recently wrote that Alexandria University might be making a comeback. There is some more evidence that this might be the case. The Leiden Ranking now includes 750 universities and Alexandria is there. For most subjects and settings it does not do particularly well but there do seem to be some widely cited publications in Earth and Environmental Sciences plus, of course, a high score for citations in Maths, Computer Science and Engineering. There are not enough papers in Cognitive Sciences and Social Sciences to be ranked.

I received a comment on the previous Alexandria post from "Nadia" that appeared to praise Dr El Naschie and also made apparently defamatory remarks about a British judge and at least two Egyptian public figures. Since this blog has a policy of not publishing possibly libellous comments, it was not approved. However, if "Nadia" should wish to send a comment that is comprehensible and does not contain personal attacks, it will be published. It would help if she or he could verify her identity.

Global Elite Threatened by New Rivals?

The Centre for Science and Technology Studies (CWTS) at Leiden University has produced its annual Leiden Ranking. I hope to write something more general in a couple of days but for the moment here is an elaboration on a brilliant headline by Julie Hare in The Australian.

UTS kicks Harvard's butt in ranking

Well, sort of.  CWTS provide data for nine different indicators and seven different subject groups and there are settings for size and fractional counting. In addition you can vary the number of papers required for inclusion. 

Try clicking on Medical Sciences and Impact Indicator PP (proportion of articles in the top 10% of journals), keeping the default settings for size-independence and fractional counting and making sure the threshold stays at 100 papers. First is Rockefeller University which had 305 papers in Medical Sciences over a four year period, of which a third were in the top 10% of journals. University of Technology Sydney (UTS) had 115 papers and 22 % of those are in the top 10% of journals, that is 6.325 (remember this is fractional counting) papers a year.

Poor Harvard is fifth with 11,958 papers in Medical Sciences of which 2,523.138 are in the top tenth. But that is only 21.1 % .

Change the threshold to 500 papers and UTS disappears. Stop using fractional counting and it goes down to 20th. Uncheck "calculate size-independent indicators" and it sinks to 438th.

There is nothing wrong with presenting data in this much detail: in fact it can be very valuable. There are very probably a few very able researchers at UTS and it is helpful that they have been uncovered. But it would not be a good idea if research grants were to flow to UTS or students to apply there because of a handful of excellent papers a year in one subject.

So, if you manipulate the settings and parameters, there is a good chance that all sorts of institutions will display a pocket of excellence or two. For citations in Cognitive Sciences the University of Puerto Rico (102 papers) is ahead of University College London. For citations in Earth and Environmental Sciences Universiti Sains Malaysia is ahead of Rice. For high quality papers in Maths, Computer Science and Engineering Universiti Malaya beats Yale and for citations Universiti Kebangsaan Malaysia is fourth in the world, although it disappears if the threshold is moved to 500 papers.

Again, this could be useful information but it would be dangerous to assume that these universities now present a major threat to Oxbridge and the Ivy League.

And yes, Alexandria University is there in 211th place for citations (check for size-independent calculations, check for fractional counting, set the threshold at 100 papers) for Maths, Computer Science and Engineering.

Under-50 Universities: Comparing THE and QS

Times Higher Education has just released its list of new universities, those that are less than 50 years old.
The top ten are:
1.   Pohang University of Science and Technology (Postech)
2.   EPF Lausanne
3.   Korea Advanced Institute of Science and Technology (KAIST)
4.   Hong Kong University of Science and Technology
5.   Nanyang Technological University, Singapore
6.   Maastricht University
7.   University of California Irvine
8.   Universite Paris-Sud 11
9.   Universite Marie et Pierre Curie
10. Lancaster University

And here are the top ten from QS's top new universities:

1.   Hong Kong University of Science and Technology
2.   Nanyang Technological University
3.   KAIST
4.   City University of Hong Kong
5.   Pohang University of Science and Technology
6.   Maastricht
7.   University of California Irvine
8.   Hong Kong Polytechnic University
9.   Autonomous University of Barcelona
10. Antwerp University

In some respects the two lists are quite similar. KAIST is in 3rd place, Maastrict in 6th and Irvine in 7th in both lists.Both have two Korean institutions in the top five.

However, there are some noticeable differences, showing the effect of methodology and weighting. There are three Hong Kong universities in QS's top ten but only one in THE's, probably reflecting the greater weight given to internationalisation and reputation in the former. City University of Hong Kong is 4th in the QS rankings and 17th in THE's. Hong Kong Polytechnic University gets 8th and 30th place.

Meanwhile the two French universities in the THE top ten, helped by very substantial scores for citations, are not ranked at all by QS although they had more than enough points in the world rankings. This could be because there are different interpretations about when full university status was achieved.

Will Alexandria University Make a Comeback?

In 2010 the first edition of the new model Times Higher Education  World University Rankings -- powered by Thomson Reuters -- caused amusement and consternation by placing Alexandria University in fourth place for research impact and in the world's top 200 overall.

This extraordinary achievement was entirely the result of the writings of one man, Dr Mohamed El Naschie "of" several universities, one of which was Alexandria University. By citing himself and being cited by others for papers published in a field in which there normally few citations, especially in the first two years after publication, El Naschie pushed the university into a huge score for citation impact.

Anyone interested in the El Naschie story can consult the blog El Naschie Watch. An appraisal of his work's scientific merit can be found in the legal  judgement in 2012 of Mrs Justice Sharp.

In 2011 TR tweaked the citations indicator a bit and managed to get Alexandria's citations score down to 61.4, which was still massively disproportionate to its score for research and its overall score. Then in 2012 it disappeared from the top 400 altogether.

Still the university did not give in. Like an ageing boxer trying for ever more obscure titles, Alexandria showed up in 93rd place in the 2013 THE BRICS and Emerging Economies rankings with a still creditable 31.5 for citations. That score of course represented citations of El Naschie's papers in the years up to 2009 after which he stopped publishing in Web of Science journals. One would expect the score to dwindle further as the number of his countable papers diminished year by year.

It seemed that Alexandria was destined to fade away into the legions of the unranked universities of the world. After his month of wonders in September 2009 when he published eight papers in a single issue of Chaos, Solitons and Fractals, El Naschie published nothing in indexed journals in 2010, 2011 or 2012.

But in July 2013 El Naschie had a paper in the Russian journal Gravitation and Cosmology. Eleven out of 31 cited references were to his own works. That could be a useful boost for Alexandria. However, the paper so far remains uncited.

El Naschie gave Alexandria University as his affiliation and reprint address although the email address appears to be a relic of his days as editor of Chaos Solitons and Fractals.

Will there be more indexed papers from El Naschie? Will Alexandria return to the world rankings?

The Continued Oppression of Women at Oxford

As the advance of women through academia continues there are a few stubborn pockets of non-compliance. It appears that one is Oxford, where in some schools men are more likely to get first class degrees than women. This has excited much comment among educational experts who are generally unconcerned about the poor or declining performance of men in most subjects in most British universities.

Back in 1993 a study by McNabb, Pal and Sloane in Economica found that men were more likely than women to get first class degrees at English and Welsh universities. They were also more likely to get third class, pass or "other" degrees and less likely to get upper seconds but that did not seem to cause much concern.

A recent report by the Higher Education Funding Council for England has discovered that women have caught up with men as far as firsts are concerned while men are still behind with regard to upper seconds and continue to get more third class and other poor degrees.

But there is still work to do. There remain some subjects in some places that have defied global and national trends.

One of these is Oxford where a third of male students got firsts last year compared with a quarter of women. Men were ahead in 26 out of 38 subjects (and presumably behind or equal in 12 although nobody seems very bothered about that). The gap was particularly large in Chemistry, English  and History.

What is the reason for the relatively poor performance of Oxford women in English, Chemistry and History (the relatively poor performance of men in other fields obviously requires no explanation)? A female English student  says it has something to do with the confidence engendered by  "a certain type of all-male public [i.e. private] school". That assumes that it is students from all-male public schools and not state school nerds who are getting all those firsts.

Deborah Cameron, Professor of Language and Communication at Oxford University whose career has obviously failed to reach its full potential because of male bias, claims that it is because borderline first/upper second men are pushed by their tutors in a way that women are not. Is there any real evidence for this?

None of this is new. There was a similar report in 2013. Men were ahead in Politics, Philosophy and Economics, incubator of future politicians, and Modern Languages but behind in Jurisprudence and Classics.

There will no doubt be soul searching, reports, workshops and committees and in the end the imbalance will be rectified, probably by supplementing written exams with coursework and assignments and shifting the borders between first and upper seconds a bit.

I suspect though that it would be more helpful to read Julian Tan in the Huffington Post who writes that he got a first at Oxford by not travelling during spring breaks, saying no to nights out, revising instead of going to the college ball, not sleeping much, not spending much and worrying and complaining too much.

Tan notes that he was in the top four per cent for his subject (he said fourth percentile but that wouldn't get him a first anywhere) so he could probably have had a few trips or nights out before slipping into 2(i) territory. I suspect though that he may located the secret of the surviving pockets of male supremacy, which is the bizarre medical condition that causes some, mainly male, students or employees to find writing code, sitting in archives, reading about how to put out fires or fiddling around with SPSS files more interesting than social relationships, sharing interactive moments or exploring one's emotions.

Should New Zealand Worry about the Rankings?

The Ministry of Education in New Zealand has just published a report by Warren Smart on the performance of the country's universities in the three best known international rankings. The report, which is unusually detailed and insightful, suggests that the eight universities -- Auckland, Otago, Canterbury, Victoria University of Wellington, Massey, Waikato, Auckland University of Technology and Lincoln  --  have a mixed record with regard to the Shanghai rankings and the Times Higher Education (THE) -- Thomson Reuters World University Rankings. Some are falling, some are stable and some are rising.

But things are a bit different when it comes to the QS World University Rankings. There the report finds a steady and general decline both overall and on nearly all of the component indicators. According to the New Zealand Herald this means that New Zealand is losing the race against Asia.

However, looking at the indicators one by one it is difficult to see any consistent and pervasive decline, whether absolute or relative.

Academic Survey

It is true that scores for the academic survey fell between 2007 and 2013 but one reason for this could be that the percentage of responses from New Zealand fell dramatically from 4.1% in 2007 to 1.2% in 2013 (see University Ranking Watch 20th February). This probably reflects the shift from a survey based on the subscription lists of World Scientific, a Singapore- based academic publishing company, to one with several sources, including a sign up facility.

Employer survey

In 2011 QS reported that there had been an enthusiastic response to the employer opinion survey from Latin America and it was found necessary to cap the scores of several universities where there had been a disproportionate response. One consequence of this was that the overall mean for this indicator rose dramatically so that universities received much lower scores in that year for the same number of responses. QS seems to have rectified the situation so that scores for New Zealand universities -- and many others -- recovered to some extent  in 2012 and 2013.

Citations per faculty and faculty student ratio

From 2007 to 2010 or 2011 scores fell for the citations per faculty indicator but have risen since then. The report notes that "the recent improvement in the citations per faculty score by New Zealand universities had not been matched by an increase in their academic reputations score, despite the academic reputation survey being focused on perceptions of research performance."

This apparent contradiction might be reconciled by the declining number of survey respondents from New Zealand noted above. Also, we should not forget the number on the bottom. A fall in the recorded number of faculty could have the same result as an increase in citations. It is interesting that  while the score for faculty student ratio for five  universities -- Auckland , Canterbury, Otago, Victoria University of Wellington and Waikato -- went down from 2010 to 2012, the score for citations per faculty went up. Both changes could result from an a decline in the number of faculty submitted by universities or recorded by QS. In only one case, Massey, did both scores rise. There was insufficient data for the other two universities.

International Faculty and International Students

The scores for international faculty have always been high and are likely to remain so. The scores for international students have been slipping but this indicator counts for only 5% of the total weighting.

New Zealand universities might benefit from looking at the process of submission of data to QS. Have they submitted lists of potential survey respondents? Are they aware of the definitions of faculty, students, international and so on? That might be more productive than worrying about a deep malaise in the tertiary sector.

And perhaps New Zealand salt producers could send out free packets every time the media have anxiety attacks about the rankings.

The Scimago Ibero-America Ranking

In February the SCImago Research Group published its annual Ibero-American Institutions Ranking. This is not a league table but a research tool. The default order is according to the number of publications in the Scopus database over the period 2008-2012. The top five are:

1.  Universidade de Sao Paulo

2.  Universidade de Lisboa

3.  Universidad Nacional Autonoma de Mexico

4.  Universidade Estadual Paulista Julio de Mesquita Filho

5.  Universitat de Barcelona

Why are Britain's Universities Still Failing Male Students?

I doubt that you will see a headline like that in the mainstream media.

A report from the Higher Education Funding Council for England (Hefce) has shown that students who classify themselves as White do better than Black or Asian students who get the same grades at A levels. Mixed-race students are in between. The difference persists even when universities and subjects are analysed separately. 

Aaron Kiely in the Guardian says that this "suggests that higher education institutions are somehow failing black students, which should be a national embarrassment."

He then goes on to recount a study by the National Union of Students (NUS) that indicated that Black students suffered institutional barriers that eroded their self-esteem and confidence and that seven per cent said that the university environment was racist. 

A similar conclusion was drawn by Richard Adams also in the Guardian. He quoted Rachel Wenstone of the NUS as saying that it was "a national shame that black students and students from low participation backgrounds are appearing to do worse in degree outcomes than other students even when they get the same grades at A level."

It is interesting that the Hefce report also found that female students were more likely to get a 2 (i) than male students with the same grades, although there was no difference with regard to first class degrees. Men were also more likely to fail to complete their studies.

So is anyone worrying about why men are doing less well at university?

The Parochial World of Global Thinkers

The magazine Prospect has just published its list of fifty candidates for the title of global thinker. It is rather different from last year. Number one in 2013, Richard Dawkins, biologist and atheist spokesman, is out. Jonathon Derbyshire, Managing Editor of Prospect, in an interview with the Digital Editor of Prospect says that is because Dawkins  has been saying the same thing for several years. Presumably Prospect only noticed this year.

The list is top heavy with philosophers and economists and Americans and Europeans. There is one candidate from China, one from Africa, one from Brazil and none from Russia. There is one husband and wife. A large number are graduates of Harvard or have taught there and quite a few are from Yale, MIT, Berkeley, Cambridge and Oxford. One wonders if the selectors made some of their choices by going through the contents pages of New Left Review. So far I have counted six contributors.

There are also no Muslims. Was Prospect worried about a repetition of that unfortunate affair in 2008?

All in all, apart from Pope Francis, this does not look like a global list. Unless, that is, thinking has largely retreated to the humanities and social science faculties of California, New England and Oxbridge.

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.

The Nature Publication Index

Nature has long been regarded as the best or one of the two best scientific journals in the world. Papers published there and in Science  account for 20 % of the weighting for Shanghai Jiao Tong University's Academic Ranking of World Universities, the same as Nobel and Fields awards or publications in the whole of the Science Citation and Social Science Citation Indexes.

Sceptics may wonder whether Nature has seen better years and is perhaps sliding away from the pinnacle of scientific publishing. It has had some embarrassing moments in recent decades including the publication of a 1978 paper that gave credence to the alleged abilities of the psychic Uri Geller, the report of a study by Jacques Beneviste and others that purported to show that water has a memory. the questionable "hockey stick" article on global warming in 1998 and seven retracted papers on superconductivity by Jan Hendrik Schon.

But it still seems that Nature is highly regarded by the global scientific community and that the recent publication of the Nature Publication Index is a reasonable guide to current trends in scientific research. This counts the number of publications in Nature in 2013.

The USA remains on top with Harvard first, MIT second and Stanford third although China continues to make rapid progress. For many parts of the world, Latin America, Southern Europe, Africa, scientific achievement is extremely limited. Looking at the Asia-Pacific rankings  much of the region including Indonesia, Bangladesh and the Philippines is almost a scientific desert.

The QS Subject Rankings: Reposting

QS have come out with their 2014 University Rankings by Subject, three months earlier than last year. Maybe this is to get ahead of Times Higher whose latest Reputation Rankings will be published next week.

The methodology of these rankings has not changed since last year so I am just reposting my article which was first published in the Philippine Daily Inquirer on 27th May and then reposted here on the 29th May 2013.



The QS University Rankings by Subject: Warning 

It is time for the Philippines to think about constructing its own objective and transparent ranking or rating systems for its colleges and universities that would learn from the mistakes of the international rankers.

The ranking of universities is getting to be big business these days. There are quite a few rankings appearing from Scimago, Webometrics, University Ranking of Academic Performance (from Turkey), the Taiwan Rankings, plus many national rankings.

No doubt there will be more to come.

In addition, the big three of the ranking world—Quacquarelli Symonds (QS), Times Higher Education and Shanghai Jiao Tong University’s Academic Ranking of World Universities—are now producing a whole range of supplementary products, regional rankings, new university rankings, reputation rankings and subject rankings.

There is nothing wrong, in principle, with ranking universities. Indeed, it might be in some ways a necessity. The problem is that there are very serious problems with the rankings produced by QS, even though they seem to be better known in Southeast Asia than any of the others.
This is especially true of the subject rankings.

No new data

The QS subject rankings, which have just been released, do not contain new data. They are mostly based on data collected for last year’s World University Rankings—in some cases extracted from the rankings and, in others, recombined or recalculated.

There are four indicators used in these rankings. They are weighted differently for the different subjects and, in two subjects, only two of the indicators are used.

The four indicators are:
A survey of academics or people who claim to be academics or used to be academics, taken from a variety of sources. This is the same indicator used in the world rankings. Respondents were asked to name the best universities for research.
A survey of employers, which seem to comprise anyone who chooses to describe himself or herself as an employer or a recruiter.
The number of citations per paper. This is a change from the world rankings when the calculation was citations per faculty.
H-index. This is something that is easier to give examples for than to define. If a university publishes one paper and the paper is cited once, then it gets an index of one. If it publishes two or more papers and two of them are published twice each, then the index is two and so on. This is a way of combining quantity of research with quality as measured by influence on other researchers.

Out of these four indicators, three are about research and one is about the employability of a university’s graduates.

These rankings are not at all suitable for use by students wondering where they should go to study, whether at undergraduate or graduate level.

The only part that could be of any use is the employer review and that has a weight ranging from 40 percent for accounting and politics to 10 percent for arts and social science subjects, like history and sociology.

But even if the rankings are to be used just to evaluate the quantity or quality of research, they are frankly of little use. They are dominated by the survey of academic opinion, which is not of professional quality.

There are several ways in which people can take part in the survey. They can be nominated by a university, they can sign up themselves, they can be recommended by a previous respondent or they can be asked because they have subscribed to an academic journal or an online database.

Apart from checking that they have a valid academic e-mail address, it is not clear whether QS makes any attempt to check whether the survey respondents are really qualified to make any judgements about research.

Not plausible

The result is that the academic survey and also the employer survey have produced results that do not appear plausible.

In recent years, there have been some odd results from QS surveys. My personal favorite is the New York University Tisch School of the Arts, which set up a branch in Singapore in 2007 and graduated its first batch of students from a three-year Film course in 2010.In the QS Asian University Rankings of that year, the Singapore branch got zero for the other criteria (presumably the school did not submit data) but it was ranked 149th in Asia for academic reputation and 114th for employer reputation.

Not bad for a school that had yet to produce any graduates when the survey was taken early in the year.

In all of the subject rankings this year, the two surveys account for at least half of the total weighting and, in two cases, Languages and English, all of it.

Consequently, while some of the results for some subjects may be quite reasonable for the world top 50 or the top 100, after that they are sometimes downright bizarre.

The problem is that although QS has a lot of respondents worldwide, when it gets down to the subject level there can be very few. In pharmacy, for example, there are only 672 for the academic survey and in materials science 146 for the employer survey. Since the leading global players will get a large share of the responses, this means that universities further down the list will be getting a handful of responses for the survey. The result is that the order of universities in any subject in a single country like the Philippines can be decided by just one or two responses to the surveys.

Another problem is that, after a few obvious choices like Harvard, MIT (Massachusetts Institute of Technology), Tokyo, most respondents probably rely on a university’s general reputation and that can lead to all sorts of distortions.

Many of the subject rankings at the country level are quite strange. Sometimes they even include universities that do not offer courses in that subject. We have already seen that there are universities in the Philippines that are ranked for subjects that they do not teach.

Somebody might say that maybe they are doing research in a subject while teaching in a department with a different name, such as an economic historian teaching in the economics department but publishing in history journals and getting picked up by the academic survey for history.

Maybe, but it would not be a good idea for someone who wants to study history to apply to that particular university.

Another example is from Saudi Arabia, where King Fahd University of Petroleum and Minerals was apparently top for history, even though it does not have a history department or indeed anything where you might expect to find a historian. There are several universities in Saudi Arabia that may not teach history very well but at least they do actually teach it.

These subject rankings may have a modest utility for students who can pick or choose among top global universities and need some idea whether they should study engineering at SUNY (State University of New York) Buffalo (New York) or Leicester (United Kingdom) or linguistics at Birmingham or Michigan.

But they are of very little use for anyone else.

Changing Responses to the QS Academic Survey

QS have published an interactive map showing the percentage distribution of the 62,084 responses to its academic survey in 2013. These are shown in tabular form below. In brackets is the percentage of the 3,069 responses in 2007.  The symbol -- means that the percentage response was below 0.5 in 2007 and not indicated by QS. There is no longer a link to the 2007 data but the numbers were recorded in a  post on this blog  on the 4th of December 2007.

The proportion of respondents from the USA rose substantially between 2007 and 2013. There were also increases for European countries such as the UK, Italy, Germany, France, Spain, Hungary, Russia, Netherlands and Portugal although there were declines for some smaller countries like Belgium, Denmark, Sweden and Switzerland.

The percentage of respondents from Japan and Taiwan rose but there were significant falls for India, China, Malaysia, Hong Kong New Zealand, Australia, Singapore, Indonesia and the Philippines

The most notable change is the growing number of responses from Latin America including Brazil, Mexico, Chile, Argentina and Colombia.

The Triple Package

I have just finished reading The Triple Package by Amy Chua and Jed Rubenfeld, a heavily anecdotal book that tells us, as every reader of the New York Times now knows, what really determines success.

An irritating thing is the presentation of urban legends -- no dogs, no Cubans and so on -- and generalizations to support the authors' thesis.

Here is one example: "men like Alfred Kazin, Norman Mailer, Delmore Schwatz, Saul Bellow, Celement Greenberg, Norman Podhoretz, and so many of the New York intellectuals who grew up excluded from anti-Semitic bastions of education and culture but went on to become famous writers and critics".

Alfred Kazin went to City College of New York when it was a selective institution. Norman Mailer went to Harvard at the age of 16 and, after serving in the army, to the Sorbonne. Delmore Schwartz attended Columbia, the University of Wisconsin and New York University and did postgraduate work at Harvard with Alfred North Whitehead. Saul Bellow was at the University of Chicago and then Northwestern. He was also also a postgraduate student at the University of Wisconsin. Clement Greenberg studied at Syracuse University. Norman Podhoretz was accepted by Harvard and NYU but went to Columbia which offered him a full scholarship. He went to Cambridge on a Fulbright and was offered a fellowship at Harvard which he turned down

Bellow famously endured several anti Semitic slights and sneers and no doubt did the others. But can we really say that were excluded from bastions of education?

The Best Universities for Research

It seems to be the time of year when there a slow trickle of university ranking spin-offs before the big three world rankings starting in August. We have had young university rankings, best student cities, most international universities, BRICS rankings.

Something is missing though, a ranking of top universities for research. So to assuage the pent up demand here are the top 20 universities for research according to six different ranking indicators. There is considerable variation with only two universities, Harvard and Stanford, appearing in every list.

First the top twenty universities for research output according to Scimago. This is measured by publications in the Scopus database over a five year period.

1.   Harvard
2.   Tokyo
3.   Toronto
4.   Tsinghua
5.   Sao Paulo
6.   Michigan Ann Arbor
7.   Johns Hopkins
8.   UCLA
9.   Zhejiang
10. University of Washington
11. Stanford
12. Graduate University of the Chinese Academy of Sciences
13. Shanghai Jiao Tong University
14. University College London
15. Oxford
16. Universite Pierre et Marie Curie Paris 6
17. University of Pennsylvania
18. Cambridge
19. Kyoto
20. Columbia

Next we have the normalized impact scores from Scimago, which measure citations to research publications taking account of field. This might be considered a measure of the quality of research rather than quantity. Note that a university would not be harmed if it had a large number of non-performing faculty who never wrote papers.

1.   MIT
2.   Harvard
3.   University of California San Francisco
4=  Stanford
4=  Princeton
6.   Duke
7.   Rice
8.   Chicago
9=  Columbia
9=  University of California Berkeley
9=  University of California Santa Cruz
12.  University Of California Santa Barbara
13.  Boston University
14= Johns Hopkins
14= University of Pennsylvania
16.  University of California San Diego
17= UCLA
17= University of Washington
17= Washington University of St Louis
20.  Oxford

The citations per faculty indicator in the QS World University Rankings also uses Scopus. It is not normalized by field so medical schools and technological institutes can do very well.

1.   Weizmann Institute of Technology
2.   Caltech
3.   Rockefeller University
4.   Harvard
5.   Stanford
6.   Gwanju Institute of Science and Technology
7.   UCLA
8.   University of California San Francisco
9.   Karolinska Institute
10. University of California Santa Barbara
11. University of California San Diego
12. London School of Hygiene and Tropical Medicine
13. MIT
14. Georgia Institute of Technology
15. University of Washington
16. Northwestern University
17. Emory
18. Tel Aviv
19. Minnesota Twin Cities
20. Cornell

The Times Higher Education -- Thomson Reuters Research Impact Citations Indicator is normalized by field (250 of them) and by year of publication. In addition, there is a "regional modification" that gives a big boost to universities in countries with generally low impact scores. A good score on this indicator can be obtained by contributing to multi-contributor publications, especially in physics, providing that total publications do not rise too much.

1=  MIT
1=  Tokyo Metropolitan University
3=  University of California Santa Cruz
3=  Rice
5.   Caltech
6.   Princeton
7.   University of California Santa Barbara
8.   University of California Berkeley
9=  Harvard
9=  Stanford
11. Florida Institute of Technology
12. Chicago
13. Royal Holloway,University of London
14.  University of Colorado Boulder
15= Colorado School of Mines
15= Northwestern
17= Duke
17= Universty of California San Diego
19.  Washington University of St Louis
20.  Boston College

The Shanghai Academic Ranking of World Universities Highly Cited indicator counts the number of researchers on the lists compiled by Thomson Reuters. It seems that new lists will now be produced every year so this indicator could become less stable.

1.   Harvard
2.   Stanford
3.   MIT
4.   University of California Berkeley
5.   Princeton
6.   Michigan Ann Arbor
7.   University of California San Diego
8.   Yale
9.   University of Pennsylvania
10.   UCLA
11=  Caltech
11=  Columbia
13.   University of Washington
14.   Cornell
15.   Cambridge.
16.   University of California San Francisco
17.   Chicago
18    University of Wisconsin Madison
19    University of Minnesota Twin Cities
20.   Oxford


Finally, the MNCS indicator from the Leiden Ranking, which is the number of field normalized citations per paper. It is possible for a few widely cited papers in the right discipline to have a disproportionate effect. The high placing for Gottingen results from a single computer science paper the citation of which is required for intellectual property reasons.

1.    MIT
2.    Gottingen
3.    Princeton
4.    Caltech
5.    Stanford
6.    Rice
7.    University of California Santa Barbara
8.    University of California Berkeley
9     Harvard
10   University of California Santa Cruz
11.  EPF Lausanne
12.  Yale
13   University of California San Francisco
14.  Chicago
15.  University of California San Diego
16.  Northwestern
17.  University of  Colorado Boulder
18.  Columbia
19.  University of Texas Austin
20.  UCLA

Will Global Rankings Boost Higher Education in Emerging Countries?

My article in University World News can be accessed here.

India and the World Rankings

There is an excellent article in Asian Scientist by Prof Pushkar of BITS Pilani that questions the developing obsession in India with getting into the top 100 or 200 of the world rankings.

Prof Pushkar observes that Indian universities have never done well in global rankings. He says:

"there is no doubt that Indian universities need to play ‘catch up’ in order to place more higher education institutions in the top 400 or 500 in the world. It is particularly confounding that a nation which has sent a successful mission to Mars does not boast of one single institution in the top 100. “Not even one!” sounds like a real downer. Whether one considers the country a wannabe “major” power or an “emerging” power (or not), it is still surprising that India’s universities do not make the grade." 

and

"It is also rather curious that the “lost decades” of India’s higher education – the 1980s and the 1990s – coincided with a period when the country registered high rates of economic growth. The neglect of higher education finally ended when the National Knowledge Commission drew attention to a “quiet crisis” in its 2006 report."

Even so: 

"(d)espite everything that is wrong with India’s higher education, there is no reason for panic about the absence of its universities in the top 100 or 200. Higher education experts agree that the world rankings of universities are limited in terms of what they measure. Chasing world rankings may do little to improve the overall quality of higher education in the country."

He also refers to the proposal that the Indian Institutes of Technology should combine just for the rankings. Apparently he has been in touch with Phil Baty of THE who is not buying the idea.

I would disagree with Professor Ashok's argument that combining universities would not be a good idea anyway because THE scales some indicators for size. That is true but the reputation survey is not scaled and adding votes in the survey would be beneficial  for a combined institution if one could be created and then accepted by the rankers . Also, you currently need 200 publications a year to be ranked by THE so there would be a case for smaller places around the world --although probably not the IITs -- banding together to get past this threshold.

Recent Research: Rankings Matter

According to an article by Molly Alter and Randall Reback in Education Evaluation and Policy Analysis, universities in the USA get more applications if they receive high quality-of-life ratings and fewer if their peers are highly rated academically.


True for your school: How changing reputations alter demand for selective US colleges

Abstract

There is a comprehensive literature documenting how colleges’ tuition, financial aid packages, and academic reputations influence students’ application and enrollment decisions. Far less is known about how quality-of-life reputations and peer institutions’ reputations affect these decisions. This article investigates these issues using data from two prominent college guidebook series to measure changes in reputations. We use information published annually by the Princeton Review—the best-selling college guidebook that formally categorizes colleges based on both academic and quality-of-life indicators—and the U.S. News and World Report—the most famous rankings of U.S. undergraduate programs. Our findings suggest that changes in academic and quality-of-life reputations affect the number of applications received by a college and the academic competitiveness and geographic diversity of the ensuing incoming freshman class. Colleges receive fewer applications when peer universities earn high academic ratings. However, unfavorable quality-of-life ratings for peers are followed by decreases in the college’s own application pool and the academic competitiveness of its incoming class. This suggests that potential applicants often begin their search process by shopping for groups of colleges where non-pecuniary benefits may be relatively high.
