THE Under Fire in the Far North and Down Under

Times Higher Education  (THE) has been attacked for the latest spin-off from its world rankings. Alex Usher of Higher Education Strategy Associates has tweeted "your "most international unis" rankings lack even the barest face validity. Galway more intl than Harvard? C'mon"

The higher education editor of the Australian, Julie Hare, reports that Australian observers are surprised that Monash university, reputed tp be the most international Australian university, has been ranked so low and quotes a comment at THE: "What cretin can assert that LSE and Cambridge are less "international" than Brunel and Canterbury?"

I wonder if there will be similar comments on THE's preview, in advance of a summit in Qatar, of its forthcoming MENA rankings. This is the top five of a research impact indicator based on field and year normalised citations. The first place goes to Texas A and M University Qatar. The other four are the Lebanese American University, King Abdulaziz University, Jeddah, Qatar University and the American University of Beirut.

In case you are wondering, Texas A and M Qatar does have someone on  the Large Hadron Collider project.

The Most International Universities

Times Higher Education has released its list of the top 100 most international universities. This is simply the International Outlook indicator extracted from last year's world rankings. It counts the proportion of international staff and faculty and the percentage of papers with  international collaborators.

The top three are in Switzerland. The National University of Singapore is fourth and Ecole Polytechnique in Paris fifth. The Ecole is up from 28th place last year which probably means a "clarification of data" of some sort.

So what makes a university international?

It helps a lot to be located in an English speaking country. The UK, and Australia get high scores.

What is more noticeable is that many  small countries to do well especially if they are located next to a big country with the the same or similar language and culture -- Switzerland, Singapore, Macau, Hong Kong, Austria, Denmark,  Big countries like Mainland China, the USA and India do not.

Perhaps THE (and QS) should think about the implications of its methods. Does it make sense to count as international a student who moves a few miles from Fermanagh to Galway, Bavaria to Austria or Johor to Singapore.?

Perhaps the THE should count the whole of the EU as a single country or give extra points for students and faculty who cross an ocean rather than an increasingly meaningless line on a map. Perhaps also, Macau and Hong Kong should be reunited methodologically with the Mainland. What about counting out of state students at US universities?

More University Mission Creep

Demands on western universities continue to increase and so do calls for more and more indicators in national and global rankings. Universities, it seems, are underemployed if they just provide instruction in academic, professional and technical subjects and promote research and scholarship.

Now they are supposed to support diversity and inclusiveness, build character, grit and resilience, promote anti-racism, combat sexism, homophobia, cisgender normativity and weightism, boycott Israel, reward students for overcoming adversity, engage with communities, combat terrorism, transform lives, provide gender free bathrooms, sponsor near-professional level sports teams, boycott fossil fuels, make everybody safe and comfortable except for those whose privilege needs continued confrontation.

All this is now spilling over into the rankings business. We have already seen Universitas 21, which ranks national university systems, give countries a score for the number of female students and faculty.and there have been repeated proposals  that the US News law school rankings should include faculty  and student diversity among their criteria.

US News has published a diversity index that consists simply of calculating the percentage of minority students. First place goes to Cornell, followed by the University of Hawaii - Manoa, Whitter College, California, the University of the District of Columbia and Nova Southeastern University in Florida. A quick calculation of the correlation between the diversity index and overall scores in the law school rankings shows no significant relationship between diversity so defined and overall quality as measured by the rankings.

To incorporate such an index into the law school rankings would be a pointless exercise.  If Nova Southeastern Unversity Law School, which accepts nearly half of those who apply and a third of whose graduates are not employed nine months after graduation, were to get a high ranking, this would be seriously misleading for everybody.

The US federal government is now proposing to rate colleges according to their admission of low income and first generation students, affordability, and outcomes such as graduation rates, graduate employment and entry into postgraduate programs. The problem here is that in the US and  almost everywhere else these objectives are mutually exclusive. Low income students are, on average, likely to be less academically capable, and that means, if academic standards remain unchanged, that fewer will graduate and fewer will go on to graduate study.

If the ratings plan ever happens the likeliest consequence of the colliding demands is that it will become much easier to get a degree or get into graduate school. There are dozens of ways in which academic standards can be eroded, most of which we have seen already somewhere.

Another kind of creep is the rising chorus that universities should encourage and promote civic engagement, a rather slippery concept that is difficult to describe but covers  a variety of worthy activities reaching beyond the campus such as promoting local economic development, employing women and minority groups, helping poor students succeed, buying local products and encouraging students to be volunteer teachers, . A recent conference in South Africa ended with a call for action that included a proposal that rankings should take account of such activities.

Adam Habib, Vice-Chancellor of the University of the Witwatersrand, even proposed to boycott rankings unless they included civic engagement as an indicator.

"Gather a group of universities and tell the rankings that you'll collectively withdraw if they don't take in civic engagement in the future. I guarantee that every one of them will listen".

But why should universities be required to do what other institutions have failed to do even though they are far better qualified. If entrepreneurs cannot promote economic growth, revolutionary parties cannot achieve social justice, trade unions cannot help the poor then just why should should universities be expected to do so?

Part of the drive for new indicators is probably rooted in the realisation that universities are losing much of their reason for existence. Research is increasingly done by specialised institutes, companies and hospitals, for- profit organisations offer no frills instruction at low prices, online learning is replacing traditional seminars and lectures. Civic engagement looks like the new quality audit, a way of keeping busy those who are reluctant to teach or research.

If all the demands for new indicators are met we will end up with hugely bloated rankings that fail to make any meaningful distinctions.

New Resource from IREG

A new resource for anyone interested in university rankings is available at the International Rankings Experts Group (IREG) site.

The Inventory of National Rankings has been prepared by the Perspektywy Education Foundation, Poland, and provides basic data about a variety of national ranking systems. Two of them have been approved by IREG.

US Federal Ratings Plan: A Few Answers, More Questions

The US Department of Education has just revealed the progress that it has made towards its planned ratings for colleges and universities. There has been over a year of public discussion since the Obama administration announced that it was planning on introducing a new system. Unfortunately, it seems that there is still a long way to go before a final product emerges and the administration’s forecast of a launch in August or September 2015 may be too optimistic.

Since the 1980s, the US News& World Report’s ‘America’s Best Colleges’ has been followed avidly by students and other stakeholders. These rankings have been criticised, sometimes with justification, but they do provide a reasonably accurate guide to some of the things that students, parents, employers and counsellors want to know: how likely a student is to graduate once admitted, the typical academic ability of fellow students, reputation among peers, resources available for teaching.

There is, of course, much that the US News rankings do not tell us. The international rankings produced by Shanghai Jiao Tong University’s Center for World-Class Universities, Quacquarelli Symonds (QS), Times Higher Education and now US News with its Best Global Universities are probably even more limited since they focus largely or entirely on research and postgraduate training. There is also a widespread feeling that existing rankings are unfair to schools that try to educate students from non-traditional backgrounds or underrepresented groups.

The demand for more information and for greater accountability comes when American universities are entering a time of increasing pressure and constraint. Costs are rising inexorably, even though many students are taught not by hugely expansive superstar professors but by poorly paid adjuncts and untrained graduate assistants. Many students graduate late or not at all and incur a large and growing debt burden from which bankruptcy rarely provides an escape. Meanwhile the more reliable global university rankings show American universities steadily losing ground to Asian institutions.

Many colleges and universities are facing a death spiral as stagnant or declining admissions lead to a fall in the number of graduates which in turn erodes reputation and undermines alumni contributions. Underlying everything is the grim reality that the overall quality of graduate of American high schools is apparently insufficient to supply colleges and universities with students capable of completing a degree within a reasonable length of time.
The federal government has become increasingly concerned over these trends and the failure of American higher education to provide a route to secure employment and middle class status. The new plan had its origins in a speech by President Obama at the University at Buffalo: SUNY in August 2013.

A succession of hearings and forums has been held and finally the Department of Education has come out with a draft framework. The department has indicated that it will publish ratings, not rankings, so that colleges and universities will be divided into three categories, high performers, low performers and those in between. Two year institutions such as community colleges and four year colleges and universities will be assessed separately and institutions that teach only postgraduates or do not grant degrees will not be included. The main source of data will be information collected by the federal government.

According to the document, ‘For Public feedback: A College Ratings Framework’, the objectives are to help colleges measure and make progress towards the objectives of access, affordability and outcomes, to provide information for students and families, and to help the government ensure that financial aid is well used.

The department has announced the indicators it is thinking about using. These include enrolment of low income and first generation students, family income levels and the average net price of an institution. Student outcomes could be measured by completion rates, transfer rates and the number of students going on to graduate school. More details can be found in ‘A New System of College Ratings– Invitation to Comment’.

Several questions remain unanswered. A rating consisting of three categories may be too crude. There will almost certainly be a large gap between those at the top of the high performing group and those on the edge of the intermediate category. Membership of the same large group will not help anyone trying to compare two universities. A small change in one or two indicators might push colleges out of the intermediate group into the underperformers where they could suffer financial sanctions.

If the department provides the scores or raw data for each indicator then it would be relatively simple for analysts or journalists to calculate numerical rankings.

The most disquieting thing about this document is that the department seems to have given little thought about how easy it would be to game much of the data. There are, for example, dozens of ways in which colleges and universities could increase the number of students who graduate on time, even if it means undermining the quality of their degrees and their value to potential employers. Rating institutions according to the repayment of student loans might encourage universities to close humanities and social science departments while coaxing students into programs for which they might not be suited.

It is likely that there will be more arguments and discussion before the ratings are launched and it remains to be seen how much credibility they will have when they do appear.

Is Asia really rising?

Over the last few years there has been a lot of talk about the continuing rise of Asian universities. In The Conversation, Gerard Postiglione of the University of Hong Kong has pointed out that Asian universities now take one in eight of the top 200 places in the Times Higher Education World University Rankings and he predicts that by 2040 a quarter of the top universities will be Asian.

It is interesting that he apparently regards the THE rankings as the arbiter of excellence despite an eccentric methodology that, among other oddities, claims that an excellent but small research institute is the best university in Italy and among the best in the world.

Exactly what progress in the THE rankings means is difficult to decide. A rise in the score for the research indicator, for example, could result from an increase in the number of publications, a fall in the number of academic and/or research staff, an increase in research income, an improvement in the research reputation survey or a combination of some or all of these.

Predicting what will happen in the THE rankings has become even more difficult since THE broke up with their data supplier, Thomson Reuters, raising the possibility that there will be another round of methodological changes.

There are some sceptics such as Alex Usher of Higher Education Strategy Associates but in general the rise of Asia and the decline of the US and UK seems to have become part of the accepted wisdom of Western pontificators.

So is Asia rising? And if it is, is it the whole of the continent or just parts of it?

The problem is that the rankings vary in their ability to identify medium term trends. QS and THE give a large weighting to reputation surveys that are inherently volatile,They also use an unstable number of institutions to generate means from which processed scores are calculated and this can led to fluctuations in the final overall scores

The Academic Ranking of World Universities (ARWU) produced by the Shanghai Center for World-Class Universities is probably the most useful for identifying changes over the last decade since there were no significant changes between 2004 (when schools with strengths in the social sciences  were helped by exemption from the Nature and Science indicator) and 2014 (when Thomson Reuters issued a new list of highly cited researchers).

The number of universities in the Shanghai top 500 provides strong evidence that some parts of Asia are making rapid progress. The number of mainland Chinese universities (excluding Hong Kong and Taiwan) has risen from 8 to 33, The number of Korean universities has gone from eight to ten, Taiwanese from three to six, Saudi from zero to four, and Malaysian from zero to two.

But some parts of Asia appear to be stagnant or in relative decline. The number of Japanese universities has fallen from 36 to 19 and Indian from three to one while the number of Hong Kong institutions has remained the same at five.

Looking at the performance of some national flagships in the ARWU publications indicator provides more evidence of an expansion of research in some Asian countries. Compared to Harvard's benchmark score of 100, Peking University has risen from 49.8 in 2004 to 63.6 in 2014. Other Asian universities have also had substantial  growth over the decade. Seoul National University went from 62.6 to 67.8, National Taiwan University from 52.6 to 57.9 and Istanbul University from 30.7 to 34.9.

Note that the raw numbers of publications have been modified by a logarithm so that in 2004 Peking was in fact publishing about a quarter of the number of papers produced by Harvard rather than a half.

On the other hand, Tokyo University, which in 2004 had the second highest publications score in the world, fell from 91.9 to 73 and the University of Hong Kong from 46.4 to 44.

If we look at Shanghai's Productivity per Capita indicator, which measures quality by dividing  five combined indicators by the number of faculty, we find some Asian universities doing well. Peking goes from 5.9 to 16.5, Seoul National University from 19 to 23.4 and National Taiwan University from 17.5 to 19.9. Tokyo, meanwhile, has fallen from 49.8 to 29.2. Hong Kong University, on the other hand,has risen from 13.1 to 22.4.

Confirmation of the trends for research output comes from the Output indicator in the Scimago rankings, which is based on data provided by Scopus. Peking, Seoul National University, National Taiwan University and Universiti Malaya rose between 2009 and 2014. However, the scores for Tokyo and Hong Kong both fell.

On the other hand, the evidence of Scimago' normalised impact indicator, which might measure research quality, shows Peking rising but Seoul National University and Hong Kong falling.

It would seem that China and the overseas Chinese communities and Korea are expanding the quantity of research but progress at higher levels is slower. There are also islands of research productivity in West and Southeast Asia.  In Central Asia, the Indian Subcontinent and Indonesia there is very little significant research activity while Japan is actually declining.

One Way of Rising in the Rankings

One way of rising in the rankings is to amalgamate. Watch out for Paris-Saclay in next year's Shanghai rankings.

From BBC Online News:

"Dominique Vernay, the president of this new university, says that within a decade he wants Paris-Saclay to be among the top ranking world universities.
"My goal is to be a top 10 institution," he says. In Europe, he wants Paris-Saclay to be in the "top two or three".
In university rankings, big is beautiful, and the Paris-Saclay will have 70,000 students and 10,000 researchers. There will be an emphasis on graduate courses and recruiting more international students and staff.
The idea of bringing together individual colleges into a "federal university" has been borrowed from the UK.
"Our model isn't that far from the Oxbridge model," he says.
To put it into scale, Mr Vernay says Paris-Saclay is going to be twice the size of the University of California, Berkeley, one of the flagships of the US university system."

Ranking Status Wars 3

The US News and World Report's Best Global Universities has been admitted to the ranks of the elite rankings. The Hong Kong government has announced a scholarship programme that will pay tuition and bursaries at universities in the top 100 of the QS world rankings, the THE world rankings, the Shanghai rankings and the USNWR global rankings.

More on the Ranking Status Wars

The Economist thinks there are two international university rankings worth talking about. Will the prestigious THE rankings continue to be prestigious now they are no longer powered by Thomson Reuters but have to share their data partner with QS?

"But most universities still have far to go. Only two Chinese institutions number in the top 100 in the Times Higher Education World University Rankings. Shanghai’s Jiao Tong University includes only 32 institutions from mainland China among the world’s 500 best. The government frets about the failure of a Chinese scholar ever to win a Nobel prize in science (although the country has a laureate for literature and an—unwelcome—winner in 2010 of the Nobel peace prize, Liu Xiaobo, an imprisoned dissident)".

The Times [Higher Education rankings] they are a-changing

Maybe I'll get my five minutes of fame for being first with a Dylan quotation. I was a bit slow because, unlike Jonah Lehrer, I wanted to check that the quotation actually exists.

Times Higher Education (THE) have announced that they will be introducing reforms to their World University Rankings and ending their partnership with media and data giant, Thomson Reuters (TR).

Exactly why is not stated. It could be rooted in financial disagreement. Maybe THE feels betrayed because TR let  US News use the reputation survey for their new Best Global Universities rankings. Perhaps THE got fed up with explaining why places like Bogazici University, Federico Santa Maria Technical University and Royal Holloway were world beaters for research impact, outshining Yale, Oxford and Cambridge,

The reputation survey will now be administered by THE itself in cooperation with Elsevier and will make use of the Scopus database. Institutional data will be collected  from universities, the Scopus database and the Scival analysis tool by a new THE team.

The coming months will reveal what THE have in store but for now this is a list of recommendations. No doubt there will be many more from all sorts of people.

Display each indicator separately instead of lumping them together into Teaching, Research and International Outlook. It is impossible to work out exactly what is causing a rise or fall in the rankings unless they are separated.

Try to find some why of reducing the volatility of the reputation survey. US News do this by using a five year average and  QS by rolling over unchanged responses for a further two years.

Consider including questions about undergraduate teaching or doing another survey to assess student satisfaction.

Reduce the weighting of the citations indicator and use more than one measure of citations to assess research quality (citations per paper), faculty quality (citations per faculty) and  research impact (total citations). Use field normalisation but sparingly and sensibly and forget about that regional modification.

Drop the Industry Income: Innovation indicator. It is unfair to liberal arts colleges and private universities and too dependent on input from institutions. Think about using patents instead.

Income is an input. Do not use unless it is to assess the efficiency of universities in producing research or graduates.

Considering dropping the international students indicator or at least reducing its weighting. It is too dependent on geography and encourages all sorts of immigration scams.

Benchmark scores against the means of a constant number of institutions. If you do not, the mean indicator scores will fluctuate from year to year causing all sorts of distortions.

The US News Arab Region Rankings

Hardly a week passes without the publication of yet more international university rankings. This week it was the Best Arab Region Universities from the US News, famous for producing America's Best Colleges for over three decades.

These rankings are research based. There are nine indicators, one of which measures the number of publications and has a weighting of 30 per cent. The other eight relate to citations in some way. There are no indicators measuring faculty student ratio, teaching quality, graduate employment,  income or reputation.

Inclusion in the rankings required 400 papers in the Scopus database over a five year period,2009 to 2013. It is a serious indictment of Arab universities that only 91 institutions could  reach this  modest target.

There is an interesting section in the methodology:

"Papers published by Arab region institutions in the subject area of physics and astronomy were excluded based on input from Elsevier's bibliometric experts, who determined that their citation characteristics would distort the results of the overall rankings. There is, however, a separate subject ranking for physics and astronomy that is based on papers published exclusively in those fields."
This presumably means that US News is aware of the distorting effect of physics publications with a large number of contributing authors, which has helped propel institutions such as Panjab University and Federico Santa Maris Technical University into high spots in the THE world rankings.

The rankings show that research in the Arab world is dominated by a few countries. Just over half of the universities in the rankings come from three countries, Egypt, Saudi Arabia and Algeria. However, at the very top the rankings are dominated by Saudi Arabia, which holds the first three places.

The Top Ten are:

1.  King Saud University, Saudi Arabia
2.  King Abdualaziz University, Saudi Arabia
3.  King Abdullah University of Science and Technology, Saudi Arabia
4.  Cairo University, Egypt
5.  American University of Beirut, Lebanon
6.  Mansoura University, Egypt
7.  Ain Shams University, Egypt
8   King Fahd University of Petroleum and Minerals, Saudi Arabia
9.  Alexandria University, Egypt
10. United Arab Emirates University

There are also 16 subject rankings. Every one of these is topped by a Saudi university except for the Social Sciences which is headed by the American University of Beirut. In first place in the Physics rankings is King Abdulaziz University which has benefited from those multi-contributor publications which feature at least one of its adjunct faculty with a double affiliation.

Universite Cadi Ayyad Marrakech, Morocco, which was declared by THE to be the best Arab university and best in Africa north of the Kalahari, is in thirtieth place here. I wonder why.

The Taiwan (NTU) Rankings

These rankings are entirely research based and make no attempt to measure teaching quality. They also have a very strong bias against the humanities and social sciences: the London School of Economics and the Stockholm School of Economics do not appear at all.

They tend to reward size rather than quality so that Johns Hopkins is in 2nd place and Caltech 36th. The emphasis on citations gives a boost to medical schools like the University of California San Francisco and Rockefeller University.

The results, with these limitations, are quite reasonable.

Initial Comments on the US News Global Rankings

It was a bit of a surprise when US News & World Report (USNWR) announced that they were going global but perhaps it  shouldn't have been. The USNWR has been ranking American colleges since the early 80s, making even  the Shanghai Centre for World Class Universities or QS look like novices. Also, with the advance of globalisation of higher education and research there is now a market for comparisons of US universities and their international competitors. 

The Best Global Universities rankings are research based, except for two indicators, each with a 5% weighting, that count Ph D degrees. They are also heavily citation oriented, with a huge 42.5% weighting going to citations. However, the US News staff have used their common sense and included four measures of citations, normalized citation impact, total citations, number of highly cited papers and percentage of highly cited papers.

The result of this is that many of the high fliers in this year's THE rankings are absent. Bogazici University in Turkey, 14th best in Asia according to THE, is absent, So is Federico Santa Maria Technical University in Chile, according to THE second best in Latin America and Panjab University, supposedly the second best in India.

The reason for this contrast is simply that THE and Thomson Reuters rewarded these institutions for a few physics papers with hundreds of participating institutions by using a very inappropriate methodology and giving it a 30% weighting. USNWR have trimmed this indicator to 10% and so the high fliers have been grounded.

The university rankings business gets bigger and bigger

US News is going global. There are three different Arab/ MENA rankings on the way. Now, QS is getting ready for further growth. This is from Education Investor.

Exclusive: QS seeks £10m investment

The university rankings provider QS is looking to sell a £10 million stake in its business, EducationInvestorunderstands.
According to its website, QS runs websites and events that connect graduates and employers. But it is best known for its World University Rankings, which it claims are “the most widely read university comparison of their kind”.
Three sources close to the matter said a deal was on the table, and one said that first round bids had already been submitted. QS wants to raise the cash “half to buy out an existing shareholding and half to use as growth capital”. 
However, Nunzio Quacquatelli, managing director and majority shareholder of QS, told EducationInvestorthat the firm was “looking at all options, both debt and possibly structured finance”. 
“We are looking for some external funding to support our rapid growth. Our vision is to be a leading information company in the higher education sector with global ambitions and [with this funding] we aim to continue on this path.”
QS operates in over 70 countries, and has more than 200 staff and 1,200 clients. Its valuation hasn’t been publicised, but the firm is understood to have an ebitda of £3.3 million and revenue of £19.8 million. 
According to one source, the deal is expected to complete later in the fourth quarter.

Shanghai without the Awards

Updated. The link to the site is here.

The Center for World-Class Universities (CWU) at Shanghai Jiao Tong University has produced an interesting new ranking by removing the Alumni and Awards indicators from its Academic Ranking of World Universities. These indicators have been criticised for allowing western universities to live off their intellectual capital and ignoring the rise of newcomers in Asia.

So what would ARWU look like without the Nobel and Fields awards?

At the very top things are the same. Harvard is still first and Stanford second. But Cambridge goes down and Oxford goes up.

Universities that would benefit significantly from deleting these indicators include Michigan, rising from 23rd  to 13th, Pennsylvania State University from 58th  to 35th, University of Florida, Tsinghua University, Alberta, Peking, Sao Paul, Tel Aviv, Zhejiang and Scuola Normale Pisa, which would rise to the 201-300 band.

CWU have calculated the ratio between places in ARWU and the Alternative Ranking. The higher the score the greater the benefit from the Awards and Alumni indicators. The biggest gainers from Nobel and Fields laureates are Princeton, Moscow State University and Paris Sud (11).

The countries that have benefited most from these indicators are the USA, France, Germany.

It looks as though the ARWU has favoured the Ivy League, continental European universities and Cambridge at the expense of American public universities and the rising stars of Asia.

Another Global Ranking

Just when you thought you could stop reading about rankings.

For several years the US News & World Report (USNWR), publishers of America's Best Colleges, repackaged the QS World University Rankings and just put its own stamp on them for the American public.

Now, the USNWR has announced that it is going into the global rankings business. It seems that this time that they will produce completely new rankings that have nothing to do with the Times Higher Education (THE) rankings. There will also be regional, country and subject rankings.

The data, however,will come from Thomson Reuters (TR), who are also the data providers for the THE world rankings and two of the indicators, Highly Cited Researchers and Publications, in the Shanghai ARWU rankings. It is definitely unhealthy if TR are going to supply the data or some of it for three out of four well known world rankings.

Bob Morse says that the new rankings will be "powered by Thomson Reuters InCitesTM research analytics solutions". Does this mean that universities who do not join InCites will not be ranked? Will universities be allowed to opt in or opt out? Will all data come from TR? Will the survey be shared with THE or will there be another one?

How to win citations and rise in the rankings

A large part of the academic world has either been congratulating itself on performing well in the latest Times Higher Education  (THE) world rankings, the data for which is provided by Thomson Reuters (TR), or complaining that only large injections of public money will keep their universities from falling into the great pit of the unranked.

Some, however, have been baffled by some of the placings reported by THE this year. Federico Santa Maria Technical University in Chile is allegedly the fourth best university in Latin America, Scuola Normale Superiore di Pisa the best in Italy and Turkish universities are apparently the rising stars of the academic world.

When there is a a university that appears to be punching above its weight the cause often turns out to be the citations indicator

Scuola Normale Superiore di Pisa is 63rd in the world with an overall score of 61.9 but a citations score of 96.4.

Royal Holloway, University of London is 118th in the world with an overall score of 53 but a citations score of 98.9

The University of California Santa Cruz is top of the world for citations with an overall score of 53.7 and 100 for citations

Bogazici University is 139th in the world with an overall score of 51.1 and a citations score of 96.8.

Federico Santa Maria Technical University in Valparaiso is in the 251-175 band so the total score is not given although it would be easy enough to work out. It has a score of 99.7 for citations.

So what is going on?

The problem lies with various aspects of Thomson Reuters' methodology.

First they use field normalisation. That means that they do not simply count the number of citations but compare the number of citations in 250 fields with the world average in each field. Not only that, but they compare each year in which the paper is cited with the world average of citations for that year.

The rationale for this is that the number  of citations and the rapidity with which papers are cited vary from field to field. A paper reporting a cure for cancer or the discovery of a new particle will be cited hundreds of times within weeks. A paper in philosophy, economics or history may languish for years before anyone takes notice. John Muth's work on rational expectations was hardly noticed or cited for years before eventually starting a revolution in economic theory. So universities should be compared to the average for fields and years. Otherwise, those that are strong in the humanities and social sciences will be penalised.

Up to a point this is not a bad idea. But it does assume that all disciplines are equally valuable and demanding. But if the world has decided that it will fund medical research or astrophysics and support journals and pay researchers to read and cite other researchers' papers rather than media studies or education, then this is perhaps something rankers and data collectors should take account of.

In any case, by normalising for so many fields and then throwing normalisation by year into the mix, TR increase the likelihood of statistical anomalies. If someone can get a few dozen citations within a couple of years after publication in a field where citations, especially early ones, average below one a year then this could give an enormous boost to a university's citation score. That is precisely what happened with Alexandria University in 2010. Methodological tweaking has mitigated the risk to some extent but not completely. A university could also get a big boost by getting credit, no matter how undeserved, for a breakthrough paper or a review that is widely cited.

So let's take a look at some of the influential universities in the 2014 THE rankings. Scuola Normale Superiore di Pisa (SNSP) is a small research intensive institution that might not even meet the criteria to be ranked by TR. Its output is modest, 2,407 publications in the Web of Science core collection between 2009 and 2013, although for a small institution that is quite good.

One of those publications is 'Observation of a new boson...' in Physics Letters B in September 2012, which has been cited 1,631 times.

The paper has 2,896 "authors", whom I counted by looking for semicolons in the "find" box, affiliated to 228 institutions. Five of them are from SNSP.

To put it crudely, SSNP is making an "authorship" contribution of 0.17 %  to the paper but getting 100% of the citation credit, as does every other contributor. Perhaps its researchers are playing a leading role in the Large Hadron Collider project or perhaps it has made a disproportionate financial contribution but TR provide no reason to think so.

The University of the Andes, supposedly the second best university in Latin America, is also a contributor to this publication, as is Panjab University, supposedly the second best institution in the Indian subcontinent.

Meanwhile, Royal Holloway, University of London has contributed to "Observation of a new particle...' in the same journal and issue. This has received 1,734 citations and involved  2,932 authors from 267 institutions, along with Tokyo Metropolitan University, Federico Santa Maria Technical University, Middle Eastern Technical University and Bogazici University.

The University of California Santa Cruz is one of 119 institutions that contributed to the 'Review of particle physics...'  2010 which has been cited 3,739 times to date. Like all the other contributors it gets full credit for all those citations.

It is not just the number of citations that boosts citation impact scores but also their occurrence within a year or two of publication so that the number of citations is much greater than the average for that field and those years.

The proliferation of papers with hundreds of authors is not confined to physics. There are several examples from medicine and genetics as well.

At this point, the question arises why not divide the citations for each paper among the authors of the paper? This is an option available in the Leiden Ranking so it should not be beyond TR's technical capabilities.

Or why not stop counting multi - authored publications when they exceed a certain quota of authors? This is exactly what TR did earlier this year when collecting data for its new highly cited researchers lists. Physics papers with more than 30 institutional affiliations were omitted, a very sensible procedure that should have been applied across the board.

So basically, one route to success in the rankings is to get into a multi - collaborator mega - cited project.

But that is not enough in itself. There are hundreds of universities contributing to these publications. But not all of them  reap such disproportionate benefits. It is important not to publish too much. A dozen LHC papers will do wonders if you publish 400 or 500  papers a year. Four thousand a year and it will make little difference. One reason for the success of otherwise obscure institutions is that the number of papers by which the citations are divided is small.

So why on earth are TR using a method that produces such laughable results? Lets face it, if any other ranker put SNS Pisa, Federico Santa Maria or Bogaziii at the top of its flagship indicator we would go deaf from the chorus of academic tut-tutting.

TR, I suspect, are doing this because this method is identical or nearly identical to that used for their InCites system for evaluating individual academics within institutions, which appears very lucrative, and they do not want the expense and inconvenience of recalculating data.

Also perhaps, TR have become so enamoured of the complexity and sophistication of their operations that they really do think that they have actually discovered pockets of excellence in unlikely places that nobody else has the skill or the resources to even notice.

But we have not finished. There is one  more element in TR's distinctive methodology and that is its regional modification introduced by Thompson Reuters in 2011.

This means that the normalised citation impact score of the university is divided by the square root of the impact score of  the country in which it is located. A university located in a low scoring country will get a bonus that will be greater the lower the country's impact score. This would clearly be an advantage to countries like Chile, India and Turkey.

Every year there are more multi - authored multi -cited papers. It would not be surprising if university presidents start scanning the author lists of publications like the Review of Particle Physics, send out recruitment letters and get ready for ranking stardom.

Scuola Normale Superiore di Pisa: Are they dancing in the streets?

There is a lot of coverage of that huge pocket of excellence in Italy at ROARS:Return on Academic Research. Still trying to make sense of the Google translator.

The university with more research influence than.....

With apologies to the Sydney Morning Herald which had a headline about Caltech.

I don't know if the people of Valparaiso are aware that they are home to a world- class university but if they do find out this might be a nice headline.

Federico Santa Maria Technical University. More research influence than Princeton, Stanford, Harvard, Oxford, Cambridge, Yale, Duke, Bogazici, Colorado School of Mines.... (insert as you wish.)

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.

What good is reputation?

There is an excellent analysis by Alex Usher of Higher Education Strategy Associates of the reputation indicators in the THE and QS world rankings.

Main points include:

  • THE and QS are both insufficiently transparent about their reputation surveys and it is very difficult to judge their reliability. 

  • The numbers responding to the THE survey are very small outside the top 50 and this could cause substantial changes in total scores because of a small increase or decease in the number of votes.

  • The lack of transparency is influenced by commercial motives.
THE has been dropping twitter hints about interesting changes in the forthcoming rankings. Are these due to swings in the votes on the surveys?

 Or could it be the Large Hadron Collider Citation Amplifier?
