Never mind the rankings, THE has a huge database



There has been a debate, or perhaps the beginnings of a debate, about international university rankings following the publication of Bahram Bekhradnia's report to the Higher Education Policy Institute with comments in University World News by Ben SowterPhil BatyFrank Ziegele and Frans van Vought  and Philip Altbach and Ellen Hazelkorn and a guest post by Bekhradnia in this blog.

Bekhradnia argued that global university rankings were damaging and dangerous because they encourage an obsession with research, rely on unreliable or subjective data, and emphasise spurious precision. He suggests that governments, universities and academics should just ignore the rankings.

Times Higher Education (THE) has now published a piece by THE rankings editor Phil Baty that does not really deal with the criticism but basically says that it does not matter very much because the THE database is bigger and better than anyone else's. This he claims is "the true purpose and enduring legacy" of the THE world rankings.

Legacy? Does this mean that THE is getting ready to abandon rankings, or maybe just the world rankings, and go exclusively into the data refining business? 

Whatever Baty is hinting at, if that is what he is doing, it does seem a rather insipid defence of the rankings to say that all the criticism is missing the point because they are the precursor to a big and sophisticated database.

The article begins with a quotation from Lydia Snover, Director of Institutional Research, at MIT:

“There is no world department of education,” says Lydia Snover, director of institutional research at the Massachusetts Institute of Technology. But Times Higher Education, she believes, is helping to fill that gap: “They are doing a real service to universities by developing definitions and data that can be used for comparison and understanding.”

This sounds as though THE is doing something very impressive that nobody else has even thought of doing. But Snover's elaboration of this point in an email gives equal billing to QS and THE as definition developers and suggests the definitions and data that they provide will improve and expand in the future, implying that they are now less than perfect. She says:

"QS and THE both collect data annually from a large number of international universities. For example, understanding who is considered to be “faculty” in the EU, China, Australia, etc.  is quite helpful to us when we want to compare our universities internationally.  Since both QS and THE are relatively new in the rankings business compared to US NEWS, their definitions are still evolving.  As we go forward, I am sure the amount of data they collect and the definitions of that data will expand and improve."

Snover, by the way , is a member of 
the QS advisory board, as is THE's former rankings  "masterclass" partner, Simon Pratt.

Baty offers a rather perfunctory defence of the THE rankings. He talks about rankings bringing great insights into the shifting fortunes of universities. If we are talking about year to year changes then the fact that THE purports to chart shifting fortunes is a very big bug in their methodology. Unless there has been drastic restructuring universities do not change much in a matter of months and any ranking that claims that it is detecting massive shifts over a year is simply advertising its deficiencies.

The assertion that the THE rankings are the most comprehensive and balanced is difficult to take seriously. If by comprehensive it is meant that the THE rankings have more indicators than QS or Webometrics that is correct. But the number of indicators does not mean very much if they are bundled together and the scores hidden from the public and if some of the indicators, the teaching survey and research survey for example, correlate so closely that they are effectively the same thing. In any case, The Russian Round University Rankings have 20 indicators compared with THE's 13 in the world rankings.

As for being balanced, we have already seen Bekhradnia's analysis showing that even the teaching and international outlook criteria in the THE rankings are really about research. In addition, THE gives almost a third of its weighting to citations. In practice that is often even more because the effect of the regional modification, now applied to half the indicator, is to boost in varying degrees the scores of everybody except those in the best performing country. 

After offering a scaled down celebration of the rankings, Baty then dismisses critics while announcing that THE "is quietly [seriously?] getting on with a hugely ambitious project to build an extraordinary and truly unique global resource." 


Perhaps some elite universities, like MIT, will find the database and its associated definitions helpful but whether there is anything extraordinary or unique about it remains to be seen.

Searching for the Gold Standard: The Times Higher Education World University Rankings, 2010-2014


Now available at the Asian Journal of University Education. The paper has, of course, already been outdated by subsequent developments in the world of university rankings


ABSTRACT

This paper analyses the global university rankings introduced by Times Higher Education (THE) in partnership with Thomson Reuters in 2010 after the magazine ended its association with its former data provider Quacquarelli Symonds. The distinctive features of the new rankings included a new procedure for determining the choice and weighting of the various indicators, new criteria for inclusion in and exclusion from the rankings, a revised academic reputation survey, the introduction of an indicator that attempted to measure innovation, the addition of a third measure of internationalization, the use of several indicators related to teaching, the bundling of indicators into groups, and most significantly, the employment of a very distinctive measure of research impact with an unprecedentedly large weighting. The rankings met with little enthusiasm in 2010 but by 2014 were regarded with some favour by administrators and policy makers despite the reservations and criticisms of informed observers and the unusual scores produced by the citations indicator. In 2014, THE announced that the partnership would come to an end and that the magazine would collect its own data. There were some changes in 2015 but the basic structure established in 2010 and 2011 remained intact.

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.

Is Trump keeping out the best and the brightest?


One of the strange things among several about the legal challenge to Trump's executive order on refugees and immigration is the  claim in an amicus brief by dozens of companies, many of them at the cutting edge of the high tech economy,  that the order makes it hard to "recruit hire and retain some of the world's best employees." The proposed, now frozen, restrictions would, moreover, be a "barrier to innovation" and prevent companies from attracting "great talent." They point out that many Nobel prize winners are immigrants.

Note that these are "tech giants", not meat packers or farmers and that they are talking about the great and the best employees, not the good or adequate or possibly employable after a decade of ESL classes and community college.

So let us take a look at the seven countries included in the proposed restrictions. Are they likely to be the source of large numbers of future hi tech entrepreneurs, Nobel laureates and innovators?

The answer is almost certainly no. None of the Nobel prize winners (not counting Peace and Literature) so far have been born in Yemen, Iraq, Iran, Somalia, Sudan, Libya or Syria although there has been an Iranian born winner of the Fields medal for mathematics.

The general level of the higher educational system in these countries does not inspire confidence that they are bursting with great talent. Of the seven only Iran has any universities in the Shanghai rankings, the University of Tehran and Amirkabir University of Technology.

The Shanghai rankings are famously selectively so take a look at the rank of the top universities in the Webometrics rankings which are the most inclusive, ranking more than 12,000 institutions this year.

The position of the top universities from the seven countries is as follows:

University of Babylon, Iraq 2,654
University of Benghazi, Libya  3,638
Kismayo University, Somalia 5,725
University of Khartoum, Sudan   1,972
Yemeni University of Science and Technology 3,681
Tehran University of Medical Science, Iran 478
Damascus Higher Institute of Applied Science and Technology, Syria 3,757.

It looks as though the only country remotely capable of producing innovators, entrepreneurs and scientists is Iran.

Finally, let's look at the scores of students from these countries n the GRE verbal and quantitative tests 2011-12.

For verbal reasoning, Iran has a score of  141.3, Sudan 140.6, Syria 142.7, Yemen 141, Iraq 139.2, and Libya 137.1. The mean score is 150.8 with a standard deviation of 8.4.

For quantitative reasoning,  Iran has a score of 157.5, equal to France, Sudan 148.5, Syria 152.7, Yemen 148.6, Iraq 146.4, Libya 145.5. The mean score is 151.4 with a standard deviation of 8.7.

It seems that of the seven countries only Iran is likely to produce any significant numbers of workers capable of contributing to a modern economy.

No doubt there are other reasons why Apple, Microsoft and Twitter should be concerned about Trump's executive order. Perhaps they are worried about Russia, China, Korea or Poland being added to the restricted list. Perhaps they are thinking about farmers whose crops will rot in the fields, ESL teachers with nothing to do or social workers and immigration lawyers rotting at their desks. But if they really do believe that Silicon Valley will suffer irreparable harm from the proposed restrictions then they are surely mistaken.

Guest post by Bahram Bekhradnia

I have just received this reply from Bahram Bekhradnia, President of the Higher Education Policy institute, in response to my review of his report on global university rankings.

My main two points which I think are not reflected in your blog – no doubt because I was not sufficiently clear – are
·       First the international rankings – with the exception of U-multirank which has other issues – almost  exclusively reflect research activity and performance. Citations and publications of course are explicitly concerned with research, and as you say “International faculty are probably recruited more for their research reputation than for anything else. Income from industry (THE) is of course a measure of reported funding for applied research. The QS academic reputation survey is officially about research and THE 's academic reputation survey of teaching is about postgraduate supervision.”  And I add (see below) that faculty to student ratios reflect research activity and are not an indicator of a focus on education.  There is not much argument that indicators of research dominate the rankings.
Yet although they ignore pretty well all other aspects of universities’ activities they claim nevertheless to identify the "best universities". They certainly do not provide information that is useful to undergraduate students, nor even actually to postgraduate students whose interest will be at discipline not institution level. If they were also honest enough to say simply that they identify research performance there would be rather less objection to the international rankings.

That is why it is so damaging for universities, their governing bodies – and even Governments – to pay so much attention to improving their universities performance in the international rankings.  Resources – time and money - are limited and attaching priority to improving research performance can only be right for a very small number of universities.

·     Second, the data on which they are based are wholly inadequate.  50% of the QS and 30% of the Times Higher rankings are based on nothing more than surveys of "opinion”, including in the case of QS the opinions of dead respondents.  But no less serious is that the data on which the rankings are based – other than the publications and prize related data – are supplied by universities themselves and unaudited, or are ‘scraped’ from a variety of other sources including universities websites’ and cannot be compared one with the other. Those are the reasons for the Trinity College Dublin and Sultan Qaboos fiascos.  One UAE university told me recently they had (mistakenly) submitted information about external income in UAE Dirhams instead of US Dollars – an inflation of 350% that no-one had noticed.  Who knows what other errors there may be – the ranking bodies certainly don’t. 
In reply to some of the detailed points that you make
In order to compare institutions you need to be sure that the data relating to each are compiled on a comparable basis, using comparable definitions et cetera. That is why the ranking bodies, rightly, have produced their own data definitions to which they ask institutions to adhere when returning data. The problem of course is that there is no audit of the data that are returned by institutions to ensure that the definitions are adhered to or that the data are accurate.  Incidentally, that is why also there is far less objection to national rankings, which can, if there are robust national data collection and audit arrangements, have fewer problems with regard to comparability of data.
But at least there is the attempt with institution-supplied data to ensure that they are on a common basis and comparable.  That is not so with data ‘scraped’ from random sources, and that is why I say that data scraping is such a bad practice.  It produces data which are not comparable, but which QS nevertheless uses to compare institutions. 
You say that THE, at least, omit faculty on research only contracts when compiling faculty to student ratios.  But when I say that FSRs are a measure of research activity I am not referring to research only faculty.  What I am pointing out is that the more research a university does the more academic faculty it is likely to recruit on teaching and research contracts.  These will inflate the faculty to student ratios without necessarily increasing the teaching capacity over a university that does less research, consequently has fewer faculty but whose faculty devote more of their time to teaching.  And of course QS even includes research contract faculty in FSR calculations.  FSRs are essentially a reflection of research activity.

Getting satisfaction: look for universities that require good A level grades

If you are applying to a British university and you are concerned not with personal transformation, changing your life or social justice activism but with simple things like enjoying your  course and finishing it and getting a job what would you look for? Performance in global rankings? Staff salaries? Spending? Staff student ratios?

Starting with student satisfaction, here are a few basic correlations between scores for overall student satisfaction on the Guardian UK rankings and a number of variables from the Guardian rankings, the Times Higher Education TEF simulation (THE), the Hefce survey of educational qualifications, and theTHE survey of vice-chancellor's pay.


Average Entry Tariff (Guardian)   .479**
Staff student ratio (Guardian) .451**
Research Excellence Framework score (via THE)  .379**
Spending per student (Guardian)  .220 *
Vice chancellor salary (via THE) .167
Average salary (via THE) .031
Total staff (via THE) .099
Total students (via THE) .065
Teaching qualifications (Hefce)  -161 (English universities only)

If there is one single thing that best predicts how satisfied you will be it is average entry tariff (A level grades). The number of staff compared to students, REF score, and spending per student also correlate significantly with student satisfaction.

None of the following are of any use in predicting student satisfaction: vice chancellor salary, average staff salary,  total staff,  total students or percentage of faculty with teaching qualifications.

Comments on the HEPI Report

The higher education industry tends to respond to global rankings in two ways. University bureaucrats and academics either get overexcited, celebrating when they are up, wallowing in self-pity when down, or they reject the idea of rankings altogether.

Bahram Bekhradnia of the Higher Education Policy Institute in the UK has  published a report on international rankings which adopts the second option. University World News has several comments including a summary of the report by Bekhradnia.

To start off, his choice of rankings deserves comment. He refers to the "four main rankings", Academic Ranking of World Universities (ARWU) from Shanghai, Quacquarelli Symonds (QS), Times Higher Education (THE) and U- Multirank. It is true that the first three are those best known to the public, QS and Shanghai by virtue of their longevity and THE because of its skilled branding and assiduous cultivation of the great, the good and the greedy of the academic world. U- Multirank is chosen presumably because of its attempts to address, perhaps not very successfully, some of the issues that the author discusses.

But focusing on these four gives a misleading picture of the current global ranking scene. There are now several rankings that are mainly concerned with research -- Leiden, Scimago, URAP, National Taiwan University, US News -- and redress some of the problems with the Shanghai ranking by giving due weight to the social sciences and humanities, leaving out decades old Nobel and Fields laureates and including more rigorous markers of quality. In addition, there are rankings that measure web activity, environmental sustainability, employability and innovation. Admittedly, they do not do any of these very well but the attempts should at least be noted and they could perhaps lead to better things.

In particular, there is now an international ranking from Russia, Round University Ranking (RUR), which could be regarded as an improved version of the THE world rankings and which tries to give more weight to teaching, It uses almost the same array of metrics as THE plus some more but with rational and sensible weightings, 8% for field normalised citations, for example, rather than 30%.

Bekhradnia has several comments on the defects of current rankings. First, he says that they are concerned entirely or almost entirely with research. He claims that there are indicators in the QS and THE rankings that are actually although not explicitly about research. International faculty are probably recruited more for their research reputation than for anything else. Income from industry (THE) is of course a measure of reported funding for applied research. The QS academic reputation survey is officially about research and THE 's academic reputation survey of teaching is about postgraduate supervision.

Bekhradnia is being a little unfair to THE. He asserts that if universities add to their faculty with research-only staff this will add to their faculty student metric, supposedly a proxy for teaching quality, thus turning the indicator into a measure of research. This is true of QS but it appears that THE does require universities to list research staff separately and excludes them from some indicators as appropriate. In any case, the number of research only staff is quite small outside the top hundred or so for most universities 

It is true that most rankings are heavily, perhaps excessively, research-orientated but it would be a mistake to conclude that this renders them totally useless for evaluating teaching and learning. Other things being equal, a good record for research is likely to be associated with positive student and graduate outcomes such as satisfaction with teaching, completion of courses and employment.

For English universities the Research Excellence Framework (REF) score is more predictive of student success and satisfaction, according to indicators in the Guardian rankings and the recent THE Teaching Excellence Framework simulation than the percentage of staff with educational training or certification, faculty salaries or institutional spending, although it is matched by staff student ratio.

If you are applying to English universities and you want to know how likely you are to complete your course or be employed after graduation, probably the most useful things to  know are average entry tariff (A levels), staff student ratio and faculty scores for the latest REF. There are of course intervening variables and the arrows of causation do not always fly in the same direction but scores for research indicators are not irrelevant to comparisons of teaching effectiveness and learning outcomes.

Next, the report deals with the issue of data, noting that internal data checks by THE and QS do not seem to be adequate. He refers to the case of Trinity College Dublin where a misplaced decimal point caused the university to drop several places in the THE word rankings. He then goes on to criticise QS for "data scraping" that is getting information from any available source. He notes that they caused Sultan Qaboos University (SQU) to drop 150 places in their world rankings apparently because QS took data from the SQU website that identified non teaching staff as teaching. I assume that the staff in question were administrators: if they were researchers then it would not have made any difference.

Bekhradnia is correct to point out that data from web sites is often incorrect or subject to misinterpretation. But to assume that such data is necessarily inferior to that reported by institutions to the rankers is debatable. QS has no need to be apologetic about resorting to data scraping. On balance information about universities is more likely to be correct if it comes from one of several and similar competitive sources, if it is from a source independent of the ranking organisation and the university, if it has been collected for reasons other than submission to the rankers, or if there are serious penalties for submitting incorrect data.

The best data for university evaluation and comparison is likely to be from third party databases that collect masses of information or from government agencies that require accuracy and honesty. After that institutional data from web sites and the like is unlikely to be significantly worse  than that specifically submitted for ranking purposes.

There was an article in University World News in which Ben Sowter of QS took a rather defensive position with regard to data scraping. He need not have done so. In fact it would not be a bad idea for QS and others to do a bit more.

Bekhradnia goes on to criticise the reputation surveys. He notes that recycling unchanged responses over a period of five years, originally three, means that it is possible that QS is counting the votes of dead or retired academics. He also points out that the response rate to the surveys is very low. All this is correct although it is nothing new. But it should be pointed out that what is significant is not how many respondents there are but how representative they are of the group that is being investigated. The weighting given to surveys in the THE and QS rankings is clearly too much and QS's  methods of selecting respondents are rather incoherent and can produce counter-intuitive results such as extremely high scores for some Asian and Latin American universities.

However, it is going too far to suggest that surveys should have no role. First reputation and perceptions are far from insignificant. Many students would, I suspect, prefer to go a university that is overrated by employers and professional schools than to one that provides excellent instruction and facilities but has failed to communicate this to the rest of the world.

In addition, surveys can provide a reality check when a university does a bit of gaming. For example King Abdulaziz University (KAU) has been diligently offering adjunct contracts to dozens of highly cited researchers around the world that require them to put the university as a secondary affiliation and thus allow it to get huge numbers of citations. The US News Arab Region rankings have KAU in the top five among Arab universities for a range of research indicators, publications, cited publications, citations, field weighted citation impact, publications in the top 10 % and the top 25%. But its academic reputation rank was only 26, definitely a big thumbs down.

Bekhradnia then refers to the advantage that universities get in the ARWU rankings simply by being big. This is certainly a valid point. However, it could be argued that quantity is a necessary prerequisite to quality and enables the achievement of economies of scale. 

He also suggest that the practice of presenting lists in order is  misleading since a trivial difference in the raw data could mean a substantial difference in the presented ranking. He proposes that it would be better to group universities into bands. The problem with this is that when rankers do resort to banding, it is fairly easy to calculate an overall score by adding up the published components. Bloggers and analysts do it all the time.

Bekhradnia concludes:
"The international surveys of reputation should be dropped
– methodologically they are flawed, effectively they only
measure research performance and they skew the results in
favour of a small number of institutions."

This is ultimately self defeating. The need and the demand for some sort of  ranking is too widespread to set aside. Abandon explicit rankings and we will probably have implicit rankings of recommendations by self declared experts.

There is much to be done to make rankings better. The priority should be finding objective and internationally comparable measures of student attributes and attainment. That will be some distance in the future. For the moment what universities should be doing is to focus not on composite rankings but on the more reasonable and reliable indicators within specific rankings. 

Bekhradnia does have a very good point at the end:

"Finally, universities and governments should discount therankings when deciding their priorities, policies and actions.In particular, governing bodies should resist holding seniormanagement to account for performance in flawed rankings.Institutions and governments should do what they do becauseit is right, not because it will improve their position in therankings."

I would add that universities should stop celebrating when they do well in the rankings. The grim fate of Middle East Technical University should be present in the mind of every university head.

What's Wrong with Ottawa?

The University of Ottawa (UO) has been a great success over the last few years, especially in research. In 2004 it was around the bottom third of the 202-300 band in the Shanghai Academic Ranking of World Universities. By 2016 it had reached the 201st place, although the Shanghai rankers still recorded it as being in the 201-300 band. Another signing of a highly cited researcher, another paper in Nature, a dozen more papers listed in the Science Citation Index and it would have made a big splash by breaking into the Shanghai top 200.

The Shanghai rankings have, apart from recent problems with the Highly Cited Researchers indicator, maintained a stable methodology so this is a very solid and remarkable achievement.

A look at the individual components of these rankings shows that UO has improved steadily in the the quantity and the quality of research. The score for publications rose from 37.8 to 44.4 between 2004 and 2016, from 13.0 to 16.1 for papers in Nature and Science, and from 8.7 to 14.5 for highly cited researchers (Harvard is 100 in all cases). For productivity (five indicators divided by number of faculty) the score went from 13.2 to 21.5 (Caltech is 100).

It is well known that the Shanghai rankings are entirely about research and ignore the arts and humanities. The Russian Round University Rankings (RUR), however, get their data from the same source as THE did until two years ago, include data from the arts and humanities, and have a greater emphasis on teaching related indicators.

In the RUR rankings, UO rose from 263rd place in 2010 to 211th overall in 2015, from 384th to 378th in five combined teaching indicators and from 177th to 142nd in five combined research indicators. Ottawa is doing well for research and and creeping up a bit for teaching related criteria, although the relationship between these and actual teaching may be rather tenuous.

RUR did not rank UO in 2016. I cannot find any specific reason  but it is possible that the university did not submit data for the Institutional Profiles at Research Analytics.

Just for completeness, Ottawa is also doing well in the Webometrics ranking, which is mainly about web activity but does include a measure of research excellence. It is in the 201st spot there also.

It seems, however, that this is not good enough. In September, according to Fulcrum, the university newspaper, there was a meeting of the Board of Governors which discussed not the good results from RUR, Shanghai Ranking and Webometrics. but a fall in the Times Higher Education (THE) World University Rankings from the 201-250 band in 2015-16 to the 250-300 band in 2016-17. One board member even suggested taking THE to court.

So what happened to UO in last year's THE world rankings? The only area where it fell was for Research, from 36.7 to 21.0. In the other indicators or indicator groups, Teaching, Industry Income, International Orientation, Research Impact (citations), it got the same score or improved.

But this is not very helpful. There are actually three components in the research group of indicators, which has a weighting of 30%, two of which are scaled. A fall in the research component might be caused by a fall in its score for research reputation, a decline in its reported research income, a decline in the number of publications, a rise in the number of academic staff, or some combination of these.

The fall in UO's research score could not have been caused by more faculty. The number of full time faculty was 1,284 in 2012-13 and 1,281 in 2013-14.

There was a fall of 7.6% in Ottawa's "sponsored research income" between 2013 and 2014 but I am not sure if that is enough to produce such a large decline in the combined research indicators.

My suspicion is -- and until THE disaggregate their indicators it cannot be anything more  -- that the problem lies with the 18% weighted survey of postgraduate teaching. Between 2015 and 2016 the percentage of survey respondents from the arts and humanities was significantly reduced while that from the social sciences and business studies was increased. This would be to the disadvantage of English speaking universities, including those in Canada, relatively strong in the humanities and to the advantage of Asian universities relatively strong in business studies. UO, for example, is ranked highly by Quacquarelli Symonds (QS) for English, Linguistics and Modern Languages, but not for Business Management Studies and Finance and Accounting.

This might have something to do with THE wanting to get enough respondents for business studies after they had been taken out of the social sciences and given their own section. If that is the case, Ottawa might get a pleasant surprise this year since THE are now treating law and education as separate fields and may have to find more respondents to get around the problem of small sample sizes. If so, this could help UO which appears to be strong in those subjects.

It seems, according to another Fulcrum article, that the university is being advised by Daniel Calto from Elsevier. He correctly points out that citations had nothing to do with this year's decline. He then talks about the expansion in the size of the rankings with newcomers pushing in front of UO. It is unlikely that this in fact had a significant effect on the university since most of the newcomers would probably enter below the 300 position and since there has been no effect on its score for teaching, international orientation, industry income or citations (research impact).

I suspect that Caito may have been incorrectly reported. Although he says it was unlikely that citations could have had anything to do with the decline, he is reported later in the article to have said that THE's exclusion of kilo-papers (with 1,000 authors) affected Ottawa. But the kilo-papers were excluded in 2015 so that could not have contributed to the fall between 2015 and 1016.

The Fulcrum article then discusses how UO might improve. M'hamed Aisati, a vice-president at Elsevier, suggest getting more citations. This is frankly not very helpful. The THE methodology means that more citations are meaningless unless they are concentrated in exactly the right fields. And if more citations are accompanied by more publications then the effect could be counter-productive.

If UO is concerned about a genuine improvement in research productivity and quality there are now several global rankings that are quite reasonable. There are even rankings that attempt to measure  things like innovation, teaching resources, environmental sustainability and web activity.

The THE rankings are uniquely opaque in that they hide the scores for specific indicators, they are extremely volatile, they depend far too much on dodgy data from institutions and reputation surveys that can be extremely unstable. Above all, the citations indicator is a hilarious generator of absurdity.

The University of Ottawa, and other Canadian universities, would be well advised to forget about the THE rankings or at least not take them so seriously.
