Should UK Research Funding Be Reorganized?

Posted in Finance, Science Politics with tags , , , , , , , , , , on April 13, 2013 by telescoper

A couple of recent news items spurred me on to reflect a bit about the system of research funding in the UK. The first of these was an item I noticed a while ago in Research Fortnight about the (ongoing) Triennial Review of the research councils, and specifically, input from the Wellcome Trust to that review that was rather critical of the Science and Technology Facilities Council and suggested it might be dismantled.

For context it’s probably a good idea to look back to the formation of STFC in 2007 via the merger of the Particle Physics and Astronomy Research Council (PPARC) and the Council for the Central Laboratories of the Research Councils (CCLRC). Previously, PPARC had looked after particle physics and astronomy (including space science) and CCLRC had run large experimental facilities in other branches of science. The idea of merging them wasn’t silly. A large chunk of PPARC’s budget went on managing large facilities, especially ground-based astronomical observatories, and it was probably hoped that it would be more efficient to put all these big expensive pieces of kit under the same roof (so to speak).

However, at the time, there was considerable discussion about what should happen in general with science grants. For example, physicists working in UK universities in areas outside astronomy and particle physics previously obtained research grants from the Engineering and Physical Sciences Research Council (EPSRC), along with chemists, engineers and even mathematicians. Some experimentalists working in these areas used facilities run by the CCLRC to do their work. However, astronomers and particle physicists got their grants from PPARC, the same organisation that ran their facilities and also paid subscriptions to international agencies such as CERN and ESA. These grants were often termed “exploitation”  or “responsive mode” grants; they involved funding for postdoctoral researchers and staff time used in analysing observational or experimental data and comprised relatively little money compared the the cost of the PPARC facilities themselves. PPARC also funded PhD studentships and postdoctoral fellowships under the umbrella of its Education and Training division, although needless to say all the Education and Training involved was done in host universities, not by PPARC itself.

The question was whether the new merged organisation, STFC should continue giving grants to university groups or whether the responsibility for doing this should be moved elsewhere, perhaps to EPSRC. At the time, most astronomers were keen to have their research grants administered by the same organisation that ran the facilities. I thought it made more sense to have research scientists all on the same footing when it came to funding and in any case thought there were too many absurd divisions between, say, general relativity (EPSRC) and relativistic astrophysics (PPARC), so I was among the (relatively few) dissenting voices at the time.

There were other reasons for my unease. One was that, during a previously funding squeeze, PPARC had taken money from the grants line (the pot of money used for funding research groups) in order to balance the books, necessarily reducing the amount of science being done with its facilities. If STFC decided to do this it would probably cause even more pain, because grants would be an even smaller fraction of the budget in STFC than they were in PPARC. Those EPSRC physicists using CCLRC facilities seem to have managed pretty well so I didn’t really see the argument for astronomy and particle physics being inside STFC.

The other reason for me wanting to keep research grants out of STFC was that the (then) new Chief Executive of PPARC, Keith Mason, had made no secret of the disdain he felt towards university-based astronomy groups and had stated on a number of occasions his opinion that there were too many astronomers in the United Kingdom. There are two flaws with this argument. One is that astronomy is essential to the viability of many physics departments because of its appeal to potential students; without it, many departments will fold. The other problem is that Mason’s claim that the number of astronomers had grown by 40% in a few years was simply bogus.  This attitude convinced me that he in particular would need only the slightest excuse to divert funds away from astronomy into areas such as space exploration.

It all seems a very distant memory now, but six or years ago UK physics (including astronomy) was experiencing a time of relative plenty. The government had introduced a system whereby the research councils would fund research groups on the basis of the Full Economic Cost of the research, which meant more money coming into research groups that were successful at winning grants. The government increased funding for the councils to pay for this largesse and probably diminished the fear of another funding pinch. Astronomers and particle physicists also felt they would have more influence over future strategy in facility development by remaining within the same organisation. In the end what happened was that STFC not only kept the portfolio of astronomy and particle physics grants, but also acquired responsibility for nuclear physics from EPSRC.

But then, in 2007, just after STFC came into existence,  a major financial disaster broke: that year’s comprehensive spending review left the newly formed STFC with a huge gap in its finances. I don’t know why this happened but it was probably a combination of gross incompetence on behalf of the STFC Executive and deliberate action by persons higher up in the Civil Service. The subsequent behaviour of the Chief Executive of STFC led to a public dressing down by the House of Commons Select Committee and a complete loss of confidence in him by the scientific community. Miraculously, he survived, at least for a while. Unfortunately, so did the financial problems that are his legacy.

I don’t like to say I told you so, but that’s exactly what I am going to dp. Everything that happened was predictable given the initial conditions. You might argue that STFC wasn’t to know about the global economic downturn.As a matter of fact I’d agree. However, the deep cuts in the science budget we have seen have very little to do with that. They all stem from the period before the Credit Crunch even started. Although Prof. Mason was eventually replaced (in 20111), the problems inherent in STFC are far from solved.

The last Comprehensive Spending Review (2010) was less bad for STFC than some of us feared – with a level cash settlement which still holds. In real times the funds are now being eroded rather than being slashed further, but the situation remains very difficult because of past damage. I don’t think STFC  can afford to settle for flat cash at the next spending review. The new Supreme Leader  Chief Executive of STFC, John Womersley, said much the same thing at last night’s RAS dinner, in fact.

I know this preamble has been a bit long-winded, but I think it’s necessary to see the background to what I’m going to propose. These are the steps I think need to be taken to put UK physics back on track.

First, the powers that be have to realize that university researchers are not just the icing on the cake when it comes to science: they actually do most of the science. I think the new regime at STFC recognizes this, but I’m not sure the government does. Another problem is that  that the way scientists are supported in their research is a complete mess. It’s called the dual support system, because the research councils pay 80% of the cost of research grants and Higher Education Funding Councils (i.e. HEFCE in England) are meant to provide the other 20%. But in reality it is a bureaucratic nightmare that subjects researchers to endless form-filling and costs hundreds of millions in wasteful duplication. This was true enough of the old Research Assessment Exercise, but has been taken to even higher levels of absurdity by the forthcoming Research Excellence Framework, the decisions coming out of which will be more influencing by guesswork and institutional game-playing than actual research excellence.

The Research Councils already have well-managed systems to judge the quality of research grant applications, so do we really needed the REF on top of them?  The second article I referred to in the introduction, on a study showing that Research Council grant income, appeared in last week’s Times Higher. That study shows -at least at institutional level – that the two streams are pretty closely correlated. While REF/RAE income is awarded on a retrospective basis, and grant awards are based on proposals of future activity, it should be a surprise that people with a good track-record are also good at thinking up interesting new projects. Moreover, panels such as the STFC Astronomy Grant Panel (of which I am a member) certainly take into account the applicants’ track-record when assessing the viability of research proposals.

So if we don’t need two systems, what could we have instead? Moving grants from STFC to EPSRC, as some proposed in the past,  would go part of the way, but EPSRC has many problems too. I would therefore prefer to see a new organisation, specifically intended to fund blue-skies scientific research in universities. This organisation would have a mission statement that  makes its remit clear, and it would take over grants, studentships and fellowships from STFC, EPSRC and possibly some of the other research councils, such as NERC.  The new outfit would need a suitable acronym, but I can’t think of a good one at the moment. Answers on a postcard.

As a further suggestion,  I think there’s a strong case to be made that HEFCE should be deprived of its responsibility for research funding. The apparatus of research assessment it uses is obviously  flawed, but why is it needed anyway? If the government believes that research is essential to universities, its policy on selectivity doesn’t make any sense. On the other hand, if it believes that university departments don’t need to be research groups then why shouldn’t the research funding element be administered by a reserch organisation? Even better, a new University Research Council along the lines I have suggested  could fund research at 100% of the Full Economic Cost instead of only 80%. The substantial cash saved by scrapping the REF should be pumped into grants to be administered by the new organisation, reversing the  cuts imposed we’ve endured over past years.

So what should  STFC become after the Triennial Review? Clearly there is still a role for an organisation to manage large experimental facilities. However, the fact that the UK now has its own Space Agency means that some activity has already been taken out of the STFC remit.  The CERN and ESO subscriptions could continue to be managed by STFC along with other facilities, and it could in some cases commission projects in university research groups or industrial labs as it does now. Astronomers and particle physicists would continue to sit on its Board.  However, its status would change radically, in that it would become an organisation whose job is to manage facilities, not research. The tail will no longer be wagging the dog.

I very much doubt if these suggestions are at all in line with current political “thinking” nor with those of many of my colleagues. The input to the Triennial Review from the Institute of Physics, for example, is basically that nothing should change. However, I think that’s largely because most of us working in STFC area,  have much greater confidence in the current management than we did in the previous regime rather than because the structure is right. Some of the bureaucrats in the Treasury, RCUK and HEFCE won’t like my suggestion  either, because they’ll all have to go and do something more useful.  But unless someone stands up for the university sector and does something to safeguard future funding then the ongoing decline in funding levels will never be reversed.

I very much doubt if many of my fellow physicists or astronomers agree with my suggestion either. Not to worry. I’m used to being in a minority of one. However, even if this is the case I hope this somewhat lengthy post will at least get you thinking. As always, I’d be interested in comments..

Dirac Lectures

Posted in The Universe and Stuff with tags , , on April 11, 2013 by telescoper

Earlier this year I posted a review of a book about the great theoretical physicist Paul Dirac. Presumably by a complete coincidence, on the very same day that I wrote that piece, somebody put the following video on Youtube. It’s very rare footage of the man himself giving some lectures in Christchurch, New Zealand in 1975 (when he was in his 70s). A great deal of conflicting stuff has been written about what Dirac was like as a lecturer – now you can see for yourself. The video isn’t very high quality – it breaks up entirely in a few places – but it’s nevertheless fascinating to hear Dirac talk physics!

My opinion? I’ve had worse!

p.s thanks to Ian Harrison (@itrharrison) for drawing this to my attention!

Sometimes it happens…

Posted in Poetry with tags , , on April 10, 2013 by telescoper

And sometimes it happens that you are friends and then
You are not friends,
And friendship has passed.
And whole days are lost and among them
A fountain empties itself.

And sometimes it happens that you are loved and then
You are not loved,
And love is past.
And whole days are lost and among them
A fountain empties itself into the grass.

And sometimes you want to speak to her and then
You do not want to speak,
Then the opportunity has passed.
Your dreams flare up, they suddenly vanish.

And also it happens that there is nowhere to go and then
There is somewhere to go,
Then you have bypassed.
And the years flare up and are gone,
Quicker than a minute.

So you have nothing.
You wonder if these things matter and then
As soon you begin to wonder if these things matter
They cease to matter,
And caring is past.
And a fountain empties itself into the grass.

Open Access Update

Posted in Open Access with tags , , , on April 9, 2013 by telescoper

Very busy today with meetings. It’s a pleasant job introducing myself to all the new staff we’ve been appointing, but it does take quite a bit of time!

Anyway, I’ve just got a few moments  for a quick post while I eat a sandwich – sorry for the crumbs – in order to pass on some news about Open Access. The main thing is that, after a brief consultation last month, RCUK has (yet again) revised its policy on Open Acsess. The new guidance can be found here and there’s a Frequently Asked Questions (FAQ) supplement here. There’s even an explanatory blog post here.

Here’s an excerpt from the latter:

One of the most high profile additions to the guidance that we were asked for was, through Stephen Curry’s blog and subsequent letter, clarification that journal impact factors are not taken in to account when the Research Councils make funding decisions.

It’s good to see a science blogger making a real difference to policy! One can only dream.  Incidentally, I did post a little commentary on his post on here too and I’m very glad to see this clarified. Impact Factors are, frankly, bollocks. Perhaps that’s why so many publishers are obsessed with them?

I won’t copy the whole policy document here, but it is perhaps worth including the “Key Points to Note”:

  • This policy applies only to the publication of peer‐reviewed research articles (including review articles not commissioned by publishers) and conference proceeding sthat acknowledge funding from the UK’ s Research Councils.
  •  The Research CouncilsUK (RCUK) policy supports both ‘Gold’ and ‘Green’ routes to Open Access, though RCUK has a preference forimmediateOpen Access with the maximum opportunity for re‐use;
  •  Funding for Open Access arising from Research Council‐supported research will be available through a block grant awarded directly to research organisations;
  •  RCUK recognises that the journey to full Open Access is a process and not a single event and therefore it expects compliance to grow over a transition period anticipated to be five years; RCUK will undertake a comprehensive, evidence‐based review of the effectiveness and impact of its Open Access policy in 2014 and periodically thereafter(probably in 2016 and 2018);
  • When assessing proposals for research funding RCUK considers that it is the quality of the research proposed, and not where an author has or is intending to publish, that is of paramount importance;
  • RCUK is mindful that the impact ofits policy on different disciplinary areas is likely to be varied and has therefore made allowance for a different pace of adjustment by permitting different embargo periods across the discipline supported by the Research Councils. We will also be mindful of these differences between disciplines when monitoring the impact of the policy and, in future processes, when looking at compliance.

This is all very much more encouraging than the original guidance, but it remains to be seen whether it will evolve further.

P.S. A new Open-Access-O-Meter is available here. Just type in the Research Council funding your research, the journal you wish to publish in, and hey presto!

A Small Problemette related to Cosmological non-Gaussianity

Posted in Cute Problems, The Universe and Stuff with tags , , , on April 8, 2013 by telescoper

Writing yesterday’s post I remembered doing a calculation a while ago which I filed away and never used again. Now that it has come back to my mind I thought I’d try it out on my readers (Sid and Doris Bonkers). I think the answer might be quite well known, as it is in a closed form, but it might be worth a shot if you’re bored.

The variable x has a normal distribution with zero mean and variance \sigma^{2}. Consider the variable

y = x + \alpha \left( x^2 - \sigma^2 \right),

where \alpha is a constant. What is the probability density of y?

Answers on a postcard through the comments box please..

Has Planck closed the window on the Early Universe?

Posted in The Universe and Stuff with tags , , , , , , , , on April 7, 2013 by telescoper

A combination of circumstances – including being a bit poorly – has made me rather late in getting around to reading the papers released by the Planck consortium a couple of weeks ago. I’ve had a bit of time this Sunday so I decided to have a look. Naturally I went straight for, er, paper No. 24, which you can find on the arXiv, here.

I picked this one to start with because it’s about primordial non-Gaussianity. This is an important topic because the simplest theories of cosmological inflation predict the generation of small-amplitude irregularities in the early Universe that form a statistically homogeneous and isotropic Gaussian random field. This means that the perturbations (usually defined in terms of departures of the metric from a pure Robertson-Walker form) are defined by probability distributions which are invariant under translations and rotations in 3D space.

In a nutshell, such perturbations arise quite simply in inflationary cosmology as zero-point oscillations of a scalar quantum field, in a very similar way the Gaussian distributions that arise from the quantized harmonic oscillator. Assuming the fluctuations are small in amplitude the scalar field evolves according to

\ddot{\Phi} +3H\dot{\Phi} + V^{\prime}(\Phi),

which is similar to that describing a ball rolling down a potential V, under the action of a force given by the derivative V^{\prime}, opposed by a “frictional” force depending on the ball’s speed; in the inflationary context the frictional force depends on the expansion rate H(\Phi, \dot{\Phi}). If the slope of the potential is relatively shallow then there is a slow-rolling regime during which the kinetic energy of the field is negligible compared to its potential energy; the term in \ddot{\phi} then becomes negligible in the above equation. The universe then enters a near-exponential phase of expansion, during which the small Gaussian quantum fluctuations in \Phi become Gaussian classical metric perturbations.

On the one hand, Gaussian fluctuations are great for a theorist because so many of their statistical properties can be calculated analytically: I played around a lot with them in my PhD thesis many moons ago, long before Planck, in fact long before any fluctuations in the cosmic microwave background were measured at all! The problem is that if we keep finding that everything is consistent with the Gaussian hypothesis then we have problems.

The point about this slow-rolling regime is that it is an attractor solution that resembles the physical description of a body falling through the air: eventually such a body reaches a terminal velocity defined by the balance between gravity and air resistance, but independent of how high and how fast it started. The problem is that if you want to know where a body moving at terminal velocity started falling from, you’re stumped (unless you have other evidence). All dynamical memory of the initial conditions is lost when you reach the attractor solution. The problem for early Universe cosmologists is similar. If everything we measure is consistent with having been generated during a simple slow-rolling inflationary regime, then there is no way of recovering any information about what happened beforehand because nothing we can observe remembers it. The early Universe will remain a closed book forever.

So what does all this have to do with Planck? Well, one of the most important things that the Planck collaboration has been looking for is evidence of non-Gaussianity that could be indicative of primordial physics more complicated than that included in the simplest inflationary models (e.g.  multiple scalar fields, more complicated dynamics, etc).  Departures from the standard model might just keep the window on the early Universe open.

A simple way of defining a parameter that describes the level of non-Gaussianity is as follows:

\phi = \phi_{G} + f_{NL} \left( \phi_{G}^2 -< \phi_{G}^2 > \right)

the parameter f_{NL} describes a quadratic contribution to the overall metric perturbation \phi: you can think of this as being like a power series expansion of the total fluctuation in terms of a Gaussian component \phi_{G}; the term in angle brackets is just there to ensure the whole thing averages to zero. This definition of non-Gaussianity is not the only one possible, but it’s the simplest and it’s the one for which Planck has produced the most dramatic result:

f_{NL}=2.7 \pm 5.8,

which is clearly consistent with zero. If this doesn’t look impressive, bear in mind that the typical fluctuation in the metric inferred from cosmological measurements is of order 10^{-5}. The quadratic terms are therefore of order 10^{-10}, so the upper limit on the level of non-Gaussianity allowed by Planck really is minuscule. This is one of the reasons why some people have described the best-fitting model emerging from Planck as the Maximally Boring Universe

So it looks like only very unwise investors will be buying shares in cosmological non-Gaussianity at least in the short-term. More fundamentally we may be approaching the limit of what we can learn about inflation in particular, or even the early Universe in general, using the traditional techniques of observational cosmology. But there remain very intriguing questions that may yet shed light on the pre-inflationary epoch. Among these are the large-scale anomalies seen in the very same Planck data that have put such stringent limits on non-Gaussianity. But that question, described in Planck Paper 23, will have to wait for another day…

The Meeting Place

Posted in Biographical with tags , on April 6, 2013 by telescoper

Spring seems to be arriving in Brighton at last, so I decided to take a stroll along the seafront. There were substantial crowds out and about who obviously had the same idea. Nice to see the place coming to life as the weather improves.

This little cafe is just on the Hove side of town. I used to be a regular here about 25 years ago, and it hasn’t changed much at all since then.

I can’t visit this spot without rekindling a very sad memory of that time. I was just sitting having a coffee on a Sunday morning when an odd-looking, rather gangly man approached the cafe. He was about 50 years old, wearing a suit and tie, and carrying a newspaper under his arm. As he got closer, however, I saw that he wasn’t just slightly eccentric; he had an expression of pure terror on his face.

The man went up to the counter and after some time managed to order tea and a scone, although by then he was visibly trembling. He sat down. Before he could do any more, however, his nerves got the better of him and he was sick over his table, and a bit on his clothes. He began to cry and left the cafe as quickly as he could, crestfallen. He left his newspaper behind.

I had no idea what torments that poor soul endured that morning, although I probably understand a bit better after recent experiences. I guess that he was trying to conquer a fear of crowds, was unused to everyday situations for some reason, or had some other anxiety-related problem. Sadly he lost that particular battle. I never saw him again at The Meeting Place, and have no idea what became of him.

I should add that neither I nor anyone else at the Meeting Place lifted a finger to help him. If he ever did managed to find some way of handling his problem, it was certainly no thanks to me. Shame lasts a lifetime.
