Stern Response

Posted in Science Politics with tags , , on July 28, 2016 by telescoper

The results of the Stern Review of the process for assessing university research and allocating public funding has been published today. This is intended to inform the way the next Research Excellence Framework (REF) will be run, probably in 2020, so it’s important for all researchers in UK universities.

Here are the main recommendations, together with brief comments from me (in italics):

  1. All research active staff should be returned in the REF. Good in principle, but what is to stop institutions moving large numbers of staff onto teaching-only contracts (which is what happened in New Zealand when such a move was made)?
  2. Outputs should be submitted at Unit of Assessment level with a set average number per FTE but with flexibility for some faculty members to submit more and others less than the average.Outputs are countable and therefore “fewer” rather than “less”. Other than that, having some flexibility seems fair to me as long as it’s not easy to game the system. Looking it more detail at the report it suggests that some could submit up to six and others potentially none, with an average of perhaps two across the UoA. I’m not sure precise  numbers make sense, but the idea seems reasonable.
  3. Outputs should not be portable. Presumably this doesn’t mean that only huge books can be submitted, but that outputs do not transfer when staff transfer. I don’t think this is workable, but that what should happen is that credit for research should be shared between institutions when a researcher moves from one to another.
  4. Panels should continue to assess on the basis of peer review. However, metrics should be provided to support panel members in their assessment, and panels should be transparent about their use. Good. Metrics only tell part of the story.
  5. Institutions should be given more flexibility to showcase their interdisciplinary and collaborative impacts by submitting ‘institutional’ level impact case studies, part of a new institutional level assessment. It’s a good idea to promote interdisciplinarity, but it’s not easy to make it happen…
  6. Impact should be based on research of demonstrable quality. However, case studies could be linked to a research activity and a body of work as well as to a broad range of research outputs. This would be a good move. The existing rules for Impact seem unnecessarily muddled.
  7. Guidance on the REF should make it clear that impact case studies should not be narrowly interpreted, need not solely focus on socio-economic impacts but should also include impact on government policy, on public engagement and understanding, on cultural life, on academic impacts outside the field, and impacts on teaching. Also good.
  8. A new, institutional level Environment assessment should include an account of the institution’s future research environment strategy, a statement of how it supports high quality research and research-related activities, including its support for interdisciplinary and cross-institutional initiatives and impact. It should form part of the institutional assessment and should be assessed by a specialist, cross-disciplinary panel. Seems like a reasonable idea, but a “specialisr cross-disciplinary” panel might be hard to assemble…
  9. That individual Unit of Assessment environment statements are condensed, made complementary to the institutional level environment statement and include those key metrics on research intensity specific to the Unit of Assessment. Seems like a reasonable idea.
  10. Where possible, REF data and metrics should be open, standardised and combinable with other research funders’ data collection processes in order to streamline data collection requirements and reduce the cost of compiling and submitting information. Reasonable, but a bit vague.
  11. That Government, and UKRI, could make more strategic and imaginative use of REF, to better understand the health of the UK research base, our research resources and areas of high potential for future development, and to build the case for strong investment in research in the UK. This sounds like it means more political interference in the allocation of research funding…
  12. Government should ensure that there is no increased administrative burden to Higher Education Institutions from interactions between the TEF and REF, and that they together strengthen the vital relationship between teaching and research in HEIs. I believe that when I see it.

The Rising Stars of Sussex Physics

Posted in Bad Statistics, Biographical, Education with tags , , , , on July 28, 2016 by telescoper

This is my penultimate day in the office in the School of Mathematical and Physical Sciences at the University of Sussex, and a bit of news has arrived that seems a nice way to round off my stint as Head of School.

It seems that Physics & Astronomy research at the University of Sussex has been ranked as 13th in western Europe and 7th in the UK by leading academic publishers, Nature Research, and has been profiled as one of its top-25 “rising stars” worldwide.

I was tempted to describe this rise as ‘meteoric’ but in my experience meteors generally fall down rather than rise up.

Anyway, as regular readers of this blog will know, I’m generally very sceptical of the value of league tables and there’s no reason to treat this one as qualitatively any different. Here is an explanation of the (rather curious) methodology from the University of Sussex news item:

The Nature Index 2016 Rising Stars supplement identifies the countries and institutions showing the most significant growth in high-quality research publications, using the Nature Index, which tracks the research of more than 8,000 global institutions – described as “players to watch”.

The top 100 most improved institutions in the index between 2012 and 2015 are ranked by the increase in their contribution to 68 high-quality journals. From this top 100, the supplement profiles 25 rising stars – one of which is Sussex – that are already making their mark, and have the potential to shine in coming decades.

The institutions and countries examined have increased their contribution to a selection of top natural science journals — a metric known as weighted fractional count (WFC) — from 2012 to 2015.

Mainly thanks to a quadrupling of its physical sciences score, Sussex reached 351 in the Global 500 in 2015. That represents an 83.9% rise in its contribution to index papers since 2012 — the biggest jump of any UK research organisation in the top 100 most improved institutions.

It’s certainly a strange choice of metric, as it only involves publications in “high quality” journals, presumably selected by Journal Impact Factor or some other arbitrary statistical abominatio,  then taking the difference in this measure between 2012 and 2015  and expressing the change as a percentage. I noticed one institution in the list has improved by over 4600%, which makes Sussex’s change of 83.9% seem rather insignificant…

But at least this table provides some sort of evidence that the investment made in Physics & Astronomy over the last few years has made a significant (and positive) difference. The number of research faculty in Physics & Astronomy has increased by more than 60%  since 2012 so one would have been surprised not to have seen an increase in publication output over the same period. On the other hand, it seems likely that many of the high-impact papers published since 2012 were written by researchers who arrived well before then because Physics research is often a slow burner. The full impact of the most recent investments has probably not yet been felt. I’m therefore confident that Physics at Sussex has a very exciting future in store as its rising stars look set to rise still further! It’s nice to be going out on a high note!
