The end draws near – the PhD viva

Submitted PhD thesis

Submitted PhD thesis

A few months ago, I submitted my PhD thesis. After all of the preparation and writing, submitting was somewhat of an anti-climax. This is because submitting those nicely bound volumes means nothing unless someone is going to read and examine them to determine if the work they contain will earn you the degree and the right to call yourself Dr.

In the UK, these examinations often happen some time after submitting, in a process known as the viva. These exams involve the examiners coming to the university/institute and conducting a private, face-to-face examination of your knowledge and the work presented in the thesis, often over a number of hours.

All this is purely explanation of the main point:

I had my PhD viva on Monday and I passed!

I passed with the most common outcome; minor corrections. This means that whilst I have passed, the examiners would like some changes to be made before the final version of record is submitted. It is only when they are happy with those changes that I will officially earn the degree.

For now, I’m beginning to come down from the celebrations and start working towards the corrections. So it is still not yet the end; I think the real closure will happen when the award letter and certificates are in my hands.

Is using an academic title automatically an ‘argument from authority’?

We are bombarded with ‘expert opinions’ every day in the media, both printed and broadcast, and many of these people are presented to us with their title: Prof, Dr, PhD, FRS and the like. An example might be this recent story on sleep deprivation and stroke from the Guardian, which is followed throughout.

My questions are: does including their “rank” in the scientific hierarchy automatically say to the audience “you should believe this person for they are more qualified than you“, is this committing an ‘argument from authority‘ and does this even matter at all?

The first question translates basically to whether or not an academic’s title is optional. On the one hand, they’ve earned the degree/accolade by working pretty damn hard and deserve to be called by it. In 3 years time, when (hopefully) I finish my PhD, I’ll be pretty cheesed off if ‘Dr’ doesn’t get written down in the right places. On the other hand, within science (certainly biology/biochemistry), people don’t much use their titles. At the institute where I work, titles are basically relegated to the telephone directory and a handful of email signatures. They certainly don’t appear on published papers, so why in the press release and press coverage. (As an aside, this is different in the medical world such as the BMJ, The Lancet and NEJM, where author qualifications are published). If they aren’t on the paper itself, I think that says to me that they aren’t needed in the press coverage, but I’ll admit that it’s an open question.

Does the inclusion of these titles confer authority on to whatever quote their holder is giving? I think they probably do. This might not be the intention in science reporting but it has that effect. Why else would people be so keen to use the title Dr, if not to be accepted as an expert in a field?

A better question is whether worrying about presenting a well-qualified expert as an authority figure actually matters? As noble as the Royal Society’s motto might be (nullius in verba – On the word of no-one), equally nobody has time to fact check everything, and qualifications and titles are often a pretty good heuristic for reliability. As Paul Nurse (or perhaps “the Nobel laureate Sir Paul Nurse PRS) recently put to James Delingpole (3m30s), when you go to a doctor, you trust their clinical judgment. You might do your own research and disagree with the consensual position, but that would be a very unusual position to take.

The problem – as there is with all such rules of thumb – is that it is open for exploitation. I alluded earlier to those who ‘pass off’ having more qualifications than they have, often in order to lend their opinion legitimacy, often for monetary gain in the form an endorsement by an expert. Weirdly, this means that every time a title such as Dr is used legitimately, it adds weight to all those using the same title illegitimately. A reverse problem can also occur – someone with a legitimate qualification, in a relevant field presents a maverick view rather than scientific consensus and can be spectacularly wrong, but still taken “on authority”. Think Andrew Wakefield and the disproven MMR/Autism link for an example.

On balance, I’m not sure that there is a right answer to the use of academic titles. To me they are a mark of respect and achievement, not authority and certainly don’t mean that everything the holder says is true and sacrosanct, but I’m not sure that is always how they are taken.

Science is Vital

Supporters at the rally

Supporters at the rally

Yesterday, I attended (and helped marshall, as evidenced here) the rally for an important campaign called Science is Vital. It is a campaign against any proposed cuts to the science budget, when the spending review is published later in the month. I urge anybody who hasn’t already done so to: check out their website which details all the reasons why continued investment in science is a necessity, sign their petition and write to their MP about the campaign. It was a fantastic afternoon and great to meet up with so many people that I’ve heard about or briefly tweeted @ them but never spoken; even if it was under unfortunate circumstances with the prospect of cuts hanging over all our heads.

This campaign is more than just a self-interested group getting antsy about a policy they don’t like. Yes, many of the people who have signed the petition are scientists who are understandably worried about their own careers. I am also worried about what the state of biomedical science will be when I start looking for my first position after finishing my PhD in 3 years time.

This is about more than that though. We are saying

We already don’t have enough money to do all the research we need, with only around 20% of grant proposals finding funding, and yet we greatly ‘punch above our weight’, in almost any metric you pick; number of World-class universities, citations per researcher, papers produced against spend. We can’t get more efficient. We are already at the limit.

And it isn’t the scientists that will be the biggest losers in this. They can move to other world-leading institutions in the US, Japan, India, Australia, Germany and others. It is society that loses out, as we have to become reliant on the work of other countries to fulfil our scientific, technological and engineering needs.

The Campaign for Science and Engineering has plenty more on the economic reasons why science funding is a poor judgment, so if you like facts and figures, head here. The Science is Vital campaign has also collated photos and other reports from the event and the Pod Delusion has podcasts of all the speakers and some reporting from the rally. The rest of my own photos from the event can be found in this Flickr set.

Night at the museum

Once a month, on the last Wednesday, the Science Museum opens its doors at night for adults only until about 10pm. Not only are the general exhibits open, but there are also special events and a recurring silent disco (in between the space exhibits!) and a pub quiz. Another notable additions include a number of bars and DJs being set up in exhibition spaces which adds to the relaxed atmosphere. Each month also has a theme and last night’s was “Genius”.

This was my second Science Museum Lates and the first one I’ve brought my camera along to, so here are a few photos documenting what we got up to last night:

Adult table football (Sadly I don't have any pictures of us)

Firstly we played this somewhat hilarious game of 5-a-side “table football” where we were all attached to sliders along scaffolding tubes for 5 minutes. Not entirely sure how this relates to genius; I guess through the tenuous link of “footballing genius” to remind us that a genius doesn’t have to be about academic intellect, but it was fun none the less. We lost 6-2!

Fun with the bubblewall

More bubble wall fun

Then it was off to play like children in the LaunchPad, as you can see we were particularly fascinated by the bubble wall thing! Before going to see a demonstration of Newton’s laws, as they related to rockets!

Newton's 3rd law in action via a human rocket.

Culminating in a hydrogen balloon explosion. 😀

After all that LaunchPad fun it was off to test our brains in a massive genius-themed pub quiz (complete with colouring competition!). We didn’t win either I’m sad to report – despite a valiant colouring attempt mounted by 2 of our teammates followed by a brief look around the plastics and the Islam exhibition rooms.

A few more of my photos are in this Flickr set and photos from myself and other participants across the other Lates nights are all in the Flickr group ‘Science Museum Lates’.

My only complaint (if you can call it that…) is that with so much going on, there is so little time to look at the exhibits! Maybe it should be another hour longer! Otherwise this is a great idea and definitely gets people into the museum who wouldn’t otherwise have gone, hopefully teaching a bit of informal science too and being a great fun night out.

The next one is 30th June – theme TBC I think. See you there!

The Green Party Manifesto

Yesterday, the Green Party manifesto was launched. Last year I remarked (in passing and via a Times article) that the Green Party are not that hot on science/research in their manifesto for the European elections. This year in their general election video, the story is not that different, with some of the same pledges coming out to play. I have already blogged on the main parties manifesto commitments to science and education, but coming later than the other parties, and being sufficiently, well, interesting, I’ll dedicate a whole post to their pledges.

Firstly, I should mention that the word “science” doesn’t appear at all in the manifesto. However, they do have some pretty far reaching science pledges, such as this one. (emphasis throughout is all theirs.)

Immediately ban causing harm to animals (including but not only primates) in research, testing and education, and invest in the development of alternatives to animal experiments.

I’m not entirely sure I have the words to describe what I think of this pledge. Use of animals in research is clearly necessary for progress in medical research (as are humans and human tissue), despite being a fairly terrible reality. I think the BBC sums up the arguments in both directions quite well, particularly the quote from William DH Carey in a letter to the BMJ. This pledge would halt some aspects of medical research; killing people and disadvantaging us as a nation. To me this alone means I could not vote for a Green candidate. Strong regulation is one thing, but an outright ban is preposterous.

Next an onslaught again genetic modification (GM).

work for a complete ban on genetically modified food in Europe.

Here we have a technology that could help end some of the more dubious farming methods that their manifesto also discusses at length, and yet the Green Party are against it. The mind boggles.

Finally, they have this beauty on CAM.

Make available on the NHS complementary medicines that are cost-effective and have been shown to work.

Another “words fail me” moment. Cost-effective and proven to work, yes. We call that evidence-based medicine, though, not complementary. I think Tim Minchin says this best in Storm:

You know what they call “alternative medicine”
That’s been proved to work?
Medicine.”

In the interest of balance, I tried to find some science policies that I thought were positive, but alas there were none. Education is at least slightly better.

Move towards ending the need for private education by creating a programme of voluntary assimilation of private schools into the state sector. Schools that remain in the private sector would have charitable status removed and would pay all relevant taxes, such as VAT.

Finally, something I agree on. I feel strongly that education should be provided on a merit-based system, so that the brightest, not the wealthiest, get the best education. It is both best for the best individuals to be well-educated and for society who will eventually reap their benefit from the output of our brightest. Making it hard for private schools to operate is a step in the right direction.

Now don’t get me wrong, there are plenty of great things in the Green Party manifesto to be excited about such as pledges on:

  • ban sale of eggs from battery hens
  • maintain and extend blood sports ban
  • increase spend on waste management and recycling

and other both predictable and laudable pledges that you would expect from the Green Party. Sadly just not in the areas that are strongest to me.

Overall: Pitiful on science, a party I could not vote for.

Science in the Manifestos

So following my earlier blog post on where the parties stood on libel reform, I thought I’d continue by examining another subject that I feel strongly about: science and science education. Now that the 3 main parties have published their manifestos, let’s see where they stand.

Labour

Labour were first out of the traps to release their manifesto, so it is only fair they get to go first.

[They] are committed to a ring-fenced science budget in the next spending review

This is great news, although an improvement and increase would be better. As Prof. Brian Cox has said (over and over), investing in science creates wealth, so an increase would actually help the economy in the long-term, and to cut it would make such a small saving in the short-term compared to long-term losses as to be non-sensical.

To help us do better in turning research outputs into innovation, we will provide focused investment for Technology and Innovation Centres, developing technologies where the UK has world-leading expertise

Not sure about this one; sounds very good, but we already have enough “focus” on impact statements for researchers and trying to second-guess how useful the research will be. The problem is, sometimes you can’t know what the eventual outcome of the research will be until you do it. The oft-quoted example is Sir Tim Berners-Lee and the World Wide Web that came out of CERN with an outcome beyond that originally expected.

We will also support university research through the Higher Education Innovation Fund…

Not entirely sure what they are getting at there. This isn’t a new body, the HEIF already exists to the tune of £150m this coming academic year. I presume they just mean they will continue what they have already announced. Not much of a pledge.

More young people will be able to study single science subjects

We reject a return to the 11-plus or free-for-all admission system

…raising the education leaving age to 18.

Single sciences are definitely the way forward to inspire young people to continue in science. Enjoyment of any subject comes from having a good understanding of it, and this is particularly true in the sciences, and I think this can best be taught separately. And whilst the sciences do all converge, it is also important to recognise that there is no such thing as “science” as a single entity and that the subjects can be quite different and so it is perfectly possible to enjoy different facets of science without much reference to the others.

Continuing to be against the 11-plus is no great surprise, although as a someone very much in favour of Grammar schools (and educated at one), it does disappoint me.

As for raising the leaving age, I can’t say I’m thrilled at that. Diversification of education and apprenticeships might lessen the blow somewhat, but I still remember being at school with those who distinctly didn’t want to be so left when they could. Not sure I could have taken it for another 2 years!

Overall: Nice, but vague.
Full Manifesto

Conservatives

Second out to be published and my party of choice, but what do they have to say?

a multi-year Science and Research Budget to provide a stable investment climate for Research Councils

delay the implementation of the Research Excellence Framework so that it can be reviewed – because of doubts about whether there is a robust and acceptable way of measuring the impact of all research

Multi-year is good, long term would be better for Research Council stability. Where is the increase? Or at least ring fence as Labour have promised. I am disappointed that there is not a more concrete promise in there.

The explicit recognition of the problems encountered when measuring research impact is excellent. It is a minefield and so the implication that the Conservatives want to find a “robust and acceptable” measure is exciting indeed. This also pleases my sense that manifestos should contain specific detail!

creating a better focus on Science, Technology, Engineering and Maths (STEM) subjects in schools

Another admirable ambition, but I feel that it is almost pointlessly vague.

allow all state schools the freedom to offer the same high quality international exams that private schools offer – including giving every pupil the chance to study separate sciences at GCSE

As someone who attended a state school that taught the International Baccalaureate Diploma, studied separate science from the age of 11 and has gone on to 2 science degrees (soon to be 3), I am living proof that a detailed science education can be inspiring and empowers those who want to learn. Therefore, I can’t sing highly enough the praises of this pledge.

Overall: wishy-washy, especially given the length of the document, more detail would have been nice.
Full Manifesto

Liberal Democrat

Last out of the blocks this morning, and one that I have been eagerly awaiting having seen Dr Evan Harris talk before about the Lib Dem commitment to science. I have to say, I was not disappointed:

Respect the convention that the science budget, once allocated through the Comprehensive Spending Review process, is not used for other purposes

Not as strong a way of pledging to protect the science budget, but I suppose “every little helps”. Still no ring-fence and certainly not a pledge to increase it though. Sad, but probably honest at least.

Ensure that the decisions on the funding of research projects are made on the basis of peer review not Whitehall interference, while recognising the need for government to identify broad strategic priorities in a transparent manner.

Reform science funding to ensure that genuinely innovative scientific research is identified and supported, instead of basing funding decisions on narrow impact factors.

These two pledges are similar to the Tory pledge on funding and the Research Excellence Framework, and are welcome. Along with the introduction to the science section of the manifesto, I think the way these pledges are worded is proof that the Lib Dems get science. To me they just seem to hit the mark better than the similar Tory pledge. I wonder if it is more of Dr Evan Harris’ work.

Ensure that all state-funded research, including clinical trials, is publicly accessible and that the results are published and subject to peer review

A pledge for open-access publishing! I really didn’t see that coming as it isn’t exactly of mainstream interest and I wonder how the higher cost of open-access publishing would be covered with the inevitable increased grant funding it would required. To me, just the recognition of the issue is brilliant though, and something the Lib Dems should be commended for.

Safeguard academic freedom and the independence of scientific advisers by amending the Ministerial Code to prevent government from bullying or mistreating advisers and distorting evidence or statistics

They also sneaked in this pledge regarding evidence-based policy into their science section, which again, I’m sure will go down well with the science community.

Give 14–19 year-olds the right to take up a course at college, rather than at school, if it suits them better. This will enable all children to choose to study, for example, separate sciences or modern languages at GCSE, or a vocational subject.

This completes the set of parties wishing to bring back single science education at GCSE level. It is worrying that they don’t think it should be taught within the school but offered as an option elsewhere, in contrast to what Tories appear to pledged though.

Overall: With more detail and specific science pledges, it seems like the Lib Dems understand the science vote.

Summary

In many ways, it is hard to differentiate between the parties based on their science pledges, with them all wishing a return to separate sciences and to review the way in which science grants are allocated, so it is very hard to definitively choose based on science policy alone. To me the Lib Dems have the upper hand at the moment, both because they have some superior content and pledges, but also because the way it is written and the specifics it goes into just seem to show a better understanding and honesty over the current science issues, but I think that is purely a personal feeling.

In fact, I think that applies all the way through the Lib Dem manifesto from my skim read of it so far, and it is almost making me turn from committed Tory voter – especially if I want to stand a chance of outing Frank Dobson in my area – but that is another story entirely.
