The gig economy

Joe plays guitar in a metal band – averagely well for a 20-year-old – and is enrolled on a music degree course at a post-92 university whose most pressing issue is its own surviva. He didn’t have to audition and there was no real interview. He was told what to expect, but he didn’t fully internalise the message that he’d be better off if he could read music.

The problem is that the delivery and even the content of the courses these days are centrally informed by student feedback, which goes straight to middle management. If some students say that there’s too much classical music, modules get chopped. Coursework is dumbed down. New modules are frowned on (students walk away from the unfamiliar). Feedback is narrowly prescribed, and entered on to tick sheets. The spectre of student complaint lurks at every corner.

This wholesale embrace of populism in pursuit of higher recruitment and satisfaction numbers irons out musical minorities and marginalises any sense that music is a value in and for itself. Gone is the idea that study can (and should) be difficult at times, and certainly not always concerned with what is most immediate. Gone is the possibility of a musical democracy based on a critically informed public.

This article is about Music Degrees, but many in Higher Education will recognise the tune.

Crash landing

Europeans may wish to opt out of the global battle for corporate domination. They may even hope that they may thus achieve a greater degree of freedom for democratic politics. But the risk is that their growing reliance on other people’s technology, the relative stagnation of the eurozone and the consequent dependence of Europe’s growth model on exports to other people’s markets will render those pretensions to autonomy quite empty. Rather than an autonomous actor, Europe risks becoming the object of other people’s capitalist corporatism. Indeed, as far as international finance is concerned, the die has already been cast. In the wake of the double crisis, Europe is out of the race. The future will be decided between the survivors of the crisis in the United States and the newcomers of Asia.44 They may choose to locate in the City of London, but after Brexit even that cannot be taken for granted. Wall Street, Hong Kong and Shanghai may simply bypass Europe.

From: ‘Crashed: How a Decade of Financial Crises Changed the World’ by Adam Tooze. This book brings to my mind Alan Kay’s comment when he was awarded the Turing Prize:’the computer revolutions hadn’t happened yet’. I don’t think we have even begun to live through the worst of the Crash (yet).

None of the proposals were awarded.

This is from David Hubel, although the citation is not to hand.

Most importantly, today’s organization of science tends to deprive a young scientist of one of the most important learning experiences, that of thinking up a project of one’s own and carrying it through; deciding for oneself, independently, whether to persist or to give up and switch over to something else.

What’s the point of scholarly academies? | Times Higher Education (THE)

Academies can also argue for different research priorities from universities, he pointed out. As if by “magic”, when universities create their own research strategies, “they all focus on medical sciences and life sciences”, he said. But their motivation is often financial, as they want to host subjects with strong economic links, he said.

On the contrary, academies are better placed to make the case for the less lucrative humanities and social sciences, he argued, and do not need to generate corporate research funding, meaning that they can be more objective about what type of research is needed to help society. One of the key roles of academies is “thinking about the societal consequences of new knowledge”, Professor Loprieno added.

Schrödinger’s cat among biology’s pigeons: 75 years of What Is Life?

What is Life? helped to make influential biologists out of several physicists: Crick, Seymour Benzer and Maurice Wilkins, among others. But there’s no indication from contemporary reviews that many biologists grasped the real significance of Schrödinger’s code-script as a kind of active program for the organism. Some in the emerging science of molecular biology were critical. Linus Pauling and Max Perutz were both damning about the book in 1987, on the centenary of Schrödinger’s birth. Pauling considered negative entropy a “negative contribution” to biology, and castigated Schrödinger for a “vague and superficial” treatment of life’s thermodynamics. Perutz grumbled that “what was true in his book was not original, and most of what was original was known not to be true even when the book was written”.

USS crisis: can the pension system be reformed? | Times Higher Education (THE)

As such, the 2004 Pensions Act is a prime, but by no means unique, example of well-intentioned but inept financial regulation. Over-prescriptive, it has led to the demise of the defined benefit schemes that it was designed to protect. If proposed changes to the USS are implemented, there will be no defined benefit schemes of any significant size outside the public sector open to new members.

Pseudoaddiction.

If a doctor expressed concern about a patient showing signs of addiction, Ms Panara was trained to counter those fears by educating them on so-called pseudo-addiction, she says. For example, an addict might turn up at the surgery requesting a fresh batch of pills before their 30-day supply should have run out, claiming they had lost the tablets or accidentally dropped them down the toilet. The advice that she was told to give the doctor was that the patient’s dosing was too low and should be increased, she says.

“The theory of pseudo-addiction was that a patient might exhibit these drug-seeking behaviours, but if their pain were adequately managed by giving a higher dose, then that drug-seeking behaviour would cease,” she says. “Thereby we were building their tolerance, building their physical dependence, and making them an addict.”

I still fail to see why we need drug representatives, nor why they are allowed.

Universities: the year ahead

We need to demonstrate much more clearly that Universities (and their leaders) are listening and acting. Much of the criticism levelled at HE is legitimate so the sector needs to take action to transform both itself and in turn the opinion of some of the public. This can be achieved through greater transparency relating to fees, funding and value; an even more proactive approach to the big issues (diversity, mental health, social mobility, relationships with business) and a collective and authentic approach to sharing all that is great in UK HE.

For a baseline life expectancy of 80 years:

  • Eating 12 hazelnuts daily (1 oz) would prolong life by 12 years (ie, 1 year per hazelnut)
  • Drinking 3 cups of coffee daily would achieve a similar gain of 12 extra years
  • Eating a single mandarin orange daily (80 g) would add 5 years of life.

Conversely:

  • consuming 1 egg daily would reduce life expectancy by 6 years
  • eating 2 slices of bacon (30 g) daily would shorten life by a decade (an effect worse than smoking).

Well these are all taken from John Ioannadis’ article in JAMA. He asks : “Could these results possibly be true?”

The great financial crash led to some (but not enough) soul-searching about the state of academic economics and, in turn, the academy. Whole swathes of the modern research university are geared to the production of unreliable knowledge.  There is money in it. Without wishing to understate in any way Ioannadis’ major contributions, we have known that there are fundamental methodological flaws in much of observational epidemiology for a long time (for instance see the late Alvan Feinstein’s article in Science). A must read.

“The song remains the same”

From an obituary of Paul Boyer.

“Paul Boyer was approaching the finish line of his career when he risked everything with a jaw-dropping proposal. He addressed one of the most important, as-then-unanswered questions in biochemistry”

“We were attending a UCLA seminar in 1972 when I noticed that he wasn’t paying attention to the speaker. Afterwards, Paul approached us in a very excited state. This was surprising because he was known for his calm demeanour. He confessed that he had spent the hour thinking about old unexplained data. He asked: “What would you say if I told you that it doesn’t take energy to make ATP at the catalytic site of ATP synthase,” (as was universally held at the time) “but rather that it takes energy to get ATP off the catalytic site?” This was a eureka moment.

As is often the case with transformational ideas, early reactions were negative. When the Journal of Biological Chemistry rejected our manuscript containing data supporting this concept, Boyer told me without animosity that he could see why they would do that — “It was a very striking claim.”

Well, I have never had an idea to compare with this. But sitting through talks that do not light my fire, I have always found conducive to thinking creatively about something else. Its similar to the way that some writers practice their craft better in a coffee shop than in a silent office. Intellectual white noise.

Remember: the best ideas are not in the literature. If they were…..

Those who rent seek on biomedical knowledge wish to seek to define the norms of what is foundational. What is foundational for the practice of medicine should be contested more. Anatomy for surgeons is an easy case to make. But for most non-surgeons, the case for much anatomy is far from simple.

In any historical account of the ascent of modern medicine, Versalius looms large. But this Nature article (Sex, religion and a towering treatise on anatomy) intrigues me for a not so obvious reason: the counterpoint between how such knowledge was represented and understood.

Even Vesalius realized that his images could be confusing, and devised an ingenious method to explain them. A letter or number was printed onto the image of each body part, with a separate key. Unfortunately, the characters were often too small to pick out against the swirling background….

Faced by such challenges, many medics might have given up on the images. Indeed, when we reconstructed what early modern readers and scholars found fascinating about the Fabrica, it was evidently the text. The clear majority of sixteenth- and seventeenth-century readers who annotated the book focused on that and left no traces of having engaged with the illustrations. Sixteenth-century reviews of the Fabrica confirm this impression, because they tended to discuss only the text.

This is no surprise. The Fabrica’s scholarly readership was trained in the traditions of Renaissance humanism, which put a strong emphasis on textual analysis. Even if they found it difficult to interpret visual information, medical practitioners were expert at making sense of long Latin texts.

As the FT reported Monday, the Middle Eastern kingdom expelled the Canadian ambassador, reacting against Ottawa’s support for jailed human rights activists.

Saudi Arabia also said on Monday that it would suspend all its educational exchange programmes with Canada. An official told state television there are more than 12,000 students and their families currently in Canada. They will be transferred to universities and schools in the US, UK, Australia, New Zealand and Singapore, he said.

In English-speaking countries, higher education sectors have become highly reliant on flows of international students. China, which provides over 60,000 new students to the UK each year, is the most commonly cited example. The Saudi Arabian episode serves as a reminder that the trend extends further afield.

The title above and quotes below are from this article by Lincoln Allison. To create teaching machines, you need to make teaching so bad that even the machines can do it. We are almost there.

The most particular annoyance for me was the doubling of seminar size from nine to 18 – allegedly to free up time for research. As if anyone is going to develop the capacity for original thought because they have two or three more hours available in the week! To some of my colleagues, this was merely a technical change, but to me it was the abolition of the real seminar, the thing we should have been most proud of in the English university system.

….

It was part of a general deprioritising of teaching. I remember a colleague looking at her extremely poor ratings on student “feedback” and remarking gaily: “I’m really not very good at this, am I?” She had just had a book published that was extremely well received, and she couldn’t care less that she was failing in her core duties to communicate her ideas within an academic community. Her remark stiffened my resolve to leave – especially once students picked up the vibe about the level of staff interest in teaching and became less challenging and more instrumental.

Much of what I have seen and heard of UK universities in the 14 years since I retired seems to relate to what I would consider proper university teaching about as much as “value” tinned food relates to fresh food. And I think that just as there are people who have never tasted fresh food, there are people who have not experienced real lectures and seminars.

The importance of being sweaty

This looks even more alarming if you factor in humidity. Human beings can tolerate heat with sweat, which evaporates and cools the skin. That is why a dry 50°C can feel less stifling than a muggy 30°C. If the wet-bulb temperature (equivalent to that recorded by a thermometer wrapped in a moist towel) exceeds 35°C, even a fit, healthy youngster lounging naked in the shade next to a fan could die in six hours.

At present, wet-bulb temperatures seldom exceed 31°C.

Link

The first paper I ever published was on sweating. It was my entry as a medical student into dermatology, and the product of meeting Sam Shuster (the rest, as they say, is history). Sweat glands don’t get a lot of attention, but the ~3 million mini-kidneys are full of fascinating biology. Did you know you can shift more fluid through your sweat glands that you can pass urine (quite a thought, considering how many pints of beer some people can manage — and no, I do not have a reference for this factoid so readers beware……).

Anyway I think I get the idea of the wet-bulb temperature, but the above (from the Economist) should give cause for thought. Isn’t skin biology and the environment so endlessly fascinating?
