Twyford Waterworks is having it’s end-of-season  open day and steam rally on 4th October 2015. They’re even offering free buses to and from Winchester. You can get there in lots of ways: train to Shawford (with the riverside  Bridge Inn), ride up National Cycle Route 23, walk up the River Itchen, or drive.

While in Twyford, you can shop at the impressive village store or visit the café below. There’s also a tea shop at the waterworks.

Half way between Twyford and the waterworks, Watley Lane heads south up the hill. Keep straight on for 1km up to the top and you’ll reach a strange structure on the right. It was originally built as a water reservoir, then converted into a nuclear bunker for Southern Water. When the cold war ended, it was bought by the internet security firm Symantec who used it as a network operations centre. They outgrew it, and now it’s the home of the Natural Death Centre. Quite a turn-around from nuclear armageddon. If you carry straight on, the track eventually emerges near Marwell.

See you there.

Southampton is holding a Festival of Words from 23^rd October to 1^st November. Sponsors include City College and Arts Council England, but neither of the city’s universities. The Phoenix Film Theatre does, however, get a credit as a “delivery partner”. Many of the events are paid access, at £5 to £10 a head. Of course, if you need free access to a festival-full of words, you go to a public library. The city council is also a delivery partner in the festival but, surprise surprise, none of the events are hosted in the libraries it is trying to close^†. Of these, the council owns two, including the locally-listed Cobbett Road library, which may thus be available for disposal^‡.

For many of us academics, there is something sacred about a library; it plays the same role in a university as the cloisters of an abbey. We perform in a lecture theatre but we study, contemplate and grow in the library. The loss of one is a mark of a retreating civilisation.

Inside our university, there is also a library restructuring under way. Our restructuring is not a cut, but a change in the focus of roles, such as from subject liaison to research, or student, engagement. Such times are always worrying for colleagues. Throughout the development of these changes, our UCU library representative has been fully engaged; we have also supported individual library staff with specific issues. We think, by quietly working alongside university management, we have been able to improve the outcome for both colleagues and the institution. To make sure, we joined Unison (thank you Unison, for both the invitation and the food) in a lunchtime library meeting last week, met several existing members, and recruited another.

Volkswagen have been caught in the United States cheating on diesel emissions tests. They have been using a “defeat device”; the car’s software is programmed to reduce emission of oxides of nitrogen to lawful levels only when it detects the car is actually undergoing emission testing. Most of the rest of the time, it just goes ahead and pollutes.

The US work was conducted by West Virginia University’s non-profit Center for Alternative Fuels Engines and Emissions. The work was paid for by the International Council on Clean Transportation, which is itself a non-profit organization funded by the ClimateWorks Foundation, William and Flora Hewlett Foundation, the Energy Foundation, and the David and Lucile Packard Foundation: yes, the charitable foundations of both the founders of the famous HP electronic test equipment company.

Real-world NO_x emissions were found to exceed the US-EPA…standard by a factor of 15 to 35 for the LNT-equipped vehicle, by a factor of 5 to 20 for one…urea-SCR fitted vehicle.

So why did they do this? Is seems that they were worried that the inconvenience of topping up a small tank of exhaust additive might upset drivers. So, most of the time, they disable the additive injection to stop the reservoir emptying. What is this magic AdBlue solution? It’s a urea and water-based liquid additive; beer drinkers (well all of us, really) will know it by a more common name, and there’s certainly no shortage.

And what are the lessons for us?

1. Corporations cheat. Even trusted high-end companies like VW (they own Porche and Bentley) cheat. And they do so for apparently trivial reasons. Our only protection against corporate cheating is independent, open, research. And government cannot be trusted to hold them to account. Regulatory capture is too easy.
2. The corporate cheats won’t be caught without ready access to skilled, independent, technical analysis; analysis that will only be affordable from independent university researchers. The ability, under tightening budgets and the impact agenda, of university researchers to work independent of wider corporate partnerships is under threat; without it, there will be nobody to catch the next Volkswagen.

Update: It seems Volkswagen were not just economising on AdBlue. Apparently, fully enabling the NO_x controls will prevent the cars achieving their claimed performance.

And a professional note: This is almost certainly a company conspiracy, not a rogue employee. The engine-control software is safety-critical. It must have been subjected to extensive internal review. Sampling the steering to decide how to dose the exhaust should raise an immediately obvious issue.

The Butcher’s Hook is a tiny new pub in the Bitterne Triangle, opposite the clock tower. Just go on down St Denys Road from Portswood, cross the river, and it’s directly ahead. The building was originally a butchers, and most recently a flower shop. The beer is varied and good, served straight from the barrel. It attracts a younger clientèle than the Guide Dog, and is always full.

If you actually want a butchers, the posh one around is Uptons of Bassett,  in the opposite direction from the university.

The pub was opened by a young team who we watched spend several months renovating and converting the old shop themselves. At one stage, I was even asked about doing some electrical work; I couldn’t, as I don’t carry the right insurance. There is a University (ECS) connection as they are old friends of Rob Spanton, of Student Robotics fame.

To make a day of it, you can come in for a couple of pints after a walk along the River Itchen (from Winchester if you are fit); just continue on south from Woodmill through Riverside Park until you reach the bridge.

The web carries a remarkable amount of nuclear weapon design information, of varying accuracy and provenance. Carey Sublette (I think this is he) has written a popular FAQ; it includes the graph above. What has this to do with change? Well, according to his explanation, if you have to explode a ball of Uranium, you need to squash it smaller. If you squash it enough, it becomes critical and (usually with a little help) starts a chain reaction, leading to an explosion. When you squash anything, it gets hot and tries to expand. Ideally, you would compress it so slowly that the excess heat leaks away as you press. That’s always far too slow for a bomb. The best you might hope to manage is to press steadily, so that all of your effort goes into shrinking the bulk.  You’ll know you are being steady enough because, if you steadily release the pressure, the ball will return to its original size and temperature; the compression is reversible or adiabatic. To get enough compression to detonate the bomb, however, you need to use a shell of explosives. Typically, that will not achieve a steady compression; it will create sonic booms or shock waves: enormously powerful sounds that will bounce around the ball, heating it up and making it expand. The ball gets far hotter than you would wish and you need to use too much explosive energy. Brute force generates a great deal more heat than light. In consequence, expert bomb designers use tricks to make the compression as reversible as possible.

There is a universality (the second law of thermodynamics) about the efficiency of steady, reversible, change. I think it applies also in the management of human endeavours. Steady change gets us where we need to be with the minimum of wasted heat and energy. Shock change generates more heat than light, and is inefficient.

INEX REVIEW The InEx Review is a University-wide review of income and expenditure. As the Vice-Chancellor explained in his letter to staff, (4 April 2008) this is a necessary and unavoidable response to the challenge posed by operating in an increasingly competitive environment at a time when the University’s income is not keeping pace with expenditure.

Shock change has happened to us before; I hope it doesn’t happen again with the PwC review, and the arrival of a new VC, DVC and COO. Whatever happens, UCU will be here to try to keep things as cool as possible.

I went to a great lecture by Nick Chater of Warwick Business School this morning. I have found most of his slides online, and thought I might share one with you. His thesis was that Nash (A Beautiful Mind) Equilibrium is insufficient to describe real human behaviour. He developed a broader concept which he called Virtual Bargaining. Much of the talk was taken up by examples^† in which the Nash equilibrium behaviours are either obviously ridiculous, or just not what people do. For trade unionists, the most interesting example was an experiment^‡ from 1998. There are three players: A, B and C. Player A has £100 to distribute among the three of them. He selects a distribution and then B either vetoes it or agrees to it; if she exercises the veto, nobody gets anything. Nash tells us that A should keep £99 for himself, offer a £1 sop to B, and give nothing at all to C. B should accept her £1, as it’s better than nothing.

Let’s make it more fun by renaming the players. A becomes bosses, B becomes trade unionists, and C becomes non-unionised workers. As in the real world, the bosses make an offer, we in the union accept or reject it, and those without a union have to take what they are given. So what actually happened in the experiment? After a little practice, the bosses settled down to offer roughly £60 to themselves, £30 to the unions, and £10 to the others. Nick’s message was that Nash equilibrium often does not correspond to real human behaviour. We trade unionists can draw another lesson. If you’re not in the union, you’re not in the decision, and you will be ripped off. You’ll see about a third of what you might reasonably expect. In the union, we get what looks like an almost fair offer. But that hides the fact that the bosses, by depriving others, are taking twice what they give us.

As I have written before—you need to join UCU. Now. Join here.

Jo Johnson, the Minister for Universities and Science, gave an interesting speech last Wednesday  to Vice Chancellors gathered at the University of Sussex. It makes challenging reading for the Russell Group.

Because many universities see their reputation, their standing in prestigious international league tables and their marginal funding as being principally determined by scholarly output, teaching has regrettably been allowed to become something of a poor cousin to research in parts of our system.

I hear this when I talk to worried parents, such as the physics teacher whose son dropped out at the start of year two of a humanities programme at a prestigious London university, having barely set eyes on his tutor. Her other son, by contrast, studying engineering at Bristol, saw the system at its best: he was worked off his feet, with plenty of support and mostly excellent teaching.

He also quoted Palfreyman & Tapper^†, based on US work by Armstrong & Hamilton^‡:

…the faculty cultures and orientations of the college professoriate have much to answer for, since they have struck a disengagement contract with their students, along the lines of I don’t want to have to set and mark much by way of essays and assignments which would be a distraction from my research, and you don’t want to do coursework that would distract you from partying: so we’ll award you the degree as the hoped-for job ticket in return for compliance with minimal academic requirements and payment of high fees.

Depressingly, there is a lot of truth in these remarks. There is an assumption, in our and other universities, that teaching should be loaded onto those who cannot raise research funds or REF stars. Teaching is culturally associated with lack of success; every young academic knows that their promotion, or next job, will depend only on their grants and publications. So, the ambitious ones waste as little time as possible on teaching: just enough to stay out of trouble. Anything better is a result of personal vocation. Favoured sons and daughters are further rewarded with light teaching loads or with leeway about completing their duties.

National structures to enhance and recognise university teaching are not much better. The Institute for Learning and Teaching in Higher Education, inspired by the Dearing Report,  lasted from 2000 to 2004. We now have the Higher Education Academy, but it is to lose all its central funding by 2017. Within my own department, several colleagues achieved Senior or Principal Fellow status in the HEA; all have since been removed from teaching management responsibility.

Neither will you find either of the books cited below in our library; we’re not expected to read that sort of thing. There are, however, some works by Tara Brabazon; you might try The University of Google or Digital Hemlock.

Update: The library will be getting both. Thank you, Fiona.

There must be room here for the UCU to become a proper professional body. We already have our own Journal of Further and Higher Education. Have any of you read it? But UCU Congress shows far more interest in arguing over regional committee structures and splitting of branches than it does in the credibility of our profession. Can we inspire UCU to step into the void to be left by the HEA and become the BMA of higher education?

We all find Mondays difficult. But I couldn’t resist drawing attention to the university’s Monday posting about the ongoing pay dispute. It didn’t go well.

1. The current pay round is 2015/16; the 2014/15 round was settled quite a while ago.
2. Unison is not in dispute; Unite is.
3. I don’t think we are opening a Shetland Campus. So the University is not in dispute with the Educational Institute of Scotland either.

A small prize to members who spot any more errors.

Meanwhile, back at 47 University Road^†, iSolutions had disabled printing for all the unions. Thank you, Lindsay^‡ for fixing it within a day or so. It has been a difficult week.
