Just last week, when faced with a report that its advertising numbers promised an American audience that, in certain demographics, well exceeded the number of such humans in existence, judging by U.S. Census Bureau numbers, Facebook told the Wall Street Journal that its numbers “are not designed to match population or census estimates. We are always working to improve our estimates.” Facebook’s intercourse with the public need not adhere to the so-called norms of so-called reality.

So the opportunity for that is huge.”

Its housing, but not as we know it.

The developers can get away with such things, because student housing doesn’t officially classify as housing. It falls into the murky category of “sui generis” (Latin for “of its own kind”). As it falls outside a specific use class, it doesn’t have to adhere to the usual standards associated with dwellings (class C3). Local authorities differ in the their approaches, but student accommodation is usually either treated as a hotel (C1) or residential institution (C2), the same category as care homes, hospitals and boarding schools. Due to their limited occupation, these building types are immune from many of the codes that govern residential dwellings – from space standards to daylight and acoustics. At the same time, crucially, the developer is exempt from providing any contribution towards affordable housing.

I was browsing through some old noes and came across this:

Third, we’re convinced that medical education and training must be reinvented to adapt to the changing health care paradigm. We think that AHCs should reexamine traditional beliefs and approaches to medical education, questioning its cost and duration. Should education shift toward using dedicated instructors, increased online instruction, simulation, even gaming? Can AHCs shorten training time by streamlining the educational continuum — for example, providing a focused 3-year medical school curriculum in primary care, plus a 2-to-3-year residency?

“It’s not that the undergraduate education is better at Ivies than at other private universities. (In fact, Ivies almost certainly provide a worse education than many obscure liberal arts colleges that may have loose admissions standards but provide very intensive and personal instruction.) It does mean that, in the current budget situation, pretty much any private college will provide a much, much better education in the liberal arts and social sciences than any public university — except the rare ones that operate like liberal arts colleges, like William & Mary or SUNY-New Paltz.

This wasn’t always true. (In 1970, Berkeley spent 70 percent as much per student, from all funding sources, as Stanford. As of a few years ago the figure was 30 percent and now I bet it’s more like 20 percent. With those numbers, there’s no way that the private-public distinction is a matter of fancy gyms and climbing walls.) I wish it weren’t true now. And none of this necessarily means you’re wrong about how to fund higher education: subsidizing students to attend the Ivies in some ways may widen the gap I’ve just mentioned.”

One thing about trying to put the Internet and computing in context, is that you are forced to look back at the history of other communication revolutions (pace Tim Wu, John Naughton etc). It is now a well trodden path, but one I still find fascinating. Even down to the details of how the cost of distributing images or 3D moulages had an effect on my own specialty. The following caught my eye — or maybe my nose.

“When paper was embraced in Europe, it became arguably the continent’s earliest heavy industry. Fast-flowing streams (first in Fabriano, Italy, and then across the continent) powered massive drop-hammers that pounded cotton rags, which were being broken down by the ammonia from urine. The paper mills of Europe reeked, as dirty garments were pulped in a bath of human piss.”

“Physical exam skills are eroding fairly significantly. We see that year after year. The masters who taught us are gone, and we’re not teaching the people below us well enough, for all the reasons we talked about.

At the same time, we grossly overestimated the average clinician’s ability to do an extremely good physical exam and to make all of the relevant physical findings. It has been documented over and over again that the average person’s ability to use a stethoscope and document a murmur accurately is a coin flip. The ability of the average house officer to do volume assessment based on a physical exam is terribly low.”

“Taking notes on laptops rather than in longhand is increasingly common. Many researchers have suggested that laptop note taking is less effective than longhand note taking for learning. Prior studies have primarily focused on students’ capacity for multitasking and distraction when using laptops. The present research suggests that even when laptops are used solely to take notes, they may still be impairing learning because their use results in shallower processing. In three studies, we found that students who took notes on laptops performed worse on conceptual questions than students who took notes longhand. We show that whereas taking more notes can be beneficial, laptop note takers’ tendency to transcribe lectures verbatim rather than processing information and reframing it in their own words is detrimental to learning.”

Minute particulars

This is from an article in Nature. And the problem is resolving differences in experimental results between labs.

But subtle disparities were endless. In one particularly painful teleconference, we spent an hour debating the proper procedure for picking up worms and placing them on new agar plates. Some batches of worms lived a full day longer with gentler technicians. Because a worm’s lifespan is only about 20 days, this is a big deal. Hundreds of e-mails and many teleconferences later, we converged on a technique but still had a stupendous three-day difference in lifespan between labs. The problem, it turned out, was notation — one lab determined age on the basis of when an egg hatched, others on when it was laid.

Now my title is from Blake:

He who would do good to another must do it in Minute Particulars: general Good is the plea of the scoundrel, hypocrite, and flatterer, for Art and Science cannot exist but in minutely organized Particulars.

And yet, I think I am using the quote in a way he would have strongly disagreed with. Some of the time ‘Minute particulars’ are not the place to be if you want to change the world. Especially in biology.

If you are interested in the history of science. Or put another way, how science can work when it is allowed to, check out this wonderful site: ‘Molecular Tinkering: How Edinburgh changed the face of molecular biology’.

I first became aware of ‘Edinburgh’ and its role in molecular biology by accident. In the late 1970’s I spent three months here doing a psychiatry elective, on the unit of Prof Bob Kendell. I stayed in self-catering University accommodation through the summer, knowing nobody, spending most of my free time tramping around the city on foot. Not always bored. There was a motley crew of people staying in the small hall, and one was a biologist from China. I had never met anybody from this far away and mysterious place. Of course, mostly I asked about barefoot doctors and the like, and questions that you would not now use your mobile phone to ask. No Alexa then. But I wondered why he was here. Molecular biology, he explained. Now, I could recite the story Jim Watson told about Watson and Crick, and even mention a few names who followed. But no more than a handful. ‘Recombinant DNA’ might have passed my lips, but please do not ask me to explain it. But from him, I learned something special has awoken. And for me it was literally a couple more years before the waves of this second revolution broke on the shores of MRC Clinical Training Fellowship applications.

A sample:

Throughout the 20th century film editors worked by identifying key scenes in their film reels, snipping precise frames and re-joining them to create a new narrative. This is exactly how the Murrays wanted to work with the long molecules of DNA. Restriction enzymes would be the editor’s scissors, making the cuts. As well as doing the cutting, the enzymes would be the editor’s eyes: recognising the precise frame at which to snip.

Or if you ever doubt that the space for discovery is infinite, listen to this from Noreen Murray:

“Looking back, it is amazing that Ken and I were the only people in the UK in the late 60s and early 70s to notice the potential of restriction enzymes.”

Or this, for a definition of what research leadership is all about:

Waddington had a real knack for selecting and recruiting interesting but often unproven biologists.

Profit over prophet

I actually found this quite witty. But it is more than that. It playfully raises some of those issues about education, assessment, and certification. I would love to say medical education has got this right, but I do not believe that. It is easy to list the problems, but hard to solve them. Numbers and formal systems will always be used by those who understand them least, to exile judgement.

  1. Foundational knowledge does exist, it is just not as common as many believe. Teachers, accreditors and other institutions always want to exaggerate the importance of foundational learning because they rent seek on it: the more there is, the more money they make. They will create a world which suits them. It is not just the world some of use live in.
  2. Assessment may drive learning, but assessment frequently wrecks the learning that is education. I post this on the day that the ‘O’ level results come out: education as a proxy war for  politicians seeking reelection.
  3. Demands for better ‘metrics’ will often come at the cost of what many consider most important. Defending exam procedures, may lead to a quasi- legalistic obsession with reliability at the expense of education. This is not a new problem, and is far broader than psychometrics and indeed permeates much science (see Cornfield, J., & Tukey, J. W. (1956). Average values of mean squares in factorials. The Annals of Mathematical Statistics, 27, 907–949). The danger is people think that metrics are ‘theory free’ and forget that in education (and many other domains) metrics causally alter subject behaviour.
  4. Education is about the future. Any designer or educator has to live in the future. And since most of have enough difficulty understanding the present, we can only see it using metaphor. Blake said it well: every honest man is a prophet. Universities increasingly like to spell that sound with different letters.

For British academics, and probably students too, the heyday of university life came straight after the Second World War. British universities, tiny and cosy by today’s standards, enjoyed enormous autonomy over degree content, expenditure and admissions. Wealthy Oxford and Cambridge enjoyed the highest prestige, but there was no fixed hierarchy, and the standards for a first-class degree seem genuinely to have been quite uniform across the sector.

None of this could survive rapid expansion.

Passwords

by reestheskin on 21/08/2017

Comments are disabled

Awhile back the University of Edinburgh changed some of their guidance around passwords. In my 1Password app, I counted over 250 passwords. Some of these are old and no longer used, but the large number reflects the nature of academic life, in which information and knowledge flow is more outside the institution than within it. My bugbear is of course the NHS and the practice of making people remember hard passwords and change these passwords every 3-4 weeks. This is just bad practice, and leads to people writing them down close to where they use them, or choosing more guessable passwords. Another example of bad practice is below.

Slashdot asks if password masking — replacing password characters with asterisks as you type them — is on the way out. I don’t know if that’s true, but I would be happy to see it go. Shoulder surfing, the threat it defends against, is largely nonexistent — especially with personal devices. And it is becoming harder to type in passwords on small screens and annoying interfaces. The IoT will only exacerbate this problem, and when passwords are harder to type in, users choose weaker ones.

Veblen’s conspicuous consumption rides on:

Rather than filling garages with flashy cars, the data show, today’s rich devote their budgets to less visible but more valuable ends. Chief among them is education for their children: the top 10% now allocate almost four times as much of their spending to school and university as they did in 1996, whereas for other groups the figure has hardly budged.

Well, I thought the Swiss connection with Sherlock Holmes were the Reichenbach falls (I had to visit, a few years back). But no, I read that:

Except in Switzerland, where the stories were banned from railway bookstalls for fear they’d inspire criminality, Sherlock Holmes was big business from the moment of his inception.

But of more interest to the medic:

In 1882, as a newly qualified doctor with a practice in Southsea, Arthur Conan Doyle found himself chronically short of sick people. He therefore used the empty office hours to write his tales about the “consulting detective” who was based on Joseph Bell, the Edinburgh surgeon who knew at a glance what was wrong with the patients parading before him

There is a widespread delusion in the UK that you can accurately plan how many doctors you need. This is a mistake, both for society and for the doctors themselves. As we move forward, I think we will see more medics emulating one of the great ones.

And, as for the book, reviewed in the FT (‘The life and death of Sherlock Holmes’), it highlights that Holmes’ nemesis was not Moriarty, but lawyers.

“A couple of months ago I quoted this phrase from Sam Altman:”

Plotting the future | Status-Q

I talk about a variant of it that I thought Larry Summers used, although when I have tried to check my memory, I turn nothing up. I see two straight lines, one with a shallow gradient close to zero, the other with a steep one, joined at an inflection point. When you are on the shallow line, you never perceive anything is changing. And even when you know things are going to change  — or you wish for change —you have no idea when. At least with an exponential function you can calculate: with a sudden shift, all you can do is pray. An optimist is somebody who wishes the inflection point comes soon. As does the fool.

WHAT do you call someone who is over 65 but not yet elderly? This stage of life, between work and decrepitude, lacks a name. “Geriactives” errs too much on the side of senescence. “Sunsetters” and “nightcappers” risk being patronising. Perhaps “Nyppies” (Not Yet Past It) or “Owls” (Older, Working Less, Still earning) ring truer.

I am OK with soon (as in the David Bowie song) being patronised. I like ‘sunsetters’ best. Sipping G+T watching the sun go down, in Africa.
