Last Day of Term!

Posted in Biographical, Education, Maynooth on May 6, 2022 by telescoper

So at last we’ve arrived at the last day of teaching for Semester 2 at Maynooth University. My final session – a revision lecture – was actually yesterday. Today I’m on tenterhooks as the students are submitting their Computational Physics project reports ahead of the deadline of 4pm this afternoon and I’m on hand to help with last minute problems. Some have already appeared on Moodle, bucking the fine academic tradition of only submitting things at the very last minute. Students on this module have to do the project in order to pass the module, so I hope they all manage to submit something by the deadline. I saw a few in the lab yesterday afternoon and they seemed to have good results. I just hope they left enough time to write everything up! No prizes for guessing what I’ll be doing next week: marking project reports (and coursework I didn’t have time to correct earlier).

Next week is a study week for the students, so the powers be must think academic staff are going to be sitting around twiddling their thumbs until the exam period begins (on Friday 13th). That’s the only explanation I can think of for the proliferation of meetings in my calendar for next week.

After that of course my colleagues and I will be marking examinations. I have papers on Tuesday 17th May and Friday 20th May. I may be able to get the first set of scripts marked before the second set arrives, but maybe not. At any rate we have to get all the marks up on the system well before the Exam Boards take place in early June. That should be easy for me, but not so much for those staff who have exams much later in the cycle.

This term has been marked by low attendances at lectures and tutorials, for a number of Covid-related reasons. We’ve done our lectures in person on campus, but only around a third of the students have been attending. Neither I nor anyone else knows what that will mean for the results of the forthcoming examinations. We’ll just have to wait and see…

At least our Exam Board will take place in person this time as the Covid-19 situation here in Ireland looks reasonably positive which will make it a bit easier to discuss any important matters that may arise.

This has been a tough year, with half our lecturing staff being temporary replacements after one departure, one retirement and one on sabbatical. One member of staff will be returning from sabbatical in September, and we have one permanent position under advertisement (application deadline: 22nd May) but we’re going to be forced employ temporary lecturers again next academic year as it seems unlikely the permanent replacement will be in post by September and in any case we will be a post down even if that post is filled. I don’t like this at all, but I have no choice.

Words about Higher Education in Ireland

Posted in Education, Maynooth, Politics on May 5, 2022 by telescoper

Yesterday the Minister for Further and Higher Education, Research, Innovation and Science”, Simon Harris announced a “funding and reform framework” for Ireland which you can find here (PDF).

It’s a typical neoliberal trick to tie “funding” to “reform” because that immediately sends a message that Ireland’s universities are somehow underperforming in some way other than the fact that they are grossly underfunded. The document however admits that there is a huge funding shortfall caused by lack of Government investment over many years, leading among other things to huge student-staff ratios. Perhaps it’s primarily the Government that need reform rather than universities?

That said, I do agree that if extra money is going to be sent to universities, there should be some guarantee that it is spent on the right things: not only academic staff but also, where appropriate, laboratory facilities and so on. Based on my experience in several institutions, typically over half of  university’s budget is spent on central services, some of which are excellent but others of which are expensive and not fit for any purpose at all other than wasting money and causing frustration.

As for the proposals themselves, I’d just say that it is good to have a Minister who recognizes at least some of the problems and is prepared to make positive noises about addressing them. However, the document itself is extremely vague. Look at this, for example, from the
Government’s Press Release announcing the new “landmark policy on funding higher education and reducing the cost of education for families”:

That’s it.

Since the departure of the United Kingdom from the European Union, Ireland’s fees for undergraduate study are the highest in the EU and with the current cost of living crisis (including exorbitant rents) this is in need of reform.  The response however is that the Minister is “committed” only to reviewing (i.e. not necessarily reducing) the fee over some unspecified but probably lengthy timescale.

As with the other items in the “framework” there is no commitment to anything that will halt the immediate crisis currently afflicting students who are struggling to engage and academic staff whose workloads are skyrocketing. In fact I don’t foresee any prospect of material changes before I retire.

Another thing I’ll mention with deep frustration is that there is nothing in the policy about postgraduate education for which there is no framework at all in Ireland and very little funding. It seems Irish Governments just don’t think this is important aspect of what universities do.

Anyway, back to the “policy”, I know that what will actually happen depends on Mr Harris’s success in winning over cabinet colleagues so at this stage he can’t be very specific, but the media somehow dress all this nebulosity up as a policy, which it isn’t: it’s a collection of aspirations.

Warm words, perhaps, but just words nevertheless. We won’t find our for a while whether they actually mean anything.

A Road to Living Documents?

Posted in Open Access, The Universe and Stuff with tags on May 4, 2022 by telescoper

A few weeks ago I posted an item arguing that the scientific paper is an outdated concept and the whole business of research publishing should change to reflect more accurately how science is actually done. I’d argued previously that

the future for many fields will be defined not in terms of “papers” which purport to represent “final” research outcomes, but by living documents continuously updated in response to open scrutiny by the community of researchers. I’ve long argued that the modern academic publishing industry is not facilitating but hindering the communication of research. The arXiv has already made academic journals virtually redundant in many of branches of  physics and astronomy; other disciplines will inevitably follow.

I thought I would explain how the Open Journal of Astrophysics represents a small move in the direction of the “living document” idea.

Recently the author of a paper we published in 2019 contacted me to explain that readers had pointed some errors in that publication and he wished to amend it to correct the mistakes, which were typographical in nature but did propagate through a number of equations though they did not affect the main results. We had dealt with one post-publication amendment in the past and we handled this one in the same way:

  1. The author sent us a new version containing the proposed revisions;
  2. The Editor checked that they were reasonable (i.e. minor and without any significant changes to the scientific content);
  3. After getting the green light the author placed a revised version on arXiv with a comment explanation the revisions (in this case v3);
  4. We changed our overlay to point at the new version.

Here is the new overlay updated this morning.

You will see that there is a note on the overlay after the abstract. There is also a comment alongside the arXiv submission and another in the acknowledgements section of the revised paper. Owing to the separation between the overlay and the arXiv it is not necessary to change the Digital Object Identifier (DOI) or any of the article metadata.

This is a lot easier than the old-fashioned method of publishing an erratum. It may not represent the idea of a living document exactly, but it does demonstrate a way of feeding back to the publication after the “open scrutiny by the community of researchers” I referred to in my quote above.

It also demonstrates that peer review, however thorough, is never perfect and having wider scrutiny can find errors a referee might not.

Astronomical Heads Up

Posted in The Universe and Stuff with tags , , , , on May 3, 2022 by telescoper

You may recall a great deal of excitement about three years ago concerning the imaging of the “shadow” of the event horizon of the black hole in the centre of the galaxy M87. There was so much interest in this measurement that you could hardly move without seeing this picture somewhere or other:

The question I was asked most frequently back then is that there’s a much closer black hole in the centre of our own Galaxy, the Milky Way, so why wasn’t that imaged first? The answer is that the black hole in the centre of M87 is about 1000 times further away from us than the black hole in the centre of the Milky Way – known to its friends as Sagittarius A* or SgrA* for short – but is also about 1000 times more massive, so its Schwarzschild radius is 1000 times larger. In terms of angular resolution, therfore, the observational challenge of imaging the event horizon is similar in the two cases.

I mention this because the Event Horizon Telescope team who made the above image are holding a press conference next week at ESO on “groundbreaking Milky Way results from the Event Horizon Telescope Collaboration”.

I wonder what these “groundbreaking results” might be?

A Dress Code for Physics?

Posted in Biographical, Education with tags , , , , , , on May 2, 2022 by telescoper

This image has been doing the rounds on Physics Twitter recently, accompanied by a mixture of incredulous, amused and angry comments. It’s from the instructions from the 13th International Particle Accelerator Conference (IPAC2022) which takes place in Thailand next month.

To be fair I think this dress code is only for delegates wishing to attend a special event at which the Thai Royal Family will be present, but that it is strange that it should be so “Westernized”. It seems nobody wearing more traditional formal clothing from African or Asian countries, or even Thailand itself would be allowed.

Aside from that, the highly gendered instructions would make many attendees uncomfortable. Women must wear skirts, not trousers for example. Why? I wonder if they’d allow a Scotsman wearing a kilt? It’s all very silly and not at all inclusive. I suspect this nonsense has put off a number of potential attendees.

Speaking for myself, I don’t mind dressing up a bit for special social occasions that have a dress code. At the RAS Club Dinners at the Athenaeum the dress code for men is, amusingly, “jacket and tie”. Trousers are apparently not allowed and there’s no restriction that I know of on female dress. As a matter of fact I find it a relief when the dress code for a function is formal (e.g. “black tie”) because a male person such as me then doesn’t have to think about what to put on. IG wouldn’t like to have a dress code imposed on me at work, though.

The instruction that clothing must be “crisp, neat, pressed and never wrinkled” would represent an impossible standard for most of my colleagues in physics who for the most part dress in a manner that’s more “scruffy academic” than “business professional”. I have however worked with physicists who dress at work in a wide variety of ways. One I remember always wore a three-piece suit (even at the height of summer) and another was full Goth, neither style made any difference to their ability to do research.

I have sometimes been asked by junior researchers about how to dress for things like interviews or conference talks. I wrote about this before, here.

In brief the idea of of dressing up for job interviews in academia has always seemed rather odd to me. The default style of dress for academics is “scruffy”, so it’s a bit odd that we all seem to pretend that it’s otherwise for interviews. I suppose it’s just to emphasize that it’s a formal occasion from the point of view of the interview panel, and to show that the candidates are taking it seriously. I don’t really pay much attention to what interviewees wear, other than that if they look like they’ve just been dragged through a hedge one might infer that they’re  a bit too disorganized even to be a member of the academic staff at a University or that they’re not really putting enough effort into the whole thing.

On the other hand, some people feel so uncomfortable in anything other than jeans and a T-shirt that putting on a suit would either be an unbearable ordeal for them or conflict with their self-image in some fundamental way. Neither of these are intended, so if that’s going to be the case for you, just dress as you normally do (but preferably with something reasonably clean).

I sometimes get asked whether a (male) candidate for a PhD place should wear a suit and tie forsuch an interview. Having conducted interview days for many years at a number of different institutions, my experience is that a smaller proportion do dress formally for PhD interviews than for job interviews. My advice to students asking about this is just to say that they should try to look reasonably presentable, but suit–and-tie are definitely not compulsory. I would say “smart casual” is a good guide, though I have to say I don’t really know what that is. In any case it’s unlikely the staff interviewing you will be dressed formally…

Anyway, in writing this I started to think that the world would be a better place if “business professionals” were made to dress like academics, rather than the other way round.

Lá Bealtaine

Posted in Biographical, Covid-19, Education on May 1, 2022 by telescoper

Today, 1st May, Beltane (Bealtaine in Irish) is an old Celtic festival that marks the mid-point between the Spring Equinox and the Summer Solstice. The month of May is called Bealtaine in Irish and May Day is called Lá Bealtaine. It’s one of the so-called Cross-Quarter Days that lie halfway between the equinoxes and solstices. These ancient festivals take place earlier in the modern calendar than the astronomical events that represent their origin: for example, the halfway point between the Spring Equinox and Summer Solstice is actually next week.

A consequence of all this is that Monday is a Bank Holiday and, in keeping with tradition, the weather has taken a turn for the worse and it is pouring with rain. Nevertheless  Lá Bealtaine shona daoibh go leir!

On the corresponding days last year and the year before I was wondering about how the pandemic would pan out. Back on May 1st 2020 I didn’t think it would last until May 2021 and back in 2021 I did not forecast that we would still have over a thousand new infections every day in May 2022.  The vaccination programme seems to have done its job though and although case numbers remain high, the number of hospitalizations, ICU admissions and fatalities have not increased as in previous waves.

The Department of Health no longer gives Covid-19 updates at weekends (or on holidays) so here is the chart up to Friday 29th April:

May 1st 2021 was around 410 on the time-axis, with cases and deaths falling:

I hadn’t expected the subsequent increase to much higher levels of infection, but the ratio of deaths to cases is much lower now than it was a year ago despite the lower level of testing now.

It was announced on Friday that the Department of Health is to stop giving daily updates. I don’t know if they’re still going to put daily figures on the data hub (which is where I get them from) but if they don’t I’ll discontinue putting data on my Covid-19 page.

Anyway, yesterday’s open day went ahead without physical distancing though some staff and visitors were wearing masks. It was so busy in the Iontas Building that the hubbub made it difficult to be heard while talking with a mask on so I just dispensed with mine for the duration. Some visitors were wearing theirs though.

After tomorrow’s holiday we have four days left of teaching term then there’s a study week for the students – duyring which I’ll be marking computational projects and other assessments – and then the exams begin. For many students this will be their first on-campus examinations and we’re all a bit nervous about how they will go, but we’ll find out soon enough…
