Before Phase Three..

Posted in Biographical, Covid-19, Maynooth with tags , , on June 28, 2020 by telescoper

Tomorrow (on Monday 29th June) Ireland will enter Phase Three of its (accelerated) Roadmap for Reopening after the Covid-19 restrictions.

The Coronavirus situation here remains relatively stable, with new cases steady at a low level:

This is not the case for the rest of the world, however. Yesterday two grim milestones were passed: 10,000,000 confirmed cases of Covid-19 worldwide and 500,000 deaths:

Much of the recent numerical growth of the pandemic is associated with North and South America. Brazil is particularly badly affected as are some of the United States. I don’t need to comment on the quality of the political leadership involved.

I am very nervous about the situation in the United Kingdom too, where I feel the reopening is being rushed. Poor leadership is partly responsible for the continuing high levels of infection there too.

Anyway, back to Phase Three in Ireland. Yesterday I bought a copy of the Irish Times and found this booklet inside:

The emphasis is on the fact that despite the low levels in Ireland Covid-19 has not gone away and we all have to be prepared to take special precautions for the foreseeable future. I would be amazed if there wasn’t another flare-up here at some point, actually, it’s just a question of when. And those optimistic about the delivery of a vaccine in the near future, I’ll remind you that there isn’t yet a vaccine for any form of Coronavirus let alone the novel form responsible for Covid-19 (SARS-CoV-2).

Anyway, on Friday I attended a virtual Question and Answer session with the President of Maynooth University, Professor Philip Nolan, about the plans for reopening campus over the Summer and into the new academic year. It is clear that lots will have to be done before staff can return fully and even then it won’t be anything like “normal”.

Incidentally the issue of face masks came up and there was some discussion about their effectiveness. Not being a medical expert I don’t really know about that, but I think one of the important things about masks in a work environment is that their visibility means that they work as a signal to remind people to be aware of Covid-19. I have discarded my home-made face masks and bought a box of proper ones and I intend to wear them whenever I am in a work setting in which anyone else is present.

On Friday evening I finally received (relatively) detailed instructions on how the return to work process will work. The Department of Theoretical Physics at Maynooth University is still basically in Phase 1 while the university working group has been assembling this guidance. It will probably be several more weeks before we can get people back to work because there are many things still to be done: including the installation of hand sanitizers, one-way systems, screens, and new signage.

Another thing that came up during the President’s Q&A was the question of vacations for staff. Fortunately I had muted both my audio and video feeds for this as I laughed out loud. What with organising the return to work, overseeing repeat exams, recruiting a sabbatical replacement, planning teaching for next year, rewriting my own lectures for the “new normal”, etc etc, and (hopefully) moving into a new house, I can’t see any prospect of any summer holiday this year at all!

Scrambled Phases

Posted in Biographical, Covid-19, Maynooth with tags , , , on June 22, 2020 by telescoper

A couple of weeks ago I posted about the imminent start of Phase 2 of the Irish Government’s Roadmap for Reopening after the closures enforced because of the Covid-19 pandemic.

Since then the Irish Government has decided that there will only be four phases instead of five, and many elements of the programme will be moved forward. For example, all travel restrictions within the Republic will be lifted from next Monday (29th June), which is when Phase 3 is due to commence. It has also been announced that hairdressers, barbers, nail and brow salons, beauty salons, spas, make-up application services, tanning, tattooing and piercing services will re-open. I find that surprising, as I find it hard to see how such services can be provided at low risk of transmitting Covid-19.

In fact I find the whole idea of accelerating the Roadmap rather worrying. I hope I’m proved wrong, but it seems to me that the Government is rushing this. There are worrying signs in Germany that the R-number is increasing significantly and undue haste in opening business may lead to a similar rise. It must be stressed that the number of cases involved in Germany  is rather small and most are confined in local outbreaks that can be contained. Nevertheless, this remains a concern.

At the moment the situation looks stable, with new cases at a very low level:

I do worry however that, since only a very small fraction of the population (at most a few percent) have been infected with Covid-19, there will be very little resistance if Covid-19 starts to spread again.

As for my own work situation here at Maynooth University, what happens in Phases Three and Four is all a bit hypothetical, because we’re still stuck in Phase One! The University management is being extremely cautious about allowing anyone back to work at all until various protocols are agreed, risk assessments carried out, and staff training delivered. It seems likely therefore that we will reach Monday’s scheduled start of Phase 3 before we are even ready for Phase 2. In practice, therefore, the various phases of the Roadmap are no longer relevant in this particular setting. I think I’ll remain the only person coming in to the Department for quite some time!

I fully understand and support the careful approach adopted  by the University, of course, and the delay doesn’t matter that much as our teaching semester is now finished and, being theorists, we can all work from  home reasonably effectively. It must be more of a challenge for laboratory-based researchers. My main concern is  I’d be very surprised if all the other organizations and businesses due to open next Monday are as cautious. The last thing we need for people to cut corners and send us all back to square one.

 

Psychological Time

Posted in Biographical, Covid-19, Education with tags , , , on June 21, 2020 by telescoper

So, the Summer Solstice for 2020 is now in the past. It’s all downhill from here!

As the Solstice approached last night I was thinking back to the Vernal Equinox which had happened this year on March 20th, exactly three months before. That was at the end of Study Week in the Spring Semester but the students did not return the following week and we switched to remote teaching. I find it astonishing to think that was just three months ago. It seems like ancient history. Not only that but several major events took place during that period that I find it hard place in chronological order without looking at written records (including this blog).

I am not an expert on such matters but it seems to me that the isolation, disruption of social interaction, and the loss of familiar routines imposed by work are among the things responsible distorting perception of the passage of time. I have tried to impose a regular pattern on my day during this time but only with limited success. I suspect it’s not only me who has felt like this over the past weeks and months!

It’s not just the disruption to routine of course. There was also a genuine fear of becoming infected. My last in-person lecture was on 12th March, the Thursday before Study Week. From time to time I wondered if I would ever see those students again. I also made arrangements to write a will. For a time it looked likely that intensive care facilities in Ireland might be overwhelmed so I felt it important to make contingencies of that sort. Fortunately they weren’t needed. As far as I know the Coronavirus hasn’t reached me. I certainly haven’t had any symptoms, though I haven’t actually been tested.

Overall I found the lockdown very difficult at first but I think adjusted reasonably well despite (or perhaps because of?) having very peculiar dreams.

Now that the Covid-19 restrictions are gradually being wound down hopefully some measure of routine will resume and the sense of disorientation will fade. Time will tell.

Challenges Past and Future

Posted in Covid-19, Education, Maynooth with tags , , , , , , on June 19, 2020 by telescoper

Yesterday afternoon we held our Departmental Examination Board in Theoretical Physics (via Microsoft Teams*) which all went remarkably well in the circumstances.

The most challenging thing to happen yesterday afternoon was that a bloke came to cut back the bushes outside my office with a very large and noisy hedge trimmer. I thought I was going to have to contend with that all afternoon but it seems he had done most of it the day before and only came back yesterday to finish off. He left before the Exam Board started.

The next stage of our Exams process is for all the Departmental results to be collated for those students on joint programmes before the final University Board takes place about ten days from now. After that students will get their results.

That doesn’t quite finish examination matters for 2019/20 however because some students will need to take repeat examinations in August. These will be a week later than usual as a knock-on effect of the extra week we were given to mark and correct the May exams. We anticipate that at least some of the repeats will be the traditional `in person’ on campus style, but some may be online timed assessments like the ones we held in May. That depends a bit on how the Covid-19 pandemic pans out in Ireland over the next few weeks (and of course how many students actually take repeats, as social distancing generates a capacity issue for the examination halls).

At the moment we are optimistic because the number of new cases of Covid-19 is low and stable. That coulld change, of course, if the virus starts to spread again so we have to have contingency plans.

Even more uncertain is what will happen in September, although I have been very annoyed by some reports in the media that seem to have been actively trying to put students off coming to University next academic year on the grounds that there won’t be any lectures. We certainly plan to offer as much face-to-face teaching as possible and I think other third-level institutions in Ireland will do likewise. There will of course have to be a backup if there is another lockdown, which may mean switching back to remote teaching at relatively short notice, but at least we’ve done that once already so know much better now what works and what doesn’t. Nevertheless I would encourage all potential students not to believe everything they read in the media nor be deterred from attending university by rumours from sources who don’t know what they are talking about.

Earlier this week I was starting to think about how we might build the required flexibility into our teaching for next year and two main things struck me.

The first is that while we have more-or-less been forced into making various kinds of video material available to students, this is something that I feel we should have been doing already. I’ve long felt that the more types of teaching we incorporate and the wider range of learning materials we provide the better the chance that students find something that works for them. Even if we do have a full programme of lectures next year, it is my intention to continue to provide, e.g., recorded video explainers as well because they might augment the battery of resources available to the student.

Some time ago I had to make some policies about `reasonable adjustments’ for some disabled students learning physics. In the course of providing extra resources for this small group I suddenly thought that it would be far better, and far more inclusive, simply to make these resources available to everyone. Likewise, we’ve been forced to adjust to providing material remotely but we should be thinking about how to keep the best things about what we’ve done over the last few months and embedding them in the curriculum for the (hopefully Coronavirus-free) future and not regard them all as temporary special measures.

The other thing that struck me is in the same vein, but a little more speculative. Over the last many years I have noticed that students use printed textbooks less and less for learning. Part of that may be because we in a digital age and they prefer to use online resources. The switch to remote learning has however revealed that there are some students who are disadvantaged by not having a good internet connection. I just wonder whether this might lead to a resurgence in the use of textbooks. I’ll certainly be making a strong recommendation to the new first-year students in Theoretical Physics that they should get hold of the recommended text, which I have previously regarded as an optional extra.

*At one point I got muddled up between Teams and Zoom and called it Tombs. It was a grave error, but it can only be a matter of time before Microsoft Tombs actually arrives…

Meanwhile, in Ireland…

Posted in Covid-19, Education, Politics with tags , , , , , , , on June 17, 2020 by telescoper

It seems an eternity since we had the 2020 general election in Ireland on February 8th because of the intervention of the Covid-19 outbreak, but it’s still been over four months. Now however it seems we might have a new government fairly soon, as a deal has been agreed to form a coalition between Fine Gael, Fianna Fáil and the Green Party; between them these parties have 84 seats (not counting the Ceann Comhairle), enough to create a majority in the Dáil Éireann. It’s not quite done and dusted, though, as the Green Party has to ballot its membership and a two-thirds majority is needed to endorse the agreement. We should know next week.

In case you think this delay means that Ireland has been in political crisis since February, it hasn’t really. The constitution makes it clear that if a new government can’t be formed the old one continues until one can (or until another election can be held). Leo Varadkar has continued as Taioseach in the mean time. His popularity has increased in this period, at least partly because as a trained medical person, he is perceived to have handled the Covid-19 crisis rather well. It seems that incumbents have generally received the backing of the public when they have coped reasonably with the pandemic. Whether that continues in Ireland remains to be seen. When the truth comes out about how many patients were transferred from hospitals into nursing homes where they were left to die perhaps opinions will change.

It has taken over four months for the the parties to agree a `draft programme for government’ which you can find here. That document is 139 pages long but largely devoid of concrete commitments and indeed devoid of anything other than vague discussions, platitudes, and `reviews’. At a quick reading I’d say the Greens have been far more effective at getting their agenda into it than Fianna Fáil, perhaps because the latter don’t really have an agenda other than wanting to be in power. The Green initiatives are in my opinion the strongest parts of the programme, but the rest seems to me to be just “more of the same”.

I’d say that the one redeeming factor is the document is the emphasis on stimulus rather than austerity as a way out of the current crisis but of course that may turn out not to be what actually happens.

From the point of view of Ireland’s universities and research community there is little to rejoice. On page 114 you can find this:

Higher and Further Education have been greatly affected by the COVID-19 crisis and we will support the sector through these challenges to ensure that educational opportunities remain and are made more accessible to everyone, particularly the most vulnerable in our society. In addition, we will continue to support our research community to tackle the social and scientific problems posed by COVID-19 now and into the future.

We are committed to addressing the funding challenges in third-level education. We want a Higher and Further Education sector that sees education as a holistic and life-long pursuit. We will continue to build strong connections with other education sectors and wider society, while recognising our global and environmental responsibilities. It is vital we invest in our Higher and Further Education sectors so we can continue to tackle inequality based on race, gender, and socio-economic background. We recognise the potential for our Higher and Further Education institutions to be exemplars regionally, nationally and internationally.

At a time of great economic uncertainty, when so many people fear for their future employment, we will ensure that Higher Education plays a vital role in our recovery. We will equip students with the skills necessary to secure employment, while preparing for the opportunities and challenges posed by a changing economy, the move to a low-carbon future and disruptive technologies, as well as offering retraining and reskilling opportunities to help people into employment.

Warm words at the start and then a worryingly blinkered emphasis on universities simply as providers of skills training. We do that of course, but we do so much more that Irish governments seem not to recognize.

Later on we get a commitment to

Develop a long-term sustainable funding model for Higher Level education in collaboration with the sector and informed by recent and ongoing research and analysis.

Sigh. There’s been an OECD Report (2004), the Hunt Report (2011), the Cassells Report (2016), etc. How many times will this issue be kicked into the long grass?

The Fianna Fáil `pledge’ to introduce a Minister for Higher Education and Research has, needless to say, fallen by the wayside in the negotiations.

The plan for the new Government is that the plan is as the leader of the largest party in the coalition, Fianna Fáil, Micheál Martin will take over as Taoiseach for two years, after which Leo Varadkar will return. This is being referred to as a `Rotating Taoiseach’, which is a pretty apt given that the programme has more spin than substance.

Songs of Comfort and Hope

Posted in Covid-19, Music with tags , , on June 12, 2020 by telescoper

I was just looking back at a post I wrote early in the New Year and saw that top of the list of things I resolved to do more of in 2020 were (1) to go to more live concerts and (2) to see more of Ireland. Unfortunately the Covid-19 Pandemic put paid to both of those (and the other things on the list too). I haven’t listened to live music since March and haven’t set foot outside Maynooth in that time either!

Anyway, someone at the National Concert Hall in Dublin hit on the idea of putting on live concerts without an audience. I wasn’t sure it would work but based on this concert, broadcast a couple of weeks ago, and now available as a recording on Youtube I think it does. This recital features wonderful Irish mezzo-soprano Tara Erraught and pianist Dearbhla Collins in a programme of songs by Franz Liszt, Franz Schubert, Aaron Copeland and Richard Strauss followed by some Irish folk songs. I think it’s a lovely performance, and I found the setting of an empty hall unexpectedly moving.

Marking Time

Posted in Covid-19, Education, Maynooth with tags , , on June 12, 2020 by telescoper

In among all the other things I have to do I’ve just finished marking my portion of examinations and other assessments in time for next week’s Examination Boards. I have to attend two (virtually), one for Theoretical Physics and one for Engineering Mathematics. You may recall that, this year, along with many other universities, we switched from the usual examination format to online timed assessments.

Obviously I can’t talk about any actual results here but I can relay a few general points.

First, there were remarkably few hitches in the examination process. I would like to say that I was totally confident that the new system would work, but I’m afraid I was very nervous during the examination period. I’m glad that I was proved wrong. That’s not only due to very hard work by the teaching staff in getting everything together to go online and the technical support staff for ensuring the submission portals could handle the load, but also due to the students who coped admirably well with the new assessment style.

That said, I think if we are going to have such assessments again in the future there are things we could improve.In particular the mathematical nature of our work means that students have to do their working, diagrams etc by hand and sometimes the quality of scanning made the resulting submissions very difficult to read. If we had had time we could have offered more training to the students on how to scan their work more legibly, so next time we will probably do that too. Indeed we will probably be doing most of the coursework that way next term so they will probably get more practice anyway.

Printing the work out usually made the legibility problem worse, so I generally marked as much as I could on the screen. We don’t have very good software for doing this in bulk so it was painfully slow. I estimate it took me about three times as long to mark an examination script this way than doing it on paper. I’d be very interesting to hear via the comments box of any suggestions or recommendations of software to help this process!

The main purpose of this post however is to say a very public thank you to all the teaching staff in the Department of Theoretical Physics and to our admirable Departmental Administrator Suzie  for working so hard in difficult circumstances to get everything done in time!

 

 

 

 

Time for Phase 2 in Ireland

Posted in Covid-19, Maynooth with tags , , on June 7, 2020 by telescoper

Tomorrow (June 8th) sees the start of Phase 2 of Ireland’s Roadmap for Reopening. You can see that, as of yesterday, the number of confirmed cases per day is small and stable after three weeks of Phase 1, which has justified proceeding to Phase 2.

Incidentally, since the Covid-19 outbreak took hold in Ireland there have been daily press briefings by the Department of Health. Yesterday’s was the last of these: from now on the updates will be twice a week, on Mondays and Thursdays. Data will still be released every day but there won’t be a press conference every time. I’ve been following these every day for three months so this will be quite a change to the routine!

Moving to Phase 2 means that most shops will be able to reopen (subject to social distancing measures being in place), people will be able to travel much further (anywhere within your own county and 20 km into another) and there will be a limited return to work (subject to the completion of various protocols, risk assessments, etc).

For us at Maynooth University there won’t be a sudden change. Staff who can will continue to work from home (which is basically everyone in the Department of Theoretical Physics) but labs will gradually reopen for research when the necessary arrangements are in place. Other than that Phase 2 will be very similar to Phase 1.

On Friday, however, the Taioseach announced that the Roadmap would be accelerated so that Phase 4, starting 20th July will, if all goes well, be the last, though measures will be in place for some time after that.

That’s good news of course but it’s all dependent on there being no second wave. As a cautionary tale, take a look at the numbers for Covid-19 Iran:

Iran has been experiencing a second wave of new cases for some time now, and this looks set to produce more cases than the first, but this has only recently resulted in an increase in daily mortality figures:

Note the lowest number of new cases per day in Iran was just under 1000. That’s far fewer than the United Kingdom, which has chosen to undo its restrictions far more rapidly in Ireland. The number of confirmed new cases in Ireland reported yesterday was just 24; in the United Kingdom the figure was 1557. In my opinion there is a strong possibility that the UK will follow a similar trajectory to Iran…

Welcome to Pride Month 2020!

Posted in Covid-19, LGBTQ+, Politics on June 1, 2020 by telescoper

Once again it’s time for a month of LGBTQ Pride.

Although the main Dublin Pride event has been cancelled this year because of the Covid-19 outbreak, there are still a number of virtual events going on.

Thus year more than any other Pride gives us an important opportunity to express solidarity to all grieving and fighting for a better world in the face of monstrous injustices such as the murder of George Floyd.

That includes those of us who are white and gay acknowledging that systematic racism exists and that by keeping quiet and doing nothing we are, however unintentionally, complicit in it.

Covid-19 in Ireland: the Pandemic’s Progress

Posted in Covid-19, Maynooth on May 29, 2020 by telescoper

I noticed last night when I was updated the numbers and graphs on my Covid-19 page that it is now 90 days since I started counting on 28th February. By way of an update here are the latest graphs (as of last night):

Mindful of a study that suggests that the general public do not understand log plots – I have had some angry messages on Twitter accusing me of deliberately misleading people by using a log axis – here are the daily updates on linear plots, first the record of new cases:

And second the recorded new deaths:

The latter appears rather noisy because of low numbers.

You may notice that these plots look a little different from those presented elsewhere (e.g. here). That is because I have treated the various retrospective corrections that have been made in a different way from others, generally by adjusting the cumulative totals but not the daily figure. For a full explanation of what I’ve done see the notes here. I also haven’t smoothed the data at all. Other representations tend to use a 7-day moving average to get rid of weekly artifacts of reporting, especially the “weekend effect” by which there appear to be fewer deaths on Saturday and Sunday.

If you don’t like log plots then you really won’t like this one, which is a plot of daily cases against the cumulative number on log-log axes:

I like this plot because I think the message is clear: it would give a straight line if the cases were growing exponentially, which was the case initially. You can see that both cases and deaths are well past this stage. In Ireland it seems the Covid-19 pandemic is under reasonably good control. According to the experts the value of the reproductive number R in Ireland is in the range 0.4 to 0.5, and it seems community transmission of the disease has almost stopped.

I haven’t left Maynooth since February so I’ve been here all through the lockdown. The overwhelming majority of people I’ve seen have been observing the restrictions. I can just think of just one occasion that was an exception, on the way into the local supermarket, when someone failed to observe the 2m social distancing when he pushed past me while I was washing my hands with the gel provided. When told by an assistant that he had to wait in line and wash his hands before coming in he refused and was then told to leave, which he eventually did after unleashing some foul language. He was obviously drunk, but probably a twat even when sober. Maynooth is a small and rather quiet place (especially when there are no students around, like now) and there may be worse issues elsewhere, but it does seem that Irish folk are behaving very sensibly.

For the record, as of last night there were 24,481 confirmed cases of Covid-19 in Ireland and 1,639 people have died. That means that the number of deaths per million of population is approximately 332. That’s a lot fewer per capita than the UK (officially 553, but probably more like 900) a lot larger than, say, Denmark (which is of a similar size) which is on 98 Covid-19 deaths per million population or Norway which is on 44. The reason for the large number despite the stricter lockdown than the United Kingdom, seems to have been the number of deaths in care homes.

On this basis I’d summarise the situation by saying that Ireland hasn’t done all that well when you look at it in the cold light of day, but it could have been a lot worse. Credit is due to the medical experts for their leadership.

Another thing worth mentioning is that according to the experts the fraction of the population that has been infected with Covid-19 is probably around one per cent and is very unlikely to exceed five percent. That means that if the infection begins to spread again then it will do so with very little resistance and the exponential phase we saw in March will recur.

So what next?

Ireland is currently in Phase 1 of a the Roadmap, a programme of gradual and justifiably reduction of the restrictions imposed to halt the spead of Covid-19. Phase 2 is supposed to begin on June 8th. However, next Monday (1st June) is a bank holiday and we have very good weather at the moment – it’s about 27 °C outside as I write this. That, together with the good news from the Covid-19 data may well convince some people to forget about the restrictions and start having barbecues, go to the beach, etc. There must be some concern that this may trigger a second wave, which will at best cause delays on the Roadmap and may require a second total shutdown.

There is a thoroughly reprehensible opinion piece in the Irish Times today by Stephen Collins that on the one hand deliberately encourages mass disobedience if the government “doesn’t move to ease the lockdown measures”. Bu the government has moved to ease the lockdown measures. Quite rightly, though, the movement is slow and cautious. People need to be patient and continue listening to the experts, not people like Stephen Collins.
