Fifth Covid Booster

Posted in Biographical, Covid-19 with tags , , on October 30, 2025 by telescoper

Just for the record, today I had my 5th Covid-19 vaccination booster. As an Old, I get prompted by the HSE to get free Covid-19 boosters and winter ‘flu jabs so I booked an appointment at a local pharmacist as I did last year. In fact I went into work this morning to say farewell to newly-doctored Aoibhinn Gallagher, and walked to the pharmacy afterwards. I didn’t have to wait long and the vaccination itself only took a matter of minutes.

That makes seven Covid-19 jabs altogether for me: the initial vaccination was in two stages, and I have since had five boosters. All but one of these have been Pfizer; the other was Moderna.

On previous occasions of this type I’ve usually managed to arrange an afternoon free afterwards in case of any adverse reactions. That was easy this time because it is Study Week at Maynooth University so there are no lectures. I did feel a bit tired after the jab, and had a short nap this afternoon. I also seem to have developed a runny nose, which may or may not be a reaction to the injection, but I don’t think it’s very serious.

Update: 24 hours on, I’m still feeling the after-effects. Hopefully, I’ll be better by the weekend.

That Magic Gene…

Posted in Biographical, Covid-19, History, LGBTQ+ with tags , , , , on September 25, 2025 by telescoper

While writing yesterday’s post about the evolution of languages, and the importance of genetic information in reconstructing the story thereof, I was reminded of a post I wrote a while ago about the peculiarities of my own genome, a listing of which I have on a CD-ROM at home. There’s not as much data involved as you might think: it’s effectively only about 800 MB.

Anyway, to cut a long story short, it turns out that I have the CCR5-Δ32 genetic mutation. Not only that, I have it twice over, in that I have two copies (homozygotes). I must therefore have inherited it from both parents. This mutation confers virtually complete immunity from HIV-1 infection.

The above graphic shows that more than 10% of the population in Northern Europe has this mutation in just one allele (i.e. they are heterozygotic). To get an estimate of how many have the form on two alleles (i.e. homozygotic) form you can just square that number, so around 1% or more.

It is thought that the CCR5-Δ32 mutation occurred in a single individual in Scandinavia around 1,000 years ago. When I wrote that post I tacitly assumed that it had propagated passively, i.e. without any particular selection, to the modern era. That it reached 10% of the population starting from just one individual surprised me, but I let it pass.

More recently, I came across a paper about how advances in genetics have impacted epidemiological studies. In the abstract it shows that my assumption was probably incorrect.

Algorithms of molecular evolutionary theory suggested that the CCR5-Δ32 mutation occurred but once in the last millennium and rose by strong selective pressure relatively recently to a ~10% allele frequency in Europeans. 

It goes on to say this:

Several lines of evidence support the hypothesis that CCR5-Δ32 was selected due to its protective influence to resist Yersinia pestis, the agent of the Black Death/bubonic plague of the 14th century.

I didn’t mention in yesterday’s post that evidence of the plague bacillus is found in a significant number of prehistoric human remains and this almost certainly played a role in the ebb and flow of populations. In the context of CCR5-∆32, however it seems that it may have been advantageous to carry it long before the arrival of HIV/AIDS. That might account for it reaching the relatively high level that it did.

Among the downsides, however, as the article explains, are an increased risk for encephalomyelitis and death when infected with the West Nile virus. Hopefully further cohort studies of people with this mutation will help elucidate its effect on other diseases.

By the way, in contrast to most people I know, I have still never had Covid-19…

Five Years at Home in Maynooth

Posted in Biographical, Covid-19, Maynooth with tags , , , , on August 26, 2025 by telescoper

I’ve received a number of bills and renewal notices of various kinds over the last few weeks, indicating the anniversary of me completing the purchase of, and moving into, my house in Maynooth. In fact it was five years ago today that I wrote a blog post occasioned by the fact that I’d collected the keys to this property, though it wasn’t until the following weekend that I actually stayed overnight here for the first time.

I was very lucky to be able to able to buy this property in what turned out to be a short window in the Covid-19 lockdown restrictions in the Summer of 2020. There were plans to return to on-campus teaching in September with drastic restrictions on the number of students in each venue. That plan was subsequently changed and then changed again to move almost all teaching back online, and then again to move again into a “Level 5” lockdown.

I was Head of Department back then. My memories of that time were immense levels of stress and frustration, constantly having to change our teaching arrangements with very little support from the University as well as shouldering a full teaching load. In order for the institution to carry on functioning, all teaching and support staff to do huge amounts of unpaid overtime while the institution built up a massive financial surplus. I could say more about the callous indifference to staff and students alike shown at that time by one particular member of The Management, but I think I had better save it for when I’ve retired.

Given the enormous workload I had then, it was to be almost another year before I had time to collect most of my belongings from my house in Cardiff and longer still before I managed to sell it and pay off the mortgage I took out to buy my house here. All this was much more complicated than I expected when I moved to Ireland!

Anyway, many of the things I’d planned to do when I moved here still aren’t done. I bought some old furniture from the previous owner with the intention of replacing it with new, for example, but I somehow never got round to that. Nor have I replaced the old windows, gutters, etc, yet…

One thing I have done is change the refuse collection. When I moved in I took over a contract with  Bord na Móna (literally “The Turf Board”), a company set up in 1946 to supply peat as a form of fuel but now diversified into other activities such as collecting and disposing waste. Over the last year the service provided by this company has degenerated to the point of complete unreliability. When I looked around for a replacement I found that Bord na Móna was also significantly more expensive than its competitors. Earlier this summer, therefore, I swtiched to a company called Greyhound which so far seems much better organized and is about 2/3 the price. That meant I had two sets of wheelie bins cluttering up my garden for about two months until Bord na Móna got around to removing theirs.

Pandemic Memories, Five Years On

Posted in Biographical, Covid-19, Education, Maynooth with tags , , , on March 13, 2025 by telescoper

At the start of my Computational Physics lecture at 9am this morning I suddenly remembered that it was the corresponding day five years ago that Covid-19 pandemic restrictions were introduced in Ireland. The date for that was Thursday March 12th 2020, while today is Thursday March 13th 2025, but it was the same stage of of the semester, the Thursday before St Patrick’s Day and the mid-term Study Break.

One thing I remember quite well from that day five years ago was that I told my Computational Physics class to keep an eye on their email during the day as I thought an announcement would be made. When it came – around lunchtime, if memory serves – it was much stricter than I had anticipated: from 6pm that day, all schools, colleges and cultural institutions were to close until 29th March. Few people believed that would be the end of it, and we were right!

I had a computing laboratory session that afternoon, which went ahead, but some students understandably left early as they had to find their way home. The next time I interacted with any students it was online, and remote working carried on for many months, not just the two weeks originally planned. I did not envisage it would last so long. Nor did I imagine how little support teaching staff would receive from management. Indeed, the University saw the opportunity to build up large surpluses during the lockdown, all generated by the huge amount of extra, unacknowledged and unrenumerated, work put in by academics and support staff. That’s all money that should have been spent on the education of students. It was never going to be easy to teach during lockdown, but deliberately withholding resources made it far harder than it had to be.

Among other things, the Covid-19 pandemic restrictions played havoc with my perception of the passage of time and messed with my memory. I remember some things very clearly, such the lecture and lab on the day the restrictions were announced, which seem like they happened a few weeks ago never mind five years. Other things are like ancient history. Several major life events took place during the Covid-19 period 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 for distorting one’s perception of the passage of time and powers of recall.

It was not just the disruption to routine of course. There was also a genuine fear of becoming infected. From time to time after my last in-person class on March 12th 2020, 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 never reached me, though I think even those of us who were never infected by Covid-19 were definitely affected by it.

Lecture Recordings Again

Posted in Cardiff, Covid-19, Education, Maynooth with tags , , , , , on March 5, 2025 by telescoper

Long before the pandemic restrictions – was it really five years ago that all that started? – I posted an item about an innovation I encountered when I moved to Sussex in 2013, namely lecture capture facilities which

…allow lecturers to record videos of their own lectures which are then made available for students to view online. This is of course very beneficial for students with special learning requirements, but in the spirit of inclusive teaching I think it’s good that all students can access such material. Some faculty were apparently a little nervous that having recordings of lectures available online would result in falling attendances at lectures, but in fact the evidence indicates precisely the opposite effect. Students find the recorded version adds quite a lot of value to the “live” event by allowing them to clarify things they might not have not noted down clearly.

A few years later, when I did some teaching back in Cardiff, I discovered that lecture recording had become normal practice there too. The main difference was that Sussex had a proper policy on important matters such as who could see the recordings, and what they could be used for, which allayed some staff fears about snooping and the inhibition of academic freedon; the policy at Cardiff had not been fully developed in advance of the rollout of lecture capture, which I think was a big mistake.

Anyway, before the pandemic we didn’t really have any facilities at Maynooth University for recording lectures so it certainly wasn’t normal practice. With the onset of Covid-19 lecture recordings and live streams became the only way to carry out teaching and we lecturers made the best of what we had at home. A couple of years ago, after restrictions were lifted, I posted about a meeting between student representatives and staff in the (then) Department of Theoretical Physics during which students criticized, among other examples of inadequate teaching resources. Part of the reason for this is the drastic shortage of student accommodation which means many students have to commute long distances to campus and have difficulty doing that every day for lectures.

I – and I’m speaking personally here – wish we could offer lecture recordings as routine. Unfortunately, however, and much to my disappointment, Senior Management at Maynooth University has discouraged lecture recording as a matter of policy and has not invested in the technology required to enable it, so it is not practicable anyway.

In my view the benefits of lecture capture far outweigh the disadvantages, and we should incorporate recordings of lectures as part of our standard teaching provision, as a supplement to learning rather than to replace face-to-face sessions. Every student learns in a different way and we should therefore be doing as much as we possibly can to provide a diverse range of teaching resources so that each can find the combination that suits them best. Technology allows us to do this far better now than in the past.

Some really enjoy live in-person lecture sessions, especially the ability to interact with the lecturer and the shared experience with other students, but others don’t like them as much. Others have reasons (such as disability) for not being able to attend in-person lectures, so providing recordings can help them. Others still have difficulty attending all lectures because of a dratic shortage of student accommodation. Why not in any case provide recordings for everyone? That seems to me to be a more inclusive approach.

The problem with lecture capture in Maynooth is that we will need to improve the cameras and recording equipment in the large lecture rooms to make it possible for lectures with a significant mathematical content. The existing setups in teaching rooms do not easily allow the lecturer to record material on a whiteboard or blackboard. In Cardiff, for example, the larger rooms had more than one camera, usually one on the lectern and one on the screen or whiteboard (which has to be placed further away and therefore needs to be of higher resolution). In Maynooth we only have small low-resolution cameras in the teaching rooms. In fact I have far better facilities in my study at home – provided at my own expense – than my employer is prepared to provide on campus.

Anyway, the reason for mentioning all this is that I saw an article today in the University Times (a student newspaper based at Trinity College, Dublin). I can only infer that someone at Trinity has floated the idea of mandatory lecture recordings, because the piece argues against them even with

…established guidelines for their use, re-use, storage, and dissemination, and a ban of their use during industrial action.

I think a properly negotiated agreement with the Trade Union representing staff (e.g. IFUT, of which I am a member) covering these points would allow me to accept mandatory lecture recordings. Worries about covert monitoring or unauthorized dissemination on social media would hopefully be assuaged by such an agreement. A particular issue in the UK, given the current meltdown of its higher education sector, Senior Management may sack lecturers to save money but keep using their recordings. That would be unconscionable, but that doesn’t mean it won’t be tried.

Fourth Covid Booster

Posted in Biographical, Covid-19 with tags , , on December 3, 2024 by telescoper

Just for the record, today I had my 4th Covid-19 vaccination booster. As an Old, I get prompted by the HSE to get free Covid-19 boosters and winter ‘flu jabs so I booked an appointment at a local pharmacist, which is how they are done these days, which is much better than traipsing to City West or Punchestown. In fact I went into work this morning, and walked to the pharmacy and back. I didn’t have to wait long and the vaccination itself only took a matter of minutes.

The vaccination record is not as fancy as the one I got last year for my third booster last year, but it will have to do as a souvenir:

That makes six Covid-19 jabs altogether for me: the initial vaccination was in two stages, and I have since had four boosters. All but one of these have been Pfizer; the other was Moderna.

On previous occasions of this type I’ve always managed to arrange an afternoon free afterwards in case of any adverse reactions. Today, however, I went straight from the pharmacist to get a quick lunch and then had a two-hour lecture with the Engineers, which I survived. Once again, there are no serious ill-effects, apart from a slight discomfort at the injection site and a general feeling of tiredness. I think I’ll sleep well tonight!

P.S. Last night, as I usually do, I checked my calendar before I went to bed to make sure I was ready for all the items on the following day’s agenda, including the Covid-19 jab. When I slept, for some reason I had a funny dream that I had invented a new form of vaccine that could be administered via a cigarette!

Leaving Certificate Results

Posted in Bad Statistics, Covid-19, Education, Maynooth with tags , , , , , , on August 23, 2024 by telescoper

Today’s the day that over 60,000 school students across Ireland are receiving their Leaving Certificate Results. As always there will be joy for some, and disappointment for others. The headline news relating to these results is that a majority (68%) of grades have been scaled up to that the distribution matches last year’s outcomes. This has meant an uplift of marks by about 7.5% on average, with the biggest changes happening at the lower levels of grade.

This artificial boost is a consequence of the generous adjustments made during the pandemic and apparent wish by the Education Minister, Norma Foley, to ensure that this year’s students are treated “fairly” compared to last year’s. Of course this argument could be made for continuing to inflate grades next year too, and the year after that. Perhaps the Minister’s plan seems to be to keep the grades high until after the next General Election, after which it will be someone else’s job to treat students “unfairly”. Anyway, you might say that marks have been scaled to maintain a Norma Distribution…

One can’t blame the students, of course, but one of the effects of this scaling is that students will be coming into third-level education with grades that imply a greater level of achievement than they actually have reached. This is a particular problem with a subject like physics where we really need students to be comfortable with certain aspects of mathematics before they start their course. It has been clear that even students with very good grades at Higher level have considerable gaps in their knowledge. This looks set to continue, and we will just have to deal with it. This issue was compounded for a while because Leaving Certificate grades were produced so late that first-year students had to start university a week late, giving less time for the remedial teaching that many of them needed. At least this year we won’t have that problem, so can plan some activities early on in the new Semester.

Anyway, out of interest – probably mine rather than yours – I delved into the statistics of Leaving Certificate results going back six years for Mathematics (at Higher A and Ordinary B) level, Physics and Applied Mathematics which I fished out of the general numbers given here.

Here are the results in a table, with the columns denoting the grade (1=high) and the numbers are percentages:

You can seen that the percentage of students getting H1 in Mathematics has increased a bit to 12.6% after falling considerably from 18.1% in 2022 to 11.2% last year (2023); note the huge increase in H1 from 2020 to 2021 (8.6% to 15.1%). Another thing worth noting is that both Physics and Applied Mathematics have declined significantly in popularity since 2019 from 7210.

Now that the results are out there will be a busy time until next Wednesday (28th) when the CAO first round offers go out. That is when those students wanting to go to university find out if they made the grades and university departments find out how many new students (if any) they will have to teach in September.

P.S. When I was a little kid we used to call a “Certificate” a “Stiff Ticket”. I just thought you would like to know that.

Back to A-level Again

Posted in Cardiff, Covid-19, Education with tags , , , on August 16, 2024 by telescoper

Yesterday was the day that students in United Kingdom received this year’s A-level results. It seems the number of students getting the highest grades went up in England but down in Wales and Northern Ireland. That difference could be because of the timing of the transition from Covid-19 adjustments, with marks in Wales and Northern Ireland only returning to pre-pandemic levels this year; this may disadvantage applicants to universities this year, of course.

Another thing worth mentioning is that the number of students taking Physics A-level has increased by 12% this year, reversing a recent downward trend. In Physics, 31.5 per cent of students achieved the top grades. This was an increase from last year when 30.8 per cent were awarded an A or A*. That probably means that most students who applied to do Physics at university will get a place in their first-choice institution.

As always my advice to students who got disappointing results is

There’s always the clearing system and there’s every chance you can find a place somewhere good. If you’re reading this blog you might be interested in Physics and/or Astronomy so I’ll just mention that both Cardiff and Sussex have places in clearing and both are excellent choices.

At least you’ve got your results; students here in Ireland will have to wait next Friday (23rd August) to get to get theirs – not in the form of GCE A-levels, of course, but the School Leaving Certificate. I have been away all year so don’t know how admissions have been going for Maynooth but the intention seems to be to increase student numbers in any way possible despite the already huge student-staff ratio (the highest in Ireland) and lack of student accommodation. Anyway, Covid-19 adjustments are still in place in Ireland so the artificial inflation of Leaving Certificate grades will continue. It seems the Government doesn’t know how to get out of the system it has locked itself into and is intent on leaving it for the next Government to sort out.

Have you never contracted Covid-19?

Posted in Biographical, Covid-19 with tags , on August 9, 2024 by telescoper

I’ve taken the liberty of reblogging this post from a blog that I follow, as it is a question that interests me. As far as I know I have never contracted Covid-19, but I think I’m a rare case. I know many people who have had it multiple times. The most I think is five. There was an outbreak at the Euclid Meeting in Rome too, which affected over sixty people. I am hearing through the grapevine that case numbers are rather high at the moment, both in Europe and the USA, but in the absence of any systematic testing it is difficult to know the precise situation.

A couple of months ago I had a nasty cough which I thought might have been Covid-19 but repeated tests came back negative.

In the interest of full disclosure, I am fully vaccinated and boosted. I suppose another booster will be available in the autumn and I’ll take that too.

Anyway, I’d be interested to hear through the comments from anyone who has never had Covid-19 if you feel like divulging such information.

The Cause of Academic Anomie

Posted in Covid-19, Education, Maynooth with tags , , , on July 22, 2024 by telescoper

I thought I’d share a paper entitled Academic anomie: implications of the ‘great resignation’ for leadership in post-COVID higher education, which presents a new study of 167 academics who quit UK academia, finding they often blame the declining quality of academic management. The abstract is here:

The full paper can be found here (Open Access). In case you weren’t aware the word anomie according to Durkheim, being a state of “normlessness”, in general means the lack of social cohesion and solidarity that often accompanies rapid social change. I’d say there’s a lot of that about these days.

The study relates directly to UK universities, many of which are struggling and some of which are on the verge of collapse as a result of several factors, not just those stemming from the Covid-19 pandemic. One of the surprising (and depressing) things about Ireland is that the people in charge of third level education here seem to be determined to repeat here the terrible decisions being taken across the Irish sea despite all the evidence of the damage they have done in the UK. Many of the comments made by individuals mentioned in the paper will definitely resonate with colleagues in Maynooth.

This bit particularly caught my eye:

All too often dangerous managers simply skip from one university to the next causing havoc wherever they go. (RS2 – Male, former Senior Lecturer, pre-1992 institution)

Tell me about it!
