The Meaning of a COVID-19 Second Wave

I’ve been hearing the term “second wave” being used more and more frequently in connection with the COVID-19 crisis. For instance, in this article [1] about Singapore, Taiwan and Hong Kong facing a second wave of coronavirus cases from citizens returning from overseas. This seems faulty logic to me: it isn’t a second wave, it’s a continuation of the first wave relocating from a different geographical place. I don’t mean just to single out this article because numerous TV and radio newscasters, newspaper articles and websites worldwide are commonly using the same kind of wonky logic in connection with a so-called coronavirus second wave. When what they really mean is that the same source of the virus has either: (i)  lead to a continuation of cases from another location or (ii) made a reappearance after initial efforts for containment have only been partially successful.

Why do we describe resurgence in coronavirus cases in an inconsistent manner with the phrase “a second wave”? What has happened that we can’t agree on the meaning of a term that is so important to the coronavirus crisis?

My answer is after the page jump.

My Trip Down Memory Lane

Thinking about updating my curriculum vitae today, I was triggered to reminisce about my senior high-school experiences back in 1974-5. Amazing how sharply some memories came flooding back through the eyes of a 17-year-old. I remember about being part of the Science, Mathematics and Technology group of 4 that all shared dreams of becoming scientists, technologists or engineers: Wayne, Geoffery B,, Jon and myself. At the beginning of senior high, one of the Industrial Arts teachers had suggested that the 4 of us take a lower level of English so we could concentrate on Maths, Science and Industrial Arts. As you can imagine, the English Department was not at all impressed that some of their students were taking a level of English that demanded less than their full capabilities. What happened next is far from what you might expect (read the full story after the jump).

The Game of Thrones Finale!

There are spoilers ahead if you haven’t caught up with GOT season 8 episode 5 as yet.

I speculated about the (then) upcoming HBO Game of Thrones final season in a previous article. Turns out that I was right that episode 3 would contain the epic Battle for Winterfell against the Army of the Dead. I was wrong in that I didn’t predict that the Night King would be defeated and the threat from the north tied up in that same episode.

From my speculation, the other thing I did get right was that there would be treachery and betrayal from Varys and Tyrion. As Tyrion says: “thoughts aren’t treason” so he hasn’t, in his view, crossed the line yet. Though, after the apocalyptic-scale destruction of King’s Landing that Daenerys instigated in episode 5, it remains to be seen if Tyrion will continue to side with her.

Speculation About Game of Thrones Season 8

In my former life as an academic, I used to joke to my colleagues that Game of Thrones was essential reading as a standard operations manual for working in universities nowadays.

GOT as a manual for negotiating the world of research grants, where, figuratively, you either win the game or die and of navigating a path between the wheeling and dealing of the big-time professors, administrators, bean-counters, health and safety officers (hey, don’t underestimate their power). On many occasions, the internal and external politics between all of the players seemed to operate on a GOT-like scale. There were times I must admit that I felt no better than a denizen of the “Flea Bottom” in King’s Landing.

Given that internal politics in most organisations of more than a handful of people can feel a bit like GOT, from time-to-time, why not distract yourself with a little idle speculation about the upcoming Game of Thrones Season 8? I’m hoping to speculate on enough topics that I’ll be able to make a random hit and be able to say “I told you so!” The truth is that my speculation is unlikely to be any better than anyone else. But its fun isn’t it? [March 7: I’ve added new updates in notes at the end]

Update — Careful to Whom You Hand the Keys for Encryption

There was of course no way of knowing whether you were being watched at any given moment. How often, or on what system … It was even conceivable that they watched everybody all the time. George Orwell, Part 1, Chapter 1, in 1984

In an earlier post Careful to Whom You Hand the Keys for Encryption I described the extraordinary events of 6 Dec when the so-called “encryption busting” Access and Assistance Act passed into law on the last hours of the last sitting day of  Federal Parliament before the end of 2018.

It passed after the Labor Party opposition, who had been opposing the AA Bill (Shadow Attorney General Mark Dreyfuss described it as being “obviously dangerous”) gained a promise from the Government that amendments to the Bill would be considered when Parliament reconvened in February. Well that’s now and it occurred last week on the 13 and 14 Feb in a Bill introduced as the Telecommunications and Other Legislation Amendment (Miscellaneous Amendments) Bill 2019 [1].

The Unfairness of Measuring Teaching Performance – Revisited

A women of a minority group teaching at a whiteboard
A survey of student evaluations of teaching shows that men rate higher.

Last year I posted an article on The Unfairness of Measuring Teaching Performance concerning anonymous student comments that said that the teacher was “too old” [1]. An article published on the online site Phys.org [2] found that male teachers were most likely to be evaluated the highest by students and female teachers from a non-English background the lowest. Further, the bias showed up most in student surveys in Science and Business and was largely absent from students surveys from Engineering and other disciplines.

This study was based upon 500,000 student surveys of teaching at the University of NSW, Sydney between 2010 and 2016. It involved more than 3000 teachers over 2000 courses. across 5 Faculties.

In my previous article, I strongly supported teaching surveys as a tool for professional teacher development using tailored questions that are teacher selectable. It was my belief that problems arise because of

… the impersonal nature of the survey, as well as the fact that it is exclusively university, administered, that is the heart of the problem.

Burke and Wills Expedition — Forensic Analysis of the Death of Charlie Gray

Charlie Gray (? – 1861 ) is the forgotten man of the Burke and Wills Expedition of 1860-1. Burke and Wills are credited with the first crossing of Australia from south to north and then south to Cooper’s Creek [1] again. That they were accompanied by John King (1841 – 72) is commonly remembered because he was the only member of the crossing party to survive. Charlie Gray is often only remembered as a footnote: that he crossed the continent with Burke and Wills but died on the return from the Gulf of Carpentaria, the day that the crossing party spent burying his body, was instrumental in the tragedy that was to follow.

The death of Charlie Gray has attracted a good deal of controversy, as I’ll examine in this article.

It is my belief that this article is the first time that the events leading up to his death have been subjected to a detailed forensic scientific examination.

My conclusions show that the likely cause of Gray’s death was from a parasitic disease that compounded his generally poor health and malnutrition. Furthermore, this same parasitic disease affected the other members of the party, hastened their worsening malnutrition, leading indirectly to the deaths of Burke and Wills some months later. John King was also close to death but was fortunate in finding the native Yandruwandha people who showed him kindness and made him part of their tribe until the Victorian Relief Expedition was able to rescue him.

Andy Weir — My Geek Hero

 
Do I just sit back and allow a portrayal of events that, claim to be scientifically factual, to be made to be made into a feature movie, when I know, and can show by basic chemistry and toxicology, that the events portrayed are wrong?

If you’ve followed The Dossier you may have read the article: “Artemis” by Andy Weir — Blame it on the Moon. At the time I wrote this I was concerned that “Artemis” the movie might be in the pipeline. Andy has impeccable connections in this regard after having his earlier book The Martian made into a movie, directed by one of the most celebrated directors around in Ridley Scott.

For these reasons, I shouldn’t have been surprised that a feature film adaption has been in the works since even before the book itself was published according to Wikipedia.  Since I wrote my article, I had been struggling with the thought: what is my responsibility? Do I just sit back and allow a portrayal of events that, claim to be scientifically factual, to be made into a feature movie, when I know, and can show by basic chemistry and toxicology, that the events portrayed are wrong? Furthermore, the depicted events could mislead the public if made into a feature-length movie. Being a former science academic (who still considers himself to be in the STEM education business) these things matter to me.

Menindee Lakes Fish Kill

Fish Kill at Lake Menindee 7 Jan 2019.
Fish Kill at Menindee Lakes. 7 January 2019 by Debbie Newell.

The fish kills on the Darling River and at Menindee Lakes in Western NSW have been getting a lot of media attention and feelings are running hot within Australia and overseas. Politicians, both NSW State and Federal, have been running for cover, blaming the severe drought, rather than water mismanagement.

While I’d like to lambast politicians for their failings, in this case, it’s not going to achieve much. The problems with the Darling River are already so serious that political failings are becoming our responsibilities; once the consequences and recovery costs flow through the economy. There’s not the time for a blame game. As things stand, we can’t rely on our leaders to work for the health of the Murray-Darling Basin without bringing public pressure to bear. Lack of action on a leadership level calls out for more grass-roots action. However, being able to exert public pressure requires an educated cross-section of the public with a consensus direction on what needs to be done.

For the above public educational reasons, I’m requesting support for the development of a Fishkill 2 learning module which is based upon Fishkill that ran successfully with 1st-year Natural Resource Science students at the Queensland University of Technology  (QUT) for nearly a decade (2000-8). Fishkill 2 needs to be developed from the now antiquated original Fishkill as a community-based project, using new source material, an accessible online format and an expansion of the learning modules and scenarios to include lessons gained from the Menindee Lakes Fishkill.

Support Fish Kill ver. 2 Citizen Science Project

Help me fundraise to support a community version of the Fish Kill online eLearning Module that is sleek, modern and independently-sourced (suggested: multiples of $25).

The Dossier: Highlights 2018

When I started writing the Dossier at the end of July, I was still dealing with issues around job loss and finding a new direction. I wrote about some of this in the article: Job Loss and Sense of Purpose, getting that off my chest was a positive step forward for me. I’d like to thank Jo Stanley for her kind reply: my post was a response to a newspaper article that she had written about similar events in her own life.

I started to gain some sense of purpose which I wrote about with An Epiphany or Two, of Sorts which is primarily an appeal for online learning systems to be more personalised. The observation was that the area of online learning is dominated by institutionally-centralised learning management systems (LMSs) that suit a formal learning setting but aren’t necessarily well-suited to more personal and decentralised learning. In August requested support to get such a project off the ground This request is reproduced again below.
