Brief thread to debunk the repeated claims we hear about transmission not happening 'within school walls', infection in school children being 'a reflection of infection from the community', and 'primary school children less likely to get infected and contribute to transmission'.

I've heard a lot of scientists claim these three - including most recently the chief advisor to the CDC, where the claim that most transmission doesn't happen within the walls of schools. There is strong evidence to rebut this claim. Let's look at


Let's look at the trends of infection in different age groups in England first- as reported by the ONS. Being a random survey of infection in the community, this doesn't suffer from the biases of symptom-based testing, particularly important in children who are often asymptomatic

A few things to note:
1. The infection rates among primary & secondary school children closely follow school openings, closures & levels of attendance. E.g. We see a dip in infections following Oct half-term, followed by a rise after school reopening.


We see steep drops in both primary & secondary school groups after end of term (18th December), but these drops plateau out in primary school children, where attendance has been >20% after re-opening in January (by contrast with 2ndary schools where this is ~5%).
@danielashby @AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd I'll bite. Let's try to keep it factual. There's a reasonable basis to some aspects of this question, that it might be possible to agree on. Then there are other, more variable, elements which depend on external factors such as transport and energy policy. /1

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd First up, we know reasonably well how much energy it takes to propel a high-speed train along the HS2 route. We can translate that into effective CO2 generated by making some assumptions about how green the electricity grid is. /2

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd Secondly, we have a reasonable grasp of how much CO2 is going to be generated by building HS2 - there are standard methods of working this out, based on the amount of steel, concrete, earthmoving, machine-fuelling etc required. /3

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd Thirdly, we can estimate how much CO2 is generated by cutting down trees, and how much is captured by planting new trees. We can also estimate how much CO2 is needed to keep the railway running and generated by maintaining the track /4

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd We know how much CO2 is saved by moving goods by freight train on the lines freed up by moving the express trains on to HS2, rather than by truck. /5
Hi @officestudents @EHRC @EHRCChair @KishwerFalkner @RJHilsenrath @trussliz @GEOgovuk

The Equality and Diversity section of your job application has 'gender' in what appears to be a list of the protected characteristics under the Equality Act 2010.

However...

1/15


However, 'gender' is not a protected characteristic under the Equality Act 2010 and is not defined in the Act.

Sex is the protected characteristic under the Act, but that is not on your list.

2/15


You then ask for the 'gender' of the applicant with options:

Male
Female.

3/15


Again, 'gender' is not a protected characteristic under the Equality Act 2010 and is not defined in the Act.

4/15


Sex is the protected characteristic and the only two possible options for sex are 'Female' and 'Male' as defined in the Act and consistent with biology, but you don't ask for that.

'Gender' is not a synonym for sex.

1/ A thread of comments & observations about the death of the cackling vampire Rush Limbaugh.

My first observations in the main thread are here, but this offshoot is needed because there's been so many wise & witty things I've


2/ First, re: those who in their wayward moral obtuseness feel we "can't speak ill of the dead." I've said that this is what abuse enablers say, but I hear that some religious traditions preach this. Oy.
So there's this: https://t.co/7Ky4RA3nkZ &


3/ Drucker is another great wit, and this carries the proper mood


4/ There's definitely a Jewish Tradition angle for how to treat evil people who die: the only respect is to justice, right & wrong, and above all compassion's existence necessitates condemning cruelty


5/ We're coming up on #Purim, and that's all about how to remember evil. There may be a reason, then, that I share the attitude of many other people committed to righting
