1/9 - “In the second wave we acquired much more evidence that schoolchildren are almost equally, if not more infected by SARS-CoV-2 than others.”

2/9 - “The problem is not that schools are unsafe for children,” Mr. Boris Johnson said last week. “The problem is schools may nonetheless act as vectors for transmission, causing the virus to spread between households.”

3/9 - “An antibody survey conducted by researchers in Geneva in May and December, using thousands of random samples, found that children of age 6 to 18 were getting infected as often as young adults. The study has yet to be peer reviewed.”

4/9 - “One reason for this: The Swiss city’s schools have been open since the summer, while restrictions have been placed on adults, meaning schoolchildren played a bigger role in transmitting the virus during the autumn surge.”

5/9 - “In Austria, a nationwide survey by universities and medical institutes found that children under 10 showed a similar rate of infection to those between 11 and 14, and that the children in general were getting infected as often as teachers.”

6/9 - “Scientists also point to data from the U.K. which conducts a weekly random survey of the population. Just before the Christmas break, when schools were still open, the positivity rate among children was higher than in most adult groups, especially in those older than 11.”

7/9-“In Germany, researchers found that a majority of some 40 cases at a school in Hamburg in Sept were likely linked to a single person,which some scientists say highlights the risk of schools becoming #COVID19 clusters. Still, many policy makers in Europe say schools are safe.”

8/9 - “In France, which managed to curb infections while keeping schools open, PM Jean Castex ordered a nationwide 6 p.m. curfew but said it was a fundamental goal to keep schools open. FR is now imposing stricter rules for school canteens, and stepping up testing in schools.”

9/9 - “Austria, one of the first European countries to shut schools in November, plans to reopen them gradually from Jan. 25, but in staggered systems and with millions of test kits distributed to reduce the risk of infection.”

LIST OF QUESTIONS FOR MPS
From @ClareCraigPath and Dr Jonathan Engler:
.
1.Why are SARS-CoV-2 antibody levels flat or dropping across all age groups since May if the pandemic is still going?

2.What percentage of the population is assumed to have had prior immunity to SARS-CoV-2 in the SAGE forecasting models?

3.Why do 50% of household members not catch SARS-CoV-2 from infected persons with whom they live?

4.Why have Japan and South Korea not had any serious outbreak if the human species has no prior immunity to SARS-CoV-2?

5.What percentage of the population of the UK is assumed to be immune to COVID-19 (including prior immunity) as of this date?

As my Christmas present to you all, here is a list of my top-10 metal tunes of 2020, in no particular order. It's a mixed bag of genres and styles, but they're all bangers!

First up, The Terror Begins by Make Them Die Slowly. Horror-movie inspired grind/black/industrial from Mick Kenney and Duncan Wilkins.

Next, Northern Irish thrashers @gamabomb, with Lords of the Hellfire Club from their excellent new album Sea Savage.

Now for something a bit off the beaten track: brilliant New York black metal experimentalists @imperialnyc's City

Time for something a bit more accessible: this year's best symphonic metal from Sweden's @eleine. Here's the title track from the fantastic 'Dancing in Hell' album.

On teaching without grades.
A long-ish (20-tweet) 🧵. Here goes.

So, you know how you write lots of comments on an essay/exam, and the student looks at the grade and never reads the comments? That's because when grades enter the picture, the learning stops. /1

Instead of focusing on learning, there is a lot of negotiation: can we find one or two points on the midterm as the student is just on the verge of A-?

Everyone is just on the verge of the next grade.

And all the evals are not about the class but about the grading. Really? /2

Is the grade at all informative? If you are just below the A- or just above that, is that giving the student any information about how to improve their knowledge or skills? No. t is just a useless, demoralizing & stressful smoke screen /3

Students' abilities, challenges, and learning are multidimensional. Providing feedback on these many dimensions is much more useful for promoting growth and learning than are quantized unidimensional grades. /3.5

There is an alternative: do away with grades. Keep the feedback -- lots of it (this is not less work for us teachers) but never summarize it in a unidimensional uninformative number (unless you absolutely have to). /4

This open letter created a false dichotomy in the schools debate, pitting MH against safety. Thread..

@theAliceRoberts @MaryBoustedNEU @ReicherStephen @SusanMichie @alansteinoxford

We are saddened that the signatories of the letter do not appear to have channelled their energy into encouraging innovation in distance learning and support which could serve to bolster children's mental health in order to limit some of harms caused by isolation.

That the potential for the Internet to be used as a "fantastic communications tool" and provide "a creative and visual style of learning" affording "a positive and interactive experience" as identified by @ProfTanya in the Byron Review has not been celebrated is a travesty.

The report identified the internet to be a platform for children and young people to "express themselves and keep in touch" and is "a fantastic place to meet people and find support, friendship and

When we consider that internet based interventions such as iCBT are now well established psychological practice, it is a great sadness that the expertise of professionals in this field has not been channelled toward helping craft a recovery curriculum children desperately need

I've been serving on grad admissions committees at MIT for 5 years - in EECS and Media Lab

If you want to get into a PhD at a place like MIT, here's a thread with some advice based on my observations

1/13

1. Grades do matter, especially in courses that are important for your chosen field

2. Research matters, even more than grades

3. Publications matter, but letters of recommendation matter even more

4. Your statement of purpose should be the cherry on top of the cake

2/13

When I say grades matter, it doesn't mean that you need 100/100 or A+ in every course. It does mean that you are expected to have strong competence (close to straight A/A+/A-) in technical courses relevant to your field of interest

3/13

While grades show competence, a PhD is about research. So, the more your application demonstrates research potential, the higher your chances for acceptance. It's not about the number of papers (if any), but about the quality of research you pursue

4/13

This is why the best evaluation of research potential often comes from letters of recommendation (LoRs)

Letters shed light on technical competence, creativity, work ethic, & personal interaction. All of which are important for a successful PhD

MUST READ TILL END:
FB POST BY MR PRABEER BASU,
IAS-1976(BIHAR)
" Received a hurtful post from an old friend and colleague. He was on my daily Broadcast list of WhatsApp. He requested that I do not send him any of my posts on 'political' issues. I gave him a long explaination
>2

2/29
on why I write and what I write. But he was not convinced.

Being alerted by him thus, I felt I should clarify to all who read my posts on what exactly I think and do.

The charge against me is that I wrongly support our current Prime Minister, Shri Narendra Modi..
>3

3/29
and that it establishes I am not rational and impartial anymore.
Let me try and explain.First and foremost,I do not write on 'political' issues. I write on 'national' issues. For example, I have no opinion on whether Rahul Gandhi should be President of his party or not.
>4

4/29

Similarly, I have no views whether BJP is a better party than Congress or vice versa.
Even after 36 years in the IAS I have no MLA, MP or anyone involved in politics whom I can classify as my friend or even acquaintance.
>5

5/29
So, naturally I don't care which party wins or loses as long as the winning party runs an honest government doing good to my nation.
Now, why I speak in favour of Shri Modi:

1. Ever since the beginning of my service I realised that Planning Commission was not serving..

#ஆதித்தியஹ்ருதயம் ஸ்தோத்திரம்
இது சூரிய குலத்தில் உதித்த இராமபிரானுக்கு தமிழ் முனிவர் அகத்தியர் உபதேசித்ததாக வால்மீகி இராமாயணத்தில் வருகிறது. ஆதித்ய ஹ்ருதயத்தைத் தினமும் ஓதினால் பெரும் பயன் பெறலாம் என மகான்களும் ஞானிகளும் காலம் காலமாகக் கூறி வருகின்றனர். ராம-ராவண யுத்தத்தை

தேவர்களுடன் சேர்ந்து பார்க்க வந்திருந்த அகத்தியர், அப்போது போரினால் களைத்து, கவலையுடன் காணப்பட்ட ராமபிரானை அணுகி, மனிதர்களிலேயே சிறந்தவனான ராமா போரில் எந்த மந்திரத்தைப் பாராயணம் செய்தால் எல்லா பகைவர்களையும் வெல்ல முடியுமோ அந்த ரகசிய மந்திரத்தை, வேதத்தில் சொல்லப்பட்டுள்ளதை உனக்கு

நான் உபதேசிக்கிறேன், கேள் என்று கூறி உபதேசித்தார். முதல் இரு சுலோகங்கள் சூழ்நிலையை விவரிக்கின்றன. மூன்றாவது சுலோகம் அகத்தியர் இராமபிரானை விளித்துக் கூறுவதாக அமைந்திருக்கிறது. நான்காவது சுலோகம் முதல் முப்பதாம் சுலோகம் வரை ஆதித்ய ஹ்ருதயம் என்னும் நூல். முப்பத்தி ஒன்றாம் சுலோகம்

இந்தத் துதியால் மகிழ்ந்த சூரியன் இராமனை வாழ்த்துவதைக் கூறுவதாக அமைந்திருக்கிறது.
ஐந்தாவது ஸ்லோகம்:
ஸர்வ மங்கள் மாங்கல்யம் ஸர்வ பாப ப்ரநாசனம்
சிந்தா சோக ப்ரசமனம் ஆயுர் வர்த்தனம் உத்தமம்
பொருள்: இந்த அதித்ய ஹ்ருதயம் என்ற துதி மங்களங்களில் சிறந்தது, பாவங்களையும் கவலைகளையும்

குழப்பங்களையும் நீக்குவது, வாழ்நாளை நீட்டிப்பது, மிகவும் சிறந்தது. இதயத்தில் வசிக்கும் பகவானுடைய அனுக்ரகத்தை அளிப்பதாகும்.
முழு ஸ்லோக லிங்க் பொருளுடன் இங்கே உள்ளது https://t.co/Q3qm1TfPmk
சூரியன் உலக இயக்கத்திற்கு மிக முக்கியமானவர். சூரிய சக்தியால்தான் ஜீவராசிகள், பயிர்கள்

👇 Thread. New deck getting published this week: "Consumer startups are awesome, and here's what I'm looking to invest in at Andreessen Horowitz." If you want to read it, subscribe to my newsletter here: https://t.co/262t8eh0wf

1/ A lot of new consumer technologies have been introduced to US households in the last 100 years. But it's taken many of them - like the telephone - more than 50 years to get to the majority of the US. Why is that?

2/ We had to literally teach people how to use phone. Which end goes to your mouth, which goes to your ear. Say "hello" when people call. The motivation of consumers to talk to their friends has always been there, but we had to teach the behavior

3/ If you compare phones to the latest technologies, there's been a huge shift. Things are being picked up much faster.

4/ Even while there's been all this innovation recently, physically speaking, we are still the same human beings from 100,000 years ago.
