Our preprint on the impact of reopening schools on reproduction number in England is now available online: https://t.co/CpfUGzAJ2S. With @Jarvis_Stats @amyg225 @kerrylmwong @KevinvZandvoort @sbfnk + John Edmunds. NOT YET PEER REVIEWED. 1/

We used contact survey data collected by CoMix (https://t.co/ezbCIOgRa1) to quantify differences in contact patterns during November (Schools open) and January (Schools closed) 'Lockdown periods'. NOT YET PEER REVIEWED 2/

We combined this analysis with estimates of susceptibility and infectiousness of children relative to adults from literature. We also inferred relative susceptibility by fitting R estimates from CoMix to EpiForecasts estimates(https://t.co/6lUM2wK0bn). NOT YET PEER REVIEWED 3/

We estimated that reopening all schools would increase R by between 20% to 90% whereas reopening primary or secondary schools alone would increase R by 10% to 40%, depending on the infectiousness/susceptibility profile we used. NOT YET PEER REVIEWED 4/

Assuming a current R of 0.8 (in line with Govt. estimates: https://t.co/ZZhCe79zC4). Reopening all schools would increase R to between 1.0 and 1.5 and reopening either primary or secondary schools would increase R to between 0.9 and 1.2. NOT YET PEER REVIEWED 5/

Our results suggest that reopening schools is likely to increase R to above or close to 1.0, under which conditions we would expect cases to stop falling and begin to increase. NOT YET PEER REVIEWED 6/

Note that we assume that upon reopening, schools operate as in November. If schools were to implement additional measures to reduce transmission in schools (e.g. mask wearing, regular testing, ventilation) the impact on R may be smaller. NOT YET PEER REVIEWED 7/

We urge that these results should be considered alongside other evidence on the impact of school closures on transmission. Always read the limitations section first. NOT YET PEER REVIEWED 8/

Finally, we are clear that allowing children to return to classrooms as quickly and safely as possible is a public health priority. These results need to be considered alongside the clear benefits that reopening schools will have on children and wider society 9/

Hi teachers and parents 👋 I have complied a short list of useful online maths tools and virtual manipulatives to assist you with distance learning. I have included the curriculum area and suggested what class group they would be most suitable for. See below! #mathschat #edchatie

This website allows you to create a graph. Useful for 5th/6th class. Children can create pie charts, bar charts, etc. adding in their own data and designing and labelling the X and Y axis themselves. Charts are easily

Online protractor. Useful for 5th/6th class. The teacher can use screen sharing to how to use a protractor. Children who do not have a protractor at home can use this to measure angles.

Exploring area and perimeter. Useful for 4th - 6th class. Tasks can be set to create shapes of a specific area/perimeter. There is also a game that can be used for formative

Interactive geo-board. Useful for 1st - 6th class for exploring perimeter and area and the characteristics of shapes. Images can be saved easily to be shared with the teacher via email, screen share etc.

@MattHancock says yet again that “Schools are safe”, because children are at low risk of serious disease.
With current v high disease prevalence (maybe 1 in 20 or 30 in #London ,#1in50 elsewhere) MORE children will catch #coronavirus & MORE children will become very ill. 1/8🧵

In itself that’s not good. There are some v sick kids around the country right now & because they often present differently they may not be diagnosed so quickly. Often with gastrointestinal & joint symptoms & odd rashes. Parents & educators may not be aware of this. 2/8

Families, especially those in large multigenerational or BAME households are already at increased risk of severe #COVID19.
#Teachers & #earlyyears staff in JAN 21 STILL have virtually no #PPE. There will be many over 50s & others who are CV/CEV. This is not good. 3/8

The families of <18s are at increased risk. We know that.
I’ll keep showing this 👇because Gvmt keep ignoring it.
And the lack of adequate & appropriate #PPE puts all staff in these settings AND their families at increased risk.
This is not good. 4/8

So the “Schools are safe” mantra which is repeated over & over again can ONLY be based on the risk to children of severe disease VS the risk of them missing school.
NOTHING OR NO ONE ELSE.
In the midst of a deadly pandemic this is as bizarre as it is callous & ignorant. 5/8

New from me:

I’m launching my Forecasting For SEO course next month.

It’s everything I’ve learned, tried and tested about SEO forecasting.

The course: https://t.co/bovuIns9OZ

Following along 👇

Why forecasting?

Last year I launched https://t.co/I6osuvrGAK to provide reliable forecasts to SEO teams.

It went crazy.

I also noticed an appetite for learning more about forecasting and reached out on Twitter to gauge interest:

The interest encouraged me to make a start...

I’ve also been inspired by what others are doing: @tom_hirst, @dvassallo and @azarchick 👏👏

And their guts to be build so openly in public.

So here goes it...

In the last 2 years I’ve only written 3 blog posts on my site.

- Probabilistic thinking in SEO
- Rethinking technical SEO audits
- How to deliver better SEO strategies.

I only write when I feel like I’ve got something to say.

With forecasting, I’ve got something to say. 💭

There are mixed feelings about forecasting in the SEO industry.

Uncertainty is everywhere. Algorithm updates impacting rankings, economic challenges impacting demand.

It’s difficult. 😩

I get asked a lot how you can improve your skills and chances of getting a job as a developer. Best way is to work on a real-world project, deploy it, make it open-source, get feedback from others, share your knowledge, rinse, repeat.

Here are my top 7 project ideas. Thread 👇

1. 📊 Build an embeddable user feedback form (clone of https://t.co/xFHvT7iFEf) . Have a top notch design, fully working, minimal bugs, open-source, deploy it free on Heroku / Netlify / Vercel. If you can spare $11, buy a domain. Share with the whole world when done.

2. 🚀 Build a product roadmap SAAS.(https://t.co/Rq9DBeCMlh) Users can create new projects, create different stages for their projects. The community can submit project ideas, vote on existing ideas. Project owners pay a monthly fee per project.

3. ⛈️ Build a digital marketplace. (https://t.co/BWd1aeWMt5) Sellers can upload digital products for sale. Customers can purchase digital products and securely download. Sellers are paid out at the end of every month. Don't make it complicated, implement a great design.

4. 👨‍🏭 Build a job board software (https://t.co/EjWoMyqi9H). Companies can post jobs for a price, providing a link to the job application form. Jobs can be highlighted as urgent for an additional price.

School is an astonishing failure of modern society.

We're taught about dinosaurs before learning how to function as people.

Thread: Life lessons I wish school taught all of us.

Schools don't teach us to:

• Think critically
• Nurture curiosity
• Save and prep taxes
• Sustain relationships
• Have difficult convos
• Navigate mental health

Yet they teach how to:

• Differentiate dinosaurs
• Memorize the periodic table
• Make paper snowflakes

Why is school curriculum so broken?

1. Awareness: Those in power don't realize how bad it is.

2. Priorities: It's not a pressing issue. Voters care about the cost of education—not enough about WHAT is taught.

3. What to do: Shout to the politicians and educators in power.

Onto the lessons I wish I was taught.

These are the ones on my mind lately. This list could be 1,000 items long. Add yours to the thread.

Here we go.

Many relationship troubles emerge from one root cause:

Assuming bad intent.

One of the highest ROI things we can teach our children:

Start by assuming good intent: Train your reflex to ask questions before making assumptions.

Always lead with curiosity—never critique.

Beautiful Story of Guruvayurappan

Poonathanam Namboothiri was a great devotee of Guruvayurappan. One day Poonthanam was going to Guruvayur Kshetram. It was night time and eventhough Namboothiri was tired he continued to walk

Suddenly some thieves came and blocked his way. Poonthanam cried for Shri Krishna to help. Thieves snatched all valuables from him, but Namboothiri holding his Bhaghavatam book called Shri Krishna to help. That time a man came in a horse back and fought with thieves and protected

Namboothiri. Poonthanam thanked Krishna for helping him from danger and said to the man that "Shri Krishna has send you here and I don't know how to thank you". The man smiled and told that he is Mangattachan, minister of samoodhiris. Poonthanam once again thanked him and

gave his ring to Mangattachan as a token of thanks and continued his journey. He reached Guruvayur early morning for Nirmalya Darshan. Temple poojari came near him and told that Guruvayurappan came in his dreams and asked to hand over the ring to poonthanam.

When he opened Kshetra Nada poonthanam was surprised to see his ring on Guruvayurappan, which he gifted to Mangattachan. He understood that it was Guruvayurappan who came as Mangattachan to protect him. This is how Bhagwan treat his devotees.

TRUMP: "I've decided to eat babies."

PEOPLE: "He can't eat babies, that's super illegal."

TRUMP, on TV, eating babies, not even cooking them first: "People are saying that I really am the best baby-eater, folks."

NYT: "Trump Vs. Babies: The Rhetoric On Both Sides Must Stop"

Jeff Flake tweets: "It is a sad day in America when this callous man can eat babies live on TV"

Jeff Flake, 10 seconds later, votes to help him install a series of 4,000 new judges that are very, very pro-babyphagia.

Judge Kavanaugh, found drunk in a Capitol Hill closet: "I LIKE BEER. OKAY? I LIKE BEER AND I LIKE BABIES AND THAT'S NOT SO WRONG. THAT'S RIGHT. I LIKE BABIES DIPPED IN BEER. I JUST DIP EM. IN THE BEER. THE BABIES. THE BABIES I EAT. OKAY? THAT'S AMERICA."

Mike Pence, wringing his hands about the baby-eating: "We must take care of our children. Our youngest must be protected on this troubling day."

Mike Pence then invites a Baby Chef to say a prayer.

Twitter Users: "It's a distraction technique! Trump eating babies is trying to DISTRACT YOU from ALL THE OTHER HORRORS, which are themselves distractions from the BABY-EATING. It's DISTRACTIONS ALL THE WAY DOWN."

Trump: *eats tons of babies at a rally*

*literal tons of babies*

अस्य श्री गायत्री ध्यान श्लोक:
(gAyatri dhyAna shlOka)
• This shloka to meditate personified form of वेदमाता गायत्री was given by Bhagwaan Brahma to Sage yAgnavalkya (याज्ञवल्क्य).

• 14th shloka of गायत्री कवचम् which is taken from वशिष्ठ संहिता, goes as follows..

• मुक्ता-विद्रुम-हेम-नील धवलच्छायैर्मुखस्त्रीक्षणै:।
muktA vidruma hEma nIla dhavalachhAyaiH mukhaistrlkShaNaiH.

• युक्तामिन्दुकला-निबद्धमुकुटां तत्वार्थवर्णात्मिकाम्॥
yuktAmindukalA nibaddha makutAm tatvArtha varNAtmikam.

• गायत्रीं वरदाभयाङ्कुश कशां शुभ्रं कपालं गदाम्।

• These are the elements of SPACE, FIRE, WIND, EARTH & WATER.

• All these five faces shine with three eyes 'त्रिक्षणै:'.

Again sharing bank nifty intraday weekly straddle. How to play by selling straddle.
Mostly will work on Monday to Wednesday. Sometimes on Friday.
Why to pay your money to learn this if u can get it here.
U need only practice.
Let’s go.

Say bank nifty future is at 32000.
Sell both 32000 call and put.
Considering current volatile market lest say premium on Monday morning is 350 on both sides.
Sold with 700 points combine premium.
If bank nifty will trade in narrow range say +\- 100 hold it.
If moving 200 points

then exit previous sold straddle. Sell new one. Let’s say BN moved +200
Now sell 32200. If bank nifty will move here within range then u will get profit through theta decay. Follow same procedure for next 150-200 pts move.

This is only for single straddle sell position.

Now in second case sell three straddle. 31900/32000/32100
In case of 100 points move no need to change.
If 200 + then future is 32200.
Exit 31900 and sell 31200 straddle.
If moving another 100 then exit 32000 and sell 32300. Continue same with 100 points move.
If no move then

it will consolidate between 32000-32200 or 32100 to 32300 and u will get theta decay.

This is for normal move. Sudden big move may come anytime. So keep SL in system.
If u r selling at 350-350 then keep SL in system 475 for both legs.
Practice it. No need to attend webinar.
