1/OK, I should really write another thread about university-centric regional development, because I think people often make some (very understandable) mistakes when thinking about this issue.

2/The biggest myth, I think, is that universities help regions by educating locals as undergraduates.

Skeptics of universities say: "But most of the people who graduate end up leaving."
3/In fact, most of what a university does for a regional economy is NOT about educating local kids.

Educating local kids is good for the nation, but doesn't help a region much.

The way a university helps a region is through RESEARCH.

4/Undergraduates usually leave town after graduation.

But university RESEARCH pulls in OTHER smart people from other regions, and they stay there.

Here's a paper showing that this is the main way universities increase a region's human capital: https://t.co/ofu256tsFi
5/Research also pulls in business investment.

Companies want to partner with university labs, so they can commercialize the technologies the labs produce. So they invest in the labs, and sometimes they even put their offices in the town.
6/So should we be worried that college enrollment is dropping?
https://t.co/NiVzQVgn5I

Answer: A little bit. But mainly because this means less tuition money that can be used to fund university research labs.
7/Yes, it would be great if universities were allowed to admit more foreign students (who pay high tuition that can be used to fund research labs that draw in smart workers and business investment).

BUT, the most important thing is to fund research more!!
8/Myth #2 is the idea that a university only helps a region if it creates a new technology cluster - a "next Silicon Valley".

Critics of university-centric development like to point out that the probability of succeeding at this is very low.

But this doesn't really matter.
9/Universities help regions even when they don't become the "next Silicon Valley".

My hometown of College Station is no Silicon Valley. But College Station, and its surrounding region, are thriving thanks to a university.

10/Even a humble, non-prestigious university can help a declining region in real, important ways.

Beyond the research-and-investment thing I discussed earlier, universities also draw in residents from small towns, creating pleasant small cities.
https://t.co/2xqpKdMZUs
11/And even if a town doesn't become a tech cluster, universities can help local business, government, and nonprofit leaders plan local industrial development.

https://t.co/hYSbEKxeV8
12/Finally, Myth #3 is the idea that university-centric development needs prestigious universities like Harvard to build new branch campuses.

In fact, this is unlikely to be a useful approach. https://t.co/uxUcLHzmON
13/We already HAVE tons of universities and colleges in almost all regions of America.

What we have to do is UPGRADE the RESEARCH CAPABILITIES of the second- and third-tier universities.
14/How do we upgrade existing 2nd- and 3rd-tier universities?

1. By spending more research dollars there

2. By encouraging companies to partner with the labs there

3. By letting these universities admit more high-paying foreign students

4. A new land grant program?
15/To sum up, the three big myths of university-centric development are:

1. The myth that education is the main thing universities do for a town

2. The myth that universities need to create the "next Silicon Valley"

3. The myth that new branch campuses are the answer
16/University-centric regional development is about research. It's about drawing in businesses. It's about drawing in people and creating a pleasant, efficient city in a declining region. It's about coordinating leadership to boost local growth.

And it works.

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%).

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.

Legacy site *downloads* ~630 KB CSS per theme and writing direction.

6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices

https://t.co/qyl4Bt1i5x


PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.

735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices

The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.

The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
