1/ Further thoughts on @DavidAFrench's important essay on #ChristianNationalism.

It's great to see a leading evangelical thinker publicly engaging the topic.

But....

COVID Masks: Mechanistic View: Part 2: Fine Aerosol Emissions:

Masks may increase fine aerosol emissions from: 1) nebulization of large droplets into fine aerosols, or 2) friability of certain mask materials creating "aerosolized fomites."

Please share:

Here are the studies:

The question is whether facemasks are actually a source for viral aerosols by:

1) Masks get saturated by large "respiratory droplets" containing viral molecules. Air turbulence against trapped droplets may create aerosols that eventually diffuse around edges. Continued...

Trapped droplets potentially get pushed through the filter media of the mask, getting nebulized into aerosols.

Particles don't always stay in the mask:

Study: Ha'eri 1980

Title: The efficacy of standard surgical face masks: an investigation using "tracer particles"

Albumin tracer particles put inside a surgical mask were dispersed into the room by breathing.

Viral molecules can get airborne from air turbulence.

Study: Liu 2020
Title: Aerodynamic analysis of SARS-CoV-2 in two Wuhan hospitals.
SARS-2-COV sub-micrometer aerosols not tightly bound to surfaces, get airborne when PPE is taken off.

We are all products of our own environments. Our environments shape our character, our personality, our habits, our identity.

The environment that Ousmane Dembélé grew up in and the environment that FC Barcelona seeks to engulf its youngsters with could not be more different.

The Great Gatsby starts with a life lesson.

"Whenever you feel like criticizing any one, just remember that all the people in this world haven't had the advantages that you've had."

Ousmane hasn’t had the advantages that La Masia youngsters have had. That’s why he’s Ousmane.

Like every La Masia youngster, Ousmane grew up with a dream: playing for Barça.

Like every youngster, he fought to stand out amid a talented group of players, the majority of which would fail to go pro.

However, his football education was the polar opposite to that of La Masia.

Ousmane did not reside in one of the most expensive academies in Europe: he lived in a low-cost public housing unit in Normandy. He did not play in the well-trimmed pitches of La Masia, he played in the concrete jungles of Évreux. These disadvantages made him the man he is today.

While street soccer encourages individuality & creative freedom, academy-based training like La Masia encourages unselfishness & teamwork.

That’s why Barça produce certain types of 20-year-olds like a factory line. It’s also why Barça spent €145m on a 20-year-old Ousmane.

women of twitter: raise your hand if you’ve ever discovered that a male colleague with the same (or less!) years of experience and same job title as you was actually making more money?

i’ll go first: 🙋🏽‍♀️

i’ll never forget the feelings i experience when i found this out. initially, i felt shock, followed immediately by self-loathing—it seemed like the company had gotten me “on the cheap” and it made me feel incredibly like i had been incredibly stupid to not negotiate for more.

that quickly evolved into rage: how did they think it was okay to meet his negotiation demands when he was hired but not think to look at the other people at the same level and wonder if their compensation should be raised to match his, too?

i had always thought that i had always been an excellent performer at every company and role that i’ve held, so finding this news out felt a bit humiliating; i had to fight feelings of self-doubt and push myself to remember that i am stellar and deserved better—i deserved equity.

this is the moment in my career where i fully realized that i had to be own fiercest advocate. that was the moment that i decided to never assume that the company would see your worth—instead, it was always going to be on me to MAKE them to see it, or to go somewhere that would.

For Black History Month, Vox is publishing a big series on rethinking policy for Black America.

I wrote 3,200 words on eradicating exclusionary zoning.

It's a 3 step formula: Persuade, incentivize, and if all else fails, SUE THE SUBURBS.

Thread

We know that exclusionary zoning is locking millions out of opportunity.

Work by @OppInsights, Richard Rothstein, Ta-Nehisi Coates, @nhannahjones, @RickKahlenberg, Chang-Tai Hsieh, Enrico Moretti and @ProfSchleich details the economic impact of these discriminatory policies.

51 years after the Fair Housing Act, it's never been seriously enforced. It's time to change that.

First things first, Biden has work to do to convince whoever can be convinced that there is a racial, environmental, and economic imperative to undo residential segregation.

Use whatever explanation works!

For sympathetic progressives Biden should link racial and environmental justice to ending exclusionary zoning.

For everyone else, he can simply make an economic

Second, there are many tools to incentivize localities that rely on federal dollars to reform their zoning codes.

There is a ton of federal money that can be conditioned on reforming exclusionary zoning laws. @ebwhamilton has some good ideas on this front.
