"If you have a forest of barriers in a classroom, it’s going to interfere with proper ventilation of that room... Everybody’s aerosols are going to be trapped and stuck there..."
"... and building up, and they will end up spreading beyond your own desk.... One way to think about plastic barriers is that they are good for blocking things like spitballs but ineffective for things like cigarette smoke. The smoke simply drifts around them, so they will give the person on the other side a little more time before being exposed to the smoke. Meanwhile, people on the same side with the smoker will be exposed to more smoke, since the barriers trap it on that side until it has a chance to mix throughout the space."

I came across an article mentioning Dr. Marr back last November, where she made the point that you can use a CO2 detector to monitor the freshness of indoor air and bought one immediately and have been using ever since. Why the public health people don't talk more about ventilation baffles me. Just opening a window can help and costs nothing. Here's a blog post I did on the subject. https://registeredmusictherapist.blogspot.com/2021/03/reducing-covid-risk-with-co2-detector.html
I am gobsmacked. Somebody finally noticed the screaming obvious.
I KNOW! A dastardly plot by the plexiglass industry.
"Those Anti-Covid Plastic Barriers Probably Don’t Help and May Make Things Worse"
It's just one example of "experts" getting it wrong, while arrogantly pushing counterproductive policies in the name of "science."
Of course, the panic of 2020 helps to account for a lot of useless, or worse than useless, things.
Removing stupid barriers is one thing; real accountability for the stupidity, and the arrogance, another.
Among the commenters here John Henry or I could have told them that. Maybe others. It’s almost like they didn’t consult anyone who does HVAC for a living.
But hey, now a professor has spoken up! And since she’s a female, people have to take her seriously!
Tell the US Postal Service. The absurd barriers at the Post Office make it almost impossible to hear the masked staff. the black weights at the bottom holding the screen in place obscure the writing surface at the counter. In addition the weights holding down the screen block your vision when trying to enter info into the credit/debit machine. Of course there is a big sign that says "Please do not touch screen", but you have to grab and move it to make a transaction with the clerk. It made me want to go 'Postal'.
This just in from the “No Shit, Sherlock” committee of top government men…
Top people working on this!
Now explain the effectiveness of surgical masks.....
Virtually everything public health officials have said since this all began is wrong (or at least unsupported by any decent research) except:
Stay home if you’re sick
Wash your hands and don’t rub your eyes
—Public health researcher
Buried the lede.
This paragraph is found at the end of that article:
Aerosol scientists say schools and workplaces should focus on encouraging workers and eligible students to be vaccinated, improving ventilation, adding HEPA air filtering machines when needed and imposing mask requirements — all of which are proven ways to reduce virus transmission.
Transmission of COVID-19 virus by droplets and aerosols: A critical review on the unresolved dichotomy
The practice of social distancing and wearing masks has been popular worldwide in combating the contraction of COVID-19. Undeniably, although such practices help control the COVID-19 pandemic to a greater extent, the complete control of virus-laden droplet and aerosol transmission by such practices is poorly understood. This review paper intends to outline the literature concerning the transmission of virus-laden droplets and aerosols in different environmental settings and demonstrates the behavior of droplets and aerosols resulted from a cough-jet of an infected person in various confined spaces. The case studies that have come out in different countries have, with prima facie evidence, manifested that the airborne transmission plays a profound role in contracting susceptible hosts.
[ ... ]
Droplet transmission occurs by the direct spray of large droplets onto conjunctiva or mucous membranes of a susceptible host when an infected patient sneezes, talks, or coughs. In the meantime, direct physical touch between an infected individual and susceptible host and indirect contact with infectious secretions on fomites can cause the contact transmission.

If I was a clerk dealing with a public that walks in, sniffling, sneezing and coughing, to buy some stamps or a cup of coffee, I'd feel much safer with a plexi-barrier no matter how annoying it was. And as for a room full of sniffling third graders ...
In the (so far) 17-month Battle of the Experts, I have noticed that, until this article, only one kind of "expert" has been winning. Only one kind of expert has been quoted in the NYT and The Atlantic and MSNBC, etc. The only kind of expert that has been promoted or lauded or been allowed to fashion public policy has been the kind that recommends less freedom of movement, less communication, less autonomy in matters of health-- less of everything. Conversely, the experts who have been offering (often quite calmly and rationally) any kind of opposing views have been demonized as crackpots, yahoos, fascists, and "grifters." And anyone who might believe anything they say have been portrayed as MAGA-hat-wearing, Fox News-watching, vaccine-denying dingbats.
What do you make of that?
The people labeled as "fascists" aren't. It's the people mandating masks or vaccination that are the fascists. After all, the core concept of fascism is "mandatory unity" or "obey or else."
Our illustrious King Jay I of Washington is mandating indoor masking starting Monday. The appliance salesman I talked to yesterday wasn't happy having to wear the mask for 8 hours a day. They'll obey because they don't want to be fined. A case of "obey or else" fascism.
It is a trivial exercise to find online images of our rulers, who are mandating masks for their subjects, not wearing them themselves. If this "pandemic" was as serious as they make it out to be, they wouldn't be risking their lives going maskless at their birthday and dinner parties, would they?
Now do masks- they don't stop aerosols either.
We are rule by morons like Chuck above- Chuck is typical of any government employee we see today- as dumb as shit.
typingtalker,
And as for a room full of sniffling third graders ...
Ah, yes. Sure, let us teach; hey, we want to teach! Just keep us well away from those filthy, verminous third-graders. Preferably a couple of miles distant.
OK, so maybe some of us have already had COVID, and anyway Puerto Rico isn't really a hot spot. Not really.
Sorry. I'm married to a public school teacher, who got vaccinated as soon as he had the chance. Kids are no threat at all to the rest of you silly people. Suck it up, already.

Now, about those plexi barriers ...
Was on the beltline yesterday and saw an AA guy driving a pickup piled higher than seems possible with bicycles..no apparent securing mechanism, wearing a $.15 blue paper mask.

It looks right now that Barack Obama’s 60th Birthday party was a Superspreader Event, while Sturgis, again, was probably not.
