First class today and I brought up new #chatGPT policy. Sharing in case others find helpful.
Background: for one assignment students create a two-page summary for the public on a #HealthyBuildings topic.
🧵
2/ Answer basic questions: what is it? Why it matters for health? What are solutions. Topics can be anything (asbestos, VOCs, nano materials, green cleaners, SARS-CoV-2…)
3/ aside: Why only 2 pages? b/c it’s *hard* to write concisely for the public. It’s easy to spew out 5 pages.
4/ so, the problem should be obvious - chatGPT can do this assignment on seconds. So, here’s my policy:
1. Students can use chatGPT (it’s a tool they’ll use going forward, so they should learn how to use it well is my opinion)
5/
2. Students have to disclose if they use it (not dinged in any way if they use; not dinged if they don’t)
6/
3. Students are responsible for the accuracy of what they submit 4. Students are responsible for the citations (that they match and support the claim and are good/reliable sources)
7/
5. Students are responsible for plagiarism, including citations of “derivative works”, even if (when) chatGPT does not know it’s own sourcing

Absolutely critical and not discussed enough. The failure of ASHRAE - *the* standard setting body for ventilation - to set a ventilation target during the pandemic for a respiratory virus that spreads entirely indoors in under ventilated spaces.
For those who do not know, ASHRAE did have a group working on this. Excellent scientists. They produced a ventilation target last year. Never saw the light of day. Why?
Some in my own field like to throw daggers every which way - WHO, CDC, frontline public health officials - but have not looked inward at the failings of our own field. Many have close ties to ASHRAE and that might be the reason. This is holding us back.
--> SARS- CoV-2 and other respiratory pathogens transmit through inhalation exposure indoors, mostly in places with inadequate ventilation and filtration
--> Current building standards promote bare-minimum ventilation and filtration targets
That's why our @Lancet@Commissioncovid Task Force on Safe Work/School/Travel wrote this report, which proposes better ventilation and filtration targets
Theme emerging from users across different disciplines. It used to be easy/quick to find good info on Twitter - you opened the app and it was there. THAT was its value and utility. Now, it takes a lot more searching (and time) to find what you need, if you find it at all anymore
The silicone wristbands we use in this study act as passive air quality samplers, constantly absorbing chemicals in the air around us. Then we put those wristbands into hormone assays...
--> Every wristband extract was **hormonally active**
In our prior work, we did something similar, but with dust, and found that dust is **hormonally active**. This study shows that indoor air is, too. This shouldn't surprise anyone, based on what we know about the potential for chemicals in products to leach out into the indoor env
There are SOLUTIONS! Harvard is doing this, led by @H_Henriksen1 and @GreenHarvard. Demanding disclosure of what's in products we buy, and telling the market we don't want products w/ certain classes of chemicals. seas.harvard.edu/news/2021/03/s…
"We cannot continue to subject kids to the 2020 playbook as adults go out and do whatever they want. And, remember, parents who don’t feel comfortable can always have their children wear high-grade masks." cbsnews.com/boston/news/bo…
Boston Public Schools made investments in ventilation/filtration (5,000 air cleaners), and is one of only a few districts in country actively monitoring CO2
So bizarre to me how one-way masking got attacked…
