The ventilators used for severe cases of COVID run at much higher pressures.

Ingroup biases (race, class, religion) don't really become a factor until the outgroup is assertive. I saw this firsthand as a foreigner in Korea. The first few years I kept my head down and was treated well. "He's just like a Korean." As I became more confident at work, my coworkers started playing politics to hold me back. (One of them used race explicitly to form a coalition.) Nowdays I don't play politics, and my performance is good, but I still get a lot of comments about my "attitude" from my boss. Nevermind that people I don't report to directly love working with me.

To fix the problem of capitalism, you would have to fix the problem of pricing (=efficient allocation of) goods into supply chains, which problem grows as the fourth power of the number of goods available.

It's probably better to keep making our current system more transparent and work for prices to better reflect society's values than to "exit capitalism".

Afaik, for nonimmigrant visas they don't care about skills, but they do care about any ideological background (preventing terrorism) and they care a lot about the probability of overstaying the visa: they want to see evdence of connections and plans to return from the US.

Could you quantify the number of poor Americans who do not have access to clean water in the US, and provide some support to the idea that it is due to racism?

My understanding is that the Flint situation is due to mismanagement, which was done after a certain political party created laws to remove elected leadership from indebted municipalities (most of the indebted municipalities were controlled by the opposing party).

Which is to say that the Flint situation got a lot of press because it was rare, and that the motivations were likely political rather than racial. As such, in isolation it is not good evidence for your arguement. It would be appreciated if you could provide some statistcs.

That is a useful system for middle readers with limited volcabulary to jump into high school / professional reading, but not so good for very early readers. Note how all the grecoroman stems are defined in terms of germanic words, which are phonetic.

The article is concerned with students who find words like "rabbit" challenging, not with students figuring out "neologism".

You're right, and one would hope that happened. But not knowing the field or journal norms, all I could do was search the text for "Bonferroni" and "regist". In my lab if additional analysis was requested by the reviewer and we did it, we would have added a sentence to the manuscript.

But not having published in this field or journal, I have no idea what their norms are.

The previous thread was very critical of this article's statistics.

Reposting my comment:

When I see a headline like this my instinct is to jump to "overfitting". In a study like this they use P=0.05 as their cut off for significance. One in 20 such studies would be expected to give meaningless results. But they had the choice of cohort (all kids or boys and girls separately), so 1 in 10. They measured urine concentrations of fluorine at three time points during pregnancy, which makes for 7 different potential combinations of input variables, for a total of 14 different potential analyses, where 1 in 20 is expected to be significant. Of course, they didn't preregister, so who knows whether their analysis changed on the fly..

That's an interesting point, but I was confused for about 15 seconds. Maybe it's because I studied Korean instead of Spanish.

Ordinary people occasionally need to be knocked back into seeing what they will lose if they keep up their present course of action. Life is full of temptations, most people are not very self reflective, and people naturally push boundaries.

In particular, textual flirting with the opposite sex is something that is easy to fall into, starting innocently and delivering a strong dopamine hit with each correspondence. The dopamine-addled S.O. can easily rationalize to themselves that they are just writing, that their privacy is suddenly Very Important, it's not cheating, and surely that's not innuendo! ("When we finally meet for coffee we'll just be friends.")

The well-delivered ultimatum, although blunt, makes the situation clear and leaves no room for rationalization: the emotions associated with the proto-affair are inappropriate to an exclusive relationship.

I've had to make this ultimatum twice. 50% of the time it has resulted in the recipient suddenly becoming self-aware and making an effort to change her behavior. As a result, I'm quite certain the current S.O. is not BPD.

Presumably a lot of domestic Chinese goods require materials from abroad to produce. Remember that until a few years ago China had to import the tips for ballpoint pens.

In English the word is forest fires.

Ultimatums are one of the best tools for people in terrible relationships to use:

"Give up the bottle, or I leave."

"Stop hitting the kids, or I call the cops."

(Other ultimatums, such as "Marry me or I kill the dog" are obviously abusive.)

In this case, the woman is forcing the man into a choice, but he still has a choice. "Show me that I'm not wasting my time or I leave" is in the grand scheme of things quite tame.
