kaitai··on Time to bring back asylums?
A shelter is generally a place that you go to overnight, where you can't keep your stuff, you have to be out early in the morning and come back at a strict time in the afternoon or evening. Very different than an asylum which provides 24 hour care. Also, there are many homeless families (shelters don't serve them that well), but when it comes to mental illness it's not usually a family thing.

Nah, this is a lot of projection. More likely fanfic: could be that the one who got tenure had the former advisor who would add her to grants and bring in a lot of $$, or who started a center that would bring in a lot of $$.

Routine research often is easier to get through funding committees and get published. Less "what journal does this fit in, I'm not sure our division should fund this, does the PI truly have the expertise needed to do research in this, this result doesn't clearly advance the field"

For heaven's sake, think a little. This is an empirical discussion of hiring heuristics that result in a certain system. It's not just networking (generally used to refer to development of professional connections, though yes people use it to refer to smoking weed together or engaging in the same sport) and the poster didn't say nepotism either. It is certainly favoritism (hiring people you already know and like without necessarily casting a wider net) and it's clear that there are structural effects from it that develop on gender and race lines (you're in the men's hockey team together, you're in a fraternity or sorority, you're in an ethnic club).

What sriram_sun said is entirely factual, and a lot of us get left out of the networks for various reasons. That's also just factual. The fact that folks here are all "oh you're just jealous, you're calling it nepotism" -- nah, it's just facts, and there is no need to get emotional about it. There is nothing inherently wrong about hiring people you know -- like any move in a game, it has knock-on effects. If you'd like to help broaden networks, just do it. And for those who feel defensive about it, consider the phrase "hit dogs holler".

Do you understand what it takes to get tenure in the US? Generally 10 years post PhD of grinding, working summers and weekends. (That's from 3 years of postdocs and 7 before tenure.) By the time you get tenure you don't know how to not work through the summer, and you have graduate students who need to be supervised (they'll be doing a substantial portion of their research over the summer and you need them to get through). You'll have grant funding for summer research (because if you don't, you didn't get tenure) and you'll need to ensure that the work you've promised to the granting agency gets done in some form or another, not least so that you can get the renewal or extension of the grant, which is needed to pay the graduate students. You'll have some conferences that will require travel, and you'll need to get things done with your collaborator before she goes on sabbatical and your other collaborator before he becomes dean of students. You'll have a revise and resubmit or three, and you'll be trying to finish another article before the August 1 submission deadline for the special journal edition (yes it'll be pushed back but if you let it slide, the grad student working on it will start teaching mid-August and then progress will slow to a crawl and you'll really run into trouble, that student is supposed to be transitioning to another project as well due to a grant you have starting at the beginning of the academic year).

Heck, I have been out of academia 4 years now and I still have minor revisions to a paper complete in the next week!

kaitai··on Children of alumni no longer have admissions edge at Carnegie Mellon, Pitt
Now let's back up a moment. In US society we have said for the last 60 years max that it's usually illegitimate to discriminate on the basis of race, and before that it was legal and actually approved of to discriminate on the basis of race. Discrimination on basis of race is written into the founding documents of the land. That's what makes it the one of the deepest fractures in our society, the fact that it was legislated for the vast majority of the time the colonies and then country have existed.

It's also worth acknowledging that elite social clubs have always had the ability to pick who they want -- the pretty people, the rich people, the well-connected people. Given that racism is suddenly (last 60 years) less popular/legal than it used to be in the US, is it any wonder that the elite social club of Harvard wanted to pick the most attractive candidates coming from groups previously denied admission? Now the end of "affirmative action" says that Harvard can no longer curate the class it wants to have its favored racial mix. Since this end of affirmative action is a direct strike at Harvard's ability to pick its elite the way it wants to, how do we continue to justify legacy status, again? "You can't pick people with the experiences you want; you just have to pick rich kids/according to heredity, that's the only fair way to do things." Really? Why?

America hasn't always hated racism, but it has always hated a hereditary nobility.

kaitai··on Refusing to teach kids math will not improve equity
You are on to something here. The thing I'd contribute is that then we need teacher training to improve math teaching in the US. Math teaching in the US is often of poor quality, as teachers may not be trained well and are often not confident in their own mathematical ability. Curricula are often haphazard.

The US generally takes the approach that changing the curriculum or changing standards will change outcomes, but rarely invests in teacher quality, which would have very high impact (compare to Korea, Finland, etc.).

kaitai··on Refusing to teach kids math will not improve equity
Thanks for folks pointing out the link to the article on Dallas -- I'll post it here to boost it. https://www.the74million.org/article/dallas-isds-opt-out-pol...

25 years ago I was part of my National Honor Society outreach committee. One of the things I and my committee co-chair did was go to all the "normal" (rather than IB) classes and tell students that with a good GPA they could join NHS (as NHS did have a demographic makeup that wasn't reflective of the school). Students had no idea. The outreach did make a difference. The Dallas experiment, and the tutoring discussion in the article, resonate deeply with my later experiences as a math prof as well. Pushing kids results in higher achievement.

kaitai··on Refusing to teach kids math will not improve equity
Disagree for a number of reasons.

1) A good public education should be available to all students, with reasonable transportation provided. This is an axiom for me.

2) Private schools do not seem consistently provide a better education, but they do enable siphoning and segregation of students. Students with disabilities of various types can be excluded; the education can be explicitly religious; private education can really enable exclusivity of many kinds. On one level all that is fine -- but I don't want taxpayer dollars to support it. Raise money thru your church to send kids to that stuff.

In addition, I think your premise is false. In the school district I live in, children can apply to attend any school in the district. Charter schools are available as well as public schools. Choice is available with a publicly funded model, and as a parent I am partaking in that and switching a kid from a high-scoring school that I'm nevertheless not fully satisfied with to another high-performing school that rivals the privates for about $30k less a year.

But in the end, I actually don't think competition forces improvement. The misalignment of incentives is too great. Individual teachers want to do their best for their kids, in general, and they also want to improve their income. To do their best, they try to help the visible high achievers if they can but they absolutely must take time on the kids acting out. Administrators have to deal with district edicts and teacher demands, but they don't have the money to support teacher development (which would be the #1 thing to help both teachers and kids). School districts/boards need to show they're "using technology" and "being equitable" and "being innovative" and all sorts of stuff that is not the same as improving outcomes. Everyone is supposed to do well on the tests, even when the tests are stupid (and whoo-hoo are some of them terrible). Schools have to deal with homelessness and hunger, because no other regional agency deals with all the kids in the area. Nothing lines up and so we end up with free lunch that's not so nutritious but does hit a calorie bar, attempts at equity without supports (putting kids with behavioral problems into crowded and understaffed classrooms), a bunch of teachers who are scared of math yet have to teach it, who would benefit most from upgrading their skills....

kaitai··on Never waste a midlife crisis
"I think the crux of the midlife crisis is coming to terms with tradeoffs. Everyone has spent potential to get where they are, and there aren't do-overs." << This. It is at the same time crisis-inducing and very motivating, depending on your situation and personality. You look down the pike and think "If I have an average lifespan, I can kick this shit into gear and have the whole timespan I've already lived to get some stuff done" or you think "I only have (x) years left, it's too late already." But either way, the crux of the matter is that you have a limited set of choices left. You had a limited set of choices before, too, but young people don't realize that. They don't quite feel the chapters being ripped out of the book of life yet, they don't see the just-pruned branches falling from the tree of life... Every affirmative choice you make is also a choice that kills something else. And this is not bad, necessarily -- a well-pruned fruit tree yields more fruit, without breaking. But it's not how we've been raised. We've been raised with limitlessness. We have not been raised with the interior disciplines of pruning and weeding and culling.
kaitai··on Instant Messenger History: Lessons for the Threads Era of Social Media

kaitai··on FDA approves first nonprescription daily oral contraceptive
I think that it's really shitty that one can take hormonal birth control with perfect responsibility and encounter negative side effects. I also think it's really shitty that the US has the highest infant and maternal mortality rates in the developed world. I've had to deal with both sides (taking hormonal birth control, with some side effects; having a "high risk" pregnancy and being confronted with forced surgery that would increase my mortality burden, against empirical medical evidence but for insurance reasons). My philosophy is consistent: given that the hand of cards is shitty, I want to choose how I play the cards.

Ideally, as you say, folks should have full access to knowledgeable medical experts who can help guide them. Again, our mechanisms for delivery of care in the US don't allow that, and unfortunately our physician and nurse training doesn't facilitate that either. A lot of medical professionals insist that hormonal BC doesn't have side effects, many insurance companies don't cover experimentation to find the best method for a particular person, non-hormonal woman-controlled methods are underused in the US. Since medicine in the US is built around making money & defending against lawsuits, care gets lost.

kaitai··on FDA approves first nonprescription daily oral contraceptive
In the United States, there are two quite distinct aspects.

1) Health. Agree that talking to a doctor -- or a nurse, or a midwife, or a well-trained community health advocate -- is quite useful when understanding the practicalities of taking hormonal birth control. Talking to someone helps people understand this; I think you may overestimate the efficacy of an MD per se here.

2) Insurance as gatekeeper. The narrow windows to get a limited supply, whether you can get it locally or must mail order it or can't mail order it or can or can't get a refill -- none of this is medical. It's all insurance bureaucracy. I find no benefit to this bureaucracy.

Good education about the full range of options would be great (from pill to ring to IUD to condom). Universal health care availability would be a good mechanism by which to deliver that, it's hard to accomplish when it's all gatekept by insurance.

I got laid off recently & had a routine physical that took place 2 days after my health insurance thru Company ended, went anyway, got a bill for $552. This is for conversation only, haha, but the type of conversation one would need to get an annual renewal for birth control controlled by prescription.

Hah, just linked to the Minneapolis counterpart study above. Yes, this is an elegant natural data experiment, thanks for sharing this version that touches a larger dataset.

There's an elegant paper and analysis that addresses this in Minneapolis, another city that's had some DOJ attention for policing. https://lawandinequality.org/2020/11/24/does-the-minneapolis...

The TLDR is that you can analyze the difference between stops on summer evenings (sunny) and winter evenings (dark) and detect a racial bias depending on whether officer can see the driver or not. The raw data is also available through Minneapolis' Open Data website, so you can repeat the analysis yourself.

kaitai··on California needs real math education, not gimmicks
You can't get a promotion in the bureaucracy if you just "do things well". You must "innovate" and start an "initiative". Administrators also get a pay bump for completing degrees like a master's and a PhD, right? so you have to do something that pleases the advisory committee to get your pay bump. Individual incentives are really misaligned with helping kids learn math best.
kaitai··on California needs real math education, not gimmicks
Yes, agree, and this dovetails with a sibling comment by a long-time teacher. I have a child in the US and have family close in age and demographics in non-US countries. The pressure of school-as-childcare is unique to me in the US because of the amount of paid time off I get, which is substantially less than my peers in Europe. In addition, the financial pressures of childcare and education in the US are quite different than Europe. I certainly earn more money in the US than I would in Europe in the same job, but the logistics of arranging childcare and the pressure of teaching my child both math and English outside of school, despite 7+ hours of school a day, are not insubstantial. As has come up elsewhere in these discussions (on HN and in the article), 15 minutes a day of worksheets has done wonders. While I appreciate what Kid has learned in school, and very much appreciate that Kid's classmates get a nutritional baseline no matter what, it is striking that I must provide this additional instruction and practice. It's this very out-of-school intervention that leads to the inequality of outcomes I so clearly see at the school my child is departing -- one in which the kids with college prof parents score top in the state and kids whose parents are English-language learners or work several (non-adjunct-instructor) jobs score in the 30th percentile. (The kids of all the PhDs, whether well-compensated or not, do fine academically.)

Dumbing down the standards doesn't help anyone. I actually like the idea of a data science class, seems like a great motivation/way to teach algebra, but the way it's being operationally proposed in the CMF does not help. And back to my observation about the worksheets above, “This pathway leaves students unprepared for quantitative four-year college degrees via a newly proposed pathway for teaching mathematics that lacks essential content." “Instead of reducing the gap, the CMF proposal will worsen disparities as students from affluent families will access private instruction and tutors while under-resourced students will be left behind.” -- Dr. Jelani Nelson, absolutely correct.

For interesting discussion of the shoddy research underlying many of the citations in the CMF, see Mike Lawler's Twitter threads (username mikeandallie).

For a trucking job you do in general need a commercial driver's license (CDL) which has far more stringent requirements than getting a regular driver's license. Many states require an EAD (employment authorization document) to get a CDL.
kaitai··on Earth entering ‘uncharted territory’ as heat records quickly shatter
It sounds like you only care about problems that affect you very directly, which is pretty short-sighted. There are many climate-related problems that are affecting people already in Central America (no rain, can't farm, so they're walking north), the northern US and California (wildfires and wildfire smoke), the Midwest (aquifers depleted, rendering farmland less valuable), Florida (sinkholes from aquifer depletion, flooding in streets, no they can't just build a dike). It's a pretty multi-factorial problem and it's unfortunate that the interpretation here seems to be pretty simplistic.

Your does point out something, though, that really really bugs me from climate activists/politicians. The idea that you have to "believe" in climate change, like you'd believe in religious proclamations. I don't give a sh*t if you believe -- and making this ideological creates tribes where one group is like "I believe climate change isn't happening/is God's will/is natural, so I will run my F150's AC with the windows open and breathe in exhaust proudly because internal combustion and burning oil is what God has ordained as the pinnacle of human achievement". Belief whatever. I'm much more interested in action. Why does it seem good to some people to... just waste resources without much return? Irresponsibly manage our farmlands for short-term profit vs long-term yield? pin success to ownership of fossil fuels in specific places rather than a more flexible and less geopolitically fraught paradigm? There are a lot of visible problems to address, to your point, efitz.

kaitai··on Supreme Court strikes down affirmative action in college admissions
A white legacy applicant at Harvard is 5 times as likely to be admitted as a non-legacy white applicant. "Our model of admissions shows that roughly three-quarters of white ALDC admits would have been rejected if they had been treated as typical white applicants."

All of you writing that if a Black kid gets admitted then some white or Asian kid gets bumped off are scrapping for the little bits the rich have left to you, while misunderstanding the fundamental mathematics at work. You're pawns. This is the genius of racism -- sow manufactured division among the "little people" so that those on top (of whatever color) can continue comfortably while no one else can rise.

kaitai··on Supreme Court strikes down affirmative action in college admissions
That's where things fall down, though. I've done some admissions work (I am not professionally in admissions or HR or anything, I was just an academic mathematician). A lot of "qualifications" are experiences you can buy. You can buy volunteer experiences here or there, whether as literally as flying your child to Africa to volunteer or as simply as not asking your kid to contribute to paying the rent and letting them tutor for no cash. You can buy your kid test prep classes -- yes, the poor kid can get an SAT prep book from the library but the rich kid can have a tutor take their child by the hand and cajole/harass/massage the kid through test prep. You must pay pay pay to have your kid participate in traveling soccer league, dance team, lacrosse, etc. Remember travel soccer and similar activities are a way of divesting from the public schools, ensuring that this money and coaching benefits kids whose parents can pay (the right kinds of kids, the kids you want your kid to marry). What else? The music lessons, the robotics contests, the school district that has a full suite of AP or IB classes rather than just a couple, but in which houses start at $425k...

I sure as shit am buying qualifications for my kid, fully recognizing my role in participating in this flawed system. Kid's in robotics, language classes, gets to travel. We switched the kid's school to go to a school with higher standards. We teach the kid both reading (100 Easy Lessons...) and writing (workbooks from the non-US country with better public education) -- small expenses in $ but nevertheless expenses. I'm sure someone will happily tell me that the last part is just good morals on my part, or something, but you can't tell me that $100/day for a robotics summer camp is just good morals. I am buying that kid qualifications.

And then someone will tell me that's not race-based, but look at the perpetuation of wealth disparity thru US history, from chattel slavery on through the robbery from the Freedmen's Bank to the riot that burned down Black Wall Street to the fact that Black servicemen couldn't get mortgage assistance or GI Bill college assistance after WW2. Follow the money.

kaitai··on Plastics are poisoning us
Small actions on a personal level can help people feel efficacy and engage on a larger level. Political and economic action is absolutely what's most important, but humans have weird psychology. Some for instance will not engage in the larger political action because they feel they are not virtuous enough (they don't bring a plastic bag along, they don't recycle) and if they can't do the small things that they misconstrue as essential, then f*(& it might as well just run the F-150 all day in a parking lot with the windows open and the AC on and vote for drill and burn politics.

In a rock band, you have a guitarist and a drummer and a singer and a bass player. Not everyone does the same thing. We all need to contribute in different ways at different times.

Plastics are indeed everywhere and have made some aspects of daily life better while making other aspects worse. Neither of the extremes of overemphasizing personal virtue and nihilism are useful.

kaitai··on U.S. pedestrian deaths reach a 40-year high
The poster is most likely referring to laws like those in Florida Gov. Ron DeSantis's "anti-riot" bill, which was passed but eventually found unconstitutional. It gave civil protection to anyone who ran over protesters with a vehicle. Oklahoma Gov. Kevin Stitt also signed such a bill, House Bill 1674 in 2021, which says that people who run over protesters if they "feel threatened" can't be held civilly or criminally liable. North Dakota (HB 1203), North Carolina (HB 330), Florida, Tennessee, Rhode Island, and Texas also proposed similar bills. It is worth noting that several of the bills do say that if a driver wilfully runs over a protester, it's not ok, though language varies.
kaitai··on U.S. pedestrian deaths reach a 40-year high
If you want to live in the country, live in the country.

I, though, like living in my neighborhood of single-family homes & small/medium size apartment buildings, with four coffeeshops, two independent grocery stores, restaurants, local shops, and more within walking or biking distance. I like being able to take a walk to pick up some bread and eggs and buy a present for a family member (no car) and bike to a major river area where I can hike for tens of miles if I like, or even go swimming and drown (it's wild enough for that if that's what you value).

People are driving in risky ways these days, running red lights much more than they used to, but it still does feel that in my city neighborhoods, folks are more conscious of pedestrians and bikes than in the suburbs I sometimes visit for friends/kid stuff/work. In the suburbs there seem to be many wide roads (4 lanes) separating areas of cul de sacs, with 35 mph speed limits but people actually going 50. Part of this is that the city streets are packed with parked cars and there are people visibly carrying out activities of daily living, while the suburban wide streets give this impression of being cars-only.

kaitai··on I’m an ER doctor. Here’s how I’m already using ChatGPT to help treat patients
I passed this article & discussion on to physician spouse, who would specifically like me to reply to this comment: "You are being very emotional."

Digging deeper (as the comment above alone isn't worthy of HN, IMO): "People believe what they want to believe because of small sample sizes. When there isn't a black & white answer people go back to their personal experience, which is limited. They will not be right in the way you want to be right if you're practicing medicine." The family members are certainly exhibiting this. Are any of us, in this discussion?

Additional question: "Who is the patient? Is it the anxious family members who are being treated, or the person with fluid in the lungs?" The person with fluid in the lungs is the patient and the doc needs to be spending time on that person (the one who will die if not treated correctly). The family members are important but not in need of medical care. They can be handed off to an AI in the short term.

From my own vantage point, I've observed that the context switching between "caring for patient" and "dealing with family" can put a substantial drag on cognitive function for physicians. They do need to suck it up and deal with it since family members are the primary way in which patients receive post-release care in the US due to the non-existent safety net, and family member presence can really improve outcomes, but I'm not surprised that ChatGPT helps in producing the sort of bland prose that is well-received by family members.
