Airlines Face Acute Pilot Shortage

John Newman Re:Overregulation = poor customer experience (421 comments)

The shortage of doctors in the U.S. is due to the AMA cartel's control over university accreditation and corresponding rent-seeking state laws requiring accreditation. The result is speed-exams when you go visit a doctor (or maybe not see the doctor at all, but rather a "nurse practitioner").

The situation of pilots and doctors does seem similar on several levels, but I think you're drawing the wrong conclusions.

The proximate cause of the "speed-exams" is not a doctor shortage, but an artifact of how most doctors are paid - by the visit. You get a tiny bit more money for a long, complicated visit, but not nearly as much as if you see two or three patients in the same time. This is true for almost every payer - private insurance, Medicare, Medicaid, etc. The financial incentives are strongly on the side of the speed-exam.

A more fundamental question is why the financial incentives matter so much, and that's where I think the pilot and doctor stories have some overlap. These are both highly skilled professions with a long, poorly paid training period and a strong incentive on the part of the "payers" to keep downward pressure on wages. Every time an insurance company or Medicare cuts their provider reimbursement rate, the incentive to cram more visits into a day grows that much stronger, because when you start your career at 30 or 35 with hundreds of thousands of dollars in loans, it's hard to take an arbitrary pay cut. (Talking about primary care doctors here, the situation may be different for the "lucrative" specialist du jour.)

Besides, the US actually has plenty of doctors, similar per capita numbers to Canada or the UK. But the financial incentives drive too many of them to lucrative specialties and urban practices, leaving too few doing primary care or working outside the big cities. Attempting to control costs by cutting doctors' fees creates perverse incentives.

The rise of nurse practitioners is more of an alternative attempt at cost control than a response to too few doctors. If you don't need 8 years of school and training to take blood pressure readings or insert an IV, and these things are actually done better by people who do them all the time, maybe some aspects of primary care can be done better by people with shorter but more focused training.

Engineer Thinks We Could Build a Real Starship Enterprise In 20 Years

John Newman Re:gravity wheel has weird orientation wrt thrust (589 comments)

So every loop around the gravity wheel you go through 2A of gravity variance As the +A thrust vector rotates from your feet to head and side to side of you.

Sea-sickness prevails.

At 1G constant acceleration (flipping around mid-way) you'd reach Mars in about 3 days. (Avg Distance 225M km, travel time to half-way point at 10m/s/s = 42 hrs).

Stretching the trip to 90 days works out to 0.0015G acceleration throughout. I'm guessing the crew wouldn't notice that.

[Moral: When talking about acceleration, 1 G is a *lot*. It'll get you to alpha centauri in 4 years!]

Does Higher Health Care Spending Lead To Better Patient Outcomes?

John Newman Is this a trick question? (504 comments)

Canada has an efficient and effective single-payer system. When you are already spending money well, spending more money might be better.

The US has a fragmented, inefficient, and often ineffective hodgepodge of systems. When you are already spending money poorly, spending more money might be worse.

Or, put another way, Canada is probably somewhere to the right-of-peak on the Laffer curve of health care spending vs outcomes. The US is far, far to the left.

US Research Open Access In Peril

John Newman Re:Shouldn't all work by public employees be open? (237 comments)

I work for the government and every once in a while my boss says I should try to patent it.

Do you work for the federal government? Work done by an employee of the federal government in the course of his/her duties is public domain. There's not even a question of patent or copyright, it's public domain by law.

If it's work on your own time that's not part of your official duties, however, you can do whatever you like with it.

Copyright Claim Sets Back Cognitive Impairment Testing

John Newman Re:Apologies (116 comments)

My apologies, I meant permissive-with-a-small-p only as an antonym for restrictive. I admit I wasn't aware of the technical meaning. Thank you for pointing it out. I think the phrasing still made sense to most readers. Remember that for most of the physicians who read NEJM this was probably the first time they had even heard of copyleft.

Copyright Claim Sets Back Cognitive Impairment Testing

John Newman Re:And ? (116 comments)

The people who devised the test spent time and money to do so. They created the original work. Why shouldn't they be able to license it for fee to others? They've got college loans to pay off. OH so now educators and researchers have to live under the specter of copyright laws! Boo hoo welcome to the real world!

I am one of the authors of the NEJM article.

We did not get into ethical issues in the article. But much of the current value of the MMSE does not lie in its contents but rather in the past 35 of research on it. Hundreds or thousands of studies from researchers around the world have shown doctors in exquisite detail exactly how and when to use the MMSE to best care for patients.

It is this vast accumulation of data on the validity and utility of the MMSE that makes it so valuable - and little of this was done by the MMSE's authors or PAR. In fact, much of this research might never have been done if the MMSE had had its current strict licensing terms 30 years ago. Some people have compared this behavior - waiting until the test is ubiquitous to start enforcing copyright - to patent trolls.

Nevertheless, the MMSE authors and PAR are entirely within their legal rights, and that is why we suggest that policy needs to change to prevent this from happening all over medicine.

Copyright Claim Sets Back Cognitive Impairment Testing

John Newman Re:Apologies (116 comments)

Sorry, I didn't see that the summary incorrectly states that the authors of the older test were claiming infringement. AFAIK, they're not.

I guess I failed the comprehension test. Actually, I didn't really read the summary carefully, since I was already familiar with the actual facts.

I am one of the authors of the NEJM op/ed article.

It is all a little confusing. There are three parties here:
1. The original authors of the MMSE, who through PAR are strictly enforcing copyright protections of the MMSE
2. The authors of a new tool, the Sweet 16, which was created as an open-access alternative to the MMSE but was "taken down" by PAR in a copyright dispute
3. Us, the authors of TFA, who have no relationship to #1 or #2 but are very worried about what this all means for the practice and progress of medicine

Copyright Claim Sets Back Cognitive Impairment Testing

John Newman Re:Not a big loss (116 comments)

I'm not saying the MMSE is useless, it's just no big loss if there is copyright being claimed now. We'll move on to something else.

I'm one of the authors of the NEJM article.

People already are moving on. In our practice we mostly use the Montreal Cognitive Assessment (MOCA) for screening, which is much more sensitive and has liberal licensing terms for non-commercial use.

But this is a general issue. The Sweet 16 was an attempt to move on, halted by PAR. I'm surprised that PAR hasn't already sued the MOCA authors given that the MOCA includes recall and orientation, like the Sweet 16. Even if it survives, the MOCA is not perfect- it has laudably generous licensing terms for copying, but no provision for derivative works. In 80 years, the heirs of the MOCA authors might well start suing researchers who use a trails test, clock draw and animal recognition in a new test.

Whether we move on from the MMSE or not, the threat to scientific progress will remain.

Copyright Claim Sets Back Cognitive Impairment Testing

John Newman Re:Sweet 16 vs MMSE (116 comments)

I'm one of the authors of the NEJM article.

We didn't have the space to describe the MMSE and Sweet 16 in detail, but here's a brief description:

The MMSE has 30 items, which include 10 orientation questions (what's today's date, where are we, etc.) and 6 questions for recall (say 3 standard words, repeat them back and remember them for 5 minutes or so).

The Sweet 16 has 16 items which include 8 orientation questions and 6 questions for recall (using different words than the MMSE). The other two questions involve repeating a sequence of numbers backwards.

So there is a lot of overlap between the two tests, and that was presumably the basis for an infringement claim. However, the items that overlap - orientation and recall - are quite generic and were in wide use long before the MMSE was created in 1975. Nevertheless, the authors behind Sweet 16 and their institution could not or chose not to defend the Sweet 16.

It's a little hard to imagine a cognitive assessment tool that doesn't include orientation or short-term memory recall questions, so this will strongly discourage progress in the field. Perhaps one of the Alzheimer's advocacy groups will take notice and defend researchers trying to advance the state of the art.

Copyright Claim Sets Back Cognitive Impairment Testing

John Newman Re:They did. Didn't help. (116 comments)

I'm one of the authors on the NEJM article.

The developers of the Sweet 16 - the test apparently "taken down" for copyright infringement of the MMSE - were all Harvard faculty, and work for academic centers that are affiliated with Harvard and its hospitals (Hospital Elder Life Program, Institute for Aging Research and Hebrew Senior Life). The senior author of the Sweet 16 is a well-known Harvard professor. One of the things we find concerning about this case is that Harvard Medical School probably has some claim to ownership of the Sweet 16, and was presumably involved in its defense. If Harvard, with its vast resources, could not or chose not to defend the Sweet 16 successfully, what hope do any other researchers have to develop new cognitive testing tools?

Startup Flees To Seattle Amid Amazon's Tax Fight

John Newman Fear of Amazon, not CA (235 comments)

These guys aren't fleeing to Seattle because they fear the big-bad regulations of the People's Republic of California. They're fleeing out of fear of Amazon. Amazon's response to the sales tax proposal was to threaten to disown all of its affiliates in California, since the physical presence of affiliates was one of the justifications for asking them to collect sales tax. Amazon would rather stick a knife in the back of all of its partners, putting who knows how many people out of business, than collect a nickel of sales tax from its customers. They can't pull the same thing in Washington because it's hard to deny that giant former hospital on top of a hill with an Amazon logo already constitutes a physical presence.

They left San Francisco because the Bezos bear was gonna swat them out of spite, so they went to cuddle up next to it.

And this "startup" is two guys. Fine, maybe they'll make it big one day, sounds like they got plenty of capital. But it's still two guys. Why does the decision of a two-guy business rate a headline?

S&P's $2 Trillion Math Mistake

John Newman Re:Too good credit rating anyway (1040 comments)

We never did pay off WWII debt, and we never will. Modest inflation and a growing economy make perpetual deficits and debt trivial, if they are reasonable. Yet our national economic policy is to minimize inflation at all costs, regardless of unemployment or a flat economy. So we now have near-deflation with near-zero long term nterest rates, yet horrific unemployment and an economy about to enter recession again. What's the problem with our debt again?

Senators Want Secret Warrantless Wiretap Renewal

John Newman Re:Mod parent up (198 comments)

We need to return to Clinton administration levels of spending, adjusted for inflation of course. We can't keep the Obushma empire going.

With you 100%, but it should be noted we're not that far off from Clinton levels of spending and will more or less reach it once we wind down our two land wars in Asia. We've cratered revenues, however. If we returned taxes to Clinton levels, we would have a small enough deficit that Republicans would be back to calling for tax cuts to prevent a surplus, instead of tax cuts for whatever reason they give now.

McCain Decries "Hobbits," Accused of Ringbearing

John Newman Re:Easy enough (722 comments)

If we had more local control over our lives, your argument would carry much more weight. You could say, "If you hate government so much, move to Mississippi. Seriously." and you would know that the person you are talking to could truly move to Mississippi. Of course, if they are already in MS, you could tell them to keep their noses out of your state's business.

And that works not at all for the three things our federal government spends >75% of its budget on: defense, health care, and social security. Is Mississippi going disown protection from the US Army? Does it make the slightest bit of sense to have a "young whuppersnapper" state with no social security and an "old fart" state that everyone moves to when they're 65? This would make it impossible to have such programs at all (including an Army), or at best would make people a prisoner of whatever state they were lucky enough to be born in. Forget about the problem of Mississippi's toxic waste and air pollution flowing into the next state over.

Re. medication requiring a prescription:

John Newman Re:Completely? (550 comments)

The only thing wrong with health care in the US is greedy doctors and hospitals that take advantage of the ignorance of the general public, and keep them that way by refusing to disclose information until forced to. Fixing those issues would truly lower costs of health care for everyone.

The technical term for "greedy doctors and hospitals" is fee for service system. The underlying problem is that doctors get paid for doing more, without respect to what's medically needed.

The solution is a system where all doctors are paid on salary and hospitals in lump sums, so they don't make any more or any less based on how much they do. The only motive is to provide good care, not to find ways to game the system and make more money. This is usually called socialized medicine and the VA is the best US example of it, providing better care (by objective measures) than any fee-for-service or for-profit company in the US for vastly lower costs.

Wouldn't it be nice if we all, not just veterans, had access to a socialized medicine system, where we can all get the care we need, no more and no less?

On Monday, AT&T Customers Enter Era of Broadband Caps

John Newman Re:Switch to Sonic.net (537 comments)

I just switched to Sonic from AT&T DSL when we moved last week. I've fallen in love with Sonic and their Fusion service. This is where they use their own equipment at central offices and offer as much speed as you can get, up to 20Mbps, for a flat $40/mo. Highly recommended.

I didn't particularly have a problem with AT&T before, but when we decided to move less than a mile across the city I was told:
1. I couldn't keep my phone number
2. I had to buy a new DSL modem, even though mine was AT&T recommended and less than 6 months old
3. I had to switch to U-Verse, which meant paying more for less download speed

I understand the technical rationale behind some of this (we'd be served by a different central office that was exclusively U-Verse, which uses a different flavor of DSL, etc.) but it was a lot of shit to swallow in one gulp. And then I heard about the upcoming caps, too. We watch a lot of Netflix and would probably hit it regularly.

Sonic told me:
1. Sure, I can keep my old phone number
2. I can use my current modem
3. I'll get speeds at least as good as before for the same money
4. No speed limits (you get whatever your line can handle), no bandwidth caps
5. Free POTS phone service, just tossed in there

And it's been a pure pleasure to deal with them. Local human beings on tech support, who know what they're talking about, 7 days a week, never more than a minute on hold.

I love it. I wish the local infrastructure were better, so I could get better than 3.5/1 in the middle of San Francisco, but I love everything about Sonic so far. This is what telecom service is supposed to be like.
