[Off Topic] Hsieh Forbes Column: The New Congress Should Propose Free-Market Health Care Reforms

[Off Topic]: My latest Forbes piece is now up: "The New Congress Should Propose Free-Market Health Care Reforms".

There's no shortage of good ideas for free-market health care reform. What we're lacking is leadership.

Best Media Corrections of 2014

"The year in media errors and corrections 2014".

Their winner was this from the New York Times:
An earlier version of this column was published in error. That version included what purported to be an interview that Kanye West gave to a Chicago radio station in which he compared his own derrière to that of his wife, Kim Kardashian. Mr. West’s quotes were taken, without attribution, from the satirical website The Daily Currant. There is no radio station WGYN in Chicago; the interview was fictitious, and should not have been included in the column.

Walmart Gift Card Exchange

Walmart will exchange other stores gift cards for non-expiring Walmart card dollars (at a discount):
Shoppers won't get the full value of their gift cards to use at Walmart. For example, with Amazon.com, customers can redeem up to 95 percent, while for Staples that figure is up to 90 percent and for Gap, up to 85 percent. Some brands will be worth just 70 percent. Up to about $1 billion worth of gift cards will go unused this year, according to CEB TowerGroup. That's because recipients either lose them or can't figure out what to buy.

Interview With Diana on "Radiology In Practice"

Announcement: On Thursday evening, philosopher Dr. Diana Hsieh will interview me about "Radiology in Practice" on her live internet radio show, Philosophy in Action. This episode of internet radio airs at 6 pm PT / 7 MT / 8 CT / 9 ET on Thursday, 18 December 2014, in the live studio.

If you miss that live broadcast, you can listen to the podcast later. Here's a bit more about the show:
Most people have seen cool medical imaging devices such as CT and MR scanners on TV shows. But what do those machines really do? Advanced medical imaging has revolutionized patient care in the past 25 years, allowing doctors to make diagnoses more accurately, quickly, and safely than ever before.
Radiologist Paul Hsieh will discuss the basics of modern radiology (x-rays, MRI, ultrasound, and nuclear medicine), how these different tests work, what they show about the human body, and how they help doctors take better care of patients.
To join the live broadcast and its chat, just point your browser to Philosophy in Action's Live Studio a few minutes before the show is scheduled to start. By listening live, you can share your thoughts with other listeners and ask follow-up questions in the text chat. The podcast of this episode will be available shortly after the live broadcast here: Radio Archive: 18 December 2014.

Crappy Magazines in Doctors' Waiting Rooms

Science Has Spoken! "Researchers Finally Figured out Why Doctors’ Waiting Rooms Have Such Crappy Magazines" (Slate, 12/13/2014).

From the Slate article:
Bruce Arroll, a doctor and professor at the University of Auckland in New Zealand (apparently this is a global problem) gathered up 87 new and old magazines (a number determined by "how many magazines the investigators could rustle up from family and friends") covering a variety of topics and placed them in the waiting room of his practice.
It turns out that if there are current magazines around, people steal them.
Jerks.
Here's the original British Medical Journal article: "An exploration of the basis for patient complaints about the oldness of magazines in practice waiting rooms: cohort study" (12/11/2014).

From the BMJ article:
"Figure 1. Survival probability for gossipy and non-gossipy magazines in waiting room"















Personal case example: When I went to take my father to a doctor's appointment in Los Angeles earlier this year, they had this 1987 (!) magazine in the waiting room.

I'm pretty sure this falls in the BMJ "non-gossipy" category.

How the Perfect Car Door Sound Is Made

Lots of science behind making the perfect card door sound.

From the article:
Some of the most advanced uses of these techniques today are found in the high-end automotive industry, where engineers and designers now routinely lavish attention on every acoustic detail, from the sound of the engine to cabin noise to the squeak of the windshield wipers to the reassuring k-thunk of a car door closing — a subtle but remarkably influential sound when it comes to a potential customer’s decision to buy a new car, experts say.

“The customer may not really know this is important for him, but this is something that really affects his decision to buy a car,” says Florian Frank, Specialist for Noise, Vibration and Harshness who works on acoustical design for BMW and is responsible for perfecting the sound profile of new car designs.

For example, the new BMW 4 Series Gran Coupe is “a sporty car, so the door isn’t supposed to sound too heavy. It can’t sound too light, because a light door wouldn’t convey the right aspects of quality and safety. But it’s not supposed to sound too heavy, either. It should have a precise sound.”

By contrast, “the BMW 7 Series would be a bit softer maybe, a bit darker in the sound as it’s our flagship sedan.”

18th Century Law To Defeat Encrypted Smartphones?

Feds invoke 18th century law to attempt to defeat smartphone encryption.

From the article:
[T]he Department of Justice (DOJ) is pursuing an unusual legal strategy to compel cellphone makers to assist investigations.

In both cases, the seized phones—one of which is an iPhone 5S—are encrypted and cannot be cracked by federal authorities. Prosecutors have now invoked the All Writs Act, an 18th-century federal law that simply allows courts to issue a writ, or order, which compels a person or company to do something.

Some legal experts are concerned that these rarely made public examples of the lengths the government is willing to go in defeating encrypted phones raise new questions as to how far the government can compel a private company to aid a criminal investigation...

The two orders were both handed down on October 31, 2014, about six weeks after Apple announced that it would be expanding encryption under iOS 8, which aims to render such a data handover to law enforcement useless. Last month, The Wall Street Journal reported that DOJ officials told Apple that it was "marketing to criminals" and that "a child will die" because of Apple’s security design choices...

But, if Apple really can’t decrypt the phone as it claims, the point is moot.

Peer-Review Scam

Nature: "Publishing: The peer-review scam".

It's a lot easier to get published, when you are the "impartial" anonymous reviewer of your own paper!
In the past 2 years, journals have been forced to retract more than 110 papers in at least 6 instances of peer-review rigging. What all these cases had in common was that researchers exploited vulnerabilities in the publishers' computerized systems to dupe editors into accepting manuscripts, often by doing their own reviews. The cases involved publishing behemoths Elsevier, Springer, Taylor & Francis, SAGE and Wiley, as well as Informa, and they exploited security flaws that — in at least one of the systems — could make researchers vulnerable to even more serious identity theft.
