I found myself in Doc's Harley-Davidson in Kirkwood recently, picking up a gift for a relative who is an avid biker. The guy in front of me was buying a shiny new helmet, which I paid little attention to until he paid the bill: about $400.
It struck me as awfully expensive, but probably well worth it considering what can happen if you fall off one of these things at a high rate of speed.
But the nation is full of "biker's rights" groups who think a rider should never be forced to buy that helmet to begin with. Somehow, amazingly, these groups are making headway (no pun intended) in getting helmet laws repealed. (They've tried and failed in Missouri.)
Right now we live in a split metro. In Missouri, you must wear a helmet on a motorcycle. In Illinois, it's not required.
Upon looking further, I have to admit being a little bit amazed to find we are one of only 20 states in the union with a law requiring the use of a helmet. After all, nearly everyone requires seat belts, and, quite frankly, I like my chances better in a car crash with no belt than a cycle crash with no helmet. (Though I don't intend to take either chance)
A blog today on the New York Times site recounts what the reporter says was an actual conversation among doctors on this issue several years ago in Los Angeles. It seems to say it all about the risk you take riding without a helmet:
"In 1992, three surgeons at a major hospital here that specializes in organ transplants met in the hospital’s cafeteria to informally discuss the California Legislature’s effort to enact a mandatory motorcycle helmet law.
“This looks like it might pass,” one doctor said. The others nodded. “This could have serious consequences for the hospital.”
“How so?” asked the doctor sitting closest to him.
“Motorcycle fatalities are not only our No. 1 source of organs, they are also the highest quality source of organs because donors are usually young, healthy people with no other traumatic injuries to the body, except to the head,” the first doctor answered. “Studies have shown that when helmet laws are enacted, motorcycle deaths significantly decrease. The hospital already has serious financial issues to deal with. This could put us out of business — or at least the business of organ transplants.”
“I’d never thought of it that way,” said his colleague. “What do we do?”
“A motorcyclists’ rights organization has contacted the hospital and asked us to join their coalition supporting what they call ‘freedom of choice,’ which is essentially the right not to wear helmets,” the doctor said. “Is this something we could in good conscience support?”
Just then the third doctor stood up and said: “I’m a member of the hospital’s ethics committee, and I can tell you, as physicians, we can’t even have this conversation.” With that, she left the room."
The motorcyclist rights people might think I'm a little lame, but guys, come on! Is it such a big deal to wear a helmet? What do you think?
What is reCAPTCHA?
reCAPTCHA is a free CAPTCHA service that helps to digitize books.A CAPTCHA is a program that can tell whether its user is a human or a computer. You've probably seen them Ñ colorful images with distorted text at the bottom of Web registration forms. CAPTCHAs are used by many websites to prevent abuse from "bots," or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.
About 60 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that's not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into "reading" books.
To archive human knowledge and to make information more accessible to the world, multiple projects are currently digitizing physical books that were written before the computer age. The book pages are being photographically scanned, and then transformed into text using "Optical Character Recognition" (OCR). The transformation into text is useful because scanning a book produces images, which are difficult to store on small devices, expensive to download, and cannot be searched. The problem is that OCR is not perfect.
reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly.
But if a computer can't read such a CAPTCHA, how does the system know the correct answer to the puzzle? Here's how: Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one. The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct.
Currently, we are helping to digitize books from the Internet Archive and old editions of the New York Times.
