[Cool] NYTimes: Creative thinking foils car thieves

http://seattlepi.nwsource.com/opinion/230596_kristof30.html


The LoJack security system has hurt the business model of auto theft, forcing thieves to go into new lines of work -- and that should inspire us to think more creatively and systematically about how to reduce crime.

Sold for $695, the LoJack is a radio transmitter that is hidden on a vehicle and then activated if the car is stolen. The transmitter then silently summons the police -- and it is ruining the economics of auto theft.

Car theft, it turns out, is a volume business. And so if even a small percentage of vehicles have LoJack, the professional thief will eventually steal a car with one and get caught.

The thief's challenge is that it's impossible to determine which vehicle has a LoJack (there's no decal). So stealing any car becomes significantly more risky, and one academic study found that the introduction of LoJack in Boston reduced car theft there by 50 percent.

Two Yale professors, Barry Nalebuff and Ian Ayres, note that this means that the LoJack benefits everyone, not only those who install the system. Ayres and another scholar, Steven Levitt, found that every $1 invested in LoJack saves other car owners $10.

Nalebuff and Ayres note that other antitheft devices, such as the Club, a polelike device that locks the steering wheel, help protect that car, but only at the expense of the next vehicle.

An article in The Milken Institute Review proposes other ideas for reducing crime. The author, John Donohue of Yale, notes that both building prisons and adding police officers reduce crime rates. But he argues that we get much more bang for the buck by hiring police.

We have about 300,000 more prisoners than is cost-effective, Donohue calculates. In other words, every extra $100 spent on incarceration reduces crime losses by some smaller amount, say $50. But he also finds that we could add up to 500,000 police officers, and they would pay for themselves in crime savings.

Some social programs also pay for themselves in reduced crime. Donohue argues that a good bet is the Perry Preschool program (which involves weekly home visits). Its graduates end up 40 percent less likely to be arrested than those in a control group. The Job Corps for at-risk teenagers has also been shown to be very effective.

How to Fix a Jammed Toyota Camry Trunk

This problem needs a higher pagerank, so I figured I would post the solution here. If your Toyota Camry trunk won't open, one possible reason is that it is set to valet mode. Valet mode means that you cannot open the trunk using the release lever inside the car. To set valet mode, you put the key into the trunk lock and turn it counterclockwise. You will know that your trunk is in valet mode if the lock is horizontal rather than vertical, and if you cannot open the trunk using the lever near the driver's seat. Of course, a problem is that sometimes the Camry can get stuck in valet mode, such that you can't use your key to get out of it. (You can see how I spent part of my Sunday morning ...) The solution turns out to be WD-40 . Spray some WD-40 on your key and on the lock. Put the key in, and jiggle it around, and happiness ensues. From an interaction design perspective, it sort of makes sense to have a valet mode. After all, the point of having a valet key is to limit the

Web 2.0 and Research

I've been chatting with many of my friends and colleagues about an issue that's been bugging me for a while, namely whether academic research has any role to play in the emerging Web 2.0 . I've been slowly coming to the conclusion that the answer is not much. I had a similar discussion with other researchers at HotMobile a few weeks ago. When the web first came out, pretty much every systems researcher ignored it because it was so ugly. The web was not very sophisticated in terms of distributed systems, HTTP lacked elegance, HTML conflated many different ideas, and so on. There were also not any really new ideas with the web, as evidenced by the fact that Tim Berners-Lee 's first paper on the Web was (probably rightfully) rejected from an ACM conference on hypertext. I'm sure one thing that really irked researchers about the nascent web was that it completely ignored the large body of work in hypertext and distributed systems that had preceded it. Even in 1997, as

[Research] Famous Rejected Papers

I've always thought it would be fun to compile a list of famous rejected research papers, ones that later turned out to be highly influential. For example, in My Life as a Quant , the author tells the story of how the famous Black-Scholes paper (which describes how options should be priced) was rejected several times. The work eventually led to a Nobel Prize in economics. (Yes, I know, there technically is no Nobel Prize in economics). Then there's George Akerlof 's work on asymmetric information . I don't recall exactly, but I think the reviewers thought it was too simplistic. It also led to a Nobel Prize in econ. And then there's Tim Berners-Lee 's original paper on the World Wide Web. He describes his experiences in his book Weaving the Web . I think it was submitted to a hypertext conference, but was accepted only as a demo. I'm guessing reviewers didn't see much novelty in the work, which probably was correct from a research perspective.
