Matt Damon, an expert on celebrity, discusses Sarah Palin’s celebrity in America:

Wikipedia will tell you that cancer is a disease where cells grow uncontrollably. They invade and spread due to carcinogens like tobacco, radiation, chemicals and infectious agents. I can not help thinking about this horrible disease when I read about Palin’s effect on America. Her love of big money from elites and her sad cronyism is obvious to anyone who looks at her record.

Palin is the Ted Haggard of politics.

Sadly, some are starting to point out “What’s the Matter with Kansas” is now growing into a national issue — self-defeatism has metastasized. While Kansas has only just started to recover and get its legs back under Kathleen Sebelius, Palin is growing in popularity at a national level among those who will be the most economically and socially devastated if she is elected.

Some people see this and are reporting on it, such as Jonathan Freedland who has published an opinion piece called “The world’s verdict will be harsh if the US rejects the man it yearns for”.

We know one of Palin’s first acts as mayor of tiny Wasilla, Alaska was to ask the librarian the procedure for banning books. Oh, but that was a “rhetorical” question, says the McCain-Palin campaign. We know Palin is not telling the truth when she says she was against the notorious $400m “Bridge to Nowhere” project in Alaska – in fact, she campaigned for it – but she keeps repeating the claim anyway. She denounces the dipping of snouts in the Washington trough – but hired costly lobbyists to make sure Alaska got a bigger helping of federal dollars than any other state.

She claims to be a fiscal conservative, but left Wasilla saddled with debts it had never had before. She even seems to have claimed “per diem” allowances – taxpayers’ money meant for out-of-town travel – when she was staying in her own house.

Yet somehow none of this is yet leaving a dent. The result is that a politician who conservative blogger Andrew Sullivan calls a “Christianist” – seeking to politicise Christianity the way Islamists politicise Islam – could soon be a heartbeat away from the presidency.

Not just the world, the good honest hard-working Americans increasingly will be forced to be harsh on themselves if Palin is elected. We have seen it already in the wake of her work in Alaska — good people fired and replaced with cronies as Palin cuddles big money and pushes a hypocritical agenda of self-promotion.

The Evangelical Right Quiz is like a health check at the doctor. The question is whether the country is ready to start treatment, or if the mutation has spread too far and will be terminal to democracy in America.

Pun intended. I can see how normal gait analysis helps people with ailments, and thus justifies the expense of development. Mitigating health risks makes sense to me so I expect more gait analysis in medical research.

However, an example of satellite gait analysis posted on Bruce’s blog sounds like a westernized solution still looking for a problem. Perhaps someone wants to be able to find and recognize people from far, far away?

It seems to me that anyone who does not want to be recognized still can easily avoid a radar and camera gait analysis system from hundreds of feet away, let alone hundreds of miles away from space.

Shadows of a long dress, a tunic (e.g. a shalwar kameez) or a long coat, for example, would render a shadow analysis system useless, no? What about from shoes with wheels in the heels? Terrain also matters. The systems probably assume a hard surface like pavement. Also, it has been mentioned many times here and elsewhere that a simple change in shoes can alter gait.

I wonder if Auburn University scientists realized their research into orthopedic problems from flip-flops was also documenting a major flaw in gait analysis systems.

Shroyer’s team, under the direction of Dr. Wendi Weimar, associate professor of biomechanics and director of the department’s Biomechanics Laboratory, found that flip-flop wearers took shorter steps and that their heels hit the ground with less vertical force than when the same walkers wore athletic shoes. When wearing flip-flops, the study participants did not bring their toes up as much during the leg’s swing phase, resulting in a larger ankle angle and shorter stride length, possibly because they tended to grip the flip-flops with their toes.

Did I mention walking under trees…perhaps the satellite system assumes there soon will be no vegetation. I would say it is more useful in arid regions, but walking on sand goes right back to the issue of terrain.
