Wikipedia?.

I appreciate the comments on my last post.

In terms of student privacy I already include in my syllabus a statement that the other students in the class will see student posts in the Bb discussion board and I suggest that if a student is uncomfortable with that circumstance that they should withdraw from the class (nobody ever has).

In terms of legalities, I wonder if an obvious answer is to simply use Wikipedia as the class site. I start an article and show the students how to add, edit, etc. Would the legal onus then fall on Wikipedia and not on me?

Toyota Creating In-Vehicle Alcohol Detection System. srizah writes "Toyota is developing an Alcohol Detection System that can detect drunken drivers and would immobilize the car when it detects excessive alcohol consumption. From the article: 'Cars fitted with the detection system will not start if sweat sensors in the driving wheel detect high levels of alcohol in the driver's bloodstream, according to a report carried by the mass-circulation daily, Asahi Shimbun. The system could also kick in if the sensors detect abnormal steering, or if a special camera shows that the driver's pupils are not in focus. The car is then slowed to a halt, the report said.'"[Slashdot]

A conversation with Graham Glass about the future of education.

This week[base ']s podcast is a conversation with Graham Glass, a software veteran who[base ']s self-funding the development of edu 2.0, a web-based educational support system. It seems like a big change from Graham[base ']s previous projects: ObjectSpace Voyager, The Mind Electric[base ']s Glue and Gaia, webMethods Fabric. But not really, says Graham. It[base ']s always been about the reuse of components, whether they[base ']re software objects or learning objects.

Graham and I share a passion for project-based learning, and in the podcast he refers to an EdVisions video on that subject which you can find here. I also (again) referenced the extraordinary talk by John Willinsky which I discussed and linked to here.

I know that technologists always say that the latest inventions are going to revolutionize education, and I know that mostly hasn[base ']t been true. Still, I can[base ']t help but think that we[base ']re on verge of a dramatic overhaul of education, and that systems like the one Graham is building will play a key role in enabling that to happen.

How ExxonMobil Funded Global Warming Skeptics. Erik Moeller writes "According to a report by the Union of Concerned Scientists, oil company ExxonMobil 'has funneled nearly $16 million between 1998 and 2005 to a network of 43 advocacy organizations that seek to confuse the public on global warming science.' The report compares the tactics employed by the oil giant to those used by the tobacco industry in previous decades, and identifies key individuals who have worked on both campaigns. Would a 'global warming controversy' exist without the millions of dollars spent by fossil fuel companies to discredit scientific conclusions?"[Slashdot]

Trusted feeds.

As several folks rightly pointed out in comments here, a community site based on tagging and syndication is exquisitely vulnerable to abuse. In the first incarnation of the photos page, for example, a malicious person could have posted something awful to Flickr and it would have shown up on that page. Flickr has its own abuse-handling system, of course, but its response time might not be quick enough to avert bad PR for elmcity.info.

...

Of course anything short of frictionless participation is an obstacle. On the other hand, based on my conversation with Paul English about customer service, there[base ']s a lot to be said for a required step in the process that forms a human relationship [~] attenuated by email, true, but still, a relationship.

I think it[base ']s even more interesting when the service, or site, is rooted in a geographical place. On the world wide web, I[base ']m always forming those kinds of relationships with people I will never meet. But on a place-based site, I may already have met these folks. If I haven[base ']t yet, I might still. Trust on the Internet has a very different flavor when the scope is local.

...

Similarly, when it was suggested that people could produce news about the local issues where they are stakeholders and have important knowledge, the pushback was: [base "]But you can[base ']t trust random information on the Internet.[per thou]

I found that fascinating. Here were a bunch of folks [~] a hospital administrator, a fire chief, a school nurse, a librarian [~] who all know one another. What they seemed to be saying, though, is the Internet would invalidate that trust.

Now I assume that they trust emails from one another. Likewise phone calls, which are increasingly carried over the Internet. And if the fire chief wrote a blog that the school nurse subscribed to, there would be no doubt in the mind of John, the school nurse, that the information blogged by Mary, the fire chief, was real and trustworthy.

Until you join the two-way web, though, you don[base ']t really see how it[base ']s like other familiar modes of communication: phone, email. Or how the nature of that communication differs depending on whether the communicating parties live near one another.

If feeds begin to flow locally, it[base ']ll be easy to trust them in a way that[base ']ll supply most of the moderation we need. The problem, of course, is getting those feeds to flow. Bill Seitz asked:

So you think the [base "]average[per thou] person will have Flickr and del.icio.us accounts in addition to joining your site?

No, I don[base ']t, though over time more will use these or equivalent services. So yes, I also need to show how any online resource that[base ']s being created, anywhere, for any purpose, can flow into the community site. It only takes two agreements:

  1. An agreement on where to find the source.
  2. An agreement to trust the source.

In the short-to-medium term, those sources are not going to be friendly to me, the developer. So I[base ']ll have to go the extra mile to bring them in, as I[base ']m doing on the events page. [Jon Udell]

Researchers Find Potential Cure for Cancer. MECC writes "Researchers at Johns Hopkins University may have found a way to kill cancer cells without radiation or toxic chemicals. The group is taking the step of patenting the idea, as this new approach using sugars may hold real potential for the fight against cancer. This is not the first approach to use sugars, the article states, but is (by the researchers' estimation) the most successful. From the article: 'Sampathkumar and his colleagues built upon 20-year-old findings that a short-chain fatty acid called butyrate can slow the spread of cancer cells. In the 1980s, researchers discovered that butyrate, which is formed naturally at high levels in the digestive system by symbiotic bacteria that feed on fibre, can restore healthy cell functioning ... The researchers focused on a sugar called N-acetyl-D-mannosamine, or ManNAc, for short, and created a hybrid molecule by linking ManNAc with butyrate. The hybrid easily penetrates a cell's surface, then is split apart by enzymes inside the cell. Once inside the cell, ManNAc is processed into another sugar known as sialic acid that plays key roles in cancer biology, while butyrate orchestrates the expression of genes responsible for halting the uncontrolled growth of cancer cells.'"[Slashdot]
