Second Life

Barack Obama’s change.org website is accepting requests for ideas and projects to be implemented during his term. Knowing that he’s all for technological innovation, and that several successful experiments with e-democracy were done inside Second Life®, let’s try to push for even more. Andabata Mandelbrot is proposing that we vote to create an international metaverse - the Internet equivalent of virtual worlds. To get this implemented, we need 400 votes! And the deadline is… today at midnight, so we need to hurry… Voting is simple, you just need to create an account on the change.org account and vote (you can even log in with your Facebook or MySpace account) by clicking on the icon. If you’re willing to promote this idea, you can, of course, do more — add widgets, push it to your social network, and so on. With a surprisingly open-minded approach, voting is not limited to US residents, but it’s totally open to international voters too. The change is for America, but its impact will be global. A nice touch!

Virtual 3-D Healthcare Learning Environments

The author provides a critical overview of three-dimensional (3-D) virtual worlds and “serious gaming” that are currently being developed and used in healthcare professional education and medicine.

Roger’s Diffusion of Innovations Theory

has been heavily colonised by higher education institutions since its genesis a little over five years ago. But how useful to educators is it?

The Media Zoo's Second Life island provides a space in which students, researchers and teachers can experiment with learning in a virtual world.

Salmon believes that Second Life constitutes a good example of "edutainment" - the idea that students are more likely to learn if they are first amused. An example of how this works in practice is the programme developed for archaeology students at Leicester. While learning about the ancient culture of the Sami, the indigenous people that live in the area we call Lapland, the students used Second Life to meet in a virtual representation of one of the tents that the ancient nomads would have used for worship.

Which, annualized, gives us 1,752 kWh. So an avatar consumes 1,752 kWh per year. By comparison, the average human, on a worldwide basis, consumes 2,436 kWh per year. So there you have it: an avatar consumes a bit less energy than a real person, though they're in the same ballpark. Now, if we limit the comparison to developed countries, where per-capita energy consumption is 7,702 kWh a year, the avatars appear considerably less energy hungry than the humans. But if we look at developing countries, where per-capita consumption is 1,015 kWh, we find that avatars burn through considerably more electricity than people do. More narrowly still, the average citizen of Brazil consumes 1,884 kWh, which, given the fact that my avatar estimate was rough and conservative, means that your average Second Life avatar consumes about as much electricity as your average Brazilian.
