FT.com / Columnists / Martin Wolf - Why the climate change wolf is so hard to kill off - 0 views

  •  
    Wolf - Scare + Solution is the trick fo Bali Two things are needed. The first is convincing evidence that the true risks are larger than many now suppose. Conceivable feedback effects might, for example, generate temperature increases of 20°C. That would be the end of the world as we know it. I cannot imagine a rational person who would not seek to eliminate even the possibility of such outcomes. But if we are to do that, we must also act very soon. The second requirement is to demonstrate that it is possible for us to thrive with low-carbon emissions. People in the northern hemisphere are not going to choose to be cold now, in order to prevent the world from becoming far too hot in future. China and India are not going to forgo development, either. These are realities that cannot be ignored.

Wikipedia 2.0, with added trust - 0 views

  • In the new version, only edits made by a separate class of "trusted" users will be instantly implemented. To earn this trusted status, users will have to show some commitment to Wikipedia, by making 30 edits in 30 days, say. Other users will have to wait until a trusted editor has given the article a brief look, enough to confirm that the edit is not vandalism, before their changes can be viewed by readers.

      how do we trust the trusted editor? is there a rush to become trusted editor?
  • It allows select groups of editors, probably associated with specific subject areas, to vote on whether an article should be flagged as high quality. Readers would still see the latest version of an article by default, but a link to a high-quality version, if it exists, would also be available.

      looks like an editorial committee
  • Contributors whose edits tend to remain in place are awarded high trust ratings; those whose changes are quickly altered get a low score. The rationale is that if a change is useful and accurate, it is likely to remain intact during subsequent edits, but if it is inaccurate or malicious, it is likely to be changed. Therefore, users who make long-lasting edits are likely to be trustworthy. New users automatically start with a low rating.

  • De Alfaro has shown that the software's ratings correlate with human judgements. Using data from the Italian Wikipedia, his software assigned trust ratings to editors based on the persistence of past contributions, and then asked volunteers to rate edits by those editors. Edits made by editors with ratings in the bottom 20 per cent were up to six times more likely to be judged as bad than those with higher ratings.
