Criticism is made of the forestry reforms that the bank imposed in return for loans of more than $450m. Initially, said the panel, "the bank provided [to the government] estimates of export revenue from logging concessions that turned out to be far too high. This encouraged a focus on reform of the forestry system at the expense of pursuing sustainable uses of forests, the potential for community forests and for conservation.

In a scathing analysis of the bank's economic reasoning, the panel said the bank had "distorted the real economic value of the country's forests" by looking solely at the tax and revenue that increased industrial logging might generate. "There seems to have been little action to support alternative uses of the forest resources," it said.

The panel travelled deep into the forest to take evidence from the Pygmy communities, who told it they were not consulted before the bank launched its wide-ranging forestry reforms.

An important finding, Ms. Ellison said, was that students who reported low satisfaction with life and low self-esteem, and who used Facebook intensively, accumulated a form of social capital linked to what sociologists call “weak ties.” A weak tie is a fellow classmate or someone you meet at a party, not a friend or family member. Weak ties are significant, scholars say, because they are likely to provide people with new perspectives and opportunities that they might not get from close friends and family. “With close friends and family we’ve already shared information,” Ms. Ellison said.

Ms. Ellison and her colleagues suggest the information gleaned from Facebook may be more accurate than personal information offered elsewhere online, such as chat room profiles, because Facebook is largely based in real-world relationships that originate in confined communities like campuses.

Eszter Hargittai, a professor at Northwestern, found in a study that Hispanic students were significantly less likely to use Facebook, and much more likely to use MySpace. White, Asian and Asian-American students, the study found, were much more likely to use Facebook and significantly less likely to use MySpace.

ElBaradei has been vindicated in his pre-war belief that Iraq was not resuming its own nuclear arms program, contrary to claims by Bush and Cheney.

"But have we seen Iran having the nuclear material that can readily be used into a weapon? No. Have we seen an active weaponization program? No."
