In many journals associate editors play an important role in the review process but their names don’t appear in communications with authors. At Europ Soc Rev, when we reject a paper the letter is signed by both EiC and AE. In others only the EiC signs. Having the AE in the letter adds transparency

“Over the past 20 years, Paris has undergone a major physical transformation, trading automotive arteries for bike lanes, adding green spaces and eliminating 50,000 parking spaces.

Part of the payoff has been invisible — in the air itself.”

Leadership, strategy, real action, common sense. #Paris
Paris said au revoir to cars. Air pollution maps reveal a dramatic change.
Air pollution fell substantially as the city restricted car traffic and made way for parks and bike lanes.
