In the original article, the wrong author name was indicated next to the ‘Correspondence may also be addressed to’ section. It should have read as follows:

*Corresponding author: Tel +45 35325025; Email: lars.juhl.jensen@cpr.ku.dk

Correspondence may also be addressed to Jan Gorodkin. Tel: +45 35333578; Email: gorodkin@rth.dk

This has now been corrected online. The Publisher apologizes for the error.
