Journal drops the ball as it tries to juggle an embargo request and Elsevier's temporary removal policy
So much for author instructions. Researchers who'd submitted a paper to Social Science & Medicine on smoking in public places briefly lost their article after the journal had some confusion about an embargo they'd requested. The article, "Neighbourhood greenspace and smoking prevalence: Results from a nationally representative survey in England," has since been republished in … Continue reading
