Electronic-First Publication that an article is published as soon as it has completed the production cycle, i.e., after the page proofs are returned by the authors and prepared for electronic publication. Each article is published in its final form, including the final bibliographic citation. Readers can freely access or cite the article. New articles are added daily to the online journal, with the date of posting being listed as the publication date of the article. At monthly intervals these articles are collected together to make up the printed issues.
