Availability of accepted articles:
This journal makes articles available online as soon as possible after acceptance. This concerns the accepted article (both in HTML and PDF format), which has not yet been copyedited, typeset or proofread. A Digital Object Identifier (DOI) is allocated, thereby making it fully citable and searchable by title, author name(s) and the full text. The article›s PDF also carries a disclaimer stating that it is an unedited article. Subsequent production stages will simply replace this version.
