The journal impact factor (IF) 2010 and quartile (Q) ranking position for each journal were also retrieved
from JCR. Journals are generally sorted into quartiles for research evaluation systems in order to overcome the bias related to the direct comparison of the IF scores of journals that are Quisinostat price listed in diverse subject areas. Quartiles, a division into four equal percentiles of the journals listed in a category, are also used by the Italian Ministry of Health to evaluate publications authored by the research institutes of the National Health Service [7, 8]. The survey examined publishers, business models (subscription-based, full open access, hybrid open access), and publication fees per article. To allow easy price comparisons, the costs were also calculated in euros where prices were reported only in US dollars and/or GB pounds, according to the GS-1101 clinical trial exchange rate of 27 August 2012. It should be noted that authors are sometimes charged additional costs for extra pages, colour tables or figures, reprints, etc. Data relating to the
journals’ business models were retrieved by searching the SHERPA/RoMEO [9] database which draws a distinction between the following journal categories: subscription-based journals, full OA and hybrid OA journals. This database was also a privileged source of information for quickly identifying Megestrol Acetate features of the single journals surveyed, such as the publisher’s name and copyright policy, in regard to both the regulation of intellectual
property rights and the level of openness of self-archiving. With respect to this latter point, the SHERPA/RoMEO database groups Selleck Roscovitine publishers in four different colours, from those with more permissive conditions to those with a stricter approach, as follows: green indicates publishers that permit archiving of pre-print, and post-print or publisher’s version/PDF; blue indicates those that allow archiving of post-print (i.e. final draft post-refereeing) or publisher’s version/PDF; and yellow those that permit archiving of pre-print (i.e. pre-refereeing); white indicates publishers that do not support any archiving. Other aspects considered in this survey concern the copyright policies relating to current publishers of the journals listed in Table S 2. The most widely used models are: Copyright Transfer Agreement (CTA), Exclusive Licence Form (ELF) and Creative Commons Attribution (CCA). The author signing the CTA transfers all exploitation rights (in terms of re-use and redistribution of an article for educational or commercial purposes) to the publisher, except the moral ones (paternity and integrity rights).
