Editorial boards usually do not pay attention what information should user write in the user profile. There might be different reasons why editorial boards do not pay attention to that very important part.
Actually, some authors really appreciate your journal and they would like to identify themselves with your journal.
Someone may ask: Well, math, chemistry, physics etc. do not have anything to do with someone’s culture.
Although we may argue about that and present a huge amount of information about interrelatedness of science and culture it is good to point that in some cultures middle name, suffix, gender or other personal details may be very important part of someone’s identity.
Do we want to ignore that even if price of that will be that the user (reader, reviewer, author, librarian etc.) might feel neglected, not respected, discouraged or hurt?
When I train users to use the Open Journal Systems I explain them that such fields are very important and that editorial board that takes care about their users should in manuals and other information blocks encourage users to create their profiles in a way that does not push their culture in the backyard. If someone’s name contains name of mother, grandmother or father and grandfather that should be put inside whatever it is personal cultural belief of member of editorial board. If author asks editor to take into consideration religious holidays during which author will not be available that should be taken into consideration and the field Comments for Editor should be understood as completed in a legitimate way.
Your users are not genderless, depersonalized entities without culture regardless of scientific research they could be interested in. Encourage them to be open and free to express all cultural characteristics and to contribute where possible to make your journal appreciated to people from different cultures.
