I have seen that some researchers in my field, that is Computer Science, do this:
They publish a paper, for example titled "The use of the Fourier transform for problem X". The paper gets accepted.
Then after a while they have another paper titled "The use of the Fourier transform for solving the problem X under these constraints". I read the paper and I see this is the same as before with only the title changed a little bit and published in another conference.
Again, the same paper in another language "l'uso della trasformata di Fourier...", which has the same content, but submitted to a local conference
Is this alright? For me it just seems that it should only be put like one publication under their CVs and not "resell" the idea over and over. I have this question because they had asked me to translate one of my papers to a local conference, but I do not consider that to be like a new publication. Should I translate and claim a new publication?
