I checked the link and it focusses on medical journals, so I don't know whether these two papers will be picked up. The authors are well known in the field and one is on the verge of the retirement, so flagged for life is probably not a big concern.

Also we should distinguish between two kinds of publication which could show up in this way - if two substantially identical papers by different authors appear, then plagiarism can be suspected and this is very serious. However when the same author(s) publish substantially the same paper several times then I think we have to think about the matter more carefully.

I offer my own publication record as an example. I've done a lot of research which I publish once and that is it, but I also have a couple of themes that I have been promoting, such as the use of fuzzy logic in ecology and the development of decision support systems for aquaculture licensing, which means that I have written several papers on each of these topics which overlap quite a bit. Part of the reason for this is that I have spoken about these topics at conferences, and if the conference proceedings get published then similar talks end up in print. But I think that the nature of these articles as putting forth ideas is easily distinguished from multiple publication of research results.

And of course it is not always clear how much duplication there is between papers, and an author may think that he has written a new paper that the rest of us think is just a repeat performance. I keep getting papers to review by someone who seems to me to have published the same paper several times before, but who cites the earlier papers so he certainly is not trying to cover up the duplication. So I get dragged into debates about how original the new paper is!

By the way, some colleagues of mine just scored a real scoop. They published basically the same paper in both Science and Nature simultaneously! Talk about impact factors. I really gasped when I saw this.

Really, you think. if they are so similar, they will be soon enough at the duplication database, and basically flagged for life: http://spore.swmed.edu/dejavu/

Personally, I think it despicable.
