in western countries, it seems that such problems are growing as well in these years with the "promotion" by lots of professors or researchers from Asia such as China and India. The life pressure of these professors causes them to produce results faster and get tenured faster, but normally without control of quality. Such a kind of problems are most serious in the area of engineering. It is always true if you do your research is not really from your personal interest but from some other things like your fame or money, then in general it is no way to do a high quality research. I believe you see there are many researchers who are publishing many "rubbish" papers in these days. Some guys can produce more than 12 each years. You can see how the quality will be. Either he just adds his name in other's papers without any signifcant contribution to the paper (exchang authorship), or just reformat some ideas or data from old papers, but change a little bit to produce anotehr paper. Such a kind of problems seem to be most serious in us Chinese researchers.
