Writing articles based on the "Least Publishable Unit"
To summarise what's in some of the comments... this term is usually used in a cynical, sardonic or derogatory fashion, to describe the practise of "salami-slicing" research into lots of papers, each of which has the minimum amount of content necessary to get published. The aim of this approach is to maximise the number of publications that can be obtained from a given piece of research.

Some believe that this approach is encouraged by hiring practises in universities that depend upon the number of publications a researcher has, rather than their quality.
