Obviously the person you are referring to hasn’t done anything new for awhile, but wants to maintain his/her publishing profile. Lazy so-and-so.
I find it really aggravating, as these sorts take up space in journals that could be used to present new research.
The defence is that the previous RAE assessment criteria required ‘output’ – almost to the point of not caring what it was/how many repeat papers you coudl get (my PhD supervisor got at least 5 out of one subset of my data) – as a judge of research quality and therefore future funding, so it’s just playing the game. As I understand it, the last (and future) RAE’s focused more on quality/uniqueness but was a ball-ache to administer and the gradings were not entirely subjective (quality being determined by a panel in each subject area, all with their oven axes to grind!)…
