«Large numbers of journal articles to write»

I am under a lot of pressure to write large numbers of journal articles. I have a great empirical data set. I can either write a number of smaller papers form this data or I can write one big paper. Which would you recommend?

I would always recommend to go for one fantastic paper rather than slicing data up and producing a number of mediocre papers. More mediocre papers may help your performance statistics in the short term, but on the long term your reputation as a researchers who produces high quality work and conducts themselves with integrity is much more important. Always choose quality over quantity.
