Dear Jodi,

1) I agree with you that a more granular roles differentiation is possible, but the question we are asking is which type of editors are leaving: the new ones or the more senior ones. Thus, we want first to shed light on who is leaving. A subsequent step could be a further categorization as you suggest to paint a more detailed picture.

2) Thanks for all the references, I will download those papers and have a look.
