Guy Berger , professor of journalism at Rhodes University, has been working on ways to help editors do better for some time now. His 1998 research paper, with Peter du Toit, “Exploring training needs of editors in the countries of Southern African Development Community (SADC)” still warrants a look-see (follow links to research>leadership).
More recently, the South African National Editors Forum (Sanef) published the results of a commissioned study, “Managerial competencies among first-line news managers in South Africa's mainstream media newsrooms” , which included both qualitative and quantitative approaches and a very well-constructed sample.
To help inform the Journalism Leaders Programme at UCLan, we did a little bit of research ourselves. While I’m still working on a conference paper that will report the full results, there’re a few tidbits in a piece on our website and in another one that ran in the UK Press Gazette .
