Next Thursday, May 11th 2017, my colleague Robbert van Sluijs will defend his doctoral dissertation Variation and change in Virgin Islands Dutch Creole, Tense, Modality and Aspect.
In seven extensive chapters, Van Sluijs focuses on the Virgin Islands Dutch Creole TMA-system, for instance the use of a, le/lo and ka, especially in sources which are available in the Clarin-NEHOL-corpus.
The interesting book from this creolist of Radboud University Nijmegen, The Netherlands, is published by the Netherlands Graduate School of Linguistics, LOT 453. An OpenSource-version will be available in near future.

Good luck to him! The dissertation could be useful for me because I am not sure if I use tense and aspect the right way already.
