Today my dissertation was included in the Radboud Repository, the electronic deposit of academic publications of the university library of Radboud University (Nijmegen University). This is the link to it, which you should also use when you want to refer to or cite and quote my dissertation of 2003: http://repository.ubn.ru.nl/handle/2066/76506
Anyone interested in my work on signing chimpanzees can download the dissertation there directly, there is no subscription or anything needed.
To include my work in a reference list, the APA style reference would be like this:
Rivas, E. (2003). GIMME GIMME GIMME. The recent signing behaviour of chimpanzees (Pan troglodytes) in interactions with longtime human companions. Retrieved from http://repository.ubn.ru.nl/handle/2066/76506
I feel great and proud about all this! Finally my work is published and open for anyone to read. Years of hard work have reached fruition at last.
