I got some good news. Firstly, I obtained a provisional ethical clearance only with minor changes which is unbelievable. Many people complained about the long process of ethical clearance. I just got through pretty easily.
Secondly, organisations who I can access required to see my research summary. My supervisors had to work on it. It was just a lucky as those organisations were really supportive. I think I can access at least two organisations.
Thirdly, I got an official letter from the Graduate Student Office that I was certainly confirmed as a PhD candidate with no revision. This was a miracle because I was expected to provide some responses to comments by an independent assesor (examinar). But it did not happen. The assesor reported, "No revision is needed". It was only suggestions in the letter. That made me so happy.
In fact, I am still working on the methodology, epistemology, ontology, and so forth. I used to be with critical realist's epistemology to interpretivist's one. I still do not understand how many epistemological options are available.
I just wonder about my research design and what scholars said at my confirmation, the doctoral workshop and the conference. My design aimed at achieving a theoretical replication logic but it was almost ignored by many scholars. They were more interested in just a comparative study. This indicates that not so many researchers understand what the case study really is. This scares me a bit.
