Does Harding employ a sequential or concurrent data collection model?

When reading the article, Id like you to pay attention to and think about a few things:

In what sense is this a mixed methods study? How is Harding mixing both sources of data and analytic methods?
Is the motivation for using mixed methods in this case confirmatory or complementary?
Does Harding employ a sequential or concurrent data collection model?
Does Harding employ a nested or non-nested design?
