Find an example of a published academic journal article that employs a non-doctrinal or mixed methodology. This might be a paper that is empirical, comparative, socio-legal, or which is multidisciplinary (e.g. law and economics, or law and political science). 

Critically discuss its methodology and findings, reflecting on how the methods used by the author(s) further our knowledge in ways that would not have been possible using only traditional doctrinal legal research methods
