Method A systematic literature review methodology was adopted to find, evaluate, analyse, and synthesize literature in a transparent, replicable manner. Retrieved articles were categorized by the following topics: year of publication, journal name, whether from practice or academia, research methods employed, and country of residence of corresponding author, in order to establish trends in publications from 1970 to date. A series of keyword searches were conducted on electronic databases between May 2012 and July 2012. The literature obtained was evaluated against specified criteria for relevance and quality. Reference lists from articles that met the selection criteria were used to locate further literature; grey literature from other sources was also assessed against the specified criteria for relevance and quality.
