Coding
In order to code and analyse the content of the
articles, a list of 26 major themes of research
or keywords was developed. The creation of
this list was necessary because of the large
number of idiosyncratic keywords provided

among the near 1000 keywords retrieved from
authors and databases such as ABI/Informs,
a majority (more than 65%) were used only
once. Such a number is too large to be analysed,
and the fact that a large number of these
keywords were used only once would have
reduced the reliability of the analysis. Therefore,
we first developed an initial list of major
