An example of linking from a theoretical concept to relevant
examples
You might be interested in doing a case study of participation in decision making, and search the main database with the key word 'participation'. This search finds several records, each of which has its key words listed near the top of the record. You notice that several of these records have the key word 'education', several have the key word 'welfare', and several have the key word 'feminism'.
There are now three ways you can develop your inquiry.
Some of the records you get from this search will be about participation
as a general citizenship concern, and may be quite theoretical. If you find
the theory too difficult, you could go to the Dictionary and read the entry
on 'participation' to get an introduction to this concept, before going on
with your original planned research.
Because you have noticed that several of these records refer to education, and others to welfare, you might decide to make one of these two areas your case study for examining how participation operates in practice. You could work with the records you have already got, and if necessary you could find out more about these two areas by doing new searches on 'education' and 'welfare'. You could then pick whichever of these areas gave you the more useful collection of material.
Because you have noticed that several of the records from your original search have the key word 'feminism', you might decide to explore participation in education and welfare from a feminist perspective. This would be a change from your original plan to do a case study of just one area, but the search results have given you a new idea about how to pursue your research.
