High-level theme map of 60% of the concepts in the first 40,000 words of ‘draft zero’ notes for my PhD project. Taken using Leximancer 3.5 software for content analysis. The project examines the evolution of strategic culture — a framework used in strategic studies, history and military sociology — in the sub-discipline of counter-terrorism studies. The full theme map has a more dense structure and sub-concepts. I discarded 80,000 words for another project and still have 65,000 words from written notes to analyse.
