Hodges' model - Locus of Care & Control?

Draft notes:

There are obvious geometric features (Stewart, 1981) in Hodges’ model. Application of the model is a holistic affair. The centre of the model is its centre (as a template), but in application it is not fixed. There are several degrees of freedom, determined by the context of application. Consider figures 4a, 4b and 4c. Perhaps it can be argued there is what amounts to a care locus? As Persons (2025) notes:

‘Primary care is considered the first line of defense in health care, and it is the locus of the maintenance of both individual and population health.‘ p. 15.

 Emphasis can be placed on selected domains, as the situation dictates:
