[1] To be clear, although it is not acknowledged here, Doran's distinction between nuclearity (nuclear dependency) and linearity (linear dependency) actually draws on Martin's notion of orbital structure:
Doran's nuclear dependency corresponds to the relation between nucleus and satellite (e.g. Thing and Epithet) in Martin's model, whereas his linear dependency corresponds to the relation between satellite and satellite (e.g. Classifier and Classifier).
As previously explained, Martin's orbital model misconstrues experiential structure as a hypotactic logical structure, with nucleus as dominant and satellite as dependent. So Doran's model continues this misapplication of hypotaxis to a multivariate structure. However, Doran compounds the error by proposing two different types of structure within the same structure:
- nuclear dependency: Thing–Epithet
- linear dependency: Classifier–Classifier
