It is shown that such determinations are most often implicitly informed by scientists individual perspectives on the hierarchical relations between various elements of the theory and the problem at hand. In addition to this main result, it is suggested that Wolfgang Paulis neutrino idea may well have been an adaptation of Ernst Rutherfords original and older neutron idea, which would provide evidence that the adaptation of older ideas is a more common practice than is often thought.&lt;/p&gt;</style></abstract></record></records></xml>
