The latter, variously characterized as "correspondence rules" or "coordinating definitions," relate the theoretical and observational vocabularies, and it is through them that theoretical terms acquire what meaning they have.
Nagel's first formal requirements was that the "laws" of the reduced theory must be derivable from the laws and associated coordinating definitions of the reducing theory.
But unless the division is wholly arbitrary, parsing theories thus into coordinating definitions and empirical statements assumes a principled difference in kind between the two categories of statements along the lines of an analytic-synthetic distinction.
For Carnap, as for Reichenbach, the choice of framework or coordinating definitions was conventional, a matter of convenience or heuristic fertility, whereas for committed Kuhnian normal scientists the foundational tenets of their paradigm are deep truths about the world, principles not subject to empirical test.
For ALK, the position on the horizontal axis (with the coordinate definition dominated by DFG related geometries) does not clearly mark them as active.
In addition, the existence and extent of nonequilibrium effects on the rate also depend on the reaction coordinate definition.
Two methods to register point clouds of industrial scenes with different coordinate definitions are presented.
The ISB standardization proposal was used for definition of the anatomical bony landmarks as well as the local coordinate definitions.
This is usually done by umbrella sampling calculations with a reaction coordinate involving the bond distances that define the chemical transformation (but other reaction coordinate definitions can also be used).
And if the only choice in theory choice is one among conventional coordinating definitions, then that is no choice at all, a point stressed by Reichenbach, especially, as an important positive implication of his position.
For y-coordinate definition see text and Fig. 3. Figure 12 Diffusion constants for acetic acid molecules in an equilibrated acetic acid water mixture in contact with α-quartz and calcite slabs as a function of the average molecular y-coordinate.
