To make a definite conclusion, analysis of the mesosphere data on vertical drift and IGWs is required.
This is in contradistinction to Russell (1905) whose definite description17 analysis of "proper" names requires a unique referent.
But on Russell's analysis, proper names such as "Zeus" in (13a) and "Sherlock Holmes" in (15a) are abbreviated definite descriptions and, given his analysis of definite descriptions, both (13a) and (15a) turn out to express false existentially quantified propositions (see section 5).
An influential attack on the situation semantics approach to "incomplete" definite descriptions came from Soames 1986, who concluded that "the analysis of definite descriptions is not facilitated by the kind of partiality that situation semantics provides" (Soames 1986, 368).
22 Analysis of definite and probable cases only and definite cases alone just failed to show equivalence: in the first case the upper bound of the 95.5% confidence interval around the point estimate of the cumulative incidence in the percutaneous group lay marginally above the 25% band and in the second case marginally below the band.
Yet, a definite confirmation requires the analysis of photon statistics, that is, measurement of the time distribution between photon pairs in a second-order correlation function, commonly known as a photon antibunching measurement (see Methods section).
This suggests that the analysis of definite descriptions is facilitated by the kind of partiality that situation semantics provides.
But according to Ludlow and Segal (2003), if we combine this pragmatic distinction with the unified analysis of definite and indefinite descriptions there is something we can say about this last bit of residue.
The requirement perhaps has more evident plausibility than the others but it plays no role in Quine's fully regimented theory because in that theory singular terms are eliminated by the technique of Russell's analysis of definite descriptions.
The question is whether each of these constructions must be treated in a different way, or whether it is possible to unify their treatment with the analysis of definite descriptions discussed above.
