stratification

a process in which certain seeds are subjected to low temperatures for a period of time, in order for GERMINATION to take place. Natural stratification occurs when seeds are shed in autumn and become covered with soil, leaves, etc. during the winter. The process can be reproduced artificially by alternating layers of seeds with layers of moistened substrate such as sphagnum moss and storing at a low temperature.

It is here that I accordingly propose speaking not of a "stratificational" retrieval, but of becoming lucidly aware of the usually anonymous moments "through-which" the experience ongoingly proceeds, appreciating them in their dynamic efficacy, "in-the-act", which is to say: not as "levels" in a static structural hierarchy, and not as pre-objective "stages" left behind on the way to object-constitution, but as dimensions still permeating the experience and continuing to function as living "Durchgang"-moments in the temporal ongoingness of a complex whole--as "intermediating" moments-"through"-which a phenomenon is given (23).
This model, applied to class research, reveals a clear hypothesis about the mechanism between linguistic use and stratificational outcomes which is close to Bernstein's (1975) theory of restricted and elaborate codes: Restricted, lower class linguistic code tends to correlate with simple and merely descriptive, short-sighted causal assumptions.
Set against the `behavioural and cultural linkage' in class theory, PW's `autonomisation' refers to the detachment of subjective orientations and behaviour from stratificational location.
Both formal and informal social networks produce respectable amounts of marginal improvement in the model and they affect, but do not wipe out the effects of, the original baseline variables: Social networks resources are not reducible to more accepted stratificational assets.
A number of trendy terms are glossed over so lightly as to be nugatory: stratificational, functional, Montague, generative semantics, daughter-dependency, etc.
