In TIMSS, PIRLS and ICCS, the variance of the achievement scores explained by the explicit stratification is however only about 5% on average (source: own computations); this is why the models presented in this paper explain five to seven times higher portions of this variance.
Aiming to the achievement of low system height and satisfactory water temperature stratification, new types of ICS systems with two horizontal cylindrical storage tanks, properly mounted in stationary CPC reflector troughs are suggested.
In patients with established CVD and with target LDL-C level achievement, Lp(a) measurement may add addictive value for cardiovascular risk stratification.
Using a more forgiving yardstick to measure the achievements of those fortunate enough to attend elite colleges reinforces social stratification in exactly this way.
The class system, for the record, is a defined system of stratification based on economic position in which people are ranked based on achievements such as education and wealth.
From once separate systems with distinct stratification orders, commercial and academic standards for success have become integrated into a hybrid regime where achievement in one realm is dependent upon success in the other.
But it has also hopefully liberated conservatives to look back on the Reagan-Thatcher 1980s admiringly but unsentimentally: To see those leaders' immense virtues and great achievements plainly, but also to recognize the ways in which in many of today's challenges — economic stratification, cultural fragmentation, social disarray — are part of the warp and woof of their legacy as well.
In stratification and mobility research, the status attainment paradigm focused almost exclusively on the individual determinants of socioeconomic achievement, until the "new structuralism" maintained that structure is both more important than and logically prior to individual attainment (Kalleberg and Sørensen 1979).
The comparisons of four prognostic models according to the CR rate, early mortality rate and 3-year OS rate in four risk stratifications were listed in Figure 2. Figure 2a showed that all prognostic models can predict CR achievement.
"Cognitive stratification".
