These discussions are primarily focusing on good practice in each and every step in the testing cycle, including, for instance, test specifications, item writing, test administration, marking, reporting test results, and post hoc test data analyses.
The framework of presheaves leads naturally to a configuration language that expresses structuring from instances of specifications, and also incorporates a new notion of instance reduction to extract the component instances from a particular configuration.
In many instances, compendial specifications do not exist for certain medium ingredients.
For instance, system specification serves essentially two different purposes: capturing the system functionality and forming the basis for design and implementation.
It is not just that one stage or step coincides with another (for instance, the specification of policy alternatives may interface with the selection of policy instruments/interventions).
It is currently unknown whether these cells express ALDH isoenzyme(s) with no or low affinity for the Aldefluor substrate, or with no or low overall ALDH activity, or represent a subpopulation of cells that have switched ALDH activity owing to, for instance, lineage specification or commitment.
In some instances, the specification of variables changed within the review.
This makes the estimates less vulnerable for functional form assumptions, for instance, about the specification of age.
