An intensive rescue strategy included system modifications, relaxation of data validity rules, close engagement with software vendors, and provision of intensive on-site user support.
Data modeling can be a part of the experimental design, but it only focuses on the structure and validity rules of the research data that need to be stored.
In September 2010, Business Roundtable and the U.S. Chamber of Commerce challenged the validity of Rule 14a-11.
A chest CT-based approach has now replaced the gold standard pulmonary angiography with equivalent clinical validity to rule out PE [ 27].
We saw that Hart tried to base the normative force of law on rules of recognition, which provide shared tests of validity for rules of the system.
To develop a rule-based scheme for characterization of "frailty", for instance, Fried et al. [ 16] first developed a conceptual framework, devised a rule-based system within this framework, and then validated the predictive validity of the rule-based system using survival data from the Cardiovascular Health Study.
As for STAT1, GBP1, and PSMB9/LMP2, the validity of the rule 'PLCG2 high in RA' was emphasized by its appearance in three independently established rule sets (rule set 'Berlin', position 5; rule set 'Jena', position 14; rule set 'Total', position 4; see Table 5 and Additional file 4).
As for STAT1 and GBP1, the validity of the rule 'PSMB9 high in RA' is emphasized by the fact that it appears in three different rule sets (rule set 'Berlin', position 13; rule set 'Leipzig', position 17; rule set 'Total', position 1; see Table 5 and Additional file 4).
It is to argue against the validity of the rule itself.
In this paper the validity of this rule of thumb is evaluated by an experimental and a numerical study.
