Empirical testing is needed to explore these linkages, determine whether they are bidirectional or unidirectional, and how they are influenced by contextual factors of disability.
Additionally, the simulations using mineralogical, reduced empirical flotation testing needed to develop the new flowsheet.
In designing a new network, a considerable amount of theoretical and empirical test data needs to be gathered, checked, and analyzed.
Direct empirical tests are needed to establish viability for use with Corvid species, oscines that diverged from the Passerida ~50 MYA.
Various quantitative genetic models have attempted to predict the constraints caused by gene flow under migration - selection balance [ 8, 9] but clearly more empirical tests are needed.
Modelling of data from the Health Survey for England indicated that active case-finding (with postal questionnaire plus opportunistic case-finding in primary care consultations) would be more effective than opportunistic case-finding alone, but this needs empirical testing [ 32].
As the CER framework and the learning progression derived from it have undergone extensive testing thereafter proved they are more effective comparing to traditional intervention (e.g., McNeill and Krajcik 2008, 2009; McNeill et al. 2006; Songer et al. 2009; Songer and Gotwals 2012), the hypothetical learning progression we propose also needs further empirical testing.
This classification may need refining and certainly needs much more empirical testing.
These observations further support the need for empirical testing of each Fabry disease-causing mutant form of α-Gal A to identify those that are responsive to AT1001.
The content of the negative comments was grouped into overarching themes of concern: since none of the professionals had prior experience with DT, their concerns were regarded as hypothetical, in need of empirical testing by patients.
