We use these minimal assumptions, since a specific functional connection between the differentiation and re-specification rates and growth conditions is presently unknown.
Molina, M. D., Salo, E. & Cebria, F. The BMP pathway is essential for re-specification and maintenance of the dorsoventral axis in regenerating and intact planarians.
Abstract relationships allow not only the representation of dynamic interaction but also the re-specification of these systems through behavior adaptations.
Adjustments for structural model re-specification were guided by statistical considerations, previous literature, and theory.
Indexes exist to identify variables that are worth the effort of re-specification.
If even the desideratum of practical coherence is subject to such re-specification, then this holistic possibility really does represent an alternative to commensuration, as the deliberator, and not some coherence standard, retains reflective sovereignty (Richardson 1994, sec. 26).
We then carried out post hoc re-specification of the best fitting factor structures, adding three error covariance terms (items 1 2, 4 5 and 17 19), based on modification indices and semantic similarity between items, to yield model 6.
It could result from a re-specification of the entire system by explicit inclusion in the equations of the factors inducing cross-correlations among input-output technical coefficients, and subsequently applying computational methods that avoid simultaneity effects.
Moreover, in order to improve the fit of the three structural models to empirical data, some variables (and the related paths and parameters) that were worth the effort of re-specification were withdrawn according to indexes of modification (e.g., standardized residues of the covariance matrix).
