there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
We contrast the concepts of computational simulation as practiced in computer assisted design with that of numerical modeling of geology and other observational sciences in which controlled experiments are not available. We highlight the role of the modeller in subjectively weighting observations, modelling and experience to find a preferred geological model.
[1] It has come to our attention that the constitutive relationship used in the modeling of geodynamical flow problems with strongly variable physical properties, should have additional terms in the stress tensor, known in the literature as Korteweg stresses (K-stresses). These stresses arising at diffuse interfaces, which can best be explained in terms of density gradients, have already been m...
