Instead of viewing the sciences as directed at large generalizations, they suggested that researchers offer a patchwork of models, successful in different respects and to different degrees at characterizing the behaviour of bits and pieces of the natural world.
We are confronted with a patchwork of models, all of which hold ceteris paribus in their specific domains of applicability (see also the papers collected in Falkenburg and Muschik 1998).
In case of the LEE this may be the result of a recurrent loss and acquisition of genes (patchwork model), or of a loss of parts of the locus by deletion events subsequent to its primary acquisition as an entity [49].
Almost certainly the ingenious Jun Takahashi had something fun in mind when he opened Undercover with a parade of models in patchwork bikinis, tromping in a kind of clog espadrille, and then lemony dresses creased in the pattern of a spider's web.
More and more data suggest that substrate ambiguity, first defined in the classical patchwork model of Jensen [ 8], rather than catalytic promiscuity [ 9], is the main road which facilitates divergence of most enzyme families [ 10, 11].
The provinces/territories were not, however, required to invest matching funds, as they had been under CAP and were free to select from a broad menu of early learning and care programs and funding models, perpetuating the patchwork of provision.
But there are no laws that cover animals as wards, so the patchwork of rescue groups that operate under a guardianship model have little legal foundation to protect the animals' interest.
Companies that want to fly drones won't need to worry about the patchwork of local laws, because those laws can be incorporated in the market-clearing computer model.
Two remarkable examples are validation of the patchwork model for metabolic system evolution and reconstruction of the phylogenetic relations of metabolic pathways.
A currently favored model, the patchwork model [9,10], proposes that pathways evolve from a system of enzymes with a broad substrate specificity to enzymes with specialized functions through gene duplications.
As explained in [ 30], an example in favor of the so-called patchwork evolution model is the Urea Cycle, which, in terrestrial animals, clearly evolved by adding a new enzyme, Arginase, to a set of four enzymes previously involved in the biosynthesis of Arginine[ 31].
