Current attempts to create a unified, multidisciplinary cognitive science have languished. This paper demonstrates how the human-computer interaction (HCI) paradigm can serve as a unifying framework for cognitive science. HCI has focused the research of many disciplines on the single domain of interaction design. Cognitive science, in contrast, has emphasized multidisciplinary research across a...

One particle inclusive cross sections in the target fragmentation region are considered and an explicit calculation is performed in (3) 6 model eld theory. The collinear divergences can be correctly absorbed into a parton density and a fragmentation function but the renormalized cross section gets a large logarithmic correction as expected in a two scale regime. We nd that the coeecient of such...

Island biogeography theory (IBT) provides a basic conceptual model for understanding habitat fragmentation. Empirical studies of fragmented landscapes often reveal strong effects of fragment area and isolation on species richness, although other predictions of the theory, such as accelerated species turnover in fragments, have been tested less frequently. As predicted by IBT, biota in fragments...

The fragmentation process of primordial-gas cores during prestellar collapse is studied using three-dimensional nested-grid hydrodynamics. Starting from the initial central number density of nc ∼ 10 cm, we follow the evolution of rotating spherical cores up to the stellar density nc ≃ 10 cm. An initial condition of the cores is specified by three parameters: the ratios of the rotation and therm...

This paper describes the process of mechanically certifying a compiler with respect to the semantic speciication of the source and target languages. The proofs are performed in type theory using the Coq system. These proofs introduce speciic theoretical tools: fragmentation theorems and general induction principles. Un compilateur certiii pour un langage impratif RRsumm : Cet article ddcrit la ...

The production of the excited charmed baryon doublet Lc * via fragmentation is studied. An analysis of the subsequent hadronic decays of the doublet within the framework of heavy hadron chiral perturbation theory produces expressions for both the angular distribution of the decay products and the polarization of the final state heavy baryon in terms of various nonperturbative fragmentation para...

The production of various heavy-quark-containing baryons in electron-positron annihilation is considered. On the basis of exact formulas that we obtained previously within full perturbation theory, new numerical calculations of the respective cross sections are performed, and simple approximate expressions are then constructed for the results of these calculations. The dependence of the total c...

Purpose: To clarify the concept of fragmentation of chronic care and contribute to the international debate on how to reform systems to better address the needs of people with a chronic disorder. Theory: In a system wherein care of health and cure of disease get managed, differentiation or the division of work is its very essence and strength. If reducing differentiation is not a realistic opti...
