The theory that birds evolved from a group of small terrestrial theropod dinosaurs has created much controversy. One argument proposed against this theory is that the lungs of early theropods were incapable of sustaining endothermic gas exchange requirements and could not have given rise to the lungs of birds. A reexamination of the comparative physiological and morphological literature combine...

This study explores the resource dependency and relational exchange theories of understanding firms’ participation in e-procurement, and seeks to determine the degree to which the resource dependency theory variables — supply importance, supply complexity, supply market dynamism, and availability of alternatives — affect information exchange and operational linkages, the relational exchange the...

An analysis of the baryon-baryon potential from the point of view of large-N c QCD is performed. A comparison is made between the N c-scaling behavior directly obtained from an analysis at the quark-gluon level to the N c-scaling of the potential for a generic hadronic field theory in which it arises via meson exchanges and for which the parameters of the theory are given by their canonical lar...

in this paper, we discuss the ways that communication accommodation theory (cat) can be a useful framework for understanding and diagnosing interactional issues in interpersonal and intergroup conflict situations. we argue that the theory’s construct of attuning strategies provides a multidimensional view of mutual adjustment, leading to insights relevant to successful versus unsuccessful confl...

This thesis is about conceptualizing relationship alignment in small firm relationships from an information exchange perspective. The thesis has a theoretical focus but is also informed by three case studies. The thesis is based on five papers dealing with information exchange with different focus: inter-organizational information systems, information exchange patterns, social information excha...

In the glorious decade running from 1871 to 1881, Jevons, Walras, and Edgeworth laid the foundations of most modern microeconomic analysis: in his Theory of Political Economy (1 edition 1871, 2 edition 1879; henceforth TPE ), not only did Jevons formalise for the …rst time, by means of his celebrated "equations of exchange", the conditions de…ning the equilibrium of a pure-exchange two-commodit...

Recently we have proposed the extended constrainedsearch sECSd theory in which arbitrary physical quantities can be chosen as basic variables in addition to the electron density.1,2 The validity of this theory has been confirmed by revisiting on the basis of it the spin-density functional theory sSDFTd, the current-density functional theory sCDFTd, the LDA+U method, and the Hartree–Fock–Kohn–Sh...
