Nous proposons un nouveau cadre empirique qui permet de décomposer simultanément la variance conditionnelle des séries chronologiques de données économiques en deux facteurs : l’incertitude agrégée et l’incertitude sectorielle. Nous appliquons notre cadre à un vaste ensemble de données désagrégées relatives à la production industrielle aux États-Unis ...

Abstract On the basis of the variational method, approximate solutions f k ( r ) h k ( θ ) , f k ( r ) g k ( θ ) , F k ( θ ) H k ( r ) , F k ( θ ) G k ( r ) of the biharmonic equation are established for the circular sector with the following properties: The stress functions fkhk create shear tractions on the radial boundaries; the ...

The ion optics of sector and tandem sector mass spectrometers is a complex concern,integral to all their applications. This article provides an introduction to instrumental aspects and ion optics of sector mass spectrometers. The α2 aberration is derived as an example of the imperfections in first order ion optic theory, which affect the all-important ...

Sector Choice and Sector Regret
Nonprofit and Voluntary Sector Quarterly, 2019Although sector choice theory is improving, we have less understanding of how social entrepreneurs view their sector choices in hindsight, particularly given the various barriers to changing organizational form once a legal entity has been established.

Sector Bias and Sector Dualism
International Journal of Comparative Sociology, 2009There are several explanations for the inequality upswing in the literature: rising globalization, the institutional re-structuring of the nation-states, as well as changes in the relation between the demand for and the supply of skills. Concerning demand changes, Kuznets and Lewis identified two inequality affecting mechanisms with regard to the ...
