Migration, unemployment dispersion and the Phillips curve

Regional Science and Urban Economics, 1980
Abstract Policy-makers have long known that the complexity of the labor market creates the potential for a wide variety of strategies to be utilized to improve the ‘wage inflation-unemployment’ trade-off. This research assesses the potential effect of two unemployment-reducing strategies — reducing the dispersion of unemployment rates and increasing ...

EXPERIMENTAL DISPERSION CURVES FOR PHONONS IN ALUMINUM

Solid State Communications, 1963
Abstract Dispersion curves for phonons propagating in the [100] and [110] directions in an aluminum crystal at ~ 300°K have been measured in a neutron scattering experiment. These data together with the elastic constants obtained by Schmunk and Smith yield dispersion curves having average random errors of ~0·6 per cent, and estimated total errors of ...

Phonon dispersion curves of bcc Ba

Physical Review B, 1985
Large single crystals of bcc Ba were grown and were used to study the lattice dynamics of this divalent metal by inelastic neutron scattering. The phonon dispersion curves were measured, at room temperature, along the (xi00), (xixi0), and (xixixi) symmetry directions.

An alternative method for plotting dispersion curves

Ultrasonics, 2009
Solving the frequency equation and plotting the dispersion curves in problems of wave propagation in cylinders and plates, particularly when the material is anisotropic, are complicated tasks. The traditional numerical methods are usually based on determination of the zeros of the frequency equation by using an iterative find-root algorithm.

Interpretation of phonon dispersion curves

Solid State Communications, 1963
Abstract The striking fact which has emerged from the experimental studies by neutron spectroscopy of alkali halides, covalent elements, and metals is the existence of long range forces in all three classes of solids. The concept of a force constant has never played a very important part in interpreting the results for alkali halides, since the ...

Phonon dispersion curves of CsCN

Pramana, 2004
The motivation for the present work was gained from the recent publication on phonon dispersion curves (PDCs) of CsCN from the neutron scattering technique. We have applied the extended three-body force shell model (ETSM) by incorporating the effect of coupling between the translation modes and the orientation of cyanide molecules for the description ...

Phonon dispersion curves for zinc

Journal of Physics C: Solid State Physics, 1969
Using a triple-axis neutron spectrometer all branches of the phonon dispersion curves along the three major axes of zinc have been measured. The results for the Δ and Σ axes are in fair agreement with those of previous workers. Results for the T, Tprime axes have not previously been reported.

Phonon dispersion curves of indium

Journal of Physics F: Metal Physics, 1981
Using the modified axially symmetric model with volume forces, the phonon frequencies of indium have been investigated. The lattice structure of indium has been treated as both BCT and FCT in order to avoid the confusion created in the past in understanding the crystallographic equivalence of these two lattices.

Phonon dispersion curves for niobium

Czechoslovak Journal of Physics, 1984
The experimentally measured phonon dispersion relation for niobium is very complex. This complexity may be due to the incomplete electronicd shells which make an important contribution to very large cohesive energy, and its likely effect on the phonon frequencies.
