The metamorphosis of Lewis’s dual economy model

This paper argues that Arthur Lewis originally presented the problem of economic development in terms of an open system, in the sense that it focused on a number of possible pitfalls and socio-economic constraints in the process of capital accumulation and industrialization in a labour-surplus economy. In the hands of the neoclassical economists, who were predominantly interested in achieving d...

Systematics of the first 2+ excitation in spherical nuclei with the Skryme quasiparticle random-phase approximation

We use the quasiparticle random-phase approximation (QRPA) and the Skyrme interactions SLy4 and SkM∗ to systematically calculate energies and transition strengths for the lowest 2+ state in spherical even-even nuclei. The SkM∗ functional, applied to 178 spherical nuclei between Z = 10 and 90, produces excitation energies that are on average 11% higher than experimental values, with residuals th...

General behavior of double beta decay amplitudes in the quasiparticle random phase approximation.

Simple formulae for the 0+ → 0+ double beta decay matrix elements, as a function of the particle-particle strength gpp, have been designed within the quasiparticle random phase approximation. The 2ν amplitude is a bilinear function of gpp, and all 0ν moments behave as ratios of a linear function and the square root of another linear function of gpp. It is suggested that these results are of gen...
