The coastal-inland income gap in China from 1991 to 1999: the role of geography and policy
No full textWe investigate the enlarging coastal-inland income gap in China during the 1990s, using GMM estimation of a Solow growth model. Disaggregating capital investment by source: public, foreign and private: helps to disentangle the effect of policy from those of geography. The impact of public investment on growth is insignificant in our panel data for 29 provinces; that of foreign investment is significant; private investment is most influential. We also use the distance by railway of each province’s capital city to its nearest port city as a proxy for transportation costs, and find significant differences across regions. Distance has negative effects on economic development but its marginal impact effects become less as distance increases. The coastal-inland gap will grow in the foreseeable future, if inland areas are not able to benefit from an increase in private investment and infrastructure improvements (to reduce transport costs)
Turbulent structures in unsteady wall-bounded flow subject to temporal acceleration
No full textDirect numerical simulations (DNS) of a transient turbulent channel flow subject to constant temporal acceleration have been performed with a final Reynolds number of \Retau=800. The response of turbulent structures to the temporal acceleration is investigated. A significant delay in the response of turbulent flow is observed in various turbulent properties. It is found that the response of turbulent flow to temporal acceleration consists of two stages: the destruction of the initial \emph{old} turbulence, followed by the generation of \emph{new} turbulence associated with a higher number. The \emph{new} turbulence is much stronger than the \emph{old} turbulence

Mossbauer-effect study of nondimensional and 2-dimensional quasi-crystalline alloys in the Al-Pd-Fe system
No full textRoom temperature Fe-57 Mossbauer effect measurements of the one- and two-dimensional quasicrystalline phases of Al75Pd15Fe10 are reported. Both materials show Mossbauer spectra with asymmetric doublets which have been analyzed in terms of a distribution of quadrupole splittings, and in terms of a discrete expansion of quadrupole splittings. The one-dimensional material shows the following characteristics compared with the two-dimensional material; (1) a larger mean quadrupole splitting, (2) a more positive mean isomer shift and (3) a broader distribution of quadrupole splittings. These results indicate that the local Fe environments in the one-dimensional material are less isotropic than in the two-dimensional material and that this material is characterized by a higher concentration of open volume defects.PT: J; CR: DUNLAP RA, 1993, MAT SCI ENG R, V10, P141 DUNLAP RA, 1993, PHILOS MAG B, V67, P69 EIBSCHUTZ M, 1986, PHYS REV LETT, V56, P169 GUPTA A, 1989, PHYS REV B, V39, P8757 HE LX, 1988, PHYS REV LETT, V61, P1116 HESSE J, 1974, J PHYS E, V7, P526 LAWTHER DW, 1990, HYPERFINE INTERACT, V60, P785 LAWTHER DW, 1993, J NON-CRYST SOLIDS, V153, P49 LAWTHER DW, 1993, J NONCRYSTALLINE MAT, V154, P49 LAWTHER DW, 1994, PHYS REV B, V49, P3183 SRINIVAS V, 1989, PHYS REV B, V40, P9590 TSAI AP, 1992, PHIL MAG LETT, V66, P203 WANG Z, 1993, J PHYS-CONDENS MAT, V5, P663 ZHANG H, 1990, PHYS REV B, V41, P3482; NR: 14; TC: 0; J9: SOLID STATE COMMUN; PG: 3; GA: RA106Source type: Electronic(1
