DETERMINANTS OF THE INITIAL DECISIONS BY JAPANESE FIRMSTO UNDERTAKE FOREIGN DIRECT INVESTMENT

This paper investigates the empirical determinants of the initial FDI entry decisions by Japanese firms to enter into the U.S and Taiwanese markets. The study is based on a full-sample survey of firms listed on Japanese stock exchanges and is for the period 1976-2000. We find that a number of macro/financial as well as micro (company-specific) variables are highly significant in explaining the observed entry pattern.Japanese foreign direct investment

Identification of Charged Particles by Multiplying Circuit

A pulse multiplying circuit for charged particle identification according to (E+E₀+k·dE/dx)×dE/dx E₀, k : const was made, in which a squaring circuit using eighteen diodes was devised. The E and dE/dx pulses, due to the incidence of charged particles, were given by a semiconductor detector and a proportional counter of gas flow type, respectively. The charged particles of low energies from D+d, T+d, Li+d and Be+d nuclear reactions were sorted by this circuit. A test for carbon ions was also done. The apparent separation ratios were as follows : ρ : τ : α : C≈1 : 2 : 9 : 6

Theoretical study of NMR relaxation due to rattling phonons

We calculate the NMR relaxation rate due to quadrupolar coupling of the nucleus to a local, strongly anharmonic phonon mode. As a model potential for a rattling motion we consider a square-well potential. We calculate the free phonon Green's function analytically and derive the low and high temperature limits of the NMR relaxation rate. It is shown that the temperature dependence of the NMR relaxation rate possesses a peak in contrast to harmonic phonons but in qualitative agreement with a recent NMR study on KOs2O6. We discuss the influence of phonon renormalization due to electron-phonon interaction.Comment: 5 pages, 3 figures, SNS2007 (Sendai, Japan) conference proceedings, accepted for publicatio
