The net reproduction rate and the type-reproduction number in multiregional demography
No full textIn order to study effects of migration on demographic changes of multiregional populations, multiregional population modelling is a useful traditional tool. Although multiregional mathematical demography has been extensively explored since the beginning of the 1970s, its key concept, the multiregional net reproduction rate, has been long neglected. In this review, we focus on a multiregional stable population system and elaborate the definition of the multiregional net reproduction rate. Next we introduce the type-reproduction number from mathematical epidemiology and show that it becomes a useful index to formulate a simple control relation for a multiregional population. Mathematical ideas presented here will help us to reconsider multiregional mathematical demography, which is a useful theoretical framework to study effects of interregional migration on population dynamics and composition.

Proceedings of IEEE., 58, 1568, (1970).""Author Institution: Research Institute of Electrical Communication, Tohoku UniversityThe usefulness of Raman spectroscopy, which is so far recognized as a complementary technique to infrared spectroscopy, can be extended to include various new fields which are unique to itself. The laser-Raman radar scheme detecting the Raman backscattered echoes has been and confirmed experimentally by the present , which is capable of measuring remotely the number density of molecular constituents as well as their species existing not only in the ordinary but also in the polluted atmosphere. This paper wishes to report the operational performance and the experimental results, so far obtained, of our laser-Raman radar as a completely single-ended system for the chemical analysis of the real atmosphere. An alternative method, which utilizes a frequency-tunable dye laser with high repetition rate of pulsed operation is also developed to investigate the resonance spectroscopic effects of a variety of molecules and atoms contained in the lower and upper atmosphere. These effects include the fluorescence and the resonance scatterings along with the resonance Raman scattering, and are expected to improve significantly the sensitivity and the range capability for the constituent analysis of our environmental air
