Most life history studies assume that demographic transition rates within a population are temporally and spatially invariant. A violation of these assumptions may have important consequences in the analysis of long-term processes such as population growth and stability. To examine the potential problems, I studied the demography of a size-classified population of Danthonia sericea, a long-live...

This is a study of how the combination of cultural and structural factors, which played a major role during the historical fertility and nuptiality transition, have continued to condition demographic innovations connected to the “second demographic transition”(SDT). The continuity or discontinuity from the “first” to the “second” demographic transition is studied for spatial aggregates over mor...

Successful economic development is usually characterized by two salient phenomena: industrialization and demographic transition. Chronologically both events happen so closely to each other that historians and economists alike suspect that they are interrelated. This paper develops a theory for their interaction with a special emphasis on the different pattern and pace of transition in cross-cou...

in this work, we report results of calculations based on the density functional theory of different species metal-ozone, containing mercury, silver and gold. the chosen species range from small molecules and large transition-metal containing ozone with mercury, silver and gold complexes. a comparative analysis of the description of the metal-oxygen bond obtained by different methodologies is pr...

molecular dynamics simulation has been performed to analyze the effect of the presence of gold nanoparticle on dynamics of kob-anderson binary lennard-jones (blj) mixture upon supercooling within the framework of the mode coupling theory of the dynamic glass transition. the presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution ...
