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 ...

The epidemiologic transition theory presented first by Omran [Omram. A. R. (1971) The epidemiologic transition: a theory of the epidemiology of population change, Mildbank Quarterly 49(4), 509-538] was designed to explain global trends in the dynamic relationship between epidemiological phenomena and demographic change. This paper argues that universalizing this theory only partially serves to ...

Demographic transition refers to the process whereby populations shift from regimes of high mortality and high fertility in approximate long-run equilibrium (zero population growth) to a new equilibrium at low levels of mortality and fertility. Most European and overseas European societies experienced such a transition between about 1870 and 1930. Formulation of theoretical explanations of the ...

Abstract Asia is now, predominantly, a continent of ‘low’ fertility—one the features Second Demographic Transition. Across continent, this feature our population has sprouted concern and anxiety, primarily expressed in macroeconomic terms. Low fertility directly linked to twin challenges aging stagnation/decline. We know, however, that maximizing human capital institutional reform much more eff...

Inspired by the historical English experience, we modify the Beckerian paradigm of fertility by incorporating costly, societal influence on contraception. Heterogeneous, generationallylinked households choose between “traditional” and “modern” contraception. The modern has a higher fixed but lower variable cost of averting childbirths. Initially the rich adopt the modern, which unleashes societ...

This paper presents an analysis of demographic transition based on the endogenous evolution of intergenerational transfers along an economy’s endogenous path of development. Two-period-lived agents belonging to overlapping generations choose optimally their desired levels of consumption and fertility, together with their desired sizes of transfers to both parents and children. Parents are more ...

This paper finds that fertility responds to productivity differently depending upon the economy’s stage of development. At low levels of development, productivity increases will increase fertility while at the more advanced stages of development, productivity increases lower fertility. During the process there may be important interaction effects between productivity and education demand. Incre...

BACKGROUND Declining rates of fertility and mortality are driving demographic transition in all regions of the world, leading to global population ageing and consequently changing patterns of global morbidity and mortality. Understanding sex-related health differences, recognising groups at risk of poor health and identifying determinants of poor health are therefore very important for both imp...
