in this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4),  ferromagnetic ising system consisting of magnetic atoms with spin-1. this study is done using the effectivefield theory (eft) with correlations method. the equations are derived using...

In this article, in order to demonstrate the pragmatic elements of Rawls’s viewpoint, the developmental path of his A Theory of Justice shall first be investigated. This development has two phases: In the first phase, justice has an ethical-philosophical basis. In A Theory of Justice, this phase is specifically shown under the title of theory of justice. In the second phase, justice has no phil...

The goal of this paper is to address whether and how the changing family sizes of cohorts born before and after the demographic transition are associated with increasing schooling in Brazil. Multivariate analyses of nationally representative data demonstrate that, although a higher proportion of adolescents born after the demographic transition live in smaller families, they also suffer a great...

Demographic transition due to population aging is an emerging issue throughout the developing world, and especially in China, which has undergone demographic transition more rapidly than most industrial economies. This paper quantifies the distributional effects in the context of demographic transition using the integrated recursive dynamic computable general equilibrium (CGE) model with top-do...

This paper discusses emerging demographic patterns and its opportunities and challenges for India. It investigates the specificities in the demographic transition in terms of various demographic parameters and the lack of homogeneity in the transition across states in the country. It presents some opportunities that can arise from having demographic changes, particularly the demographic dividen...

this essay introduces a general theory of how societies change as a consequence of the changing composition of their members with respect to certain relevant and measurable characteristics. these characteristics can either change over the life course of individuals or from one generation to the next. while the former changes can be analytically identified and described by certain ageand duratio...

China has been an overachiever in the global process of demographic transition in the second half of the twentieth century. its mortality decline was unparalleled in human history among populations of significant size, consequently setting the stage for rapid population growth. in turn, rapid population growth laid the foundation for an unprecedented state intervention in birth control. China’s...

The effect of population growth and demographic transitionon economic developmenthas been well documented. The population growth in Iraqi Kurdistan is passing through a critical stage of demographic transition. It is, in fact, extremely likely that the region will fail to efficiently move through the demographic transition and will experience a long period in the demographic trap, i.e. the popu...
