Abstract: The effects of the HIV/AIDS epidemic on fertility in Africa remains ill understood. To align the contrasting findings of recent empirical research, we develop a portfolio model that captures the potential trade-off between "quantity" and "quality" of offspring. According to this...

Abstract Abstract This paper empirically investigates the effect of fiscal decentralization on public safety, which is widely taken as an important issue in evaluating the performance of public service. In addition, we provide evidence to the transmission channels of the decentralization effect....

The mathematical expression of nonadditivity X(1 ∪ 2)=X(1) + X(2) + αX(1)X(2) has been frequently used for the development of statistical physics for nonadditive system, where X is entropy or energy, and α is hoped to be a parameter characterising the nonadditive property of the composite...

A simple model is presented to illustrate the equilibrium thermostatistics of a nonentensive finite system. Interaction between the finite system and the reservoir is taken into account as a nonextensive term λH1H2 in the expression of total energy (H1 and H2 are the energy of the finite system...

This paper develops a model, based on both properties of mixture and self-exciting, that generalizes existing software reliability models. We also offer a model classification method. Details are proven with some specific cases and examples illustrating the results are given.

In this paper, we have investigated the effects of adaptive cruise control (ACC) vehicles in a mixture with manually-controlled (manual) vehicles. The manual vehicles are simulated by using the modified comfortable driving model, which can describe synchronized traffic flow. The phase transition...

Deviation from simple power law is widely observed in complex networks. We introduce a model including possible mechanisms leading to the deviation. In this model, probabilistic addition of nodes and links, as well as rewiring of links are considered. Using master equation, through theoretical...
