We investigate the evolution of cooperative behaviors with increasing neighborhood size on diluted lattices. For three typical pairwise game models which include prisoner’s dilemma, snowdrift and stag hunt games, all numerical results indicate that cooperation can persist or emerge around the...

It is well-known that individual diversity is a typical feature within the collective population. To model this kind of characteristics, we propose an evolutionary model of public goods game with two types of players (named as A and B), where players are located on the sites of a square lattice...

This study implies the causality-in-variance test newly developed by Hafner and Herwartz (2006) to investigate the volatility spillovers between domestic equity and bond markets in the G7 and BRICS countries. The empirical result shows that there is ethier unidirectional or bidirectional...

The aim of this paper is to analyze the role of renewable energy technologies (RETs) such as biogas, improved cooking stoves (ICSs), micro hydro (MH) and solar power (SP) in helping rural communities in Nepal to adapt to climate change. The analysis considers the energy efficiency of different...

Venture capital cannot only promote technological innovation and the development of high-tech industries, but also makes contribution to economic growth. Having a good reputation as the "Silicon Valley in Middle East", Israel is one of the most successful countries in developing venture capital....

For the purpose of comparison between several independent populations, many procedures exist for testing equality of means or medians among the groups. However, the mean or the median do not determine the entire distribution. This paper addresses the problem of testing the equality of quantiles...

Rhamnolipid biosurfactant, as an addition to rice straw hydrolysis bioprocess, could not only stimulate the hydrolysis rate, but also reduce the requirement for large amount of cellulases and promote its recycling process. In this article, through the observation of the changes of cellulases,...

Purpose – The aim of this paper is to examine how informed traders, i.e. transient institutional investors that actively trade on information to maximize investment profits, use insider trading signals in addition to accounting numbers to mitigate future abnormal returns....

To study the equality of several normal means when the variances are unknown and unequal, we propose a fiducial based test, and theoretically examine the frequentist property of the proposed test. We numerically compare the performance of the proposed approach with several tests, recently...

In this paper, we analyze differences in per capita carbon dioxide emissions from 1996 to 2010 in six sectors across 28 provinces in China and examine the σ-convergence, stochastic convergence and β-convergence of these emissions. We also investigate the factors that impact the convergence of...
