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....

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...

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,...

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...

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...

In this paper, we propose a modified fitness evaluation mechanism, which integrates the environmental factors into the focal player’s fitness calculation, to investigate the evolution of cooperative behaviors in the prisoner’s dilemma game. Here, the fitness of a player is computed by...

We consider a kind of Collision Branching Processes with Immigration (CBIP). Some important properties of the generating functions for the CBI q-matrix were first investigated in detail. Then for any given CBI q-matrix, the existence and uniqueness of CBIP is proved, and sufficient and easily...

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...

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....
