The study approach of this paper is to combine experiment and simulation on using butanol as fuel in gasoline engine. First, experiments were performed under full load on a single cylinder spark ignition engine fueled with 35%vol butanol–gasoline blend and the pure gasoline, respectively. The...

Based on a classical contact model, the spreading dynamics on scale-free networks is investigated by taking into account exponential preferentiality in both sending out and accepting processes. In order to reveal the macroscopic and microscopic dynamic features of the networks, the total...

This paper employs a non-parametric method to forecast high-frequency Canadian|US dollar exchange rate. The introduction of a microstructure variable, order flow, substantially improves the predictive power of both linear and non-linear models. The non-linear models outperform random walk and...

In this paper, a new robust and efficient estimation approach based on local modal regression is proposed for partially linear single-index models, of which the univariate nonparametric link function is approximated by local polynomial regression. The asymptotic normality of proposed estimators...

Purpose – This paper aims to understand how organizational and interpersonal relationships influence selling centers, and how to form an effective selling center to establish cooperation among the functional departments to satisfy customer needs. Design/methodology/approach – The selling...

Purpose – The purpose of this paper is to test the market‐based asset framework by examining the role of marketing process improvements in the relationship between a buyer firm's supplier‐related activities and its performance. Design/methodology/approach – Interviews with executives who...

Purpose This paper aims to reveal the global non-synchronism that exists in the theoretical research of information science (IS) by analyzing and comparing the distribution of theory use, creation and borrowing in four representative journals from the USA, the UK and China....

The purpose of this paper is to show how agent-based simulations of payment systems can be used to aid central bankers and payment system operators in thinking about the appropriate design of payment settlement systems to minimise risk and increase their efficiency. Banks, which we model as the...
