At first, we analyze the advantages about employing multilevel model in communication research. When it samples from different levels and units, the resultant data will appear stratification. Hierarchical data structure is common in communication studies. Audiences exist within hierarchies tend to be more similar to each other than people randomly sampled from the entire population. Therefore, multilevel...
The theoretical calculation model for price-earning ratio (PE) is deduced through transforming the dividend discount model so as to find out the main factors affecting price-earning ratio in theory. Stocks of Shanghai Stock Exchange (SSE) 180 index are selected as the sample, and empirical study on the main factors affecting price-earning ratio is carried out based on the panel data during the 2005–2008...
Focusing on the “passion at work” specific to leaders, this study examined the relationships among leaders' passion at work, transformational leadership and leader effectiveness using structural equation modeling. Specifically, we developed and tested the ideas that mediated effects of transformational leadership. Using a sample of managers in China, results supported the direct and indirect effects...
Workflow simulation is a valid technique backing up process improvement. To this day, workflow model simulation is still a weak segment. Based on the research on workflow simulation technique, this issue carries out a way of business process simulation based on workflow, and offers the realization of workflow simulation mechanism supporting business process based on virtual running environment, finds...
Forecasting accuracy can be substantially improved through the combination of multiple individual forecasts. Yet most previous attempts at combining forecasts have focused on a single objective. This paper provides an ensemble forecasting model integrating autoregressive integrated moving average (ARIMA) with artificial neural networks (ANN) based on combined objectives. Golden section criteria is...
With the development of computer technology and geological modeling study of the gradual maturity, 3D for the engineering geological modeling and information visualization analysis system of opportunities and challenges brought about. Have carried on the detailed introduction to the three dimensional geological modeling tool and the method. Summarized the three dimensional geological modeling basic...
Railway, as one of the most essential infrastructures of China, has endured extremely high difficulty level due to huge investment scale and high quality requirements. The traditional management method of technical-economic indexes and simulation are not perfect, so simulating technical indexes catering to the features of railway construction project is an accurate and efficient management method...
The paper analysed the efficiency of logistics industry in 31 provinces of China in 2009 by three-stage DEA model. The empirical results are as follows: firstly, the technical efficiency of 31 provinces is low, with the average of 0. 468, and the reason is the lack of scale efficiency; secondly, the development of logistics industry in East, Central and West of China differs wildly, specifically speaking,...
In this paper, the nonlinear operating performance of the valve regulated lead acid (VRLA) battery is investigated, and a comprehensive battery model is established based on 2nd-order Randle model and ampere-hour counting concept; then a multidimensional system states estimation method is proposed based on sigma point Kalman filter (SPKF), and battery state of charge (SOC) is included in the states;...
At present, the research on evaluation of urban traffic level of service (LOS) mainly aims at the basic road section and intersection. However, it still lacks unified evaluation index and practical approach. Therefore, in this paper, we propose a method that the regional traffic LOS is evaluated by adaptive neuro-fuzzy inference system (ANFIS). ANFIS is used to emulate human's expertise on specifying...
This paper constructs a dynamic stochastic general equilibrium model to analyze the behavior of the unobserved inflation target implicitly included in China's monetary policy in a New Keynesian framework. The empirical evidence suggests that the model is suitable for research on monetary policy and monetary business cycle. The results also support the assumption that China's monetary policy has a...
This paper presents a model of monitoring method in videos and imagines. In the case of a fixed camera, when moving object appears, all data indicating object movement will change greatly. The real moving target will be detected after processing the data which larger change. The accuracy and instantaneity of will be tested by MATLAB stimulation.
To evaluate the effectiveness of smart grid, a new interval number fuzzy multiple attribute decision-making model based on TOPSIS and interval fuzzy theory is presented, which adapts the fuzzy AHP and interval number theory to characterize the advantages and weaknesses in the construction of smart grid, and by applying the Hausdorff distance, the relative closeness of each alternative to ideal solution...
The dynamic relationship among investment, capacity utiliztion and consumer demand is discussed in this paper, using data from 28 Chinese manufacturing industries combined with vector auto regression model. Based on the generalized method of moments (GMM) estimation to get parameter values of panel VAR model, We find that response of investment to capacity utilization is positive by using impulse...
Through empirical study, this paper tests the effect of member age of the board of directors and independent characteristics on corporate performance from 863 listed companies of Japan, and the result shows that average member age of the board of directors and corporate performance are significantly positively correlated, independent director system is advantageous in improving corporate performance,...
As an important macroeconomic variable, exchange rate has a huge impact on international trade. This paper selects monthly total export data from 1996 to 2009 as sample data to make an analysis on the effects of RMB exchange rate volatility on China's exports. In order to make a comparison, this paper also selects China's exports to the United States as samples to study the effects of RMB exchange...
Based on China's provincial panel data from 1996 to 2006, this paper investigates into the factors affecting China's housing price-to-income ratio. It is concluded that: Both growth rate of per capita GDP and working structure ratio affects housing price-to-income ratio positively while the increase of household garbage treatment ratio promotes housing price-to-income ratio as a whole, and that education...
That is a good way that use the ARCH family models to describe the time-varying characteristic of the return sequence on stocks. Intuitively, the influence to present from the long history data should not bigger than the short history data. So the order restriction to the parameter is according to the fact better. This paper researched the maximum likelihood estimator (MLE) of the parameters in the...
In recent years, research for bank efficiency has became a most important topic of financial industry and regulatory authorities. China's banking industry has experienced large-scale shareholding reform since 2003, and has gone through the global financial crisis began in 2008, now it is facing the challenges and competition from opening-door policy in banking business. Under this background, this...
