To explore into the process difficulty of knowledge work could further improve the efficiency of the knowledge work. A model of process difficulty of knowledge work was developed. Based on 188 questionnaires, the confirmatory factor analysis showed the process difficulty of knowledge work was influence by four factors: complexity, uncertainty, structure and ambiguity.
An image retrieval based on texture primitive is proposed in this paper. The texture primitive is firstly constructed according to the principle of the block truncation code (BTC). Meantime, based on the analysis of the statistical distribution of the texture primitive, the spatial distribution map of each feature is presented to describe the image texture information. Experimental results show that...

And the design idea, the system architecture as well as the realizing methods of the system are also introduced in detail.
In this paper, we investigate on the capital structure especially on the external finance source. We also try to find out the correlation between the leverage and the shareholder value creation. We focus our study on the corporate life cycle that is nowadays very used in finance work. The paper employs the comparative analysis and the statistical technique of Pearson's correlation analysis. We find...
A new image encryption scheme using the new compound chaos by selecting one of the two one-dimensional chaotic functions randomly is proposed and an image pixel permutation is described in detail, and the permutation method is the 3D baker scheme. In the scheme a new dynamic block dividing of the 3D baker scheme using the compound chaotic map is put forward. The properties of compound chaotic functions...
For reducing the economic losses of hydraulic generator units, fault detection and diagnosis is fundamental. A technique is presented that uses pattern recognition and cluster analysis. Faults of hydraulic generator units are classified from the characteristic parameters using statistical analysis methods. A characteristic parameter matrix of standard faults has been developed for identifying the...
Case based reasoning(CBR) is becoming widely used in computer aided process planning system. It requires a mechanism for retrieval of similar parts from a case database which in turn requires a method for case similarity measurement. This paper presents a new approach of stamped metal parts retrieval, which is based on the multi-feature combination and user's feedback. The stamped metal parts information...
As primary and effective form of tacit knowledge spillover, informal innovation network exerts tremendous effect on development of industrial cluster. This paper took informal innovation network in high-tech industrial cluster as research object, and attempted to identify the influential factors of informal innovation network and relationship between each factor by empirical study with clusters in...
This paper concludes 18 control right allocation patterns, and uses descriptive statistics and ANOVA of numerical descriptive statistics to find out that the best control right allocation pattern of Chinese Private Listed Companies with the highest corporate performance is pattern SbCMm.
A daily time series analysis is explored in the unobserved mutual fund trading behavior. A statistical state space approach is used to estimate the model. Algorithms are adopted for the computation of observation weights for forecasting based on state space models. The methodology is illustrated for daily CAPM model of China' stock mutual funds.
Hierarchy model of real estate investment risk is established. Through using triangular fuzzy numbers and analytic hierarchy process, we have evaluated the risk of real estate, and identified the risk factors for the overall impact on real estate investment project.
It is a key problem of making the environment and economy sustainable development plan to analyze and appraise the state of water environmental carrying capacity objectively. This paper, based on the water environmental carrying capacity definition, from eco-efficiency angle of the water resource and environment, put forward the index system of assessing water environmental carrying capacity. In order...
A public project evaluation approach from the perspectives of the stakeholders satisfaction and economic, social and environment impacts is proposed. The evaluation system of the stakeholders' satisfaction is comprised of the dimensions of stakeholders' information, expectation, actual perception, complaint and trust. The social, environmental and economic benefits and disbenefits of the project stakeholders...
The China's South-to-North Water Diversion Project is the largest water transfer project in the world which was paid more attentions on by thousands of peoples. The important task of project manager is to control project cost and duration. It is the most concerned question with the project managers which factors seriously affect the duration and cost. In order to study the problem, a questionnaire...
By adopting independent sample T-test and ANOVA analysis based on the field questionnaire data, this paper makes an empirical study of the differences between different poverty reduction models in rural China, in an attempt to compare the NGO- and government-led poverty reduction projects and identify the differences of the project management efficiency of the four major poverty reduction models,...
This paper mainly researches on the relationship between firm performance and the structure and levels of executive compensation. According to a statistic analysis of executive compensation of Chinese listed companies across industries, focused on an empirical analysis of firm performance and executive compensation of listed companies, the relationship between firm performance and executive compensation...
In the process of order fulfillment in build-to-order supply chain (BOSC), one of the most important problems in the corporations is how to improve the cost-effectiveness of BOSC while increase of customer satisfaction is achieved. Meanwhile, the explosion of e-business, especially the Internet-enabled supply chain mode, makes it more cost-effective for manufacturer and customers to interact with...
Accurate and efficient network traffic classification is an important network management task. Two way messages in a session follow the underlying application protocol to exchange information. In this paper, we propose a novel application classification method based on message statistics, concisely representing the protocols' unique characteristics. We present algorithms using SVD-based and information...
The aim of the study is to determine the influence of health status on labor force supply in Chinese people aged over 20. We estimate the average treatment effect on labor force participation of health status using the Chinese Health and Family Life Survey (CHFLS) data of 3821 individuals. A concern when estimating the effect of health on labor supply is that health (especially self assessed health)...
It is significant to appraise service quality of logistics enterprises. In this paper, based on analysis impact factors for service quality of logistics enterprises, we proposed a set of assessment indexes, given the method of determining the assessment indexes weights using fuzzy AHP, and put forth a comprehensive assessment model based on TOPSIS. Finally, a numerical example shows that the method...
