Which Characters of Knowledge-Based Employees Have Higher Turnover Intension in Chinese Culture Industry?  [PDF]
Jing’an Chen
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.29004

By use of multiple logistic regression analysis of the questionnaire data of 465 knowledge-based staff in the culture industry of a province in the Western China, the author has found that the three main factors related to job satisfaction and the turnover intention are not simply negatively correlative, which differs from the former classical studies of relationship between job satisfaction and turnover intention. This research has discovered that 1) the factor of career development satisfaction is not predictable on the turnover intention probability; 2) the turnover intention of the knowledge-based staff who have low satisfaction with the job itself is not higher than those who have high satisfaction with their jobs; 3) the turnover intention of the staff with low pay satisfaction is lower than those with high pay satisfaction, that is, the knowledge-based employees with higher pay satisfaction have correspondingly higher probability of turnover intention, compared with those with lower pay satisfaction; 4) such covariates as gender, age, educational background, professional title, income level, position, working years, the number of previous work units being considered, all mentioned demographic characteristics above but the income level have no significant influence on turnover intention; the employees with low income levels are more unwilling to leave than those with higher monthly income level.

Abstract: The fourth-party logistics (4PL) based on resource sharing pattern is inevitable trend, so the implementation of Cainiao Logistics Plan has aroused the discussion of whether the development of 4PL will make resource sharing pattern popular in logistics industry. The purpose of this study is to investigate the profit model of 4PL represented by the Cainiao. So what kind of role does Cainiao play? Is the profit model sustainable? The research is based on single case study of Cainiao Logistics, which can be considered as a best practice when it comes to 4PL competition. The results identify the main aspects that explain why Cainiao will be efficient. It found that Cainiao not only created new ecosystem of E-commerce, but integrated most resources available in the supply chain.
Threshold strategy to improve the images reconstructed by electrical impedance tomography  [PDF]
Xiaoyan Chen, Jing Zhang
Journal of Biosciences and Medicines (JBM) , 2013, DOI: 10.4236/jbm.2013.12008

Because of the illposedness of soft field, the quality of EIT images is not satisfied as expected. This paper puts forward a threshold strategy to decrease the artifacts in the reconstructed images by modifying the solutions of inverse problem. Threshold strategy is a kind of post processing method with merits of easy, direct and efficient. Reconstructed by Gauss-Newton algorithm, the simulation image’s quality is improved evidently. We take two performance targets, image reconstruction error and correlation coefficient, to evaluate the improvement. The images and the data show that threshold strategy is effective and achievable.

Abstract: The paper presents a description of the experience of the nursing for the Pseudomonas aeruginosa pneumonia patient with partial laryngectomy. The nursing of Pseudomonas aeruginosa pneumonia, conscious disturbance, electrolyte disorder, affection supports and mental nursing was provided in the process of the postoperative treatment. Our experience may provide useful insight for the nursing of laryngectomy patients secondary to pneumonia with conscious disturbance. A deeper knowledge about improving the quality of clinic special nursing for the partial or total laryngectomy patient is necessary, with the development of modern medical technologies and medicine.
Canadian Lung Cancer Relative Risk from Radon Exposure for Short Periods in Childhood Compared to a Lifetime
Jing Chen
International Journal of Environmental Research and Public Health , 2013, DOI: 10.3390/ijerph10051916
Abstract: Long-term exposure to elevated indoor radon concentrations has been determined to be the second leading cause of lung cancer in adults after tobacco smoking. With the establishment of a National Radon Program in Canada in 2007 thousands of homes across the country have been tested for radon. Although the vast majority of people are exposed to low or moderate radon concentrations; from time to time; there are homes found with very high concentrations of radon. Among those living in homes with very high radon concentrations, it is typically parents of young children that demonstrate a great deal of concern. They want to know the equivalent risk in terms of the lifetime relative risk of developing lung cancer when a child has lived in a home with high radon for a few years. An answer to this question of risk equivalency is proposed in this paper. The results demonstrate clearly that the higher the radon concentration; the sooner remedial measures should be undertaken; as recommended by Health Canada in the Canadian radon guideline.
The Physical Foundation of Human Mind and a New Theory of Investment
Jing Chen
Mathematics , 2005,
Abstract: This paper consists of two parts. In the first part, we develop a new information theory, in which it is not a coincidence that information and physical entropy share the same mathematical formula. It is an adaptation of mind to help search for resources. We then show that psychological patterns either reflect the constraints of physical laws or are evolutionary adaptations to efficiently process information and to increase the chance of survival in the environment of our evolutionary past. In the second part, we demonstrate that the new information theory provides the foundation to understand market behavior. One fundamental result from the information theory is that information is costly. In general, information with higher value is more costly. Another fundamental result from the information theory is that the amount of information one can receive is the amount of information generated minus equivocation. The level of equivocation, which is the measure of information asymmetry, is determined by the correlation between the source of information and the receiver of information. In general, how much information one can receive depends on the background knowledge of the receiver. The difference in cost different investors are willing to pay for information and the difference in background knowledge about a particular information causes the heterogeneity in information processing by the investment public, which is the main reason of the price and volume patterns observed in the market. Many assumptions in some of the recent models on behavioral finance can be derived naturally from this theory.
Study on the Carbon Emission Reduction Performance of Resource Tax Reform: Based on the Perspective of Substitution of Factors of Production  [PDF]
Jing Chen
Open Journal of Business and Management (OJBM) , 2017, DOI: 10.4236/ojbm.2017.51017
Abstract: Resource tax is an important means to regulate energy consumption. Recent years, in order to alleviate the structural contradiction of supply and demand of energy in our country, the resource tax rate was adjusted repeatedly. This paper introduced energy factor into the production function model, using 2003-2011 industry panel data to estimate the degree of influence of the adjustment of the resource tax rate to the factor input structure and the production efficiency of resource consuming industries. Through empirical research, the following conclusions can be drawn: 1) The increasing resource tax accounted for the proportion of the total tax will prompt the resource consumption industries for re-allocation of production factors and capital and human resources elements will replace energy factor. This is conducive to optimize the structure of production factors, so as to promote the industry to improve production efficiency. 2) In high energy consumption industry, the substitution effect of capital factor on energy factor is more significant than the substitution effect of labor factor on energy factor; however, in low energy consumption industry, the substitution effect of labor on energy factor is more significant than capital elements’ substitution effect. 3) Compared with non-resource production industry, the impact of increasing the rate of resource tax on resource production industry mainly occurs as the alternative of labor actor for energy actor, and the substitution effect of capital is not significant.

Qiang Xu, Jing Li, Jianyun Chen
Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.34036
Abstract: Damage reliability analysis is an emerging field of structural engineering which is very significant in structures of great importance like arch dams, large concrete gravity dams etc. The research objective is to design and construct an improved method for damage reliability analysis for concrete gravity dam. Firstly, pseudo excitation method and Mazar damage model were used to analyze how to calculate damage expected value excited by random seismic loading and deterministic static load on the condition that initial elastic modulus was deterministic. Moreover, response surface method was improved from the aspects of the regression of sample points, the selection of experimental points, the determined method of weight matrix and the calculation method of checking point respectively. Then, the above method was used to analyze guarantee rate of damage expected value excited by random seismic loading and deterministic static load on the condition that initial elastic modulus was random. Finally, a test example was given to verify and analyze the convergence and stability of this method. Compared with other conventional algorithm, this method has some strong points: this algorithm has good convergence and stability and greatly enhances calculation efficiency and the storage efficiency. From what has been analyzed, we find that damage expected value is insensitive to the randomness of initial elastic modulus so we can neglect the randomness of initial elastic modulus in some extent when we calculate damage expected value.
Motor Learning Based on the Cooperation of Cerebellum and Basal Ganglia for a Self-Balancing Two-Wheeled Robot  [PDF]
Xiaogang Ruan, Jing Chen, Lizhen Dai
Intelligent Control and Automation (ICA) , 2011, DOI: 10.4236/ica.2011.23026
Abstract: A novel motor learning method is present based on the cooperation of the cerebellum and basal ganglia for the behavior learning of agent. The motor learning method derives from the principle of CNS and operant learning mechanism and it depends on the interactions between the basal ganglia and cerebellum. The whole learning system is composed of evaluation mechanism, action selection mechanism, tropism mechanism. The learning signals come from not only the Inferior Olive but also the Substantia Nigra in the beginning. The speed of learning is increased as well as the failure time is reduced with the cerebellum as a supervisor. Convergence can be guaranteed in the sense of entropy. With the proposed motor learning method, a motor learning system for the self-balancing two-wheeled robot has been built using the RBF neural networks as the actor and evaluation function approximator. The simulation experiments showed that the proposed motor learning system achieved a better learning effect, so the motor learning based on the coordination of cerebellum and basal ganglia is effective.
