Mood States Recognition of Rowing Athletes Based on Multi-Physiological Signals Using PSO-SVM  [PDF]
Jing Wang, Pei Lei, Kun Wang, Lijuan Mao, Xinyu Chai
E-Health Telecommunication Systems and Networks (ETSN) , 2014, DOI: 10.4236/etsn.2014.32002
Abstract:

Athletes have various emotions before competition, and mood states have impact on the competi- tion results. Recognition of athletes’ mood states could help athletes to have better adjustment before competition, which is significant to competition achievements. In this paper, physiological signals of female rowing athletes in pre- and post-competition were collected. Based on the multi-physiological signals related to pre- and post-competition, such as heart rate and respiration rate, features were extracted which had been subtracted the emotion baseline. Then the particle swarm optimization (PSO) was adopted to optimize the feature selection from the feature set, and combined with the least squares support vector machine (LS-SVM) classifier. Positive mood states and negative mood states were classified by the LS-SVM with PSO feature optimization. The results showed that the classification accuracy by the LS-SVM algorithm combined with PSO and baseline subtraction was better than the condition without baseline subtraction. The combination can contribute to good classification of mood states of rowing athletes, and would be informative to psychological adjustment of athletes.

The Analysis of Antoinette’s Tragic Fate in Wide Sargasso Sea  [PDF]

Impact of Gender and Working Environment on the Level of State Anxiety among Primary and Middle school Teachers in China  [PDF]
Lijuan Wang, Dajun Zhang
Journal of Behavioral and Brain Science (JBBS) , 2012, DOI: 10.4236/jbbs.2012.21012
Abstract: State anxiety has become serious among primary and middle school teachers in China. By using stratified random sampling, we selected 2790 primary and middle school teachers as participants. They were from seven regions of China, among them 2278 were valid subjects. Constructed on the basis of anxiety content, the Teachers’ State Anxiety Questionnaire (TSAQ) was used in the investigation. The result of the survey shows that primary and middle school teachers are generally affected by state anxiety; further analysis indicates that the prevalence of state anxiety is relatively higher among male teachers, teachers from key middle schools, teachers working more than 10 hours a day, and teachers loaded with additional task as head teachers. This is directly connected with China’s national situation, teaching envi-ronment, discrepancies in teachers themselves, and their own ability of self-regulation.
Evaluation of Microblog Users’ Influence Based on PageRank and Users Behavior Analysis  [PDF]
Lijuan Huang, Yeming Xiong
Advances in Internet of Things (AIT) , 2013, DOI: 10.4236/ait.2013.32005
Abstract: This paper explores the uses’ influences on microblog. At first, according to the social network theory, we present an analysis of information transmitting network structure based on the relationship of following and followed phenomenon of microblog users. Informed by the microblog user behavior analysis, the paper also addresses a model for calculating weights of users’ influence. It proposes a U-R model, using which we can evaluate users’ influence based on PageRank algorithms and analyzes user behaviors. In the U-R model, the effect of user behaviors is explored and PageRank is applied to evaluate the importance and the influence of every user in a microblog network by repeatedly iterating their own U-R value. The users’ influences in a microblog network can be ranked by the U-R value. Finally, the validity of U-R model is proved with a real-life numerical example.

Characteristics of anxiety among primary and middle school teachers: a Content-based approach to state anxiety  [PDF]
Lijuan Wang, Dajun Zhang
Health (Health) , 2012, DOI: 10.4236/health.2012.41006
Abstract: Anxiety has become one of the major psychological problems which harass people in modern times; this problem is particularly obvious with primary and middle school teachers. Based on the contents of anxiety, the self-compiled Teachers’ State Anxiety Questionnaire (TSAQ) was used to investigate the effective of 1930 subjects in seven regions of China through stratified random sampling methodology. The results show that that the sense of anxiety for satisfaction and control is higher in male teachers; and the sense of teachers’ anxiety for satisfaction and conflict is severe in the key middle school; and the sense of conflict anxiety in the married teachers is the highest; the anxiety in all are high in teachers with poor physical health and main teacher as well as the teachers with poor economic situation in their family. The feasibility of measures to improve the teachers’ state anxiety in primary and middle school should be considered to enhance the level of teachers’ mental health, work efficiency and quality of life.

Modeling and Planning on Urban Logistics Park Location Selection Based on the Artificial Neural Network
Lijuan Huang
Journal of Computers , 2012, DOI: 10.4304/jcp.7.3.792-797
Abstract: Nowadays China has been soaked in the craze of planning and construct urban logistics park, and almost all developed countries all regard the urban logistics park’s construction as a major motivation to the national economic. It is vital that the scientific planning of urban logistics park will ensure China’s rapid development. However, too many inappropriate or unscientific planning and construction under the guidance of Government have brought giant economic loss to China. How to plan and design the urban logistics park scientifically, It is a hot topic of research being widely discussed not only by Governments but also enterprisers and scholars home and abroad. This paper begins with exploratory research for modeling and planning on the urban logistics park location selection based on the BP Artificial Neural Network (BP ANN). This paper divides into 3 sections: the first to mainly introduce the history of urban logistics park development and the significance of modelling and planning urban logistics park ,the second to analyze basic principle of the BP ANN, the third to simulate and plan the location selection of urban logistics park based on the BP ANN model. The urban logistics park’s location selection planning is a complicated and dynamical system engineering with a lot of black box problems, which can’t be resloved by System Dynamics, Expert System and traditional mathematical methods (e.g. Operations Research, Statistics), and BP ANN model has seldom been applied to plan urban logistics park in China. So, the research in this paper is an innovation.

Journal of Computers , 2011, DOI: 10.4304/jcp.6.12.2519-2525
Abstract: Algorithms of quadrilateral mesh partition and optimization based on cloud data are proposed in the paper. Quadrilateral meshes are partite by means of dynamic edge-extending according to the types of the nodes. The mesh optimization algorithms are designed, and topology optimization of degree 2 and 3 node and region mesh optimization processing based on viewpoint are programmed and debugged as well. Realizations of the algorithm are introduced in details. The algorithm improves mesh quality and examples are shown to illustrate its feasibility.

Lijuan Zhou
International Journal of Business and Management , 2010, DOI: 10.5539/ijbm.v5n3p223
Abstract: The accounting information is accompanied by the rapid development of information technology; the development is the further deepening of computerized accounting. The large-scale enterprises put more emphasis on development of accounting information, while accounting for the majority of SMES in China because of many problems, there is no implementation of the accounting information or the results are poor, which for economic development of China is a significant impact, thus improving the level of accounting information of SEMS is very necessary. This paper describes in detail the problems faced by accounting information of SEMS and how to resolve these issues to make it a better service for SMES
