Based on the study of an indicator index system that depicts the epidemic situation of Severe Acute Respiratory Syndrome (SARS), this paper proposes an approach to divide the epidemic process of SARS into four typical stages. According to these indicator indexes in different stages, the key influence elements over the epidemic from the outbreak stage to convergent stage are investigated; also the convergent conditions of the number of daily additional patients and the number of patients in hospital are discussed. Further more the predictive modeling on the termination of epidemic is presented. As the case study, the data analysis of SARS in Beijing and Hong Kong demonstrate the reasonability and validness of the approach. And the data when Beijing can release from the SARS travel recommendation of WHO is finally predicted.
Theory of development is focal proposition of Marxism. From view of philosophy, esp. with standpoint and method of Marxism, this paper ponder over development and innovation as well as their essence and regularity. Innovation and development involves the concept of dialectical unity, both are scientific summary to essential law of nature and human society by Marxism, both are effective approach and measure for human being to understand and change the world. Innovation is the source, motivation and practical demand of development, development is direction, target and destination of innovation. Marxist theory of development is theoretical foundation of innovation, meanwhile, innovation is key embodiment for Marxist theory of development.

The essence of the reorganization is generally regarded as the institution of judicial prevention of bankruptcy, which sets the legal goal to rebuild and clear its credit and debt by the way of judicial procedure. At present, as a part of the bankruptcy law in China, reorganization of bankruptcy is widely criticized as the model of the legislation failure. One of the essential causes is that the fundamental theory and operating mechanism was not necessarily coordinated at that moment. While amending the bankruptcy law, the author re-evaluates its function, value and internal structure, and puts forward the establishment of the strategic method to the efficient reorganization institution in China.

Because there is no profit incentive, the organizations for gratuitous services are generally considered having serious incentive difficulty, but most of which have the same efficiency as for-profit-enterprises. This implied that, except profits, many other incentive mechanisms are also important. "Output benchmark" and "self-incentive" are main incentives in the organizations for gratuitous services. The paper analyzes these two incentive mechanisms using principal-agent model and indicates that "the long term benefit" and "altruism" can produce strong incentive to the agents, but the existence of the uncertainty weakens their incentive effects.
Based on the transaction cost analysis of the enterprise vertical efficient boundary, the authors think that the thrift of transaction cost and the profit increase caused by the transaction structure are the driving force of enterprise vertical efficient boundary variance. Follow the method of O.E. Williamson, the authors use technical efficiency and agent efficiency to analyze the efficient boundary and discuss the hyper-competitive environment effecting on the efficient boundary. The conclusion is that the border will vary in certain ranges, so the transaction in the range can be governed by the inter-firm cooperation. And then, the authors propose a model of an enterprise vertical efficient border in the hyper-competitive environment.
Compositional data are widely used in the field of society, economy and technology. This paper discusses two different forecast modeling methods of compositional data .The first method supplies a forecast model making use of logarithm change. Sphere projection, a non-linear approach for dimensionality deduction, is used in the second method to build a forecast model. With the contrastive study, the paper lists out the advantage and disadvantage of each. The methods talked above are respectively used in the compositional data of the Beijing employees from 1994 to 2000 that are divided by proprietorship. In the end of this paper, the status of employment in Beijing is analyzed.
Open-end funds are today's main form of global mutual funds. Based on the risk characteristics faced by open-end funds, this paper studied the no-load and load funds' optimal holding scale of risky assets, and developed the relevant models.
The paper examines the impact of technical trend signals on Shanghai stock market using an adaptive expectation model based on consistent investment behaviors. The result shows that Shanghai stock market is sensitive to the technical signals. And as far as the trading charges are concerned, only the minority investors, with technical analysis, may possibly gain abnormal returns, while the majority operating according to technical trend signals would assume significant risks.
Artistic form is of justice function for its legal existence. Its interference of the history narrative makes it a background and makes art narrative a foreground, which breaks history narrative and leads to the autonomy of art. And it is a perceptual defense of human aesthetic impulse. Also, the political significance of its poetic system constructs some subtext with its fictional justice function.
