To explore new ideas for treating sludge in the urban rivers, 4 different sludge treatment schemes were proposed, the construction safety, projection duration, enthusiasm of the public, environmental coordination, resource utilization, supporting of government, benefits, and project cost of the schemes were selected as the main evaluation indexes, and the projection pursuit model was introduced to evaluate the schemes comprehensively. Results showed that: the evaluation and selection of sludge treatment schemes conformed to the calculation requirements of the projection pursuit model; S3 was the optimal sludge treatment scheme with best comprehensive benefits, the projection value of which was recorded as 1.198, much more than that of other treatments. Therefore, it was concluded that using sludge to produce brick (S3) was more appropriate for the sludge treatment in urban rivers, and which depended on the wide market of bricks and had good practical benefits. The study achievements could provide beneficial basis for the river management and the sludge treatment in cities, and also provide the practical basis for the application of statistical models on the selection of project schemes.

Scientific evaluation of the competitiveness of China’s dairy industry is of great significance to the development of regional dairy industry. In view of the fact that the existing evaluation model cannot solve the dynamic nonlinear optimization problem, this paper established a projection pursuit model based on accelerating genetic algorithm and carried on the comprehensive evaluation and dynamic analysis on the competitiveness of dairy industry in China’s 31 provinces and cities (not including Hong Kong, Macao, and Taiwan) from five dimensions, namely, basic factors of production, the industry demand conditions, the enterprise competitiveness and growth force, related and supporting industries, and the natural environmental elements. It was found that firstly, from the perspective of time, the development trend of China’s dairy industry basically shows a positive trend. With the improvement of national living standards, the competitiveness of the dairy industry is also constantly improved. Secondly, from the perspective of space, regional differences in the competitiveness of the dairy industry are significant. Inner Mongolia, Heilongjiang, Shandong, and Hebei are at the forefront of the development of the industry, while the development of the dairy industry in the rest of the region has a big gap with those areas. From the perspective of regional layout, the advantageous region of China’s dairy industry has been preliminarily formed, and the competitive advantage is mainly concentrated in the northern region. Accordingly, the countermeasures and suggestions to enhance the competitiveness of China’s dairy industry were put forward.

To overcome the deviation caused by the effect of subjective factors in drill wear evaluation, and make the evaluation more accurate and objective, on the basis of drill wear comprehensive evaluation criterion, the projection data are built with projection pursuit method. Two hundred drill wear comprehensive evaluation samples are randomly generated within the range of each class. The projection pursuit model is built by unitary processing according to these samples, which converts the evaluation into non-linear multi-constrained optimization problems. The optimal projection direction vector and the weight coefficient of each evaluation index are obtained with composite simplex method. Meanwhile the corresponding relationship between the region of variation of projection eigenvalue and classification grade is established. The precision of sample evaluation reaches 100% and the evaluation of the measured data achieves good effect. Thus, the scientific evaluation of drill wear is realized by the projection pursuit model.

ABSTRACT Religious traditions in Indonesia are known to be very moderate and tolerant abroad is a reflection of the character of a great noble nation. Between religion, tradition and culture are able to perform compounds so as to create a genuine religious harmony. Because of this reality Indonesia is regarded as the largest Muslim majority country in the world that almost without conflict, in the midst of reality Muslim countries in the Middle East that impressed the dispute into the daily menu. However, the reality of Indonesia as a moderate nation is injured by the act of a group that is fond of terrorism and radicalism by riding Islamic religious teachings. Thus, this reversed religion is assumed as a source of cruelty.   It is through that phenomenon researcher, feel the need to examine the strategy of disseminating moderate Islam by Nahdlatul Ulama. The selection of this Islamic organization according to the authors due to its success in moderating Islam in Indonesia. In this study, the study using a qualitative approach or method as well as adopting the theory of Van Dijk discourse analysis as a scalpel to peel the discourse of moderate Islam published by PWNU East Java through the website. As for this research, the findings are important, among others are: 1) moderate Islamic discourse campaigned by Nahdlatul Ulama East Java is categorized into three segments, namely social, religious and nationality. 2) the text structure that builds moderate Islamic discourse NU East Java in Van Dijk perspective constructed in three domains, namely text, social cognition and social context. 3) the principles of Public Relationship implemented by NU through cyber (online media), among others; News publications and expert opinions, production of image and video-based information, and updating official NU information to the public about their attitudes and views on the phenomena that occur by promoting the values of Islamic moderatism. Key Word : Islamic Moderatism, Nahdlatul Ulama, Cyber Public Relationship

The article is devoted to the modern Russian party system. In the first part of the article, the author shows the historical features of the parties formation in Russia and analyzes the reasons for the low turnout in the elections to the State Duma in 2016. According to the author the institutional reasons consist in the fact that the majority of modern political parties show less and less ability to produce new ideas, and the search for meanings is conducted on the basis of the existing, previously proposed sets of options. Parties reduce the topic of self-identification in party rhetoric, narrowing it down to “branded” ideas or focusing on the image of the leader. In addition, the author shows the decrease in the overall political activity of citizens after the 2011 elections, and points out that the legislation amendments led to the reduction of the election campaigns duration and changes in the voting system itself. The second part of the article is devoted to the study of the psychological aspects of the party system. The author presents the results of the investigation of images of the parties as well as the results of the population opinion polls, held by the centers of public opinion study. On the basis of this data, the author concludes that according to the public opinion the modern party system is ineffective, and the parties don’t have real political weight, which leads to the decrease of the interest in their activities and confidence in them. The author supposes that all this may be the consequence of the people’s fatigue from the same persons in politics, but at the same time the electorate’s desire to see new participants in political processes is formulated rather vaguely, since, according to the people, this might not bring any positive changes.
