    In this article the financial reporting is considered and the mathematical model for identification of financially unstable banks of Russia and the world is under construction. Special attention is paid to data collection. They shall be written down correctly and in one dimension for the further analysis. Presently, even more often use mathematical modeling in the analysis of any processes. There is such threshold value or limits of data when which crossing the organization, in our case bank, begins to work at a loss. By means of models the forecast for a future period is done the same. In the bank sphere of Russia since 2013 there were changes and the Bank of Russia toughened control over credit institutions. It became the beginning to mass verification of the reporting of credit institutions and mass revocations of licenses

Purpose of work – definition of the efficiency of flat SC, the choice of the method of its calculation, comparing the result obtained from experimental facts with theoretical, a review of the literature. In the process of the research during the month on the experimental installation were made the measurements of parameters required for definition of the efficiency of flat SC. In the result of the research determined the experimental signification of the efficiency of the SC, as well as theoretical, obtained in result of calculations by the proposed method. Built graphic dependences determining the influence of various factors on the efficiency of SC, performed analysis

    Student-Centered Learning: The Experience of Teaching International Students in Russian Universities

    Get PDF
    The paper focuses on the use of student-centered technologies when teaching international students of the Preparatory Department in the Russian language. The authors review such technologies as problem-based learning, search, research, and design technologies. The main emphasis is on gaming technologies. The feasibility of their use arises from the specific character of education of international students at the Preparatory Department. The paper presents potential applications of these methods and validates their use. The main supporting argument is that student-centered communicative technologies in general, and gaming techniques in particular, improve the quality of training for international students when used in the organization of the learning process. The authors emphasize the need for the teacher's personal activity in the educational process, including the use of student-centered communication technologies
