Колебания в относительной динамике развития региональных центров России в 2003-2013 годах
The article discusses the effects of concentration of students in the system of higher education in the regions of Russia and methodological approaches to their assessment. The issues of accessibility and inequality in higher education are increasingly being put on the agenda by a number of researchers. Historically, universities are located in large cities, new universities also follow this example, thereby enhancing the effect of concentration. The policy of the Ministry of Education and Science and Federal service for supervision in education and science, aimed at combating low-quality programs and universities, has led to an increase in the concentration of universities in major cities. This fact is confirmed by the calculated Theil and Herfindahl — Hirschman indices and the coefficient of variation. Thus, we can talk about the formation of university oases and deserts. According to our research, more than half of the territory of the Russian Federation constitutes an educational (university) desert
The question of ensuring reliability, especially of durability of mobile communication systems on the stage of planning, is considered in this paper. The purpose of this work is rising quality of projection radio engineering devices (their components) of mobile communication systems. Research of real methods for calculating the indicators of longevity radio engineering devices was conducted for aim achievement. They have some disadvantages, because according to industry standards 4.012.013-84 they use constant value of variation coefficient in mathematical expression. Unified method in the form of IDEF0-diagram was proposed for elimination of defects. It allows to remove quantification of the durability of the constituent parts of the mobile communication systems of «resource» type. Method consists of five successive steps: the formation of source data, updated calculation of variation coefficient, calculation of storage time, evaluation of complex load factor and calculating of indicators of «resource» type. Notably attention is paid to calculating of updated variation coefficient, which makes a significant contribution to the result. It was detected that it is necessary to apply complex load factor in mathematical expressions in the evaluation of resource of radio engineering devices of mobile communicational systems, because it considers both electrical load and temperature, which is explained by the thermally dependent electrical parameters of electrical components. A summary table of the mean group value of the coefficient of variation for certain subgroups of electrical components was compiled. This table is accessory to counting indicators of durability of «resource» type if the necessary electronics are not available in handbooks about reliability. The calculation of the quantitative values of the durability of the video transmitter with the construction of visual dependencies of gamma-percent resource on the complex load factor was completed. Dependences that have been obtained mirror underestimation of gamma-percent resource with the method which is given in industry standards 4.012.013-84 compared with the proposed. It is recommended to integrate the results of research into methodology of calculating of reliability indicators of «resource» type of components at enterprises and research institutes engaged in the development of mobile communication systems.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
One of the most important indicators of company's success is the increase of its value. The article investigates traditional methods of company's value assessment and the evidence that the application of these methods is incorrect in the new stage of economy. So it is necessary to create a new method of valuation based on the new main sources of company's success that is its intellectual capital.
