CONSEQUENCES OF DECISIONS FOR SCIENCE-TECHNOLOGY AND ECONOMIC DEVELOPMENT

abstract 1131509029 issue 113 pp. 355 – 387 30.11.2015 ru 574
The real facts presented in this article, demonstrate the great importance in today's world of strategic management, methods of analyses of innovations and investments and the role of the theory of decision-making in these economic disciplines. We have given the retrospective analysis of the development of nuclear physics research. For the development of fundamental and applied science in the second half of the twentieth century, we had a very great importance of the two events: the decision of US President Roosevelt to deploy nuclear program (adopted in response to a letter from Einstein) and the coincidence in time between the completion of the construction of nuclear bomb and the end of World War II. The nuclear bombing of Hiroshima and Nagasaki has determined the developments in science and technology for the entire second half of the twentieth century. For the first time in the entire history of the world the leaders of the leading countries clearly seen that fundamental research can bring great practical benefit (from the point of view of the leaders of countries). Namely, they can give the brand new super-powerful weapon. The consequence was a broad organizational and financial support of fundamental and deriving from them applied research. Is analyzed the influence of fundamental and applied research on the development and effective use of new technology and technical progress. We consider the development of mathematical methods of research and information technology, in particular, the myth of "artificial intelligence"

CONTROLLING OF CONSUMER PRICES DYNAMICS AND LIVING WAGE

abstract 1261702030 issue 126 pp. 403 – 421 28.02.2017 ru 98
In accordance with the Presidential Decree of 21 August 2012 № 1199 one of the 11 integrated indicators of the activity of executive authorities is the measure "real disposable income of the population". For its calculation it is necessary to measure the level of consumer prices. The article presents the minimum consumer basket of physiologically essential food products, designed in 1993 by the Institute of High Statistical Technologies and Econometrics (IHSTE) based on the initial data of the Institute of Nutrition of the Russian Academy of Medical Sciences, and the results of measuring the cost of the consumer basket IHSTE and inflation index in 24 years (1993 - 2017). We discuss the application of the developed tools in Controlling of the level of consumer prices and living wage. According to M. Orshansky, living wage can be estimated by multiplying the cost of the minimum food basket by a factor which is equal to the quotient of all costs to the costs of food costs for a poor family. This work is aimed at the elimination of the monopoly of Rosstat in the calculation of indices of inflation, the living wage and the real disposable income of the population. The methods of the measurement and the use of inflation constitute an important part of training courses in econometrics, which are taught in the context of the scientific-educational complex "Engineering Business and Management" of the Baumann Moscow State Technical University. Nobel Laureate in Economics Vasiliy Leontiev thought that only 1% of economists analyze the newly collected data, 30% use the data contained in the publications of predecessors, and the rest did not turn in their arguments to the real world. This work belongs to the 1% of publications (which analyzes the newly collected data), about which Vasiliy Leontiev wrote

CURRENT STATUS OF NONPARAMETRIC STATISTICS

abstract 1061502017 issue 106 pp. 239 – 269 28.02.2015 ru 740
Nonparametric statistics is one of the five points of growth of applied mathematical statistics. Despite the large number of publications on specific issues of nonparametric statistics, the internal structure of this research direction has remained undeveloped. The purpose of this article is to consider its division into regions based on the existing practice of scientific activity determination of nonparametric statistics and classify investigations on nonparametric statistical methods. Nonparametric statistics allows to make statistical inference, in particular, to estimate the characteristics of the distribution and testing statistical hypotheses without, as a rule, weakly proven assumptions about the distribution function of samples included in a particular parametric family. For example, the widespread belief that the statistical data are often have the normal distribution. Meanwhile, analysis of results of observations, in particular, measurement errors, always leads to the same conclusion - in most cases the actual distribution significantly different from normal. Uncritical use of the hypothesis of normality often leads to significant errors, in areas such as rejection of outlying observation results (emissions), the statistical quality control, and in other cases. Therefore, it is advisable to use nonparametric methods, in which the distribution functions of the results of observations are imposed only weak requirements. It is usually assumed only their continuity. On the basis of generalization of numerous studies it can be stated that to date, using nonparametric methods can solve almost the same number of tasks that previously used parametric methods. Certain statements in the literature are incorrect that nonparametric methods have less power, or require larger sample sizes than parametric methods. Note that in the nonparametric statistics, as in mathematical statistics in general, there remain a number of unresolved problems

DEVELOPMENT OF SOLIDARY INFORMATION ECONOMY

abstract 1211607007 issue 121 pp. 262 – 291 30.09.2016 ru 281
We are developing a new organizational-economic theory - solidary information economy, based on the views of Aristotle. The name of this theory has changed over time. Initially, we used the term "nonformal information economy of the future", and then began to use the term "solidary information economy." In connection with Biocosmology and neo-Aristotelism preferred is an adequate term "functionalist organic information economy". This article summarizes the first phase of work on the solidary information economy. We have analyzed the array of publications. The main problems are discussed, the solution of which is devoted to research related to the considered basic organizational and economic theory. The founder of the economic theory is Aristotle. We discuss Aristotle's positions, on which the economic theory is based, in particular, solidary information economy. We prove that the market economy has remained in the XIX century and the mainstream in modern economic science - justification of insolvency of a market economy and the need to move to a planned system of economic management. We examine the impact of ICT on economic activity. We develop the approaches to decision-making in the solidary information economy. On the basis of modern decision theory (especially expert procedures) and informationcommunication technologies people can get rid of chrematistics and will understand the term of "economy" according to Aristotle

DISTRIBUTIONS OF REAL STATISTICAL DATA ARE NOT NORMAL

abstract 1171603003 issue 117 pp. 73 – 92 31.03.2016 ru 256
In the training courses on the theory of probability and mathematical statistics there are various parametric families of distributions of numerical random variables considered. Namely, we have been studying the families of normal distributions, log-normal distributions, exponential distributions, gamma distributions, Weibull-Gnedenko distributions, etc. All of them depend on one, two or three parameters. Therefore, for a complete description of the distribution it is sufficient to know or estimate one, two or three numbers. Parametric theory of mathematical statistics is widely developed, where it is assumed that the distribution of observations belong to one or another parametric family of distributions. This tradition comes from Karl Pearson, who in the early twentieth century proposed the use of four parametric family of distributions. The above families of distributions - are the subsets of a four-parametric family of Pearson. Unfortunately, parametric families exist only in the minds of the authors of textbooks on probability theory and mathematical statistics. In real life, they are not. Therefore, modern applied statistics and econometrics mainly use non-parametric methods, in which the distribution of observations can have arbitrary form. First, on an example of a normal distribution, we are discussing the impossibility of practical use of parametric families of distributions to describe specific statistical data. We give the results of research of metrologists and estimation of convergence in limit theorems. Then we discuss how the parametric methods can use for reject outlying observations. It is very unstable the significance levels for a fixed rejection rule and the parameter of the rejection rules for a fixed level of significance. Consequently, the rejection of the classic rules of mathematical statistics is not sciencebased

DO WE ALWAYS NEED A SUPPLIER’S QUALITY CONTROL?

abstract 0961402070 issue 96 pp. 974 – 987 28.02.2014 ru 1141
The higher the level of quality achieved, the greater the control size - this is the paradox of the classical theory of statistical control. A possible way out is to move to the technical policy based on economic characteristics. Shifting control to the consumer may be economically profitable. We have considered two variants of technical policy - increasing lot size and replacing defective product units at the consumer

ECOLOGICAL SAFETY: UNDERGROUND NON-ENVELOPED TANKS IN PERMAFROST FOR WASTE DISPOSAL DRILLING

abstract 1171603002 issue 117 pp. 52 – 72 31.03.2016 ru 133
The actuality of ecological issues was realized about 50 years ago. The highlight of the ecological movement to protect the environment has been, in our estimation, the United Nations Conference on Environment and Development (Rio de Janeiro, 1992), which adopted the concept of sustainable development. After 1992 the interest in ecology of broad masses was decreased slightly, although the environmental problems are not only remained, but appeared to a greater extent. However, now there is a legal basis for their decisions. Particularly, enterprises must have a certified environmental management system; otherwise they will be unable to compete in international markets. Awareness by humanity of need for environmental protection has led, in particular, to the deployment of scientific research in the field of ecological safety studies. Therefore, we have found that it is necessary and useful to report about the research of our team on this subject. Ecological security issues are highly relevant to the energy sector, in particular for gas enterprises. As an example of the new scientific results we discuss the innovative approach to the disposal of drilling waste. The basic idea - the use of underground non-enveloped tanks in permafrost soil for disposal of drilling waste. Permafrost is typically a negative impact on economic development, but in this situation it is the determining factor for a positive role, enabling lower costs to ensure ecological safety and, consequently, improve the competitiveness of domestic enterprises in the global gas market. This article is devoted to methods of dumping drilling waste and the problems that arise in their burial place. We discuss various methods of waste disposal, their advantages and disadvantages, as well as the impact on the environment
