The use of new technologies, designs of agricultural machines, as well as the correction of the situation that developed in 1990-2015, led to the need for an accelerated renewal of the machine-tractor fleet in the agricultural production of Russia. One of the instruments of this process is state support. Therefore, it is required to develop the state regulation new methods that stimulate the purchase of new equipment by agricultural producers. Our study purpose is to determine the possibilities of using the commodity lending mechanism to upgrade the machine-tractor fleet in modern conditions. The following tasks are supposed to be solved: - consideration of the using commodity lending experience as a state agrarian policy element; - formulating a mechanism for commodity lending, taking into account the lending object (equipment) characteristics; - determination of this mechanism parameters. One of the effective tools is commodity lending, adapted to the lending object characteristics. It is rational to use the repayment of the principal amount, both in cash and in products. Why use a grain equivalent, the basis of which will be the price of the 4th class wheat grain. In 2022, the purchase of an average tractor requires 324 tons of grain, and the purchase of a grain combine requires 657 tons (or 64.7 tons and 131.4 tons per year, respectively).

To increase the stability of the banking system, it is necessary to use effective systems of risk management and monitoring of banks. One of these systems is the internal procedure for capital adequacy assessment (IPCAA). The purpose of this study is to assess, using a statistical analysis, the impact of the IPCAA procedure on changes in the value of banks' capital adequacy ratios. Some results of monitoring data are presented on risk-weighted assets, level 1 and 2 capitals, and capital adequacy ratios (CAR) for two foreign (2008 - 2018) and three Russian banks (2014 - 2018) . The study showed the direct effect of increasing the risk-weighted assets on the level of capital adequacy (CAR). The results obtained allow concluding that there is a direct significant connection between the IPCAA procedure use and the stability of banks. This procedure provides a comprehensive assessment of the overall capital adequacy of banks, taking into account the existing risks in order to maintain an adequate and stable forecast level of capital. The study also revealed the needs of banks in creating adequate structures to ensure proper management of financial and operational risks, which will simplify the IPCAA process and ensure more effective capital planning and decision-making to provide the stability of both individual banks and the entire banking system.

The main factor of making a decision or solving a problem is having enough information; the more parameters are given, the easier the solution. The problem considered here is to determine whether to give a credit to an applicant or not. A lot of information about the applicant is needed in order to make this decision. This information can be obtained from the applicant himself or from the agencies specialized in such business. Now, the largest and renewable source of information about people is the social networks. They are an inexhaustible resource, and that is so valuable for advertising companies, banks and lenders, who usually suffer from a lack of data about applicants for a loan and cannot determine the credit scores accurately. In this paper, the authors present a few models that can extract social networks data and use them to predict the statues of an applicant based on the data on similar applicants. The data of social network VKontakte (http://www.vk.com/) are used. [ABSTRACT FROM AUTHOR]

Mining and processing of minerals is one of environmentally hazardous activities. Mining companies, as a rule, are characterized by a significant impact on the environment. In this regard, an environmental monitoring is an important element of mining production in Russia as well as in many other countries. Due to development in Russia the system of environmental legislation and with the increase in the size of environmental taxes and fines there is increasing the role of monitoring in ensuring of economic security of mining enterprises. This article analyzes the basic legislative acts of Russia in the sphere of nature use and environmental safety. The requirements on conducting the monitoring of atmosphere, hydrosphere, soil and vegetation in the influence zone of mining companies' objects are determined and systematized. Also, there are considered the regulations governing the calculation of the fines for harm for water bodies and soils, when this harm occurred as a result of environmental laws violations. The basic methodological approaches of such calculations are described and the estimates of possible fines size are given. It is concluded, that the presence of effective environmental monitoring system may contribute much not only in providing environmental safety of mining production, but also in minimizing the risk of financial loss due to deprivation of the company license for subsoil use or the presentation of fines for environmental violations.

The aim of the study is to investigate the possibility of applying the concept of "steady state with minimal entropy production" for environmental and socio-economic systems. The method of research is - the theoretical description by means of tools of thermodynamics of irreversible processes (TIP) the transport phenomena in a continuous ecological system consisting of two subsystems. Each subsystem is a population of animal individuals which perform complex movement supposed as chaotic. The average energy of random motion of the individuals in one subsystem is different from the average energy of the chaotic motion in other subsystem. The subsystems are combined in the system by means of the channel through which the individuals can move from one subsystem to another. In each subsystem of the ecological system the state is described by the logistic equation. In the case of removing the requirement for the existence of a finite derivative of the logistic equation and transition to a finite-difference one dimensional logistic map, there is discussed the case of occurrence of bifurcation points. It is shown that in case of occurrence a steady state, in the discontinuous system a possibility arises to control one of the parameters of the logistic equation in one of the subsystems from the other subsystem. In the case of transition to the finite-difference logistic map, above mentioned phenomenon can lead to the occurrence of bifurcation points in one of the subsystems when changing parameters in another subsystem.

Social media over the few of its existence has been a technological innovation, which has made information communications easily accessible to the all groups of people from all walks of life. But, just as every great tool has its drawbacks, social media also has its own drawbacks and risks connected with it. Social media has led to the increase in cases of cyberbullying whereby a group of people or individuals are intimidated or threatened with messages from other people. Every user of social media is vulnerable to abuse on social media. The main objective of this research is to study abuse on social media and to develop a real-time system that will able to automatically detect these threats and abuses. This document focuses on the Twitter social networking service as a case study. The study used a qualitative methodology to acquire an understanding of social media, the risks associated with and how to detect abuse. A model for a real-time analytical system which would receive a stream of Twitter data and analyze the level of abuse was documented. The methodology involved a proposition of the use of cloud computing technology with the aim of keeping the real-time processes running uninterrupted. The Microsoft Azure platform is suitable. By interfacing the RStudio IDE (Integrated Development Environment) with the Twitter API (Application Programming Interface), the R language was used to analyze the twitter stream data stored in a dataset and generated various real time reports of abusive words based on our set preferences and data mining techniques.

This paper addresses the example of information technologies application in management of greenhouse gases and wastes. There was developed an information system for conducting a greenhouse gas inventory at a regional level. It is designed in accordance with the recommendations of "Guidelines for National Greenhouse Gas Inventories" (IPCC 2006). The system provides collection, storage, processing and analysis of the information, as well as preparation of the required forms and reports on greenhouse gases emissions and removals. The ability of the system use in the field of waste management is ensured by the presence of the module "Waste" in its structure. This module consists of the following four blocks: "Solid waste", "Incineration and open burning", "Treatment of the municipal waste water", "Biological treatment of solid waste". The information about some types of waste is presented in other modules. In particular, the module "Agriculture" takes into account the greenhouse gases emissions resulting from the cultivation of domestic animals, as well as from systems of harvesting, storage and using of manure and litter. Such information can be also useful for estimation of bio resources which could be used in producing of biogas and energy. System is implemented as a program (executable file), a database file and auxiliary files. It includes five subsystems: "Database processing", "Report generation", "Data export and import", "System kernel" and "Analytical block". The system was successfully tested in the Khanty-Mansiysk Autonomous District of Russia and now is used as decision support tool by the District's Administration. [ABSTRACT FROM AUTHOR]

Land-use regression (LUR) models are successfully used in Europe and United States of America in recent 10-15 years for atmospheric air pollution description. The models provide getting the air pollution maps on a large area with high spatial resolution (~ 10 m) and relatively small financial and time costs. The paper is devoted to assessment of the land-use regression (LUR) method applicability for description of snow cover's pollution. Snow may be used as a good indicator of air pollution in many Russian regions where snow lies about 4-6 months a year and accumulates all substances coming from atmosphere. The assessment was done for Karabash city, which is one of the most polluted Russian cities due to long activity of «Karabashmed» copper smelting plant. The study showed that the LUR method can be successfully applied for description the dust deposition density from atmosphere and further use as a part of environmental monitoring systems.

In the paper we consider economically motivated problems, which are treated with the help of methods of portfolio theory that goes back to the papers by H. Markowitz [1] and J. Tobin [2]. We show that the portfolio theory initially developed for risky securities (stocks) could be applied to other objects. In the present paper we consider several situations where such an application is reasonable and seems to be fruitful. Namely, we consider the problems of constructing the efficient portfolio of banking services and the portfolio of counteragents of a firm. [ABSTRACT FROM AUTHOR]
