01.00.00 Physical-mathematical sciences
DescriptionA simple climate–economic model based on the AK model of economic growth with the endogenous depreciation rate linear in temperature and on the exogenous climate scenario with temperature linear in time is considered. The analytical solution of the model is obtained. The uncertainty of temperature projections is introduced in the model, and the moments of model state variable are calculated analytically. Numerical examples are provided

THEORY OF SOCIAL MOTIVATION AS TOOL TO INCREASE SOCIAL PERFORMANCE IN SUB-SAHARAN COMPANIES
DescriptionThis article is about the theory of social motivation as a tool to increase social performance in Sub Saharan countries. So in the first part we will retell the theoretical understanding of motivation and its limits and then the explanation of the concept of social motivation as an alternative to complete the existing and old form of motivation. The second part of the article will talk about social performance and how to measure it. Several techniques are available for measuring performance of an employee. But the difference is in the sources of traits or qualities to be appraised. Jobs are different and have different requirements and different opinion of the management too. The practice is difficult sometime because of different kinds of workers (factory workers, executives or salespeople), which cannot be measured with the same indicators all the time. In this article we will see some theoretical and practical models of performance appraisal based on effectiveness and efficiency at work with concrete indicators. Also the readers will understand how social motivation, when well used in a company can increase the performance and transform the work place into a livelihood place for all stakeholders. And the article will end with the conclusion in which we have a piece of advice and literature references

Description
The Structural Dynamic Economic Model SDEM-2 is essentially a model of a closed economy growing under conditions of conflict of interests of two powerful aggregate actors: entrepreneurs and wage-earners. We study the economic growth within SDEM-2 both in system dynamic and optimization model setups. For the system dynamic model setup, four alternative control strategies of entrepreneurs are considered in detail: the “altruistic” control strategy, the “moderate output growth” control strategy, the “here and now” control strategy, and the “moderate dividend growth” control strategy. In the optimization setup the Pontryagin's maximum principle is applied to SDEM-2 to solve the linear and logarithmic utility maximization problems. The degree of sub-optimality of system dynamic solutions is evaluated

STOCHASTIC DYNAMICS OF PRICES IN A MODEL OF FINANCIAL MARKET WITH DIFFERENT TYPES OF NOISE TRADERS
DescriptionIn the present study, the calculations of price dynamics are made in the model of a financial market consisting of fundamentalist and noise traders. Numerical calculations are carried out in accordance with the full Walrasian dynamic price adjustment rule. To describe fluctuations in the number of optimistic and pessimistic noise traders, a seminal stochastic Kirman’s ant model (reducible to a Markov chain) is used, as well as its modification with different scaling properties of the parameter controlling the strength of herding behavior of noise agents

SINGULAR GROWTH IN AN INTEGRATED ASSESSMENT MODEL BASED ON A MODIFICATION OF THE SOLOW MODEL
DescriptionA modified version of the Solow model with endogenous technical progress is considered that exerts “explosive”, singular growth. A formula for the point of time of singularity is derived. The model is “upgraded” to a climate–economy model (an Integrated Assessment model) describing the growth of the world economy under conditions of global climate change. A non-trivial stationary solution of the model is obtained. It is shown that this solution is unstable, and that the developed model manifests “explosive growth” like the initial modification of the Solow model

PROBLEMS AND PROSPECTS OF THE DEVELOPMENT OF DIGITAL ECONOMY IN SUB-SAHARAN AFRICA
DescriptionThis article deals with the problems and prospects of development of the digital economy of Sub-Saharan Africa. The work will examine the relationship between the development of new information and communication technologies (ICT) and the formation of civil society in the region. The stages of implementation of Internet technologies will be explored. The development in different countries according to national circumstances, understand the basic functions of the new ICT in the development of civil society and freedom of expression and development trends in the region will be studied. Africa itself is not the leader in terms of providing access to a communication area, only 13% (according to research by the World Bank), the inhabitants of the continent using the Internet. But it’s observed in Africa a high growth of the World Wide Web users in a relatively short period. Subsaharan Africa is one of the developing parts of Africa, taking into account the higher interest of the residents, technology is developing faster and the communications is the higher quality, The reason why young people have access to educational, take part in the dialogue with people from different countries, learn about the labor market, are part of a large community of interest, and in consequence are more critical of what is happening around. The article gives a definition of "digital economy" ; the graphs and charts that reflect the level of ICT development and participation of civil society in their distribution ; the participation of civil society in their dissemination ; review: dynamics of development of the digital economy, dynamics of the African telecommunications market, mobile market and all in the region's economy, the incredible pace of development of Internet technologies, socio-economic problems and challenges, the emergence of new jobs, new technology is providing the usual banking services, the emergence of e-government and its impact on the quality of customer service, the appearance of new educational technologies and resources, prospects of technology development and society under the influence of these technologies and more are considered. the data of the World Bank, the UN, Wireless intelligence, PwC, Internet world stats, UIT, GSMA, eMarketer, CNUCED and others. It is a question of purely African technologies like M-Peza, SenGeoSante, Medafrica, Mpedigree, Matibabu and others are used in the article

THE FIRST RUSSIAN TRAVEL RELATION IN SOUTH AFRICA (1808)
10.00.00 Philological sciences
DescriptionThis article examines the story of the unexpected stay of lieutenant Vasily Golovnin in South Africa in 1808 during his famous navigation around the world. In fact, the Russian sailor had to stop in Simonstown for a short while to stock up and put his boat in shape. However, his visit on this archipelago which newly belonged to British had coincided with the moments of crisis between Russian and British empires in Europe. These events obliged Golovnin to stay in the Cape of Good Hope for thirteen months. Enjoying his freedom of movement, the young navigator will exploit this long stay to describe the daily life of South African people. During his travels across the Cape Colony, Golovnin meets with colonists and colonized, and tells about the mechanism of their cohabitation. Even if it is not so abundant, his travelogue remains the first one realized by a Russian on South Africa and will always be crucial for the future generations of Russian mariners who will follow his itinerary. From Kronstadt to Kamchatka, Golovnin described the amazing events, but there, it will exclusively focus on the part of his travelogue [3] about his long and exceptional “stay at the Cape of Good Hope”

Description
The authors made an analysis of biotechnology firms, working in medicine. In terms of the current direction of Russian economy in the process of import substitution, the researched topic of this article has its urgency based on understanding that to build competitive industries in the Russian Federation it is necessary to examine and adjust experience of leading states with certain achievements in pharmacology. Implementation of industry development programmes is possible not only through the active participation by state administration, but also through understanding of how overseas market participants operate. Thus, the object of research is companies of the biotechnology industry, the subject of the research are the financial indicators in relation to industrial value chain strategies. The United States market data was used because of the availability of substantial sources of information that are easier in intelligence conduction, and also due to the fact that the experience of the developed market economy can serve as a model for understanding the work of the business and its patterns for domestic entrepreneurs and public servants. Based on analysis made with descriptive statistics and econometric tools the authors demonstrated the correlation between financial performance and strategy of the value chain

TAX PARTNERSHIP LEVEL ASSESSMENT SCORECARD
DescriptionIn the era of economy globalization it is needed to find the new integration ways. Tax partnership reflects these new realities of integration processes in the territory of former Soviet Union, and it can become one of these new concepts. Tax partnership is offered to consider at the example of Russia and Kazakhstan, as the most initiative members of integration processes. In the article sufficient and necessary information base is offered at the initial stage of tax partnership. Information base requirements for the tax partnership level assessment are extended. The article provides the tax partnership level assessment scorecard, which includes two blocks – quality characteristics, and quantitative indicators. Method of tax partnership level assessment scorecard is developed, which allows estimating the reliable level of tax partnerization. Quality characteristics include similarity level of the taxation systems, certain taxes similarity level and tax partnership productivity. Quantitative indicators include the distance between coordinates and variation indicators regarding tax revenues and tax authorities’ examination. There is a great potential for further development and expansion of the scorecard. By the results of this scorecard it is possible to offer a measure package directed to increase tax revenue in the EEU countries and to improve their tax authorities’ examination
