Increasing territorial capitalization by incorporation of small enterprises into clusters

Modernization of the Russian national economy depends on small businesses and their involvement in capitalization of the territorial potential. This article discusses methods, models, and mechanisms of territorial capitalization based on incorporation of small business enterprises into clusters along with medium- and large businesses. We propose an optimization model for assessing the efficiency of such clusters: our research has shown that this model can be applied for decision-making in regional strategic planning. Methodologically, this study relies on the theories of industrial development and economic growth, the industrial cluster theory, and the works of Russian and international researchers on mechanisms of management of territorial potential, their establishment and implementation. Capitalization of the region's resource potential manifests itself in the form of static and dynamic effects. We developed models of interaction between small and other businesses and structures within a cluster oriented towards territorial capitalization. We demonstrated that incorporation of a university into a cluster structure increases the innovative capacity of all cluster members. This research may be further expanded to study the mechanisms of involving small businesses operating in peripheral areas into clusters

Use of Engines Manufactured by SE "Zorya"-"Mashproekt" GTR&PC for Renovation of the Gas Transportation System of "Ukrtransgaz" PJSC

The article observes potential participation of SE "Zorya"―"Mashproekt" GTR&PC in implementation of the program for renovation of Ukraine’s gas transportation system facilities. The mentioned state enterprise, as an originator of the method of compressor stations renovation by means of a heavy upgrading of gas pumping units, has a long experience of successful implementation of tens of such projects in the Russian Federation, Ukraine, Bulgaria. The examples and propositions for modernization of gas pipe-lines of "Ukrtransgaz" PJSC gas transportation sys-tem are set forth in the article

Pinned Low Energy Electronic Excitation in Metal Exchanged Vanadium Oxide Nanoscrolls

We measured the optical properties of mixed valent vanadium oxide nanoscrolls and their metal exchanged derivatives in order to investigate the charge dynamics in these compounds. In contrast to the prediction of a metallic state for the metal exchanged derivatives within a rigid band model, we find that the injected charges in Mn$^{2+}$ exchanged vanadium oxide nanoscrolls are pinned. A low-energy electronic excitation associated with the pinned carriers appears in the far infrared and persists at low temperature, suggesting that the nanoscrolls are weak metals in their bulk form, dominated by inhomogeneous charge disproportionation and Madelung energy effects.Comment: 4 figure

Fostering parent–child dialog through automated discussion suggestions

The development of early literacy skills has been critically linked to a child’s later academic success. In particular, repeated studies have shown that reading aloud to children and providing opportunities for them to discuss the stories that they hear is of utmost importance to later academic success. CloudPrimer is a tablet-based interactive reading primer that aims to foster early literacy skills by supporting parents in shared reading with their children through user-targeted discussion topic suggestions. The tablet application records discussions between parents and children as they read a story and, in combination with a common sense knowledge base, leverages this information to produce suggestions. Because of the unique challenges presented by our application, the suggestion generation method relies on a novel topic modeling method that is based on semantic graph topology. We conducted a user study in which we compared how delivering suggestions generated by our approach compares to expert-crafted suggestions. Our results show that our system can successfully improve engagement and parent–child reading practices in the absence of a literacy expert’s tutoring.National Science Foundation (U.S.) (Award Number 1117584

Annotated bibliography of the Russian literature on glaciology for 2014

The proposed annual bibliography continues annotated lists of the Russian-language literature on glaciology that were regularly published in the past. It includes 271 references grouped into the following ten sections: 1) general issues of glaciology; 2) physics and chemistry of ice; 3) atmospheric ice; 4) snow cover; 5) avalanches and glacial mudflows; 6) sea ice; 7) river and lake ice; 8) icings and ground ice; 9) the glaciers and ice caps; 10) palaeoglaciology. In addition to the works of the current year, some works of earlier years are added, that, for various reasons, were not included in previous bibliographies

Fair Value Accounting Model for Stock Indices

When forming the risk portion of an investment portfolio, one may include into it both stocks of individual companies representing different sectors of the economy in different regions, and derivative financial instruments, such as futures on stock indices. The latter are an excellent instrument for investing in a country's stock, eliminating the necessity for the investor to solve the non-trivial problem of determining the optimal set of attractive assets, because, as a rule, the stock index includes the most successful companies in most industries. If one only decides to include stock indices in the portfolio on the basis of their current price, it can be assumed that in the moment one should invest in assets that have not gone up at all or enough, yet. However, this estimate is not objective, as indices have different volatility, and therefore, it is incorrect to compare the absolute size of the drawdown in crisis time, and those of the growth rate in the post-crisis period, if one wants to determine overvalued and undervalued assets. Obviously, when making the final decision on whether to include stock indices in the portfolio, it is also necessary to rely on the results of a fundamental analysis of these assets. So, the articles aims at determining the structure of the risk portion of the investment portfolio by identifying instruments that are underestimated in terms of their fundamental characteristics. To achieve the aim of the study, the following main tasks were solved: the initial set of exogenous factors influencing the dynamics of stock indices was determined; the parameters of the models of stock indices dependence on the factors influencing them are assessed, the corresponding projected values are calculated; a set of instruments is determined for including stock indices in the investment portfolio by comparing their real and model values. The models created make it possible to determine the optimal structure of an investment portfolio, which would include stock indices futures for such countries as Taiwan, Mexico, Brazil, Great Britain, Germany and the USA

Determining an Optimal Structure of a Portfolio Containing Assets of Mature and Emerging Markets

In the modern world, derivatives on leading stock indices are very often the focus of attention of portfolio investors. Inclusion of such tools in a portfolio actually allows investing immediately in the economy of a particular country or its individual sector. The aim of the work is the formation of an optimal investment portfolio containing derivatives on stock indices of countries with mature and emerging stock markets. To achieve this goal, the study solves the following tasks: two optimal portfolios — the portfolio containing indices of developed countries and the portfolio containing indices of emerging countries — are formed; the mixed portfolio containing indices of both sectors is formed; a comparative analysis of the effectiveness of the resulting portfolios is carried out. To obtain an optimal portfolio structure, the Markowitz model is used. The results of applying this model allow to draw the following conclusions regarding the investment attractiveness of the stock market of mature and emerging economies. In terms of portfolio risk level, it is possible to obtain a couple of portfolios, one of which would contain only assets of mature markets, and the other — only assets of emerging ones. However, in this case, the level of profitability will be significantly lower in the portfolio consisting of assets of the mature sector. The mixed portfolio provides a much wider range of alternative investment options based on the efficient frontier, both in terms of the risk and profitability criterion
