Research of default risk level of Russian energy
Get PDFThe liberalization of the electricity market intensifies the competition for investors in the Russian energy market, for which the financial stability of energy companies is an important criterion. The paper presents the mathematical modelling of integrated assessment of the default risk level of Russian energy companies, taking into account their specific characteristics: type of the energy business, form of ownership, and regional specific. The research is based on the industry approach to the diagnostics of default risk level of energy companies. The approach includes the logit-model and assessment of the coefficients significance. The complexity of this model is conditioned by the study of external and internal financial and economic indicators, as well as qualitative criteria based on the introduction of dummy-variables. Four groups of default risk level of Russian energy companies are proposed. The use of mathematical modelling tools increases the accuracy of assessing the financial insolvency of energy companies in comparison with the traditional methods. Therefore, the proposed approach is novel, relevant, and practically significant. Research veracity is confirmed by the practical implementation. We recommend the use of the proposed methodology in assessment of the current state and development strategy of Russian energy companies, as well as by investors and analysts to make financial decisions. © 2019 South Ural State University.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Researching the risks of Russian energy companies in the context of renewable energy sources development
Get PDFAs the global market for sustainable energy is growing, a trend towards the development of renewable energy sources (RES) is gaining prominence. Projects related to renewable energy are globally spread and find active government support in many countries. Despite similar trends in the Russian energy sector, its specific nature that is associated with the long-Term development of traditional energy and large-scale power engineering projects creates many barriers to RES development. The article presents an interpretation of the competitiveness of Russian energy companies in terms of renewable energy development. The author presents a classification of risks based patterns that have been identified. Hypotheses about risk distribution along the stages of the life cycle of RES projects based on expert assessment are considered. The results of the study will be used for developing models and practical assessment of the competitiveness of Russian energy companies in terms of RES while taking into account the uneven distribution and varying quality characteristics of risks. © 2017 WIT Press.ACKNOWLEDGEMENT The work was supported with a grant of the Russian Science Foundation (project № 17-78-10039).WIT Transactions on Ecology and the Environmen
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Risk-oriented approach to competition assessment in the global renewable energy sources market
Get PDFThe growing pace of renewable energy development favors a significant change in global energy market conditions. This is due to the crisis of traditional energy, the emergence of new energy sources and arrival of new market players. As a result, forecasting the state of the energy market and assessing the potential of individual regions in terms of the development of renewable energy sources (RES) is becoming quite a difficult task. The article presents a structural analysis of the global energy market in the aspect of studying the dynamics of new capacity and actual production of renewable energy by country and type of energy sources. As a result of the analysis, the author has grouped countries participating in the market on the basis of indicator values reached: front-runners, average performers and stragglers. The author presents an approach for assessing competition in the global renewable energy market – a “thermometer” of competition. Its features include assessment of aggregate specific risk that is unique for each energy market country-member. The final assessment of the “temperature” in the global energy market is based on taking into account the total aggregate risk in one of the three zones of the “thermometer” scale. The results of the study will be used for improving the presented approach, developing an integrated methodology for the ranking of regions in the energy market, and the practice-based assessment of competition in the global market of renewable energy, taking into account the potential of individual participants. © 2018 WIT Press.2 GLOBAL RENEWABLE ENERGY MARKET The study of the global renewable energy market is based on the assessment of maximum capacity and actual production in the energy market, including the regional aspect. Market research was conducted using statistical data published by the International Renewable Energy Agency [1], [2], Renewable Energy Policy Network for the 21st. Century [3], [4] and other sources [7], [8].6 ACKNOWLEDGMENT The work was supported with a grant of the Russian Science Foundation (project № 17-78-10039)
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
