Geek Culture As a New ‘Image’ of Contemporary Culture

The aim of this article is to present the theoretical grounding of geek culture as a unique contemporary phenomenon, based on structural-functional, evolutionary, and systemic methodology within the overarching culturological approach. We verify the meaning of such concepts as ‘geek’, ‘geek community’, and ‘geek culture’; explore the role and the characteristics of geek culture as a supra-subculture; analyze its global universal features and the specifics of its Russian variant; describe a unique characteristic of geek culture as a self-organizing system; and highlight the dualistic features of geek culture as a ‘marker’ of contemporary social processes.     Keywords: geek, geek culture, geek community, supra-subculture, consumer subculture, mass subculture, youth subculture, counter-culture, mainstrea

Situational analysis of socio-cultural interaction of states under conditions of globalization

The present article considers the possibilities of the paradigm of socio-cultural interaction when analyzing international relations. Traditional activity approaches in explaining this interaction are critically assessed, and the main situations of interstate interactions that have a socio-cultural importance are analyzed. The offered problematisation when studying global strategies of interstate relations in terms of socio-cultural interaction makes it possible to consider desirable strategies and scenarios for improving intercultural communication and international cooperation. Possible prospects on changing the basic benchmarks of the globalization processes based on socio-cultural interaction for its further humanization are outlined. The revealed mechanisms of the dynamics of socio-cultural interactions when moving from one situation of interaction to another, as well as the role of the cultural reality formed for this purpose and overcoming the one-sidedness of economism in international relations can provoke the researchers’ interest. The offered analysis of the situations of socio-cultural interaction enables the authors of the article to clarify some positive opportunities of the globalization in the overall civilization development and intercultural dialogue of all countries of the world community. The results given in the article in relation to studying the main reasons of the discrimination in interstate relations and offers on overcoming it by using the spiritual and moral potential of the world culture are also of great importance.peer-reviewe

Методика рейтингования компаний IT -сектора по уровню рисков кредитоспособности

The subject of the research are the companies of the IT sector, as a strategically important sector in the information age. Their development of companies in the IT sector is associated with high risks and requires large volumes of investments, including attracting bank loans. In this regard, the purpose of the study was to develop an adequate sectoral methodology for rating companies in the IT sector by the level of creditworthiness risks using mathematical and statistical tools that make it possible to reliably assess the potential risks of investors. To achieve this goal, the study proposes a methodology for assessing the creditworthiness of IT companies based on a system of risk factors, which makes it possible to quantify the exposure of companies to two generalized risk groups: financial risk and business risks. Based on the cluster analysis, a rating table has been developed, according to which, depending on the calculated score, the category of the company’s creditworthiness is determined. The study concluded that the key factors affecting the creditworthiness of companies are: indicators of financial stability, return on assets, liquidity ratio, online advertising market size, as well as the share of intangible assets in the structure of assets and the amount of research costs. development and capital investments. The constructed scoring model was tested on the Mail.ru Group company (from 12.10.2021 — VK). Practical significance of the research results includes in the fact that the developed model can be applied not only for assessing creditworthiness, but also as one of the express methods of risk management in an organization.Предметом исследования являются компании стратегически важного в информационную эпоху IT-сектора. Их развитие связано с высокими рисками и нуждается в больших объемах инвестиций, в том числе в привлечении банковских кредитов. В этой связи цель исследования заключалась в разработке адекватной отраслевой методики рейтингования компаний IT-сектора по уровню рисков кредитоспособности с использованием математико-статистического инструментария, позволяющего достоверно оценить потенциальные риски инвесторов. Предложена методика оценки кредитоспособности IT-компаний на базе системы риск-факторов, позволяющих количественно оценить подверженность деятельности компаний двум обобщенным группам рисков: финансового риска и бизнес-рисков. На основе кластерного анализа разработана рейтинговая таблица, в соответствии с которой в зависимости от полученного расчетного балла определяется категория кредитоспособности компании. В рамках исследования сделаны выводы о том, что ключевыми факторами, оказывающими влияние на кредитоспособность компаний, являются: показатели финансовой устойчивости, рентабельность активов, коэффициент ликвидности, объем рынка интернет-рекламы, а также удельный вес нематериальных активов в структуре активов и величина расходов на исследовательские разработки и капитальные вложения. Построенная скоринговая модель апробирована на компании Mail.ru Group (c 12.10.2021 г. — VK). Практическая значимость результатов исследования заключается в том, что разработанную модель можно применить не только для оценки кредитоспособности, но и в качестве одного из экспресс-методов управления рисками в организации

Finite-dimensional reductions of the discrete Toda chain

The problem of construction of integrable boundary conditions for the discrete Toda chain is considered. The restricted chains for properly chosen closure conditions are reduced to the well known discrete Painlev\'e equations $dP_{III}$, $dP_{V}$, $dP_{VI}$. Lax representations for these discrete Painlev\'e equations are found.Comment: Submitted to Jornal of Physics A: Math. Gen., 14 page

SYNTHESIS OF BIOLOGICAL ACTIVE AZINYLFERROCENE DERIVATIVES

As a rule, the presence of a lipophilic ferrocene unit in the drug structure modulates, and often enhances, their physiological activity. In this work the synthesis of vinyl-containing azinylferrocene derivatives was presented. It was found that previously obtained by direct C-H functionalization in (hetero)azinylferrocenes 1a-d (SN H reactions) undergo regioselective Friedel-Crafts acetylation to form 1, 1'-disubstituted 2a-d products with good yields, which are able to enter the Wittig reaction to the corresponding vinylferrocenes 3a-d.This work was supported by the Russian Foundation for Basic Research, project # 20-43-660054

One-step synthesis of gold colloids using amidoaminocalix[4]resorcinarenes as reducing and stabilizing agents. Investigation of naproxen binding

© 2017 Elsevier B.V.Amido(dimethylamino) calix[4]resorcinarenes with different substituents on the lower rim (-CH3 (С1), −C5H11 (C5), −C11H23 (C11)) both as reducing and stabilizing agent in an aqueous solution were used for the fabrication of stable gold colloids. Gold colloids are characterized by spectrophotometry, FTIR − spectroscopy, transmission electron microscopy, dynamic light scattering. It is found that increase of the macrocycle's concentration towards HAuCl4 concentration during the synthesis leads to the decrease in the size of formed particles. It is shown that the size of gold nanoparticles (AuNPs) decreases with the increase of the hydrophobicity of the substituents on the macrocycles lower rim (C1@Au − 4–14 nm, C5@Au - 10–11 nm, C11@Au − 7–8 nm). The monolayer packing of the macrocycle molecules on the surface of the metal particle for C1@Au and bilayer − for C5@Au and C11@Au, providing both the stabilization of AuNPs and their solubility in water, are proposed. Temperature and pH variation during the synthesis showed that the optimal synthesis conditions for all kinds of particles C1@Au, C5@Au, C11@Au are spontaneous installed during the synthesis pH (for C1@Au − pH 8.10, C5@Au − pH 8.56, C11@Au − pH 8.63) and the synthesis temperature of the 25 °C. High binding fraction of drug substrate naproxen on the surface of AuNPs modified by C5 and C11 macrocyclic aggregates due to the ordering of the macrocycles on the particle surface and enhancing their receptor ability towards naproxen is defined by fluorescence method
