Information security risk assessment model based on computing with words
(Brno University of Technology, 2017) Tymchuk, Oleg; Iepik, Maryna; Sivyakov, Artyom; Єпік, Марина Олександрівна
The basis for company IT infrastructure security is information security risks assessment of IT services. The increased complexity, connectivity and rapid changes occurring in IT services make it impossible to apply traditional models of quantitative/qualitative risk assessment. Existing quantitative assessment models are time-consuming, at the same time, qualitative assessment models do not take into account the subjective expert assessments and the uncertainty of risk factors. This paper presents the new information security risk assessment model for IT services based on computing with words. The model methodology is based on OWASP risk rating methodology for web applications. To evaluate risk factors, it is proposed to use dictionary consisting of 16/32 granular terms (words). Problems of uncertainty in perceptual assessments of risk factors are taken into account using methods of the theory of discrete interval type-2 fuzzy sets and systems. © 2017 Brno University of Technology.

Optimal investment decision making on the model of production enterprise with limited resources
(LLC CPC Business Perspectives, 2018) Ivanenko, Tetiana; Hrushko, Viktor; Frantsuz, Anatolii; Грушко, Віктор Іванович; Француз, Анатолій Йосипович
Investments are among the most important factors of national economic growth. Selection of optimal investment project is the first priority for any enterprise with limited financial resources. This study is dedicated to a choice among mutually exclusive projects, which are impossible to complete partially, so, one project must be chosen and all others must be rejected. An investor must find among all possible projects the one that allows to better achieve all investor's aims. A mathematical model of multi-purpose multi-criteria investor decision making is proposed for investment project selection problem. Efficiency and riskiness of studied projects are evaluated using such indicators as profit, rate of return, payback period, marginal cost of capital, also taking into account subjective characteristics, namely the investor's attitude towards financial risks, importance assessment of decision making criteria, etc. Decision making assessment methods for the situations of risk and uncertainty are applied to resolve the problem of optimal project selection, such as Wald's pessimistic criterion, maximax optimistic criterion, as well as Hurwicz's, Laplace's, Bayes-Laplace, Hodges-Lehmann criteria, and Savage's minimax risk criterion. Calculations carried out and results obtained indicate that the best investment project chosen that way will provide the highest absolute profit, despite certain disadvantages such as lower rate of return, longer payback period and higher risk than other projects. © Tetiana Ivanenko, Viktor Hrushko, Anatolii Frantsuz, 2018

(LLC CPC Business Perspectives, 2018) Balatskyi, Ievgen; Andrieieva, Vita; Solodovnik, Olesia; Lypchanskyi, Volodymyr; Андрєєва, Віта Анатоліївна
In an unstable financial and economic, political and social context, a number of Ukrainian banks demonstrate downtrends in their profitability, liquidity, and solvency rates. With that, the financial health and the growth vector of the whole banking sector of the country in the strategic perspective precisely depends on the quality of measures taken to ensure the financial security of a banking institution. The article analyzes the concept of financial security of a bank from the standpoint of protective, dynamic, resource-functional, competitive and systemic approaches. The authors substantiate that the financial security of the banking system as a whole and that of an individual bank is an integral part of the financial security of the country. In addition, three methodological approaches to assessing the financial security of the country’s banking sector are identified and described, namely instrumental, system and target-oriented and criterial ones. Based on theoretical and methodological analysis of scientific works and methodological approaches, a system of research and methodological support for the bank’s financial security is proposed. © The author(s) 2019

Formation of the Stakeholders Account Model in Conditions of Sustainable Development
(Allied Business Academies, 2019) Karpenko, Lidiia M.; Koev, Stoyan Radev; Kashchena, Nataliia B.; Grushko, Victor; Khorosheniuk, Andrii; Грушко, Віктор Іванович
The world experience regarding the interpenetration of the concept of sustainable development and responsible investing and accounting models is analyzed. The drivers of the appearance of the newest accounting model are determined, taking into account the specifics of the information requests of stakeholders. The stages of transformation of key forms of traditional reporting taking into account social and environmental components are considered. The determinants and principal features of the stakeholders accounting model are investigated in order to increase the validity of investment decisions. As a result of formalization, the hypothesis that the reporting on the sustainable development of accountable investment companies constituents is more transparent than the reporting of traditional financial index companies is disproved, taking into account the sub-periods of the global financial crisis identified and the division of financial markets for developed and developing countries. This has made it possible to confirm that the disclosure of information on ESG criteria is insufficient for decision makers in the financial sector of the economy and, in turn, determine the importance of its standardization. © 2019 Allied Academies.

The paper outlines the main problems of shadowing of the labor market in Eastern Europe on the example of Ukraine and explores the factors that have a direct impact on them. A comparative analysis of the most widespread methods of tax evasion in Ukraine has been conducted. Using the software package MS Excel and CurveExpert 5.0, a study was made of the dynamics of the population employed in the informal economy during the period from 2001 to 2018; the impact of the level of labor market shadowing on the standard of living of the population of Ukraine, as well as the dynamics of the volume of remittances of labor migrants to Ukraine. The level of employment of the population in the informal sector of the economy is analyzed. It is proposed one of the alternative methods of economical and mathematical nature, with the help of which it is possible to conduct researches of the imbalance of economic systems, the construction of a mathematical model of balance on the basis of modeling of a small group using the graph theory, which will enable to carry out tactical and strategic control over the interaction of the main categories of the population in the labor market. © 2019 The Authors.
Innovative method of risk assessment of the company's economic processes
(Allied Business Academies, 2019) Bradul, Alexander; Laptev, Sergey; Shepeluk, Vira; Yunatskyi, Marian; Shypina, Svitlana; Лаптєв, Сергій Михайлович
The article defines the levels of typicality of the company's income or expenses, which arose as a result of the risk in the past, and the probable amount of future income (expenses). The Matrix of economic activity risks was built on the basis of the separation of two factors: the level of materiality and the probability of occurrence of risk; this allows determining the situations of reserves forming for repaying company losses. A form of a management report on the risks of the company has been proposed, which sets as its task to pass to all interested parties information about those risks the probability of which and the extent of damage from occurrence of which can be assessed with a sufficient degree of reasonableness. The qualitative characteristics of the company's economic risk and methods for their evaluation are also analyzed. © 2019, Allied Academies.
Spin wave modes in a cylindrical nanowire in crossover dipolar-exchange regime
(IOP Publishing Ltd, 2019) Кучко, Андрій Миколайович
Nanoscale magnetic systems have been studied extensively in various geometries, such as wires of different cross-sections, arrays of wires, dots, rings, etc. Such systems have interesting physical properties and promising applications in advanced magnetic devices. Uniform magnetic nanowires are the basic structures which were broadly investigated. However, some of their dynamical properties, like: (anti)crossing between the spin wave modes and impact of the magnetic field on the spin wave spectrum, still need to be exploited. We continue this research by investigation of the spin wave dynamics in solid Ni nanowire of the circular cross-section. We use two approaches: semi-analytical calculations and numerical computations based on the finite element method. We solve coupled Landau–Lifshitz and Maxwell equations and consider both dipolar and exchange interactions. We identify the dispersion brunches and their (anti)crossing by plotting the spatial profiles of spin wave amplitudes and magnetostatic potential. We also check how we can tune the spectrum of the modes by application of the external magnetic field and how it affects the modes and their dominating type of interaction.
Strategic priorities of intellectual capital management in the enterprise
(Allied Business Academies, 2019) Khakimov, Rashid; Abduvasikov, Abduaziz; Danyliuk, Serhii; Parshyn, Yurii; Alkema, Viktor; Алькема, Віктор Григорович
It is proved that there are many methods for measuring intellectual capital, and only their combination will lead to the most reliable data. It was determined that the intellectual capital of the enterprise is derived from intellectual resources, where resources acquire the form of capital when used and create a specific product. Therefore, the primary basis of the innovative achievements of the enterprise is intellectual resources. Outlined key characteristic features of the model helped confirm its innovative character. As experience in managing the intellectual capital of enterprises shows, the competitiveness of the latter primarily depends not on the financial and material resources it controls, but on the result of using intellectual capital, which leaves its mark on its reflection in annual reports or in separate statements of enterprises. © 2019 Allied Business Academies.
Luxury consumers’ behavior: a cross-cultural aspect
(LLC CPC Business Perspectives, 2019) Naumova, Olena; Bilan, Svitlana; Naumova, Mariia; Наумова, Олена Олександрівна
A comprehensive study of the consumers’ needs and demands, the patterns of their social and cultural behavior are essential to the success of the modern luxury companies in their market activity. The purpose of research is to study the possible differences and similarities in the perception of luxury and motivation to purchase these goods by consumers in different parts of the world and selection of acceptable marketing tools. The study is built on the results of analysis of cultural values in some countries using the country comparison tool developed by Hofstede and the results of analysis of scientific articles on the behavior of luxury goods consumers in different countries. The methodology approach – Hofstede’s model of national culture and scientific studies belonging to cultural impacts on luxury consumers’ behavior – is applied to explore cross-cultural differences in luxury consumption behavior. The findings of the study are as follows: consumers from countries with high power distance, collectivism, and masculinity, long-term orientation, and low indulgence primarily perceive social values in consuming luxury goods and are sensitive to conspicuous luxury-status. In cultures with high individualism, masculinity, indulgence, and low power distance, consumers display to perceive individual and functional values and are sensitive to “emotional hedonistic luxury.” The consumption of luxury goods in the Asian region is characterized by significant focusing on social values and status consumption, more than in the rest of the world. The motives of achievements in the form of self-realization and self-actualization are among the main reasons for the luxury consumption of European Union consumers. © The author(s) 2019.
Method for configuring the composition of a project team based on the criteria of subjective well-bein
(Technology Center, 2019) Rach, Valentyn; Osakwe, Ikenna; Medvedieva, Olena; Rossoshanskaya, Olha; Borulko, Natalia; Рач, Валентин Анатолійович; Медведєва, Олена Михайлівна; Россошанська, Ольга Валентинівна
The method for configuring a project team by the criterion of subjective well-being was developed. The method is aimed at searching for such a configuration of candidates at which a team with high commonality is formed based on the importance of values (factors) of subjective well-being and their actual satisfaction at the moment of team formation. The method is based on two conceptual provisions-axioms. Firstly, the most appropriate results of construction of a personal profile are achieved during self-analysis of the attitude of a candidate to indicators of subjective well-being. Secondly, ranking makes it possible to construct a series, in which the least achieved indicators act as the most important. On this basis, it seems possible to compare profiles of candidates with each other and identify the most similar ones. It was theoretically substantiated that the configuration of the closest profiles is a prerequisite for the formation of a positive working environment as a necessary factor for comfortable interaction of team members and a significant integrating factor of involvement in a project. The developed method of the construction of a candidate's personal profile ensures necessary accuracy and increases reliability of obtained information. Two "working zones" of a personal profile (first five and the following seven comprising 27 indicators) that determine close profiles of candidates were identified empirically. The indicators of the overall total rank for indicators of zones and the team coherence coefficient were introduced to compare the profiles. To interpret the value of coherence coefficient in the empirical way, the evaluation scale from seven interval zones for the teams consisting of two to ten participants was constructed. Its effectiveness and adequacy were proved based on the results of experimental testing, the possibility of using the criterion of subjective well-being as a parameter for the formation of project teams. © V.

Evaluation of effectiveness of responsibility centers in the management accounting system
(Allied Business Academies, 2019) Drobyazko, Svetlana; Shapovalova, Alla; Bielova, Olena; Nazarenko, Oleksandr; Yunatskyi, Marian; Бєлова, Олена Ігорівна
Evaluation of effectiveness of responsibility centers was studied on basis of reporting for different levels of management, in terms of their overall performance, which should be based on previous key indicators, which should be understood as a set (a system) of indicators both financial and non-financial, enabling managing personnel to determine the extent to which they have reached strategic and operational goals. At the same time, segregation of the appropriate types of centers of responsibility, depending on the chosen approach to implementation of management accounting at enterprises was justified. To achieve target performance indicators of responsibility centers an employee motivation system with financial and social incentives was developed aiming not only to identify contribution of certain responsibility centers in the process of accomplishing management goals, but personal contribution of each individual employee. To evaluate sufficiency of information in management reporting, a diagnostic map developed based on analysis of key indicators is proposed. © 2019 Allied Business Academies

(EManuscript Technologies, 2020) Iasechko, Svitlana; Haliantych, Mykola K.; Skomorovskyi, Vitalii B.; Zadorozhnyi, Volodymyr; Obryvkina, Oksana; Pohrebniak, Oksana; Скоморовський, Віталій Богданович
The article is devoted to the consideration of theoretical aspects of determining the possibility of concluding transactions with information. The widespread involvement of intangible assets into the real economic turnover and the emergence of a mass market for such products, combined with the “explosive” development of digital technologies, creates the conditions in which intangible assets become viable. Such development of technologies, global computerization, international trade has led to the widespread use of information, which has become one of the main and significant objects of the market and civil turnover. From the point of view of legal doctrine, the authors analyse the peculiarities of committing such transactions, outline the concepts and methodologies of civil law regulation of such relations. © 2020 EManuscript Technologies.

Structural modeling of the impact of bank nonperforming loans on the banking sector: the Ukrainian experience
(LLC CPC Business Perspectives, 2020) Bondarenko, Eugenia; Zhuravka, Olena; Aiyedogbon, John O.; Sunday, Ologunla Emmanuel; Andrieieva, Vita; Андрєєва, Віта Анатоліївна
The paper aims to develop scientific and methodological approach to assessing the interaction of nonperforming loans of Ukrainian banking institutions, the profitability of the banking sector and its financial stability, which will allow a more detailed assessment of the directions and degree of mutual influence of these elements. To substantiate this interaction economically and mathematically, structural equation modeling was chosen. Particularly, Statistica was chosen as a software tool to assess the adequacy of the resulting model and determine the level of statistical significance of its parameters. Six key indicators were selected as a research information base, two for each subject of research: indicators of nonperforming loans in the banking sector (the volume of nonperforming loans and the ratio of problem loans excluding capital reserves), profitability indicators of the Ukrainian banking sector (assets profit and rate of return on capital), and indicators of financial stability of the Ukrainian banking sector (regulatory capital-to-risk-weighted assets ratio and liquid assets-to-total assets ratio). For calculations, statistic data of selected indicators for 2005-2019 were used. As a result of calculations, mathematical data were obtained that accurately described the interaction of nonperforming loans of Ukrainian banking institutions, the profitability of the banking sector and its financial stability. The adequacy of the model was verified based on the following criteria: main summary statistics (ICSF criterion, ICS criterion, discrepancy function, maximum residual cosine), noncentrality fit indices (noncentrality parameter, population noncentrality parameter, Steiger-Lind RMSEA index, McDonald noncentrality index, adjusted population Gamma index), other single sample indices (Akaike information criterion, Schwarz criterion), and a normal probability plot. © Eugenia Bondarenko, Olena Zhuravka, John O.

(VILNIUS TECH, 2020) Podra, Olha; Litvin, Nataliia; Zhyvko, Zinaida; Kopytko, Marta; Kukharska, Liliia; Літвін, Наталія Миколаївна
The development of a knowledge economy is a key priority for innovative progress and for ensuring the country’s competitiveness through the efficient use of intellectual resources and human capital. Our paper is focused on a necessity to find out the influence of human capital in providing innovative development and the formation of knowledge economy, to develop measures for its formation, accumulation, preservation, reproduction in order to increase national competitiveness at the world market. The foundation of the knowledge economy is productive knowledge and quality education that contribute to the intellectual capital embodiment into productive activities. A detailed analysis of the current state and problems of the education and science spheres has been carried out, international ratings have been analyzed and the place of Ukraine in them is determined in the article. An estimation of financial losses of the economy in connection with the outflow of students to study abroad is hold in the article. By using the trend modeling method we propose to estimate the effect of the predicted values of the components of innovation activity on the Global Innovation Index. Results show that Ukraine position in the Global Innovation Index rating will strengthen, which can testify, about the redistribution of financing of the innovation sphere in favor of private institutions and investors. The transition to a knowledge economy involves an understanding of the decisive influence of science, the latest technologies, innovations in the global economy, and enables the resource-oriented countries to leave this status and become a countries of high-tech and high skilled development, based on the transformation of knowledge into a source of value and the driving force of economic progress. © 2020 The Author(s).
