Authors: Rosas Leutenegger Marco
Published: April 2021

El proceso de adopción de tecnologías de transporte basadas en energía eléctrica es entendido como un complejo entramado de aspectos técnicos, económicos, normativos, financieros y socioculturales. El objetivo de este trabajo fue identificar agentes, intereses, enrolamientos y dispositivos socio-técnicos específicos que se despliegan en el marco del proceso de adopción de tecnologías de transporte basadas en energía eléctrica, desde una perspectiva sistémica y territorial. Se trató de un estudio descriptivo con enfoque cualitativo, para lo cual fue revisada información secundaria y aplicadas 21 entrevistas semiestructuradas a informantes clave, seleccionados de manera intencional. Se logró constatar la emergencia de al menos 3 dimensiones empíricas, en las que se observa el despliegue de dispositivos, controversias y agenciamientos socio-técnicos: financiero-comercial, políticas público-privadas y marco normativo y científico-tecnológica. Esto llevó a concluir que una perspectiva socio-técnica con enfoque sistémico y territorial, permite hallar nuevos mecanismos de agenciamiento que influyen en el proceso de adopción tecnológica y, además permitió adelantar una propuesta de un modelo socio-técnico de carácter sistémico, con el objeto de desarrollar investigación e intervención a nivel territorial, y de esa manera realizar una contribución al diseño e implementación de políticas públicas e inversiones privadas frente al cambio climático.
Direct oral anticoagulants for prevention of stroke and other cardiovascular outcomes in patients aged 80 years or older with atrial fibrillation
Authors: Moiseev S.
Published: April 2021

Over the last decade, the number of people aged 80 years or over in Russia increased by 41% up to 5.7 mln. At least 10% of these individuals develop atrial fibrillation (AF). Treatment of rhythm disorders in the very elderly patients is challenging due to the high occurrence of comorbidities, including cognitive dysfunction, changes in the pharmacokinetics of drugs as a result of reduced kidney function, increased risk of interaction of drugs. The very elderly patients with AF have a higher risk of ischemic stroke and other cardiovasculat outcomes, including myocardial infarction, and should be treated with oral anticoagulants. The results of randomized controlled trials and prospective and retrospective observational studies suggest that in patients aged 80 years or older with non-valvular AF direct oral anticoagulants (DOAC) are at least as effective as vitamin K antagonists for prevention of ischemic stroke and are associated with a lower risk of intracerebral haemorrhage. The use of DOAC (once daily rivaroxaban in particular) impoves compliance to anticoagulation in the very elderly patients with non-valvular AF.

Published: April 2021

The households’ savings in Malaysia have shown a deteriorating trend that negatively impacts their financial security. The Financial Inclusion and Capability Study of BNM (2016) indicates that merely 6 percent of Malaysians could survive for more than six months and 18 percent up to three months if they lose their main source of income. Thus, it is imperative to examine the drivers of future savings of Malaysian households. A sample of 1,106 bank customers in three cities of peninsular Malaysia was recruited, and the descriptive statistics, correlation analysis, and Seemingly Unrelated Regressions (SUR) were employed. The results reveal that about 25 percent of households are not likely to make any changes in their savings profile in various financial and physical assets. The drivers of future saving are found to be socio-demographic parameters, such as age, education level, the number of working members in the household, and income, and other parameters, such as the percentage of income saved, and the period of the saving plan, which have a significant relationship with the change in future savings of the households. The policy implications of the findings are also presented.
EFFECT OF FOREIGN INVOLVEMENT ON CORPORATE TAX NONCOMPLIANCE
Authors: Suleiman Salami
Published: April 2021

There exists a potential decline in tax revenue to government among firms with foreign involvement. The main aim of the study is to examine the impact of foreign involvement on corporate tax noncompliance. The study focuses on the effects of foreign CEO, the percentage of foreign executive board members, and the ratio of stocks owned by foreign directors on corporate tax noncompliance. Data on manufacturing firms were utilized based on data availability from 2015 to 2019. Generally accepted accounting principle effective tax rate was utilized as a primary measure of tax noncompliance and fixed effect technique of regression analysis. Controlling for profitability, leverage, firm size and board size, the findings of the study revealed a significant negative effect of the percentage of foreign executives’ shareholding on GAAP ETR. Our result is robust to using cash effective tax rate as an alternative proxy for tax noncompliance. The implication of this finding is that an increase in foreign executive shares will reduce tax proceeds. Given the corporate tax implication, regulatory authorities should weigh the cost and benefit of a benchmark for foreign directors’ equity ownership.
THE EFFECT OF ECONOMIC GROWTH AND HUMAN DEVELOPMENT INDEX ON POVERTY IN INDONESIA
Authors: Hasan Zulfikar
Published: April 2021

Indonesia’s economic growth, which ranges from 5% - 6% per year, apparently has not been able to reduce the number of poor people. There has even been an increase in the total of poor people, which is currently around 37 million people. A World Bank study shows that almost 50% of Indonesia’s population is categorised as “poor” and “on the verge of poverty”. The problem of poverty deserves significant attention from all parties. Economic growth accompanied by an increase in the number of poor people is certainly inviting several questions, such as who is enjoying the economic growth and whether the economic growth is caused by increased productivity or the use of factors of production, etc. In Indonesia, economic growth seems to be concentrated in specific sectors, while some other areas have relatively slow growth that poverty reduction is difficult. Hence, research on economic growth, human development, and poverty levels in Indonesia is warranted. The results are expected to explain the phenomenon of increasing poverty in Indonesia.

Published: April 2021

The article is aimed at the theoretical generalizing and systematizing the risks of industrial enterprises in the context of the COVID-19 pandemic. The essence of the concept of «risk» is analyzed and the need for its estimation in the context of the COVID-19 pandemic caused by the SARS-CoV-2 virus is specified. The main classification features of risks in the activity of industrial enterprises are considered. The state of Ukraine’s industry in 2020 is examined and it is concluded that as a result of the coronavirus crisis it is in a difficult situation. A number of risks are identified and their negative impact on the activities of industrial enterprises in Ukraine, both in quarantine and in post-quarantine conditions, is characterized. Among them are: financial-economic, international, commercial, industrial, and social risks. The expediency of application for the estimation of determined risks of statistical, expert, accounting-analytical, analytical, economic and statistical methods, as well as methods of analogues, sensuality, scenarios, Monte Carlo, is substantiated. Given the uncertainty of the time frame associated with the duration of the coronavirus pandemic, it is proposed to constantly monitor risks in order to improve the situation in the sphere of industry, which will allow timely detection of weaknesses and identification of the negative manifestation of crises in various industry sectors. Prospects for further research in this direction are the development of a mechanism for managing and reducing the negative impact of identified risks on the activities of industrial enterprises in both quarantine and post-quarantine conditions, as well as outlining the instruments for ensuring the positive effect of the proposed mechanism.

The article is aimed at elaborating a conceptual model for the gradual transition of sanatorium-and-resort complex (SRC) enterprises to self-supporting principles of doing business, as well as proposals and practical recommendations as to the preparation of strategic tasks for their development. A sanatorium-and-resort institution as an enterprise that makes the transition to market conditions of management and must implement self-supporting mechanisms in the process of providing health improvement services is analyzed. The priority business tasks of sanatorium-and-resort enterprises are identified, their current business policy is characterized. Both the domestic and the foreign experience as to organization of the commercial component of recreational enterprises is analyzed. The reasons for the inhibition of business processes in domestic sanatorium-and-resort enterprises are identified, i.e.: shortcomings in the public sector of the SRC management, but, to a greater extent, the lack of readiness of the enterprises themselves to work in the market conditions (slow reorientation to «innovative thinking» and entrepreneurship, lack of business experience, shortcomings in information support, etc.). The structural model of formation of business strategy for the development of enterprises of sanatorium-and-resort complex is built up, which reflects the transition of the sanatorium-and-resort complex to a new economic model of management and contains such main blocks as innovative thinking, entrepreneurship, activation mechanisms, business organization. Recommendations on intensification of commercial activity in the research sphere have been elaborated and proposed.

The article is aimed at exploring the gender features of the labor market in the context of the COVID-19 pandemic, along with the impact of quarantine restrictions caused by the introduction of anti-epidemic measures to counteract the spread of coronavirus disease in Ukraine, on the existing balance of gender equality in Ukrainian society. The identified gender inequality manifestations in the labor market have intensified and received negative dynamics during the COVID-19 pandemic. Quarantine restrictions and the limited activities of enterprises in the sphere of trade, culture, art, education, hotel business and others, in the structure of employment of which the women’s labor force prevails, have caused an increase in the number of unemployed and a decrease in the social protection of employees involved in these sectors. An increase in the wage gap between women and men during the period of quarantine restrictions both by type of economic activity and by region is identified. The proposals and recommendations are directed towards: taking into account gender needs in overcoming the consequences of the COVID-19 pandemic; reducing gender inequality and injustice in employment and income; ensuring support for political activity of the female population, involvement in decision-making in the life of both the community and the State; strengthening liability for direct or indirect discrimination and gender inequality; taking into account in the programs of socio-economic development of territories of gender needs as to different age groups; introduction of training aimed at ensuring gender approach and gender equality in organizations and enterprises; financial, economic, legal and educational support for the development of women’s business. Prospect for further research in this direction is to determine the impact of the existing level of gender equality and the structure of employment by gender in the sectors on the possibilities of economic development of the country.

This study is aimed at increasing the efficiency of multimodal freight transportations by forming a risks management system based on the identification of transport risk factors, methods of their measurement and management both at the projecting (planning) stage of the multimodal route and further on – in order to assess their possible impact on the efficiency of freight transportation in general. The authors examine the problematics of multimodal freight transportations organization in the context of transport risks management, which provides for the choice of such an option of management influences on elements of the transportation system (logistics centers, transport hubs, various types of transport, freight transport units, specific transport companies and their rolling stock, containers, etc.), in which freight delivery would be carried out in terms of the most efficient and qualitative indicators under the known initial conditions and existing restrictions. The article substantiates the proposals development in view of optimal relationships between elements of multimodal freight transportations on the basis of an efficient risks management system, which is a special type of management activity directed towards mitigating the influence of risk groups, determining the permissible (acceptable) level of risk based on methods that allow avoiding losses arising as result of a particular risk. A methodical approach to choosing the optimal multimodal transport-technological scheme is proposed, which allows considering subjective criteria (completeness of service, reliability, etc.) as decisive under the condition of relatively equal cost and time of alternative freight delivery options and in the context of permissible values of such objective criteria as storage conditions, high-speed mode of transportation in the territory of a particular country, region, city, axial load, climatic conditions, ecological restrictions, etc. At the scientific-methodological level, the stage of the decision-making process is generalized along with the separation of relevant goals in the context of managing transport risks in multimodal freight transportations, the observance of which will guarantee to ensure the acceptance by the operator of multimodal transportations of a rational and secure transport-technological scheme of freight delivery.

The article is aimed at applying the Franchon and Romane matrix at the food industry enterprise within the terms of a comprehensive analysis of the enterprise’s financial sustainability and equilibrium. Analyzing and systematizing the scientific works of many scholars, the evolution of approaches to the financial strategy of enterprise was considered and it was specified that the construction of the matrix of strategies according to Franchon and Romane makes it possible to respond timely to the need to change the financial strategy depending on the change in the conditions of its activities. To achieve the goal, the research had to solve the following tasks: determining the algorithm for calculating the financial indicators of the matrix; their calculation for the last five years of activities of the researched enterprise; determining on their basis the type of financial strategy; determination of factors influencing financial strategies; development of measures to improve the financial condition by changing the financial strategy. The object of research is PrJSC «Vinnytsia confectionery factory» («Roshen»). The matrix analysis of the company’s activities for 2015-2019 allowed to determine the further trajectory of the enterprise’s development. The indicators of economic activity of the enterprise led to an increase in financial potential, but at the same time there is an obvious limitation of the current development strategy. The obtained results as to determining the financial strategy are justified by a preliminary analysis of the financial condition. The application of the strategy matrix enables the enterprise to make the right decisions on the complex use of all financial resources aimed at achieving both the current and the strategic goals in a timely manner. Prospects for further research are to determine the impact of the quality of the company’s cash flow management on its liquidity and solvency.

Published: April 2021

The article is aimed at forming a methodical approach to the assessment of tendencies in production, sales and organization of consumption of food products and services, which includes all the components of the food sector and allows to conduct a comprehensive assessment of tendencies in its development. The proposed methodical approach includes assessment of the status and dynamics of food supply to the population, assessment of the status and dynamics of indicators of agricultural enterprises, food industry, trade in foods, restaurant economy and assessment of the factors that influence the development of the food sector. The use of the proposed methodical approach allows to reasonably make decisions on the development of a strategy for the development of food sector enterprises. The conducted studies have shown that in Ukraine as a whole and in its regions in particular in recent years there have been positive tendencies in the production, sale and organization of consumption of food products and services. At this, sales of foods by enterprises of both agriculture and food industry is much higher than by retail enterprises of food products and restaurant enterprises, which indicates the sufficient provision with food products to the financially reliable demand of the population of Ukraine. Prospects for further research in this direction are the development of methodical instrumentarium for assessing the effectiveness of management of food sector enterprises, which will be adapted to modern conditions for the implementation of specific managerial decisions.

The article discusses the defining competitive advantages of food retail stores. It is defined that the competitive advantages that determine the level of competitiveness of production and trade enterprises do differ. The main competitive advantages of trading enterprises are their location, product range, pricing policy and quality of service. As a result of the analysis of the trade infrastructure of the city of Lviv, it was concluded that there were problems in shaping the competitiveness of small forms of retail trade in food products, which are associated with the active development of national retail chains and the emergence of international trade operators in the market. The classification of stores by the signs of the size and territory of the girth was carried out. The peculiarities of their competitive advantages are determined. It is identified that the emergence of networks of the latest large formats of stores with the possibility of purchasing goods at lower prices was a threat to the functioning of traditional stores «close to home» and the reason for the decrease in their number. A comparative analysis of advantages and disadvantages of small forms of retail and large retail is carried out. The main competitive advantages of small retail stores are the proximity of the location to the buyer and trusting relationships with regular customers. The price, product range and possibilities of implementing loyalty programs are identified as the main strategic competitive advantages of large store formats. The emphasis on these advantages makes it possible to effectively manage the competitiveness of retail.

The article explores and analyzes the problem of gender equality among cadets and students of higher educational institutions, in particular aviation and technical. The appropriate methods and main aspects of solving the problem are defined. In addition, various methods for introducing gender equality into the educational process are provided and the relevant work of the teacher during classes is presented. At present, gender equality among cadets and students of aviation and technical universities is an urgent problem in Ukraine, because the humanization and democratization of modern society envisage the orientation of our State towards establishing universal human truths and standards. First of all, gender theory should be integrated into the system of scientific knowledge and educational disciplines. Educators should implement planned educational activities aimed at identifying and neutralizing gender stereotypes that form the basis for non-compliance with gender parity and discrimination. Thus, teachers should ensure gender equality among students of higher educational institutions, including cadets and students of aviation and technical higher educational institutions. It is also worth noting that observance of human rights is being formed as a certain ideal, the main means for which is the achievement of the general principles of law, and its fundamental principle is the multi-aspect principle of gender equality. However, given the aforesaid matters, equality of genders does not mean only their biological identity or ignoring physical capabilities along with the mental and psychological characteristics. On the contrary, differences should not be negatively reflected in the living conditions of both men and women, thereby causing discrimination.
Progresywność europejskich systemów emerytalnych - ujęcie porównawcze
Authors: Rutecka-Góra Joanna
Published: April 2021

Pomiar redystrybucji jest zadaniem niezwykle skomplikowanym, gdyż transfery emerytalne mają charakter indywidualny. Dla dokładnego określenia ich poziomu i kierunków niezbędne są dane charakteryzujące okres opłacania składek a następnie wypłaty świadczeń dla każdego uczestnika systemu emerytalnego. Tylko takie podejście gwarantuje dokładne wskazanie kierunków redystrybucji i oszacowanie poziomu transferów na rzecz określonych grup beneficjentów. Szczegółowe informacje na temat przepływów emerytalnych nie są zwykle dostępne w większości krajów, stąd nie mogą zostać wykorzystane w porównaniach międzynarodowych. Analizy komparatywne progresywności systemów emerytalnych muszą się zatem z konieczności opierać na pewnych ogólnych i przybliżonych miarach, które często nie uwzględniają szczególnej specyfiki funkcjonowania krajowych systemów emerytalnych. Ocenę progresywności utrudniają dodatkowo odmienne warunki ekonomiczne i społeczne, konieczność przyjmowania szeregu założeń, które mogą być obarczone istotnymi błędami (m.in. w zakresie stopy zwrotu z inwestycji, stopy wzrostu wynagrodzeń, stopy inflacji i dalszego trwania życia). W niniejszym artykule podjęto próbę oceny stopnia progresywności systemów emerytalnych w wybranych krajach Unii Europejskiej w oparciu o oficjalne dane gromadzone i publikowane przez Eurostat. Z uwagi na ograniczenia w dostępie do danych i brak możliwości oszacowania standardowych wskaźników progresywności, zaproponowano i obliczono alternatywne indeksy progresywności opierające się na współczynnikach Gini’ego nieuwzględniających transferów socjalnych oraz współczynnikach pomijających transfery socjalne lecz uwzględniających świadczenia emerytalne. Alternatywne wskaźniki progresywności posłużyły w identyfikacji krajów, w których prawdopodobnie występuje relatywnie silna lub słaba redystrybucja. Do pierwszej grupy należą m.in.: Grecja, Szwecja, Niemcy i Czechy, natomiast do drugiej: Irlandia, Cypr i Hiszpania. Uzyskane wyniki są jedynie symptomami możliwej redystrybucji, gdyż alternatywne wskaźniki progresywności bazują głównie na poziomie świadczeń emerytalnych i ich zróżnicowaniu w populacji, nie uwzględniając etapu gromadzenia praw emerytalnych. Dokładne określenie poziomu transferów redystrybucyjnych w systemach emerytalnych wymaga szczegółowej analizy formuł emerytalnych i zasad opłacania składek.

Authors: Hudomalj Uroš , Mandla Christopher , Plattner Markus
Published: April 2021

This paper presents FPGA implementations of image filtering and image averaging – two widely applied image preprocessing algorithms. The implementations are targeted for real time processing of high frame rate and high resolution image streams. The developed implementations are evaluated in terms of resource usage, power consumption, and achievable frame rates. For the evaluation, Microsemi’s Smartfusion2 Advanced Development Kit is used. It includes a SmartFusion2 M2S150 SoC FPGA. The performance of the developed implementation of image filtering algorithm is compared to a solution provided by MATLAB’s Vision HDL Toolbox, which is evaluated on the same platform. The performance of the developed implementations are also compared with FPGA implementations found in existing publications, although those are evaluated on different FPGA platforms. Difficulties with performance comparison between implementations on different platforms are addressed and limitations of processing image streams with FPGA platforms discussed.
Customer Choice Modelling: A Multi-Level Consensus Clustering Approach
Authors: Pasquier Nicolas , Chatterjee Sujoy
Published: April 2021

Customer Choice Modeling aims to model the decision-making process of customers, or segments of customers, through their choices and preferences identified by the analysis of their behaviors in one or more specific contexts. Clustering techniques are used in this context to identify patterns in their choices and preferences, to define segments of customers with similar behaviors, and to model how customers of different segments respond to competing products and offers. However, data clustering is an unsupervised learning task by nature, that is the grouping of customers with similar behaviors in clusters must be performed without prior knowledge about the nature and the number of intrinsic groups of data instances, i.e., customers, in the data space. Thus, the choice of both the clustering algorithm used and its parameterization, and of the evaluation method used to assess the relevance of the resulting clusters are central issues. Consensus clustering, or ensemble clustering, aims to solve these issues by combining the results of different clustering algorithms and parameterizations to generate a more robust and relevant final clustering result. We present a Multi-level Consensus Clustering approach combining the results of several clustering algorithmic configurations to generate a hierarchy of consensus clusters in which each cluster represents an agreement between different clustering results. A closed sets based approach is used to identified relevant agreements, and a graphical hierarchical representation of the consensus cluster construction process and their inclusion relationships is provided to the end-user. This approach was developed and experimented in travel industry context with Amadeus SAS. Experiments show how it can provide a better segmentation, and refine the customer segments by identifying relevant sub-segments represented as sub-clusters in the hierarchical representation, for Customer Choice Modeling. The clustering of travelers was able to distinguish relevant segments of customers with similar needs and desires (i.e., customers purchasing tickets according to different criteria, like price, duration of flight, lay-over time, etc.) and at different levels of precision, which is a major issue for improving the personalization of recommendations in flight search queries.

Task. This article examines the threats and risks of the spread of new digital currencies, in particular stablecoins. Digital currencies are classified, their advantages and disadvantages are indicated. In particular, the article reveals the types of stablecoins and the issues of their regulation. The advantages of stablecoins over cryptocurrencies and virtual currencies are also noted. Summary. Taking into account advantage of stablecoins and disadvantages of other digital currencies, it can be predicted that this type can become one of the most common types of digital currencies. However, this could potentially have a potential shift in the virtual asset ecosystem as well as in the global economy. The proliferation of stablecoins introduces new risks and threats in the area of money laundering and terrorist financing. The regulation of these digital currencies is a topical issue for the FATF, as well as for national FIU structures. Disclosure of these issues is being considered in accordance with the draft law «Law on Cryptocurrency 2020» and amendments to the FATF Recommendation 16, called «Travel rule» for cryptocurrency.

Published: April 2021

The article analyzes the problems of technological development of Russia in the context of world economic integration and the resulting threat-forming factors of economic security and financial sovereignty of Russia, the source of which is the investment and credit sphere. Global financial integration creates new risks for Russia's monetary policy, limiting the space for its independent implementation, and destroys the country's economic, including financial, sovereignty. For Russia, with its huge natural resources and companies that correspond to them in size, the issue of concentration of bank capital is extremely relevant - only its own large banks are able to provide financial sovereignty and financial needs of the developing Russian economy, including the needs of the emerging sector of development and technology implementation.
