Eastern Regions in the Economic Strategy on the “Take-off” Stage of the Soviet Industrial System

The article delves into the strategy and implementation of economic development in the eastern regions of Russia from the pre-war five-year plans to the “Kosygin reform”. It highlights the substantial growth in the importance of these regions in the national economy during this period. However, historical perspectives on the long-term consequences of the “Eastern shift” in the production and population proportions vary. Some researchers believe that such a course met and meets the fundamental interests of the country. Others dispute this, attributing it to excessive geopolitical ambitions and a distorted understanding of the economy’s actual needs. Based on the historiographic analysis and documentary sources, the author offers an interpretation of why the authorities prioritized the advanced economic development of the eastern territories and how they executed this strategy. It is concluded that implementation of such a course has led to a radical change in the territorial structure of production. At the same time, as the period under review drew to a close, the focus shifted from advanced development to sustaining the achieved level, resulting in a deceleration of economic growth in the eastern regions. This was primarily ascribed to the decreasing efficacy of the “socialist economic system” and the ruling elite's persistent aversion to reforming economic institutions. One overarching argument posited in the article is that there was a substantive “shift of productive forces” towards the East in the broader context of the Soviet era, coinciding with the period of the “take-off” of the Soviet industrial system. The foregoing allows us substantiating the relationship between high rates of economic growth and “intensive economic development” of the eastern regions of the country.

Self-transcendence: Design Criticism in the 1928 Shanghai Exhibition of National Products

Abstract After establishing the Shanghai port in 1843, Western machine-made products inundated the Chinese consumer market, disrupting the local Chinese economic system. To foster the advancement of national industries, the Nanking nationalist government held the Ministry of Industry, Commerce, and Labour’s Exhibition of National Products in 1928, providing a platform for public discourse on the design of national products. This article analyses the progression of three representative types of early design criticism that emerged from the Exhibition of National Products. These criticisms examined the design’s economic benefits, responsiveness to cultural needs, and influence on shaping social consensus. Their progressive development can be characterized as a form of self-transcendence, indicating a move by critics beyond past limited understandings of the value, sphere of influence, and design’s role in society. Their focus transitioned from the economic interests of minorities to the diverse needs of broader social groups. In the process of self-transcendence, these design criticisms expanded the horizons of designers’ work. They facilitated collaborations between design and various industries, including production, consumption, and education, influencing broader socioeconomic and ideological fronts.

Sustainable Development Challenges in Shanxi's Coal Industry: A case study of Datong Coal Mine Group

The purpose of this study is to investigate the sustainable development challenges faced by coal resource-based areas, focusing specifically on Shanxi Province in China. The study aims to understand the long-term impacts of extensive coal mining on the ecological environment, safety incidents, and the local economic system. It seeks to draw lessons from case studies of coal enterprises to identify innovative measures for companies in transition and development, with the ultimate goal of promoting sustainable practices that address livelihood issues and contribute to the modernization process. The research employs a qualitative case study methodology, using Datong Coal Mine Group in Shanxi Province as a representative example. This approach enables an in-depth analysis of the specific challenges related to coal mining in the region. The findings highlight the significant ecological and safety challenges posed by widespread coal mining practices in Shanxi Province, including environmental degradation, ground subsidence, and recurring safety incidents. The study suggests a need for innovative measures to transition towards more sustainable and diversified economic activities. The research provides valuable insights and recommendations for policymakers, industry leaders, and communities in similar resource-dependent regions to adapt to the demands of modernization and sustainability.

Relationship between Residential Patterns and Socioeconomic Statuses Based on Multi-Source Spatial Data: A Case Study of Nanjing, China

The relationship between residential patterns and socioeconomic statuses highlights the complex interactions between the economic regime, welfare system, and neighborhood effects, which are crucial in urban inequality studies. With the diversification of the housing demand and supply system, the traditional analysis conducted separately from the ethnic or spatial segregation perspective fails to capture the rising inequalities and changing socio-spatial context. Taking Nanjing as an example, based on a multi-source database including the housing price, residential environmental quality, surrounding support facilities, and mobile phone user portrait data, this paper proposed a modified method for discovering the coupling relationship between residential patterns and socioeconomic statuses. It is found that socioeconomic status contributes to residential spatial aggregation and that the relationship between social and spatial dimensions of residential differentiation is tightly coupled and related. The lower socioeconomic strata were displaced to the periphery and the older urban core, while affluent inhabitants were more likely to settle voluntarily in segregated enclaves to isolate themselves from the general population through more flexible housing options. The heterogeneity of the urban socioeconomic dimension is primarily affected by consumption and occupational status, while housing prices mainly determine the divergence of spatial distribution.

Evolution of the Concepts of “Financial Architecture” and “Financial Architectonics”

The development of financial markets and institutions has led to the complexity of financial systems, which in turn requires new approaches to their analysis and management. In this context, the concepts of “financial architecture” and “financial architectonics” are of particular importance. However, despite the widespread use of these terms in the scientific literature, their interpretation is often ambiguous and controversial. The purpose of the study is to examine the evolution of the essence of the concepts of “financial architecture” and “financial architectonics”, to identify their differences and interrelationships, and to formulate own definitions of these terms, taking into account modern approaches and trends in financial science. To achieve this goal, a number of theoretical methods were used, namely: monographic - for reviewing scientific publications related to the concepts of “financial architecture” and “financial architectonics”; comparative analysis - to identify the differences and common features between the concepts of “financial architecture” and “financial architectonics”, which allowed to formulate the main characteristics and relationships between these definitions; the method of systematic approach - to study the relationships between the elements of the financial system and their structuring, which allowed to consider financial architecture and financial architectonics as integrated concepts with certain characteristics and interactions; the method of historical analysis - to study the evolution of the concepts of “financial architecture” and “financial architectonics”, which allowed to trace changes in the definitions and approaches to these terms in the context of the development of financial science; the method of conceptual modeling - based on the generalization of the data obtained and the analysis of current trends in the financial sector, the author proposed her own definitions of the concepts of “financial architecture” and “financial architectonics”. Financial architecture is defined as a structured model that covers the regulation and management of financial components at the macro-, meso-, and micro-levels of the economic system, and financial architectonics is defined as a comprehensive concept that reflects the structure and interrelationships between the elements of the financial system. The distinction between these concepts allows for a deeper understanding of various aspects of financial management. Financial architectonics offers a broader view of the financial system, taking into account complex interrelationships and dynamic processes, while financial architecture focuses on specific structural components and their regulation.

СУТНІСНА ХАРАКТЕРИСТИКА РОЗВИТКУ ПІДПРИЄМСТВА

The article is devoted to the study of the essential characteristics of the development of socio-economic systems in general and the enterprise, in particular. Attention is focused on the dependence of the perception of development and economic conditions in the country's economic system. A philosophical approach to the "development" category is presented. Because of the research of the views of domestic scientists, emphasis is placed on the main such feature as objective changes in the qualitative characteristics of the system. At the same time, three main directions of changes are highlighted - quantitative, structural and qualitative - which are clearly correlated. Other approaches to the concept of "development of the enterprise" are considered, which accordingly focus on: its acquisition of new opportunities and properties, qualities and characteristic features; quantitative changes in the system due to the process of transition to a new, higher quality state. The results of the study of various approaches of domestic scientists and their generalization made it possible to single out four differentiated groups of views on the economic context of the concept of "enterprise development", which are structured in the form of a table. A separate aspect of the consideration of this article is the main laws of the development of the economic system, on which the concept of enterprise development is based. These are the laws of unity of analysis and synthesis, development, stability, synergy, awareness, composition and proportionality. Based on the analysis of synonymous concepts, such as "organizational development" and "organizational development of the enterprise" and others, three main aspects of development are emphasized: scientific and technical, market and organizational. The importance of managing the development of the enterprise as a cyclical process of managing qualitative and quantitative changes in the organization with appropriate information support aimed at increasing the efficiency of the enterprise in the long term is emphasized. It was concluded that development is an integral process of the existence of any socio-economic systems and requires constant control and management by management.

ФОРМУВАННЯ НА СУЧАСНОМУ ЕТАПІ РИНКУ ФІНАНСОВИХ ТЕХНОЛОГІЙ В СВІТОВІЙ ЕКОНОМІЦІ

The current stage of development of the world economy is characterized by the process of increasing the role of the financial sector, as well as the transition to a new phase of development - innovation. Globalization in financial innovations is critical in international innovative development in today's conditions. The rapid spread of financial innovations under the conditions of financial globalization has become the main driver of the formation of the world economic system, contributing to the deepening of financial globalization. The formation of the financial services market is uneven because various factors influence it, including the level of development of information and communication technologies, the stability of the financial sector, and others. These factors have been studied by researchers, but the development of specific segments of the fintech market has its peculiarities. Fintech is a complex system that unites the sectors of new technologies and financial services, startups, and the relevant infrastructure. The financial services sector is increasingly actively using new technologies and tools to perform its functions and implement fundamentally new solutions in which consumers of services are interested. New technologies inherently changed not only the historically formed landscape of providing financial services, giving it freshness and dynamics, but also changed the attitude to such a concept as "money", realizing the transition from cash to virtual money in a reasonably short period. The industry provides subjects of financial relations with a wide range of innovative technologies, among which robotics, biometrics, remote banking, P2P lending, and many others have become vital. The fintech industry is expected to grow due to increased market penetration rates for existing services and their international expansion. The transition from the traditional financial services system to a digital one provides excellent opportunities for large financial companies and FinTech startups to work with banks or financial organizations. As more critical financial infrastructure projects come into production, more players will be interested in implementing digital financial technologies.

ВПЛИВ ВІЙНИ НА МІЖНАРОДНІ ТРАНСПОРТНІ ПЕРЕВЕЗЕННЯ УКРАЇНИ

The article found that the full-scale war in Ukraine had a strong impact on international transportation. The structure of the volume of cargo transportation and the number of transported passengers were analyzed. It was determined that there is uncertainty in the market of international freight transportation of Ukraine during the studied period. On the one hand, the war had a negative impact on the country's economy and led to a decrease in the volume of cargo transportation. On the other hand, Ukraine is an important transit country through which key logistics routes connecting Europe and Asia pass. It was established that the blocking of air transport and sea trade, with the exception of the "Grain Initiative", led to a radical change in the structure of domestic import/export and the leadership of land corridors. Global transformations in world trade caused by the war in Ukraine also affected the configuration of existing supply chains, Ukrainian exports were completely reoriented towards the EU. It is indicated that Ukraine's signing of an agreement on visa-free transport cooperation with the European Union has opened up new prospects for bilateral international road transport, freeing Ukrainian carriers from the need to obtain permits for flights to EU countries. However, there are also negative trends that affect the growth of transport services and, as a result, decrease the competitiveness of transport companies. A list of legislative and regulatory innovations and organizational measures aimed at improving international transportation is given. It is argued that a successful solution for the recovery of the country will be the integration of the Ukrainian economy into the EU economic system with the help of various European logistics and infrastructure projects. It was determined that the key factors in the normalization of transportation were: the conclusion of the "Grain Initiative" with the UN and Turkey, which allowed to unblock the ports of Great Odesa; signing the Agreement on the Liberalization of Road Freight Transportation with the EU; development of border infrastructure, in particular, increasing the capacity of existing road and railway checkpoints, as well as the opening of new ones; increasing cargo handling in the ports of the Danube port cluster.

The Economic Effects of Globalization on Developing Countries

Globalization is the dramatic change in the world economy, a situation in which across the border exchange activities and economic integration are becoming more intense between nations across a worldwide economic system. The paper discusses the multifaceted faces of globalization pressure on developing countries and identifies key benefits that result from such growth, as well as significant challenges. It illustrates how technology development, improved communication, and growing international trade are some of the more obvious drivers of globalization, as well as bring out the complex interface between global forces and local conditions. The main focus of this research is to present a comprehensive review of the negative and positive impacts of globalization on developing nations. The study epitomizes the enormous benefits accruable from increased market access, foreign direct investment, transfer of technology, and improvement in living standards. Opening to larger international markets helps the developing countries to diversify their economies and accelerate growth. For instance, both China and India use globalization to achieve high rates of economic growth by increasing trade and investment opportunities. It has also made vital capital and technological expertise available and has promoted much-needed industrialization and productivity enhancement. Technology transfer has enabled developing nations to step into the modernization of their industry for a more productive integration of the country into global value chains. This, in turn, will enable them to achieve higher economic growth rates and an improved standard of living. Despite such positive contributions from globalization, there are still some challenges that come along and really inhibit development. It addresses crucial backwardness, including increasing income disparity, high vulnerability to external economic shocks, and environmental degradation. In as much as globalization may result in economic growth, the accruing benefits are usually distributed very unequally, and often heighten disparities between urban and rural areas, thereby occasioning social tensions. Developing countries that are heavily dependent on exports or foreign investment may face severe economic instability during a global financial crisis. These impacts were clearly felt in most developing economies when the global financial decline occurred in 2008. Their quests for economic growth, however, have often been accompanied by unsustainable practices that bring with them environmental degradation in the form of deforestation, pollution, and the depletion of resources. Considering these benefits and challenges of globalization, some recommendations in the study for developing countries include:. These comprise domestic institution building to manage the increased complexities from globalization, investment in education and skills development to improve human capital and reduce job displacement, sustainable practices that reduce environmental impacts, and inclusive growth that allows the fruits of globalization to be equitably distributed. This will enable developing nations to manage the increased complexities from globalization and ensure sustainable economic development for their citizens. This study, in short, tried to reflect on various dimensions of globalization concerning developing countries, explaining how these could unleash economic growth, while their challenges naturally came with the process. Grasping these dynamics is crucial for policy makers, researchers, and stakeholders who seek to capitalize on the opportunities of globalization so that its fruits are equitably distributed and the negative impacts well mitigated.

Value model of political communications of the Russian elite in conflictual and deviant polysubject environment

The article, based on the results of a comprehensive political analysis, substantiates that in the modern socio-political reality, the formation of a multipolar world, the problem of the effectiveness of political communications are closely related to the potential of political and administrative power elites. The communicative qualities of a modern politician are enhanced by value-civilizational and moral parameters, the ability of strategic vision and the ability to maintain civilizational and value discourse in the political and economic system and direct it towards sustainable advanced development of society. This, in turn, involves the analysis and development of parameters for diagnosing the quality of modern Russian political and administrative elites, their moral and professional adequacy and aptitude; so is the actualization and solution of the problem of deviations at the elite level of political power. In order to form a value model of political communications of the Russian elite, it is necessary to comprehensively consider management systems based on specific values (including management of public values), identify and position public values as determinants of socio-political development, develop mechanisms to counteract the value degradation and marginalization of national elites, take into account the propensity of the Russian government to identify internal and external enemies in the previous stages of development, and also to the uncritical borrowing of the models of democracy alien to the Russian cultural and civilizational code, and the image imitation of elite qualities.

A brief discussion on the coupling principle of positive and negative feedback in the economic system

This study clarifies the concepts of “feedback”, “positive feedback”, and “negative feedback” and explains the philosophy of the coupling principle of positive and negative feedback. The evolution process of the system is the organic coupling of positive and negative feedback, and only the reciprocating cycle of positive and negative feedback can ensure the occurrence and existence of heterogeneous new things. In the economic system, the law of increasing returns corresponds to the positive feedback mechanism, whereas the law of diminishing returns corresponds to the negative feedback mechanism. This study briefly expounds on the differences in understanding between the law of increasing returns and diminishing returns, and the equilibrium and disequilibrium of economic operation in the economics circle, based on the histories of economic thoughts and social and economic forms. This study emphasizes that instead of dividing and opposing each other, the idea of static partial equilibrium and dynamic general nonequilibrium in epistemology can be united to solve this difference. Finally, this paper explains the essential relationship and compatibility between the law of diminishing returns and increasing returns from the characteristics, nature, and proportional changes of tangible and intangible factors of production. Applying the positive and negative feedback coupling principle can clarify the essential relationship between the law of diminishing returns and increasing returns. From the philosophical level and epistemological significance, it can bridge the fundamental differences between equilibrium and nonequilibrium theories, which in turn, can help realize the creative synthesis of economic theory.

Feasibility Study of an Integrated Waste Management Technology System for a Circular Economy in the Philippines

Increasing population and rapid economic growth result in waste management problems in the Municipality of Bay, Laguna. In response, the municipality is planning to invest in an Integrated Waste Management Technology System (IWMTS) that aims to generate public revenue. Key informant interviews, surveys, and focus group discussions were utilized for data collection. Results showed that respondents lack knowledge about IWMTS but perceive positive impacts on waste volume reduction and municipal waste management and little to no negative impacts on health, livelihood, and accessibility. Meanwhile, economic analysis showed that it is estimated to generate an annual revenue of PHP 11.986 million (USD 214,036) with yearly expenses of PHP 3.7 million (USD 66,071). These cash flows are expected to recover the overall capital outlay of PHP 48.14 million (USD 859,642). A net present value (NPV) of PHP 3.164 million (USD 56,500) and a 5.77-year payback period (PBP) were calculated through cost-benefit analysis. The environmental analysis revealed positive impacts on reducing the volume of wastes, water resources, and quality, odor and air quality, and soil and nutrients. Considering these, the study provided recommendations on project implementation to achieve sustainable waste management and circular economy in the municipality.

Mechanism and spatial spillover effect of digital economy on common prosperity in the Yellow River Basin of China

The digital economy has emerged as a new trend in economic development and has profoundly influenced the process of achieving common prosperity. However, current research on the correlation between the digital economy and common prosperity from the perspective of a river basin still needs to be strengthened. Based on this, the present study first theoretically elaborates the conceptual meanings of “digital economy” and “common prosperity”, as well as the mechanism by which the digital economy empowers common prosperity. Subsequently, a scientifically-constructed performance evaluation index system for the digital economy and common prosperity is established. Considering the Yellow River Basin as an empirical case study area, this study investigates the mechanism and spatial spillover effects of the digital economy in empowering common prosperity from 2005 to 2020. The research findings reveal that: (1) The Yellow River Basin exhibits a basin characteristic with downstream > midstream > upstream areas regarding the level of common prosperity and digital economy. It indicates that a distinct spatial correlation exists between the two factors. However, the ongoing decrease in both high-level and very high-level areas reflects the lengthy and challenging journey of enhancing the quality and efficiency of the digital economy in empowering common prosperity. (2) The digital economy not only directly impacts common prosperity, but also fosters its development through spatial spillover effects. Among the control factors, informatization and housing levels have a major stimulating effect. (3) There exists a clear regional heterogeneity in how the digital economy affects common prosperity in the Yellow River Basin. Specifically, common prosperity of downstream cities is significantly impacted by the digital economy. The spatial spillover effects of the digital economy on common prosperity exhibit a pronounced “neighborhood as a moat” characteristic. (4) The digital economy facilitates the achievement of shared prosperity through the implementation of mechanisms centered on sharing, affluence, and sustainability. These research findings illuminate the empowering mechanisms and spatial spillover pathways of the digital economy in promoting shared prosperity, aligning with national strategies for ecological conservation and high-quality development in the Yellow River Basin.

Pracownik samorządowy a prowadzenie działalności gospodarczej

The economic system of the Republic of Poland is based on a social market economy, one of the pillars of which is freedom of economic activity. Therefore, everyone is allowed to start, run and terminate a business activity. A special category of employees are local government employees who are expected to be professional, reliable, conscientious and diligent in their work. It is also an obligation to act impartially and take care of the public interest first. Local government employees are obliged to refrain from activities that may expose them to accusations of self-interested and biased behavior and must report their additional activities to their superiors. Performed outside of employment in offices and local government units additional employment or running a business may expose a local government employee to accusations that his/her activities are not guided by the public interest and the legitimate interests of citizens. For this reason, local government employees experience a number of restrictions in conducting various types of activities, also commercial ones, including business activities, outside of work in offices or other local government units.

Optimization of Enterprise Financial Risk Management and Crisis Early Warning System Supported by AI

The stability of the financial market plays a key role in the overall health of the economic system, and optimizing corporate financial risk management and crisis warning systems is of great significance. Traditional financial risk management methods often face challenges when processing large-scale, resulting in a decrease in the accuracy of risk assessment.

Leverage diverse data sets to improve the accuracy of financial risk assessments and the effectiveness of crisis warnings. Experimental results show that the algorithm outperforms the baseline model in terms of risk prediction accuracy, efficiency and stability. For example, on the LendingClub loan dataset, FLOPs are reduced by more than 46.8%, inference time is improved by more than 48.5%. This method provides new perspectives and solutions for optimizing corporate financial risk management and crisis warning systems. This will have a positive impact on the stable operation of enterprises and other aspects.

An analytical solution to ground stresses induced by tunneling considering ground surface boundary conditions and gravity

Accurately predicting the stress distribution around the tunnel is crucial for designing safe and economical support systems. The stress distribution is closely related to the ground stress release induced by tunneling, as well as the initial gravity stress and boundary conditions. In this study, a two-dimensional analytical model considering the ground surface boundary conditions and gravity is presented to investigate the stress field around the tunnel. Then, a numerical model was developed to validate the proposed analytical model. Finally, parametric analyses were conducted, and the limitations of the load calculation method of the code for design of shield tunnel in China were discussed. The results indicate that: (a) Tunnel excavation induces stress redistribution in the soil, resulting in a soil arching effect around the tunnel. This arching effect causes nonlinear load changes around the tunnel. (b) The soil mass around the tunnel can be divided into undisturbed and disturbed zones. Above the tunnel, the disturbance range is C-2D(C and D represent the burial depth and the tunnel diameter), while below and on both sides of the tunnel, the disturbance ranges are 4D and 1.5D, respectively. (c) Once the stress release rate reaches 0.6, a combined arching effect zone, consisting of both major and minor principal stresses, is formed in the disturbance zone above and below the tunnel. (d) The load distribution pattern calculated by the code for design of shield tunnel in China is gourd-shaped, and this calculation method is insufficient for accurately evaluating the load around the tunnel. The research results can provide a reference for the design of the shield tunnel.

Socio-monetary and Demographic Profile of Gujjar and Bakkarwals of Poonch District

The present study is an attempt to understand the educational backwardness of scheduled tribes of district Poonch of Jammu and Kashmir. The Scheduled Tribes (ST’s) are the socially and educationally deprived people in India. Scheduled Tribes have specific histories of social and monetary deprivation and the underlying reasons in their educational marginalization are also strikingly awesome. Schooling forms a crucial factor inside the average improvement of people, enabling them to get extra awareness, higher comprehension in their social, political and cultural surroundings and additionally facilitating inside the development of their socio-monetary conditions. The time period “tribe” was earlier used for a network which constituted a homogenous institution that lived in overall isolation having a particularly self-sustaining economic system independent political setup and which maintained wonderful customs, religions practices inherited from one common place ancestor. The scheduled tribes are the oldest settlers, if no longer the primary in India and India has the second one biggest concentration of the tribes inside internationally. Scheduled tribe population constitutes 8.6% of the entire population in India. Jammu and Kashmir has many tribal communities having their own traditions, cultures and customs. Scheduled Tribe groups have traditionally lived in remote and some difficult terrains in the direction of forests and natural assets. Most of the tribes live in inaccessible areas.

Tradeoffs between economy wide future net zero and net negative economy systems: The case of Chile

Given the possible economic consequences, poorer countries have more challenges in delivering their Nationally Determined Contributions. As a developing country, Chile has pledged to attain carbon neutrality by 2050. While Chile has implemented several mitigation measures, it still relies heavily on carbon sequestration, intending to sequester around 65 MtCO2e by 2050. However, heavy reliance on sequestration poses several risks as the literature shows that natural sinks, particularly forest and land, are exposed to severe impacts from global warming and climate change. Fortunately, Chile has significant renewable energy potential, which, if fully utilized, may move the country towards a net negative emissions context. To assess if such a net-negative system is feasible in the context of Chile, a new regional version of the Global Change Analysis Model for Chile is developed. The model is used to investigate the effects and required levels of investment in renewable energy and decarbonization of end-use sectors to achieve economy-wide net negative emissions scenarios. The design of net negative pathways follows a statistical approach based on the expected sequestration capacity in 2050 and its corresponding confidence interval. The results are compared to scenarios that are aligned with the objective of carbon neutrality by 2050. The findings show that obtaining net-zero emissions by 2050 is possible, however achieving net negative systems will be dependent on existing sequestration capacity and the application of economic incentives to boost green energy deployment in Chile as well as to push such green energy, in the form of electricity or e-fuels, into hard to decarbonize final demand sectors, such as transport, mining, and industry demand sectors. The results also indicate that after significantly reducing CO2 emissions from the energy sector (primarily the power sector), the agricultural sector and other urban and industrial sectors still contribute to non-significant levels of CH4 and N2O emissions.

A Bayesian regularization radial basis neural network novel procedure for the fractional economic and environmental system

The motive of current work is to design a novel radial basis Bayesian regularization neural network (RB-BRNN) for solving the nonlinear fractional economic and environmental system (FEES). A radial basis activation function in the hidden layers is applied by taking 20 numbers of neurons. The mathematical FEES is presented in three classes, named as cost of control accomplishment, manufacturing elements competence and technical exclusion’s diagnostics cost. A reference dataset is obtained using the Adams numerical results to reduce the mean square error (MSE) by taking the data for training 70%, while 15% is used for both testing and validation. The negligible absolute error values and comparison of the solutions develop the worth of computing RB-BRNN in order to solve the nonlinear dynamics of the FEES. Error diagrams, regression values, and the MSE performances are implemented to assess the precision of the designed solver.

COMPARATIVE LEGAL ANALYSIS OF TAX MEASURES TAKEN IN CRISIS CONDITIONS

The world's economic and legal systems are facing a huge challenge to overcome the negative consequences imposed by recent social distortions. In 2020, what started as a health crisis quickly turned into an economic-social problem where an express response was required to ensure the functioning of social actors. This economic-social crisis was followed in a short period by new security crises with additional consequences on national systems. The response to the newly created conditions requires a multidisciplinary approach that will include measures of a health, economic, social, and security nature, adopted on the principles of legislation and expediency within the national legal systems. These measures have their own direct or indirect tax component. The purpose of this paper is to perform a legal analysis of the tax measures taken in the national systems. The scope of the research covers the member states and candidate countries for membership in the European Union. The focus is on the more recent crisis period, with particular emphasis on the COVID-19 period. The analysis primarily focuses on the legal element of the tax measures, the procedure of their implementation, and their legal nature. Also analyzed are the challenges that they have on the taxpayers and the administrative authority for their performance. The method of comparison in the paper is used to compare the similarities and differences between the tax measures in the different national systems and to detect the legal challenges imposed by the established crisis conditions. At the end, conclusions are given about the current situation and recommendations on how the establishment of tax systems should be in the future in crisis conditions.
