The article is devoted to the theoretical substantiation and development of methodological approaches and practical recommendations for modeling the assessment of the financial stability of a service sector enterprise. To assess the financial condition of the hotel industry, a visual interpretation of the neural network, a model of self-organizing Kohonen map, was used. It is proven that by the method of Kohonen maps for each service provided by the hotel industry, in a certain period of activity, it is possible to establish certain objective limitations of structural characteristics that will prevent the transition to problem clusters or ensure the transition to better ones. The authors propose an economic and mathematical model of the process of assessing financial stability by calculating the integral indicator of financial stability of the service sector. The types of control maps for each of the coefficients that have a significant impact on the assessment of the financial stability of the enterprise in the service sector were identified. Control maps were constructed for each coefficient, which are part of the integrated indicator of financial stability, and their analysis was carried out for the presence of special reasons for the variability of the process of financial stability assessment. The concept of modeling a system for assessing the financial stability of service enterprises is developed in the article, which is based on the collection of financial data, a comprehensive analysis of factors influencing the financial condition, a study of the controllability of the process of assessing financial stability, building a model of an integral indicator of financial stability, and its program implementation.

A demonstration of the relationship between the share of renewables in gross marginal energy and selected countries’ economic growth is the basis of this research. The paper seeks to investigate mutual correlations between renewable energy sources and economic growth for two EU economies and how it influences their fluctuations (increase and decrease). The comparative analysis of results was carried out for less-income Polish and high-income Swedish economies. This research used a regression model to answer the research questions examining the presence of correlations between renewable energy sources in gross marginal energy consumption and economic growth. This study analyzes data starting from 1991 to 2022. The results indicated a positive correlation (statistical significance) between Gross Domestic Product and Gross National Income variables for Sweden (84.6% and 83.7%, respectively) and Poland (79.9% and 79.2%, respectively), which influence the use of renewable energy sources. The findings also reveal that the higher economic growth caused by the use of renewables is observed for the leading countries but at the same time the risk of a greater recession is much more likely than in other countries. These findings would help government officials and policymakers to better understand the role of renewable energy in the economic growth of these countries. This study has contributed to the literature on renewable energy sources and statistical reports under the EU energy sector framework.

According to the United Nations, 1.3 billion tonnes of food, one third of which would be edible, is being wasted worldwide. In Europe alone, around 89 million tonnes of food are being wasted. 178 kg of food is thrown out per inhabitant of the European Union every year. In Poland annually, according to reports of the Federation of Polish Food Banks, they waste about 235 kg of food per capita, which places Poland in 5th place in relation to food throwing away in Europe. Throughout the country, Poles waste 9 million tons of food. Food wastage is not only referred to as a phenomenal aspect, but also as an economic, social and energy aspect, as well as influencing the environmental aspect. At every stage of the food chain there is a responsibility for food waste, which is why it is necessary to take action to limit these losses.

The concept of a creative class was introduced by Richard Florida in 2002 in his book The Rise of the Creative Class. The creative class consists of people involved in occupations recognised as inventive. This study is designed to identify capacities for the development of creative capital in the counties of Lithuania. Florida’s methodology for his creative model refers to the three powers of talent, technology and tolerance, which are determinants of development. The present assessment is based on generally available data acquired from the Statistical Yearbook of Lithuania. It takes into account information related to all the counties of the Republic of Lithuania. The accumulated data described are, at a relative level, the areas of talent, tolerance, technology and cultural amenities.
