In Poland, the development of photovoltaic (PV) installations is an important element in the development of the Renewable Energy Sources (RES) sector and supports the prosumer power industry. The purpose of the article is to present a case study of the PROSUMENT program. It analyzes the data available to date on the development of the PV market in Poland. Apart from the costs of installing the PV systems, the article analyzes the profitability of investment for different micro-power installation capacities. A calculation for micro-power installations subsidized under the PROSUMENT program for various PV capacities is presented, along with the actual amount of the subsidy. The adopted calculation methodology is a comparative verification analysis of the investment cost estimate for a for the two studied PV facilities, i.e., Micro-power installation 1 and Micro-power installation 2. The building’s annual energy demand was adopted at the same level for both examples, with fixed active energy and distribution fees. The study includes a cost estimate for installing the PV systems and the profitability of the investments for various micro-power installation capacities. The analysis of the subsidy under the PROSUMENT program demonstrated that, in the analyzed period of 2016–2020, the best results were achieved by investments with a capacity of 10 kWp. In terms of the net subsidy value, the best results ranged between 27.20 and 19.10% of the total investment costs. Development of the Polish prosumer power market requires building public awareness of prosumer power production as an opportunity for the growth of the Polish economy.

Entrepreneurs, opportunities, and entrepreneurial behaviors play an important role within the theory of entrepreneurship. However, we have limited knowledge about possible associations among these factors. Therefore, this study investigates these interactions. The study aims to identify the combinations of entrepreneurship dimensions, entrepreneur motivation, and opportunity perception that lead to an increase in a firm's performance. This study focuses on the small and medium-sized enterprise (SME) sector, wherein the entrepreneurial spirit is dominant. It is based on a sample of 61 SMEs operating in the Lesser Poland region of Poland. The factor's combinations are identified with a fuzzy-set qualitative comparative analysis (fsQCA). The analysis reveals previously unknown combinations of the investigated factors leading to performance in SMEs, with varying roles depending on accompanying factors. Specifically, this study reveals the following combinations that lead to a firm's performance: opportunity openness with proactiveness, heterogeneity of motivation with innovativeness, and risk-taking with proactiveness. These observations highlight the role of combining various conditions to improve performance. This study's findings contribute to the entrepreneurship and SME literature by explaining the role of different combinations of factors in determining a firm's performance (including the motivations and opportunity perception of the entrepreneur). It also provides meaningful implications for entrepreneurs and managers, indicating combinations of factors that lead to an increase in firm performance, the role of the diversification of opportunities, and the importance of motivation differentiation.

The main objective of the paper is to present the development of digital economy and society in the Countries of the European Union in the light of the digital convergence of these markets. The analysis was based on the data on the Digital Economy and Society Index (DESI) from 2015 and 2020. Empirical studies have been conducted in two stages. First, basic measures of time series dynamics were used to determine the dynamics of changes in index values. On the other hand, in order to classify countries in terms of similarity of value and structure of the DESI, a cluster analysis was used as one of the basic methods of the so-called unsupervised statistical grouping. The studies presented confirm that the levels of indicators and the dynamics of changes in their value at the level of the synthetic DESI indicator, and in the five underlying areas of analysis, vary despite the fact that almost all are pro-growth, including for isolated clusters of EU-28 countries. When analyzing the DESI synthetic index and its components, it was concluded that there is generally an increase in convergence between the EU-28 countries in terms of the level of development of the digital economy and society, as well as in four components: Connectivity, Human Capital, Use of Internet Services and Digital Public Services. The Integration of Digital Technology area was the only one where increasing polarization of results was observed. The added value of the paper is to fill the research gap in research on the digital convergence of markets in the Countries of the European Union.

Amidst the changes and adjustments of the international energy situation, the leading trend is to shift from fossil fuels to low-carbon fuels, and ultimately, to enter the era of sustainable energy, based mainly on renewable energy. The ongoing changes in global security of energy supply and the high volatility of fossil energy prices also stimulate investment in alternative energy sources, making renewable energy sources (RES) one of the rapidly growing elements in the global energy system. This article fills the research gap by analyzing the potential of using renewable energy in the countries of the Commonwealth of Independent States (CIS) in the years 2015–2018. The authors address the energy potential in the years 2015–2019, and energy consumption in the years 2015–2018 as the potential of RES in the CIS countries was not researched after 2014. Please note that the study covers the CIS countries, along with Georgia and Ukraine, which are no longer formal members of the Community, but have been included for cognitive and comparative purposes. Upon comparing the increase in energy production in the CIS countries to the average increase for the European Union (EU) countries, the value of this increase is observably higher than the average for the EU countries only in Ukraine. However, the average for the entire CIS is much lower than the EU average, therefore in CIS countries, the changes in the volume of RES energy production are varied. In some countries, there is a significant increase in the production of this type of energy (e.g., Ukraine, Kyrgyzstan, Belarus, Kazakhstan, Georgia). However, there are also countries in which the changes are negligible, or which noted significant drops in RES energy production (Uzbekistan, Moldova, Russia, Armenia). The findings contribute to the RES market debate and the international relations theory by comparing political factors with territorial and economic factors.

Background: A review of epidemiological data demonstrates relationships between defined health behaviours linked with religious affiliation and a reduced risk of developing and dying from Cardiovascular Disease (CVD). The aim of the study was to compare the lifestyle of Seventh-day Adventists (SDA) and Catholics (CA), to determine the relationship between the lifestyle of SDA, CA and the level of serum homocysteine as a risk factor for CVD. Methods: A cross-sectional study was conducted on 252 SDA and CA. The following tools were used: interview questionnaire, anthropometric measurement, the International Physical Activity Questionnaire (IPAQ), the Inventory of Health Behaviours (IHB), the Perceived Stress Scale (PSS-10), laboratory tests (homocysteine level), and the Fagerström Test for Nicotine Dependence (FTND). Results: Selected lifestyle elements, such as smoking cigarettes, drinking alcohol, physical activity, diet, Body Mass Index (BMI), health behaviours on the IHB, psychosocial factors and level of stress for CA were significantly different in comparison to SDA. The religion professed by the respondents was not significantly associated with the increased level of homocysteine as a risk factor for cardiovascular diseases (CVD). The level of homocysteine for CA were significantly different in comparison to SDA. The studied group of CA was significantly influenced by socio-demographic factors: gender, age, education, place of residence, BMI and lifestyle: drinking alcohol and smoking cigarettes, consumption of dark bread, pasta, and groats. For the studied group of SDA, the level of homocysteine was significantly influenced by socio-demographic factors such as gender, age, professional activity, and consumption of legumes. Conclusions: Public health professionals and nurses should develop culturally specific educational interventions.

In the renewable energy source (RES) market, which is highly atomized, business events play an important role in supporting inter-organizational cooperation. The aim of this paper was to examine the impact of three characteristics of the events, namely, the location of the event, type of event (brokerage event versus company mission), and type of leading partner (public versus private), on the effectiveness of the business events (expressed by the number of meetings during an event and the number of partnerships initiated as a result of these meetings). We analyzed 304 promotional events organized in the European RES market. We employed basic statistical tests to verify our hypotheses. Our findings suggest that (1) the numbers of meetings and partnerships differ depending on the event’s location (country and region of Europe), (2) the type of the event (brokerage event versus company mission) affects the numbers of meetings and partnerships (in particular, during brokerage events (BEs), significantly more meetings take place than during company meetings (CMs)), and (3) the type of an event’s leading partner (public versus private) has no impact on the numbers of meetings and partnerships. With its findings, this paper contributes to RES market development and the theory of inter-organizational relations. It presents meaningful implications and recommendations for enterprises, business networks, and event managers operating in RES markets.

The main goal of public intervention is to amend market imperfections. However, public agencies may also have other goals in supporting entrepreneurship and promotion of self-employment. The aim of the paper is to analyze the impact of the funding granted by the Małopolska Agency for Regional Development (Małopolska Agencja Rozwoju Regionalnego SA, MARR S.A.) dedicated to beneficiaries from the Tarnow subregion and the Krakow Metropolitan Area. The research goals were defined as follows: (1) To verify if the basic assumptions of the program are correct and to demonstrate that it is an important element motivating the professionally inactive to take up employment as sole entrepreneur. (2) To verify if the program participant structure (both applicants and beneficiaries), with subdivision into place of residence, gender, age and the labor market status, is correct. (3) To verify if the abovementioned variables (gender, age, place of residence) significantly differentiate the applicants’ chance of obtaining a grant. The results are of key importance and should be used in formulating assumptions, regulations and guidelines for subsequent program editions. Due to the demonstrated diversity of the target group in the respective regions, it should be decided whether to differentiate the criteria for participation in the project depending on the region.

Stable and sustainable economic development—including that of renewable energy resources (RES)—requires institutional support of an environment that would enable market operations, and support them in case they are ineffective. Innovation brokers, including structured technology transfer networks, play a key role in promoting, disseminating, and liaising between the parties in the RES sector. The aim of the paper is to present the structure of events used to promote RES in Europe by the Enterprise Europe Network in the years 2017–2018; to verify whether the type of promotion instrument used is significantly related to the location of the events organized; to research whether the selection of the supporting partner is determined by the organized event’s geographical location. The analysis is carried out by means of an empirical study of the network of innovation brokers, i.e., the Enterprise Europe Network. Additionally, the available data are analyzed in terms of the type of the partner supporting individual events. It has been shown that there is a significant variation in the structure of the types of events for individual regions of Europe. This could mean that the organizers’ decisions as to the type of events organized in particular regions of Europe are deliberate and in some way adjusted to the region in which they take place.

Jednym z elementów procesu zarządzania siecią bankomatową jest dogłębna analiza struktury wypłat z poszczególnych bankomatów oraz z określonych grup bankomatów o zbliżonej lokalizacji. Jest to element niezbędny przy podejmowaniu decyzji o wyborze lokalizacji dla nowych bankomatów oraz o likwidacji określonego bankomatu lub bankomatów z jakiegoś typu lokalizacji. Ważnymi elementami struktury wypłat, zwłaszcza w ujęciu opłacalności funkcjonowania bankomatu, są liczba oraz wielkość wypłat z bankomatu. Liczba wypłat z bankomatu jest związana bezpośrednio z przychodami operatora z tytułu opłaty interchange oraz reklam wyświetlanych podczas korzystania z bankomatu przez klienta. Im większa liczba operacji wypłat, tym większe przychody dla operatora sieci. Z kolei wielkość wypłat powiązana jest bezpośrednio z kosztami, jakie ponosi operator. Większe wypłaty z danego bankomatu oznaczają wyższe koszty związane z przygotowaniem i dostarczeniem gotówki do bankomatu oraz jej „zamrożeniem” w bankomacie. Celem przeprowadzonych badań jest wskazanie tych typów lokalizacji bankomatów, które potencjalnie przynoszą największe zyski, tzn. występuje w nich najwięcej wypłat o stosunkowo niskiej wartości. Dodatkowo zweryfikowano, czy występuje istotne zróżnicowanie w liczbie wypłat oraz w wielkości wypłat pomiędzy grupami bankomatów z różnych typów lokalizacji. W analizie wykorzystano szeregi czasowe liczby i wielkości wypłat z bankomatów jednego z największych operatorów sieci bankomatowych w Polsce. Dane dotyczą bankomatów zlokalizowanych w województwach małopolskim i podkarpackim. W celu porównania struktury wypłat oraz wykazania ich zróżnicowania w poszczególnych bankomatach i grupach bankomatów wykorzystano podstawowe miary statystyczne oraz wybrane testy statystyczne. W wyniku przeprowadzonych badań zostały wyodrębnione te typy lokalizacji, w których instalowanie bankomatów z dużym prawdopodobieństwem przyniesie większy dochód. Przeprowadzone analizy mogą posłużyć operatorom bankomatowym przy wyborze typu lokalizacji.
