The aim of this article was to show the impact of the principle of equal opportunities for women and men on the perception of the role of women in management. Investigating the impact on the development of a gender equality situation shaped the scope of the subject matter of the qualitative and quantitative analysis carried out from the perspective of equalization of opportunities for women and men in the management environment. Another aim of the article was to ascertain whether there occurs a dynamic equalization of barriers between men and women over time. The analysis of the material collected allowed for some conclusions and their interpretation gave rise to some assumptions about the future development of the phenomenon. As a result, it was concluded that social and legal education of women is a key demand, and that all actions stemming from the principle of equal opportunities for women and men, combined with social sensitivity in the broadest sense, can contribute to minimizing inequality in the future.

The main aim of the article is to compare the implementation of the green city concept in capital cities above 1 million population in Central Europe, i.e. Warsaw, Prague and Budapest in order to evaluate the degree to which each of these cities implement the assumptions of the abovementioned concept to achieve urban sustainability. An analysis of strategic documents on urban planning as well as data bases of the three cities was carried out. The results allowed for measuring the progress and effectiveness of the environmental policies of these cities and determining their achievements and shortcomings when it comes to realizing the green city model. Additionally, for the purpose of this research, an attempt at elaborating the definition of a ‘green city,’through determining four phases of its development, was made. Thus, the article is solution-specific, in that it points at possibilities of the development of Central European cities as regards the implementation of the green city concept.

The article presents an analysis of the relation between the scale of Polish government investments into renewable energy sources and the price of EUA Futures contracts and funds obtained by Poland from their sale in the years 2013–2020. The goal of the analysis was to check if there is any relationship between the funds obtained from the sale of EUA contracts and Polish government investments in renewable sources of energy. The theoretical section contains a partial research of sources, whereas the analytical part uses the comparative, descriptive and graphic methods, as well as Pearson correlation coefficient. The results of the study indicate a lack of relationship between the EUA prices and Polish government investments in renewable energy sources in 2013-2020. The study shows that, at that time, about 75% of investments expenditure for renewable energy sources in Poland came from private institutions and business entities and only 7% of the financial outlays came from state-owned energy companies.

The demographic and managerial circumstances allow one to expect that Polish organisations, both business and nonprofit, will be facing organisational succession in the near future. The independent Polish state will be witnessing these processes for the first time since over 200 years. The presented paper addresses a research gap referring to succession in Polish nonprofit organisations. The design of the study was based on the theory and experience gained from family business literature and research. The aim of the study was to describe and analyse formal succession solutions included in the statutes of Polish foundations and to put the results into perspective, building on a theoretical family business background. The study was based on a qualitative analysis of documents from ten purposefully selected foundations operating in Poland. The study indicates that the documents of the analyzed foundations contained no formal solutions regarding succession. Other records referring to power transfer concerned emergency situations. The findings were correlated with the demographic and managerial circumstances facing the foundations. Possible directions for future research were indicated.
