This work contains a description of a technique for constructing two synthetic indicators (measures) using a graphical presentation in the form of radar maps. The paper presents the structure and properties of indicators and their formal notation specially created for this purpose using the analogon of a scalar product of vectors. In particular, it proves the theorem on polygon fields, induced by radar maps, prepared for structural vectors, which allows to build concentration indicators. In order to demonstrate the usefulness of tools constructed by such means, the example shows how significant structural changes can be imperceptible when utilizing only the GINI concentration indicator’s value, but are noticeable when using the concentration indicator developed by the authors. In addition, it illustrates the change in the value of concentration indicators (GINI and the indicator developed by the authors) on two families of Lorenz curves, together with changes in concentration. The practical application of this technique for constructing indicators that create rankings is presented on empirical data on the level of material deprivation in the countries that joined the EU in 2004 and 2007. These data have also been annotated (for comparison purposes) using the so-called overrepresentation maps (Grade Correspondence Analysis method).

Technological development of society is of unequal cyclic nature and is characterized by changing periods of economic growth, stagnation phases, and technological crises. The new wave of technological changes and new technological basis corresponding to the technological paradigm boost the role of innovations and displace the traditional factors of economic growth. Currently, intellectual and scientific-technical capacity are the main economic development resources. The use of innovation and new knowledge change the technological structure of the economy, increase the elements of the innovative economy, knowledge economy, and digital economy, i.e. the new technological paradigm is formed. The paper aims to research the basic determinants of technological paradigms’ forming and development, and determining their key features, as well as to analyze social transformations of the EU Member States and Ukraine. The paper focuses attention on the research of the features of social transformations. The structural transformations are analyzed based on the Bertelsmann Transformation Index that estimates the quality of democracy, market economy, and political governance. The transformation processes are assessed on the example of the EU Member States and Ukraine. The authors argue that social transformations and structural changes in the economy are related to the change of technological paradigms that boost the economic modernization and gradual progressive development of humanity in general. The nature and main determinants of 5 industrial and 2 post-industrial technological paradigms are outlined. Their general features and main areas of basic technologies implementation emerging in the realization of a certain technological paradigm are explained. The conclusions regarding the fact that innovative technologies and available scientific-technological resources define the main vector of economic development are made. The new emerging technological paradigm is of strategic importance for society development.

The pandemic crisis and the linked infodemic are extraordinary cases to test the EU capability to manage the disinformation disorder, especially towards young people. This paper aims to analyse the impact of the EU communicative actions regarding disinformation about Covid-19, on trust and sense of belonging in young Italian and Spanish university students. The research presents an exploratory and quantitative study that uses a second-generation multivariate analysis method. The results show that trust can be very well the resource on which EU communicative actions may positively impact. Nevertheless, our study reveals that the EU in-stitutions measures have not increased sense of belonging in EU integration.

Economic activities are featured with certain cycles. The cycles can concern the whole economy as well as particular sectors. The dairy industry is one of the branches that are of high importance in Polish and the world as regards food sector. Polish dairy industry faced deep structural changes and modernisation. After the accession to the EU domestic market is strongly linked to both the EU and the world markets. The production in Poland exceeds consumption by ca 20%. The surplus is exported, which ties up the situation on the domestic market with the situation on international markets. Conducted analysis of the domestic and the world markets of milk skimmed powder showed parallel fluctuations. Domestic prices and the prices on the world markets are strongly correlated. The knowledge on the characteristics of those fluctuations allows stakeholders for a proper risk management as well as elaboration of suitable policy options by government administration.

The decline of Oman’s fish exports to the European Union (EU) since mid-2000s has caused legitimate concerns among policy makers and exporters. However, the potential reasons for the decline have not been fully elucidated. To ascertain the underlying causes of such decline, this article empirically examines the relative significance of potential economic and policy-related factors such as border rejections influenced by health and safety measures, supply and demand capacities, domestic ban, domestic structural changes, and exchange rate fluctuations on Oman’s fish exports to the EU. The results obtained from the dynamic unbalanced panel data model for the period 2000-2013 indicate that fish exports to the EU markets have been influenced by the domestic ban on export, domestic structural changes, and exchange rate fluctuations rather than by border rejections. These findings provide important signal to policy makers of the respective countries in designing adaptive policy approach to address such influences.

Abstract This paper presents the questionnaire results of the research on implications of the effects of Slovenia’s accession to the European Union (EU) on structural changes in agricultural holdings (AHs) in the case of Škofjeloška hilly-mountain rural areas. The effects are studied based on the analysis of income diversification of AHs three years before the Slovenian accession to the EU in 2000 and six years after the Slovenian accession to the EU in 2010. Strategies of AHs on the basis of the questionnaire were analysed in early 2011. Income diversification of AHs with non-agricultural employment and off-farm incomes is necessary for survival for the majority of AHs. There are observed differences in structural changes in the AHs between areas with different natural conditions for agricultural production, and particularly in the extent and in the direction of structural changes by socioeconomic types of AHs. Structural changes inhibit non-economic objectives of AHs, while non-agricultural employment has a two-way influence.
