This paper aims to analyse the impact of the hybrid cloud-based learning environment providing resources and services to implement interdisciplinary projects in the course of studies on the efficiency of education. A combination of modern methods of pedagogical studies was applied to address the set problems. The authors used theoretical methods, such as analysis, generalisation, comparison, synthesis, and systematisation of research literature and teaching aids providing visibility in terms of the current outlook of the analysed problem and developing and introducing a hybrid cloud-based learning environment to support interdisciplinary projects. The authors also used empirical methods, such as pedagogical experiments, to determine the impact of digital services in the hybrid cloud-based learning environment on students' performance in each discipline of interdisciplinary projects and their profiles in the course of the project. For numeric processing of research findings and statistical tests for objectivity, the authors used methods of mathematical statistics. The case is made for using cloud computing in the education of future professionals. Experimental analysis is conducted to determine the impact of the hybrid cloud-based learning environment providing resources and services to implement interdisciplinary projects in the course of studies on the efficiency of education. The positive impact is shown for the hybrid cloud-based learning in terms of students' progress. The results can make the basis for developing and introducing a hybrid cloud-based learning environment to support interdisciplinary projects. The scientific novelty of this study is underscored by the analysis of the impact of digital services of the hybrid cloud-based learning environment on the efficiency of educating future professionals in the course of an interdisciplinary project.

The objective of the article is to examine the process of digitalization of the EU cultural diplomacy enhanced by the pandemic of COVID-19, considering the factors of the long-term cycles called long waves. The theory of long waves is represented by various concepts, the first one was the Kondratiev model. On their basis, indicators of the onset of a new wave were identified: 1) Innovation implementation; 2) Economic challenges; 3) Social transformation; 4) Sustainability. From the point of defining the correct terminology, the terms ‘digitalization’ and ‘digitization’ are presented. The statistics data presents the current implications of the COVID-19 pandemic for the cultural sectors and influencing the acceleration of digitalization, which indicates the relevance of this study. The final part offers the main features of the development of the EU cultural diplomacy, considering the mentioned indicators of a long new wave. Future research could be based on the discovered consequences of accelerating digitalization of cultural diplomacy.

The objective of the article was to reveal the international imbalances caused by the COVID-19 pandemic through the coordinates of chaos theory. Methodologically it is a critical essay based on documentary observation. To understand the current state of world politics and the balance of power in international relations, it is appropriate to use chaos theory. At the beginning of the article, the origins of chaos theory are an interdisciplinary study, and its basic concepts are introduced. The value of using chaos theory and its great potential for analysis and applications in the study of international relations is shown in the example of the 2019-2020 events in Wuhan is the capital of Hubei Province in the People's Republic of China (PRC). associated with the onset of a COVID-19 viral infection that has spread around the world. At the end of the article, conclusions are drawn and the strengths and weaknesses of the use of chaos theory in dialectical relation to international relations are revealed, both as a field of study and at the same time as geopolitical reality.

The COVID-19 pandemic and the coronacrisis have clearly exposed the strong dependence of modern companies on data governance, the stability of information networks and digitalisation and significantly strengthened the Europeans' belief in the need to achieve strategic autonomy in the development of their own digital solutions. The article aims to define the place of the European Union in the international information and communication space in the context of global data governance policy. The methodology is based on the principles of the multi-paradigm method used for extrapolating some provisions of Robert Gilpin’s hegemonic stability theory on the modern technological competition among the countries on the international arena through a regional approach. The article considers the term “information sovereignty” based on the principles of international law within a constantly changing international environment. The research addresses such documents as “A New Industrial Strategy for Europe”, “A European Strategy for Data”, and the decision of the European Court of Justice concerning the transatlantic Privacy Shield agreement. As an example of the European digital policy, it examines the ambitious GAIA-X project designed to create an open digital ecosystem and common requirements for a European data infrastructure. The article formulates the recommendations in order to ensure effective governance in the digital sector and proposes a multi-stakeholder model, which would help achieve information sovereignty based on European values and ideals.
