  Energy integration in the European union as an instrument for accelerating the green transition

It assesses how the deepening of the internal energy market, cross-border infrastructure and coordinated regulation facilitate the integration of renewable energy into the EU energy system. The analysis combines academic literature, EU strategic and regulatory documents, and Eurostat and European Union Agency for the Cooperation of Energy Regulators (ACER) data for 2004�2024. The findings show that progress is strongest in the electricity sector, while grid congestion and insufficient cross-border capacity still limit the overall effect of integration.

  The interplay between trade integration and air transport in Africa

The objective is to systematize and synthesize existing literature and to develop an integrated conceptual framework for analyzing their combined economic ... This study examines the interaction between the African Continental Free Trade Area (AfCFTA) and the Single African Air Transport Market (SAATM) in the context of economic integration in Africa. The objective is to systematize and synthesize existing literature and to develop an integrated conceptual framework for analyzing their combined economic effects. The study adopts a qualitative approach based on a conceptual literature review. The results indicate that trade integration and air transport liberalization are interdependent processes, operating through key mediating factors such as transport infrastructure, institutional coordination, regulatory harmonization, and the reduction of non-tariff barriers. The findings suggest that the interaction between AfCFTA and SAATM can generate cumulative economic effects, although their realization depends on structural and institutional conditions. The study contributes to the literature by integrating two largely separate analytical fields and by proposing a conceptual framework for future empirical research.

This empirical survey study aims to define the motivational profile for educational migration among high school graduates in the city of Varna. First, a descriptive frequency analysis will be used to identify those who wish to continue their education in Bulgaria. Next, a comparative analysis will examine whether those leaving speak more languages than the remaining respondents. The third part of the empirical study will rank the motives by importance for respondents leaving their homeland and analyze the correlations between them. The analyses were performed using SPSS Statistics. The key findings indicate that internal factors have a stronger influence, and the primary motivations for educational migration among the respondents are the desire for personal development, followed by the pursuit of a better education.
