Participation in International Integration Associations as a Factor of Ukraine’s Global Competitive Power

Current glocalisation processes require the identification of priority areas for Ukraine’s further integration into the international economy. The right choice of direction, tools and forms of implementation allows the government to determine, justify and implement a competitive strategy for the country. The study aimed to determine the relationship between international economic integration and Ukraine’s global competitive power. Identifying Ukraine’s sectoral comparative advantages in trade with the EU and evaluating the index of the regional orientation of Ukraine for specific groups of goods and services made it possible to define the effects of economic collaboration with the European region. The assessment of the complementarity index of Ukrainian–European trade relations revealed that Ukraine and the European Union are main trading partners. Furthermore, the analysis of the mechanism of the Association Agreement between Ukraine and the European Union proved that the agreement actively contributes to the growth of Ukraine’s global competitive power. Comparative analysis in historical retrospect revealed priority areas for  improving the integration processes which help to form the main competitive advantages of the country.

Social Partnership on Wage Regulation in Ukraine’s Public Sector

In the face of constant pandemic-related and military threats to citizens’ right to work, collective bargaining has become almost the only real instrument to reconcile the interests of social partners and consolidate their efforts. The authors proposed a methodology for assessing the development of social partnership in the regulation of labour remuneration based on a set of indicators and a comparative analysis of the indicators in several public organisations: the State Audit Service of Ukraine, the State Treasury Service of Ukraine, the State Statistics Service of Ukraine, the State Fiscal Service of Ukraine, the Armed Forces of Ukraine, the State Border Guard Service of Ukraine, the Police of Ukraine, and the Pension Fund of Ukraine. Based on the challenges and general trends revealed by the results of the analysis, the authors identified areas for improving collective wage bargaining and the best practices in social partnership for their dissemination in public organisations.

Internal Social Responsibility: An Assessment Based on Official Reporting Data

The authors have suggested analytical tools to evaluate levels of internal social responsibility by developing an aggregate set of indicators. The reference indicators values were substantiated on the basis of average industry ones, which provided an opportunity to determine the multiple coefficients. The suggested tools provide the opportunity to define enterprises’ tendency for change in the level of responsibility level by years. This research can have important practical impacts due to its quantitative assessment having been based on published financial statements. The study creates additional opportunities for stakeholders to evaluate current internal corporate social responsibility levels and predict their own development direction.

Еnvironmental and Socio-Demographic Consequences of the Chornobyl Nuclear Power Plant Accident: A Historical Retrospective after 36 Years

The accident at the Chornobyl Nuclear Power Plant was one of the largest in human history. It is often referred to as a global event because its effects were felt not only by Ukrainians but also by the populations of Belarus, Russia, Central Europe, the Balkans and the Scandinavian Peninsula. 2022 marked the 36th anniversary of this terrible occurrence, when the history of Ukraine in the late twentieth century was divided into two parts: before the tragedy of 26 April 1986, and after it.
Today, it is important for Ukrainian society not only to recognise the significance of the catastrophe and remember its victims but also to find ways to overcome its grave consequences. This requires comprehensive research useful for developing new approaches to minimising the environmental and socio-demographic problems caused by the Chornobyl tragedy. Thus, this research has practical scientific, humanitarian and socio-political significance. The novelty of the obtained results lies in the study’s critical rethinking of the achievements of predecessors and its analysis of historical sources concerning the environmental and socio-demographic consequences of the accident at the Chornobyl Nuclear Power Plant as they manifested from 1986 to 2022.
The methodological basis of the work is empirical cognition. The use of logical-analytical methods of grouping and typology allows us to classify homogeneous events and coherently present the material of the article. The study additionally uses comparative judgment, historical-statistical and problem-chronological methods. The principles of objectivity and impartiality also play an important role in the work.
The purpose of the study is to investigate the consequences of the Chornobyl Nuclear Power Plant accident on the environmental and socio-demographic aspects of the population of Ukraine from 1986 to 2022 based on the identified set of sources. From a historical perspective, the level of pollution in the territories of Ukraine is traced, the demographic situation is monitored, and parallels are drawn between the Chornobyl disaster and the increase in incurable diseases and mortality.
In conclusion, the authors note that although 36 years have passed, the echo of this catastrophe remains tangible for the population of Ukraine. Several issues still must be solved. The first is the return to life, namely, the safe living and management of areas that have been exposed to radiation contamination, as well as the continuation of work aimed at restoring agricultural soils. Second, purposeful work must be conducted by the state to minimise social and demographic problems resulting from the Chornobyl catastrophe. In our opinion, the government should increase expenditures aimed at providing quality medical services to the population of Ukraine, as well as conduct constant monitoring of the health of those people who are at high risk in order to better detect diseases in their early stages.
These groups of people include liquidators of the consequences of the accident and migrants. Such measures can stabilise the demographic situation by increasing birth rates and reducing mortality, as well as improve the health and living standards of the population of Ukraine.

Directions for Improving Ukrainian Legislation on Tourism in Post-War Times

It is expected that people from all over the world will visit Ukraine after its victory in the war against Russian aggression, turning Ukraine into a world-popular tourist destination. Hence, Ukrainian egislation on tourism must be improved in the post-war period. The authors analysed the current legislation on tourism in Ukraine and identified major problems that must be addressed systematically and those that should be settled in the post-war period in view of the post-war humanitarian, socio-economic, institutional, and cultural challenges. In this context, the authors proposed a set of changes to improve Ukraine’s legislation on tourism on the national and institutional levels. Such changes should positively impact other socio-economic processes of reconstruction in post-war Ukraine.

The Impact of War on the Reorientation of Trade Flows: The Case of Ukraine

The military aggression of the Russian Federation against Ukraine, which started in 2014 and came to another active phase in February 2022, may change Ukraine’s foreign trade in terms of both its geography and product structure. The regions of Ukraine will not only have to recover from the consequences of destruction, but also to seek new directions of foreign economic activity and build connections with reliable partners such as the European Union and the United States. The paper presents an analysis of changes in the foreign trade of Ukraine and its regions since 2014 and examines shifts in trade flows in the direction of Western leaders of global trade. The case of Georgia, another target of Russian military intervention, in the reorientation of its trade flows, is also considered.
