Authors: Myamlin S. V. , Baranovskyi D. M.
Published: May 2023

It is proved in a theory that the wear intensity of tribosystem of diesels of the special-purpose self-propelled railway rolling stock at laser modification will diminish at growth of concentration of surplus vacancies in superficial layers. Thus there will be the process of crawling over the vacancies and dislocations in the adjacent superficial layers of diesel tribosystems, i.e. running the processes of self-organization. The latter can be achieved at application of discrete laser modification of working surfaces of diesel tribosystems with carbon as a basic element in the form of carbon dioxide or natural graphite with niobium.

The essence of political myths, their structure and key functions have been analyzed in the article. The peculiarities of the political myths’ creation in the Ukrainian society have been also characterized. It has been determined that political myths are an effective tool of influencing the political culture and consciousness of the citizens and that they are being used by the present-day Ukrainian politicians in order to gain and keep power. The attention to the predominantly destructive role of political myths in the development of modern Ukrainian society has also been drawn in the article. The authors claim that with the development of the information society a political myth is becoming more adaptive and gains the ability to create an illusion of reality and its manipulative influence is becoming more masterly and less noticeable. This influence often leads to the simulation of the democratic principles, depression and passive attitude of the citizens. It is possible to minimize the social consciousness manipulation through raising the level of the political culture and consciousness of the citizens, forming an open communication system between authorities and citizens, developing independent mass media, etc.
Jaka wolność? Nierozwiązany dylemat demokracji
Authors:   Poseł na Sejm Rzeczypospolitej Polskiej, Lamczyk Stanisław
Published: May 2023

Since the ancient times there has been a continuing discourse on the nature and scope of freedom and civic and human right in the more or less liberal democracy. This paper contains a critical analysis and assessment of the most important opinions concerning the both political and economic freedom and the interpretations of that concept in the political practice. This article argues that, contrary to the beliefs of most people, freedom and human rights do not come from nature, but they are the result of the society’s consensus, especially that part of the society, which participates in the elections. The voters agree to allow the winning political party to realize its program also in the respect to freedom and civic (human) rights. On the other hand the politicians try to secure the appropriate equilibrium between the political and economic freedom, which supports the stabilization of a given political system and is conducive to the economic growth.
Państwa członkowskie Unii Europejskiej: nowy paradygmat suwerenności? Zarys problemu
Authors:   Akademia Ignatianum w Krakowie, Nuzzo Beata
Published: May 2023

Political and economic integration of countries taking place within the European Union leads to the modification of certain traditional features of the state’s sovereignty, such as, for example, exclusive judiciary competence within the state’s territory or independent financial, budget and fiscal policy. This calls for the analysis whether, and if so, to what extent, being the EU member state influences the country’s sovereignty. There are two contrasting views regarding this matter: some theoreticians claim that this integration limits or even eliminates the country’s sovereignty, while others argue that countries retain their sovereignty, and integration is the manifestation of sovereignty. The aim of the article is to reflect on these theories in the context of a new paradigm of EU member states’s sovereignty, which takes into account new relations between such agents as an individual, society, nation, or state.

Balança comercial e taxa de câmbio real: uma análise de co-integração
Authors: NUNES JOÃO MARCUS MARINHO
Published: May 2023

Resumo Este artigo utiliza a metodologia de cointegração para testar a proposição teórica de que existe uma relação de longo prazo entre a balança comercial e a taxa de câmbio real. Várias das definições comumente usadas da taxa de câmbio real foram testadas, mas nenhuma mostrou cointegração com a balança comercial. A única medida da taxa de câmbio real que foi cointegrada com a balança comercial foi aquela definida pelo preço relativo dos itens comercializáveis e não comercializáveis. As evidências não são inconsistentes com a observação de que a direção da causalidade vai da taxa de câmbio real para a balança comercial.

A renda mínima garantida como proposta para remover a pobreza no Brasil
Authors: SUPLICY EDUARDO MATARAZZO , CURY SAMIR
Published: May 2023

Resumo A economia brasileira continua apresentando a distribuição de renda mais desigual entre todos os países do mundo. O artigo apresenta as consequências das crescentes disparidades e considera os prós e os contras da introdução de um Programa de Rendimento Mínimo Garantido, através de um imposto negativo sobre o rendimento, como um instrumento eficaz para eliminar a pobreza. A segunda parte deste trabalho identifica uma estrutura analítica que poderia reproduzir os efeitos, ao nível da estrutura produtiva, de um processo de Distribuição de Renda. O objetivo foi alcançado a partir da escolha de um Modelo Input-Output que utilizou uma ampliação do Modelo básico de Leontief (1951), a partir de uma derivação da matriz de contabilidade social, resultando em uma estimativa dos multiplicadores desagregados para produção, receita e emprego.
