This article focuses on the interrelationship between homeland and diaspora at times of crisis. It adopts a comparative lens to look into diasporic (dis)engagement with the homeland, specifically analysing the cases of Greece and Ukraine. The main research issues are how crises affect the engagement between homeland and diaspora – taking Greece and Ukraine as case studies – and which the defining contextual factors are that transform the diaspora engagement. The article unpacks the homeland–diaspora nexus concerning two states with different socio-political backgrounds, both going through severe political and economic crises. In so doing, the article gives prominence to the differentiation between the en-gagement of the two different diasporas with their home countries at times of crisis. Evidence suggests substantial engagement in the Ukrainian case while, in the Greek case, a more mixed attitude – leaning towards disengagement – is apparent.

In the present study a severe outbreak of hemorrhagic pneumonia (HP) in neonatal minks concomitant with Leismania infantum (L. infantum) detection is reported. The outbreak took place on a Greek mink farm and affected 1,362 mink kits, with 524 dying. Macroscopic lesions of 14 necropsied affected kits were confined to the respiratory system with dark red, consolidated lung lobes and to the small intestine with severe, acute, hemorrhagic and necrotic enteritis. Microscopic examination of lung sections revealed severe hemorrhagic pyogranulomatous pneumonia. Bacteria were obtained in pure culture from the lungs of all necropsied animals and were confirmed as Pseudomonas aeruginosa (P. aeruginosa). Three out of 14 (21.4%) animals were positive for the presence of L. infantum DNA. The outbreak was attributed to the infection of minks with P. aeruginosa, possibly as a consequence of being immuno-suppressed by L. infantum. Further research is necessary, especially on the pathogenesis of P. aeruginosa/L. infantum co-infection and the implications of this interaction on HP disease outcome.

The following paper presents the process of decarbonization of the energy sector in Greece and points out to different methods the Greek authorities are adopting in order to reduce the emission of greenhouse gases generated by electricity production. Greece is a country which is modernizing its energy sector gradually, yet dynamically. One of the prime aims is to reduce the level of energy produced in coal-fired power plants by focusing on the renewable energy and the gas sector. In 2010 still more than half of the electrical energy was generated by lignite-fired power plants. Almost ten years later the ratio has dropped to only slightly more than 30%. A significant reduction in coal consumption was possible thanks to investments in renewable energy sources, especially in the wind and solar energy sectors. Both sectors have seen a large increase in production, making renewable energy sources already accounting for over 20% of Greek electricity production. Capital-intensive investments were also made in the country’s gas supply through the expansion of gas-fired power plants and gas transmission networks. As a result, natural gas remains the main source of energy for Greece next to coal. Unfortunately, a big challenge in terms of decarbonization is the need for increased imports of electricity from abroad, due to the insufficient capacity of the Greek energy sector. Therefore, the main purpose of this paper is to define a Greek model of decarbonization and to point out to its benefits and dangers. Greek strategy might serve as an example of how to successfully solve the energy issues in the countries with similar energy profile.

The aim of the paper is to describe the main patterns and challenges of Ukrainian migration to Greece with reference to the consequences of the recent economic and social crisis in the host country on the migrants’ lives. Specifically, the paper discusses the impact of the legal framework related to migra-tion in four different periods. Historically, Greece was one of the first destinations attracting Ukraini-an migrants, but the migration flows have strongly decreased during the last years and a tendency for return migration has emerged. Among the key features is the fact that the migrant’s experience is deeply influenced and shaped by Greece’s policy response to migration. The paper will therefore spe-cifically examine the impact of the legislative measures on the mobility of the migrants.

This article has three objectives. The first one is to compare and interpret the exceptionally large social and economic costs of policy errors by central authorities in Greece 2000–2010, Poland 1970–1980 and the G7 countries 2000–2010. The second objective is to analyse the risks to the pace and stability of Poland’s economic growth and the state of public finances after 2020. The third objective is to propose policy adjustments in responses to these risks in the period 2023–2030.
