The need for decreasing carbon emissions in the transportation sector in order to meet the targets of the European Union by 2030, inevitably leads to the large scale adoption of cleaner alternatives. Hydrogen fueled vehicles could possibly provide one such alternative, if we could assume that the necessary infrastructure would be widely available throughout Europe. Already, the European Union has committed to the construction of a significant number of Hydrogen Refueling Stations (HRS) by year 2025 and in view of that, there is a need of developing suitable configurations for the production, compression, storage and dispensing of green hydrogen to hydrogen fueled vehicles. This work presents an autonomous hybrid system which produces green hydrogen by PV- powered water electrolysis (PEM), which is subsequently compressed by a novel metal hydride hydrogen compressor to pressures up to 200 bar. This pilot HRS will meet the daily demand of 2 scooters and a golf cart which have been transformed, in order for their electric motor to be powered by a hydrogen fuel cell instead of a battery. An important element of the work which is presented, revolves around the integration of the metal hydride compressor with the rest of the system, and how this integration won’t hinder its functionality. The complete system design and layout is presented, while the results from the system operation could give a good idea regarding the optimal system sizing for similar large scale applications.

The article describes and sets the definition of different farm models under the categories of being family, small, and large-scale commercial farms. The distinction was based on the structure of the workforce and the relationship between agricultural income and the minimum wage. Family farms were dominated by the farming family providing the labour and their income per capita exceeded the net minimum wage in the country. The larger commercial farms feature a predominance of hired labour. Based on surveys, it was found that in 2016 in the EU-28 there were 10,467,000 farms (EU-13—57.3%, EU-15—42.7%). They carried out agricultural activities on an area of 173,338,000 ha (EU-13—28.5%, EU-15—71.5%). Countries of the EU-28 generated a standard output (SO) amounting to EUR 364,118,827,100 (EU-13—17.2% and EU-15—82.8%). After the delimitation, it was shown that small farming (70.8%) was the predominant form of management in the European Union (EU-13—88.2% and EU-15—79.8%) compared to family farming (18.4%) (EU-13—10.5% and EU-15—29%). In most EU countries the largest share of land resources pertains to small farms (35.6%) and family farms (38.6%) (UAA—utilised agricultural area of farms).

Voter Fraud

This chapter summarizes the main analytical moves in the TRUST heuristic for analyzing untruthfulness. It then applies the heuristic to three short texts that have been widely called out as lies: Trump’s tweet about large-scale voter fraud just before the 2016 presidential elections; the “Brexit Battle Bus” claim that the United Kingdom sent £350 million per week to the European Union; and Tony Blair’s 2002 statement to Parliament about Iraq possessing weapons of mass destruction. The cases share a common theme: the capacity of untruthful public discourse to undermine democratic legitimacy by, respectively, questioning the integrity of electoral procedures, harming the capacity of voters to make a rational choice, and undermining faith in the rational and responsible deliberation of one’s leaders. The chapter troubles the simple attribution of lying in these cases and shows how a TRUST analysis can lead to a deeper understanding of the types and ethical value of untruthfulness.

AbstractFocusing events are sudden, striking large-scale occurrences that attract political attention. However, not all potential focusing events appear on the agenda. Combining data from multiple sources, this study conducts an analysis of the determinants of prioritisation of external focusing events in the European Council over a period longer than two decades. The results demonstrate that decisions regarding the placement of crises on the agenda are underscored by exogenous (humanitarian) and endogenous (geopolitical interest) considerations. Those events with a higher likelihood of agenda access include manmade incidents (versus natural disasters), events with larger death tolls and crises in the neighbourhood. Stronger competition between potential focusing events across time and space reduces the chances of access. The level of attention each event receives depends on purely strategic interests. Focusing events in neighbouring countries gain a higher portion of attention, as do occurrences in states having a larger trade exchange with the European Union.

During 2021, different worldwide initiatives have been established for the development of digital vaccination certificates to alleviate the restrictions associated with the COVID-19 pandemic to vaccinated individuals. Although diverse technologies can be considered for the deployment of such certificates, the use of blockchain has been suggested as a promising approach due to its decentralization and transparency features. However, the proposed solutions often lack realistic experimental evaluation that could help to determine possible practical challenges for the deployment of a blockchain platform for this purpose. To fill this gap, this work introduces a scalable, blockchain-based platform for the secure sharing of COVID-19 or other disease vaccination certificates. As an indicative use case, we emulate a large-scale deployment by considering the countries of the European Union. The platform is evaluated through extensive experiments measuring computing resource usage, network response time, and bandwidth. Based on the results, the proposed scheme shows satisfactory performance across all major evaluation criteria, suggesting that it can set the pace for real implementations. Vis-à-vis the related work, the proposed platform is novel, especially through the prism of a large-scale, full-fledged implementation and its assessment.

Eu Regulation

The process of establishing normative acts in the European Union does not  occur out of nowhere, but in the context of specific social needs. That was the case of the genesis of establishing legal regulations regarding the protection of personal data in the European Union. Socio-economic integration, which resulted from the functioning of internal market in the European Union, has led to a significant increase in cross-border transfers of personal data. It led to situation in which various economic operators or state institutions of the Member States have increasingly processed the personal data of the EU citizens. Within time, these data have become an equally valuable commodity - not to say even more valuable – compared to goods and services (Costa-Cabral, and Lynskey Orla, 2017, p. 11). Making use of personal data on a large scale especially by public and private entities, associations and companies over time has posed a threat to the security of personal data. This has made it necessary to introduce legal protection measures for personal data in the European Union that would eliminate the negative effects of any form of personal data processing. The purpose of this article is to evaluate legal regulations regarding legislative protection of personal data in the European Union against the background of EU Regulation 2016/679 of the European Parliament and the Council with respect to the protection of individuals due to processing personal data, its free movement and repealing Directive 95/46/EC (hereinafter referred to as Regulation 2016/679). Due to initially adopted purpose of the considerations there arose a problem which was formulated in the form of a question: Do the legal measures introduced by the Regulation constitute an effective tool for the protection of personal data in the event of a violation of the law by personal data administrators and entities while processing such data? The presented purpose of the considerations and the research problem determined the order of the analysis.

Political Communities

The recent global surge in large-scale foreign land acquisitions marks a radical transformation of the global economic and political landscape. Since land that attracts capital often becomes the site of expulsions and displacement, it also leads to new forms of migration. In this paper, I explore this connection from the perspective of a political philosopher. I argue that changes in global land governance unsettle the congruence of political community and bounded territory that we often take for granted. As a case study, I discuss the European Union’s Renewable Energy Directive as a significant driver of foreign land acquisitions. Using its global power, the European Union (EU) is effectively governing land far outside of its international borders and with it the people who live on this land or are expelled from it. As a result, EU citizens ought to consider such people fellow members of their political community. This has implications for normative debates about immigration and, in particular, for arguments that appeal to collective self-determination to justify a right of political communities to exclude newcomers. The political community to which EU citizens belong reaches far beyond the EU’s official borders.
