The article presents an innovative solution of a two-unit rail vehicle system for passanger transport with a dual-drive, diesel engine and electric motor. The vehicle was designed as a combination of two units, one dedicated to each of the two drive systems, where one unit provides electric drive while the other a combustion engine. The selection of engine and drive components was presented along with the aftertreatment systems used in the design. The provided solution was created in response to the dynamic needs of rail vehicle operators in the European Union who aim to reduce exhaust emissions without compomising the reach of the existing rail networks.

The main aim of this article is to identify certain specificity in self-employment of foreigners in EU countries and to find out whether the differences in self-employment of foreigners between countries are diminishing. Within the main objective, we have set two sub-objectives. The first sub-objective is to compare EU countries on the basis of the following indicators: 1/ number of self-employed foreigners and 2/ share of self-employed foreigners in employed persons from foreign countries. The second sub-objective is to determine whether EU countries converge in the number of the share of self-employed foreigners in the number of employed persons from foreign countries. We have confirmed that the countries have a tendency to convergence in regard to the share of self-employed foreigners in employed persons from foreign countries. We assume that this tendency can also be due to the pressure of the labour market that shows a lack of labour force. The share of self-employed migrants is relatively high in Eastern Europe. On the other hand, their increase is below average compared to the EU.

The development of road network infrastructure is an important component of the economic development of the European Union. Updating of the road network contributes to the integration of the economies of countries into a coherent whole. The road network provides the free movement of citizens, the movement of goods and the effective implementation of various services. The increase in the length of the road network leads to an increase in the financial and material costs necessary to ensure its maintenance and repair. One of the ways to reduce costs is by strengthening the physic-mechanical and operational characteristics of the pavement due to the widespread use of cement concrete. The quality of the pavement of cement concrete depends largely on the rational selection of its composition. This allows a significant increase in the durability of road pavement. The purpose of the research was: the development of recommendations for the rational selection of the composition of the road pavement material of cement concrete, aimed at upgrading longevity, and taking into account its frost resistance grade. According to the goal, the following tasks were developed: the analyses of the climatic zones in which the road network of the European Union is located; the development of a research plan, a selection of the response function and influence factors; the study of physico-mechanical and operational characteristics of the researched material of road pavement; on the basis of the obtained data, the calculation of the complex of experimental-statistical models, which describe the physico-mechanical and operational characteristics of the road pavement material; on the basis of experimental statistical models, a method was proposed for selecting the rational compositions of the cement concrete pavement road material depending on the conditions of its application. The results presented in the article can be used in engineering and scientific practice for the selection of road pavement from cement concrete for highways.

This survey considers the emergence of English as a language shared across the European Union in particular and the European continent at large, and together with its distinctive ‘lingua franca’ dimension among the mainland European nations. It considers in particular the situation of ‘non-native speakers’ who regularly use the language as well as the concept of a ‘Euro-English’ in general and the Swedish, ‘Swenglish’ and English relationship on the other. It concludes by considering the liberation of non-native users from ‘the beginning of native-speaker norms’.

This article reviews the way in which the concept of precaution, as commonly referenced in EU law, is received in the WTO. It argues that precaution is not a principle, but one facet of a principle of making rational judgments based on available information, the other facet of which is “that risk is worth taking”. Systematically pursuing high cost measures in response to low risks is not a balanced approach, and has probably contributed to the scepticism with which the concept is viewed in the WTO. However, this article goes on to argue that, without needing to be a principle, precaution is the determining legal feature in the SPS Agreement, because, unlike in the European Union, there is no legislative harmonisation of SPS measures at international level, WTO Members being free to set their own appropriate level of protection. In fact, the concept of precaution is relevant in the context of many other WTO provisions and is in some respects quite close to the concept of subsidiarity. Notwithstanding this, the first WTO SPS cases, driven by regulatory exporters and an interventionist WTO, have excessively emphasised scientific issues, masking policy judgments that the WTO has neither the legal nor the political authority to sustain. The article concludes that the proper way forward necessitates closer political, legal and administrative links between the WTO and other relevant international organisations, and a move away from consensus in the latter.

This article examines the influence of the European Parliament (EP) within the legislative process of the European Union. Although debate over the impact of the cooperation and co-decision I procedures continues, this article argues that, in part, the current theoretical debate is a false one that has caused many of the other important variables that affect EP legislative influence to be ignored. This article briefly revisits the current debate, then proceeds to an analysis of the success of more than 1,000 EP amendments under the cooperation and co-decision procedures. This evidence suggests that numerous other variables, such as internal EP unity and type of amendment made, have a significant impact on EP success, even controlling for procedure. In addition, this comparison points out some empirical differences between the two procedures that have been largely ignored in the theoretical debate but that nonetheless have a significant impact of EP success and merit further study.

The article analyses the process of EU enlargement with reference to the progress that Bulgaria and Romania have made within it. It is argued that leaving them out of the wave of accession finalised in May 2004 for ten of the candidate states, has placed them in a situation of double exclusion. Firstly, their geographical belonging to the region of Southeast Europe has been rendered non-essential by their advanced position within the EU enlargement process. Secondly, their achievement in economic and political transition has been removed from the progress of the ten states, which joined the EU in May 2004 by delaying the time of their accession. As a result, any efforts in regional cooperation and integration between Bulgaria and Romania on one hand, and other Southeast European states on the other, have been effectively cancelled. Moreover, in current European politics, the two countries have come to serve the unenviable role of exemplifying on the part of the European Union how progress is being awarded and hesitation punished.

Euthanasia is one of the issues that bioethics deals with, which is one of the outmost importance. Furthermore it is very up-to-date. In Greece and in most countries of the European Union euthanasia has not been subject to specialized legislation. It is only occasionally debated, resulting in tension and conflict. On one hand, people have the right to self determination, so the end of life should be among them. On the other hand, life is considered to be of the highest value and it is the duty of healthcare personnel to guard and preserve it by any means, using their expertise and knowledge.In this paper, a brief report is made to the practices used across countries in the European Union regarding the end of life. Most countries are opposed to euthanasia while acknowledging the right of a patient to refuse or receive treatment. Only three countries have passed bills that legalize euthanasia under strict conditions. The rest, due to sensitivity in this matter, have not yet proceeded in reforming their laws accordingly. It seems that society does not have the necessary reassurances so that they can engulf that issue guarding the true will of a person.

The paper is dedicated to the differences between the classical instruments for regulating interstate political and trade-economic relations from those used in the development of regional integration processes. Traditionally, the Eurasian Economic Union is compared with the European Union, considering the EU as a close example to follow in the development of integration processes. At the same time, there exist the other models of integration. The author proposes to pay attention to the other models of integration and based on the analysis of documents, reveals the experience of Northern Europe, which demonstrates effective cooperation without infringing on the sovereignty of the participants. The author examines the features of the integration experience of the Nordic countries in relation to the possibility of using its elements in the modern integration practice of the Eurasian Economic Union.

The inability of the European Union (EU) to grow has raised questions regarding the effectiveness of competitiveness and growth policies. To increase efficacy, the EU has determined that regions must undergo an exercise in smart specialization and devise a strategy for the same. However, particularly in follower regions facing severe locked-in problems and structural bottlenecks, the application of smart specialization may require adjustments and a more dynamic vision, especially with regard to the follower regions. Furthermore, many operational issues arise in the programming and policy-devising stages. This article aims to contribute to this debate by proposing a framework to guide the selection of priorities and by applying the proposed framework to the Portuguese North region.
