This paper discusses the feasibility of EU legal action in the field of electronic identity (eID) within the new distribution of legal competences and the provision of novel legal basis engendered by the Treaty of Lisbon. The article attempts to find a ‘legal anchor’ to the idea of a pan-European electronic identity within EU law, looking at the issues of competences and legal basis. After examining various different areas of competence and the most feasible (and probable) candidates for a legal basis supporting an EU legal framework for eID, the paper argues that the latter should be found in the combination of Article 16 TFEU (concerning the right to the protection of personal data) with Article 3 TUE, and Articles 26 and 114 TFEU (concerning the establishment and functioning of the Internal Market), which also constitute the area of competence where an eID legal initiative can be pursued. 相似文献

This article suggests that the consequences of the ??fragmentation?? of the European patent system are more dramatic than the mere prohibitive costs of maintaining a patent in force in many jurisdictions. The prevalence of national jurisdictions, which are highly heterogeneous in their costs and practices, over the validity and enforcement of European patents, induces a high level of uncertainty and an intense managerial complexity which reduce both the effectiveness and the attractiveness of the European patent system in its mission to stimulate innovation. 相似文献

Farming and agribusiness could help employ and reintegrate conflict-affected youth in regions recovering from civil conflict. This study addresses the constraints for youth to engage themselves in agribusiness in the worst conflict-affected regions of northern Uganda. Specifically, it explores to what extent beekeeping and honey business offer viable socio-economic opportunities to formerly displaced youth. Using a value chain approach, the study draws on in-depth interviews with 23 (young) key stakeholders in the honey value chain, document analysis and focus group discussions. The results suggest that apiculture business can create employment for conflict-affected youth in northern Uganda due to the relatively low entry barriers, a young enthused vanguard and higher returns per unit input compared to other agricultural sectors in the region. However in order to succeed, this group requires support from community elders, government and business facilitators, because, due to their age and war background, these youngsters face the common constraints to farming and agribusiness, but at higher degrees of severity. 相似文献

The case law of the CJEU on the economic free movement of people has departed from the traditional requirement that a nexus must be established between individual free movement and cross‐border economic activity, which has led to an extension of its scope. It is submitted that concerns with the protection of fundamental rights of European citizens are driving this process, and that the CJEU has sought to protect these fundamental rights through the market freedoms in two ways: by arguing that market freedoms are fundamental right themselves, and/or that European Citizenship has changed their normative underpinnings and status. This Article criticises both lines of argument, and defends a third: that the protection of these fundamental rights must be achieved at European level, if at all, through a conception of European Citizenship able to stand on its own. 相似文献

The analysis of amino acids present in fingerprints has been studied several times. In this paper, we report a method for the analysis of amino acids using an fluorenylmethyloxycarbonyl chloride‐derivatization for LC separation and MS detection. We have obtained good results with regard to the calibration curves and the limit of detection and LOQ for the target compounds. The extraction of the amino acids from the substrates used proved to be very efficient. Analysis of the derivatized amino acids enabled us to obtain full amino acid profiles for 20 donors. The intervariability is as expected rather large, with serine as the most abundant constituent, and when examining the total profile of the amino acids per donor, a characteristic pattern can be observed. Some amino acids were not detected in some donors, or fell out of the range of the calibration curve, where others showed a surprisingly high amount of material in the deposition analyses. Further investigations will have to address the intravariability of the amino acid profiles of the fingerprints from donors. By the development of the analytical method and the application to the analysis of fingerprints, we were able to gain insight in the variability of the constituents of fingerprints between the donors. 相似文献

ABSTRACTPrevious research has predominantly measured populist attitudes as a one-dimensional concept, tapping into the distinction between the ordinary people and the culprit elites. With growing differentiation of populist viewpoints across the globe, this unidimensional approach may not reflect the multifaceted reality of the people’s populism. Most importantly, albeit paramount in right-wing populist rhetoric, exclusionist perceptions of others threatening the monocultural nation of the people are typically not captured in one-dimensional conceptualizations. To assess more precisely how populist attitudes are structured, we collected original survey data (N?=?809) among a representative sample of Dutch citizens. Using Multidimensional Scaling and Confirmatory Factor Analysis, we propose a two-dimensional structure: anti-establishment and exclusionism. This study further demonstrates how salient these different populist attitudes are among which voters. 相似文献

The Belt and Road Initiative, proposed in 2013 by Chinese President Xi Jinping, improves cooperation among its participants in terms of both economic and cultural? devel-opment. Latin American countries started to join the initiative in 2017, and as of 2019, 19 of them signed related memoranda of understand-ing with China. 相似文献
