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

Indigenous movements have increasingly turned to the global arena to achieve their political goals at the national level. Using the norm diffusion model, the present article analyzes the relationship between the international indigenous rights regime (IRR) and the conceptualizations of indigenous territory used by four Mapuche organizations in Chile over the last 10 years. We find that the organizations draw on the IRR to frame their demand for autonomous territories based on historical Mapuche practices. We identify two conceptualizations: (1) a larger territory with political but not economic autonomy and (2) a smaller natural-cultural space characterized by a distinctive economic logic.  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

This paper argues that the positive allocative decisions paradigmatically carried out by the application of legal rules are a necessary condition for arguments about particular justice (i.e., distributive and commutative justice) to make sense. If one shifts the focus from the distinction between distributive and commutative justice to what the two aspects of particular justice are for, namely, providing criteria to judge the allocation of goods, it becomes clear that the distinction is conceptually unstable. The paper argues that stabilizing the distinction is worthwhile and that this can only be accomplished by the introduction of positive allocation schemes.  相似文献

ABSTRACT

Previous 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

This article argues that the agrarian expansion that took place in Chile's southern frontier region after the military occupation of the Mapuche territory (1862–1883) was the first phase of the development of agrarian capitalism in the region. This process was shaped by ecological conditions. In a territory covered by forests, sharecropping with tenant labourers was crucial for land clearance in the formation of the hacienda system, when landowners needed to create fields for commercial crops. As the domestic demand for agricultural products increased, mechanisation intensified, sharecropping declined, and wage labour became dominant. Frontier capitalist agriculture expanded dramatically, and consequently the region became the breadbasket of Chile.  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

The secondary dentin deposition that occurs after the tooth formation process results in a decrease in pulp cavity volume in adolescents and adults. The purpose of this critical review was to correlate pulpal and/or dental volume on cone-beam computed tomography (CBCT) with chronological age approximation. A subobjective was to investigate which methodology and CBCT technical parameters would be most appropriate to evaluate this correlation. This critical review followed the PRISMA guidelines, and it was conducted by a search through PubMed, Embase, SciELO, Scopus, Web of Science, Cochrane Library databases, as well as gray literature. Primary studies that used pulp volume, or pulp chamber to tooth volume ratio measured using CBCT were included. Seven hundred and eight indexed and 31 non-indexed records were identified. A qualitative analysis was performed including 25 selected studies with a total of 5100 individuals, age ranging from 8 to 87 years without sex predilection. The most used method was pulp volume/tooth volume. CBCT voxel size ranged between 0.09 and 0.5. Manual segmentation associated with threshold algorithms was used in most of the studies. Correlation between the pulp volume/tooth volume ratio was moderate: −0.66 for the upper central incisors, −0.59 for upper canines and −0.56 for lower canines. High heterogeneity was observed among the studies. It is concluded that pulp volume should be used with caution in age estimation. Evidence supports the preferable use of upper incisors with pulp volume/tooth volume ratio for age estimation. There is not enough evidence that voxel size interferes in age estimation by pulp volume.  相似文献
