By exploring how early political investments in favor of a European Constitution have been turned into a legal enterprise to constitutionalize the European treaties, this article analyzes the changing role of legal elites in the genesis of a European transnational order. At first, legal activities of constitution-making were closely linked to military issues and political mobilizations; later, the legal work of constitutionalization took a different path as a result of the process of differentiation of the European field of power and of the internal and contradictory logics of a newly created legal institution, the European Court of Justice (ECJ). By reconstructing the constitutionalization process, this article highlights the various types of elites then competing for the early definition of a European transnational order and, in particular, the capitals and representations of legal agents in the making of a Constitution for Europe.  相似文献

With the rapid growth of cross-border competition among currencies, informed observers predict that the new monetary unions are virtually inevitable in many parts of the world. In fact, predictions of such alliances are misleading and almost certainly wrong. Monetary unions necessarily imply a measure of collective action in the issue and management of money. An alliance requires allies—other states with similar preferences and a disposition to act cooperatively. A survey of proposed monetary unions shows that willing partners among sovereign states are just not all that plentiful. Conceivably some governments could be attracted to less demanding forms of monetary alliance, depending on bargaining context. But prospects for many full new monetary unions are dim at best.  相似文献

An analytical method using solid-phase extraction (SPE) and high-performance liquid chromatography–mass spectrometry (LC–MS) has been developed and validated for the confirmation of Δ9-tetrahydrocannabinol (THC) in oral fluid samples. Oral fluid was extracted using Bond Elut LRC-Certify solid-phase extraction columns (10 cm3, 300 mg) and elution performed with n-hexane/ethyl acetate. Quantitation made use of the selected ion-recording mode (SIR) using the most abundant characteristic ion [THC + H+], m/z 315.31 and the fragment ion, m/z 193.13 for confirmation, and m/z 318.00 for the protonated internal standard, [d3-THC + H+]. The method proved to be precise for THC, in terms of both intra-day and inter-day analyses, with coefficients of variation less than 10%, and the calculated extraction efficiencies for THC ranged from 76 to 83%. Calibration standards spiked with THC between 2 and 100 ng/mL showed a linear relationship (r2 = 0.999). The method presented was applied to the oral fluid samples taken from the volunteers during the largest music event in Portugal, named Rock in Rio-Lisboa. Oral fluid was collected from 40 persons by expectoration and with Salivette®. In 55% of the samples obtained by expectorating, THC was detected with concentration ranges from 1033 to 6552 ng/mL and in 45% of cases THC was detected at concentrations between 51 and 937 ng/mL. However, using Salivette® collection, 26 of the 40 cases had an undetectable THC.  相似文献

Transfer trauma is alleged to be an increase in morbidity and mortality in institutionally relocated chronically ill elderly. Efforts by the legal profession to persuade courts that transfer trauma should be a legally recognized phenomenon invoking judicial protections against transfer (the "transfer trauma argument") have been unproductive. In O'Bannon v. Town Court Nursing Center, Inc., the United States Supreme Court denied standing to elderly persons claiming a property interest in remaining in alleged substandard facilities. The Court rejected the argument that the possibility of transfer trauma constituted a deprivation of life or liberty that would have required due process protections of notice and hearing. Despite the Court's preclusion of transfer trauma litigation in a constitutional context and the general unwillingness of lower courts to recognize the phenomenon, attorneys continue to burden the judicial system with frivolous transfer trauma arguments. The unfruitful pursuit of a judicial remedy for the ethical and social problems that arise with relocation of the elderly continues, in part, because of a misguided belief that this distressing social phenomenon is best remedied by the courts. Judicial unwillingness to recognize the transfer trauma argument, however, does not preclude legislative consideration of the humanitarian issues concerning the institutional relocation of elderly persons. This Article examines gerontological research in order to understand the judicial rejection of the transfer trauma argument and argues in support of legislative and educational solutions for the ethical and social problems attending transfer.  相似文献

In this essay we shall examine the contemporary jurisprudential thinking and legal precedents surrounding the issue of the sanctionability of pornography. We shall catalogue them by their logical presumptions, such as whether they view pornography as speech or act, whether they view pornography as obscenity, political hate-speech or anomalous other, whether they would scrutinize legislation governing pornography by a balancing of the harm of repression against the harm of permission, and who exactly they view as the victims.We shall take a special interest in the most recent, but unsuccessful, attempt by a subgroup of feminists to proscribe pornography by treating it as neither political speech nor sexual speech but speech which causes harm which is both political and sexual. They would like it to be considered as a special kind of odious propaganda undeserving of protection because it promulgates a mental state conducive to criminal activity, and hence is criminal in and of itself. However, the repression of propaganda, even odious propaganda, is not so easily accomplished in this country.Most anti-censors have emphasized the uncertainty of the causal connection between pornography and sexual violence. We shall contend that this is not the essential issue, and that, even if we agree with the allegations of pornography's prurient non-intellectual appeal and its tendency to excite criminal hostility, the current understanding of the Bill of Rights allows sanctioning only under the stringent requirement of the showing of a clear and present danger of specific and immediate acts.We raise the question of whether there should be a new standard for speech which is simultaneously political and sexual, and/or for speech whose harmful message is presented subliminally, on the grounds that such speech may not be adequately opposed by counter speech in the marketplace of ideas.  相似文献
