On 26 July 2017, the Grand Chamber of the European Court of Justice rendered its seminal Opinion 1/15 about the agreement on Passenger Name Record data between the EU and Canada. The Grand Chamber considered that the decision of the Council about the conclusion, on behalf of the Union, of the agreement between the EU and Canada about the transfer and processing of PNR data must be based jointly on Article 16(2) about the protection of personal data and Article 87(2)(a) about police co-operation among member states in criminal matters, but not on Article 82(1)(d) about judicial co-operation in criminal matters in the EU of the Treaty on the Functioning of the EU. The Grand Chamber also considered that the agreement is incompatible with Article 7 on the right to respect for private life, Article 8 on the right to the protection of personal data, Article 21 on non-discrimination and Article 52(1) on the principle of proportionality of the Charter of Fundamental Rights of the EU since it does not preclude the transfer, use and retention of sensitive data. In addition to the requirement to exclude such data, the Grand Chamber listed seven requirements that the agreement must include, specify, limit or guarantee to be compatible with the Charter.The opinion of the Grand Chamber has far-reaching implications for the agreement on PNR data between the EU and Canada. It has also far-reaching implications for international agreements on PNR data between the EU and other third states. Last, it has far-reaching implications for Directive 681 of 27 April 2016 on PNR data.  相似文献

This article begins by explaining why the United Nations' civilian protection agenda is particularly relevant and important for Africa and why the Responsibility to Protect (R2P) might be said to be an African norm export to the rest of the world. Next, it traces the reasons for peace operations' reluctance to use force. It then shows how the civilian protection agenda has tried to fill critical gaps in the existing normative architecture, with both R2P and the Protection of Civilians (POC) resulting from growing shame at the accumulating list of atrocities in which the international community stood by as passive onlookers, frustrations at the ‘constitutional’ constraints and normative inadequacies rather than indifference and apathy to the plight of civilian victims that produced the passivity, and a determination to reposition the United Nations system to be empowered and capacitated to be able to respond better on both the timeliness and effectiveness dimensions when confronted by repeat occurrences of similar tragedies. The fourth section discusses the merits of the R2P and POC norms in responding to the challenge of civilian protection. The final part notes that, despite these two valuable additions to the repertoire of the international community in dealing with atrocities perpetrated on civilians, there remain many gaps in the protection agenda, as shown in several recent cases.  相似文献

Abstract

In this study, the internal reliability and construct validity of the recently adapted Swedish version of the Novaco Anger Scale (NAS-1998-S; Lindqvist, Dåderman, & Hellström, Social Behavior and Personality, 8, 773–788, 2003), as well as its scale correlations with demographic and criminality variables, were investigated. Construct validity was established by assessing the correlation pattern of the scales of NAS-1998-S with concurrent scales of similar and distinct constructs. Ninety-five male violent prisoners, ranging in age from 18 to 67 years, participated. The results demonstrated good internal reliability, consistent intrascale relationships, and appropriate construct validity of NAS-1998-S. The number of previous convictions had a moderate negative relationship with the capacity of control. Age and education correlated negatively with the NAS-1998-S scales, except Regulation. In addition to psychometric issues, the results were discussed from a clinical perspective on the offender population.  相似文献

The stability of two benzisoxazole antipsychotics was determined in vitro in decomposing porcine blood inoculated with bacteria, utilizing a high‐performance liquid chromatography with ultraviolet and fluorescence detection method for drug quantitation. Stability experiments for risperidone and paliperidone were conducted at 7, 20 and 37°C for 4 days using sterile and bacterially inoculated porcine blood. The drugs were stable in sterile blood at each temperature and in inoculated blood at 7°C, but degraded significantly in inoculated blood at 20 and 37°C. Complete loss occurred within 2 days when incubated at 37°C. The benzisoxazole‐cleaved degradation products for both drugs were identified as 2‐hydroxybenzoyl‐risperidone and 2‐hydroxybenzoyl‐paliperidone utilizing liquid chromatography quadrupole‐time‐of‐flight mass spectrometry and accurate mass measurements. The degradation products have been found in postmortem case studies, including one case where risperidone and paliperidone were not detected, indicating complete conversion can occur in situ.  相似文献

The political economy of Britain over the past three decades provides an interesting example of the consolidation, normalization and institutionalization of a new economic paradigm – neoliberalism. As such, it serves as a potentially instructive focus for debate both about the conditions under which economic paradigms are replaced and consolidated and the evolution of such paradigms through the process of institutionalization. In this paper I suggest that the institutionalization of this new economic paradigm has been associated with the shift from a normative to a normalized and necessitarian neoliberalism. I examine the role played by rationalist assumptions in this extended process of normalization-institutionalization. After presenting a stylized account of the evolution of British neoliberalism, I show how New Labour's monetary policy regime is the heir to the legacy of monetarism and its agenda of labour-market reform is the heir to Thatcherism's supply-side economics. I suggest that the time-inconsistency thesis and the business school globalization thesis have played an equivalent role, for New Labour, to that played for the new right by monetarism and supply-side economics in legitimating neoliberalism. In this way neoliberalism has been normalized. In the final sections of the paper I reflect on the implications of the normalized and necessitarian character of neoliberalism in Britain for its contestability and for democratic economic governance more broadly.  相似文献

Abstract:  The forkhead box P2 ( FOXP2 ) gene is specifically involved in speech and language development in humans. The sequence is well conserved among many vertebrate species but has accumulated amino acid changes in the human lineage. The aim of this study was to develop a simple method to discriminate between human and nonhuman vertebrate DNA in forensic specimens by amplification of a human-specific genomic region. In the present study, we designed an allele-specific polymerase chain reaction (PCR) using primers to amplify smaller than 70-bp regions of FOXP2 to identify DNA as being of human or nonhuman, including ape, origin. PCR amplification was also successfully performed using fluorescence-labeled primers, and this method allows a single PCR reaction with a genomic DNA sample as small as 0.01 ng. This system also identified the presence of human DNA in two blood stains stored for 20 and 38 years. The results suggested the potential usefulness of FOXP2 as an identifier of human DNA in forensic samples.  相似文献

Abstract:  The AmpFℓSTR® MiniFiler™ polymerase chain reaction amplification kit, developed and supplied by Applied Biosystems, complements the AmpFℓSTR® Identifiler® polymerase chain reaction amplification kit (Applied Biosystems, Warrington, U.K.) by improving the success rate when profiling DNA that is degraded or contains inhibitors. Before applying the MiniFiler™ kit to casework, the profiles from 200 unrelated Kuwaitis were compared to Identifiler® profiles. Concordance was observed for 99.875% (1598 of 1600) of the compared STR loci. The two discordant profiles displayed allelic dropout: one at the D13S317 locus due to nonamplification of allele 10 in the MiniFiler™ profile, and one at the D18S51 locus due to nonamplification of allele 18 in the Identifiler® profile.  相似文献
