Conclusion The creation of improved systems of world order requires great care. Alternative configurations may or may not prove more suitable, and each must be painstakingly examined on its own merits. For those of us who are actively concerned with studying about world order, this means the application of a far more rigorous conception of inquiry to our subject. So long as we cannot accept the Leibnizian claim that this is certainly the best of all possible worlds, our search for better ones must certainly be the best of all possible searches. This means that models of world order must be derived from appropriate hypotheses and subjected to the strictures of systematic analysis. World order studies must be treated in accordance with the strict canons of inquiry outlined in this essay. Only then can they begin to develop the highly generalized system of theory that characterizes any science.  相似文献

This article considers in a different light the relationship between legal theory and ethics by means of an interpretation of the thought of Adorno and Horkheimer, and of the writings of Richard Rorty, as two moments of a marginal stream of ethics of passions that runs beneath the history of rationalist Western philosophy. It departs from the critique of Modernity as a dialectic of barbarism and civilisation, and from a genealogy of Auschwitz that finds its antecedents in Kantian morality. It also characterises modern culture as one of apathy and bourgeois stoicism, and establishes a link between the cold modern ethos and the dynamics of Nazi hardness. The article turns then to a consideration of some of the responses to the comprehensive crisis of Modernity: the imperative ‘Auschwitz never again’, Adorno’s ‘general enlightenment’ and Horkheimer’s ethics of sympathy. Finally it reflects upon Rorty’s proposal of sentimental education as an effective strategy to foster a human rights culture in Postmodernity, with the aim of bridging the tradition of moral sentiments and contemporary struggles for human rights. I am very grateful to Costas Douzinas, Sonia Romero, Shaun Haselhurst, David-Alexander Smith, José Bellido and the two anonymous referees for their comments, and to Alexander García-Düttman for his suggestions. This text is dedicated to Paul Gready.  相似文献

Studying dipterans at the scene of a death can provide essential information for interpreting the evidence and help to reconstruct the events happened to a corpse in the past. Molecular tools have been employed for identification at specific levels in the cases of cryptic species or poorly conserved specimens. Identification of specimens is essential in forensic entomology since each species has a specific growth rate, which determines the calculation of the minimum post mortem interval (minPMI). In addition, phylogeographic reconstruction within a species can help to differentiate the haplotypes from a geographic area, thereby helping to clarify the possible relocation of a corpse. The morphological identification of Sarcophagidae species is often difficult, especially for the females. This is an important Diptera family since some of its species are among the first to reach a corpse, especially in warm areas. In this study, we compared the sarcophagids found in human corpses in forensic cases in Alicante (southeast of Spain) with specimens collected from baited traps in the same area and surrounding provinces. In total, 189 specimens were collected, comprising 72 from forensic cases and 117 from baited traps. Molecular identification was conducted by sequencing the cox1 mitochondrial gene and analyzing the sequences using ABGD, GMYC, and BIN species delimitation methods. The median joining algorithm in the PopART program was used to construct phylogeographic networks. Eight species in the family Sarcophagidae were identified. The most widely collected species were Sarcophaga argyrostoma and Sarcophaga tibialis. The haplotype networks obtained for these species did not indicate a clear geographic distribution of haplotypes. The S. argyrostoma samples from Alcoy were clearly isolated. The results demonstrated that this method is useful for identifying Sarcophagidae samples in forensic investigations and it can be employed for minPMI estimation.  相似文献

There is an assumption in much of the electoral engineering literature that domestic episodes of electoral system choice occur in a vacuum, isolated from international influences. Yet this assumption remains largely untested, despite the comparative focus of much of that literature. This article focuses on part of this gap by considering two electoral mechanisms that seek to limit party system fragmentation under proportional representation – low district magnitudes and high electoral thresholds – and shows that the mechanisms have spread across many European countries during the post‐1945 period. Analyses reveal that national legislators are more likely to adopt one of these electoral mechanisms when a large number of peer countries have made similar choices within the last two or three years. This effect is robust to various model specifications and to the inclusion of multiple controls. The article also offers some qualitative evidence from case studies and parliamentary debates.  相似文献

This paper is a case study of Eastern European immigrant women's social inclusion in Portugal through civic participation. An analysis of interviews conducted with women leaders and members of two ethnic associations provides a unique insight into their migrant pathways as highly educated women and the ways in which these women are constructing their citizenship in new contexts in Northern Portugal. These women's accounts of their immigrant experience embrace both the public realm, in using their own education and their children's as a means of integration but also spill over into ‘non-public’ familial relationships at home in contradictory ways. These include the sometimes traditional, gender-defined division of labour within the associations and at home and the new ways that they negotiate their relative autonomies to escape forms of violence and subordination that they face as women and immigrants.  相似文献

The extraction of DNA from human skeletal remains applied to forensic, and evolutionary studies do not exclude risks, which are to be evaluated when working with unique specimens that could be damaged or even destroyed. In the present study were evaluated several nondestructive methods for recovering DNA instead of the most currently used pulverization method. Three different procedures to access inside the dental pieces (occlusal perforation, cervical perforation, and cervical cut) have been compared with the aim of recovering as many cell remains as possible to carry out a DNA extraction. Given the DNA quantitation results, a method was proposed that consists of a cervical cut to facilitate the access to the pulp cavity and a subsequent filing of the root canals down to the apex of the dental root. This methodology allows the recovery of both mitochondrial and nuclear DNA, with the minimum deterioration for the dental pieces.  相似文献

Research into maximizing the speed, precision, and reliability of estimating the postmortem interval (PMI) has been a recurring object of investigation and methodologies based on the vitreous humor (VH) have provided good results. However, contamination from causes not readily apparent, such as blood, can occur, and thus lead not only to an erroneous estimation of PMI, but also interfere with the correct identification of other substances in the VH. We have developed a flow cytometry method which quantifies blood contamination and is able to detect erythrocytes in 1:750,000 dilution of contaminated VH which affects the results of hypoxanthine. It is an improvement on the previous more complex mass spectrometry method, being faster, more sensitive, and readily available. As such, it could be proposed for the rapid screening of appropriate samples by detecting and eliminating blood contaminated samples from PMI estimation.  相似文献
