This article reviews the December 2007 United Nations Climate Change Conference in Bali. It considers expectations for the meeting and whether the event delivered on these expectations. It also evaluates the long-term context of the meeting and examines the discussions in Bali on the post-2012 period (when the Kyoto Protocol's first 'commitment period' expires). The article finds that the Bali meeting did not necessarily meet public expectations or respond directly to the latest scientific assessments calling for urgent action. However, the article also finds that Bali was successful in the context of the prevailing political and diplomatic realities and the immense complexity of the climate change challenge – a problem that does not lend itself to a 'quick fix' solution. The article concludes that Bali produced a solid outcome that gives direction to future talks and sets a clear deadline for their completion. Finally, it argues that, contrary to some experts' opinion, the lack of detail in the Bali outcome may prove to be a strength rather than a weakness, since it provides flexibility to negotiators as they try to craft a consensus by the end of 2009. 相似文献

Governance in the developing world is fraught with problems of corruption, weak institutions, and inadequate expertise among bureaucrats. Failing to enforce laws and regulations is one way in which these problems manifest themselves. In this paper, we evaluate changes across three institutions charged with oversight or administration of labor justice in Mexico. We find that both autonomy from the executive and professionalization are necessary to improve compliance with labor law over time. Our study shows that professionalization can occur in several ways, including through training, merit hiring, and introducing experienced external administrators. The implications of the study are that reforms that increase the independence and legal authority of oversight institutions should be complemented by efforts to strengthen the professionalism of bureaucrats. 相似文献

Many structural relationships should be taken into account in any reasonable adjustment and updating process. These structural relationships are mainly represented by ratios of different types, such as technical coefficients or the proportion of the cell value in relation to its row or column total. We believe that in many cases (either because of lack of information or when the time elapsed for the estimation of a social accounting matrix is not long enough to allow for any significant structural change) the updating process should try to minimize the rela- tive deviation of the new coefficients from the initial ones in a homogeneous way. This homogeneity would mean that the magnitude of this relative deviation is similar among the elements of each row or column, therefore avoiding the concentration of the changes in particular cells of the SAM. In this work, we propose some new adjustment criteria in order to obtain a more homogeneous relative adjustment of the structural coefficients. These criteria combine the adjustment method proposed by Matuszewski et al. (1964) with other deviation functions. Each of the adjustment criteria proposed leads to a nonlinear optimization problem which is reformulated as a linear program. We test the usefulness of this proposal by comparing its results with the ones obtained by more standard approaches and we are able to show that these approaches tend to produce a less homogeneous pattern of coefficient adjustment, under certain circumstances, than the ones we put forward. 相似文献

The true impact of heat-induced changes in human bone regarding their sex estimation has not been comprehensively documented having a potentially negative impact on forensic anthropology. The objective of this paper was to evaluate how heat exposure affects sex estimation based on both morphological and metric features. The study focused in both low-to-medium intensity burns and high intensity burns. Selected sexually dimorphic features were analysed in 51 experimentally burnt skeletons from the 21st Century Identified Skeletal Collection. Bones were burnt to maximum temperatures between 450 °C and 1050 °C achieved after 75 to 257 min. Morphological methods tested in this study comprised the recommendations for hipbone features from Buikstra and Ubelaker (1994) and from Bruzek (2002). On the other hand, metric references tested here were the ones from Wasterlain (2000), Curate et al. (2016) and Gonçalves et al. (2013) focused on the humerus, femur, calcaneus and talus. Agreement was tested with Gwet’s AC1 test and was further assessed by calculating the relative amount of perfect agreements. Results demonstrated that heat-induced changes affected not only the scoring of morphological features burnt at high temperatures but also the scoring of features burnt at lower intensities. On the other hand, metric features were only considerably affected in high intensity burns, no major changes being documented for low-to-medium intensity burns. For low-to-medium intensity burns, the Bruzek and Curate et al. methods revealed a better agreement between the pre- and post-burning scores. For high intensity burns, better agreement was obtained by using the Bruzek (2002) and Gonçalves et al. (2013) methods. As expected, heat-induced warping, fracture and metric change had a major impact on the pre- and post-observations’ agreement. Contrary to what has been systematically assumed over the years, this impact is also quite substantial in bones burnt at low-to-medium burn intensities so caution is advised during the analysis of this kind of burnt skeletal material. 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

National Identity or National Interest? Scottish,English and Welsh Attitudes to the Constitutional Debate 下载免费PDF全文
This article analyses political attitudes to the union in England, Scotland and Wales after the Scottish independence referendum. Using public opinion data, we explore constitutional preferences and perceptions of national grievance, before examining the role that national identity plays in structuring preferences. Our evidence shows that considerable demand exists for nationally demarcated forms of government within the UK, although these constitutional preferences do not translate in support for policy diversity across the UK. We also find evidence that these constitutional preferences relate closely to national identity, but relate also to appeals to national interest. 相似文献

This study analyses the extent, sense, and strategies employed by sympathisers with Spanish state-wide left-wing parties to ‘reconstruct’ their affective ties with the Spanish nation after the ‘monopolisation of patriotism’ by Franco's regime. Such an undertaking is further complicated within the context of economic crisis and intensified peripheral nationalism found in Catalonia and the Basque Country. This article applies qualitative analysis to the discourse of left-wing participants from 11 focus groups held in March 2012 amidst the economic (and political) crisis. As expected, this context of crisis favoured the emergence of explicit discourse on the Spanish nation, providing an opportunity to gain a better understanding of its nature. Findings show that welfare nationalism and social patriotism define the kind of attachment developed by the interviewees towards Spain better than the concept of constitutional patriotism, or any kind of ethnic-cultural feeling of belonging. 相似文献

Relations between the European Union (EU) and regional subgroups in Latin America (Mercosur, the Andean Community and Central America) are clear examples of ‘pure interregionalism’ and provide evidence of the EU's active promotion of regional integration. Within the context of these cases, this article explores what type of international power the EU wields, how interregionalism is embedded in that power, and how it is deployed. Combining strands of literature on EU–Latin American relations, interregionalism, EU external policy and power provides a framework within which interregionalism can be understood as an important normative and practical tool for the EU's external power projection. Drawing on official documentation and interviews with key individuals, the paper highlights the EU's articulation of power in interregional relations and reflects upon its mixed success. It concludes that, while imperial qualities and aspirations can be observed in the EU's penchant for interregionalism, the transformative power of the EU remains limited. 相似文献
