During the last decades, the activities of pirates have increased exponentially in Eastern Africa, with their attacks becoming considerably more violent. In addition to the intrastate and interstate conflicts, the lack of state capacity and the presence of terrorist groups, maritime piracy represents a serious and sustained threat to economic security. Indeed, from an economic point of view, pirates affect international trade through an increasing insecurity related to the prompt delivery of the goods transported. The aim of this work is to explore the main works on maritime piracy analyzed in quantitative economics.  相似文献

A clear positive case for anabolic steroids doping was confounded by alleged urine tampering during doping control procedures. Review of the chain of custody showed no flaws, but nevertheless the athlete was adamant that the urine sample should be analyzed for DNA in order to support her contention that she was not the donor of the sample. The results obtained showed that the urine sample that scored positive for steroids contained nuclear DNA that could not be matched to the DNA obtained from the athlete's blood. On the other hand, the same urine sample contained mitochondrial DNA whose nucleotide sequences spanning the hyper variable regions HV1 and HV2 proved to be identical to those determined in mitochondrial DNA amplified from the athlete's blood. The occurrence of an extraneous genotype is compatible with exogenous nuclear DNA admixture to the athlete's urine. Alternatively, taking in consideration the mitochondrial DNA, we could not exclude that a sibling or a maternal relative of the athlete could have acted as a donor of the urine utilized for doping control and DNA analysis. Both situations point to possible tampering of the urine by the athlete. Adjudication at CAS maintained previous national and international federation decision that there was no proof of a chain of custody flaw to justify the athlete's allegation of urine substitution after collection.  相似文献

An alleged assault was reported by a 42-year-old female, with initial medical examination revealing an apparent bite mark on the right buttock. Odontological examination, including visual assessment, full history and photographs showed that the injury did not meet the class characteristics of a human bite. Subsequent digital overlay production showed that the injury pattern was consistent with a corrugated bottle top. This case highlights the need for careful assessment of injuries alleged to be caused by human teeth.  相似文献

The paper presents data on party platforms, political communication and public opinion in the 1996 Italian election campaign. It is shown that the electoral platforms of the two major coalitions were largely overlapping, except for some economic and social issues. The centre–right coalition seemed more inclined to adopt pro–market policies, while the platform of the Ulivo coalition was more oriented toward a social partnership approach. In the month before the elections, policy issues were discussed on television more extensively than political issues. Public and private networks covered the 1996 election campaign at the same level as in 1994 and to some extent with the same bias. Voting intentions seem to have remained stable prior to and during the electoral campaign.  相似文献

Political ecologists have developed scathing analyses of capitalism’s tendency for enclosure and dispossession of the commons. In this context commons are analyzed as a force to resist neo-liberalism, a main site of conflict over dispossession, and a source of alternatives to capitalism. In this paper we elaborate a view of the commons as the material and symbolic terrain where performative re-articulation of common(s) senses can potentially enact counter-hegemonic socio-ecological configurations. Expressly drawing on the concepts of hegemony, “common-senses” (inspired by Antonio Gramsci) and “performativity” (developed by Judith Butler), we argue that counter-hegemony is performed through everyday practices that rearticulate existing common senses about commons. Commoning is a set of processes/relations enacted to challenge capitalist hegemony and build more just/sustainable societies insofar as it transforms and rearranges common senses in/through praxis. The paper draws on the experience of an anti-mining movement of Casa Pueblo in Puerto Rico, which for the last 35+ years has been developing a project self-described as autogestion. The discussion pays special attention to Casa Pueblo’s praxis and discourses to investigate how they rearticulate common senses with regard to nature, community and democracy, as well as their implications for counter-hegemonic politics.  相似文献
