The Pirates' Curse: Economic Impacts of the Maritime Piracy

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.     

DNA typing: an accessory evidence in doping control

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.     

Bite mark or bottle top?

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.     

Platforms, media and voters

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.     

Transaction Costs,Information Technologies,and the Choice of Marketplace among Farmers in Northern Ghana

Abstract

Using a transactions costs framework, we examine the impact of information and communication technologies (mobile phones and radios) use on market participation in developing country agricultural markets using a novel transaction-level data set of Ghanaian farmers. Our analysis of the choice of markets by farmers suggests that market information from a broader range of markets may not always induce farmers to sell in more distant markets; instead farmers may use broader market information to enhance their bargaining power in closer markets. Finally, we find weak evidence on the impact of using mobile phones in attracting farm gate buyers.
