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.     

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.     

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.     

The Performance of Nursery Schools in Italian Municipalities

In a neo-liberal approach, the need to increase levels of cost saving, effectiveness, and quality in producing local public services is correlated to awareness of the limited resources available and is an economic issue that has been much debated in recent decades. Ways of measuring and evaluating public services have stimulated academic interest for several years now. In this context, evaluating the levels of performance of public services provided by non-profit organizations (NPOs) as a consequence of contracting-out by public administration is an essential variable in rationalizing—both in terms of quantity and quality—public expenditure.

The aim of this article is to measure multi-dimensional aspects of nursery school services offered by Italian municipalities and to verify whether using different management models makes a difference in the results obtained. We examine data contained in final accounts of main Italian municipalities in order to evaluate effectiveness, cost saving, and quality aspects of the nursery school service supplied.

Regarding overall performance, the distinction between direct management and contracting-out has not brought out significant differences in terms of effectiveness and cost saving, even if the direct management solution is better than the externalized one. By contrast, as previous research showed, quality levels for externalized services are on average lower than for directly managed services.
