Cost-benefit Analysis of Infrastructure Projects in an Enlarged European Union: Returns and Incentives

We consider results of cost-benefit analysis (CBA) in a large sample of ISPA (Structural Instrument for Pre-Accession countries) projects co-financed by the European Union to support investment in transport and environment. The research focus is on the empirical analysis of the variability of financial and economic rates of return and how to integrate this information in the EU co-financing mechanism. We investigate to what extent the variability of expected returns and of EU co-financing rates is due to structural project characteristics (sectors, countries) or to other unexplained factors, including errors in the appraisal. We find that while the absolute level of grants is related to sectors, the EU co-financing rate depends on countries. There is no justification in economic analysis of such a country bias, because the variability of economic rate of returns is unrelated either to sector or country factors. These findings points to the need of a more consistent approach to evaluation and EU co-financing of infrastructure supported by the EU funds. We suggest possible improvements, based on the idea to offer an incentive to projects with high-expected economic␣rates of return relative to a benchmark and showing ex-post the realism of the initial analysis.      

Can you hear me Major Tom? News,narratives and contemporary military operations: the case of the Italian mission in Afghanistan

This research explores the relationship between public narratives and the Italian military contribution to the International Security Assistance Force (ISAF) in Afghanistan (2001–2014). Despite attracting little attention in the literature, Italy has been one of the most crucial contributors of multilateral military missions around the world in the post-bipolar era. Italy has remained consistently engaged militarily in Afghanistan over the entire period of the ISAF mission. However, the country’s involvement has been characterised by differing and controversial views and perspectives among Italian political actors and the media. This study aims to reconstruct the core features of the strategic narratives and the media frames around the military intervention and it does so through a Qualitative Content Analysis on a collection of almost 200 articles published by four main Italian national newspapers. The goal of this paper is twofold: on the one hand, we systematically retrace the main discursive patterns and frames employed by the newspapers on the ISAF. On the other, we evaluate whether in the case of military interventions, the Italian media unveil critical inconsistencies and competitive arguments or whether they function as a repeater of the dominant political discourse. Thanks to the case study, we find that the Italian media supported the mainstream narratives.     

Peer influences on the dating aggression process among Brazilian street youth: a brief report

This study explored risk factors for adolescent dating aggression (ADA) among Brazilian street youth. Forty-three adolescents, between the ages of 13 and 17 years, were recruited at services centers in Porto Alegre, Brazil. Simultaneous multiple regression revealed that ADA was significantly predicted by adolescent dating victimization (ADV), and that this relationship was moderated by peer involvement in dating aggression. Results also revealed that peer involvement in dating aggression did not significantly predict ADA. These findings suggested that having peers who are involved in dating aggression exacerbates the effects of dating victimization on ADA among Brazilian street youth. However, ADV might be a stronger risk factor for dating aggression in this population, because when controlling for the effects of victimization in dating conflicts peer abuse toward romantic partners did not uniquely contribute to ADA.     

Altered handwriting suggests cognitive impairment and may be relevant to posthumous evaluation

Judging the validity of a disputed will is complex; however, one of the main issues is what the mental status of the testator was at the time of the will. If the will is handwritten, a handwriting analysis can provide information on the mental status of the testator. We tested how two writing parameters (the "writing score," a novel evaluation scale that we previously described, and the percentage of spelling mistakes) are capable to identify cognitively impaired persons. These parameters are especially helpful because they can be used to evaluate the mental status of a deceased person. We found a significant correlation between either parameter and established scales of neuropsychological evaluation (Mini Mental State Examination and Milan Overall Dementia Assessment scale). Specifically, a poor score on either parameter reliably identified a compromised cognitive status. These may represent helpful additions to existing techniques in posthumously identifying persons with severe cognitive impairment.     

Results of the 2003-2004 GEP-ISFG collaborative study on mitochondrial DNA: focus on the mtDNA profile of a mixed semen-saliva stain

We report here a review of the seventh mitochondrial DNA (mtDNA) exercise undertaken by the Spanish and Portuguese working group (GEP) of the International Society for Forensic Genetics (ISFG) corresponding to the period 2003-2004. Five reference bloodstains from five donors (M1-M5), a mixed stain of saliva and semen (M6), and a hair sample (M7) were submitted to each participating laboratory for nuclear DNA (nDNA; autosomal STR and Y-STR) and mtDNA analysis. Laboratories were asked to investigate the contributors of samples M6 and M7 among the reference donors (M1-M5). A total of 34 laboratories reported total or partial mtDNA sequence data from both, the reference bloodstains (M1-M5) and the hair sample (M7) concluding a match between mtDNA profiles of M5 and M7. Autosomal STR and Y-STR profiling was the preferred strategy to investigate the contributors of the semen/saliva mixture (M6). Nuclear DNA profiles were consistent with a mixture of saliva from the donor (female) of M4 and semen from donor M5, being the semen (XY) profile the dominant component of the mixture. Strikingly, and in contradiction to the nuclear DNA analysis, mtDNA sequencing results yield a more simple result: only the saliva contribution (M4) was detected, either after preferential lysis or after complete DNA digestion. Some labs provided with several explanations for this finding and carried out additional experiments to explain this apparent contradictory result. The results pointed to the existence of different relative amounts of nuclear and mtDNAs in saliva and semen. We conclude that this circumstance could strongly influence the interpretation of the mtDNA evidence in unbalanced mixtures and in consequence lead to false exclusions. During the GEP-ISFG annual conference a validation study was planned to progress in the interpretation of mtDNA from different mixtures.     

Minor or adult? Introducing decision analysis in forensic age estimation

Nowadays, forensic age estimation takes an important role in worldwide forensic and medico-legal institutes that are solicited by judicial or administrative authorities for providing an expert report on the age of individuals. The authorities’ ultimate issue of interest is often the probability that the person is younger or older than a given age threshold, which is usually the age of majority. Such information is fundamental for deciding whether a person being judged falls under the legal category of an adult. This is a decision that may have important consequences for the individual, depending on the legal framework in which the decision is made. The aim of this paper is to introduce a normative approach for assisting the authority in the decision-making process given knowledge from available findings reported by means of probabilities. The normative approach proposed here has been acknowledged in the forensic framework, and represents a promising structure for reasoning that can support the decision-making process in forensic age estimation. The paper introduces the fundamental elements of decision theory applied to the specific case of age estimation, and provides some examples to illustrate its practical application.
