One Hundred and One Cases of Plastic Bag Suffocation in the Milan Area Between 1993 and 2013—Correlations,Circumstances, Pathological and Forensic Evidences and Literature Review

Plastic Bag Suffocation is a rare cause of death in developed countries and almost unknown in the rest of the world. This study aims to retrospectively evaluate cases of PBS _asphyxia in Milan's Department of Legal Medicine from 1993 to 2013. Cases were selected from the database of 21,472 autopsies performed in the considered timeframe. One hundred and one cases were considered to be cases of Plastic Bag Suffocation, comprised of 100 suicides, no accidental events and 1 homicide. The most relevant elements pertaining to this type of death were evaluated for both the corpses and the crime scenes. From this study the typical PBS victim is an adult male, aged 52.3 years on average, depressed or afflicted by chronic or terminal diseases, and found at home. In 42.6% of cases, the victims were found with the plastic bag still positioned over their head, fastened by tying. Also common among these cases are drugs, alcohol and chemical abuses. According to the collected data, it is impossible to outline a pathognomonic detrimental background that leads to this cause of death. Crime scene investigation is, therefore, the one and only technical resource for evaluating these cases.     

In need of a cultural shift to promote restorative justice in Southern Europe

The article describes the main results of a European project on restorative justice (RJ) called Freedom Wings (FW) and presents a new model to promote RJ in Southern Europe, which was developed from FW findings. The principal mission of the FW project is to disseminate best practices of RJ within a transnational network and to promote community participation in conflict prevention and resolution, in order to support individual and social well-being. This paper presents the main findings of multiagency and professional focus groups exploring restorative approaches and community justice. Observation of experts’ social representation of RJ helped the authors to understand the operation of the justice systems in each country and the attitudes of senior officials towards implementing restorative practices in a way that actively involves the community. The analysis shows the necessity of a cultural change in order to switch from a form of RJ managed by the judicial system to one led by the community. The EU project enabled the research team to theorize a model for promoting a relational and restorative community.     

Fingerprint Change: Not Visible,But Tangible

Hand–foot syndrome, a chemotherapy‐induced cutaneous toxicity, can cause an alteration in fingerprints causing a setback for cancer patients due to the occurrence of false rejections. A colon cancer patient was fingerprinted after not having been able to use fingerprint recognition devices after 6 months of adjuvant chemotherapy. The fingerprint images were digitally processed to improve fingerprint definition without altering the papillary design. No evidence of skin toxicity was present. Two months later, the situation returned to normal. The fingerprint evaluation conducted on 15 identification points highlighted the quantitative and qualitative fingerprint alteration details detected after the end of chemotherapy and 2 months later. Fingerprint alteration during chemotherapy has been reported, but to our knowledge, this particular case is the first ever reported without evident clinical signs. Alternative fingerprint identification methods as well as improved biometric identification systems are needed in case of unexpected situations.     

The empty place of European power: Contested democracy and the technocratic threat

In this article, I analyse the European Union (EU) in the light of the Lefortian question: What place does power have in a democracy? Claude Lefort has argued that modern democracy is a regime where the place of power is empty. In this article, I investigate what this entails for the EU. I take the current situation of democracy in the EU as being marked by two developments: the contestation of democracy by citizens on the one hand and the hollowing out of democracy at the EU level on the other. Exemplary for the first development are the popular protest movements known as the indignados. The second feature is exemplified by governance and technocracy. My argument suggests that the critical response of the former to the latter can in fact be read as the claim that what should have been the empty place of power in European democracy has come to be occupied by the establishment of an authoritarian regime of expert rule.     

Age estimation by pulp/tooth ratio in canines by peri-apical X-rays

Estimation of age in individuals has received considerable attention in forensic science, in which it is a widely used method for individual identification, together with paleo-demographic analyses to establish mortality patterns in past populations. The present investigation, which is a continuation of a previously published pilot study, was conducted to examine the possible application of the pulp/tooth area ratio by peri-apical images as an indicator of age at death. A total of 200 peri-apical X-rays of upper and lower canines were assembled from 57 male and 43 female skeletons of Caucasian origin, aged between 20 and 79 years. They belong to the Frassetto osteological collection of Sassari (Sardinia) and are housed in the Museum of Anthropology, Department of Experimental and Evolutionistic Biology, University of Bologna. For each skeleton, dental maturity was evaluated by measuring the pulp/tooth area ratio on upper (x(1)) and lower (x(2)) canines. Very good agreement was found between intraobserver measurements. Statistical analysis was performed in order to obtain multiple regression formulae for dental age calculation, with chronological age as dependent variable, and gender, and upper and lower canines as independent variables. Stepwise regression analysis showed that gender did not contribute significantly to the fit (p=0.881) whereas variables x(1) and x(2) and the first-order interaction between them did. These two variables explained 92.5% of variations in estimated chronological age and the residual standard error was 4.06 years. Lastly, two simple linear regression equations were obtained for age estimation using canines from the maxilla and mandible separately. Both models explained 86% of variations in estimated chronological age and allowed an age-at-death estimate with a residual standard error of about 5.4 years.     

Age estimation by pulp/tooth ratio in canines by mesial and vestibular peri-apical X-rays

Changes in the size of the pulp canal, caused by apposition of secondary dentine, are the best morphometric parameters for estimating age by X-rays. The apposition of secondary dentine is the most frequently used method for age estimation in adult subjects. In two previous papers, we studied the application of the pulp/tooth area ratio by peri-apical X-rays as an indicator of age at death. The aim of the present study was to test the accuracy of age evaluation by combined analysis of labio-lingual and mesial peri-apical X-rays of lower and upper canines. A total of 200 such X-rays were assembled from 57 male and 43 female skeletons of Caucasian origin, aged between 20 and 79 years. For each skeleton, dental maturity was evaluated by measuring the pulp/tooth area ratio according to labio-lingual and mesial X-rays on upper (x(1), x(2)) and lower (x(3), x(4)) canines. Very good agreement was found between intra-observer measurements. Statistical analysis showed that all variables x(1), x(2), x(3), and x(4) and the first-order interaction between x(1) and x(3) contributed significantly to the fit, so that they were included in the regression model, yielding the following regression formula: Age = 120.737 - 337.112x(1) - 79.709x(2) - 364.534x(3) - 65.655x(4) + 1531.918x(1)x(3) . The residual standard error of estimated ages was 3.62 years, with 94 degrees of freedom, and the median of the residuals was -0.155 years, with an interquartile range of 4.96 years. The accuracy of the method was ME = 2.8 years, where ME is the mean prediction error. The model also explained 94% of total variance (R(2) = 0.94).     

Economic opening and society endogamy: migratory and reproduction logic in the Insubric mountains (18th and 19th centuries)

This article illustrates the character of the alpine and prealpine societies of the Insubric area, which is both open and closed. In these mountains, various migratory forms (periodic, temporary, and definitive) could be both exclusion and stability factors. Even if under a lineage model, family reproduction forms were close to a “unilineal” system. Yet, emigration left open pluriestablishement, the intensity of which depended on the openness of the local economy and demographic configuration of the households.     

Geographic and technological R&;D spillovers within the triad: micro evidence from US patents

This paper aims at assessing the magnitude of R&D spillover effects on large international R&D companies’ productivity growth. In particular, we investigate the extent to which R&D spillover effects are intensified by both geographic and technological proximities between spillover generating and receiving firms. We also control for the firm’s ability to identify, assimilate and absorb the external knowledge stock. The results estimated by means of panel data econometric methods (system GMM) indicate a positive and significant impact of both types of R&D spillovers and of absorptive capacity on productivity performance.
