DXAGE: A New Method for Age at Death Estimation Based on Femoral Bone Mineral Density and Artificial Neural Networks

Age at death estimation in adult skeletons is hampered, among others, by the unremarkable correlation of bone estimators with chronological age, implementation of inappropriate statistical techniques, observer error, and skeletal incompleteness or destruction. Therefore, it is beneficial to consider alternative methods to assess age at death in adult skeletons. The decrease in bone mineral density with age was explored to generate a method to assess age at death in human remains. A connectionist computational approach, artificial neural networks, was employed to model femur densitometry data gathered in 100 female individuals from the Coimbra Identified Skeletal Collection. Bone mineral density declines consistently with age and the method performs appropriately, with mean absolute differences between known and predicted age ranging from 9.19 to 13.49 years. The proposed method—DXAGE—was implemented online to streamline age estimation. This preliminary study highlights the value of densitometry to assess age at death in human remains.     

Child Suicide in the North of Portugal

Suicide in children is a rare finding and is probably motivated by acts of impulsiveness. This study aims to contribute to the characterization of child suicide in a forensic perspective in the Portuguese population. Data of forensic autopsies from 2004 to 2012 related to suicide victims under 18 years were reviewed. A total of 17 cases, with a male predominance (64.7%) and a mean age of 15.24 ± 1.348 for both genders, were registered. The leading suicide method was hanging (35.3%), and a suicide note was found in 41.2%. Psychological autopsy proved to be useful in promoting a better understanding of these incidents and their antecedents. This study also offers useful information, namely the implied risk factors, for future programs of suicide research and prevention.     

Knowledge flows,the influence of national R&D structure and the moderating role of public–private cooperation

This paper analyses country-specific determinants of knowledge flows with a view to uncover the role of cross-organizational interactions. Using a sample of some 600,000 patents from the EU27 member states in the period 1990–2007, we take backward citations as dependent variable and find that technological sophistication and research size have a positive effect on knowledge flows. While a national bias towards applied research and development has a negative impact, individual public–private cooperation has a moderating effect due to the generation of scientific knowledge by public institutions. The present study contributes to the debate concerning the direction of R&D investments and provides empirical support to policies aimed at the enhancement of public–private cooperation.     

The Rhetorical Syllogism (Enthymeme) in Judicial Argumentation

The thesis here expounded can be divided in three parts: in the first place, it is supposed that the syllogism is not the rhetorical way, and less still the logical way, indeed used to reach the decision in the legal proceedings monopolized by the modern State. At the most, it can be seen as a form of presenting a decision that has already been reached by other means. It sure constitutes a highly functional procedure, effective and legitimating. It is generally not a conscious strategy on the part of the so called official legal agents (judges, prosecutors, state attorneys, lawyers, plaintiffs), which seem to believe that the decision before the concrete case is in fact produced by the previous general norm enunciated by the system. If there would be a chronological order, the general norm comes afterwards. In the second place, the judicial discursive structure seems to be rather enthymematic than syllogistic, because not all the effectively used norms are revealed, many of them staying not only out of question but also hidden. Finally, it is suggested that, in the atmosphere of faking dogmatic law in which acts the underdeveloped State, those implicit norms are not just presupposed as evident, but they are also uncertain, being rendered to manipulation.
