Transplantation of organs and tissues and some reflections on the "solidarity" of the human cadaver in Portugal

The article presents the legal situation of transplantation medicine in Portugal and presents some interesting statistical data. The author defends the opting-out system and presents an argument in favour of such solution, taking into account the mandatory nature of forensic autopsies.     

Tests of one Brazilian facial reconstruction method using three soft tissue depth sets and familiar assessors

Facial reconstruction is a method that seeks to recreate a person's facial appearance from his/her skull. This technique can be the last resource used in a forensic investigation, when identification techniques such as DNA analysis, dental records, fingerprints and radiographic comparison cannot be used to identify a body or skeletal remains. To perform facial reconstruction, the data of facial soft tissue thickness are necessary. Scientific literature has described differences in the thickness of facial soft tissue between ethnic groups. There are different databases of soft tissue thickness published in the scientific literature. There are no literature records of facial reconstruction works carried out with data of soft tissues obtained from samples of Brazilian subjects. There are also no reports of digital forensic facial reconstruction performed in Brazil. There are two databases of soft tissue thickness published for the Brazilian population: one obtained from measurements performed in fresh cadavers (fresh cadavers' pattern), and another from measurements using magnetic resonance imaging (Magnetic Resonance pattern). This study aims to perform three different characterized digital forensic facial reconstructions (with hair, eyelashes and eyebrows) of a Brazilian subject (based on an international pattern and two Brazilian patterns for soft facial tissue thickness), and evaluate the digital forensic facial reconstructions comparing them to photos of the individual and other nine subjects. The DICOM data of the Computed Tomography (CT) donated by a volunteer were converted into stereolitography (STL) files and used for the creation of the digital facial reconstructions. Once the three reconstructions were performed, they were compared to photographs of the subject who had the face reconstructed and nine other subjects. Thirty examiners participated in this recognition process. The target subject was recognized by 26.67% of the examiners in the reconstruction performed with the Brazilian Magnetic Resonance Pattern, 23.33% in the reconstruction performed with the Brazilian Fresh Cadavers Pattern and 20.00% in the reconstruction performed with the International Pattern, in which the target-subject was the most recognized subject in the first two patterns. The rate of correct recognitions of the target subject indicate that the digital forensic facial reconstruction, conducted with parameters used in this study, may be a useful tool.     

Political Institutions,Policymaking, and Policy Stability in Latin America

In some Latin American nations, policy change occurs frequently, while in others it is stable, less prone to shifts with the prevailing political climate or shocks. The conditions under which institutional rules and the powers of key actors influence the capacity for governance vary, and this variation is seldom addressed in the literature. This project examines the effects of the interactions between key policymakers (the executive and the legislature) in Latin America on policy stability across different institutional frameworks. Countries with simultaneously strong executives and weak legislatures are shown to have unstable policy environments, as are countries with a history of unified government and, to a lesser extent, candidate‐centered electoral systems.     

Standardisation of nomenclature for dog mtDNA D-loop: a prerequisite for launching a Canis familiaris database

Domestic dogs are increasingly involved, often as protagonists, in the forensic scene. Acknowledging this fact and benefiting from the accumulated experience on human mitochondrial DNA (mtDNA) analyses, we propose a standard for Canis familiaris mtDNA sequences as a prerequisite for the launching of the corresponding database.

Parliamentary Questions as an Instrument for Geographic Representation: The Hard Case of Portugal

This article asks whether and why, in a system lacking electoral incentives to cultivate personal votes, MPs might choose to signal to geographic constituents. It explores this question by analysing the number of written parliamentary questions submitted to the Portuguese parliament on two issues – unemployment and crime – between 2009 and 2015, and asking if MPs are more inclined to table questions on specific issues when their districts suffer particularly from related problems. The article finds evidence that constituency‐level problem pressure does matter for the signalling activities of MPs, although policy specialization remains the main driver of their issue emphasis. This finding contributes new knowledge to the ongoing debate on the factors accounting for the representative relationship between MPs and constituents, by drawing attention to the importance of district‐level problem pressure as one of the drivers of issue sponsorship in parliament.     

Perceptions and personal experiences of unwanted attention among Portuguese male students

The present study investigated male perceptions and personal experiences of ‘unwanted attention’ (UA), as well as possible associations between perceptions and personal experiences of UA. Ninety-one male college students, from five Portuguese universities, were asked to indicate which of a continuum of 47 behaviours represented UA. Although UA, stalking and harassment are rarely addressed in Portugal, male college students shared a clear understanding of what behaviours constituted UA, with the identification of four main categories of UA behaviours: ‘aggressive’, ‘threatening’, ‘classic’ and ‘dysfunctional attachment’. Almost all participants (96%) reported personal experiences of at least one UA behaviour. There was a minimal relationship between perceptions and personal experiences of the individual behaviours. The findings highlight the widespread risk of male victimisation and the need to legitimise male complaints.     

Evaluation of the composition of street cocaine seized in two regions of Brazil

This work evaluates cocaine purity and the concentration ranges of adulterants and inorganic constituents for 31 street cocaine samples seized in two different regions of Brazil from July 2008 to May 2010. Cocaine and adulterants, such as caffeine, lidocaine and benzocaine, were quantified by Gas chromatography–mass spectrometry (GC–MS), and the inorganic constituents were determined by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and ion chromatography (IC). The cocaine concentrations in the samples seized in the Amazonas state (AM samples) ranged from 154 to 978 mg g^? 1, and these samples did not contain any of the adulterants studied. The cocaine concentrations in the samples seized in the Minas Gerais state (MG samples) ranged from 63.9 to 753 mg g^? 1. Caffeine was the main adulterant found in 76% of the MG samples, ranging in concentration from 5.5 to 645.3 mg g^? 1. Lidocaine was found in 66.7% of the MG samples, with concentrations ranging from 16.3 to 576.7 mg g^? 1. Benzocaine was found in only one MG sample, at a concentration of 84.8 mg g^? 1. Fourteen elements were identified by ICP-OES, and a wide variation was observed in the concentrations of Ca, Mg, Na, P, Al, Fe, Mn and Zn. Pearson Product–moment Correlations between the analytes allowed the constituents to be associated with the chemicals used in the manufacturing of cocaine and with some common diluents. The study of the purity of cocaine and the presence and concentration of adulterants and inorganic constituents is important because the latter can have deleterious effects on health.     

Child-to-Parent Violence in Adolescents: The Perspectives of the Parents,Children, and Professionals in a Sample of Spanish Focus Group Participants

This study explored the characteristics of child-to-parent violence (CPV) in Spain based on the narrations of adolescents who perpetrate this kind of violence, their parents, and the professionals who work in this area. A qualitative design was used. Focus groups were asked about the risk factors associated with CPV, such as exposure to family violence, discipline, and psychological characteristics of the adolescents. Interviews were videotaped, transcribed, and reviewed independently by each investigator to identify and group distinct comments into categories with specific themes. Results suggest that CPV is mainly linked to exposure to marital conflict and family violence, permissive discipline, emotional disengagement in the father-child relationship, and symptoms of emotional stress and substance consumption in the children. Lastly, acts of CPV seem to be an attempt by the children to gain power in the context of family relations in which the parents display their incapacity to establish control. As several family and personal characteristics appear to be involved in CPV, it is recommended that family and individual approaches be considered for treatment.
