The Impact of Juvenile Court Judge Ethical Orientation on Decision Making

This exploratory study examines the ethical ideologies of a sample of 76 juvenile court judges attending a conference using an Ethical Position Questionnaire. Potential effects of ethical orientation on judicial decision making are identified and discussed. The findings indicate a relatively even distribution of judges across ethical ideologies. The connection between ethical ideology and the prevailing juvenile justice philosophy across jurisdictions, and the importance and complexity of judicial education and training in juvenile justice, are discussed.     

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.     

Investigation of hydrogen cyanide generation from the cyanoacrylate fuming process used for latent fingermark detection

Cyanoacrylate fuming is one of the most common techniques employed for the detection of latent fingermarks on non-porous surfaces such as plastic and glass. The technique is generally applied by exposing items of interest to the vapours generated by heating a suitable quantity of commercial cyanoacrylate adhesive. In this study, the potential for highly toxic hydrogen cyanide (HCN) to be generated from the overheating of cyanoacrylate was investigated. Two commercial cyanoacrylate adhesives and two quantitative methods for the determination of HCN were employed: (i) the sodium picrate method; and (ii) the picrate-resorcinol method. (13)C nuclear magnetic resonance (NMR) analysis was used to confirm the presence of cyanide. In addition, the thermal decomposition of cyanoacrylate was studied using simultaneous thermogravimetric and differential thermal analysis (TGA-DTA). It was determined that detectable and quantifiable amounts of HCN were generated from the thermal decomposition of cyanoacrylate monomer and polymer at temperatures as low as 200 °C. Using an optimised picrate-resorcinol method, it was shown that around 10 μg of HCN could be generated from the heating of 1g of cyanoacrylate monomer at 200 °C. For one of the adhesives tested, this increased to above 100 μg of HCN when 1g of cyanoacrylate monomer was heated at 280 °C. Recommendations are provided that, if followed, should ensure that the cyanoacrylate fuming process can be safely applied with minimal risk to the operator.     

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.     

The forensic investigation of propane gas asphyxiation

Two unusual suicides of a 19-year-old white man and a 47-year-old white man, involving propane inhalation and plastic bag suffocation, are described. The special characteristics of propane gas as an asphyxiant agent are discussed, as well as its effect on the human body. The discussion emphasizes the postmortem examination and the collection of samples for toxicologic analysis.     

Citizenship and Res Publica : The Emergence of Republican Rights

A fourth kind of citizens' rights--the republican rights--are being recognized and enforced in the last quarter of the twentieth century, after the civil, political, and social rights have been defined. Republican rights are the rights that every citizen has that the public patrimony, the res publica , is utilized on behalf of the public interest. While civil rights protect citizens against a powerful state, republican rights protect the state against powerful citizens involved in several forms of rent-seeking. Three major types of republican rights are identified: rights to the environment, to the historical patrimony, and to the economic patrimony. The last, in flow terms, corresponds to the state's revenues, which are permanently threatened by businessmen, bureaucrats, and all kinds of special interest groups, sometimes in subtle ways. To identify and contain these threats is a major challenge for modern institutions and law systems.
