Inhabiting Mourning: Spectral Figures in Cases of Extrajudicial Executions (False Positives) in Colombia

In this article we analyse various forms of emotional management of mourning in the experiences of six female relatives of victims of extrajudicial executions in Colombia. Referencing the concept of the ‘spectral’, we discuss the ways in which family members establish ways of living with mourning that emphasise the impossibility of achieving closure, and explore the ways in which they keep the wounds of their suffering open as a means of organising themselves politically, in pursuit of justice. The article suggests an alternative to a teleology of closure, suggesting that, in contexts of impunity such as the one prevailing in Colombia, mourning becomes a scenario of habitability.     

Electoral reforms,entry barriers and the structure of political markets: A comparative analysis

This article investigates the impact of electoral reforms on entry barriers in political markets. The discussion starts by delineating the theoretical boundaries of various political markets, such as those for participation, parties and government. By taking a cue from industrial organisation theory, the article offers an analysis of entry barriers, both hard and soft, along with their operationalisation for empirical research. Based on this theoretical framework, a single hypothesis is investigated. It posits that the modification of the entry barriers in the market for parties leads to changes in the concentration of the popular vote for party lists. An observable implication of this relationship would be if an electoral reform that raises entry barriers led to subsequent increases in the Herfindahl index (a measure of market concentration), and vice versa. This proposition is empirically tested by a comparative analysis of a new database covering Czechia, Hungary, Poland and Slovakia. The analysis offers support for the following proposition: in most cases the changes in the entry barriers led to a corresponding change of concentration in the market for parties.     

The Attachment of Demonstrators to Institutional Politics: Comparing LGBTIQ Pride Marches in Argentina and Chile

Focusing on LGBTIQ demonstrations in Argentina and Chile, we study protesters' attachment to institutional politics, defined as their emotional and attitudinal connection with the political system. We show that Argentine LGBTIQ demonstrators are on average more attached to institutional politics than Chilean ones. This can be explained neither by differences between Argentines and Chileans in general, nor by demonstrators' individual characteristics. Instead, expanding the political process model, we argue that achieving a substantial part of the LGBTIQ agenda in Argentina, and limited success in Chile, contributed to build a stronger attachment to the political system among Argentine LGBTIQ demonstrators than their Chilean counterparts.     

Mineralization of mandibular third molars can estimate chronological age--Brazilian indices

Forensic age estimation is an important element of anthropological research, as it produces one of the primary sources of data that researchers use to establish the identity of a person living or the identity of unknown bodily remains. The aim of this study was to determine if the chronology of third molar mineralization could be an accurate indicator of estimated age in a sample Brazilian population. If so, mineralization could determine the probability of an individual being 18 years or older. The study evaluated 407 panoramic radiographs of males and females from the past 5 years in order to assess the mineralization status of the mandibular third molars. The evaluation was carried out using an adaptation of Demirjian's system. The results indicated a strong correlation between chronological age and the mineralization of the mandibular third molars. The results indicated that modern Brazilian generation tends to demonstrate an earlier mandibular third molar mineralization than older Brazilian generation and people of other nationalities. Males reached developmental stages slightly earlier than females, but statistically significant differences between the sex were not found. The probability that an individual with third molar mineralization stage H had reached an age of 18 years or older was 96.8-98.6% for males and females, respectively.     

Experimental forensic scenes for the characterization of ground-penetrating radar wave response

Over the last few decades, the use of non-intrusive geophysical techniques, which allows for coverage of an entire crime scene in a reasonable amount of time, in forensic investigation has increased. In this study, we analyze the effectiveness of ground-penetrating radar (GPR) in forensics. Experimental scenes were simulated and some of the most commonly buried items in actual crime scenes were introduced, such as bone remains, guns and drug caches. Later, a GPR survey was conducted on the experimental grids with a 500 MHz antenna. The final purpose was to characterize the radar wave response expected for each set of remains to assist with its identification in later actual investigations. The results collected provided promising information that can be used when surveying real cases. Nevertheless, there were some interpretational difficulties regarding the sizes of the items and the electromagnetic properties of the materials. For these cases, finite-difference time-domain modeling was employed to achieve an advanced interpretation of the field data. The simulated models used were built from accurate geometric data provided by photogrammetric methods, which replicate the experimental scenes in fine detail. Furthermore, this approach allowed for the simulation of more realistic models, and the synthetic data obtained provided valuable information for assisting in the interpretation of field data. As a result of this work, it was concluded that GPR can be an effective tool when searching for a variety of materials during a crime scene investigation.     

Freedom of Opinion and Freedom of Expression: Some Reflections on General Comment No. 34 of the Un Human Rights Committee

The United Nations Human Rights Committee is a body of 18 independent experts (including a member from the Netherlands, Professor Cees Flinterman) who are tasked with monitoring compliance with the provisions of the 1966 International Covenant on Civil and Political Rights (in force 23 March 1976). The Committee deploys four principal activities — periodic examination of State Party reports, interpretation and progressive development of the provisions of the Covenant in the form of General Comments, and adjudication of individual complaints under the Optional Protocol, as well as follow-up procedures. This article analyzes the Committee’s second General Comment on Article 19 of the Covenant, which stipulates freedom of opinion and freedom of expression. In 52 paragraphs the General Comment systematically examines, defines and delimits the concepts contained in the three subparagraphs of Article 19, basing itself primarily on the Committee’s concluding observations upon examination of State Party reports and on the case-law in response to petitions under the Optional Protocol. The Committee highlights the primacy of freedom of opinion, recognizing that it is crucial for a democratic society that persons have access to truthful, reliable and pluralistic information, including through the internet, in order to develop a personal opinion whose expression must then be protected by law. The Committee notes, however, that whereas it is inadmissible to impose any restrictions on freedom of opinion, there are certain responsibilities that attach to the exercise of freedom of expression, namely the respect of the reputation of others as well as considerations of health, morals and national security. The Committee holds that so-called ‘memory laws’ as well as blasphemy laws are incompatible with Article 19 and that defamation laws must strike a balance between competing rights and interests. Paragraph 49 of the General Comment clearly affirms the right to hold non-conformist historical views and the right to be wrong. While it is not the function of lawyers or judges to establish what historical truth is, Article 20 of the Covenant imposes an obligation on governments to prohibit incitement to racial hatred or violence, the criminalization of which requires narrow definition of the elements of the crime.

     

Effectiveness of comparison overlays generated with DentalPrint software in bite mark analysis

Validation studies of the new DentalPrint software were carried out with experimental bite marks in pigskin. The bite marks were digitally photographed according to the ABFO guidelines for evidence collection. Dental casts used in the experiment were scanned in 3D and 2D, and comparison overlays were generated using DentalPrint and Adobe Photoshop software, respectively. Digitized photographs of the experimental bite marks and the biting edges obtained in the overlays were compared by two different examiners to analyze the impact of training and experience with the two methods. Receiver operating characteristic (ROC) analysis, sensitivity, specificity, and 95% confidence intervals for each cutoff point were calculated. The expert examiner using DentalPrint obtained the best results, with an area under the ROC curve of 0.76 (SE=0.057; CI at 95%=0.652-0.876). Fairly high specificity values were found for DentalPrint, and the best results were obtained for the cutoff value that discriminated between the examiner's response "biter" and the rest of the possible (specificity 97.9%, CI at 95%=93.2%-99.6%). Therefore, the results presented here indicate that DentalPrint is a useful, accurate tool for forensic purposes, although further research on the comparison process is needed to enhance the validity of bite mark analysis.
