COVID-19 and the Limitations of Official Responses to Gender-Based Violence in Latin America: Evidence from Ecuador

As the COVID-19 lockdowns were implemented, Latin American countries raced to announce plans to address gender-based violence in response to the increase in reports of intrafamily abuse. However, states' interventions had limited results. This article explores the Ecuadorian case. The Andean country's emergency strategy was based on reporting violence via the 911 emergency number, a plan that failed to consider that women quarantined with their aggressors would not have the opportunity to make the call. This article lays bare the extent of the gap between policy and practice in gender mainstreaming and the acute consequences of this during the pandemic.     

Physical Aggression, Spreading of Rumors, and Social Prominence in Early Adolescence: Reciprocal Effects Supporting Gender Similarities?

There is a robust association between aggression and social prominence by early adolescence, yet findings regarding the direction of influence remain inconclusive in light of gender differences across various forms of aggressive behaviors. The current study examined whether physical aggression and spreading of rumors, as two gender-typed aggressive behaviors that differ in overt displays of power, promote and/or maintain socially prominent status for girls and boys during non-transitional grades in middle school. Peer nominations were used to assess physical aggression, spreading of rumors, and “cool” reputation (social prominence) during three time points between the spring of seventh grade and spring of eighth grade. Participants included 1,895 (54 % female) ethnically diverse youth: 47 % Latino, 22 % African-American, 11 % Asian, 10 % White and 10 % Other/Mixed ethnic background. Cross-lagged path analyses were conducted to test the directionality of the effects, and gender moderation was assessed by relying on multi-group analyses. The analyses revealed mainly reciprocal associations for each form of aggression, suggesting that boys, as well as girls, can both gain and maintain their status by spreading rumors about their peers, just as they do by physically fighting and pushing others in urban middle schools. The implications of the findings for interventions are discussed.     

State terrorism: orientalism and the drone programme

This article builds on the recent and growing scholarship on the negative effects of the drone programme. Current literature has shown that the drone programme terrorises the civilian population that it keeps under surveillance. Furthermore, it has articulated the drone programme’s violence as biopolitical and its surveillance as a necropolitical technology of distinction. It is argued in this article that the Orientalist attitudes and logic necessary for drone targeting form the basis for the biopolitical and necropolitical component of the drone programme. This article explores the Orientalism that suffuses the US drone programme in order to juxtapose it with governmental discourses that characterise the drone programme and its surveillance as neutral and humane – demonstrating the gap between government discourses of modernity and the actual drone programme. The necropolitical logic of distinction used for targeting leads to the assimilation of those under the drone’s gaze to a population that can be put to death, leading the drone programme to operate indiscriminately. The biopolitical logic is visible in the US practices, which I argue constitutes terrorism with the corroboration of civilian testimonies.     

Risk evaluation for spoofing against a sensor supplied with liveness detection

The aim of this paper is to evaluate the risks associated with the use of fake fingerprints on a livescan supplied with a method of liveness detection. The method is based on optical properties of the skin. The sensor uses several polarizations and illuminations to capture the information of the different layers of the human skin. These experiments also allow for the determination under which conditions the system is deceived and if there is an influence respectively of the nature of the fake, the mould used for the production or the individuals involved in the attack.These experiments showed that current multispectral sensors can be deceived by the use of fake fingerprints created with or without the cooperation of the subject. Fakes created from direct casts perform better than those produced by fakes created from indirect casts. The results showed that the success of the attack is influenced by two main factors. The first is the quality of the fakes, and by extension the quality of the original fingerprint. The second is the combination of the general patterns involved in the attacks since an appropriate combination can strongly increase the rates of successful attacks.     

Vulnerabilities of fingerprint reader to fake fingerprints attacks

The purpose of this research is to assess the vulnerabilities of a high resolution fingerprint sensor when confronted with fake fingerprints. The study has not been focused on the decision outcome of the biometric device, but essentially on the scores obtained following the comparison between a query (genuine or fake) and a template using an AFIS system. To do this, fake fingerprints of 12 subjects have been produced with and without their cooperation. These fake fingerprints have been used alongside with real fingers. The study led to three major observations: First, genuine fingerprints produced scores higher than fake fingers (translating a closer proximity) and this tendency is observed considering each subject separately. Second, scores are however not sufficient as a single measure to differentiate these samples (fake from genuine) given the variation due to the donors themselves. That explains why fingerprint readers without vitality detection can be fooled. Third, production methods and subjects greatly influence the scores obtained for fake fingerprints.     

The forensic analysis of soil organic by FTIR

In order to elucidate the discriminating power of various soil analytical techniques, over 100 soils samples were analyzed using conventional analysis (i.e., color, percent organic and density gradient) and a novel FTIR technique. The FTIR technique involves collecting a spectrum of a soil sample that has been oxidatively pyrolysed, and therefore all organic have been degraded. This spectrum is subtracted from the spectrum of the same sample that contained the organic prior to pyrolysis. This resultant IR spectrum represents the organic portion of the sample. The use of organic components increases the discrimination in soils that are otherwise similar. We have illustrated the usefulness of this technique by selecting four soil samples, which have identical Munsel color values but can be discriminated by subtractive ETIR. We propose that the ETIR spectra of the organic portion of soil serves a useful purpose in forensic investigations.
