Distribution of the minutiae in palmprints: Topological and sexual variability

Palmprints have been systematically less studied than fingerprints, despite being of great use in the identification process. In Spain, they were not included in Automated Fingerprint Identification Systems (AFIS) until 2009. Very few investigations performed within the field of palmprints have assessed the sexual and population variability of the number and distribution of minutiae on its surface, despite the fact that these particularities are the basis for personal identification in forensic science. That is why a study was conducted to assess total, bimanual, and sexual density per morphological regions (superior or distal, thenar, and hypothenar) and per counting areas of 1 cm² on 120 palmprints obtained from 30 male and 30 female individuals of Spanish nationality. Also, the frequency in the location of each type of delta or triradius (a, b, c, d, and t) per count area was calculated. Results have shown a topological variability in the distribution of the density of minutiae, which is similar between sexes and a specular effect between both hands. The most frequent locations of the deltas coincide with areas of high minutiae density. It has also been shown that there are sexual differences in the total number of minutiae, which cannot be due to sexual dimorphism in adult hand size, since minutiae are established at an early stage of fetal development and their number will not change during later postnatal growth. These differences can only be attributed to genetic factors related to sexual determination.     

3D forensic facial approximation: Implementation protocol in a forensic activity

The primary objective of this paper is to report on the successful implementation of forensic facial approximation in a real case in the forensic context. A three‐dimensional (3D) facial approximation protocol of the skull was performed with free software, applying techniques in a virtual environment that have already been consolidated in the literature. The skull was scanned with the photogrammetry technique, the digital replica was imported in the Blender software (Blender Foundation, Amsterdam) and individualized model sketches of the face were traced with the MakeHuman software (MakeHuman Org) according to the anthropological profile of the victim. The face created was imported in Blender, where it was adapted, modeled, and sculpted on the 3D skull and its soft tissue markers, using an American open‐source application of the technique in the digital environment. The face created in a virtual environment was recognized and legal identification procedures were started, resulting in the more agile delivery of the disappeared body to its next of kin. It is therefore concluded that facial approximation may not be a primary method of human identification, but it can be satisfactorily applied in the forensic field as an individual recognition resource. It has great value in narrowing the search, reducing the number of alleged victims, and leading to identification tests, therefore significantly reducing the number of genetic DNA (deoxyribonucleic acid) tests—which are considered costly for the State or Federation—and consequently reducing the waiting time before delivery of the body to its family.     

Hypocrisy as a crisis response? Assessing changes in talk,decisions, and actions of the European Commission in EU environmental policy

In this article, we assess the changing role of the European Commission in EU environmental policy. In line with organizational theory, we expect organizational hypocrisy, namely a decoupling of talk, decisions, and actions, to characterize the Commission's behaviour in the aftermath of the financial and economic crisis. We analyse the extent to which the Commission (1) promotes environmental matters and concepts in press releases and public statements; (2) proposes new and stricter environmental policy changes; and (3) takes action against member states in cases of non-compliance between the years 2000 and 2016. Our empirical analysis reveals that the Commission has indeed moved towards a pattern of hypocritical policy entrepreneurship in the post-crisis period. We argue that the decoupling of talk, decision, and action allows the European Commission to keep up its reputation as an environmental policy entrepreneur while, at the same, satisfying member states’ preference for economic recovery and less environmental regulation.     

Conflict or Cooperation? Political Relations between Governors and Mayors in Major Cities in Argentina

This article explores the nature of the relations between the governors and the mayors of major cities in Argentina. The vast majority of the literature assumes that municipal governments in Argentina are weak, and that mayors therefore align with the provincial authorities. This study argues that there is more diversity in the relations between officials of both levels, and that, in some cases, these relations are openly contentious. Four ideal types of relations are identified, based on political affiliation and type of relation, through the systematisation of 43 cases of major Argentine cities.     

The Transaction Costs of Government Responses to the COVID-19 Emergency in Latin America

The COVID-19 pandemic has created a crisis that is challenging national and local governments to innovate in their responses to novel problems. Despite similarities to the challenges confronted in developed countries, for Latin American governments, these problems are amplified by structural obstacles such as social inequalities. These countries must respond with capacities and resources that are often limited by spoils systems and by social and political polarization. This essay provides an overview of some innovative practices in Argentina, Brazil, Chile, Colombia, and Mexico. In particular, this essay concentrates on some salient collaborative efforts in the region. To draw lessons from these practices, the authors focus on the formal and informal institutions that facilitate or obstruct collaboration across jurisdictions. The findings are discussed in terms of the transaction costs of collaboration identified in these experiences.

How do we provide the digital footprint with eternal rest? Some criteria for legislation regulating digital wills

This article analyses the implications of the death of digital service users on their digital footprint and assesses some of the solutions—contractual and legislative—that have been posited to date by digital service providers and by Parliaments of a few countries. In view of the different initiatives analysed, and the experience gained in their implementation, the paper presents legal certainty, effectiveness and transparency as criteria that should guide the regulation of the digital footprint in the case of death. These criteria must allow for the adoption or regulation of mechanisms for managing the digital footprint of digital service users to be clear and trustworthy for them and efficient and easily recognized and adopted by digital service providers.
