Testing for genetic structure in different urban Argentinian populations

Fifteen autosomal short tandem repeat (STR) markers (D3S1358, HUMTH01, D21S11, D18S51, PENTA E, D5S818, D13S317, D7S820, D16S539, CSF1PO, PENTA D, HUMvWA, D8S1179, HUMTPOX, FGA) were analyzed in 1734 individuals living in urban areas of cities from six different Argentinian provinces (Buenos Aires, Neuquén, Tucumán, La Pampa, San Luis, Santa Cruz) in order to determine if a common urban database could be used in Argentina for forensic purposes. Frequencies estimates, Hardy-Weinberg equilibrium (HWE), and other parameters of forensic interest were computed. Comparisons between the six populations, and with published data from one Native American population from Argentina and other urban populations from Argentina and Europe were also performed. Our results reveal evidences for population structure, both when testing for genetic differentiation and when comparing frequencies distributions between different pairs of populations. Therefore, caution should be taken when using a common pooled database with general forensic purposes in Argentina.     

Discursive mismatch and globalization by stealth: The fight against corruption in the Brazilian legal field

Law and globalization studies have documented how Global South lawyers compete over the adaptation of international norms. Yet, little is known about how this adaptation legitimates worldviews beyond the law. To advance this literature, this paper proposes a discourse-centered field analysis of the legal globalization of anti-corruption ideas in Brazil. It examines Brazilian lawyers' disputes over a 2016 anti-corruption bill. The bill supporters mobilize global anti-corruption discourses that are exogenous to the legal field to defend harsher criminal law. Their critics counter the reform by mobilizing endogenous legal ideas against criminal law expansion. In so doing, they do not challenge reformers' ideas about corruption. I show how this discursive mismatch leads to a form of globalization by stealth, whereby local dynamics allow global ideas to remain unchallenged in local fields.     

Value,Growth, Development: South American Lessons for a New Ecopolitics

Current debates on politics and ecology in South America offer a number of lessons on the controversy concerning ecosocialism and degrowth. Some recent experiments on the South American left show a strong emphasis on socialism while deploying conventional developmentalism including decisive social and environmental impacts. In this dispute the different conceptions of value are very clear. Original perspectives on Buen Vivir as a radical critique of development point to alternatives that are at the same time post-capitalist and post-socialist, alternatives in which the recognition of the intrinsic value of the non-human is a core component.     

Social perceptions on genomics in four Latin American countries. Ethical-legal implications]

The authors analyze under an ethical and legal perspective the consequences and anxieties generated by the human genome project in the population of four Latin American countries: Argentine, Chile, México and Perú, through bibliographical analysis and interviews done to biomedical researches, lawyers and legislators, students and lay civilians.     

Accuracy of four dental age estimation methodologies in Brazilian and Croatian children

ObjectiveTo compare and analyse the accuracy of four age estimation methods using the mineralisation stages of the permanent teeth (Cameriere et al. [16] [CAM], Liliequist and Lundberg [LLH] and Nolla without third molars [NOL7] or with them [NOL8]) in a mixed population of Brazilians and a homogeneous population of Croatians.MethodsOrthopantomograms of 930 Brazilians (366 males and 564 females) and 924 Croatians (365 males and 556 females) aged between 8 and 14.99 years were analysed using the CAM, LLH, NOL7 and NOL8 age estimation methodologies.ResultsLLH presented the best absolute differences (ADs) among both populations without sex stratification, while CAM presented the worst results. In addition, the mean differences revealed underestimations, except when the LLH and NOL7 methods were used for the Brazilians. When the sample was stratified by sex, the best AD values were found with NOL7 (0.80) for the Brazilians and with LLH (0.98) for the Croatians. When the sample was stratified by sex and age, CAM presented high accuracy at the early ages, and LLH presented high accuracy at the older ages. The results obtained with the Nolla methods (NOL7 and NOL8) were mostly similar, but NOL7 yielded slightly better results.ConclusionsThe values for the Brazilians and the Croatians were relatively similar, and the techniques were properly applied in both population samples. The best method for evaluating both countries was LLH, followed by NOL7, NOL8 and CAM.     

Extent and characteristics of woman batterers among federal inmates

Efforts to identify men who batter women in clinical settings have increased in recent years, but batterer research in United States federal prisons is lacking; low security federal prisons are logical places to consider batterer screening and treatment given the number of men, the domestic violence "risk markers" associated with these men and the likelihood they will be released and return to female partners. This study examined intake assessment data for 115 low security federal inmates. The inmates evidenced high levels of risk markers for woman battering, one in three (33%) acknowledged recent physical violence against women partners, 1 in 10 (13%) admitted severe violence, and the self-identified batterers showed more substance use and personality problems than other inmates. The findings suggest that batterer screening and treatment may be needed in federal prisons and that more research is warranted with a burgeoning male population that ultimately returns to society.     

The hidden electoral connection: analysing parliamentary questions in the Chilean Congress

Legislators in presidential countries use a variety of mechanisms to advance their electoral careers and connect with relevant constituents. The most frequently studied activities are bill initiation, co-sponsoring, and legislative speeches. In this paper, the authors examine legislators’ information requests (i.e. parliamentary questions) to the government, which have been studied in some parliamentary countries but remain largely unscrutinised in presidential countries. The authors focus on the case of Chile – where strong and cohesive national parties coexist with electoral incentives that emphasise the personal vote – to examine the links between party responsiveness and legislators’ efforts to connect with their electoral constituencies. Making use of a new database of parliamentary questions and a comprehensive sample of geographical references, the authors examine how legislators use this mechanism to forge connections with voters, and find that targeted activities tend to increase as a function of electoral insecurity and progressive ambition.     

Results of the GEP-ISFG collaborative study on the Y chromosome STRs GATA A10, GATA C4, GATA H4, DYS437, DYS438, DYS439, DYS460 and DYS461: population data

The Spanish and Portuguese ISFG Working Group (GEP-ISFG) carried out a collaborative exercise in order to asses the performance of two Y chromosome STR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The groups that reported correct results in all the systems were also asked to analyse a population sample in order to evaluate the informative content of these STRs in different populations. A total of 1020 males out of 13 population samples from Argentina, Brazil, Costa Rica, Macao, Mozambique, Portugal and Spain were analysed for all the loci included in the present study. Haplotype and allele frequencies of these eight Y-STRs were estimated in all samples. The lowest haplotype diversity was found in the Lara (Argentina) population (95.44%) and the highest (99.90%) in Macao (China). Pairwise haplotype analysis showed the relative homogeneity of the Iberian origin samples, in accordance with what was previously found in the European populations for other Y-STR haplotypes (http://www.ystr.org). As expected, the four non-Caucasian samples, Macao (Chinese), Mozambique (Africans), Costa Rica (Africans) and Argentina (Lara, Amerindians), show highly significant Phist values in the pairwise comparisons with all the Caucasian samples.     

Computational Approach to Identify Different Injuries by Firearms

Complications arise in the analysis of gunshot wounds to the maxillofacial region, when neither the projectile nor the gun is found at the crime scene. We simulated 5‐ and 15‐cm firing distances at a human mandible to investigate the external morphology of entrance wounds based on fire range. The ammunition models, .40‐caliber S&W, .380‐caliber, and 9 × 19‐mm Luger, were constructed with free‐form NURBS surfaces. In a dynamic simulation, projectiles were fired against mandibular body 3D model at 5 and 15 cm. All entrance wounds presented oval aspect. Maximum diameter and von Mises stress values were 16.5 mm and 50.8 MPa, both for .40‐caliber S&W fired at 5 cm. The maximum energy loss was 138.4 J for .40 S&W fired at 15 cm. In conclusion, the mandible was most affected by .40‐caliber S&W and morphological differences were observable in holes caused by different incoming projectile calibers fired at different distances.
