Testing Discriminant Functions for Sex Determination from Deciduous Teeth*,†

Abstract: Three studies have proposed discriminant functions for sex determination from deciduous tooth crown dimensions, and this study tests the existing functions on a sample of 46 Portuguese immature skeletons of known sex, aged from birth to 10 years. Deciduous teeth were measured in their mesiodistal and faciolingual crown dimensions, and percentage of correct allocation accuracy in determining sex using each specific function was determined. Discriminant functions were also calculated from data collected for this study and tested using cross‐validation. Results show poor overall accuracy (33.3–75%) and poor cross‐validation (46.2–60.0%). This is related to low sexual dimorphism in deciduous tooth crown size, as well as differences in degree of sexual dimorphism and in overall tooth size between different samples. For these reasons, deciduous crown size does not seem to show significant forensic value as discriminator of sex, particularly when methods developed on one population are applied to individuals of another population.     

Ambivalent sexism,empathy and law enforcement attitudes towards partner violence against women among male police officers

Police attitudes towards partner violence against women (PVAW) can play an important role in their evaluation and responses to this type of violence. The present study aims to examine ambivalent sexism and empathy as determinants of male police officers' law enforcement attitudes towards PVAW. The study sample was composed by 404 male police officers. Results suggested that male police officers scoring low in benevolent sexism expressed a general preference for unconditional law enforcement (i.e. regardless of the victim's willingness to press charges against the offender), whereas those scoring high in benevolent sexism expressed a preference for conditional law enforcement (i.e. depending on the willingness of the victim to press charges against the offender). Results also showed that police officers scoring high in empathy and low in hostile sexism were those who expressed a general preference for unconditional law enforcement. The presence of sexist attitudes and low levels of empathy among some police officers, and their influence on law enforcement attitudes, highlights not only the importance of specific training, but also the need to pay attention to the selection process of police officers dealing with PVAW.     

Distributive Effects of Regional Trade Agreements on the ‘Small Trading Partners’: Mercosur and the Case of Uruguay and Paraguay

It is disputed whether trade liberalisation processes are sufficient for reducing poverty and inequality. We explore how ‘gains from trade’ have been distributed in the two minor trade partners of Mercosur, Uruguay and Paraguay, by analysing the impact of trade liberalisation on poverty and inequality through two main transmission channels: prices and income. In the case of Uruguay, trade liberalisation favoured a reduction in poverty indicators but had an almost zero effect on income inequality. In the case of Paraguay, trade liberalisation had a markedly negative impact in terms of poverty yet income distribution improved. We conclude that in the case of Mercosur, the effect of trade on poverty and income inequality varies per country and per region. In particular, we conclude that trade integration policies cannot be regarded as ‘poverty-alleviating’ per se.     

An Unusual Pattern of Decomposition Associated with Suicidal Electrocution in a Bath

A 51‐year‐old man was found dead face down and partially submerged in a bathtub alongside two hairdryers. The hairdryers had continued to work, as the victim had bypassed the electrical board of the house prior to dropping them into the water. This had resulted in death due to electrocution, with subsequent heating of the bath water causing marked putrefaction and softening of the immersed body parts. The back and feet, which were not submerged, were preserved. The degree of anterior decomposition was not in keeping with the postmortem interval; however, regional decomposition with sparing of the back and feet provided a clue at autopsy as to the sequence of events. Individuals with training in, or knowledge of, electrical circuitry are capable of modifying domestic wiring so that safety switches and/or fuses can be bypassed ensuring that electrical devices will continue to function even while under water.     

Paisaje antes de la batalla. Notas sobre el contexto de la guerra contra las drogas en México

Mexico’s security crisis and Felipe Calderón’s (2006-2012) security strategy had its roots in drug trafficking, the prohibition of drugs, contraband and the border shared with the United States. Standard accounts of the violence experienced in the country, which reduce it to confrontations between drug cartels, are of little use. This article presents part of the context in which the security crisis developed, putting it in a historical perspective, and attempting to take a step towards a more nuanced interpretation. It holds that drug trafficking between Mexico and the United States is a complex, many-sided reality which admits dense symbolic elaboration. Apart from the very concrete shipping of drugs, drug trafficking is part of Mexico’s relation with the United States, a register that imbues the asymmetry between both countries with meaning, a space of political negotiation and a resource of American global diplomacy which is crystallized in a clandestine foreign policy system. Furthermore, through the demystification of the imagery that envelopes organized crime, corruption and contraband are examined, conceiving these two as phenomena that are integrated organically into borderland society.     

Does Drug Trafficking Impact Terrorism? Afghan Opioids and Terrorist Violence in Central Asia

ABSTRACT

The relationship between drug trafficking and terrorism remains a contentious issue. While some assert that drug trafficking is a strong predictor of terrorism, others contest this observation. This study focuses on the impact of the Afghan opioid trade on terrorist violence in Central Asia, a region of drug transit states. We employ Geographic Information Systems–enabled visualizations of the drug trade and terrorism as well as statistical tests to study the drug–terror relationship at the subnational level. Our findings lend support to the argument that the drug trade facilitates terrorism, but we also find that the drug–terror relationship is multifaceted, complex, and intimately linked to the state.     

中国的发展:一种新的进步观

根据会议程序,我最后一个发言,据此,我可以听到这次会议的很多东西,我确实也同意这些看法。我们知道,拉丁美洲有2.4亿贫困人口,对我们治理国家的能力来讲这是一个更大的考验。我们知道,在复杂和缺乏必要规则的国际经济领域,拉美与中国的贸易额达到700亿美元。我同意对拉美大陆与中国发展政治关系重要性的分析。因此,值此次关于当前拉丁美洲发生的变化和面临的机遇研讨会的召开,请允许我从大概不同的角度补充问题。一对双方必不可少的对话首先,我认为,中国与拉丁美洲和加勒比的对话对双方来讲都具有实质性意义。因为我们是在21世纪时期构建关…
