Phylogeography and genetic variation of Triatoma dimidiata, the main Chagas disease vector in Central America, and its position within the genus Tria…

2008

Background Among Chagas disease triatomine vectors, the largest genus, Triatoma, includes species of high public health interest. Triatoma dimidiata, the main vector throughout Central America and up to Ecuador, presents extensive phenotypic, genotypic, and behavioral diversity in sylvatic, peridomestic and domestic habitats, and non-domiciliated populations acting as reinfestation sources. DNA sequence analyses, phylogenetic reconstruction methods, and genetic variation approaches are combined to investigate the haplotype profiling, genetic polymorphism, phylogeography, and evolutionary trends of T. dimidiata and its closest relatives within Triatoma. This is the largest interpopulational …

Do cultural differences influence batterer intervention program outcomes?: a study with Spanish and Latin American offenders

2015

En este estudio se analiza, en primer lugar, si existen diferencias entre hombres latinoamericanos inmigrantes y españoles condenados por violencia contra la mujer en las relaciones de pareja, en relación a sus actitudes hacia la violencia (i.e., gravedad percibida, culpabilización de la víctima y aceptabilidad de la violencia), atribución de responsabilidad, sexismo y riesgo de reincidencia al inicio de un programa de intervención con maltratadores. En segundo lugar, se comprueba si existen diferencias al finalizar la intervención en los resultados del programa entre inmigrantes latinoamericanos y nativos. Para ello se utiliza una muestra de 278 participantes que han finalizado un programa…

Domain shuffling between Vip3Aa and Vip3Ca: chimera stability and insecticidal activity against European, American, African, and Asian pests

2020

The bacterium Bacillus thuringiensis produces insecticidal Vip3 proteins during the vegetative growth phase with activity against several lepidopteran pests. To date, three different Vip3 protein families have been identified based on sequence identity: Vip3A, Vip3B, and Vip3C. In this study, we report the construction of chimeras by exchanging domains between Vip3Aa and Vip3Ca, two proteins with marked specificity differences against lepidopteran pests. We found that some domain combinations made proteins insoluble or prone to degradation by trypsin as most abundant insect gut protease. The soluble and trypsin-stable chimeras, along with the parental proteins Vip3Aa and Vip3Ca, were tested…

Farewell to leadership? Ideas of hegemony and counter-hegemony in the Americas

2014

Mainstream International Relations and Foreign Policy Analysis have often concentrated on material factors and actors’ preferences, leaving out ideational dynamics. However, US–Latin American relations in general seem fraught with ideas, narratives and historical references re-articulated from time to time on both sides. In his campaign, Barack Obama announced a fresh start of US–Latin American relations, promising to “restore American leadership in Latin America”, at the same time creating “a new partnership for the Americas”, combining two narratives in US–Latin American policy. “Leadership”, enshrined in the Monroe Doctrine and the Roosevelt corollary, which declared Latin America the “…

Internationally adopted children: a new challenge for pediatricians.

2006

Children adopted from abroad by Italian families have increased during the last years. Since 2001 to 2004 they have been more than 10,000, mainly from Eastern Europe, and all indications suggest that they will continue to increase. Most of the internationally adopted children reside in orphanage before adoption where they may experience malnutrition, exposure to infectious diseases, environmental deprivation, neglect. Moreover, their pre-adoptive records are scarcely reliable and their immunization status is not always adequate. The most common long-term problems of internationally adopted children concern developmental and scholastic delay especially if they come from a long and severely d…

Reciprocal vs nonreciprocal trade agreements: Which have been best to promote exports?

2019

The Doha Development Agenda recognizes the central role that international trade can play in the promotion of economic development. In fact, the increase of exports from developing countries to developed nations' markets has been considered a key element for developing countries to realize the potential benefits of globalization. Over the last decades, developed countries have provided preferential access to their markets to developing countries through nonreciprocal trade agreements. Moreover, developing countries have also participated in reciprocal trade agreements. This paper re-examines comparatively the effect of both kinds of trade agreements on exports from developing countries but …

A market of accents

2009

This paper describes the cultural semantics of internet courses in American accent. Such courses are offered by corporate providers to specific groups of customers: people in search of success in the globalized business environment. The core of such courses is an order of indexicality which stresses uniformity and homogeneity, producing an invisible accent that replaces existing ‘foreign’ (i.e. authentic, biographic) accents. It is a new form of commodified dialectology, which differs quite substantially from common state and academic attitudes towards dialects and accents. The procedures used by such private providers are instances of language policing aimed at the infinitely small stuff o…
