Towards universal social protection: Latin American pathways and policy tools

This book reflects on the public policies, programmes and regulatory frameworks that are taking a rights-based approach to expanding social protection coverage and benefits in Latin America, with a view to achieving universal coverage. The book’s discussion of the policy tools and programmes pursued in the region aims to provide the reader with technical and programmatic insights for assembling and coordinating public policies within consistent and sustainable social protection systems. The combination of normative orientations and stock of technical knowledge, together with advances regarding the rights-based approach to social protection within a life cycle framework, afford the reader not only a tool box of specific social protection instruments, but also an in-depth examination of related political economy aspects.

Determinants and home-country effects of FDI outflows: Evidence from Latin American countries

Foreign direct investment (FDI) by Latin American companies has increased sharply since the beginning of the 2000s. While most investment flows correspond to firms from large economies (i.e. Argentina, Brazil, Chile, Mexico and Colombia), small economies have also witnessed the increasing internationalisation of their domestic companies. This study examines the strategies followed by multinational enterprises (MNEs) from Latin America when they decide to invest in other countries, highlighting differences by sector and issuer-country size. To that end a new database, which comprises quantitative information on the main operations abroad of Latin American enterprises (both greenfield, and mergers and acquisitions) was constructed, based on fDi Markets and Thomson Reuters Datastream. It also investigates the home-country effects of outward foreign direct investment (OFDI) by conducting a case study of Costa Rica through a representative sample of firms investing abroad.

The People’s Republic of China and Latin America: the impact of Chinese economic growth on Latin American exports

The role of the People’s Republic of China in the world economy has grown substantially in recent decades, turning it into a strategic foreign trading partner for much of Latin America. Bilateral trade between the region and China totalled US$ 120 billion in 2009. This study analyses the income elasticity of the region’s exports to the country. The findings show that, assuming real gross domestic product (gdp) growth in China of about 7% a year, the value of Latin American exports to China (at 2005 prices) can be expected to increase by an average of about 10% a year between 2014 and 2019. In a more conservative scenario of 4.5% average annual growth in the Chinese economy over the period, exports would rise by about 7% a year.

This edition of the Economic and Social Panorama of the Community of Latin American and Caribbean States is a contribution by the Economic Commission for Latin America and the Caribbean (ECLAC) to the fourth Summit of Heads of State and Government of the Community of Latin American and Caribbean States (CELAC), to be held in Quito in January 2016. This document continues the work carried out since the first summit of CELAC held in Santiago and is a testimony to our ongoing commitment to work in collaboration with the countries of the region.

Pedagogical practices carried out during an in-service teachers education project: approaching history and philosophy of science to physics teaching

We report here part of a research project developed by the Science Education Research Group, titled: "Teachers’ Pedagogical Practices and formative processes in Science and Mathematics Education" which main goal is the development of coordinated research that can generate a set of subsidies for a reflection on the processes of teacher training in Sciences and Mathematics Education. One of the objectives was to develop continuing education activities with Physics teachers, using the History and Philosophy of Science as conductors of the discussions and focus of teaching experiences carried out by them in the classroom. From data collected through a survey among local Science, Physics, Chemistry, Biology and Mathematics teachers in Bauru, a São Paulo State city, we developed a continuing education proposal titled “The History and Philosophy of Science in the Physics teachers’ pedagogical practice”, lasting 40 hours of lessons. We followed the performance of five teachers who participated in activities during the 2008 first semester and were teaching Physics at High School level. They designed proposals for short courses, taking into consideration aspects of History and Philosophy of Science and students’ alternative conceptions. Short courses were applied in real classrooms situations and accompanied by reflection meetings. This is a qualitative research, and treatment of data collected was based on content analysis, according to Bardin [1].

Lipid levels in the second year of life among HIV-infected and HIV-exposed uninfected Latin American children

Background: Dyslipidemia is observed among older children and adults with HIV. We examined nonfasting cholesterol and triglycerides in two groups of 12-23-month-old Latin American children - HIV-infected vs. HIV-exposed but uninfected (HEU). Methods: HIV-infected and HEU children in Latin America and Jamaica were enrolled in an observational cohort. Eligibility for this analysis required having cholesterol and triglyceride results available during the second year of life. Results: HIV-infected (n = 83) children were slightly older at the time of lipid testing than the HEU (n 681). Forty percent of the HIV-infected children were on protease inhibitor-based antiretroviral therapy (ART); 41% were not on ART. There was no statistically significant difference in mean cholesterol concentrations (mg/dl) by HIV status; however, the HIV-infected children had higher mean triglyceride concentrations. The prevalence of high cholesterol (>200 mg/dl) and high triglycerides (>110 mg/dl) was higher among the HIV-infected vs. HEU. Among the HIV-infected children, mean cholesterol and triglyceride concentrations varied by ART. Children receiving no ART had a significantly lower mean cholesterol concentration. Those receiving protease inhibitor-containing ART had a significantly higher mean triglyceride concentration compared to the other two antiretroviral regimen groups. Conclusion: A greater proportion of HIV-infected children at 12-23 months have hyperlipidemia when compared to HEU children, with the highest triglyceride concentrations observed among those receiving protease inhibitor-containing ART, and the lowest cholesterol levels among those not receiving ART. Implications of these findings will require continued follow-up of HIV-infected children who initiate therapy early in life. (C) 2012 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins

The phylogeography of trypanosomes from South American alligatorids and African crocodilids is consistent with the geological history of South American river basins and the transoceanic dispersal of Crocodylus at the Miocene

Abstract Background Little is known about the diversity, phylogenetic relationships, and biogeography of trypanosomes infecting non-mammalian hosts. In this study, we investigated the influence of host species and biogeography on shaping the genetic diversity, phylogenetic relationship, and distribution of trypanosomes from South American alligatorids and African crocodilids. Methods Small Subunit rRNA (SSU rRNA) and glycosomal Glyceraldehyde Phosphate Dehydrogenase (gGAPDH) genes were employed for phylogenetic inferences. Trypanosomes from crocodilians were obtained by haemoculturing. Growth behaviour, morphology, and ultrastructural features complement the molecular description of two new species strongly supported by phylogenetic analyses. Results The inferred phylogenies disclosed a strongly supported crocodilian-restricted clade comprising three subclades. The subclade T. grayi comprised the African Trypanosoma grayi from Crocodylus niloticus and tsetse flies. The subclade T. ralphi comprised alligatorid trypanosomes represented by Trypanosoma ralphi n. sp. from Melanosuchus niger, Caiman crocodilus and Caiman yacare from Brazilian river basins. T. grayi and T. ralphi were sister subclades. The basal subclade T. terena comprised alligatorid trypanosomes represented by Trypanosoma terena n. sp. from Ca. yacare sharing hosts and basins with the distantly genetic related T. ralphi. This subclade also included the trypanosome from Ca. crocodilus from the Orinoco basin in Venezuela and, unexpectedly, a trypanosome from the African crocodilian Osteolaemus tetraspis. Conclusion The close relationship between South American and African trypanosomes is consistent with paleontological evidence of recent transoceanic dispersal of Crocodylus at the Miocene/Pliocene boundaries (4–5 mya), and host-switching of trypanosomes throughout the geological configuration of South American hydrographical basins shaping the evolutionary histories of the crocodilians and their trypanosomes.

Genetic characterization, population history and evolutionary medicine perspective in two native south american populations: Yanesha and Wichi

Two Amerindian populations from the Peruvian Amazon (Yanesha) and from rural lowlands of the Argentinean Gran Chaco (Wichi) were analyzed. They represent two case study of the South American genetic variability. The Yanesha represent a model of population isolated for long-time in the Amazon rainforest, characterized by environmental and altitudinal stratifications. The Wichi represent a model of population living in an area recently colonized by European populations (the Criollos are the population of the admixed descendents), whose aim is to depict the native ancestral gene pool and the degree of admixture, in relation to the very high prevalence of Chagas disease. The methods used for the genotyping are common, concerning the Y chromosome markers (male lineage) and the mitochondrial markers (maternal lineage). The determination of the phylogeographic diagnostic polymorphisms was carried out by the classical techniques of PCR, restriction enzymes, sequencing and specific mini-sequencing. New method for the detection of the protozoa Trypanosoma cruzi was developed by means of the nested PCR. The main results show patterns of genetic stratification in Yanesha forest communities, referable to different migrations at different times, estimated by Bayesian analyses. In particular Yanesha were considered as a population of transition between the Amazon basin and the Andean Cordillera, evaluating the potential migration routes and the separation of clusters of community in relation to different genetic bio-ancestry. As the Wichi, the gene pool analyzed appears clearly differentiated by the admixed sympatric Criollos, due to strict social practices (deeply analyzed with the support of cultural anthropological tools) that have preserved the native identity at a diachronic level. A pattern of distribution of the seropositivity in relation to the different phylogenetic lineages (the adaptation in evolutionary terms) does not appear, neither Amerindian nor European, but in relation to environmental and living conditions of the two distinct subpopulations.
