Based on the experiences of Colombia, Brazil and Bolivia, the paper proposes a general analytical framework for participatory mechanisms. The analysis is oriented to detect the incentives in each system and theethics and behavior sustaining them. It investigates about the sustainability of participatory democracy, in the face of tensions with representative democracy. The article presents a theoretical framework built from theseexperiences of institutional design and political practice, and confronts it against the theoretical conceptualizationsof participatory democracy in Bobbio, Sartori, Elster and Nino, among others. In this context, different waysin which those schemes can be inserted in the political systems become apparent, along with the variables thatresult from combining elements of direct, representative and participatory democracy”

Descriptive herd variables (DVHE) were used to explain genotype by environment interactions (G x E) for milk yield (MY) in Brazilian and Colombian production environments and to develop a herd-cluster model to estimate covariance components and genetic parameters for each herd environment group. Data consisted of 180,522 lactation records of 94,558 Holstein cows from 937 Brazilian and 400 Colombian herds. Herds in both countries were jointly grouped in thirds according to 8 DVHE: production level, phenotypic variability, age at first calving, calving interval, percentage of imported semen, lactation length, and herd size. For each DVHE, REML bivariate animal model analyses were used to estimate genetic correlations for MY between upper and lower thirds of the data. Based on estimates of genetic correlations, weights were assigned to each DVHE to group herds in a cluster analysis using the FASTCLUS procedure in SAS. Three clusters were defined, and genetic and residual variance components were heterogeneous among herd clusters. Estimates of heritability in clusters 1 and 3 were 0.28 and 0.29, respectively, but the estimate was larger (0.39) in Cluster 2. The genetic correlations of MY from different clusters ranged from 0.89 to 0.97. The herd-cluster model based on DVHE properly takes into account G x E by grouping similar environments accordingly and seems to be an alternative to simply considering country borders to distinguish between environments.

The objective of this study was to determine whether there is a genotype by environment interaction (GxE) for dairy buffaloes in Brazil and Colombia. The (co)variance components were estimated by using a bi-trait repeatability animal model with the REML method. Each trait consisted in the milk yield obtained in both countries. Contemporary group (herd, year and season of parity) and age at parity (linear and quadratic covariate) fixed effects, along with the additive genetic, permanent environment, and the residual random effects were included in the model. Genetic, permanent environmental and residual variance and heritabilities were different for both countries. The genetic correlations for milk yield between Brazil and Colombia were low (between 0.10 and 0.13), indicating a GxE interaction between both countries. Knowing that this interaction influences the genetic progress of buffalo populations in Brazil and Colombia, we recommend choosing sires tested in the country they will be used, along with conducting joint genetic evaluations that consider GxE interaction effects.

Latin America is known as the most unequal region in the world, where extreme displays of wealth and exposure to scarcity lay bare in the urban landscape. Inequality is not just a social issue; it has considerable impact on economic development. This is because social inequality generates instability and conflict, which can create unsettling conditions for investment. At the macro level, social inequality can also present barriers to economic development, as most government policies and resources tend to be directed in solving social conflict rather than to promote and generate growth. This is one of the reasons usually cited in explaining the development gap between Latin America and other emerging economies, take East Asia for example - they have similar policies to those applied recently in Latin America, but are achieving better growth. The other reason cited is institutional; this includes governance as well as property rights and enforcement of contracts. The latter is the focus of this chapter.

Blood-sucking flies are important parasites in animal production systems, especially regarding confinement conditions. Haematobia irritans, the horn fly, is one of the most troublesome species within bovine production systems, due to the intense stress imposed to the animals. H. irritans is one of the parasites of cattle that cause significant economic losses in many parts of the world, including South America. In the present work, Brazilian, Colombian and Dominican Republic populations of this species were studied by Random Amplified Polymorphic DNA(RAPD) to assess basically genetic variability between populations. Fifteen different decamer random primers were employed in the genomic DNA amplification, yielding 196 fragments in the three H. irritans populations. Among h. irritans samples, that from Colombia produced the smallest numbers of polymorphic hands. This high genetic homogeneity may be ascribed to its geographic origin, which causes high isolation, low gene flow, unlike the other American populations, from Brazil and Dominican Republic. Molecular marker fragments, which its produced exclusive bands, detected in every sample enabled the population origin to be characterized, but they are also potentially useful for further approaches such as the putative origin of Brazilian, Colombian and Dominican Republic populations of horn fly from South America. Similarity indices produced by chemo metric analysis showed the closest relationships between flies from Brazil and Dominican Republic, while flies from Colombia showed the greatest genotypic differentiation relative to the others populations.

This study builds on the Corporate governance and development of capital markets in Latin America report published by the Development Bank of Latin America (CAF) and the Economic Commission for Latin America and the Caribbean (ECLAC), which looked at the regulatory framework related to the principles of corporate governance in the region and assessed its contribution to the development of capital markets. This book complements the previous study and is the result of a joint effort by CAF, the Inter- American Development Bank (IDB) and ECLAC to identify the key elements of corporate governance for determining debt instrument issuance risk in potential conflicts of interest arising from relationships among shareholders, executives and bondholders

Currently bilateral trade between Canada and Colombia is low. In 2003, this trade amounted to US $489 million, with Colombian imports from Canada totaling US $ 213 million (DOTS, 2004). Canada supplied approximately 4.0% of Colombia’s total trade (total imports and total exports), in contrast Colombia supplied only around 0.1% of the Canadian total trade. In 2005, Colombia was the third largest Canadian partner in South America after Brazil and Venezuela. The objective of this paper is to analyze the trade performance between Canada and Colombia using a modified gravity equation to identify the most relevant historical factors that have shaped the evolution of this bilateral trade in the long run (during the period from 1953 to 2003). The analysis includes traditional economic variables (such as population and income of the importing and exporting countries). In order to understand the qualitative nature of the evolution of this bilateral trade the second objective is to review the evolving nature of trade including commodity composition and trade characteristics.

Objective.To estimate the excess length of stay in an intensive care unit (ICU) due to a central line–associated bloodstream infection (CLABSI), using a multistate model that accounts for the timing of infection. Design.A cohort of 3,560 patients followed up for 36,806 days in ICUs. Setting.Eleven ICUs in 3 Latin American countries: Argentina, Brazil, and Mexico. Patients.All patients admitted to the ICU during a defined time period with a central line in place for more than 24 hours. Results.The average excess length of stay due to a CLABSI increased in 10 of 11 ICUs and varied from −1.23 days to 4.69 days. A reduction in length of stay in Mexico was probably caused by an increased risk of death due to CLABSI, leading to shorter times to death. Adjusting for patient age and Average Severity of Illness Score tended to increase the estimated excess length of stays due to CLABSI. Conclusions.CLABSIs are associated with an excess length of ICU stay. The average excess length of stay varies between ICUs, most likely because of the case‐mix of admissions and differences in the ways that hospitals deal with infections.

Resumen: En esta propuesta se discuten las consideraciones éticas sobre la investigación, hechas en tres códigos, a saber, la ley 1090 de 2006, que rige el ejercicio profesional del psicólogo en Colombia, el Código de Ética Profissional do Psicólogo do Conselho Federal de Psicología en Brasil y el Código Nacional de Ética de la Federación de Psicólogos de la República Argentina. El análisis de los preceptos sobre trato con personas, consentimiento informado y manejo de información, así como las investigaciones con animales, permiten apreciar carencias y fortalezas en cada país, además de las particularidades propias de una concepción del rol del psicólogo como investigador en la sociedad actual.

Maria Graham, escritora inglesa, nasceu perto de Papscastle em 19 d e junho de 1785 e morreu em Londres, em 28 de novembro de 1842. Casada com o capitão Thomas Graham comandante da fragata Doris fez em sua companhia a sua primeira viagem ao Brasil, em 1821, quando se dirigia ao Chile. Em 1824, já viúva, retornou ao Rio de Janeiro como preceptora de D. Maria da Glória, filha do Imperador D. Pedro I e de Dona Leopoldina. Permaneceu no país até setembro de 1825, quando retornou para Londres por motivos políticos. Mais tarde, casou-se com Augustus Earle Calcott e passou a assinar suas obras literárias como Lady Calcott. ‘Journal of a voyage to Brazil’ relata as viagens da autora ao Brasil. Descreve o país, seus habitantes e os costumes das diferentes classes sociais, principalmente em Pernambuco, na Bahia e no Rio de Janeiro. Constitui importante fonte de informações sobre a época da independência e uma das melhores publicações do século XIX. As ilustrações, com desenhos da autora, são excelentes. De acordo com Borba de Moraes ‘a Catholic University Library em Washington (Oliveira Lima Collection) possui um exemplar que pertenceu à própria autora, onde ela fez correções e anotações para uma segunda edição, mas que nunca chegou a ser publicada. Essas anotações são muito importantes, sobretudo para a história da revolução de Pernambuco e a atuação de Cochrane. Quanto aos acontecimentos de sua vinda ao Rio de Janeiro como preceptora de Dona Maria da Glória, existe um diário que foi publicado por Rodolfo Garcia com preciosas notas e prefácio no volume 60 dos Anais da Biblioteca Nacional do Rio de Janeiro, assim como uma biografia de D. Pedro I e correspondência entre Maria Graham e a Imperatriz’
