Corporate governance in Brazil, Chile, Colombia, Mexico and Peru: The determinants of risk in corporate debt issuance

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

Index of political instability in Brazil, 1889-2009

This article aims to develop an index of political instability (ins) in Brazil between 1889 and 2009, reflecting a wide-ranging set of multiple phenomena that represent conflicts between the different social groups. By presenting different definitions of what is understood by political instability in the economics literature and by using multiple historical events —coups d’état, civil conflicts, constitutional or unconstitutional overthrow and changes in the composition of 50% of the ministerial cabinet— different indicators are obtained which are then synthesized into a single index using the principal component technique, to obtain an ins for Brazil between 1889 and 2009.

Evaluation report of the regional workshop on the measurement of poverty in the Caribbean

1. The member and associate member countries of the Economic Commission for Latin America and the Caribbean/Caribbean Development and Cooperation Committee (ECLAC/CDCC) have committed to pursuing and achieving the Millennium Development Goals, a common set of goals and targets to bring all people up to minimum acceptable standards of human development by 2015. 2. However, in spite of various capacity-building initiatives, Caribbean countries continued to experience difficulties in addressing additional demands of monitoring and measuring progress created by the Millennium Development Goals and other Internationally Agreed Development Goals. Therefore, it was necessary to implement activities to ensure the further building/strengthening of institutional capabilities for generating reliable social, economic and environmental statistics among Caribbean States. 3. The ECLAC project entitled “Strengthening the Capacity of National Statistical Offices in the Caribbean Small Island Developing States to fulfil the Millennium Development Goals and other Internationally Agreed Development Goals” sought to build and strengthen institutional capabilities for generating and compiling reliable social, economic and environmental statistics in the Caribbean subregion, through the provision of technical support, as well as the conduct of training workshops for statisticians and policymakers. 4. Within the objectives of that project, ECLAC Subregional Headquarters for the Caribbean convened a regional training workshop on the measurement of poverty in the Caribbean in Port of Spain, to build the capacity of government officials and other relevant stakeholders. 5. The overall objective of the workshop was to develop and strengthen the national technical capacity of public officials in data processing, systematization and dissemination of poverty indicators and measurement in the Caribbean subregion. The workshop further sought to review and discuss the current approaches to poverty measurement and monitoring in an effort to identify methods to ensure that monitoring and reporting of the Millennium Development Goals were conducted according to internationally agreed upon methodologies. Furthermore, the workshop also intended to review different methods of poverty measurements, including the multidimensional methodology for the measurement of poverty. 6. Participants were introduced to different methods of poverty measurements and other aggregation proposals which would enable countries to better measure progress towards Goal 1 on poverty, report on it and apply evidence-based approaches to national policymaking and planning.

Determinants of unfair inequality in Brazil, 1995 and 2009

This article analyses the trend of unfair inequality in Brazil (1995-2009) using a nonparametric approach to estimate the income function. The entropy metrics introduced by Li, Maasoumi and Racine (2009) are used to quantify income differences separately for each effort variable. A Gini coefficient of unfair inequality is calculated, based on the fitted values of the non-parametric estimation; and the robustness of the estimations, including circumstantial variables, is analysed. The trend of the entropies demonstrated a reduction in the income differential caused by education. The variables “hours worked” and “labour-market status” contribute significantly to explaining wage differences imputed to individual effort; but the migratory variable had little explanatory power. Lastly, the robustness analysis demonstrated the plausibility of the results obtained at each stage of the empirical work.

Epidemiological and oral manifestations of HIV-positive patients in a specialized service in Brazil

The purpose of this study was to evaluate the prevalence of oral lesions in HIV-positive patients attending the Specialized Service for Infectious-contagious Diseases and Parasitoses of the Health Secretariat of the State of Pará (URE-DIPE/SESPA), in the city of Belém, PA, Brazil. A total of 79 HIV-positive patients (53 males and 26 females) were examined. Clinical and epidemiological evaluations were done by correlating the lesions with gender, race, chronological age, risk behavior and prevailing immune status (CD4+ cells count). Lesion location and the presence of associated factors, such as alcohol use, smoking and denture wearing, were quantified individually for each type of lesion using a diagnostic pattern based on the clinical aspects. Approximately 47% of the patients (n=37) presented some type of oral lesion. Candidiasis (28%) and periodontal disease (28%) were the most common, followed by cervical-facial lymphadenopathy (17.5%). Other lesions observed were hairy leukoplakia, melanin hyperpigmentation, ulcerative stomatitis (aphthous), herpes simplex, frictional keratosis and pyogenic granuloma. This analysis presented some relevance as to the statistical data. Concerning CD4+ cells, most lesions manifested with the reduction of the CD count. There were a larger number of HIV-positive female heterosexual patients. Alcohol and/or smoking were strongly associated with the occurrence of hairy leukoplakia in these patients. Candidiasis and periodontal disease were the most common oro-regional clinical manifestations in the patients.

The history of the introduction of the giant river prawn, Macrobrachium cf. rosenbergii (Decapoda, Palaemonidae), in Brazil: new insights from molecular data

The giant river prawn, Macrobrachium cf. rosenbergii, is one of the most cultivated freshwater prawns in the world and has been introduced into more than 40 countries. In some countries, this prawn is considered an invasive species that requires close monitoring. Recent changes in the taxonomy of this species (separation of M. rosenbergii and M. dacqueti) require a re-evaluation of introduced taxa. In this work, molecular analyses were used to determine which of these two species was introduced into Brazil and to establish the geographic origin of the introduced populations that have invaded Amazonian coastal waters. The species introduced into Brazil was M. dacqueti through two introduction events involving prawns originating from Vietnam and either Bangladesh or Thailand. These origins differ from historical reports of the introductions and underline the need to confirm the origin of other exotic populations around the world. The invading populations in Amazonia require monitoring not only because the biodiversity of this region may be affected by the introduction, but also because admixture of different native haplotypes can increase the genetic variability and the likelihood of persistence of the invading species in new habitats.

Biochemical polymorphisms and genetic relationships between Brazilian and foreign breeds of pigs reared in Brazil

Foi investigada a variabilidade genética de 14 sistemas protéicos codificados por 15 locos estruturais em amostras de sangue de suínos das raças Piau e Caruncho. Os resultados foram comparados com àqueles obtidos previamente para amostras de Landrace, Large White, Duroc e Mouro. O grau de variabilidade genética obtida para Piau (He=0,114) foi similar àquelas estimadas para outras raças criadas no Brasil (Landrace, He=0,116; Large White, He=0,119; Duroc, 0,095; Mouro, He= 0,130). Caruncho apresentou a menor variabilidade (He= 0,056). A partir das freqüências gênicas dos locos polimórficos, foi calculada a eficiência de cada sistema para testes de paternidade e as probabilidades combinadas de exclusão de paternidade foram estimadas em 58% para Piau e 36% para Caruncho. Análises das distâncias genéticas revelaram que a raça mais próxima da Piau foi a Landrace (D=0,042). Caruncho apresentou as maiores divergências em relação a todas as raças comparadas, que variaram de 0,107 (com Landrace) a 0,176 (com Duroc). A árvore construída através de UPGMA e Distância de Rogers mostrou uma topologia na qual Piau e Mouro se uniram as raças Européias (Landrace e Large White), e Caruncho está separado de todas as demais raças. Os resultados das análises das amostras de Caruncho devem ser interpretados com cautela, uma vez que o número de animais estudados foi pequeno.

Genetic characterization of native and introduced populations of the neotropical cichlid genus Cichla in Brazil

A molecular phylogenetic analysis based on mitochondrial 16S ribosomal DNA and Control Region sequences from native and introduced populations was undertaken, in order to characterize the introduction of Cichla (peacock bass or tucunaré) species in Brazil. Mitochondrial DNA haplotypes found in introduced fish from Minas Gerais state (southeastern Brazil) clustered only with those from native species of the Tocantins River (Cichla piquiti and C. kelberi), thereby suggesting a single or, at most, few translocation acts in this area, even though with fish from the same source-population. Our study contributes to an understanding of the introduction of Cichla in regions of Brazil outside the Amazon basin, and adds phylogenetic data to the recently describe Cichla species, endemic from the Tocantins-Araguaia basin.
