The objective of this work was to identify a possible relation between corporate governance, through the structure of the boards of directors and the levels of earnings management of Brazilian public companies. The study is characterized as a descriptive, of a hypothetical-deductive nature, with quantitative approach guided by the estimation model proposed by Kang and Sivaramakrishnan (1995). The sample was comprised by 56 companies, analyzed in the period from 2011 to 2014. The information on the companies were extracted from Economatica databank. For the data analysis, we used multivariate techniques, such as Pearson correlation and panel data in POLS, Fixed Effects and Random Effects approaches. Furthermore, we applied the mean comparison test ANOVA. The results obtained show that, generally, the organizations tend to follow the profile of boards of directors recommended by the codes of corporative governance. However, the characteristics of the composition of the board, regarding its size and the duality of positions that are not yet sufficient to be considered capable of inhibiting the discretionary practice of the studied companies. Relative the control variables, only size and return on equity presented no significant relation with result management. It is important to highlight that literature point many factors that explain the different impacts caused by the formation of the administration board in different regions or countries. Among the factors pointed, we highlight the legal system of the country, the economic and political development, the importance of the capital market, and the level of accounting education.

Biplot graphics are widely employed in the study of the genotypeenvironment interactions, but they are only a graphical tool without a statistical hypothesis test. The singular values and scores (singular vectors) used in biplots correspond to specific estimates of its parameters, and the use of uncertainty measures may lead to different conclusions from those provided by a simple visual evaluation. The aim of this work is to estimate the genotype-environment interactions, using AMMI analysis, through Bayesian approach. Therefore the credibility intervals can be used for decision-making in different situations of analyses. It allows to verify the consistency of the selection and recommendation of cultivars. Two analyses were performed. The first analysis looked into 10 regular commercial hybrids and all possible 45 hybrids obtained from them. They were assessed in 15 locations. The second analysis evaluated 28 hybrids in 35 different environments, with imbalance data. The ellipses were grouped according to the standard of interaction in the biplot. The AMMI analysis with a Bayesian approach proved to be a complete analysis of stability and adaptability, which provides important information that may help the breeder in their decisions. The regions of credibility, built in the biplots, allow to perform an accurate selection and a precise genotype recommendation, with a level of credibility. Genotypes and environments can be grouped according to the existing interaction pattern, which makes possible to formulate specific recommendations. Moreover the environments can be evaluated, in order to find out which ones contribute similarly to the interaction and those to be discarted. The method makes possible to deal with imbalanced data in a natural way, showing efficiency for multienvironment trials. The prediction takes into account instability and the interaction standard of the observed data, in order to establish a direct comparison between genotypes of both 1st and 2nd seasons.

Nas análises da integração na América Latina os críticos tendem a enfatizar o baixo grau alcançado em termos da importância relativa das transações regionais no total do comércio externo dos países da Região e a desconfiança de que os comprometimentos entre os países vizinhos podem estar afetando a exploração de oportunidades em outros mercados, mais dinâmicos. Os simpatizantes da integração, por outro lado, ressaltam os avanços conseguidos em comparação com o observado há duas décadas, em termos de relações comerciais, a intensificação dos fluxos de investimento direto entre países da Região e o coeficiente tecnológico mais elevado no comércio regional, em comparação com as exportações ao resto do mundo. Para ambos, contudo, persiste o entendimento de que – seja em comparação com outras regiões, seja em termos de evolução no tempo – era de se esperar que a integração latino-americana já tivesse atingido níveis bem mais expressivos do que o observado atualmente. Dois aspectos relevantes têm merecido menos consideração do que merecem nos debates sobre integração na América do Sul: a cooperação monetária entre os países e a relação de complementaridade e estímulo entre o sócio maior e os sócios menores. Existem claras diferenças no caso latino-americano em relação a ambas as dimensões. O baixo grau de avanço atingido no processo de integração e a limitada complementaridade produtiva encontrada na Região são indicativos de que um pouco mais de iniciativas nas direções discutidas aqui deveriam ser consideradas na agenda das negociações.
