La desigualdad regional y productiva puede originarse a partir del proceso de modernización agrícola, donde una parte de los agentes son capaces de incorporar y absorber el contenido tecnológico, pero otros permanecen al margen no solo del entorno organizacional innovador, sino también de los procesos de aprendizaje y difusión de las nuevas técnicas y conocimientos productivos. Aquí se analiza la agricultura familiar, comparándola en términos regionales y por grupos de productores con alto, medio y bajo contenido tecnológico. Además, se calcula el índice de desigualdad productiva (Gini del ingreso bruto) de las regiones Norte, Nordeste, Centro-Oeste, Sudeste y Sur. Se argumenta que, frente a la diferenciación regional, la envergadura de los emprendimientos y los diversos niveles de incremento tecnológico, las políticas públicas deben tender a reducir las diferencias perjudiciales para la difusión de los nuevos conocimientos y el aumento de la productividad de los agentes, proporcionando una mayor inclusión productiva.

Nature Protection Areas (NPA) are important in the modern world, although still created with no well-defined criteria, overall in state and municipal spheres. In addition, there are no consistent information on the existence or factors that influence the creation and distribution of these areas. The present work had the objectives of identifying the Nature Protection Areas in Minas Gerais, Brazil, considering the municipalities and their mesoregions; perform a space-temporal analysis of the NPAs in Minas Gerais; relate the existence of NPAs with the Municipal Human Development Index (MHDI) and the municipal Gini Index (GI); relate the existence of NPA with the space-temporal and population density of each municipality; relate the Gross Domestic Product (GDP) with the presence of NPAs; relate the existence of NPAs with the occurrence of preservation areas in municipalities within the Atlantic Forest Biome; and verify the influence of the Ecological Sales and Services Tax (Ecological ICMS) institute over the creation of municipal NPAs in Minas Gerais. To reach these objectives, we researched databases, governmental websites, contacted managers and sent questionnaires to the 853 municipalities of Minas Gerais. After tabulating the data, statistical tests were applied to verify possible correlations. The results showed that the state has 9.26% of its territory protected, with the predominance of units of Sustainable Use, especially Environmental Protection Areas, which constitute 69.9% of this area. Only 1.96% of the territory are protected by Integral Protection (IP). We found no correlation between MHDI and the presence of NPAs. However, we verified that municipalities with IP units present higher GI when compared to the others, suggesting that the presence of this conservation unit (CU) model may be associated to social inequality. The results also showed a higher concentration CU in regions that use little of its natural resources as main economic basis and in municipalities with higher GDP. We also registered a positive correlation between the size of the municipalities, of the mesoregions, preserved area of the Atlantic Forest and population density. The Ecological ICMS did not contribute for a better IP in the state and, currently, does not represent an incentive to the creation of CU in Minas Gerais, even in the case of Environmental Protection Areas. This work registered a high degree of vulnerability if the protection system in this state, based on low restriction conservation units.

Se analiza la evolución de la desigualdad injusta en el Brasil (1995-2009) mediante un enfoque no paramétrico de la estimación de la función de ingresos. Se utilizaron las medidas de entropía de Li, Maasoumi y Racine (2009) a fin de cuantificar separadamente las diferencias de ingresos para cada variable de esfuerzo. Se calculó un coeficiente de Gini de desigualdad injusta basado en los valores ajustados de la estimación no paramétrica, analizándose la robustez para las estimaciones, incluyendo variables de circunstancias. La evolución de las entropías mostró reducción de la diferencia de ingresos atribuida a la educación como factor determinante. Las variables de horas trabajadas y situación en el mercado laboral explican significativamente las diferencias de salarios imputadas al esfuerzo individual, pero la variable migratoria reveló escaso poder explicativo. Finalmente, el análisis de robustez demostró la plausibilidad de los resultados de cada etapa de la ejecución empírica.

En este trabajo se efectúan mediciones, comparables con las metodologías internacionales, sobre la incidencia distributiva del impuesto a la renta y las transferencias públicas monetarias en 17 países de América Latina. Los resultados indican que la política fiscal juega un papel limitado en mejorar la distribución del ingreso disponible; el coeficiente de Gini baja apenas tres puntos porcentuales luego de la acción fiscal directa. En promedio, el 61% de esta reducción proviene de las transferencias públicas en efectivo y el resto de los tributos directos, reflejo del imperativo de fortalecer el impuesto a la renta personal. Las mediciones de encuestas de hogares permiten simular los efectos potenciales de reformas tributarias orientadas a aumentar las tasas medias efectivas del decil superior. Si esta recaudación adicional se destina a transferencias focalizadas, los efectos son muy significativos. En consecuencia, es necesario evaluar las reformas tributarias considerando el uso de estos recursos.

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.

This study uses internationally comparable methodologies to analyse the distributional impact of income tax and public transfers in 17 countries of Latin America. The results indicate that fiscal policy plays a limited role in improving the distribution of disposable income; the Gini coefficient decreased by barely three percentage points after direct fiscal action. On average, 61% of this reduction was due to public cash transfers and the rest to direct taxes, reflecting the pressing need for personal income tax to be strengthened. Analysis of household surveys gives an indication of the potential effects of tax reforms aimed at increasing the average effective tax rate of the top income decile. Allocating this additional revenue to targeted transfers would produce significant results. Consequently, tax reforms must be evaluated bearing in mind how those resources are used.

Considerando que a notícia impressa, televisual ou on-line não se restringe à elaboração do texto com aporte visual; de que, ao contrário, muitas vezes o projeto gráfico, o fotográfico e o videográfico, além da composição e estrutura de seus elementos, têm participação determinante na construção da notícia, este projeto parte da necessidade de um estudo crítico sobre a forma como a criança vem sendo representada (em imagens, sejam ilustrações ou fotografias) pelo jornalismo dirigido ao público adulto e geral. Diferentemente dos estudos no campo da Psicologia Social, do Direito ou da Comunicação com ênfase no agendamento social que dão destaque para temas de grande apelo social como violência, educação ou direito da criança e do adolescente, este estudo delimita seu objeto, abordagem e fundamentação na investigação da imagem e nas teorias da imagem e da mídia, abarcando, com isso, a variedade de temas que envolvem o universo infantil (desde os aspectos lúdicos e imaginativos até aqueles de maior dramaticidade e de grande apelo midiático). O objetivo deste projeto é demonstrar qual é a imagem (ou imagens) que a mídia brasileira contemporânea (jornais impressos e on-line) tem da criança (ou das crianças) e qual o comportamento dessa mídia no agendamento, pautagem e produção de tais imagens que representam as crianças em diversas situações. Para isso, serão analisadas as imagens de crianças apresentadas nos jornais Folha de S.Paulo, O Estado de S.Paulo, Jornal da Tarde, Jornal do Brasil e O Dia. Esses formam o corpus principal e dão enlevo para as imagens com produção em processo “mais imediato” – onde nota-se um tipo de jornalismo mais factual

Since the 60's, the population censuses have revealed a high degree of social inequality in Brazil. The concentration of income, as measured by the Gini index, showed persistently high since then. After the year 2001, we note that the trajectory stability is disrupted and the Gini index begins to show a downward trend. In relation to poverty, there has been two periods in recent history in which there was consistent decrease in the proportion of poor in the years immediately after the Real Plan in 2003 and in the year 2003 onwards. This research aimed to analyze poverty and income distribution in rural Brazil. In this crop sector, it is noted that the average perceived by the rural population is below the Brazilian income and, therefore, there is an increase in the number of poor. In addition, income in rural areas is less concentrated compared to the urban environment. Finally, as occurred in Brazil, there is a rural improvement in indicators of poverty and inequality in the last 10 years. Finally, this paper analyzes the changes that may have contributed to the fall in inequality and rural poverty, including the policy of rural settlement, the credit program to the family farmer (PRONAF) and rural retirement

Purpose: To test the association between income inequality and elderly self-rated health and to propose a pathway to explain the relationship. Methods: We analyzed a sample of 2143 older individuals (60 years of age and over) from 49 distritos of the Municipality of Sao Paulo, Brazil. Bayesian multilevel logistic models were performed with poor self-rated health as the outcome variable. Results: Income inequality (measured by the Gini coefficient) was found to be associated with poor self-rated health after controlling for age, sex, income and education (odds ratio, 1.19; 95% credible interval, 1.01-1.38). When the practice of physical exercise and homicide rate were added to the model, the Gini coefficient lost its statistical significance (P>.05). We fitted a structural equation model in which income inequality affects elderly health by a pathway mediated by violence and practice of physical exercise. Conclusions: The health of older individuals may be highly susceptible to the socioeconomic environment of residence, specifically to the local distribution of income. We propose that this association may be mediated by fear of violence and lack of physical activity. (C) 2012 Elsevier Inc. All rights reserved.

We study a five-parameter lifetime distribution called the McDonald extended exponential model to generalize the exponential, generalized exponential, Kumaraswamy exponential and beta exponential distributions, among others. We obtain explicit expressions for the moments and incomplete moments, quantile and generating functions, mean deviations, Bonferroni and Lorenz curves and Gini concentration index. The method of maximum likelihood and a Bayesian procedure are adopted for estimating the model parameters. The applicability of the new model is illustrated by means of a real data set.
