A Redução Da Maioridade Penal Diminui A ViolĂȘncia? EvidĂȘncias De Um Estudo Comparado
This paper tests the hypothesis that decreasing the age of criminal majority will reduce violence. Methodologically, the research design uses spatial analysis, descriptive and multivariate statistics to examine an original dataset created based on secondary sources. We focus on juvenile judicial system in comparative perspective centering in two variables: (1) age of criminal majority and (2) age of criminal responsibility. The general average of criminal majority tends to 18 years, while the average age of criminal responsibility tends to 11 years. The result shows a negative correlation between the age of criminal majority and homicides rates. That means that countries with lower age of criminal majority have higher rates of violence. With this paper we hope to contribute in the discussion regarding criminal majority reduction in Brazil and in the development of specific public policies to reduce violence.22111813

Soil cover plants on water erosion control in the South of Minas Gerais
Water erosion is responsible for soil, water, carbon and nutrient losses, turning into the most important type of degradation of Brazilian soils. This study aimed to evaluate the influence of three cover plants under two tillage systems on water erosion control in an Argisol at south of Minas Gerais state, Brazil. The cover plants utilized in the study were pigeon pea, jack bean and millet, under contour seeding and downslope tillage. Experimental plots of 4 x 12 m, with 9% slope, under natural rainfall were used for the quantification of losses of soil, water, nutrients, and organic matter. One experimental plot was kept without plant cover (reference). Higher erosivity was observed in December and January, although a great quantity of erosive rainfall was detected during the whole raining period. Contour seeding provided a greater reduction of water erosion than downslope tillage, as expected. The jack bean under contour seeding revealed the lowest values of soil, water, nutrients and organic matter losses
