Issues concerning deforestation have become a crucial theme in the environmental world debate. In this picture, Mato Grosso State has become an unfavorable example because it represents 36% of the accumulated deforestation in the Brazilian Amazon. In order to investigate the relationship between deforestation and income growth, this paper estimates an Environmental Kuznets Curve (EKC) for 139 cities of Mato Grosso through spatial econometrics. Using data for the year 2006, we estimate an EKC for the deforestation per capita against income per capita and other variables controlling the spatial effects. The preliminary results indicate that an EKC exists in a reversed U shape, i. e., the income growth reduces environmental effects from the maximum point. However, introducing a cubic term for the income, the economic growth would not reveal any relationship with the deforestation in the Mato Grosso State.

A idade ao primeiro parto em novilhas da raça Nelore é um importante índice a ser considerado na produtividade da pecuária de corte brasileira. Atualmente o gado Nelore é o mais difundido no Brasil, sendo considerado a principal raça de corte criada no país. O objetivo desta revisão foi comparar as informações sobre a característica reprodutiva tardia do gado Nelore com os recentes estudos sobre a antecipação da puberdade com o auxílio do manejo nutricional adequado, visando o aumento da produtividade. Foram utilizados basicamente três trabalhos, sendo um experimento realizado no Brasil, um trabalho apresentado por pesquisadores dos EUA e um artigo escrito pelo Dr. Guilherme de Paula Nogueira; além de artigos selecionados através dos seguintes descritores e boleadores: (Nelore OR Bos indicus) AND (Heifers OR Puberty) AND (Nutrition) AND (Economy). Dentre os 8 estudos obtidos, foram selecionadas 2 publicações em inglês datadas de 1991 e 2003. Mesmo a literatura sendo escassa neste assunto e em alguns aspectos contraditória, principalmente tratando-se da questão da viabilidade econômica da parição antecipada na pecuária de corte, pode-se concluir que a antecipação da puberdade depende de vários fatores tais como a genética, interação ambiental, nutrição, escore de condição corporal (ECC) e manejo. Além disso, mais pesquisas são necessárias e devem considerar a relação econômica da antecipação da puberdade em novilhas da raça Nelore dentro da bovinocultura de corte no Brasil

In this article, we analyze the works of Pero de Magalhães Gândavo in what we name colonial writings. They are texts written between the late 16 th century and the early 17th century. Gândavo’s intention, as with the other colonial writers, is to defend the interests of the settlers. With that, we counter historiography in general and Brazilian historiography in particular, which sees them as authors identified with metropolitan interests.

In this paper we analyze the question of character essayistic the historiography of the first half of the twentieth century. We examined this issue due to the emergence of a new trend on the historiographical colonization (School of Rio) who criticizes, among other things, the essay-like character in historiography. Whereas the criticism expressed how a new trend breaks with the existing historiography, we decided to examine this critical gauge. To promote the overcoming of a certain history is necessary to understand it in its historicity, that is, the motivations that led historians to examine the history of a given way. Of course, criticism is a moment of transcendence. But to be a radical departure is necessary to understand the historiography of historical criticism and not simply point their supposed mistakes, shortcomings and failures.

The theme of African-Brazilian culture is still little explored in the school environment, in spite of the 10.639/03 law which prescribes its mandatory teaching as well as that of African-Brazilian history and African culture in all schools, public and private, from the Elementary School level to High School. Moreover, this law emphasizes the importance that these cultures had in the formation of Brazilian society. Considering this issue, this paper aims to analyze the work Três anjos mulatos do Brasil (2011), by Rui de Oliveira, which brings together three sensitive and touching biographies, followed by beautiful and artistic pictures. hese narratives address the genius of three great artists –Aleijadinho, Mestre Valentim and Father José Maurício–, their styles, their creations and struggle for recognition, as well as the sufering they experienced, primarily caused by racial discrimination. Also, we intend to present in this text a suggested pedagogical use of the work by Oliveira, by applying the “Recepcional” method, as it was deined by Bordini and Aguiar (1993).

O presente artigo teórico procura analisar a educação brasileira enquanto elemento histórico e que hoje se encontra no dilema em seguir uma tendência nacional ou se submeter às regras do mundo globalizado. Para tanto, fazemos uma análise do surgimento da educação na era medieval, pré-moderna, moderna e contemporânea. Por fim questionamos se a educação é ainda uma instituição valorizada ou perdeu seu lugar, tornando-se um espaço desvirtuado.

The location of Jundiai-Mirim river basin, close to large urban centers and industrial parks, has contributed to the appreciation of their lands. Consequently, the region has an intense process of urbanization that resulted in an increasing environmental disturbance in the forest areas. Given the need to preserve existing natural vegetation, because the watershed is the source of water used to supply Jundiai, SP, this study evaluated changes in the environmental quality of the watershed forest fragments between 1972 and 2013. The environment quality was determined by evaluating nine indicators of environmental disturbance, obtained by techniques of Geoprocessing and integrated by Multicriteria Analysis. The results showed a constant tendency of deteriorating the environmental quality of natural vegetation between 1972 and 2013, attributed to the intense process of occupation of the watershed. It is concluded that: (a) urbanization and deforestation of natural vegetation were primarily responsible for changes in environmental quality; (b) there is a need to create public policies to preserve the natural vegetation in the watershed.

The choice Brazilian african study theme in the general education, and particularly in physical education has not advanced as to be themed with the subject matter.

Discusses with students these subjects related to corporal practices? Have difficulty in dealing with this issue? What? Thus the aim of this study was to detect whether and how a group of physical education teachers is the Brazilian african theme in their classes, for the fulfillment of the Law 10.639 / 03. The methodology of this study was qualitative descriptive type. Were used for data collection semi-structured interviews and non-participant observation. The data obtained through interviews with teachers were transcribed, reviewed and classified according to the content analysis.
