Variação da área irrigada por pivôs centrais no Brasil entre 2013 e 2014.

Foram comparadas as áreas irrigadas por pivôs centrais no Brasil em 2013 e 2014, mapeadas através da identificação visual a partir de mosaicos formados por imagens do satélite Landsat 8 ? OLI / TRS de 2013 e 2014, respectivamente, exibidas no programa Google Earth. Em 2013 foram identificados 17.878 pivôs centrais, ocupando uma área irrigada de 1.179.176 ha. Em 2014, foi observado aumento de 11% no número de pivôs centrais e de 8% na área irrigada (19.928 pivôs centrais, 1.279.072 ha irrigados). Em 2013, praticamente 90% dos pivôs concentravam-se nos Estados de Minas Gerais, São Paulo, Goiás, Bahia e Rio Grande do Sul, situação também observada para o ano de 2014. Em alguns Estados foi verificado aumento maior do que 20% no número de pivôs entre 2013 e 2014, como em Alagoas (133%), Santa Catarina (50%), Mato Grosso (20,07%). Em outros Estados, porém, o número de pivôs diminuiu em mais do que 20%, como é o caso do Sergipe (-100%), Pernambuco (-75%) e Maranhão (-46,61%). Em 2013, aproximadamente 45% dos pivôs centrais do Brasil concentrava-se na Região Hidrográfica do Rio Paraná; e quase 30%, na do Rio São Francisco. Em 2014, a Região Hidrográfica do Rio Paraná passou a concentrar cerca de 50% dos pivôs centrais do país. Apesar das adversidades climáticas verificadas nos últimos anos, principalmente nas áreas de Cerrado, com o aumento de incentivos econômicos para a produção de alimentos prevê-se a expansão futura das áreas irrigadas no país. Apesar do benefício potencial da irrigação para a produção agrícola, estratégias para promover o aumento da produção agrícola irrigada devem considerar restrições relacionadas com a disponibilidade, qualidade e conflitos de uso da água das bacias hidrográficas em que estão inseridas. Ações estimulando a melhoria da qualidade da água, conservação de nascentes e áreas de preservação permanente, bem como o gerenciamento eficiente dos recursos hídricos, contribuirão para a melhoria da qualidade e quantidade de água disponível, fundamentais para possibilitar a sustentabilidade e expansão futura da agricultura irrigada no Brasil.

Velocidade da moeda, inflação e ciclos de negócios no Brasil, 1900-2013

A presente tese é composta por três ensaios. O primeiro ensaio estuda os ciclos de negócios brasileiro no período dos anos 1900 até 2012. Uma série trimestral do PIB real é elaborada, utilizando um modelo estrutural de séries de tempo. A partir disso, um modelo com mudança Markoviana é proposto para que seja construída uma cronologia de ciclo de negócios. O modelo selecionado possui dois regimes distintos, cenários de expansão e de recessão, a datação obtida é comparada com outros estudos sobre o tema e são propostas caracterizações das fases de crescimento que podem apoiar estudos sobre a história econômica do Brasil. O segundo ensaio estuda o comportamento da velocidade da moeda no ciclo de negócios brasileiro de 1900 até 2013. Os resultados a partir das estimativas dos modelos de séries temporais, MS e GARCH, são utilizados para suportar esse estudo. Em termos gerais a velocidade da moeda no Brasil apresentou queda até a segunda Guerra Mundial, cresceu até meados dos anos 1990 e a partir disso segue em tendência de queda. A experiência inflacionária brasileira é capítulo importante de nossa história econômica. O objetivo do terceiro ensaio é estudar a volatilidade da inflação brasileira ao longo do tempo no período de 1939 até 2013, buscando descrever sua relação com a taxa de inflação, adotando como referência uma datação de ciclos de negócios. Para realizar essa descrição serão utilizados os resultados obtidos nas estimações de modelos econométricos das classes GARCH, BSM e MS. No caso brasileiro a indicação é que a taxa de inflação impacta positivamente sua volatilidade.

A "voz das ruas" e a rearticulação da ideologia conservadora

The aim of this paper is to analyze the street demonstrations occurred last June and July 2013, which appear as samples of the hegemonic fights in course in Brazil, during the so-called Big Wave of the social groups in conflict nowadays in the country. Among other questions, this study tries to explain how the varied stages of these fighting groups influenced their late ones. For that, it takes into consideration the bibliography available not only on these groups, but also on the social and political contemporary Brazil. That is why it evaluates political documents, as well as opinion pieces, news and others disseminated by the press or by political groups. Speeches made by political leaderships, as, for example, that one the President Dilma Roussef made on 21 July 2013, deserves close analysis. This also applies to contributions made by secondary data, poll institutions and IBGE’s socio-economic data. Categories and concepts of Antonio Gramsci’s political sociology are used here as theoretic bases. In fact, it favors the hypothesis that, during the dispute for the intellectual and moral command of demonstrations on July 2013, a certain middle-class conservative ideology emerged on scene. This group conquered the agreement of hegemonic mass media acting now as a political party, here designated as media party. These media resorted to platforms preexistent to the demonstration movements, especially their rejection to political organizations and programs in order to ascend as the demonstrations’ leaders along a certain period in which corruption appeared as the central theme of these efforts, while the government tried to get control of the situation. In view of the several forces and issues at stake, the present study contributes to the discussion about the current reality in Brazil and its perspectives, without losing sight of the centrality of the June Movements as political and ideological milestones

Leitura do mundo no rap: uma análise bakhtiniana de práticas leitoras no ensino fundamental

This study aims to propose two didactic sequences on the rap songs to the process of formation of critical reflective reader, in the elementary school – in 6th and 9th grade classes. The theoretical foundations that have supported the work are related to the Bakhtin Circle propositions, especially the notions of language as a social ideological discourse; responsive reading; discursive genre and social voices. As for the methodological guidance, it is characterized by adopting the interpretativist paradigm of socio-historical base, in addition to positioning in the large field of Applied Linguistics, whose primary focus is specifically located language. In the selected enunciations to corpus – some Rap songs of protesting – it was analyzed the students’ reflective critical reading in the workshops of Rap-song reading, applied in modules of our teaching sequences. Through the carried out analysis, it was noted that the subjects surveyed have come from an educational culture towards the fulfillment of a conteudista proposed curriculum, so that in this scenario we do not see, through reading, training of the individual citizen, able to through his readings, understanding the socio-ideological structure that surrounds them; and so, escaping of understandings the world, based only on common sense. We conclude also that our teaching proposal represented a novelty for students. Initially, some of them did not see this work as reading, however, the majority was heavily involved in the process; so that, in their comments, we realize voices of a critical and reflective look of which comprise environments, and social situation to which they belong.

Conversações políticas no youtube: junho de 2013 e circulação de sentidos nos comentários do vídeo “globo e os protestos”

This re search analyzes the talks dynamics about policy established in YouTube symbolic space. We are interested in examining the way in which the commentators of the video " Globo e os Protestos " articulated in the field intended for comments, a public space directed to the dissemination and circulation of meanings about policy issues. The video studied was published by PC Siqueira and Diego Quint eiro , during the June 2013 protests in Br azil, to direct the political understanding of the movement lived in that period. According to them, the protests had left political position and therefore the protesters should reject the coverage by TV Globo (a comunication vehicle with ideals of right) and allow the participation of political parties linked to the ideological left spectrum. This narrative generated empathy and controversy betwe en commentators, which produced in the comments, an intense argumentative process about these theses (right and left). To understand the phenomenon, we conducted an exploratory qualitative research, the main methodological procedure was a ethnomethodological discourse analysis. We seek the observation of the ways in which the commentators es tablished talks about politics in the comments space, for, thereafter , organize categories of analysis based on identified discursive recurrences. The empirical reflections are supported from discussions about the YouTube potential, while digital media com prising massive strategies and while articulating space in the engagement of individuals in political issues; also confront the aspects involved in the conversation practices that results in sociability dynamics and , especially , in conflict, on the socio - t echnical networks; and finally, we propose a reflection about the circuit actuation in which the people take ownership and realize new readings about the products received. Concluding that the use of digital media , such as YouTube, has caused significant c hanges in the forms of production and reception of symbolic products and ways in which people participate in political issues concerning life in society.

Policiais não sabem como conter protestos violentos

A pesquisa sobre a percepção dos policiais a respeito dos manifestantes e do movimento black bloc, produzida pela Diretoria de Análise de Políticas Públicas (DAPP- FGV ) e obtida pelo GLOBO, fez um raio X do que pensam os policiais sobre os protestos, os black blocs e sua própria forma de agir diante deles. Foram feitas 5.304 entrevistas, sendo 4.499 com policiais militares e 805 com policiais civis de todas as regiões do país. O levantamento foi realizado pela internet, a partir de um cadastro que reúne nomes desses profissionais de todo o Brasil, entre 26 de novembro de 2013 e 14 de janeiro deste ano.
