    Hamlet observa a Horácio que há mais cousas no céu e na terra do que sonha a nossa filosofia. Era a mesma explicação que dava a bela Rita ao moço Camilo, numa sexta-feira de novembro de 1869, quando este ria dela, por ter ido na véspera consultar uma cartomante; a diferença é que o fazia por outras palavras. 
    — Ria, ria. Os homens são assim; não acreditam em nada. Pois saiba que fui, e que ela adivinhou o motivo da consulta, antes mesmo que eu lhe dissesse o que era. Apenas começou a botar as cartas, disse-me: "A senhora gosta de uma pessoa..." Confessei que sim, e então ela continuou a botar as cartas, combinou-as, e no fim declarou-me que eu tinha medo de que você me esquecesse, mas que não era verdade... 
    — Errou! Interrompeu Camilo, rindo. 
    — Não diga isso, Camilo. Se você soubesse como eu tenho andado, por sua causa. Você sabe; já lhe disse. Não ria de mim, não ria... 
    Camilo pegou-lhe nas mãos, e olhou para ela sério e fixo. Jurou que lhe queria muito, que os seus sustos pareciam de criança; em todo o caso, quando tivesse algum receio, a melhor cartomante era ele mesmo. Depois, repreendeu-a; disse-lhe que era imprudente andar por essas casas. Vilela podia sabê-lo, e depois...

    TEXT
           Roraima  also differs from other areas of the Amazon, given the timid way in which corporate capital has ventured into the region. Despite its natural riches, there are no large-scale mining or timber operations, and local industries are embryonic. Resulting from the mild stage of capitalist exploration, and relatively recent human occupation, the number and intensity of conflicts over regional resources are substantially smaller.
          Migration represented a leading role in the territorial, political and cultural formation of Roraima. During the 1970s and 1980s the state received a considerable influx of migrants from the North and Northeast regions of Brazil, especially from Ceará, Maranhão, Pará and Amazonas states. Overtime migration flows were perpetuated due to the workings of very active migrant social networks, linking very specific communities at origins and destinations. Internally, the city of Boa Vista has played a paramount role attracting immigrants from other states and then redistributing them to other municipalities. The importance of Boa Vista can be grasped from a quick examination of Roraima's urban network, where it exerts the role of a primate city in a highly unbalanced system.
             The tremendous influx of migrants over the 1970s and 1980s had a direct impact in the creation of new municipalities, promoting regional development and economic change, which, in turn, fueled renewed migratory flows. The 1990s and 2000s witnessed an augmentation of such moves projecting an inversion in terms of importance of inter and intrastate moves in future years. After all, interstate long distance moves have historically dominated Roraima's migration system; nonetheless, over the last decades intrastate migration has grown at a much faster pace than longer moves.
               In the near future Roraima is likely to continue drawing migrants from traditional areas given the organic nature of migrant social networks and its tendency to remain active over time. On the other hand, new migration flows are likely to arise and intensify as regional development will create economic opportunities for many, intensifying formal and informal communication channels. Within this context, the service sector, especially the public administration system will allure urban bound migrants from various Brazilian cities. However, one cannot deny the fact that Roraima remains an active agriculture frontier, where the perspective of acquiring a free plot of land is still viable. Thus, Roraima will still receive large waves of landless peasants in the near future, most likely from traditional source areas. Nevertheless, in order to become a valid alternative for the Brazilian poor, it is imperative that current abandonment rates within colonization projects are diminished, preventing them from turning into a demographic void, while the peripheral areas of the encroaching urban places become increasingly plagued with poverty.

    Leia o texto ‘Cresce violência nas escolas’ e responda à questão.



            Os atos de violência contra os professores têm aumentado, de maneira inquietadora, apesar das medidas tomadas pelas autoridades para coibilos, como mostram dados levantados pela reportagem do Estado nas escolas públicas e particulares de ensino fundamental e médio do Estado de São Paulo. No primeiro semestre deste ano, foram registrados nada menos do que 548 boletins de ocorrência de agressão física de alunos contra professores, o que dá uma média de três por dia.

           No caso da rede pública estadual, que conta com 5,2 mil unidades, dados da Secretaria da Educação indicam que aqueles casos de agressão subiram de 188 em 2015 para 249 em 2016. O problema não é de hoje. Resultados de um levantamento publicado em 2013 mostram que 44% dos professores da rede de ensino básico já haviam sofrido algum tipo de violência, sendo as mais comuns as verbais (39%) e as de assédio moral (10%). As de violência física não passavam de 5%, o que indica que a situação vem piorando.

         Esse problema é um grande desafio para as autoridades porque tem vários aspectos importantes a serem atacados ao mesmo tempo, tais como a quebra de disciplina e autoridade – que começa em casa –, sem as quais a escola não funciona, a desestruturação da família, as carências sociais, a falta de perspectiva profissional para os jovens, em contraste com a sedução das drogas e do tráfico, e a difusão da cultura da violência. Sem se esquecer de que esse tipo de violência não é exclusivo das regiões e populações mais carentes. 

           Em contraposição a esta situação estarrecedora, em 2009, as autoridades educacionais de São Paulo lançaram a ideia inovadora da criação da figura de um professor mediador de conflitos para promover o diálogo e melhorar as relações entre os professores e os alunos. A ideia teve o apoio do Sindicato dos Professores do Ensino Oficial do Estado de São Paulo (Apeoesp) e da Prefeitura da capital e a participação, em sua implantação, do Tribunal de Justiça. A intenção dessa iniciativa é resolver os conflitos dentro da escola, evitando que eles descambem para a violência.

          “Buscamos evitar a judicialização de conflitos. Desde criança se aprende que violência se responde com violência. E assim a justiça se tornou uma espécie de vingança”, afirma o juiz Egberto de Almeida Penido, que participa de um dos projetos desse programa, indicando o esforço que os mediadores devem fazer para matar no nascedouro o ciclo de ódio que leva à agressão.

           Um exemplo dos resultados que podem ser obtidos com a ação dos mediadores de conflitos, citado pela reportagem, é o da Escola Estadual Sérgio Murilo Raduan, no Jardim Varginha, extremo sul da capital. Ali, só no primeiro bimestre de 2016, foram registrados 46 casos de desrespeito ao professor ou funcionário por aluno e neste ano, no mesmo período, o número baixou para 12 por causa do diálogo promovido entre as partes pelos mediadores, precedido de uma calma conversa com o aluno exaltado.

          Apesar desses resultados animadores, os números que mostram o aumento das agressões deixam claro que a ação dos mediadores de conflito não é uma panaceia. Tem limites. Quando o diálogo falha e a agressão ocorre, quebrando o princípio da autoridade – além, é claro, do dano físico ou moral causado ao agredido –, o caso tem de ter desdobramentos administrativos e criminais. O agressor tem de ser responsabilizado por seus atos.

         Todos os esforços devem ser feitos, em todos os planos possíveis, para atacar o complexo problema da violência entre os jovens. Mas, ultrapassado o limite da integridade física e moral, assim como o da disciplina em sala de aula, não pode haver tolerância com a violência. O recente episódio da brutal agressão sofrida pela professora Márcia Friggi, da cidade de Indaial, em Santa Catarina – que está longe de ser um caso isolado –, vítima de um aluno de 15 anos, que já havia agredido antes a própria mãe, mostra o alto preço que sempre se paga por tolerar a impunidade, dentro ou fora das escolas.
