A social and ecological assessment of tropical land uses at multiple scales: the Sustainable Amazon Network

Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazonia Sustentavel, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers three advantages for addressing land-use sustainability problems: (i) the collection of synchronized and co-located ecological and socioeconomic data across broad gradients of past and present human use; (ii) a nested sampling design to aid comparison of ecological and socioeconomic conditions associated with different land uses across local, landscape and regional scales; and (iii) a strong engagement with a wide variety of actors and non-research institutions. Here, we elaborate on these key features, and identify the ways in which RAS can help in highlighting those problems in most urgent need of attention, and in guiding improvements in land-use sustainability in Amazonia and elsewhere in the tropics. We also discuss some of the practical lessons, limitations and realities faced during the development of the RAS initiative so far.Keywords: Social–ecological systems, Tropical forests, Land use, Interdisciplinary research, Sustainability, Trade-off

A educação de Hermes e a disciplina de filosofia na política curricular brasileira pós-década de 1990

Orientador: Prof. Dr. Geraldo Balduíno HornDissertação (mestrado) - Universidade Federal do Paraná, Setor de Educação, Programa de Pós-Graduação em Educação. Defesa : Curitiba, 05/12/2018Inclui referênciasResumo: A presente dissertação de mestrado sistematiza e problematiza o sentido e a função do ensino de Filosofia no contexto das políticas públicas educacionais a partir da publicação da LDBEN 9394/96. Identifica e analisa quais são as principais contradições existentes entre as intencionalidades expressas nas fundamentações, justificativas e concepções dos documentos oficiais e as ações que as traduzem no âmbito das instâncias político-administrativa e escolar. O estudo é realizado a partir dos pressupostos do materialismo histórico-dialético de Marx apoiando-se também e, principalmente, nos seguintes autores: KOSIK (2010); HARVEY (2017); DUARTE (2011; 2012; 2013; 2016) e SAVIANI (2008; 2012; 2013; 2016). A pesquisa mostra que as concepções utilizadas como justificativa das reformas educacionais em prol de uma suposta qualidade, ocultam a essência das relações de manutenção do poder hegemônico da sociedade capitalista e suas formas de (con)formação. Reafirma a necessidade não só da manutenção da Filosofia no Ensino Médio como também de seu tratamento didático-pedagógico que a considere como uma disciplina que possui especificidade metodológica, estatuto disciplinar próprio, conteúdos socialmente referendados, podendo contribuir com o processo de humanização e emancipação dos indivíduos.

It also identifies and analyzes which are the main contradictions between the intentions expressed in the reasons, justifications and conceptions of official documents and the resulting actions in the politicaladministrative and schools contexts. The study is developed in dialectical and historical materialism perspective of Marx, also considering, mainly, the following authors: KOSIK (2010); HARVEY (2017); DUARTE (2011; 2012; 2013; 2016) e SAVIANI (2008; 2012; 2013; 2016). The research shows that the concepts used as justification of educational reforms in favor of a so-called quality, conceal the essence of hegemonic society power in its capitalist relations and its forms of settle for it. It still reaffirms the need not only for the maintenance of Philosophy in high school as well as its didacticpedagogic treatment considering as a discipline that has methodological specificity, own bylaw status, contents socially approved, and may contribute to the process of humanization and emancipation of individuals Key-words: Education, Philosophy teaching, Curriculum, Dialectical and Historical Materialism

Measurement of the Z boson production cross-section in proton-lead collisions at sNN \sqrt{s_{\textrm{NN}}} = 8.16 TeV

This article presents the first measurement of the differential $Z$-boson production cross-section in the forward region using proton-lead collisions with the LHCb detector. The dataset was collected at a nucleon-nucleon centre-of-mass energy of $\sqrt{s_\mathrm{NN}}=8.16\,\mathrm{TeV}$ in 2016, corresponding to an integrated luminosity of $30.8\,\mathrm{nb}^{-1}$. The forward-backward ratio and the nuclear modification factors are measured together with the differential cross-section as functions of the $Z$ boson rapidity in the centre-of-mass frame, the transverse momentum of the $Z$ boson and a geometric variable $\phi^{*}$. The results are in good agreement with the predictions from nuclear parton distribution functions, providing strong constraining power at small Bjorken-$x$.This article presents the first measurement of the differential Z-boson production cross-section in the forward region using proton-lead collisions with the LHCb detector.
