Este trabalho pretende colaborar na discussão sobre a responsabilidade da televisão pública na educação ambiental. Para tanto examina o programa Repórter Eco com a finalidade de investigar as regularidades e convenções presentes na abordagem da temática ecológica. Com base nos críticos da mídia e em autores preocupados com os aspectos políticos do discurso ambientalista, como Leff e Latour, busca-se repensar a função educativa da televisão pública no país em relação ao meio ambiente.

Background: The prevalence of motor delays (MD) in schoolchildren is an intercultural phenomenon which is particularly present among socio-economically disadvantaged children. Objective: to describe and explain the proximal processes for the development of fundamental motor skills (FMS) in schoolchildren from an elementary school (ES) in a coastal city in the Northeast of Brazil. the objective of this study was to describe and explain the proximal processes for the development of fundamental motor skills (FMS) in schoolchildren from an elementary school (ES) in a coastal city in the Northeast of Brazil. Methods: This was a quali-quantitative study. The quantitative aspect was characterized by the use of the Test of Gross Motor Development Edition 2 to evaluate the fundamental motor skills of 104 children from 7 to 10 years old, 56 boys (8.2±1.0 years) and 48 girls (8.3 ± 0.9 years). Regarding the qualitative aspect, the researcher ecologically placed himself in the context and used non-systematic and non-participant observations and interviews with 7 parents, representing the parents-board of the school, 7 Physical Education teachers and 11 classroom teachers from different schools. Data analysis: the qualitative data were organized using the content analysis synthesis. The quantitative data were treated using descriptive statistics (mean, standard deviation, distribution and frequencies) and inferential statistics (Student t-test). Results: The results revealed that 95.1% of children present MD in locomotor skills and 81.7% in object control skills; girls showed poorer performance compared to boys (p < 0.001). Considering the Bioecological model the MD can be explained by the absence of physical infrastructures and material resources, lack of opportunities and poor teacher training. However, the main explanation was the absence of a pedagogical program to foster MP in schools and youth sports programs. Yet, the Bioecological model allowed us to establish that the MP interferes the way that children interact with the context. Conclusions: It can be inferred that part of the solution to the problem lies in the coordination of exosystem actions (Municipal Department of Education) and in changes to the macrosystem (educational legislation) which guarantee the microsystems (schools and social sports projects) the means to promote MP in children.

This article addresses the issue of social conflict from the epistemology of "deep disagreements". Unlike other types of disagreements, deep ones generate incommensurability and cannot be corrected through rational argumentation, precisely because it can amplify the disagreement and exacerbate the problem. At the base of these divergences lie two irreconcilable epistemological positions: infallibilism and fallibilism. The infallibilist style of argumentation is embodied in attempts to find objective truth through final and conclusive evidence. Such a position induces them to defend their own beliefs through vicious cycles that Carlos Pereda has called "argumentative vertigos", generating different silencing and devaluation strategies based on identity prejudices (a kind of "grievance" that, in Miranda's words Fricker, constitutes an act of "epistemic injustice"). Dizzying argumentation can even lead to an epistemic annihilation of the Other as a valid interlocutor. This phenomenon is presented as "epistemicide" (adapted from the Portuguese sociologist Boaventura de Sousa Santos). In this work, the analysis of the frictions, tensions and disputes that can be activated in the course of the production and validation of knowledge is taken further, to probe the conditions under which devaluation and annihilation may be perpetrated against himself. I call this phenomenon "autoepistemicide", and I draw a comparison between this concept and its concomitant in the clinical setting: that of "Gaslighting". Finally, I extract the most important reflections of the article, opening new horizons for future research.

Ilus. Tab. Bib. Sum. (En) ; Secondary forests developing on agricultural land after it is abandoned, or as the fallow period in systems of subsistence agriculture, are an increasingly important component of the forest resources of the tropics. They fix and store carbon and may contribute to the alleviation of global warming, they are refuges for biodiversity in agricultural landscapes, and they are low-cost sources of a tremendous variety of forest products. The final years of the 20th century represent an opportune time to bring together researchers concerned with biological, ecological, social/organizational, financial/economic and political aspects of secondary forests and their management, to share their experiences and opinions concerning secondary tropical forests and to contribute to the development of a forward-looking, cross-disciplinary research agenda. The conference had the following objectives: 1) to summarize the state of knowledge of tropical secondary forests from the standpoint of the ecological, social and political sciences. 2) to report the most recent results of research on secondary forests from all relevant disciplines.

O presente artigo discute a inserção do Brasil no mercado mundial de alumínio a partir dos referenciais teóricos da ecologia política, da economia política do território e da saúde coletiva. A conjuntura contemporânea da economia mundial tem sido pautada pela desregulamentação e liberalização, característicos do ideário neoliberal propalado pelas nações centrais. A maior participação do Brasil nesse mercado tem sido realizada a partir do aumento da produção e exportação de commodities agrárias e metálicas, como o alumínio. Nesse sentido, a partir dos paradigmas da ecologia política, o texto propõe uma análise das consequências socioambientais, assim como sobre novas territorialidades que se produzem e reproduzem dentro de uma lógica econômica que privilegia as nações centrais. Do mesmo modo, procura-se compreender os dilemas da saúde coletiva sob uma perspectiva holística e integradora na qual se articula aos modelos de desenvolvimento econômico. Percebe-se que a produção e exportação de alumínio primário, apesar de apresentar um valor agregado maior, esconde um conjunto difuso de impactos que afetam o ambiente e a saúde coletiva. ; This article discusses the inclusion of Brazil in the global aluminum market from the theoretical framework of political ecology, political economy of the territory and collective health. The contemporary situation of world economy has been marked by deregulation and liberalization, characteristic of neoliberal ideals touted by the core nations. Brazil's larger share in this market has been held from the increased production and export of agricultural commodities and metals, like aluminum. In this sense, from the paradigms of political ecology, the paper proposes an analysis of social and environmental consequences, as well as of new territoriality that is produced and reproduced within a logic that privileges the economic core nations. Similarly, we seek to understand the dilemmas of collective health in a holistic and integrative perspective in which economic development models are articulated. It is noticed that the production and export of primary aluminum, despite having a greater aggregate value, hides a diffuse set of impacts that affect the environment and public health.

O artigo analisa as pesquisas científicas realizadas no Instituto Agronômico do Norte (IAN), instituição criada pela política desenvolvimentista do governo brasileiro para a utilização agrícola da Amazônia nas décadas de 1940 e 1950. Discutimos especialmente as pesquisas relacionadas à chamada "teoria do ecossistema florestal", desenvolvida pelo limnologista alemão Harald Sioli na instituição. A teoria orientou a agenda de pesquisa do IAN naquelas décadas: policultura, construção de canais de colmatagem no rio Amazonas, aproveitamento de áreas de várzea para a produção de alimentos, e o desenvolvimento da bubalinocultura nas terras firmes da região. O IAN projetava a Amazônia como celeiro do mundo e solução para a fome planetária. O principal instrumento dessa transformação seria o conhecimento de sua ecologia. ; This article addresses scientific research conducted at the Agronomic Institute of the North (IAN), an institution created under the Brazilian government's developmentalist policy to promote the agricultural use of the Amazon in the 1940s and 1950s. We place special emphasis on the research related to the so-called "forest ecosystem theory", developed at the institute by the German limnologist Harald Sioli, which guided the following institutional research agenda during those decades: polyculture, the excavation of siltation channels along the Amazon river, the cultivation of food crops, and the buffalo ranching. The IAN projected the Amazon to be the breadbasket of the world and a solution to world hunger. The main instrument of this transformation would be the knowledge of its ecology.

There exists a universal ecology-based stratification of levels of activity and meaning-making in human societies, a stratifying architecture that determines existing levels of social experience, types of sign functions and semantic functions in language, and finally the mental principles of human subjectivity. The planetary ecology of civilization is therefore constitutive of human semiotics. The following is a short outline of a theory of meaning based on these observations.
