Mídia radical: análise comparativa entre a opinião da grande imprensa e da mídia radical no novo código florestal

The objective of this work is to compare how manifests the ideological positioning in the hegemonic media productions, according to Gramsci's conception, in relation to the radical alternative media, proposed by John Downing. The research has as opinionated content sample printed newspaper O Estado de s. Paulo, contrasting with the expressions of NON-PROFIT bauruense environmental “Instituto Ambiental Vidágua on the proposals of the new Brazilian forest Code. The analysis will hold in an interval between the adoption of the code by the Chamber of deputies in April 2012, and the provisional measure of President Dilma Rousseff with 32 modifications, after vetoing 12 articles proposed initially in may 2012. To support the study, will be crafted Gramsci hegemony; What is the alternative and radical media as it manifests itself; the relationship between the environmental journalism with the environmental NGOs; opinionated journalism and journalistic genres opinionated; theories of journalism and framing of matter

Reposição florestal obrigatória no município de Presidente Venceslau

The growing concern over deforestation of native forests from Brazil to the marketing of wood in various sectors had made greater attention from lawmakers. In this context, did the reforestation, which came into existence to meet the demand for forest raw material. This paper attempts to make a survey, focusing on the interplay between small and medium producers, consumers of forest products and reforestation associations. For this, we conducted a survey of legislation at the federal and state since the emergence, evolution and current context for understanding the legal basis on the subject. In addition, literature reviews have been made seeking to direct the concepts and importance of reforestation, reforestation, forest plantations and productive use of the species Eucalyptus sp for the supply of forest raw material. Approach was also sought on the structure of the system of reforestation of the state of Sao Paulo and their assignments. We also present an in loco study of Chairman Wenceslas municipality in order to analyze the participation of the municipality in the reforest the region of Pontal Paranapanema and actions of regulatory agencies. As a result presents a survey of consumers of timber enterprises in the municipality of President Wenceslas based on the resolution SMA No. 082/2008, which describes the characteristics of these companies and their fields of activity

Experimentação e educação ambiental: contribuições metodológicas

During the last centuries, the human being have been considered the center of the universe. The man believed that nature was at his disposal. Appropriated their processes, their cycles changed, redefined their spaces. Today, when faced with an environmental crisis which threatens the planet life, including the human life, the Science Education can contribute to a reconstruction of man-nature relationship in other terms. The transformation of teaching practices in the school environment, to be reflective, it is still a process that challenges the vast majority of teachers. As has been indicated by Guerra (2004), among others, the traditional teaching of content delivery is still very strong and certainly more deeply embedded in ideas and activities of the teachers who focus on environmental education. With it, a theory and pedagogical discourses in critical-reflexive actions is still a major obstacle. Therefore, new proposals for education and continuing education activities need to be formulated and presented based on the characteristics and needs breathing. Therefore propose changes in the way of teaching, where there is more room for a theory and praxis alone or with a only scientific truth. The scenery of society requires that knowledge is constructed to interconnect all disciplines, joining theory and practice so we can understand the whole and their relations in an integrated manner. It was proposed here a way to build a school and applying theoretical and practical activities involving experimental and seeking to meet the principles of Environmental Education for the training of citizens aware and critical. At the same time cares to use textbooks very rich in its pedagogical character that are present in schools and often are, forgotten and unused by teachers. From this way, I chose to Experimentoteca, ...(Complete abstract click electronic access below)

Biodiversidade e código florestal em Botucatu, um estudo de caso

The brazilian legislation has sufored changes by the law no 1876/99, without the scientific community consultation, causing grave consequences for the country natural patrimony. The goal of this research is to investigate what the professors and students community of a São Paulo University know about the theme, as much as a rural and urban portion of persons; what they consider important and which atributes are taken in consideration. By the elaboration of closed questionnaires, qualitative and quantitative datas were collected, organized and analysed. The datas showed a low schooling by the countrified people, which reflected the low forest law knowledge. The distance between the university and society was also noticed, which indicates the lack of extension activities, ethical commitment against knowledge, technology and the sustainable development of the country. Due to, highlight the importance of extension activities towards the university, community and a knowledge future of all

Efeitos da experimentação no cotidiano letivo no ensino médio

In this work, it was studied the effects of the experimentation in the physics teaching. Beginning from the theoretic reference and discussions, the objective was prove the efficiency of researches of this nature related to two main aspects of a class: The aroused interest in the students and the facilitating action on the understanding of the theory. For such objective, using the comparison, it was chosen two distinct classes, but the more similar possible, so that, in one of them, it was showed a tradition class, lectures and in another, a class using experimentation to contemplate the theory. To manage a way to rate these aspects, it was made a conceptual questionnaire, requiring only concepts rather than mathematics and equations, besides specific interviews to rate the opinion of the student related to each method. The observations in classes and of the reactions of the students also were of a big value to analysis. After the experimental class completed, it may analyze and conclude some positive points related to experimental methods: As for the opinion of the students, the approval was big, and the majority opined to this class as being “more interesting”. On the point of view of learning, it had a sensitive improvement of grades, but with more mature answers, deep and autonomous, if looking at a general vision

Simulação de produção de sedimentos em microbacias em função de cenários de restauração florestal

In São Paulo state, deforestation and agriculture activities are increasing soil losses processes, especially in areas of susceptible soils where properties not adopt soil conservation practices. Environmental adequacy at property level regarding Permanent Protection Areas and Legal Reserves is considered a factor on reducing soil losses and considering that we assessed soil losses of different scenario of environmental adequacy. Simulations of erosive process were carried out in 15 catchments of Corumbataí river basin, according to different forest restoration scenarios, as well as the current situation of land use/land cover. The scenarios include the implementation of Permanent Preservation Areas (PPA), the reforestation of variable source areas, and two scenarios, the Legal Reserve installation in 20% of each catchment, being one of them for most critical areas in terms of erosion and the other at random. It was observed that the establishment of PPA and the reforestation of hydrologically sensitive areas, offered only a small contribution to the control of the erosive process, resulting in a reduction of 10% and 7,8%, respectively, while the legal reserve in critical areas has a significant reduction of 69,8%. The random scenario, in turn, resulted in a reduction of only 21,4%. Results show that reforestation could reduce soil losses, but previous studies of land prioritization and planning could increase significantly its efficiency at this process.

Frugivoria e dispersão de sementes por anta (Tapirus terrestris) em uma área de plantio florestal no cerrado, MS

A anta brasileira Tapirus terrestris é o maior mamífero terrestre neotropical, sendo encontrada em todos os biomas brasileiros, com exceção da Caatinga, onde foi extinta. É capaz de carregar sementes de tamanhos variados por longas distâncias e em grandes quantidades, e depositá-las em locais distantes da plantamãe. Porém, seu potencial como dispersora é questionado, uma vez que o transporte para latrinas pode dificultar o estabelecimento pela grande quantidade de sementes. Os objetivos desse projeto foram (1) investigar a dieta da anta em um ambiente de Cerrado e (2) verificar, através de testes de germinação, se a passagem pelo seu trato digestivo modifica a taxa de germinação de araçá-docampo (Psidium guineense) e mutambo (Guazuma ulmifolia). O estudo foi realizado na fazenda Barra do Moeda, Três Lagoas/MS, onde a matriz é composta por talhões de eucalipto e cerrado em diversos estágios sucessionais. Os bolos fecais foram coletados em viagens trimestrais e, na triagem, tiveram as sementes separadas e contabilizadas. Foram utilizados os testes qui-quadrado e o de Mann-Whitney para as análises estatísticas. A triagem dos bolos fecais registrou 53 espécies vegetais, sendo 31 identificadas. As famílias com maior proporção foram Myrtaceae, Poaceae, Malvaceae e Rubiaceae, sendo verificada diferença significativa na dieta entre as duas estações. O fruto de Araçá-do-Campo (Psidium guineense) foi o mais consumido nos dois períodos, o que indica a importância desse item alimentar para a anta. Além disso, foi verificada uma redução significativa no sucesso germinativo do araçá-do-campo após a passagem pelo trato digestivo desse mamífero, sugerindo que apesar da grande quantidade de sementes, parte é inviabilizada. Foram também registradas sete espécies e dois gêneros novos, o que indica a importância da realização de novas pesquisas, com o intuito... (Resumo completo, clicar acesso eletrônico abaixo)

Levantamento e análise de estudos de restauração florestal em áreas degradadas no estado de São Paulo

A preocupação com a conservação da cobertura vegetal, já há algumas décadas, tem sido objeto de amplos debates no meio científico, bem como a eficácia dos projetos de reflorestamento com espécies nativas, no estado de São Paulo, considerando-se o contexto histórico sobre questões envolvendo legislação, planejamento e análise de parâmetros ambientais, tendo-se como meta a produção de reflorestamentos de qualidade, procurando garantir a conservação da biodiversidade e a sustentabilidade das florestas implantadas. O presente estudo teve como objetivo a compilação de trabalhos pertinentes à recuperação florestal de áreas degradadas no estado de São Paulo, relatando os modelos implementados, bem como a sua efetividade, no processo de enriquecimento e manutenção da paisagem. Foi dado destaque para as práticas adotadas no processo de restauração da cobertura florestal, sendo agregados comentários respectivos aos componentes do ambiente físico, a estrutura da comunidade vegetal, bem como aos grupos sucessionais de espécies introduzidos. Para isso, foi realizado um levantamento bibliográfico da literatura produzida nos últimos 15 anos (1999-2013), envolvendo o tema em questão e divulgada em veículos técnico/científicos, tais como as publicadas em anais, sites, periódicos nacionais e internacionais, relatórios técnicos, bem como aquelas apresentadas em eventos científicos. Os resultados apontam para a necessidade da integração entre aspectos teóricos e práticos e o estabelecimento de parâmetros de avaliação e monitoramento que sejam capazes de verificar verdadeiramente a qualidade dos reflorestamentos heterogêneos

Como os pesquisadores da UNESP-Botucatu concebem a ética na experimentação animal? Consciência ou obediência?: subtitulo

Atualmente existe um consenso de que os pesquisadores estão mais conscientes em relação ao trato com as cobaias e com o bem estar animal, ao mesmo tempo, sabe-se que os comitês de ética recentes estão intensificando a fiscalização dos laboratórios. Há também leis a respeito do trato com os animais utilizados para experimentação que conta com penas, como multas em dinheiro até a exoneração do cargo de cientista e pesquisador. Investigaram-se os pesquisadores, através de um questionário, se estão mais conscientes acerca do bem estar animal ou apenas se adéquam as diretrizes dos comitês de ética para que seu projeto seja aprovado. Além de notarmos diferenças significativas entre os pesquisadores anteriores e posteriores a Lei 11.794/08 que instituiu os comitês de ética. Tendo os mais novos uma sistematização maior no trato com as cobaias enquanto os antigos repensaram suas formas de pesquisa. Quanto ao bem estar animal, nota-se que apenas se adequaram às leis, e que caso as mesmas não houvessem sido criadas não fariam alterações em seus laboratórios

Experimentação no ensino de física: um estudo escolas estaduais na região de São José dos Campos

This work presents the results of a study on the use of experimentation in physics teaching, presenting a survey on the use of this strategy in public high schools in the region of São José dos Campos. Data collection was carried out in schools by means of questionnaires prepared for physics teachers and students from three grades of high school. Data were obtained in eighteen schools distributed in the city of São José dos Campos (two in the central region, in the west, three on the east side, seven in the north and five in the south), a school in the district of Sao Francisco Xavier and a school in the town of Monteiro Lobato. Thus, data from 20 schools, 610 students and 20 teachers were analyzed. Among the main results, we highlight that over 80% of the students said that there is no physics lab at the school where they study, and less than 1% declares that uses laboratory weekly. We note that there is a laboratory in 25% of the schools in the northern region and 10% or less of the other schools. According to the students the proposition of the experimental activities by teachers is rare - only three schools in East Side the options sometimes and always exceeded the number of responses experimental activities are never proposed. We had 60% of the teachers who reported using the curriculum of the state of São Paulo to propose activities to students, and half of the teachers said they did not have classes experimental physics classes in initial training or had them in sufficient quantity to support the use of this feature in practice
