O Fetiche do Capital Intelectual: A ideologia do Conhecimento e da Adaptação no Contexto da Reestruturação Produtiva do Capital

This article presents a discussion about the fetishism of the intellectual capital, analysing the ideology of knowledge and the need of adaptation of the worker in connection with the restructuring of capital in recent decades. We analyze the emergence of this ideology - through the concepts of knowledge society, information society, intellectual capital, among others - in some authors of the area human resource management, following it presents the critique of this notion based on the analysis of some authors of critical social thought. Finally we position ourselves in order to assert that this is a new version of fetishism in the time of globalization of the capital.

Desenvolvimento de ferramentas pedagógicas para identificação de escolares de risco para a dislexia

PURPOSE: The development and application of collective pedagogical activities to assess phonological skills in pre-readers and beginning readers and could serve as potential screening tools to help in the early identification of students at risk for dyslexia. METHODS: The FAE tasks (alternative tools for educators) were built on classical phonological tasks known as sound categorization and in the Protocol for Cognitive-Linguistic Skills. FAE tasks basically consisted of matching pictures as well as pictures to spoken words according to their phonological similarity in the onset (alliteration) or rhyme and were given to 45 students on the first grade, of both genres and 7.3 years old on average. RESULTS: The protocol proved to be effective, confirming that phonological awareness, verbal working memory and rapid naming abilities constitute the main risk factors for dyslexia, and to which the FAE tasks were more strongly correlated jointly with the phonemic discrimination. FAE tasks were also strongly correlated with literacy skills. CONCLUSIONS: Students at risk for dyslexia can be efficiently identified through scientifically developed pedagogical tools, adapted and tested for the Brazilian's educational reality. This is a promising research field with the potential to help in avoiding the currently excessive number of students mistakenly labeled as having learning disabilities and improperly referred to specialized public services, as well as to indicate the more appropriate theoretical-empirical framework to guide our educational policies.

Contaminação na cidade de Caçapava, SP: exposição ao risco e investigação confirmatória

A Geografia da Saúde é um eixo temático dentro da ciência geográfica preocupada com as questões pertinentes à saúde ambiental e a saúde do coletivo. As contribuições dos geógrafos para o estudo da Saúde tem sido de grande valia, indo para além da análise espacial das práticas em saúde como também investigando e analisando os fatores determinantes ao risco a saúde e, inversamente, ao bem estar-estar do social e ambiental. Dentro deste contexto, esta monografia se propõe a uma investigação confirmatória a cerca de uma contaminação ao meio ambiente por metais pesados, neste caso, a contaminação por chumbo por uma extinta fábrica de lingotes de chumbo situada no município de Caçapava, SP. O chumbo é um metal que não possui função fisiológica conhecida ao corpo humano. Devido a características físicas e químicas favoráveis, esse metal foi largamente explorado pelo setor industrial e hoje, no mundo todo, temos exemplos de casos de contaminação tanto da população e do ambientel, por ser altamente tóxico. Caçapava possui mais um infeliz exemplo de contaminação ambiental por metais pesados, decorrente de uma fábrica que produzia o chumbo secundário e que atualmente está fechada por ordem judicial, abandonada e com toneladas de escória de chumbo armazenada de modo irregular, fato que está colaborando para uma contaminação residual naquele ambiente...

Avaliação de juntas soldadas em tubos de aço carbono submetidos a altas temperatura e pressões

The welding process in industrial piping is still the most effective way to ensure the durability and quality of the wide range of industrial process, although because of the high demand for energy and quality of the produced products, the piping has been constantly tested for high pressure applications and still high temperature. The welding method analyzed is the TIG (Tungsten Inert Gas) welding or GTAW (Gas-Shielded Tungsten Arc Welding), which ones have as principal feature the utilization of a not consumable tungsten electrode in the torch extremity , in this process is necessary a protective atmosphere of inert gas. The welding TIG advantage is the obtaining of a welded seam clean and with quality for not has slag after the welding. This work has as objective show the variability in the carbon steel piping welding parameters and by the tests in four proof bodies will be shown the influence of the variation of the welding methods in a welded seam. The tests will vary since the piece to be welded preparation, till penetrating liquid tests, welding macrography, welding x-ray and traction tests. Even been a clean and with quality welding is necessary a final inspection in the seam welded looking for defects almost inevitable resulted of the welded process, the obtained results have the objective of indicate and minimize the defects to ensure quality and durability of the welded seam

Mediadores de Centros de Ciências e os seus papéis durante as visitas escolares

In the present paper, it is presented a general view about who they are and the activities science centers and museums mediators develop. The literature points out to the diverse roles attributed to these actors and that the presence of this type of professional is a consolidated practice in non-formal educational institutions. Data obtained among the mediators of a science center during mediated school visits are also presented and discussed, focusing in the role attributed to these professionals, with the objective of characterizing their actions during these visits. The data obtained and analyzed showed that during school visits, the roles that are attributed to the mediators are: (a) mediation of the knowledge involved in the expositions; (b) explanation of the scientific concepts involved in the expositions; (c) presentation of the thematic spaces; (d) reception and organization of groups of visitors; (e) preservation of the physical and moral integrity of the visitors, and the integrity of the physical spaces and their equipments; (f) complementation of the school knowledge, and (g) diffusion of the scientific knowledge.

Trabalho e Educação: (des) emprego na Bahia

The article argues about the problematic of the technological modernization of the productive system, from years 80 and intensified in the 90, and its effect on the behavior of the labor market based in the state of the Bahia. From the few Demographic data of Census 2000 by the IBGE an analysis of the Bahia state force of work was affected mainly on the variable as employment, wage profit, race, sort and years of studies. The data show, among others questions, a labor market with a low-level of education and low wages with strong exclusion in relation to the race and sort.

Desgaste e encruamento nos aços Hadfield

O aço austenítico manganês, descoberto inicialmente por Robert Hadfield, em 1882, conhecido atualmente como aço Hadfield, continha em sua configuração inicial 12% de manganês e 1,2% de carbono. Apresentando grande resistência ao desgaste, provavelmente o maior na categoria de aciaria, ganhou rápida aceitação no mercado, sendo então propostas várias alterações em sua composição, como a introdução de vários elementos de liga, como o vanádio, molibdênio, titânio, enxofre, fósforo, cromo, níquel, entre outros. Este trabalho investigou a influência dos elementos de liga na resistência ao desgaste e no encruamento sofrido por esse material, em quatro composições que se diferenciam nos elementos de liga e em suas porcentagens. A resposta foi uma grande resistência ao desgaste da liga contendo titânio, entretanto esta não apresentou a maior profundidade de camada encruada.

O rádio na educação brasileira

The scenario that outlines this research project is characterized by the centrality of ICT on society and the necessity of having them embedded on education, both face-to-face and distance learning. Amongst the available ICT, the medium radio has been chosen due to its popularity within Brazilian society, as well as its 90 years of initiatives applied on education. Although the radio seems to be historically useful to education, it has been supporting more conservative approaches, such as teaching centred practices, simplytransmitted lessons and assessment based on memorization. On the other hand, Brazilian educational system has been changed since the early 90s, and those reforms brought new challenges to the radio on education, such as training critical listeners, concerned citizens, people with aesthetic sensibility, ethical standards etc. Thus, a systematic assessment of the real educational possibilities of the radio is even more necessary. This research projectaims to retrieve the most prominent educational initiatives using the radio, connecting them to the Brazilian regulatory framework on Education. The methodology consists of desk research and official documents analyses.
