Arte, museu, educação: uma integração necessária na superação das tecnologias de controle social

This research aims to reflect on the strategies and mediation used by Oscar Niemeyer and Museum of contemporary art, in Curitiba, and Pinacoteca and Museum of modern art of São Paulo, to approximate audience of art. Recognizes that the gap between the two and that is reflected in the low visitation to art museums is the result of social control technologies historically elaborate and maintained to keep track of who has economic power over others , are people , as in the case of artistic appreciation, or countries, such as what happens with technology.It also presents some possibilities of subversion of this control , which occur especially because the human being creative and interpretive. Finally, it notes that the work carried out by the educational sectors of museums to attract different audiences is very relevant institutions and committed. With regard to teaching materials prepared and distributed to visitors, however, the need for some adjustments so that they communicate better with visitors and contribute, in fact, to deconstruct the idea of the Museum as an elite space and available only to a few privileged.

Vagabundos e criminosos: o trabalho como mecanismo de poder e índice de criminalização no discurso jurídico-penal de reinserção social dos apenados

This study was a critical investigation of the configuration of discourse on work in the Brazilian criminal legal discourse. We problematized the discourse of an alleged reintegrative social function proposed by the criminal legal system and analyzed the role of such discourse in the core of disciplinary power strategies that impose on individuals the honest worker condition as a major criterion for their rehabilitation and return to society as citizens. This critique is our starting point to build the argument that discourse on work as it appears in current criminal legal texts operates more as a criminalization index of those who do not have a lawful occupation than a guarantee of legitimate social transit for convicts and recognition of their dignity. For this purpose, we used as corpus the main sources of Law, namely the Federal Constitution of 1988, the Penal Code, the Penal Execution Law, the Brazilian criminal doctrine and an extensive, more recent penal jurisprudence with regard to techniques of resocialization through work. This critical line enabled us to recognize complexity and plurality of discourses - antagonistic, at times - that build the world of work as portrayed in legal texts. We also sought reference in the discussion on the centrality of work as a formative category of the social being as well as theories that defend the non-centrality of work. Throughout our investigation, we sough to question the very condition of such centrality and to understand the ways in which it was possible to produce a legitimating discourse on work as a model of emancipatory social conduct defended and demanded by the Brazilian punitive system. In a context of precariousness, unemployment and flexibilization of the world of work in contemporary society, convicts hardly ever succeed to resume the identity of honest, hard-working citizens - and no longer offenders. In this context, we also questioned the formulation of a discourse that speaks about human labor as the essence of man and criticizes the Marxist vision that is based on work centrality, and we approached the concept of Michel Foucault, our theoretician of reference, who understands work more as a mechanism of power that promotes the individuals’ submission and adaptation to a goods-producing society than the natural activity of man. We ascribe our study to the field of questions that tackle the political conception of the body as subject to labor imposed as productive and political force. It is about the issue of political technology of individuals, a technology of power, as named by the French author. The intended analysis has not dismissed the material existence of labor relations but sought to discuss the validity of a discourse that considers work the main resource for convict rehabilitation and index for the recognition of dignity and honesty. The Foucauldian discourse analysis was the foundation for the investigation of our object, especially if we understand discourses as social practices with power to institute knowledge and produce truths.

Representações sociais sobre educação ambiental e objetivações em práticas pedagógicas no ensino fundamental

This work presents results, reflections, conclusions and considerations about the research entitled "Social representations of environmental education and objectivations in teaching practices in elementary school ". She intended to make known research whose objectives were to know the current environmental education framework (EA) developed by the teachers of the early years of elementary school of that city; identify their social representations about EA and the ways in which these representations are objectified in their teaching practices. Thus, the methodology is characterized by the qualitative approach; whose data collection instruments were the Free Evocation Questionnaire (QEV), the semi-structured interviews and documentary research. The QEV consists of free recall questions and essay questions, whose data is quantitative and qualitative. Data from this instrument were analyzed according to the procedures of the Structural Approach to Theory of Social Representations. In turn, the analysis of data obtained through the interview and reading the documents followed the guidelines of the Content Analysis method. The theoretical and methodological basis of this research was the Theory of Social Representations and critical approach to environmental education. Thus, the results obtained in the investigation allowed us to identify the social representations of EA of participants; confirm that such representations are being targeted in their pedagogical practices that are characterized as conservative. Also confirm that the teaching documents of the surveyed network are in line with the official documents on EA; the AE actions developed in the network are referenced in the teaching documents of the network and in the official documents of EA and the EA practices of survey participants teachers relate directly with their social representations on Environmental Education.

Medidas de concentração de radônio proveniente de argamassas de cimento portland, gesso e fosfogesso

Portland cement being very common construction material has in its composition the natural gypsum. To decrease the costs of manufacturing, the cement industry is substituting the gypsum in its composition by small quantities of phosphogypsum, which is the residue generated by the production of fertilizers and consists essentially of calcium dihydrate and some impurities, such as fluoride, metals in general, and radionuclides. Currently, tons of phosphogypsum are stored in the open air near the fertilizer industries, causing contamination of the environment. The 226 Ra present in these materials, when undergoes radioactive decay, produces the 222Rn gas. This radioactive gas, when inhaled together with its decay products deposited in the lungs, produces the exposure to radiation and can be a potential cause of lung cancer. Thus, the objective of this study was to measure the concentration levels of 222Rn from cylindrical samples of Portland cement, gypsum and phosphogypsum mortar from the state of Paraná, as well as characterizer the material and estimate the radon concentration in an environment of hypothetical dwelling with walls covered by such materials. Experimental setup of 222Rn activity measurements was based on AlphaGUARD detector (Saphymo GmbH). The qualitative and quantitative analysis was performed by gamma spectrometry and EDXRF with Au and Ag targets tubes (AMPTEK), and Mo target (ARTAX) and mechanical testing with x- ray equipment (Gilardoni) and the mechanical press (EMIC). Obtained average values of radon activity from studied materials in the air of containers were of 854 ± 23 Bq/m3, 60,0 ± 7,2 Bq/m3 e 52,9 ± 5,4 Bq/m3 for Portland cement, gypsum and phosphogypsum mortar, respectively. These results extrapolated into the volume of hypothetical dwelling of 36 m3 with the walls covered by such materials were of 3366 ± 91 Bq/m3, 237 ± 28 Bq/m3 e 208 ± 21 Bq/m3for Portland cement, gypsum and phosphogypsum mortar, respectively. Considering the limit of 300 Bq/m3 established by the ICRP, it could be concluded that the use of Portland cement plaster in dwellings is not secure and requires some specific mitigation procedure. Using the results of gamma spectrometry there were calculated the values of radium equivalent activity concentrations (Raeq) for Portland cement, gypsum and phosphogypsum mortar, which were obtained equal to 78,2 ± 0,9 Bq/kg; 58,2 ± 0,9 Bq/kg e 68,2 ± 0,9 Bq/kg, respectively. All values of radium equivalent activity concentrations for studied samples are below the maximum level of 370 Bq/kg. The qualitative and quantitative analysis of EDXRF spectra obtained with studied mortar samples allowed to evaluate quantitate and the elements that constitute the material such as Ca, S, Fe, and others.
