Late quaternary dynamics in the Madeira river basin, southern Amazonia (Brazil), as revealed by paleomorphological analysis
Authors: Hayakawa Ericson H. , Rossetti Dilce F.
Published: March 2015

Ancient drainage systems are being increasingly documented in the Amazon basin and their characterization is crucial for reconstructing fluvial evolution in this area. Fluvial morphologies, including elongate belts, are well preserved along the Madeira River. Digital Elevation Model from the Shuttle Radar Topography Mission favored the detection of these features even where they are covered by dense rainforest. These paleomorphologies are attributed to the shifting position of past tributaries of the Madeira River through avulsions. These radial paleodrainage networks produced fan-shaped morphologies that resemble distributary megafans. Distinguishing avulsive tributary systems from distributary megafans in the sedimentary record is challenging. Madeira´s paleodrainage reveals the superposition of tributary channels formed by multiple avulsions within a given time period, rather than downstream bifurcation of coexisting channels. Channel avulsion in this Amazonian area during the late Quaternary is related to tectonics due to features as: (i) straight lineaments coincident with fault directions; (ii) northeastward tilting of the terrain with Quaternary strata; and (iii) several drainage anomalies, including frequent orthogonal drainage inflections. These characteristics altogether lead to propose that the radial paleodrainage present at the Madeira River margin results from successive avulsions of tributary channels over time due to tectonics.

This paper is a floristic and phytosociological study of the dry forest communities of the Dominican Republic. A total of 69 relevés in dry forest biotopes were carried out. The samples were subsequently subjected to Detrended Correspondence Analysis for the determination and study of possible groupings. The study does not cover tree formations growing on serpentines, nor the so-called semideciduous forests, peculiar to areas with higher rainfall. A total of nine phytocoenoses were identified. The most significant results led to the description of six new phytosociological associations: Simaroubetum berteroani(thorny dry forest on coastal dunes), Phyllostylo rhamnoidis-Prosopidetum juliflorae (southern Dominican disturbed dry forest), Consoleo moniliformis-Camerarietum linearifoliae(dry forest on hard limestones), Lemaireocereo hystricis-Prosopidetum juliflorae(northern Dominican disturbed dry forest), Lycio americani-Prosopidetum juliflorae (disturbed dry forest on saline soils) and Guettardo ellipticae-Guapiretum discoloris (dry forest on flat-topped hillocks in Montecristi). This is an important step forward in the phytosociological and floristic studies of the Caribbean territories.

Published: March 2015

In this work, we used the Minimum Inhibitory Concentration (MIC) technique to evaluate the antibacterial potential of the apitoxin produced by Apis mellifera bees against the causative agents of tooth decay. Apitoxin was assayed in naturaand in the commercially available form. The antibacterial actions of the main components of this apitoxin, phospholipase A2, and melittin were also assessed, alone and in combination. The following bacteria were tested: Streptococcus salivarius, S. sobrinus, S. mutans, S. mitis, S. sanguinis, Lactobacillus casei, and Enterococcus faecalis. The MIC results obtained for the commercially available apitoxin and for the apitoxin in natura were close and lay between 20 and 40µg / mL, which indicated good antibacterial activity. Melittin was the most active component in apitoxin; it displayed very promising MIC values, from 4 to 40µg / mL. Phospholipase A2 presented MIC values higher than 400µg / mL. Association of mellitin with phospholipase A2 yielded MIC values ranging between 6 and 80µg / mL. Considering that tooth decay affects people's health, apitoxin and its component melittin have potential application against oral pathogens.

Authors: Oliveira Olga M.M.F. , Brunetti Iguatemy L. , Khalil Najeh M.
Published: March 2015

In this study, the effect of nicotine on the LDL oxidation by the MPO/H2O2/Cl- system and the effect of HOCl on LDL and some of its components, such as methyl linoleate, vitamin E and the amino acid tryptophan were explored. Nicotine, in micromolar concentrations, enhanced the tryptophan oxidation, either present in LDL or free, in solution. Nicotine also decreased the formation of conjugated dienes and oxygen consumption in a methyl linoleate / HOCl system, and there was evidence to suggest an increase in chlorohydrin formation. Acceleration of the vitamin E oxidation by HOCl was also observed in the presence of nicotine. These data show that the interaction of nicotine and HOCl can promote significant biochemical modifications in LDL particle and some of its components involved in the pathogenesis of cardiovascular and other diseases.

Published: March 2015

This study aimed to investigate if an executive functions (EF) intervention could promote these skills in individuals with attention deficit and hyperactivity disorder (ADHD). Eighteen children and adolescents, 7-13 years old, divided into experimental (EG, N = 8) and control (CG, N = 10) groups, were assessed in the Block Design and Vocabulary subtests of the WISC III and seven tests of EF. Parents answered two scales, measuring EF and inattention and hyperactivity signs. EG children participated in a program to promote EF in twice-weekly group sessions of one hour each. After 8 months of intervention, groups were assessed again. ANCOVA, controlling for age, intelligence quotient and pretest performance, revealed gains in attention/inhibition and auditory working memory measures for the EG. No effect was found for scales or measures of more complex EF. Results are not conclusive, but they illustrate some promising data about EF interventions in children and adolescents with ADHD.

Published: March 2015

Objective To compare performance of children with attention deficit hyperactivity disorders-combined (ADHD-C) type with control children in multi-source interference task (MSIT) evaluated by means of error related negativity (ERN). Method We studied 12 children with ADHD-C type with a median age of 7 years, control children were age- and gender-matched. Children performed MSIT and simultaneous recording of ERN. Results We found no differences in MSIT parameters among groups. We found no differences in ERN variables between groups. We found a significant association of ERN amplitude with MSIT in children with ADHD-C type. Some correlation went in positive direction (frequency of hits and MSIT amplitude), and others in negative direction (frequency of errors and RT in MSIT). Conclusion Children with ADHD-C type exhibited a significant association between ERN amplitude with MSIT. These results underline participation of a cingulo-fronto-parietal network and could help in the comprehension of pathophysiological mechanisms of ADHD.

Published: March 2015

Neurodegenerative diseases represent a heterogeneous group of neurological conditions primarily involving dementia, motor neuron disease and movement disorders. They are mostly related to different pathophysiological processes, notably in family forms in which the clinical and genetic heterogeneity are lush. In the last decade, much knowledge has been acumulated about the genetics of neurodegenerative diseases, making it essential in cases of motor neuron disease and frontotemporal dementia the repeat expansions of C9orf72 gene. This review analyzes the main clinical, radiological and genetic aspects of the phenotypes related to the hexanucleotide repeat expansions (GGGGCC) of C9orf72 gene. Future studies will aim to further characterize the neuropsychological, imaging and pathological aspects of the extra-motor features of motor neuron disease, and will help to provide a new classification system that is both clinically and biologically relevant.

Objective: The present study was aimed at evaluating the viability of replacing 18F with 99mTc in dose calibrator linearity testing. Materials and Methods: The test was performed with sources of 99mTc (62 GBq) and 18F (12 GBq) whose activities were measured up to values lower than 1 MBq. Ratios and deviations between experimental and theoretical 99mTc and 18F sources activities were calculated and subsequently compared. Results: Mean deviations between experimental and theoretical 99mTc and 18F sources activities were 0.56 (± 1.79)% and 0.92 (± 1.19)%, respectively. The mean ratio between activities indicated by the device for the 99mTc source as measured with the equipment pre-calibrated to measure 99mTc and 18F was 3.42 (± 0.06), and for the 18F source this ratio was 3.39 (± 0.05), values considered constant over the measurement time. Conclusion: The results of the linearity test using 99mTc were compatible with those obtained with the 18F source, indicating the viability of utilizing both radioisotopes in dose calibrator linearity testing. Such information in association with the high potential of radiation exposure and costs involved in 18F acquisition suggest 99mTc as the element of choice to perform dose calibrator linearity tests in centers that use 18F, without any detriment to the procedure as well as to the quality of the nuclear medicine service.

Objetivou-se comparar um modelo multi-característica padrão com modelos de análise de fatores (AF) e de componentes principais (CP) para estimar parâmetros genéticos para a produção de leite no dia do controle (PLDC) de vacas da raça Holandesa. O arquivo de trabalho constituiu-se de 4.616 registros mensais de PLDC de primeiras lactações de vacas da raça Holandesa. As PLDC foram agrupadas em dez classes mensais, entre o 5o e 305o dia da lactação (PLDC1 a PLDC10). Foram realizadas análises considerando 11 modelos diferentes, como segue: multi-característica padrão (MC); cinco modelos de posto reduzido, para a matriz de covariância genética, ajustando um a cinco (CP1 ... CP5) componentes principais; e dois modelos utilizando análise de fatores (F1, F2, F3, F4 e F5). Para todos os modelos, foram considerados como aleatórios os efeitos genético aditivo e o residual e como fixos os de grupo de contemporâneos, da idade da vaca ao parto (linear e quadrático) e dias em lactação (linear). Os valores de Log L, AIC e BIC melhoraram com o aumento do número de parâmetros até CP4 e AF4. Comparando CP4 e AF4, observa-se que CP4 resultou em melhores valores de Log L, AIC e BIC. As estimativas de herdabilidade e correlações genéticas utilizando os modelos MC, CP4 e AF4 foram similares, variando de 0,06 (PL6) a 0,65 (PL10) e de 0,05 (PL4xPL10) a 0,94 (PL2xPL3), respectivamente, indicando que a estrutura de covariâncias genéticas entre as produções de leite no dia do controle pode ser ajustada utilizando um modelo de posto reduzido, contendo quatro componentes principais ou quatro fatores

OBJECTIVE: To analyze the association between the length of napping during the night shift and the recovery after work among nurses.METHOD: Cross-sectional epidemiological study involving 1940 nurses from 18 public hospitals in the City of Rio de Janeiro. A multidimensional and self-applied questionnaire was used with information about health, sociodemographic and occupational characteristics, health-related behaviors and housework. Multiple logistic regression was applied to identify the association, adjusted for confounding variables.RESULTS: The gross analyses showed 44%, 127% and 66% higher chances of a high level of recovery after work for nurses who sleep up to two hours, between 2.1 and 3 hours and 3.1 hours or more, respectively, when compared to the nurses who do not sleep. After adjusting for confounding variables, the association only continues significant for the group that sleeps 2.1 to 3 hours during the night shift (OR=1.79; 95%CI=1.33-2.41).CONCLUSION: The association between the length of napping and the high level of recovery after work, confirmed in the present results, can be included in the studies that aim to support more appropriate policies aimed at improving the workers' work, life and health conditions, not only in nursing, but night-shift workers in general.

The Minas-Rio Project is the biggest project from Anglo American in the world and considers Vertimill in the regrinding circuit to adequate the particle size distribution to feed slurry pipeline that will pump the ore from Conceição do Mato Dentro in Minas Gerais State to Acu Port in Rio de Janeiro State, Brazil. A Vertimill pilot test campaign was carried out at Metso's pilot plant facility located in York city, Pennsylvania State, USA, to provided information to sizing the industrial grinding circuit. The main objective of this work is proposing a way to simulate the industrial Vertimill using the population balance model, normally used to simulate ball mills. The simulations were based on the selection and breakage functions determined from the laboratory tests using a batch ball mill. The simulations were performed using a Vertimill model implemented in the ModsimTM plant-wide simulator. The results of simulations shows that was possible to simulate the pilot tests, with good accuracy, considering simple laboratory tests with small quantities of samples.

Authors: Parolin Radael de Souza , Borges Pedro Augusto Pereira , Specht Luciano Pivoto
Published: March 2015

To obtain information about pavement structure, nowadays, destructive prospecting is carried out, interfering significantly with traffic. Proposed here in is a less destructive and invasive technique, whereby a thermal probe with temperature sensors is installed in the pavement. This process identifies the sources of heat to obtain the temperature distribution as a function of time and space at different depths; to solve the heat transfer problem in two dimensions and to estimate the thickness and thermal materials properties of each layer through the Inverse Problem. The Direct Problem has been modeled by a heat conduction equation and solved by Central Finite Differences, using the explicit method of time advancements. The Genetic and Memetic Algorithms have been efficient in estimating the thickness of the layers and they have presented little difference between the estimated values at each application. The proposed technique has been efficient in estimating the thickness in the tests with experimental pavements and it brings a new perspective for structural evaluation, with reduced pavement intervention and traffic interference.

Published: March 2015

The dewatering stage is among the most important industrial unit operations, and is widely adopted in many different industries. Nowadays, mineral processing tailings disposal is a big problem due to the environmental degradation it causes. The phosphate rock processing in Anglo American Phosphate Brazil, situated in Catalão/ Go/Brazil, generates around 180 t/h of tailings for a plant feed of 480 t/h (approximately 37.5% of the processing plant feed), with 5 to 10% of solids and approximately 14% of P2O5. Nowadays, the tailings are sent directly to the tailings dam. The present work proposes paste production using the tailings from the phosphate rock processing plant. Through decantation of a tailings sample, a clarified liquid was obtained and drained. The decanted pulp then went through a second stage consisting of vacuum filtration. Flocculant addition in this stage generated a faster sedimentation rate and a higher dewatering performance in next stage of dewatering, because the flocculated material was retained by the filter medium instead of passing through it. The results were satisfactory for paste tailings production with a solid percentage of around 65%.
Proposal of an environmental sustainability index for open-pit mines using landscape fragmentation indicators
Authors: Silva Felipe Vargas E , Peroni Rodrigo
Published: March 2015

The perception of the environmental impacts caused by economic activities is subjective and usually negatively affects the image of an extractive sector such as mining. In order to avoid this, the environmental impact assessment must be supported by clear and well-selected environmental indicators. An index of sustainability was created to demonstrate that open-pit mining is comparable to other economic activities. The index is composed by of environmental indicators like water and energy consumption combined with an indicator of landscape fragmentation, using remote sensing data and geoprocessing. A comparative study considering a ten-year period was carried out with the biggest iron ore mine in Brazil, N5W, and the largest Brazilian soybean producer, the Sorriso County, in the Mato Grosso State to illustrate the methodology.

A religiosidade é uma variável importante para a pesquisa em saúde, considerando suas conhecidas associações com o processo saúde-doença e questões importantes sobre o bem-estar, atitudes, práticas e satisfação em relação a cuidados e serviços. No entanto, na pesquisa em Saúde Coletiva, é frequentemente usada a afiliação religiosa como única dimensão da religiosidade. O presente estudo objetivou investigar a adequação do uso do instrumento Duke Religious Index (DUREL) no âmbito da pesquisa em Saúde Coletiva, ao avaliar as capacidades psicométricas do instrumento quando aplicado a uma população representativa de usuários dos serviços de atenção primária à saúde de um município de porte médio do interior do Estado de São Paulo. Foi encontrada uma adequada consistência interna para o instrumento e validade convergente-discriminante. Os resultados sugerem que o uso do DUREL não é restrito à pesquisa em saúde mental e que sua utilização pode trazer novas perspectivas para o entendimento de eventos de interesse na área da Saúde Coletiva.
A ordem regional no Oriente Médio 15 anos após os atentados de 11 de Setembro
Authors: Zahreddine Danny , Teixeira Rodrigo Corrêa
Published: March 2015

O artigo aborda a ordem regional do Oriente Médio 15 anos após os atentados de 11 de setembro de 2001, analisando a relevância das potências regionais para o equilíbrio de poder naquela região. A pergunta a ser respondida é se os atentados de 11 de setembro alteraram de maneira significativa a ordem regional. O objetivo da pesquisa é avaliar o papel das potências regionais para as relações de poder no Oriente Médio e suas transformações após os atentados. Para tanto, serão apresentados os conceitos de poder, ordem e potência regional, bem como uma breve descrição das transformações ocorridas nas relações internacionais do Oriente Médio desde as independências locais até o pós-11 de Setembro. Para categorizar os Estados como potência média, emergente ou regional será utilizado a perspectiva teórica tratada por Nolte (2010), Jordaan (2010) e Huelsz (2009). Para avaliar a distribuição de poder entre os principais atores estatais, bem como sua hierarquia de poder, utiliza-se os conceitos de poder real, potencial e ideacional. São aplicadas técnicas como a Análise de Componentes Principais (ACP), para analisar os períodos de 1980, 1990, 2001 (ano dos atentados) e 2011 (dados mais recentes das fontes consultadas). Os resultados demonstram que as principais forças regionais que historicamente atuaram na região continuam presentes, e que a ordem regional vigente é semelhante à do início da década de 1990, sendo que as principais transformações se deram no campo ideacional em função do aumento da ação de forças transnacionais.
CONTROLES DE CAPITAL: 70 ANOS DE VAI E VEM
Authors: Salama Bruno Meyerhof
Published: March 2015

Este texto descreve a evolução do Direito Monetário Internacional, atinente aos controles de capitais, desde a edição do Acordo de Bretton Woods até os dias atuais. A empreitada é relevante tanto por suprir uma lacuna importante na bibliografia jurídica brasileira, quanto por causa da recente retomada por parte de diversos governos na utilização de controles de capitais.
O BRASIL E O FMI DESDE BRETTON WOODS: 70 ANOS DE HISTÓRIA
Authors: Almeida Paulo Roberto de
Published: March 2015

O objetivo deste ensaio histórico é o de acompanhar o relacionamento do Brasil com o FMI, no contexto da evolução do sistema monetário internacional, desde Bretton Woods até a atualidade. O ensaio começa por retraçar o itinerário do FMI, com destaque para a mudança de padrão cambial em 1971, e segue com o exame das relações entre o Brasil e a instituição, com ênfase nos acordos contraídos sob diferentes políticas econômicas e em momentos diversos de crises nas transações externas; o primeiro acordo foi rompido por razões políticas em 1958, e o mais recente, de 2003, foi suspenso em 2005, antes de sua conclusão, também por motivos políticos. São destacados os problemas enfrentados pelo FMI no período – estabilidade cambial, liquidez, monitoramento das economias nacionais – e as circunstâncias que levaram o Brasil a contrair seus muitos acordos com a instituição. O País manteve uma relação errática com o FMI, com aproximações e distanciamentos ao longo do período, oscilando entre uma postura cooperativa – no início e durante a maior parte do regime militar, bem como no final dos anos 1990 e início do novo milênio –, e uma outra de rejeição ou confrontação – no governo Kubitschek e na redemocratização –, finalizando por uma passagem da situação de devedor dependente, na maior parte desse longo período, a uma de credor e demandante por reformas na instituição, na fase recente, quando o País busca aumentar seu poder de voto nas instituições de Bretton Woods; uma tabela final lista os acordos concluídos pelo Brasil com o FMI e os valores envolvidos em cada um.
DEMOCRACIA Y FINANCIACIÓN DE LOS PARTIDOS POLÍTICOS EN ESPAÑA
Authors: Castro David Almagro
Published: March 2015

El presente artículo aborda un tema elemental para el correcto funcionamiento de los partidos políticos: el financiamiento de su actividad. Tras 35 años de democracia española, y varias leyes en materia de financiación de partidos, los grandes males diagnosticados por la Ciencia Política y el Derecho persisten: la financiación irregular, corrupción, falta de transparencia y publicidades lógicas en democracia. La ineficiencia legislativa en materia de financiación justifica una reflexión que persiga los siguientes objetivos interrelacionados: contextualización sobre la relevancia que el financiamiento partidario tiene en la estabilidad funcional de la democracia; análisis sobre la conformación legal del modelo español de financiamiento, con especial énfasis en la vigente Ley Orgánica n. 8, de 4 de julio de 2007 (LO 8/2007); denuncia sobre la persistencia de los viejos males así como la nueva oportunidad perdida en la mejora del financiamiento, transparencia y control de los partidos tras la reciente reforma legal.
LA CONSTITUCIONALIZACIÓN DE LOS DERECHOS DE LOS CONSUMIDORES CON ESPECIAL REFERENCIA AL ORDENAMIENTO JURÍDICO CHILENO
Authors: Soto Erika M. Isler
Published: March 2015

El presente documento se refiere al fenómeno de la constitucionalización de los derechos de los consumidores. Con tal objeto, se comienza exponiendo el grado de reconocimiento que existe en Constituciones Comparadas de las garantías de los usuarios. Posteriormente, se revisa el sistema constitucional chileno y se sostiene que de sus disposiciones sí es posible inferir la protección del sujeto más débil de la relación de consumo, aún cuando no se lo mencione de manera expresa. En el mismo sentido, se citan las propuestas de reforma constitucional que han existido en nuestro país al respecto.
“MUTAÇÃO À BRASILEIRA”: UMA ANÁLISE EMPÍRICA DO ART. 52, X, DA CONSTITUIÇÃO
Authors: Santos Carlos Victor Nascimento dos
Published: March 2015

O objetivo do presente estudo é testar a plausibilidade da tese de que teria ocorrido mutação constitucional no sistema de controle de constitucionalidade no Brasil, especificamente quanto à competência conferida pela Constituição ao Senado Federal para suspender a eficácia de lei ou ato normativo declarado inconstitucional no controle difuso de constitucionalidade. Esse argumento foi empregado pelo Ministro Gilmar Mendes, do Supremo Tribunal Federal, no julgamento da Reclamação 4.335-5/AC. Para analisar a consistência dessa tese, realizou-se uma análise empírica do papel do Senado Federal diante do art. 52, X, da Constituição. Como resultado, defende-se não ser possível dar plausibilidade a esse tipo de argumentação apenas tendo por base jurisprudência, doutrina e argumentação tipicamente constitucional, necessitando de base empírica que o permita atribuir mais solidez e consistência a qualquer argumento de mutação constitucional na ordem jurídica brasileira.
DOIS LADOS DA MESMA MOEDA: O TEMPO NO STF
Authors: Haddad Carlos Henrique Borlido , Quaresma Lucas Bacelette Otto
Published: March 2015

O artigo situa-se no Direito Processual Penal e consiste em pesquisa empírica com objetivo de identificar os critérios utilizados pelo STF para distinguir o excesso de prazo na formação da culpa da razoável duração do processo. Examinaram-se 229 acórdãos proferidos em julgamentos de habeas corpus nos anos de 1991/1992, 2001/2002 e 2011/2012 e foram selecionados aqueles em que era possível identificar a duração da prisão provisória. Foi notado aumento do prazo da prisão provisória ao longo dos anos, mas se constatou que o tempo não é o principal fator para separar prazo razoável do excesso de prazo. A gravidade da infração e a complexidade do processo pesam como critérios preponderantes. O STF não adota limites temporais precisos para reconhecer o excesso de prazo e a análise mostra-se casuística a ponto de processos mais longos serem classificados como de duração razoável.
Contribuições da antropologia para o campo da educação em saúde no Brasil
Authors: Dias João Vinícius dos Santos , Ferreira Jaqueline
Published: March 2015

O objetivo deste artigo é resgatar aspectos relativos à constituição da educação em saúde como campo científico. Mostra as principais transformações ocorridas desde as concepções autoritárias e etnocêntricas em relação a seus gruposalvo até as atuais propostas de educação popular de valorização do saber popular, inspiradas no pensamento de Paulo Freire. Defende que a postura do antropólogo em campo, ao buscar valorizar o saber do Outro como tão legítimo quanto o acadêmico, pode auxiliar os profissionais de saúde na prática de uma educação em saúde dialógica, para os grupos aos quais se destina.
Percepções e demandas de nutricionistas da alimentação escolar sobre sua formação
Authors: Honório Andréa Riskala Franco , Batista Sylvia Helena
Published: March 2015

A pesquisa teve por objetivo conhecer as percepções e demandas dos nutricionistas atuantes na alimentação escolar sobre sua formação nessa área da nutrição. A investigação foi realizada por meio de aplicação de questionário autopreenchível a 39 participantes de uma capacitação para nutricionistas que atuam no Programa Nacional de Alimentação Escolar em 2008. Os dados foram analisados mediante a utilização de abordagem qualitativa. A maioria considerou que a graduação não preparou adequadamente para a atuação na área, já que temas pertinentes ao Programa Nacional de Alimentação Escolar não são, ou são pouco abordados. Apesar das dificuldades e queixas, a maioria manifestou satisfação com sua prática na alimentação escolar, porém pressupõe ser necessária alguma mudança, tendo demonstrado desconforto com a própria prática. Este estudo reforça a importância de ampla discussão sobre a formação do nutricionista e a adequação dos currículos às demandas atuais.
O proeja e a proposta de integração curricular: dispositivos analisadores da educação
Authors: Amado Luiz Antonio Saléh
Published: March 2015

O artigo desenvolve a ideia de que o currículo integrado e a educação de jovens e adultos, associados no Programa Nacional de Integração da Educação Profissional com a Educação Básica na Modalidade de Educação de Jovens e Adultos, funcionam como analisadores, evidenciando o modo como a educação se constitui e torna possível o surgimento de outras formas de organização do fazer pedagógico. A proposta de integração curricular contida nesse programa possibilita colocar em discussão o modo como a educação tem organizado suas relações, suas práticas, seus tempos e seus espaços. Permite, ainda, ultrapassar os discursos que reafirmam a necessidade de adaptação dos projetos pedagógicos da educação 'regular' às especificidades do aluno da educação de jovens e adultos, questionando outras modalidades da educação. Além de problematizar o potencial transformador do currículo integrado, o texto analisa as reações e os movimentos suscitados nos embates entre o instituído e o instituinte, os quais podem tanto intensificar quanto reduzir a propriedade crítica da proposta, procurando torná-la equivalente às formas sociais já existentes. Conclui destacando que a educação, ao mesmo tempo em que deve ao modo como a sociedade se estrutura as suas condições de possibilidade, contribui para a produção de subjetividades que circulam nessa mesma sociedade .
