Movimentos sociais e reivindicações populares em torno das empresas de transformação mineral em Barcarena: um estudo da atuação das associações de moradores e trabalhadores rurais

A pesquisa trata da atuação dos movimentos sociais ocorridos no entorno do complexo industrial de Barcarena, após a implantação das empresas Albrás, Alunorte e Pará Pigmentos, que deram origem às associações de moradores e produtores rurais. O objetivo é a identificação dos principais movimentos surgidos e existentes, analisando-os à luz da Teoria dos Novos Movimentos Sociais. A partir de uma pesquisa exploratória, alicerçada no referencial bibliográfico, busca-se ainda verificar as vertentes pelas quais enveredaram os movimentos sociais que deram origem às entidades representativas no município. A pesquisa de campo realizou-se entre os anos de 2003 e 2004 junto a 15 associações existentes em Barcarena e que envolvem 18 comunidades rurais e urbanas, onde se aplicou questionários para verificar como estas encaminhando suas reivindicações e se relacionando com os poderes locais. Foram realizadas ainda entrevistas com técnicos das empresas e da Prefeitura e com antigos moradores. Dentre os resultados da análise de dados, pode-se afirmar há uma diferença entre as aspirações dos movimentos sociais urbanos e rurais, mas as principais reivindicações referem-se a melhoria da infraestrutura, saúde, educação e desenvolvimento agrícola. A identificação dos principais movimentos sociais em Barcarena foi um dos resultados esperados no decorrer da pesquisa, pois não se pode afirmar que exista um típico movimento social em Barcarena que faça contraponto às empresas no sentido de protesto, mas o movimento existe e é bastante ativo nos moldes dos novos movimentos sociais. Conclui-se que no enfrentamento cotidiano entre empresas e comunidades, o que prevalece é a categoria de movimento popular, onde as reivindicações coletivas voltam-se para a melhoria das condições de vida e de aspectos que envolvem seu cotidiano, além, é claro, da defesa de seu modo de produção e reprodução de vida.

Early influence of auditory stimuli on upper-limb movements in young human infants: an overview

Given that the auditory system is rather well developed at the end of the third trimester of pregnancy, it is likely that couplings between acoustics and motor activity can be integrated as early as at the beginning of postnatal life. The aim of the present mini-review was to summarize and discuss studies on early auditory-motor integration, focusing particularly on upper-limb movements (one of the most crucial means to interact with the environment) in association with auditory stimuli, to develop further understanding of their significance with regard to early infant development. Many studies have investigated the relationship between various infant behaviors (e.g., sucking, visual fixation, head turning) and auditory stimuli, and established that human infants can be observed displaying couplings between action and environmental sensory stimulation already from just after birth, clearly indicating a propensity for intentional behavior. Surprisingly few studies, however, have investigated the associations between upper-limb movements and different auditory stimuli in newborns and young infants, infants born at risk for developmental disorders/delays in particular. Findings from studies of early auditory-motor interaction support that the developing integration of sensory and motor systems is a fundamental part of the process guiding the development of goal-directed action in infancy, of great importance for continued motor, perceptual, and cognitive development. At-risk infants (e.g., those born preterm) may display increasing central auditory processing disorders, negatively affecting early sensorymotor integration, and resulting in long-term consequences on gesturing, language development, and social communication. Consequently, there is a need for more studies on such implications.

Electromyographic study of the trapezius muscle in free movements of the arm

The trapezius muscle (superior, middle and inferior portions) was analyzed in 20 volunteers. The electromyographic tests were carried out using a four-channel TECA TE 2-7 electromyograph with surface- and single coaxial needle electrodes. In abduction, adduction and flexion-extension, the 3 portions show increasing and decreasing activity, respectively, from the beginning until the end of these movements. In hyperextension, the 3 portions show increasing activity from the beginning until the end of the movement, with greater participation of the middle portion. Significant differences were not observed in the electromyographic profile of the trapezius, using surface and needle electrodes.

Electromyographic study of the trapezius muscle in free movements of the shoulder

The objective of this study is to analyze the simultaneity of the actions of the three portions of the trapezius (superior portion = TS; middle portion = TM and inferior portion = TI) in elevation, lowering, retraction and protraction of the shoulders. The electromyographic tests were carried out in 20 volunteers using a 4-channel TECA TE 2-7 electromyograph and surface and single coaxial needle electrodes. The electromyographs, obtained with the two types of electrodes, show that in elevation and lowering of the shoulders, TS and TM present increasing and decreasing activity, respectively, from the beginning until the end of these movements. In retraction of the shoulders, TM and TI present increasing activity from the beginning to the end of the movement. In protraction, TS, TM and TI do not show any activity.

Evaluation of the relationship between education and sustainability in peasant movements: The experience of the National Education Program in Agrarian Reform

Brazil is one of the largest agricultural producers in the world. However, its agrarian composition is based on two markedly different production models, particularly in relation to sustainability: a peasant family agriculture, which plays an important role in food production for domestic consumption and advocates agro-ecological practises; and agribusiness, the politically and economically hegemonic model that produces commodities for export based on monoculture and intensive use of pesticides. Therefore, in order to create the means to develop peasant lands, social movements and peasants have engaged themselves politically and defended an education model grounded in sustainable practises of production and social organisation. Taking this into account, the main purpose of this paper is to analyse and assess the Brazilian experience of integration between education and sustainability, in the National Education Program in Agrarian Reform (PRONERA). To accomplish this aim, a survey with a semi-structured questionnaire was carried out among teachers, students, monitors, and coordinators of the course offered by PRONERA. The surveys showed that the courses are promoting the concepts of sustainability among peasants. However, many adjustments need to be taken into consideration during the planning process for the next courses offered by PRONERA.

Saccadic and smooth pursuit eye movements attenuate postural sway similarly

Effects of saccadic eye movements on postural control in older adults

Saccadic eye movements have been shown to affect posture by decreasing the magnitude of body sway in young adults. However, there is no evidence of how the search for visual information that occurs during eye movements affects postural control in older adults. The purpose of the present study was to determine the influence of saccadic eye movements on postural control in older adults while they stood on 2 different bases of support. Twelve older adults stood upright in 70-s trials under 2 stance conditions (wide and narrow) and 3 gaze conditions (fixation, saccadic eye movements at 0.5 Hz, and saccadic eye movements at 1.1 Hz). Head and trunk sway amplitude and mean sway frequency were measured in both the anterior/posterior (AP) and medial/lateral (ML) directions. The results showed that the amplitude of body sway was reduced during saccades compared with fixation, as previously observed in young adults. However, older adults exhibited similar sway amplitude and frequency in the AP direction under the wide and narrow stance conditions, which is different from observations in young adults, who display larger sway in a narrow stance compared with a wide stance while performing saccades. These results suggest that although older adults are affected by saccadic eye movements by a decrease in the amplitude of body sway, as observed in young adults, they present a more rigid postural control strategy that does not allow larger sway during a more challenging stance condition.
