A trágica sustentabilidade em um mundo sem transcendência

As autoras discutem a questão da sustentabilidade a partir da reportagem de um casamento realizado na Avenida Paulista e definido como ecologicamente correto. Elas demonstram como esse acontecimento está contido numa escala mais ampla. Argumentam que a racionalidade capitalista presente na lógica da competitividade e do desperdício é a mesma no comando do ideário da sustentabilidade do movimento ambientalista. Munidas de um conjunto de dados referentes à ação de grupos legais e ilegais, mostram como a prática da sustentabilidade abre novas e lucrativas frentes de acumulação enquanto contribui para o agravamento dos danos irreversíveis ao meio-ambiente. Concluem que, além da impossibilidade do modelo capitalista deter o atual processo de destruição das condições de vida no planeta, somente a associação internacional dos movimentos sociais emancipadores poderá criar ações para uma radical mudança de rumo.

TERRITORIAL DISPUTES, LABOUR RELATIONS and ENVIRONMENTAL HEALTH IN AGROHIDRONEGOCIO sugarcane IN THE PONTAL PARANAPANEMA (SP)

This research aims to analyze the conflict over land in Postal do Paranapanema (state of São Paulo, Brazil), considering the competition for water resources and the degradation of environmental health in the area called the agrohidronegocio sugarcane. The survey results indicate that the expansion of sugarcane cultivation in this region is causing the worsening health of workers. Moreover, the research also seeks to identify alternative models to the hegemonic project of regional development based on matrix agrohidroenergetica. For this, the research has as interlocutors various types of social movements such as the Landless Workers Movement and the Movement of Dam Affected, and union leaders.

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.
