The audible and the inaudible : Bob Kaufman and the politics of silence

O poeta americano Bob Kaufman fez um voto de silêncio nas décadas de sessenta e setenta do século passado. Durante quase dez anos, não falou nem escreveu. “The Audible and the Inaudible: Bob Kaufman and the Politics of Silence” (“O Audível e o Inaudível: Bob Kaufman e a Política do Silêncio”) é uma tentativa de ver o silêncio de Kaufman como uma espécie de discurso político em nome das massas anónimas, dos marginais, dos que não conseguem fazer-se ouvir. O ensaio baseia-se, em parte, na obra recente de Jacques Rancière sobre discurso e política. Para Rancière, a política só pode ser exercida através do discurso, através da participação dos que não são vistos como parte activa. No entanto, o silêncio de Kaufman é uma recusa do discurso e da participação; assim sendo, o ensaio procura explorar o silêncio como um discurso político que se mantém socialmente isolado e inaudível, mas procura, ainda assim, reconhecer todos aqueles que continuam a não ter voz nas nossas instituições democráticas.

Effect of Community of Residence on Neurobehavioral Development in Infants and Young Children in a Flower-Growing Region of Ecuador

In this study we compared neurobehavioral development in Ecuadoran children living in two communities with high potential for exposure to organophosphate (OP) and carbamate pesticides to that of children living in a community with low potential for exposure. Residence in communities with high potential for exposure to OP and carbamate pesticides was associated with poorer neurobehavioral development of the child even after controlling for major determinants of delayed development. Malnourished populations may be particularly vulnerable to neurobehavioral effects of pesticide exposure.

Groundwater residence time distributions in peatlands: implications for peat decomposition and accumulation

Peat soils consist of poorly decomposed plant detritus, preserved by low decay rates, and deep peat deposits are globally significant stores in the carbon cycle. High water tables and low soil temperatures are commonly held to be the primary reasons for low peat decay rates. However, recent studies suggest a thermodynamic limit to peat decay, whereby the slow turnover of peat soil pore water may lead to high concentrations of phenols and dissolved inorganic carbon. In sufficient concentrations, these chemicals may slow or even halt microbial respiration, providing a negative feedback to peat decay. We document the analysis of a simple, one-dimensional theoretical model of peatland pore water residence time distributions (RTDs). The model suggests that broader, thicker peatlands may be more resilient to rapid decay caused by climate change because of slow pore water turnover in deep layers. Even shallow peat deposits may also be resilient to rapid decay if rainfall rates are low. However, the model suggests that even thick peatlands may be vulnerable to rapid decay under prolonged high rainfall rates, which may act to flush pore water with fresh rainwater. We also used the model to illustrate a particular limitation of the diplotelmic (i.e., acrotelm and catotelm) model of peatland structure. Model peatlands of contrasting hydraulic structure exhibited identical water tables but contrasting RTDs. These scenarios would be treated identically by diplotelmic models, although the thermodynamic limit suggests contrasting decay regimes. We therefore conclude that the diplotelmic model be discarded in favor of model schemes that consider continuous variation in peat properties and processes.

Supramolecular materials: longer and safer gastric residence

A supramolecular polymer that is stable in the acidic environment of the stomach but dissolves in the neutral-pH environment of the intestines prolongs the safe retention of gastric devices.
