A partir de entrevistas realizadas a miembros del gremio de albañiles de Quito, el artículo formula algunas hipótesis sobre la formación de la cultura popular en la primera mitad del siglo xx. El gremio de albañiles se desarrolló en el contexto de una ciudad que pretendía ser moderna pero que, al mismo tiempo, reprodujo el privilegio y determinadas formas de violencia simbólica propias de una sociedad más tradicional. Frente a estas concepciones de privilegio, el estudio explora las nociones de raza popular y de respeto que emergen desde el espacio popular. Paralelamente, el artículo discute algunos problemas metodológicos y éticos relacionados con el método biográfico y con la posibilidad de escribir una historia de los trabajadores.

Chronic pesticide poisoning is difficult to detect. We sought to develop a low-cost test battery for settings such as Ecuador’s floriculture industry. First we had to develop a case definition; as with all occupational diseases a case had to have both sufficient effective dose and associated health effects. For the former, using canonical discriminant analysis, we found that adding measures of protection and overall environmental stressors to occupational category and duration of exposure was useful. For the latter, factor analysis suggested three distinct manifestations of pesticide poisoning. We then determined sensitivity and specificity of various combinations of symptoms and simple neurotoxicity tests from the Pentox questionnaire, and found that doing so increased sensitivity and specificity compared to use of acethylcholinesterase alone – the current screening standard. While sensitivity and specificity varied with different case definitions, our results support the development of a low-cost test battery for screening in such settings.
