Economics knowledge, attitudes and experience of student teachers in Scotland

There is a move away from teaching economics as a separate subject in Scotland. It is now mainly taught within Business Management courses in upper secondary school and is embedded within several subject areas in both primary and early secondary curricula, a move that is in step with broader curricular aims to break down barriers among subjects. This writing discusses the need for clearly situated teaching and learning of economics, provided by teachers provided by teachers who have sufficient background knowledge to devise effective contexts for learning, whether or not it is taught as a discrete subject. The results of a survey of student teachers' levels of economic literacy are analysed and recommendations made for the preparation of teachers to deal effectively with embedded approaches to teaching about economics

La enseñanza de las ciencias sociales en la formación docente : más allá del texto escrito, el aporte de los lenguajes artísticos

A partir de la Ley Nacional de Educación del año 2006 que extendió la obligatoriedad de la enseñanza al nivel medio, nuevos sectores sociales accedieron a la escuela secundaria. Algunos de los que egresaron, pudieron iniciar carreras de Formación Docente. Lograr el aprendizaje de estos nuevos alumnos planteó un desafío para todos los profesores, entre ellos, los de Ciencias Sociales. Justamente, este trabajo tiene como objetivo compartir algunas reflexiones sobre una experiencia educativa realizada en el marco de una investigación que recibió un subsidio del INFD. El proyecto, “Más allá del texto escrito: la potencialidad de diversos objetos culturales en la formación de docentes", planteaba explorar las potencialidades didácticas de los objetos culturales para la enseñanza de las ciencias sociales, en un contexto de desigualdad y de diversidad cultural. Específicamente, para la investigación se seleccionaron solo los objetos artísticos.Fil: Pipkin, Diana . Universidad de Buenos Aire

Chemical determinants of occupational hypersensitivity pneumonitis

Background: Workplace inhalational exposures to low molecular weight (LMW) chemicals cause hypersensitivity pneumonitis (HP) as well as the more common manifestation of respiratory hypersensitivity, occupational asthma (OA). Aims: To explore whether chemical causation of HP is associated with different structural and physico-chemical determinants from OA. Methods: Chemical causes of human cases of HP and OA were identified from searches of peer-reviewed literature up to the end of 2011. Each chemical was categorised according to whether or not it had been the attributed cause of at least one case of HP. The predicted asthma hazard was determined for each chemical using a previously developed quantitative structure-activity relationship (QSAR) model. The chemicals in both sets were independently and ‘blindly’ analysed by an expert in mechanistic chemistry for a qualitative prediction of protein cross-linking potential and determination of lipophilicity (log Kow). Results: Ten HP causing chemicals were identified and had a higher median QSAR predicted asthma hazard than the control group of 101 OA causing chemicals (p < 0.005). Nine of ten HP causing chemicals were predicted to be protein cross-linkers compared to 24/92 controls (p<0.0001). The distributions of log Kow indicated higher values for the HP list (median 3.47) compared to controls (median 0.81) (p < 0.05). Conclusion: These findings suggest that chemicals capable of causing HP tend to have higher predicted asthma hazard, are more lipophilic and are more likely to be protein cross-linkers than those causing OA.
