Contribuição para a validação da escala "children's auditory processing performance scale" para a população portuguesa

A perturbação do processamento auditivo pode afectar negativamente o comportamento auditivo da criança, levando, entre outros, a um baixo rendimento escolar e a alterações do comportamento. Por este motivo é importante a identificação precoce desta perturbação. No entanto em Portugal não se encontra nenhum instrumento de medida disponível para o efeito, o que motivou este estudo. Assim sendo, este estudo tem como objectivos a tradução, adaptação cultural e validação da escala Children's Auditory Processing Performance Scale (CHAPPS) (Smoski, Brunt, & Tannahill, 1992) para o Português Europeu. Depois de traduzida e adaptada culturalmente a escala foi validada. Esta foi administrada a 154 indivíduos, dos quais 125 eram pais/encarregados de educação e 29 eram professores de crianças em idade escolar, do 1º ciclo. A versão portuguesa da escala (P-CHAPPS) apresentou uma excelente consistência interna (=0,950), estabilidade temporal e uma correlação entre as subescalas e o total com valores entre 0,581 e 0,857. As características psicométricas da P-CHAPPS revelam que esta pode ser utilizada na população portuguesa, ficando assim disponível, em Portugal um instrumento de medida a ser utilizado na identificação precoce das perturbações do processamento auditivo.

Global 2009 1km MODIS (MOD35/MOD09) cloud frequency and MOD35 processing path

Identifying cloud interference in satellite-derived data is a critical step toward developing useful remotely sensed products. Most MODIS land products use a combination of the MODIS (MOD35) cloud mask and the 'internal' cloud mask of the surface reflectance product (MOD09) to mask clouds, but there has been little discussion of how these masks differ globally. We calculated global mean cloud frequency for both products, for 2009, and found that inflated proportions of observations were flagged as cloudy in the Collection 5 MOD35 product. These erroneously categorized areas were spatially and environmentally non-random and usually occurred over high-albedo land-cover types (such as grassland and savanna) in several regions around the world. Additionally, we found that spatial variability in the processing path applied in the Collection 5 MOD35 algorithm affects the likelihood of a cloudy observation by up to 20% in some areas. These factors result in abrupt transitions in recorded cloud frequency across landcover and processing-path boundaries impeding their use for fine-scale spatially contiguous modeling applications. We show that together, these artifacts have resulted in significantly decreased and spatially biased data availability for Collection 5 MOD35-derived composite MODIS land products such as land surface temperature (MOD11) and net primary productivity (MOD17). Finally, we compare our results to mean cloud frequency in the new Collection 6 MOD35 product, and find that landcover artifacts have been reduced but not eliminated. Collection 6 thus increases data availability for some regions and land cover types in MOD35-derived products but practitioners need to consider how the remaining artifacts might affect their analysis.
