Reading hybrid texts : remarks on text/image transitions

The reading of printed materials implies the visual processing of information originated in two distinct semiotic systems. The rapid identification of redundancy, complementation or contradiction rhetoric strategies between the two information types may be crucial for an adequate interpretation of bimodal materials. Hybrid texts (verbal and visual) are particular instances of bimodal materials, where the redundant information is often neglected while the complementary and the contradictory ones are essential.Studies using the 504 ASL eye-tracking system while reading either additive or exhibiting captions (Baptista, 2009) revealed fixations on the verbal material and transitions between the written and the pictorial in a much higher number and duration than the initially foreseen as necessary to read the verbal text. We therefore hypothesized that confirmation strategies of the written information are taking place, by using information available in the other semiotic system.Such eye-gaze patterns obtained from denotative texts and pictures seem to contradict some of the scarce existing data on visual processing of texts and images, namely cartoons (Carroll, Young and Guertain, 1992), descriptive captions (Hegarty, 1992 a and b), and advertising images with descriptive and explanatory texts (cf. Rayner and Rotello, 2001, who refer to a previous reading of the whole text before looking at the image, or even Rayner, Miller and Rotello, 2008 who refer to an earlier and longer look at the picture) and seem to consolidate findings of Radach et al. (2003) on systematic transitions between text and image.By framing interest areas in the printed pictorial material of non redundant hybrid texts, we have identified the specific areas where transitions take place after fixations in the verbal text. The way those transitions are processed brings a new interest to further research.

Caracterização das infeções do trato urinário de origem microbiana : casuística de um Hospital Veterinário de Lisboa

As infeções do trato urinário (ITU’s) são doenças infeciosas frequentes na prática clínica veterinária, sendo fundamental uma correta antibioterapia, principalmente pelo crescente desenvolvimento de resistências bacterianas aos antibióticos. Realizou-se um estudo retrospetivo, englobando 86 animais admitidos no Hospital Veterinário do Restelo, submetidos a urocultura, com o objetivo de caracterizar as ITU’s microbianas neste hospital, avaliando a sua epidemiologia e suscetibilidade antibiótica das bactérias isoladas. Da totalidade das uroculturas realizadas (n=86), 28 foram positivas, 18 em canídeos e 10 em felídeos, sem predisposição racial, mais em fêmeas nos canídeos e em machos nos felídeos. A idade média dos animais com ITU foi 8 anos nos canídeos e 10 anos nos felídeos. Todas as ITU´s foram monobacterianas, sendo o microorganismo mais frequentemente isolado a Escherichia coli. Verificou-se multirresistência em 10 das 28 bactérias isoladas. A gentamicina foi o antibiótico com melhor perfil de sensibilidade global e o que apresentou mais resistências foi a tetraciclina. O antibiótico mais prescrito de forma empírica foi a enrofloxacina. Este estudo,especialmente se realizado de forma periódica, poderá ser um contributo para a elaboração de guias institucionais de antibioterapia adequada e minimização do aparecimento de resistências bacterianas.

New source-material for the socio-economic history of the Hindus of Goa

The Mhamai brothers were the suppliers of daily commodities / stationery to the viceroys / governors of Goa. Since late 18th century their agency house worked in partnership with several other trading houses all over the west coast of India. They also served as brokers for the French East India company in Goa during the critical period of anglo-french wars. The Mhamais were also revenue farmers, particularly customs and tobacco tax farming. I had the privilege of taking their family archives to the Xavier Centre of Historical Research in 1979 and making the history of the family known worldwide.
