There are roughly two processing systems: (1) very fast gist vision of entire scenes, completely bottom-up and data driven, and (2) Focus-of-Attention (FoA) with sequential screening of specific image regions and objects. The latter system has to be sequential because unnormalised input objects must be matched against normalised templates of canonical object views stored in memory, which involves dynamic routing of features in the visual pathways.

Saliency maps determine the likelihood that we focus on interesting areas of scenes or images. These maps can be built using several low-level image features, one of which having a particular relevance: colour. In this paper we present a new computational model, based only on colour features, which provides a sound basis for saliency maps for static images and video, plus region segregation and cues for local gist vision.

The grooved carpet shell clam, Ruditapes decussatus (L. 1758), is one of the most popular and profitable molluscs exploited in rearing plots in the Mediterranean. However, annual catch has been declining steadily since the early nineties. In order to understand the seasonality of its nutritional value, thus providing an improved basis for economical valuation of the resource, gross biochemical composition, percentage edibility and condition index were investigated during a year with monthly periodicity in a commercially exploited population of the clam Ruditapes decussatus in the Ria Formosa, a temperate mesotidal coastal lagoon located in the south of Portugal. Our results show that total and non-protein nitrogen co-varied during the year, resulting in a protein content that peaked in the warmest months. Although complementary in summer, carbohydrate and lipid contents showed irregular annual trends. The observed seasonality was comparable to that shown by studies elsewhere at similar latitudes, and are underpinned by the reproductive cycle of the species. Our results show the clams to be at their prime nutritional value at the beginning of summer, when protein content peaks.

When and why did the Portuguese become the shortest Europeans? In order to find the answer to this question, we trace the trend in Portuguese living standards from the 1720s until recent times. We find that during the early nineteenth century average height in Portugal did not differ significantly from average height in most other European countries, but that when, around 1850, European anthropometric values began to climb sharply, Portugal's did not. In a panel analysis of 12 countries, we find that delay in human-capital formation was the chief factor hindering any improvement in the biological standard of living in Portugal.

O presente estudo consiste numa análise da cultura política no início do Liberalismo em Portugal, centrada sobre os deputados micaelenses nas Cortes Portuguesas que emergiram da revolução liberal de 1820 e, por outro lado, numa revisitação da revolução de 1821 em Ponta Delgada. Nesse contexto, a proposta de projecto apresentada por um dos deputados que visava a abolição dos vínculos na ilha de São Miguel e nos Açores foi o mote para esta dissertação. Visitamos a conjuntura de outro espaço atlântico na mesma época, a Madeira, de modo a conduzirmos uma avaliação comparativa, mantendo o quadro atlântico em perspectiva. Recorremos, por fim, à biografia de um deputado para obtermos uma escala de observação mais próxima da dinâmica política.
