Communicating culture: strategic communication management of the contemporary art museums in the XXIth century, in Portugal: case studies: Museu Nacional de Arte Contemporânea: Lisboa; Museu de Arte Contemporânea de Serralves, no Porto; Museu de Arte Contemporânea de Elvas

Throughout the year and half of research developed during the times of crisis or economic crisis in Portugal due to the austerity measures, this thesis focuses on the cultural communication and museology in the area of cultural management in Portugal. With an ever growing number of research being developed over the world, this study is unique as it studies managerial diversity and organisational structures of Contemporary Art Museums that exist in Portugal but more importantly how they communicate their organizations within and beyond the Museum walls such as online or other technological media. As the communication management of the museums is one of aspects of culture in which cultural management intends to intervene. The research study that I proposed to analyse has at the forefront the intention to understand how the Contemporary Art Museums in Portugal manage their communication and respective organizations, whether they be a Public-Private/Foundation, State or Council run organizations but also understand if a strategic plan is designed and implemented in times of crisis, to withstand disruptive economic scenarios projected on a daily basis. The following Museums were selected due to the fact of being Contemporary Art Museums but also their respective diverse territorial distribution, one in the city capital of Portugal, Lisbon: MNAC – Museu Nacional de Arte Contemporânea, a stately run organisation; the second, in the north of Portugal: MACS – Museu de Arte Contemporânea de Serralves, a public/private organisation under the Foundation organics and the third Museum in interior central region of Portugal, Alentejo: MACE – Museu de Arte Contemporânea de Elvas, managed by the Elvas City Council.

Chemical communication in the Mozambique tilapia: a role for amino acids

The Mozambique tilapia (Oreochromis mossambicus) is a maternal mouthbrooding cichlid from the southern Africa. The olfactory sensitivity of the species to 20 amino acids was assessed using the electro-olfactogram (EOG). We estimated whether the olfactory potency of the polar fraction of male urine can be explained by the presence of identified amino acids. In addition, filtrate and amino acid mixture of the urine of Nile tilapia were used to estimate their olfactory potency for O.mossambicus. Finally, concentrations of the main amino acids were measured in the urine of males of different social status and the correlations between amino acid concentration and hierarchical status were explored. L-cysteine, L-glutamine and L-threonine were the most potent stimuli at M while L-proline and L-aspartate were the least potent. Four groups of amino acids were identified according to their thresholds of detection and three groups – according to the similarity of their ɣ-factors. The estimated threshold of detection for O.mossambicus mixture was higher than that for the filtrate. On the contrary, the threshold of detection for the mixture of Nile tilapia was lower than that for the filtrate The concentration of L-arginine in the urine was positively correlated with fish dominance index. Both L-arginine and L-glutamic acid concentrations had much greater variability in dominant males (DI˃0.5) than in subordinate males (DI˂0.5). The urinary concentrations of L-phenylalanine had similar variability in dominant and subordinate groups. The Mozambique tilapia has olfactory sensitivity to all twenty amino acids tested. The fish showed more acute sensitivity to conspecific urine filtrate than to the heterospecific. Olfactory potency of O.mossambicus filtrate can be largely but not fully explained by the presence of L-arginine, L-glutamic acid and L-phenylalanine. Larginine and L-glutamic acid may indicate the dominance status of the fish and, possibly, individual identity.
