Um Portugal de imigrantes: exercício de reflexão sobre a diversidade cultural e as políticas de integração

Apesar da pluriculturalidade que caracteriza algumas regiões de Portugal, existe um desconhecimento e por vezes resistência, em particular das comunidades mais tradicionais e das gerações mais antigas, na aceitação dos imigrantes que escolhem o nosso País como destino de acolhimento. Conhecer as comunidades imigrantes pode ajudar a perceber e a minimizar as dificuldades do convívio pluricultural. Este será, na atualidade, um dos papéis que o animador sociocultural será chamado a desempenhar. Para isso, é necessário que reconheça os recursos legais, metodológicos e teóricos que tem ao seu dispor, sendo estas as premissas que norteiam o presente exercício. Esta análise nasceu de uma proposta de trabalho da Unidade Curricular de Multiculturalidade e Cidadania, mas rapidamente se revelou um importante contributo para o conhecimento da diversidade cultural no nosso país. Após uma contextualização teórica relativa aos principais fluxos migratórios em Portugal, é apresentada a análise dos dados relativos à composição das origens dos imigrantes em Portugal na atualidade e a sua distribuição pelo território português. Este é o ponto de partidapara a reflexão que se lhe seguiu, que visa, por um lado, identificar algumas das problemáticas que resultam dos contextos de diversidade cultural e, por outro, conhecer as propostas do Estado para promover a integração do “outro”. Estes pilares sustentaram a abordagem final relativa ao papel da Animação Sociocultural (ASC) e do animador neste contexto.

Liderança virtuosa, comprometimento organizacional e desempenho individual

Num mundo hipercompetitivo, a afirmação da virtuosidade tem enfrentado consideráveis resistências, sendo mesmo considerada como sinónimo de fraqueza ou ingenuidade. Todavia, e perante evidências dos potenciais perigos do exercício da liderança desprovido de valores, ética e moralidade, elevam-se as vozes em defesa de uma liderança virtuosa, capaz de aportar contributos significativamente positivos às organizações e seus colaboradores. Partindo desta premissa, esta investigação teve como objetivo analisar, com base nas perceções dos liderados, o impacto da liderança virtuosa no comprometimento organizacional, assim como o contributo deste último no desempenho individual. Sustentados numa metodologia quantitativa, inquirimos, numa primeira fase, 113 liderados provenientes de organizações localizadas no território português, com vista a apurar quais as virtudes que mais valorizavam num líder. Os dados para o teste de hipóteses foram recolhidos através da aplicação de uma bateria de testes junto de 351 liderados, também a exercer funções em organizações a operar em Portugal. Os resultados sugerem que as perceções dos liderados em torno de três dimensões de virtuosidade da liderança (liderança baseada em valores, perseverança e maturidade) contribuem para o comprometimento organizacional, sobretudo nas suas vertentes afetiva e normativa e, que este último, por sua vez, é capaz de influenciar positivamente o desempenho individual.

Internet Geography: New Spaces of Information

The objective of great investments in telecommunication networks is to approach economies and put an end to the asymmetries. The most isolated regions could be the beneficiaries of this new technological investments wave disseminating trough the territories. The new economic scenarios created by globalisation make high capacity backbones and coherent information society polity, two instruments that could change regions fate and launch them in to an economic development context. Technology could bring international projection to services or products and could be the differentiating element between a national and an international economic strategy. So, the networks and its fluxes are becoming two of the most important variables to the economies. Measuring and representing this new informational accessibility, mapping new communities, finding new patterns and localisation models, could be today’s challenge. In the physical and real space, location is defined by two or three geographical co-ordinates. In the network virtual space or in cyberspace, geography seems incapable to define location, because it doesn’t have a good model. Trying to solve the problem and based on geographical theories and concepts, new fields of study came to light. The Internet Geography, Cybergeography or Geography of Cyberspace are only three examples. In this paper and using Internet Geography and informational cartography, it was possible to observe and analyse the spacialisation of the Internet phenomenon trough the distribution of the IP addresses in the Portuguese territory. This work shows the great potential and applicability of this indicator to Internet dissemination and regional development studies. The Portuguese territory is seen in a completely new form: the IP address distribution of Country Code Top Level Domains (.pt) could show new regional hierarchies. The spatial concentration or dispersion of top level domains seems to be a good instrument to reflect the info-structural dynamic and economic development of a territory, especially at regional level.

Internet Geography: Spaces of Innovation

Information Society plays an important role in all kinds of human activity, inducing new forms of economic and social organization and creating knowledge. Over the last twenty years of the 20th century, large investments in telecommunication networks were made to approach economies and put an end to the asymmetries. The most isolated regions were the beneficiaries of this new technological investment’s wave disseminating trough the territories. The new economic scenarios created by globalisation make high capacity backbones and coherent information society polity, two instruments that could change regions fate and launch them in to an economic development context. Technology could bring international projection to services, products and could be the differentiating element between a national and an international economic strategy. So, the networks and its fluxes are becoming two of the most important variables to the economies. Measuring and representing this new informational accessibility, mapping new communities, finding new patterns and localisation models, could be today’s challenge. In the physical/real space, location is defined by two or three geographical co-ordinates. In the network/virtual space or in cyberspace, geography seems incapable to define location, because it doesn’t have a good model. Trying to solve the problem and based on geographical theories and concepts, new fields of study came to light. Internet Geography is one example. In this paper and using Internet Geography and informational cartography, it was possible to observe and analyse the spacialisation of the Internet phenomenon trough the distribution of the IP addresses in the Portuguese territory. This work shows the great potential and applicability of this indicator to regional development studies, and at the same time. The IP address distribution of Country Code Top Level Domains (.pt for Portugal) could show the same economic patterns, reflecting territorial inflexibility or, by opposition, new regional hierarchies. The spatial concentration or dispersion of top level domains seems to be a good instrument to analyse the info-structural dynamic and economic development of a territory, especially at regional level. At the same time it shows that information technologies are essential to innovation and competitive advantage.

Lá fora um lugar para existir/Abroad a place where to exist

A exposição “Artistas Portugueses - Lá Fora” pretende mostrar uma parte significativa da produção de artes plásticas que resultou de processos de migração que tiveram origem em território português. Integra uma multiplicidade de situações temporais e sociais que, para serem lidas, necessitam de alguma contextualização. Trata-se, tal como no caso da emigração económica, de uma emigração de sobrevivência, sendo que aqui o sentido do termo sobrevivência assume uma dimensão mais existencial. Para elas, partir quer dizer, ao mesmo tempo, resistir enquanto ser humano e existir enquanto criador. The exhibition “ABROAD” aims to show a significant part of the Fine Arts production resulting from migration procedures starting from the Portuguese territory. It comprises multiple periods of time and social situations which, in order to be comprehended, need to be contextualized. This is, just like in the case of economic emigration, an emigration for survival even if in this context the meaning of the Word survival assumes an existential dimension. For those people to leave means, simultaneously, to resist as a human being and to exist as a creator.

Historic and recent occurrences of pinnipeds in the Archipelago of the Azores

The Archipelago of the Azores (Portugal) is located between 378 and 418N and 258 and 318W and crosses the Mid-Atlantic Ridge. It is the most isolated archipelago in the Atlantic, situated 1600 km west of mainland Portugal and 3500 km from the eastern coast of the United States of America. At present, the only population of seals occurring in the Portuguese territory is found on Desertas Islands, Archipelago of Madeira, where a colony of 24 Mediterranean monk seals, Monachus monachus (Hermann, 1779), still persists (Pires and Neves 2001). Nonetheless, historical accounts reported by Frutuoso (1983) dating from the early to late 1500s mention sightings of ‘‘sea wolves’’ (the old Portuguese folk term for the Mediterranean monk seal) at several sites along the Azorean Island of Santa Maria. Little is known about the occurrence of monk seals in this area over the past five centuries, but the species certainly did not escape deliberate killing by the first settlers. While the early monk seal reports by Frutuoso (1983) are the only reports referring to the presence of colonies of seals in the Azores, more recently several sightings and strandings of vagrant seals of other species have been noted.

Improving the early diagnostic of prostate cancer by multiple biomarker detection with new biosensing devices

Prostate cancer (PCa) is the most common form of cancer in men, in Europe (World Health Organization data). The most recent statistics, in Portuguese territory, confirm this scenario, which states that about 50% of Portuguese men may suffer from prostate cancer and 15% of these will die from this condition. Its early detection is therefore fundamental. This is currently being done by Prostate Specific Antigen (PSA) screening in urine but false positive and negative results are quite often obtained and many patients are sent to unnecessary biopsy procedures. This early detection protocol may be improved, by the development of point-of-care cancer detection devices, not only to PSA but also to other biomarkers recently identified. Thus, the present work aims to screen several biomarkers in cultured human prostate cell lines, serum and urine samples, developing low cost sensors based on new synthetic biomaterials. Biomarkers considered in this study are the following: prostate specific antigen (PSA), annexin A3 (ANXA3), microseminoprotein-beta (MSMB) and sarcosine (SAR). The biomarker recognition may occurs by means of molecularly imprinted polymers (MIP), which are a kind of plastic antibodies, and enzymatic approaches. The growth of a rigid polymer, chemically stable, using the biomarker as a template allows the synthesis of the plastic antibody. MIPs show high sensitivity/selectivity and present much longer stability and much lower price than natural antibodies. This nanostructured material was prepared on a carbon solid. The interaction between the biomarker and the sensing-material produces electrical signals generating quantitative or semi-quantitative data. These devices allow inexpensive and portable detection in point-of-care testing.
