Portuguese publication in the aim of regional science: a study of articles published in RPER from 2003 to 2015

This paper is a study of the full content of articles published by RPER, the Portuguese Review of Regional Studies, from the time it was launched in 2003 until the first quarter of 2015. RPER is a journal edited by the Portuguese section of the European Regional Science Association, which was established in the first half of the 1980s. The Association (APDR) and the journal are the result of contributions by researchers and technicians from different scientific fields, including mainly Economics, Geography, Sociology, Engineering and Architecture. The main focus of these contributions is the socio-economic life of concrete sites, and the way this life is conditioned by resources and capabilities, the historical and cultural heritage and institutions. Content analysis was undertaken to identify the main subjects chosen during the total period under analysis, the nature of the articles published (theoretical or empirical) and the main analytical framework used. The analysis also covers sub-periods to investigate major trends found in terms of subjects chosen and analytical methods, questioning the rationale behind them. The paper concludes with a few notes regarding the social echo the research received and an identification of the main limitations of the research. In the first part of the article, we conduct a summary review of the genesis and evolution of Regional Science at international level to serve as a basis for the empirical approach developed.

As imigrantes brasileiras no jornalismo impresso regional

O estudo sobre a representação das brasileiras nos media é revisto sob vários aspectos e nos diversos meios de comunicação. Alguns estudos aprofundam a imagem das imigrantes, enquanto outros se concentram nos meios (rádio, televisão e imprensa). Existe ainda uma linha de investigação que se centra nos estudos da recepção. Todavia, verificámos a escassez de um estudo específico sobre a representação deste grupo no jornalismo de proximidade. Esta comunicação tem por objectivo apresentar parte dos resultados sobre a representação dos imigrantes brasileiros nas notícias publicadas durante o ano de 2007 em dois jornais regionais (um português – Diário do Minho – e um italiano – L'Adige). A escolha de um jornal externo ao contexto português foi extremamente enriquecedora para identificar possíveis convergências no tratamento dos imigrantes brasileiros (homens e mulheres) em diferentes contextos sócioculturais. Além disso, tanto Portugal como Itália foram países de forte emigração, influenciando os processos migratórios de ambos. A investigação inicial mostrou uma acentuada assimetria de género, o que nos levou a aprofundar a análise sob este aspecto. Observámos que os jornais analisados, em relação ao tratamento informativo da imigrante brasileira, trabalham na mesma linha dos jornais de âmbito nacional e, mesmo que em escala inferior, continuam a representar estas mulheres com um baixo estatuto, associadas a temas e comportamentos socialmente conotados com a marginalidade. De salientar que as imigrantes brasileiras que têm visibilidade nas peças noticiosas dos dois jornais são geralmente conotadas com a prostituição, clandestinidade, crime e exploração.

Highly functional and biodegradable nanofibrous scaffolds combined with stem cells for bone and cartilage tissue engineering

Among the various possible embodiements of Advanced Therapies and in particular of Tissue Engineering the use of temporary scaffolds to regenerate tissue defects is one of the key issues. The scaffolds should be specifically designed to create environments that promote tissue development and not merely to support the maintenance of communities of cells. To achieve that goal, highly functional scaffolds may combine specific morphologies and surface chemistry with the local release of bioactive agents. Many biomaterials have been proposed to produce scaffolds aiming the regeneration of a wealth of human tissues. We have a particular interest in developing systems based in nanofibrous biodegradable polymers1,2. Those demanding applications require a combination of mechanical properties, processability, cell-friendly surfaces and tunable biodegradability that need to be tailored for the specific application envisioned. Those biomaterials are usually processed by different routes into devices with wide range of morphologies such as biodegradable fibers and meshes, films or particles and adaptable to different biomedical applications. In our approach, we combine the temporary scaffolds populated with therapeutically relevant communities of cells to generate a hybrid implant. For that we have explored different sources of adult and also embryonic stem cells. We are exploring the use of adult MSCs3, namely obtained from the bone marrow for the development autologous-based therapies. We also develop strategies based in extra-embryonic tissues, such as amniotic fluid (AF) and the perivascular region of the umbilical cord4 (Whartonâ s Jelly, WJ). Those tissues offer many advantages over both embryonic and other adult stem cell sourcess. These tissues are frequently discarded at parturition and its extracorporeal nature facilitates tissue donation by the patients. The comparatively large volume of tissue and ease of physical manipulation facilitates the isolation of larger numbers of stem cells. The fetal stem cells appear to have more pronounced immunomodulatory properties than adult MSCs. This allogeneic escape mechanism may be of therapeutic value, because the transplantation of readily available allogeneic human MSCs would be preferable as opposed to the required expansion stage (involving both time and logistic effort) of autologous cells. Topics to be covered: This talk will review our latest developments of nanostructured-based biomaterials and scaffolds in combination with stem cells for bone and cartilage tissue engineering.

Índice Digital Regional 2014

O objetivo subjacente a toda a investigação que deu origem ao Índice Digital Regional (IDR), inserida num projeto de doutoramento, ia no sentido da “compreensão da realidade da Sociedade da Informação nas sete regiões NUTs II portuguesas, comparando-as e contrastando-as”. À semelhança do que acontece em grande parte dos indicadores de desenvolvimento, em que as assimetrias regionais são uma evidência verificada há várias décadas, importava perceber até que ponto o desenvolvimento da Sociedade da Informação em Portugal está a ser desencadeado sem ter ou não em atenção os valores da equidade, da coesão nacional e da solidariedade regional. Este artigo analisa os resultados do IDR recalculado com os dados estatísticos mais recentes.
