A place in the sun? Discursive constructions of positive outcomes in post-migration stories in the Algarve

This study argues for more comparative research between seemingly different migrant groups, bringing a new focus on intra-European migration in Portugal by examining and comparing the reasons why migrants from different geographical origins choose to settle in the tourism-based Algarve region. Drawing on data collected from a questionnaire survey and interviews, the study first compares the profiles of two apparently distinct migrant groups – Northern and Eastern Europeans – and goes on to explore their discursive representations of migration experiences. Findings reveal that despite differences in initial motivations for moving to the Algarve, there are similarities between the two groups in terms of what leads them to settle in the region. Among both groups there is a high level of positive place-identity, suggesting that the specific context of the destination place plays a significant role in positive post-migration outcomes, something which is often overlooked in migration studies. Furthermore, the lived and perceived lifestyle affordances of the destination place, especially when discursively compared with the place and lifestyle left behind, are flagged by both groups and lend support to the idea that the role of lifestyle in migration has a wider significance than is usually credited.     

Pourquoi seules les villes sont-elles qualifiées d'intelligentes? Un vocabulaire du biais urbain

Since 2010, the term “smart city” has become a buzzword, used in a vague way to denote the increasing integration of information technology into city management processes and to describe the social and community processes they enable. The adjective “smart” is, however, only applied to cities: by implication non-cities (i.e., rural and peripheral regions) are not smart. In this paper we describe how the term “smart city” is used, and show that processes similar to those that make cities smart also occur outside cities. Reserving the term “smart” for cities therefore reflects a bias, similar to the bias that associates creativity and innovation with cities. As geographers we have become aware of our colonial and sexist biases: in this paper we argue that our urban bias is alive and well, and call attention to it.     

The role of arsenic in Chalcolithic copper artefacts – insights from Vila Nova de São Pedro (Portugal)

The Castro of Vila Nova de São Pedro (VNSP) is an emblematic settlement located at Azambuja, Portuguese Estremadura. It was occupied during the third and second millennia BC, predominantly during the Chalcolithic period. A diversified collection of 53 copper-based artefacts (most part in a fragmentary condition), belonging to an extensive metallic collection recovered during excavations carried out in VNSP, was studied using micro-EDXRF spectrometry, optical microscopy and SEM-EDS. Additionally, Vickers microhardness measurements were performed to establish the effectiveness of the thermomechanical treatment in the hardness of the artefacts. Results show that the Largo do Carmo, artefact collection is mainly composed of copper or arsenical copper, being 37% of the artefacts made of copper alloyed with arsenic (As > 2%). A statistically significant association was found between copper alloyed with arsenic and artefacts classified as tools/weapons (arrowheads, daggers and knives). In several cases, the presence of arsenic rich phases in the microstructure, resulting from an inverse segregation phenomenon, shows no evidence of chemical homogeneity control during the artefact manufacture. Microstructural analyses also show that the majority of this group (73%) was shaped with forging plus annealing operation cycles and 23% of the artefacts received a final cold hammering after the forging and annealing. An association between the presence of a final forging treatment and artefacts presenting higher arsenic contents was also identified. Nevertheless, no direct correlation was found between the arsenic content of the alloy and its hardness. Also no direct correlation was found between the hardness and a final forging operation. However, it was observed that a harder forging was applied to the cutting edge of the artefacts and consequently a high hardness in this area was obtained despite the arsenic content of the alloy. Concerning arsenical copper alloys, all evidences point out that the potential for obtaining a harder material was not recognized by the ancient metallurgists and the selection of the alloy was possibly made based on colour.     

Reaction to Fire of Existing Timber Elements Protected With Fire Retardant Treatments: Experimental Assessment

Fire safety is an important issue of building safety, especially when the building’s fire load contents enhance the risks of fire deflagration. When existing timber structures are involved, the most usual way to improve its reaction to fire is to treat wood with fire retardants. This study focuses on the surface protection of existing timber roof structures against fire, through the use of fire retardant (FR) treatments applied on site. An experimental investigation was carried out to study the effect of FR treatments on timber reaction to fire, with a special emphasis on timber members with biological deterioration and previously treated with preservative products. The behaviour and effectiveness of intumescent and non-intumescent treatments was also investigated. The study showed that the application of FR treatments improved the reaction to fire of timber, even in the presence of previous preservative treatments. However, the choice of the specific FR treatment should take into account the substrate conditions. In addition, test results suggest that protection systems involving multi layers (intumescent and non-intumescent) with different functioning modes each are likely to have a good global performance on the protection of timber elements against fire.     

Knowledge Transmission in Industrial Clusters: Evidence from EuroClusTex

Covering the knowledge economy scenario, this article attempts to illustrate the analysis of the employment of knowledge transmission channels in the EuroClusTex, cross-border textile and clothing cluster between northern Portugal and Galicia. Therefore, an exploratory research was conducted. Primary data were obtained through participation in events, from interviews with key informants (entrepreneurs, leaders of cluster support institutions and government representatives). The secondary data were provided by the cluster support institutions, international organizations and the literature review. The results showed that EuroClusTex contributes to the competitiveness of regions, boosting trade relations between Galicia and northern Portugal. The most effective knowledge transmission channels in EuroClusTex were identified as: imitation, relationship with suppliers, public policy and human resources training. Experiences similar to EuroClusTex can be considered and served as examples for the development of clustering policies in other countries.
