Municipal land allocations: a key for understanding tenure and social mix patterns in Stockholm

A socially mixed population is a political ambition in Stockholm. By providing a mix of tenure alternatives throughout all neighbourhoods this objective could, at least partially, be fulfilled. Since current tenure proportions display a weak balance in many neighbourhoods it could be assumed that governing politicians – by primarily utilizing Stockholm’s vast landownership and municipal housing developers – attempt to bridge observed gaps. Distribution of new rental and ownership apartments in municipal land allocations should acknowledge the existing tenure composition in a neighbourhood. Methodically this article focuses on all (nearly 50,000) apartments channelled through Stockholm’s land allocation system between 2002 and 2012. After classification of all apartments based on tenure, location, year and developer (private or municipal) the information is merged with yearly housing stock characteristics for 128 neighbourhoods. The outcome is a unique data set allowing for statistical assessment of whether Stockholm’s tenure (and in extension social) mix ambition is reflected in practice. The present article aims to highlight the crucial importance of landownership in Swedish municipalities with an aspiration to achieve or maintain a balanced tenure mix. While the findings indicate Stockholm is complying fairly well with its ambition, the results do reveal some contradicting signs.     

L'identification des zones calmes et un diagnostic d’équité environnementale à Montréal

Quiet urban areas are places with low noise levels that can help people to support physical and mental wellness. This paper has two objectives: to identify quiet urban areas in Montreal and to check for the presence of environmental inequities in access to such areas for vulnerable groups (children, older people, low‐income individuals, and visible minorities). Using a GIS‐based methodology, 2,282 quiet urban areas were identified in Montreal. The results of a mixed effects logistic regression model analysis showed that there are no major inequities in access to quiet urban areas for the population groups studied. The analysis did, however, revealed substantial spatial disparities in terms of the distribution of quiet urban areas across the boroughs and municipalities examined.     

Micro-imagerie de matériaux anciens complexes (I)

This article aims at presenting the first results of a transdisciplinary research programme in heritage sciences. Based on the growing use and on the potentialities of micro- and nano-characterization synchrotron-based methods to study ancient materials (archaeology, palaeontology, cultural heritage, past environments), this contribution will identify and test conceptual and methodological elements of convergence between physicochemical and historical sciences.     

Related variety and the dynamics of European photonic clusters

This article aims at assessing the role of related variety, that is, the relatedness of knowledge bases used by different sectors within a region, as a major driver of clusters’ development. Some recent theoretical papers underline the role of clusters as ‘knowledge platforms’ organizing the recombination of technologies in overlapping industries, following the seminal definition of clusters by Porter as ‘geographic concentrations of linked industries’. In order to investigate the role of related variety in cluster dynamics, we analyse the patterns of development of clusters specializing in photonics in Europe. Photonics constitutes a new and rapidly evolving set of technologies with a high expected degree of technological recombination. However, due to inadequate traditional sectoral classifications, we propose an original method to delineate the perimeter of photonics in patent databases. A two-step algorithm is then used to identify systematically photonic clusters in Western Europe at the local level. In the last part of the paper, a typology of technological trajectories of clusters over the last decades is developed and then correlated with a set of quantitative measures of technological relatedness. The results highly confirm the role of related variety as a major driver of success, particularly for the biggest European clusters.     

Travail, redistribution et construction des espaces économiques (XIe–XVe siècle)

Although a popular topic among historians for most of the XX^th century, the expansion of the European medieval economy has recently fallen out of favour. This paper seeks to bring attention back to this subject, at an important moment of the construction of a global European economy, by replacing it in a long term perspective, from the XI^th to the XV^th century, and by analysing its own process of economic development and growth trends. Particular attention is devoted to the social processes developed for the promotion of worker groups and productive activities, which made possible the intensification of labour that is remunerated by a complex set of mechanisms for the redistribution of wealth, which are among the most original creations of medieval societies.
