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.     

New Methods on Old Castles: Generating New Ways of Seeing

THE USE of new methods on old castles generates new ways of seeing and leads to new interpretations. Three types of analyses are demonstrated on four late 13th-century castles from North Wales. Feature Analysis invokes the use of a decision-tree to help in the determination of room function. Access Analysis via access diagrams is used to understand the functional organization of rooms within each castle. Finally, a Comparative Analysis employing access diagrams, plans, a table and a cumulative graph is performed to note developmental trends in the castle designs, to detect differences between the castles, and to lead to new interpretations or new working hypotheses.     

A rallying point for different predators: the avian record from a Late Pleistocene sequence of Grotte des Barasses II (Balazuc,Ardèche,France)

The presence of processed birds in the archeological faunal record is considered key to assessing human dietary evolution. Taphonomic studies on birds from sites older than Marine Isotope Stage (MIS) 2 have become relevant in the last few years, leading to the proposal of more complex scenarios of human subsistence. Several works have demonstrated direct evidence of bird consumption by Homo prior to anatomically modern humans in Europe; however, others support the hypothesis of non-anthropogenic bird accumulations. This has led to the necessity of determining what elements or factors cause the human exploitation of birds in some archeological sites before the end of the Pleistocene. The Grotte des Barasses II site is located within this framework. Short-term human occupations have been attested by the presence of lithic tools and processed macrofaunal remains. Additionally, a small assemblage of bird bones has also been recovered. Here, we present a detailed taphonomic study with the aim of exploring possible relationships between these avian taxa and human occupations. Despite the fact that Neanderthals inhabited the cave, avian specimens show damage pointing to different causative agents. Direct evidence (digestion, gnawing) indicates that mammalian carnivores and nocturnal raptors were mainly involved in the accumulation of bird bones. We propose some factors that might determine whether or not small game was exploited in this specific locality and emphasize the importance of such analytical approaches in the general interpretations of the Pleistocene sites.     

Hard core and cutting edge: experimental manufacture and use of Magdalenian composite projectile tips

The technology of the European Upper Palaeolithic yielded abundant evidence of the use of composite projectile heads, in the form of osseous points on the side of which one or several (micro)lithic elements are attached. Yet, little experimental work has been devoted to testing and assessing the parameters of use of this type of composite tips. In this paper we present a pilot experiment with replicas of Magdalenian composite spear tips, made of an antler point with one or two rows of flint backed bladelets. Two series of replicas were manufactured after the lithic and osseous record of, respectively, the Lower Magdalenian from southwest France (c. 20–18 Ky cal BP) and the Upper Magdalenian of Pincevent in the Paris Basin (c. 15–14 Ky cal BP). The 34 experimental composite heads were hafted to spears that were then shot with a spearthrower at the carcasses of two young deer. The results provide some insight into the performance characteristics of the osseous and lithic components, both in efficiency and durability. Finally, possible improvements of the experimental protocol are discussed, as well as the implications of our results for the understanding of projectile point variability in the Upper Palaeolithic.     

The European Alps – an exceptional range of mountains? Braudel’s argument put to the test

In his classic work about the Mediterranean in the period of Philipp II, French historian Fernand Braudel designates the European Alps an ‘exceptional range of mountains’ and offers several reasons therefor. In contrast to other parts of Braudel’s work, this argument has gone largely unnoticed in scholarship. This article intends to put it to the test in light of recent publications on the Alps. The first two sections give an outline of Braudel’s dealings with mountain regions and of historical research on the Alps from the 1970s onwards. The third section comments on the suitability of Braudel’s criteria for empirical assessments in a comparative perspective. In the conclusions it is argued that Braudel’s general intuition is still valid to some degree. It is less certain, however, that all the criteria are pertinent. More importantly, the findings emphasize the fact that the history of the Alps cannot be studied without paying close attention to their links with the surrounding lowlands. Thus the question of alpine exceptionality raises the question of the special trajectory of these lowland regions within the larger history of Europe.
