Sustainable management of metallurgical forest on Mont Lozère (France) during the Early Middle Ages

Mont Lozère, located in the French Massif Central region, provides an exceptional context in which to research the impact that charcoal production and metallurgy had on woodlands, along with the role that these activities played in changing the mountain landscape. This study provides an insight into the land use, forest management methods and metallurgical practices in the area during the Middle Ages (11th to 15th centuries). Medieval charcoal burning platforms, archaeological remains that have often been neglected in the past as a source of historical information, along with nearby smelting sites, were identified, sampled and analysed. In this paper, spatial analyses, radiocarbon dating and anthracological and dendro-anthracological studies have been combined in a unique manner. The results reveal that charcoal burners practiced beech coppicing, where the species and diameter of wood used remained the same over a period of four centuries. It is proposed that this form of metallurgical forest management be considered an early example of a sustainable utilisation of natural resources.     

Harmony and Melody in Discourse on European Cohesion

From a corpus constituted by the five Cohesion Reports written by the European Commission, the article, using the methods of textual analysis, highlights the production of a European discourse on the territories participating to a process of institutionalization. Thus, starting from various authors analyses who validate the idea of institutionalization, the authors propose here to further explore this idea, using a method based on a lexical analysis software. The aim is then, on the one hand, to assess the extent to which the discourse of the Commission has elements of stability to justify the idea of institutionalization or, in the other hand, the elements of change over time that could compromise the very idea of institutionalization. The authors present the following results: the Commission discourse has important features of stability. Nevertheless, beyond this finding, there are changes at work. Their expression is rendered possible by the polysemy of the notions mobilized, and they are driven partly by a “rational” representation, but above all by the interplay of the succession of tensions and mind-shaping contexts in the construction of Europe.     

SPATIAL MOBILITY AND RETURNS TO EDUCATION: SOME EVIDENCE FROM A SAMPLE OF FRENCH YOUTH*

ABSTRACT This study re‐evaluates the returns to geographic mobility and to the level of education taking into account the interaction between these two variables, and using the distance covered as a proxy for migration costs. We have at our disposal an original French database that permits precise calculation of the distance between the place of education and the location of first employment. For men, we find decreasing returns to spatial mobility as the distance covered rises and increasing returns to mobility with higher levels of education. The marginal returns to spatial mobility for women are lower across the board.     

Sharks in the lagoon? Fishing exploitation at the Neolithic site of Suwayh 1 (Ash Sharqiyah region,Arabian Sea,Sultanate of Oman)

The study of the fish bones from the Neolithic shell midden of Suwayh 1, excavated in the 2000s, identified a total of 1060 identifiable fish bones, from 23 families, 33 genera and 28 different species. Radiocarbon dating demonstrates that the sites date to the early 6th to mid 5th millennium BC. The results follow an eight-phase chronology highlighted by an earlier malacological study. The most important taxa were the Carcharhinidae (requiem shark), Rhinopteridae (cownose rays), Sparoidea (Sparidae and Lethrinidae: sea breams and emperors) and Ariidae (sea catfishes). The results of the fish study show that the Suwayh lagoon must have gradually opened up to the sea and been populated with mangroves. The unique presence of so many sharks at this site seems to indicate that the inhabitants had a special interest in shark fishing and that their location was ideal for this specialised activity. Two types of fishing nets and hooks have been discovered, which require the use of different fishing techniques.     

Bruit aérien et équité environnementale dans les quatre plus grandes métropoles canadiennes

Previous environmental equity studies have examined the spatial distribution of aircraft noise across cities. Their findings show that, in several cities, visible minorities and low-income populations are most affected by aircraft noise. In contrast, one study concludes that well-off populations are the most affected. These contradictory findings support the use of a comparative approach for several cities. The aim of this study is twofold. First, we want to identify if there are groups in the population that are in a situation of inequity to aircraft noise exposure in Toronto, Montréal, Vancouver, and Calgary. Then, we want to check if the exposure to the aircraft noise of the different groups varies significantly from one metropolis to another. We use the recommended noise exposure contour maps in Canada: the Noise Exposure Forecasts. Next, four variables are extracted from the 2016 Statistics Canada census at a fine-scale level (dissemination areas): that is, the percentages of low-income, visible minorities, 0- to 15-year-old, and 65-year-old and over populations. The results of a mixed effects logistic regression model show that environmental inequities in terms of exposure to aircraft noise for the four population groups are not consistent from city to city.
