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.     

Assessing XRF for the geochemical characterization of radiolarian chert artifacts from northeastern North America

The purpose of this paper is to emphasize the benefits of adopting non-destructive energy dispersive X-ray fluorescence (ED-XRF) as a first-order technique to determine chert whole-rock geochemistry for archaeological sourcing. Chemical signatures for the Touladi and La Martre prehistoric quarries from the lower St. Lawrence and Gaspé Peninsula region of Quebec, Canada, are determined and serve as references to test the provenance of regional chert artifacts. Chert experimental flakes, created from quarry geological hand samples, are analyzed and used to validate the method. Archaeological flakes and tools recovered from three archaeological sites are analyzed and tested against quarry samples. Geochemical diagrams and Principal Component Analysis are used to establish artifact-quarry relationships. The effects of surface weathering on the geochemical analysis of archaeological chert artifacts are presented. Sample restoration and research avenues are discussed and proposed to further enhance the robustness of future chert geochemical data sets.     

Act Up ou la tentation du politique: Sur les recompositions de la gauche protestataire de 1997 à 2002

L'article est une contribution à la compréhension des relations entre l'espace des mouvements sociaux et le champ politique au travers de l'étude d'un des mouvements les plus actifs de ces dernières années, Act Up. Cette association a entrepris à deux reprises de transgresser les frontières qui séparent militantisme contestataire et action politique partisane: la première fois en lançant à la veille des élections législatives de 1997 un appel intitulé ‘Nous sommes la gauche’, la seconde en formant le projet de présenter ses propres candidats aux élections législatives de 2002. L'étude de ces deux initiatives permet d'approfondir la connaissance des recompositions qu'a connues la gauche française au cours d'une période marquante de son histoire récente, celle du passage au pouvoir de la ‘gauche plurielle’.     

Milieux innovateurs: Determinants and policy implications

National and regional differences are more and more frequently explained by differences in milieux. This type of explanation raises three questions: Can we identify milieux? What are the determinants of milieux? Are there differences between industries in the matter of determinants of milieux? Most studies on milieux innovateurs are based on case studies and qualitative data. This paper is quantitative and comparative in nature. It attempts to identify milieux and their determinants by using data from the 1999 Statistics Canada Innovation Survey. Based on two synthetic indicators of interactions (weak/strong) and learning (weak/strong), four categories of milieux innovateurs are differentiated which become the dependent variables. In order to see what the determinants of the various milieux innovateurs are and to see in what ways the most favorable milieux innovateurs compare to the others, binomial logit models have been estimated for four industries using the following independent variables: competitive pressures, barriers to knowledge exchange, use of government support, number of employees, collaborative arrangements, R&D activities, regions.     

Stable isotopic composition of chitin from arthropods recovered in archaeological contexts as palaeoenvironmental indicators

The effects of biodegradation and heating on the stable carbon, nitrogen, hydrogen and oxygen isotope ratios of chitin in arthropods were studied. Chitinous exoskeletons from seven aquatic arthropod species were subjected to anaerobic marine biodegradation in mud, to terrestrial biodegradation in soils, and to thermal degradation under anaerobic and aerobic conditions. The isotope ratios of chromatographically separated D-glucosamine hydrochloride and derivatives from treated and untreated specimens were then compared. Carbon, nitrogen, oxygen and hydrogen stable isotope ratios were all found to be conserved during partial degradation of chitin. Micromorphological comparative studies using scanning electron microscopy (SEM) and transmission electron microscopy (TEM) indicated that no fungal chitin or other contaminants were present in the chitins that were chemically isolated from biodegraded substrates. Our results indicate that it will be possible to use stable isotope ratios of archaeological chitin samples for environmental and climatic reconstructions. An illustration of the utility of this approach comes from the observation that the stable isotope ratios of chitin from crustacean exoskeletons recovered from archaeological sites with ages up to 1400 years bp are in good agreement with measurements on modern crustaceans from similar environments.
