La mobilité forcée des personnes utilisatrices de drogue par injection et inhalation en situation d'itinérance à Montréal

This article focuses on the various actors in the urban setting who contribute to the increase in the forced mobility of homeless injection drug users and crack smokers in Montréal, Canada. The objective is to analyze who these actors are and how they contribute to increasing this forced mobility from the perspective of homeless injection drug users and crack smokers in relation to three needs : basic needs, acquisition of financial resources, and drug use. One hundred and six semi-structured interviews were conducted among this population. The results indicate that various actors—police officers, community organization, peers, municipal administration, storekeepers, and residents—contribute to the forced mobility of this population in their daily activities. As for their needs, it is when they use drugs, sleep, or loiter that they are more likely to experience events of forced mobility. Police officers are by far the actors who contribute the most to this, often in a repressive way. The role of the municipality is also a determining factor in the daily activities of homeless injection drug users and crack smokers.     

Renegotiating the Reproductive Bargain: Gender Analysis of Economic Transition in Cuba in the 1990s

This article argues that Cuba's economic demise following the collapse of the former Soviet Union should be seen as a crisis in reproduction as well as a crisis in consumption and production. Using qualitative field research carried out in 1994 and 1995 in Havana and in the province of Matanzas, the author shows that the commodities and services required for reproduction could no longer be guaranteed through the distribution system of the Cuban state. Consequently, people began to devise a range of survival strategies in order to ensure the reproduction of their households, including trading in unofficial markets, leaving formal employment and engaging in a portfolio of income-generating activities in the informal sector. Such strategies were patterned by the existing sexual division of labour and show a reinforcement of traditional gender roles. The article argues that these changes will have important political as well as economic consequences for Cuba's future.     

The Political Economy of Electrical Power Generation

This article examines the procurement practices of Canada s three largest electric power utilities, Ontario Hydro, Hydro Quebec, and B.C. Hydro in terms of their impact on the technological development of the electrical power equipment industry in Canada. The theoretical underpinnings of this analysis are that under certain economic, technical and institutional conditions, procurement as managed by large publicly owned corporations with a high level of technical capacity can be a powerful instrument of industrial innovation. The paper describes how in the face of weakening market power following the twenty-year expansion phase in the industry (1960–80) and global restructuring among electrical power equipment suppliers, the three utilities have been forced to reassess conflicting commercial and technological objectives. The authors point to Hydro Quebec's signing of a recent series of strategic production agreements with key suppliers as an example of a new approach lo procurement through concentrated use of limited market power in critical product areas. The paper concludes that the distribution of risks involved in technology development between buyers and sellers is dependent on market structures. Secondly, the nature of these client-supplier interactions in management of risk will reflect the internal coherence of an organization's commercial and technological strategies.     

Paleodemographic analysis of a fossil porcupine (Hystrix refossa Gervais, 1852) population from the Upper Pleistocene site of Geula Cave (Mount Carmel,Israel)

For decades zooarchaeological studies mainly focused on teeth age profiles to derive central hypotheses concerning human subsistence during the Pleistocene. Behavior was often related to hunting and/or scavenging strategies according to two models: attritional versus catastrophic. However, few studies have estimated basic demographic parameters using standard methods of population ecology, which are necessary for a more confident interpretation of animal paleopopulation structures. Thanks to a remarkably rich fossil bone assemblage from the Upper Pleistocene cave of Geula (Mount Carmel, Israel), in this paper we perform a paleodemographic analysis of Hystrix refossa, Gervais 1852 (Mammalia, Rodentia). We first consider phylogenetic and morphometric dental criteria for the comparison of Pleistocene porcupine species, followed by an examination of taphonomic conditions of the bone assemblage. We focus strongly on the age structure of the fossil population, presenting a new methodological approach that combines life tables and Leslie matrix models – one of the best-known methods in population ecology for assessing population growth and age distribution. We detail demographic parameters derived from cross-sectional life tables and past trends in the porcupine population at Geula Cave using simple matrix projection model. Finally, we were able to perform an elasticity analysis to identify which demographic component was potentially the most critical for influencing growth. We show that the population of H. refossa did not decline or shrink but was stable. Our results permit us to characterize Geula Cave as a natural shelter for porcupines, with limited evidence to scavenging and hunting by either hyenas or humans.
