"This paper presents a two-sector dynamic model of regional population change. The model contains a migration equation, an earnings equation, and an amenity equation for each region. In the context of this model, migration is seen as a disequilibrium process through which the regional populations move towards equilibrium positions. Migration occurs when one region is perceived to be superior to the other on the basis of its earnings and amenity levels. Equilibrium is achieved when population movements between the regions eliminate any differences in their relative attractiveness. A comparative-static analysis of the model is presented to analyze the effects of policy changes and exogenous shocks on the distribution of population among the regions." The geographical focus is on the United States.  相似文献

The article addresses narratives that tell of a member of the 10 Lost Tribes of Israel who comes to the rescue of a Jewish community. The tales were documented at the Israel Folktale Archives, in the second half of the twentieth century, and were told by informants from Morocco and Greece. While it is probably impossible to trace the exact routes of these “cultural possessions”, around and across the Mediterranean, the texts nevertheless provide a glimpse into the ways in which a network of Jewish communities shared a meta-narrative while adapting it to their own regional contexts. Although these tales are quintessentially diasporic, they also provided a platform for negotiating post-exilic identities in the new Israeli national context.  相似文献

The metallurgical analysis of a copper bead from a Neolithic burial (6th millennium ) at Mehrgarh, Pakistan, allowed the recovery of several threads, preserved by mineralization. They were characterized according to new procedure, combining the use of a reflected-light microscope and a scanning electron microscope, and identified as cotton (Gossypium sp.). The Mehrgarh fibres constitute the earliest known example of cotton in the Old World and put the date of the first use of this textile plant back by more than a millennium. Even though it is not possible to ascertain that the fibres came from an already domesticated species, the evidence suggests an early origin, possibly in the Kachi Plain, of one of the Old World cottons.Résumé: L'analyse métallurgique d'une perle en cuivre, provenant d'une tombe néolithique (VIe millénaire av. notre ère) de Mehrgarh, Pakistan, a permis la découverte de plusieurs fibres textiles, conservées par minéralisation. Elles ont été caractérisées par une nouvelle méthode, combinant l'utilisation d'un microscope à lumière réfléchie à celle d'un microscope électronique à balayage, et ont été identifiées comme étant du coton (Gossypium sp.). Les fibres de Mehrgarh constituent la plus ancienne attestation du coton dans l'Ancien monde et son utilisation a pu être reculée de plus d'un millénaire. Bien qu'il ne soit pas possible d'attribuer avec certitude les fibres à une espèce déjà domestiquée, ces nouvelles données suggèrent une origine ancienne, éventuellement dans la Plaine de Kachi, d'une des espèces cotonnières de l'Ancien monde.  相似文献

Over the last decade, numerous crime prevention programmes have been implemented across the German school sector. Although several serious violent attacks have happened in the last 12 years in German schools, the emergence of crime prevention programmes within the education sector cannot simply be conceived as a reaction to a rise in youth crime. Following Michel Foucault's writings on power and governmentality, and drawing upon extracts of a discourse analysis of crime prevention programmes and political speeches, we argue that crime prevention within German schools signifies a new mode of governing childhood. Although we focus on Germany, our findings may illustrate an international trend within education policy, which first tends to spatialise socio-structural problems and transform them into local solutions, and second seeks to create childhood subjectivities that cause children to feel responsible for their own safety, while simultaneously subjecting children and young people to wide-ranging social control via area-based networks.  相似文献
