Cross‐border residential mobility (CBRM) has so far largely been approached from a transnational perspective. However, recent developments in border studies and transnationalism give rise to certain doubts. While border studies have come to include mental borders next to physical borderlands, transnationalism today refers not just to cross‐border movements but also to identities trans‐cending the national. But border studies have shown that the increased crossing of borders is not necessarily coupled with their diminished significance. CBRM is a particularly interesting phenomenon as it entails the continuous crossing of a physical border, but the question is whether it also implies the erosion of mental borders and the emergence of transnational ties. While drawing on experiences from parallel cases, my study focuses on Poles from Szczecin moving just across the boundary to Vorpommern, Germany. Some are integrating there, but their large majority appears to carry on with everyday life in Poland as before moving. This settlement has triggered considerable resentment among local Germans, who as a reaction mark the borderland discursively and physically. As my survey shows, while both groups regularly cross the physical border, many even among the cross‐border residents consider it as a necessary dividing line or prefer cooperation to be reserved to some activities. Hence, unlike longdistance migration leading either to diaspora identities or to gradual dissolution in the majority culture, CBRM appears as a specific form of international migration where the physical proximity allows such intensive links with the country of origin that transnational effects are mitigated.  相似文献

This paper documents court‐imposed bail and sentencing conditions with spatial dimensions, such as red zones, no contact conditions, curfews and prohibitions to demonstrate, issued in the context of criminal proceedings. These conditional orders, which are growing in importance and have a significant impact on the lives of marginalized groups of people, have not received the attention they deserve in the literature. As opposed to better publicized forms of spatial regulation such as legislation or policing strategies, these conditional orders are a distinctive form of spatial tactic that rely on ancient and routinized rules of criminal procedure and the practices of the courts. In order to understand this spatial tactic, and its impact on marginalized people's rights and uses of spaces, we argue that it is necessary to pay attention to the legal rationalities, knowledge and practices that sustain them.  相似文献

Beginning with the first travelogues of the late 1890s, the film and tourism industries collaborated both directly and indirectly to shape representations of North America’s western landscape and its people. These non-narrative motion pictures intersected with the rise of mass consumerism, modern tourism, the forces of imperialism and colonialism, as well as industrialized forms of transportation. In particular, railroad travel films from the Canadian Pacific Railway Company and the Northern Pacific Railway Company transformed motion-picture goers into armchair tourists, exposing audiences to the scenic wonders of the West. These transcontinental railroads, themselves products of nation-building initiatives, competed against one another to increase passenger traffic by marketing the sublime and often overlapping landscapes of the American and Canadian Wests as potent nationalist and unifying symbols that heralded each country’s uniqueness.  相似文献

Several traces of biological interaction were found on penguin bones from the basal levels (Aquitanian) of the Miocene Gaiman Formation in the lower Chubut valley of the Provincia del Chubut, Argentina. The fossil-bearing beds were deposited in littoral to sublittoral environments within sediments of mostly pyroclastic origin. We interpret many traces to have been produced by predators and/or scavengers while the penguins were still in a breeding area. Many bones show cracking marks due to aerial exposure. The material is disarticulated as is usual in recent breeding areas. Potential predators were coeval terrestrial mammals, most probably marsupial carnivores. After a marine transgression, these bones were buried or exposed on the sea bottom where they could be colonized by algae, sponges, cnidarians, and other benthic organisms. We identified sponge borings in several bones. Other traces are interpreted to have been produced by echinoderms feeding on sponges or algae. No evidence of other invertebrate predators such as muricid or naticid gastropods, or decapods was found. Finally, other traces appear to have been generated by shark and possibly teleostean vertebrates feeding on epibionts. One coracoid is interpreted to have been marked by a shark that is common in the Gaiman Formation, the carcharhiniform Galeocerdo aduncus. From an ethological (Seilacherian) classification, traces on bones from the Gaiman Formation include Domichnia (sponge perforations), Praedichnia (terrestrial marsupials, sharks, teleosteans) and Pasichnia (echinoderms). Remarkably, remains of marine organisms with skeletons made of calcium carbonate are very poorly preserved in the Gaiman Formation. Only large oysters, sparse shell fragments, skeletal moulds, and bioturbation is evident. The fossil assemblage is mainly composed of phosphatic (e.g. teeth, bones, crustacean parts) and siliceous (sponge spicules, diatoms) remains.  相似文献
