Understanding palaeotopographical variability forms the basis for understanding prehistoric societies. Alluvial and lacustrine environments, in particular, are key areas with both a high archaeological and palaeoecological potential. However, the often deep stratification of these sites, the high water table and the complex sedimentological variations can hamper a detailed reconstruction of the spatial relationship between prehistoric settlement and their environment. Combining different remote and proximal sensing techniques and coring data, can offer detailed insight into such landscapes. More specifically, the integration of mobile geophysical methods allows the collection of unprecedented continuous information on large-scale palaeolandscape variability. In this study we present a combined approach in order to map and model prehistoric landscapes and river systems in and around a Late Glacial palaeolake in north-western Belgium. Based on filtered and unfiltered digital elevation models, a survey area of 60 ha was selected, in which detailed mobile multi-receiver electromagnetic induction survey was conducted. The results allowed for the delineation of palaeochannels in the area and enabled modelling the depth of these features in the survey area, providing insight into their flow characteristics. 14C sampling enabled the dating of the evolving river system to the transition between the Late Glacial and the Early Holocene. Through additional coring, this river system could be traced further through the palaeolake area. Based on these results a detailed reconstruction was made of the palaeotopography that harboured the Final Palaeolithic and Early Mesolithic occupation of the study site. 相似文献

A public latrine in the ‘Imperial Baths’ of Sagalassos was transformed into a dump site in the early Byzantine period. Several layers of urban waste, including ceramics, bones, glass and perhaps excrements were deposited on the floor. Faecal biomarker analyses and archaeobotanical analyses were conducted to reconstruct the history of the room. 5β-stanols of human origin, such as coprostanol, were found in the sewage channels together with mineralised plant remains, indicating a human faecal context. The botanical remains are furthermore representative of the Roman diet of the Sagalassians. Soil layers, deposited on top of the latrine floor and dating to the early Byzantine period, contained herbivore derived 5β-stanols, such as 5β-stigmastanol and epi-5β-stigmastanol. Additionally, a clear predominance of epi-5β-stanols over 5β-stanols showed that the animal dung has been subject to composting. In this period, the former latrine was clearly used as a manure production site which is further confirmed by stratigraphic evidence of large amounts of urban waste artefacts, which were commonly collected together with manure before application on the fields. The results of the present study support the theory that off-site potsherd scattering can be used as a proxy for manuring events. Additionally, the data show key evidence for vertical migration of 5β-stanols and presumably also for the leaching of bile acids. 相似文献

Despite being an everyday point of reference in Irish discourse, the extent to which the county serves as a locus of identification has been oddly overlooked in the Irish studies literature. In particular, the persistence of identification with the county of origin post-migration offers new insights on the construction and maintenance of identity within the Irish diaspora. Drawing on my PhD research on discourses of authenticity and identity among the Irish in England, this article investigates the ways in which county identity is invoked both by Irish migrants and those of Irish descent. It illustrates how the county is used as a rhetorical tool to situate the speaker within discourses of belonging and authenticity, but how this may also act as a constraint on the articulation of a collective, diasporic identity. It argues for a greater research focus on translocalism within the context of changing Ireland–diaspora relations. 相似文献

AbstractThis paper discusses the question of militant research from a perspective of critical knowledge production. In reference to our work on Dublin II and the European border regime, we discuss controversial issues, pitfalls and challenges we have encountered during out research and campaign activities. Among these are the strategic use of courts and a human rights language, differing modes of knowledge production between activism and academia and the issue of wage. The paper includes a discussion of the current place Asylum holds in the European border and migration regime from a historical and governmental perspective. 相似文献

We designed a geographical model for simulating the distribution of urban growth in systems of cities. The model incorporates the hierarchical and spatial diffusion of innovation cycles through gravitational interactions within a set of cities. Using theoretical simulations, we demonstrate that this model is able to reproduce the observed properties of urban systems for the log‐normal distribution of city sizes as well as the observed distribution of growth rates. Our experimentation was performed on a large harmonized historical database that includes a few hundred French urban agglomerations between 1831 and 1999 (Pumain‐INED database). Both spatial interaction and innovation cycles are necessary ingredients to explain the evolution of urban hierarchies. We suggest that Gibrat's generic stochastic growth model based on independent entities should be replaced by a more relevant model of spatially and temporally interdependent geographical entities. 相似文献

The francophone and anglophone minorities of Gatineau‐Ottawa appear to benefit from a privileged location. Living very close to their respective majorities, they simply have to cross the border in order to access resources to live in their own language and share their culture. However, a qualitative analysis of the discourse by Anglo‐Quebeckers and Franco‐Ontarians about their everyday life in the Nation's Capital Region shows that the border has more complex and often contradictory effects. In this article, we focus our attention on four particular manifestations of the border: (1) the border is transparent so that one can cross the Ottawa River without hindrance in certain contexts yet rather opaque in others; (2) one may transcend minority status through the strategic use of the border; (3) it creates a multi‐topic imaginary geography in which the border itself often becomes mobile; and (4) finally, the border can act as a mirror when the cross‐cultural intermixing it allows causes the Anglo‐Quebeckers and Franco‐Ontarians to question their identities, a questioning which would not be as intense in the absence of the border. The comparison of these two minorities makes it possible to highlight the asymmetrical nature of the effects of the border on their everyday life, identities, and sense of belonging. 相似文献
