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

Traditionally, Iranian studies recognize in the oldest‐known Iranian, and Mazdean, text the work of Zarathustra. At the same time, scholars seek, in these difficult and sometimes incomprehensible verses, the doctrine that the Mazdean religious tradition of the Sassanian period attributes to its legendary founder: the passage to monotheism and an eschatology founded on a dualist conception of the world. However, a strict study of the language of the Gâthâ, in the perspective opened up by Helmut Humbach, is not favorable to such an interpretation. The eschatological vocabulary proves illusory and, to a great extent the same is true of the eschatology. As for the Gâthic religious system, it is neither truly monotheistic nor truly polytheistic. To grasp its nature, it is necessary to describe all the nuances and to situate it in an historical perspective.  相似文献

During the 1984–1985 British miners' strike and in its immediate aftermath, women activists produced a series of publications involving creative writing, which sought to communicate the strike from their own perspective. The production and sale of publications were a practical activity in support of the strike and in defence of community. We argue that insofar as writing was also a means whereby the women who worked to make sense of themselves in an emergent situation for which there was no precedent, an analysis of such writing offers opportunities for a broader understanding of the strike. Writing enabled the women to affirm their class-based political loyalties while expressing the complexities and contradictions of gender relationships and roles. Writing as a reflexive act contributed to a clarification of those aspects of female lives which they valued, facilitated an expression of their emotional response to their experience of activism and enabled them to articulate a moral-political position within which they worked with ambiguity and contradiction. This article suggests that cultural texts of this type in themselves can only be properly understood in the context of structural and historical relations of power and that the context and conditions of production of writing are particularly pertinent to this process.  相似文献

Mountain regions represent a substantial part of Soviet territory, a total of 652 million hectares, which is 29.5 percent of the total area, or 21 percent of the usable agricultural area (including livestock range), but only 3.8 percent of the arable land. Soviet policy toward mountain development has varied over time. At first, mountain areas were considered a symbol of backwardness, and were not allocated a role in the Soviet modernization program. In recent decades, attitudes have been changing, but solutions have differed. The author, focusing on the eastern portion of the Greater Caucasus, shows on the basis of the literature and personal observations how the policy in Dagestan and in Azerbaijan, by allocating lowland activities to mountain populations, differs from Georgian policy, which since 1976 has actively sought to foster a revival of mountain economies.  相似文献

This paper provides a new, interpretive gazetteer and chronology of Hadramawt’s highland monuments based on results from archaeological survey and test excavations by the RASA‐AHSD (Roots of Agriculture in southern Arabia‐Arabian Human Social Dynamics) Project. With the exception of a few incidental sightings and an unpublished pipeline survey, the prehistoric record of southern Yemen’s highland plateau has been largely unknown. There are few settlements, so that understanding human landscape history must begin with the numerous small‐scale stone monuments left by mobile people. With examples representing monuments from the fifth, fourth, third and first millennia BC, the corpus of small excavations and radiocarbon dates reported here provides the first guide to the monument types of South Arabian highlands. Monument building began under more moist conditions and appears to have commemorated animal sacrifices long before commemorating mortuary rites and interment. There appears to be a temporal break of 1000 years before the widespread and varied practices of Bronze Age tomb construction, which lasted through the third millennium BC. After another break in monument construction, tombs were reused in the first millennium BC, sometimes with successive ritual visits. The data presented offer new material for the interpretation of the lives and activities of prehistoric pastoralists throughout the Holocene.  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
