Archaeological practice within the European context of heritage management is facing huge challenges in ways of recording and reproduction of ex-situ preserved sites. As a consequence of the Valletta-treaty, numbers of archived images and drawings of excavated structures as prime sources of past human activity, are exponentially growing. Contrarily to portable remains however, their future study and revision is biased by the two-dimensional character of the recorded data, rendering difficult their future reconstruction for new study or public dissemination. A more realistic three-dimensional (3D) way of recording and archiving should be pursued. In this paper the possibilities for 3D registration of archaeological features are examined in a computer vision-based approach using the PhotoScan software package (Agisoft LCC). It proved to be a scientific and cost-effective improvement compared to traditional documentation methods. Advantages can be found in the high accuracy and straightforwardness of the methodology. The extraction of an orthophoto or a Digital Terrain Model from the 3D model makes it feasible to integrate detailed and accurate information into the digital archaeological excavation plan. The visual character of 3D surface modeling offers enhanced output-possibilities allowing a better documentation of in-situ structures for future research and a higher public participation and awareness for the archaeological heritage. 相似文献

Wild(er)ness: Reconfiguring the Geographies of Wildlife 总被引:1,自引:0,他引:1
Sarah Whatmore Lorraine Thorne 《Transactions (Institute of British Geographers : 1965)》1998,23(4):435-454
Amidst millennial talk of the 'end of nature' ( McKibben 1989 ), this paper examines the precarious geographies of 'wildlife' in rather less apocalyptic terms. Animal (and plant) species designated wild are placed categorically outside the ambit of 'human society', confined to inhabiting the margins and interstices of the social world. Yet, we contend, such animals have long been routinely imagined and organized within multiple circuits of social power, which (re)configure them in important ways. These social orderings of animal life confound the moral geographies of wilderness, which presuppose an easy coincidence between the species and spaces of a pristine nature. In this paper, we employ the fluid spatial vocabulary of topology to map a more volatile and relational conception of the fabrics of wildlife. Our arguments are worked through glimpses of two historically very different social orderings of 'wild' animals – those associated with the military vernacular of the gladiatorial games of Imperial Rome, and the scientific vernacular of endangered species listing and conservation under CITES (the Convention on the International Trade in Endangered Species). These 'foldings' of wildlife in distant time/space aim to disrupt the linear historical narratives of 'civilization' and 'evolution', which consign wildlife to marginal spaces with a teleological destiny of erasure. 相似文献

This article focuses on a community located in downtown Rio de Janeiro that was destroyed to make way for the commemorations of Brazil’s Centenary of Independence in 1922. Morro do Castelo was once a space customarily inhabited by Afro-descendants, but Italian and Portuguese immigrants predominated there by the time of its destruction. I argue that whatever Castelo’s racial heterogeneity it was imagined and treated as a black space by planners and policy makers, hence its disposability. In Castelo's neglect during the colonial period and in the urbanization projects that sought to destroy it in the first two decades of the 20th century, one can discern the continuity of imperial processes of ruination of racialized spaces and bodies. The article examines ways in which residents of Morro do Castelo established territory and engaged in various forms of refusal when faced with the ruination of their neighborhood. The spatial practices of the hillside’s diverse population suggest that its various racialized and ethnic groups mapped difference onto a palimpsestic site that defied official classificatory systems and troubled official mappings of the concept city. 相似文献

In this article it is argued that conventional agro-ecological and organizational concepts used in pastoral development are strongly biased towards the formulation and enforcement of norms. This leads development experts to attempts to control pastoralists and their herds. The policies and development interventions based on these assumptions have been largely unsuccessful. As a consequence attention for dryland areas and pastoral development has declined among researchers and development agencies. An important reason for this failure is the fundamental misfit between these normative concepts and the reality of dryland ecosystems and pastoral society. In order to show this, an alternative view on rangeland ecology and pastoral society is presented, supported by a case study of Fulbe pastoral society in dryland Central Mali. The authors argue that approaches to pastoral development must be revised in the direction of the dynamics inherent in the pastoral way of life. 相似文献

Testing for the Law of One Price and Identifying Price-Leading Markets: An Application to Corn Markets in Benin 总被引:1,自引:0,他引:1
A data-determined method is proposed to test for the law of one price as a long-run equilibrium condition and to identify which markets in a network of spatially dispersed commodity markets quote the reference price. The method consists of supplementing Johansen's FIML cointegration procedure with a permanent-transitory decomposition and rules of inference in linear time-series models with unit roots. As an example, we apply our method to prices of six corn markets in Benin. We find that the law of one price holds in the long-run. It appears that two rural markets quote the reference price: their prices adjust fastest towards the permanent change induced by the common stochastic trend. 相似文献

Although the aetiology of bone pathologies in cattle is poorly documented, various deformations in the skeleton have been attributed to draught exploitation in the archaeozoological literature. This paper summarizes the results of an osteological study that was undertaken on the feet of modern draught oxen. This led to the definition of a series of draught‐related anomalies. In an attempt to describe the pathologies in a more consistent and quantitative way, a scoring scale for each individual bone pathology was established. The developed method is applied to cattle remains from four Roman and one late medieval site. The distribution of the observed pathological indices (PIs) on the first phalanges is interpreted in terms of the age structure of the cattle populations, and the possible modes of cattle exploitation and meat consumption in various settlement types.
