First visited by westerners in the mid-nineteenth century, Saharan rock art has since received a great deal of attention. The richness and diversity of this region is recognised by the inclusion on the UNESCO World Heritage list of three properties: Tassili-n-Ajjer in Algeria, Tadrart Acacus in Libya, and Ennedi in Chad. The situation in many North African countries now makes this vast region very difficult to access: safety in the field is not guaranteed and few research funds are available. Today, a new generation of African and foreign scientists has no access to rock art sites in the north of the continent and the lack of fieldwork may entail a lack of safeguard and awareness. The growth of digital technologies over the last 15 years has revolutionised methods for recording rock art sites. Digital technologies are also used to mitigate the gap between artworks and accessibility in those countries where turmoil and social instability make fieldwork impossible. However, much of the documentation and most digital recordings of artworks currently available on the Internet lack an archaeological context. Equally, many of these websites barely mention methodological and theoretical aspects. It is also difficult to understand the extent of awareness among local communities in remote areas—sometimes suffering a digital and linguistic divide—and if (and how) they are genuinely able to exploit these digital resources. Here, I collate some examples from different parts of the Sahara illustrating that the recording, management and dissemination of rock art still present highs and lows. I argue that we should share theories and methods within the digital scientific community, with a view to adopting a shared nomenclature and a public thesaurus, making our cataloguing criteria explicit and, finally, developing an ethical code of conduct involving local communities. 相似文献

This article discusses the financial policies of the Papal States from the late eighteenth to the mid-nineteenth century in relation to the rest of Europe, and especially Italy. Its crucial starting point is the Napoleonic economic reforms, which had important and often lasting effects throughout its former empire. French reliance on debt reduction and heavy though equitable taxation improved the financial conditions of most European lands even as they convulsed from the protracted wars. The economic austerity prior to 1814 forced post-Napoleonic Europe to make decisions on the degree of continuity on these two financial fronts. Political instability beginning in the 1820s for some, and the early 1830s and late 1840s for the rest, upset the rather tenuous financial position that most lands found themselves in. For the Papal States, the Napoleonic period improved its financial position to the detriment of ecclesiastical institutions. The period also revealed the inherent flaws in its financial system, necessitating a decentralized approach to the restoration, relying on individual (or institutional) initiatives and large foreign loans, in lieu of overarching policies. By the 1850s, a further lack of financial control induced the renewal of Peter’s Pence. 相似文献

Advanced data capture techniques, cost-effective data processing, and visualization technologies provide viable solutions for the documentation of archaeological heritage and material culture. Work at the UNESCO World Heritage site of Çatalhöyük has demonstrated that new digital approaches for capturing, processing, analyzing, and curating stratigraphic data in 3D are now feasible. Real-time visualization engines allow us to simulate the stratigraphy of a site, the three-dimensional surfaces of ancient buildings, as well as the ever-changing morphology of cultural landscapes. Nonetheless, more work needs to be done to address methodological questions such as follows: can three-dimensional models and stratigraphic relationships, based on 3D surfaces and volumes, be used to perform archaeological interpretation? How can a 3D virtual scenario become the interface to cultural data and metadata stored in external online databases? How can we foster a sense of presence and user embodiment in the simulation of ancient cities and archaeological sites? This article aims to provide viable solutions to the methodological challenge of designing a comprehensive digital archaeological workflow from the data acquisition and interpretation in the field to a three-dimensional digital data curation based on interactive visualization, searchable 3D data, and virtual environments. This work describes the results we achieved developing the application Dig@IT, a multi-platform, scalable virtual reality tool able to foster archaeological data analysis, interpretation, and curation in a realistic and highly interactive virtual environment. 相似文献

Most quantitative approaches to distributional analysis in archaeology assume a homogeneous study surface that is amenable to easy generalisations. This framework has been widely used to describe settlement processes, disregarding the spatial heterogeneity inherent to geographic reality. In other words, researchers have often assumed that the correlation between the elements of a spatial distribution is a function of the Euclidean distance (i.e. straight line distance) between them. Other archaeological studies have tested alternative measures to Euclidean distances, such as cost-based ones, both to describe optimal routes and to assess spatial autocorrelation in a point pattern. Nevertheless, until now there has been no suitable model to introduce these measures into spatial statistical equations. In order to overcome this obstacle, we approach the implementation problem inversely by embedding the spatial pattern under study into a Euclidean frame of reference based on its cost-distance pairwise matrix. This paper describes the application of this methodology on one of the main tools used by archaeologists to assess settlement patterns: Ripley’s K function. We present two case studies, covering both macroscale and mesoscale, with significant variations in the results depending on the use of the Euclidean or cost-based approach. Data, functions and results have been R-packaged for the sake of reproducibility and reusability, allowing other researchers to build upon our methods. 相似文献

Measuring the pace of cultural change, and understanding its determinants is a fundamental goal of anthropological research. The archaeological record is the main source of information about the pace of cultural change, but it is an imperfect one, as taphonomic loss and mixing distort rate measurements. Here, I focus on the impact of time-averaging on rate measurements. Time-averaging arises when archaeological materials associated with activities and events that took place at different points in time are mixed into the same unit, whether because of depositional processes, disturbance factors, or because archaeologists lump together archaeological contexts when creating analytical units. I use analytical models to show how time-averaging can slow down the observed rates of change under two general modes of cultural change: random drift and directional change. I test this prediction using empirical rates of change from the archaeological record of North America. I show that empirical rates of change are indeed inversely correlated with the duration of time-averaging and provide a range estimate for this correlation. 相似文献

This paper deals with the presence of Sámi in central and southern Sweden in the seventeenth century. The Nordic countries have generally been believed to be ethnically homogeneous, with the** colonial subjects not being present in the center of these empires. If the multicultural aspects of early modern Nordic countries are at all discussed, Sámi and other ethnic groups are understood as peoples living on the outskirts of the empires. This notion has cemented an idea that cities such as Copenhagen or Stockholm were inhabited solely by peoples from southern Scandinavia and the continent. Drawing on the experience of the role and presence of indigenous people from the Americas and the Arctic in cities such as London in the seventeenth century, this paper examines the multi-ethnic aspects of early modern Stockholm, capital of Sweden, as an imperial center. 相似文献

The prisoners of the former concentrations camps were supposed to be deprived of their socialization by brutal dehumanization. Among other things, the use of blue-and-white striped prison clothes was meant to reinforce a homogeneous and uniform prisoner society. However, studies from a sociological perspective have shown that prisoners’ societies were indeed diverse and structured, allowing individuals to develop strategies of survival within their – albeit limited – scope for action. In this article, prisoners’ possibilities to act are discussed using the example of clothing – an omnipresent and visible medium. Various changes and alterations preserved in prisoner clothing from former concentration camps reveal open or secretive acts of individuals and thus provide insights into the different levels of action inside the camps. 相似文献
