Special buildings used as saunas have been found in certain large hillforts in the north of Portugal and in the Cantabrian coastal area of Asturias and Galicia in Spain. The principal aim of this study is to highlight the importance of these buildings in the archaeology and art of the European Iron Age, where they are very rarely mentioned. Two approaches are developed: in Parts 1 and 2, we explain the structure of the buildings, their function, and the current debate surrounding their dating. In Parts 3 and 4, further analyses are developed on their position in the landscape, associating the saunas with the public life of the hillforts, and on the decorative structure of the pedras formosas (‘beautiful stones’) found in some of them, and their relation to certain artistic trends in so‐called Celtic art.  相似文献

ABSTRACT

Although it may be thought that the rehabilitation of historical structures is a concern of modern engineering, studies on intervention processes from the past allow us to understand that this is a work carried out frequently and sometimes as a solution to low budgets for the construction of new buildings, or the need to offer quick practical solutions. The objective of this article is to show the way in which during the second half of the 18th century several important architectural and structural rehabilitation works were carried out in the walls of Cartagena de Indias, in view of the damage caused by the enemy attacks to the city as well as continuous impact by nature. By making use of primary sources (plans and original reports), the way in which two of the interventions were executed can be reconstructed: one on the Muralla Real, and another on the San José bastion, gathering information that helps explain their current state of conservation.  相似文献

Fine, polished abrasion of teeth provides evidence for use of traditional oral hygiene practices in 32 fragmentary dentitions from a cemetery for newly arrived enslaved Africans who died before leaving Valongo, the slave port and market of Rio de Janeiro. We infer that chewing sticks were used before these people were enslaved. Cosmetic dental modification and abrasion of tooth roots occur in some individuals. High caries frequency, tooth loss and hypercementosis characteristic remains of enslaved Africans with longer residence in the New World were not found in this unique collection. We review evidence that the practice of using chewing sticks persists in some regions of the Americas. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

The aim of this paper is to extend the range of current analytical procedures that archaeologists use to understand movement. In particular, how a landscape becomes ordered by simply defining a destination. More specifically, this study proposes the derivation of a focal mobility network, i.e. the network of most likely paths towards a given destination, and explores several of its applications within a landscape archaeology framework. The suggested extensions are based on existing standard procedures within most GIS. A series of synthetic control surfaces and an archaeological study focused around Iron Age hillforts in Galicia (NW Spain) are used as case studies to illustrate different analytical possibilities.  相似文献

Hydrodynamic sorting is a taphonomic process able to transport and scatter bones deposited in archaeological and paleontological sites. This study presents the results of experimentation performed in an artificial flume with guanaco (Lama guanicoe) bones of different ontogenetic development, dry and saturated in water, in hydric flows velocities of 15 and 30 cm/s. The obtained results show that bone global density, the age of the individual, the dry or wet bone state, and the hydric flow velocity influence significantly bone dispersion. In this way, bones from immature individuals with unfused secondary growth centers and relatively low bulk density have better possibility of being transported than fused bones from adult individuals. Taking into account the results obtained in this experimentation and the feasibility of discriminating age categories in fossil assemblages, two bone groups with differential potential transport are presented in this paper. These transport groups constitute a methodological tool to evaluate the role hydric current may had played in the formation of a fossil assemblage.  相似文献

The notion of path dependence has not yet been well explored as a tool for analysing landscape change. Within geography it is primarily economic geographers who have, up until now, shown a keen interest in this concept which stresses the role of social agency and institutions in understanding the development trajectories of regions. Further, the notion of path dependence usefully captures the idea of contingency in historical sequences. This article presents such a perspective on landscape change analysis, discussing two dominant types of sequences in path‐dependent systems. Self‐reinforcing sequences characterize the formation and long‐term reproduction of a given institutional pattern, while reactive sequences describe chains of temporally ordered and causally connected events. From a landscape point of view, by the former we can describe the fixity of practices, by the latter the particular development of (or changes in) landscapes. Within such a framework of path dependence analysis, examples from south‐eastern Latvia, the historical region of Latgale, are used to account for the institution of partible inheritance and to explain its impact on landscapes. The landscape biographies of two villages are studied in order to understand the particular key breaking points and the (series of) reactions that follow from these events. The challenge of using the tool of path dependence analysis lies in its openness for various interpretations, suggesting the need for supplementary theory.  相似文献

We present results of osteological and isotopic analyses of human remains from Cova de la Pastora (Alcoi, Alicante, Spain) and discuss the implications in light of a new sequence of radiocarbon dates indicating that the cave was used as a burial site in the Late Neolithic (ca. 3800–3000 cal BC), Chalcolithic (ca. 3000–2500 cal BC), Bell Beaker Transition (Horizonte Campaniforme Transicional - HCT; ca. 2500–2200 cal BC) and the Bronze Age (ca. 2200–1500 cal BC). Similarities in stable isotopic values of C and N indicate little variation in subsistence between men and women, and a similar nutritional base from the Late Neolithic to the Bronze Age. This pattern of stability is augmented by evidence of trauma and disease found on numerous skulls in the collection. Since no clear associations of specific grave goods with certain individuals based on sex or age could be determined, the only suggestion of social inequality lies in the burial practice itself, where certain individuals were interred in caves while others were not.  相似文献

The human ethics issues surrounding the conduct of health science research have been the subject of increasing debate among biomedical and social science researchers in recent years. Ethics procedures in health‐science research are typically concerned with protecting anonymity and confidentiality, and are tailored to work that primarily uses quantitative methodologies. For qualitative research in the health social sciences, a different set of ethical issues often arises in the research process. This article examines three case studies of qualitative researchers working with Indigenous Australian communities, focusing on the researchers’ experiences with ethics committees and how they approached a range of ethical issues arising in the course of their research. Key issues include: obtaining informed consent for participant observation; the evolving nature of qualitative research; the difficulties in foreseeing changes in approach; and the distinction between the research team and the researched in participatory action research.  相似文献

ABSTRACT

For many European rural areas, the rural development programmes based on the LEADER approach constitute the main policy for promoting tourism. Going a step further than a rural development programme, LEADER represents an ideal method for overcoming some of the challenges involved in rural tourism development, such as the integration of tourism supply through public-private organizations or the coordination of multi-level policies. Despite its potential, there are difficulties involved in putting this approach into practice. This article aims to provide in-depth understanding of the challenges faced by some managers responsible for developing tourism strategies through the LEADER approach. To do this, semi-structured in-depth interviews have been held with Local Action Groups managers from Castilla-La Mancha (Spain). The main findings reveal that the actions of regional governments lead to the limitation and strangulation of the principle of subsidiarity according with the LAG manager? opinion.  相似文献
