Personal appearance in general—and the grooming of hair in particular—has long held a position of interest in historical, art-historical, and literary scholarship. The same cannot be said of archaeology, and the material aspects of personal grooming in the construction and communication of identity have not been fully synthesized. As a result, little attempt has been made to understand the social role of hair in less well documented societies, such as those of early medieval northern and western Europe. This paper considers archaeological, iconographic and documentary evidence for the significance of, and physical engagement with hair in early medieval northern and western Europe, and offers a model for the interpretation of grooming as a social phenomenon. It is argued that grooming was a socially meaningful practice, and that it played a key role in the construction of early medieval identities, as well as in the maintenance and manipulation of boundaries and distinctions between individuals and groups. 相似文献

Based on an ethnographic field investigation conducted on the matrilineal–matrilocal Garo community of Bangladesh, this article provides a historical account of local environmental struggles to draw attention to the interconnections between gender, environment and sustainable resource management. From a feminist political ecology perspective, the article argues that interacting with traditional culture, forest ecology and changing processes of centric resource governance, gender remains a salient variable in environmental issues. Local contexts of gender dynamics help configuring local people's mode of participation in environmental struggles as well as being the consequence of those struggles. Findings suggest that Garo women and men have sustained gender specific roles and interests through their struggles to ensure control over forest lands and tree resources. Furthermore, they have developed a class-based relationship with forest ecology which must be acknowledged in forest policies. 相似文献

In this paper we show the results of a study concerning 42 axes, mainly discovered in the Copper Age pile dwellings of Ljubljansko barje (central Slovenia) and in the neighbouring areas of Caput Adriae. The studied shaft‐hole axes, characterized by homogeneous typology but slightly different raw materials, have been called ‘Ljubljana‐type’ axes (Lt). The raw materials show a common OIB‐like signature and metamorphic and spilitization features that recall oceanic conditions. The typological and geochemical characteristics and the very high percentage of Lt axes among the polished stone axe assemblages of Ljubljansko barje suggest that the raw material was probably gathered from one or more relatively small outcrops close to Ljubljansko barje. Similar igneous rock types outcrop in the presumably Palaeozoic diabase/shale complex (Eisenkappler Diabaszug), intruded by the northern Karawanken plutonic belt. A probable provenance from this area, particularly rich in copper ore deposit, would confirm the important role of Ljubljansko barje as a metallurgical district, as well as a strong relation between lithic raw materials and Cu cultivation districts during the Copper age. 相似文献

Multi‐isotope fingerprinting (sulphur, oxygen and strontium isotopes) has been tested to study the provenances of medieval and Renaissance French and Swedish alabaster works of art. Isotope signatures of historical English, French and Spanish alabaster source quarries or areas are revealed to be highly specific, with a strong intra‐group homogeneity and strong inter‐group contrasts, especially for Sr and S isotopes. The chosen combination of isotope tracers is a good basis for forensic work on alabaster provenance, allowing verification of hypotheses about historical trade routes as well as identification of fakes and their origin. The applied analytical techniques of continuous flow isotope ratio mass spectrometry (CF–IRMS) and thermal ionization mass spectrometry (TIMS) only require micro‐samples in the low‐milligram range, thus minimizing the impact on the works of art. 相似文献

On the East coast of Tunisia, between Sousse and Sfax, lie the scant remains of the ancient city of Thapsus, notable mainly for a battle fought in the civil war in 46 BC. Visits by the authors resulted in the discovery of one of the longest‐known harbour moles in the entire Roman Empire. No ancient sources make reference to any work of such magnitude and the paper suggests that the harbour was never completed, but might have been started by the local emperors Gordianus, none of whom survived long enough to have executed such a project. 相似文献

The establishment of colonial rule by one society over another, both in ancient and modern examples, often has dramatic consequences for the establishment and maintenance of political relationships within the context of everyday life in colonial society. In this article, I examine the ways in which the performative acts of dining can play an integral role in this reconstruction of political relationships that is so often implicit in colonial encounters and state expansion. In particular, I suggest that an analysis of the ceramic evidence of vessels used in dining and the frequency of specific forms in the overall assemblages can help to reveal the ways in which the politics of commensality play an active role in transforming political relationships and strategies of power in colonial societies. This article uses the example of ancient Mediterranean France after the Roman conquest in the late second century bc at the Celtic-speaking settlement of Lattara (modern Lattes). I argue that by the end of the first century bc, coinciding with a time period when the political structure of the region was being significantly reorganized, there was a notable change in dining practices, with a move away from a more communal ethos in dining to one emphasizing the individual. These new practices served the strategic interests of individuals in local society at Lattara seeking to break with earlier political systems and integrate themselves into larger colonial society. 相似文献

The article investigates the ‘long 1970s’ (1968–82), when Hungary re-orientated its economic and foreign-trade relations. Hungary was always a promoter of a deepening of Council for Mutual Economic Assistance (CMEA) co-operation and when it noticed that socialist integration stagnated at the level of the bilateral exchange of commodities, Budapest gradually launched a policy of opening up to the world outside the CMEA. The year 1977 was a turning point in economic policy. Hungarian elites' thought and attitude towards the West changed, but not independently of the world economic crisis and its impact on Hungary. The oil crisis sharpened latent tensions, and behind the robust growth serious problems appeared. Although Hungary intensified its interrelations with the West and the Third World, the country was not able to profit from the advantages of international trade and co-operation. The article is based on state, party and senior economic leaders' archives. 相似文献

Thermohaline convection of subsurface fluids strongly influences heat and mass fluxes within the Earth's crust. The most effective hydrothermal systems develop in the vicinity of magmatic activity and can be important for geothermal energy production and ore formation. As most parts of these systems are inaccessible to direct observations, numerical simulations are necessary to understand and characterize fluid flow. Here, we present a new numerical scheme for thermohaline convection based on the control volume finite element method (CVFEM), allowing for unstructured meshes, the representation of sharp thermal and solute fronts in advection‐dominated systems and phase separation of variably miscible, compressible fluids. The model is an implementation of the Complex Systems Modelling Platform CSMP++ and includes an accurate thermodynamic representation of strongly nonlinear fluid properties of salt water for magmatic‐hydrothermal conditions (up to 1000°C, 500 MPa and 100 wt% NaCl). The method ensures that all fluid properties are taken as calculated on the respective node using a fully upstream‐weighted approach, which greatly increases the stability of the numerical scheme. We compare results from our model with two well‐established codes, HYDROTHERM and TOUGH2, by conducting benchmarks of different complexity and find good to excellent agreement in the temporal and spatial evolution of the hydrothermal systems. In a simulation with high‐temperature, high‐salinity conditions currently outside of the range of both HYDROTHERM and TOUGH2, we show the significance of the formation of a solid halite phase, which introduces heterogeneity. Results suggest that salt added by magmatic degassing is not easily vented or accommodated within the crust and can result in dynamic, complex hydrologies. 相似文献
