In skeletons excavated from Woodland sites, copper and barium levels are found to have been contaminated by influx from the soil environment. Electron microprobe scans for both elements show build-up along the outer surface of femur cross sections. Elemental levels for Cu and Ba are lower in the femur or fibula than in the more porous rib. The distribution of Cu in the immediately surrounding soil is highly anisotropic. These observations indicate that Cu and Ba should not be used for dietary inferences about ancient populations without independent evidence that diagenesis is not important. 相似文献

Fifty-one waster sherds of Terra Sigillata (~20-0 b.c. ) from Arezzo, Italy and Lyons, France have been chemically analysed for twenty-eight elements by neutron activation and seven by X-ray fluorescence. Most of the elemental abundances were measured with high precision and cross-comparisons of the two techniques of measurement (and sample preparation) give added insight as to their relative precision, the calibration differences and the extent to which volatile materials such as carbonate or water influence the results. The sherds from Arezzo formed a homogeneous and distinctive chemical group while all but two of those from Lyons were classified into three such groups. Two of the Lyons groups (MML A and MML B) were from Montée de La Muette and one was from Loyasse. Four additional sherds from houses excavated in Strasbourg and one from Lyons, all of which bore the signature of the famous Anetine pottery-making firm of Ateius, were also analyzed by the same techniques. These signed sherds all had the same composition pattern and it closely matched one of those from Montée de La Muette (MML A) in Lyons. It is therefore suggested that these five sherds bearing the Ateius signature were made in the general vicinity of Lyons and were part of the output of an as yet unknown Gallic branch of the firm of Ateius. 相似文献

The relationship between bridewealth and women's autonomy is not only discussed amongst anthropologists, development practitioners and other scholars but also amongst brides themselves. Women continue to embrace such marital exchanges, despite their knowledge of ‘modern’ development discourse about the constraints of the practice on women's status and its links to gender-based violence. This paper provides a visual exploration of contemporary brideprice practices and women's autonomy in Mt Hagen. We draw on scenes from our ethnographic film (An Extraordinary Wedding: Marriage and Modernity in Highlands PNG) to explore deliberations and developments that occurred in the case of a particular marriage that took place in 2012. We argue that the institution of brideprice has the potential to enhance the visibility of some women and the importance of their contribution to their own and husbands' kin groups. Despite current tensions regarding brideprice, it can serve as an avenue for the enhancement of women's political participation. The particular brideprice exchange featured in our film, raised concerns for the participants, which we consider in terms of three questions: Does brideprice commodify women? Does it play a role in gender-based violence? Is it inimical to aspirations for modernist individuality? We discuss the importance of bekim (‘return gift’) and suggest that this practice challenges the notion of brideprice as a commodity transaction. We argue that, while there may be an association between brideprice and gender-based violence, brideprice, in and of itself, is not causative of violence. The marriage represented in the film, and discussed in this paper, reveals the creativity of participants in adjusting the values inherent in the customary practice of brideprice to their contemporary aspirations. 相似文献

This paper presents a revised version of the Coimbra method for recording fibrocartilaginous entheses. The method itself is the only biologically appropriate recording method for fibrocartilaginous entheses that scores features separately, thereby ensuring that the aetiology of individual features can be studied. The method divides the enthesis into two zones, scoring the relevant features in each zone. These features represent either bone formation or bone destruction and include erosive lesions, fine and macro‐porosity, and cavitations. The revised method includes a new feature, textural change, which is scored as absent or present when it involves 50% or more of the surface. All other features are now scored as zero (absent), one or two with the higher score representing greater expression of the feature. This change in scoring has led to the reduction of inter‐observer error with approximately 80% agreement for overall feature scores for both the common extensor origin and subscapularis insertion. The simplification of the scores and the reduction in inter‐observer error mean that the method is now recommended for widespread use. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

This paper analyses the results of a survey of twenty-four recent cases of technology imports into India. Over the last thirty years, large firms in Indian industry have come under increasing competitive pressure from small firms which pay lower wages and which are also favoured by government policy. Most small firms obtain technology through informal channels within the country. But some import technology; and larger firms import it in their defence against competition from small firms. Larger firms, with a history and a reputation, have better access to technology from abroad; smaller firms often go through an extensive search before they find a willing technology supplier. Irrespective of size, firms that import technology within their own specialization are observed to put more effort into technology choice, absorption and adaptation. Indian policies of across-the-board import substitution, by promoting diversification into new products developed abroad, tend to discourage specialization and hence to encourage technology imports and to work against technology absorption and innovation. 相似文献

Particle-induced X-ray emission (PIXE), X-ray diffraction (XRD), electron microprobe analysis (EDS) and scanning electron microscopy (SEM) analytical techniques were used to characterize surface paints in pre- and post-fired Aguada Portezuelo decorated pottery. Surface paintings in black, white, red, brown, burgundy and ochre were analysed. Major, minor and trace elements were detected by PIXE, whereas XRD and SEM-EDS gave information on the main mineral phases and the characteristic morphology for each analysed pigment. The results obtained indicate that the main colour groups can be easily discriminated by PIXE, and they are characterized by only one pigment for each colour: hematite (red) and manganese mineral oxides (black), respectively, whereas white pigments are characterized by calcite, ghelenite and gypsum. 相似文献
