Measurements of twelve new samples of Danish Bronze Age wool showed them to be hairy medium fleeces. Supporting evidence was obtained that a high proportion of fine fibres in a yarn results from the plucking of wool during the moult before the hairy fibres have been released from the skin. The fine fibres were closer in diameter to the underwool of the wild ancestor than to those of the Soay sheep (supposedly a Bronze Age survivor), indicating a more primitive fleece. The samples described include the first white Bronze Age wool. Those with natural pigmentation in every fibre could be black or brown, while those with pigmented and white fibres are thought to be a mixture of brown and white (by analogy with the Soay) rather than grey, which is unknown in the Soay. 相似文献

Using incremental patterns in tooth cementum is a powerful tool for age assessment. Recent developments have shown that the method has a large potential as an indicator of the season of death of the individual in question. In this paper, the results of a study comparing thin sections of teeth of the modern Hardangervidda reindeer population to those of Iron Age, eleventh, and thirteenth century reindeer hunting stations from the same area are presented. The tooth wear stages were compared to the actual age of the individual (based on the number of incremental lines and the age at eruption). It was established that in the studied reindeer populations wear stages sometimes result in too low an age estimate. Having identified the start of the period of deposition for rest lines in the modern reindeer population as early autumn and winter, analysis of the outermost layer in the tooth cementum at the archaeological sites points to a prolonged hunting season in the thirteenth century, while in the earlier phases hunters were probably present on fewer and shorter visits. 相似文献

AbstractBercy is a prehistoric village sited by the Seine river (Paris, France), whose main period of occupation was dated to the very beginning of the 4th millennium BC. The animal subsistence economy relied heavily on cattle husbandry, complemented by other species including sheep. Cattle and sheep isotopic history (δ13C, δ18O) was investigated at the seasonal scale, through sequential sampling in tooth enamel, providing new insights into seasonality of birth and diet. Sheep were lambing in mid-spring, only slightly later than expected from what is observed nowadays in temperate Europe at similar latitude. Cattle were born over a period spanning approximately six months, which was an unexpected result compared with a two to three months calving period in free-ranging cattle populations. The extension of the calving period might have been related to seasonal food supplementation. Some cattle and some sheep fed on a 13C-depleted resource in winter, potentially leafy fodder. A direct consequence of an extended calving period would be the availability of cow milk, which would have covered the whole year at Bercy. This is important information in a context where the exploitation of cattle milk by the human community was highly suspected from the demographic management of the herd. 相似文献

Estimating sex ratios of fossil bone assemblages is an important step in the determination of demographic profiles, which are essential for understanding the palaeobiology and palaeoethology of any particular species, as well as its exploitation patterns by humans. This is especially true for ibex (Capra ibex), which was a main source of food for hominids during Pleistocene times. Classical methods for determining sexual dimorphism and sex ratio, such as analyses using uni‐ and bivariate plots, are based on an arbitrary fixing of limits between sexes. Here we use a more robust statistical method termed mixture analysis (MA) to determine the sex of postcranial remains (long bones, metapodials and tarsals) from ibex. For the first time, we apply MA to both a modern and a fossil sample of one species, by using metric data taken from (i) a collection of present‐day ibex skeletons and (ii) a Palaeolithic sample of the same species. Our results clearly show that the forelimb (humerus and radius) is more dimorphic than the hindlimb (femur and tibia) and is therefore better suited for sexing ibex. It also appears that metapodials should be used carefully for estimating sex ratios. On the basis of these results, we propose a classification of bone measurements that are more or less reliable for sexing ibex. The results of MA applied to the ibex fossil bones from the Upper Palaeolithic site of the Observatoire (Monaco) lead us to the conclusion that this assemblage consists of a majority of males. The quantitative estimations calculated by the MA make it possible to compare the size of Pleistocene and modern ibex for the whole set of variables used in this study.

Animal bone assemblages from four historical sites in eastern Massachusetts are analysed in a comparative framework to interpret aspects of urban food systems. Characteristics of the urban environment and the nature of food supply and exchange systems are interpreted from taxonomic representation, body part representation, butchery patterns, and age and seasonal slaughtering patterns. These analyses show that specialized husbandry to supply urban markets was limited during the seventeenth and eighteenth centuries, and that many aspects of urban food distribution systems followed traditional rural patterns. A model that explores the relation between patterning of bone collections and characteristics of urban areas is applicable to other studies of urban assemblages. © 1997 by John Wiley & Sons, Ltd. 相似文献

AbstractThe importance of materials R&D to a modern economy, which arises because of the global competition between manufacturers and the essential maturity of all manufacturing industries, is illustrated with direct examples from the semiconductor industry. One result of this R&D is that the consumption of materials per capita decreases as the wealth per capita increases. The development of the materials work at the UK National Physical Laboratory since its foundation is then briefly reviewed, together with its development to meet modern demands. The resulting sophistication in the R&D demanded is illustrated and the link to computer assisted modelling, together with the necessity for extreme precision of input data, is emphasised. The type of materials work most intimately connected with maintenance of standards and metrology is then demonstrated. 相似文献

The prevalence of digital image analysis in studies spanning a wide range of fields makes the importance of set-up design decidedly important for repeatability and testing between studies, especially for those interested in the analysis of microscopic properties. This note outlines some important guidelines for setting up an image analysis protocol, and provides a case study based on the digital analysis of dental cement. Our method allowed for us (1) to get data through the conversion of optical luminance into numerical values and (2) to accurately measure image features through numerical analysis. 相似文献

This paper introduces improved methods for statistically assessing birth seasonality and intra‐annual variation in δ18O from faunal tooth enamel. The first method estimates input parameters for use with a previously developed parametric approach by C. Tornero et al. The second method uses a non‐parametric clustering procedure to group individuals with similar time‐series data and estimate birth seasonality. This method was successful in analysing data from a modern sample with known season of birth, as well as two heterogeneous archaeological data sets. Modelling indicates that the non‐parametric approach estimates birth seasonality more successfully than the parametric method when less of the tooth row is preserved. The new approach offers a high level of statistical rigour and flexibility in dealing with the time‐series data produced through intra‐individual sampling in isotopic analysis. 相似文献

Destination image is the cumulative product of individuals processing information about a destination over time. This image comes from different sources, like media articles intended to inform a general audience and promotional materials intended to persuade potential tourists to visit. Various aspects of a destination can provide the focal point for its image, including its unique foods. With the growing interest in food in the media and in tourism, the image of places around the world is increasingly centered on this topic. Peru offers a timely case study to investigate this issue; in recent years, it has gained an international reputation as a culinary destination. The research discussed in this paper examines both popular media articles and official tourism promotions to understand the devices used to construct Peru as a culinary destination. It uses quantitative and qualitative content analysis of magazine and newspaper articles targeted at an American audience and the U.S./English version of the Official Travel and Tourism Portal. This research finds that the image of Peru as a culinary destination is consistent between sources, but there are some differences in the meanings of this content based on type of source, intended audience, and expectations about that audience. 相似文献

The technique of growth-line analysis is used to examine seasonal growth patterns in modern specimens of the edible cockle, Cerastoderma edule L. The modern control work provides a basis for the interpretation of seasonal collection in archaeological cockles, and is applied to shells from the Mesolithic site of Morton, Fife. The seasonal use of the site is shown to be clearly related to site function. 相似文献

In the present study a simple method is described for obtaining 3D digital models of petroglyphs of different sizes and characteristics and its usefulness, in the study of this cultural heritage, is evaluated. For this research we used low-cost photogrammetric software and consumer-grade digital cameras, without any other surveying techniques. In order to test this methodology, three field research studies were carried out in Galicia (Spain). 相似文献

Digital Imaging Analysis has been proposed as an efficient alternative to traditional petrography for some applications. This paper tests that proposition in the measurement of temper size and abundance in four pottery thin sections from the Pevey Site, Mississippi. The findings of both studies are presented here and the relative merits of the two techniques are evaluated in terms of accuracy, precision, cost, and time. 相似文献

This paper evaluates the effectiveness of incorporating digital video into a traditional Cook's Tour as part of a 7-day road trip around the east coast of New Zealand's North Island over a 4-year period. Student-generated video diaries summarized landscape features and processes at fieldsites, empowering students through active learning and small group collaborations. Student response was assessed via pre- and post-fieldtrip questionnaires, focus group and video diary reflection. Marks were analysed before and after the introduction of on-site student video production. Results of this research indicate the positive influence and statistically significant effects of this approach on student learning. 相似文献

Rock art paintings, and in general mural paintings, are one of the many elements of cultural heritage complex systems. As the different elements of a system have diverse spatial positions, spatial recording allows understanding their interactions. Thus, a useful approach to mural paintings recording is to understand it as a microcartography issue, managing each element of the system as a cartographic coverage. 相似文献

This paper presents and tests a model designed to investigate how off-site herd management developed in settled pre-historic societies. The model is constructed from data collected from traditionally raised local sheep, acting as an interpretive link to published data. The modern comparator was small, but plausible results allow modelling of the archaeological data to be explored. Birth seasonality and herding location are identified through modelled patterns in oxygen isotope data in tooth enamel, and diet just before death by microwear in the same tooth. In combination, these allow aspects of seasonal management of breeding, fallow and slaughter herd sections to be interpreted. Novel practices are discussed in comparison local wild sheep ethology. The case study is Neolithic Çatalhöyük (7400–6200 cal BC) in central Anatolia. Its location provided the opportunity for different parts of the landscape to be used for herding, although choice might have been socially constrained. Data are taken from 72 specimens; the results suggest settlement-wide preference for a suite of practices that kept herds within a day of the settlement and that maintained breeding cycle synchrony with optimal resource availability. Chronological analysis suggests birth season manipulation was tried but rejected, whilst hay or cereal fodder was introduced and became increasingly important. It is argued that herding was probably on dedicated pasture on the arable fringes rather than in closer integration on ‘garden plots’, as there is no evidence of field-edge weed diets and little evidence of adjusting the birth season to accommodate the crop cycle. 相似文献

As part of an investigation of prey vulnerability in Isle Royale National Park, MI, digital image processing techniques were used to enhance original quantitative computed tomography (QCT) film products to detail the processes of bone resorption and reformation in skeletal remains of moose (Alces alces). Integration of these two allied imaging technologies allowed analyses of pixels representing fractions of millimetres of bone. Using regression analysis, linear conversions from the pixel digital numbers (DN) to QCT Hounsfield units (HU) to actual bone mineral density (BMD) values were calculated (r2=0.99), and a scale of pixels per millimetre of bone was determined. The colour-enhanced image revealed quantifiable patterns of density, porosity and asymmetry. In addition, the procedure provided a quick but consistent methodology for evaluating numerous scans. Combining the limited use of a high-demand and expensive medical QCT scanner with a lower cost, readily available digital image processing and analysis system provides a technique for researchers to investigate the bone integrity of individual animals and populations. This method of evaluating bone density has implications for use in determining differential skeletal part-preservation in archaeofaunal studies. © 1997 John Wiley & Sons, Ltd. 相似文献

Academic conferences create an opportunity to disseminate new research, network with like‐minded researchers, and make new connections. The use of Twitter at these conferences continues to expand. This article focuses on how the Twitter data generated during conferences can be visually analysed in terms of community detection, connectivity, and information flows. Using social network analysis techniques and an online survey, the article analyses the subgroups within the entire network, their institutional affiliations, and research interest, and then focuses on the roles of the highly connected Twitter uses in the network. Through in‐depth analysis, the data revealed both how Australian geography academics use Twitter during a conference and how they cluster based on affiliations and research interest and also identified the information bridges in the social media conference network generated by using #IAG2019Hobart. The article concludes with some recommendations for further research. 相似文献
