An efficient and non-destructive method to classify white marble artifacts by using a hand-held, portable XRF analyzer (pXRF) is here reported. The identification is based on the uniquely high strontium content of this marble and has been verified by testing 32 artifacts, most of which had already been provenanced, using conventional micro-destructive analyses. Besides strontium, other potential provenance indicators, such as manganese and iron, were analyzed and their concentration values obtained after empirical calibration of the instrument by using 17 quarry samples of known composition. The results show that Göktepe/non-Göktepe discrimination is almost always possible (30 artifacts) and that additional analyses are required only when the Sr value is at the lower edge of the Göktepe field (2 artifacts). The success of the method, however, resides in the particular composition relative to trace elements of Göktepe and is not easily extended to other marble varieties. Main reasons are related to insufficient accuracy at low concentration values, intrinsic trace variability of marble artifacts, surface effects that may produce not representative results. Interest in the method therefore is tightly linked to the exceptional importance of Göktepe as a sculptural marble, in which case, detailed data, obtained with a fast and totally non-destructive method, may provide relevant information concerning chronology, workshops, and places of production of the artifacts.  相似文献

This article contends that the global thrust towards population management, legitimised by the concept of sustainable development, works to construct identities along the lines of gender and sexuality. This article focuses on the operation of what Foucault termed, biopower, as operational through and (re)productive of the United Nation's (UN) population/sustainable development discourses. I argue that the said disciplinary narratives and apparatuses such as the construction of environmental threat and the monitoring and regulating of populations, in the service of sustainable development, work to construct gendered identities and ‘naturalise’ heterosexual relationships. To demonstrate this, this article focuses on key UN documents directed at informing international environmental/population policy, namely Agenda 21 and the International Conference on Polulation and Development's Programme of Action.  相似文献

This paper shows the results of a multidisciplinary study carried out on the mortars from the Late Roman Villa dell’Oratorio (fourth-sixth ad), an aristocratic mansion built in the lower Valdarno (Florence, Italy). Thirty-one bedding mortar and plaster samples were analysed through optical microscopy, thermogravimetric analysis, X-ray powder diffraction and scanning electron microscopy with energy-dispersive X-ray spectroscopy for determining the chemical, mineralogical and petrographic characteristics, while their main physical properties were measured by geotechnical procedures. The collected data indicates that the analysed mortars are made up of very fine to coarse river sand aggregate mixed with white to yellowish-white natural hydraulic lime binder mainly consisting of mixtures of prevailing calcite and hydraulic compounds. With regard to the origin of the raw materials, the aggregates were recognized to be selected Arno river sands, and the binders are the burning product of a local marly limestone (ex Alberese). Therefore, the mortars of the Late Roman Villa dell’Oratorio are one of the first uses of natural hydraulic lime in the lower Valdarno.  相似文献

The identification of butchery marks in the zooarchaeological record has consistently been debated. Much experimental work has been done to understand the causal agents behind some bone surface modifications, but recent controversies show that there is still no consensus. Terminology is not consistent between researchers, and there is ambiguity in how characteristics of marks are described and interpreted. There is also a lack of understanding of what causes individual variables within marks made by different agents, which is compounded by mark morphologies being described in terms that imply their causality. This paper examines these two problems in light of historic and current trends in the taphonomic literature, and recommends ways to describe marks that will facilitate more effective communication between researchers. It is proposed that greater standardisation within zooarchaeology is needed in seven key areas, and that this is the best avenue for moving into a new phase of taphonomic research.  相似文献

A 15–18 months old child mummy, presently housed in Turin's Museum of Anthropology, was discovered in Gebelein (Upper Egypt) during excavations carried out by the Missione Archeologica Italiana, most likely in 1914.  相似文献

From the early part of the eleventh century, legendary propaganda was generated by the Tosny family. The Warwickshire branch of the Beaumonts did likewise from the late twelfth century, their efforts culminating in the popular romance Guy of Warwick. Such material was designed to romanticize those activities of the families which had led to their acquiring landed power, and to reinforce a widespread acceptance of the status which they endeavoured to retain in face both of the growing powers of the monarchy, and of economic pressures. By contrast, the families of Beauchamp and Mauduit relied on growing royal power to enhance their position. Beauchamp dominance of Worcestershire through the hereditary enjoyment of the post of sheriff, and Manduit enjoyment of court influence through exercise of the hereditary office of chamberlain, obviated the need to generate a popular image, although both families attracted unfavourable notice in contemporary literature, generated by territorial or professional rivals. When the estates of all four families merged, at the end of the thirteenth century, to form the late medieval earldom of Warwick, the Guy image was consciously revived. John Rous, composing the Rous Roll in 1483, in order to glorify the lords of Warwick, suppressed unfavourable elements, both in this literature and in modern political history, while elaborating on others, reworking the material with the help of current literary themes.  相似文献

ABSTRACT

There is a norm assuming high mobility in the Western world today, which can increase the social and geographical exclusion of those who have limited possibilities to travel, such as people with disabilities. When it is a child who has the disability, travel-related constraints are likely to affect the whole family’s travel patterns. This study explores travel constraints among Swedish families with children with cerebral palsy who use wheelchairs. A time-geographical framework is employed. Interviews with parents show that these families’ everyday mobility is affected by authority, capacity and coupling constraints, and that it is often a combination of these constraints that makes travelling difficult. The families use different strategies to negotiate these constraints. In addition to strategies controlled by the families, the findings suggest that there is also a need for governmental support and a barrier-free transport system to enhance their mobility.  相似文献

ABSTRACT

Analysis of over 4000 complete left oyster valves from late medieval and post-medieval Dudley Castle reveals the changing role of this perishable luxury over a 700-year period. Throughout the occupation, it seems that oysters were used as ingredients rather than served raw in the shell. A greater reliance on oyster consumption is apparent in the later fourteenth century, perhaps reflecting a more diverse diet amongst the aristocracy in the wake of the Black Death. An increased preference for mussels and whelks is also attested in the Tudor and early modern periods, reflecting changing perceptions of these foods.

Overall, it is likely that natural beds were exploited throughout the time that oysters were being brought to Dudley Castle; however, the evidence demonstrates a shift from limited exploitation of natural inter-tidal sources in the eleventh century towards the dredging of sub-littoral beds in later periods, with some possible translocation of oyster stock. Changes in the shape, size and appearance of the oyster shells suggest the source locales from which the oysters derived changed through time. A notable shift occurred in the fourteenth century, which could reflect changes in supply brought about by altered tenancy at Dudley Castle and/or disruptions to trade brought about by the Black Death. Future biochemical analyses are recommended to provide greater clarity on the origin of those sources.  相似文献
