Low representation of braincase bones in zooarchaeological assemblages suggests that skulls have been intensively processed by Levantine Epipalaeolithic foragers; most cranial elements are often unidentifiable and are considered poor candidates for quantifying crania. In contrast, the petrous bone is usually found complete, and was found to be easily identifiable to body size category. Use of the petrous bone in fossil assemblages analyses leads to better estimation of the occurrence of cranial elements, and thus of skeletal part representation. We therefore suggest use of the petrous bone for detecting bone destruction and selective transport in faunal assemblages.  相似文献

Opaline phytoliths are important microfossils used in archaeological and ecological research. Relatively little is known about the stability of phytoliths after burial. Under alkaline pH conditions they can dissolve, and mechanical disturbances can cause a loss of their more delicate appendages. Here we present an experimental study of phytolith stability (combination of solubility and abrasion). Modern and fossil phytoliths were extracted from wheat using new methods to minimize dissolution, and by burning in an oven. These assemblages were placed in a solution buffered to pH 10 and maintained under constant temperature and shaking conditions. The silicon concentrations in the solution were monitored once a week for 5 weeks. The phytolith morphologies in each assemblage were determined at the outset of the experiment and after 5 weeks. The results show that there are differences in stability between various assemblages. Modern inflorescence wheat phytolith assemblages are more unstable than those from leaves/stems. Burnt assemblages are less stable than unburnt assemblages, and a fossil phytolith assemblage about 3000 years old is more stable than the modern wheat assemblages. The results also show that individual phytolith morphotypes have different stabilities, and as a result of dissolution and abrasion, some morphotypes may resemble others. This study further shows that archaeological and/or paleo-environmental interpretation of phytolith assemblages may change with the assemblage’s state of preservation.  相似文献

We study a skeletal sample digested by Iberian wolf (Canis lupus signatus) in order to finding diagnostic features of digestion caused by this agent. The remains were taken from scats collected in different natural areas in the northwestern Iberian Peninsula. We tested different methods to recover the remains with the goal of not produce biases, and we evaluated the most appropriate methods. The results were compared with those reported by other authors who have also worked with samples digested by wolves. Bias during the procurement of the skeletal assemblages seems to be a significant cause of the differences observed between the samples. We found that it was necessary to fully recover all remains and individually analyze all modifications, even in small-sized remains. Taphonomic characterization was performed by analyzing physical and biochemical modifications. We believe that these results may be useful in the study of archaeological and paleontological assemblages.  相似文献

This actualistic study examines the taphonomic signatures of modern free-ranging mountain lions (Felis concolor) on prey skeletal remains left at kill sites and digested bone fragments in the lions’ scats. Conducted in western Texas and southeastern New Mexico (U.S.A.), the study and its outcomes are relevant to models of carcass persistence and scavenging opportunities on ancient landscapes. Mountain lions in the study area ingested disproportionate quantities of bone from very young prey. This tendency holds true irrespective of prey body size. The results meanwhile confirm a relatively mild pattern of damage to adult deer carcasses. Digestive erosion of the surfaces of bones that passed through the gut was relatively severe, but many of these bone and tooth specimens retained identifiable features. It is clear that the mountain lions quickly remove the carcasses of very young prey from the pool of potentially scavenge-able resources. The non-linear relation between bone destruction from feeding by the cats and the skeletal maturity of prey also has consequences for prey mortality patterns, specifically a bias against the representation of very young individuals. This effect is not sufficient, however, to produce a global bias to prime-adult prey because older juveniles are much less affected.  相似文献

Expectations for survival of vertebrate remains have been well developed and intensely studied in the zooarchaeological taphonomic literature. Taphonomic studies of shellfish remains focus on marine species and on variables relevant to remains from paleontological contexts (e.g., fossil marine beds). In this paper we develop a conceptual framework from which to derive expectations concerning the preservation of freshwater mussel remains focusing on two parameters, shell microstructure and shell shape. Shell size does not influence survivorship. Our model is validated through application to late Holocene zooarchaeological mussel assemblages from north Texas. Taphonomically robust species are important regarding zooarchaeological and biogeographic interpretations based on mussel paleofaunas, and fragile species are important indicators of whether or not an assemblage is well preserved.  相似文献

Archaeometallurgy frequently seeks to correlate between the temporal and spatial distribution of ancient metal objects and their chemical composition. In this study, we examined whether and to what extent local or temporal deviations in the content of modern artifacts can be identified as a proxy for archaeological material that is typically less controlled and therefore more difficult to cluster. For this purpose, Euro coins of 10, 20 and 50 cents from Germany, France, Spain, Italy and Belgium, which are made of copper (Cu) with 5% aluminum (Al), 5% zinc (Zn) and 1% tin (Sn), were analyzed using a simple XRF analyzer. The mass ratios Sn/Cu and Zn/Cu were measured with a relative precision c.a. of 5%. The mean content of the coins from each country was then determined for 20–39 of them. The difference of the mass ratio Sn/Cu observed – from 0.0101 to 0.0111. One coin from Luxemburg shows differences in various areas of its surface of up to a factor of 1.5. Thus, the results of this small pilot research show that even in modern metal artifacts we can detect differences in metal content, which can be correlated to their production and utilization places. Therefore, this study can serve as a model for evaluating compositional variations noted in archaeometallurgical studies where the standard deviations are greater and the differences can be linked more readily to spatial and temporal differences.  相似文献

This paper considers the possibility of overt political disagreement between human geographers and their students. Recent literature suggests that geographers should encourage their students to become more politically engaged through innovative teaching methods that could include frank discussion of the various positions taken by lecturers and students alike. Yet this same strategy could easily run against established pedagogical arguments about how teacher neutrality gives students the space to develop their views in whatever direction they choose. This paper investigates the practical management of this tension by drawing on qualitative interviews with a sample of current practitioners that centred on the occasions when personal politics have previously featured in their undergraduate teaching. It describes why overt political discussion is often squeezed out of these encounters, the careful ways in which these academics manage their political views during the times when such discussion occurs along with the degree to which they felt they should reveal them, and how students themselves commonly seemed to perform opinion in a relatively superficial way because doing so could be much less stressful. The conclusion that follows reflects on the broader implications of these findings for current debate and future practice in the discipline where it particularly emphasizes the importance of being sensitive to the interpersonal dynamics at hand.  相似文献

The author explores the reasons for the failure of a plan for population exchanges that took place between Jews and Arabs in Palestine in the 1930s. Special focus is given to the success of previous exchanges between Greece and Turkey that took place during the 1920s and why this model failed in Palestine. The author concludes that "the Zionist plans which assumed that one could encourage voluntary transfer by creating attractive economic conditions in the target areas, did not take into account the factors of nationalism, ties to place of residence, religion, etc. These factors carried no less weight than the economic factor and they could effectively prevent any voluntary transfer of the Arab population."  相似文献

Excavations at Dispilio, a prehistoric lakeside settlement in northern Greece, have revealed a significant number of vertical wooden piles that need to be protected during and after excavation. Lifting of the piles is not possible and approaches such as reburial, cannot currently be implemented as excavation is still in progress. In 2005, several posts were “selectively buried” on an experimental basis, by encasing them in PVC pipes and backfilling with the surrounding sediment. This approach appeared to be capable of protecting the piles during excavation and be a potential solution for their post-excavation preservation. This preliminary study sets out to asses if this alternative approach to reburial could be an effective in situ preservation method.  相似文献

Narrative inquiry is an innovative means of encouraging students to internalize concepts, reflect on experiences or create applications for theoretical ideas. The use of first-person creative writing in a second-year cultural geography course prompted initial scepticism from students but eventually highlighted their constructivist engagement with course concepts. Despite a number of ethical, evaluative and moral dilemmas, encouraging the use of creative writing as a form of narrative inquiry allowed students to tell their stories so that they were valued and connected to wider disciplinary concepts.  相似文献

By exploring the experiences of over a hundred child traders in Cusco, this research provides an insight into the more everyday circumstances of children's work in developing countries. The working conditions of child traders raise serious concerns, including: dangers of accidents, theft and abuse; shortage of time for play; and some disruption to education. Nevertheless, the positives of trading work are substantial. Although the children feel that they have to work, they gain enjoyment and economic empowerment. Moreover, they display a certain self esteem and confidence in the knowledge of their trading skills, and a spatial awareness of the best trading sites, demonstrating agency in their choice of trading locations. The findings suggest that international policy, which emphasises universal condemnation and prohibition of child work, requires revision. Such policy should be replaced by a more flexible approach, which recognises the benefits of children's work and embraces supportive protection for children engaged in the lighter forms of work such as trading.  相似文献

Differences in labour force participation and unemployment rates between indigenous populations and immigrants are common throughout Europe, but the gap seems to be particularly wide in Sweden. Based on studies of workplaces that traditionally employed large numbers of immigrants, but where they are now declining, it is argued that a driving force behind this process of exclusion is to be found in technological and organisational changes. These changes seem to be more pervasive in the Swedish labour market than in other economies in Europe. What is sometimes called the ‘Swedish model of working life’ has turned into the systemic exclusion of immigrant labour.  相似文献

Although trephination of sub-adults in antiquity is rare, scurvy both infantile and adult, is even more rare in the archaeological record. Pathological changes appearing in the maxilla, mandible and orbits of a child of 8–9 years of age are highly suggestive of infantile scurvy. Advanced forms of this metabolic disturbance lead to severe subperiosteal haemorrhaging, at times turning the skin of the face and skull black. This condition may have led to the trephination along the sagittal suture as a form of blood letting in hopes of draining the subperiosteal haemorrhage in the cranium. Although cause and effect are often confusing in antiquity, the surgical intervention presented here led to the ultimate death of the child.  相似文献

The archaeological discovery of bituminous coal in the tipple area and the subsequent analyses of specimens of the iron ore, charcoal, limestone, slag, and cast iron from the Eaton (Hopewell) blast furnace built in 1802 indicate that raw coal was used in combination with charcoal as a fuel in American iron smelting at least thirty years before it was used alone. Further, its use in this combinatory manner marks the earliest as yet attested to in the New World.  相似文献

Abstract

The March First Movement and the May Fourth Movement are like mirrors reflecting each other’s relationship. This article uses the concept of “simultaneity” in global history to reevaluate the significance of both events in world history. It also examines the differences exhibited by the simultaneity of the two events from the perspective of an “interconnected East Asia.” After entering the world-system, imperial Japan, semi-colonial China, and colonial Korea occupied different positions within its hierarchical structure. Here we need to pay attention to the status-diverse but mutually influential conditions in East Asia. To see through the complexity of (semi)colonial modernity and find the inherent opportunities to overcome modernity, it is useful to analyze the “double project” of adapting to modernity and overcoming modernity. Since the 1920s, the two events have been continually reinterpreted in the vein of socio-historical changes. The question of how to remember the two is not only a historical question but also a practical question for the present. Now is truly the methodological turning point in exploring and reinterpreting the two events. The author will use the terms “March First Revolution” and “May Fourth Revolution” in an attempt to tackle this issue. The mass gatherings that took place during March First and May Fourth provide sufficient evidence to support the use of “revolution” to describe them. Although March First and May Fourth are part of two respective histories of Korea and China, at the same time they are part of East Asia’s and the world’s interconnected history.  相似文献

Natron deposits, the best known of which being those at Wadi Natrun in Egypt, have been used as the flux in the production of vitreous materials from the early 4th millennium BC onwards. In the present paper, the history of the use of natron as a flux is traced from its beginnings in the glaze of Badarian steatite beads, through its use in glass production starting in the 1st millennium BC, until its apparent shortage during the 7th to 9th centuries AD, and its subsequent replacement by plant ash during the 9th century AD. Documentary evidence for possible natron sources in Egypt, including the Wadi Natrun, and around the eastern Mediterranean is summarised, and the results of recent fieldwork at the Wadi Natrun and at al-Barnuj in the Western Nile Delta are presented. The possible reasons for the apparent shortage of natron from 7th to 9th centuries AD and its subsequent replacement by plant ash as the flux used in glass production during the 9th century AD are then considered. These include the possibility that, because of the massive scale of glass production, the demand for natron exceeded its supply; the possible effect of climatic changes; and the potentially disruptive role of political events in the Wadi Natrun–Delta region.  相似文献

After the last Holocene sea level rise (about 6900 BP), the Gulf of Tartessos extended over the south-western area of the nowadays Guadalquivir Valley (Spain). With the development of some depositional littoral landforms and the progressive infill, the system evolved towards an inland lagoon. The first political system in the area emerged and collapsed from the fourth to the second millennium BC. Around the first millennium BC the culture of Tartessos flourished in this area under the Phoenician influence, but it vanished by the sixth century BC. The quest of its lost capital, the city of Tartessos, has been one of the most exciting archaeological enterprises in the past century. The former coastline and the bathymetry of the gulf can be reasonably reconstructed from geo-archaeological studies, and it can be used for the numerical modeling of tide and tsunami propagation in this water body. Models, with a spatial resolution of 30 s of arc, are based on the 2D non-linear hydrodynamic equations and have been previously validated under nowadays conditions. Computed tidal elevations and currents can provide some insight on the ancient trades for ship traffic and fisheries. The simulation of tsunami propagation, like the catastrophic one of 1755, allows estimating their potential hazardous effects on ancient coastal cities.  相似文献

Human geography students face changing qualification requirements due to a shift towards new topics, educational tasks and professional options regarding issues of spatial development. This ‘practical turn’ raises the importance of inter- and transdisciplinary work, management and capability building skills, with case study projects and student-centred learning providing suitable approaches. This paper introduces the example of the teaching and research project ‘Leben 2014’: Students, faculty and local actors have collectively worked out future development scenarios for a rural region in Austria, actually creating impact. The project may thus serve as a model that inspires similar schemes in other countries.  相似文献
