Small angle neutron scattering and neutron phase analysis techniques have been for the first time jointly employed to extract microscopic parameters of ceramic samples prepared under controlled conditions, in an attempt to establish a protocol for deriving information on the firing process. Data have also been collected on two series of early medieval samples from the Italian regions of Cuma and Miseno. The variation of the microscopic features observed on these samples could mirror some technological evolution in the period spanning from the 6th to the 12th century AD.  相似文献

El Mirón is a large cave in the Cantabrian Cordillera of northern Spain that presents a long archaeostratigraphic sequence radiocarbon-dated by over 60 assays to between 41,000 and 2000 BP. The sediments, collected from four areas within the cave and sieved-washed with fine wire meshes, contain microvertebrate remains of fish, frogs, lizards, birds and mammals, of which the latter are most abundant. Preliminary taphonomic analysis suggests that the microvertebrates were naturally collected by owls and (less) small carnivores. Small mammal assemblages are useful for palaeoenvironmental reconstruction because they are linked to particular habitats and are sensitive to environmental changes. The small mammals from El Mirón are ideal for this because sample sizes are large, bone preservation is good, and the stratigraphic sequence is long. In this paper we reconstruct the late Quaternary environments in the Cantabrian region of Spain using small-mammal assemblages from El Mirón Cave. On the basis of the ecologic adaptations of this suite of fauna, the majority still extant, we have identified seven habitat types, which are plotted through time. The evolution of the small mammal assemblages at El Mirón reveals seven major climatic shifts that correspond closely to the climatic changes recognized in the Iberian Peninsula during the last 41 kyr.  相似文献

The value of communications skills in geographical education is briefly discussed. In particular the lack of interview and interviewing practice is noted. The use of realistic interviews as part of small-group project work has been developed at Salford over 10 years. The elements include the drafting of job and person specifications, the writing of a cv and covering letter, and the organisation and running of interview panels. Detail is given of how the whole process is assessed. Negotiation skills are also developed. An important element is the realism of the process. The principal down-side is the amount of staff time involved, but this is more than compensated for by the students' perceived value of the skills developed.  相似文献

简报首次披露了梁带村墓地西区2007年发掘的10座中小型墓的信息,据出土玉器的纹饰特征等推断,这些墓葬年代为春秋早期偏晚阶段。这批等级较低的墓葬普遍有棺椁或单棺作葬具,但均不随葬陶器,而有少量玉器的现象在其他地区同时期的墓地是非常少见的,从另一层面揭示了周代芮国墓葬的突出特点。中型墓多有铜翣及串饰也较有特色,是研究周代墓葬制度的重要资料。M18出土铸有"虢季"字样铭文的铜鼎,则反映出芮国与虢国的联系交流情况,或可印证有关文献的记载。  相似文献

The valley of the River Tjonger, situated in the Province of Friesland (the Netherlands), is rich in prehistoric organic remains. The fill of the valley, consisting of waterlogged sediments (peat, gyttja and sands), presents favourable conditions for the preservation of bone, antler and botanical remains. Numerous bones with chop and cut marks, in majority of aurochs (Bos primigenius), are known from several locations in the valley. The Late Mesolithic (ca. 8000–5500 BP) is especially well represented. In this paper we present a recently discovered small hunting and butchering wetland site dating to the Late Mesolithic. The site, named Balkweg, represents a single hunting and primary butchering event pertaining to a small female aurochs with a height at the withers of 134 cm. The morphology of the vertebrae and the phalanges as well as the Late Mesolithic date confirm the identification as an aurochs cow. Single event sites are underrepresented in the archaeological record due to their small size and poor visibility. The importance of aurochs hunting during the Mesolithic is discussed in this paper as well.  相似文献

In the Iberian Peninsula, leporids, and specifically rabbits, play a key role in the understanding of hunter-gatherer economies. They appear to have been especially important in the Tardiglacial, when large numbers of small prey animals and of the European rabbit (Oryctolagus cuniculus) in particular, are a ubiquitous feature of faunal assemblages from archaeological sites. Since a large number of non-human predators can also contribute to the formation of such assemblages, the ability to discriminate between bones accumulated by humans and by other kinds of predators is a key prerequisite to their interpretation. On the basis of systematic actualistic studies carried out on modern leporid remains produced by mammalian terrestrial carnivores, nocturnal and diurnal raptors, and humans, we identified diagnostic taphonomic indicators of the different predators. In this paper, the patterns observed on the modern material are applied to the taphonomical analysis of two archaeological samples of rabbit and hare remains from Mousterian and Solutrean layers of Gruta do Caldeirão, a cave site located in Central Portugal. Our results suggest that Eagle Owl (Bubo bubo) were mainly responsible for the Mousterian accumulations, whilst the Solutrean ones were most likely the result of human activity. These data support the notion that, in Iberia, significant reliance on rabbits does not become a feature of subsistence strategies until later Upper Palaeolithic times.  相似文献

Small and medium-sized cities represent the backbone of the European territory, promoting cohesion and an economic base for development. The study compares the spatial and temporal trajectories of land use in three small/medium-sized cities located in central Portugal, between 1958 and 2011. The cities of Viseu, Leiria and Castelo Branco were chosen because they are located in different urban sub-systems and because of the different factors that frame their alterations in land use, occupation and consequent urban development. The research evaluates the transformations, supported by indicators to explain the spatial dynamics of losses and gains and a principal component analysis compares the land-use trajectories for the three cities. The general results reveal an increase from the central part of the study areas to the periphery, contrasting with a continuous decrease of the agricultural parts, illustrating peri-urbanization and rururbanization processes. The study allows identification of the dynamics in the three analysed areas, highlighting the different rhythms of change and relating them to the particularities that exist in each city. The methodology represents an advantage for the analysis and evaluation of territorial dynamics related to land-use change, and made possible the identification of the different forces.  相似文献

Postcolonial Indian women novelists writing in English have been deeply concerned with addressing the ways in which ‘home’ in patriarchal societies is an ambiguous space, characterized by unequal gender relationships that make it a terrain rife with violence, and feelings of alienation and discontent for women. Through the lens of two contemporary Anglophone novels by Indian women writers, Arundhati Roy’s (1997) The God of Small Things and Manju Kapur’s (2006) Home, this article evaluates the significance of the relationship between male identities, politics and domestic spaces in India. Focusing primarily on two bourgeois male characters, Estha and Vicky, the article examines, in depth, their painful coming-of-age in terms of the complex intersection of gender, class and age hierarchies in the domestic arena and demonstrates the centrality of the concept of home to their sense of self and space.  相似文献

Small shops are a curious paradox. When small shops are mentioned, the independent retailer is often brought to mind. Yet, many small shops are operated by multiple retailers. Given the multiple expansion, there is a need to understand the roles and problems of the independent small shop in Scotland. Whilst Scotland may be no different in this regard to other parts of the UK and the world, its geography and new Parliament might suggest new solutions. This paper examines the roles and problems of the independent small shop before examining some of the solutions adopted in particular rural areas. A plea for a better understanding of such retail facilities is made.  相似文献

两次鸦片战争期间,清朝政府将欧美小国与欧美列强“一视同仁”,宁愿让欧美小国享受欧美列强从清朝攫取的除割地赔款之外的种种特权,也不轻易满足欧美小国提出的符合近代国际惯例的一些要求.这样,清朝对欧美小国的外交也不断丧权辱国.究其原因,在于清朝以传统的“天朝上国”思想来指导近代对欧美小国的外交;清朝对欧美小国外交的最主要目的,是为了维护“天朝上国”的体制,而不是保护近代意义上的国家主权.  相似文献
