Grasslands pose a particular problem for archaeological survey involving artifact assessment, as no material is plowed up to the surface. Although finds in molehills are often the only source of information available on sites with such low visibility, an archaeology of molehills has thus far been largely disregarded. Yet, by applying a low-cost and time-efficient methodology, both the potential and the pitfalls of molehill archaeology come to the forefront. At the medieval harbor site of Monnikerede, it was possible to assess material culture and to locate certain structural elements. However, when artifact densities were compared with the underlying geophysical anomalies, a more complex relationship appeared at the level of individual features. 相似文献

The Aterian lithic techno-complex that characterizes the late Middle Stone Age in North Africa is well known especially for its tanged or stemmed points. Recent techno-morphological and use-wear analyses have added new data to support the identification of the tang as the hafted portion of an artifact. They have also highlighted the presence of this attribute on tools other than projectile points, in contrast with the widespread idea that the tanged point is the Aterian fossile directeur. The design of this specific device, the tang, for hafting purposes is regarded as a great technical innovation that underlines a modern behavior. Our work provides new use-wear and experimental data, aiming at discussing the cognitive preconditions of this technical innovation that could have originated from a specific functional unit: the notch. Notches are quite abundant in the Aterian techno-complex. Our systematic study of this tool category from Aterian sites of the Jebel Gharbi allowed defining the notch per se as a techno-morpho-functional unit that was “applied” to different types of blanks, including “reused blanks,” which show a heavy patina on their surface. This functional unit has been used for various types of activities and can be found either alone on a blank or with multiple other units on the same blank, creating different tool morphologies. According to this interpretation, the tang could have been considered by Aterian populations as a new resulting variant of various possible combinations of notches, for defining and/or transforming the shape of a tool. 相似文献

Roman plasters sampled from different houses at the archaeological site of Herculaneum, Italy, (2010–12) were studied by means of petrography, thermal analysis and X‐ray fluorescence. Herculaneum plasters are composed by preparatory layers (arriccio) with a thickness of several centimetres and are based on a calcitic binder and volcanic scoriae as aggregates, covered by a thin final layer characterized by a low granulometry. Most of the sampled plasters can be placed into two groups based on the aggregate composition and classified as marmorino or intonachino. However, a similar aggregate composition did not induce superimposable thermal behaviour, thus suggesting that the samples underwent different ageing/weathering processes, with a consequent change of the ratio among the components. 相似文献

Radon Predictions with Geographical Information System Covariates: From Spatial Sampling to Modeling 下载免费PDF全文
Radon (Rn) is a potentially toxic gas in soil which may affect human health. Assessing Rn levels in soil gas usually requires enormous efforts in terms of time and costs, since the sampling protocol is very complex. In most cases, the variable under study is sparsely sampled over the domain and this could affect the reliability of the spatial predictions. For this reason, it is useful to incorporate, into the estimation procedure, some auxiliary variables, correlated with the in soil gas Rn concentrations (primary variable) and more densely available over the domain. On the basis of this latter aspect, it is even better if the covariates are derived from a geographical information system (GIS). In this article, the Rn sampling protocol used during a measurement campaign planned over a risk area is described and the process of deriving GIS covariates considered as secondary information for predicting the primary variable is clarified. Then, multivariate modeling and prediction of the Rn concentrations over the domain of interest are discussed and a comparative study regarding the performance of the prediction procedures is presented. Rn prone areas are also analyzed with respect to urban and school density. All these aspects can clearly support decisions on environmental and human safeguard. 相似文献

Muslim active citizenship in Australia: Socioeconomic challenges and the emergence of a Muslim elite
Mario Peucker Joshua M. Roose Shahram Akbarzadeh 《Australian journal of political science》2014,49(2):282-299
The most recent national Census demonstrated that Australian Muslims continue to occupy a socioeconomically disadvantaged position. On key indicators of unemployment rate, income, type of occupation and home ownership, Muslims consistently under-perform the national average. This pattern is evident in the last three Census data (2001, 2006 and 2011). Limited access to resources and a sense of marginalisation challenge full engagement with society and the natural growth of emotional affiliation with Australia. Muslim active citizenship is hampered by socioeconomic barriers. At the same time, an increasingly proactive class of educated Muslim elite has emerged to claim a voice for Muslims in Australia and promote citizenship rights and responsibilities.
最近的全国普查显示,澳大利亚的穆斯林仍处于社会经济的弱势地位。在诸如失业率、收入、就业类型、家居拥有等关键指标看,穆斯林一直位于国家平均水平之下。这一模式在最近三次普查(2001、2006、2011)中非常明显。获得资源渠道的有限以及边缘化感觉阻碍着他们充分参与社会,以及在情感上融入澳大利亚。穆斯林的公民意识受困于社会经济障碍。与此同时,也出现了一班受到良好教育的穆斯林精英,这个积极进取的阶层开始为澳大利亚的穆斯林代言,促进他们的公民权利和义务。 相似文献

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

This article analyses the history of Italian industrial districts (IDs) to identify lessons to help small and medium‐sized enterprise (SME) clusters in developing countries to move to higher stages of development. Transforming the 1990 seminal work of Brusco on distinct models of SME clustering into a stage approach, this article identifies a sequence of different maturity stages which the IDs passed through: initial craft production; industrialization through large firms; the fragmentation of production followed by the growth of smaller specialized units; and, finally, new routes to innovation and competitiveness. These phases help explain how development is a stage process which needs to be carefully considered and not rushed, through attempting to cross too many stages at once. Realistic steps are always necessary to create an effective base for growth. Furthermore, a theoretical framework is presented, which identifies three factorial levels that have intervened in the ID development process over the past 50 years. Economic, policy and social factors are identified and presented as drivers that work together to produce the structural changes that explain an effective development process. The final section emphasizes the relevance that this kind of analysis can have on the policy‐making schemes being applied in developing countries, with special reference to less developed types of clusters. 相似文献

Bear dentine aspartic acid racemization analysis: a proxy for the dating of Pleistocene cave infills
T. De Torres J. E. Ortiz F. J. Llamas L. Canoira R. Juli M. J. GarcíaMartínez 《Archaeometry》2002,44(3):417-426
A high correlation between chronometric determinations based on aspartic acid racemization ratios and radioactive dating methods is described from samples of cave bear (Ursus deningeri and Ursus spelaeus) dentine. For samples from a very restrictive environment, as deep cave bear sites are (in view of their highly stable geochemical and thermal history), an age calculation algorithm was obtained. It has been found that there is a very close relationship between collagen preservation, from total aspartic acid in the > 3500 D fraction, and the amino acid racemization. 相似文献
