Secondary pit deposits in historical occupations of Near Eastern mounds are usually regarded as uninteresting and are seldom analyzed. We used an integrated approach to study all the artifacts as well as the sediments in a pit at Tel Dor, on Israel's Carmel coast, dating to the 7th c. BCE – a period when the site served as an Assyrian administrative center. This pit was unusually large, had a peculiar ceramic assemblage, and many macroscopic metallurgical wastes. A detailed excavation and analysis revealed that the pit served intermittently as a waste disposal site for an iron smithy and for pottery that was presumably involved in maritime trading. On two occasions the area was also used for animal penning. Despite the obvious importance of the iron industry to the Neo-Assyrian Empire, actual workshops are rare in its archaeological record. Hence the new information regarding an Iron Age iron smithy in the southern Levant contributes to the study of this industry, and also to the history of Dor in this period.  相似文献

Phytolith assemblages are analysed in an ethnographic agro-pastoral community in Northern Greece. A new method for analyzing the data, combined with the concentrations of phytoliths per gram sediment, helps to differentiate diverse uses of space in the village. The Phytolith Difference Index (PDI) contrasts the phytolith assemblages in sediment samples from the region around the village least affected by human activities with those in the village and its immediate surroundings. The PDI reveals that many of the samples are dominated by the input of the stalks of the domestic cereal, rye, which is used for food, animal fodder and roof thatching. The PDI also differentiates between dung from mules or donkeys with dung from free ranging cows and goats. Activity areas analysed include storage areas, stabling areas, animal enclosures, floors from living areas that were repeatedly swept, hearths and open areas between structures. The combined use of the PDI, together with phytolith concentrations and phytolith morphotype analyses, may prove to be useful for deciphering activity areas in archaeological sites of not only agro-pastoralists, but also pastoralists and hunter–gatherers.  相似文献

The phytolith record from archaeological strata is a powerful tool for reconstructing aspects of past human behaviour and ecology. Considerable insights into the problems and potentials of this record can be obtained by studying phytoliths in modern plants. We prepared a phytolith reference collection of modern plants mostly from northern Greece that includes quantitative information on phytolith concentrations (number of phytoliths per gram dry organic material) and morphological assemblages. Here we analyse this reference collection with the aim of evaluating the strengths and weaknesses of the archaeological phytolith record. The reference collection comprises 62 different plant taxa. Of them, 28 are trees, 1 conifer, 10 shrubs and 1 herb, 3 domesticated annual legumes and 19 monocotyledons. We demonstrate quantitatively the extent to which woody species, legumes and fruits of dicots contribute only small amounts of phytoliths to the sediments per unit tissue dry weight, while leaves of trees and shrubs produce significant amounts of phytoliths and grasses are prolific phytolith producers. We compare the data of this reference collection with a similar reference collection from another Mediterranean ecosystem (Israel). The comparison indicates that some aspects of phytolith production are probably genetically controlled, whereas others are environmentally controlled. We note that despite the fact that woody species produce few phytoliths per gram of tissue, their record can be most informative when taking into account other properties of the sediments. We also note that jigsaw puzzle-shaped phytoliths normally form in plants that grow in humid conditions, but may form in arid environments when the plants are irrigated. This study clearly shows the extent to which some plants can be under-represented and others over-represented in the phytolith record. Knowing the extent of this bias can greatly improve our interpretation of the phytolith record.  相似文献

聚落考古是当代考古学的基本方法之一,戈登·R.·威利就是这一方法的鼻祖。他自1950年代在秘鲁维鲁河谷的开拓性工作被公认为聚落考古的一座里程碑。之后,威利又做了大量这方面的研究,为这种方法的成熟和完善做出了巨大的贡献。其中,玛雅低地的聚落形态研究就是威利的经典案例之一。在这篇文章中威利主要探讨了通过玛雅低地聚落形态研究其政治、经济问题的一些方法与途径,并结合玛雅象形文字资料,得出了对古代玛雅社会一些迥然不同于以往的新认识,并由此深刻反思了聚落考古方法的优势和局限性。本文的研究方法以及所提出的一些问题对于今天方兴未艾的中国聚落考古研究有着深刻的启示:聚落考古对于文明起源与农业起源这些战略性课题的研究有何重大意义?如何全面看待聚落考古方法本身?如何使调查资料与其它资料结合?,这些都是非常值得我们重视、思考和借鉴的问题。  相似文献

We investigate the “determinants” of spatial variations in youth unemployment and NEET rates, and the presence of spatial clusters, for Italy, Spain and the UK. We aggregate Labour Force Survey data for the period 1993–2018 to a “regional” level. We find that youths are sensitive to aggregate labor market conditions and a discouraged worker effect. In the UK and Spain, temporary jobs are more likely to be preferred to part-time jobs, whereas in Italy the opposite occurs. There is evidence of spatial clustering of youth unemployment and NEET rates. We discuss the implications for place-based regional and labor market policies.  相似文献

2009 is the thirtieth anniversary of the Iranian Revolution. In 2006 the Bush administration ranked Iran as posing arguably the greatest single threat to America. And throughout 2008 that administration insisted all options were open in dealing with Iran, including preventative strikes. Yet, unlike its decisive intervention to establish Iran as a client state in the 1950s, the US has thus far been unable to force the changes it desires in and from Iran's leadership. This article argues that to help understand this situation it is important to recognize that the Iranian Revolution was and remains nurtured by a contemporaneous “silent revolution” in the international oil industry, even if the Ahmadinejad regime's economic policies especially threaten currently to squander some of the potential afforded by it.  相似文献
