In the present paper, it is shown that in the Hergla area (eastern Tunisia), obsidian was present from the early to at least the late sixth millennium cal BC. The presence of cores indicates that obsidian knapping was at least partly carried out in situ. The origin of these obsidians was determined from their elemental composition, by comparison with those originating from western Mediterranean potential sources, including analyses of new samples from the nearby Pantelleria Island. All obsidians were measured following the same protocol, by particle induced X-ray emission or by scanning electron microscopy/energy dispersion spectrometry. All the Hergla obsidians were found to originate from the Balata dei Turchi sources of Pantelleria. A review of the present body of knowledge on eastern Maghreb suggests, in spite of the still very preliminary data available, that Pantelleria was almost its unique provider of obsidians from the Epipalaeolithic to and during the Neolithic. However, the relative importance of the two main Pantellerian sources of Balata dei Turchi and Lago di Venere as providers of obsidian to eastern Maghreb remains to be investigated. 相似文献

In this paper we evaluate the relative analytical capabilities of SEM-EDS, PIXE and EDXRF for characterizing archaeologically significant Anatolian obsidians on the basis of their elemental compositions. The study involves 54 geological samples from various sources, together with an archaeological case study involving 100 artifacts from Neolithic Çatalhöyük (central Anatolia). With each technique the artifacts formed two compositional groups that correlated with the East Göllü Da? and Nenezi Da? sources. The non-destructive capabilities of these methods are emphasized (albeit with certain analytical limitations in the case of SEM-EDS), suggesting important new techniques for Near Eastern obsidian provenance studies. 相似文献

Three projects on the theories of machines are presented: “mecanology” of the architect Jacques Laffite (1932) inspired by biological evolution; “mecanical analysis ” of Louis Couffignal, a specialist in computing machines (1938), which pre figures functional analysis, and the algebraic theory of machines by the mathematician Jacques Riguet (beginning of the 1950’s). During those years, the three men are members of the Circle of Cybernetic Studies. The article focuses on the dialogue between projects, the axes of unification and divergence, and the styles, strategies and postulates of these three candidates, for generalization converging toward the reference constituted by cybernetics. 相似文献

Many data sets collected for study areas consist of data values collected on a square lattice or for a set of pixels. Remotely sensed data provide perhaps the most common example. Frequently, we wish to know whether there are subregions of the study area that exhibit spatial clustering. In this article, we suggest how an approach for finding spatial clusters may be combined with the common practice of using 3‐by‐3 and 5‐by‐5 smoothing filters or kernels to construct two simple and easy‐to‐implement scan‐type tests. A simulation experiment shows that the power of these tests to find clusters compares favorably with an alternative test that is more complicated. The tests use simulated data, changes in a remotely sensed image for a study region in Texas, and data about wheat yields. Muchas bases de datos que se recopilan para una zona de estudio, consisten en valores recopilados en una retícula cuadrada o en un conjunto de pixeles. Los datos obtenidos por sensores remotos son quizá el ejemplo más común. Frecuentemente deseamos saber si existen subregiones de la zona de estudio que exhiban agrupamiento espacial. En este artículo, sugerimos cómo una aproximación para ubicar agrupamientos espaciales se puede combinar con la práctica común de usar filtros de suavizado (kernels) de 3‐por‐3 y 5‐por‐5 filtros, para construir dos test tipo scan, sencillos y fáciles de implementar. Un experimento de simulación demuestra que el poder de estas pruebas para ubicar agrupamientos, se compara favorablemente frente a otra prueba alternativa, que resulta más complicada. Las pruebas usan datos simulados, cambios en una imagen de satélite para un área de estudio en Texas, y con data acerca de los rendimientos de cultivos de trigo. 研究区收集的许多数据集是由基于方格网和像素采集的数据值组成的,遥感数据可能提供了最常见的范例。通常,我们希望了解研究区的子区域是否呈现空间集聚特征。本文提出了一种如何发现空间集聚的方法,可以与采用3*3和5*5平滑滤波或核函数的普通试验相结合,构造两个简单且易于操作的扫描试验。模拟实验结果显示,这些试验在寻找聚集特征的性能上优于更复杂的可替换性试验。文中所用的仿真模拟数据来源于德克萨斯州小麦产量的多时相遥感影像。 相似文献

Abstract In this article, the author studies the question how pastoral metaphors shape or construct the argumentative development and the internal structure of the Oracle against Babylon (Jer 50–51). Methodologically, the article draws on the insights provided by the cognitive linguistic approach to metaphor stating that metaphor is not merely a literary ornament, but rather a fundamental way in which people think. On the basis of these insights, the pastoral metaphors occurring in Jer 50,6–7; 8; 11–13; 17–18; 19–20; 44–45 and 51,38–40 are subjected to close scrutiny. It is shown that these metaphors display a strong internal development, challenging the view that the Oracle is an ongoing repetition of the same ideas. Moreover, the pastoral metaphors occur at structurally important positions in the Oracle, thus contributing to its overall architecture, and they provide important thematic links to other crucial texts in the book, e.g. Jer 25. Finally, the close analysis of the pastoral metaphors in Jer 50–51 has shed a new light on a number of the text's interpretational problems, for which new solutions were consequently proposed. 相似文献

Abstract Josephus, like the rabbis, had ambivalent feelings toward the prophet Elijah. On the one hand, because of the traditions identifying him with Phinehas the biblical zealot and portraying him as the forerunner of the Messiah (and therefore the leader of a revolt to bring about an independent Jewish state), Josephus, who was so indebted to the Roman imperial family, could hardly aggrandize him. On the other hand, because of Elijah's popularity as a folk‐hero with the Jewish masses Josephus could hardly afford to downgrade him, though he tones down the miracles associated with him. 相似文献
