Egyptian Blue cakes from the Ayanis fortress (Eastern Anatolia,Turkey): micro-chemical and -structural investigations for the identification of manufacturing process and provenance

The microstructure and chemical composition of blue cakes, found during the archaeological excavation of the Ayanis fortress (Eastern Anatolia, Turkey), have been investigated by means of scanning electron microscopy combined with energy dispersive spectrometry (SEM–EDS), X-ray diffraction (XRD), micro-Raman (μ-Raman) and optical microscopy (OM) techniques. The analysis of the Ayanis cakes has shown the presence of Egyptian blue (i.e. CuCaOSi₄O₁₀, cuprorivaite), as the major component, intermixed with minor amount of other phases such as partially reacted quartz grains, an adherent glass phase and copper oxides. Since the finding of Egyptian Blue in Turkey has been never reported so far, great attention has been paid to its characterisation. The micro-chemical and micro-structural investigations of the Ayanis cakes have allowed a further insight into the manufacturing process and into the sources of the starting materials. The results of the characterisation have revealed some significant differences with respect to Egyptian blue cakes found in Egypt and Mesopotamia, as for instance the absence of tin excluded the use of bronze scraps or filings in their preparation differently from those produced in Egypt and Mesopotamia. Furthermore, some peculiarities of Egyptian blue found in Ayanis, as the detection of zinc in the cakes, allow to put forward the hypothesis of a local production considering that a large part of the bronze artefacts found at the Ayanis fortress is characterised by the presence of zinc as minor alloying element.     

旅行的意义:大众旅游者自我发展的视角

旅游已成为个体寻求自我发展的一种手段。本文以大众旅游者个体为研究对象,探索旅游对旅游者自我发展的影响及其作用机制。研究运用扎根理论研究方法,对所搜集的资料逐级编码、概念化和范畴化,发现大众旅游者自我认知的变化具有普遍性,构建了旅游者情境自我发展过程的框架,最终得到核心范畴——旅游者自我发展。研究发现,旅游者在旅游过程中或结束后对自我的内省能够促进自我发展;影响旅游者内省行为的两条路径分别是情绪过程和意志过程;情绪过程受到旅游者对旅游情境因素的知觉和出游动机的双重影响;意志过程主要受旅游者出游动机的影响。     

论邓小平的侨务思想和党的统一战线

邓小平的侨务思想是马列主义基本原理与当代中国实践与时代特征相结合的产物。他根据新时期的特点和国际形势的新变化 ,用新的思维和观点 ,继承、丰富和发展了毛泽东、周恩来所创建的中共统一战线理论。邓小平恢复和肯定“海外关系”的正确地位 ,作出海外侨胞是爱国的基本评价 ,强调要认真落实各项侨务政策 ,保护华侨华人的正当合法权益。为解决我国现代化建设中缺乏资金、人才和技术等问题 ,邓小平提出引进华侨华人和港澳台同胞的资金 ,引进华侨华人的人才与智力 ,吸引海外侨胞参与中国发展方略设计三大战略方针 ,并把统一祖国、振兴中华作为侨务工作的长期战略任务     

El policial palimpséstico en “Marta Odera,monja” de Marisa Grinstein

This article investigates the emergence of detective fiction and film from 1994 to the present. The corpus appears during the government of Carlos Menem and its intent to insert Argentina into a globalized economy. Poverty, insecurity, and violence prevail in Argentine society, and many detective novels, based on real-life murders, appear in 1994. Moreover, this type of literature continues to proliferate in the twenty-first century. In this essay, I explore one of the many stories written by Marisa Grinstein. I begin with the newspaper article and trace its transformation into short fiction and television series. The articles about the homicide follow the tendencies of the sensationalist yellow press. The author and the film director of “Marta Odera, monja,” however, transform the events, following and also subverting the characteristics of the classic detective fiction and the hard-boiled. In doing so, these recreations of this particular murder case denounce the domestic violence that exists in Argentine society.
