Studying the process of enamel powder preparation for émail champlevé by colour measurements and μ‐X‐ray mappings

Colour measurements and non‐destructive μ‐X‐ray mappings have been used for the first time in a comprehensive study of medieval émail champlevé works from different production areas in France and Germany. This approach has given a new insight into the enamel powder preparation process of the glass material used for enamelling. Colour measurements demonstrated that all production centres used glass of very similar hues, but with large differences in colour saturation. The μ‐X‐ray mapping results of blue enamels are described by a semi‐qualitative approach. Significant variations in oxide contents of lead, cobalt, manganese and antimony oxides were found. The variations suggest that more than one glass material was used to prepare the powder for enamelling. The variations in antimony and cobalt show that glass had different degrees of opacity and colour depth. The manganese and lead contents, which do not correlate with the cobalt or antimony contents, indicate that probably glass of different base compositions was used to prepare the enamel powder for one champlevé field.     

NEW ANALYSIS OF CYLINDRICAL AND OVOID JARS (‘ARCHIVE JARS') FROM SOUTHERN JUDEA

This paper presents new compositional analysis of 26 fragments of the much‐debated cylindrical and ovoid jars, a vessel type first defined at Khirbet Qumran and associated with the Dead Sea Scrolls. The new samples include 15 examples from Tel ?evron, a site which yielded a pottery workshop and that carries certain similarities with Khirbet Qumran during the Early Roman period, as well as several examples from Jericho and Masada. According to the new as well as previous analyses, many of these jars were produced in the ?evron area; another source may be located in the northern Dead Sea area. The actual function of these jars, and whether they ever contained scrolls, is still unclear.     

La rivière Romaine en chantier : Transformations contemporaines des territorialités des Innus d'Ekuanitshit

Since 2009, Innu members of the community of Ekuanitshit have faced a major hydroelectric project on the Romaine River, an integral part of the Nitassinan, their ancestral territory. In this paper, we study the project's impacts on the material and ideational relationship the Innu have with the river. We explore the idea that the project transforms the traditional relationship to territory into a more pragmatic one, marked by economic and political interests. Our analysis reveals that the Innu's territorialities, though partly transformed by increased contact—and sometimes conflict—with hegemonic non‐indigenous society, remain anchored in a strong cultural heritage and a deep identification with territory. We argue that these seemingly differentiated conceptualizations, of traditions on the one hand and development on the other, are not incompatible. These conceptualizations comprise dynamic cultural, social, and political territorialities which are thus internal and external, ancestral and contemporary.     

‘M GLOW BLUE’: ARCHAEOMETRIC RESEARCH AT MICHIGAN'S FORD NUCLEAR REACTOR

The Ford Nuclear Reactor operated from 1957 to 2003 on the University of Michigan's North Campus in Ann Arbor, Michigan. Over its 45‐year lifespan, the facility played a key role in archaeometric research, fostering early methodological studies using INAA and supporting archaeological materials science investigations of lithics, ceramics, metals and bone. One small part of the FNR's abundant legacy was the initiation of trace‐element studies of Oaxacan ceramics, which are now beginning to shed light on early exchange interactions and the origin of the Monte Albán state in the Valley of Oaxaca, Mexico, between 500 bce and 200 ce .     

Wissenschaftsstädte – Zur Bedeutung des Topos der ‘kreativen Stadt’ für die Wissensproduktion

Science Cities: What the Concept of the Creative City Means for Knowledge Production. – The article aims to show that the relationship of science and the city has changed since the 1970s in the context of the knowledgeable society. While cities have principally been regarded as the typical space of science, of new ideas and innovation for centuries, since the 1960s and 1970s universities, research institutes as well as industrial research institutes have relocated to the periphery of cities. There, however, these sites of knowledge have been organized in an ‘urban mode’. That means that the concept of the city as a place of science and innovation has determined the architectural, spatial, and social organization of these sites on the periphery of cities. Certain features of the city have been copied, such as social infrastructures, places of communication, restaurants, cafes etc., while others have been left out – housing, cinema, theatre etc. An ‘urban mode of knowledge production’ in the sense of a very stylized model of the city has become a tool to enhance the production of scientific and technological knowledge. – The article exemplifies this by focusing on a case study, namely of the so‐called ‘Science City’ of the Siemens Company in Munich‐Neuperlach.     

肯尼迪政府调节国际收支逆差的政策

肯尼迪在美国面临巨额国际收支逆差的背景下入主白宫。严重的逆差导致美国的黄金大量外流,引起西方世界对美元信用的置疑。因此,调节逆差成为肯尼迪政府的重要使命。肯尼迪政府调节逆差的政策主要体现在肯尼迪提交给国会的两份特别咨文中,即1961年2月6日的“黄金和国际收支逆差特别咨文”和1963年7月18日的“国际收支特别咨文”。以两份咨文为蓝本,有关部门展开了系列的开源节流行动。美国的逆差调节行动使美国政府内部和北约盟国间的斗争起伏跌宕,充分暴露出权力政治的实质。     

"承负说"与两汉灾异论

作为《太平经》基础理论的"承负"说主要有两层含义:一是善恶报应,继承汉代之前中国本土的善恶报应思想;二是对汉代社会危机提出的一套解释系统,此与灾异论的盛行具有重要关联。前者为《太平经》对下层民众进行宗教教化准备了前提,后者为其政治改良方案的提出铺平了道路。尤其后者,对两汉之际不同派别的道教运动产生了革命性的影响,进而深刻影响了后汉之政治变迁。     

晚清圣母圣心会中蒙古教区传教述论

本文认为,晚清时期,圣母圣心会在中蒙古教区获得了持续、稳定的发展。教会的成功既在于其传教方法得当,也在于教会拥有较多的社会资源。怎样评价教会的传教活动,并不是一个容易的话题。     

建国初期党的"劳资两利"政策评析

基于对新中国建国方针的认识、对社会主要矛盾的判断和利用私营经济发展生产力的考虑,建国初期党和政府把“劳资两利”确定为处理私营企业劳资关系的基本政策。它包括保障私营企业工人的权益、保障资本家的正当权益、努力构建和谐的劳资关系三方面内容。这一政策体现了以毛泽东为核心的第一代中央领导集体勇于探索、开拓创新的伟大精神,极大地丰富和发展了马克思主义劳资关系理论,为构建当代中国非公有制企业和谐的劳资关系提供了有益的借鉴。     

Hunting,Herding, and Caravanning: Osteometric Identifications of Camelid Morphotypes at Khonkho Wankane,Bolivia

Khonkho Wankane is a ceremonial center located in the southern Lake Titicaca Basin, Bolivia. During the Late Formative period (AD 1–500), its residents practiced agropastoral lifeways and participated in the rise of the state at Tiwanaku. Like at many Andean sites, bones from the family Camelidae are the most abundant large mammal in domestic contexts. Identifying camelid morphotypes represented by these bones carries far‐reaching implications for understanding past hunting, herding, and caravanning practices, and their roles in larger social and economic webs. Identifications were based on a locally focused reference collection, including llamas (Lama glama) from the immediate vicinity of the site, as well as Andean guanacos (Lama guanicoe), a much smaller morphotype than the Patagonian guanacos used in many osteometric studies. Multivariate statistical analyses and incisor morphology identified all four camelid. Different analyses suggest that the crux of osteometry lies in the reference collection, not the statistical test. An additional, very large morphotype likely corresponds to a castrated llama, the preferred cargo animal among modern drovers. The presence of these animals is interpreted as evidence that groups hunted vicuña (Vicugna vicugna) and guanaco, which are not currently present around the site, herded llamas and alpacas (Vicugna pacos), and perhaps organized caravans with castrated llamas.
