Methodological aspects of SANS and TOF neutron diffraction measurements on pottery: the case of Miseno and Cuma

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.     

辽金人的忠孝观

忠孝是中国古代伦理的重要内容 ,中国传统文化的组成部分。契丹、女真早期本无忠孝观念。辽金建立后 ,随着社会的发展 ,儒学的传播 ,统治者的倡导 ,民族的融合等 ,忠孝观念逐渐形成和发展起来。忠孝在辽金及后来元人那里 ,超越了民族、地区和国别的畛域 ,人们对外族、邻国、敌国乃至前朝的忠臣孝子同样表现出尊重和崇敬。 1 0 - 1 3世纪 ,忠孝已成为汉、契丹、女真、蒙古等各民族一致认同的伦理道德观念和行为规范 ,从而体现了中国传统文化的历史继承性和强大凝聚力。     

"吧国公堂"档案之《公案簿》述略

<公案簿>是现存吧国公堂(巴达维亚华人评议会)档案中的核心部分,所涵盖的时间范围大约为150年(1787-1940年)左右.<公案簿>的内容主要有两个方面一是对吧国公堂有关华人的各类案件的会审记录;二是对有关吧城华人社区重要事件和重大决议的记录.对涵盖这一时期最为原始的记事录的内容及案例加以考察和分析,一方面可以洞察一个处在多种变革时期具有代表性的华人社区的社会生活及其行政管理的内幕,另一方面也可以从中了解各个历史阶段荷印殖民政策的变化及其对当地华人社会的影响.     

Bear dentine aspartic acid racemization analysis: a proxy for the dating of Pleistocene cave infills

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.     

The Material Characterization of a Santamarian Ceremonial Axe

The characterization of a ceremonial bronze axe is described. The axe is assigned to the Santamarian culture of north‐west Argentina, c. 1000–1470 ad, and was selected to increase presently limited knowledge of prehistoric metallurgy in the Andean region of Argentina. The characterization methods used were electron probe microanalysis, gamma radiography, X‐ray diffraction, optical metallography and microhardness testing. The axe was well cast in a bivalve mould, with the only defects in the area of an ancient fracture. The analysis showed that it is made from a tin bronze with a, probably, accidental addition of lead. Arsenic was found as a surface contamination, probably deriving from arsenic in the water of the stream in which the axe was found. The axe shows that Santamarian craftsmen had the skill to decorate the axe in an artistic style with a strong local accent while providing a functional, annealed and cold‐worked cutting edge.     

Law as an anti‐value: Justice,violence and suffering in the logic of becoming (Respond to this article at http://www.therai.org.uk/at/debate)

Anthropologists are chronologically only the latest to have adopted justice (and injustice) as an object of (critical) inquiry. Even among anthropologists, however, the radical critical cry that law is the instrument par excellence of control and repression, has today fallen out of fashion. Starting from the Afghan case, in this paper I reflect on law as a potential source of violence and as an anti‐value – in the sense of being in antithesis with accepted social values – in the contemporary global scenario. My focus here is neither on the uses that can be made of law nor on the outcomes of its interpretation and application. Rather, I am interested in what law can generate when it betrays social values and sentiments of justice.     

Towards a three-dimensional cost-effective registration of the archaeological heritage

Archaeological practice within the European context of heritage management is facing huge challenges in ways of recording and reproduction of ex-situ preserved sites. As a consequence of the Valletta-treaty, numbers of archived images and drawings of excavated structures as prime sources of past human activity, are exponentially growing. Contrarily to portable remains however, their future study and revision is biased by the two-dimensional character of the recorded data, rendering difficult their future reconstruction for new study or public dissemination. A more realistic three-dimensional (3D) way of recording and archiving should be pursued. In this paper the possibilities for 3D registration of archaeological features are examined in a computer vision-based approach using the PhotoScan software package (Agisoft LCC). It proved to be a scientific and cost-effective improvement compared to traditional documentation methods. Advantages can be found in the high accuracy and straightforwardness of the methodology. The extraction of an orthophoto or a Digital Terrain Model from the 3D model makes it feasible to integrate detailed and accurate information into the digital archaeological excavation plan. The visual character of 3D surface modeling offers enhanced output-possibilities allowing a better documentation of in-situ structures for future research and a higher public participation and awareness for the archaeological heritage.
