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.     

Performance and Risks of Salt-Accumulating Renders in Relation to Their Moisture Transport Properties

Salt-accumulating renders are usually applied in several layers with different specific properties of moisture transport. An extensive experimental programme was carried out to establish a relationship between those properties of individual layers and the performance of combined systems on a salt-laden substrate. Each of the 20 renders was characterized separately in absorption and drying tests, vacuum saturation tests, dry cup tests, mercury intrusion porosimetry, and ultrasound wave velocity measurements. Each of the 12 combined render systems was applied on a brick, which was then saturated with a concentrated NaCl solution by free capillary uptake. Subsequently the assembly was closed at the bottom and subjected to an accelerated drying test (50° C and 15% relative humidity). Moisture and salt profiles over the depth were taken regularly during 1 month. The results reveal very different degrees of effectiveness and levels of risk for the substrate, which are related to the moisture transport properties.     

First Trials to Set Up a Microwave Reflectometric Tool for the Survey of Historic Timber Structures

Timber structures can be degraded during their life both by structural problems and by biological degradation factors like fungi and insects. The occurrence of those biodegradation agents could lead to a loss of their structural integrity, in the absence of appropriate maintenance. An early assessment of the decay is even more important when the wooden structures are part of historical buildings, in the interest of conservation of cultural heritage.

This article presents an application of microwave reflectometry for the in situ evaluation of timber structures. The measurement system allows detecting anomalies inside the material in a non-destructive and non-invasive manner.

The reflection coefficient is measured by means of a vector network analyzer (VNA) using a double-ridge antenna which transmits the continuous-wave (CW) microwave signal and receives the signal reflected by the material under investigation.

Measurements on laboratory models demonstrated the feasibility of the method. Results obtained on timber beam sections, compared with the findings of traditional investigation methodologies, demonstrate the potentiality of microwave reflectometry, suggesting its possible usefulness during the diagnostic phase as a non-invasive tool for preliminary screening.
