A Ticking Clock? Preservation and Management of Greenland’s Archaeological Heritage in the Twenty-First Century

ABSTRACT

Evaluating the rate of deterioration at archaeological sites in the Arctic presents several challenges. In West Greenland, for example, increasing soil temperatures, perennial thaws, coastal erosion, storm surges, changing microbial communities, and pioneer plant species are observed as increasingly detrimental to the survival of organic archaeological deposits found scattered along the country’s littoral zones and extensive inner fjord systems. This article discusses recent efforts by the REMAINS of Greenland project for developing a standardised protocol that defines the archaeological state of preservation, the preservation conditions, and asset value of organic deposits. Special emphasis is given to the degradation of materials such as bone and wood that are historically observed to be well-preserved in Greenland but now currently at risk. The protocol provides a baseline for monitoring future changes and will assist archaeologists in Greenland with a procedure for documenting and predicting areas of increasing vulnerability due to a warming climate.     

阿尔寨石窟壁画颜料的拉曼光谱分析

本文利用拉曼光谱对内蒙古阿尔寨石窟壁画不同颜料进行了鉴定和分析。结果表明．绿色颜料为碱式氯化铜、蓝色颜料为蓝铜矿、白色为方解石、红色为朱砂、黑色为碳黑。这为阿尔寨石窟壁画进行研究及保护工作提供了科学的依据。同时也表明,拉曼光谱简便、快速、对样品要求量小．对样品无损分析,符合文物材质分析的要求,并可得到准确的信息。     

汉字民俗现象试析

汉字在其产生、发展、成熟和运用的过程中,也渗透出相当的民俗化现象,诸如自然祭拜、生殖崇拜、祈福禳灾、兼忌避讳、爱幼尊老,崇祀宗祖、敬惜字纸等习俗,在汉字本身就有明确的反映,从一个侧面体现了汉民族的心理发展历程。     

基于VRIO框架的饭店资源三维度评价模型

饭店是由各种资源构成的企业组织,饭店资源是与饭店竞争力密切相关的要素。论文在对饭店资源的内涵和结构进行分析的基础上,利用VRIO框架的4个基本问题,构建了饭店资源三维度评价模型。根据该模型,论文对饭店资源的价值性、稀有性和可模仿性分别提出了评价方法,并确定了饭店资源优化的条件。     

The first palaeontinid from the Late Jurassic of Australia (Hemiptera,Cicadomorpha, Palaeontinidae)

Chen, J., Beattie, R., Wang, B., Jiang, H., Zheng, Y. & Zhang, H., 12 April 2019. The first palaeontinid from the Late Jurassic of Australia (Hemiptera, Cicadomorpha, Palaeontinidae). Alcheringa 43, 449–454. ISSN 0311-5518.

Palaeontinidae, an extinct group of large arboreal insects, has the most diverse record among the Mesozoic Hemiptera, but only a few taxa have been reported from the Southern Hemisphere. Herein, Talbragarocossus jurassicus Chen, Beattie & Wang gen. et sp. nov., one of the earliest representatives of ‘late’ Palaeontinidae, is described and illustrated from the Upper Jurassic Talbragar Fossil Fish Bed in New South Wales, Australia. This new taxon constitutes the first representative of Palaeontinidae in Australia and the first Jurassic example in Gondwanaland, providing significant distributional and stratigraphic extensions to the family.

唐代崖州治所考

关于唐代崖州治所,《通典》等全国性史志皆明确记载在舍城县,正德《琼台志》等海南旧志则认为在颜城县。孰是孰非?因从来无人进行考证和评断,以至两说长期并存。现经深入考证,所得结论是“舍城说”所言为是,“颜城说”完全错误。至于唐崖州治故址,在今海口市琼山区府城东南三十里龙塘镇的珠崖岭上。     

北京延庆岔道城明代城墙灰浆失效因素研究

古代砖砌墙体多用灰浆作为黏结材料,其老化失效是墙体损毁的重要原因之一.本文应用红外热成像仪、X-射线荧光分析仪、X-射线衍射仪和离子色谱仪等,分析了北京市延庆地区明代岔道城遗址灰浆及其保存环境状况,通过模拟老化试验探讨了影响其长期保存的主要因素,为此类砖砌墙体保护与维修提供依据.
