Characterizations of palace lantern tassels preserved in The Palace Museum,Beijing, by UPLC-ESI-Q-TOF

Palace lanterns were important and highly visible decorations in the imperial palace in Beijing, China, during the Qing dynasty (1636–1912). Most lanterns had colourful tassels made of fibres. The study performed a comprehensive investigation of the materials and dyes used for palace lantern tassels preserved in The Palace Museum, Beijing. Eight samples with different colours, including yellow, green and red, from five palace lanterns were analysed. By using ultra-performance liquid chromatography combined with time-of-flight mass spectrometry, the compositions of the dyes were identified quickly, and thus the dyes' origins were explored. A X-ray fluorescence spectrometer assisted in the detection of whether a mordant was used during the dyeing process. As a result, the tassels were all made of silk, discovered through the use of microscopic observation and micro-Fourier transform infrared spectrometry analysis. Different dyeing techniques were found in these tassels: yellow tassels were dyed by cork tree or turmeric by a direct dyeing method; greens were dyed by pagoda bud with an iron mordant, or by the combination of cork tree and indigo using multi-dyeing method; and red tassels were coloured with different acid red industrial dyes. These results provide valuable data for the conservation of ancient textile tassels and contribute to the investigation of other hanging tags.     

《析津志·名宦》史源考——兼考元初中书官员刘肃的官职

元末熊梦祥所撰《析津志》(现仅存辑佚本)的"名宦"部分,从木华黎到刘因等47人的记载,是从《元朝名臣事略》中辑录而得,二者之间存在史源关系。确立了史源关系后,进一步梳理其中的内容,发现《析津志》和《元朝名臣事略》对元初中书官员刘肃的官职记载亦有误,应为"左三部尚书"而非"右三部尚书"。深入考察后进一步发现,《元史·百官志》对元初左右三部设置时间的记载亦有误,应为中统二年,而非中统元年。     

传统书画装裱修复技艺多元价值及其体系构建探究——基于"苏裱"传承人访谈的思考

价值多元化是中国传统书画装裱修复技艺重要的特征之一.当前书画装裱修复从业者对技艺价值认知程度不均,价值认知现状不能与多元价值共存的现实相匹配.基于非物质文化遗产保护与传承的视角,书画装裱修复从业者应从理念上重新树立多元价值观、方法上加强现代科技手段的有效介入、理念上重视传承人整体情况的深入探求、行动上加快技艺科学化研究进程等几个方面来全面构建技艺多元价值体系.     

内蒙古自治区社区干预在新冠肺炎防控中的作用机制及影响因素探讨

社区作为基层自治组织以其独特的职能和地位对重大公共卫生事件防控产生影响。本文构建社区干预机制体系,并基于内蒙古社区防控新冠肺炎的实证分析,探讨社区干预在地区和城市、农牧区间的差异,结合问卷得分情况并运用主成分分析法分别探讨影响地区间、城市和农牧区社区干预的主要因素。研究发现：内蒙古中部地区社区干预表现突出,东部其次,西部最差,城市社区干预显著优于农牧区;组织架构和职能发挥对地区内的社区干预效果影响较大。城市社区干预以组织架构和职能发挥为主,内外联系为辅,农牧区社区干预强调组织架构和内外联系,职能发挥薄弱;社区干预依照“组织架构响应--自身职能发挥--内外联系建立”的机制推进。     

Rediscovering regional science: Positioning the field's evolving location in science and society

This study aims to provide a comprehensive examination of the evolution of regional science, a scholarly domain in the social sciences that applies analytical and quantitative approaches and methods to understand and address urban, rural, or regional problems. We conducted a bibliometric analysis of 8509 articles published in six regional science flagship journals (including the Journal of Regional Science, Annals of Regional Science, Regional Science and Urban Economics, Papers in Regional Science, Regional Science Policy and Practice, and International Regional Science Review) from 1958 to 2021. The analysis presents an objective data-driven and unprecedented visualization of the field's intellectual, social, and conceptual structure and trends from the beginning to the present. It also provides a rich portrayal of the epistemology of regional science and illuminates matters related to regional science education and training. We find that regional science has moved well beyond its origins, shifting away from a heavy focus on theory and abstraction to modeling/simulation, empirical analysis, and policy research. We also find that there has been increasing attention to “people” in regions and the spatial characteristics of social problems, and some important shifts in the regional science community itself, particularly in terms of patterns of collaboration and the geography of scholarship. The findings of this paper provide implications for future directions of research and education for regional science.     

史前漆膜的分析鉴定技术研究

研究了漆膜分析的三种主要方法：裂解质谱,红外光谱,裂解色谱。通过大量实验比较了各种方法的适应性和可靠性,建立了以裂解色谱／富里叶红外光谱联用技术来鉴定漆膜,并对影响裂解反应的因素及色借条件进行了深入的研究,获得了可以重复,具有特征性的漆膜高分辨裂解色谱图,同时对裂解色谱图中主要组分作了定性鉴定,提高了裂解色谱法分析漆膜的可靠性。该方法具有灵敏度高,样品用量小,共存杂质影响小,操作简便等优点。应用核分析技术对河姆渡,良诸庙前遗址出土的二件红色涂料样品进行了鉴定。分析结果证实了河姆渡出土的红色涂料木碗上的涂料是我国至今发现的最早的生漆漆膜。     

明墓出土历书的揭取与复原

明墓出土的历书,粘连固结成块,脆硬易于折断。通过实验分析研究,探明其主要原因可能是木质素选择性地吸附的钙铁离子与蛋白质的分解物形成复杂物质,沉积在纸上,渗入书内所致。故揭取该历书的关键是去除钙离子,EDTA二钢,碱性过氧化氢、气相二氧化硅等的分步处理,使脆硬的纸张软化,再逐页分离揭取,然后再去除色素沉淀物,终于恢复了书的原貌。     

The Chemical Composition and Production Area of Early Western Zhou Proto‐Porcelain Unearthed from Yejiashan Cemetery,Suizhou, China

The bodies and glazes of 27 early Western Zhou proto‐porcelain samples from Yejiashan cemetery, Hubei Province, were analysed using LA‐ICP–AES, SEM, XRD, a thermal expansion instrument and other analytical methods. The results indicated that the bodies of all samples were characterized by high silicon and low aluminium, and were made with porcelain stone raw materials found in the south of China. The glazes are typical of high‐temperature calcium glazes of the CaO (MgO) – K₂O (Na₂O) – Al₂O₃ – SiO₂ series, with relatively high Mn and P content, which was probably caused by the addition of plant ashes. The physical properties and phase compositions of Yejiashan proto‐porcelain show that firing processes were still in the early stages of development in ancient China. Multivariate statistical analyses indicated that Yejiashan proto‐porcelain might have come from the Deqing area, in Zhejiang Province. These results provide new archaeological evidence for research on issues related to material flow in the Western Zhou dynasty.     

Revised conodont and fusuline biostratigraphy of the Bamchi Formation (Pyongan Supergroup) at the Bamchi section,Yeongwol and the Carboniferous–Permian boundary in South Korea

Wang, Q., Wang, Y., Qi, Y., Wang, X., Choh, S.J., Lee, D.C. & Lee, D.J., November 2017. Yeongwol and the Carboniferous–Permian boundary in South Korea. Alcheringa 42, 245–258. ISSN 0311-5518

Six conodont and one fusuline zones are recognized on basis of a total of 25 conodont and 13 fusuline species (including seven unidentified species or species given with cf. or aff. in total) from the Bamchi Formation, Yeongwol, Korea. The conodont zones include the Streptognathodus bellus, S. isolatus, S. cristellaris, S. sigmoidalis, S. fusus and S. barskovi zones in ascending order, which can be correlated with the conodont zones spanning the uppermost Gzhelian to Asselian Age of the Permian globally. The fusuline zone is named the Rugosofusulina complicata–Pseudoschwagerina paraborealis zone. The co-occurrence of the conodont Streptognathodus isolatus (the Global Boundary Stratotype Section and Point index for the base of Permian) and Pseudoschwagerina (a Permian inflated fusuline) indicates that the Carboniferous–Permian boundary can be placed in the lower part of the Bamchi Formation in South Korea.
