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. 相似文献

Geographic research on neoliberalism has explored the restructuring of educational landscapes wrought through marketisation of preschool, school and higher-education provision and considered the responsibilisation of parents and children for educational outcomes. This study develops understanding of the contingent emergence of neoliberal educational reform, and its progressive and regressive impacts, through an examination of the burgeoning private tuition market in England and Wales. The paper outlines the contours of the previously hidden supplementary education industry, demonstrating that it reinforces regional and classed inequalities, while opening possibilities for ethnic minority advancement. Conceptually, the paper advances debate about socio-spatial specificity in neoliberal change, showing that the intersection of policy, free markets and consumer behaviour reshapes the educational landscape in ways that extend beyond state intention and control. Through these processes, contingent market forms are produced that offer social mobility for some, but ensure the social reproduction of enduring regimes of power. 相似文献

Summary. Recent archaeological work has thrown fresh light on the region of Moravia and SW Slovakia (ČSSR) at the time of the Roman Empire. It is now apparent that, as on other frontiers, Roman influence extended far beyond the Danubian Limes . This paper describes six sites with Roman-style masonry buildings; one of the sites, Mušov, has produced evidence of Roman military occupation and is associated with the Marcomannic Wars of Marcus Aurelius; the other five, however, are of civilian character with an interesting admixture of Roman and German structures and artefacts. These sites provide us with an insight into the relationship of the client kingdom of the Quadi with Rome. 相似文献

News wire services were established in the United States in the mid-nineteenth century to gather and distribute news for local newspapers, using the new technology of the telegraph. With that early beginning in the era of electronic communication, the expansion of news wire services spans the change from a society of local communities to a more nationally integrated society. This paper assesses the importanceof changes in the medium's spatial organization which promoted national culture. The first wire services were local, ad hoc groups, organized to achieve greater efficiency in news-gathering. Formal services were first organized on a local basis, but in 1848 they began to sell news to the major urbanized portions of the United States. As the nation grew, the desire for greater efficiency conflicted with the desire for greater autonomy. Regional wire services persisted from the 1860s to the 1880s but after the 1880s, a tenuous national organization was achieved, cementing itself into a national system after the turn of the century. Efficiency in news collection was the primary reason for the increasing scale of news collecting groups. Each step toward larger spatial coverage, fed the growth of a complex interdependent urban system. 相似文献
