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

Die Auswirkungen des Einsatzes
moderner Informationsund Kommunikationstechnologien (IuK) werden
oftmals unter dem Schlagwort der Globalisierung zusammengefaßt.
IuK-Technologien stellen die technischen Voraussetzungen
beispielsweise für die weitgehende Vernetzung von Unternehmen,
für neue Formen der Arbeitsteilung und
-kooperation.Im Fokus der wissenschaftlichen
Diskussion um E-Commerce stehen Veränderungen auf globaler
Ebene, die Frage nach den möglichen, raumwirksamen Veränderungen
in den Regionen wird dagegen nur wenig diskutiert. Was aber
bedeutet der Einsatz von E-Commerce konkret für Absatzmärkte,
Kunden- und Lieferantenbeziehungen auf der regionalen Ebene?
Besteht die Gefahr einer Schwächung insbesondere der
mittelständischen, meist regional verankerten Betriebe oder
bietet E-Commerce gerade für die kleineren und mittleren
Unternehmen (KMU) die Chance eines Innovationsschubs? Ein Blick
auf die regionale Ebene zeigt, daß hier zahlreiche
Förderaktivitäten unternommen werden. Dies wirft Fragen auf:
Welche Strategien sind bei dieser Förderung erkennbar? Wie geht
die traditionelle Wirtschaftsförderung mit diesem für sie neuen
Thema um?

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
