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

Stable carbon and nitrogen isotope analysis of 15 individuals buried closed to Bayanbulag site or the Shouxiangcheng fortress in southern Mongolia revealed complex dietary features. Only one individual had a diet similar to that of the pastoral population in northern China, while the others, who had varying carbon isotope values and low nitrogen values, might have been from different agricultural areas. ¹⁴C dating results suggest that the earliest interment could be much earlier than the building of Shouxiangcheng fortress recorded in Han texts. Analysis of the burial arrangement further confirmed that these deceased were not buried at the same time.  相似文献

Transit oriented development (TOD) advocates enhancing public transport connectivity, clustering urban development around public transport nodes and creating station areas with high-density, diverse land uses and pedestrian- and cycling-friendly environments. While this urban development approach is expected to have positive effects on the urban economy, the impacts of TOD strategies on economic efficiency are yet to be empirically examined. This study operationalised economic efficiency as labour productivity; developed a methodology to investigate how labour productivity is distributed at the local level, to explore the relationships between TOD characteristics and the clustering of labour productivities across different types of industries within a city; and applied it to the case of Beijing, China. The results show that in most cases the distribution of labour productivity has no significant association with TOD characteristics. However, in certain consumer-service-related economic sectors (i.e. wholesale and retail; accommodation and catering; and culture, sports, and entertainment) labour productivity is on average significantly higher in an area with stronger transit-oriented development characteristics. Furthermore, within the conceptual framework of agglomeration economies, the paper identified specific TOD characteristics that are related to the clustering of the higher level of labour productivities in certain industry sectors. These outcomes provide insights for developing more focused TOD strategies, aimed at enhancing the clustering of labour productivities in the identified industries around the existing metro station areas in Beijing.  相似文献

ABSTRACT

The George Reeves site (11S650) is a multicomponent village on the bluffs in the central American Bottom, Illinois. The site was occupied from the Late Woodland Rosewood phase through the Mississippian Lohmann phase. Pottery use and dietary variation between the Late Woodland and Emergent Mississippian occupations at the site were explored through stylistic analysis, pottery residue analysis, and compound-specific carbon isotopic analysis of pottery residues. Although more samples should be analyzed, diet and pottery use at George Reeves seems to have been varied, with maize present by cal AD 900–1000, but comprising a relatively small portion of lipid residues in pottery. Residue analysis indicates a C₄ presence in 5 of 16 sampled pots from the early Emergent Mississippian deriving from either maize or from meat from animals consuming maize. Pottery residues were mixed, showing C₃ and C₄ plants as well as meat and fish or shellfish. One residue showed a high incidence of C₄ contribution, most likely from Portulaca oleracea (common purslane), as well as large amounts of fish or shellfish and another C₃ plant. Residue from a ceramic pipestem indicates that maize may have been smoked, probably in the form of maize silk mixed with other nontobacco plants.  相似文献   

    

《Political Geography》2020

Disasters create spaces for the political to unfold. This paper contributes to the recurring debates on space and the political in geography by providing a novel empirical focus: following a fire in Lærdal, Norway in 2014, contesting discourses on how emergency services should be spatially organized revealed themselves. A scalar discourse of the local, situated in discourses on periphery and rurality in Norway, emerged to contest a neoliberal discourse promoted by the government. I illustrate the scalar discourse of the local through four identified narratives in Norwegian newspapers that emphasize different aspects of the local. This demonstrates how scalar categories are meshed with everyday vocabulary, and hence are important to study. Although a space of the political was realized following the fire, in the last part of the paper I reflect on why the scalar discourse of the local has not gained recognition as legitimate contestation, as reforms aiming to centralize and/or merge continue to be rolled out in Norway.  相似文献

ABSTRACT

Morphometric analysis offers an alternative or augmentation to traditional archaeobotanical methods to address differences within and between plant species and their remains, refining and enhancing taxonomic resolution. Morphometrics, the measurement of size and shape, and the multivariate statistical analysis of generated quantitative variables, have long played a major role in biological research, including plant taxonomy and systematics, although its application in archaeobotany is relatively recent. Over the last few decades, there has been an increasing interest in the use of morphometrics for analysing a varied range of archaeological plant materials (mainly seeds, pollen, phytoliths, and starch grains). In particular, morphometrics have contributed to the study of the domestication and spread of many cereals world-wide, as well as that of other taxa including legumes, underground storage organs (USO), and fruits (such as olives, grapes, and dates). This paper reviews current methodologies, recent applications, and advances in the use of morphometrics in archaeobotanical research, discusses its role in exploring major research questions, and suggests possible future directions for its use.  相似文献

ABSTRACT

In recent years, there has been a proliferation of sophisticated, user-friendly and accessible instruments of video data collection (e.g. mobile/cell phones and tablets) which facilitate video-based research and analysis. This paper reports on the opportunities and challenges of undertaking video analysis by reporting on the qualitative video analysis of a subset of 30 purposively selected videos from #notanurse_but, a parent-driven video campaign initiated by WellChild, a UK charity. This paper provides insight into one way of conducting video analysis, appreciating that a variety of approaches exist and that methodological reflections on analytical work with video recordings are limited. The authors critically consider researcher subjectivity; the everydayness of video data; making assumptions; and the incomplete picture provided by video data. Despite notable limitations to the approach of video analysis as a standalone method, the authors conclude that video analysis is capable of eliciting data that may not otherwise be obtained.  相似文献

ABSTRACT

A remote archipelago, Hawai'i, offers a plethora of sought after coastal and marine tourism experiences. The same unique marine fauna that draws tourists also makes Hawai'i a major player in the international ornamental aquarium trade. For many residents of Hawai'i, the marine realm is part of their island home and interactions with tourists and tourism activities are a part of everyday life. For many residents, the ocean is an important resource and for some a staple source of livelihood, be it through tourism, fisheries, or the aquarium trade. This variance between extractive and non-extractive marine resource use creates conflicts between stakeholder groups in Hawai'i. This study thematically analyzes public testimony records, which included 1652 individual testimonies, from proposed legislation aimed to establish ‘an aquatic life conservation program in the Division of Aquatic Resources to implement conservation measures, including limited entry areas and certification requirements, to regulate the collection of fish and other aquatic life for aquarium purposes. Public opinions evident in individual testimonies are representative of the disagreement in the literature regarding the stability and health of reef fishes populations in Hawai'i and broader resource-user conflicts. This study aims to better describe the user conflict between stakeholder groups in the marine resources of Hawai'i by exposing themes concerning change in natural environments.  相似文献

Fermentation is a common method of processing and preserving breadfruit throughout the Pacific Islands. While these pits are often reported in the archaeological record, they can pose some interpretive challenges. This paper presents an analysis of probable archaeological breadfruit (Artocarpus altilis (Parkinson) Fosberg) fermentation pits on Temwen Island, Pohnpei, Micronesia. Using the existing ethnographic record as a guide, I present archaeological and paleoethnobotanical criteria for identifying fermentation features. Architectural and stratigraphic analyses from four excavated pits match ethnographic expectations. Phytolith analysis shows some concurrence in terms of taxonomic data, but is more useful for indicating disturbance specific to building activities. Based on the distribution and size of pits present in the survey area, I suggest that breadfruit fermentation took place as primarily a household level (rather than community level) activity during the late prehistoric and early historic period in Pohnpei.  相似文献

We exploit a recent generalization of the Thrust Network Analysis (TNA) to analyse masonry structures of extremely complicated and audacious geometry such as helicoidal staircases. Actually, differently from available methods, based on ad-hoc solutions holding for each particular structure, the TNA allows for studying the equilibrium of structures of arbitrary shape by invoking the principles of limit analysis of masonry structures dictated by Heyman. Four paradigmatic monumental staircases, with increased degree of complexity, have been selected as case studies in order to show the versatility and accuracy of the proposed approach. The results entailed from the generalized TNA are also successfully compared, for the first time in the literature, with those related to the adoption of available analytical methods for the analysis of no-tension membranes.  相似文献
