Building upon the work of scholars writing about Indian textiles and the textile trade of the western Indian Ocean, I examine a combined list of nearly eighty different specific types of Indian cotton cloths that were imported at Mozambique Island in the 1750s. In the absence of physical evidence, I seek first to identify each specific textile using archival and literary sources and then to categorise them according to provenance, design and price.  相似文献

Changing working conditions at many universities over the past decade have meant longer hours, intensified record-keeping, and more precarious employment. Despite these changes, many academics still insist that we enjoy our jobs. Our inquiry is oriented toward spaces and practices that bring us joy in our daily work and help us withstand the negative effects of working in academia. This article reports on our exploration of some moments of joy at work as part of our own academic practice. Through a feminist methodology known and developed as collective biography, we wrote individual memories of joy in our teaching, publishing, and collaborating, together at a writing retreat. As we analyzed these recalled moments, we came to realize that joy emerges through a turbulent process fueled by a cocktail of emotions. In fact, we came to understand joy as affect, with affect seen as a certain sort of excess, generated around and through sensations that might contribute to feelings such as celebration, happiness, or surprise as well as fear, anger, or embarrassment. We conclude that joy does things, that it can be transformative, and that cultivating joy in academia is part of a radical praxis.  相似文献

Survey of the coastal and inter-tidal zone at Kilwa in Tanzania resulted in the discovery of a series of artificial causeways and platforms at the entrance to the harbour of Kilwa Kisiwani, an important port trading with East Africa and southern Asia from around the 13th century. These appear to be part of a phase of monumental stone building at Kilwa in the 13th to 16th centuries, and represent a prosperous, confident Kilwa, impressing foreigners arriving by sea. Although necessarily speculative, several possible interpretations of their functions are advanced including navigation, protective breakwaters, access to marine resources, or ceremonial use.

Palynology, radiocarbon dating, and open-section stratigraphies from archaeological trenches are used to examine the impact of human activity around the time of Norse landnám on vegetation and landscape associated with a small farm (Ø34) in the Qorlortoq valley, Eastern Settlement, Greenland (61° N 45° W). Peat deposits from a mire abutting the Norse ruins revealed a discontinuous palaeoenvironmental record containing a possible hiatus from ca. AD 410–1020. Palaeovegetational data were recovered either side of this period. Pollen assemblages suggest that open Salix scrub dominated the landscape during the pre-settlement phase. The later phases of landnám resulted in the creation of hay fields and heavily-grazed grassy heath. Site abandonment is reflected by a re-expansion of Salix. This occurs shortly before the onset of deposition of a Sphagnum peat, dated to cal AD 1420–1630 (2σ) and reflecting an increase in mire surface wetness, probably in response to a deteriorating climate. Radiocarbon dates were obtained on peat and plant macrofossils sampled from either side of the proposed hiatus at two different but closely-spaced (<20 m) locations across the mire. These produced significantly different dates for the cessation of peat formation in the pre-landnám period (cal BC 2130–1770 and cal AD 240–410 respectively), but near-synchronous dates for the recommencement of peat growth (cal AD 890–1150 for peat and a probably more reliable interval of cal AD 1020–1190 based on plant macrofossils). It is suggested that this hiatus may represent the first direct evidence for peat cutting in Norse Greenland.  相似文献
