This study of livelihood patterns in a single rice village of coastal Guyana from 1887 to the present stresses economic and ecological linkages between the village and nearby sugar cane plantations. In the village of Bush Lot, typically populated by descendants of indentured plantation labourers from India, problems of maintaining drainage and irrigation canals have been compounded by a lack of village labour coordination. Varying yields from the community's ricefields have been affected by recurring drought and flood, so the villagers have never been full-time subsistence farmers. Rather, they have worked seasonally on the nearby plantations to supplement village farming activities. This part-time estate work has tended to inhibit social and political solidarity within Bush Lot. The plantations have coped better with water control than have villages. Nevertheless, the cane estates have depended upon nearby villages for seasonal labour. Although agricultural technology and scale of production have changed dramatically during the psst century, plantations and villages of the Guyanese coastal plain remain closely interlinked.  相似文献

The article explores the use of social robots as therapeutic agents for helping children with autism. I explore the circulation and use of mechanical analogies to describe autism, extended by psychiatrists and autism experts and adopted by robotic scientists interested in developing robots as social agents and in developing robots as therapeutic agents.  相似文献

Although archaeological evidence may express the results of several seasons of activity, the human skeleton, when correlated with archaeological and ethnographic data, provides information concerning daily activities performed throughout an individual's lifetime. Studies in occupational and sports medicine, along with electromyographic analysis of movement, have shown that different activities place different amounts of stress on human bone. In the present study, analysis of upper extremity musculoskeletal stress markers (MSM) has been used to clarify habitual activity patterns of two ancient Thule Eskimo groups from northwest Hudson Bay, Canada. Distinct pattern differences in muscle use occurred between Thule adult males and females and suggest possible gender-specific activity patterns that are not always discernible from the archaeological record alone. Temporal applications of the MSM data for Early and Late Period Thule support McCartney's theory of a substantial change in subsistence strategies through time, particularly among the adult males.  相似文献

The 19th‐century house of commons is traditionally viewed as a masculine space overlooking the presence of female tourists, waitresses, housekeepers, servants, spectators, and residents. This essay demonstrates that, even when formally excluded from the Commons, women were determined to colonize spaces to witness debates. In the pre‐1834 Commons they created their own observation gallery in an attic high above the chamber, peeping through a light fitting to listen to parliamentary sessions. After 1834, they were accommodated in their own galleries in the temporary and new house of commons, growing increasingly assertive and protective of their rights to attend debates and participate in parliamentary political culture. Far from being exclusively male, parliament was increasingly viewed through women's eyes.  相似文献
