For many decades the use of backed pieces from the Howiesons Poort, between about 70 ka and 55 ka ago, in South Africa has been a point of discussion. Recently direct evidence has been provided to associate these tools with Middle Stone Age hunting strategies. Yet, whether they were used to tip hunting weapons or as barbs remained an open question. In this paper we introduce a set of pilot experiments designed to test the effectiveness of Howiesons Poort segments, the type fossils of the industry, hafted in four different configurations as tips for hunting weapons. It is shown that the morphological type can be used successfully in this way. We present the results of a macrofracture analysis conducted on the experimental tools and compare these to results obtained from three Howiesons Poort backed tool samples. By correlating experimental outcomes, macrofracture data and the interpretation of micro-residue distribution patterns, we provide some insight into the functional variables that might be associated with Howiesons Poort segments.  相似文献

We analyse the emergence of the ‘Highway to Heaven’, a distinctive landscape of more than 20 diverse religious buildings, in the suburban municipality of Richmond, outside Vancouver, to explore the intersections of immigration, planning, multiculturalism, religion and suburban space. In the context of wider contested planning disputes for new places of worship for immigrant communities, the creation of a designated ‘Assembly District’ in Richmond emerged as a creative response to multicultural planning. However, it is also a contradictory policy, co-opting religious communities to municipal requirements to safeguard agricultural land and prevent suburban sprawl, but with limited success. The unanticipated outcomes of a designated planning zone for religious buildings include production of an agglomeration of increasingly spectacular religious facilities that exceed municipal planning regulations. Such developments are accommodated through a celebratory narrative of municipal multiculturalism, but one that fails to engage with the communal narratives of the faith communities themselves and may exoticize or commodify religious identity.  相似文献

A mismatch between largely absolute Newtonian models of space in GIScience and the relational spaces of critical human geography has contributed to mutual disinterest between the fields. Critical GIS has offered an intellectual critique of GIScience without substantially altering how particular key geographical concepts are expressed in data structures. Although keystone ideas in GIScience such as Tobler's “First Law” and the modifiable areal unit problem speak to enduring concerns of human geography, they have drawn little interest from that field. Here, we suggest one way to reformulate the computational approach to the region for relational space, so that regions emerge not through proximity in an absolute space or similarities in intensive properties, but according to their similarities in relations. We show how this might operate theoretically and empirically, working through three illustrative examples. Our approach gestures toward reformulating key terms in GIScience like distance, proximity, networks, and spatial building blocks such as the polygon. Re‐engaging the challenges of representing geographical concepts computationally can yield new kinds of GIS and GIScience resonant with theoretical ideas in human geography, and also lead to critical human geographic practices less antagonistic to computation.  相似文献

Sites which have been occupied semi-continuously in the past present some inherent difficulties for archaeology. Here we present new research from a coastal site on the North Island of New Zealand at Cooks Beach where anthropogenic vegetation changes are seen using microfossil analysis of obsidian tools, sediments and pit fill. The results indicate the initial presence of people in AD 1300–1400 followed by subsequent periods of disuse or abandonment and sweet potato (Ipomoea batatas) cultivation. Around the time of initial settlement, obsidian from this location is found at sites across the country. After AD 1400 the area appears to be deserted for a century or more, after which we see evidence for the cultivation of sweet potato in AD 1500 as evidenced by extensive soil modification and numerous storage pits. There is no evidence of a permanent settlement at the site. The geographic distribution of Cooks Beach obsidian was constricted while the site was used for sweet potato cultivation, a pattern often attributed to increased warfare. It appears cultivation was abandoned after AD 1650 marking a second secession of use, a fact confirmed in AD 1769 when Captain Cook visited the area. We consider the possible drivers for the late abandonment of cultivation at Cooks Beach.  相似文献

For the British-Canadian writer and intellectual George Woodcock, the Doukhobors – a persecuted radical Christian sect, many members of which emigrated from Russia to Canada at the turn of the twentieth century – were a continual source of fascination. A cause célèbre for a host of nineteenth-century thinkers, including Leo Tolstoy and Peter Kropotkin, the Doukhobors were frequently portrayed as the exemplars of the viewer’s particular ideological beliefs. The present article examines Woodcock’s shifting interpretation of the Doukhobors, mapped onto the development of an intellectual career that saw him emerge as a leading anarchist thinker, and his broader transition from a British writer to a Canadian public intellectual. Where once he saw the Doukhobors representing anarchism in action, as his politics matured his view of the sect became more complex. Rather than living anarchists, he came to see the Doukhobors’ experience as a powerful reminder of the forces of assimilation at work in modern democracies that threatened the liberties of dissenters. Reflecting Woodcock’s revised anarchist politics, the Doukhobors’ story now became a key component of an intellectual vision that cast a probing light on Canadian history and Canadian cultural politics.  相似文献

Ports served not only as interfaces between land and sea, but as central gathering spaces for economic and cultural exchange. Drawing on case studies from the eastern Mediterranean island of Cyprus, this paper situates opportunistic ports lacking built facilities within a broader socioeconomic context of diverse maritime communications, expanding rural settlement, and increased agricultural productivity during late antiquity. Though simple, these sites served as active agents in the development of new maritime networks as well as local markets throughout their hinterlands, adding flexibility and dynamism to the economic ties between city, countryside, and the wider late Roman world.  相似文献
