Primary questions regarding the foraging behaviour of the first hunter–gatherers who colonized the New World are how they found, procured and utilized high‐quality raw materials for manufacturing stone tools. In this paper, we present evidence from the late Pleistocene site of Cueva Bautista in the highlands of south‐western Bolivia, which demonstrates that a substantial portion of the recovered stone tool assemblage originated in Cerro Kaskio, a recently discovered obsidian source located 15 km south‐west of the site. In addition to describing the geological and geochronological setting, we provide the first geochemical characterization of the Cerro Kaskio source by means of instrumental neutron activation analysis and energy‐dispersive X‐ray fluorescence. Supported on the technological analysis and archaeometric sourcing of the obsidian lithics found in Cueva Bautista, we discuss the nature of the procurement strategies practised by the earliest mobile hunter–gatherers who explored and colonized the Andean highlands. We conclude that opportunistic lithic resource procurement was probably an important component of the first foraging societies that explored the highland Andes.  相似文献

This article considers the relation between infrastructural development and precarious work in the context of the electrification of a village in Northern Uganda. The case of a welder illustrates how partial electrification creates precarious conditions for work and how flexibility and creativity are used to mitigate its effects. In looking beyond precarity at the strategies employed by small-scale business owners in Northern Uganda, this article aims to shed light on how people relate to infrastructural realities and play an active role in shaping the affordances and impact of infrastructures in the Global South.  相似文献

Wholesale clearance and eviction that typify China's urban development have often resulted in discontents among urban residents, giving rise to what critics refer to as property rights activism. This paper is an attempt to critically revisit the existing debates on the property rights activism in China. The paper refers to the perspective of the “right to the city” to examine whose rights count in China's urban development contexts and proposes a cross‐class alliance that engages both migrants and local citizens. The alliance itself will have substantial political implications, overcoming the limited level of rights awareness that mainly rests on distributional justice in China. The discussions are supported by an analysis of empirical data from the author's field research in Guangzhou, which examines how local and non‐local (migrant) residents view nail‐households resisting demolition and forced eviction.  相似文献

Next to agriculture, road development is one of the most significant sources of stress to wetlands in Prairie Canada. However, there currently exists limited guidance for incorporating direct, indirect, and induced effects to wetlands in impact assessment and mitigation planning for small and often routine developments, including access roads or highway improvement initiatives. Based on the Louis Riel Trail, Highway 11 North twinning project in Saskatchewan, Canada, this article demonstrates a methodological approach and decision support framework for assessing and managing direct, indirect, and induced effects to wetlands from linear developments. No regulatory‐based environmental assessment was required for the highway project; effects were deemed to be insignificant under current wetland mitigation practices. However, our results show that 1115 ha of potentially affected wetlands are located within a 500 m impact zone on either side of the proposed highway. More than 50 percent of these wetlands are seasonal, less than 1 ha in size, and typically not included in mitigation planning. An expert‐based multi‐criteria evaluation of impact and mitigation options for wetlands in the study area indicated “no net loss” as a planning priority, and a preference for a spatially ambitious mitigation plan focused on direct, indirect, and potentially induced impacts. In practice, however, mitigation is often restrictive, focused on mitigating only direct impacts within the project's right‐of‐way, in this case less than 50 ha of wetlands, resulting in the potential for significant net loss of wetland habitat and function. If the risk to wetlands is to be given due consideration in project planning and development for roads and road improvement initiatives, then structured assessment methods and decision support frameworks should be sensitive to the time and resource constraints of small projects and screening‐type assessments. This requires also that wetland mitigation policies are developed and implementation plans formulated as part of project planning and assessment initiatives for linear developments.  相似文献

The present article argues that 1 Kgs 20-22 are not well-suited as historical sources for the Aramean wars, but are of considerable importance in the reconstruction of the world of ideas of that time. It is shown how animals and plants can be used as codes in the narrative. The use of lions, dogs and birds in 1 Kgs 20-22 illustrates one and the same theme: killing and devouring. Yahweh can appear as a lion or send a lion, but even though the lion kills, it does not “devour” the disobedient prophets of Yahweh. Yahweh is also behind the treatment of Ahab, Jezebel and the prophets of Baal, but Yahweh leaves it to dogs and birds to devour them. The king of animals is connected to Yahweh's prophets and the unclean animals to the apostate royal house. Through the codes we gain insight into certain basic modes of thought in Old Testament cosmo-ontology. For linguistic expressions acquire their meaning not only from the narrative sequence in which they are used, but also from the system in which they are included.  相似文献

Over the last 10 years, scholars in human geography have been paying increasing attention to the social construction of scale. Most of this literature takes its starting point in discourses of globalization and the way in which re-definition of scales operates through global political economics. This article is starting from an acknowledgement of the value of the scale debate for the analysis of urban everyday life and urban politics. Briefly, we reconsider the debate, in particular emphasizing the urban question as a scale question. However, we also identify some shortcomings in the debate so far. Even though many authors forward a conception of scales as relational, it is argued, they are often caught in a ‘hierarchical’ view of ‘scaling from above’. This is the background for an attempt to reverse the debate and consider the construction of urban spaces ‘from below’—from the practices and strategies of ‘ordinary’ people and organizations in the city. The interest in this article is how the diversity of everyday practices and politics interact with other scales in the construction of urban space.  相似文献

Total pore volume and pore size distribution are indicators of the degree of post‐mortem modification of bone. Direct measurements of pore size distribution in archaeological bones using mercury intrusion porosimetry (HgIP) and back scattered scanning electron microscopy (BSE‐SEM) reveal a common pattern in the changes seen in degraded bone as compared to modern samples. The estimates of pore size distribution from HgIP and direct measurement from the BSE‐SEM images show remarkable correspondence. The coupling of these two independent approaches has allowed the diagenetic porosity changes in human archaeological bone in the >0.01 µm range to be directly imaged, and their relationship to pre‐existing physiological pores to be explored. The increase in porosity in the archaeological bones is restricted to two discrete pore ranges. The smaller of these two ranges (0.007–0.1 µm) lies in the range of the collagen fibril (0.1 µm diameter) and is presumably formed by the loss of collagen, whereas the larger pore size distribution is evidence of direct microbial alteration of the bone. HgIP has great potential for the characterization of microbial and chemical alteration of bone. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献
