Central place foraging models are used to investigate assemblage variability at two Paleoarchaic (terminal Pleistocene/early Holocene) dacite quarries in the central and eastern Great Basin. Our analyses focus specifically on biface reduction and how varying degrees of reduction relate to the costs of transporting the resulting products upon departing the quarry. Our results suggest that when the distance to be traveled to a residential base is great, reduction will proceed further at the quarry than if the residential base is fairly close. Further, a residential site assemblage will consist of bifaces at later stages of reduction than its associated quarry. 相似文献

Concerns about the decline in uptake of secondary geography education continue despite arguments supporting the value of geography education, the power of geographical thinking, and geography’s critical role in preparing students to deal with complex challenges. Already constrained by neoliberal politics of disadvantage, young people must plan and prepare for chaotic futures. Consequently, young people are becoming distressed and worried about their futures and feeling powerless as society fails to adequately address these issues. In this article, we ask what schools and universities can do as place-based public institutions to serve young people to effectively respond to eco-anxiety and build capacities to surf the unrelenting waves of change. We draw on journeys that brought three young doctoral candidates to study geography. From their stories, we sketch what a geographical education could offer in terms of relevance, practicality, and engagement with transformative system change. We think that under current world conditions, this is a moment to revive geography education and give it renewed purpose to encourage young people to develop skills and competences to tackle wicked problems. 相似文献
The archaeological record of the Terminal Pleistocene and Early Holocene in the Great Basin consists largely of surface lithic artifacts, and consequently research has concentrated on typological and technological studies. The small suite of radiocarbon dates available suggests human presence in the Great Basin by at least 11,500 B.P., but evidence of subsistence is scanty. Technological analyses as well as artifact distributions suggest that the earliest occupants of this region subsisted primarily by hunting, possibly large terrestrial game. As elsewhere in North America, the earliest occupants of the Great Basin faced a rapidly changing environment, with the drying of shallow pluvial lake remnants and the creation of new habitats. Paralleling these changes, significant subsistence resource diversification coupled with expansion into new environments is evident by the close of the Pleistocene. 相似文献
Oratory, the act of speaking in public on civic matters, remained a male prerogative in the United States until the 1830s, when increasing numbers of women began ignoring the taboo and established a female oratorical tradition. This essay outlines how American women claimed the authority to speak and then developed their tradition, which was a social reform in itself, over three generations. It then examines how the youthful Jane Addams, a member of the third generation who became a social reformer, gained her education as an orator and struggled in new ways with society’s continuing doubts about women's civic authority. 相似文献
