Soft‐stone vessels are a prominent feature of ancient culture throughout south‐east Arabia and the Gulf. Chlorite and steatite occur naturally in the al‐Hajar Mountains of the United Arab Emirates (UAE) and Oman; but until now, apart from the discovery of a few unfinished pieces, ancient production of soft‐stone vessels had yet to be documented in Arabia. This paper reports the discovery and preliminary analysis of soft‐stone vessel production at the site of Aqir al‐Shamoos. At this small and secluded mountain village, a range of soft‐stone vessels that are well known in the south‐east Arabian Iron Age were produced on a scale far beyond what was needed for local consumption.  相似文献

ABSTRACT This paper considers a two‐community model with free mobility, public expenditures set by majority voting, amenities that differ across communities, and two types of taxpayers sorting across communities according to different preferences. Residents pay local taxes, consume public services, and have the right to vote. Vacationers cannot vote, yet pay local taxes, and consume amenities. Amenities attract vacationers whose tax payments produce rents reducing the costs of public spending for permanent residents. These extractable rents produce stability in otherwise unstable equilibria. Relatively wealthy communities are generally less able than poor communities to extract rents.  相似文献

Artifacts of spherulitic rhyolite derived from two locations in northern New Hampshire are significant to minor components of numerous Paleoindian, Archaic and Woodland archaeological sites in Maine, New Hampshire, Massachusetts, Vermont and easternmost Quebec. The two known sources of are a dike near the city of Berlin, New Hampshire, and blocks-in-till near the village of Jefferson, New Hampshire. The source near Berlin has been a known source for “Indian relics” since the middle of the nineteenth century. The second source near Jefferson New Hampshire was first recognized in 1997. Both sources are situated along prominent east–west routes between the east flowing Androscoggin River on the east and the south flowing Connecticut River on the west. Mount Jasper is located above the Dead River. The Dead River flows east and enters the Androscoggin River approximately 3 km from Mount Jasper. Passage between the Connecticut and Androscoggin Rivers would have taken the travelers directly beneath Mount Jasper. To the west, from the upper reaches of the Dead River, the portage to Head Pond is approximately 0.9 to 1.5 km. From Head Pond access to the Connecticut is by way of the North Branch Upper Ammonoosuc River. The Jefferson source is located on terraces on the northwest side of the modern Israel River. The Israel River flows west and north for approximately 25 km into the Connecticut River. To the east the Israel River rises to a divide which separates it from the east flowing Moose River, which empties into the Androscoggin. Attribution to source is based upon comparison with known outcrops which include the combined characteristics of gross lithology, weathering characteristics, and bulk mineralogy. Comparison of dike samples with artifacts also indicate that the thickness and continuity of the flow bands together with spherule characteristics, which include, size, shape, volume, microscopic structures and weathering character, further suggest a limited source.  相似文献

A variety of agricultural conservation trends have gained and lost favour throughout the years, with farm bills in the United States often influencing which conservation practices are implemented. This paper explores the consequences of a set of conservation techniques loosely defined as “no-till agriculture,” focusing on their implementation and adoption since 1985, at which point such approaches began to be explicitly encouraged under US Farm Bill soil conservation mandates. We begin by noting a core contradiction that has characterized these approaches in the Fifteenmile Watershed of Wasco County, Oregon, where despite high rates of farmer enrollment in no-till programs, both no-till agriculture and sustained tillage have led to the increased use of herbicides and sustained sediment runoff. Using a critical physical geography framework that integrates intensive physical field data collection, spatial analysis, social surveys, and interviews, we address the biophysical and social factors collectively driving changes in herbicide use and variable erosion estimates. We draw particular attention to how farm bill support for no-till has enrolled farmers in a vaguely defined and underregulated conservation practice that may ultimately undermine environmental quality.  相似文献

Two stories are told simultaneously: one that may have been, and one that yet might be. The story of the voyage that might have been is based on archaeological evidence provided by the earliest shipwreck discovered in the New World. These two stories are set in different eras to demonstrate certain constants in the human drive to explore the unknown, in the methods used, and in the consequences encountered.  相似文献

Development organizations are increasingly adopting market‐based approaches to reducing rural poverty and food insecurity in the global South. The value chain approach is particularly popular. Aid donors, governments and non‐governmental organizations are applying value chain concepts originally designed for promoting industrial production to smallholder agricultural production. Cashew development in Côte d'Ivoire illustrates this new approach to rural development in which ‘upgrading’ the production and processing links are top priorities. A core assumption informing this approach is that improvements in product quality at the producer level will yield higher producer prices and incomes. This article examines this assumed quality–price relationship through a comparative analysis of cashew quality and prices in Côte d'Ivoire. The research reveals a disconnect between nut quality and producer prices. The case study demonstrates that power relations are more important than quality in setting producer prices for raw cashew nuts.  相似文献
