Charcoal-tempered pottery is uncommon in North America, but was produced with notable frequency in Northeast Florida from ca. AD 300–600. Thirty-six thin sections of pottery were analyzed by petrographic analysis and compared to 10 clay samples in order to characterize the paste of charcoal-tempered wares in terms of charcoal and mineralogical composition and abundance, assess the number of clay sources used to make the pottery, identify the species of wood represented in charcoal inclusions, and infer techniques of ceramic production. This analysis identified four temper categories, three texture groups, and three distinct clay resources used to make charcoal-tempered pottery, all of which were likely local to Northeast Florida. Identified wood taxa include pine (Pinus sp.), cedar (cf. Juniperus sp.), cypress (cf. Taxodium sp.), and sassafras (Sassafras albidum), with pine suspected to be the most common. These genera of charred wood, which exhibit minimal shrinkage in the samples, along with the prevalence of bone and grog inclusions, indicate that hearth contents were processed as temper, sometimes in combination with quartz sand. Potential reasons for the use of hearth contents as temper are considered. 相似文献

The first step in a hysteretic energy-based design approach of performance-based design is the estimation of hysteretic energy demand in the structure. A nonlinear response-history analysis of the multi-degree of freedom model gives an accurate estimation, but it is not suitable for adopting in design. Two alternative methods, based on the concepts of modal pushover analysis (MPA) and 2D-MPA, are proposed in this article for uniaxial plan-asymmetric structures. Application studies show that both methods are efficient. While the 2D-MPA-based method is more accurate, the MPA-based method is more suitable for design adoption. Significant conclusions are given for prospective application of these methods. 相似文献

This article will critically examine theories of risk – referred to in this article as ‘pro-risk’ – as applied to parenting cultures in the UK through a case study of early years parenting, based in Walhamstow, East London. Common to all of these theories is an assertion that children are over-parented – a product of economic, social and cultural changes such as the decline of community as well as theories of child-centred parenting. Through the close examination of two examples where risk and community were contested, the article will argue that missing from these theories is an understanding of the embodiments of early years parenting, which underpin the way that parents handle the tensions between risk and development. Further, that parents sought to militate against isolation and the decline of community through local parenting networks. 相似文献

Abstract: Arguing that resistance to the state is too narrow a conceptualization of a political project that challenges neoliberalism, we posit that there are latent, residual apparatuses of the state which can be activated as part of a systematic progressive politics. We examine Massachusetts’“Dover amendment”, a legal framework which governs group home siting throughout the state. Dover offers a powerful tool with which to resist a neoliberal socio‐spatial agenda, though it has been underutilized toward enabling an alternative landscape. We analyze how and why Dover has often remained latent as a tool for socio‐spatial resistance, and consider a provocative case in Framingham, Massachusetts that suggests how residual state apparatuses may be leveraged in support of an explicitly resistive, progressive agenda. 相似文献

In order to allow for hydro development in Northern Quebec, it was necessary for the federal and provincial governments to negotiate conditions of settlement with the tree and Inuit people. These negotiations resulted in the James Bay and Northern Quebec Agreement in 1975. A process to define aboriginal rights was established when the Canadian Constitution was repatriated in 1981–1982. In 1983, the Constitution was amended to recognize, among other things, rights or free ‐doms acquired by way of land claims agreements, as well as existing aboriginal and treaty rights. However, after a series of constitutional meetings, participants did not agree on an amendment to entrench the right to self‐government. In the context of future development and actual practices, the exercise of rights is also extremely crucial; and, indeed, it is only through practice that those rights can be measured. 相似文献
