This study employs a brittle fracture-mechanics-based approach to explore the relationship between lithic fracture velocity and precursory loading rate in fine-grained lithic armatures. The data demonstrate that only high-speed dart and arrow armatures are subject to dynamic loading events, whereas spear and javelin armatures are limited to rapid (and quasi-static) loading. The data presented were derived from controlled experiments employing spears, javelins, spearthrower darts, and arrows. Armatures associated with both bow and spearthrower technologies are reliably identified and distinguished from those of low-speed technologies such as spears and javelins. Javelin armatures may also sustain higher velocity fractures than spear armatures, thus permitting the further differentiation of these technologies. The methodology offers a quantitative, non-subjective means to identify the delivery technology associated with a lithic armature. 相似文献

Archaeology is deeply troubled, but students are unlikely to learn about it in their ARCH 100 class. Our experience with ‘World Prehistory’ and ‘Introductory Archaeology’ courses and reviewing common textbooks charts a discipline securely anchored in the 19th century ideological harbour that is science, evolution, imperialism and progress. This includes so-called ‘middle road’ and ‘post-colonial’ approaches, which reinforce the status quo by limiting political action. In our search for an alternative, we discuss here our attempts to teach an anti-colonial archaeology rooted in critical pedagogy, political activism and anti-oppressive practice. At its core are three tenets: archaeology is personal, political and all about the present. While we are gratified by the many students who relish this opportunity for critical enquiry, we are faced with this lingering problem: most people do not want to hear the “negative reality” of archaeology. 相似文献

Velocity-dependant lithic fracture surface features are employed to determine precursory loading rate. The methodology is applied to a sample of Clovis channel-flake scars revealing that some Clovis points were fluted using pressure-flaking techniques. 相似文献

In recent years there has been increasing use of the term ‘empire’ to describe US primacy in world affairs. This should not be viewed merely as an indictment of US power: there are genuine insights to be gained from the study of imperial formations in contemporary politics. Yet there remains confusion and disagreement over the true meaning of ‘empire’. Progressive schools of thought in the academic discipline of international relations can facilitate a fresh understanding of ‘empire’—one that is suited to the complexities of the contemporary global scene. 相似文献

This article contributes to the significant debate on the effects of the Australian criminal justice system on Aborigines and in particular Aboriginal youth. This debate fed into nation-wide concern over an ever increasing number of Aboriginal deaths in custody, recently culminating in the Federal Royal Commission into Aboriginal Deaths in Custody. Through the use of case studies and other ethnographic data drawn from investigations in the country town of Port Augusta, South Australia, the author illustrates how the agents of the legal and welfare systems in this state operate to present a view of Aboriginal juvenile crime as a normal response to these children's social environment and social conditioning. This process in turn, it is argued, reinforces and legitimates Aboriginal juvenile crime and contributes to its continuance, and the subsequent over-representation of Aboriginal youths at all stages of the juvenile justice system. Yet it is forcefully pointed out that Aboriginal children are not passive victims of the legal and welfare systems. Rather, they form their own interpretations of these systems and their ‘criminal’ activities are often attempts at defiance and capturing some form of control of their own lives in the face of a legal/welfare system seeking to impose control over them. Unfortunately, it is these very activities which return Aboriginal children to the legal and welfare systems they act against. 相似文献

EXCAVATIONS in Wood Street, Nantwich uncovered two salt or wich houses, the first medieval wich houses belonging to an inland production centre to be thoroughly investigated. From the excavation a picture emerges of a highly structured and ordered organization, with each stage in the production of salt clearly defined and demarcated. The two wich houses were approximately the same size and both included amongst their equipment a trough, either clay-puddled or, in the later periods, a hollowed-out tree trunk, technically called a ‘ship’. These were used for storing the brine, once it had been carried across the river in wooden pipes. There was no trace of this aqueduct network. The brine was then boiled in lead pans over an open fire. There were six hearths to each wich house. The houses are dated to the late 12th century. One was pulled down shortly after it was built; for the other the last recorded date is in the 16th century. 相似文献
