Several archaeological finds of ancient boats in Britain are currently being reconstructed using a variety of methods and standards. This paper discusses some of the general principles that should be observed so that such endeavours will be scholarly valuable. The Dover boat case study (later in this issue) is based on the analysis presented here. © 2006 The Authors  相似文献

Avulsion fractures of the transverse processes of vertebrae have not been previously identified in the archaeological record. This paper provides a case study of a 21–25 year old male skeleton from the 10th century cemetery at Raunds Furnells (Northamptonshire, UK) with bilateral avulsion fractures of the transverse processes of the first thoracic vertebra. Possible aetiologies of this condition are discussed and conclusions drawn about the impact of this condition upon the individual. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

In the fall of 2001, staff of the Florida Bureau of Archaeological Research were led by river divers to an underwater site in the Apalachicola River containing a large concentration of prehistoric and historic artifacts lying on the riverbed. Subsequent inspection of the submerged river bank and scoured limestone river channel revealed a myriad of objects, which included iron fasteners, metal tools and implements, broken glass bottles, stone projectile points, scattered bricks and stone blocks, and other materials. Discovery of two large fragments of a wooden watercraft, a bayonet, a copper arrowhead, and flintlock gun barrels initially prompted researchers to hypothesize that the site might represent the remains of a U.S. Army boat that was attacked in 1817 by Seminole Indians while en route upriver. The episode, which caused the deaths of more than 30 soldiers and several women who were aboard the boat, led to the First Seminole War and the U.S. Army invasion of Florida. To investigate this hypothesis, a systematic survey of the riverbed was undertaken in the spring of 2002 to record underwater features and recover additional diagnostic artifacts. These activities employed side-scan sonar as well as diver visual investigations. This paper presents a case study of the value and broader significance of aggregate data where interpretation was underpinned by artefactual, historical and environmental analysis.  相似文献

试析尼克松政府对外政策决策机制、过程及主要人员   总被引:1,自引:0,他引:1  
现已出版的关于尼克松政府的著作,大多试图破译尼克松和基辛格这两位历史人物的思维方式以及他们的个性缺陷。根据新解密的尼克松总统档案和现已发表的英文研究成果,通过研究尼克松政府对外政策决策新机制的确立及其特点,透视尼克松政府对外政策决策机制、过程及涉及的主要人员相关特点,能够加强人们对尼克松政府对外政策决策的认识和理解。从理论上讲,尼克松政府的对外政策决策机制,目的是保证总统的工作日程和时间;总统得到的是经过认真研究、分析和过滤后的情报信息。尼克松任内,确实取得了外交方面的重大成功。然而,这一机制是将美国对外政策决策的千斤重担压到了尼克松和基辛格两人的肩上,违背了美国政府决策民主程序的理念。  相似文献

The NeoArabia project tries to understand how environmental, social, economic and technological factors work in concert to influence settlement and abandonment along a latitudinal transect of 1200 km from UAE to southern Oman. This region was affected by wide north–south variations in the Indo-Arabian monsoon, marine upwelling activity and eustatic variations in the Mid-Holocene. On the local settlement scale, this transect is based on fine stratigraphic excavations and permits the reconstruction of the site formation processes and site catchment analysis. A large number of studies have been conducted on the Ruways-1 site, focusing on a deep stratified sequence corresponding to three millennia of occupation. These studies include on-site climate-environmental signal analysis, local palaeogeography and environmental reconstruction, reservoir effect studies, typo-technological studies, palaeoeconomic strategies, anthropological studies, sclerochronological studies and, finally, site formation processes, the understanding of which makes it possible to explain the potential and limits of the archaeological excavation. The first results confirm the richness of these archaeological archives for documenting the socio-environmental dynamics, but also the richness of its complex sedimentary structure and the importance of conducting fine and multidisciplinary excavations to answer questions about the rhythms and functions of occupations and the causalities of socio-environmental changes.  相似文献

This paper elaborates on the types of knowledge sources, actors and geographical space that are involved in innovation processes among small entrepreneurial firms located in two distinct city-based clusters in Norway with firms characterized as typical STI mode innovators (Oslo Cancer Cluster) and DUI mode innovators (Subsea cluster in Bergen). The aim of the paper is to see how, when and why firms source distinct knowledge and to what degree this aligns with their initial knowledge base and STI or DUI innovation mode. Findings show that the knowledge base and innovation mode approach hold for describing the early stages of the innovation process, suggesting cumulative path-dependent knowledge dynamics. However, at later stages, firms combine STI and DUI mode innovation logics and activate different types of sources, actors and geographical scales through combinatorial knowledge dynamics, largely pushed forward by the need to solve unforeseen challenges, to understand markets and by the need to reduce risks associated with the newness of innovations. Furthermore, we find that rigid regulatory regimes influence the dynamic interplay between sources, actors and geographical scales in the process of creating and transmitting knowledge. Based on these findings, the paper proposes cluster roles and facilitation initiatives.  相似文献

This paper reports on an experiment designed to study the role of trampling in the vertical dispersal of artifacts in the soil, and in the mixing of originally separate sets of materials. The experiment is part of a study of the archaeological stratigraphy and patterns of site use at a large stratified cave in southern France. The experiment was designed to replicate conditions prevailing at the cave. The results strongly suggest caution in the interpretation of living floors and stratified assemblages in sandy deposits.  相似文献

Formation processes are all too infrequently addressed by archaeologists excavating in Mesoamerica. This paper examines refuse disposal patterns from the site of Cuauhtémoc on the Pacific coast of Chiapas, Mexico, to provide insight into how the site formed and how artifacts accumulated. This analysis uses materials dating between 1600–800 BCE which encompass the centuries before, during and after the late Early Formative or Early Olmec period (i.e., 1250–900 BCE). First, I employ sherds and daub from shared open-air middens and trash-filled pits to explore trash deposit formation through the 800 years that the site was occupied. Next, I use these same classes of data to make synchronic comparisons between five different depositional contexts dating to the Conchas phase (900–800 BCE). For all phases, these analyses demonstrate that pit features received more debris than open-air middens and that material in the latter contexts were more broken up. Further, the low density of daub from late Early Formative period contexts suggests that distinctive architectural customs may have been practised during this time. Conchas phase refuse indicates that waste disposal locations physically separated an elite residential zone from the rest of society and that elite contexts were more intensively used. Accounting for the formation of archaeological deposits allows for more nuanced interpretations of this early Mesoamerican village.

Thirty years after Muckelroy's seminal 1976 paper on shipwreck site formation, research on the cultural processes which contribute to the creation and modification of shipwrecks remains limited. It is proposed that by adopting a process-oriented framework, we can integrate and synthesize the documentary, oral and archaeological evidence of human response to shipwreck into a structure which parallels the physical progress of the disaster. Possible cultural responses to shipwreck are considered, from pre-voyage planning through to post-impact salvage, including physical correlations potentially visible in the archaeological record.

The German Continental Deep Drilling Program comprising a pilot borehole down to 4000 m and a main borehole down to 9101 m in southeast Germany (KTB) is continuing to provide a unique opportunity for the identification of important factors and processes in deep‐seated fluid and energy transfer. In situ stress conditions significantly impact flow, transport and exchange characteristics of fracture networks that dominate the permeability of crystalline reservoir rocks. In this paper, several scales of information are combined to present a fully three‐dimensional hydraulic finite element model of the principal KTB fault zones, and linked to a geomechanical model describing the alteration of the hydraulic parameters with stress changes caused by fluid extraction. The concept of geomechanical facies is introduced to define and characterize architectural elements in the subsurface system. Evaluation of a long‐term pump test in the KTB pilot hole, June 2002–July 2003, coupled with a geomechanical model gives an insight into some of the elastic and nonelastic processes controlling hydraulic transport in the basement rocks. Trends in the decline of the permeability and the degree of storage in the system could only partially be explained by elastic processes, clearly indicating the importance of nonelastic processes. A number of inelastic processes are suggested as areas for further research.  相似文献
