Models and classifications have been a part of thinking about public archaeology since at least the early 2000s, but how are these ideas translated into practice? By looking into the development of such classifications and models and by examining archaeologists’ attitudes to an archaeological education outreach project for schoolchildren in Oslo, Norway, this paper looks at the relationship between classification, theory, and practice in public archaeology. 相似文献

Histomorphometric semi-automatic image analysis of cross-sections of 101 femoral diaphyseal bone sections were performed to reconsider to what degree osteon remodelling in the outer cortex is affected by age. The data were analysed statistically using the generalized least squares method. The model estimation, which includes the covariance matrix of four single equation residuals, improves the accuracy of age determination. The standard deviation, however, of age prediction remains 12.58 years. An experimental split of the data was made in order to demonstrate that the use of subgroups gives a false impression of higher precision of age determination. The present study demonstrates that determination of age at death through microscopic bone morphometry is considerably less precise than generally stated in the literature. 相似文献

中国乡村社会空间的形成与演化 总被引:10,自引:0,他引:10
乡村社会空间反映了一定社会经济背景下乡村日常社会生活在地域空间上的分异与组合格局,其归根结底是由乡村社会主体的群体分化形成的。我国乡村发展历史悠久,改革开放以后变化尤其显著,研究其社会空间问题有一定现实意义。本文在对乡村社会空间的内涵进行阐释的基础上,分析了我国乡村社会空间的演变过程及现状特征,揭示了其形成演化的机制与规律,并对我国乡村社会空间的发展趋向进行了探讨。 相似文献

Instrumental neutron activation analysis (INAA) was applied to sherds from the important site of Huating and, for comparison, several Neolithic sites in the valley of the Yellow River. We hoped to compare the compositions of two stylistically different ceramics found at Huating, and to evaluate the degree of compositional clustering and inter‐site resolution that could be expected in an area that is noted for its extensive, and possibly very homogeneous, loess deposits. In addition, pottery sherds from Huating have been examined by microscopic petrography. All of these results will provide needed input in the planning of research towards the formation of a Neolithic/Shang Dynasty ceramic database for future use in archaeological research in China. 相似文献

Hydrothermal fluid flow models of stratiform ore genesis in the McArthur Basin, Northern Territory, Australia 总被引:1,自引:0,他引:1
This paper explores the role of basin‐scale fluid migration in stratiform Pb–Zn ore formation in the southern McArthur Basin, Australia. Mathematical models are presented for coupled brine migration and heat transport in the basin. The models account for: (i) topographically driven flow (forced convection) during periods when parts of the McArthur Basin were subaerial and elevated above the central Batten Fault Zone; (ii) density‐driven flow (free convection) during periods when the basin was mostly submarine; and (iii) transient flows associated with fault rupture during periods of transpression. These hydrologic models help to compare and contrast a variety of hypotheses concerning deep fluid migration and the origin of base metal ores in the McArthur Basin. The numerical results exhibit a strong structural control on fluid flow caused by the north‐trending fault systems that characterize the Batten Fault Zone. As a result, fluids descend to depths of a few kilometers along the western side, migrate laterally to the east through the clastic and volcanic aquifers of the upper Tawallah and lowest McArthur Groups, and then ascend along the eastern side of the fault zone. This recharge–discharge pattern dominates all of the hydrogeologic models. The basin‐wide flow pattern suggests that Na–Ca–Cl brines acquired base metals in the deepest levels of the basin stratigraphy as the fluids migrated eastwards through the aquifer system. Upward flow was relatively rapid along the Emu Fault Zone, so much so that fluid temperatures likely approached 130°C in the muddy sediments near the sea floor due to upward flow and venting at the HYC (‘Here’s Your Chance'). Transient pulses of flow characterized periods of transpressional stress and subsequent faulting may have punctuated the basin history. Large‐scale free convection, however, characterized notably long periods of diagenesis and ore mineralization during the Proterozoic in the McArthur Basin. 相似文献

南京城市扩展与其空间增长管理的研究 总被引:16,自引:1,他引:15
城市的空间扩展是城市化发展的直接体现,透过对城市扩展的分析研究,可以加深对城市化本质的理解,并可为城市可持续发展提供有效的空间决策资讯。本文选取南京城市扩展作为分析的具体案例,在充分认识和剖析自然景观、区域经济及城市用地结构特征等条件基础上,揭示了南京城市扩展的空间动态过程及其诱导性因子。基于对城市总体规划的概念性理解,论文概括了南京城市空间增长的基本管理措施:即,外围总体控制--框定主城区;主城内部空间的分片管理-结构优化;区域层面的都市发展区空间组织-外围空间引导。 相似文献

由于城市的复杂性、系统性和不可逆性,对城市问题的诊断与解决也必须运用系统化、模型化的方法。本文综述了1980年代以来,城市模型研究在基础理论、模型方法、技术和研究内容上新的发展。认为当代城市模型研究存在的突出问题是:仍然沿用工业化城市的经济社会规律,研究已经被信息化和全球化所深刻影响的城市;复杂性科学理论的综合性不够;GIS与其它模型的集成度有待提高。未来城市模型的研究应着重关注新的城市变化,综合运用复杂性科学的理论与方法,强化以GIS为平台的计算机技术。 相似文献

Previous evaluations of postprocessual archaeology have regarded it more as a critique of processual archaeology than as a viable research program. Today this statement needs to be modified to account for the diversity of frameworks that have grown up within and adjacent to the early postprocessual formulations. These new approaches include various admixtures of structural Marxism, poststructuralism, critical theory, and feminism. Significant philosophical differences separate some of these positions, but rather than being debilitating, the active exploration of these areas holds out new possibilities and prospects both for linking archaeology more securely to the other social sciences and for making unique contributions to the nature of social theory. 相似文献
