Abstract

New methodological approaches focused on studying the reduction and use-life of stone tools have emerged in recent years, enabling researchers to move beyond strict technical and technological characterizations and explore specific aspects of occupation dynamics and economic management of resources. Previous studies have shown the importance of reduction distributions of individual measurements rather than averaged values. In this sense, survival analysis, and more specifically Weibull distributions, are one of the main inferential tools used in reduction studies. However, the resolution of Weibull distribution obtained from different methods has not been tested experimentally. In this paper, we present an evaluation of some of the main methods used in the study of core reduction intensity, such as the Volumetric Reconstruction Method, the Scar Density Index, and the non-cortical surface percentage. Our results show 1) strong and positive correlations between these approaches and actual reduction intensity, 2) similar Weibull distributions for non-cortical surface percentage, Volumetric Reconstruction Method, and logarithmic transformation of Scar Density Index. In addition, 3) the results from each method show a similar intra-assemblage variation, with a high percentage of agreement between them. As a result, all the evaluated proposals are useful and reliable methods for estimating the degree of reduction. Finally, a workflow is proposed for approaching reduction in archaeological assemblages by integrating different methods in the same study.
建立岩心还原强度及分布研究的新工作流程
近年来出现了新的方法方法,侧重于研究石器的减少和使用寿命,使研究人员能够超越严格的技术和技术特征,探索职业动态和资源经济管理的具体方面。先前的研究表明,单个测量值的减少分布比平均值更重要。从这个意义上讲,生存分析,更具体地说是威布尔分布,是约简研究中使用的主要推理工具之一。然而,不同方法得到的威布尔分布的分辨率还没有经过实验检验。在本文中,我们提出了一些主要的方法,用于核复位强度的研究,如体积重建法,疤痕密度指数和非皮质表面百分比的评价。我们的研究结果表明:1)这些方法与实际减少强度之间存在很强的正相关关系;2)非皮质表面百分比、体积重建方法和疤痕密度指数的对数变换的Weibull分布相似。此外,3)每种方法的结果显示出相似的组合内变异,它们之间的一致性很高。结果表明,所有的评价方案都是估计减少程度的有用和可靠的方法。最后,提出了一种通过整合同一研究中不同方法来接近考古组合减少的工作流程。
