中国古代采矿工程技术史研究的几个问题

采用矿山考古、模拟实验等方法,对中国古代采矿技术的起源与发展进行系统论证后,得出三个论点：一是关于中国古代采矿工程技术的历史进程,可分为萌芽期(史前时期)、形成期(商代中期)、初步发展期(西周时期)、创新期(春秋至战国中期)、充实提高期(秦汉至元代)、全面发展期(明清时期)这六个发展阶段。二是中国古代采矿工程技术有着浓重的中国特色并具独特的发展体系,其多种技术的配合,在很大程度上基于中国古代各种社会要素的综合。三是中国古代采矿技术观是一种有机的、整体和综合的“和”的技术观,“和”明白地表述了采矿技术观的本质特征。

Non-invasive on-site method for thickness measurement of transparent ceramic glazes based on depth from focus

Glazed ceramics are a common material analyzed through geochemistry, whether in the form of tableware collected during excavations or tiles observed as part of architectural features. Within the framework of these studies, measuring the thickness of the transparent glaze is one of the useful variables available for the characterization of the ceramic, contributing to searches for provenance as well as serialization. However, this task often requires invasive methods performed in the laboratory, which may not always be possible. This paper develops a non-invasive and portable on-site system for measuring the thickness of ceramic glazes. Based on the depth from focus technique, this method makes use of a classical camera, a macroscopic lens, a translation stage, and a laptop for system control. In this article, we test this method through the measurement of glaze for ten samples as compared to results obtained for sections through scanning electron microscopy.     

The Abeng’s Call: The Articulation of Place and the International in Black Power Print Production

This article engages with radical Black Power print production in order to examine the articulation of Black practices of place-making and Black internationalist spatial politics. These spatial politics and practices are developed through engagement with the Jamaican Black Power newspaper Abeng which was produced at the height of Black Power activity on the island in 1969. The paper draws on Black Geographies scholarship to demonstrate that Abeng represented a material and discursive means through which subaltern practices and places of resistance in Jamaica were enacted in opposition to and excess of plantation spatialities and regimes on the island. The carving out of such subaltern places allowed for the articulation of transnational imaginaries and translocal solidarities with similarly aligned communities and struggles across the diasporic world. The Abeng newspaper was again central in crafting these imagined Black internationalist geographies and coeval praxes of transnational solidarity.
