The Lower Palaeolithic on the northern plateau of the Iberian Peninsula (Sierra de Atapuerca,Ambrona and La Maya I): a technological analysis of the cutting edge and weight of artefacts. Developing an hypothetical model

This article analyses the relationship between the weight and cutting edge of lithic artefacts from the main Lower Palaeolithic sites on the northern plateau (Meseta) of the Iberian Peninsula. The weight and cutting edge of a tool determine its cutting ability and the amount of force it is capable of, making them extremely important aspects of study to further our understanding of the potential capacity for human intervention in the environment. However, the analysis of these features has not received much attention in the ongoing debate on the Palaeolithic era in Europe. This study argues that the quantitative and qualitative technological analysis of these two aspects is of fundamental importance in determining the potential of lithic assemblages.     

The Use of Animal Hair in Ceramic Manufacturing at the Tytkesken-2 Neolithic Site,Western Siberia

The comb pottery found at Tytkesken-2 horizons 7, 6, 4A, and 4 reveals traces of animal hair. Hair was used as armature at the shaping stage: it was wound around the body of the vessel to prevent cracking during baking and drying (pastes were prepared without the use of hair). As the Tytkesken-2 ceramics demonstrate, using hair as armature was a local tradition, practiced in some measure from the Early to the Final Neolithic period.     

Analytical examination of animal remains from Borneo: the painting of bone and shell

Examination of a selection of shell and bone from archaeological assemblages excavated at Niah Cave and Gua Sireh, both of which are located in Sarawak, Borneo, has revealed the deliberate application of coloured material to one or more surfaces. Small fragments of the surface colourant were analysed using a variety of techniques, including microscopy, energy dispersive microwave analysis and infra-red spectrophotometry. These procedures established that, although red in colour, the applied coating in each instance was not red iron oxide. It is suggested that, based on the chemical components present, this coating was a tree resin or a similar organic substance. The paper further reports the presence of enhanced chloride values in the colourant recovered from the ancient human cranial fragment tested. It is suggested that elevated concentrations of this trace element may indicate that the site, the human remains or ingredients within the colourant were once in close proximity to the sea.     

Diversity in hunter–gatherer technological traditions: Mapping trajectories of cultural ‘descent with modification’ in northeast California

Recent work has demonstrated that technological traditions can be considered as systems of information transmission that operate on the principle of ‘descent with modification’. In this paper we present an ethno-historical case-study of northeast Californian hunter–fisher–gatherers. Our goal is to understand the factors generating long-term diversity in local material culture, and we begin by investigating the extent to which branching and reticulation explain variation in four distinct technological traditions – basketry, cradles, ceremonial dress and earth-lodges. We then examine whether these four traditions have been transmitted in tandem, or are characterized by entirely different descent histories. The results for this particular case-study suggest that the first three traditions have been closely associated during branching descent, while the earth-lodges appear to have entirely distinct transmission histories. The general analytical framework presented in this paper is readily exportable to other world regions, where local case-studies may generate contrasting insights into historically-contingent patterns of cultural inheritance. Further studies examining potential co-transmission of technological traditions are strongly encouraged as a welcome addition to the cultural transmission literature.     

A simple model of technological intensification

Ugan, Bright and Rogers [When is technology worth the trouble? Journal of Archaeological Science 30 (10) (2003) 1315–1329] develop procurement and processing versions of an optimization model, termed the tech investment model, to formalize the conditions that favor investing time in the manufacture of more productive but more costly technologies. Their approach captures the tradeoffs that occur as less costly versions are supplanted by more costly versions of the same category of technology (e.g., fishhooks), but not the tradeoffs that occur when more costly categories of technology supplant different but less costly categories used for the same purpose (e.g., hook and line vs. spear). We (i) propose an alternative model in which different categories of technology are characterized by separate cost–benefit curves, (ii) develop point-estimate and curve-estimate versions on this model, and (iii) show how they might be applied using the development of weaponry in aboriginal California as an example.

太仓半泾河古船可溶盐脱除技术研究

太仓半泾河古船发掘于近海河道,在保护修复工作开展前期,需采取脱盐处理。为全面了解船木含盐情况,针对不同部位不同树种的船体样品中的盐分种类与含量进行检测与分析。结果表明:船体样品所含以Cl~-和SO_4~(2-)为代表的可溶盐,采用超声波辅助加热去离子水浸泡法脱除,20 d可将Cl~-含量控制在1 mg/L,100 d可将SO_4~(2-)含量控制在1 mg/L。本研究结果可为后续保存工作提供有利条件。     

湖北郧县人遗址石器的第二步加工

郧县人遗址中发现的石器第二步加工的特点是大部分用石锤来直接进行加工;打击方向垂直或接近于垂直;修整痕迹多浅、平;加工方向大部分为单向加工,少数为交互加工、转向加工的;在两刃或两刃以上的石器中,不同边缘的加工方向相同的多,不同的少。郧县人遗址中的石器特征与国内外的旧石器时代早期石器进行对比,在石器的第二步加工技术方面,有着自己鲜明的特点,从而构成了独具特色的“郧县人文化”。     

The Origin of the use of the Tin‐Glazed Earthenware Technique in the Production of the French Medieval Pavement of Suscinio

The medieval pavement found in its original state and place at the Breton castle of Suscinio is an interesting case study for answering questions about the origin of the tin‐glazed earthenware technique in France. Twenty‐eight decorated tiles (with transparent and tin‐opacified glazes) and eight clayey raw materials were examined using chemical and microstructural approaches involving petrographic, SEM–EDS and XRD analyses. By combining the results of provenance and technological studies with historical and archaeological data, it was possible to conclude that the pavement was a local product, made with imported technological skills, rather than an imported product or the result of local experimentation.     

Occupational genders and gendered occupations: the case of water provisioning in Maputo,Mozambique

Taking issue with how associations between technical prowess or entrepreneurship and masculinity tend to be taken for granted or are seen as stemming from natural or intrinsic gender differences, over the last two decades feminist scholars have developed theoretical approaches to understand the gendering of professions and abilities as the performative outcome of particular cultures and histories. We build on these insights to explore how associations between masculinities, technology and entrepreneurship shape ideas and practices of small-scale water provision in Maputo. Our findings show how activities (i.e. technical craftsmanship, hard physical work) or abilities (i.e. risk-taking, innovativeness) regarded as masculine tend to be considered the defining features of the profession. This shapes how men and women make sense of and talk about their work, each of them tactically emphasizing and performing those aspects best fitting their gender. Our detailed documentation of men’s and women’s everyday involvements in water provisioning challenges the existence of sharp boundaries and distinctions between genders and professional responsibilities. It shows that water provisioning requires many other types of work and skills and male and female household members collaborate and share their work. The strong normative-cultural associations between gender and water provisioning lead to a distinct under-recognition of women’s importance as water providers. We conclude that strategies to effectively support small-scale water businesses while creating more space and power for women involved in the business require the explicit recognition and re-conceptualization of water provisioning as a household business.
