Non-destructive PXRF analysis of museum-curated obsidian from the Near East

Non-destructive pXRF has the potential to expand sample populations of archaeological provenancing studies by facilitating access to museum collections of artefacts. In this study, we use museum-curated obsidian for the sites of Tell Brak, Mersin-Yümüktepe and Tell Arpachiyah and geological obsidian samples from central Turkey to demonstrate that non-destructive pXRF is comparable to other techniques in differentiating between Near Eastern obsidian sources. Secondly, we use multivariate analysis to evaluate whether non-destructive pXRF is sufficiently accurate and precise to enable comparison with legacy datasets from previous analysis using PIXE and ICP-MS. Multivariate analyses show that instrumental offsets between the results from pXRF and other analytic techniques are less than source-to-source variation typical for most Anatolian obsidian outcrops and pXRF-identified geochemical groups are directly comparable to legacy datasets. Non-destructive pXRF analysis indicates that during the Chalcolithic, East Göllü da? and Nenezi da? continued to be the major sources of obsidian to communities in central Anatolia and the Bingöl range and mountains surrounding Lake Van supplied sites east of the Levant. Variations in the analysed assemblages suggest a number of obsidian exchange networks existed during this period.     

Benchmark Standards for Geography: A personal review

The Human–Environment Research Observatory (HERO) Research Experience for Undergraduates (REU) program aimed to develop the next generation of researchers working on place-based human–environment problems. The program followed a cooperative learning model to foster an integrated approach to geographic research and to build collaborative research skills. The program hosted 12–16 students annually, who first engaged in an intensive short course and then formed three- or four-person teams to conduct research in four biophysically and socioeconomically diverse places. The teams used cyberinfrastructure to collaborate and integrate their research and findings. Most of the REU students have opted to attend graduate school and specialize in human–environment research.     

周代生态环境的考古分析

考古发现了大量的周代农业生产工具,这些生产工具反映了当时农业发展的状况及对生态环境的影响,而周代的古都城址不仅体现了当时的环境观,还能看到城市的发展对生态环境的改变,周代的厚葬风气文献记载和考古发现都很多,使我们看到当时厚葬之风的盛行及其与生态环境的关系。考古发现不仅弥补了周代文献资料缺乏的不足,还能使我们更加客观和直观地认识周代的生态环境。     

The student is not the fisherman: temporal displacement of young people's identities in Tanzania

This paper examines how young Tanzanians have their identities as environmental actors displaced into the future by local adults, teachers, educational institutions and teaching materials which seek to educate them about environmental sustainability and conservation. Whilst there has been considerable attention to young people's agency in reproducing their own identities, I argue here that the temporal displacement of young identities operates through a network of interlinked structures which act on young people's lives, including the identity work of young people themselves. Educational material produced by non-governmental organisations and the discursive work of adults both seek to position young people as having agency to act in and make decisions about the environment at an undetermined time in the future. Young people themselves can perform different identities within the space of the school and in the community or family, yet they may also understand their own identities as only having agency at a temporally distant point. The displacement of young identities has important implications for pedagogy which relates to environmental education, and for how the reproduction of young people's identities is conceptualised.     

Environment and Cultural Heritage in China: Introduction

The transformation of the natural and built environment over the past three decades has left China with a legacy of environmental degradation and loss of biodiversity. The loss of cultural heritage, including cultural forms associated with the natural ecology, has been just as dramatic. The three studies in this special focus section of Asian Studies Review explore significant issues in environmental conservation, cultural heritage, and grassroots activism in urban and rural China, with an emphasis on the relationship between the natural environment, the transmission of traditional cultural forms, and localised forms of agency or activism. As discussed here, while China's discourse on these issues is strongly influenced by global norms, different regions of China are developing their own individual responses to environmental conservation, the protection of biodiversity, and the ongoing transmission of endangered cultural forms.     

Insect species associations characterise past occupation sites

Assemblages of insects, mainly beetles (Coleoptera) from nine archaeological occupation sites in Northern England and one in Northern Ireland have been analysed statistically (principally using Spearman's rank-order correlation between pairs of species) in order to identify associations of taxa. Some sites gave strong and fairly discrete groupings, which could be related to individual insect habitats, or spatially or successionally related habitats, or to taphonomic pathways. Where less sharp groupings were identified, they included elements from those seen repeatedly elsewhere and appeared to reflect the character of the site, for example juxtaposition of habitats (as in stable manure), very uniform conditions, or rarity of insect habitats. It is concluded that, with suitable caution, analyses of this kind represent a transferable methodology of great value in obtaining archaeologically relevant information, as well as in improving our understanding of the way insects adapted to artificial habitats in the past.

博物馆融入多元人群的理论建构与现实实践

西方博物馆学研究在关注博物馆与"人"的问题时存在着一类倾向,即愈发强调人群的多元性.这种倾向以强调曾经被忽视或边缘化的人群以及人群内在的差别性为主要特点,同时,学界也惯于以"官方"与"非官方"这样的二元关系解释此类现象.对于中国而言,中国博物馆已有诸多收藏、展览、教育等实践均呈现出关照多元人群的一面,但从其关照的人群范...
