The prisoners of the former concentrations camps were supposed to be deprived of their socialization by brutal dehumanization. Among other things, the use of blue-and-white striped prison clothes was meant to reinforce a homogeneous and uniform prisoner society. However, studies from a sociological perspective have shown that prisoners’ societies were indeed diverse and structured, allowing individuals to develop strategies of survival within their – albeit limited – scope for action. In this article, prisoners’ possibilities to act are discussed using the example of clothing – an omnipresent and visible medium. Various changes and alterations preserved in prisoner clothing from former concentration camps reveal open or secretive acts of individuals and thus provide insights into the different levels of action inside the camps. 相似文献

Biological invasions are one of the great threats to Earth’s ecosystems and biodiversity in the Anthropocene. However, species introductions and invasions extend deep into the human past, with the translocation of both wild and domestic species around the world. Here, we review the human translocation of wild plants and animals to the world’s islands. We focus on establishing criteria used to differentiate natural from human-assisted dispersals and the differences between non-native and invasive species. Our study demonstrates that, along with a suite of domesticates, ancient people transported numerous wild plants and animals to islands and helped shape ecosystems in ways that have important ramifications for modern conservation, restoration, and management. 相似文献

Which Bone to Pick: Creation,Curation, and Dissemination of Online 3D Digital Bioarchaeological Data
Brenna R. Hassett 《Archaeologies》2018,14(2):231-249
A fluorescence of shape-capture technologies at many different scales, including synchrotron, CT, micro/nano-CT, laser scanning, and photogrammetry, has led to a proliferation of digital data in bioarchaeology. The question remains how these new 3D datasets, alongside traditional bioarchaeological data, can be disseminated, and what ethical concerns are raised by trying to bring a sensitive topic into the ‘Open Access’ era. A survey of current resources and policies suggest the need for establishing best-practice standards. This paper outlines a sample of current resources, alongside modes of access and dissemination strategies to develop a picture of online Digital Bioarchaeological Data (DBD) use. 相似文献

This study heeds the call for a ‘truth-telling’ of injustices carried out on Aboriginal communities during the colonial acquisition of Australia as stated in the Uluru Statement from the Heart 2017. Here, we discuss the lives of eight Indigenous people buried in Normanton in north-west Queensland (QLD) who died and had their remains collected in the late 1890s as scientific specimens. The remains were later repatriated to the community before being further exposed by erosion in 2015. With the consent and participation of local traditional owners—the Gkuthaarn and Kukatj people—this assessment utilised bioarchaeological, historical and anthropological methodologies to gain a better understanding of Indigenous life and health on the Australian colonial frontier. Gkuthaarn and Kukatj people were engaged throughout the investigation, and statements throughout this piece made by them illustrate how bioarchaeology can inform on past injustices in Australia’s history, bringing them into the public consciousness and aiding the transition to reconciliation through ‘truth-telling’. 相似文献

Salt-accumulating renders are usually applied in several layers with different specific properties of moisture transport. An extensive experimental programme was carried out to establish a relationship between those properties of individual layers and the performance of combined systems on a salt-laden substrate. Each of the 20 renders was characterized separately in absorption and drying tests, vacuum saturation tests, dry cup tests, mercury intrusion porosimetry, and ultrasound wave velocity measurements. Each of the 12 combined render systems was applied on a brick, which was then saturated with a concentrated NaCl solution by free capillary uptake. Subsequently the assembly was closed at the bottom and subjected to an accelerated drying test (50° C and 15% relative humidity). Moisture and salt profiles over the depth were taken regularly during 1 month. The results reveal very different degrees of effectiveness and levels of risk for the substrate, which are related to the moisture transport properties. 相似文献

79 samples of black glazed pottery, Terra sigillata, fine common ware, and production indicators were recovered in the archaeological site of Cales and investigated via a multi-analytical program (polarized light microscopy, thermal analyses, XRPD, XRF, FESEM, FESEM-EDS). Among the materials, finds of important production indicators, represented by welded pieces of black glazed pottery and spacers, attest a local production. Polarized light microscopy shows that the inclusions consist of feldspar, quartz, mica, calcite, and lithic fragments of both volcanic and sedimentary nature. Additional information about the mineralogical assemblage comes from the XRPD that revealed the presence of neoformed Ca-silicates, indicating equivalent firing temperatures ranging from 750 to 1050°C. All the samples show a Ca-rich character and an extreme compositional homogeneity, including the production indicators. The comparison with some Ca-rich Campanian clay raw materials shows a greater affinity with the Mio-Pliocene marine clay sediments of the Apennine sector, which include local clays. This allowed us to formulate the first hypotheses about clay sources used to produce fine pottery during the third century BCE to the early imperial period in Cales. 相似文献

Nowadays, cities formulate long-term strategies to address the challenges and opportunities they face. Numerous strategic plans or planning instruments are developed for this purpose. In this article, we would like to examine the role, impact and relevance of these types of plans in decision-making processes concerning urban development projects (UDPs) in the Flemish Region of Belgium. To what extent do strategic plans succeed in capturing and steering the complexity of spatial interventions in contemporary urban contexts? We argue that a complexity-acknowledging perspective provides a more realistic and adequate view here by seeing strategic plans as only one among many elements in the set of tangled inter- and intrastrategic processes which together determine UDPs. A comparative and qualitative case study was carried out in the city of Kortrijk. The decision-making of three UDPs was studied thoroughly. Interviewing key actors and analysing policy documents helped us to (re)construct the complex decision-making processes and to stipulate the meaning of all involved formal plans and planning tools. 相似文献
