Gestures of judgement and welcome in public spaces: hypervisible migrant newcomers in Darwin,Australia

This paper draws on ethnographic research to show how pigmentation intensities of skin and facial characteristics make bodies of colour recognisable in public spaces of Darwin, a small multiethnic and multiracial north Australian city. This paper shows that the visibility of newcomers, in particular, humanitarian migrants from countries in Africa, the Middle East and Asia, circulates negative sentiments of fear, anxiety and discomfort in public spaces when instantaneous judgements are made. These judgements of misrecognition made by residents of diverse ethnic and racial backgrounds lead to simmering tensions that unfold as visceral events of vulnerability in public spaces such as bus interchanges, neighbourhood streets, shopping centres and car parks. These events that have the potential to wound and numb bodies contribute to the “urban unconscious” of Darwin as a city where public spaces are safe with heightened surveillance. This paper argues, however, that events of hypervisibility, judgement and interracial tensions can unfold quite differently in public spaces if humanitarian migrants sense gestures of welcome, particularly from Aboriginals. Such fleeting moments of welcome in Darwin have the potential to bring together bodies with different histories and geographies of racialisation, so that multiple publics emerge through everyday habits of living with difference.     

THE TIBETAN VILLAGE OF NORTH WEST YUNNAN-a basic grammar of local authenticity

This work is the result of a journey in North West Yunnan. The European architects try to identify and explain which the main characters of local authentic architecture are, and to define a basic grammar. Observing the ongoing trends of change, they make comments and give some basic personal suggestions about architectural conservation. Authenticity is not an absolute idea and it should be clear that the following observations come from a European conservationist point of view. The document is written in the perspective of promoting a conservation oriented to tourism development in the area.     

The spectacle of the poor. Or: ‘Wow!! Awesome. Nice to know that people care!’

On the night of 14 November 2012, a police officer of the New York Police Department encountered a homeless person while performing his duties around Times Square. He gave him a pair of boots and while doing so, he was photographed by a tourist. The photo was posted on Facebook, receiving in a few days more than 1.6 million visits. The paper unfolds the reasons why this particular image and story have gone, as the media has put it, ‘viral’. The paper investigates the spaces that have emerged in the media elongation of DePrimo's practice of care and, introducing the notion of ‘spectacle of the poor’, it argues that this specific case simplifies the dominant western framings around matter of ‘caring for the poor’. The political and cultural consequences of these framings are investigated, and reflections on how to tackle them provided.     

Rights,participatory spaces and the daily fabric of children and young people’s voices in Switzerland

ABSTRACT

The past two decades have witnessed an unprecedented rise in public policies aimed at hearing children and young people’s voices, which typically entail creating supportive participatory spaces. While this political project is usually presented as a radical move towards a more inclusive society, it raises critical questions about whose voices are being represented, how, why, by whom and for whom. Drawing upon recent ethnographic research on childhood and youth policies in Switzerland, this article explores how children and young people’s voices are produced in concrete situations. It studies how the institutional and material characteristics of participatory spaces and situated interactions shape which voices will actually be heard. The research highlights that, despite their inclusive ambitions, participatory spaces paradoxically exclude young persons who fail to articulate, orally or in written, linguistically, morally or politically legitimate voices.     

Vitrification of basalt orthostats and mud building components from Tilmen Höyük (south-eastern Turkey): an experimental and geoarchaeological approach

Finds of basalt orthostats and mud building components from the archaeological site of Tilmen Höyük (south-eastern Turkey, early 2nd Millenium BC) preserve a glassy crust formed by vitrification of the material. It is proposed that such features are related to destructive fire events, which destroyed the wooden building elements and burned natural stones. The geoarchaeological and experimental approach confirms this hypothesis. The geochemical composition of experimental melts is comparable to that of natural basalts. Spot analyses evidence the heterogeneity of the melts, especially for mudbricks and ceiling plasters. It is concluded that the investigated finds were subjected to strong burning under oxidising conditions reached during a violent fire. Temperatures similar to those derived by experimental melting (1180–1195 °C) were likely reached in the fire at Tilmen in order to produce the glass observed.     

Investigating a child sacrifice event from the Inca heartland

Human sacrifice in the Inca Empire at times took the form of the capacocha, a sacrificial rite involving the most beautiful children in the empire. In this study, we investigate a possible capacocha at the pre-Columbian site of Choquepukio in the Cuzco Valley of Peru. During excavations at Choquepukio in 2004, seven children (aged 3–12 years) were discovered buried together; accompanying them was an elaborate assemblage of high status artifacts similar to those from other recent archaeological finds that are believed to be capacocha sacrifices. Since colonial documents indicate that capacocha children were selected from diverse regions of the empire, we initiated a radiogenic strontium isotope analysis to determine the origins of the children found at Choquepukio. Our analysis showed that, indeed, two children in the assemblage had non-local origins. When considered together, the osteological, archaeological, and isotopic evidence suggest that a capacocha event occurred at Choquepukio, representing the only lower-elevation capacocha to have been found in the Cuzco region.     

Sonic Tomography for Masonry Walls Characterization

ABSTRACT

Nowadays, Sonic Pulse Velocity tests (SPV tests) are widely applied for detecting the morphology, hidden defects, and voids within structural elements. This technique, largely applied because non invasive and easy to perform, reveals particularly adapt in the case of ancient buildings, where usually any damage is not tolerated due to the historical preservation requirements. Moreover, recently the SPV tests have been also applied with tomography technology to obtain images of sonic speeds from which it is possible to rapidly reconstruct the internal elements morphology.

In this article, the results of some SPV tomographies regarding masonry elements are presented. The tests are carried out with the aim of establishing consistency and accuracy of this technique in determining the morphology of the investigated elements. The influence of investigation points number and noise smoothing is taken into account, too. At first, the results of a tomography derived from synthetic data of an ideal section are shown. Then, the SPV tomographies of some masonry specimens and of elements sections of a real case study are illustrated and compared among them.
