A study by thermal treatment and X-ray powder diffraction on burnt fragmented bones from tombs II,IV and IX belonging to the hypogeic necropolis of “Sa Figu” near Ittiri,Sassari (Sardinia,Italy)

In the course of an anthropological investigation of three tombs of the hypogeic necropolis of “Sa Figu” (near the village of Ittiri in North Sardinia, Italy), numerous burnt bone fragments were collected. In particular, from the whole necropolis we selected a tenth of long bones from tomb IV, a small fragment of femur from tomb II and four fragments belonging to tomb IX. The aim of this work is to determine a temperature range to which the bone fragments were heated, in order to assess a funerary cremation which was presumably used at that time to quickly and hygienically eliminate the flashy parts of deceased people rather than a purification rite with fires inside the sepulchres. We attempted to evaluate the range of temperature to which the bones were likely subjected, making a joint use of thermal treatment and powder X-ray diffraction investigations. From our X-ray line broadening results carried out with a modern approach (Rietveld method), it emerged that a group of five fragmented burnt bones (one specimen belonging to tomb IV, the other four from tomb IX) were subjected to a heat treatment in a temperature range from 600 and 750 °C. Conversely another group of bones (belonging to tombs II and IV) turned out to be subjected to temperatures not higher than 250 °C.     

Two Byzantine Albanian icons: a non-destructive archaeometric study

The present work is part of a project aimed at studying the pigments and painting techniques used by Albanian iconographers to produce Byzantine and post-Byzantine icons dating from the fourteenth to the nineteenth centuries; the state of conservation of these icons was also explored. Inorganic pigments are identified by means of X-ray fluorescence, reflectance spectrophotometry and UV fluorescence analysis. These analysis techniques were performed to discriminate between pigments on the basis of their typical features. Moreover, the study of the optical properties of paintings is of fundamental importance for correct restoration. This work enabled us to recognise the palette used in two artworks by anonymous painters of the fourteenth and fifteenth centuries. Only three small samples were taken from the edge and the back of the wooden tables in order to achieve information on preparatory layers. Twelve to fourteen non-destructive measurements were made to characterise the palette used by the two anonymous painters.     

‘We Can Always Go Back Home’: critical lessons in helping to safeguard and promote the Singing and Praying Bands living tradition

Abstract

The article examines the process of promoting, with a view to safeguarding, the centuries-old Singing and Praying Bands living tradition, an African American musical and spiritual expression that is distinctive to the Chesapeake Bay region of the US. Discussed within the context of US public folklore, the process is understood as a co-intervention, representing an active partnership between the Bands’ community and public folklorists (including the authors) in attempting to reach new members as a means of keeping it alive. The article underscores the need for ‘bottom-up’ approaches in safeguarding living cultural traditions, bringing to light the potential strengths of public folklore work and the benefits its theories and methodologies can bring to the intangible cultural heritage discourse. Moreover, it analyses how community agency has been exercised, and community needs accommodated, through the dialogue-driven, collaborative intervention process. It also investigates how a nuanced view of ‘authenticity’ has been shaped, with regard to changes the living tradition has undergone, and is currently understood by those who embody it.     

Cultural Heritage Documentation and Conservation: Three-Dimensional (3D) Laser Scanning and Geographical Information System (GIS) Techniques for Thematic Mapping of Facade Stonework of St. Nicholas Church (Pisa,Italy)

This article reports the mapping of the stones, including marbles and brick masonry, used for building the facade of the medieval Church of St. Nicholas (XI century ad), one of the most interesting churches in Pisa, due also to the nearby famous octagonal bell tower. Mapping of stone materials was performed using a computer-aided design (CAD)/geographical information system (GIS) software package for storing and processing spatial information of the ashlars, obtained using three-dimensional (3D) laser-scanning data, combined with high-resolution images, and stone-to-stone observations. Based on collected data, the facade of the Church of St. Nicholas appeared mostly composed of rocks belonging to the metamorphic Tuscan sequence, quartzites, and marbles from Mt. Pisano area. Other types of rocks were also observed, as black limestones quarried at some kilometers northwest from Pisa in the Monti d’Oltre Serchio area, white Apuan marbles and Macigno sandstones. Conversely, intarsia appeared mainly made up of serpentinite and, subordinately, red limestones laid in white Apuan and Mt. Pisano marbles.

Institutional contradictions and attempts at innovation. Evidence from the Italian urban facility planning

Spatial planning affects the way in which cities are created and developed, as well as their economics and welfare. It does so by constructing institutional frameworks that frequently undergo states of contradiction and demands for adjustment and revision. This situation is particularly evident by looking at the way in which urban facilities have been planned during the twentieth century. The article explores the issue of urban facility planning in Italy by taking into account the adaptations of the institutional framework governing and regulating their supply. In particular, it explores the central contradictions which guided reforms and revisions of urban facility planning in Italy, starting from the post-war period until now, and the main problems left unsolved after years of attempts at innovation aiming at a more flexible and quality-oriented approach. In order to contribute to this debate, specific policy implications and devices are presented.     

Two online surveys of Italian Internet audiences: A summary of findings

This article describes the main results of separate online surveys on two partly differentiated Italian Internet audiences. It argues that the two show more traits in common than dissimilarities and that their common characteristics are widely shared by the millions of Italian Internet users. On a comparison of the sample to the country as a whole, it emerges as better educated, more open-minded, more affluent, and young to middle-aged. These Internet audiences do not trust television, they rely on the Internet to provide them with news, entertainment, goods and services, and they are quite similar to other Internet users elsewhere in western Europe.

Use of Pushover Analysis for Predicting Seismic Response of Irregular Buildings: A Case Study

Structural irregularity undermines capability of conventional methods for 2D pushover analysis to closely approximate results from inelastic dynamic analysis. In recent years, different methods have been developed to overcome such limitation and their suitability has been checked with reference either to idealized building models or to geometrically simple tested structures. In this paper, suitability of one such method, proposed by Fajfar et al. [2005] Fajfar, P., Maru?i?, D. and Perus, I. 2005. Torsional effects in the pushover-based seismic analysis of buildings. Journal of Earthquake Engineering, 9(6): 831–854. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], is evaluated considering an existing school building which presents both vertical and plan irregularities. Types of irregularity encompass not only those usually considered by seismic codes but also those deriving from a bad conceptual design and construction inaccuracies, very frequent at the year of construction (1974). It is found that, even under such complex irregularity conditions, this ‘modified’ pushover analysis correlates well results from inelastic dynamic analysis almost up to failure, since, in most cases, its predictions of interstorey drifts and plastic rotations are conservatively close to values from inelastic dynamic analysis. Even failure mechanism, consisting of a floor mechanism at the third level, is correctly predicted, thus demonstrating adequacy of such method for actual framed structures.
