A new calibration of the XRD technique for the study of archaeological burned human remains

A new calibration of human bones as a function of programmed temperature (200–1000 °C) and time (0, 18 and 60 min) is presented and discussed in order to investigate the issues related to the study of cremated bone remains by using the powder X-ray diffraction approach. The experimental results confirm the growth of hydroxylapatite crystallites as a function of the applied temperature, with a sigmoid behaviour that has been parameterized to the experimental data points. Particularly, it was observed that the thermal treatments for 60 min anticipate of about 100 °C the effects that are otherwise observed after the treatments for 0 min. The developed procedure was subsequently applied to cremated remains of various archaeological sites of Spain and supplied precise information not only about the temperature reached during the funerary rites, but also on the presumed duration for the cremation.     

Cosmopolitisme et transferts culturels le cas des Juifs allemands

During the XIX^th century, the socio-economic rise and cultural assimilation of the German Jews generated two contradictory tendencies: on the one hand, their integration into the German nation, which they pursued willingly; and, on the other, their cosmopolitanism, which resulted from their location at the center of a socio-economic network on a continental scale and a wide migratory movement. The Jews thus contributed to the development of a cultural concept ofMitteleuropa as opposed to the geopolitical and expansionist concept upheld by Pan-Germanism. German-Jewish cosmopolitanism found its expression on different levels: in the religious field, the school of the «Science of Judaism» (Wissenschaft des Judentums) became a model for the modernisation of Jewish culture in most European countries: in the economic field, emancipated German Jews consolidated their financial and commercial transnational network, which existed from the age of the «Court Jews» (Hofjuden); in the political field, radical German Jews played a leading role in the diffusion of Marxism as a universalist intellectual current, crossing national borders. Generally speaking, German Jews played a pivotal role in a process of cultural transfers stretched on more than a century. After Nazism came to power, German-Jewish cosmopolitanism took the way of exile, trying to preserve the legacy ofAufklärung.     

NEW URBAN POVERTY AND THE CRISIS IN THE CITIZENSHIP/WELFARE SYSTEM: THE ITALIAN EXPERIENCE

The paper deals with the working hypothesis and preliminary empirical research on longitudinal analysis of the new urban poor in large Italian cities. It begins by considering existing welfare provisions in Italy and the reasons why they are inadequate to the needs of the new urban poor, who are segments of an increasingly heterogeneous population hit by an accumulation of specific disadvantages, such as the socially isolated elderly with serious health problems, poorly educated young people with a low income family background, long-term unemployed adults who become in some areas professionally unemployable, migrants isolated from both local and fellow-countrymen networks. The paper then presents a preliminary analysis of data indicating the different typologies of new poverty in northern and southern Italian cities and discusses the problems raised for the Italian welfare system by the extension of these phenomena.     

Characterization of Materials and Artistic Techniques on Two 17th‐Century Neapolitan Wood Sculptures

Two sculptures of Gaetano Patalano, one of the most important Italian sculptors of the late 17th century, were analysed to study the stratigraphy, the organic and inorganic materials, and to distinguish the original layers from the repaintings. Samples taken from the Immacolata Concezione and from San Gaetano da Thiene (Santa Chiara church, Lecce, Italy) were studied by optical microscopy, μ‐Raman spectroscopy and Py‐GC–MS. Different binders and pigments were used for the preparatory layers on the different parts of the statues: the results demonstrate that Patalano mastered the various materials and techniques, and that his choices have allowed his carving ability to be emphasized.     

Declining,transition and slow rural territories in southern Italy Characterizing the intra-rural divides

As metropolitan areas around the world keep expanding, behind them, rural areas continue to be affected by greater rates of depopulation. This is not a new phenomenon: rural to urban migration has been reported in the developed world at least from the period between the two world wars. However, recent rural depopulation trends have dramatically intensified in both the developed and the developing countries worldwide. In planning literature, greater emphasis is placed on the “urban–rural” divide, that is, people leaving the countryside to look for better opportunities in urban areas. However, a growing body of literature points to the fact that not all rural areas are declining at the same rate. Indeed, some rural towns have managed to retain population and even to grow. Therefore, at least in developed countries, an “intra-rural” divide notion is emerging. To exemplify this notion, we have studied rural towns in Southern Italy.     

U-series and radiocarbon dates on mollusc shells from the uppermost layer of the archaeological site of KHB-1, Ra's al Khabbah,Oman

The archaeological site of KHB-1, Oman, has been investigated in order to improve the chronological knowledge of the site, which is dated to the beginning of the fourth millennium B.C. on the basis of the archaeological context. Mollusc shells of the genus Anadara, coming from the uppermost layers of the site, have been dated using two different methods, radiocarbon and U-series technique. The results of the two techniques date the last occupational phase of the site from the end of the fourth millennium B.C. to the beginning of the third millennium B.C.     

An X-ray Diffraction (XRD) and X-ray Fluorescence (XRF) investigation in human and animal fossil bones from Holocene to Middle Triassic

We examined by Rietveld refinement of X-ray Diffraction patterns a series of 61 human and animal fossil bones in an age range from present time to Middle Triassic (around 245 Ma). This approach, supplemented by elemental analysis according to X-ray Fluorescence, has permitted to obtain a quantitative evaluation of the mineralogical phases in the specimens, thus allowing to reconstruct the mineralization process involved. Concerning the apatite phase, after adopting a monoclinic geometry for the unit cell, the method permits to determine with fair degree of precision the unit cell volume, which is found to decrease in relatively short geological times as a function of the fluorine substitution process for the hydroxyl group –OH. After excluding the role of a high-temperature fire treatment to the bones, it is found that a certain linear correlation may exist over the geological time scale involved between the age of the specimen and the average crystallite size. This observation permits to use the XRD pattern as an evaluation of the age of the fossil, although the stratigraphic observations, where available, remain as the main reliable source for dating such biomaterials. The uncertainty related to this age estimation may be hardly better than 15–20% in absolute, because of various assumptions involved in the XRD methodology used and in the variability of the burial environment that may be subjected to discontinuous changes over the very long time of deposition.     

A generational attitude: young adults facing the economic crisis in Milan

Abstract

For almost 10 years there has been talk of the economic crisis affecting the European area, with more evident effects in the Mediterranean countries. Yet the expression ‘economic crisis’ has become too wide and blurred to be useful for describing how the current socio-economic conjuncture is affecting different categories of young people in different ways. Precariousness and reduced job opportunities, with their consequences for social mobility, constitute only the more explicit and raw evidence of the lived experience of the crisis among young people. Although families remain the all-solving institution, the consequences of the crisis are diversified according to the economic, cultural and social capital of each individual, to gender and generation position, and to subjective and contextualized perceptions. This article presents research conducted to investigate how young people living in the urban area of Milan locate, react, readapt and reinvent themselves in the present economic context by analysing their aspirations, expectations and practices. We develop a comparative analysis of the main structural bias (gender, education, social class position) in order to shed light on the effects and perceptions of the crisis among young people in the city of Milan.     

Liberal decorum and men in conflict: Rome, 1871 – 90

This essay examines court cases involving insult to a public official, which came before the local courts in Rome in the second half of the nineteenth century. It underlines the gendered character of this particular offence, which was committed almost exclusively by men. The analysis correlates two aspects of these cases: the first is the context of the offenses, characterized by the application of a detailed set of local police regulations, and experienced as a limitation of masculine personal liberty. The second aspect relates to the institutional organization of the police forces and the masculine identity of the officers themselves. The combination of these two elements during interactions between population and the police forces meant that the subjects' gender became more significant than other variables (such as social class), to the extent that these interactions took on the inflections of a performative ‘face-off’. In this way the variable of gender brings into question the traditional reading of public order in the Liberal era as the product of a policy of containment of the popular classes.
