Macroscopic analysis of the bead assemblage from the South Arabian port of Sumhuram,Oman (seasons 2000–2013)

The city of Sumhuram (300 BC–AD 500) is the most important pre‐Islamic settlement in Dhofar, southern Oman. Since the time of its discovery it was evident that its commercial vocation placed it within a complex system of exchange between India and the Mediterranean. Sumhuram was a key site of the kingdom of Hadramawt, built in a place that was geographically strategic to control the most important Indian Ocean trade routes. The importance of the site made the bead assemblage exceptionally rich in materials, technologies used in the production, and provenance. The study of the relationship between materials and shapes, necessary for the creation of a specific typology, has revealed a number of trends. These, in connection with the reference stratigraphy have, in some cases, enabled the identification of differences on a chronological basis. Furthermore, it is possible to detect different uses of materials in different areas of the city. The variety of imported products (raw materials and products) once again underlines the importance of this city‐port in the international maritime trade and its strong connections with India.     

Rafael Pinedo’s Trilogy: Dystopian Visions and Populist Thought in Argentina’s Turn-of-the-century Narrative

The three short novels written by Rafael Pinedo (Argentina, 1954–2006) before his untimely death are increasingly attracting the attention of academic researchers, not only because of their complexity but also because of their take on Argentine politics and ideology. The following article analyzes how these novels operate within what Tom Moylan defined as a critical dystopian narrative. By narrating each story as a future world in agony, where all social interactions are described with a militant pessimism, the novels envisage the consequences of the populist’s policies grip on the country’s social and cultural environment. I argue that Plop (Casa de las Américas Prize 2002), Frío (Finalist for the 2004 Planeta Prize), and Subte can be read as a trilogy since they propose a radical thought experiment about the limits of the social and cultural practices of populist policies, as well as a mise-en-scène of its hijacking and betrayal of utopian values. The article also underlines how, despite its pessimistic tone, the novels offer a glimmer of hope by returning to basic concepts of community and empathy.     

Chinese manufacturing entrepreneurship capital: evidence from Italian industrial districts

The purpose of this paper is to obtain a better understanding of the presence of Chinese manufacturing entrepreneurship in industrial districts compared to other Italian local economies. Statistical data are used to uncover where Chinese manufacturing entrepreneurs localize their businesses and to what extent this localization is an innovation within the geographical pattern of industrial districts. Data on Chinese manufacturing micro-enterprises (i.e. with less than 10 persons employed) started up in years 2005–2007 and 2008–2010 are cross-tabulated by industrial districts and other local economies to investigate their change over time. The empirical findings show a dominance of industrial districts: those located in Tuscany are on top and Prato district ranks first.     

Anselm Kiefer: a study of his artistic materials

The style of the contemporary German artist Anselm Kiefer is highly innovative and unconventional and is characterized by the use of diverse materials that he selects and combines according to the emotions that they stir in him. The conservation and preservation of works by Kiefer are particularly difficult tasks because of the heterogeneity and, in some cases, the incompatibility of the materials used; therefore, a thorough characterization is crucial before any intervention is considered. In this paper, we report the results of an investigation on a fragment from a multimaterial work and on samples from the paintings Bohemia Lies by the Sea and Die Größe Fracht. The large fragment was cut by the artist himself from a work in progress and is considered destitute of any artistic value; therefore, it was possible to sample it extensively. This fragment and the samples from the Die Größe Fracht and Bohemia Lies by the Sea paintings were analyzed by ultraviolet (UV) fluorescence imaging, fiber optic reflectance spectroscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance, Raman spectroscopy, X-ray diffraction, gas chromatography-mass spectrometry, and pyrolysis gas chromatography-mass spectrometry. This multitechnique approach allowed us to fully characterize and identify pigments, dyes, and organic components that reflect the diversity of the materials typically chosen by the artist. The results are evaluated in the context of the interview that Antonio Rava had with the Anselm Kiefer in 2000.     

Luminescence Dating of Monumental Stone Architecture at Chavín De Huántar,Perú

Optically stimulated luminescence (OSL) is applied to quartz extracted from mud mortar collected from Chavín de Huántar, an early Andean monumental center. The samples appear to have been only partially exposed to sunlight during construction, so a minimum age model is applied to equivalent dose distributions. Complications, including complex radioactivity, low sensitivity of the quartz, and limited sample, prevent high precision, but the 14 dates obtained cluster around 1000 BC largely in agreement with radiocarbon assays on charcoal also collected from the mortar. Results suggest a relatively rapid construction for the monument. This work develops OSL as a method for directly dating architectural mortar.     

Production of the Roman Cement in Italy: characterization of a raw material used in Tuscany between 19th and 20th century and its comparison with a commercialized French stone material

An experimental approach in order to investigate the possibility that some Italian limestones were used for the production of Roman Cement is proposed. Three types of Pietra Alberese, a marly limestone used since Roman times for the production of “lime” in Tuscany (Italy), were selected. By burning of these stones, specimens of binders were realized. The characteristics of these binders were compared with the binder obtained by burning a French marly limestone commercially used for the production of Roman Cement.

All samples of carbonate stones were preliminarily characterized from the chemical, mineralogical, and petrographic point of view. The colorimetric coordinates were measured on both rock samples and hardened binder samples. The analysis carried out shows that Pietra Alberese with an high content of clay minerals develops a similar microstructure with respect to that developed by the French marly limestone used for the production of Roman Cement.     

The Non-Sense of an Ending

This article contributes to the scholarship on Portuguese writer José Cardoso Pires as well as the study of the neorealist short story in Portugal. It analyzes the ending of the neorealist short story as a moment of utopian projection and draws a comparison with Cardoso Pires's short story endings. This study demonstrates that Cardoso Pires displaces the ending of the story as a moment of concordance to a moment of continuing crisis. The author suggests that through the design of problematic narratorial voices that advance ambiguity and irony, Cardoso Pires requires from the reader an engagement with the text that mirrors the writer's engagement in society.     

Geography of belonging: nostalgic attachment,transnational home and global mobility among Romanian immigrants in Spain

This article explores how human global mobility is linked to a sense of home and belonging and outlines ways in which European Union (EU) enlargement could contribute to broader debates about migration, both empirically and theoretically. To accomplish this aim, I use the context of Romanian migration to Spain. Since EU enlargement in 2007, Spain has emerged as a major destination for Romanian migrants. The main argument of the paper is that transformations in the EU over the past 20 years through its open border policy have changed migrant workers into EU movers, and this change affects people's perceptions about sense of home. This analysis is prompted by a qualitative and narrative turn in migration studies, and an emphasis on new mobility pathways in accounting for the embodied dimensions of migration. Key to the paper is an analysis of how people can maintain a sense of home while being on the move. It attempts to demonstrate that migrants' experiences of belonging in their host country may vary greatly depending on the time of movement, the politics of EU borders, the nature of mobility and personal and individual circumstances.     

The Perineuronal Net: A Weapon for a Challenge

Theories and data do not always fit and sometimes are sources of conflicts among scientists. This is the case of a morphological structure, the perineuronal net, which was denied on the basis of an ideological conflict between two giants of neurosciences: Camillo Golgi and Santiago Ramón y Cajal. The perineuronal net is a reticular structure enveloping many neurons. Originally reported by Golgi in 1893 and 1898 and confirmed by several authors before the turn of the century, the perineuronal net was used by Golgi to support the reticular theory of the organization of the nervous system. Ramón y Cajal, the paladin of the neuronal theory who had also observed this anatomical structure, denied its existence suggesting that it was a fixation artifact. After Cajal's statements, only a few Italian scientists continued to work in this field, and after the 1930s the perineuronal net was forgotten. Only the recent advances in histochemical and immunocytochemical technology confirmed the existence of this structure opening new fields in functional neuroanatomy and neuropathology.
