The world's most powerful number: An assessment of 80 years of GDP ideology (Respond to this article at http://www.therai.org.uk/at/debate)

Economic measurements and indicators play an important role in governance. As time passes, some of these indicators, like the gross domestic product (GDP), have come to shape our lives more than we can imagine. Here Lorenzo Fioramonti, the author of two books on economic indicators, is invited to reflect on the 80th anniversary of GDP.     

Economic Regionalism and Social Stabilisation: the International Labour Organization and Western Europe in the Early Post-War Years

The International Labour Organization (ILO) played a concrete role in shaping the mechanisms of international economic co-operation created in Western Europe in the early post-war years. Its tripartite composition and orientation towards social dialogue were perfectly in tune with the productivist principles sponsored by the United States after the Second World War, which largely permeated European economic integration. Thanks to its solid know-how in the field, the ILO made a key contribution in promoting labour mobility, by helping the organisation and co-ordination of national employment services and vocational training systems and, most of all, by assisting institutions such as the Organisation for European Economic Co-operation (OEEC) and the European Communities in implementing freedom of circulation between their member countries. At the same time, in the mid-1950s it offered theoretical support to the economic liberalism on which the European common market was being modelled, arguing against claims for social harmonisation as a precondition to economic integration, and thus contributing to giving European co-operation the shape which still characterises it today.     

Mediterranean trade of the most widespread Roman volcanic millstones from Italy and petrochemical markers of their raw materials

The petrochemical study of millstones can contribute to improve the archaeological research into reconstruction of ancient communication routes and trade networks. Volcanic rocks are geographically restricted and rather rare in the Mediterranean regions, and during the Roman period Italian volcanoes were important sources of raw materials for millstones, so the task of determining their geological origin is relatively straightforward. The Italian vesicular volcanics most frequently employed for this purpose were: trachytes from Euganean Hills (Veneto), leucite-bearing lavas from the Vulsini Volcanic District (Latium), basic-intermediate leucite-bearing lavas from Somma-Vesuvius (Campania), silica undersaturated lavas from Monte Vulture Volcano (Basilicata), a rhyolitic ignimbrite from Sardinia and basic products from Mount Etna and the island of Pantelleria (Sicily). This paper contains a general outline of the trade network for each volcanic typology used for millstones during the Roman period – updated with data concerning the leucite-bearing lavic items discovered in the archaeological sites of the ancient Cuicul (now Djemila, Algeria) – together with a summary of their petrographic and geochemical features.     

Traces of a computational mind

The image of writing is singularly frequent in cognitivistic explanations of the functioning of mind, not only as a metaphor but also as a conceptual paradigm: the Turing machine, particularly, displays a complete structural isomorphism with the use of alphabetical writing. The Turing machine performs exactly the same operations carried out by a man writing with pen and paper and this depends on two reasons: 1. it has been conceived in image and likeness of the human concrete practice of writing; 2. it is the typical product of the western rationality, whose development has been made possible only by the specific features of the alphabetical treatment of information. This is useful to understand why the mind started being depicted as a writing machine just when the alphabet began spreading: a genealogical investigation will show how in mnemotechnics treatises and in Plato's and Aristotle's metaphysics we can find the very first foundation of every logico-symbolical model of mind.     

Shifting Bordering and Rescue Practices in the Central Mediterranean Sea,October 2013–October 2015

This counter‐mapping project illustrates the areas of intervention of different operations geared toward rescue and enforcement between 2013 and 2015, including the Italian Navy's “Mare Nostrum” search and rescue mission, the EU border agency Frontex's “Triton” enforcement operation, the humanitarian interventions of commercial vessels, and the action of civil‐society rescue vessels such as those operated by Médecins Sans Frontières (MSF—Doctors Without Borders). The project offers a spatial understanding of the Mediterranean border‐scape, the practices of rescue and enforcement that occur within it, and the risk of sea‐crossing at this particular moment. Through these maps, the Central Mediterranean Sea emerges as a striking laboratory from which novel legal arrangements, surveillance technologies, and institutional assemblages converge.     

Lega democratica and the making of Italy’s center-left

This article analyzes the history of the Lega democratica, a group of Catholic intellectuals active between 1975 and 1987, and its impact on Catholic debates in Italy’s Second Republic. Despite its small membership, the group’s heritage influenced Italy’s post-1994 center-left and shaped its leadership. Such relevance is explained by describing the Lega democratica’s legacy on four issues. First, on Catholic pluralism: the group was central to a decade-long failed attempt to reconcile different souls of the Italian Catholic laity, which anticipated the end of the Christian Democratic party. Second, after Aldo Moro’s murder the Lega democratica theorized the impossibility of a ‘historic compromise’ between Communists and Christian Democrats: such a development framed their post-1994 attitude. Third, the group’s history reveals a growing generational split on how to achieve political reform (mediation vs. rupture). Finally, the emerging idea of a ‘primacy of civil society’ in the political sphere partly defined the Ulivo coalition’s ideology.     

Marbles,granites and basalt used in the cruciform basilica of Abila (Decapolis,Jordan): archaeometric characterization and provenance

The provenance of granite, basalt, and marble used in building the cruciform basilica of Abila of the Decapolis, northwestern Jordan, is investigated using chemical and petrographic techniques. The basilica is dated to the late fifth or early sixth century AD. The stones were characterized using macroscopic traits in combination with optical microscopy, X-ray diffraction, and stable oxygen and carbon isotope spectrometry. These data were compared to the published databases for marbles, granites, and basalts used in antiquity. The comparison showed that the basalts are most probably local. The islands of Marmara (Proconessos-1), Turkey, are the primary source of the white marbles, while Paros island (Paros-2), Greece, is a minor source. The source of the green Cipollino marbles is Styra in the island of Euboea (Greece). The pink and gray granites are likely microasiatic from the Çigri and Kozak Dâgs, respectively, northwest Turkey.     

International regulation of historic buildings and nationalism: the role of UNESCO

This article focuses on the (ambiguous) relationships between nationalism and international regulation of historic buildings, namely, the activity of UNESCO in this field. It studies two different forms of UNESCO intervention: the creation of a list of world heritage sites of outstanding universal value, which includes several historic cities and buildings; and UNESCO Recommendations aimed at protecting historic urban landscape. The article shows that UNESCO seems to favour both political and cultural forms of nationalism and can significantly affect the nationalistic use of historic buildings and, more broadly, affect on the very idea of Nation and nationalism.
