Firing technique characterization of black-slipped pottery in Praeneste by low field 2D NMR relaxometry

This study was aimed at individuating characteristics related to the pottery’s firing technique of Classical Roman producers, through the low field single-sided NMR relaxometry. The approach is based on a recent method of analysis, the correlation of the longitudinal and transverse NMR relaxation times of a liquid probe (in this case distilled water) filling the porous system of ceramics. The analyzed findings form two homogeneous classes with dating and place of production well established through the producer trademarks. Pottery findings belong to the black-slipped pottery productions of the Latin ancient city of Praeneste between third and second century B.C. and have been attributed to two different ”patriziae” production families: gens Samiaria and gens Trebonia. A further fragment with Greek kylix style, found in the same archaeological area, has also been analyzed, in order to understand if it had been imported from Greece, or made in Praeneste in imitation of the Greek style.     

Children and Print Visual Culture During the Chilean Popular Unity Government

This article analyses the visual figuration of children during the Chilean Popular Unity government (1970–1973) in a diverse archive of photographs, posters, album covers, magazines, and comics. First, it reads the realist representation of children in photography, which emphasises the dramatics of poverty as a form of establishing a photographic “civil contract” (Azoulay, The Civil Contract of Photography, 2008). Second, it interprets posters and texts concerning the Allende government’s Plan de Leche (Milk Plan) as an affirmative biopolitics. It concludes by showing that the children on illustrated posters are the idealised version of childhood projected by adults as a way of imagining a coming community.     

The "Metaphor of Life": Herder's Philosophy of History and Uneven Developments in Late Eighteenth-Century Natural Sciences

The origins of the evolutionary concept of history have normally been associated with the development of an organicist notion of society. The meaning of this notion, in turn, has been assumed as something perfectly established and clear, almost self-evident. This assumption has prevented any close scrutiny of it. As this article tries to show, the idea of "organism" that underlies the emergence of the evolutionary concept of history, far from being "self-evident," has an intricate history and underwent a number of radical and successive redefinitions from the mid-eighteenth century up to approximately 1830 (the heyday of Romanticism and the period in which the first modern "philosophies of history" took form). More specifically, this paper traces some of these transformations in order to contextualize and shed some new light on Herder's philosophy of history and the complex process of its inception—a process that was not concluded by the end of his intellectual career. As the article shows, Herder did not actually succeed in solving some key problems involved in an evolutionary concept of history. The difficulties he found were analogous to those that emerged at that very moment in the development of a dynamic, onto-genetical theory (that is, a theory of the embryo's transformation), and both were ultimately linked to the combination of some uneven developments produced in the natural sciences of that time. Herder's philosophy of history thus appears as a paradoxical (and highly unusual, seen from a epistemological point of view) case of a system of thought that formulates problems which it is still radically unable to solve, lacking the tools to devise a possible solution for them.     

Chemists,engineers and entrepreneurs the chemical institute of sarrià's impact on Spanish industry (1916–1992)

This paper analyzes the influence the Chemical Institute of Sarrià (IQS) ‐a private institution devoted both to the education of chemists and chemical engineers and to applied research‐ has had on Spain's chemical industry from 1916 onwards. The research reported is based upon three data sources (articles on industrial chemistry published by the IQS’ journal Afinidad and M. Se. theses; IQS graduates’ industrial activities; and technical services carried out by the Institute's staff for several companies). The main conclusion is that the IQS has had a remarkable impact on Catalan and Spanish industry. Although there are no other similar studies on Spanish scientific and technical institutions, the IQS case confirms that technical education and institutionalized research have a positive impact on the economic and industrial development of “latecomers” like Spain.
