Characterization of concrete from Roman buildings for public spectacles in <Emphasis Type="Italic">Emerita Augusta</Emphasis> (Mérida,Spain)

The aim of this work is to characterize the original concrete from Roman buildings for public spectacles, theatre and amphitheatre, from Emerita Augusta, Mérida, Spain. An advanced knowledge of the Roman concrete composition is required for a reliable restoration and preservation of these ancient monuments. The concrete was studied through mineralogical (optical polarized microscopy and X-ray diffraction) and petrophysical (bulk and real density, open porosity to water and Hg, mechanical strength and ultrasonic velocity) analyses. With this work, it is possible to fill the gap that exists in this field and the characterization of the materials used in the Roman concrete from these two buildings, never previously studied, despite the significance of this archaeological ensemble, declared a World Heritage Site by UNESCO in 1993. The results allowed us to determine the composition of the Roman concrete and to infer the provenance of the aggregates used in these monuments.     

From Neo-Francoist Memory to Political Feeling in Narratives of Unearthing: Sánchez Dragó's Muertes Paralelas (2006) and Andrés Trapiello's Ayer no más (2012)

This article analyzes the novels Muertes paralelas and Ayer no más as representatives of two clearly defined perspectives within the Spanish twenty-first century narrative production on unearthing the past of Francoism. The symbolic construction of unearthing permits an investigation of the remnants of a neo-Francoist vision of the legacy of the civil war, while opening the view of a political feeling by which personal memory inserts itself most profoundly as a commitment to a more comprehensive and lasting closure of the past.     

Food for all: An agent-based model to explore the emergence and implications of cooperation for food storage

Abstract

A consistent access to food is paramount for humans at individual and group level. Besides providing the basic nutritional needs, access to food defines social structures and has stimulated innovation in food procurement, processing and storage. We focus on the social aspects of food storage, namely the role of cooperation for the emergence and maintenance of common stocks. Cooperative food stocks are examined here as a type of common-pool resource, where appropriators must cooperate to avoid shortage (i.e. the tragedy of commons). ‘Food for all’ is an agent-based model in which agents face the social dilemma of whether or not to store in a cooperative stock, adapting their strategies through a simple reinforcement learning mechanism. The model provides insights on the evolution of cooperation in terms of storage efficiency and considering the presence of social norms that regulate reciprocity. For cooperative food storage to emerge and be maintained, a significant dependency on the stored food and some degree of external pressure are needed. In fact, cooperative food storage emerges as the best performing strategy when facing environmental stress. Likewise, an intermediate control over reciprocity favours cooperation for food storage, suggesting that concepts of closed reciprocity are precursors to cooperative stocks, while excess control over reciprocity is detrimental for such institution.     

History manifested: making sense of unprecedented change

An essential element usually passes unnoticed in recent discussion about how history as an academic discipline is supposed to be relevant for the shaping of our public life. It is the concept of history itself (history as both the course of events and historical writing) that underlies the whole discussion, which also configures the two currently most influential and fashionable efforts to reinstate the public relevance of history: The History Manifesto, co-authored by Jo Guldi and David Armitage, and Hayden White's The Practical Past. In advising to turn to the past in order to shape the present and the future, both books rely on the familiar developmental view that characterised nineteenth-century thinking in general, and on which the discipline of history became institutionalised in particular. The author's main contention in this essay is that turning to this notion of history is not the solution for the problem of the supposed public irrelevance of professional historical studies, but the problem itself. The developmental view, based on a presumption of a deeper continuity provided by the subject of the historical process that retains its self-identity amid all changes, certainly suited the discipline of history when it was engaged in the project of nation-building. However, it hardly fits our present concerns. These concerns, like the Anthropocene, take the shape of unprecedented change, and what they challenge is precisely the deeper continuity of the developmental view. The discipline of history can regain public relevance only insofar as it proves to be able to exhibit a thinking of its own specificity which can nevertheless explain such unprecedented changes. What such historical thinking could provide is what the developmental view can no longer: the possibility to act upon a story that we can believe.     

Territorial Capital: Theory,Empirics and Critical Remarks

Territorial capital has gained considerable attention in the past few years. The aim with this work is to throw light on some underlying aspects of territorial capital research. The study focuses on the theoretical and empirical issues of territorial capital and highlights some critical remarks related to the topic. On the one hand, the focus of the study is on the comparison of concepts and approaches in connection with territorial capital; then an in-depth look is taken at “capital frameworks” related to the research field. On the other hand, a comprehensive overview is presented of empirical investigations by comparing the applied methods, dimensions and variables of territorial capital. An argument is also made for a critical assessment concerning the topic with regard to the sense and function of territorial capital in regional economics and local economic development and highlights some further dilemmas concerning the “properties of capital” and “territorial capital paradigm”. Finally, some suggestions are provided for the future of territorial capital analysis. The main result of the study is an own belief in the concept of territorial capital.
