Isotopic Composition of Lead in Copper Ores and a Copper Artefact from the La Profunda Mine (León,Spain)

This paper continues the characterization of the lead isotopic fingerprint of ancient copper mines in the north‐west of Spain. In this work, the lead isotopic compositions found in copper ores from the La Profunda mine are presented. Azurites and malachites sampled from this deposit were subjected to lead isotope analysis by multicollector ICP–MS. The results showed a clear radiogenic lead signature compatible with the presence of uranium‐rich minerals (such as zeunerite) in the same mining complex. Moreover, a rare copper artefact, found in the galleries of the mine during its modern exploitation, was also analysed and showed that local mineral was used for its manufacturing.     

Cost Efficiency,Urban Patterns and Population Density When Providing Public Infrastructure: A Stochastic Frontier Approach

Relying on stochastic frontier analysis we propose a methodology to study the technological characteristics and cost efficiency levels related to the provision of public infrastructure for basic utilities. The methodology assumes a cost minimizing behaviour on the part of public officials when planning the construction of local infrastructure, which is represented by way of a flexible translog cost function. Introducing relevant definitions of scale economies, associated with larger numbers of inhabitants and dwellings, as well as economies of density, brought about by reductions in urban dispersion, we analytically determine the optimal population densities for which average cost is minimized. We illustrate our model with the water cycle sector, including water distribution, sewage collection and cleansing of wastewater, and considering data at the municipality level for the Spanish region of Castilla y León. The obtained results indicate potential cost savings in the form of decreasing average costs, as relevant scale and density economies are present, along with large inefficiency levels. Relevant policy guidelines favouring larger and denser urban sizes are drawn, as the observed cost excess is the result of a general suboptimal urban size in terms of population density, and the negative effects of dispersed settlement patterns.     

Gianrinaldo Carli at the centre of the Milanese Enlightenment

Gianrinaldo Carli was a central figure in the origin of the Milanese Enlightenment of the late eighteenth century. Carli's political career as well as his works connected him both to the mid-century reforms by Pompeo Neri and to the times of Beccaria and the Verri brothers—the heyday of Lombard intellectual life in Europe. Not originally from Lombardy, but from the Venetian periphery, Carli became an erudite scholar of witchcraft and magic and an influential functionary of the Habsburg administration in Milan. He remains most famous for his works on money and his contributions to the journal Il Caffè. Most of his later political writings, which were widely circulated in Italy following the American Revolution, originated in debates with Pietro Verri over the nature of Natural Law, of the Social Contract, and the relationship between patriotism and cosmopolitanism. They illustrate key aspects of Lombard political culture of the 1780s: a culture that was critical of Rousseau, trustful of the reformist experience and supportive of Enlightened Absolutism. Within this context, Carli's works have traditionally been difficult to place.     

Urban development in peripheral regions of the New Europe: The case of Vigo in Galicia

The paper discusses the development of peripheral cities and regions in a world where economic integration is growing. The paper argues that the development of peripheral cities and regions depends on their development potential and accessibility to markets. Their sustainable development, however, lies in the functioning of the forces of development: the organization of the productive system, the diffusion of innovation, the territory's urban development and the change and adaptation of the institutional system. These are forces that govern the economic growth process, generate externalities, and reduce production costs through reciprocal interaction. The paper's discussion is based on the analysis of the dynamics of the city of Vigo in Galicia, a peripheral region of the European Union.

Law as an anti‐value: Justice,violence and suffering in the logic of becoming (Respond to this article at http://www.therai.org.uk/at/debate)

Anthropologists are chronologically only the latest to have adopted justice (and injustice) as an object of (critical) inquiry. Even among anthropologists, however, the radical critical cry that law is the instrument par excellence of control and repression, has today fallen out of fashion. Starting from the Afghan case, in this paper I reflect on law as a potential source of violence and as an anti‐value – in the sense of being in antithesis with accepted social values – in the contemporary global scenario. My focus here is neither on the uses that can be made of law nor on the outcomes of its interpretation and application. Rather, I am interested in what law can generate when it betrays social values and sentiments of justice.     

Use of robust methods to determine quadratic surfaces: application to heritage

3D surveys of archaeological elements and the construction of virtual models enable us to reconstruct historical sites. They provide useful data to select specific building processes.Photogrammetry and Terrestrial Laser Scanning (TLS) are the most common techniques to obtain synthetically heritage models. These techniques provide massive data which can only be managed by replacing them by primitive shapes, thereby obtaining more simple models and the explicit geometry of the element. Statistical and robust methods are used for this substitution, thereby avoiding the common errors due to measuring. Of these methods, the most widely used are the least-median-of-squares (LMedS) and the RANSAC method.Another computation method consists in recursive processes based on evolutive-type algorithms to adjust the model to the data captured.This paper describes two surface computation methodologies to determine the modelling of a column shaft located in temple G of the archaeological park of Selinunte (Sicily).     

Vulnerability Index: A New Approach for Preventive Conservation of Monuments

A new approach is developed for vulnerability analysis of monuments based on a matrix model and the relationships with static and structural factors, climatic conditions, air quality, urban planning and social agents for preventive conservation of cultural heritage in urban centers.

The objective is to provide tools for decision-makers in the current recession to allow them to prioritize strategies for cultural heritage preservation in a town, where territorial policies are applied and regions where restoration budget is distributed. This new tool allows to classify monuments in order to prioritize restoration and is useful in deeper analysis associated to risks assessment.

The degradation of building materials and structures is mainly due to deterioration caused by structural instability, weathering, pollution, and anthropogenic damage. The vulnerability approach of each monument (vulnerability indexes) was calculated, based on a Leopold matrix that depends on intrinsic variables and the life of the monuments. For the very first time, the influence of different deterioration agents has been balanced with a Delphi forecast based on architects’ opinions.

The result is a new pre-Artificial Intelligence tool that enables users to reproduce human reasoning to study relations between vulnerability factors, risk factors, and the historical parameters of the monuments.
