An analysis of the Spanish ceramic tile industry research contracts and patents

In this work, we apply a systemic approach to the analysis of a particular geographic territory, the industrial district. We are particularly interested in analysing the interaction between the productive-technological environment and the scientific environment by an examination of research contracts and patents. Our analysis shows that R&D activity in the Spanish ceramic tile District Innovation System was mainly conducted by suppliers. Final producers’ innovation efforts were related to non-technological aspects and differentiation.     

The hinc et nunc of moral theology: Francisco de Vitoria’s lesson and the missionary experience*

In the sixteenth century, as moral theology was being consolidated as an autonomous academic discipline, theologians at the University of Salamanca, including the Dominican Francisco de Vitoria, began to incorporate current moral and political issues into their teaching agendas. Prominent among these issues were those arising out of the conquest of the Americas. Their students, a generation of university-trained missionaries, then went to work in Spanish possessions in the Americas and the Philippines. These missionaries and men of learning included the Augustinians Alonso de la Veracruz (in Mexico) and Martín de Rada (in the Philippines and China). As their world expanded, Vitoria's teachings were rendered fully intelligible in the confusing reality of the colonial enterprise, and these missionaries struggled to apply his lessons to the questions of conscience they encountered. The result can be considered a new chapter in the relationship between theological knowledge, the production of facts, and moral certainty, all against the backdrop of the territorial and economic expansion of Spain.     

The colors of the Fontana di Trevi: an analytical approach

During the last restoration of the Fontana di Trevi -Rome (2014–2015), it has been performed a diagnostic investigation to characterize the materials used to build and obtain the colors of the surfaces of some architectural elements of this fountain. According to the restoration teamwork needs, we focussed our efforts on the dome over the central statue of Oceanus, on the bas-relieves on the sides of the dome, and on the cliff where the water flows. Several samples were collected from these elements and therefore, they were subjected to an analytical approach including infrared spectroscopy, optical and scanning electron microscopy. The achieved results indicated the use of red earth pigments on the dome. The same pigment has been revealed on the bas-relieves, although their colors have an additional contribution due to degraded layers. Samples taken from the cliff showed a complex stratigraphy, although a white scialbo has been identified as original layer, testifying the intentions of the authors in term of color rendering. This information was essential for the restores in order to choose the proper intervention procedure for each investigated surface. The research testified the importance of an integrated diagnostic analysis to preserve the original colours of monuments and building.     

Evaluation of Structural Intervention in the Quartel das Esquadras,Almeida (Portugal)

ABSTRACT

The “Quartel das Esquadras” is an 18th century infantry barrack located within the limits of the bulwarked fortress of Almeida, in Portugal. An ongoing adaptive reuse project of the building aims to recover its full capacity and also its importance, by implementing a variety of new uses. The architectural intervention results in the need of the structure to withstand new and diverse imposed loads. As the current configuration of the structure will be altered, the main objective of this article is to evaluate the suitability of some of the proposed structural interventions. The current condition has been characterized following a multidisciplinary approach comprising historical research, visual inspection, non-destructive testing, and structural analysis to identify the possible sources of major structural problems. A portion of the building particularly affected by the alterations has been selected to carry out structural analysis. A comparative safety assessment of the selected area in both current and altered condition has been done through finite element modelling and nonlinear static analysis, resulting in an identification of the weaker points against the new implemented loads and alterations. Finally, proposals for the implementation of the studied intervention, as well as recommendations for future research and analyses, have been given.     

San Juan,the Fragile City: Finance Capital,Class, and the Making of Puerto Rico's Economic Crisis

This paper narrates Puerto Rico's fiscal and financial crisis through a reading of San Juan's urban landscape. We underscore the role of capital in the city, primarily embodied by the local capitalist class (the Criollo bloc) and foreign capitalists. Historically excluded from the manufacturing sector (dominated by US capitalists), the Criollo bloc accumulates its wealth by concentrating financial assets in the city. In times of crisis, the Criollo bloc resorts to the acquisition of new assets and asset exchange with foreign capitalists to remain solvent and provide short‐term solutions to the state's fiscal and financial limits. The survival of the local capitalist class, we demonstrate, is dependent on asset stripping. Drawing on Clyde Woods, we document how asset stripping unevenly redistributes wealth and risks along class and racial lines within a colonial economy. The finance capital/asset stripping basis of San Juan's economy renders it an extremely fragile city, we contend.     

An empirical evaluation of copper procurement and distribution: elemental analysis of Scioto Valley Hopewell copper

In prehistoric North America, artifacts of copper occupy a position of prominence in the Hopewell societies of Ohio’s Scioto Valley. These artifacts also represent the social contacts and long-distance interactions that brought copper to the Scioto Valley. Yet, our understanding of Hopewell copper acquisition, and the movement of copper artifacts within the social networks of the Scioto Valley and beyond, has been limited due to the limited availability of geochemical data concerning provenance and variability. We begin to develop the foundation for understanding these important social issues by analyzing the elemental variability of Hopewell copper through the use of laser ablation inductively coupled plasma mass spectrometry. We analyze 24 samples from four known copper source regions and 52 samples from 6 prominent sites in the Scioto Valley. Results suggest that a majority of the artifacts are consistent with sources in the Great Lakes, with a plurality classified as Isle Royale. However, 21% of Scioto Hopewell copper artifacts were most consistent with southern Appalachian sources. High elemental variability argues against simple models of copper acquisition and suggests that different social groups had access to a variety of copper sources through varying social networks. Native copper regardless of source seems to have been channeled along similar social and symbolic pathways. Our results suggest that instead of being derived from the struggle to access a specific source, value is derived from the social relationships represented by the copper and the connotation of exotic connection embodied in both style and material.     

Sex estimation using cervical dental measurements in an archaeological population from Iran

Sex estimation of skeletal remains is one of the major components of forensic identification of unknown individuals. Teeth are a potential source of information on sex and are often recovered in archaeological or forensic contexts due to their post-mortem longevity. Currently, there is limited data on dental sexual dimorphism of archaeological populations from Iran. This paper represents the first study to provide a dental sex estimation method for Iron Age populations. The current study was conducted on the skeletal remains of 143 adults from two Iron Age populations in close temporal and geographic proximity in the Solduz Valley (West Azerbaijan Province of Iran). Mesiodistal and buccolingual cervical measurements of 1334 maxillary and mandibular teeth were used to investigate the degree of sexual dimorphism in permanent dentition and to assess their applicability in sex estimation. Data was analysed using discriminant function analysis (SPSS 23), and posterior probabilities were calculated for all produced formulae. The results showed that incisors and canines were the most sexually dimorphic teeth, providing percentages of correct sex classification between 86.4 and 100 % depending on the measurement used. The combination of canines and other teeth improved significantly the level of correct sex classification. The highest percentages of sex classification were obtained by the combination of canines and incisors (100 %) and canines and molars (92.3 %). The present study provided the first reference standards for sex estimation using odontometric data in an Iranian archaeological population. Cervical measurements were found to be of value for sex assessment, and the method presented here can be a useful tool for establishing accurate demographic data from skeletal remains of the Iron Age from Iran.
