The Structure and Chemical Composition of Wall Paintings From Islamic and Christian Times in the Seville Alcazar

Wall paintings from the Islamic epoch (10th to 12th centuries) and the Christian monarchy (14th to 16th centuries) have been recovered in discarded materials and on walls after reconstruction works in the Seville Alcazar. These paintings have spent centuries underground or under a plaster coat. Portable X‐ray fluorescence (XRF) and combined XRF/X‐ray diffraction (XRD) were employed in situ, as well as scanning electron microscopy (SEM–EDX), grazing angle incidence XRD and micro‐Raman spectroscopy, on cross‐section samples to fully characterize the materials in the wall paintings. Using these methods, the fresco technique was demonstrated, and many kinds of pigments were identified in accordance with the various periods of the history of the Alcazar, thus assessing the authenticity of all the wall paintings studied here.     

NEW ASPECTS OF THE MESOLITHIC‐NEOLITHIC CEMETERIES AND SETTLEMENT AT ZVEJNIEKI,NORTHERN LATVIA

The paper reflects upon recent international research at Zvejnieki in northern Latvia, a renowned complex of a burial ground and two settlement sites used in the Mesolithic and Neolithic. Since its discovery and first excavations in the 1960s, Zvejnieki continues to produce evidence that provides new grounds for understanding mortuary practises and ancient lifeways. This information is relevant for other contemporary sites in Europe revealing new and hitherto unexpected elements of burial traditions. It is suggested that the Zvejnieki population was partly mobile, and the site was one of the places to bury the dead. The ancestral link was established through transportation and use of occupational debris from more ancient sites and through the incorporation of earlier burial space or even burials into the new graves. The depth of a burial also appears to be a significant variable in ancient mortuary practices.     

Testing Transferability: Quantitative Evaluation of Labor Market Area Definition Methods in Three Contrasting Countries

Sub-national economic policies increasingly use labor market areas (LMAs) rather than administrative areas for analysis and implementation. How a set of LMAs was defined influences the results of such analyses, and so accurate policy delivery needs appropriately defined LMAs. Multinational bodies need comparable LMA definitions in many countries, calling for a definition method that is transferable across national boundaries. This article applies quantitative metrics to evaluate LMAs defined in three contrasting countries by three methods that represent the main methodological approaches. The deductive approach—based on a center and hinterland—is too inflexible to deal with differing geographical circumstances and cannot cope with statistical zones that are very small, or do not respect settlement structure. The alternative inductive methods tested define appropriate LMAs in each country, with the newer method performing slightly better in statistical terms. The article also exemplifies the usefulness of the metrics for comparisons of alternative regionalizations.     

A Roman Skeleton with Possible Treponematosis in the North‐East of the Iberian Peninsula: A Morphological and Radiological Study

The main goal of this paper is to describe and discuss pathological lesions observed in a Roman skeleton (between 2^nd and 3^rd century AD) from the north‐east region of the Iberian Peninsula (St Nicasi 18–24 site. Gavà, Barcelona), which may be compatible with treponematosis. Most of the skeleton, with the exception of the neurocranium, was recovered. Only the left tibia was affected, whereas the rest of the recovered skeletal remains were unaffected. Macroscopic examination revealed a male individual between 25 and 30 years of age at death with a sabre‐shaped left tibia. The proximal half of the diaphysis was pitted and the bone overall enlarged. The surface of the tibia showed occasional vascular impressions where, in some instances, small raised plaques of new bone appeared to bridge over them, specifically in the most affected area of the proximal half of the tibia. No destructive lesions were observed. Radiographic examination and gross inspection at the cross section of the tibia showed encroachment into the medullary cavity of coarse cancellous bone and cancellization of the cortex. The observed lesions indicate that the tibia was affected by a chronic infectious disease. Differential diagnoses were considered, and these included other infectious diseases, fibrous dysplasia, Paget's disease, chronic varicose ulcers affecting bone and trauma, with the conclusion that the disease affecting the tibia could have been treponematosis. This could be significant in the history of the treponematoses being one of the oldest examples of treponematosis in pre‐Columbian Europe. Copyright © 2011 John Wiley & Sons, Ltd.     

The origin and construction of pre-Hispanic mounds in the Upper Delta of the Paraná River (Argentina)

Pre-Hispanic mounds, known as “cerritos,” “cerritos de indios,” or “aterros” across southeastern South America, are one of the most conspicuous and well-studied cultural manifestations in lowlands archaeology. Nevertheless, in the Upper Delta of the Paraná River, mounds are rarely studied, and even their anthropic origin is under debate. This could be related to the fact that anthropogenic mounds are located on a floodplain where other “mound-like” natural geoforms (generated by fluvial processes) are also present. In addition to this, the natural geoforms also contain evidence of Holocene human occupation (sherds, bones, charcoal, humans burials, etc.), which can lead to interpretive errors of their origin and formation. Thus, this project set out to determine the genesis and evolution of these mounds and also to identify the cultural occupation and transformation of natural landforms found in the area. In this article, natural and anthropogenic systems and processes were identified and characterized through the application of proxy record analysis (i.e., sediment composition, stratigraphy, micromorphology, silica bodies and chronological analysis) at the Los Tres Cerros archaeological locality in the Upper Delta of the Paraná River of Victoria County, Entre Ríos Province, Argentina. This analysis allowed for the recognition of natural anthropogenic interfaces, such as the “pre-mound” occupation as well as evidence of cultural activities such as mound construction, between 1,000 and 500 ¹⁴C years bp. These findings were integrated into current research on the variability of mound construction during the Late Holocene in the lowlands of South America.     

Participation in Multiple Decision Making Water Governance Forums in Brazil Enhances Actors’ Perceived Level of Influence

The Ecology of Games Framework (EGF) draws attention to the intertwined nature of different forums in a given policy setting and how this affects governance outcomes. In this article, we associate the EGF with the literature on power asymmetries, in order to investigate hypotheses of actors’ perceived level of influence in a forum. Focusing on the Paraíba do Sul river basin committee in Brazil, we specifically explore actors’ participation in multiple forums, time spent participating in the basin committee, and actors’ degree of involvement in the committee as factors that might explain actors’ level of perceived influence in the forum. The findings suggest participation in multiple forums is a key driver of perceived influence and thus highlight a way to challenge traditional power asymmetries. More research, however, is needed to determine to what extent perceived influence is affecting decision‐making processes and governance outcomes in the Paraíba do Sul river basin committee.     

Ethics of care,emotional work,and collective action of solidarity: the Patronas in Mexico

In this paper, we examine the mobilization of the Patronas, a group of Mexican women who have fed thousands of Central American migrants over the past two decades. We argue that the Patronas’ work of feeding and caring for migrants goes beyond essentializing these women’s work as just housewives, mothers, and caregivers. Furthermore, we assert that through these care activities, the Patronas exert a feminist ethic of care that is understood as a set of practices based on trust, reciprocity, and solidarity. The Patronas’ praxis of caring for the migrants resonates with people and attracts hundreds of volunteers to join these women’s emotional and nurturing work leading these women and volunteers to participate in a political practice of solidarity. In this paper, we articulate three key findings: (1) the interplay between the Patronas’ emotional work and the ethics of care, (2) the emergence of a collective act of solidarity around the Patronas’ caring work that leads hundreds of volunteers to visit these women and join them, and (3) the kitchen as a place where the collective act of solidarity begins and where the Patronas experience their personal transformation. Drawing on ethnographic fieldwork, this study contributes to further our understanding of the interplay between Latin American women’s participation in social movements, emotional work in these movements, and the ethics of care.     

The Upper Paleolithic Rock Art of Iberia

Nearly 200 rock art sites of Upper Paleolithic age are currently known on the Iberian Peninsula, in both caves and the open air. Over half are still concentrated in Cantabrian Spain and they span the period between c. 30–11 kya, but–tracking the course of human demography in this geographically circumscribed region–many of the images were probably painted or engraved during the Solutrean and, especially, Magdalenian. Dramatic discoveries and dating projects have significantly expanded the Iberian rock art record both geographically and temporally in recent years, in close coincidence with the growth of contemporaneous archeological evidence: cave art loci in Aragón and Levante attributable to the Solutrean and Magdalenian, many cave art sites and a few open-air ones in Andalucía and Extremadura that are mostly Solutrean (in line with evidence of a major Last Glacial Maximum human refugium in southern Spain), the spectacular Côa Valley open-air complex in northern Portugal (together with a growing number of other such loci and one cave) that was probably created during the Gravettian-Magdalenian periods, and a modest, but important increase in proven cave and open-air sites in the high, north-central interior of Spain that are probably Solutrean and/or Magdalenian. Despite regional variations in decorated surfaces, themes, techniques and styles, there are broad (and sometimes very specific) pan-Iberian similarities (as well as ones with the Upper Paleolithic art of southern France) that are indicative of widespread human contacts and shared systems of symbols and beliefs during the late Last Glacial. As this Ice Age world and the forms of social relationships and ideologies that helped human groups survive in it came to an end, so too did the decoration of caves, rockshelters and outcrops, although in some regions other styles of rock art would return under very different conditions of human existence.
