Identifying pre-Hispanic water storages in agricultural areas of south-central Andes through diatom evidence

In the Andes, there are several pre-Hispanic irrigation networks with structures destined for water storage. However, it has not been widely discussed in archaeological research. This is probably due to their being difficult to identify. The aim of this study is to explore the use of diatom assemblage analysis as a methodological tool suitable to help in the identification and characterization of these ancient hydraulic structures. We analyzed two archaeological structures interpreted as water reservoirs from north-western Argentina (EH1 in Antofagasta de la Sierra and U-88R1 in Yocavil) and compared them to current reservoirs. The diatom species composition and the changes in the dominant ecological groups in the studied structures highlight different periods of hydraulic behavior. EH1 contained and stored water, but there were periods of time in which there was a lack of use or abandonment of the structure. However, the U88-R1 structure does not have diatom evidence of containing standing water for a prolonged time but presence of wet soils. Thus, the structure could have been used for other water management strategies. The results show that diatom analysis is a methodological tool with a high potential to study ancestral hydrotechnologies.     

When DNA can't help: The osteobiographical profile and stable isotope analysis as auxiliary tools for refining genealogical relationships,on the example of the Swéerts-Sporck family

Research into the family of the Counts Swéerts-Sporck raised doubts regarding their biographical data, particularly concerning a child who died in 1817, later identified as Philipp Swéerts-Sporck, and his siblings Joseph and Barbara. These were alleged to include a pair of dizygotic twins, but DNA could not be used to clarify their relationships. Carbon and nitrogen isotopes were therefore measured in their first permanent molars, whereas Philipp's biological age was estimated based on his skeleton. Philipp died at an older age than the written sources claim; an isotopic similarity was found between Joseph and Barbara, but Philipp differed.     

Results of micrometallographic analysis of metalworking tools in graves of metallurgists in Moravia/Czech Republic

The number of finds relating to metalworking, without evidence of mining and processing facilities, is very limited. In Final Eneolith graves of specialized metallurgists that have occurred, they contain a metal-founding or metalsmithing toolkit, whose origins were from eastern Europe (the Maykop, Yamnaya Culture). Such metallurgical tools may have reached central Europe as part of the so-called Yamnaya Package before the onset of the Bee Beaker Culture (BBC); and unlike the Pontic region, these two types of metallurgy separated here. There are found an accumulation of metallurgists' graves in Moravia, where the complete metalworking toolkit is deposited in a predefined place in richly furnished male graves with a distinctive funerary architecture that exhibit a clear relationship to the grave goods. EDX-analysis detected a high content of metals (Cu, Ag, Au, Au–Ag alloy) on all working surfaces of stone tools, grinders, and boar tusks used for the final treatment of their metal products. This makes us believe that the used artefacts were laid as symbolical objects in the graves of these craftsmen who perfectly knew these advanced technologies. Due to their knowledge, their social significance gradually rose and finally reached the level of social elites, who were usually buried in a spectacular manner, including the quantity of grave goods (Überausstattung) and the pars pro toto deposition in one part of the finds.     

Determination of the Fineness of Medieval Coins—Evaluation of Methods in a Case Study of a Medieval Pfennig

The original fineness of coins is very important information that can help us to understand the commercial situation in a wide historical context. This paper deals with a comparison of analytical methods suitable for the evaluation of the actual and original fineness of coins based on a detailed case study of a medieval coin sample. Both non‐destructive (i.e., scanning electron microscopy/energy‐dispersive X‐ray spectroscopy, X‐ray fluorescence, atomic force microscopy and hydrostatic weighing) and destructive (i.e., inductively coupled plasma – mass spectrometry and the Volhard titration method) techniques were used. The original fineness can be also deduced from knowledge of the internal structure of the coin (limited miscibility of copper and silver). A new analytical method based on a combination of a micrograph of the metallographic cross‐section with consequent image analysis was developed for determination of the original fineness. The proposed approach is relatively simple and provides reliable values. Sample heterogeneity and its impact on the determination of fineness are also discussed.     

Updating Numerical Models of Masonry Arch Bridges by Operational Modal Analysis

This article aims at presenting and discussing the strategies for updating the finite element numerical modeling of stone masonry arch bridges using operational modal analysis. The study comprehended three bridges: two old ones, the St. Lázaro and the Lagoncinha bridges, and a recently constructed bridge in Vila Fria, Portugal. Updating of the bridge models is performed by comparing the numerical and experimental modal parameters. Three-dimensional detailed numerical models are used to perform modal analysis of the bridges. Experimental modal identification of the bridges is based on the measurement of their acceleration responses during normal operation. The assigned material properties are also based on available results obtained from in situ and laboratory tests and on the results of visual inspection and historical research carried out for both old bridges.     

Habermas’s Theological Turn and European Integration

Abstract

Jürgen Habermas’s recent work is defined by two trends: an engagement with the realm of the sacred and a concern for the future of the European Union. Despite the apparent lack of connection between these themes, I argue that the early history of European integration has important implications for Habermas’s conclusions about the place of faith in public life. Although Habermas’s work on religion suggests that the sacred contains important normative resources for postsecular democracies, he continues to bar explicitly religious justifications from discourse within state institutions. I question this exclusion of faith by reconstructing the role that political Catholicism played in the foundation of the European project. By focusing on two of the most important actors involved in the creation of the first European Community, French Foreign Minister Robert Schuman and German Chancellor Konrad Adenauer, I show how explicitly religious reasons can broaden political perspectives, resulting in the creation of new, inclusive, postnational forms of communal life. Pushing Habermas to accept the implications of his theological turn, I argue that pluralistic, nondogmatic and nonauthoritarian religious claims should be allowed to enter into the formal public sphere through a discursively determined interpretation of secular translation.     

Cultural rights and their contribution to sustainable development: implications for cultural policy

Abstract

This article aims to analyse the meaning and implications of cultural rights for cultural policies concerned with sustainable development. Although references to both cultural rights and sustainable development have become widespread within cultural policy documents in recent decades, the actual conceptual and operational implications often remain vague, as an ambitious discourse that may conceal a poverty of resources and capacities. As a result, the ideal horizon suggested by cultural rights and sustainable development may not always be achieved in practice, nor are the mechanisms to achieve it always well known. In this respect, the article aims to dissect the actual requirements posed by cultural rights and sustainable development, including their different notions and areas of synergy and intersections, in order to shed light on relevant cultural policy approaches. To this end, a range of examples taken from a variety of contexts will also be examined as areas of expressed needs or areas of possible solutions.
