The second half of the 19th century, along with the first three decades of the 20th, saw the building of hundreds of flour mills in Spain, all based on new milling and sieving machinery developed after the industrial revolution. Unfortunately, very few of these early mills are now in use: most have disappeared, and many of those that are left have been abandoned. The present work examines the growth of the flour-milling industry in Spain from the mid-19th century, and discusses the typology, design and constructional features of its associated buildings. The information presented is the result of the study of a representative sample of these mills in central Spain, and could serve as a basis for the conservation, rehabilitation and reuse of this important agroindustrial heritage.  相似文献

Determination of the source of Spondylus objects is essential for the interpretation of Late Neolithic exchange systems and the social role of shell ornaments. We performed stable isotope analysis combined with cathodoluminescence microscopy study on ornaments (beads, bracelets) made of Spondylus shells excavated at the Aszód-Papi földek archaeological site in Hungary, to define their origin. For comparison Spondylus finds from Neolithic sites of Greece, modern Spondylus shells from the Aegean and the Adriatic, as well as fossil Spondylus and Ostrea shells from the Carpathian Basin were also examined. Oxygen isotope composition of Spondylus finds from Aszód ranges between ?1.9 and 2.1‰ and overlaps with the oxygen isotope range of shell objects from other Neolithic sites. Modern Spondylus shells from the Aegean and the Adriatic show overlapping δ18O values with one another and with the Neolithic objects; while recent shells of the Black Sea clearly are separate isotopically from the Mediterranean ones and most of archaeological artefacts. Spondylus shells from the Aszód site have Mediterranean origin; their source can be the Aegean or the Adriatic. Based on a former strontium isotope study the use of fossil Spondylus shells is excluded as raw material used for ornaments, however, in recent years the use of fossil shells was reintroduced. The shell ornaments from Aszód-Papi földek and the fossil oyster shells collected from the Carpathian Basin exhibit some overlapping oxygen isotope values; however, cathodoluminescence microscopy indicates that the Spondylus objects retained their original aragonite material. Diagenetic calcite, which occurs typically in the fossil shells, was not detected in the ornaments suggesting that the studied objects were made of recent shells. Calcitic parts observed in some Spondylus objects are not related to fossilisation.  相似文献

The implementation of a 3D Electrical Resistivity Tomography (ERT-3D) survey was carried out in El Pahñú archaeological site, Hidalgo State, Central Mexico. A combination of a new ERT arrays allowed studying the subsoil beneath the Main Pyramid built near the edge of a plateau, along with another important structure (the Tecpan), which was a smaller structure that lodged the governmental council in pre-Hispanic times. The recorded information was acquired through the combination of several electrodic designs: L-Corner (LC), Equatorial (Eq), and Minimum Coupling (MC). For the Main Pyramid, the electrodes were set up around the perimeter of the structure, since they were not permitted to be inserted over the edifice, thus preventing damages to the architectonic elements. The second structure allowed inserting electrodes on selected spots within the architectonic space. The combination of the different arrays made possible the acquisition of 1204 apparent resistivities beneath the Main Pyramid and 2460 resistivity data beneath the Tecpan. The apparent resistivity data were inverted to obtain a three dimensional display of the subsoil electrical resistivity beneath the archaeological structure. The interpreted resistivity model under the Main Pyramid displayed a highly resistive structure towards its northern face that could be associated with infill. Such material was employed by the ancient constructors to level the terrain close to the edge of the cliff. Another interesting anomaly was found towards the central portion of the structure that could be associated to a foundation offer. The interpretation of data beneath the Tecpan identified the structural foundations and other interesting anomalies related to the different occupational times. The investigation supported the archaeological investigation of the site, suggesting areas of potential geological risk and of archaeological interest. For example, the Main Pyramid presents serious stability problems, indicating that the infill has weakened, producing cracks threatening long-term pyramid integrity.  相似文献

This article reflects upon the methodological challenges posed by the study of secretive organizations and programmes. In particular, it examines the question: when participant‐observation is not a feasible option, what techniques can anthropologists use to shed light upon covert military and intelligence agencies and the corporations that they contract? After reviewing anthropological research on secret societies from the late 18th and early 19th century, the author turns to contemporary anthropological work on bureaucratic institutions and initiatives that operate in secret. The author's own research into the US Army's Human Terrain System serves as an illustration. By adapting Laura Nader's suggestions for ‘studying up, down, and sideways’, the article suggests that documentary analysis (of both openly accessible and classified documents), interviews, and ‘self‐analysis’ provide a fruitful combination of methods for an anthropology of the covert.  相似文献

The purpose of this paper is to discuss the theoretical genealogy and main uses of heritage in actually existing communist countries. This is performed by carrying out a critical review of Èleazar Aleksandrovi? Baller’s Communism and Cultural Heritage, (1984, Progress, Moscow). The analysis of Baller’s work reveals that the logics of heritage in communist countries differed in various ways from capitalist countries, mainly because of the almost total state control over the heritage apparatus and the subordination of heritage policies to Marxist–Leninist ideology. Heritage was fundamental in dealing with the problem of change and continuity with the traditions, narratives and identities of previous society, and in the process of transforming citizens into ‘new men’ through the cultural revolution and the inculcation of ideology through museums and monuments.  相似文献

The foundation of the modern Ecuadorian State in the 1940s and early 1950s coincides with a series of attempts to synchronize and incorporate certain “problematic” sectors of the population that were supposedly resistant to progress and whose forms of life were incompatible with modernity, a capitalist economy, and a cohesive nation. This biopolitical project for the modernization and governance of the population also had repercussions on—and analogous manifestations within—the discourse of national identity, the design of cultural policies, and the production of State-sponsored national art. This article analyzes Huacayñán / El camino del llanto / The Way of Tears (1952–1953), a collection of FIGURE 3 aintings by Oswaldo Guayasamín that was commissioned by the government of Ecuador in 1951. Huacayñán was conceived within the ideology of mestizaje as an instrument of aesthetic cultural modernization and as a visual artistic showcase of the harmonious integration of ‘Ecuadorians.’ Despite, or even because of its governmental overdetermination, however, this article shows how Huacayñán instead materialized the exclusionary logic of the syncretic and biopolitical policies of the State, displaying dystopic visions of violence and exclusion, and of a fractured nation inhabited by monsters and resistant to mestizo-ization.  相似文献
