At La Espiral cave, located in Bahia Honda municipality (Artemisa province, Cuba), there are several pictographs, including two of particular importance due to the design used: one of concentric circles and another of a spiral. We analyzed the pigments and binders used in one of these pictographs. The chemical ingredients of the paint are considered in this article, as well as the use of bat guano as a major pigment compound. The apparent presence of ellagic acid, ellagitannin, or anthocyanins would strengthen the hypothesis that artists used vegetable protein as a paint binder or solvent.  相似文献

The use of seashells for the decoration of pottery from the sixth millennium cal BC is well known in the western Mediterranean, with the emergence of so-called Cardial Pottery. Actually, the most discussed issue up until now has been the use of bivalves for impressed decoration. However, the experimental approach followed in the present study provides for the first time clear evidence for the utilization of a very specific group of shells as tools for the decoration of some of the early pottery productions in northwest Africa. In particular, we propose the use of cowry, a gastropod family with a well-known ideological and symbolic role in many human cultures around the world. Also, it is suggested that cowry was used for making impressed wares on the opposite European shore. The implications for reconstruction of Neolithic diffusion along both the European and African coasts of the Mediterranean are of great significance.  相似文献

Neutron activation analysis (NAA) of ceramics from Xaltocan (n?=?651) displays high values for sodium and potassium and low concentrations of many transition metals and rare earth elements compared to other sites in the Basin of Mexico. Given that Xaltocan was situated on an island in the middle of a saline lake, the potential reasons for this chemical signature are diverse. On one hand, if the sodium and potassium were elevated due to some behavioral aspect of the potters, the Xaltocan chemical groups provide a glimpse at the behaviors of Xaltocan potters that permit more precise source designations. On the other hand, if this chemical fingerprint arose due to contamination in a saline post-depositional environment, the Xaltocan chemical groups would not be valid references for provenance studies. To evaluate these alternative hypotheses, we employ several lines of evidence: (1) comparison of the Xaltocan ceramics to over 5,000 NAA assays of clays and ceramics from the Basin of Mexico, (2) experimental doping of clays with water of different salinities and fired to different temperatures, (3) leaching experiments of archaeological pottery sherds (n?=?22) recovered from the site of Xaltocan, and (4) laser ablation–inductively coupled plasma–mass spectrometry of the clay and temper fraction of a small sample of Xaltocan ceramics to determine which component is responsible for the elevated sodium and potassium values. The results suggest that the high sodium and potassium values were present in the ceramic paste before firing. We then use these newly established reference groups to better understand the role of Xaltocan in the regional economy. The type of experimentation employed in this study has proven to be an important method for determining the behaviors of ancient potters and distinguishing them from post-depositional processes.  相似文献

Here we present new excavation data from the urban site of Cerro Jazmín, Oaxaca, Mexico. Based on a comparative analysis of ceramic, faunal, botanical, and architectural evidence collected from a prominent city sector and a contemporary residence, we argue that feasting took place in the Sunken Patio Sector in the Late and Terminal Formative periods. Feasting strategies in an earlier occupation of the city sector employed a largely exclusionary strategy, giving way to a more corporate strategy in a later occupation. We take the findings from the Sunken Patio feasting complex as evidence of the formalization of Cerro Jazmin’s urban, regional role as a site of civic-ceremonial activity. Participation in this meaningful act of food consumption may have served to cement communal ties in a nascent urban society.  相似文献

This study describes a thorough inspection of a 20th century church in the town of Isla Cristina (in the province of Huelva, southwestern Spain), which is currently awaiting restoration. The study indicates the damage processes at work in the building structure materials (brick, concrete, steel, and wood), which are closely related to its geographical location, and analyses the deterioration of the wooden roof structure. The analysis of the wooden roof includes the results of an inspection methodology on a protected building based on traditional techniques such as visual inspection and innovative non-destructive inspection techniques (visual classification, ultrasounds and thermography). Fieldwork consisted of the visual classification of the wooden pieces according to Spanish standard UNE 56544:2007 specifications after which ultrasound and thermography techniques were applied on-site. A second stage involved laboratory tests (anatomic identification, density and bending strength) using wood samples extracted from the structure in order to check the values for the physical and mechanical properties previously recorded by non-destructive techniques (NDT). These non-destructive techniques are used in inspections of the wooden roofs of buildings to identify dampness, deterioration, density loss and defects as a means of assessing their conservation status. This work concludes that the use of ultrasound and thermography techniques constitute an accurate diagnostic tool for the on-site inspection of wooden structures and the evaluation of their condition. Thermography identifies different materials and moisture content while ultrasound detects the various degrees of deterioration and density-loss in areas of the wood with high moisture content.  相似文献

As well as enjoying a rich scientific history, the concept of the “city-region” has also attracted particular attention in recent years. Combinations of an urban core or cores, linked to semi-urban and rural hinterland by functional ties, are increasingly regarded as the “adequate” scale for the implementation of development policies. The popularization and widespread use of the city-region concept for policy-making has important implications for the design and implementation of development strategies. It first signals a change from sectoral to territorial approaches to development and requires the adjustment of development strategies to widely varying contexts, leading to much greater policy diversity and innovation. It also involves a more complex governance structure, characterized by the horizontal and vertical coordination of numerous institutional public and private actors, and enables experimentation with bottom-up and participatory policy-making. This paper evaluates these changes and critically addresses their normative implications, especially in light of the facts that there is still little agreement on how the city-region is defined, that the term has become appropriated by urban elites, and that the problems faced by city-regions may not be that different from those operating at other geographical scales.  相似文献

ABSTRACT

In the late seventeenth century, when Spain gradually emerged from the general crisis that had afflicted the country, several members of the cultural elite became acquainted with the new sophisticated theories and methods of modern science. This newly acquired knowledge inspired these novatores (innovators) to examine Spain’s history and historiography. They intended in the first place to integrate and align Spain with European culture at large, since the religious and ideological obstacles of the past were supposedly no longer in force. Their second purpose was to establish a scientifically based historical discourse focused on the genuine achievements of Spain over the centuries and its contribution to European civilization. They were thus willing to confront the long-standing distortions arising from propaganda, either from the outside—such as the “black legend” forged by the enemies of Spain—or from inside—such as the “fake glories” forged by earlier historians. Diverse circumstances, however, limited their enlightened endeavour, and whoever was eager to resume it in the eighteenth century came up against the restrictions imposed on modern culture by Enlightened despotism.  相似文献

Abstract

Oratorio, by Alfonso Jiménez Romero and Teatro Estudio Lebrijano, is arguably among the most representative plays of 1970s Spain’s independent theater. This play experienced many changes and adjustments before it was staged in the Festival Mondial de Théâtre de Nancy in 1971. These changes were tested in performances in Andalusia before audiences with little exposure to theater but sympathizing with the play. By studying a production that developed for three years, this article challenges the claims that support a history of theater as a catalogue of finished products. This article aims at considering the creative process that emerges from the direct contact with audiences in performing spaces. Independent theater archives have limitations, but they are made up with oral histories from troupe members. This article studies both the incorporation of theatrical devices associated with ritual participation of the audience and the use of flamenco reassessed as protest music. The latter included in the play as an artistic device since the tour in Andalusia. This play made explicit references to the Spanish Civil War, which prompted physical reactions from the audience in towns where the repression was fierce.  相似文献

ABSTRACT

A measure of health based on exact sciences is not considered by social sciences to evaluate human development. We propose the H measure of information of Shannon ([1948]. “A Mathematical Theory of Communication.” The Bell Systems Technical Journal 27 (3): 379–423, 623–656), renamed as H cto , as a general indicator of human health which can be subsequently aggregated at any statistical level. Several advantages of H cto are explained: (i) connections with thermodynamics and information theory; (ii) combination of physical and statistical elements; (iii) measurements of entropy and/or information depending on the reference point, and (iv) a collection of examples based on the scientific literature that supports the application of H cto . Simplified graphical models of the ontogeny of health condition are also shown. The empirical feasibility of using H cto is also analysed, by concluding that it could be a tangible reality in the near future.  相似文献
