Qadhat is the name for a lime mortar in Southern Arabia. Its usage has a long tradition. This work describes physical and
mineralogical properties of ancient, historical and new samples, which seem to have been produced the same way. XRD, thin
sections and SEM analyses show the similarity of the material. It consists of aggregates of volcanic material that are rich
in volcanic glass and lime as binder. The production process includes several hours of crushing the material, which produces
fine-grained splinters of aggregates in the binder matrix and gives the mortar a high stability. A weathering test with sodium
sulphate on different samples confirms that the stability of this mortar is the result of the production process. 相似文献
The western region of São Paulo state, Brazil, became one of several sites of global cotton production during the first half of the twentieth century in response to increased global demand and fears of cotton shortages. The cotton boom tapped a ‘forest rent’ that helped Brazil rise to become the largest producer in Latin America, providing both export revenue and critical raw material to a growing industrial economy that would become the largest in South America. This paper uses an organizational and institutional perspective to analyze causes and effects of the mid-century cotton boom that centered on São Paulo state. Organizations and institutions relating to cotton production are considered using oral histories, judicial documents, agronomic texts, and the sediment record in small catchments as empirical evidence. The state dramatically reformed some organizations to provide the key inputs to cotton production, while most contemporary observers ignored institutions, such as sharecropping and tenant farming, that supported cotton. São Paulo's institutions and organizations were characterized by the borrowing and adaptation of existing labor institutions, the creation of new state organizations that subsidized elite producers, and the weak development of institutions or organizations in response to soil fertility issues and labor supply. 相似文献
The Corded Ware is one of the major archaeological traditions of Late Neolithic Europe. Its burial customs are characterized by single graves but multiple burials also occur. We present a detailed study of antemortem and perimortem trauma in a group of Corded Ware skeletons from four multiple graves and give the most probable interpretation of the site, based upon all available bioarchaeological evidence. The pattern of observed injuries in male, female, and subadult skeletons, including cranial trauma, arrow wounds, and fractures of the forearm and hands points towards a violent event that resulted in the death of all individuals, most probably a raid. In contrast to comparable Neolithic raid sites, there was no complete extermination of the local population and no use of mass graves. The burials have been arranged with care and detailed knowledge about biological kinship ties [Haak, W., Brandt, G., de Jong, H.N., Meyer, C., Ganslmeier, R., Heyd, V., Hawkesworth, C., Pike, A.W.G., Meller, H., Alt, K.W., 2008. Ancient DNA, strontium isotopes, and osteological analyses shed light on social and kinship organization of the Later Stone Age. Proceedings of the National Academy of Sciences of the United States of America 105, 18226–18231]. The combination of clear causes of death and the proven biological relationships among some of the individuals, including a nuclear family, provides new and important insights into Corded Ware mortuary customs and the reasons why and how multiple graves have been utilised. 相似文献
The Central Anatolian Volcanic Province (CAVP) in Turkey preserves widespread deposits of Quaternary tephra, presently associated with a small but growing number of Paleolithic archaeological sites. We use multivariate analyses of the abundances of a suite of nine major and minor element oxides determined by electron probe microanalysis. From these data, we construct a classificatory model for correlating distal tephra to one of five volcanic edifices or eruptive phases within the CAVP. Application of this model to distal deposits of primary tephra-fall and reworked tuffaceous sediments from the archaeological sites of Körkuyu and Kaletepe Deresi 3 indicates Late to possibly Early Pleistocene ages for the artifact assemblages there, and provides a fundamental tephrostratigraphic framework to examine spatial and temporal variation in hominin behavior comparable to that of other regions, such as eastern Africa. 相似文献
Territoriality is mostly discussed as the political competence to exert control on a certain space, in particular with regard to the nation state. Globalization and European Integration have initiated some debate on this understanding, but cross-cross-border cooperation has rarely been linked to this debate. In these areas enormous political changes have been seen during the recent years. Still, the territorial dimension cannot be addressed, as territoriality as known from nation states is challenging politics. However, the territorial implications are manifold and are increasing throughout Europe. Against this backdrop is conceptual reflection. This paper starts with a brief overview of discussions and the empirical implementation of the territoriality debate. Based on this, the paper attempts to catch up with the political changes – the reflection of cross-border territorialities in a two-fold way. The purpose of this paper is to contribute to this field.
First, we propose a methodological approach to study the essential aspects. We study from a conceptual point of view, the dimensions of territoriality in cross-border contexts. These are explored as well as the political-juridical background of cross-border cooperation. Based on this, a C-B-IM-tool (Cross-Border Institutional Mapping) has been introduced, involving three steps: (a) (a1) multi-level mapping of cross-border institutions, (b) (a2) mapping of policy arenas and (c) (a3) mapping of the political topography in the sense of going beyond formalized and codified governance patterns. Secondly, with the example of the Greater Region around Luxembourg, the empirical and conceptual findings on cross-border territoriality are illustrated. We can state an establishing cross-border territoriality that does not replace domestic, state-centric territorialities but that inserts new and complex elements of a multi-level territoriality system. 相似文献
During the three-month long Sino-Japanese hostilities in the summer of 1937, Shanghai industries suffered the heaviest loss ever sustained during any previous military conflict in the city. Yet as has been shown in a previous study, local industries seem to have recovered fairly quickly. All statistics point to a return to pre-war levels of production in most sectors by the end of 1938 in some cases and during 1939 for most industrial branches. The purpose of this paper is to try to highlight the spatial dynamics at work in this recovery process. It relies not just on original sources, but on the unique capabilities GIS offers in processing large amounts of historical data and exploring connected issues in land use, demography, and urban life. The paper argues that Shanghai industries went through a thorough phase of relocation and migration within the city, but also of inbound migration from the surrounding regions. This study is based on a particular set of documents produced by the Shanghai Municipal Council, the largely independent body that administered the International Settlement. In this study, therefore, I shall argue that what happened in the territory of the International Settlement mirrored what happened next door and possibly in other parts of the Chinese-administered/Japanese-occupied areas. Beyond the issue of industrial movement, this paper also examines connected issues in land use, demography, and urban life. 相似文献
