One hundred and eleven samples from the important Servilia Roman tomb have been analysed for the first time by Raman spectroscopy, resulting in a complete characterisation of the pigment palette used for its remarkable wall paintings: 73 different pigment mixtures have been identified for the composition of its 11 colours and their tonalities. Dyer’s weld, an ancient organic yellow pigment, which was described by Vitruvius, has been identified and characterised for the first time in Roman wall paintings. Distinctive Raman spectroscopic signals which differentiate between haematite and caput mortuum (a violet colour from haematite which has been subjected to thermal treatment) are also reported. The use of the very expensive lazurite for a balance relates the importance of this otherwise ordinary instrument with psychostasia (the human soul weighing process) and is not found elsewhere in the tomb. The distribution of white minerals alone or in admixture is not related to any particular colouring pigment or figure; this possibly indicates that there was no specific use for each white mineral and that several craftsmen worked on the paintings, perhaps in different periods, or that the frescoes have been subjected to unrecorded restoration. We conclude that Raman spectroscopy is a valuable analytical technique for the unambiguous identification of mixtures of both organic and inorganic compounds, to study the degree of mineral crystallinity and for identifying treatment. These data are relevant for the holistic interpretation of the artwork in its historical, economical and social context.  相似文献

In this study, we aim at evaluating the role of path-dependent and past-dependent forces in the historical trajectory of clusters. For that purpose, we study the life cycles of four of the main industrial clusters in the Basque Country (paper-making, electronics and information and communication technology, maritime industries and aeronautics) and analyse the factors that account for the origin, development, maturity and, if so, decline of those clusters, considering factors related to both cluster dynamics and the regional environment. Our analysis shows that the existence of a life cycle does not imply a straightforward growth path. Clusters follow multiple growth patterns in their development. The heterogeneity of growth patterns may be, in some cases, due to different initial conditions. However, despite similar initial conditions and/or resource endowments and opportunities for development, we can observe heterogeneous evolutionary patterns. Clusters react differently to the same external shocks (e.g. international demand, global competition and technological change) and evolve differently according to their capabilities.  相似文献

This paper analyzes the influence the Chemical Institute of Sarrià (IQS) ‐a private institution devoted both to the education of chemists and chemical engineers and to applied research‐ has had on Spain's chemical industry from 1916 onwards. The research reported is based upon three data sources (articles on industrial chemistry published by the IQS’ journal Afinidad and M. Se. theses; IQS graduates’ industrial activities; and technical services carried out by the Institute's staff for several companies). The main conclusion is that the IQS has had a remarkable impact on Catalan and Spanish industry. Although there are no other similar studies on Spanish scientific and technical institutions, the IQS case confirms that technical education and institutionalized research have a positive impact on the economic and industrial development of “latecomers” like Spain.  相似文献

Previous research acknowledges the ancient and complex land-use history of European mountainous areas, which are characterised by a remarkable regional variability in terms of human practices and patterns of occupation during the Holocene. However, the combined palaeoenvironmental and archaeological study of highland human management at a micro-regional scale remains a largely unexplored research field, especially in the Pyrenees. A combined pollen, stomata, non-pollen palynomorphs (NPPs) and macrocharcoal study was carried out at three nearby alpine and subalpine peat basins from a relatively small territory (ca.1700 ha) at the Madriu valley (Andorra, eastern Pyrenees), following a fine spatial-resolution strategy. The purpose was to test the suitability of high altitudinal palaeoecological sequences when reconstructing past small-scale land-use variability. The palaeoecological results of those peat records are compared and further integrated with archaeological local data, and together underline the marked complexity of high mountain land-use system over the Holocene period. Main phases of micro-regional land-use and landscape variability can be distinguished from the middle Neolithic to the early Bronze Age and from the Roman Period to the Modern Era. Conversely, several phases of homogeneous landscape management are distinguishable during the early Neolithic, and from the late Bronze to the late Iron Age. Results drawn from this study show that landscape variability is not necessarily connected to topographic or climatic parameters, and underline the role of social, economical and cultural parameters in the land-use organisation and the landscape shaping of high mountain spaces since Prehistory.  相似文献

In the present study a simple method is described for obtaining 3D digital models of petroglyphs of different sizes and characteristics and its usefulness, in the study of this cultural heritage, is evaluated. For this research we used low-cost photogrammetric software and consumer-grade digital cameras, without any other surveying techniques. In order to test this methodology, three field research studies were carried out in Galicia (Spain).  相似文献

This article examines the borderlands between transgender MTF (male‐to‐female) and gay male communities in Latina/o Miami through an analysis of the participation of Latinas in the Transsexual Action Organization (TAO). Previous research suggests that Cuban and Cuban American gay male culture have historically been associated with gender transgressive behaviour and identity. Because of this, it is often unclear how to distinguish between what is gay male/homosexual expression and transgender expression. If outward gender manifestations that we now call ‘transgender’ were understood in other historical and cultural contexts as ‘homosexual’, how do we label those manifestations today? By labelling them as homosexual are we simply reinscribing the marginalisation of transgender individuals? On the other hand, by labelling them as transgender are we imposing a contemporary category and therefore performing another kind of intellectual violence? In order to address these questions, I analyse a Latino/a organisation that explicitly labelled itself ‘transsexual’. TAO was an early transsexual rights organisation founded in 1970 by Angela Douglas in Los Angeles which moved to Miami Beach, Florida in 1972. Drawing on the organisation's publications, Moonshadow and Mirage Magazine (1972–75), and Douglas's self‐published autobiographical texts, Triple Jeopardy: The Autobiography of Angela Lynn Douglas (1983) and Hollywood's Obsession (1992), I analyse the rarely discussed participation of Latinas in the organisation.  相似文献

The aim of this paper is to explain the subsistence strategies of late hunter–gatherers from the Northeast of the Iberian Peninsula on the basis of zooarchaeological and archaeobotanical records. The study is based on the Molí del Salt archaeological site which has yielded an Upper Palaeolithic and Mesolithic sequence. Each of the disciplines shows us a various type of assemblage to approach the same problem. Archaeobotanical materials, including charcoal and seeds provide data on the strategies related to firewood gathering and vegetal food supply, which was a basic subsistence resource for these groups. The archaeobotanical assemblage is mainly formed by conifers, but other species related to edible plants are also important. Bone assemblage, mainly formed by Oryctolagus cuniculus, show how hunting and meat processing is highly related. The environmental constraints as well as mobility are discussed in order to achieve an ampler knowledge on human activities.  相似文献

The paper presents the results of interdisciplinary (multiproxy) palaeoenvironmental studies of peat — calcareous tufa depositional sequences of spring mire from Radzików site (east Poland). Analyses of three biotic proxies (plant macrofossils, pollen, molluscs) were supplemented with sedimentological, geochemical, oxygen and carbon stable isotopes analyses and radiocarbon dating and used for reconstruction of environmental changes in Late Glacial and Holocene. The obtained results enable us to (1) reconstruct main phases of mire development and (2) determine environmental factors influencing changes of water supply.  相似文献
