Prior to industrialisation, there was a nebulous and fragmented Welsh national character or mass collective identity. Industrialisation engendered significant sociocultural upheaval and change, and for this ‘new’ society to function effectively a cohesive Welsh identity had to emerge. Because the impetus behind industrialisation had occurred primarily in a British context, any newly formed Welsh identity would ultimately have to be reconciled to the nation's industrial import within a ‘United Kingdom’. Mass cultural commonalities and the role played by leisure in this procedure is a core element in the establishment of industrial modernist nation‐states. Therefore, this article argues that public‐house culture played a central role in the construction of a new industrial Welsh national ideology that was ultimately allied to, and a constituent of, a British imperial agenda designed to exploit both the natural resources and workforce of the area to its maximum extent.  相似文献

The Kahrizak volcanic field, south Tehran, in Iran, is composed dominantly of basalt and basaltic andesite that experienced variable degrees of alteration because of the low‐grade metamorphism (stage I) and hydrothermal activity (stage II). Stage I alteration, which occurred in response to the burial of volcanic rocks and their interaction with heated groundwater, is characterized by the formation of low‐temperature zeolite facies minerals in vesicles consisting mainly of fine‐grained mafic phyllosilicate (smectite, chlorite/smectite mixed layer) and zeolites (thomsonite, chabazite, gonnardite, natrolite, analcime, heulandite, and mordenite). Stage II mineralization occurred because of the activity of hydrothermal fluids that formed large crystals of heulandite, stilbite, mesolite/scolecite, natrolite, and analcime along with quartz and calcite in cavities and fractures. The elements necessary for the formation of alteration minerals (i.e. zeolites and mafic phyllosilicates) in Kahrizak were derived from the hydrolysis of olivine and volcanic glass as well as the alteration of plagioclase. Various mineral assemblages formed during stages I and II reflect changes in temperature, pressure, and fluid composition. The change from mafic phyllosilicates to zeolites species is caused by the decrease in Mg and Fe relative to Ca fluid activities. Zeolite assemblages of stage I, known to be formed at lower temperatures, show the general sequential order from older to younger: chabazite, thomsonite, gonnardite, and natrolite. This sequence is consistent with a hypothetical fluid evolution path with increasing Na+ relative to Ca2+ activity. The change to stage II, which consists of zeolites species (stilbite, scolecite, natrolite, mesolite, analcime, and heulandite) that formed at higher temperatures, can be attributed to a temperature increase and fluid influx caused by hydrothermal activity related to a later magmatic event in the region.  相似文献

A relatively neglected area of research on agrarian and economic change is the role of indigenous concepts of labour value in the transition from subsistence to market production. In West New Britain Province, Papua New Guinea, the presence of a migrant population on an oil palm land settlement scheme (LSS) in close proximity to village‐based oil palm growers, provided an opportunity to examine changing notions of labour value through the lens of smallholder productivity. Voluntary settlers on the LSS are experiencing population pressure and are highly dependent on oil palm for their livelihoods. In contrast, customary landowners in village settings produce oil palm in a situation of relative land abundance. By examining differences in how these two groups practise and value commodity production, the paper makes four key points. First, concepts of labour value are not static and involve struggles over how labour value is defined. Second, the transition to market‐based notions of labour value can undermine labour's social value with a consequent weakening of social relationships within and between families. Third, Theories of Value developed in western contexts and used to frame development policies and projects in the developing world are often inappropriate and even harmful to the welfare of communities that have different registers of value. Fourth, in response to Point 3, and following Rigg (2007), there is a need for ‘theorising upwards’ using empirical data from the developing world to inform theory rather than applying to the developing world models of sociality and economy developed in western contexts.  相似文献

Since the late 1980s urban consolidation has become the dominant strategic planning paradigm across Australian cities; however, sites of densification are increasingly becoming sites of community resistance and conflict. In the context of the Sydney Metropolitan Strategy, this paper explores Ku‐ring‐gai in Sydney's northern suburbs as a site of community resistance centred on opposition to urban consolidation. Moving beyond more traditional constructions of community resistance as a form of NIMBYism, we present here a typology of community resistance groups and explore the complex relationships between these groups, which are used to challenge development. In addition we draw on understanding of urban publics to explore the ways in which these groups attempt to engage and act on behalf of a diverse set of publics operating across scales.  相似文献

The study of developmental abnormalities of the tarsal bones in a Portuguese Late Neolithic population was performed, as part of an ongoing research project that includes the evaluation of foot defects in Portuguese skeletal populations from Neolithic times to modern 20th century samples. Two accessory bones were found, calcaneum secundarium and os trigonum, and three non‐osseous coalitions were detected, calcaneonavicular, cuboid‐navicular and third metatarsal‐third cuneiform. The newly presented frequencies corresponded to other published sources, except for the frequency of calcaneum secundarium, higher than in previous studies (8.6% left bones; 15.2% right bones). This result suggests population homogeneity maybe due to geographic isolation and/or marriage customs although the exact pattern of inheritance of the majority of these foot anomalies is unknown. No apparent sex bias was detected and side could not be tested since these human remains were uncovered from a commingled funerary context. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

Selective mortality can occur towards individuals who survive episodes of physiological stress, such as disease and malnutrition, during development. The skeletal elements affected depend on the timing of these stressful episodes. Studying multiple non‐specific indicators of stress can show which periods of development were affected and whether certain periods can be linked with selective mortality. To examine this method a preliminary study of 61 adult individuals from the Medieval population of Fishergate House, York was undertaken to examine small vertebral neural canal size and reduced adult stature. Previous studies have shown that selective mortality occurs towards individuals who display these non‐specific indicators of stress. Statistical analysis showed that small transverse neural canal diameter was significantly associated with early adult mortality for males and females and there was evidence of selective mortality towards females with reduced stature. This suggests that individuals who died in early adulthood experienced health insults during late childhood which stunted VNC growth but males in particular were not significantly affected by health insults after this age as they achieved a normal adult stature. Therefore it appears that health insults which occurred during late childhood had a greater influence on adult health in the Fishergate House population. This method could be expanded to provide more detailed information by using a greater variety of non‐specific indicators of stress which will allow more specific periods of development to be investigated.

A total of 11 340 Cartesian coordinates of 42 homologous landmarks on five excavated human crania were recorded by three observers using a three‐dimensional (3D) digitiser and computer models created with a 3D laser scanner. The aim was to compare the errors of the coordinate data of landmarks of different types recorded with these two techniques. The results showed that digitiser‐based and 3D model‐based coordinate measurements had overall standard deviations of, respectively, ±0.79 and ±1.05 mm. However, the 3D digitiser yielded the most precise coordinate data for landmarks defined primarily by biological criteria (Type I landmarks), while the 3D laser scanner models yielded the most precise coordinate data for landmarks defined primarily by geometric criteria (Type III landmarks). These findings are likely to influence the research design of future craniometric studies, as they indicate that the suitability of certain landmark types as reference points for geometric operations, such as partial Procrustes analysis, depends on the method by which they are measured. This information is particularly important for retrospective research or for combined databases such as FORDISC or CRANID, which may integrate different types of landmarks recorded by different researchers and/or instruments. Crania displaying poor preservation and surface discoloration yielded larger measurement errors, especially for the 3D model measurements. This is not surprising given that landmarks on 3D models cannot be located using tactile means, but have to be located solely on a visual basis. Nonetheless, even though the digitiser measurements exhibit an overall precision slightly greater than the 3D model measurements, both techniques yield coordinate data with a precision sufficient for most craniometric research.

Ochres were the most common source materials for pigments used in Palaeolithic rock art paintings. This work analyses the petrographic and geochemical signatures of different ochre samples from outcrops inside Tito Bustillo Cave and the Monte Castillo Caves using the most common techniques (petrography, XRD, SEM–EDS and ICP–MS) in archaeological pigment characterization studies. The results obtained permit the identification and characterization of the different source ochre types and, furthermore, allow the establishment of mineralogical and geochemical proxies for the study of questions related to ochre characterization, formation processes and provenance.  相似文献

The Pichvnari necropolis on the Black Sea coast of Georgia lies in an area known in the late first millennium as ‘Colchis’, on part of the trade route leading to the Orient. The burials of the necropolis date to the late fifth century bc and frequently contain grave goods, including extremely well‐preserved polychrome glass beads and core‐formed vessels. This paper presents a study of these vessels both stylistically and archaeologically and using SEM–WDS and LA–ICPMS. It reveals that the vessels have compositional differences that may point to multiple manufacturing sites. One of the vessels appears stylistically unique and may exhibit one of the earliest uses of manganese as a decolorizer. Major and minor element data for the vessels suggest that they may belong to the same ‘Levantine’ group as many Roman glass objects, suggesting that a source of sand on the coast of the Levant could have been used in their production. The beads clearly show glass with both natron‐ and plant ash‐based flux with distinct rare earth compositions, showing multiple sites of production, some of which were probably either in the Middle East or the Indian subcontinent.  相似文献

This paper is concerned with the manufacture and trade of post‐medieval crucibles (14th–19th centuries). The analytical study of crucibles from different contexts in Europe and America employed optical microscopy and SEM–EDS, coupled with archaeological and historical data. We identified two major producers of crucibles, both of them in Central Europe, whose products appear widely distributed internationally. The analytical data allow an explanation of the technical reasons behind their superior reputation, as both crucible types shared comparable material properties, such as thermal, chemical and mechanical stability. Conversely, the two crucible types were radically different in their manufacture and appearance. We argue that, besides technical considerations, sensorial aspects such as texture and colour may have played an important role in the perception and choice of materials.  相似文献
