Thermally re‐equilibrated fluid inclusions are reported in natural fissure quartz (qtz1) from polymineralic veins in the diagenetic‐anchizonal clastic sedimentary rocks of the Ciñera‐Matallana coal basin (Variscan, NW Spain). Euhedral quartz formed during early fissure opening from an immiscible fluid mixture composed of a low salinity aqueous solution and a CH4‐rich vapour phase, at temperatures of about 110–120°C and pressures ranging from 15 to 56 MPa. Five textural types of re‐equilibration are recognised in progressive order of inclusion modification: scalloped, hairy, annular‐ring shaped, haloes and decrepitation clusters. These textures resulted from a combination of brittle fracturing and dissolution and re‐precipitation of quartz, with preferential loss of water. The thermal peak was short‐lived, but was high enough to induce extensive decrepitation of fluid inclusions in vein quartz throughout the entire basin. Enhanced temperatures can be related to the intrusion of diorites in the basin. Careful analysis of textural features in fluid inclusions from diagenetic and very low‐grade metamorphism environments constitutes a useful tool for recording basin thermal history.  相似文献

As part of a research project on medieval trade and maritime transportation in the former Norwegian province of Bohuslän, western Sweden, a dendrochronological analysis of the so‐called Mollö cog was undertaken. The wreck, which was first salvaged in 1980, was previously dated by 14C analysis. Since this provided a nearly 400‐year time‐span for the building of the vessel, a more precise dating was considered essential. In conjunction with dendrochronological sampling, several features not previously reported were recorded. This paper presents the find, the research history and the results of the dendrochronological investigation. © 2012 The Authors  相似文献

The agriculture that occurs in Australia's peri‐urban regions is not well understood, nor has its economic value ever been examined systematically. Using a spatial frame derived from research into population change, Agricultural Census data are used to calculate the value of this agricultural production. The analysis suggests that peri‐urban regions in the five mainland States produce almost 25% of Australia's total gross value of agricultural production. Evidence gathered from other surveys suggests that, in some respects, this may be an underestimate. Although qualified and provisional, these findings have important strategic implications for agricultural development, urban and regional development and, ultimately, sustainable development. However, peri‐urban issues are often submerged in public policy deliberations, and peri‐urban agriculture is poorly served by the Agricultural Census.  相似文献

The relationship between cranial deformation and the occurrence of extra‐sutural bones remains poorly understood. Scholars are divided about whether or not cranial deformation causes an increased occurrence of these bones, and even those who agree that deformation does have an influence often disagree about which locations on the crania are most impacted. Part of this issue clearly stems from the difficulties in finding appropriate samples from which to test the hypothesis that deformation leads to an increased expression of extra‐sutural bones. The present study examines the effects of fronto‐occipital and occipital‐only deformation on the occurrence of extra‐sutural bones through an analysis of 59 deformed and undeformed crania from the Philippines. Relative to the undeformed crania, both deformed samples showed an elevated number of extra‐sutural bones. Using two different statistical tests, we identified a significantly higher occurrence of extra‐sutural bones at two distinct cranial localities for both the fronto‐occipitally deformed crania (coronal suture and asterion) and for those showing only occipital flattening when compared to the undeformed crania (lambdoidal and asterion). However, as our data reveal, individuals with highly elevated occurrences of extra‐sutural bones are not necessarily deformed. As such, we argue that deformation practices may have a positive impact on the formation of extra‐sutural bones; however, future studies using larger samples of deformed and undeformed crania—ideally from the same site—will be necessary to distinguish between the influence of cranial deformation on extra‐sutural bone formation relative to other population factors which may play a role in shaping variation in this feature.

Homeless people, so the story goes, are regularly excluded from spaces of consumption because they offend customers. For a significant portion of homelessness scholarship, such exclusion is the point of departure for subsequent analysis. Others, by examining homelessness within these consumption spaces, theorise that anti‐homeless policies and attitudes emerge because homeless people cannot or have not properly consumed (e.g. nice clothes, housing). This article, conversely, argues that homeless people's “offensiveness” derives from their relation to production (rather than consumption), from their class position. Homeless people's spatial incongruity, specifically, originates in their apparent unproductivity, their violation of the capitalist law of value and its ideological justifications. This historical materialist analysis is not only more revealing, it also positions homeless people as a working class faction in need of political organising rather than an abstract population in need of pitiful charity.  相似文献

Interpretive discourse analysis commonly claims to address the interrelation between actors and discourses. However, the analytical focus of most approaches is on structures (discourses) while much less attention is paid to agency. This paper explicitly addresses discursive agency in two steps. First, we systematically review theoretical and analytical dimensions of agency in existing interpretive discourse analysis approaches. This review reveals a set of shared assumptions; most notably a concept of “trialectic” agency emphasizing the constitution of agency among the individual, the (discursive) structures, and the researcher's interpretation. Second, we propose an analytical heuristic, the Discursive Agency Approach, which is developed on the basis of the review and own empirical data. The proposed approach consists of four elements: (1) policy discourses, (2) political institutions, (3) agents defined via a set of characteristics, and (4) strategic practices. This approach is meant to facilitate a systematic exploration of agency under a discourse perspective, tackling the question of how a policy is constituted through the agency ascribed to its proponents in dynamic discursive processes, and how actors acquire political relevance through discursive means. To enable this goal, we propose distinct research steps and associated methods that link the approach to existing means of analysis.  相似文献

Sound recording plays a prominent role in cultural heritage work in the Pacific region, supported by sound archives and institutional collections that serve to preserve this intangible cultural heritage. While it has long been a standard practice for field recordings to be lodged in institutions of learning, recent developments in Pacific research have emphasised the ethical and social benefits that can result from the repatriation of sound recordings to their communities of origin, and from the development of field recording practices in which cultural stakeholders are more directly involved. Meanwhile, the digitisation of historical sound recordings and the use of digital domains for dissemination have become matters of theoretical and methodological inquiry in their own right. This article seeks to contribute to the discourse surrounding the repatriation of historical field recordings through the presentation of findings from a recent Chilean government-funded digitisation and repatriation project involving previously undocumented recordings of Easter Island (Rapanui) music from the Fonck Museum, Viña del Mar. It will explain the circumstances under which the project developed, the strategies pursued in bringing it to fruition, and the reception of the project by the Rapanui community.  相似文献

Katsinam (plural of katsina) are effigies central to the religion of the Hopi people of northern Arizona in the United States. Since 2013 the Hopi have sought the return of katsinam being sold in French auction houses. The Hopi have employed a series of legal actions to stop the auctions. All such actions, however, have been consistently denied by French courts. This paper uses social science analysis to understand why the legal actions of the Hopi failed. This paper treats the case of the katsinam as a cautionary lesson in cultural heritage studies, with the goal of drawing insights that can inform other situations involving the repatriation of Indigenous cultural heritage.  相似文献

ABSTRACT My primary concern is with tracing how the police force has been transformed from a secular institution into an overtly religious one. Drawing from scholarly work on charismatic leadership and its routinization in institutional forms, much of it inspired by Max Weber's early work on these themes, my overarching aim is to grapple with the significance of Commissioner Teleni's reforms not only for the Fiji police force but more broadly for the shape of the Fijian state. While recognizing the acute importance of international relations in establishing and supporting Fiji's various political regimes, my focus here is firmly on the domain of the nation‐state as I wish to assess how politicians, military leaders, and now the Commissioner of Police attempt to constitute mass public support through their use of Christian rhetoric.  相似文献

The tradition of fastening planked boats using sewing is characteristic of the Indian Ocean region. Despite known disadvantages of sewn boats, including that perishable materials need regular maintenance and repair, operators of boats used in the sand‐mining industry of Goa still see potential in discarded sewn boats. The problems, raw materials used, technology, and process of re‐sewing and repairing these boats to give them a second life are reported and discussed here.  相似文献

This paper explores the ways in which practices of asylum governance serve to depoliticise those seeking asylum in the UK. In critiquing claims over the “post‐political” nature of contemporary governance, the paper proposes a focus upon situated practices of depoliticisation which displace those seeking asylum through the production of specific sites of accommodation and specific discourses of risk, security and moralised concern. The paper questions the tendency within “post‐political” thought to strip the potential of modes of informal citizenship through arguing that minor acts of resistance are ineffectual and illusory. In response, the paper explores irregular migrant's “acts of citizenship”, and suggests that such prosaic acts can be powerful forms of political interruption through which new ways of seeing asylum are constructed. The paper concludes by suggesting that an incremental politics orientated around such acts of interruption is essential to challenge the material, affective and discursive closures of asylum domopolitics.  相似文献

Re‐melting experiments were conducted with specimens made of high‐arsenic copper alloys containing lead, iron and sulphur. The melting treatment at 1000°C in ambient conditions for 5 min was found to cause an almost complete removal of iron and sulphur along with a notable reduction of arsenic levels. Evidence was found that the preferential oxidation of iron and arsenic was responsible for this change in composition. The treatment also brought about perfect dissolution of speiss particles scattered throughout the original specimen, suggesting the possibility of the addition of speiss to molten copper for the production of arsenical copper.  相似文献

Soils in a lower Hunter valley vineyard, New South Wales, Australia, were sampled and analysed for caesium‐137, an indicator of soil erosion status, in 1984–1985 and 2004. From the time of the vineyard's first establishment in 1971 to 1985, estimated soil losses were 250 tonnes (equivalent to 64.2 t ha?1 yr?1). Re‐sampling in 2004 showed that soil losses were 48 tonnes in the 19 years since 1985, equivalent to 9.7 t ha?1 yr?1. The decline in erosion rates may be explained by a change in land and soil management from intensive cultivation to one of no cultivation (sod culture) in 1998, and a lower annual rainfall and fewer rain‐days per year in the period from 1986 to 2004.  相似文献

The Early Bronze Age site of RJ‐2, located close to the coastal village of Ra's al‐Jinz on the eastern Omani coast (Niyabat Ra's al‐Hadd), was the focus of archaeological investigations for over two decades. The latest campaigns of excavation unearthed an architectural complex (Building XII) dated to the very end of the Umm an‐Nar period (Final UaN, c.2100–2000 BCE), previously attested on site by poorly preserved remains. This paper presents the remains explored during the most recent fieldwork, focusing on the stratigraphic‐structural sequence and the spatial layout. It also considers the transformations affecting structural evidence and material culture during this period, at both local and regional level, highlighting their significance for a comprehensive assessment of the last occupations related to the Early Bronze Age in south‐eastern Arabia. The paper concludes by showing how the Final Umm an‐Nar phase represents an age of substantial socio‐cultural innovations, which most likely shaped the transition towards the following Wadi Suq period.  相似文献

The aim of this article is to broaden the epistemological basis for investigating the current shift to cognitive‐cultural economies and the resurgence of cities and its socio‐spatial articulation. The point of departure here is that the drivers of the structural changes are indeed more or less ubiquitous, but are played out in different national institutional and urban contexts resulting in potentially diverging cognitive‐cultural economies. Four main drivers of change after 1980 are distinguished. The first is the rise of a new technological paradigm based on digital technology. The second is the thrust towards deregulation and privatization as planks of the neo‐liberal political programme. The third is the intensification of all kinds of linkages between regions across the globe. The fourth driver constitutes the processes of individualization and increasing reflexivity that have fragmented consumer markets. By identifying distinct filters which might shape and mould the impact of these more general drivers on concrete urban areas, a comprehensive framework is presented that can be used to analyse and compare the trajectories of cities while linking them to a larger narrative of societal change. A central line of reasoning is that agglomeration economies – pivotal in Allen Scott's analysis of the emergence of a cognitive‐cultural economy – are themselves embedded in concrete social and institutional contexts which impact on how they are played out. To make this point, we build upon Richard Whitley's business systems. Given this institutional diversity, we expect that various institutional contexts will generate different cognitive‐cultural economies.  相似文献

This article appraises Alice Amsden's theory of development. In particular, it focuses on Amsden's juxtaposing of the concrete and the universal, and the national and the global, as antithetical, and her prioritizing of the former over the latter. The author argues that this key feature of Amsden's work reduces the concept of development to a nationally determined process and empties capitalist development of its class content. It is argued that Amsden's primary focus on why and how development occurs in the Third World bypasses the question of what development is, thereby reinforcing ‘Third World developmentalism’, and removes the emancipatory content from the concept of development. Given the continued legacy of Amsden's theory, as evidenced in recent debates, and the inadequacy of extant Marxist critiques in addressing its conceptual and political problems, this article proposes an alternative conceptualization of concrete–general and national–global relations based on Marx's critique of political economy, and calls for the resuscitation of the emancipatory content of the concept of development.  相似文献

Abstract. This article offers a gender re‐reading of the international history of the post‐First World War peace process, a period when nationalism is said to have reached its ‘apogee’, when national self‐determination and mutual cooperation between nations in the form of a League of Nations defined liberal aspirations for a democratic new world order. It was also a period when international women's organisations emphasised female self‐determination as both a national and international issue. Juxtaposed, these two aspects of the history of the peace of 1919 shed light on the importance of sex difference to the idea of national self‐determination and to the overlapping constitution of the national and the international as spheres of political agency and influence in the early twentieth century.  相似文献
