In recent decades, there has been a noticeable increase in the use of quantitative techniques in the study of ethnicity and nationalism, without, however, a sufficient amount of reflection on how these techniques have contributed to our understanding of ethnic and national identities. As such, in this exchange three sets of authors answer questions about the degree to which it is possible to use quantitative data to measure ethnic and national identities, which types of methods are most suitable in measuring these identities and what the major research findings of this quantitative research are that were not possible using qualitative approaches.  相似文献

We present a new curve of the directional secular variation of the geomagnetic field in Western Europe between 1500 bce and 200 ce . Its computation relies on a Bayesian framework. The fast secular variation during the Late Bronze and Early Iron Ages makes archaeomagnetic dating efficient with a respective precision of 150–200 and 60–100 years during these periods. The Bayesian method also provides posterior date distributions that refine the dating of reference data, especially during the period of the Hallstattian radiocarbon plateau. Archaeomagnetism becomes a valuable alternative to radiocarbon and will help to improve the archaeological chronologies.  相似文献

There has been a recent increase in the body of knowledge related to children and disasters. These studies converge into three main fields of research: the impact of disasters on children and their psychological recovery, the integration of disaster risk reduction (DRR) into the education sectors and children’s participation in DRR. This article provides a literature review of the two latter fields of research where the focus is on reducing disaster losses and building resilience prior to a disaster. Overall, 48 studies are critically reviewed and compared in relation to the strengths and weaknesses of their aims, methods, locations of research, impact, and outcomes. The review identified a number of differences between the two fields and significant opportunities for linking the two approaches, sharing lessons and knowledge. Based on the review, recommendations for further research are outlined.  相似文献

The Early Bronze Age was a time of major changes in southern Levantine regions. The spread of urbanisation in the course of the third millennium BC was accompanied by various socio-political transformations, tensions and also violent encounters, even if the evidence for the latter is hard to detect in the archaeological record. The almost complete absence of arrowheads from settlements and tombs in the southern Levant from this period has led to the assumption that combat archery was not employed during the Early Bronze Age.

This paper challenges this orthodoxy using evidence from the southern Levant and beyond, and it concludes that archery was employed in combat activities during the Early Bronze Age, albeit on a small scale that was determined by military considerations.  相似文献

Urban commons are characterised in the literature as collectively shared property in the city shaped by a context of scarce resources, population density, and the interaction of strangers. In the broader commons literature, commons appears as a verb, a noun, and a process made by practices of commoning—albeit still with a focus on property. In this paper, I argue that an understanding of urban commons as more‐than‐property is needed to recognise how present but elusive urban commons are. I use examples from interviews and observations conducted at a Women's Library to discuss how the access, use, benefit, care, responsibility, and ownership of this urban commons bring it into being through particular practices of commoning. By questioning current ways of defining urban commons, urban scholars gain a grounded understanding of the role of property, and other practices, in maintaining an urban commons over time.  相似文献

In this study a structural investigation on the ogival masonry domes is performed with particular attention to the significant debate between mathematicians and architects mainly of the French and Italian schools that characterized the 18th century. In this period, analytical approaches to investigate the static of dome structures were developed concurrently for the affirmation of the proportional methods, as reported in several architectural treatises in which graphical constructions for the design of masonry domes can be found. It is well known that Carlo Fontana, in 1694, was the first to show in detail the geometrical rules for the design of a masonry dome. Later, in 1760, the Italian architect Bernardo Antonio Vittone proposed some variations to the rules written by Fontana in order to increase the height of the dome and the slope of the meridian section at the intersection with the lantern. In this study, Vittone’s dome has been analyzed and compared with Fontana’s dome by means of an analytical approach that also considers the influence of the lantern at the top. The obtained results confirm that Vittone’s rules lead not only to architectural, but also structural improvements.  相似文献

In this paper I argue that imbalances and silences persist in urban research. In particular, there is insufficient attention to anti‐racist and feminist theoretical, methodological, and empirical insights. Intersectional and materialist urban analyses that take difference seriously are under‐represented, while patriarchy, privilege, and positivism still linger. As a partial and aspirational remedy, I propose a “Feminist Partial Political Economy of Place” (FPEP) approach to urban research. FPEP is characterized by: (1) attention to gendered, raced, and intersectional power relations, including affinities and alliances; (2) reliance on partial, place‐based, materialist research that attends to power in knowledge production; (3) emphasis on feminist concepts of relationality to examine connections among sites, scales, and subjects, and to emphasize “life” and possibility; and (4) the use of theoretical toolkits to observe, interpret and challenge material‐discursive power relations. My own critique and research centers on North American cities, but FPEP approaches might help produce more robust, inclusive, and explanatory urban research in varied geographic contexts.  相似文献

Aerial photography provides a valuable recording method for archaeological sites and is often underutilized. In the past, aerial photographic platforms were expensive and often required highly specialized equipment. However, with new technology a variety of different platforms are now available. This paper will analyze two low cost aerial photographic platforms used at the Australian Archaeological Institute at Athens/University of Sydney's project at Zagora, on the island of Andros, Greece. Over two years, both kites and drones were used with relative success. Through a review of the application of both systems on the project, along with a quantitative analysis of the cost, transportability, operation and quality of photographs, the strengths and weaknesses of both platforms will be discussed.  相似文献
