This study presents the results of the static and dynamic assessment of the dome of the Basilica of Santa Maria degli Angeli in Assisi, designed by Galeazzo Alessi. The first section is devoted to an overview of the masonry domes designed by the Italian architect and focuses on the structural solutions adopted in the several cases described to better understand Alessi’s designing skills. In the second part, the drum-dome system is analyzed in order to attain a structural assessment. The static assessment is performed by means of limit analysis and finite element model approaches with non-linear mechanical behavior. The obtained results are consistent with the detected crack pattern and confirm the suitability of the reinforcement steel rings applied to the drum. The seismic assessment has been performed by response spectrum analysis. Due to the lack of specific information, a probabilistic approach for the material mechanical properties was used. The results obtained highlight an adequate seismic response of the structure that can be attributed to the dynamic properties of the slender drum-dome system. This finding justifies the good performance of the structure during the seismic events of 1832 and 1997.  相似文献

This case study of fatherhood in early nineteenth-century England examines the conflict between a wealthy East India Company merchant and his increasingly wayward adolescent son, who was transported to Australia in 1814. It argues that fatherhood was often necessarily a reactionary process, that did not conform to a static, historically specific model of ideal or dysfunctional fatherhood. It also traces the origins of much of the disagreement to conflicting ideals of masculinity between father and son, which were exacerbated by their rise in wealth and social status. Since both aspired to the elite status of gentleman, the article demonstrates that competing and compatible ideals can co-exist within different generations of the same family. Thus a study of male family experience suggests that hegemonic masculinity is subject to short-term shifts of emphasis on those values adopted by men of different ages and social status.  相似文献

This article examines evidence of self‐determination and independent action in the practice, among a significant group of late medieval English women, of donating their own clothing and household linens to parish churches for use in sacred ritual.
The argument is presented that clothworking in a domestic environment was a highly valorised activity closely connected with women, for which the spindle and distaff acted as an index, and that against this background women used textiles as a site for expressing their personal, social and religious concerns.  相似文献

Since 1999, there has been much debate within the international community on what the future status of the autonomous province of Kosovo should be. However, there seems to have been little consideration as to why the Ottoman vilayet of Kosovo and the other majority Albanian-speaking areas (now parts of Montenegro, western Macedonia and north-western Greece) did not become either independent or part of an independent Albanian state, despite the legacy of these decisions. Focussing on British policy and perceptions, this article explores the role of the great powers in the delimitation of Albanian boundaries, particularly in two boundary commissions in 1913 and 1914: one determining the southern Albanian boundary with Greece and the other concerning the northern and north-eastern boundary with Serbia and Montenegro. The first part of the article considers the influences and interactions of two sets of factors in the boundary deliberations: the declared rationale of creating nation-states in south-eastern Europe based upon ethnographic criteria (linguistic boundaries) and the competing role of geopolitical interests in their decision-making, focussing particularly upon British interests. It illustrates that the decisions made to delimit the newly independent Albanian state primarily reflected the resulting great power conflicts and compensations, rather than the professed ethnographic rationale. The second part of the article explores some of the consequences of the decisions made to delimit Albanian boundaries, especially in ‘ethnic’ or national terms.  相似文献

Abstract: Families, the state and employers all have a broad if differentiated interest in securing the daily and generational reproduction of society. Whereas in Western countries, the past two decades have witnessed a progressive displacement of responsibility for social reproduction from the state to families, in southern Africa, day‐to‐day social reproduction has always remained overwhelmingly the preserve of families. Today, however, the AIDS pandemic is radically transforming family life for many children, and prompting concerns (arguably a moral panic) about the potential breakdown of social reproduction. Even in Africa, schools have long supplemented families in delivering generational reproduction, albeit geared around the transfer of “factual” knowledge and with a narrow focus on preparing new generations of workers. In light of the AIDS pandemic, a number of commentators have suggested ways in which schools could further substitute for the diminishing capacities of families. Based on interviews with decision‐makers and analysis of policy documents, I explore a number of interventions being enacted in Lesotho's schools. I argue that such initiatives remain small in scale and often justified in relation to retaining children in school. In practice both government and employers remain more interested in the generational reproduction of workers than in daily reproduction. If the welfare needs of AIDS‐affected children are to be met through schooling, there is a need for the education sector's role to be understood in relation to an ethics of care, rather than the functionalist production of a future workforce.  相似文献

The Middle Ages have been traditionally considered a crisis period due to the demographic decrease and economic deterioration occurred in Western Europe. Nevertheless, the historical reconsideration has been focused not only on decline and decay, but also on resilience and recovery which characterized the Europe of the fourteenth and fifteenth centuries. So, today the main open question is as follows: how can we explain the diverse attitude (namely recovery versus decline) and the reasons why some settlements were more (or less) resilient than others? To provide a contribution to this issue, we focused on two medieval villages which are located very close to each other (in the Basilicata Region Southern Italy) and selected because they are characterized by diverse vicissitudes: Irsi abandoned in the fourteenth century and Montepeloso (still “existing” and renamed Irsina) where the population of Irsi moved to. To improve our current knowledge on Irsi, we reused and integrated multiscale LiDAR datasets in order to cope with the lack of documentary source. The use of LiDAR data enabled (i) the reconstruction of the potential urban fabric of Irsi, along with its temporal development and the transformation of the surrounding landscape, and (ii) the definition of a hypothesis about the causes of its desertification based on the inter-site analysis between Irsi and Montepeloso. The main results from the LiDAR-based analysis were as follows: (i) the diachronic reconstruction of the building phases of the village and (ii) the identification of a significant indicator obtained as the ratio between the amount of cultivatable land (close to the settlement area) and the population to characterize the resilience behavior in hilly landscape. This approach has been also successfully applied to another similar case study. Outputs from our analyses pointed out that LiDAR data can fruitfully improve medieval archaeological investigations and facilitate knowledge improvement from intra to- inter-site scale analyses and from local up to a landscape perspective.

Research in Bangladesh reveals the limitations of actor‐oriented frameworks for understanding urban poverty that assess household livelihoods on the basis of a household's portfolio of assets or capitals. The narrow focus of these frameworks on households and their depoliticized definition of social capital overlook the political roots of urban poverty. The informal systems of governance that dominate resource distribution within low‐income settlements ensure that the social resources necessary for long‐term household improvement are confined to a small elite. Only through extending our analysis beyond the household level, to explore their position within this local political economy of employment and enterprise, can we recognize the limitations placed on household efforts to improve their livelihoods.  相似文献

ABSTRACT

This work investigates the use of an advanced long-term vibration-based structural health monitoring tool to automatically detect earthquake-induced damages in heritage structures. Damage produced in a monumental bell-tower at increasing values of the Peak Ground Acceleration (PGA) of the seismic input is predicted by incremental nonlinear dynamic analysis, using a Finite Element model calibrated on the basis of experimentally identified natural modes. Then, predicted damage effects are artificially introduced in the monitoring data to check for their detectability. The results demonstrate that a very small damage, associated to a low intensity and low return period earthquake, is clearly detected by the monitoring system.  相似文献

In February 2007, UNICEF launched the latest in a series of reports comparing the conditions of young people's lives across the world's more industrialised countries. The report ranked the UK as the lowest of the countries investigated. We give a critical overview of the report, identifying its limitations as well as some of the trends it reveals. We also discuss the poor placing of the UK in relation to current broader political and public debates.  相似文献
