ABSTRACT

This paper reports on results of nonlinear analyses performed within the RINTC project on an RC building isolated with different systems (High Damping Rubber Bearings, High Damping Rubber Bearings and Flat Sliding Bearings, Friction Pendulum System) and designed according to the Italian design code. The seismic response has been evaluated under different seismic input levels of two sites with different hazard and by considering two Limit States: Global Collapse and Usability-Preventing Damage. The influence of seismic stoppers and modelling uncertainties is also evaluated. Results permit to compute the implicit collapse risk and to identify critical aspects of current design procedures.  相似文献

This study offers a new framework for understanding the decision-making strategies of first-time voters. Using data from in-depth interviews with young people prior to the 2013 Australian federal election, the paper explores the extent to which our participants were knowledgeable about the upcoming election and the degree to which they invested cognitive effort into making their voting choice. The analysis reveals five distinct voting strategy typologies, which we use to construct a conceptual model that identifies and describes different voting approaches employed by young people. The findings show that young people are not a homogenous group of disinterested and disengaged voters. Instead, within a population of young citizens there are varying levels of interest and effort being invested into electoral participation.  相似文献

ABSTRACT In remote Aboriginal communities in Australia, researchers cast health beliefs and treatments as belonging to either an Aboriginal or biomedical system, which are considered to be irreconcilable and in conflict. Warlpiri people also speak of two distinct traditions that, they claim, are able to heal only specific classes of illness. Nevertheless, both Aboriginal and biomedical systems can be used simultaneously. An examination of two illness episodes will illustrate the complexity of how both Aboriginal and biomedical diagnoses and treatments are employed in a similar manner. I argue that while diagnosis is often stressed in statements regarding illness, it is only one of many factors that influence the treatment choices of individuals.  相似文献

在企业经营活动中,经济行为与伦理道德可以并存,还是难以两立,一直是学术界争议的话题。日本著名企业家稻盛和夫强调说,企业经营者必须有可以作为判断基准的哲学。坚持把“为人何谓正确”作为判断基准,不断追求正义、公正,是稻盛和夫经营哲学的核心,也是他的道德观和伦理观的充分体现。但是,做人的道德准则和企业经营的原则,特别是“利他”的道德观和企业追求利润的经营目标是否真的存在矛盾、冲突?应该如何协调、处理二者之间的关系?本文将通过对稻盛和夫经营实践中若干实例的分析,尝试对此做出回答。  相似文献

This paper presents the initial results of excavations at Kanjera South, located on the Homa Peninsula in Western Kenya. Since 1995, our exploration of this locality has yielded a combination of artefacts and well preserved faunal remains in a sedimentary context that also allows for environmental reconstruction. Here we examine the history of exploration of Kanjera and its significance in the development of palaeoanthropological research in East Africa. We also summarise our findings from the recently discovered Oldowan site. Taphonomic analyses suggest that the archaeological layers were formed at least partially by hominin activity. Artefacts made from a wide variety of raw materials are abundant, as are animal bones. Results of our first analyses confirm that Oldowan hominins had considerable behavioural flexibility and occupied a range of habitats.Cet article présente des résultats préliminaires de nos fouilles au site de Kanjera South, situé sur la péninsule de Homa au Kenya occidental. Depuis 1995 nos explorations à cette localité ont produit une combinaison des outils lithiques et des restes fossils dans un bon état de conservation venant d’un contexte sédimentaire qui permet également les reconstitutions paleoenvironnementaux. Ici nous examinons l’histoire de l’exploration de Kanjera et de son importance dans le développement de la recherche paleoanthropologique en Afrique de l’Est. Nous récapitulons également nos résultats du gisement récemment découvert d’Oldowan. L’étude taphonomique suggère que les couches archéologiques ont été formées au moins partiellement par l’activité des hominins. Les objets fabriqués faits à partir d’une grande variété de matières lithiques sont abondants, de même que les os animaux. Les résultats de nos premières analyses confirment que les hominins d’Oldowan ont eu une flexibilité de comportement considérable et ont occupé une gamme d’habitats différents.  相似文献

Joseph Parkes, Birmingham solicitor, electoral agent, whig party advisor and secretary to the Parliamentary Municipal Corporation Commission was a modern master of exposing corrupt and fraudulent electioneering and using it as a catalyst for the election of reform and Liberal politicians immediately following the 1832 Reform Act. Warwickshire's own political and legal history was the foundation for Parkes's understanding of how politics worked in Britain and what was wrong with it, and helped forge his vision for an effective reform in parliamentary and local government. This essay examines Joseph Parkes's understanding of national electoral politics, informed by his work in Warwickshire. As a local solicitor, Parkes gained the wisdom of controlling electoral registration, canvassing in a routine and orderly manner and establishing a network of professionals to secure that registrations turned into votes at elections. This experience would culminate in the formation of the Reform Club, a national organisation of whigs, Liberals and radicals, that would, eventually, become the base of the Liberal Party in modern British politics. In short, Joseph Parkes was a man who could not, and did not wish to, escape where he came from, at least in terms of his political education. His Warwickshire experiences and lessons learned, solidified a series of political reform goals that he pragmatically approached as a political advisor, operative and attorney, rather than an elected public servant, and marked the direction of politics for the rest of the century.  相似文献

Debates concerning the development of the green economy necessarily focus on “upstream” issues that underpin the re‐structuring of national and regional economies through the lenses of financial, institutional and regulatory change. However, the growing interest in the cultural green economy requires a re‐scaling of debates surrounding the links that occur in complex socio‐technical systems, notably between individual consumers, social units and the architectures of the developing green economy. This necessitates a research and policy agenda that is attentive to both the complexities of such interactions (between structures, processes and practices) and the imperative to foster change in practices within wider society. This article explores the ways in which environmental social scientists have examined and evidenced these issues, arguing that two major barriers still exist for creating adequate understandings and opportunities for change. First, the overt focus on the individual consumer as a unit of measurement and political attention has stifled debate concerning the ways in which environmentally related social practices have developed in association with wider economic contexts. In this way, environmental social scientists have often failed to make the connections between individuals, practices and the economic system. Second, in adopting a largely individualistic perspective, environmental social scientists have tended to focus their attention on incrementalist and narrowly defined views of what ecological citizenship might look like and constitute in the green economy. The article therefore argues that environmental social scientists need to constructively engage in a new inter‐disciplinary dialogue about the role, purpose and ethics of citizen participation in developing and sustaining the green economy in an age of climate change and potential resource scarcity.  相似文献

The aim of this article is to establish the extent to which the history of music can offer new perspectives on the modern period. We need a change of perspective, moving away from the aesthetic debates on music to an investigation of actual experiences and practices of participants. Audience behaviour provides a link between musical production and society. In order to make opera houses and concert halls visible as social spheres, this article draws on examples from the musical life of Berlin and London in the 1800s. Music should no longer be regarded as a peripheral phenomenon, but instead as a potential historical question. The analysis of musical performances prompts at least one: music matters.  相似文献

This paper considers the impact of distance to polling station upon electoral turnout. Using polling station level data from a London borough, it examines three types of election – parliamentary, European and local elections – over a twenty year period. The UK is notable among western liberal democracies for its relatively large turnout gap – the percentage point difference between turnout at elections for the Westminster parliament compared to that for other institutions, including local councils and the supra-national European parliament. This research considers the hypothesis that in high information, high salience elections for the national parliament the costs of voting associated with travelling to a polling station to vote in person are perceived as either low or insignificant but that in low information, low salience elections, those costs are perceived as higher and may act as a deterrent upon voting. A series of multi-level models consider the relationships between the dependent variable, percentage turnout, and a range of independent variables, including socio-economic characteristics, marginality as well as the spatial context. We show that there is indeed a relationship between distance and voter turnout, and other spatial and contextual variables, which are stronger for the lower salience European and local elections than for the higher salience national elections. Hence we conclude that the local geography of the polling station can have a significant impact on voter turnout and that there should be a more strategic approach to the siting of polling stations.  相似文献

The reconstruction of Palaeolithic subsistence and settlement systems at the Middle Palaeolithic site of Payre (France) is undertaken through the application of dental wear analyses combined to zooarchaeological, technological, and ecological indicators. Three archaeological levels were investigated. Level D, dated to MIS 5, could correspond to an occupation during the cold season. In levels G and F, dated to MIS 8-7, animals were probably hunted during a warmer season. According to dental wear analyses, it is likely that level F has actually recorded a succession of short occupations, contrary to what is observed in the levels G and D. Those differences in the duration of site occupation are discussed in the light of previous sedimentological, zooarchaeological, and technological studies.  相似文献
