Critics have been uncertain as to the genre of Catalan writer Jaume Cabré's 2000 book, Viatge d’hivern. The confusion, I argue, is due to the fact that the volume is a short story cycle, a literary form situated midway between the novel and the short story collection. Forrest Ingram differentiates among composed, arranged, and completed cycles, and Cabré's comments in his Epilogue to Viatge d’hivern indicate that the book is an example of the third category. While he composed its fourteen narratives over a period of years, when he revised them for inclusion in a single volume he discovered that various threads, some secret and others more obvious, connected the stories. In this essay I examine ways in which theme, structure, and motifs, as well as recurrent imagery and wording, form a web of associations among the individual units of Viatge d’hivern.  相似文献

Theatrical stages have long been home to performances of identity, creating and sustaining legible visions of various peoples and groups for their audiences. Indeed, in the nineteenth century, the playwright/actor Dion Boucicault popularised the “stage Irishman” for Irish and American audiences alike, thus contributing to the invention of “Irish-America”. This paper examines a similar attempt in the late twentieth and early twenty-first centuries to query the definition of a distinct group of Irish-Americans: the Scots-Irish. Productions from Belfast, Northern Ireland, as well as from the southern Appalachian Mountains, demonstrate how the illegibility of the Scots-Irish – in other words, their status as a non-recognisable, incoherent segment of the white population in the USA – allows for narratives about this group to be highly malleable. Contemporary productions of the Scots-Irish story demonstrate the ways in which ethnic identities emerge as constructions of past and present, memory and history, and politics and culture.  相似文献

Abstract

This paper discusses the understanding of “Common Good” that has been used by the Church of England, especially over the last five years. It suggests that its implicit universalism and identification of Christian morality with the ethical norms for the nation is premised on an understanding of the role of the Church which is no longer realistic. After a brief discussion of the latest statistics for church attendance and a comparison with other national churches in Northern Europe, I suggest that the Church of England is a “small church” and even that Christians constitute a religious minority. This means that the pursuit of the “Common Good” as defined by the church may simply be a piece of nostalgic longing for the time of the “big church.” The recent exclusions for the churches on same-sex marriage legislation indicate that the gap between most of the churches and the wider society. Rather than defining the common good, I suggest that in a pluralist society the churches which recognize their limited role will need to build alliances and common causes with other groups, both religious and secular.  相似文献

In Chinese traditional timber buildings, stitching is very common. When the bearing capacity or the rigidity is inadequate, a timber beam is often strengthened with another beam using the stitching method. The timber stitching beams are mainly of two types—the small-top/big-bottom type and the big-top/small-bottom type. To study the bending behavior of these two types of timber stitching beams, including the failure mode, the flexural capacity, the strain distribution at mid-span section, and the maximum deflection, bending tests are carried out on 14 timber stitching beams with Chinese traditional conformation for seven pine beams and seven fir beams. The results show that the failure modes of the small-top/big-bottom type of stitching beams all show brittle fractures at the bottoms of the bottom beams. The failure modes of the big-top/small-bottom type of stitching beams all show brittle fractures at the bottoms of the top beams. The distribution of section strain along the height of each part of the beam basically obeys plane hypothesis. Based on the theoretical and experimental analysis, the calculation formulas of flexural capacity and maximum deflection of these two types of timber stitching beams made of pine and fir are presented.  相似文献

In the fourth millennium BP, there were major environmental and cultural changes on the Andean altiplano of South America, but the chronology remains vague. A recent synthesis describes a slow, gradual transition from hunting and gathering to agropastoralism. This proposal is tested by refining the date of the onset of more humid and stable conditions, around 3550 cal BP, based on a Bayesian model of 26 dates from Lake Wiñaymarka and an updated calculation of the lacustrine offset. This is compared to Bayesian models of 191 dates from 20 archaeological sites, which incorporate a number of recently processed radiocarbon dates. A synthesis is presented of 15 full coverage surveys, a summed probability distribution, and a Bayesian model of the transition to ceramics, which together support a scenario of a very rapid demographic increase. Fourteen models from archaeological sites are cross-referenced in a composite model, which identifies a brief, altiplano-wide emergence of agropastoralism with starting and ending boundaries of 3540 and 3120 cal BP, respectively. This starting boundary correlates strongly with the onset of improving environmental conditions, indicating synchronous cultural and environmental change. The suite of accelerating cultural changes included a marked reduction in mobility, a demographic surge, increased subsistence diversity, the adoption of ceramics, farming and the integration of camelid herding into a remarkably resilient economic strategy still in use today. This is a highly relevant but yet to be used comparative case study for the variable tempos of ‘big histories’, and ecocultural interactions that generate rapid, emergent episodes of wide-spread and enduring cultural change.  相似文献

Initiated by geoscientists, the growing debate about the Anthropocene, ‘planetary boundaries’ and global ‘tipping points’ is a significant opportunity for geographers to reconfigure two things: one is the internal relationships among their discipline's many and varied perspectives (topical, philosophical, and methodological) on the real; the other the discipline's actual and perceived contributions to important issues in the wider society. Yet, without concerted effort and struggle, the opportunity is likely to be used in a ‘safe’ and rather predictable way by only a sub‐set of human‐environment geographers. The socio‐environmental challenges of a post‐Holocene world invite old narratives about Geography's holistic intellectual contributions to be reprised in the present. These narratives speak well to many geoscientists, social scientists, and decision‐makers outside Geography. However, they risk perpetuating an emaciated conception of reality wherein Earth systems and social systems are seen as knowable and manageable if the ‘right’ ensemble of expertise is achieved. I argue that we need to get out from under the shadow of these long‐standing narratives. Using suggestive examples, I make the case for forms of inquiry across the human‐physical ‘divide’ that eschew ontological monism and that serve to reveal the many legitimate cognitive, moral, and aesthetic framings of Earth present and future. Geography is unusual in that the potential for these forms of inquiry to become normalised is high compared with other subjects. This potential will only be taken advantage of if certain human‐environment geographers unaccustomed to engaging the world of geoscience and environmental policy change their modus operandi.  相似文献

1971年印巴危机是冷战时代一次具有重大国际影响的地区危机。危机期间,因受东巴内战与印巴冲突的双重影响,大量东巴居民逃往印度,沦为难民。东巴难民持续涌入印度不仅是东巴危机转变为印巴危机的主要诱因,同时也是导致南亚持续紧张、敌对氛围难以消解的重要根源。为妥善解决难民问题,美国积极谋划,投入大量人力、物力、财力,意图妥善解决难民问题,化解危机。但是美国采取的积极措施并未减缓危机冲突的不断升级。在处理难民问题的过程中,美巴政策协调趋于一致,而印度与美巴在难民问题上的政策倾向却渐行渐远。归根究底,是否应该在难民问题上附加最终促成东巴独立的政治条件是美巴与印度的根本分歧所在。而这一根本分歧的悬而未决最终成为引爆第三次印巴战争的导火索。  相似文献

新中国建立前夕,鉴于英美在华的利益侧重点、外交传统以及与国民党及其政府的历史关系存在不同,两国在对华政策上出现分歧,最终在诸如是否撤出中国、是否对新中国实施贸易管制以及是否打破国民党对上海的封锁等系列问题上立场迥异,争执激烈,并最终各行其是。根本而言,这是英美经通盘考虑后从自身利益出发所做出的政策抉择,同时也是两国不同的外交传统在对华政策层面上的集中体现。  相似文献

抗日战争爆发后,南京政府认识到抗战将是持久战,持久抗战的关键之一在于农村能否持久地提供支持。因而,维持和发展农村经济就成为坚持抗战的重要一环。而维持和发展农村经济的关键又在于是否能够为农村提供金融支持。本文以台湾"中研院"近代史研究所档案馆藏有关资料为中心,特别是农林部中央农业实验所农业经济系所作的农村金融调查资料,辅以其他史料,对1939年至1944年间国统区15个省的农村金融借贷、放款利率、放款期限、借贷办法、放款机关等情况进行具体考察,分析和观察其成效与特点,并与抗战前后的情况进行比较,以期对抗战时期国统区的农村金融发展和演变情况,有一个较为清晰的认识。  相似文献
