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

雍正三年,台湾县知县周钟蠧被控贪污,由于牵涉到闽台财政改革的大背景,此案引起了雍正皇帝的高度关注,并演变为震动闽台官场的一桩大案,涉案人等都被卷入了皇权与地方官员博弈的大漩涡。案件的审理过程,伴随着闽台财政改革的全过程,从清查仓谷亏空,到耗羡归公和养廉银制度化的最终完成。透过考察周钟蠧案,闽台地区财政改革的过程得以完整呈现。在皇权的强势施压下,闽省官员提出的耗羡归公方案显得仓促而草率。 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

义和团运动时期的北方战事,给包括租界在内的上海及江南民众日常经济生活带来巨大恐慌。身处纷乱的惊惧不安和经济萧条的切实威胁,社会各界普遍企望北方战事早日平息,不致蔓延到南方,这种社会心理氛围,是"东南互保"得以产生和推行的重要原因。 相似文献

Despite international pressure to condemn North Korea (DPRK), China’s successive leaderships have dealt carefully with Pyongyang, especially vis-à-vis its nuclear weapons program. This moderate stance reflects the two countries’ decades-long relationship, summarised in the Chinese idiom that Pyongyang and Beijing are “as close as lips and teeth”. Nevertheless, the DPRK’s third nuclear test in February 2013 raised enormous challenges for the new Xi Jinping leadership to maintain the previous DPRK policy focused on the status quo and stability on the Korean Peninsula. China’s attitudes and policies towards the DPRK after the provocative third test signified a possible reorientation of Beijing’s DPRK policy. This generated repercussions in the countries concerned and prompted debates among experts. This article asks how these events should be understood and what their implications are for the Xi leadership’s policy on the DPRK, the stability of the Korean Peninsula, and Northeast Asia. Given China’s competitive relations with other major powers, we conclude that the Xi leadership will not abandon the DPRK; indeed it will reinforce the policy of strengthening China’s influence over it. Nonetheless one aspect of doing so will involve China opening up to other – cooperative, multilateral – approaches to reinforcing stability on the Korean Peninsula and in Northeast Asia. 相似文献

In 2000, a well‐preserved, c.21 m‐long shipwreck, Doel 1, was found upside‐down in a silted‐up creek near the river Scheldt (Belgium). An interdisciplinary research project was initiated, including 3D registration of all timbers, wood species identification, dendrochronology and archaeobotanical analysis of the caulking material. Doel 1, of which 70% is preserved, displays the construction features of a cog. Unseasoned wood was used and dated by dendrochronology to AD 1325/26. Remarkable features include the symmetrical layout of the bottom planks, the atypical arrangement of the frames to the fore, and evidence of partial dissassembly of the ship after intensive use. 相似文献

Kinship systems cannot be analysed as straightforward translations of the ‘facts of nature’ when those facts are limited to the production of a child by a heterosexual couple. Based upon analyses of three New Guinea societies (Gimi, Daribi, and Iatmul), I suggest that kinship systems take account – often by denying – certain ‘facts’ of human reproduction when those facts are extended beyond coitus and parturition to include both the very long period of infantile dependence upon one significant caregiver (always the mother in the societies in question and nearly universally) and the subsequent requirement for the child to be extracted from a dyadic maternal universe. Separation from mother is as critical to the survival and development of the individual as is the original prolonged and intense attachment to her. The question, then, is not whether indigenous peoples accurately understand coitus and conception – they do – but rather the ways in which they manipulate that knowledge in rules and rites of kinship in order to manage the growth and development of a child long after parturition. Rules of kinship and social relations neither ignore nor exist apart from theories of procreation as many anthropologists now claim. Rather, it is precisely because theories of procreation indicate and idealise the flow of bodily substance during coitus and pregnancy that they serve as organisational premises for social relations. The fact that kinship is a symbolic construction does not mean that it is wholly ideological nor, like a language, free to vary in ways that are arbitrary and unconnected to the ‘facts of life’ as Westerners understand them. Even when interlocutors openly deny such understanding and knowledge, especially of the male role in coitus and conception, evidence to the contrary is abundantly provided in myth, ritual, and indigenous theories of procreation. What kinship systems often do show, however, is a strategic denial of the role of the mother who, upon deeper understanding of indigenous concepts of procreation, turns out to be a ‘sterile vessel’ or without substantial contribution to her child. I illustrate this premise by extending earlier analyses of Gimi kinship and reexamining certain materials on neighbouring Daribi provided by Roy Wagner and on Iatmul peoples of the Sepik River as originally described in Naven by Gregory Bateson eighty years ago. 相似文献

Study abroad offers a specific configuration of encountering cultural Others: in a demarcated “abroad” space in a compartmentalized time period. Informed by Bakhtin's notion of chronotopes, this article investigates narratives of American college students who studied in Paris, France and Bilbao, Spain in June–July 2011 based on an ethnographic fieldwork of their stay. I identify two chronotopes held in tension in their narratives that reflect tenets of the discourse of immersion: of homogeneous space where every minute students spend in the host society is “local” time full of learning, which risks portraying the host society as frozen in the time of the students’ stay; and of heterogeneous space where local space–time and outsider (e.g. American students and tourists) space–time co-exist hierarchically, where students strive to show their engagement with the former. This article calls for encouraging students to examine the effects of these chronotopes on their experiences and for viewing study abroad not as an encounter of two cultures but as diverse students joining in the ongoing production of heterogeneous host society space with a compartmentalized yet expanding notion of time. 相似文献

This paper investigates the context of student learning in study abroad programs, drawing on ethnographic research on a semester long study abroad program in South India. We show how students use multiple constructions of time and space as a framework for understanding cultural differences and for understanding what it means for them to “experience” India. We argue that students' conceptualization of space and time in the study abroad location also impacts what kinds of activities they consider to count as valuable forms of learning. Students' ideas about India shape their expectations of what the pace, workload, and activities of the study abroad program in India should entail. Their concepts of Indian time and space lead them to privilege “experience”-based learning over classroom-based or scholarship-based learning. In conclusion, we show how these insights have implications for study abroad pedagogy. Here, we suggest that student learning that is entirely based on “experience” outside the classroom is inherently limited and that students need to contextualize their field-based learning experiences with insights from critical, historical and social science research. 相似文献
