Flexural Behavior of Typical Chinese Traditional Timber Stitching Beams

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.     

建国前夕英美对华政策的分歧及其原因

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。     

China’s Evolving Policy towards the Democratic People’s Republic of Korea under Xi Jinping

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.     

Doxographical or Philosophical History of Philosophy: On Michael Frede's Precepts for Writing the History of Philosophy

Summary

In a series of articles from the 1980s and 1990s, Michael Frede analysed the history of histories of philosophy written over the last three hundred years. According to Frede, modern scholars have degenerated into what he calls a ‘doxographical’ mode of writing the history of philosophy. Instead, he argued, these scholars should write what he called ‘philosophical’ history of philosophy, first established in the last decades of the seventeenth century but since abandoned. In the present article it is argued that Frede's reconstruction of the history of histories of philosophy is historically problematic.     

Crossing the Great Divides: Hans Aarsleff's Lessons for Nineteenth-Century Intellectual Historians

SUMMARY

This essay discusses Hans Aarsleff's long battle to demonstrate the importance of the French and British thinkers of the mid-eighteenth century to the development of modern linguistic thought. Contesting claims that German scholars were the first to develop historicised theories of language, Aarsleff, along with his Princeton colleagues Lionel Gossman and Anthony Grafton, helped pioneer longue durée studies of the history of philology and of historiography that cross national boundaries as well as the so-called Sattelzeit (stretching from about 1780 until 1820). Although the importance of his work was, for a long time, little appreciated by modern intellectual historians, this essay argues that it is time that we fully learned Aarsleff's lessons.     

RACE AND ANIMAL‐BREEDING: A HYBRIDIZED HISTORIOGRAPHY

Because it associates animals with one of the most vital topics in human history, the historiography of the cross‐connections between race and animal‐breeding is at once controversial and inspiring. This article wishes to position this historiography in a more systematic framework than has been done thus far by examining both its merits and failings along with the more and less appropriate ways to write on the subject. The article identifies two main narratives in race–animal‐breeding historiography: the influence narrative and the projection narrative. The first reveals how perceptions of animal breeds and livestock‐breeding practices influenced the rise of racialist and eugenic worldviews. By contrast, the second shows how conceptualizations of human racial segregation contributed to the construction of ideas about the subdivision of domestic animal species into different breeds. The article argues that despite the projection narrative's inherent anthropomorphism, this perspective renders it possible to draft a nonanthropocentric history of the cross‐connections between race and animal‐breeding with a focus on human–animal relations rather than on human society.     

THE HISTORIAN AS A PUBLIC MORALIST: ON THE ROMAN ORIGINS OF A SCHOLARLY PERSONA

In her recent book, Virtus Romana, Catalina Balmaceda provides a fascinating analysis of the concept of virtus in Roman historiography. Although virtus, which translates as courage or more generally as virtue, meant different things to different Roman historians, Balmaceda shows that disagreement was never about whether historians should provide readers with examples of virtue. Historians' differences of opinion focused rather on where such models were to be found and what they should look like. This review essay summarizes Balmaceda's main arguments, raises a question about historians' own virtus, and draws some implications from the book for the study of scholarly personae. Did the persona of the historian as a public moralist, such as is known from nineteenth‐century Europe, originate in ancient Rome?     

中国古代漆器的锥画艺术和鎗艺术

考古发现的汉代漆器"锥画",是用作画工具"锥"来命名的艺术形式,称为"针刻"欠妥。锥画发明于战国时期,但尚未见到实物。汉代漆器锥画高度繁荣,大量汉代锥画漆器陆续出土。三国至唐时期,锥画鎗金艺术得到了继承和发展;及至宋元,漆器锥画鎗金以全新的面貌出现;发展到明清,锥画鎗金多与其他漆器艺术形式相结合,呈现出千文万华的漆艺局面。
