白伞盖佛母：汉藏佛教的互动

迄今为止,在1267元世祖忽必烈以佑国所举行的白伞盖佛母仪轨仍然被认为是汉地白伞盖佛母崇拜的起源。但是查阅《大藏经》和敦煌汉文写本可以看出,白伞盖佛母崇拜之主要经典在8世纪已经在中国广为人知。由于白伞盖佛母具有特大的保护力量,类似于忽必烈汗14世纪举办的仪式在8—10世纪的敦煌地区已曾在汉人中流传,但这种传统随后在汉地衰落下去了。由于《白伞盖陀罗尼经》组成了《大佛顶首楞严经》第七卷的核心部分主旨也发生了改变。到元代和清代,白伞盖佛母护国的传统在汉地再次得到恢复。     

湖北随州枣树林墓地青铜器表面纹饰的填彩分析

春秋时期青铜器表面装饰技术发展迅速,装饰方法多样,纹样繁复,纹饰中多有填彩现象以凸显其表面图案的装饰性,但目前与此相关的科技分析较少——相关研究多围绕其艺术价值和文化含义展开,尤其是白色填彩的分析仍处于空白。湖北随州枣树林墓地是春秋时期诸侯国曾国的一处高等级贵族墓地,出土了大量的青铜器。本研究使用红外光谱、扫描电子显微镜-能谱、X射线衍射和热裂解气相色谱-质谱联用等手段,对该墓地出土青铜器表面纹饰阴线中的白色填充物质进行分析,结果表明其主要成分为石英和某种黏土矿物混合而成。该研究为东周时期青铜器表面纹饰的填彩工艺提供了新的证据,可为相关研究提供借鉴。     

Foreign Policy Reviews and Canada's Trade Policy: 1968–2009

Governments, upon assuming office, most often seek to refocus foreign policy according to the preferences of the new prime minister and the primary means of accomplishing this has been to release a white paper outlining the priorities of the new government. This article will demonstrate that discussions of trade issues reinforce existing studies questioning the innovation and impact of white papers. The purpose of this analysis, however, is not to dwell on the utility of white papers and foreign policy reviews but instead search for a deeper understanding of why trade policy is discussed in an unoriginal and superficial manner. The focus of the article is on the period from 1968 to the present.     

Sentinel Butte: neutron activation analysis of White River Group chert from a primary source and artifacts from a Clovis cache in North Dakota,USA

Instrumental neutron activation analysis (INAA) was used to characterize the chemical composition of chert from a primary source in western North Dakota. Known as Sentinel Butte, this source is part of the Eocene-age White River Group (WRG), a widespread geological formation on the central and northern Plains. INAA results demonstrate that it is chemically distinct from other known chert-bearing WRG. Further, analysis of three bifaces from the nearby Beach Clovis cache site demonstrates that they are made of chert from Sentinel Butte, and most likely the other 55 White River Group Silicate (WRGS) bifaces in the cache are as well. Although Clovis caches typically are dominated by materials transported hundreds of kilometers, it is argued that the advance manufacture and caching of bifaces even a short distance from a source may be a highly effective tactic to reduce gearing up time and hence search costs associated with the pursuit of mobile game at the close of the Pleistocene.     

Exploring normative whiteness: ensuring inclusive pedagogic practice in undergraduate fieldwork teaching and learning

Higher education commentators have become concerned about how learning and teaching praxis across the sector may unwittingly advantage White British (WB) compared to Black and Minority Ethnic (BME) students. Adopting critical race theory, this article explores these issues in relation to field teaching in geography and related subjects. It reports on primary data collected from students about to attend their first residential field trip. The research shows that WB and BME students approach their first field trip with diverse geographical experiences. The findings indicate a need to reflect critically on our fieldwork routines in order to promote inclusivity in field learning.     

苏区时期的"赤白对立"--阶级革命中的非阶级现象

赤白对立是指苏维埃区域与非苏维埃区域之间的对立,出现于苏区周边地区,它不是由土地革命加剧的阶级间的对立,而是一种非阶级的由多种因素引发的以地域为中心的冲突。赤白对立的出现,既有中共自身的原因,也有国民党方面的推波助澜,还缘于社会革命与社会组织间的内在冲突。就中共方面看,前期和后期造成这一现象的原由也不尽相同。赤白对立给中共开展革命造成很大不利影响,某种程度上成为苏维埃时代的一个痼疾。     

Optimum Design of Passive Control Devices for Reducing the Seismic Response of Twin-Tower-Connected Structures

Based on the 3-single-degree-of-freedom (SDOF) model of twin-tower structures linked by the sky-bridge and passive control devices, the frequency functions and the vibration energy expressions of the structures are derived by using the stationary white noise as the seismic excitation. The analytical formulas for determining the connecting optimum parameters of viscoelastic damper (VED) represented by the Kelvin model and the viscous fluid damper (VFD) represented by Maxwell model are proposed using the principle of minimizing the average vibration energy of either the single tower or the twin tower. Three pairs of representative numerical examples of twin-tower-connected structures are used to verify the correctness of the theoretical approach. The optimum parametric analysis demonstrates that the control performance is not sensitive to damper damping ratio of VED and relaxation time of VFD. The effectiveness of the proposed control strategies based on the 3-SDOF models is also proved to be applicable to multi-degree-of-freedom systems. The theoretical analysis and numerical results indicate that the seismic response and vibration energy of the twin-tower-connected structures are mitigated greatly under the two types of dampers. The presented control strategies of VED and VFD can help engineers in application of coupled structures.     

Presidential Oral History: The Clinton Presidential History Project

Most conventional oral history takes a bottom-up approach tothe past, focusing on settings where there is little in theway of a functional written record. This essay discusses thevalue of oral history in the opposite case of the American presidency.The written archive and journalistic record on each presidentis immense. Yet oral history is a valuable resource in thiselite environment, too. There are routine silences in even thebest of presidential papers, which oral history interviews canhelp fill. Moreover, the White House has become a workplacewhere recorded details can be hazardous to one's political health.Accordingly, few presidential aides today keep diaries or notesof key meetings—impoverishing the archive future historianswill use to study the presidency of our times. Oral historythus fortifies a weakening documentary record. This essay exploresthese broad issues and how they are being dealt with in theconduct of the William J. Clinton Presidential History Project.     

Spying in the British Post Office,Victorian Politics and Wilkie Collins’s The Woman in White

In 1844, the British public learned that the government was secretly opening exiled Young Italy leader Giuseppe Mazzini’s private letters and sharing information with continental authorities. For outraged citizens, espionage in that quintessential liberal institution, the reformed British Post Office, appeared un-English, despotic and criminal, the makings of a Gothic plot. Representations of the Post Office Scandal in Parliament and print predict the revision of the Gothic into the sensation novel that occurred with the publication of Wilkie Collins’s The Woman in White. Attention to the fields of Anglo-Italian studies, mid-Victorian print culture and the development of narrative form in the mid-nineteenth century illustrates the historical and political implications of letter-opening for the emergence of a new fictional genre. The Post Office Espionage Scandal and The Woman in White share a central place in a mid-Victorian moment of evolution in the mutually constitutive relationship between Italian and British national identities, producing and reflecting a crisis in Britishness focused on the secret tyrannies concealed beneath the surface of Victorian liberalism. The letter-opening scandal reveals a crisis in Victorian liberalism in the political realm and the media, while The Woman in White translates this Victorian crisis of confidence into a literary genre defined by exposing the sordid undercurrents of British society: sensation fiction. Together, the espionage scandal and Collins’s novel respond to and generate a challenge to Victorian complacency that emerged out of the collision of British and Italian politics and culture in the mid-nineteenth century.
