论碧霞元君信仰的起源

泰山碧霞元君是中国历史上影响最大的女神之一,尤其是明清以来,她在民间的影响已经大大超过了泰山主神东岳大帝,以至于当时的文人士子对碧霞元君势力     

建国初期社会救助体系的构建与评析--以1949～1953年的广州市为个案

建国初期,中共在广州构建了一个过渡性的社会救助体系,在短短的4年内,广州市通过它救助了大量的失业者和城市贫民,基本上遏制了由于新旧转轨带来的社会危机,为新政权即将展开的社会主义各项建设奠定了基础.在救助理念和救助过程上,它体现了以往社会救助的一些特点,同时也反映了我党的诸多特色,诸如鲜明的意识形态性、广泛的群众参与性和严格的组织纪律性,隐隐约约闪烁着以统一调配为主要特征的计划时代社会政策的影子.     

《太平经》易学思想初探

东汉后期,政治腐败,社会黑暗,许多思想家、政治家致力于探求除弊救世的良方.在社会批判思潮兴起的同时,道教迅速形成并发展起来,《太平经》也随之成书.作为最早的道教经典,《太平经》继承、发挥《周易》之道,充分吸收各种易学成果,提出了一系列独具特色的易学思想,成为易道融合的典范.关于这一问题,前人及时贤多有述及,但系统论述者尚不多见.有鉴于此,笔者撰成本文.不妥之处,敬请方家教正.     

20世纪30年代日本对我国南沙群岛政策的演变

20世纪30年代,日本对我国南沙群岛政策呈现出阶段性变化。1933年“九小岛事件”发生之际,日本在对外政策中坚持“协调外交”路线,与法国达成妥协,实现共存。1936年当“南进”政策成为日本的国策时,向我国南沙群岛的扩张成为日本实施向外南洋扩张计划中的一部分。随着日本军部逐渐主导国家对外决策及国际局势的新变化,日本外务省从极力反对海军省的行动演变为积极献策,一致主张驱逐法国势力,武力侵占我国南沙群岛。1939年3月末,日本将我国南沙群岛非法“编入”领土。20世纪30年代日本对我国南沙群岛政策演变是日本外务省、海军省基于国内政治与国际时局综合考量,也是他们分歧、折冲、平衡的结果。     

从中河通判万承紫罢官案看道光朝江南河工——兼考万承紫的淮安清江浦生涯

周恩来外曾祖父万承紫,道光初任南河中河通判,因收藏两江总督琦善看中的元代《龙舟图》被琦善弹劾免职。从该案中可见道光时两江总督对江南河工事务的介入、江南河工的奢侈之风,以及南河官场的文化氛围。万承紫尚风雅,收藏甚富,与寓居、往来南河的文人墨士多有交游,罢官后所居"还读书室"为文人雅集之所。原籍南昌的万家因河工而移居于南河治理中心淮安清江浦,万承紫子孙辈也精于河工。万家三代的治水经历也对周恩来产生影响,任总理期间特别重视水利事业。     

南京明代宝船厂遗址出土舵杆结构特征研究

南京明代宝船厂遗址的发掘及船舶构件的出土,为研究郑和下西洋活动,尤其是郑和船队的相关信息提供了宝贵的资料。宝船厂遗址中出土的舵杆是船舵的重要组成部分,也是复原船舵的主要依据。通过对舵杆本体特征部位与古代不平衡舵的比较研究,对舵首、舵身、舵尾特征部位的结构、功能进行了深入、细致的分析研究,初步完成了船舵的结构、功能和操控系统的复原。     

Naval Battlefield Archaeology of the Lost Kublai Khan Fleets

From AD 1274 Chinese emperor Kublai Khan dispatched fleets of ships in a series of attempts to expand the empire's hegemony and extend his rule into East Asia (Japan) and Southeast Asia (Vietnam, Champa and Java). Archaeological remains associated with the fleets and battles have been found at Takashima Island, Japan and on the B?ch Ð?ng River, Vietnam. This paper develops a thematic approach to these sites within a framework of naval battlefield archaeology. It compares the similarities and differences in environmental conditions and archaeological contexts of the two sites in Japan and Vietnam. It also outlines recent archaeological research conducted between 2008 and 2010 on the physical remains at the B?ch Ð?ng River battlefield site.     

Development of Collaborative Structure Analysis (CSA) System and Its Application to Investigate Effects of Soil-Structure Interaction

In this article, a collaborative structure analysis (CSA) system is developed for integrating different finite-element simulation programs. In this system, a simulated structure is divided into multiple substructures, and the interaction between the substructures is considered. Interfaces for the commercial finite-element program ABAQUS and for an open-source framework for structure analysis, OpenSees, are developed to achieve CSA integration. The CSA system is applied to analysis of a soil-structure interaction (SSI) problem, and the effects of SSI are investigated, and the efficiency and accuracy of the system are demonstrated.

Estimating the number of components in an OSL decay curve using the Bayesian Information Criterion

The optically stimulated luminescence (OSL) decay curve is assumed to consist of a number of first-order exponential components. Improper estimation of the number of components leads to under-or over-fitting of the curve under consideration. Hence, correct estimation of the number of components is important to accurately analyze an OSL decay curve. In this study, we investigated the possibility of using the Bayesian Information Criterion to estimate the optimal number of components in an OSL decay curve. We tested the reliability of this method using several hundred measured decay curves and three simulation scenarios. Our results demonstrate that the quality of the identification can be influenced by several factors: the measurement time and the number of channels; the variability of the decay constants; and the signal-to-noise ratios of a decaying component. The results also suggest that the Bayesian Information Criterion has great potential to estimate the number of components in an OSL decay curve with a moderate to high signal-to-noise ratio.
