中国女真族的领土意识初探

早在女真族初步形成之时,居住于朝鲜半岛北部的西女真和东女真就将家园视为中国之内的封境。高丽北进,女真则失去了大片土地。辽朝末年,为保卫家园,女真人在曷懒甸(今咸兴平原)大败高丽军。在朝鲜王朝占领半岛东北部以后,女真首领王可仁、佟景再三提醒明成祖,朝鲜所占之地乃是女真人的旧土,但由于彼时明朝君臣对该地历史的不确知,十处女真居地被送与朝鲜。     

弘扬人文精神编纂文献志

文献志编纂由来已久,当代编文献志是激活传统的文征、文献志体。文献志全面记述一地各类有历史价值或参考价值的图书资料编纂出版情况,内容以艺文志为主,同时涵盖自然、经济、政治、社会、科学技术等方面的著述文献。参照现代文献分类,可分为哲学社会科学类文献,基本要素11小类;自然科学类文献,基本要素9小类。省级志书文献志还应该设置综合性图书类,直接分为丛书,百科全书、类书,辞典,论文集、全集、选集、杂著,年鉴,期刊、连续性出版物,图书目录、文摘、索引等7小类,主要是编目录,撰提要,录原文。     

Comparison of three K-feldspar luminescence dating methods for Holocene samples

The luminescence dating of the K-feldspar fraction is an alternative way for samples that cannot yield reasonable equivalent dose (D_e) from quartz fraction with very weak luminescence signal. For testing the reliability of the infrared stimulated luminescence (IRSL) dating of K-feldspar, luminescence dating was applied to quartz and K-feldspar fractions respectively for several Holocene samples in this study. K-feldspar apparent ages using routine single aliquot regenerative-dose (SAR) protocol, K-feldspar ages using g value correction method and ages from isochron dating method were compared with quartz ages. It is found that the g value correction method cannot give reliable ages due to the large errors induced during measurements. The isochron dating method is effective to the sample with problematically external dose rate. However, isochron dating may introduce a relatively greater error during grain sizes — D_e curve fitting, therefore this method could obtain low-resolution ages for Holocene samples. Even K-feldspar apparent age from routine SAR protocol is relatively younger by about 10% than the quartz age, it still could establish reasonable chronological framework for Holocene samples.     

Impact Stiffness of the Contact-Element Models for the Pounding Analysis of Highway Bridges: Experimental Evaluation

For the requirement of pounding analysis of highway bridges, how to properly choose the impact stiffness has become a primary issue for an achieving accurate result. This article presents an evaluation test of the impact stiffness of four types of contact-element models based on the shaking table test results of a steel highway bridge model. The analytical results indicate that the theoretical impact parameters are significantly larger than the identified values because the assumptions for deriving those models cannot match the actual impact conditions. The possible reasons causing those differences are discussed at the end of this study.     

Firing temperature of a clay core sample in a bronze tripod from Daxinzhuang Site in China using TL techniques

In this paper, we studied the thermal history of a clay core sample from one leg of a bronze tripod unearthed at Daxinzhuang Site, Shandong, China. The properties of the luminescence signals of quartz depend on the maximum temperature at which the quartz was annealed in the past. We examined the feasibility of measuring the thermoluminescence (TL) sensitivity change of quartz for exploring the firing temperature of archaeological materials. The sensitization factor of the 110°C TL peak (S₂/S₁) and the ratio of the 210°C TL peak to the 110°C TL peak at different annealing temperatures were utilized to unveil the firing temperature in the clay core sample. The firing temperature of the clay core sample was approximately 700°C–800°C, proving the clay core has been fired. This result proved that the clay core has been fired by human agencies and indicated on the temperature of the clay core in drying and firing given by the foundry workers before the actual casting step.     

亚文化消费空间场所依赖维度探索性研究——以大连市泡泡玛特门店为例

在后现代消费时代,文化逐渐成为城市消费空间建构的重要手段。其中亚文化以其有别于主流文化的文化特质,引导人们在消费空间中有着别样的空间实践,进而传递给人们独特的空间感知。本文借助场所依赖理论,以大连市 5 家泡泡玛特门店为例,通过开放式深入访谈和参与式观察等形式的实地调查收集资料,运用扎根理论对资料进行三级编码分析,获得一个由亚文化风格、文化审美、消费空间、休闲时间、社会交往五个维度组成的亚文化消费空间场所依赖理论模型。以期帮助人们更清晰的了解,具有不同身份认同的亚文化群体,在多样的文化消费模式下开展的空间实践过程,以及随之产生的空间情感联系。

本文基于城市视角编制了旅游景气指数,并从理论上建立了包括先行指数、一致指数、滞后指数的旅游景气指数体系。本文以北京为例,运用月度数据编制了2007年-2012年入境旅游景气先行指数和一致指数,分析了在此期间北京入境旅游市场的波动情况及成因,揭示了先行指数和一致指数之间存在的时滞关系,以期为政府管理机构和旅游企业准确判断城市旅游业的发展并预测未来的动向、制定相关政策提供一定的依据。     

The godly re-presentation of Alexander Nyndge: two versions of a Protestant dispossession narrative

ABSTRACT

The sixteenth-century account of Alexander Nyndge’s dispossession saw republication in 1615. Yet this was not a mere reprint: alterations included passages borrowed from notable puritan authors George Gifford, John Darrel, and Edward Dering, and an invitation for audiences to take the account as an example. From the 1590s, the English national church’s responses to (typically puritan) minister-led dispossessions by prayer and fasting had restricted opportunities for the godly to perform and publicize dispossessions. However, republishing the Nyndge account with alterations enabled circulation of a godly dispossession narrative adapted to a contemporary context.

With limited source materials after c. 1600, historians have had difficulty assessing continuities and changes in puritan ideas about dispossession. Yet comparing the two versions of the Nyndge publication and considering how the revision fit within a post-1604 context provide a window into how views and practices were developing over the early decades of the seventeenth century.     

Two new species of Mesosciophilidae (Insecta: Diptera: Nematocera) from the Yanliao biota of Inner Mongolia,China

Wang, Q., Zhao, Y.Y. & Ren, D., December 2012. Two new species of Mesosciophilidae (Insecta: Diptera: Nematocera) from the Yanliao biota of Inner Mongolia, China. Alcheringa 36, 509–514. ISSN 0311-5518.

Two new species assigned to Mesosciophila Rohdendorf and Paramesosciophilodes Zhang in the Mesosciophilidae are described and illustrated: Mesosciophila sigmoidea sp. nov. and Paramesosciophilodes aequus sp. nov. They are established based on fossil specimens with bodies and complete wings. Both were collected from the Middle Jurassic, Jiulongshan Formation at Daohugou, Inner Mongolia, China.
