抗战胜利后国民政府的棉纱布抛售政策研究

本文主要探讨抗战胜利后在纺织事业管理委员会(代表国民政府)之管制下,中国纺织建设公司(代表国营纱厂)和上海及苏浙皖区棉纺织工业组成的第六区机器棉纺织工业同业公会(代表民营纱厂)实行棉纱布抛售政策的过程,进而探析纺织资本家对该政策的态度及其与政府的关系.     

夏时期岳石文化的铜器补遗——东夷式青铜重器之推考

海岱地区岳石文化出土的种类繁多的铜质小工具,尤其是合范冶铸的青铜镞和新出现的一些东夷式青铜礼器如鼎、鬲、甗、戈等,不仅体现了岳石文化较高的青铜冶铸水平,也反映了夏、商、夷三族文化之间的交流和融合。     

Cooperation differs. Intentions of municipalities towards metropolitan cooperation in post-socialist space – Brno,Czech Republic

The long-term regional policy of metropolitan regions contributes to the socio-economic development of the entire functional region as it prevents the disharmony in the activity of the interested actors. In the Czech environment, metropolitan cooperation has not been institutionalized yet, which is remarkable while its importance is emphasized in many developed countries and the development of metropolitan regions is greatly supported by EU through the tool ITI. Moreover, a fully-fledged expert interdisciplinary discussion on this issue, which would provide valid conclusions for the needs of the planning practice, is developing rather slowly. The presented contribution is filling this research gap by analysing and assessing the potential of municipalities for metropolitan cooperation in post-socialist space (mainly through institutional cooperation), using a relevant literature, assessing the results of a questionnaire survey and empirical experiences from the model territory of Brno metropolitan area (BMA). The results of the research indicate a willingness to set-up more formal institutionalization of metropolitan cooperation. It would be feasible to transfer some competencies to a newly established metropolitan expert platform/agency. However, cooperation is significantly linked to the awareness of its benefits (not only of a financial character) and to the requirement of keeping ‘basic’ self-governing competencies.     

Evolution of Temperature and Moisture Fields in Charles Bridge in Prague: Computational Prediction and Measurements

Charles Bridge in Prague, founded in 1357, is one of the most prominent historical structures in Europe. It interconnects two Prague districts, the Lesser Town and the Old Town districts, separated by the Vltava River. In the past, the bridge underwent a variety of repairs and retrofits. Within the framework of the moderate repair carried into effect in 2007 to 2010, a measuring system was installed in the bridge, and the temperature and moisture content at selected gauge points have been continuously monitored for a period of 2 years. This article presents non-linear, fully coupled modeling of both fields utilizing a parallel version of the simple finite elements (SIFEL) computer code. Its cogency is validated against experimentally obtained data that serve as inputs for the second stage of a thermo-mechanical analysis—the detailed and mechanics-oriented simulations of the bridge as a whole.     

New patterns in the locational choice of immigrants in Spain

During recent years, Spain has experienced an important revolution in its migration flows. With the 2008–2013 Spanish financial crisis, the model of economic growth that attracted a large number of foreign people disappeared, and the entry of immigrants for reasons other than economic issues gained relevance. Linked with this phenomenon are the new patterns of locational choice across provinces and the variation in the nature of immigrants. In this paper, we examine the differential patterns and drivers of immigration across Spanish regions before and after the financial crisis. Special attention is paid to the question of how the characteristics of individual migrants influence their locational preferences. To answer this question, we use the Dirichlet multinomial regression model. The results obtained show a sharp change in the locational patterns of Spanish immigrants after the economic recession, confirming that traditional economic incentives are less relevant, while non-economic factors linked with a better lifestyle gain importance. They also reveal that, regardless of the economic conditions, network effects are strong. Finally, and what is probably more important for us, our estimates support the hypothesis that the locational preferences rely on the interaction between the immigrants’ characteristics and the underlying locational features.     

辽中京遗址采集细白瓷的成分分析及年代问题研究

为合理编制《辽中京遗址保护规划》,规划课题组对辽中京的历史沿革和遗址遗存进行了全面的调查、研究和评估。为此,采用能量色散X射线荧光(EDXRF)分析方法,对采集自内蒙古宁城县辽中京遗址的细白瓷进行了主量元素测定。所测数据与定窑、龙泉务窑细白瓷文献数据进行比较。统计显示所采细白瓷中67%落在定窑五代至北宋产品主成分区域内,说明遗址内细白瓷主要为辽代遗存,多产自北宋的定窑,充分反映了宋辽之间的密切交流。结合科技分析结果,推断城址内部分夯土遗存可以早至辽代晚期或金初。研究结果有助于确定辽中京遗址的辽代遗存,为保护规划的编制提供了科学依据。     

独乐寺观音阁辽代十一面观音像的材质分析

独乐寺观音阁内十一面观音像保存至今,泥胎存在裂隙、空鼓、脱落等病害。利用超景深三维显微镜、X射线衍射分析(XRD)、激光粒度分布仪等对观音像泥胎进行了材质分析。通过控制砂、纤维含量,分析泥塑试样的收缩性,并探索纤维含量对泥胎收缩性的影响规律。结果表明:观音像泥胎的制作原料取自当地,其中土颗粒粒径多在5~70 μm之间,约占总量的79.5%;主要矿物成分为石英和伊利石,还有部分钠长石和钾长石,以及少量的高岭石。粗泥层含砂量约为35%,麦草(麦秆及麦壳混合物)含量约6%~9%,长度大多在2 cm以下;细泥层含砂量约为30%,麻丝含量约2.1%,长度大多集中在2 cm。麦草和麻丝的加入对泥胎的收缩均能起到抑制作用。随着麦草含量的增加,抑制作用呈现先增大后减小的趋势,掺和6%的麦草抑制作用最好;添加麻丝可使试样的最终线缩率显著减小,但麻丝的多少对线缩率的减小幅度影响不大。观音像泥胎的原纤维配比就有很好的抑制收缩效果。本次研究获得了十一面观音像泥胎的材料组成信息,得出了纤维占比对泥胎收缩性的影响,为十一面观音像的修复与保护提供了参考。     

周恩来的现代科学技术革命思想论析

学术界对于周恩来的科学技术思想研究已经取得了一批成果 ,而对周恩来现代科学技术革命思想的研究则十分薄弱。周恩来是中共领袖中对现代科学技术革命认识最早、阐发最系统的一位杰出代表。对于现代科学技术革命的迅速崛起 ,周恩来不是漠然置之 ,而是积极主动的正视它、探讨它。周恩来关于现代科学技术革命的思想 ,具有鲜明的前瞻性、务实性和创造性 ,是中国共产党人顺应历史潮流、勇于迎接时代挑战的重要思想结晶。
