建国初期的冀朝鼎

新中国诞生后,百废待兴。冀朝鼎在帝国主义实施禁运和经济封锁的困难面前,积极探索中国外经贸的新体制,加强外汇管理,以灵活的外交,与11个国家签定了外贸协定,还成功地与日本、英国等未建交国家进行“民间贸易”．打破西方列强的孤立政策．开创了中国对外交往与贸易的新局面。     

三朝本《三国志》版本略谈

由于三朝本《三国志》系经过多次补版印刷,其版式不一,对其版本的认识容易产生混乱;综合多方面资料,至少存在三种三朝本《三国志》。     

存世《出师颂》墨迹本与刻本关系考

本文将《隋贤书出师颂》墨迹本与传世《出师颂》的八种刻本进行排比梳理,归纳出三个系统:即“萧子云”系统、“索靖”系统、“隋人”系统。通过各本文字校勘比较和文献考证,证明“索靖”系统刻本的母本即史载北宋“宣和本”,“隋人”系统即史载南宋“绍兴本”,而此两本与北宋《兰亭续帖》所刻“萧子云本”,俱出自同一个更古的祖本。进而对辑入《出师颂》文字的《文选》一书的版本进行分析,论证“绍兴本”应是隋和初唐书家的临摹本,即《隋贤书出师颂》墨迹。     

论"白家庄期"商文化

分布和影响地域广袤的"白家庄期"商文化,因时代接近于商代中期而在商文化中具有承前启后的地位.有关考古新发现显示,"白家庄期"商文化本身可以区分为三个不同的时间段.在其所代表的历史阶段中,郑州商城的衰颓与小双桥商都的兴建形成了鲜明对照.这一现象出现的历史背景是,有关文献所记商王朝此时所面临的内忧外患局面以及仲丁迁隞历史事件的发生.     

"文革"中的知识青年上山下乡运动研究述评

"文革"中的知青上山下乡运动是当代中国的重大事件之一.中外学者对这场运动进行了深入的探讨研究,取得了不少成果,发表了一批论文及专著,整理和公布了许多资料,目前在许多问题上已达成共识,与此同时也存在很大分歧,如关于"文革"中的知识青年上山下乡运动的基本动因问题、历史进程及其评价问题,对知青"返城风"及上山下乡运动终止原因等等,这些都有待研究者进行深入细致的研究.此外,在研究中还存在资料收集困难、研究力量薄弱、研究方法单一等困难与不足.     

Evidence of Metallic Plating on Archaeological Artefacts by Voltammetry of Microparticles

Voltammetry of microparticles using a paraffin‐impregnated graphite electrode (VMP/PIGE) was applied as a very local and non‐invasive analytical technique in order to investigate the presence of remains of metallic plating on two ferrous and one cuprous artefact from the medieval period. The analyses have been performed locally and selectively on regions presenting particular features, such as texture, cohesion and colour differences. The results confirm local differences in chemical composition, leading to conclusions about the presence of metallic plating on these artefacts.     

Identification of Green Pigment Used in Persian Wall Paintings (ad 1501–1736) Using PLM,FT–IR,SEM/EDX and GC–MS Techniques

The technique of oil painting was introduced to Iran via a cultural exchange with Europe in the Safavid period (ad 1501–1736). Since the first attempt at scientific conservation of wall paintings in Iran in the 1960s, the nature of green pigment used in Persian wall paintings has not been clear, although work on contemporary miniature paintings has identified malachite and verdigris. PLM, FT–IR, SEM/EDX, GC–MS and the study of contemporary historical treatises of the Safavid period were the main tools used in the present study to identify the green pigments in Persian (oil‐based) wall paintings. Eight samples taken from the two famous Safavid buildings, Chehel Sotoon Palace and the Sukias House in Isfahan, were analysed. Here, the identification of copper‐based pigment and of verdigris in oil as oleate amends the existing knowledge of the green pigment used in these paintings. It also suggests that oleate was introduced to Persian artists via the European influence on Persian painting as a result of cultural exchange in the Safavid period, when the technique of Persian painting changed from tempera to oil painting. However, as verdigris in oil and resin can appear as oleate over time, it is unknown whether the Persian artists did this deliberately or accidentally.     

Between east and west: Glass beads from the eighth to third centuries bce from Poland

The study analyses the chemical composition of 57 glass samples from 40 beads discovered at 20 archaeological sites in Poland. The beads are dated to Hallstatt C–Early La Tène periods (c.800/750–260/250 bce ). Analyses were carried out using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Two groups were distinguished among the glasses based on the MgO/K₂O ratio: high-magnesium glass (HMG), five samples; and low-magnesium glass (LMG), 52 samples. The former were melted with halophyte plant ash, the second with mineral soda. These glasses were produced in the Eastern Mediterranean (more likely in Mesopotamia or Syro-Palestine than in Egypt) and transported in the form of semi-products to secondary glass workshops in Europe. Some of the white opaque glass was coloured and opacified in Europe.     

中晚唐两制草诏格局的形成及演变

中晚唐两制草诏的区别较鲜明地体现在用纸材质上,从学士院成立之初翰林学士张垍用黄麻写诏,到代宗大历年间以内制白麻任命李栖筠为御史大夫,是翰林学士院草诏制度的一大变化。在早期的白麻内制中,命相制书是最早且较稳定地归属学士院起草的文书类型。至德宗贞元时期,涉及节度使的除命以及赦文德音、招讨宣慰等重要政务处分的诏令起草,开始较为稳定地归属学士院。宪宗元和时期及其以后,通过对元稹、白居易文集等集部文献中所收诏敕予以归类,可大体展现此期两制分工的整体面貌,其中外制黄敕在各品级官僚群体的除授上皆有行用,而内制白麻的行用则大体被限定在常参官以及五品以上外官的除授范围之内。     

About time: age,period, and cohort effects on support for Quebec sovereignty

Can age, period and cohort effects help explain support for Quebec sovereignty? Previous work on this question has focused mostly on the effects of age and cohort. We contribute to this debate by adding a period perspective. As such, our study is the first to investigate the impact of age, cohort and period effects in a single study of opinion towards sovereignty in Quebec. We take advantage of an original dataset that includes survey data collected between 1985 and 2012. We use these data to examine the impact of age, birth year and survey year on support for this constitutional option among francophone Quebeckers. Our results are in line with previous work: we show that younger Quebeckers are more likely to support sovereignty, and that some cohorts – namely, respondents born between 1945 and 1959 – are also more likely to favour this option. Perhaps more surprisingly, we find that specific events are comparatively the most important factor to explain fluctuations in Quebeckers' attitudes towards sovereignty.
