基于GIS的家谱资源整合集成研究

我国家谱源远流长、内容丰富、数量巨大,一直是众多领域学者关注的焦点。但是,家谱研究始终处于初级阶段,家谱的价值尚未得到充分利用。其根本原因在于家谱资源分布广泛、共享困难、研究方法和手段单一。各方通力合作,利用高新技术整合现有家谱资源,建立中华家谱总数据库和总平台已迫在眉睫。本文针对家谱典型的时空特性,提出采用GIS技术整合集成海量家谱资源,并进一步探讨了家谱资源整合集成的若干关键问题,设计了家谱资源整合集成的基本原则和平台框架,为家谱研究提供了新的思路、方法和技术。     

Jet-Pacs Project: Dynamic Experimental Tests and Numerical Results Obtained for a Steel Frame Equipped with Hysteretic Damped Chevron Braces

The experimental and numerical results obtained by Research Units of the University of Basilicata and University of Calabria for a steel frame, bare or equipped with metallic yielding hysteretic dampers (HYDs), are compared. The shaking table tests were performed at the Structural Laboratory of the University of Basilicata within a wide research program, named JETPACS (“Joint Experimental Testing on Passive and semiActive Control Systems”), which involved many Research Units working for the Research Line 7 of the ReLUIS (Italian Network of University Laboratories of Earthquake Engineering) 2005–2008 project. The project was entirely founded by the Italian Department of Civil Protection. The test structure is a 1/1.5 scaled two-story, single-bay, three-dimensional steel frame. Four HYDs, two for each story, are inserted at the top of chevron braces installed within the bays of two parallel plane frames along the test direction. The HYDs, constituted of a low-carbon U-shaped steel plate, were designed with the performance objective of limiting the inter-story drifts so that the frame yielding is prevented. Two design solutions are considered, assuming the same stiffness of the chevron braces with HYDs, but different values of both ductility demand and yield strength of the HYDs. Seven recorded accelerograms matching on average the response spectrum of Eurocode 8 for a high-risk seismic region and a medium subsoil class are considered as seismic input. The experimental results are compared with the numerical ones obtained considering an elastic-linear law for the chevron braces (in tension and compression), providing that the buckling be prevented, and the Bouc-Wen model to simulate the response of HYDs.     

Electron paramagnetic resonance of mosaic glasses from the Mediterranean area*

Ancient mosaic glass tesserae sampled from archaeological sites located in the Mediterranean area have been analysed by Inductively Coupled Plasma‐Optical Emission Spectroscopy (ICP‐OES). The aim of the research was to understand the role played by 3d transition metals in the optical properties of such samples. In order to better identify the specific effect of the main chromophorous element, modern samples have been prepared in the laboratory by adding to a colourless base frit controlled concentrations of colouring oxides. Samples with compositional and optical properties similar to the ancient ones have been obtained. For all these modern samples, as well as for all the ancient ones, electron paramagnetic resonance (EPR) measurements have been performed. The features of the EPR spectra could be successfully associated with the presence and abundance of the paramagnetic colouring ions (namely iron, manganese and copper) and to their oxidation states. This could be a basic step towards understanding the provenance and chronological attribution of mosaic glass tesserae.     

Seismic History of the Church of San Pietro Di Coppito in L’Aquila

After the terrible 18th-century earthquakes—in L’Aquila in 1703, Lisbon in 1755, and Reggio Calabria in 1783—specific anti-seismic precepts were introduced in the rules of the art of masonry construction. Scrupulously adhered to in the first years after the earthquake, those precepts gradually ceased to be used until they were almost completely forgotten, centuries later, by which time the earthquake had become a distant memory. The church of San Pietro di Coppito, one of the most important churches of L’Aquila, is emblematic of this singular process. Deeply transformed in accordance with new anti-seismic construction techniques after it was particularly badly damaged in the terrible 1703 earthquake, the church was subjected, in the 1970s, to drastic alterations by the Commissioner Mario Moretti, who demolished all the baroque additions and redesigned it in the “medieval Abruzzo” style, eliminating in the process the intelligent anti-seismic provisions introduced in the 18th century. In addition to documentary purposes, this work aims to underline the effectiveness of this early 18th-century example of anti-seismic engineering in the belief that the constructive solutions it employed could still form a valid architectural and structural model in view of the massive restoration task for which, unfortunately, L’Aquila is still waiting today.     

Disclosing mineralogical phases in medioeval iron nails by non-destructive neutron techniques

There is not only one methodology for the study of mineralogical phases in archaeological samples. In this paper, we discuss a strategy applied to ancient iron nail samples completely based on non-destructive analyses. The archaeological samples come from the archaeological site of Valle delle Forme (province of Brescia–Italy) and date back to the 1300–1400 ad. Neutron-based techniques, like time-of-flight neutron diffraction and neutron tomography, have been used to determine the mineralogical composition and the structure of nails. An independent check for the assessment of the presence of different mineralogical phases was given by Raman spectroscopy. The combination of different non-destructive techniques has provided very useful information on their chemical composition, nature of the patina and corrosion features of the nails (also in the bulk of the samples).     

海外所藏两铺河北地区北魏金铜释迦多宝并坐像名品探析

两千载一气呵成的中国佛教史中无疑烙有世俗权力的深刻烙印,如北魏中晚期释迦多宝二佛并坐造像的风靡一时,即与其作为孝文帝、冯太后“二圣政治”宗教宣传品的现世功用不无关联。河北地区系北朝施造铜、石单体释迦多宝二佛并坐像的根据地之一,本文选取流失海外的两铺出自河北地区的北魏金铜二佛并坐像名品加以探析。     

Stable isotope analysis of Late Upper Palaeolithic human and faunal remains from Grotta del Romito (Cosenza), Italy

Stable isotope analysis of carbon (δ¹³C), nitrogen (δ¹⁵N) and sulphur (δ³⁴S) were carried out on one of the largest assemblages of Late Upper Palaeolithic human remains in Southern Europe, at Grotta del Romito (Cosenza), Italy. The burials were stratigraphically dated from ca. 18,000 to 13,000 cal BP, which was confirmed by a series of new AMS dates made directly on the bone collagen. Dietary reconstruction from carbon and nitrogen stable isotopes revealed that eight of the nine individuals analysed, dating to the Final Epigravettian, had very consistent diets, rich in terrestrial animal protein, regardless of their age or sex. These included two individuals who were suffering from severe pathologies. A single individual, dating to the Evolved Epigravettian had a more variable diet, which was significantly enriched in protein from marine or freshwater fish compared to the later burials. Overall, the results are consistent with the very limited number of other studies which describe a change to more specialised and less variable subsistence strategies, in this case the hunting of large herbivores, towards the end of the Palaeolithic period. Sulphur isotope values of all of the nine burials and several faunal samples were notably consistent, showing no evidence of long-distance migration to the site from a different geological zone.     

茶馆、戏园与通俗教育——晚清民国时期成都的娱乐与休闲政治

晚清民国时期的茶馆戏园,作为公共空间为大众提供娱乐,从中除了可以了解人们在茶馆戏园的日常生活外,还可以看到改良精英和地方政府竭力改革戏曲作为控制大众娱乐的一部分,把他们的政治灌输在表演的节目之中,把他们所认为的"新的"、"进步的"情节加入到传统戏曲中,以"教育"民众.精英和国家对茶馆戏园的改良和控制揭示了大众文化与精英文化之间、地方文化的独特性与国家文化的同一模式之间的斗争.在国家权力及其文化霸权之下,大众娱乐不可避免地被改变了.但国家要达到控制的目的远非轻而易举,从晚清改革到国民政府的崩溃,成都地方文化和习惯堡垒顽固地坚守着它们的防线,充分显示了近代中国文化变化与持续性同时并存这样一个重要的历史现象.     

城乡一体化地区120急救医疗站点设施区位问题分析——以广东省鹤山市为例

120急救医疗服务的站点选址是基本的设施区位问题.本文以广东省鹤山市为例,开展了关于城乡一体化地区120急救医疗站点区位的优化研究.首先根据2006年鹤山市120呼叫数量的实际数据研究了公众个人满意度随距离的衰减关系;然后在不同的优化原则下构建了两个满意度优化模型;最后.分别假设不同的站点数量设置,对两个模型进行了求解与比较.结果发现基于最小个人满意度最大化的模型Ⅱ虽然在总满意度上表现不佳,但具有较好的公平性,且可以用较少的站点满足给定距离范围覆盖所有的镇.
