SO2与水分综合影响下的云冈石窟砂岩劣化研究

气体污染物SO₂是造成云冈石窟文物本体劣化的重要因素之一。为厘清SO₂与水分耦合作用下的云冈砂岩劣化规律，开展不同SO₂浓度、相对湿度以及降水条件下的室内模拟风化试验，测定试样质量、表面特征和化学成分变化。结果表明：SO₂易与砂岩中的碳酸盐矿物(如方解石)和长石发生化学反应，产物包括CaSO₄·2H₂O、MgSO₄·7H₂O和高岭石等，且随着相对湿度增加，反应程度增大，造成试样的质量、色差值、可溶盐含量上升及硅铝比下降；液态水的参与能显著加快SO₂与砂岩的相互作用过程，不但增加了各项指标的变化幅度，还加大了SO₂入侵深度。研究成果可为砂岩质文物的科学认知和预防性保护提供参考。     

The Role of Engineer-in-Chief and the Introduction of Foreign Hydraulic Dredging Technology and River Conservancy into China, 1890s–1930s

This paper discusses studies of the development of river conservancy in modern China, and the role of engineers-in-chief in river improvement planning on rivers such as the Hai-ho (Haihe) and the Whangpoo (Huangpu). It discusses the introduction of foreign hydraulic dredging technology and management into two major Chinese ports. It then analyses the process by which two agencies of the Chinese government absorbed and adjusted this technology to suit local circumstances in the treaty ports of Tianjin and Shanghai beginning in the 1890s. Without prior experience in river conservancy, the conservancy boards adopted a range of foreign technologies. This allowed them to develop into major institutions that facilitated increasing trade flows between China and the rest of the world. Of particular significance in this process of technological change was the role of the expatriate engineers-in-chief who were employed as chief executive officers of both agencies. They were responsible for establishing the operations of the agencies, accommodating an increasing range of responsibilities such as financial and human resource management, and training Chinese engineers and managers for senior positions until they were ready to replace the expatriate engineers-in-chief after the 1930s.     

Conodonts and tabulate corals from the Upper Ordovician Angullong Formation of central New South Wales,Australia

Zhen, Y.Y., Wang, G.X. &; Percival, I.G., August 2016. Conodonts and tabulate corals from the Upper Ordovician Angullong Formation of central New South Wales, Australia. Alcheringa 41, xxx–xxx. ISSN 0311-5518.

The Angullong Formation is the youngest Ordovician unit exposed in the Cliefden Caves area of central New South Wales. Its maximum age is constrained by a Styracograptus uncinatus graptolite Biozone fauna at the very top of the underlying Malongulli Formation, but the few fossils previously reported from higher in the Angullong Formation are either long-ranging or poorly known. From allochthonous limestone clasts in the middle part of the formation, we document a conodont fauna comprising Aphelognathus grandis, A. solidum, Aphelognathus sp., Aphelognathus? sp., Belodina confluens, Drepanoistodus suberectus, Panderodus gracilis, Panderodus sp., Phragmodus undatus, Pseudobelodina inclinata and Pseudobelodina? sp. aff. P. obtusa, which supports correlation with the Aphelognathus grandis Biozone (late Katian) of the North American Midcontinent succession. The species concepts of Aphelognathus and Pseudobelodina are reviewed in detail. Associated corals are exclusively tabulates, dominated by agetolitids, including Agetolites angullongensis sp. nov., Heliolites orientalis, Hemiagetolites breviseptatus, Hemiagetolites sp. cf. H. spinimarginatus, Navoites sp. cf. N. circumflexa, Plasmoporella bacilliforma, P. marginata, Quepora sp. cf. Q. calamus and Sarcinula sp. Affinities of the coral fauna from the Angullong Formation are closer to faunas from northern NSW and northern Queensland than to the locally recognized Fauna III of late Eastonian age in central NSW. We propose a subdivision of Fauna III to account for this difference, with the late Katian Fauna IIIB characterized by the incoming of agetolitid corals. The currently known distribution of representatives of this group with adequate age constraints suggests that agetolitids possibly originated in North China, subsequently migrating to Tarim, South China and adjacent peri-Gondwanan terranes while also spreading eastward to northern Gondwana, where they progressively moved through eastern Australia to reach the central NSW region by the early Bolindian.

服务于创意生活的博物馆设计

博物馆设计包括建筑设计和展览设计两方面。20世纪,欧洲和美国的博物馆原先丰富的实物展示逐渐被叙事展览取代,后者集空间、媒体、藏品和故事于一身,形成复杂的高感官体验。博物馆应该是一个拥有多样化复杂资源的集合体,为民众的创意生活服务。在服务于商业开发的社会下,博物馆的公共服务观念在渐渐消失。所以我们要重新思考博物馆的作用、责任和社会(或空间)形态。博物馆设计是一项社会艺术,建筑形态是对社会关系和多元经历的积极回应。以研究为导向的博物馆设计能推进博物馆的建设和发展,使之为我们共同的社会增添意义。     

Negotiations of Irish identity in the wake of terrorism: the case of the Irish in Birmingham 1973–74

This article explores the Irish migrant experience in Birmingham during and in the wake of terrorist campaigns carried out in Britain between 1969 and 1975 and attributed to the Irish Republican Army (IRA). Beginning with a discussion of the competencies with which Irishness was associated at the close of the 1960s in England, many of which were hinged on a notion of the Irish predisposition towards violence, the article continues on to take the political, cultural and religious “temperature” of the Irish community in Birmingham between 1969 and 1975, and follows on with a discussion of the specific strategies sought out by Irish immigrants to come to terms with the effect of events such as the “Birmingham Bombings” on their daily lives. Principle findings that emerge from the study indicate that IRA terrorism forced the Irish in Birmingham to engage with and adopt a number of distinct linguistic and cultural strategies in the post-1974 period, the cultivation of which indefinitely altered their relationship with Ireland as “home”, their visibility in the public British sphere and their associational patterns and practices within the migrant enclave.     

Interest Groups,Federalism, and Water Quality in the Great Lakes: Chasing a Moving Target

Federalism often creates additional decisions for interest groups in determining how best to advocate for their policy recommendations in the legislative process. Should they focus their advocacy at the local, state, or national level of government? This article examines interest group behaviors in water quality policy in the Great Lakes region from 1960 to 2000. I evaluate the reasons for interest group decisions about which level of government to target, using historical analysis of Great Lakes water quality policy in the United States and Canada. The results of this analysis show that in many cases groups are influenced in their decision-making based on the level of government that has the greatest jurisdiction over the policy, supporting a neoinstitutional argument.     

DENG DONG,MR. NICE OF YUSHU

During our talk with Danke, he suggested enthusiastically that we interview another person： ＂You＇ve got to talk to him. He＇s been working tirelessly in Yushu for quite a few years, planning the new Yushu and new projects for it. Danke was talking about Deng Dong, Director of the Urban Planning and Design Institute of the China Academy of Urban Planning and Design （CAUPD）. The locals have given him the nickname ＂Mr. Nice of Yushu＇.
