基于仰韶水泥的砂岩石窟裂隙灌浆材料物理力学特性研究

为寻找适宜砂岩石窟岩体裂隙灌浆的材料,进行了基于仰韶水泥的砂岩石窟岩体裂隙灌浆材料室内筛选。研究表明,以烧料礓石为胶凝材料,以偏高岭土、石英砂为填料的浆液可作为砂岩石窟裂隙灌浆的初选材料。进一步试验表明,当浆液材料添加总质量10%膨胀剂后,最优的配比为烧料礓石、偏高岭土、石英砂以质量比1∶0.6∶0.4,最佳水灰比为0.5~0.6。针对该配比的灌浆材料开展物理力学特性测试及耐候性试验,结果表明,该种配比的浆液结石体除具有孔隙率大、收缩小、强度好的特点外,还具有较好的抵御温湿度循环、冻融循环及盐碱侵蚀等的能力,是一种较为适宜的砂岩石窟裂隙灌浆材料。研究结果也可为类似石窟岩体裂隙灌浆材料的选择作参考。     

Archaeology in the Context of War: Legal Frameworks for Protecting Cultural Heritage during Armed Conflict

International law provides for a framework for protecting cultural heritage during armed conflict and for punishing those who transgress these principles. If understood within its limitations of dependence on state ratification and enforcement, international law protects cultural heritage by providing guidelines to those who wish to conform and by punishing after the fact those who deliberately destroy cultural heritage. Recent movement toward ratification of the 1954 Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict and its protocols by the major military powers should afford greater protection to cultural heritage in future conflicts.     

华侨房屋权益保护的法律思考：问题与对策

论文以厦门市内侨房处理中的法律问题及现实问题为例,结合现行《物权法》的相关原则及规定,对被改造、征收的华侨房屋之“一房两制”问题、“两权分离”问题、华侨信托代管房之清退问题以及城市侨房的拆迁补偿问题等,进行了分析研究,并提出了相应的法律对策。主要观点有：华侨房屋的所有人对自己享有所有权的房屋具有完全的权利,必须受到《物权法》的保护;因历史原因被“错改”的华侨房屋应当退还给业主,但根据当时的政策规定,对华侨的非住宅房屋,国家已进行了赎买或者改造的房屋,所有权为国家所有,不存在退还产权问题;政府机构对确定为华侨的房屋应主动退还给所有人;对已经拆迁的房屋应当按照法律规定进行补偿;《物权法》规定了财产平等保护的规则,因此华侨房屋权益优先保护的观念和处理方式不再符合《物权法》的规定。     

试论《临时约法》对庙产问题的影响

庙产问题是清末民初时期一个重大的社会问题,它是由庙产兴学政策引起的。《临时约法》的颁布对庙产问题产生了广泛而又深远的影响：一是激发了普通民众的国民意识和平等意识;二是改变了清末以来征用庙产的标准;三是使清末以来征用庙产的行为失去了合法依据;四是赋予普通民众聚集力量的手段。这就使庙产问题迅速复杂化、表面化,促使政府制定相关政策,进而使庙产问题向法制化的方向迈出了重要的一步。     

论居住权的社会价值

“居者有其屋”是每个社会成员的追求,但在我国由于居住权制度的缺位,致使上述理想无法完全实现。从国外关于居住权的立法来看,源自罗马法的居住权是无房者实现其居住目标的有效制度借鉴。本文通过对居住权法律属性的解读,阐述了居住权在现代社会中的价值。     

Ownership matters: Natural resources property rights and social conflict in Sub-Saharan Africa

Empirical tests of the “resource curse” thesis have provided inconclusive evidence for the claim that natural resource abundance increases the risk of social conflict. The present article argues, based on a novel political economy framework and a new data set, that it is important to analyze how states regulate the access to their natural resources to understand the interrelationship between resources and public resistance against resource extraction arrangements. We claim that international rather than state resource ownership fosters the regional protest potential and overshadows the efficiency gains that foreign investment might create. Especially the siphoning of resource rents to international owners instigates resentment among the local population. Distinguishing between private, public, domestic and international ownership arrangements, we assess the effects of natural resources control rights regimes on state repression using new GIS-based data on diamond and gold mines as well as oil and gas fields in Sub-Sahara Africa. Our multilevel analysis shows that repression as an answer to societal dissent is particularly likely in grids hosting international oil companies. Furthermore, we find that international oil firms further state repression especially under insecure property rights.     

Economic autonomy and male authority: female merchants in modern Italy

This paper examines the social role of 'mercantesse' (entrepreneuses), women who, in contemporary Italian society, were the owners of manufacturing and trading activities. The first part is dedicated to the legal aspects, with particular reference to the institution of marital authorization and to the various social standing of three very different personae: the female merchant, the partner wife and the merchant-wife. The second part compares the regulatory aspects of this activity with the concrete reality, on the basis of census data and registrations at the Chambers of Commerce. Generally, the trends which come to the fore are unexpected ones, and are characterized by both the recognition of important and not exclusively economic power, as well as the legal, economic and social limits which conditioned not only access to this kind of activity but also the way in which it was carried out.     

Federal intellectual property policy and the history of technology: The case of NASA patents

This essay explores two closely entwined issues in recent history of federal R&D policy: (a) the disposition of the US government intellectual property (IP), and (b) how to best assess the effectiveness of federal patenting and licensing policies. It does so by examining two decades of patenting policy and practice at the National Aeronautics and Space Administration (NASA). The essay concludes with observations on the limits of our current approach to collecting data on the disposition of federal IP, and an alternative framework for examining the role of IP in the history of modern technology.     

‘Mr Bourne's dilemma’. Consumer culture,property speculation and department store demise: the rise and fall of Bourne and Hollingsworth on London's Oxford Street

This paper explores the twentieth-century rise and fall of the traditional department store Bourne and Hollingsworth in London's Oxford Street as a means of re-examining the historical geographies of metropolitan consumption cultures. The research moves away from a preoccupation with urban retail's novelty and spectacle towards a consideration of the more conventional and conservative kinds of consumption that have been a vital part of the retail ecology of many major cities in the twentieth century. The paper analyses the intersections of different dimensions of the history of metropolitan consumption: with a culturalist focus on consumer identity and urban microgrographies; but also an examination of this as a family-owned, paternalistic business, and as a material space, both as a building designed and refurbished by its owners, management, architects and shopfitters, and as a particular site within the routes and flows of the West End. The final approach to Bourne and Hollingsworth as urban property, as a distinctive form of capital asset in the city, allows a new understanding of the vulnerability of this kind of retailing by the later twentieth century. The study shows that an emphasis on the significance of cultures of consumption provides at best a partial explanation for changes in the landscapes of consumption: it is argued that cities are the sites of complex intersections between cultural practices and other kinds of geography, in this case those of asset values and opportunities for property speculation.     

说“三女为粲”之“粲”本字为“姦”

根据三体等位会意字“形三以示其多”的基本原则和三体等位会意字意义蕴涵中形体意义和属性意义的职能分配规律,得出“粲”的本字应该是“姦”。
