岩石力学性质及可钻性分级研究

岩石力学性质和可钻性是分析和评价岩石抵抗破碎和钻进的基本性质，也是合理选择碎岩工具和工艺的基础。因此，对岩石力学性质和可钻性的深入研究，采用能够反映某种碎岩方式实质的综合力学性质指标评定岩石可钻性，应用数理统计学原理，依据岩石力学性质和可钻性指标，建立表示岩石可钻性的数学模型，并以此模型进行岩石可钻性分级，可及满足岩土工程施工生产的急需。     

多波束关键技术——波束形成原理

换能器阵元的不同排列组合决定其指向性，波束形成是多波束测量的关键技术。文中通过数学计算总结了不同换能器阵进行波束形成的工作原理，并介绍了利用二维DFT进行频域波束形成的一般方法。最后结合现役多波束测深系统，简单解释说明不同系统所采用的波束形成技术。     

岩石在破裂孕育过程中声发射变化特征的物理机制研究

根据声发射原理，并假设岩石中颗粒断裂的总几率符合Ｗｅｉｂｕｌｌ型极值函数，由此导出声发射总数Ｎ与应变能Ｗ，材料断裂构造形状参数ｍ，试样几何尺寸Ｂ及颗粒总数Ｌ的关系。对同一材料的同一试件而言，ｍ对Ｎ的变化形态有显著影响，而应变能的大小则对Ｎ的大小有显著影响，并同时导出声发射率与上述变量及能率的关系。同样，的变化形态受ｍ的制约，的大小则与应变能的大小及能率大小有关。进一步推导还表明，在岩石主破裂前，前兆时间ｔ和的变化不仅与极值应力前后的应变硬化及应变软化程度有关，且与环境刚度（压机刚度）及岩石自身的力学性质有关。摸拟了几条理论曲线，它与实验结果非常一致。     

Enclosure of the urban commons

This is an essay about the territorial enclosure of urban neighbourhoods. It develops the argument that the shared public realms that became regarded as normal in the cities of the 20th century are inherently unstable. More particularly, they are an unstable form of co-ownership domain (condominium). In many different cultures and economies new forms of local territorial governance are emerging to make joint consumption more sustainable. Most of the essay is devoted to exploring this evolutionary argument and is theoretically oriented and illustrated with historical examples. We end with illustrations of urban enclosure from China, a country that has had to discover almost overnight new forms of organisational, institutional and spatial order.     

物权法对节约集约利用土地的法理解析

土地资源具有稀缺性和不可再生性,土地供给日渐紧张,拓展土地利用空间、将土地利用由平面趋向立体化发展的趋势日渐成熟。青岛市崂山区将建设用地使用权分层出让,不但垂范了法规政策,对区域经济的发展也具有很大的现实意义。     

Property matters: Agricultural restructuring and changing landlord-tenant relationships in England

Little research has been conducted on the restructuring activities of tenant farmers in response to changing tenancy legislation and recent CAP reforms. This paper examines the geography of farm tenancy agreements in England since 1995 and presents some findings from postal and telephone surveys on the possible future business trajectories of tenant farmers and the changing nature of landlord-tenant relationships. A clear north-south divide is identified in terms of farm tenancy agreements and a complex array of different tenancy agreements is demonstrated. The relationships between landlords and tenants are changing and the increasing variety of agreements provides evidence of a more fluid (post-feudal) system of agricultural leases. Nevertheless, high levels of uncertainty and negativity characterise tenant farmers’ views on the impacts of CAP reforms. Crucially, the very identity of a tenant farmer is changing, towards an owner-occupier who rents additional land, and there is an urgent need for more detailed research on the ‘consequential geographies’ of farm property rights and the changing nature of landlord-tenant relationships.     

“It’s a gestalt experience”: Landscape values and development pressure in Hawke’s Bay, New Zealand

Demand for both primary residences and second homes in high-amenity areas has led to escalating property values and widespread development pressure in coastal New Zealand. We focus on a major development proposal at Ocean Beach, a greenfield coastal site in the Hawke’s Bay region, and seek to explain the opposition it has provoked. In so doing, we address three questions: first, what landscape values are articulated within the planning process; second, what is the anticipated impact of 1000 new dwellings on those values; and third, how does place attachment figure in the ensuing debates. We address these questions though a thematic analysis of data derived from official reports and proposals, planning submissions, and key informant interviews. We find Ocean Beach to be a place that offers a quintessential coastal experience, often linked to youthful memories. Additionally, the site is valued for its accessibility and wilderness qualities - perceptions heightened by awareness that areas of undeveloped coastline relatively close to population centres are increasingly scarce. We contend that such sites are doubly valuable: in a formal sense, as natural landscapes whose processes and forms receive regulatory protection; and in an informal sense, as sites that generate human meaning, including emotions such as nostalgia, freedom and belonging.

Attainment of ecosystem based governance in European waters—A State property rights regime approach for Ireland

On Ireland's continental shelf, as well as within its Exclusive Economic Zone (EEZ), there are significant biodiversity hotspots including those associated with Cold Water Corals (CWC). Some of these ecosystems enjoy little or no actual protection and are subject to the effects of open access. Sectorally driven initiatives, a recalcitrant attitude to environmental law and inadequate governance, have added to the conditions that have facilitated years of damage by fishers and other actors from many States. A review of the current governance regime, influenced primarily by the Common Fisheries Policy (CFP), is presented. Failings of this regime are highlighted by the destruction of some biodiversity hotspots associated with vulnerable marine ecosystems (VMEs), an externality primarily arising from the effects of deepwater fishing. While exploring some of the principles relating to the institution of property rights, this paper makes a link between property rights, the public trust doctrine and sovereign rights. The paper suggests that such biodiversity systems are the property of citizens of the individual States in whose area of jurisdiction they occur. The paper argues for an Irish State property rights regime as part of an ecosystem approach within a nested institutional architecture. This has important implications for the governance of biodiversity such as that associated with CWC and for the development of an Irish National Oceans Policy.
